Congenital dysfibrinogenemia (CD) is a qualitative fibrinogen disorder caused by an abnormal fibrinogen molecule structure, leading to dysfunctional blood coagulation. This study describes 3 cases of dysfibrinogenemia identified in the unrelated Chinese pedigrees. Routine coagulation screening tests were performed on the probands and their families. ⋯ SEM of the patient's fibrin clot was found to be abnormal. Results indicate that the 3 probands with dysfibrinogenemia were caused by mutations of Aα chain Arg16His. Mutation of this fibrinogen induced dysfunction of plasma fibrinogen.

Comparative Study
Chest CT with iterative reconstruction algorithms for airway stent evaluation in patients with malignant obstructive tracheobronchial diseases.
The aim of the study was to investigate the image quality of low-dose CT images with different reconstruction algorithms including filtered back projection (FBP), hybrid iterative reconstruction (HIR), and iterative model reconstruction (IMR) algorithms by comparison of routine dose images with FBP reconstruction, in patients with malignant obstructive tracheobronchial diseases. In total, 60 patients (59 ± 9.3 years, 37 males) with airway stent who are randomly assigned into 2 groups (routine-dose [RD] and low-dose [LD] group, 30 for each) underwent chest CT on a 256-slice CT (RD-group 120 kV, 250 mAs, LD-group 120 kV, 120 mAs). Images were reconstructed with filtered back projection (FBP) algorithm in the RD group, whereas with FBP, HIR and IMR algorithms in the LD group. ⋯ Significant higher image noise and lower score of subjective image quality were observed in LD-FBP images (all P < 0.05). Both IMR and HIR improved image quality of low-dose chest CT by comparison of routine dose images reconstructed with FBP. Meanwhile, IMR allows further image quality improvement than HIR.

The aim of the study is to evaluate the epidemiology and clinical features of sepsis-induced cardiomyopathy (SICM). A retrospective cohort study was conducted. A total of 210 adult patients with sepsis or septic shock admitted to a Japanese tertiary care hospital from January 1, 2013, to December 31, 2015, who underwent transthoracic echocardiography (TTE) on admission. ⋯ Lengths of hospital and ICU stay were significantly longer in patients with SICM than in those without SICM (median, 43 vs 26 days, P = 0.04; 9 vs 5 days, P < 0.01). SICM developed in 13.8% of patients with sepsis and septic shock. A younger age, higher lactate levels on admission and history of HF were risk factors.

Observational Study
Spontaneously removed biliary stent drainage versus T-tube drainage after laparoscopic common bile duct exploration.
Several studies have shown the safety and feasibility of laparoscopic common bile duct exploration (LCBDE) as a minimally invasive treatment options for choledocholithiasis. Use of T-tube or biliary stent drainage tube placement after laparoscopic choledochotomy for common bile duct (CBD) stones is still under debate. This study tried to confirm the safety of spontaneously removable biliary stent in the distal CBD after LCBDE to allow choledochus primary closure. ⋯ Otherwise, Bile leakage between the two groups had no significant difference (P > 0.05). The biliary stent drainage tube was excreted spontaneously 4 to 14 days after surgery with the exception of one case, where endoscopic removal of biliary tube was required due to failure of its spontaneous discharge. LCBDE with primary closure and use of spontaneously removable biliary stent drainage showed advantage over the use of traditional T-tube drainage in patients with choledocholithiasis.

Comparative Study Observational Study
A mobile application improves therapy-adherence rates in elderly patients undergoing rehabilitation: A crossover design study comparing documentation via iPad with paper-based control.
Medication adherence is crucial for success in the management of patients with chronic conditions. This study analyzes whether a mobile application on a tablet aimed at supporting drug intake and vital sign parameter documentation affects adherence in elderly patients. Patients with coronary heart disease and no prior knowledge of tablet computers were recruited. ⋯ A mobile app for medication adherence increased objectively and subjectively measured adherence in elderly users undergoing rehabilitation. The findings have promising clinical implications: digital tools can assist chronic disease patients achieve adherence to medication and to blood pressure measurement. Although this requires initial offline training, it can reduce complications and clinical overload because of nonadherence.
