European League Against Rheumatism Sjögren's Syndrome Disease Activity Index and European League Against Rheumatism Sjögren's Syndrome Patient-Reported Index: a complete picture of primary Sjögren's syndrome patients.

Abstract: OBJECTIVE: The European League Against Rheumatism (EULAR) Sjogren's Syndrome (SS) Disease Activity Index (ESSDAI) and the EULAR SS Patient-Reported Index (ESSPRI) were recently developed. We aimed to determine whether patients' symptoms differed between patients with and without systemic involvement and if the disease-specific indices correlated with each other in primary SS. METHODS: Fifteen French centers included 395 primary SS patients in the Assessment of Systemic Signs and Evolution in Sjogren's Syndrome Cohort. At enrollment, physicians completed the ESSDAI, the SS Disease Activity Index (SSDAI), and the Sjogren's Systemic Clinical Activity Index (SCAI), and patients completed the ESSPRI, the Sicca Symptoms Inventory, and the Profile of Fatigue and Discomfort. All scores were compared between patients with and without systemic involvement. Correlations between scores of systemic activity and patients' symptoms were obtained. RESULTS: At enrollment, 120 (30.4%) patients had never experienced systemic complication and 155 (39.2%) patients and 120 (30.4%) patients had, respectively, only past or current systemic manifestations. Past or current systemic patients had higher levels of symptoms, except dryness. The ESSDAI did not correlate with the patient-scored ESSPRI (rho = 0.06, P = 0.30), whereas the SSDAI and the SCAI, which include subjective items, did correlate (rho = 0.28 and 0.25, respectively; P < 0.0001 for both). CONCLUSION: Alterations of common patient-reported outcomes are present in all patients with primary SS, including those with systemic complications. However, patient symptoms and systemic complications are 2 different facets of primary SS. Therefore, the use of both systemic and patients' indices, such as the ESSDAI and ESSPRI, are useful. Since these 2 facets weakly overlap, one should identify which of both components is the main target of the treatment to test, when designing clinical trials in primary SS.

Intelligent accident detection and alert system for emergency medical assistance

Abstract: Road accidents rates are very high nowadays, especially two wheelers. Timely medical aid can help in saving lives. This system aims to alert the nearby medical center about the accident to provide immediate medical aid. The attached accelerometer in the vehicle senses the tilt of the vehicle and the heartbeat sensor on the user's body senses the abnormality of the heartbeat to understand the seriousness of the accident. Thus the systems will make the decision and sends the information to the smartphone, connected to the accelerometer and heartbeat sensor, through Bluetooth. The Android application in the mobile phone will sent text message to the nearest medical center and friends. Application also shares the exact location of the accident that can save the time.

A Four-Port MIMO Antenna Using Concentric Square-Ring Patches Loaded With CSRR for High Isolation

Abstract: A novel four-port multiple-input-multiple-output (MIMO) antenna system is designed using concentric square-ring patch antennas. All four ports are made to resonate at 2.4 GHz ISM band with an overall system dimension of 60×60×1.6 mm 3 . This design uses complementary split-ring resonator (CSRR) loaded on its ground plane for enhanced isolation of - 22 dB between patch antenna elements. CSRR reduces mutual coupling by about 6.5 dB. The antenna operates with a 2:1 VSWR bandwidth of 75 MHz centered at 2.45 GHz. This collocated antenna system satisfies MIMO diversity performance with low envelope correlation between its waveforms. The effectiveness of concentric rings in MIMO design along with proposed isolation enhancement technique is validated using measurements from a prototype.
