Hypertriglyceridemic waist phenotype and nutritional factors: a study with participants of ELSA-Brasil

Diagnosis of Waist Muscle Injury after Exercise Based on High-Frequency Ultrasound Image

The low back is the weight-bearing part of the human trunk and has a complex anatomy with a variety of lesions. The traditional diagnostic imaging methods include X-ray, CT, and magnetic resonance imaging (MRI). With the rapid development of ultrasound diagnostic instruments and diagnostic techniques, high-frequency ultrasonography plays a more important role in the diagnosis of musculoskeletal disorders by virtue of its advantages of being safe, noninvasive, inexpensive, repeatable in a short period of time, and real-time imaging, especially for the display of fine structures of soft tissues, which is superior to CT and MRI. In this paper, the puncture needle was punctured near the intervertebral foramen, anti-inflammatory analgesics were injected under ultrasound surveillance. The anti-inflammatory and analgesic drugs mainly consist of local anesthetics and glucocorticoids. Local anesthetics can immediately block the nociceptive transmission of the diseased nerve, improve muscle tension, and eliminate muscle spasm, and glucocorticoids can effectively eliminate edema and inflammation of the lumbar nerve root and its surrounding tissues. The results showed that high-frequency ultrasound, as a noninvasive imaging examination, can clearly display the structure and spatial hierarchy of the skin, superficial fascia, deep fascia, and muscles of the low back, can provide real-time dynamic bilateral contrast observation, which can be the preferred imaging examination method for soft tissue disorders of the low back, and can compensate with general X-ray, CT, and magnetic resonance imaging to provide richer clinical diagnosis and treatment. It can provide richer imaging information for clinical diagnosis and treatment.

Association Between Lifestyle and Hypertriglyceridemic Waist Phenotype in the PREDIMED-Plus Study

OBJECTIVE

The hypertriglyceridemic waist (HTGW) phenotype is characterized by abdominal obesity and high levels of triglycerides. In a cross-sectional assessment of PREDIMED-Plus trial participants at baseline, HTGW phenotype prevalence was evaluated, associated risk factors were analyzed, and the lifestyle of individuals with metabolic syndrome and HTGW was examined.

METHODS

A total of 6,874 individuals aged 55 to 75 with BMI ≥ 27 and < 40 kg/m² were included and classified by presence (HTGW⁺ ) or absence (HTGW^- ) of HTGW (waist circumference: men ≥ 102 cm, women ≥ 88 cm; fasting plasma triglycerides ≥ 150 mg/dL). Analytical parameters and lifestyle (energy intake and expenditure) were analyzed.

RESULTS

A total of 38.2% of the sample met HTGW⁺ criteria. HTGW⁺ individuals tended to be younger, have a greater degree of obesity, be sedentary, and be tobacco users. They had higher peripheral glucose, total cholesterol, and low-density lipoprotein cholesterol levels; had lower high-density lipoprotein cholesterol levels; and had increased prevalence of type 2 diabetes mellitus. Mediterranean diet (MedDiet) adherence and physical activity were greater in HTGW^- patients. Age, BMI, tobacco use, total energy expenditure, hypertension, type 2 diabetes mellitus, and MedDiet adherence were associated with HTGW⁺ .

CONCLUSIONS

HTGW is a highly prevalent phenotype in this population associated with younger age, higher BMI, tobacco use, and decreased MedDiet adherence. HTGW^- individuals were more physically active with greater total physical activity, and fewer had hypertension.
