Twelve indigenous male goats, comprising of six intact and six castrated (2.5-3 years; $24.4{\pm}0.62kg$) were assigned evenly into two dietary treatments, viz. $I_0$ and $I_{100}$ and were used to study the effect of supplementation of iodine on the nutrient utilization when their diet contained Leucaena leaf meal. They were offered a conventional concentrate mixture along with Leucaena leucocephala leaf meal, the latter to meet 50% of their crude protein (CP) requirements, and supplemented with either no iodine ($I_0$) or 0.1 mg of iodine ($I_{100}$)/day/animal as potassium iodide for a period of 105 days. Wheat straw given ad libitum was the sole source of roughage. A metabolism trial of 8 days duration was conducted after 90 days of experimental feeding. It was observed that the overall dry matter (DM) intake during experimental period was higher (p<0.05) in $I_{100}$ group as compared to $I_0$ group (508.6 vs. $443.7g\;d^{-1}$). The intake of CP, digestible crude protein (DCP) and metabolisable energy (ME), although non-significant, tended to be higher in the iodine supplemented group, $I_{100}$. Digestibility of dry matter, organic matter (OM), CP, ether extract and crude fiber (CF) did not differ (p>0.05) between the treatments. However, nitrogen retention was higher (p<0.01) in $I_{100}$ than $I_0$ with the values being 2.63 and $1.70g\;d^{-1}$, respectively. No difference (p>0.05) was evident in the retention of calcium and phosphorus between the two groups. The castrated animal exhibited lower DM intake concurrent with higher digestibility of DM and crude fibre (p<0.05), and organic matter and total carbohydrates (p<0.01) when compared to intact ones. It was concluded that supplementation of iodine to leucaena based ration may help in improving the DM intake and nitrogen utilization by goats.

A study was carried out to examine the effect of supplementing urea-sprayed maize stover with incremental levels of Tithonia diversifolia (Tithonia) forage on dry matter (DM) intake, digestibility and live weight changes. Fifteen crossbred bucks were used in a completely randomised design for a duration of 7 weeks. The treatments comprised of a control: the basal diet (maize stover sprayed with 1% urea) plus 100 g maize germ offered alone or supplemented with: 10 (T1), 20 (T2), 30 (T3) or 40% (T4) Tithonia on a dry matter basis. All animals were allowed ad libitum access to water and mineral lick. Supplementing maize stover with Tithonia resulted in increased total DM intake (p<0.05) from 376.7 (control), to 444.1 (T1), 533.1 (T2), 519.7 (T3) and 578.9 g/day (T4) but did not significantly (p>0.05) influence the intake of stover. Diet DM digestibility increased with supplementation with T3 recording the highest value of 66.5% which was 10.6% higher than the control. Supplementation significantly increased daily weight gains (p<0.05). T4 had the highest ADG (43.7 g/day), even though there was no difference between T4 and T3 (35.7 g/day). In goats, Tithonia should be included up to 30% of ration on a DM basis for optimum production. The higher level of inclusion (40%) may be used for higher total output in terms of meat and milk but with few animals.

Background: Diabetes is associated with cancer risk in the aging population. Observational studies have indicated the beneficial effects of metformin against breast cancer, making studies on the anticancer potential of antidiabetic drugs worthwhile. This study investigated cancer incidence in patients on antidiabetic monotherapy. Methods: Using National Health Insurance Service data (2002-2013), a retrospective cohort study that included type 2 diabetes mellitus (T2DM) patients was conducted. Study subjects were enrolled if they were ${\geq}30$ years old, on monotherapy for diabetes, and cancer-free. They were followed up for cancer occurrence or death, until December 31st, 2013. A Cox proportional hazard model analysis was conducted between metformin and sulfonylurea (including meglitinide) users, to determine cancer risk, with adjustment for age, gender, comorbidity index, dyslipidemia, hypertension, and T2DM duration. Results: The number of antidiabetic monotherapy-treated T2DM patients without a history of cancer was 9,554 (metformin, n = 5,825; sulfonylurea, n = 3,225; others, n = 504). During the follow-up period (mean, 2.04; IQR, 3.18 years), the cancer incidence rate was 5.48/100 and 5.45/100 patient-years for metformin and sulfonylurea, respectively. The hazard ratio (HR) for risk of cancer incidence in the metformin group was 0.74 (95% confidence interval [CI], 0.66-0.83; p < 0.0001), compared with sulfonylurea. Additionally, the HRs for risks of lung, liver, and stomach cancer were respectively 0.46 (95% CI, 0.31-0.66; p < 0.0001), 0.41 (95% CI, 0.31-0.54; p < 0.0001), and 0.51 (95% CI, 0.35-0.73; p = 0.0003). Conclusion: Antidiabetic therapy with metformin reduces cancer risk by 26%, specifically for lung, liver, and stomach cancer.

Objective: The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. Methods: Forty-five female Holstein calves (body weight [BW] = $79.79{\pm}0.38kg$) were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration containing 60% (dry matter [DM] basis) of basal starter feed and 40% (DM basis) of forage, but varied in composition of forage source including i) alfalfa (40% DM, AH); ii) alfalfa hay (26.7% DM)+oat hay (13.3% DM; OH); iii) alfalfa hay (26.7% DM)+corn silage (13.3% DM; WS). Results: Dry matter intake was not different among treatment groups (p>0.05). However, BW (p<0.05) and average daily gain (p<0.05) of calves fed AH and OH were greater than WS-fed calves, whereas heart girth was greater in OH-fed calves than those fed AH and WS (p<0.05). Ruminal fermentation parameters including proportion of butyric acid, acetated-to-propionate ratio, concentration of total volatile fatty acid, protozoal protein, bacterial protein, and microbial protein in rumen were the highest in OH (p<0.05) and the lowest in WS. Compared with the AH and WS, feeding oat hay to postweaning calves increased crude protein digestibility (p<0.05), and decreased duration of diarrhea (p<0.05) and fecal index (p<0.05). Conclusion: Our results suggested that partially replacing alfalfa hay with oat hay improved ruminal fermentation, nitrogen utilization, and reduced incidence of diarrhea in post-weaning dairy calves.

Currently, pharmacotherapy is becoming essential for obesity, owing to its expanding and increasing epidemiology. In this review, novel peptide-based drugs of four classes are covered: GLP-1 receptor agonist, GIP/GLP-1 receptor dual agonist, glucagon/GLP-1 receptor dual agonist, and a combination of amylin receptor agonist/GLP-1 receptor agonist. Semaglutide is a next-generation GLP-1 receptor agonist with a longer duration and stronger weight and glucose reduction effects than liraglutide and dulaglutide. In the STEP1 trial, semaglutide 2.4 mg reduced body weight by approximately 15% in people with obesity with similar or milder adverse events than liraglutide 3.0 mg. Tirzepatide, a GIP/GLP-1 receptor dual agonist, also has a long duration and strong weight- and glucose-lowering effect. According to SURPASS-2, 3, and 4, in patients with BMI≥25 kg/m² and type 2 diabetes mellitus (T2DM), tirzepatide 15 mg reduced the initial body weight by >13%. Cotadutide, a glucagon/GLP-1 receptor dual agonist, showed weaker weight-lowering effects than semaglutide and tirzepatide, while it was comparable to that of liraglutide in a phase 2 clinical trial for non-alcoholic fatty liver disease in patients with BMI≥25 kg/m² and T2DM. Additionally, its effect on the liver was noticeable. The long-acting amylin receptor agonist cargrilintide combined with semaglutide can be another effective option for obesity treatment. Even in a small phase 1 trial with a short study period of 20 weeks, cargrilintide 2.4 mg/semaglutide 2.4 mg reduced by 17% of initial body weight in people with BMI 27-39.9 kg/m². In coming several years, semaglutide, tirzepatide, and cargrilintide/semaglutide will become available for obesity treatment in Korea.

Purpose: The purpose of this study was to investigate foot ulcer risk factors, foot care knowledge, and foot care practice in patients with type 2 diabetes. Method: One hundred fifty type 2 diabetic patients were in and out-patients in a large urban hospital. The data were collected using a self-report questionnaire, chart review and foot examination. The questionnaires were developed by the researchers through the experts consultation and literature review. High risk for foot ulcer was evaluated by peripheral neuropathy(PN), peripheral vascular disease(PVD), and prior foot ulcer. Foot risk scores(FRS) means numbers of present risk factors. Results: 31.3% of subjects show 1 FRS, and 13.3% showed 2 FRS. Mean foot care frequency was 3.5 times per week. There were significant differences in foot care knowledge according to DM education (t=2.96, p=.004) and foot care education (t=3.65, p=.001). There were significant differences in the foot care practice activities according to duration of DM (t=3.48, p=.010) and educational levels. Conclusion: There were high proportion of foot ulcer risk among the patients. It is necessary to screen high risk foot ulcer patients and provide practical education for foot care practice of diabetic patients.

This study showed the psychological symptoms, nutritional status and eating behaviors of diabetic patients. General informations on subjects nutritional status were collected by questionnaire, whereas Symptom Check List-90-Revision(SCL-90R) was used for gathering the data related to psychological problem. 34 diabetics in the hospital, aged 49$\pm$10.5 years old, were chosen as the subjects of this study. Their average height was 162.3$\pm$9.4cm and weight was 57.0$\pm$9.5kg. The average period of their suffering from DM was 54.1 weeks. Among, the subjects, 71.0% adapted diet therapy for their disease, whereas 36.7% and 40.7% did diabetic drugs and daily exercise like walking and jogging, respectively, Among 9 psychological symptoms observed, the scores of somatization, depression, anxiety, phobic anxiety and psychoticism were higher than the standard score, however they were not statistically significant. The score of paranoid ideation was lower than standard score. It was statistically significant. As the measure of their clinical status, BMI(body mass index), PIBW(percent ideal body weight) and fasting blood sugar(FBS) were selected 21.6$\pm$2.8, 102.4$\pm$14.8% and 207.8$\pm$19.9mg/이 respectively. The somatization was significantly correlated with subjects duration of DM. Subjects with psychological problems showed wrong eating behaviors. The fasting blood sugar was significantly correlated with the level of depression.

This study investigated the influence of sodium stearoyl-2-lactylate (SSL) emulsifier on the growth performance and nutrient digestibility of growing pigs. For this 56-day long-duration experiment, 80 heads of cross-bred ([Landrace × Yorkshire] × Duroc) pigs with an initial body weight of 23.80 ± 4.87 kg were divided into two (2) treatment groups each fed a different diet: with and without an emulsifier. Each treatment group had 8 replication pens with 5 pigs per pen. Feed treatments were as follows: 1) CON: Basal diet, and 2) SSL: CON + 0.05% SSL. Body weight (BW), average daily gain (ADG), and feed conversion ratio (FCR) were measured for three periods: 0 - 4, 5 - 8, and 0 - 8 weeks. The nutrient digestibility parameters consisting of dry matter (DM) digestibility and nitrogen (N) digestibility were calculated on the 4^th and 8^th week. Based on the results, the SSL supplementation did not show any significant influence on the growth performance parameters during the 0 to 4 and 5 to 8 week phases. For the overall performance, only the FCR (p = 0.048) was significantly different in the emulsifier fed group (SSL) compared to the CON group (T1). DM and N digestibility was also not influenced by the SSL addition in the growing pig diet. Overall, the SSL supplementation showed a limited effect on the growth performance of growing pigs.

While Self-monitoring of blood glucose (SMBG) has been recommended in some diabetes mellitus (DM) patients population according to the 2010 American Diabetes Association (ADA), 2007 Korean Diabetes Association (KDA), 2005 International Diabetes Federation guideline, it is excluded from a routine insurance coverage for outpatients in Korea. The objective of this study is to meta-analyze the impact of SMBG on HbA1c in non insulin-treated diabetes mellitus (NIT) DM patients. Published clinical literatures were identified through electronic database searches from inception and until May 2010. Studies were selected if they met the following inclusion criteria: 1) randomized controlled trials (RCTs), 2) comparing SMBG with non-SMBG in NIT type 2 diabetes, 3) measuring HbA1c as an outcome. Literature qualities were assessed by the Scottish Intercollegiate Guidelines Network Checklist. The mean difference of HbA1c between the 2 groups was pooled from non-heterogeneous 6 RCTs by meta-analysis using Review Manger (RevMan) Version 5.0 program. Pooled results demonstrated that SMBG is associated with a statistically significant improvement in glycemic control (mean HbA1c difference -0.23, 95%CI -0.32, -0.13). Sensitivity analysis showed that glycemic controls were significantly improved in patients with shorter study duration, more frequent self-monitoring, higher baseline HbA1c value, and without prior SMBG experiences. Conclusively SMBG is effective in improving glycemic control in NIT DM patients, but additional evidences from further researches in Korean patients and cost-effectiveness analysis would be necessary to make a suggestion for coverage expansion.

Sixteen adult Barbari bucks were divided into 4 homogeneous groups, each group was offered wheat straw (WS) at levels 75, 100, 125 and 150 per cent of ad libitum intake in a factorial randomized complete block design. All goats were uniformly fed a supplement ($13.5g\;DM/kg\;W^{0.75}$) to fulfill their requirement for protein at maintenance level. The experimental feeding of goats at different levels for 21 days was followed by a digestion trial of 6 days and determination of rate of passage of digesta for 144 h duration, respectively. Intake ($g/kg\;W^{0.75}$) of dry matter (DM), organic matter (OM), digestible DM and digestible OM increased with increase in amount of WS offered. The levels of WS refusals for obtaining upper limit of intake was found to be above 30% of DMO. Concentration of ADF and lignin was significantly lower and CP was higher (p>0.05) in food ingested relative to food offered or refused in response to increasing allowance of WS. Dietary means of particulate rate of passage from rumen, transit time and total mean retention time ranged from 0.032 to 0.036/h, 19.10 to 21.72/h and 58.61 to 61.53/h respectively and did not show significant differences (p>0.05) irrespective of dietary level of WS. The results suggest that DMI and quality of ingested WS would improve with higher rates of offer and refusals (${\geq}30%$ of DMO) without any pronounced effect on passage kinetics of digesta, because of the greater opportunity afforded to goats for selective feeding.
