Introduction: Negative-pressure wound therapy is a therapeutic technique that uses a vacuum dressing in order to promote healing in acute or chronic wounds. The continued vacuum draws out fluid from the wound and increases blood flow to the area. The aim of this study was to establish the effectiveness of negative pressure therapy increasing this way the chances of rehabilitation after knee prosthesis infections.
Material And Method: 11 patients with septic complications after total knee joint replacement were involved into this study, from the Department of Orthopaedic and Traumatology of Bucharest Emergency University Hospital. In all of the cases negative pressure wound treatment was applied. The surgical approach was chosen according to the surgeon's preferences or along the pre-existing surgical approach.
Results And Discussions: Time from the knee arthroplasty to the clinical and biological manifestation of septic complications was about 35 days with limits between 21 and 42 days. In most cases we managed to keep the implant, the outcome obviously being conditioned by using the negative pressure. Knee infections are still a hazardous problem in orthopedic surgery. Negative-pressure system increased the granulation tissue formation and the local blood flow and enhanced the bacterial clearance function.
Conclusions: The clinical outcome in our cases indicates that the Negative-Pressure Wound Therapy can be a valuable contribution to the treatment of knee joint infections.

Associations between skeletal muscle mass and elevated blood pressure are independent of body fat: a cross-sectional study in young adult women of African ancestry.

Although research on the relationship between lean body mass and blood pressure (BP) has been inconsistent, most studies reported that measures of lean body mass are associated with a higher risk of hypertension. We explored relationships between body composition (fat and skeletal muscle mass) and BP in 1162 young adult African women. DXA-derived measures of whole body, central and arm fat mass were associated with higher systolic and diastolic BP, while leg fat percentage was associated with lower systolic and diastolic BP.

Spread of lung cancer to the leptomeninges is rare and difficult to treat. Standard therapy comprises CNS-penetrant targeted agents with or without intrathecal chemotherapy. We performed a retrospective analysis of 16 patients with advanced NSCLC and leptomeningeal disease treated with intrathecal pemetrexed 50 mg.

Necrotizing soft tissue infections (NTSIs) represent a concept of necrotizing infections involving the skin, subcutaneous tissue, fascia, and muscle, and it is a potentially fatal disease. Early exploratory incision is strongly recommended for both the diagnosis and treatment of necrotizing soft tissue infections. Treatment of necrotizing soft tissue infections requires the administration of appropriate antimicrobial agents and adequate surgical debridement.

Objectives: Identifying patients in the emergency department (ED) at higher risk for in-hospital mortality can inform shared decision making and goals-of-care discussions. Electronic health record systems allow for integrated multivariable logistic regression (LR) modeling, which can provide early predictions of mortality risk in time for crucial decision making during a patient's initial care. Many commonly used LR models require blood gas analysis values, which are not frequently obtained in the ED.

Purpose: Management of the elderly patients presenting with open lower limb fractures is challenging due to physiological changes and pre-existing co-morbidities. The aim of this study was to assess the compliance with the British Orthopaedic Association's Standards for Trauma Number 4 (BOAST 4) guidelines in this patient group.
Methods: The study included a retrospective analysis of all the patients aged > 65 years old admitted with open lower limb fracture between 2017 and 2019 to a major trauma centre (MTC) in East of England.
