Near‐infrared spectroscopy data for foot skin oxygen saturation in healthy subjects

Abstract

Our objective was to evaluate normative data for near-infrared spectroscopy (NIRS) in 110 healthy volunteers by Fitzpatrick skin type (FST) and region of the foot. We obtained measurements of the dorsum and plantar foot using a commercially available device (SnapshotNIR, Kent Imaging, Calgary Canada). On the dorsum of the foot, people with FST6 had significantly lower oxygen saturation compared to FST1-5 (p < 0.001), lower oxyhaemoglobin compared to FST2-5 (p = 0.001), but there was no difference in deoxyhaemoglobin. No differences were found on the plantar foot. When comparing dorsal and plantar foot, there was higher oxyhaemoglobin (0.40 ± 0.09 vs. 0.51 ± 0.12, p < 0.001) and deoxyhaemoglobin (0.16 ± 0.05 vs. 0.21 ± 0.05, p < 0.001) on the plantar foot, but no differences in oxygen saturation (dorsal 70.7 ± 10.8, plantar 70.0 ± 9.5, p = 0.414). In 6.4% of feet, there were black areas, for which no NIRS measurements could be generated. All areas with no data were on the dorsal foot and only found in FST 5–6. People with FST6 had significantly larger areas with no data compared to FST 5 (22.2 cm2 ± 20.4 vs. 1.9 cm2 ± 0.90, p = 0.007). These findings should be considered when using NIRS technology. Skin pigmentation should be evaluated in future NIRS studies.

Predictive value of serum albumin and calcium levels in burn patients with Pseudomonas aeruginosa infection: A comprehensive analysis of clinical outcomes

Abstract

In the ongoing challenge to reduce burn-associated mortality rates, this study explores the predictive capacity of clinical factors in burn patients, focusing on vitamin D, calcium, and serum albumin levels during hospitalisation in cases with Pseudomonas aeruginosa infection. Our research involves a comprehensive analysis of 100 burn patients, encompassing crucial clinical parameters such as the burn severity index, serum albumin, vitamin D, and calcium levels at admission. Data were meticulously entered into IBM Statistics SPSS software version 28 and subjected to statistical analysis. The study reveals an average patient age of 39.75 years and a notable 34% mortality rate. Additionally, the average lengths of hospital and intensive care unit (ICU) stays are determined to be 11.33 and 7.79 days, respectively. Significantly, a correlation between calcium and albumin variables and treatment outcomes is established, showcasing their potential to predict variable changes in patient mortality rates. Furthermore, a noteworthy association is observed between serum calcium levels and the duration of ICU hospitalisation. In conclusion, albumin and calcium variables emerge as sensitive and specific indicators for predicting outcomes in burn patients. Importantly, the independence of these factors from the physician's experience and diagnosis reduces human error and thus increases the accuracy of mortality prediction in this patient population.

Risk and protective factors associated with wound infection after neurosurgical procedures: A meta‐analysis

Abstract

To systematically evaluate the risk factors for wound infection at the surgical site after neurosurgical craniotomy by meta-analysis, and to provide an evidence-based basis for preventing the occurrence of wound infection. A computerised search of PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure and Wanfang database was conducted for relevant studies on risk factors for surgical site wound infection after neurosurgical craniotomy published from the database inception to November 2023. Two researchers independently screened the literature, extracted the data and performed quality assessment in strict accordance with the inclusion and exclusion criteria. STATA 17.0 software was applied for data analysis. Overall, 18 papers with 17 608 craniotomy patients were included, of which 905 patients developed wound infections. The analysis showed that underlying diseases [OR = 2.50, 95% CI (1.68, 3.72), p < 0.001] and emergency surgery [OR = 2.47, 95% CI (1.80, 3.38), p < 0.001] were the risk factors for developing wound infections after craniotomy, age < 60 years [OR = 0.72, 95% CI (0.52, 0.98), p = 0.039] was a protective factor for wound infections; whereas sex [OR = 1.11, 95% CI (0.98, 1.27), p = 0.112] and the antimicrobial use [OR = 1.30, 95% CI (0.81 2.09), p = 0.276] were not associated with the presence or absence of wound infection after craniotomy. Underlying disease and emergency surgery are risk factors for developing wound infections after craniotomy, whereas age < 60 years is a protective factor. Clinicians can reduce the occurrence of postoperative wound infections by communicating with patients in advance about the possibility of postoperative wound infections based on these factors, and by doing a good job of preventing postoperative wound infections.

The impact of different antibiotic injection regimens on patients with severe infections: A meta‐analysis

Abstract

Severe infection is a critical health threat to humans, and antibiotic treatment is one of the main therapeutic approaches. Nevertheless, the efficacy of various antibiotic injection regimens in severe infection patients remains uncertain. This study aimed to comprehensively evaluate the impact of various antibiotic injection strategies on patients with severe infection through a meta-analysis. Relevant research literature was collected by searching databases such as PubMed, Embase, and Cochrane Library. The retrieved literature was screened according to inclusion and exclusion criteria. Relevant data, including study design, sample size, and antibiotic regimens, were extracted from the included studies. The Cochrane Collaboration's Risk of Bias tool was employed to assess the risk of bias in each study. Statistical analysis was performed based on the results of the included studies. A total of 15 articles were included, covering various types of severe infection patients, including pulmonary and abdominal infections. The analysis provided insights into mortality rates, treatment efficacy, adverse reactions (ARs), Acute Physiology and Chronic Health Evaluation (APACHE) scores, among other outcomes. The results indicated that combination therapy was superior to monotherapy in terms of mortality rate, treatment efficacy, and APACHE scores, while the incidence of ARs was lower in the monotherapy group compared to the combination therapy group (p < 0.05). Combination therapy showed better treatment efficacy compared to monotherapy, although it was associated with a higher incidence of ARs.

Investigation of morbidity, length of stay, and healthcare costs of inpatient paediatric burns

Abstract

Burn injuries are the third most common cause of death in children due to trauma. Hospitalizations related to burn injuries are common. Prolonged hospitalization associated with burn treatment can result in increased resource utilization, leading to higher costs. Thus, it is essential to investigate these areas to reduce costs. The study investigated the morbidity and length of hospital stay of paediatric burn patients, as well as calculated the social security costs of hospitalization and treatment. The retrospective observational descriptive study examined the medical records of 774 paediatric patients treated in a burn intensive care unit at a tertiary medical faculty hospital between 01 March 2019 and 31 March 2022. The invoice records of payments made by the Social Security Institution to the hospital in return for health services provided to patients were examined. The healthcare costs were calculated. A total of 57.6% of the participants were boys and 79.2% were between the ages of 1–4. About 90% of the cases involved burns with a total body surface area (TBSA) of less than 20% and a 2nd-degree burn depth. Scalding was the most common cause of burns (88.2%). Among all patients, the mortality rate was 2.1% (n = 16). The mean length of hospital stay was 10.29 ± 9.59 days. The mean cost per day was 212.02 ± 190.94 US dollars ($US), and the cost per 1% TBSA was 241.70 ± 301.32 $US. According to the causes of burn injury, the mean cost of electricity was 5000.77 ± 8101.85 $US, fire 4818.02 ± 5852.22 $US, and chemical 3285.49 ± 4503.2 $US were observed in the first 3 ranks respectively. According to this study, paediatric burn cases occur due to preventable causes, and even though the mortality rate was low, the severity of burns, TBSA%, and presence of complications caused prolonged lengths of hospital stays, which caused social security costs to rise.

Topical metformin accelerates wound healing by promoting collagen synthesis and inhibiting apoptosis in a diabetic wound model

Abstract

The wound healing process, which is a pathophysiological process that includes various phases, is interrupted in diabetes due to hyperglycemia, and since deterioration occurs in these phases, a normal healing process is not observed. The aim of the current study is to investigate the proliferative and antiapoptotic effects of metformin on wound healing after topical application on diabetic and non-diabetic wounds. For this purpose, we applied metformin topically on the full-thickness excisional wound model we created in diabetic and nondiabetic groups. We investigated the effects of metformin on the apoptotic index by the Terminal deoxynucleotidyl transferase mediated dUTP Nick-End Labeling method and on collagen-I, collagen-III, p53, and c-jun expression levels by quantitative reverse transcription polymerase chain reaction technique in wound biopsy tissues. Our results showed that c-jun and p53 mRNA levels and apoptotic index increased with the effect of diabetes, while collagen synthesis was disrupted. As a result of the study, we showed that metformin increases cellular proliferation and has anti-apoptotic effects by increasing collagen-I/III expression and decreasing p53/c-jun level, especially in diabetic wounds and also in normal wounds. In conclusion, the topical effect of metformin on diabetic wounds reversed the adverse effects caused by diabetes, increasing the wound healing rate and improving the wound repair process.

The effect of bed exercises following major abdominal surgery on early ambulation, mobilization, pain and anxiety: A randomized‐controlled trial

Abstract

This randomized-controlled trial aimed to investigate the effect of bed exercises on postoperative anxiety, pain, early ambulation and mobilization. This study was conducted with a randomized-controlled trial design and in the general surgical clinic of a research and training hospital. A total of 120 patients (60 in the experimental group and 60 in the control group) scheduled for major abdominal surgery took part in the study. The data were collected using a patient information form, the Anxiety Specific to Surgery Questionnaire and the Visual Analog Scale through face-to-face interviews. The patients in the experimental group performed 15-min bed exercises on the day of their operation, as well as on the postoperative first and second days, and the control group underwent only the routinely performed procedures in the clinic. The data were analysed using descriptive statistics, analysis of variance and t-tests. The sample of our study included major abdominal surgery patients. Ambulation was achieved at a mean time of 4 h earlier in the experimental group. On the postoperative first and second days, the patients in the experimental group had mean mobilization durations that were approximately 2 h longer compared with the patients in the control group. Moreover, the postoperative pain and anxiety levels of the patients in the experimental group were significantly lower than those of the patients in the control group (p < 0.05). We recommend that bed exercises be performed to lower anxiety and pain severity, achieve early ambulation and increase the duration of mobilization among patients following major abdominal surgery.

The incidence of intraoperatively acquired pressure injuries in the park‐bench position was reduced by applying soft silicone multilayer foam dressings

Abstract

The Park-Bench Position (PBP) is associated with a high incidence rate of intraoperatively acquired pressure injuries (IAPIs). Preventive measures must be established to prevent the development of IAPIs. We investigated the risk factors for PBP by applying a soft silicone multilayered foam dressing (SMD) under core temperature management to prevent IAPIs. We conducted a prospective, single-centre, open-label observational study of patients undergoing elective neurosurgery operations using PBP in a university hospital in Japan. The incidence rate of IAPIs in this study was compared with that in our two previous studies, in which a film dressing was applied and core temperature management was not performed. IAPIs developed in 90 patients (6.7%); in the lateral thoracic region in five patients and the iliac crest region in one patient. The operative time (every 1 h: p = 0.0001, OR: odds ratio 3.62, 95% CI: confidence interval 1.73–11.42) was significantly associated with the incidence of IAPIs. In our two previous studies, the incidence rate of IAPIs was 11.0% and 24.1%, respectively, when film dressing was used. SMD may weaken the involvement of risk factors in IAPIs.
