Persistent Menorrhagia and Hemorrhagic Ovarian Cyst in a Patient With Bernard-Soulier Syndrome: A Case Report.

Bernard-Soulier syndrome (BSS) is a rare qualitative condition of platelets wherein deficiency of platelet surface glycoproteins (GP) Ib, IX, and V forms the Ib-IX-V complex, leading to impaired hemostasis. Although it commonly presents as prolonged bleeding in general, women in the reproductive phase report additional complications during menstruation, pregnancy, and childbirth. In women of reproductive age, menorrhagia is a frequent complaint.

A low-cost PPG sensor-based empirical study on healthy aging based on changes in PPG morphology.

Objective: We study the changes in morphology of the photoplethysmography (PPG) signals-acquired from a select group of South Asian origin-through a low-cost PPG sensor, and correlate it with healthy aging which allows us to reliably estimate the vascular age and chronological age of a healthy person as well as the age group he/she belongs to.

Methods: Raw infrared PPG data is collected from the finger-tip of 173 appar- ently healthy subjects, aged 3-61 years, via a non-invasive low- cost MAX30102 PPG sensor. In addition, the following metadata is recorded for each subject: age, gender, height, weight, family history of cardiac disease, smoking history, vitals (heart rate and SpO2).

Improved Pyroelectric Nanogenerator Performance of P(VDF-TrFE)/rGO Thin Film by Optimized rGO Reduction.

The pyroelectric nanogenerator (PyNG) has gained increasing attention due to its capability of converting ambient or waste thermal energy into electrical energy. In recent years, nanocomposite films of poly(vinylidene fluoride-co-trifluoro ethylene) (P(VDF-TrFE)) and nanofillers such as reduced graphene oxide (rGO) have been employed due to their high flexibility, good dielectric properties, and high charge mobility for the application of wearable devices. This work investigated the effect of rGO reduction on pyroelectric nanogenerator performance.

Naringin: Cardioprotective properties and safety profile in diabetes treatment.

Flavonoids derived from plants offer a broad spectrum of therapeutic potential for addressing metabolic syndrome, particularly diabetes mellitus (DM), a prevalent non-communicable disease. Hyperglycemia in DM is a known risk factor for cardiovascular diseases (CVDs), which substantially impact global mortality rates. This review examines the potential effects of naringin, a citrus flavonoid, on both DM and its associated cardiovascular complications, including conditions like diabetic cardiomyopathy.

Analysis of Conflicts of Interest in Studies Related to Robotics in Gastrointestinal and Abdominal Wall Surgery.

Background: Industry payments to physicians represent a potential conflict of interest (COI) and can influence the study conclusions. This study aimed to evaluate the accuracy of the COIs reported in major surgical journals.

Study Design: Studies with at least one American author published between 2016 and 2021 that discussed observational and intervention studies assessing robotic surgery were included in the analysis.
