RESUMEN
BACKGROUND: The overburdening of the healthcare system during the coronavirus disease 19 (COVID-19) pandemic is driving the need to create new tools to improve the management of inter-hospital transport for patients with a severe COVID-19 infection. OBJECTIVE: The aim of this study was to analyse the usefulness of the application of a prioritization score (IHTCOVID-19) for inter-hospital transfer of patients with COVID-19 infection. METHODS: The study has a quasi-experimental design and was conducted on the Medical Emergency System, the pre-hospital emergency department of the public company belonging to the Autonomous Government of Catalonia that manages urgent healthcare in the region. Patients with a severe COVID-19 infection requiring inter-hospital transport were consecutively included. The pre-intervention period was from 1 to 31 March 2020, and the intervention period with the IHTCOVID-19 score was from 1 to 30 April 2020 (from 8 am to 8 pm). The prioritization score comprises four priority categories, with Priority 0 being the highest and Priority 3 being the lowest. Inter-hospital transfer (IHT) management times (alert-assignment time, resource management time and total central management time) and their variability were evaluated according to whether or not the IHTCOVID-19 score was applied. RESULTS: A total of 344 IHTs were included: 189 (54.9%) in the pre-intervention period and 155 (45.1%) in the post-intervention period. The majority of patients were male and the most frequent age range was between 50 and 70 years. According to the IHTCOVID-19 score, 12 (3.5%) transfers were classified as Priority 0, 66 (19.4%) as Priority 1, 247 (71.8%) as Priority 2 and 19 (5.6%) as Priority 3. Overall, with the application of the IHTCOVID-19 score, there was a significant reduction in total central management time [from 112.4 (inter-quartile range (IQR) 281.3) to 89.8 min (IQR 154.9); P = 0.012]. This significant reduction was observed in Priority 0 patients [286.2 (IQR 218.5) to 42.0 min (IQR 58); P = 0.018] and Priority 1 patients [130.3 (IQR 297.3) to 75.4 min (IQR 91.1); P = 0.034]. After applying the IHTCOVID-19 score, the average time of the process decreased by 22.6 min, and variability was reduced from 618.1 to 324.0 min. CONCLUSION: The application of the IHTCOVID-19 score in patients with a severe COVID-19 infection reduces IHT management times and variability.

OBJECTIVES: Von Frey monofilaments (VFM) and Electronic von Frey are used as quantitative sensory testing to explore mechanical hyperalgesia. The aim of the study was to determine VFM and Electronic von Frey reproducibility and the time required for testing undamaged areas in volunteers and surgical in-hospital patients. METHODS: Prospective study in 2 groups of individuals without neurological disorders and not receiving treatments that alter sensorial response. Group 1 was formed by 30 healthy volunteers and group 2 by 28 patients after knee arthroplasty who received unilateral femoral block as postoperative analgesia. Testing was performed by 2 trained investigators in the forearm and abdominal wall and repeated 24 hours later. Pain threshold was determined as the VMF or the pressure rate applied with the Electronic von Frey referred to as unpleasant. The time used in each test was measured. Intraobserver and interobserver reproducibility were analyzed by means of Kappa and Lin coefficients. RESULTS: Intraobserver and interobserver reproducibility for VFM was only fair or moderate in both groups (Kappa<0.6). Intraobserver reproducibility for Electronic von Frey was good in Group 1 (Lin 0.61 to 0.8) and almost perfect in Group 2 (Lin>0.8). No differences were found between the 2 tested areas. Time used was 6.03 and 3.16 minutes for VFM and Electronic von Frey, respectively. DISCUSSION: Exploration of mechanical allodynia in postoperative patients requires rapid and reliable quantitative sensory testing. Electronic von Frey was more reliable and rapid than VFM in exploring mechanical pain thresholds in undamaged areas in volunteers and patients. Further studies are required to confirm whether these results can be extrapolated to areas affected by surgery.

EGFR overexpression has been implicated in the development of head and neck squamous cell carcinoma (HNSCC). This study evaluates the prognostic ability of four polymorphisms in EGFR gene for patients diagnosed with HNSCC and treated with chemoradiation. EGFR polymorphisms in the promoter region were not associated with clinical or pathological characteristics. In relation to R497K polymorphism, patients with the Arg/Arg genotype showed the highest risk of disease-specificity mortality and none of the patients with the Lys/Lys genotype died throughout the follow-up period of the study. Patients with (CA)(n) repeats <17 in both alleles tended toward inferior overall survival compared with those with (CA)(n) repeats > or = 17 in both alleles (p=0.07). Moreover, the distribution of patients with any (CA)(n) repeats > or = 17 and both alleles <17 was statistically different across patients who were recorded as having partial response or no response to therapy (p=0.034). Combination analysis of both polymorphisms, (CA)(n) repeats and R497K, suggests that these polymorphisms may be associated with clinical outcome in patients treated with chemoradiation.
