<p>Analysis of brain signals and their properties provides valuable information regarding the underlying neural deficiencies and enables the diagnosis of attention bias related to public speaking anxiety (PSA). Although 25% people around the world suffer from PSA, currently, there exists a lack of standard assessment in diagnosing the severity of attention bias in individuals with PSA. This study aims to distinguish behavioral and neural abnormalities related to attentional bias during PSA by comparing reaction time (RT) and event-related potential (ERP) correlates of high (H) PSA and low (L) PSA individuals. 12 individuals suffering from HPSA and 12 individuals with LPSA participated in the modified emotional Stroop experiment. Electroencephalography (EEG) was recorded with the low cost, 14-channel Emotiv Epoc+. RT showed slower responses, linked to attentional deficits in HPSA individuals. ERP results revealed the P200 emotional Stroop biomarker, found to be linked to attentional bias in HPSA, but not in LPSA individuals. These results revealed significant RT and P200 ERP abnormalities related to attentional bias in HPSA individuals using the low-cost Emotiv Epoc+.</p>

BACKGROUNDIndia is the second most populous country in the world after China. In an effort to stabilize the population, National Family Welfare Program was launched in 1951. There has been an increase in contraceptive prevalence and a reduction in total fertility rate since then. For better results, contraceptive use should start right from the post partum period. This also significantly reduces maternal and infant mortality rates.

Introduction: Abnormal Uterine Bleeding (AUB) is defined as any deviation from the normal menstrual cycle that is abnormal in regularity, duration, volume and frequency. AUB may be accompanied by pain and discomfort which presents a substantial burden on patient’s health, quality of life, society and healthcare system. There is also an increased incidence of associated co-morbidities like thyroid disease, diabetes and hypertension in AUB cases. Aim: To estimate the prevalence of AUB according to the PALM-COEIN classification and its associated risk factors in the perimenopausal age group. Materials and Methods: This retrospective study was conducted in the Gynecology Department of Malabar Medical College, Kozhikode, Kerela, India. The data was collected from the medical records and computerised system of the hospital for a period of one year from January 2021 to December 2021. A total of 225 patients in the perimenopausal age group (40 years and above) attending Gynecology Outpatient Department (OPD) and admitted with complaints of AUB was included. Patient’s information such as age, menstrual history, obstetric history, medical and surgical history, laboratory tests, imaging findings, endometrial biopsy results was obtained and analysed. Data was entered in Microsoft excel excel and analysed by using Statistical Package for the Social Science (SPSS) version 24.0. Results: The total number of patients attending the gynecology outpatient department during the study period was 11765. The total number of AUB cases during the study period were 2154, so the prevalence for AUB was 18.3%. For the assosciated risk factors, 255 patients were considered, where maximum number of patients 103 (45.3%) were in the age group of 45- 49 years. Structural causes accounts for 175 (77.6%) cases. Hypertension was the most common risk factor associated with AUB 68 (30.2%), followed by diabetes 32 (14.2%) and thyroid disorders 15 (6.6%). Conclusion: The prevalence of AUB was 18.3% in present study. Abnormal Uterine Bleeding - Ovulatory dysfunction and Abnormal Uterine Bleeding- Endometrial had statistically significant association with thyroid disease.

A technology of wireless body area network (WBAN) was invented in order to enhance the quality of healthcare management as well as to determine faster disease prevention. However, to obtain the real-time data of images and videos from inside the human body, an implantable device is required. Currently, the Medical Implant Communication System (MICS) is used, but, this system has limited data rate which is a narrow-band of 402 – 405 MHz. Thus, this study on Ultra Wideband (UWB) for implanted device is conducted as UWB offers a wide transmission bandwidth as well as high data rate. Knowledge of radio wave propagation behaviour inside human body is needed to perform the implantation. Past researches related to this topic are limited and those conducted focused only on the human torso. This paper aims to provide a better understanding on the characteristics of radio wave propagation inside the human body by using an implantable device at UWB frequency. It is also hoped that this study could be used as reference for future research on this subject.
