Patients in intensive care units (ICUs) frequently require mechanical ventilation, with approximately half needing invasive ventilation through an orotracheal tube. For these patients, gastric tube (GT) insertion is routinely performed to administer nutrition and medications or to drain gastric contents. The insertion route (oral or nasal) may affect the incidence of ventilator-associated pneumonia (VAP), a significant ICU care complication. This study aims to compare the impact of oral versus nasal GT insertion on the incidence of VAP in intubated ICU patients.
The SONG trial (NCT 05915663) is a multicentre, open-label, two-period, two-intervention, cluster randomised crossover superiority trial. 16 French ICUs will participate. ICUs will be randomised to periods of nasogastric or orogastric tube placement. The trial includes a practice standardisation period, followed by two 12-month inclusion periods separated by a monitoring and washout period. The primary endpoint is the incidence rate of VAP at day 28, confirmed by three independent physicians. Secondary endpoints include the ease of GT insertion, measured by the number of attempts.
This study received approval from a central ethical review board on 12 April 2024 (CPP Sud-est VI, registration number 23.00943.000175). Patients are included after informed consent or, when not possible, from next of kin. If none are available, the investigator will proceed with emergency inclusion, following French law. When consent is initially obtained from the next of kin or through emergency inclusion, the investigator will seek consent from the patient as soon as possible. Data will be anonymised and patient confidentiality maintained. Results will be published in peer-reviewed journals and presented at scientific meetings.
Radiotherapy is recommended for G2-G3 large soft tissue sarcoma in association with radical wide excision in order to improve the local control of disease, but side-effects may develop early after radiation invalidating wound healing. We retrospective evaluated short- and long-term clinically relevant outcomes after surgery of limb STS with or without radiotherapy. All 243 patients with limb STS treated at the Veneto Institute Oncology (Padua, Italy) in 2015–2022 were retrospectively included. Outcome measures were short- and long-term wound complications, length of hospital stay and outpatient care time. Multivariable analyses were performed using linear regression models and logistic regression models. Overall, 87 patients received neoadjuvant radiotherapy, 64 received adjuvant radiotherapy and 92 underwent surgery alone. At short-term, multivariable analysis identified neoadjuvant radiotherapy as a risk factor for prolonged length of hospital stay (MD 6.4 days, 95%CI 3.9 to 9.0 days) and short-term wound complications (OR 3.45, 95%CI 1.82 to 6.62). At long-term, neoadjuvant radiotherapy was a risk factor for long-term wound complications (OR 4.87, 95%CI 2.48 to 9.84), and longer outpatient care time (MD 83 days, 95%CI 41 to 126 days); similarly, adjuvant radiotherapy was also a risk factor for long-term complications (OR 5.20, 95%CI 2.57 to 10.95) and longer outpatient care time (MD 62 days, 95%CI 19 to 106 days). Radiotherapy in limb STS was associated with impaired short- and long-term clinically relevant outcomes, potentially affecting quality of life and healthcare costs. Balancing with its well-known oncological benefits, new clinical strategies are needed to contain cutaneous radiogenic side effects. The use of negative pressure therapy can play a key role in the prevention of wound complications in oncological patients.

Vitamin D has been increasingly recognized for its potential role in modulating various health conditions, including diabetes and its complications. Despite growing evidence suggesting that adequate vitamin D levels may reduce the risk of developing type 2 diabetes and its associated microvascular complications, the precise nature of this relationship remains unclear. This study aims to elucidate the connection among vitamin D status, glycemic control, and microvascular complications in patients with type 2 diabetes, thereby highlighting the importance of vitamin D in diabetes management.This analytical cross-sectional study included 199 type 2 diabetic mellitus (T2DM) patients from the Jahrom city endocrinology clinic. Serum 25(OH)D levels were measured, and their microvascular complications (microalbuminuria, retinopathy, neuropathy, macroalbuminuria) and glycemic control (HbA1C) were measured and confirmed according to ADA guidelines and endocrinologist supervision. All analysis were done with SPSS software. The study enrolled 199 type 2 diabetic patients with a mean age of 56.79 ± 10.8 years, of which 63.3% were female and 57.3% had hypertension. The mean BMI was 28.91 kg/m², and 29.1% of participants had vitamin D deficiency. The prevalence of microvascular complications was 25.6% for retinopathy, 14.1% for neuropathy, and 40% for nephropathy. Vitamin D deficiency was notably higher among patients with retinopathy (37.25%), neuropathy (50%), and macroalbuminuria (56.25%). Patients with neuropathy and retinopathy had significantly lesser serum 25(OH)D concentrations compared to patients without these complications. There was a slight inverse correlation between vitamin D levels and both the urine albumin creatinine ratio (r = -0.175, p = 0.018) and HbA1C (r = -0.19, p = 0.007). Although the link between vitamin D levels and retinopathy was not statistically significant (η = 0.903, p = 0.68), the alteration in vitamin D levels was suggestively linked with neuropathy (η = 0.975, p

This paper seeks to enhance the performance of Mel Frequency Cepstral Coefficients (MFCCs) for detecting abnormal heart sounds. Heart sounds are first pre-processed to remove noise and then segmented into S1, systole, S2, and diastole intervals, with thirteen MFCCs estimated from each segment, yielding 52 MFCCs per beat. Finally, MFCCs are used for heart sound classification. For that purpose, a single classifier and an innovative ensemble classifier strategy are presented and compared. In the single classifier strategy, the MFCCs from nine consecutive beats are averaged to classify heart sounds by a single classifier (either a support vector machine (SVM), the k nearest neighbors (kNN), or a decision tree (DT)). Conversely, the ensemble classifier strategy employs nine classifiers (either nine SVMs, nine kNN classifiers, or nine DTs) to individually assess beats as normal or abnormal, with the overall classification based on the majority vote. Both methods were tested on a publicly available phonocardiogram database. The heart sound classification accuracy was 91.95% for the SVM, 91.9% for the kNN, and 87.33% for the DT in the single classifier strategy. Also, the accuracy was 93.59% for the SVM, 91.84% for the kNN, and 92.22% for the DT in the ensemble classifier strategy. Overall, the results demonstrated that MFCCs were more effective than other features, including time, time-frequency, and statistical features, evaluated in similar studies. In addition, the ensemble classifier strategy improved the accuracies of the DT and the SVM by 4.89% and 1.64%, implying that the averaging of MFCCs across multiple phonocardiogram beats in the single classifier strategy degraded the important cues that are required for detecting the abnormal heart sounds, and therefore should be avoided.
We evaluated the primary application of crushed prednisolone combined with hydrocolloid powder for clinically diagnosed peristomal pyoderma gangrenosum (PPG). We present our data on this cohort and follow-up of our previous patients. Of the 23 patients who were commenced on this regime, 18 healed (78%). Twenty-two patients commenced on this regime as the primary treatment for their PPG, and for one, it was a rescue remedy after failed conventional therapy. Four patients with significant medical comorbidities failed to heal and one had their stomal reversal surgery before being fully healed. The proposed treatment regime for PPG is demonstrated to be effective, inexpensive and able to be managed in the patient's usual home environment. In vitro drug release analysis was undertaken, and data are presented to provide further insights into the efficacy of this regime.
Evaluating complications and mortality risks in burn patients is crucial for effective treatment planning and improving survival rates. This study investigated the relationship between the serum vitamin D level and the clinical outcomes of adult burns patients. This was a prospective cohort of adult patients hospitalized due to thermal burns at a burn centre in the north of Iran. Based on the level of 25 hydroxyvitamin D measured upon admission, patients were divided into two groups of patients with sufficient 25 hydroxyvitamin D level and insufficient 25 hydroxyvitamin D level. Descriptive statistics were used for baseline demographics. Univariate analysis was conducted using Mann–Whitney U, Chi-square, independent samples, and Fisher's exact tests. A multivariate logistic regression was performed to adjust for the effects of confounding variables. Statistical analyses were conducted using SPSS 28.0 software. A total of 220 patients were included in the study. The average total body surface area burned was 30.52 ± 9.34. Patients with insufficient vitamin D levels had longer hospital stays (12.53 vs. 11.45) and longer stays in the intensive care unit (ICU) (3.32 vs. 2.40) than those with appropriate vitamin D levels. Participants with insufficient vitamin D levels exhibited a numerically higher incidence of infections than those with adequate levels (p < 0.05). The multivariate regression found that vitamin D deficiency levels were associated with increased infection rates and prolonged hospital stay. This study suggests that vitamin D deficiency is a significant risk factor for adverse clinical outcomes in burn patients. Further research is needed to confirm these associations and to explore potential interventions to optimize vitamin D status in this patient population.
Children's burns are a major public health concern due to their long-term physical, psychological, and social impacts, as well as their high financial burden. This study aimed to evaluate the effectiveness of a smartphone-based educational program on outcomes of children with severe burns. This study was designed as a double-blinded, randomized controlled trial (RCT) to test the effectiveness of a developed mobile application. A total of 93 participants were included in the final analysis. The participants were randomly assigned to either the intervention or control groups. Participants in both groups received usual self-care training at discharge, but those in the intervention group used an Android-based application for 2 months. The primary goal of the burn application was scar recovery, and the secondary goals were to increase child caregivers' satisfaction rate and decrease unplanned hospital readmissions. Data collection was conducted using valid and reliable questionnaires. Data were analysed using SPSS software. The study showed that the mobile application significantly affected the frequency of patient visits to the burn clinic and the satisfaction of caregivers of children with burns with the treatment process (p-value <0.05). Also, there was a significant relationship between the duration of application use and wound healing status ((p-value <0.001). These findings suggest that smartphone-based educational programs can be valuable for optimizing care for children with severe burns. Further research is warranted to explore the long-term impact of this intervention and its potential application in different healthcare settings.
Optimal management of burns begins with first aid from the first hours of injury. Adequate knowledge of how to perform first aid for burns can reduce the consequences of injury. Therefore, this study aims to determine the knowledge, attitude, and sources of information assessment towards burn First aid among people referred to a burn centre in the north of Iran. A questionnaire-based survey was conducted to assess knowledge, attitude, and sources of information towards burn first aid among people referred to a burn centre in the north of Iran in 2023. In this survey, a convenience sampling method was adopted. The variables consisted of four items on socio-demographic information, 15 items on knowledge, ten items on attitude, and one item on sources of information related to burn First aid. A total of 371 individuals responded to the survey. The mean age of participants was 31.90 ± 8.49 years old. The mean score of the total knowledge of the participants in the research was 6.04 ± 3.05. There was a statistically significant relationship between the variables of age, sex, marital status, place of residence, level of education, and history of receiving first aid training with the participants' knowledge level. The average score of the total attitude of the participants was 44.08 ± 3.88. Out of 371 participants, 214 people (57.7%) had an average attitude, and 157 people (42.3%) had a good attitude towards burn first aid. There was a statistically significant relationship between place of residence, level of education, and history of receiving first aid training with the participants' attitudes in the research. In addition, the level of knowledge had a statistically significant relationship with the participants' attitude level in the research (p-value <0.001). The majority of participants have limited knowledge of burn first aid. This lack of knowledge could lead to severe consequences. Therefore, healthcare organizations should review and promote consistent guidelines for burn first aid to tackle and minimize the effect of this grave injury.
