Evaluation of 4-hand reduction for obturator hernia with the guidance of sonography as a new treatment strategy: A retrospective study.

To evaluate the effectiveness of 4-hand reduction for obturator hernia with the guidance of sonography (FROGS) as a new treatment strategy for obturator hernia. Since November 2019, FROGS was performed for all patients with obturator hernia at our emergency department. We retrospectively compared the clinical data of 20 patients who underwent FROGS (after FROGS group) to those of 23 patients who did not (before FROGS group). All patients except one were female. The male-to-female ratio, age, duration of symptoms, lesion site, and predisposing factors did not significantly differ between groups. However, the diameter of the prolapsed bowel and the body mass index of the after FROGS group were significantly larger and lower, respectively. Manual reduction was successfully performed for all 20 patients in the after FROGS group, and bowel resection was avoided for all 20 cases. However, 14 patients in the before FROGS group underwent manual reduction; of these, only one was successfully treated using a method other than FROGS, and 8 patients underwent bowel resection. There were no significant differences between groups in terms of postprocedural complications or mortality within 30 days of hernia presentation. The FROGS technique was safe and reproducible and could be used as the first choice of treatment for patients with obturator hernia.

Dissecting cricket genomes for the advancement of entomology and entomophagy.

Significant advances in biophysical methods such as next-generation sequencing technologies have now opened the way to conduct evolutionary and applied research based on the genomic information of greatly diverse insects. Crickets belonging to Orthoptera (Insecta: Polyneoptera), one of the most flourishing groups of insects, have contributed to the development of multiple scientific fields including developmental biology and neuroscience and have been attractive targets in evolutionary ecology for their diverse ecological niches. In addition, crickets have recently gained recognition as food and feed. However, the genomic information underlying their biological basis and application research toward breeding is currently underrepresented. In this review, we summarize the progress of genomics of crickets. First, we outline the phylogenetic position of crickets in insects and then introduce recent studies on cricket genomics and transcriptomics in a variety of fields. Furthermore, we present findings from our analysis of polyneopteran genomes, with a particular focus on their large genome sizes, chromosome number, and repetitive sequences. Finally, how the cricket genome can be beneficial to the food industry is discussed. This review is expected to enhance greater recognition of how important the cricket genomes are to the multiple biological fields and how basic research based on cricket genome information can contribute to tackling global food security.
