Thermal Injuries

Abstract Introduction Thermal injuries represent a major health problem. Biomarkers capable of predicting burned patients outcomes are missing. Certain parameters of complete blood count (CBC) such as red cell distribution width (RDW) and mean platelet volume (MPV), as well as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and RDW-to-platelet ratio (RPR) have been associated with inflammatory status and outcome in diverse medical conditions. The aim of this study was to describe the evolution pattern of these parameters in adult burned patients. Methods Adult burned patients admitted to the National Burn Center of a University Hospital between May 2017 and March 2018 were included. Patients characteristics and outcomes were recorded, as well as CBC parameters on days 1, 3, 5 and 7 after thermal injury. Results Eighty-eight patients were included. Total body surface area burned was 14 [7–23] %, and mortality was 15%. Non-survivors presented higher RDW (days 3, 5 and 7; P < 0.01) and MPV (days 3 and 7; P < 0.01). NLR decreased after admission in all patients (P < 0.01), but was higher in non-survivors compared to survivors on days 1 and 7 (P < 0.01). On day 3, PLR was higher in survivors than in non-survivors (P < 0.05). In deceased patients, RPR was significantly higher on days 3, 5 and 7 (P < 0.01). There was a significant correlation between NLR on admission and burn extension and severity. Kaplan-Meier analysis revealed that NLR, PLR and RPR could identify patients with increased mortality. Conclusions Basic CBC parameters and derived indices could be useful as biomarkers to determine prognosis in adults with thermal injuries. Applicability of Research to Practice The study allowed us to identify basic CBC parameters and indices that behave differently in survivors and non-survivors. Interestingly, the CBC profile that differentiates survivors and non-survivors varies at each time point. A particular combination of CBC parameters might be used as a prognostic indicator depending on evolution time since thermal injury.

Abstract Certain parameters of complete blood count (CBC) such as red cell distribution width (RDW) and mean platelet volume, as well as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and RDW-to-platelet ratio (RPR) have been associated with inflammatory status and outcome in diverse medical conditions. The aim of this study was to describe the evolution pattern of these parameters in adult burned patients. Adult burned patients admitted to the National Burn Center in Uruguay between May 2017 and February 2018 (discovery cohort) and between March 2018 and August 2019 (validation cohort) were included. Patients’ characteristics and outcomes were recorded, as well as CBC parameters on days 1, 3, 5, and 7 after thermal injury. Eighty-eight patients were included in the discovery cohort. Total body surface area burned was 14 [7–23]% and mortality was 15%. Nonsurvivors presented higher RDW and mean platelet volume (P < .01). NLR decreased after admission in all patients (P < .01), but was higher in nonsurvivors (P < .01). Deceased patients also presented higher RPR on days 3, 5, and 7 (P < .001). On the contrary, PLR was reduced in nonsurvivors (P < .05). There was a significant correlation between NLR on admission and burn extension and severity. Kaplan–Meier analysis revealed that NLR, PLR, and RPR could identify patients with increased mortality. These findings were confirmed in the validation cohort (n = 95). Basic CBC parameters and derived indices could be useful as biomarkers to determine prognosis in adults with thermal injuries.

Acute appendicitis is one of the most common causes of acute abdominal diseases seen between the ages of 10 and 19, mostly seen in males. The lifetime risk of developing acute appendicitis is 8.6% for males and 6.7% for females. We aimed to investigate the efficacy of the complete blood count parameters, C-reactive protein, and Lymphocyte-C-reactive Protein Ratio laboratory tests in the diagnosis of acute appendicitis, as well as their relationship with appendix diameter. We retrospectively examined all patients who underwent appendectomy between 1 January 2012 and 30 June 2019 in the General Surgery Clinic of Gaziosmanpasa University Faculty of Medicine. Laboratory tests, imaging findings, age, and gender were recorded. Lymphoid hyperplasia is considered as normal appendix—in other words, as negative appendicitis. The distribution of Lymphoid hyperplasia and appendicitis rates were statistically different in the groups formed according to appendix diameter (≤6 and >6 mm) (p < 0.001). We found a significant correlation between appendix diameter and WBC (White blood count), Lymphocyte, Neutrophil, RDW(Red blood cell distribution width), NLR(Neutrophil to lymphocyte ratio), and PLT/L (Platelet to lymphocyte ratio), MPV (Mean platelet volume) and RDW were significantly different in patients with an appendix diameter of ≤6 mm (p = 0.007, p = 0.006, respectively). WBC, Neutrophil, PDW, and NLR values were significantly different between appendicitis and hyperplasia groups in patients with an appendix diameter of >6 mm. The sensitivity of the NLR score (cutoff = 2.6057) in the diagnosis of appendicitis was 86.1% and selectivity was 50% in these patients. Complete blood count parameters evaluation with the clinical findings revealed that NLR is an important parameter that may help the diagnosis of acute appendicitis with an appendix diameter of >6 mm. In patients whose pathological results indicated acute appendicitis but who had a diameter of ≤6 mm, we found an elevated MPV and low RDW values.

This article discusses the relationship between parameters of complete blood count (CBC) and cardiovascular diseases (CVD). The main advantages of CBC over other methods of CVD diagnostics are low cost and wide availability. At the same time, the low specificity of CBC is an important disadvantage, limiting its diagnostic value.After analyzing the results of numerous clinical studies, we concluded that the most important CBC are red cell distribution width, mean platelet volume, total leukocyte count, neutrophil to lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte to high-density lipoprotein ratio. We discuss the diagnostic value of each of the above indicators in CVD. Careful attention to these parameters by clinicians can, to a certain extent, improve the therapeutic and diagnostic process in patients with CVD.

AbstractObjectivesTo evaluate the relationship between Coronavirus Disease 2019 (COVID-19) in pregnancy and adverse perinatal outcomes. The secondary aim is to analyze the diagnostic value of hematologic parameters in COVID-19 complicated pregnancies.MethodsThe current study is conducted in a high volume tertiary obstetrics center burdened by COVID-19 pandemics, in Turkey. In this cohort study, perinatal outcomes and complete blood count indices performed at the time of admission of 39 pregnancies (Study group) complicated by COVID-19 were compared with 69 uncomplicated pregnancies (Control group).ResultsThere was no significant difference between the obstetric and neonatal outcomes of pregnancies with COVID-19 compared to data of healthy pregnancies, except the increased C-section rate (p=0.026). Monocyte count, red cell distribution width (RDW), neutrophil/lymphocyte ratio (NLR), and monocyte/lymphocyte ratio (MLR) were significantly increased (p<0.0001, p=0.009, p=0.043, p<0.0001, respectively) whereas the MPV and plateletcrit were significantly decreased (p=0.001, p=0.008) in pregnants with COVID-19. ROC analysis revealed that the optimal cut-off value for MLR was 0.354 which indicated 96.7% specificity and 59.5% sensitivity in diagnosis of pregnant women with COVID-19. A strong positive correlation was found between the MLR and the presence of cough symptom (r=41.4, p=<0.0001).ConclusionsThe study revealed that, pregnancies complicated by COVID-19 is not related with adverse perinatal outcomes. MLR may serve as a supportive diagnostic parameter together with the Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) in assessment of COVID-19 in pregnant cohort.

There have been few studies reported with conflicting results in the use of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), redcell-distribution-width (RDW), etc. for predicting prognosis and differential diagnosis of adrenal tumors. The aim of this study is to investigate the role of inflammatory markers through a complete blood count, which is an easy access low-cost method, for the differential diagnosis of adrenocortical adenoma (ACA), adrenocortical carcinoma (ACC), and pheochromocytoma. The data of patients who underwent adrenalectomy between the years of 2010–2020 were retrospectively analyzed. Systemic hematologic inflammatory markers based on a complete blood count such as neutrophil ratio (NR), lymphocyte ratio (LR), NLR, PLR, RDW, mean platelet volume (MPV), and maximum tumor diameter (MTD) were compared between the groups. A statistically significant difference was found between the three groups in terms of PLR, RDW, and MTD. With post-hoc tests, a statistically significant difference was found in PLR and MTD between the ACA and ACC groups. A statistically significant difference was found between the ACA and pheochromocytoma groups in PLR and RDW values. In conclusion, it could be possible to plan a more accurate medical and surgical approach using PLR and RDW, which are easily calculated through an easy access low-cost method such as a complete blood count, together with MTD in the differential diagnosis of ACC, ACA, and pheochromocytoma.

SUMMARY OBJECTIVE To compare the complete blood counts, namely the plateletcrit (PCT) and Platelet-To-Lymphocyte Ratio (PLR) of healthy subjects and those with morbid obesity in the young population. METHODS We included 45 patients with morbid obesity (body mass index -BMI - greater than or equal to 45 kg/m2) and 45 healthy subjects (BMI less than or equal to 25 kg/m2) in our study. Blood samples were obtained from the participants following a 12-hour fasting period. Then we evaluated the levels of hemoglobin (Hb), hematocrit (HCT), red cell distribution width (RDW), mean platelet volume (MPV), white blood cell (WBC), PLR, platelet counts, and PCT in the complete blood count. RESULTS The morbid obesity group had significantly higher platelet counts and PCT values (p<0.001), and PLR values (p=0.033). The value of WBC was also higher in the obese group (p=0.001). MPV was lower in the obesity group but not statistically significant (p=0.815). No significant difference was found between hemoglobin and hematocrit values in these groups; but RDW valuewere higher and statistically significant in the obese group (p=0.001). CONCLUSION PLR or PCT may be more useful as a marker in determining an increased thrombotic state and inflammatory response in morbid obesity.

Red Blood Cell Distribution

Aim: Anemia is a public health problem worldwide. Cost effectiveness and efficient use of resources are vitally important. Red blood cell distribution width, which can be obtained from a standard complete blood count, is a measure of the variability in size of circulating erythrocytes. The present study was performed to investigate whether red blood cell distribution width can be used to predict response to iron therapy. Methods: This study was conducted in 50 patients admitted to hematology and family medicine clinics. Complete blood count and reticulocyte count were determined on day 5; complete blood count was examined 1 month after commencement of therapy. Results: Statistically significant differences were detected between hemoglobin levels and red blood cell distribution width values at the time of diagnosis and on day 5 and after 1 month of therapy. A significant positive correlation was found between the increase in red blood cell distribution width and the increase in hemoglobin. Conclusion: Red blood cell distribution width may be used in place of reticulocyte count to predict response to iron therapy. Red blood cell distribution width is the best biomarker for this purpose as a component of complete blood count, and therefore it may be accepted as superior to reticulocyte count.

Abstract Electronic cigarettes are advertised as safer alternatives to traditional cigarettes yet cause serious injury. US burn centers have witnessed a rise in both inpatient and outpatient visits to treat thermal injuries related to their use. A multicenter retrospective chart review of American Burn Association burn registry data from 5 large burn centers was performed from January 2015 to July 2019 to identify patients with electronic cigarette-related injuries. A total of 127 patients were identified. Most sustained less than 10% total body surface area burns (mean 3.8%). Sixty-six percent sustained 2nd degree burns. Most patients (78%) were injured while using their device. Eighteen percent of patients reported spontaneous device combustion. Two patients were injured while changing their device battery, and two were injured modifying their device. Three percent were injured by second-hand mechanism. Burn injury was the most common injury pattern (100%), followed by blast injury (3.93%). Flame burns were the most common (70%) type of thermal injury; however, most patients sustained a combination-type injury secondary to multiple burn mechanisms. The most injured body region was the extremities. Silver sulfadiazine was the most common agent used in initial management of thermal injuries. Sixty-three percent of patients did not require surgery. Of the 36% requiring surgery, 43.4% required skin grafting. Multiple surgeries were uncommon. Our data recognizes electronic cigarette use as a public health problem with potential to cause thermal injury and secondary trauma. Most patients are treated on an inpatient basis although most patients treated on outpatient basis have good outcomes.

Background Obesity is a growing public health problem of rapidly increasing prevalence in developing countries. Chronic low-grade inflammation plays a key role in the pathophysiology of obesity. Blood count values and ratios have been used as markers of inflammatory diseases. These parameters may be useful to determine the severity of chronic inflammation in obese children. Objective To determine if red blood cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), mean platelet volume (MPV), platelet distribution width (PDW), and platelet-to-lymphocyte ratio (PLR) can be useful for determining the severity of chronic inflammation in obese children. Methods This observational, analytic study was conducted in obese adolescents aged 14-18 years at senior high schools in Manado, North Sulawesi, from July to September 2018. Students with congenital anomalies, autoimmune diseases, history of asthma, or malignancy were excluded. Pearson’s correlation was used to analyze for potential relationships between obesity and red blood cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), mean platelet volume (MPV), platelet distribution width (PDW), and platelet-to-lymphocyte ratio (PLR). Results There was a negative relationship between obesity and MPV, but it was not statistically significant (r=-0.006; P=0.485). There were positive, but not significant relationships between obesity and RDW (r=0.139; P=0.192), NLR (r=0.155; P=0.166), PDW (r=0.02; P=0.45), and PLR (r=0.146; P=0.181). Conclusion The RDW, NLR, MPV, PDW, and PLR values are not significantly associated with severity of obesity in adolescents.

Abstract Objective Missed abortion occurs in ∼ 15% of all clinical pregnancies. The pathogenesis is not clearly known. However, defective placentation resulting in maternal systemic inflammatory response is considered responsible for missed abortion. Platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) are increasingly cited parameters of inflammation in the literature. However, no study evaluated the PLR and NLR rates in missed abortions so far. The aim of the present study is to investigate whether complete blood count (CBC) inflammatory parameters such as NLR and PLR are increased in patients with missed abortion. Methods Medical records of 40 pregnant women whose gestation ended in missed abortion at between 6 and14 weeks of gestation and of 40 healthy pregnant women were collected and compared retrospectively. The groups were compared regarding hemoglobin, hematocrit, platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), PLR and NLR. Results Platelet distribution width, NLR and PLR values were higher in the missed abortion group compared with the healthy pregnant women group (rates are p = 0.043; p = 0.038; and p = 0.010, respectively). Hematocrit, MPV, and lymphocyte values were found to be lower in the missed abortion group compared with the healthy pregnant women group (p = 0.027, p = 0.044 and p = 0.025, respectively). Conclusion The PDW, NLR and PLR values of the missed abortion group were reported high; and MPV values were reported low in the present study. These findings may help to speculate a defective placentation in the pathogenesis of missed abortion.
