Background: Partial replantation (i.e. replacement of the extraperitoneal portion of the catheter with creation of a new subcutaneous tunnel) has been suggested to avoid catheter removal in patients with persistent exit-site/tunnel infection (ESTI). However, published experience with this technique is limited.
Methods: Partial replantation was performed on an outpatient basis under local anesthesia for seven patients with persistent ESTI of >3 months duration. All patients resumed CAPD immediately following surgery.
Results: One patient had dialysate leakage less than 1 week after surgery that required catheter removal. The other patients had no complications and mean catheter survival following surgery was 7. 7 months (range 3.5-13 months). There was no recurrence of ESTI after surgery, although two patients presented with exit-site infection unrelated to the initial episode (i.e. different organism, long latency). Three other patients presented with episodes of peritonitis unrelated to surgery (i.e. delay >1 month) or ESTI (i.e. different organism).
Conclusions: Partial replantation allows significant prolongation of catheter survival without major complications or interruption of CAPD. This novel procedure appears to be an appropriate alternative to catheter removal for the management of persistent ESTI. However, further studies are needed to prospectively compare partial replantation with catheter removal.

Continuous cropping obstacle has been becoming the bottleneck for the stable development of morel cultivation. The allelopathic effect of soil allelochemicals may play an instrumental role in the morel soil sickness. In this study, the allelochemicals were identified by gas chromatography-mass spectrometry (GC-MS) combined with in vitro bioassay.

Article Synopsis
- Work in agriculture is hazardous, particularly because of mechanical equipment and the high risk of hand injuries.
- A case study describes a 55-year-old man who suffered a non-work-related finger amputation and underwent an unusual replantation procedure by a novice surgeon.
- Despite challenges like the lack of vascular reconstruction, the reattached finger surprisingly retained some blood supply; further surgeries and rehabilitation ultimately restored its function.

Article Synopsis
- Amputation due to high-energy trauma often results in complex tissue damage, leading to a high revision rate, but successful reconstructions can improve quality of life.
- This study examined a protocol for revascularizing and reconstructing the hand after traumatic amputation using an anterolateral thigh flap (ALT) in patients with severe injuries.
- Out of 11 patients treated over seven years, all limbs survived, with most achieving good functional recovery, although one case required further intervention due to partial flap necrosis.
Comparative genomic analysis of strain B1 reveals conserved potential for adaptation to endophytism and plant growth promotion.

In our study, we aimed to explore the genomic and phenotypic traits of strain B1, which was isolated from root material of healthy apple plants, to adapt to the endophytic lifestyle and promote plant growth. We identified putative genes encoding proteins involved in chemotaxis, flagella biosynthesis, biofilm formation, secretory systems, detoxification, transporters, and transcription regulation. Furthermore, B1 exhibited both swarming and swimming motilities, along with biofilm formation.
