Treatment of venous ulcers involves compression and elevation of the lower extremities, plus exercise if tolerated. Diabetic foot ulcers are managed by offloading the foot and, if necessary, treating the underlying peripheral arterial disease. Pressure ulcers are managed by offloading the affected area.Guidelines for the diagnosis and treatment of Clostridioides difficile infection have recently been updated. Risk factors include recent exposure to health care facilities or antibiotics, especially clindamycin. C. difficile infection is characterized by a wide range of symptoms, from mild or moderate diarrhea to severe disease with pseudomembranous colitis, colonic ileus, toxic megacolon, sepsis, or death. C. difficile infection should be considered in patients who are not taking laxatives and have three or more episodes of unexplained, unformed stools in 24 hours. Testing in these patients should start with enzyme immunoassays for glutamate dehydrogenase and toxins A and B or nucleic acid amplification testing. In children older than 12 months, testing is recommended only for those with prolonged diarrhea and risk factors. Treatment depends on whether the episode is an initial vs. recurrent infection and on the severity of the infection based on white blood cell count, serum creatinine level, and other clinical signs and symptoms. For an initial episode of nonsevere C. difficile infection, oral vancomycin or oral fidaxomicin is recommended. MEK phosphorylation Metronidazole is no longer recommended as first-line therapy for adults. Fecal microbiota transplantation is a reasonable treatment option with high cure rates in patients who have had multiple recurrent episodes and have received appropriate antibiotic therapy for at least three of the episodes. Good antibiotic stewardship is a key strategy to decrease rates of C. difficile infection. In routine or endemic settings, hands should be cleaned with either soap and water or an alcohol-based product, but during outbreaks soap and water is superior. The Infectious Diseases Society of America does not recommend the use of probiotics for prevention of C. difficile infection.BACKGROUND Fast food is cross-sectionally associated with having overweight and obesity in young children. OBJECTIVES To examine whether fast food intake independently contributes to the development of overweight and obesity among preschool-age children. METHODS Prospective cohort of 3- to 5-year-old children (n = 541) followed for 1 year. Children's height and weight were objectively measured at baseline and study end. Parents reported their child's fast food intake frequency in the past week from 11 chain fast food restaurants in six online follow-up surveys, completed approximately 8 weeks apart. Poisson regression with robust standard errors modelled the risk of a child increasing in weight status (ie, transitioning from a having a healthy weight to having overweight or from having overweight to having obesity) over the study period in relation to their average weekly fast food intake, adjusted for sociodemographics, child obesogenic behaviours, and parent weight status. RESULTS At baseline, 18.1% of children had overweight and 9.8% had obesity; 8.1% of children transitioned to a greater weight status over the 1-year period. Mean fast food intake frequency among consumers was 2.1 (SD 1.4) times per week. The risk of increasing in weight status increased linearly with each additional time fast food was consumed in an average week over the study year (RR 1.38; 95% CI, 1.13-1.67; P  less then  .01). CONCLUSIONS Greater fast food intake over 1 year was associated with increasing weight status during that time in this preschool-age cohort. © 2020 World Obesity Federation.INTRODUCTION We have routinely used thrombin generation to investigate patients with unclassified bleeding disorder (UBD). AIMS To investigate haemostatic abnormalities in patients with UBD that had abnormal thrombin generation on at least one occasion. METHODS Investigation of 13 known UBD patients with thrombin generation and detailed haemostatic testing was undertaken including TFPI assays but also thrombomodulin and fibrinogen-γ. RESULTS 12 females and 1 male were included. No patient had a platelet function disorder or coagulation factor deficiency that explained the bleeding phenotype, though 2 patients had factor deficiencies; a factor X of 0.41 IU/mL and a factor XI of 0.51 IU/mL. ThromboGenomics revealed variants for these factors but no other abnormalities. Patients were included who previously had either prolonged lag time or decreased endogenous thrombin potential (ETP) via high dose tissue factor (5 pmol/L) or low dose tissue factor (1.5 pmol/L) with corn trypsin inhibitor (CTI). Tissue factor pathway inhibitor (TFPI) activity was significantly increased (P  less then  .001; increased in 8 patients) compared with controls and abnormalities in soluble thrombomodulin (2 patients), fibrinogen-γ (1 patient) and tPA (4 patients for each) were seen. Total and free TFPI levels were not increased. Mixing studies of patient plasma with 5050 normal plasma for thrombin generation via low dose tissue factor failed to correct the ETP consistent with ongoing inhibition. Addition of an anti-TFPI antibody partially corrected thrombin generation to normal levels. TFPI sequencing was unremarkable. CONCLUSION TFPI activity may be increased in a subset of UBD patients. Further research studies are warranted in UBD patients for coagulation inhibitor abnormalities. © 2020 John Wiley & Sons Ltd.Synthetic cannabinoids (SCBs), designer drugs marketed as legal alternatives to marijuana, act as ligands to cannabinoid receptors; however, they have increased binding affinity and potency, resulting in toxicity symptoms such as cardiovascular incidents, seizures, and potentially death. N-(adamantan-1-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamide (STS-135) is a third generation SCB. When incubated with hepatocytes, it undergoes oxidation, hydrolysis, and glucuronidation, resulting in 29 metabolites, with monohydroxy STS-135 (M25) and dihydroxy STS-135 (M21) being the predominant metabolites. The enzymes responsible for this oxidative metabolism were unknown. Thus, the aim of this study was to identify the cytochrome P450 (P450s or CYPs) enzymes involved in the oxidative metabolism of STS-135. In this study, STS-135 was incubated with liver, intestinal, and brain microsomes and recombinant P450s to determine the enzymes involved in its metabolism. Metabolite quantification was carried out using ultra-performance liquid chromatography.
