Male infertility is attributed to multiple factors including high levels of sperm DNA fragmentation (SDF). Conventional semen analysis continues to be the gold standard for diagnosis of male factor infertility around the world. However, the limitations of basic semen analysis have prompted the search for complementary assessments of sperm function and integrity. ⋯ While a controlled degree of DNA nicking is required for appropriate DNA compaction, excessive fragmentation of sperm DNA is linked to impaired male fertility potential, decreased fertilization, poor embryo quality, recurrent pregnancy loss, and failure of assisted reproductive technology procedures. However, there is an ongoing debate regarding whether or not to employ SDF as a routine test for male infertility. This review compiles up-to-date information regarding the pathophysiology of SDF, the currently available SDF tests, and the role of SDF tests in natural and assisted conception conditions.

The Rise and Fall of Antithrombin Supplementation in Cardiac Surgery.
Various cohort studies, both retrospective and prospective, showed that low antithrombin levels after cardiac surgery (at the arrival in the intensive care unit and during the next days) were associated with a number of adverse outcomes, including surgical reexploration and thromboembolic events, eventually leading to prolonged stay in the intensive care. Values lower than 58% to 64% of antithrombin activity were indicative of this higher morbidity with good sensitivity and specificity. The scenario generated the hypothesis that low antithrombin levels needed to be corrected by supplementation to improve postoperative outcome. ⋯ A strongly decreased thrombin activity after antithrombin correction may eventually affect the efficiency of the glomerular filtration and cause the deterioration of kidney function, but underlying biological mechanisms remain unclear. In conclusion, low levels of antithrombin activity after cardiac surgery should be considered as a marker of greater severity of the patient's conditions and/or of the complexity of the surgical procedure. There are no indications for antithrombin supplementation in cardiac surgery unless for correcting heparin resistance.

Transforming team culture through curiosity and collaboration: a case study from critical care.
Interprofessional team conflict amplifies division and impedes patient care. Normal differences of opinion escalate to frank conflicts when members respond with indignation or resentment. These behaviors engender a workplace culture that degrades collaborative clinical management and patient safety. ⋯ This exercise supports interprofessional teams to transform dysfunctional interactions by helping team members to develop a mindset of humility and inquiry and to remind themselves about the good intentions in others. To address conflict, we offer a conversational approach grounded in curiosity, respect, and transparency. Ultimately, the most important communication strategy for effective critical care is caring about the perspectives and experiences of other members of the interprofessional team.

Multicenter Study Observational StudyObesity Paradox and Functional Outcomes in Sepsis: A Multicenter Prospective Study.
In Asian populations, the correlation between sepsis outcomes and body mass is unclear. A multicenter, prospective, observational study conducted between September 2019 and December 2020 evaluated obesity's effects on sepsis outcomes in a national cohort. ⋯ Obesity is associated with higher hospital survival and functional outcomes at discharge in Asian patients with sepsis.
