Effect of three different exercise trainings on functional capacity in early stage severe burn patients: A randomized controlled trial.

BACKGROUND: This study investigated the effects of three different exercise protocols on functional capacity in early-stage burn patients. METHODS: A total of 25 patients hospitalized in the Burn Center (wards and intensive care unit) were included in the study. The individuals were divided into three groups by covariate adaptive randomization according to burn percentage and type: 1 - standard treatment, 2 - standard treatment + aerobic exercise training, 3 - standard treatment + combined exercise (aerobic and resistance) determined by metabolic status. Individuals were evaluated weekly for six weeks from the first day of hospitalization using the 6-minute walk test, physiological cost index, and Medical Research Council muscle-strength measurements to assess functional capacity. A portable metabolism tracker device measured the metabolic status of all patients. RESULTS: Aerobic exercises and combined exercise (aerobic and resistance), when added to standard treatment and determined by metabolic status, were more effective in enhancing functional capacity than standard treatment alone (p<0.05). Patients performing the combined exercise (aerobic and resistance) showed faster improvement in functional capacity determined according to metabolic status than those in the other two groups (p<0.05). CONCLUSION: Aerobic exercises, when added to standard treatment and combined with aerobic and resistance exercises based on metabolic status, are more effective at improving functional capacity than standard treatment alone. Further controlled studies are required to explore the potential long-term benefits of this approach.

Effect of aerobic exercise on neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and lymphocyte-monocyte ratio in burn patients: A randomized controlled trial.

BACKGROUND: This study aimed to investigate the effects of aerobic exercises in addition to standard treatment on parameters such as neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio (LMR) in patients with burns. METHODS: A total of 31 hospitalized patients included in the study were divided into two groups using covariate adaptive randomization method according to burn percentage and burn type (1st:standard treatment, 2nd: standard treatment + aerobic training). NLR, PLR, and LMR were evaluated for 5 weeks in all groups. Independent samples t-test and Mann-Whitney U test were used to examine differences between the two groups. For comparing more than two groups, Friedman's test was used for non-normally distributed variables and Bonferroni test was used as the post hoc pairwise comparison method. RESULTS: Intragroup comparison of individuals in group 1 showed that the NLR values on days 7 and 14 were significantly higher than those on days 28 and 35 (p < 0.05). Intragroup comparison of individuals in group 2 showed that the NLR values on days 1, 7, and 14 were significantly higher than those on days 21 and 35. Additionally, the NLR values on day 14 were higher than those on day 28. Individuals in group 1 showed a significant increase in PLR values each week (p < 0.05). CONCLUSIONS: The addition of aerobic training to standard treatment in patients with burns may be more effective in improving inflammation markers such as NLR, PLR, and LMR.

Machine learning models for early prediction of mortality risk in patients with burns: A single center experience.

Mortality rate is considered as the most important outcome measure for assessing the severity of burn injury. A scale or model that accurately predicts burn mortality can be useful to determine the clinical course of burn injuries, discuss treatment options and rehabilitation with patients and their families, and evaluate novel, innovative interventions for the injuries. This study aimed to use machine learning models to predict the mortality risk of patients with burns after their first admission to the center and to compare the performances of these models. Overall, 1064 patients hospitalized in burn intensive care and burn service units between 2016 and 2022 were included in the study. In total, 40 parameters, including demographic characteristics and biochemical parameters of all patients, were analyzed in the study. Furthermore, the dataset was randomly divided into two clusters with 70% of the data used for artificial neural networks (ANNs) training and 30% for model success testing. The ANN model proposed in this study showed high success across all machine learning methods tried in different variants, with an accuracy of 95.92% in the test set. Machine learning models can be used to predict the mortality risk of patients with burns. This study may help validate the use of machine learning models for applications in clinical practice. Conducting multicenter studies will further contribute to the literature.

Investigation of glucose, serum insulin levels, and insulin resistance in patients with major burn: a retrospective cross-sectional study.

BACKGROUND: Many studies have reported that insulin resistance (IR) is present and persistent in patients with major burns; however, the evidence remains insufficient. This study was planned to investigate insulin levels and IR in the early post-traumatic period in patients with major burns and to determine the prevalence of IR after burn injury. METHODS: This study included 68 patients. These patients were followed up once a week for 4 weeks after hospitalization. In the follow-up examinations, demographic and burn injury characteristics; HbA1c, procalcitonin serum glucose, and insulin levels; and IR were evaluated. RESULTS: IR was seen in some weeks only in 25 of the 68 patients included in the study. Among all patients, IR was determined in only 11 (16.17%) patients from the 1st day of hospitalization until discharge. Patients with and without IR were evaluated as 2 groups, and their biochemical parameters were compared, and no significant difference was found between glucose and procalcitonin levels (P>0.05). Glucose levels were >100 mg/dL in the first few weeks in all patients who were followed up; however, they returned to the normal range in the following weeks. CONCLUSION: In patients with IR, there was insufficient evidence to conclude that the condition persists. We believe that the HOMA-IR value is not directly related to burn injuries and that other additional pathologies may cause it during treatment.

A remarkable point for evaluating the severity of burns: Thiol-disulfide profile.

AIM: The objective of this study was to examine the thiol-disulfide profile tests in patients suffering from burn injuries. METHODS: This case-control study comprised 48 patients with thermal burn injuries and 61 healthy individuals. Thiol-disulfide tests were conducted in both groups, and also, the changes of thiol-disulfide parameters were analyzed at zero time and on days 3, 7, 15, and 30 of the admission in patients with burn injuries. RESULTS: The patients had significantly decreased native and total thiol levels and native thiol/total thiol ratios, and significantly increased disulfide/native thiol and disulfide/total thiol ratios compared to control individuals (p<0.001 for all). The variations of native thiol levels, total thiol levels, and disulfide/native thiol ratios were significantly different over time in patients with burn injuries (p<0.001, p<0.001, p<0.05, respectively). There were strong associations with the clinical parameters and thiol-disulfide profile tests (p<0.05 for all). CONCLUSION: There was a metabolic disturbance of the thiol-disulfide system among patients with burn injuries. The courses of thiol-disulfide variables in time overlapped with the burn mechanism. Strong associations provide that thiol-disulfide homeostasis might be a notable key for evaluating the severity of burns and predicting the survival.

The effects of early physiotherapy on biochemical parameters in major burn patients: A burn center's experience.

BACKGROUND: This study sets out to investigate the effects of early physiotherapy on biochemical parameters in major burn patients. METHODS: Ten women (50%) and 10 men (50%) aged 21-47 years old were included in this study. Participants were divided into two groups: the first group was the treatment group and the second group was the control group. In the treatment group, patients were admitted to the physiotherapy programme from the first day they have been hospitalised, in addition to their routine treatment (e.g. medical, surgery), for four days per week. The physiotherapy programme consisted of parameters, such as early mobilisation and ambulatory training, chest physiotherapy, and both active and passive normal joint movement exercises. The days of treatment were determined as of Tuesday, Wednesday, Thursday and Friday. Patients could not be treated on a Monday because that was surgery day. The control group consisted of patients who could not receive physiotherapy due to various reasons. All patients included in this study were evaluated weekly for six weeks after admission to the hospital. Parameters, such as demographic information, characteristics of burn injury, C-reactive protein, fibronectin, transferrin and prealbumin, were evaluated. RESULTS: When the results obtained in this study were considered, there was a significant difference in favour of the treatment group for all biochemical parameters (p<0.05). From the second week, a significant increase was observed in prealbumin values in the treatment group (p<0.05). A significant increase was observed in fibronectin after the fourth week (p<0.05). CONCLUSION: We believe that early physiotherapy should be included in the treatment in major burns. Early physiotherapy may reduce the effects of hypermetabolic response after major burns. There is a need for multi-centered and broader studies.

Our 18-month experience at a new burn center in Gaziantep, Turkey.

BACKGROUND: This study is a retrospective analysis of 411 cases admitted to Cengiz Gökcek State Hospital Burn Center from 1 May 2007 to 10 October 2008. METHODS: Through an electronic database of medical records of the burn center, all patients admitted to the center were traced. With respect to the numbers of burns according to sex, 35.7% (147) of the cases were female and 64.3% (264) were male. RESULTS: For total burn surface area (TBSA) of 20-35%, the hospital stays for electric, flame and scald burns were 28, 18 and 12 days, respectively. For TBSA of 35-50%, electric burns resulted in a mean stay of 44 days, followed by chemical burns (33 days), flame (31 days), and scald (22 days). For TBSA over 50%, electric and scald burns resulted in hospital stays of > or =40 days. Case fatality was 5.6% (23 patients). 1.2% of the study group experienced at least one episode of epilepsy during treatment. Six cases had acute renal failure that responded to hemofiltration during treatment. Eight cases, which were flame burns, also had inhalation injury, and four of these cases required mechanical ventilation. CONCLUSION: Members of the burn care team not only carry a heavy workload in the treatment of burn victims, we believe they also have the responsibility of recording and publishing their own data to increase the overall knowledge related with the subject, which will guide future studies.

Primary leiomyoma of the thyroid gland.

Primary thyroid leiomyomas are rare, and only four cases have been reported to date. This is a report of an additional case of primary thyroid leiomyoma in a 40-year-old male who was admitted with a painless swelling in the right thyroid lobe and underwent subtotal thyroidectomy. The surgical specimen showed a well-circumscribed, greyish-white solid nodule. Histologically, the tumour was composed of spindle cells with blunt-ended nuclei that were arranged with short intersecting bundles. Immunohistochemical staining revealed reactivity with smooth muscle actin, vimentin and desmin. Histopathologic and immunohistochemical assessments produced the diagnosis of thyroid leiomyoma. Although primary thyroid leiomyoma is rare, it should be considered in the differential diagnosis of a cold thyroid nodule.
