BACKGROUND: We hypothesized that there was a relationship between body weight change and bronchodilator response (BDR) in patients with chronic renal failure (CRF) on hemodialysis (HD). Several mechanisms such as pulmonary edema due to water retention or increased permeability of alveolar capillary may play a important role in pulmonary function impairment and bronchial hyperresponsiveness in patients with CRF on HD. But, no studies have been published concerning BDR in patients with CRF on HD. This study was aimed to know the immediate effect of hemodialysis on pulmonary function and BDR in patients with CRF on HD. METHODS: This study included 30 patients with CRF on HD. We collected data including age, sex, height, pretibial and pedal pitting edema, interdialysis weight gain, postdialysis weight loss , underlying diseases, duration of HD, FEV1, FVC, FEV1/FVC, and BDR before and after HD. RESULTS: Interdialysis weight gain of the patients was 3.4 +/- 1.0 kg, and postdialysis weight loss was 3.2 +/- 0.7 kg. Before HD, FEV1, FVC, and FEV1/FVC of the patients were 89 +/- 22%, 86 +/- 19% of predicted, and 87 +/- 10 %. After bronchodilator inhalation, these parameters were changed to 95 +/- 22%, 90 +/- 19% of predicted, and 88 +/- 9% respectively. BDR was positive in 15 patients. After HD, FEV1, FVC, and FEV1/FVC of the patients were 100 +/- 23%, 94 +/- 18% of predicted, and 88 +/- 11%. After bronchodilator inhalation, these parameters were changed to 102 +/- 23%, 96 +/- 18% of predicted, and 89 +/- 8% respectively. BDR was positive in 9 patients. CONCLUSION: First, HD increases FEV1, FVC, and FEV1/FVC but little affects BDR. Second, there is no correlation between postdialysis weight loss and increases in FEV1, FVC, and FEV1/FVC after HD. Third, there is also no correlation not only between interdialysis weight gain and BDR before HD but between postdialysis weight loss and BDR after HD.

BACKGROUND: Low body weight was one of the risk factors of osteoporosis. Little is known about the correlation between body weight change and bone mineral density (BMD) in Korean women. Therefore, this study was designed to reveal the impact of body weight change on BMD of the lumbar spine in perimenopausal women. METHODS: 105 healthy perimenopausal women aged between 44 and 50 years old were enrolled from August 2002 to March 2009. BMD was measured by dual energy X-ray absorptiometry. Partial correlation coefficients between body weight change and BMD change were calculated after the adjustments for several variables. BMD changes among groups based on BMI and the percentage change in body weight during 1-year follow-up period were compared. RESULTS: At both baseline and year 1, BMD of lumbar spine tended to be associated more with body weight. There was a significant association between body weight change and BMD change in lumbar spine during 1-year follow-up period. The weight gain group relatively showed an increase in BMD of lumbar spines than weight loss group. There was no BMD change in BMI less than 23 kg/m2 group, but in case of BMI more than 23 kg/m2 group, BMD in weight gain group increased more than the weight maintaining group. CONCLUSION: This study demonstrated that body weight change is associated with change in BMD of lumbar spine in perimenopausal women especially if they are overweight.

3.Rationale, Feasibility and Acceptability of Ketogenic Diet for Cancer Treatment.
Hae Yun CHUNG ; Yoo Kyoung PARK
Journal of Cancer Prevention 2017;22(3):127-134
Ketogenic diet has been used for more than 80 years as a successful dietary regimen for epilepsy. Recently, dietary modulation by carbohydrate depletion via ketogenic diet has been suggested as an important therapeutic strategy to selectively kill cancer cells and as adjuvant therapy for cancer treatment. However, some researchers insist ketogenic diet to be highly undesirable as ketogenic diet may trigger and/or exacerbate cachexia development and usually result in significant weight loss. This review revisits the meaning of physiological ketosis in the light of this evidence and considers possibility of the use of ketogenic diet for oncology patients. Article search was performed from 1985 through 2017 and finally 10 articles were analyzed. The review focused on the results of human trials for cancer patients and checked the feasibility of using ketogenic diet for cancer patients as adjuvant therapy. The main outcomes showed improvement of body weight changes, anthropometric changes, serum blood profiles, and reduction in novel marker for tumor progression, TKTL1, and increase of ketone body. Lactate concentration was reduced, and no significant changes were reported in the measurements of quality of life. Ketogenic diet may be efficacious in certain cancer subtypes whose outcomes appear to correlate with metabolic status, but the results are not yet supportive and inconsistent. Therefore, it warrants further studies.

BACKGROUND: Menstrual irregularity is an indicator of endocrine disorders and reproductive health status. It is associated with various diseases and medical conditions, including obesity and underweight. We aimed to assess the association between body weight changes and menstrual irregularity in Korean women. METHODS: A total of 4,621 women 19 to 54 years of age who participated in the 2010 to 2012 Korea National Health and Nutrition Examination Survey were included in this study. Self-reported questionnaires were used to collect medical information assessing menstrual health status and body weight changes. Odds ratios (ORs) and 95% confidence interval (CI) were calculated to evaluate the association between body weight changes and menstrual irregularity. RESULTS: Significantly higher ORs (95% CI) were observed in the association between menstrual irregularity and both weight loss (OR, 1.74; 95% CI, 1.22 to 2.48) and weight gain (OR, 1.45; 95% CI, 1.13 to 1.86) after adjusting for age, body mass index, current smoking, heavy alcohol drinking, regular exercise, calorie intake, education, income, metabolic syndrome, age of menarche, parity, and stress perception. Of note, significant associations were only observed in subjects with obesity and abdominal obesity, but not in non-obese or non-abdominally obese subjects. U-shaped patterns were demonstrated in both obese and abdominally obese subjects, indicating that greater changes in body weight are associated with higher odds of menstrual irregularity. CONCLUSION: We found a U-shaped pattern of association between body weight changes and menstrual irregularity among obese women in the general Korean population. This result indicates that not only proper weight management but also changes in body weight may influence the regulation of the menstrual cycle.

5.Correlates of the Pregnancy Experience and Attitude regarding Weight Change during Pregnancy in Primigravida Women
Korean Journal of Women Health Nursing 2019;25(2):143-153
PURPOSE: We aimed to examine the correlations between pregnancy experience and attitude regarding weight change during pregnancy. METHODS: This correlative study was conducted from July 2017 to October 2017 by involving 156 primigravida women who were over pregnancy 20 weeks in Seoul and Gyeonggi-do province. Data were collected using a questionnaire, which included questions on demographic data, experience during pregnancy, and attitude regarding weight change during pregnancy. Descriptive statistics were calculated. Also, independent t-test, ANOVA, and Pearson's correlation coefficients were used for data analysis. RESULTS: The mean age of the participants was 30.62 years and their score of attitude regarding weight gain during pregnancy was low. Moreover, a significant correlation was found between the pregnancy experience and attitude regarding weight gain during pregnancy in primigravida women. CONCLUSION: As a result of analyzing the correlation between pregnancy experience and attitude towards weight gain during pregnancy, it is apparent that attitudes toward weight change are different according to experience during pregnancy in women. Based on these results, it can be concluded that nursing intervention programs are necessitated to enhance the attitude of pregnant primigravida women towards pregnancy and weight gain.

OBJECTIVE: The aim of this study is to assess the relationships between maternal plasma and umbilical cord leptin concentrations and their effects on newborn birth weights, maternal body mass indices and fetal sex in term normotensive (NT) and preeclampsia (PE) women. METHODS: Blood samples were obtained at delivery from 20 NT group and another 20 from PE group of at least 36 weeks of gestation. And the umbilical cord samples were also taken from their newborns at birth. Plasma leptin levels were determined in both groups using a human recombinant leptin 125-I radioimmunoassay. RESULTS: Mean maternal plasma and umbilical cord leptin concentrations were 16.16+/-2.05 ng/ml and 7.11+/-1.01 ng/ml in NT group, 17.09+/-1.67 ng/ml and 8.55+/-6.63 ng/ml in PE group, and there was no statistical significances among them. The differences of leptin concentrations in maternal plasma and umbilical cord according to baby sex were not significant in both NT and PE groups. Plasma leptin concentrations were related with maternal weight gain and BMI in NT group and with body weight in PE group. The BMI and birth weights of the neonates have significant effects on the umbilical cord leptin concentrations in both NT and PE groups. CONCLUSION: In this study, no correlation was found between maternal plasma and umbilical cord leptin concentrations in both NT and PE groups. But maternal plasma leptin concentrations had positive correlations with maternal body weight, BMI, and body weight changes during pregnancy in both NT and PE groups. There were also positive correlations among umbilical cord leptin concentrations, BMI and birth weights of the neonates of NT and PE groups term. Therefore umbilical cord leptin is considered to be the index of fetal birth weight.

OBJECTIVE: Weight gain is one of the troublesome adverse reaction to clozapine treatment. This problem can lead to poor adherence to treatment. Clozapine-induced weight gain may be associated with genetic predisposition. Recent studies have shown that a polymorphism of the promoter region of the serotonin 5-HT2C receptor gene is associated with antipsychotic-induced weight gain. This study is to investigate the association of clozapine-induced weight gain with -759C/T polymorphism of serotonin 5-HT2C receptor promoter gene in schizophrenic patients. METHODS: Fifty three patients with schizophrenia were included in this study. The subjects were divided into two groups according to body weight change between the start and 10 weeks of clozapine. The cutoff level of weight change is 5% increase of initial body weight. Genotypes of -759C/T polymorphism were identified from AciI-digested fragments of two-primer products amplified by polymerase chain reaction corresponding to -885 to -634 of the serotonin 5-HT2C receptor gene promoter region on chromosome X. RESULTS: There were no differences of baseline variables between patient groups with and without weight gain. 4 of 32 male patients and 6 of 21 female patients had -759T allele, respectively. The authors found that patients with -759T allele had tendency to show less weight gain than those without this allele. CONCLUSION: These findings suggest that clozapine- induced weight gain may be associated with genetic predisposition in schizophrenic patients.

BACKGROUND/OBJECTIVES: Relocation to new environments can have a negative impact on health by altering body weight and dietary patterns. This study attempted to elucidate changes in body weight, food security, and their current food and nutrient consumption in adult North Korean refugees (NKR) living in South Korea (SK). SUBJECTS/METHODS: This study analyzed data on 149 adult NKR from a North Korean refugee health in SK cohort at four time points (leaving North Korea, entering SK, first examination, and second examination). Body weight was self-reported at the two earlier time points and directly measured at the two later time points. Food security, diet-related behaviors (dietary habits and food consumption), and sociodemographic information were obtained using a self-administered questionnaire. Nutrient intake information was obtained by one-day 24-hour recall. Statistical analyses were performed with SPSS ver 23.0. RESULTS: Body weight increased during relocation by an average of 4 kg, although diversified patterns were observed during the settlement period in SK. Approximately 39.6% of subjects maintained their body weight between the first and second examinations, whereas 38.6% gained and 22.1% lost at least 3% of their body weight at the first examination by the second examination. Food security status improved from 12.1% food secure proportion to 61.7%. NKR showed generally good food and nutrient consumption (index of nutrient quality: 0.77–1.93). The body weight loss group showed the most irregular meal consumption pattern (P < 0.05), and eating-out was infrequent in all three groups. Consumption frequencies of food groups did not differ by group, except in the fish group (P = 0.036). CONCLUSION: This study observed considerable body weight adjustment during the settlement period in SK after initial weight gain, whereas food security consistently improved. More detailed understanding of this process is needed to assist healthy settlement for NKR in SK.

OBJECTIVE: Oxidative stress may be an important pathogenic mechanism in the obesity and metabolic syndrome. The aims of this study was to assess the possible association between the oxidative stress related Glutathione S-Transferase genes (GST-M1, GST-T1, and GST-P1) variants and the olanzapine-induced weight gain in Korean schizophrenic patients. METHODS: We categorized 78 schizophrenic patients into two groups the more than 7% weight gain from baseline (weight gain > or =7%) and the less weight gain (weight gain <7%) groups according to weight change between before and after long-term olanzapine treatment (440+/-288 days). All participants were genotyped for the GST-M1, GST-T1 and GST-P1 genes. Differences in allele frequencies between cohorts with different body weight changes were evaluated by a chi-square analysis and Fisher's exact test. The multifactor dimensionality reduction (MDR) approach was used to analyze gene-gene interactions. RESULTS: Mean body weight gain was 5.42 kg. There was no difference in the null genotype distribution of GST-M1 and -T1 between subjects with body weight gain > or =7% compared to subjects with body weight gain <7% (p>0.05). No significant difference in GST-P1 genotype and allele frequencies were observed between the groups (p>0.05). MDR analysis did not show a significant interaction between the three GST gene variants and susceptibility to weight gain (p>0.05). CONCLUSION: These findings do not support a relationship between the genetic variants of three GST genes (GST-M1, -T1 and -P1) and weight gain in Korean schizophrenic patients receiving olanzapine treatment.
