[Diagnosis and treatment of perioperative anaemia in elective primary hip and knee arthroplasty : Consensus statement of the "Committee for Perioperative Management" of the Working Group for Endoprosthetics].

Background: Hip and knee arthroplasty remain risk procedures for bleeding complications. The prevalence of preoperative anaemia prior to elective joint replacement is high. There are no standardized guidelines in Germany for the diagnosis and treatment of perioperative anaemia in elective hip and knee arthroplasty.

[Perioperative management of obese patients undergoing elective hip and knee arthroplasty].

Introduction: Obesity is a worldwide growing health crisis, affecting younger and younger age groups and posing new challenges for arthroplasty. Due to increased complication rates in this population, many authors are of the opinion that in patients with a body mass index (BMI) of over 40, the problems outweigh the benefits of surgery and that surgery should be postponed until significant weight reduction has been achieved.

Materials And Methods: A systematic review of electronic databases (PubMed, Embase, Web of Science and the Cochrane Library) was performed.

Chronic intermittent fasting impairs β cell maturation and function in adolescent mice.

Intermittent fasting (IF) is a nutritional lifestyle intervention with broad metabolic benefits, but whether the impact of IF depends on the individual's age is unclear. Here, we investigated the effects of IF on systemic metabolism and β cell function in old, middle-aged, and young mice. Short-term IF improves glucose homeostasis across all age groups without altering islet function and morphology.

Revealing the reaction path of UVC bond rupture in cyclic disulfides with ultrafast x-ray scattering.

Disulfide bonds are ubiquitous molecular motifs that influence the tertiary structure and biological functions of many proteins. Yet, it is well known that the disulfide bond is photolabile when exposed to ultraviolet C (UVC) radiation. The deep-UV-induced S─S bond fragmentation kinetics on very fast timescales are especially pivotal to fully understand the photostability and photodamage repair mechanisms in proteins.

[Diabetes mellitus and total joint arthroplasty-What should be considered?].

Diabetes mellitus (DM) is on the rise in the population. Approximately 10% of adults suffer from DM. Over two-thirds of patients are over 60 years old, and thus it particularly affects patients who have to undergo total joint arthroplasty.
