Your healthcare provider figures out your total cholesterol by looking at a combination of triglycerides, HDL and LDL numbers. If your triglycerides and LDL cholesterol are high, but your HDL is low, you have an increased risk of heart attack and stroke.

Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications.

Triglycerides are a very common kind of fat in your body. They’re in butter and other fats in food. You also make triglycerides from extra calories to use later. But high triglyceride levels can raise your risk of issues like heart attacks and strokes. Exercise and other healthy habits can bring triglyceride levels back to normal.

High levels of triglycerides increase your risk of heart disease and pancreatitis. Eating or drinking too many calories can lead to high triglyceride levels. The good news is that you can take steps to lower triglyceride numbers. Your healthcare provider can offer suggestions for heart-healthy lifestyle changes. If needed, medications can also help.

High triglyceride levels become more of a problem with age. As the risk rises, your healthcare provider might recommend tests more often.

For adults, a normal triglyceride level is below 150 mg/dL. For young people between ages 10 and 19, a normal number for triglycerides is below 90 mg/dL.

Triglycerides are fats from the food we eat. Most of the fats we eat (like butter) are in triglyceride form. Extra calories, alcohol and sugar in your body turn into triglycerides. Your body stores them in fat cells throughout your body like stocking shelves in a pantry. You can use triglycerides later when you need them.

High levels of triglycerides increase your risk of pancreatitis. This severe and painful inflammation of the pancreas can be life-threatening.

Yes, children need cholesterol and triglyceride tests. Providers usually test children between ages 9 and 11 and again during young adulthood (between ages 17 and 21). If a child has a family history of high cholesterol, heart attacks or strokes, their provider may do tests as early as age 2.

Abstract: Power Spectral Density (PSD) is an essential representation of the signal spectrum that depicts the power measurement content versus frequency. PSD is typically used to characterize broadband random signals and has a variety of usages in many fields like physics, engineering, biomedical, etc. This paper proposes a simple and practical method to estimate the PSD based on the Welch algorithm for spectrum monitoring. The proposed method can be easily implemented in most of software-based systems or low-level Field-Programmable Gate Arrays (FPGAs) and yields a smooth overview of the spectrum. The original Welch method utilizes the average of the amplitude squared of the previous Fast Fourier Transform (FFT) samples for better estimation of frequency components and noise reduction. Replacing the simple moving average with a weighted moving average can significantly reduce the complexity of the Welch’s method. In this way, the amount of required Random Access Memory (RAM) is reduced from K (where K is the number of FFT packets in averaging) to one. This new method allows users to adjust the dependency of the PSD on the previous observed FFTs and its smoothness by setting only one feedback parameter without any hardware change. The obtained results show that the algorithm gives a clear spectrum, even in the noisy situation because of the significant Signal to Noise Ratio (SNR) enhancement. The trade-off between spectrum accuracy and time convergence of the modified algorithm is also fully analysed. In addition, a simple solution based on Xilinx Intellectual Property (IP), which converts the proposed method to a practical spectrum analyzer device, is presented. This modified algorithm is validated by comparing it with two standard and reliable spectrum analyzers, Rohde & Schwarz (R&S) and Tektronix RSA600. The modified design can track any signal type as the other spectrum analyzers, and it has better performance in situations where the power of the desired signal is weak or where the signal is mixed with the background noise. It can display the spectrum when the input signal power is 5 dB lower than the visible threshold level of R&S and Tektronix. In both narrowband and wideband scenarios, the new implemented design can still display frequency components 5 dB higher than the noise, while the output spectrum of other analyzers is completely covered by noise.

Pure cholesterol can’t mix with or dissolve in blood. Instead, your liver packages cholesterol with triglycerides and proteins called lipoproteins. The lipoproteins move this fatty mixture to areas throughout your body.

Adults in their 20s, 30s and early 40s may need cholesterol tests every four to six years. If you have diabetes, a family history of high cholesterol or other heart disease risk factors, you may need more frequent tests.

If you have cardiovascular disease or you’re taking medications to lower your cholesterol or triglyceride levels, your healthcare provider or cardiologist might check your triglyceride levels more frequently.

Triglycerides and cholesterol are both fatty substances called lipids. But triglycerides are fats; cholesterol isn’t. Cholesterol is a waxy substance your liver makes. Your body uses it to build cell walls and help your nervous system. It also plays an important role in digestion and hormone production.

Like high cholesterol, high triglycerides rarely cause symptoms. That’s why you need to get routine lipid blood tests to check cholesterol numbers. For the most accurate reading, you should fast eight to 12 hours before a lipid blood test.
