  • 简介:AbstractFor the detection of steatosis, quantitative ultrasound imaging techniques have achieved great progress in past years. Magnetic resonance imaging proton density fat fraction is currently the most accurate test to detect hepatic steatosis. Some blood biomarkers correlate with non-alcoholic steatohepatitis, but the accuracy is modest. Regarding liver fibrosis, liver stiffness measurement by transient elastography (TE) has high accuracy and is widely used across the world. Magnetic resonance elastography is marginally better than TE but is limited by its cost and availability. Several blood biomarkers of fibrosis have been used in clinical trials and hold promise for selecting patients for treatment and monitoring treatment response. This article reviews new developments in the non-invasive assessment of non-alcoholic fatty liver disease (NAFLD). Accumulating evidence suggests that various non-invasive tests can be used to diagnose NAFLD, assess its severity, and predict the prognosis. Further studies are needed to determine the role of the tests as monitoring tools. We cannot overemphasize the importance of context in selecting appropriate tests.

  • 简介:AbstractPurpose:Liver is the most frequently injured organ in abdominal trauma. Today non-operative management (NOM) is considered as the standard of care in hemodynamically stable patients, with or without the adjunct of angioembolisation (AE). This systematic review assesses the incidence of complications in patients who sustained liver injuries and were treated with simple clinical observation. Given the differences in indications of treatment and severity of liver trauma and acknowledging the limitations of this study, an analysis of the results has been done in reference to the complications in patients who were treated with AE.Methods:A systematic literature review searched "liver trauma" , "hepatic trauma" , "conservative management" , "non operative management" on MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials databases, EMBASE, and Google Scholar, to identify studies published on the conservative management of traumatic liver injuries between January 1990 and June 2020. Patients with traumatic liver injuries (blunt and penetrating) treated by NOM, described at least one outcome of interests and provided morbidity outcomes from NOM were included in this study. Studies reported the outcome of NOM without separating liver from other solid organs; studies reported NOM complications together with those post-intervention; case reports; studies including less than 5 cases; studies not written in English; and studies including patients who had NOM with AE as primary management were excluded. Efficacy of NOM and overall morbidity and mortality were assessed, the specific causes of morbidity were investigated, and the American Association for the Surgery of Trauma classification was used in all the studies analysed. Statistical significance has been calculated using the Chi-square test.Results:A total of 19 studies qualified for inclusion criteria were in this review. The NOM success rate ranged from 85% to 99%. The most commonly reported complications were hepatic collection (3.1%), followed by bile leak (1.5%), with variability between the studies. Other complications included hepatic haematoma, bleeding, fistula, pseudoaneurysm, compartment syndrome, peritonitis, and gallbladder ischemia, all with an incidence below 1%.Conclusion:NOM with simple clinical observation showed an overall low incidence of complications, but higher for bile leak and collections. In patients with grade III and above injuries, the incidence of bile leak, collections and compartment syndrome did not show a statistically significant difference with the AE group. However, the latter result is limited by the small number of studies available and it requires further investigations.

  • 简介:AbstractWith the widespread adoption of advanced tourniquets, the mortality rate of limb wound hemorrhage has decreased significantly, and non-compressible torso hemorrhage has gradually occupied the leading position of potentially preventable death, both in military and civilian circumstances. With the emergence of novel hemostatic devices and materials, strategies for the management of non-compressible torso hemorrhage have changed significantly. This review summarizes the current treatment strategies and types of equipment for non-compressible torso hemorrhage and suggests future research directions, hoping to provide a comprehensive review for the medical personnel and researchers engaging in this field.

  • 简介:AbstractIncreasing evidence suggests that long non-coding RNAs (lncRNAs) are of vital importance for various biological processes, and dysregulation of lncRNAs is frequently associated with various diseases such as psoriasis. LncRNAs modulate gene expression at the transcriptional, post-transcriptional, and translational levels; however, the specific regulatory mechanisms of lncRNAs in psoriasis remain largely unexplored. This review provides an overview of recent studies investigating mechanisms and functions of lncRNAs in psoriasis, especially focusing on the role of lncRNAs in keratinocytes, T cells, and dendritic cells.

  • 简介:AbstractThe philosophy of abdominal injury management is currently changing from mandatory exploration to selective non-operative management (NOM). The patient with hemodynamic stability and absence of peritonitis should be managed non-operatively. NOM has an overall success rate of 80%—90%. It also can reduce the rate of non-therapeutic abdominal exploration, preserve organ function, and has been defined as the safest choice in experienced centers. However, NOM carries a risk of missed injury such as hollow organ injury, diaphragm injury, and delayed hemorrhage. Adjunct therapies such as angiography with embolization, endoscopic retrograde cholangiopancreatography with stenting, and percutaneous drainage could increase the chances of successful NOM. This article aims to describe the evolution of NOM and define its place in specific abdominal solid organ injury for the practitioner who faces this problem.

  • 简介:AbstractEndometriosis (EM) is a benign gynecological disease that affects the fertility and health of women of reproductive age; it is characterized by the presence of endometrial glands and stroma outside the uterine cavity. Although several hypotheses have been proposed to explain the underlying cause of EM, its pathogenesis remains obscure. Recently, non-coding RNAs were reported to be involved in the occurrence and development of EM. MicroRNAs and long non-coding RNAs are the main members of the non-coding RNA family that contribute to EM progression in various aspects, such as cell proliferation, apoptosis, invasion, and angiogenesis. Angiogenesis plays a pivotal role in the initiation and development of EM and provides a substantial background for the invasion, proliferation, and long-term growth of endometriotic implants. This review aimed to investigate the role of microRNAs and long non-coding RNAs in regulating angiogenesis in EM and discuss how this mechanism can be used for diagnostic and therapeutic purposes in EM.
