Is the Increase in Record of Skin Wounds in Hospitalized Patients in Internal Medicine Units a Side Effect of the COVID-19 Pandemic?

Wound care is an important public health challenge that is present in all areas of the healthcare system, whether in hospitals, long term care institutions or in the community. We aimed to quantify the number of skin wounds reported after and during the COVID-19 pandemic. This descriptive longitudinal retrospective study compared of wound records in patients hospitalized in the internal medicine service during the first year of the COVID-19 pandemic (from 1 March 2020, to 28 February 2021) and previous-year to the outbreak (from 1 January 2019, to 31 December 2019). A sample of 1979 episodes was collected corresponding to 932 inpatients, 434 from the pre-pandemic year and 498 from the first year of COVID-19 pandemic; 147 inpatients were diagnosed with SARS-CoV-2 infection (3.2%). The percentage of wound episodes in the first year of the COVID-19 pandemic was higher than the pre-pandemic year, 17.9% (1092/6090) versus 15% (887/5906), with a significant increase in the months with the highest incidence of COVID cases. This study shows an increase in the burden of wound care during the COVID-19 pandemic, and it could be attributable to the increase in the number of patients hospitalized for SARS-CoV-2 infection in internal medicine units.

Clinical Burden of Inpatient Wound Care in Internal Medicine Units During the First Wave of COVID-19 Outbreak.

OBJECTIVE: To explore the clinical burden and epidemiologic profile of hospitalized patients with wounds during the first wave of COVID-19. METHODS: A retrospective and observational study was conducted to analyze the inpatient episodes of wound care in the University Hospital of Salamanca (Spain) during the initial COVID-19 crisis from March 1, 2020, to June 1, 2020. Data were collected from nursing care reports and clinical discharge reports. Included patients were 18 years or older, had a hospital length of stay of 1 day or longer, and were hospitalized in an internal medicine unit. Surgical and traumatic wounds and pediatric patients were excluded. RESULTS: A total of 116 patients and 216 wounds were included. The overall wound prevalence was 7.6%, and incidence was 3.5% in the internal medicine units. Pressure injuries (PIs) were the most common wound type, and patients with COVID-19 had significantly higher PI risk (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.1-4.0; P = .042). Significant differences in PI staging were noted: 83.2% of wounds in patients with COVID-19 were stages I-II versus 67.8% in patients without COVID-19; the probability of stage III-IV PIs among patients without COVID-19 was doubled (OR, 2.3; 95% CI, 1.2-4.5; P = .009). The probability of acute wounds tripled in patients with COVID-19 (OR, 3.7; 95% CI, 2.1-6.6; P < .001). Patients with COVID-19 also had longer mean hospital stays and higher ICU admission rates. No case fatality rate differences were observed. CONCLUSIONS: In this context of clinical practice, protocolized assessment and implementation of preventive measures must be ensured among older adult populations, patients with associated comorbidities, and ICU patients.

Are there differences between COVID-19 and non-COVID-19 inpatient pressure injuries? Experiences in Internal Medicine Units.

BACKGROUND: Pressure Injuries (PIs) are major worldwide public health threats within the different health-care settings. OBJECTIVE: To describe and compare epidemiological and clinical features of PIs in COVID-19 patients and patients admitted for other causes in Internal Medicine Units during the first wave of COVID-19 pandemic. DESIGN: A descriptive longitudinal retrospective study. SETTING: This study was conducted in Internal Medicine Units in Salamanca University Hospital Complex, a tertiary hospital in the Salamanca province, Spain. PARTICIPANTS: All inpatients ≥18-year-old admitted from March 1, 2020 to June 1, 2020 for more than 24 hours in the Internal Medicine Units with one or more episodes of PIs. RESULTS: A total of 101 inpatients and 171 episodes were studied. The prevalence of PI episodes was 6% and the cumulative incidence was 2.9% during the first-wave of COVID-19. Risk of acute wounds was four times higher in the COVID-19 patient group (p<0.001). Most common locations were sacrum and heels. Among hospital acquired pressure injuries a significant association was observed between arterial hypertension and diabetes mellitus in patients with COVID-19 diagnosis. CONCLUSION: During the first wave of COVID-19, COVID-19 patients tend to present a higher number of acute wounds, mainly of hospital origin, compared to the profile of the non-COVID group. Diabetes mellitus and arterial hypertension were identified as main associated comorbidities in patients with COVID-19 diagnosis.

Myostatin and insulin-like growth factor-1 in hypertensive heart disease: a prospective study in human heart donors.

OBJECTIVE: The physiopathological mechanisms implicated in hypertensive heart disease are multi-factorial, including myocyte hypertrophy, apoptosis and myocardial remodelling. In this process, some hormonal and local growth factors have a regulatory influence. The aim of this study was to evaluate the potential role of myostatin and insulin-like growth factor-1 (IGF-1) myocardial expression in the development of hypertensive-induced cardiac damage. METHODS: Samples of human myocardium tissue from organ donors were prospectively collected and classified according to the presence of hypertension, alcohol consumption, other causes of myocardial damage and the presence of structural cardiomyopathy (CMP). Myocardial samples were studied by immunohistochemistry and myostatin, and IGF-1 myocardial expression was evaluated in all the different groups of donors. Hypertensive donors were compared to other groups. RESULTS: A total of 66 heart samples from human donors were collected: 33 donors had no previous or present history of hypertension and 33 donors presented defined hypertension. Donors with hypertension presented higher myocyte cell and nuclear hypertrophy and showed similar myostatin myocardial expression as controls, but lower IGF-1 myocardial expression. Myostatin expression was significantly higher in hypertensive donors with CMP compared to non-hypertensive healthy donors. The presence of CMP of diverse origin (alcoholic, valve and coronary) also significantly increased myostatin myocardial expression. CONCLUSION: The presence of hypertension significantly decreases IGF-1 myocardial expression. Myostatin myocardial expression increases in the presence of structural CMP either of hypertensive or other origin. These effects open the possibility of modulating hypertensive-induced cardiac damage.

Insulin-like growth factor 1 myocardial expression decreases in chronic alcohol consumption.

BACKGROUND: Alcoholic cardiomyopathy (CMP) is one of the major complications of chronic excessive alcohol consumption. The pathogenic mechanisms implicated are diverse, inducing functional and structural changes in the myocardium. Insulin-like Growth Factor 1 (IGF-1) plays an important role in modulating the cell cycle, and helps the differentiation and proliferation of cardiac tissue inhibiting apoptosis. Experimental studies have suggested the role of IGF-1 in alcohol-induced cardiac damage. The aim of the present study was to determine the effect of chronic alcohol consumption on IGF-1 myocardial expression and to compare this expression in cases of hypertension and other cardiac diseases. METHODS: We studied heart samples from human organ donors: 10 healthy donors, 16 with hypertension, 23 with chronic alcohol consumption and 7 with other causes of cardiac disease. IGF-1 myocardial expression was evaluated with a specific immunohistochemistry assay using a semi-quantitative method. RESULTS: A significant decrease in IGF-1 myocardial expression was observed comparing all the cases included with control donors. This decrease in IGF-1 myocardial expression was significantly lower in the group of donors with chronic alcohol consumption compared to controls. On group evaluation according to the presence of CMP, donors with chronic alcohol consumption without CMP presented significantly lower IGF-1 expression than controls, whereas donors with chronic alcohol consumption with CMP showed a downward trend without achieving significance. CONCLUSIONS: Chronic alcohol consumption significantly reduces IGF-1 myocardial expression. This decrease induced by alcohol is partially compensated in the presence of structural myocardial damage.

Increased myostatin activity and decreased myocyte proliferation in chronic alcoholic cardiomyopathy.

BACKGROUND: Apoptosis mediates in alcohol-induced heart damage leading to cardiomyopathy (CMP). Myocyte proliferation may compensate for myocyte loss. Myostatin is upregulated after cardiac damage and by alcohol consumption thereby decreasing myocyte renewal. We assess the potential role of alcohol in inducing myocyte apoptosis as well as in inhibiting myocyte proliferation. METHODS: Heart samples were obtained from organ donors, including 22 high alcohol consumers, 22 with hypertension, 8 with other causes of CMP, and 10 healthy donors. Evaluation included medical record with data on daily, recent and lifetime ethanol consumption, chest X-ray, left ventricular (LV) function assessed by two-dimensional echocardiography, and LV histology and immunohistochemistry. Apoptosis was evaluated by TUNEL, BAX, and BCL-2 assays. Myocyte proliferation was evaluated with Ki-67 assay. Myostatin activity was measured with a specific immunohistochemical assay. CMP was assessed by functional and histological criteria. RESULTS: Alcoholic and hypertensive donors with CMP showed higher apoptotic indices than did their partners without CMP. Myostatin activity was higher in alcoholics than in controls, mainly in those with CMP. The increase in myostatin expression in alcoholic CMP was higher than in other groups. The Ki-67 proliferation index increased in all groups with CMP compared to those without CMP, with alcoholics showing a lower increase in this proliferation response. CONCLUSIONS: Alcohol produces cardiac myocyte loss through apoptosis but also partially inhibits myocyte proliferation through myostatin up-regulation. The final result may suppose an imbalance in myocyte homeostasis, with a net loss in total ventricular myocyte mass and progressive ventricular dysfunction.

Down-regulation of adhesion molecules and other inflammatory biomarkers after moderate wine consumption in healthy women: a randomized trial.

BACKGROUND: Moderate alcohol consumption is cardioprotective. The mechanism for this beneficial effect might be reduced inflammatory responses, as suggested by prospective studies and small clinical trials in men. No studies have evaluated the antiinflammatory effects of wine in women. OBJECTIVE: We investigated whether low-dose intake of white and red wines has differential effects on inflammatory markers in women. DESIGN: In a crossover study, we randomly assigned 35 healthy women to two 4-wk periods of 20 g ethanol/d as white or red wine, preceded by two 4-wk washout periods. Before and after interventions, we measured serum lipids, circulating inflammatory biomarkers, cellular adhesion molecules (CAMs), and adhesion of monocytes to stimulated endothelial cells. RESULTS: HDL cholesterol increased, and the serum concentrations of high-sensitivity C-reactive protein, intercellular adhesion molecule-1, CD40L, and interleukin-6 decreased after either wine (P < 0.01, all). Vascular CAM-1 and E-selectin decreased (P < 0.01) only after red wine. CAM expression by mononuclear cells was blunted after either wine, with a greater suppressant effect of red wine. Enhanced adhesion of monocytes to stimulated endothelial cells was reduced by 51% (95% CI: -57%, -45%) after white wine and by 89% (95% CI: -96%, -82%) after red wine (P = 0.01 for between-wine differences). CONCLUSIONS: Moderate wine consumption is associated with beneficial effects on various inflammatory pathways related to endothelial activation in women. Probably because of its higher polyphenol content, red wine shows superior antiinflammatory effects than does white wine. Reducing low-grade inflammation and endothelial activation may be another potential mechanism by which alcoholic beverages exert their cardioprotective effect.

Inflammatory markers of atherosclerosis are decreased after moderate consumption of cava (sparkling wine) in men with low cardiovascular risk.

Atherosclerosis is considered a low-grade inflammatory disease. Polyphenol-rich alcoholic beverages (red wine) have shown a more pronounced antiinflammatory effect than polyphenol-free alcoholic beverages (gin). However, no studies to our knowledge have evaluated the antiinflammatory effects of alcoholic beverages with medium-level polyphenol content such as cava (sparkling wine). We enrolled 20 healthy men (aged 34 +/- 9 y) in a randomized crossover study to receive 30 g ethanol/d as cava or gin for 28 d. Before both interventions, subjects abstained from alcohol for 2 wk. Inflammatory biomarkers of atherosclerosis and expression of adhesion molecules on peripheral leukocytes were measured before and after each intervention. Likewise, dietary intake and exercise were also evaluated. Expression of lymphocyte function-associated antigen-1 (LFA-1), very late activation antigen-4 (VLA-4), Sialyl-Lewis(x) (SLe(x)), and CD40 on monocytes decreased after cava intake (all P < 0.05), whereas only SLe(x) was reduced after gin intake (P = 0.036). Circulating markers of atherosclerosis including vascular cell adhesion molecule-1, E-selectin, and P-selectin decreased after both interventions (all P < 0.05). High-sensitivity C-reactive protein, intercellular adhesion molecule-1 (ICAM-1), IL-6, monocyte chemoattractant protein-1 (MCP-1), and CD40L were diminished only after cava intake (all P < 0.05). The effects of cava on circulating CD40L, ICAM-1, and MCP-1, and monocyte surface expression of CD40, LFA-1, and VLA-4 were greater than those of gin (all P < 0.05). In conclusion, both cava and gin showed antiinflammatory properties; however, cava had a greater protective effect, probably due its polyphenol content.

Decreased tumor necrosis factor-induced adhesion of human monocytes to endothelial cells after moderate alcohol consumption.

BACKGROUND: Moderate alcohol consumption protects against ischemic heart disease, possibly through an antiinflammatory effect. However, little is known about the mechanisms by which alcohol may interfere in the development of atherosclerosis. OBJECTIVE: We analyzed the effects of 2 alcoholic beverages with high (red wine) or low (gin) polyphenolic content on human monocyte adhesion to an endothelial cell line (Ea.hy926). DESIGN: This was a randomized, crossover trial with 8 healthy men. After a washout period, the subjects received 30 g ethanol/d as red wine or gin for 28 d. Before and after each intervention, a dietary survey and laboratory analysis were performed. Adhesion of human monocytes to endothelial cells was measured in basal and stimulated [by tumor necrosis factor alpha (TNF-alpha)] conditions. Adhesion molecules involved in monocyte-endothelium interactions were determined on the cell surface. RESULTS: The mean expression of very late activation antigen 4 on monocytes significantly decreased after red wine intake [by 18% (95% CI: 33%, 3%); P = 0.022]. Monocyte adhesion significantly increased after TNF-alpha stimulation of endothelial cells. This increase, however, was 39% less (95% CI: 48%, 35%; P = 0.049) after gin intake than after the respective washout period and was nearly abolished by red wine intake [96% less than after the respective washout period (95% CI: 142%, 76%); P < 0.001]. The reduction after red wine intake was significantly different from that after gin intake (P = 0.014). CONCLUSIONS: TNF-alpha-induced adhesion of monocytes to endothelial cells was virtually abolished after red wine consumption but was only partially reduced after gin consumption. This effect may be due to the down-regulation of adhesion molecules on the monocyte surface.

Different effects of red wine and gin consumption on inflammatory biomarkers of atherosclerosis: a prospective randomized crossover trial. Effects of wine on inflammatory markers.

BACKGROUND: No intervention studies have explored the anti-inflammatory effects of different alcoholic beverages on markers of atherosclerosis. We embarked on a randomized, crossover, single-blinded trial to evaluate the effects of wine and gin on inflammatory biomarkers of atherosclerosis. METHODS AND RESULTS: Forty healthy men (mean age, 37.6 years) consumed 30 g ethanol per day as either wine or gin for 28 days. Before and after each intervention, we measured the expression of lymphocyte function-associated antigen 1 (LFA-1), Mac-1, very late activation antigen 4 (VLA-4), and monocyte chemoattractant protein (MCP-1) in monocytes, as well as the soluble vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), interleukin-1alpha (IL-1alpha), C-reactive protein (hs-CRP) and fibrinogen. After either gin or wine consumption, plasma fibrinogen decreased by 5 and 9%, respectively, and cytokine IL-1alpha by 23 and 21%. The expression of LFA-1 (-27%), Mac-1 (-27%), VLA-4 (-32%) and MCP-1 (-46%) decreased significantly after wine, but not after gin. Wine reduced the serum concentrations of hs-CRP (-21%), VCAM-1 (-17%) and ICAM-1 (-9%). CONCLUSIONS: Both wine and gin showed anti-inflammatory effects by reducing plasma fibrinogen and IL-1alpha levels. However, wine had the additional effect of decreasing hs-CRP, as well as monocyte and endothelial adhesion molecules.

Effects of alcohol withdrawal on 24 hour ambulatory blood pressure among alcohol-dependent patients.

BACKGROUND: Although epidemiologic studies have reported an association between alcohol intake and high blood pressure (BP), the results of intervention studies have shown inconsistent results. We embarked on a study to determine whether different subgroups of alcohol-dependent patients may be identified in relation to the effect of alcohol on BP. METHODS: Fifty alcohol-dependent men (mean age, 41.4 years) received 0.4 g of ethanol per kilogram of body weight every 4 hr in 200 ml of orange juice during 24 hr and the same amount of orange juice without ethanol during another 24 hr. Twenty-four hour ambulatory BP monitoring was performed during ethanol and orange juice intakes, as was hormonal and biochemical analysis. RESULTS: Thirty-five (75%) alcohol-dependent men were normotensive and 15 (30%) hypertensive. Eighteen (51%) normotensive and 12 (80%) hypertensive subjects showed a significant decrease in 24 hr mean BP after ethanol withdrawal (mean decrease of 8.4 mm Hg [95% confidence interval, -11.2 to -5.7] and 12.5 mm Hg [confidence interval, -16.2 to -8.8], respectively) and were considered as sensitive to alcohol. The remaining alcohol-dependent subjects were considered as resistant to alcohol. Normotensive subjects sensitive to ethanol showed a significantly greater left ventricular mass and a significantly lower ejection fraction than those normotensive patients whose BP did not change after ethanol withdrawal (both p < 0.01). CONCLUSIONS: More than three fourths of the hypertensive and more than half of the normotensive alcohol-dependent patients showed sensitivity to the pressor effects of ethanol. Impairment also was observed in heart function in normotensive patients sensitive to the pressor effects of ethanol.
