Objectives:
:An increasing number of people are affected by sleep problems every year. The current study presents findings from experiments that utilize a mobile application-based cognitive-behavioral treatment for insomnia (CBT-I).
Methods:
:Our application aims to alleviate insomnia symptoms by providing real-time and direct interventions in people’s daily lives. We recruited 50 participants to test the effectiveness of the app via a six-week-long prospective experiment.
Results:
:We find that insomnia symptoms are reduced significantly for both the treatment group, who used the app, and the control group, who watched educational videos [F(2,39)=60.82, p<0.001]. Sleep efficiency improved more quickly in the treatment group than in the control group. Participants who followed higher compliance to the intervention reduced their wake after sleep onset (WASO) time more substantially.
Conclusion
:Our results suggest that app-based CBT-I interventions may have additional benefits for enhancing objective sleep quality, including sleep efficiency or WASO, compared to sleep hygiene education. The preliminary findings of the current research shed light on future mobile intervention apps’ design choices for insomnia.

Carval syndrome is a severe heartworm infection where the worms have migrated to the right atrium and vena cava; this condition is associated with a myriad of clinical signs. Several non-surgical and interventional methods are currently used for mechanical worm removal. However, the success rate and complications related to these methods are heavily dependent on methodology and retrieval devices used. In this study, we developed a catheter-guided heartworm removal method using a retrieval basket that can easily access pulmonary arteries and increase the number of worms removed per procedure. With this technique, we successfully treated four dogs with caval syndrome.

The surgical treatments for aortic arch aneurysm are thought to be very invasive procedures, and high morbidity and mortality rates have been reported after aortic arch aneurysm operations. Many surgeons currently prefer the insertion of a stent-graft rather than an operation for treating an aortic arch aneurysm and if needed, with bypass of the subclavian or carotid arteries, which is called the 'hybrid method'. We managed one patient with an aortic arch aneurysm by using the hybrid method, and so we report on this case with a review of the relevant literature.

We sought the novel concept, transcript capacity (TC) and analyzed TC. Our approach to estimate TC was through an in silico method. TC refers to the capacity that a transcript exerts in a cell as enzyme or protein function after translation. We used the genome-wide association study (GWAS) beta effect and transcription level in RNA-sequencing to estimate TC. The trait was body fat percent and the transcript reads were obtained from the human protein atlas. The assumption was that the GWAS beta effect is the gene’s effect and TC was related to the corresponding gene effect and transcript reads. Further, we surveyed gene ontology (GO) in the highest TC and the lowest TC genes. The most frequent GOs with the highest TC were neuronal-related and cell projection organization related. The most frequent GOs with the lowest TC were wound-healing related and embryo development related. We expect that our analysis contributes to estimating TC in the diverse species and playing a benevolent role to the new bioinformatic analysis.

We analyzed the manner and cause of death in 1,193 forensic autopsies from the Jungbu province (central part of South Korea) conducted by the National Forensic Service Daejeon Institute in 2022. Analysis of the manner of deaths revealed that 43.1% (514/1,193 cases) were natural deaths; 42.8% (511/1,193 cases) were unnatural deaths; and 14.1% (168/1,193 cases) were unknown. Among the unnatural deaths, the major manner of death was 44.6% (228/511 cases) by accidents, 34.1% (174/511 cases) by suicide, 13.5% (69/511 cases) undetermined, and 7.8% (40/511 cases) by homicide. Among the unnatural deaths, the major causes of death was 38.4% (196/511 cases) by trauma, 20.4% (104/511 cases) by poisoning, and 17.6% (90/511 cases) by asphyxia. Falling was the major cause of death by trauma (58.7%, 115/196 cases), and strangulation was the major cause of death by asphyxia (75.6%, 68/90 cases). Among the natural deaths, heart disease was the major cause (46.7%, 240/514 cases), followed by endocrine, nutritional and metabolic diseases (14.0%, 72/514 cases). A time-series statistical analysis and comparison of the manner and cause of deaths in this province may facilitate more advanced interpretations relating to both public safety and healthcare in the future.

Korean Journal of Veterinary Research 2014;54(3):193-196
A 2-year old castrated male Alaskan malamute was referred with primary complaints of marked anemia, hemeglobinuria and depression. Laboratory tests revealed canine babesiois with severe anemia. The dog was treated by blood transfusion and beneril (diminazene aceturate, 3.5 mg/kg IM). Two days after Beneril injection, the dog suddenly showed ataxia progressing to paresis. MRI revealed irregularly diffused lesions in the cerebellum. The case was tentatively diagnosed as cerebellar encephalopathy caused by diminazene toxicity. The dog successfully recovered following steroid therapy.
