ReviewChronic thromboembolic pulmonary hypertension: an underdiagnosed entity?
Chronic thromboembolic pulmonary hypertension (CTEPH) is the only cause of pulmonary hypertension for which there is a potential cure, which is in the form of pulmonary endarterectomy. There is a strong link between pulmonary embolism (PE) and the development of CTEPH. Although CTEPH was initially believed to be a rare complication, this belief has been reconsidered following several studies suggesting that up to 8.8% of patients develop CTEPH within the 2 years after PE. ⋯ Potential reasons for this include its often vague clinical presentation, the variable association of CTEPH with PE, and discrepancies when interpreting imaging studies. Underdiagnosis of CTEPH is preventing patients from accessing potentially curative therapy. Increased awareness about this condition is an important initial step to improving diagnostic rates and treatment.

Diabetic foot ulcers (DFUs) are a common complication of diabetes and present a significant health risk to patients, as well as impose a large economic burden. Evaluation for contributory factors that may impact general health or healing, such as hyperglycemia, peripheral artery disease, neuropathy, and nutritional status, is of the utmost importance. ⋯ Assessment and control of infection are critical, including determining the severity of the infection, which may drive therapeutic approaches. For recalcitrant ulcers, adjuvant therapies are used to hasten the healing process, and newer therapies are under investigation.

Hyperglycemia occurs frequently in hospitalized patients and affects patient outcomes, including mortality, inpatient complications, hospital length of stay, and overall hospital costs. Various degrees of glycemic control have been studied and consensus statements from the American Diabetes Association/American Association of Clinical Endocrinologists and The Endocrine Society recommend a target blood glucose range of 140 to 180 mg/dL in most hospitalized patients. Insulin is the preferred modality for treating all hospitalized patients with hyperglycemia, as it is adaptable to changing patient physiology over the course of hospitalization. ⋯ Similar to hyperglycemia, hypoglycemia is an independent risk factor for poor outcomes in hospitalized patients. Improvement in glycemic control throughout the hospital includes efforts from all health care providers. Institutions can encourage safe insulin use by using insulin algorithms, preprinted order sets, and hypoglycemia protocols, as well as by supporting patient and health care provider education.

Observational StudyDiabetes and stress hyperglycemia in the intensive care unit: outcomes after cardiac surgery.
Hyperglycemia is common in the post-cardiac surgery population and has been associated with increased mortality rates, surgical length of stay, and infection rates. Although hospitalized patients with diabetes are known to have more complications, recent studies in various hospital settings have reported worse outcomes in patients with stress hyperglycemia than in those with diabetes. ⋯ Maintaining a blood glucose range between 100 to 140 mg/dL in post-cardiac surgery patients was associated with a low mortality rate, low risk of hypoglycemia, and with complications rates that were similar in patients with diabetes and stress hyperglycemia.

Multicenter StudyEvaluation of the IDSA/ATS minor criteria for severe community-acquired pneumonia.
Our aim was to evaluate the minor criteria recommended by the 2007 Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) as predictors of 30-day mortality, the need for invasive mechanical ventilation, and/or the need for vasopressor support as markers of severity in patients hospitalized with community-acquired pneumonia (CAP). ⋯ Our results show that hypoxemia, multilobar infiltrates, and leukopenia were the most predictive minor criteria for 30-day mortality. In contrast, hypoxemia and confusion/disorientation were the 2 individual minor severe criteria that were more likely to require invasive mechanical ventilation and/or vasopressor support. At least 3 2007 IDSA/ATS minor severe criteria were associated with 30-day mortality and need for invasive mechanical ventilation and/or vasopressor support.
