“…In the previously study, we used multiscale cross approximately entropy (MCAE) to analyze the PPG pulse amplitudes of bilateral index fingertip (left and right) in the middle-to-old individuals and revealed that the signal from the right finger was more challenging for analysis than the left finger [12]. Therefore, in this present study, we used only PPG pulse amplitude from the right finger.…”

Multiscale entropy (MSE), an estimate of the complexity of physiological signals has been used for assessing diabetes status. This method requires much computation effort. Our study aimed to examine the Poincaré plot, an easier method for computation to differentiate the diabetes status. We selected subjects and divided them into three groups including the nondiabetes (HbA1c ≤ 6.5%, n=22), diabetes with good control (6.5% < HbA1c < 8%, n=23), and diabetes with poor control (HbA1c ≥ 8%, n=17). Poincaré method used consecutive 250 data points of PPG pulse amplitudes from each subject's right index fingertip. This method resulted in SSR, the standard deviation of the original photoplethysmogram (PPG) pulse amplitude (SD1) and the standard deviation of the interval 1 PPG pulse amplitude (SD2) ratio. The SSR in the three groups of non-diabetes, diabetes with good control and diabetes with poor control were 0.50, 0.28, and 0.23, respectively and differed between groups (P < 0.05). Our findings suggested that the Poincaré plot of right-hand PPG pulse amplitude may be convenient to evaluate diabetes status.

“…The authors of the study report that the MSE index for the dominant hand was significantly different between people with poorly and well-controlled diabetes, while the MSE index for the non-dominant hand allowed for the diagnosis of healthy people. In their conclusions, the authors suppose that the MSE of PPG pulse amplitudes can be used to assess microcirculation in people with type 2 diabetes [40].…”

“…As other researchers have pointed out, also other data provided by PPG may be useful in assessing the vitality of the cardiovascular system in diabetics. Gen-Min Lin et al [40] in their research they analyzed Multiscale Entropy (MSE) of PPG pulse amplitudes. They carried out their study on a group of 80 volunteers (36 healthy, 22 with well-controlled diabetes HbA1c <8% and 22 with poorly controlled blood glucose HbA1c ≥ 8%), each performing 1500 resting pulses amplitudes of bilateral index fingers.…”

The development of medicine and the ability to conduct effective therapy in increasingly severe cases create the need to develop new methods of continuous and non-invasive monitoring of the patient's condition. One of the techniques that is widely used in many fields of medicine is photoplethysmography (PPG). The analysis of the latest research indicates that PPG can have much more applications than the measurement of heart rate and arterial saturation of the patient-as shown by the latest research, it can be used in the measurement of many other key parameters. The optimism is the multitude of areas in which PPG monitoring is attempted. There are more and more attempts to use photoplethysmography in diagnosis and evaluation of peripheral vascular diseases, assessment of circulation in diabetic patients and assessment of endothelial function. Authors are focusing on new applications of PPG, its advantages and limitations. Most of them agree that PPG can provide useful knowledge about the patient's condition while being a quick, easy-to-use and cost-effective technique. The following review was created to critically analyze the latest technical developments and uses of PPG in clinical practice. Sources for the following article were found using the PubMed database using keywords such as "photoplethysmography", "oxygen saturation" and "pulse oximeter".

“…Since our previous study showed similar MSE levels of 1500 PPG pulse amplitudes between right and left fingertip in both unaffected individuals and those with diabetes [20], the left fingertip MSE was to be the representative for the analysis. The results of sample entropy between scale factors 1 and 5 were defined as small scales, and those between scale factors 6 and 10 were defined as large scales.…”

Abstract:Multiscale cross-approximate entropy (MC-ApEn) between two different physiological signals could evaluate cardiovascular health in diabetes. Whether MC-ApEn analysis between two similar signals such as photoplethysmographic (PPG) pulse amplitudes of bilateral fingertips can reflect diabetes status is unknown. From a middle-to-old-aged population free of prior cardiovascular disease, we selected the unaffected (no type 2 diabetes, n = 36), the well-controlled diabetes (glycated hemoglobin (HbA1c) <8%, n = 30), and the poorly-controlled diabetes (HbA1c ≥8%, n = 26) groups. MC-ApEn indexes were calculated from simultaneous consecutive 1500 PPG pulse amplitudes signals of bilateral index fingertips. The average of scale factors 1-5 (MC-ApEn SS ) and of scale factors 6-10 (MC-ApEn LS ) were defined as the small-and large-scales MC-ApEn, respectively. The MC-ApEn LS index was highest in the unaffected, followed by the well-controlled diabetes, and then the poorly-controlled diabetes (0.70, 0.62, and 0.53; all paired p-values were <0.05); in contrast, the MC-ApEn SS index did not differ between groups. Our findings suggested that the bilateral fingertips large-scale MC-ApEn LS index of PPG pulse amplitudes might be able to evaluate the glycemic status and detect subtle vascular disease in type 2 diabetes.
