Article Abstract

Advances in chemotherapy and surgery allows the majority of patients to survive cancer diseases. Yet, the price may be a proportion of patients dying of complications due to treatment-induced infectious complications, such as neutropenia. With the aim of decreasing morbidity and mortality related to infectious complications, recombinant human granulocyte colony-stimulating factor (G-CSF), filgrastim, and pegylated filgrastim have been used to reduce time and degree of neutropenia. A biosimilar is a copy of an approved original biologic medicine whose data protection has expired. The patent for filgrastim expired in Europe in 2006 and in the US in 2013. This review analyses the available evidence to be considered in order to design a strategy of use of G-CSF and its biosimilars. The clinical and safety outcomes of biosimilars are well within the range of historically reported data for originator filgrastim. This underscores the clinical effectiveness and safety of biosimilar filgrastim in daily clinical practice. Biosimilars can play an important role by offering the opportunity to reduce costs, thus contributing to the financial sustainability of treatment programs.

We report the case of a 3-month-old infant with methicillin-resistant Staphylococcus aureus (MRSA) necrotizing fasciitis of the neck and chest complicated by bacteremia, pneumonia, and mediastinitis, which required multiple surgical debridements, including median sternotomy. The case is unsual given the patient's age and causative pathogen, and underscores the importance of early diagnosis, timely surgical intervention, and multidisciplinary collaboration to ensure survival.

Unlabelled: Severe acute pancreatitis (SAP) is characterized by systemic inflammation and intestinal barrier dysfunction and is often associated with gut microbiota dysbiosis. Rifaximin, a gut-specific non-absorbable antibiotic, is known to modulate the gut microbiota. Here, we investigated rifaximin's effects and mechanisms in SAP using murine models and a single-center, open-label, randomized controlled trial (Chinese Clinical Trial Registry: ChiCTR2100049794).

Recently, to achieve cure, physicians have been resorting to overuse or misuse of antimicrobials to treat resistant infections, leading to the emergence of further resistant organisms. To overcome this issue, antimicrobial guidelines have been developed. Nevertheless, recently, controversy regarding the effect of adherence to antimicrobial guidelines on patient outcomes has been raised.

Background And Objectives: Increased referrals to skilled nursing facilities (SNFs) from hospitalized people with opioid use disorder (OUD) carry risk for financial, safety, and legal consequences for poor transitions in care. We aimed to better understand the hospital to SNF referral process and identify opportunities to improve transitions and care for people with OUD, an increasing share of whom are older adults.

Research Design And Methods: Participants included administrative, executive leadership, and clinical staff involved in SNF admission decisions across the United States.
