RESUMEN
Hard-to-heal wounds are a problem for both patients and caregivers. The biofi lm is one of the local factors of delayed healing. Wound hygiene carried out in 4 steps (cleansing, debridement, refashion - care of the edges, and dressing) constitutes the basis of proactive and curative anti-biofi lm strategies.

Despite progress in the prevention of pressure injuries (PIs), they remain a challenging public health problem because of their frequency and morbidity. Protection of the skin by multilayer silicone foam dressings may be an adjuvant measure to prevent PIs in high-risk patients. Despite the available clinical data and published recommendations on this measure, caregivers face difficulties in identifying patients who would benefit from this adjuvant measure. The objective of this work was to define the profiles of high-risk patients who would benefit optimally from this measure in combination with basic preventive procedures. This consensual expert opinion was drawn up using two methods: the Nominal Group Technique with eight medical and paramedical experts, and the Delphi process with 16 experts. The bases for this expert consensual opinion were a formal search and analysis of the published literature regarding evidence on the prevention of PIs using multilayer silicone foam dressings. The consensual expert opinion reported here addresses five proposals mostly intended to define patients who would benefit from the use of a multilayer silicone foam dressing (≥4 layers) to prevent PIs (sacrum and heels).

OBJECTIVE: To evaluate the clinical course of and risk factors for arterial thrombotic events in adult inpatients with coronavirus disease 2019 (COVID-19). METHODS: All consecutive adult patients admitted for COVID-19 infection in a referral center in France and discharged from the hospital between April 1 and April 30, 2020, were included. All arterial thrombotic events that occurred through discharge were considered for analysis. Epidemiologic, demographic, clinical, laboratory, treatment, and outcome data were extracted from electronic medical records with use of a standardized data collection form. RESULTS: Overall, 531 COVID-19+ patients were analyzed. Among them, 30 (5.6%) experienced arterial thrombotic events. Arterial thrombotic events in the setting of COVID-19 infection happened at a median of 11 (5-20) days after the first symptoms of infection; occurred in high-risk patients according to traditional cardiovascular risk factors; had an atypical pattern, such as thrombosis of the aorta, upper limb, or renal arteries or cerebral microvasculopathy in 7 (23.3%) cases; and were associated with an in-hospital mortality rate of 40%. Arterial thrombotic events increased the risk of death by 3-fold in COVID-19+ patients (hazard ratio, 2.96; 95% CI, 1.4 to 4.7; P=.002). A subdistribution survival hazard model showed that a concentration of D-dimer above 1250 ng/mL increased the risk of arterial thrombotic events in COVID-19+ patients by more than 7 (subdistribution hazard ratio, 7.68; 95% CI, 2.9 to 20.6; P<.001). CONCLUSION: A dramatically high rate of in-hospital death was observed in patients who suffered arterial thrombotic events in the setting of COVID-19 infection. A D-dimer level above 1250 ng/mL at entry may identify COVID-19+ patients at risk for arterial thrombotic events.

BACKGROUND: The optimal treatment for patients with severe coronavirus-19 disease (COVID-19) and hyper-inflammation remains debated. MATERIAL AND METHODS: A cohort study was designed to evaluate whether a therapeutic algorithm using steroids with or without interleukin-1 antagonist (anakinra) could prevent death/invasive ventilation. Patients with a ≥5-day evolution since symptoms onset, with hyper-inflammation (CRP≥50mg/L), requiring 3-5 L/min oxygen, received methylprednisolone alone. Patients needing ≥6 L/min received methylprednisolone + subcutaneous anakinra daily either frontline or in case clinical deterioration upon corticosteroids alone. Death rate and death or intensive care unit (ICU) invasive ventilation rate at Day 15, with Odds Ratio (OR) and 95% CIs, were determined according to logistic regression and propensity scores. A Bayesian analysis estimated the treatment effects. RESULTS: Of 108 consecutive patients, 70 patients received glucocorticoids alone. The control group comprised 63 patients receiving standard of care. In the corticosteroid±stanakinra group (n = 108), death rate was 20.4%, versus 30.2% in the controls, indicating a 30% relative decrease in death risk and a number of 10 patients to treat to avoid a death (p = 0.15). Using propensity scores a per-protocol analysis showed an OR for COVID-19-related death of 0.9 (95%CI [0.80-1.01], p = 0.067). On Bayesian analysis, the posterior probability of any mortality benefit with corticosteroids+/-anakinra was 87.5%, with a 7.8% probability of treatment-related harm. Pre-existing diabetes exacerbation occurred in 29 of 108 patients (26.9%). CONCLUSION: In COVID-19 non-ICU inpatients at the cytokine release phase, corticosteroids with or without anakinra were associated with a 30% decrease of death risk on Day 15.

A 70-year-old patient was admitted with rapidly progressive cognitive decline associated with limitations in activities of daily living, weight loss and cerebellar ataxia. The diagnosis of giant cell arteritis (GCA) with vascular involvement was made, based on the presence of a metabolically active vasculitis of the brachiocephalic trunk on 18FDG-PET imaging. Temporal artery biopsy also revealed pan-arteritis. A progressive regression of cognitive disorders occurred under corticosteroid treatment and immunosuppressive therapy. Previously published case reports concerning this atypical presentation of GCA are scarce. They suggest that numerous cognitive symptoms, such as impairment of short-term memory, disorientation, delirium, impaired attention or visual hallucinations might be related to GCA. Thus, this diagnosis should be considered as a curable cause of unexplained cognitive impairment associated with weight loss and systemic inflammation.

Exudate control is important in the management of both acute and chronic wounds. A new category of absorbent dressings that contain superabsorbent particles promises high absorbency. The aim of this multicentre, prospective, non-comparative observational study was to evaluate the clinical efficacy and absorbent capacity of a superabsorbent dressing. Fifteen inpatients and outpatients with highly exuding wounds were included. Most patients (n=8) (53%) had chronic wounds; 20% (n=3) had ulcerating tumours. The superabsorbent dressing was used as a primary or a secondary dressing. Assessment was on day 0 (start), day 3 and day 7 (end of study). The study looked at wound bed and periwound skin condition, exudate production, pain upon dressing removal, reason for dressing removal, and frequency of dressing changes. A clinical visual scoring tool was used, together with digital photographs, which were assessed by the same experienced clinician. All 15 patients completed the study, during which no adverse events were noted. At day 7, maceration had reduced from 46.7% (n=7) at day 0 to 6.7% (n=1). After only 3 days, dressing change frequency was reduced from once daily to twice weekly in 80% (n=12) of patients. The superabsorbent dressing seems to reduce complications associated with exudate production, stimulate wound healing and increase patient comfort; it may also save time and costs for caregivers.

Across Europe, wound care management is organized differently, and in some countries such as the UK or Denmark, wound healing centres have been implemented. In France, a large number of health professionals are not sufficiently educated in wound care management during their vocational training. The rapid evolution of dressings has changed wound management practices and has given rise to new professional recommendations. This national survey was carried out in France in 2009, including 465 health professionals, to determine the criteria they use to choose a dressing and their habits of care with acute or chronic wounds. Around 73% of respondents were nurses and, on average, participants took care of 43 wounds per month. It was also found that 89% of the health professionals who took part prefer the sequential treatment of the wound based on its appearance. Regardless of whether the wound is acute or chronic, the priorities for wound care and the choice of dressing are the management of the exudate and the prevention or treatment of infection. These results put into evidence the adequacy of the recommendations by these practitioners and the good correlation between the choice of dressing and the local therapeutic goal. To reach the same level of expertise, the professional training for health professionals who are less frequently involved in wound care is necessary.
