Abstract. The responses of plasma glucose, insulin, C-peptide and glucagon to an infusion of human β-endorphin (0.5 mg/h) were studied in 10 formerly obese subjects who had lost 35 kg by dieting (body mass index <25) and compared with those of 10 normal-weight control (body mass index <25) and 10 obese (body mass index >30) subjects. The fasting plasma concentrations of β-endorphin were significantly higher in both the obese and the post-obese group than in the control group. In both obese and post-obese subjects, the infusion of β-endorphin caused significant increases in peripheral plasma glucose, insulin, C-peptide and glucagon concentrations. In the control group, matched for age, sex and weight with the formerly obese group, there was no appreciable change in plasma insulin and C-peptide concentrations during the infusion of β-endorphin, but the rise in plasma glucose was more sustained. Thus, 1. the increased plasma β-endorphin concentrations found in human obesity are not corrected by normalization of body weight; and 2. formerly obese, normal-weight subjects behave as obese subjects in their metabolic and hormonal responses to β-endorphin infusion. The alteration of the opioid system in human obesity may play some role in the predisposition to weight gain.

Objective: The objective of this study was to discover the effect of Japan water therapy with cinnamon on body composition in overweight and obese subjects. Methods: The study was conducted with 36 subjects divided into three groups, namely, Group A – water therapy with cinnamon (n=12), Group B – water therapy (n=12), and Group C – warm water (n=12), where Groups A and B were test groups and Group C was a control group. This study was carried out for 8 weeks. Body weight, waist/hip ratio (WHR), and body mass index (BMI) were measured every 15th day. Data were statistically analyzed by mean, standard deviation, and paired t-test using Getcalc.com Results: Out of all the groups, Group A showed desirable reduction in weight, WHR, and BMI, but statistically it was non-significant on WHR. Similarly, Group B had non-significant result with content to WHR but showed a moderate reduction in all categories. However, Group C as a control group both had either constant or minimal reduction in WHR and BMI being statistically non-significant. Conclusion: The findings of the study concluded that consumption of Japan water therapy with cinnamon helps in reduction of weight, WHR, and BMI within 8 weeks. Plain water therapy only had a moderate effect on reducing body composition in the same duration of time.

The Impact

It has been acknowledged that excess body weight increases the risk of colorectal cancer (CRC); however, there is little evidence on the impact of body mass index (BMI) on CRC patients’ long-term oncologic results in Asian populations. We studied the influence of BMI on overall survival (OS), disease-free survival (DFS), and CRC-specific survival rates in CRC patients from the administrative claims datasets of Taiwan using the Kaplan–Meier survival curves and the log-rank test to estimate the statistical differences among BMI groups. Underweight patients (<18.50 kg/m2) presented higher mortality (56.40%) and recurrence (5.34%) rates. Besides this, they had worse OS (aHR:1.61; 95% CI: 1.53–1.70; p-value: < 0.0001) and CRC-specific survival (aHR:1.52; 95% CI: 1.43–1.62; p-value: < 0.0001) rates compared with those of normal weight patients (18.50–24.99 kg/m2). On the contrary, CRC patients belonging to the overweight (25.00–29.99 kg/m2), class I obesity (30.00–34.99 kg/m2), and class II obesity (≥35.00 kg/m2) categories had better OS, DFS, and CRC-specific survival rates in the analysis than the patients in the normal weight category. Overweight patients consistently had the lowest mortality rate after a CRC diagnosis. The associations with being underweight may reflect a reverse causation. CRC patients should maintain a long-term healthy body weight.

BACKGROUND: Adolescence is associated with many physical changes, it is described as a period when body weight changes and is likely to become worrying for many adolescents. AIM: This study aims to evaluate associations between body weight perception and body mass index (BMI) among a population of female adolescents. METHODS: A cross-sectional school-based study was conducted from February to May 2017 among 12–19 years olds adolescents (n = 415) from high and middle school. BMI for age percentiles was calculated using the WHO AnthroPlus. Body weight perception was determined using an anonymous questionnaire. RESULTS: The prevalence of misconception of body weight was 60%. The prevalence of misconception was positively associated with the participants age (p < 0.001), the occurrence of menarche (p < 0.05), the increasing of BMI (p < 0.001), and with habits diet satisfaction (p < 0.05). Overweighed participants and who’s with normal weight were more likely to perceive their weight incorrectly (p < 0.05). Furthermore, approximately 2.9% of participants underestimated their true body weight and 57.1% overestimated their weight. However, all participants with underweight had correctly perceived their body weight. Logistic regression showed that predictor factors of misconception weight were participant’s age and BMI. CONCLUSION: It is recommended to improve healthy programs in schools aimed at preventing body weight perception and eating problems among adolescents.

Abstract. To investigate whether short-term fasting affects the pituitary-testicular axis in obese subjects, 9 massively obese men (Body Mass Index 39.0 ± 1.3, mean± sem) were given two identical iv GnRH tests, the first (control) after an overnight fast, the second after 56 h of food deprivation. Short-term fasting augmented the GnRH-induced LH incremental area by 26%(1317±251 vs 1661 ± 297 U · 1−1 · min−1, p <0.05), but failed to affect the corresponding testosterone incremental area. Eight non-obese normal men (Body Mass Index 22.2 ± 0.5) were investigated for comparison. All of them were studied according to the same protocol as the obese group. Short-term fasting increased the GnRH-elicited LH response by 67% in the non-obese group (LH incremental areas 2147 ± 304 vs 3581 ± 256, p <0.01), and the corresponding testosterone response by 180% (testosterone incremental areas 111 ±61 vs 311±49 μg · 1−1 · min−1, p <0.01). These results imply that food deprivation affects the pituitary-testicular axis differently in obese and non-obese men.

The purpose of our study was to determine the effects of severe obesity on the foot mechanics of adult females. Twenty-nine adult females between the ages of 20 and 48 years volunteered as subjects for this investigation. The subjects were separated into a severely obese (O) group (body mass index = 41.14 ± 2.61; N = 16) and a normal weight control group (body mass index = 20.84 ± 0.47; N = 13). A Locam camera (100 Hz) positioned perpendicular to the subjects’ posterior aspect was used to film the rearfoot movement of the subjects during the final 15 sec of a 10 min treadmill walk. The O group had a significantly greater touchdown angle ( P = .05), more total eversion range of motion ( P = .001), and a faster maximum eversion velocity ( P < .001). Moreover, analysis of dynamic foot angles indicated that the O group had significantly ( P = .003) more forefoot abduction. Finally, anthropometric data revealed statistically different ( P < .001) Q angle measurements between the O and control groups. The results of this study suggest that severely obese females have significantly greater rearfoot motion, foot angle, and Q angle values than normal weight females.

Menstrual Dysfunction

Іntroduction. Today, a quarter of the population of economically developed countries has a body weight that is 15% larger than the norm. According to various authors, the timely onset of menarche in women with various forms of obesity and reproductive dysfunction is observed in 31% of cases only. Obesity results in insulin resistance, which in its turn results in hyperinsulinemia. The main reason of the connection of insulin resistance with reproductive function disorders consists in the specific influence of insulin on ovaries. Insulin suppresses apoptosis, binding to receptors of various growth factors that promotes long existence of atresizing follicles. In the pathogenesis of the metabolic syndrome, along with the development of hyperinsulinemia and insulin resistance, a significant role belongs to the imbalance of adipocytokines, one of which is adiponectin. The aim is to analyze metabolic processes in the formation of menstrual dysfunction in adolescent girls with obesity to improve diagnostic methods of menstrual disorders. Material and methods. Clinical and laboratory examination of adolescent girls aged 12-18 years was held, among which 79 had obesity and complaints about menstrual dysfunction (the main group); 31 with normal body weight and regular menstrual cycle (the control group). Research methods: general clinical, biochemical (indicators of lipid and carbohydrate metabolism were determined), instrumental (ultrasound), statistical. Results. It was found that 53.3% of the girls from the main group had the beginning of the first menstruation after 14 years, delayed menstruation from 42 days to 6 days, duration 2.1 ± 0.05 days, which was significantly shorter, the volume of 10.2 ± 0.05; 0.4 points (average 1-2 pads per day) was significantly lower (p <0.05). Ultrasound showed uterine hypoplasia in almost every second girl in the main group - 36 (45.46%). Hyperleptinemia and leptin resistance was found in obesity of the first degree 34.8 ± 1.75, in obesity of the second degree 37.15 ± 2.12, in obesity of the third degree 40.64 ± 2.0. It was 14.35 ng / ml in the control group, p<0,01. Hyperleptinemia in the main group was accompanied by hyperinsulinemia in 26% of cases and insulin resistance. The relationship between low values of adiponectin and elevated body mass index in patients of the main group was established, which was confirmed by the results of correlation analysis (adiponectin & body mass index: ρ = -0.74). Analysis of the results revealed a decrease of A/L level in the main group by 4.3 times. Based on our own results, the A/L and HOMA-AD models can be considered more accurate for determining insulin resistance. Conclusions. 1. Changes of the menstrual cycle in overweight girls were found. The association of adipokines secretion disorders is characterized by hyperleptinemia, leptin resistance, decreased Adiponectin / Leptin index and hypoadiponectinemia, which, in combination with insulin resistance, indicates the participation of adipokines in the genesis of oligomenorrhea. The algorithm of adolescents’ treatment with menstrual dysfunction on the background of obesity must include the calculation of Adiponectin/Leptin and HOMA-AD, which will make it possible to avoid overdiagnosis of insulin resistance.

Introduction: Microbiome status is considered an important factor that contributes to obesity. Investigations have shown that the oral microbiome comprises a vast array of bacterial species that can influence human health. Objective: To determine the association between the presence of the bacterial phyla Firmicutes and Bacteroidetes and the body mass index (BMI) status of normal, overweight and obese subjects in Duhok, Iraq. Additionally, to investigate the composition of oral Firmicutes and Bacteroidetes profiles for individuals with different BMI statuses. Methods: A total of 155 saliva samples were collected from participants in Duhok, Iraq. Bacterial genomic DNA was then extracted from the collected saliva. The presence of Firmicutes and Bacteroidetes phyla was detected via polymerase chain reaction. Results: Firmicutes and Bacteroidetes were detected in 63.2 and 37.4% of the population, respectively. Differences in the carriage rates of oral Firmicutes in overweight (78%) and obese individuals (83%) were statistically significant when compared to normal weight individuals (36%) (P<0.0001). The percentage rates of Bacteroidetes in obese individuals (26.4%) was statistically significant when compared to normal weight individuals (50.8%) (P=0.0078). The Firmicutes/Bacteroidetes ratios (obese=3.1, overweight=2.5 and normal weight=0.7) were higher with increasing BMI. Conclusion: This study provides evidence of the Firmicutes/Bacteroidetes ratio growing with increasing BMI. High rates of Firmicutes could serve a role in the development of obesity. Further studies are required to clarify the exact relationship between oral bacteria and obesity, which could lead to a promising therapeutic method for improving the physical health of humans.

Introduction. A combination of drugs is required for treatment of obese subjects with diabetes, due to multiple pathogenic mechanisms implicated in the development of both diabetes and obesity. Objective. Assessment of the effect of sitagliptin added to insulin glargine and metformin, in obese subjects with type 2 diabetes. Methods. A total of 23 obese subjects on metformin and insulin glargine participated in the study. Titration of insulin glargine during a one-month period preceded the addition of 100 mg of sitagliptin daily. Body mass index, waist circumference, fasting, and prandial glucose were measured monthly, lipids and hemoglobin A1c (HbA1c) every three months, insulin, c-peptide and glucagon at the start and after six months of treatment. Homeostatic models for insulin secretion (HOMA B) and insulin resistance (HOMA IR) were calculated. Results. Participants were 58.65 ?} 7.62 years of age with a body mass index of 35.06 ?} 5.15 kg/m2, waist circumference of 115.04 ?} 15.5 cm, and the duration of diabetes of 4.11 ?} 2.57 years. With the titration of insulin glargine, target fasting glucose levels were not achieved. Waist circumference and body mass index decreased during three months of sitagliptin treatment, thereafter remaining stable. HbA1c decreased significantly after three and six months of therapy. C-peptide increased significantly, while glucagon level fell. HOMA indexes were unchanged. Conclusion. Sitagliptin can improve diabetes control and induce modest weight loss in obese subjects poorly controlled on insulin glargine and metformin. Titration of insulin glargine to optimal fasting glucose values is a prerequisite of success of this combination therapy.
