Objectives This study sought to investigate the relationship between age, sex and alterations in levels of % carbohydrate-deficient transferrin (%CDT) and gamma-glutamyl transferase (GGT) in patients admitted with alcohol dependence. Methods The study retrospectively enrolled 187 patients who were diagnosed with alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders-Fourth edition (DSM-IV) and were admitted into a closed ward in Hallym University Hangang Sacred Heart Hospital from 2009 to 2012 and Hallym University Kangnam Sacred Heart Hospital from 2012 to 2017. Demographic factors (age, sex) and biochemical markers [%CDT, GGT, mean corpuscular volume (MCV), aspartate transferase (AST), alanine transferase (ALT)] were collected by reviewing medical records. Alterations in the levels of %CDT and GGT in different groups for each demographic factor were compared after correcting for confounding variables (age, initial %CDT, GGT, MCV, AST, ALT). Results Decreased %CDT and GGT were observed during the period of abstinence after admission. The normalization period for %CDT increased with age, while the normalization period for GGT was longer in female patients. Conclusions These results suggest that alcohol-dependent patients that vary in age have different alterations in %CDT, while different sexes have different alterations in GGT. Age and sex can be potential indicators of treatment response after abstinence in patients with alcohol dependence. Further studies are needed to evaluate the relationship between these factors with regards to physiological and hematological changes in alcohol dependence.

Objective: Due to current selection practices for increased egg production and peak persistency, the production profile, age at maturity, and body weight criteria for commercial layers are constantly changing. Body weight and age at the time of photostimulation will thus always be the factors that need to be adequately addressed among various production systems. The current study was carried out to determine the effects of pullets' body weight (low, medium, and heavy) on their performance, welfare, physiological response, and hormonal profile. Methods: With regard to live weight, 150 16-week-old pullets were divided into three groups using a completely randomized design (CRD) and held until the 50th week. One-way analysis of variance was used to evaluate the data under the CRD, and the least significant difference test was used to distinguish between treatment means. Results: In comparison to the medium and light birds, the heavy birds had higher body weight at maturity, an earlier age at maturity, and higher egg weight, eggshell weight, eggshell thickness, egg yolk index, breaking strength, egg surface area, egg shape index, egg volume, and hormonal profile except corticosterone. However, the medium and light birds had lower feed consumption rates per dozen eggs and per kilogram of egg mass than the heavy birds. Light birds showed greater body weight gain, egg production, and egg specific gravity than the other categories. At 20 weeks of age, physiological response, welfare aspects, and catalase were non-significant; however, at 50 weeks of age, all these factors-aside from catalase-were extremely significant. Conclusion: The findings of this study indicate that layers can function at lower body weights during photostimulation; hence, dietary regimens that result in lighter pullets may be preferable. Additionally, the welfare of the birds was not compromised by the lighter weight group.

Parenteral nutrition (PN) is effective and relatively safe method providing nutrients to patients with a nonfunctioning or insufficiently functioning gastrointestinal tract via peripheral or central vein. In last several decades, useful steps have been taken in the understanding of nutritional needs, physiological changes and complications of intravenously fed patients. PN includes amino acids, glucose, lipids, electrolytes, vitamins, iron, minerals and trace elements, and must be based on individual circumstances such as patient's age, health status and disease. The purpose of this review is to introduce overall components and recent updates of parenteral nutrition.

Purpose: This study was to identify factors that influence the health care needs of that over 65 years of age in Mokpo, Korea. Method: The data was collected from June 2002 to September 2002. The subjects were 120 homebound solitude elderly(age=76.8). Subjects were interviewed with structured questionnaire in order to identify the health care needs, health variables (perceived health status, risk of malnutrition, K-IADL), psychological variables(self-esteem, depression) and demographic variables. physiological health variables (height, weight, blood pressure, pulse, blood sugar)were assessed after the interview. Result: In general perceived health status was poor, risk of malnutrition was high, number of disease was 3 disease, self-esteem was low but depression was high and health care needs were relatively high. Among the elderly education & counseling needs topped the list. In regression analysis, health care needs were significantly influenced by IADL(23%), duration of solitudes(4%), sex(3%), and education(l%). These variables explained 31% of the variances in health care needs. Conclusion: The result identified that health care needs should be a considered in IADL, female, duration of solitudes and education for the solitude elderly.

Children are not small adults and there is a need to carry out specific trials that cannot be performed in adults. In general, children (minors) are unable to consent but their assent should be obtained using age appropriate information. Institutional Review Board (IRB) need paediatric expertise to balance the benefits and risks of research in children. The lack of consent has implications on the design, analysis and the choice of comparators used in the trials, which should only be performed by trained investigators with paediatric experience. Pain, fear, distress and parental separation should be prevented and minimised when unavoidable. The children requires even more careful review. Children represent a vulnerable population with developmental, physiological and psychological differences from adults, which make age- and development- related research important for their benefit. Finally, criteria for the protection of children in clinical trials therefore need to be laid down. Specific protection should be defined for research performed in children, at all stages and ages.

Samples of blood were taken from 293 cows and heifers in Koheung, Chonnam, which was dsignated as a place for breeding pure-bred Korean native cattle. Each animal was examined clinically and parasitologically and with the history available considered to be normal at the time of blood collection. The hematology and biochemistry values were determinded, and comparisons were made between three age groups, using the results obtained. All the values obtained were within physiological range : except the alanine aminotransferase values which were higher(P<0.05) in young than in mature or old group of cattle, no significant differences were notred between age groups.

The change of sleep pattern is one of the most often altered normal physiological functions in elderly people. Besides normal change of sleep, insomnia and sleep apnea syndrome (SAS) are (one of) the main complaints. In addition, parasomnia is also frequent in this age group. Several parasomnias frequently found in the elderly are reviewed. Periodic limb movements in sleep (PLMS), restless legs syndrome (RLS), and REM sleep behavior disorder are the most frequent parasomnias in old age. Most parasomnias could be diagnosed by polysomnography, and be treated easily. Therefore, early and precise diagnosis and management for parasomnia in aging people are needed.

Objective: This study aimed to determine the effect of intermittent feeding and cold water on performance and carcass traits in broiler chickens between 4 to 6 wk of age exposed to daily high temperature. Methods: Broilers were assigned to four treatment groups according to a 2×2 factorial design between 22 to 42 d of age (80 broilers per treatment, 4 replications). Broilers were divided into two main groups as feeding type (ad-libitum [AL] and intermittent [IF] for 6 h daily) and sub-groups as water temperature (normal [NW], 24.9℃ and cold [CW], 16.4℃). Heat treatment was applied between 11.00 to 17.00 h daily between 22 to 42 d of age. Results: Live weight at 6th wk was not affected by feeding type and water temperature, but the live weight was significantly higher in IF chickens at the 5th wk (p<0.05). Average weekly gain of IF broiler chickens were higher compared to AL group at 4, 5, and 6 wk of age (p< 0.05). Although feeding type did not affect feed intake in 4 and 5th wk, feed intake was higher in IF chickens at 6th wk (p<0.01). In addition, feeding type and water temperature did not affect feed conversion ratio and interactions were not significant (p>0.05). Water temperature had no significant effect on heart, liver, gizzard, and abdominal fat percentages (p>0.05). Conclusion: It is concluded that IF increased the average weekly gain in chickens reared under daily heat stress for 6 h between 22 to 42 d of age. IF in hot environmental conditions slightly increased performance without adversely affecting health, welfare, and physiological traits, whereas CW implementation had no significant effect on performance. It can also be said that IF suppresses a sudden increase in body temperature depending on age and live weight.
