Broadening Perspectives of Artificial Intelligence in Echocardiography.

Echocardiography frequently serves as the first-line treatment of diagnostic imaging for several pathological entities in cardiology. Artificial intelligence (AI) has been growing substantially in information technology and various commercial industries. Machine learning (ML), a branch of AI, has been shown to expand the capabilities and potential of echocardiography. ML algorithms expand the field of echocardiography by automated assessment of the ejection fraction and left ventricular function, integrating novel approaches such as speckle tracking or tissue Doppler echocardiography or vector flow mapping, improved phenotyping, distinguishing between cardiac conditions, and incorporating information from mobile health and genomics. In this review article, we assess the impact of AI and ML in echocardiography.

Echocardiography is the most common test in cardiovascular imaging and helps diagnose multiple different diseases. Machine learning, a branch of artificial intelligence (AI), will reduce the workload for medical professionals and help improve clinical workflows. It can rapidly calculate a lot of important cardiac parameters such as the ejection fraction or important metrics during different phases of the cardiac cycle. Machine learning algorithms can include new technology in echocardiography such as speckle tracking, tissue Doppler echocardiography, vector flow mapping, and other approaches in a user-friendly manner. Furthermore, it can help find new subtypes of existing diseases in cardiology. In this review article, we look at the current role of machine learning and AI in the field of echocardiography.

Unraveling the Link Between Fibromuscular Dysplasia and Acute Coronary Syndrome: A Comprehensive Case Report and Analysis.

We present a rare case of fibromuscular dysplasia (FMD) manifesting in the mid to distal segment of the left anterior descending (LAD) artery, which led to the development of acute coronary syndrome (ACS) in our patient, highlighting the severe consequences of this vascular disorder. During the investigation of the patient's clinical symptoms, an unexpected incidental finding emerged, indicating bilateral FMD involvement of the renal arteries. This serendipitous discovery underscores the importance of comprehensive evaluation and thorough exploration when managing patients with FMD. We aim to shed light on the intriguing nature of FMD and emphasize the need for vigilant assessment to identify potential multi-vessel abnormalities, even beyond the primary affected site. We also aim to highlight the coronary artery manifestation of FMD as ACS and discuss its medical management.

Effect of nebivolol beneficial on lipid profile and glycemic control in comparison with Atenolol in patients with type 2 DM with concomitant hypertension.

Blood pressure control in hypertensive patients with metabolic abnormalities is challenging because many antihypertensive drugs adversely affect metabolism. Nebivolol a 3rd generation vasodilatory ß-blocker offer neutral or beneficial effects on insulin sensitivity and lipid metabolism. The purpose of this study was to evaluate the effect of nebivolol and atenolol on glycemic control and lipid profile in type 2 diabetes patients with concomitant hypertension. We conducted a 12 weeks double blind randomized clinical trial at Sheik Zayed Hospital Rahim Yar Khan. Patients were randomly divided in to two groups. Patients in group were given tablet nebivolol 5-10mg while patients in group B were given tablet Atenolol 25-50mg/daily for a period of 12 weeks. Pre and post data were analyzed by SPSS 20. After 12 weeks, Both drugs lowered blood pressure significantly i.e. nebivolol (SBP from152±12 to130±14 with p=0.004, DBP from 95±12 to78±8.5 with p=0.002) Atenolol (SBP from148±16.5 to 128±15.5 with p=0.006, DBP from 90±10.5 to 82±12 with p=0.003).Similarly both Nebivolol and Atenolol did not any significant effect on glycemic control and lipid profile at 12 week with in groups. However when comparison was done between two groups, Nebivolol significantly reduced blood sugar (p=0.001), HbA1c (p=0.0032), total Cholesterol (p=0.002), triglycerides (p=0.012), LDL-Cholesterol (p=0.007) and HDL-Cholesterol (p=0.001) as compared to atenolol. In comparison with atenolol, Nebivolol has a beneficial effect on glycemic control and serum lipid profile.

Sodium-Glucose Cotransporter-2 (SGLT-2) Attenuates Serum Uric Acid (SUA) Level in Patients with Type 2 Diabetes.

BACKGROUND: Hyperuricemia has a strong association with diabetes mellitus. Hyperuricemia can lead to cardiovascular and renal complications in patients with diabetes. The goal of this study was to compare the effect of sodium-glucose cotransporter-2 (SGLT-2) inhibitors dapagliflozin and empagliflozin on serum uric acid (SUA) levels in patients with type 2 diabetes against traditional oral antihyperglycemic drugs (OADs). METHODS: In this double-blind randomized controlled trial, 70 patients with type 2 diabetes and elevated SUA levels were assigned to two treatment groups. Patients in group A received SGLT-2 inhibitors tablet dapagliflozin 5 mg to 10 mg and empagliflozin 10 mg to 25 mg. Group B patients received OADs such as glimepiride, metformin, sitagliptin, gliclazide, and glibenclamide as monotherapy or combination therapy. The changes in SUA level were primary end points while changes in body weight and body mass index (BMI) from baseline to end point were secondary end points. RESULTS: After four weeks of treatment, we noted a significant reduction of mean SUA levels in the SGLT-2 inhibitor group from 7.5 ± 2.5 to 6.3 ± 0.8 mg/dl versus comparator group from 7.1 ± 1.8 to 6.8 ± 2.2 mg/dl (p = 0.001). Mean body weight was significantly reduced in the SGLT-2 group from 82 ± 10.4 to 78 ± 12.5 kg versus comparator group from 78 ± 13.2 to 79.2 ± 9.7 kg (p = 0.001). Similarly, the mean BMI of patients in the SGLT-2 group was significantly reduced from 25.7 ± 3.2 to 24.2 ± 3.2 kg/m2 versus comparator group from 27.5 ± 4.2 to 28 ± 3.6 kg/m2 (p = 0.002). CONCLUSION: SGLT-2 inhibitors have a strong potential to decrease SUA levels in patients with type 2 diabetes.

Comparison of Efficacy and Safety Profile of Sodium-Glucose Cotransporter-2 Inhibitors as Add-On Therapy in Patients With Type 2 Diabetes.

Background Type 2 diabetes is a chronic metabolic disorder that is escalating at an alarming rate worldwide. Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are recent oral antihyperglycemic drugs (OADs) with a unique mechanism of action. Objectives This study aimed compared the efficacy and safety profiles of two SGLT-2 inhibitors, empagliflozin and dapagliflozin, in patients with type 2 diabetes as add-on therapy to traditional first-line OADs. Methods We conducted a randomized controlled trial comparing empagliflozin and dapagliflozin in patients with type 2 diabetes. Patients were included in the study if they had type 2 diabetes with inadequate glycemic control, defined as glycated hemoglobin (HbA1c) of 7.5% to 11.0%, treated with conventional first-line OADs. Study participants were randomly assigned into two groups. Group A patients received oral empagliflozin, 10 to 25 mg, and Group B patients received oral dapagliflozin, 5 to 10 mg, for 12 weeks. The primary endpoint was the efficacy profile for each SGLT-2 agent in terms of body weight changes, body mass index (BMI), fasting blood glucose (FBG), and HbA1c. The secondary endpoint was to determine the safety and tolerability profiles of each SGLT-2 agent. Results After 12 weeks of treatment, the mean body weight was reduced significantly in both groups from baseline (empagliflozin: -3.2 kg ± 5.5 kg, p = 0.003; dapagliflozin -2.1 kg ± 4.6 kg, p = 0.008). However, the mean body weight reduction between groups was not statistically significant (p = 0.078). BMI was significantly reduced in both groups (empagliflozin from 28.5 ± 4.9 kg/m2 to 25.8 ± 5.2 kg/m2, p = 0.002; dapagliflozin from 29 ± 5.2 kg/m2 to 27.7 ± 4.8 kg/m2, p = 0.003). However, the patients who received empagliflozin experienced a significantly greater reduction in BMI than patients who received dapagliflozin (p = 0.007). The mean FBG was also reduced in both study groups (empagliflozin: -88.5 mg/dL ± 39.7 mg/dl, p = 0.003; dapagliflozin: -59.8 mg/dL ± 48.5 mg/dL; p = 0.007). However, the patients who received empagliflozin experienced a significantly greater reduction in mean FBG than patients who received dapagliflozin (p = 0.001). HbA1c was also significantly reduced in both groups (empagliflozin: -2.1% ± 1.1%, p = 0.002; dapagliflozin: -1.4% ± 0.9%; p = 0.004). However, patients who received empagliflozin experienced a significantly greater reduction in HbA1c than patients who received dapagliflozin (p = 0.001). The tolerability profiles of both SGLT-2 agents were quite good, and no major adverse effects were reported in the study groups. Urinary infection occurred more often in patients who received dapagliflozin (9.3%) than in patients who received empagliflozin (4.5%; p = 0.002). Patients in the dapagliflozin group also had a higher incidence of genital infections (7.3%) than those in the empagliflozin group (3.8%; p = 0.001). Conclusion Both empagliflozin and dapagliflozin demonstrated excellent efficacy and safety profiles in our study. These agents should be considered as add-on therapy in patients with type 2 diabetes taking conventional first-line OADs.

Monolithic integration of nitride light emitting diodes and photodetectors for bi-directional optical communication.

Design and fabrication of monolithically integrated III-nitride visible light-emitting-diodes (LEDs) and ultraviolet Schottky barrier-photodetectors (SB-PDs) have been proposed and demonstrated. Responsivity up to 0.2 AW(-1) at 365 nm for GaN SB-PDs has been achieved. It is shown that those UV SB-PDs were capable of sensitive UV light detection down to 7.16×10(-4) W/cm2 at 365 nm, whereas simultaneous operation of on-chip blue LEDs has produced negligible crosstalk at practical illumination brightness. Monolithically integrated LEDs and SB-PDs can function as transmitters to emit visible light signals, and as receivers to analyze incoming UV signals, respectively; this offers the potential of using such devices for bi-directional optical wireless communication applications.
