The Role of the Chronotype in Developing an Excessive Body Weight and Its Complications-A Narrative Review.

The chronotype, the personal predisposition towards morning or evening activities, significantly influences health conditions, sleep, and eating regulations. Individuals with evening chronotypes are often at a higher risk for weight gain due to misalignment between their natural tendencies of functioning and social schedules, resulting in insufficient sleep, disruptions in eating habits, and decreased physical activity levels. Often, impaired glucose tolerance and changes in melatonin, adiponectin, and leptin secretion, along with alterations in the clock gene functions in subjects with evening preferences, may be predisposed to obesity.

[Second reading in breast cancer screening program: State of knowledge and future].

Second reading is an important part of breast cancer organized screening program. Image quality control and detection of non-diagnosed cancer by first reader are the two goals of this process. In France, 6 % of all screening cancer are diagnosed by second reading, actually done on screen film.

Anaerobic osteomyelitis of femoral head with intraosseous, intra-articular, bursal and muscle pneumatosis.

A case is presented of anaerobic osteomyelitis with intraosseous pneumatosis resulting in extension of gas in soft tissue structures and femur in a patient with mitral valve vegetation and bacteremia. The finding of intraosseous pneumatosis and its extension into the hip joint, iliopsoas bursa and subgluteus medius bursa is depicted. Intraosseous pneumatosis is a rare but concerning finding for osteomyelitis in the absence of a penetrating wound, recent surgery, biopsy or fracture.

Concurrent hyperthermia estimation schemes based on extended Kalman filtering and reduced-order modelling.

The success of treating cancerous tissue with heat depends on the temperature elevation, the amount of tissue elevated to that temperature, and the length of time that the tissue temperature is elevated. In clinical situations the temperature of most of the treated tissue volume is unknown, because only a small number of temperature sensors can be inserted into the tissue. A state space model based on a finite difference approximation of the bioheat transfer equation (BHTE) is developed for identification purposes.

Application of multiple modelling to hyperthermia estimation: reducing the effects of model mismatch.

Multiple model estimation is a viable technique for dealing with the spatial perfusion model mismatch associated with hyperthermia dosimetry. Using multiple models, spatial discrimination can be obtained without increasing the number of unknown perfusion zones. Two multiple model estimators based on the extended Kalman filter (EKF) are designed and compared with two EKFs based on single models having greater perfusion zone segmentation.
