Association between energy intake and skeletal muscle mass according to dietary patterns derived by cluster analysis: data from the 2008 ~ 2010 Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: This study investigated major dietary patterns among healthy Korean adults using cluster analysis and analyzed the relationship between energy intake and skeletal muscle mass.METHODS: This study was conducted using the data from the 2008 ~ 2010 Korea National Health and Nutrition Survey. The data of 7,922 subjects aged 30 years and over, without any missing values, were included in the final analysis. K-means cluster analyses were conducted to identify the dietary patterns of the study subjects, which were based on the energy intake from 21 food groups using a 24-h recall method. The changes in energy intake with each dietary pattern, according to quartiles of skeletal muscle mass, were investigated.RESULTS: Three dietary patterns were identified for both men and women: ‘Flour, Animal fat’, ‘White rice’ and ‘Healthy mixed diet’. The association between energy intake and skeletal muscle mass for both men and women was significant only in the ‘White rice’ dietary pattern. In the ‘White rice’ pattern, the energy intake increased up to > 300 kcal from the lowest to the highest quartile of skeletal muscle mass after adjustment for covariates. Within the ‘White rice’ pattern, skeletal muscle mass was linearly associated with energy intake in all the age groups in men.CONCLUSION: Energy intake was significantly associated with changes in skeletal muscle mass only in the ‘White rice’ pattern. Furthermore, the degree of association between the change in skeletal muscle mass and energy intake differed according to gender. These results indicate that the association between skeletal muscle mass and energy intake may be specific to Korean people who are accustomed to a traditional Korean diet.

A Vegetable and Fish Dietary Pattern Is Positively Associated with Skeletal Muscle Mass in Korean Men

Isolating the effects of a single nutrient or food in relation to health outcomes including increased skeletal muscle mass is a challenging task because dietary constituents are highly correlated and synergistic. Hence, diet pattern analysis may be used to investigate the role of certain diets in health outcomes. The present study investigated the dietary patterns and their relationship to skeletal muscle mass in Korean adults. Data were extracted from the 2008–2011 Korea National Health and Nutrition Examination Surveys. To explore the dietary patterns of the study subjects, factor analysis was performed using data obtained from a 24-hour recall. The skeletal muscle index according to dietary pattern scores was then investigated to estimate the changes in skeletal muscle mass. Three patterns were initially identified from the factor analysis. Of these vegetables and fish (VF) pattern was the primary factor with high reliability and was a common factor in sex-separated analyses. The VF pattern scores were positively associated with increased skeletal muscle mass in both men and women. Further analysis according to quartile levels of VF pattern scores showed a positive association between skeletal muscle mass and VF pattern in men but not in women. These results suggest that dietary patterns focused on vegetables and seafoods may contribute to increased skeletal muscle mass in Korean men but that sex difference should be considered in nutrition care for skeletal muscle health.

The roles of doctors, nurses, and industrial hygienists in the healthcare management services in Korea: a comparison of the opinions of specialized health management institutions and entrusted enterprises

BACKGROUND: This study aimed to identify the difference of perception about the role of appointing health officers by comparing and analyzing the response of entrustment workplace (EW) and specialized health management institution (SI). This is considered an important aspect of an institutional assessment to improve the quality of health management services. METHODS: A survey questionnaire was mailed to 122 SIs and 319 EWs nationwide. The questionnaire survey was about the general characteristics of SIs and EWs and main occupations for each evaluation item. In total, 81 SIs (66.4%) and 30 EWs responded to the questionnaire. A logistic regression analysis was performed to compare the opinions of SI and EW. RESULTS: Based on the analysis, the items showing statistically significant differences were as follows. Doctors’ main tasks survey: “Guidance on their wearing personal protective equipment (PPE)” (OR: 4.58), “Guidance of improvement of work environment (WE)” (OR: 3.33), etc.; Nurses’ main tasks survey: “Guidance on their wearing PPE” (OR: 3.86), “Guidance for programs on health process in confined space (CS)” (OR: 0.36), “Guidance on the hearing conservation program (HCP)” (OR: 0.28), etc.; Industrial hygienist (IH)‘s main tasks survey: “Guidance of work through inspection (WTI)” (OR: 0.15), “Guidance on the improvement of WE” (OR: 0.32), “Management confirmation of substances used by process and Material Safety Data Sheet (MSDS)” (OR: 0.08), “Guidance on posting or keeping of MSDS and warning signs” (OR: 0.03), “Prevention of dust-induced medical problems” (OR: 0.28), “Guidance for programs of health process in CS” (OR: 0.39), etc. CONCLUSIONS: It is necessary to educate the EWs to recognize the need for physicians to perform tasks, such as wearing a PPE, and instruction to improve WE. As for nurses’ tasks, such as education about the CS and the noise work, educating the nurses of the SI is regarded necessary as the demand of the EWs is considered. With respect to the unique tasks of IH, such as WE management and instructions for wearing PPE, among several other tasks of IH, training should be provided for improved IH recognition.

Total energy intake according to the level of skeletal muscle mass in Korean adults aged 30 years and older: an analysis of the Korean National Health and Nutrition Examination Surveys (KNHANES) 2008–2011

BACKGROUND/OBJECTIVES: Since gain or loss of skeletal muscle mass is a gradual event and occurs due to a combination of lifestyle factors, assessment of dietary factors related to skeletal muscle is complicated. The aim of this study was to investigate the changes in total energy intake according to the level of skeletal muscle mass. SUBJECTS/METHODS: A total of 8,165 subjects ≥ 30 years of age from the Korean National Health and Nutrition Examination Surveys (KNHANES) 2008–2011 were included in the analysis, and multivariate-adjusted regression analyses were performed to analyze the association of the quartiles of sarcopenia index (SI) with energy intake of the study population after adjusting for age and metabolic parameters. RESULTS: The increase in SI quartile was in proportion to the gradual decrease in systemic lipids and the anthropometric measurement of fat accumulation (P < 0.001). Subjects in higher SI quartiles tended to consume more total energy and energy-producing nutrients than those in lower quartiles (P < 0.001). After age, body weight, alcohol consumption, and metabolic parameters were adjusted in the analysis, total energy intake gradually increased according to the increase in SI quartile, and the association between total energy intake and SI was more pronounced in men. However, the risk (odd ratio) of having a low SI was not affected by any single macronutrient intake. CONCLUSIONS: In this study, total energy intake was positively associated with SI and relative skeletal mass in both men and women. However, no significant association or a weak association was observed between any single macronutrient intake and skeletal muscle mass. The data indicated that acquiring more energy intake within the normal range of energy consumption may help to maintain skeletal muscle mass.

Characteristics of occupational musculoskeletal disorders of five sectors in service industry between 2004 and 2013

BACKGROUND: ‘Work related musculoskeletal disorders (WRMSDs)' have been mostly reported in the manufacturing industry but recently the occurrence of industrial injuries has been constantly increasing in the service industry. This research is going to analyze the data about workers' compensation for WRMSDs in five different service sectors and identify characteristics of occupations with the highest approved occupations. METHODS: According to the data released from the Korea Worker's Compensation & Welfare Service, the overview of 12,730 cases of workers' compensation for WRMSDs in five service sectors from 2004 to 2013 is going to be analyzed and the source data is going to be classified by the Korean Standard Classification of Occupations to select the top five occupations that have the highest number of approval. RESULTS: After selecting each five occupations from the service sector that have work related musculoskeletal disorders, the result showed that the occupation with the highest number of approval in the health and social care sector were the early childhood educators, cooks in the school canteens in education services sector, garbage collectors in the sanitation and similar services sector, deliverymen in wholesale and retail, consumer goods repair and building cleaners in general management businesses such as those in building maintenance. The major event observed in the top five occupations was the overexertion and reaction as a cause of WRMSDs. The day when the WRMSDs mostly occurred was on Monday and the most likely time was 10 am. The median days away from work and lost working days are 29–90 days and 0–50 days respectively. The difference in each occupation was observed in year of service, age, and gender. CONCLUSIONS: 83.21% of the approved cases of workers' compensation for WRMSDs occurred in the top 25 occupations in all of the five service sectors, which meant that the approval of workers' compensation is concentrated in specific occupations. This research is going to suggest preventive measures for work related musculoskeletal disorders in the service industry and to help prioritize the preventive measures.

Nutritional Status of Korean Children and Adolescents with Attention Deficit Hyperactivity Disorder (ADHD)

Attention deficit hyperactivity disorder (ADHD) has been associated with an elevated risk for obesity but this seems to be paradoxical to the fact that many youths with ADHD have symptoms of hyperactivity. People diagnosed with ADHD tend to have a high risk of developing undesirable diet habits and consequently have health related problems. However, less attention has been paid to obesity in ADHD while many efforts have been devoted to the prevention of childhood obesity in mentally normal people. Hence the purpose of this study was to explore the nutritional status and life habits of children and adolescents with ADHD (n = 76) based on degree of obesity by utilizing the Korean National Health and Nutrition Examination Survey (KNHANES) data from 2005–2013. As results the levels of blood pressure, total triglycerides and the fat intake relative to total energy intake in overweight ADHD group were higher than those in normal weight group. Interestingly, overweight ADHD subjects consumed significantly less amount of iron compared to normal weight ADHD subjects and the level of serum ferritin was lower in the overweight ADHD group (59.0 ng/mL) than in the normal weight ADHD group (47.9 ng/mL). After adjusting total energy intake, total vegetable consumption was 14.3% lower in overweight group compared to the consumption in normal weight group. These results indicate a plausible relationship of iron status and obesity in ADHD subjects but this relationship may not be specific to ADHD. A future study with case-control design is necessary to investigate the association of obesity, nutrient intake, and cognitive/mental status of ADHD.

Ethical Attitudes according to Education and Clinical Experience of Do-Not-Resuscitate (DNR) / 한국호스피스완화의료학회지

PURPOSE: Although a Do-Not-Resuscitate (DNR) order is widely in use, it is one of the challenging issues in end-of-life care. This study was conducted to investigate attitudes toward DNR according to education and clinical experience. METHODS: Data were collected using a structured questionnaire comprising 30 items in a tertiary hospital in Seoul, Korea. RESULTS: Participants were 238 nurses and 72 physicians. Most participants (99%) agreed to the necessity of DNR for reasons such as dignified death (52%), irreversible medical condition (23%) and patients' autonomy in decision making (19%). Among all, 33% participants had received education about DNR and 87% had DNR experience. According to participants' clinical DNR experience, their attitudes toward DNR significantly differed in terms of the necessity of DNR, timing of the DNR consent and post-DNR treatments including antibiotics. However, when participants were grouped by the level of DNR education, no significant difference was observed except in the timing of the DNR consent. CONCLUSION: This study suggests that the attitudes toward DNR were more affected by clinical experience of DNR rather than education. Therefore, DNR education programs should involve clinical settings.

Functional recovery of mandibular high condylar fracture patient with immediate provisional implant: case report

Treatment methods of mandibular condylar fracture were conservative and surgical method. Surgical method of mandibular high condylar fracture was very difficult because approach and internal fixation of small size fracture fragment were difficult. So there is a tendency to select conservative method over surgical method for guiding a stable occlusion and avoiding TMJ disorder and growth disturbance, minimizing pain and deviation during function. But, in case of mandibular high condylar fracture patient who has no biting teeth on posterior teeth area, guiding a stable occlusion and conservative functional treatment were very difficult. In this case, patient was 62years old male. He had fracture of mandibular symphysis, right mandibular body, left mandibular high condyle. We treated the patient for mandibular symphysis and right mandibular body fracture area with surgical method. But left mandibular high condylar fracture area was difficult to treat with surgical method. So we selected a conservative functional method on left mandibular high condylar fracture area. We intended recovery of vertical dimension and stable occlusion with implantation of immediate provisional implant on maxillar and mandibular posterior teeth area, and temporary crown. And then patient did mandibular functional movement and his mandibular function was recoverd.

Clinicostastical study of inpatients of abscess in fascial spaces for the last 5 years

One of the most difficult problems to damage in dentistry is an odontogenic infection. These infections may range from low-grade, well-localized infections that require only minimal treatment to a severe, life-threatenig fascial space infection. Although the overwhelming majority of odontogenic infections are easily managed by minor surgical procedures and supportive medical therapy that includes antibiotic administration, the practitioner must constantly bear in mind that these infections may become severe in a very short time. We made an investigation was targeting on 78 male and 47 female patients (125 patients in total) who had been hospitalized because of the fascial space abscess on the oral and maxillofacial area and gained a complete recovery in Daegu Catholic University Hospital, Oral and Maxillofacial Surgery from January 1999 to December 2003. By tracing their charts, we could grasp the characteristics such as age, gender, the time of breakout and specific areas of the attacks, making a conclusive study of the statistical analysis and finally, we could reach conclusions. Now, we report the conclusion from the investigation with the literature. The proportion of males and females was approximately 3 to 2, and in age group, patients under 10 years old marked the highest, 22.4%. The patients between the age of 10 and 40 were only 14.4%, yet those who were between 40 and 80 marked 53.6% in contrast. In the monthly distribution, the order was Dec.(13.6%)-Sep.(12%)-Jan.(10.4%) and in seasonal distribution, it was winter(30.4%)-fall(28%)- summer(24.4%)- spring(19.2%). Considering the medical history, D.M. was the highest which was 30.3%, hypertension marked 24.4%, and the patients with both D.M. and hypertension were 9.0%. The major cause of infection of oral and maxillofacial areas was odontogenic infection, which marked about 96%, and especially the cases related to dental caries occurred most frequently, which was 51.2%. In the number of relaxed fascial space, single fascial space was 81.6%, and in the degree of relaxation of fascial space, the buccal space abscess marked 40.8%, following submandibular space abscess, which was 30.4%.
