Review Comparative Study[Clinical and biological features of patients with essential thrombocythaemia according to their mutational status JAK2 or CALR: Single-center study of 40 patients and review of the literature].
Somatic mutations in the calreticulin gene (CALR) were recently described in essential thrombocythemia (ET) and primary myelofibrosis with non-mutated JAK2 or MPL. The aim of this single-center study was to compare the clinical and biological features of ET patients according to their mutational status. ⋯ JAK2 and CALR mutation screening in ET has a diagnostic value. Each mutation displays a distinct phenotype with uncertain impact on long-term outcome.

Prevalence and clinical distribution of multidrug-resistant bacteria (3537 isolates) in a tertiary Chinese hospital (January 2012-December 2013).
Multidrug-resistant organisms (MDROs) have become a widespread serious problem in recent years. Our objective was to determine the prevalence and clinical distribution of MDROs in a tertiary care hospital in China from January 1, 2012 to December 31, 2013. ⋯ High prevalence of MDROs has emerged in our hospital, particular in various ICU and surgical department. The effective way to prevent the further spread of MDROs is to strengthen the protection of respiratory tract and surgical wounds.

Successful treatment of renal light chain (AL) amyloidosis with bortezomib and dexamethasone (VD).
To assess the efficacy and tolerability of bortezomib with dexamethasone for patients with renal light chain (AL) amyloidosis. ⋯ VD produces rapid, deep and durable hematological responses and renal responses in the majority of patients with newly diagnosed renal AL. It is well tolerated. This treatment may be a good option as first-line treatment for renal AL amyloidosis patients.

Traumatic brain injury (TBI) is a major health concern in industrialised countries. Sleep and wake disturbances are among the most persistent and disabling sequelae after TBI. Yet, despite the widespread complaints of post-TBI sleep and wake disturbances, studies on their etiology, pathophysiology, and treatments remain inconclusive. ⋯ A second goal is to outline the various causes of post-TBI sleep-wake disturbances. Globally, although sleep-wake complaints are reported in all studies and across all levels of severity, consensus regarding the objective nature of these disturbances is not unanimous and varies widely across studies. In order to optimise recovery in TBI survivors, further studies are required to shed light on the complexity and heterogeneity of post-TBI sleep and wake disturbances, and to fully grasp the best timing and approach for intervention.

Shift work comprises work schedules that extend beyond the typical "nine-to-five" workday, wherein schedules often comprise early work start, compressed work weeks with 12-hour shifts, and night work. According to recent American and European surveys, between 15 and 30% of adult workers are engaged in some type of shift work, with 19% of the European population reportedly working at least 2 hours between 22:00 and 05:00. The 2005 International Classification of Sleep Disorders estimates that a shift work sleep disorder can be found in 2-5% of workers. ⋯ Indeed, workers suffering from a shift work sleep-wake disorder can fall asleep involuntarily at work or while driving back home after a night shift. Working on atypical shifts has important socioeconomic impacts as it leads to an increased risk of accidents, workers' impairment and danger to public safety, especially at night. The aim of the present review is to review the circadian and sleep-wake disturbances associated with shift work as well as their medical impacts.
