Modeling Performance of Microservices Systems with Growth Theory.

Context: The microservices architectural style is gaining momentum in the IT industry. This style does not guarantee that a target system can continuously meet acceptable performance levels. The ability to study the violations of performance requirements and eventually predict them would help practitioners to tune techniques like dynamic load balancing or horizontal scaling to achieve the resilience property.

Assessment of nocturnal hypertension by ambulatory blood pressure monitoring at the forearm in people with morbid obesity.

Blood pressure (BP) measurement at the forearm (FA) has been proposed as alternative site to upper arm (UA) in people with morbid obesity (MO). We compared nocturnal BP readings simultaneously taken at FA and UA by ambulatory blood pressure monitoring (ABPM). Fourteen individuals with MO and seven normal-weight controls underwent nocturnal ABPM with two devices placed at the UA and contralateral FA, respectively.

Sleeve Gastrectomy Efficacy on Metabolic and Cardiovascular Dysfunction With a Focus on the Role of Comorbidities.

We evaluated the effects of sleeve gastrectomy (SG) on metabolic/cardiovascular parameters according to weight loss, visceral fat area (VFA), and homeostasis model assessment (HOMA)-insulin resistance index; we also assessed the influence of SG on comorbidities (diabetes/hypertension). At baseline and 10 to 12 months after SG, we assessed anthropometric and biochemical parameters, bioimpedentiometry, ultrasonographic VFA, liver steatosis, flow-mediated dilation, and echocardiography in 110 patients with obesity. We found that 23 (21%) patients had diabetes.
