The interrelationship between impaired glucose tolerance and other risk factors for cardiovascular disease: is it a predictor for cardiovascular disease?

The Safety of Large-Amount Liposuction: A Retrospective Analysis of 28 Cases

Aim

Our study aims to assess the safety of large amounts of liposuction in a new light.

Materials and Methods

This is a retrospective review of patients who underwent large-volume liposuction from August 2020 to April 2021. Patient demographics, liposuction areas, the amount of infiltrate and aspirate, the surface area of liposuction areas, anesthesia duration, pain score after surgery, preoperative and 4-h postoperative hemoglobin, and basic metabolic panel (sodium, potassium, creatinine, urea) were measured.

Results

Out of the 28 patients, 26 (92.85%) were females. The mean age was 37.1 years old. The mean preoperative hemoglobin was 13.73 g/dL. The average anesthesia time was 220.39 min. The average amount of liposuction infiltrated was 7.55 L, and the average amount of liposuction aspirate was 6.83 L. The mean hemoglobin 4 h postoperatively was 13.7 g/dL.

Conclusions

With proper patient selection and a comprehensive physical exam with preoperative blood workup performed in an accredited facility with a highly experienced plastic surgeon and anesthesiologist, mega liposuction can be safely performed as a day surgery procedure.

Safety and benefits of large-volume liposuction: a single center experience

Background

Liposuction is a surgical technique to remove excess fat deposits from specific areas of the body. Purpose of this study is to determine how far large volume liposuction is safe and effective.

Methodology

From July 2003 to December 2005, 60 female patients had liposuction of different areas of the body as waist, hips, buttocks, thighs, and knees. Their mean age was 30.6 ± 15.4 years old. A standard liposuction technique was done by using a tumescent infiltration formula. The average amount of infusate was 3000 cc, with an average aspirate amount of 6000 cc. Pre-operative anthropometric measurements as weight, height, body mass index, areas to be liposuctioned in addition to pre-operative hematological investigations as complete blood picture, blood sugar, liver function tests, blood urea, serum creatinine, and serum cholesterol were done.

Results

The results were evaluated with preoperative and postoperative photographs. Postoperative anthropometric measurements and hematological investigations were done at 6^th week, and 4^th month after surgery. The rate of complications was low and relatively minor in nature. No major complications were presented. Minor complications have occurred as skin irregularities (20%), Seroma (15%), Garment pressure sore (10%), Cutaneous hyper-pigmentation (5%).

Conclusion

Large-volume liposuction can be performed safely and it can produce desirable morphological and hematological changes.

Subscapular skinfold thickness distinguishes between transient and persistent impaired glucose tolerance: Study on Lifestyle-Intervention and Impaired Glucose Tolerance Maastricht (SLIM)

AIMS

To assess whether adding anthropometric measurements to an oral glucose tolerance test (OGTT) can help to distinguish between transient and persistent impaired glucose tolerance (IGT).

METHODS

From the SLIM project (Study on Lifestyle-Intervention and IGT Maastricht), a study designed to evaluate whether diet and physical activity intervention can improve glucose tolerance in subjects at risk for diabetes, 108 subjects with IGT underwent a repeated OGTT 2-4 months after the initial OGTT. Following the second test, subjects were classified as transient IGT, or persistent IGT. Anthropometric measurements, including body mass index, waist and hip circumference, sagittal and transverse abdominal diameters and skinfold thickness measurements, were done during the second OGTT.

RESULTS

Persistent IGT was diagnosed in 47 subjects (44%), transient IGT in 40 (37%), impaired fasting glucose in eight subjects (7%), and diabetes in 13 cases (12%). Two-hour blood glucose levels at the initial OGTT and subscapular skinfold thickness were significantly higher in subjects with persistent IGT (2-h blood glucose 9.8+/-0.1 mmol/l vs. 10.2+/-0.1 mmol/l for transient IGT and persistent IGT, respectively; subscapular skinfold thickness 25.4+/-1.4 mm vs. 29.8+/-1.2 mm for transient IGT and persistent IGT, respectively). After adjustment for age, sex and family history of diabetes mellitus, logistic regression indicated that 2-h blood glucose level during the initial OGTT represented the strongest predictor of persistent IGT (P<0.02), followed by subscapular skinfold thickness (P<0.05). After adjustment for 2-h blood glucose levels during the first OGTT, subscapular skinfold thickness remained significantly associated with persistent IGT (odds ratio 1.84; P<0.05).

CONCLUSIONS

In addition to the 2-h blood glucose level, subscapular skinfold thickness was the best predictor of persistent IGT, suggesting that adding simple anthropometric measures to oral glucose tolerance testing may improve the distinction between persistent and transient glucose intolerance.

Improvements in cardiovascular risk profile with large-volume liposuction: a pilot study

In this study, the authors investigated the physiologic effects of the altered body composition that results from surgical removal of large amounts of subcutaneous adipose tissue. Fourteen women with body mass indexes of greater than > 27 kg/m2 underwent measurements of fasting plasma insulin, triglycerides, cholesterol, body composition by dual-energy x-ray absorptiometry (DXA), resting energy expenditure, and blood pressure before and after undergoing large-volume ultrasound-assisted liposuction. There were no significant intraoperative complications. Body weight had decreased by 5.1 kg (p < 0.0001) by 6 weeks after liposuction, with an additional 1.3-kg weight loss (p < 0.05) observed between 6 weeks and 4 months after surgery, for a total weight loss of 6.5 kg (p < 0.00006). Body mass index decreased from (mean +/- SEM) 28.8 +/- 2.3 to 26.8 +/- 1.5 kg/m2 (p < 0.0001). This change in body weight was primarily the result of decreases in body fat mass: as assessed by DXA, lean body mass did not change (43.8 +/- 3.1 kg to 43.4 +/- 3.6 kg, p = 0.80), whereas DXA total body fat mass decreased from 35.7 +/- 6.3 to 30.1 +/- 6.5 kg (p < 0.0001). There were significant decreases in fasting plasma insulin levels (14.9 +/- 6.5 mIU/ml before liposuction versus 7.2 +/- 3.2 mIU/ml 4 months after liposuction, p < 0.007), and systolic blood pressure (132.1 +/- 7.2 versus 120.5 +/- 7.8 mmHg, p < 0.0002). Total cholesterol, high-density lipoprotein cholesterol, plasma triglycerides, and resting energy expenditure values were not significantly altered after liposuction. In conclusion, over a 4-month period, large-volume liposuction decreased weight, body fat mass, systolic blood pressure, and fasting insulin levels without detrimental effects on lean body mass, bone mass, resting energy expenditure, or lipid profiles. Should these improvements be maintained over time, liposuction may prove to be a valuable tool for reducing the comorbid conditions associated with obesity.

Postchallenge hyperglycemia and mortality in a national sample of U.S. adults

OBJECTIVE

Although postchallenge hyperglycemia is a well-established feature of type 2 diabetes, its association with risk of mortality is uncertain. Therefore, the aim of this study was to assess the independent association of fasting and 2-h glucose levels with all-cause and cardiovascular disease (CVD) mortality.

RESEARCH DESIGN AND METHODS

We analyzed data from the Second National Health and Nutrition Examination Survey (NHANES II) Mortality Study, a prospective cohort study of U.S. adults examined in the NHANES II, and focused on the 3,092 adults aged 30-74 years who underwent an oral glucose tolerance test at baseline (1976-1980). Deaths were identified from U.S. national mortality files from 1976 to 1992. To account for the complex survey design, we used SUDAAN statistical software for weighted analysis.

RESULTS

Compared with their normoglycemic counterparts (fasting glucose [FG] < 7.0 and 2-h glucose < 7.8 mmol/l), adults with fasting and postchallenge hyperglycemia (FG > or =7.0 and 2-h glucose > or =11.1 mmol/l) had a twofold higher risk of death after 16 years of follow-up (age- and sex-adjusted relative hazard [RH] 2.1, 95% CI 1.4-3.2). However, adults with isolated postchallenge hyperglycemia (FG < 7.0 and 2-h glucose > or =11.1 mmol/l) were also at higher risk of death (1.6, 1.0-2.6). In proportional hazards analysis, FG (fully adjusted RH 1.10 per 1 SD; 95% CI 1.01, 1.22) and 2-h glucose (1.14, 1.00-1.29) showed nearly identical predictive value for mortality. Similar trends were observed for CVD mortality.

CONCLUSIONS

These results suggest that postchallenge hyperglycemia is associated with increased risk of all-cause and CVD mortality independently of other CVD risk factors.

Functional ability of elderly persons with diabetes or impaired glucose tolerance

OBJECTIVE

To describe functional ability of elderly persons with diabetes (DM) or impaired glucose tolerance (IGT) and to describe associations between functional ability and glucose tolerance.

DESIGN

A survey among an unselected non-institutionalized elderly population. Diabetes was assessed on the basis of self-reports and 2-h oral glucose tolerance tests. Functional ability was assessed in interviews by four items on mobility, five items on activities of daily living, and four items on instrumental activities of daily living.

SETTING

Three municipalities in northern Finland.

SUBJECTS

All non-institutionalized persons aged 70 years or over (n = 483; 180 men). The participation rate was 79%.

MAIN OUTCOME MEASURES

Mobility, activities of daily living, and instrumental activities of daily living.

RESULTS

The functional ability of the diabetic persons was poorer than that of the non-diabetic persons. The subjects with IGT also graded their functional ability as somewhat poorer than the non-diabetic subjects. When adjusted for age, gender, history of cardiovascular disease or stroke, these associations became weaker.

CONCLUSIONS

Impaired functional ability is associated not only with diabetes but also with IGT in the elderly, but, in addition to age, cardio- and/or cerebrovascular disease is the best predictor of decreased functional ability in the elderly.
