BACKGROUND: In severe malaria, intravenous artesunate may cause delayed haemolytic anaemia but there has been little evaluation of the propensity of oral artemisinin-based combination treatments (ACTs) to cause late-appearing anaemia. METHODS: The frequency of anaemia (haematocrit <30%), and temporal changes in haematocrit were evaluated in 1,191 malarious children following ACTs. "Haematocrit conservation" was evaluated by using the fall in haematocrit/1,000 asexual parasites cleared from the peripheral blood (FIH/1,000 asexual parasites cpb), and the ratio of the average haematocrit (on the first 3 days of starting treatment):total parasitaemia cleared...

The presence of chronic inflammation in the colonic mucosa leads to an increased risk of cancer. Among proteins involved in the regulation of mucosal inflammation and that may contribute both to structural damage of the intestinal mucosa and to intestinal carcinogenesis, there are myeloperoxidase (MPO) and vanins. The infiltration of colonic mucosa by neutrophils may promote carcinogenesis through MPO, a key enzyme contained in the lysosomes of neutrophils that regulates local inflammation and the generation of reactive oxygen species (ROS) and mutagenic species...

Surgical site infection (SSI) contributes significantly to surgical morbidity. Patient factors and operative factors contribute to the risk of development of SSI. This review focuses on understanding operative characteristics that are associated with an increased risk of SSI. Much attention has been given to protocol care to reduce SSI, such as hair removal, skin preparation, and pre-operative antibiotic agents. Even with this, the appropriate antibiotic and re-dosing regimens often remain a challenge. Other operative factors such as blood loss/transfusion, emergency/urgent cases, duration of the operation, type of anesthesia, and resident involvement are also potentially modifiable to reduce the risk of SSI...

Ischemic heart disease (IHD), or acute coronary syndrome (ACS), is one of the leading causes of death in the United States. IHD is characterized by reduced blood supply to the heart, resulting in the loss of oxygen to and the ensuing necrosis of the heart muscle. The MI model has gained popularity for its use as a short-term ischemia-reperfusion model and a long-term permanent ligation model. Below, we describe a reliable method for the permanent ligation of the LAD. With mouse genetic engineering technology becoming more advanced, and with an increasing availability of quality murine surgical instruments, the mouse has become a popular model for MI surgeries...

REVIEW
Clay Cothren Burlew
Patients with haemodynamic instability due to pelvic fracture-related bleeding can have life-threatening haemorrhage. Management options for haemorrhage control in complex pelvic fractures include bony stabilization, angioembolization, and preperitoneal pelvic packing (PPP). The indications for PPP as well as the operative technique and outcomes will be described in this review. PPP directly addresses the bony and venous bleeding of complex pelvic fractures, which results in the majority of blood loss in exsanguinating patients...

Patients with type 2 diabetes mellitus (T2DM) exhibit an increased risk of cardiovascular (CV) events. Treatment of these patients with traditional as well as newer glucose-lowering drugs has not demonstrated superiority in CV outcomes compared to placebo, despite effective control of diabetes. However, the recently FDA-approved sodium-glucose cotransporter 2 (SGLT2) inhibitors for the treatment of T2DM have demonstrated promising CV-protecting and blood pressure-lowering effects in addition to their effectiveness in glucose lowering, making them a novel class of drugs for the treatment of T2DM...

PURPOSE: Uveitic inflammatory injury can cause irreversible visual loss; however, no single animal model recapitulates all the characteristics of human uveitis. Ultraviolet radiation (UVR) is one of the risk factors for uveitis, but the role of UVR in the pathogenesis of uveitic injury is unclear. The aim of this study was to elucidate whether UVB promotes the initiation of, and subsequently contributes to, uveitic inflammatory injury. METHODS: Mice were assigned to either a blank control group or one of three UVB treatment groups: no protection, protection with Nelfilcon A contact lens (Food and Drug Administration [FDA] class II, about 46...

Diabetes is the leading cause of end stage renal disease, resulting in a significant health care burden and loss of economic productivity by affected individuals. As current therapies for progression of diabetic nephropathy (DN) are only moderately successful, identification of underlying mechanisms of disease is essential in order to develop more effective therapies. We showed previously that inhibition of arginase using S-(2-boronoethyl)-L-cysteine (BEC) or genetic deficiency of the arginase-2 isozyme was protective against key features of nephropathy in diabetic mouse models...

Deoxynivalenol (DON) is one of the most prevalent mycotoxins in Europe. Pigs are an animal species that is most susceptible to this mycotoxin. Deoxynivalenol causes significant losses in pig production by lowering feed intake, decreasing daily weight gains, disrupting immune responses, and increasing susceptibility to diseases. The aim of this experiment was to determine the influence of feed contaminated with DON at concentrations insignificantly higher than recommended by the European Commission (900 µg/kg)...

BACKGROUND: Use of dilute epinephrine tumescent solution in breast reduction surgery has been shown to significantly decrease operative blood loss without increasing perioperative complications. Lidocaine is commonly added to epinephrine to decrease postoperative pain. Evidence supporting this practice, however, is limited, and lidocaine toxicity has been reported. METHODS: With institutional review board approval, patients undergoing bilateral breast reduction surgery were assigned to receive either tumescent saline solution with epinephrine (1:1 million) (group 1), or tumescent saline solution with epinephrine (1:1 million) and lidocaine (0...

BACKGROUND: For total knee arthroplasty (TKA), the tourniquet is routinely employed for better visualization, less blood loss, and easier cementation. However, the time to release tourniquet remains controversial. Therefore, we performed current meta-analysis to assess whether releasing tourniquet before wound closure is more effective in reducing blood loss than releasing tourniquet after wound closure in TKA without an increased risk of complications. METHODS: To conduct this meta-analysis, we searched Medline, Embase, Web of science, and the Cochrane library up to November 2016, for randomized controlled trials comparing tourniquet releasing before and after wound closure in TKA...

BACKGROUND: Total joint arthroplasty (TJA) usually results in postoperative bleeding. Some randomized controlled trials (RCTs) and nonrandomized controlled trials (non-RCTs) have been performed to evaluate the effects of epinephrine on postoperative bleeding after TJA. However, this remained controversial about the efficacy and safety of epinephrine for postoperative bleeding in TJA. The objective of our meta-analysis was to compare the overall effect and safety of epinephrine and placebo for postoperative bleeding in TJA...
