To compare the outcomes of different treatments for spontaneous intra-abdominal abscesses (IAA) in active Crohn's disease (CD).

A retrospective analysis of patients with CD between January 2007 and December 2018 was performed in two Belgian inflammatory bowel disease centers. selleck kinase inhibitor Successful conservative management was defined as complete resolution of abscesses without the need for bowel resection. The primary outcome was suboptimal evolution, defined as a composite outcome of recurrence of abscess, postoperative complications or the need for a non-elective resection.

Forty CD patients presenting with 43 independent episodes of spontaneous IAA development were included. One underwent immediate bowel resection. In all other 42 cases a conservative approach was taken, which led to a complete abscess resolution rate of 28.6% (12/42). The remaining abscesses required bowel resection. Anti-tumor necrosis factor (TNF) agent use was associated with successful conservative management (odds ratio [OR] 13.36, 95% confidence interval [CI] 11.19-15.52, P=0.006), while the opposite trend was found for corticosteroids (OR 0.14, 95% CI 0.02-1.26, P=0.055). There was a trend towards suboptimal evolution in case of previous bowel resection (OR 4.77, 95% CI 0.77-29.66, P=0.094) or in patients aged above 50 years (OR 5.17, 95% CI 0.86-30.91, P = 0.072).

Bowel resection appears to be inevitable in most CD patients presenting with IAA. An attempt at conservative treatment may be particularly successful with anti-TNF agents in younger patients who have not undergone previous bowel resection. Large-scale prospective studies are needed to confirm these findings.

A short-term longitudinal study design was used to conduct two waves of online surveys in March and April 2020. Participants comprised 107 medical staff in both waves of investigation. Self-efficacy, coping strategies, and perceived organizational support were reported at Wave 1, and PTSD symptoms were reported at Wave 2. Results indicated that (1) The prevalence of probable PTSD was 9.3% and 4.7% on the Chinese version of the Impact of Events Scale-Revised of 33 and 35, respectively. Local healthcare workers had greater risks of PTSD than the members of medical rescue teams. Doctors reported higher PTSD symptoms than nurses. (2) Perceived organizational support had a significant indirect effect on PTSD symptoms through the mediation of problem-focused coping strategies and the sequential mediating effect of coping self-efficacy and problem-focused coping strategies. The findings highlight the importance of providing adequate organizational support to reduce PTSD symptoms in frontline medical staff during the COVID-19 pandemic.
To discern the symptomatic features of coronavirus disease 2019 (COVID-19) and to evaluate the severity and prognosis of the disease.

In this retrospective cohort study, 932 hospitalized patients with COVID-19 in Wuhan were enrolled, including 52 severe and 880 non-severe cases. All patients were followed up for 3 months after discharge. The symptomatic features and follow-up data of the patients in both groups were analyzed and compared.

Of the 932 patients, fever (60.0%), cough (50.8%) and fatigue (36.4%) were the most common symptoms. In total, 32.7% of the severe cases presented with gastrointestinal symptoms at disease onset, including anorexia, nausea, vomiting or diarrhea, which was significantly higher than that of the non-severe group (P = 0.0015). The incidence of olfactory disturbance and dysgeusia was only 3.1% and 6.2%, respectively. After adjusting for age and sex, multivariate regression analysis showed that fever lasting for over 5 days (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.00-3.62, P=0.0498), anorexia at onset (OR 2.61, 95% CI 1.26-5.40, P=0.0096), and modified Medical Research Council level above grade 2 when dyspnea occurred (OR 14.19, 95% CI 7.01-28.71, P < 0.0001) were symptomatic risk factors for severe COVID-19. During the follow-up, cough (6.2%), dyspnea (7.2%), fatigue (1.8%), olfactory disturbance and dysgeusia (1.5%) were the significant remaining symptoms.

COVID-19 causes clusters of symptoms with multiple systems involved. Certain symptomatic characteristics have predictive value for severe COVID-19. Short-term follow-up data reveal that most patients have a good prognosis.

The Kuang-Luo rheological model is used to represent blood as a homogeneous continuum. This model includes the two primary non-Newtonian characteristics of blood, namely viscoplasticity and pseudoplasticity. This paper makes two contributions. First, the numerical challenges associated with zero strain rates and infinite viscosity, as a consequence of the yield stress in the Kuang-Luo model, were addressed by regularising the constitutive equation so that the viscosity tends towards a finite value at low strain rates. A two-relaxation-time operator, which exhibits improved performance over the single-relaxation-time operator and lower computational overhead than the multiple-relaxation-time operator, is employed in the collision process. The recursive relationship between the local strain rate and relaxation rate was addressed by use of an implicit solver for these two quantities.
