Objective(s): To assess efficacy and tolerability of preoperative capecitabine chemoradiation in rectal cancer.
Methods: Patients received radiotherapy 45 Gy in 25 fractions over 5 weeks and capecitabine 825 mg/m(2) twice daily throughout radiotherapy. Surgery was performed 5-7 weeks after radiotherapy. The primary endpoint was pathological complete response, secondary endpoints were downstaging and tolerability.
Results: Fifty-one patients were enrolled in a phase II study, median age 62 years (range 35-78). Sixty-three percent of tumours involved the lower third of the rectum, 45% were fixed. The median delivered radiotherapy dose was 44.8 Gy (range 39.6-45.0 Gy) over 33-49 days. The treatment-related grade 3 adverse events were diarrhoea (12%), skin reactions (8%) and asthenia (8%), with no grade 4 toxicity. Fifty patients underwent surgery (29 conservative) and 1 patient refused. The pathological complete response rate was 20% and a further 10% of patients had minimal residual disease. Additional tumour downstaging was seen in 28% of patients and the sphincter preservation rate was 58%.
Conclusions: Preoperative capecitabine chemoradiation is well tolerated and its efficacy supports further exploration, both as a single agent and as part of new therapeutic strategies.

Department of Surgery, Japan Community Healthcare Organization Tokuyama Central Hospital, 1-1 Koda-Cho, Shunan, Yamaguchi, 745-0822, Japan.
Purpose: We aimed to identify the risk factors for severe neutropenia in the early phase of trifluridine-tipiracil (FTD/TPI) treatment, and their impact on overall survival (OS).
Methods: This single-center retrospective study included patients with unresectable metastatic colorectal cancer who were treated with FTD/TPI. The primary endpoint was OS, and the secondary endpoint was severe neutropenia during the first and second cycles of FTD/TPI.

Background: The global pandemic caused by SARS-CoV-2 has resulted in millions of people experiencing long COVID condition, a range of persistent symptoms following the acute phase, with an estimated prevalence of 27%-64%.
Materials And Methods: To understand its pathophysiology, we conducted a longitudinal study on viral load and cytokine dynamics in individuals with confirmed SARS-CoV-2 infection. We used reverse transcriptase droplet digital PCR to quantify viral RNA from nasopharyngeal swabs and employed multiplex technology to measure plasma cytokine levels in a cohort of people with SARS-CoV-2 infection.

The Internet of Medical Things (IoMT) has revolutionized healthcare by bringing real-time monitoring and data-driven treatments. Nevertheless, the security of communication between IoMT devices and servers remains a huge problem because of the inherent sensitivity of the health data and susceptibility to cyber threats. Current security solutions, including simple password-based authentication and standard Public Key Infrastructure (PKI) approaches, typically do not achieve an appropriate balance between security and low computational overhead, resulting in the possibility of performance bottlenecks and increased vulnerability to attacks.
