Abstract

Emergency craniotomy in patients with traumatic brain injury poses a significant risk for surgical site infections (SSIs). Understanding the risk factors and pathogenic characteristics of SSIs in this context is crucial for improving outcomes. This comprehensive retrospective analysis spanned from February 2020 to February 2023 at our institution. We included 25 patients with SSIs post-emergency craniotomy and a control group of 50 patients without SSIs. Data on various potential risk factors were collected, including demographic information, preoperative conditions, and intraoperative details. The BACT/ALERT3D Automated Bacterial Culture and Detection System was utilized for rapid bacterial pathogen identification. Statistical analyses included univariate and multivariate logistic regression to identify significant risk factors for SSIs. The study identified Klebsiella pneumoniae, Escherichia coli, and Staphylococcus aureus as the most prevalent pathogens in SSIs. Significant risk factors for SSIs included the lack of preoperative antibiotic use, postoperative drainage tube placement, diabetes mellitus, and the incorporation of invasive procedures, all of which showed a significant association with SSIs in the univariate analysis. The multivariate analysis further highlighted the protective effect of preoperative antibiotics and the increased risks associated with anaemia, diabetes mellitus, postoperative drainage tube placement, and the incorporation of invasive procedures. Our research underscores the critical role of factors like insufficient preoperative antibiotics, postoperative drainage, invasive techniques, anaemia, and diabetes mellitus in elevating the risk of surgical site infections in traumatic brain injury patients undergoing emergency craniotomy. Enhanced focus on these areas is essential for improving surgical outcomes.

Transcriptome and machine learning analysis of the impact of COVID-19 on mitochondria and multiorgan damage

Por: Yu-Yu Chang · An-Chi Wei — Enero 31st 2024 at 15:00

by Yu-Yu Chang, An-Chi Wei

The effects of coronavirus disease 2019 (COVID-19) primarily concern the respiratory tract and lungs; however, studies have shown that all organs are susceptible to infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 may involve multiorgan damage from direct viral invasion through angiotensin-converting enzyme 2 (ACE2), through inflammatory cytokine storms, or through other secondary pathways. This study involved the analysis of publicly accessible transcriptome data from the Gene Expression Omnibus (GEO) database for identifying significant differentially expressed genes related to COVID-19 and an investigation relating to the pathways associated with mitochondrial, cardiac, hepatic, and renal toxicity in COVID-19. Significant differentially expressed genes were identified and ranked by statistical approaches, and the genes derived by biological meaning were ranked by feature importance; both were utilized as machine learning features for verification. Sample set selection for machine learning was based on the performance, sample size, imbalanced data state, and overfitting assessment. Machine learning served as a verification tool by facilitating the testing of biological hypotheses by incorporating gene list adjustment. A subsequent in-depth study for gene and pathway network analysis was conducted to explore whether COVID-19 is associated with cardiac, hepatic, and renal impairments via mitochondrial infection. The analysis showed that potential cardiac, hepatic, and renal impairments in COVID-19 are associated with ACE2, inflammatory cytokine storms, and mitochondrial pathways, suggesting potential medical interventions for COVID-19-induced multiorgan damage.

Por: Yu‐Ling Chang · Ming‐Ju Hsieh · Ching‐I Pan · Shu‐Ting Shang · Yun‐Fang Tsai — Enero 19th 2024 at 10:00

Abstract

Aim and Objectives

To develop a Delirium Care Critical-Thinking Scale for nurses caring for patients in the intensive care unit and examine the scale's psychometric properties.

Background

There is a tool to evaluate nurses' critical thinking skills to determine nursing competency when delirium care is required.

Design

This cross-sectional, mixed-methods study.

Methods

The Delphi method was applied for collection and analysis of data during conceptualization and item generation of the tool (Phase I). Item analysis, assessment of validity and reliability of the scale (Phase II) involved 318 nurses recruited by convenience sampling from nine adult intensive care units in medicine and surgery at one medical centre. Confirmatory factor analysis assessed construct validity. Internal consistency and 2-week test–retest stability measured reliability. A Critical Thinking Disposition Inventory Scale examined concurrent validity.

Results

After three rounds, the Delphi method resulted in 31 scale items. Item analysis demonstrated construct reliability ranged from 9.23 to 16.18. Confirmatory factor analysis eliminated one item and extracted five factors: applying knowledge, confirming the problem and accuracy of information, reasoning logically, choosing appropriate strategies and remaining open-minded. Average variance extracted values of all factors indicated good convergent validity. Cronbach's α for internal consistency was .96 with good test-retest reliability. The correlation coefficient for concurrent validity was .301.

Conclusion

The new Delirium Care Critical-Thinking Scale for intensive care nurses was demonstrated to be a reliable and valid tool for evaluating their ability to assess patients with delirium.

Relevance to Clinical Practice

This new scale could be used to assess outcomes of education interventions and the effectiveness of nursing care quality involving patients with delirium in intensive and critical care units.

Reporting Method

The COSMIN checklist was used as the reporting guideline for this study.

Patient or Public Contribution

None.

Use of consecutive transcutaneous oxygen measurement when assessing the need for revascularization and association with the outcomes of ischemic diabetic ulcers

Abstract

This study compared the ankle-brachial index (ABI) with transcutaneous oxygen pressure (TcPO2) in assessing peripheral vascular disease (PVD) prevalence in 100 diabetic foot ulcer (DFU) patients. Patients were categorized into vascular or nonvascular reconstruction groups and underwent both ABI and TcPO2 measurements four times over 6 months. Predictive validity for PVD diagnosis was analysed using the area under the receiver-operating characteristic curve (AUC). The study found TcPO2 to be a superior predictor of PVD than ABI. Among the DFU patients, 51 with abnormal TcPO2 values underwent vascular reconstruction. Only TcPO2 values showed significant pretreatment differences between the groups and increased post-reconstruction. These values declined over a 6-month follow-up, whereas ABI values rose. For those with end-stage renal disease (ESRD), TcPO2 values saw a sharp decrease within 3 months. Pre-reconstruction TcPO2 was notably lower in amputation patients versus limb salvage surgery patients. In conclusion, TcPO2 is more effective than ABI for evaluating ischemic limb perfusion and revascularization necessity. It should be prioritized as the primary follow-up tool, especially for ESRD patients.

Diabetic foot wound ulcers management by vacuum sealing drainage: A meta‐analysis

Por: Liuqing Yang · Ning Zhao · Min Yang · Jiao Huang · Xiaomin Fu · Changjiang Lei · Pengzhu Cai — Enero 15th 2024 at 07:14

Abstract

The meta-analysis aimed to assess and compare diabetic foot wound ulcer management by vacuum sealing drainage. Using dichotomous or contentious random- or fixed-effects models, the outcomes of this meta-analysis were examined, and the odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were computed. Twenty-three examinations from 2000 to 2023 were enrolled for the present meta-analysis, including 1928 individuals with diabetic foot ulcers. Vacuum sealing drainage had significantly lower wound healing (OR, 2.35; 95% CI, 1.79–3.08, p < 0.001), lower duration of therapy (MD, −6.19; 95% CI, −10.06 to −2.32, p = 0.002), higher wound size reduction (MD, 4.22; 95% CI, 0.87–7.56, p = 0.01) and lower complication (OR, 0.32; 95% CI, 0.13–0.80, p = 0.01) compared with standard therapy in patients with diabetic foot ulcers. The examined data revealed that vacuum sealing drainage had significantly lower wound healing, duration of therapy and complication rates, as well as higher wound size reduction, compared with standard therapy in patients with diabetic foot ulcers. Yet, attention should be paid to its values since most of the selected examinations had a low sample size.

Therapeutic efficacy of platelet‐rich fibrin on surgical site wound healing in patients undergoing oral carcinoma resection: A meta‐analysis

Por: Tian Long · Changkai Li · Fan Xu · Junwen Xiao — Enero 12th 2024 at 06:44

Abstract

Oral carcinoma, a prevalent malignancy of the oral cavity, often results in surgical site wounds post-resection. The therapeutic efficacy of platelet-rich fibrin (PRF) in wound healing and scar formation has garnered significant attention. This meta-analysis aimed to evaluate the role of PRF in promoting surgical site wound healing and reducing scar formation following oral carcinoma resection. A systematic search, adhering to PRISMA guidelines, was conducted across multiple databases. The primary outcomes assessed were the Landry, Turnbull and Howley (LTH) wound healing index and the Manchester scar scale (MSS). Statistical evaluations were performed using RevMan 5.4 software. Six studies were incorporated, involving 93 patients treated with PRF and 97 in the control group. For the LTH index, significant improvements in wound healing were observed in the PRF group with I 2 = 74%, (Random: SMD: 3.70, 95% CIs: 2.66 to 4.75, p < 0.01). The Manchester scar scale assessment, which included 60 PRF-treated patients and 60 controls, indicated a significant reduction in scar formation in the PRF group I 2 = 79%, (Random: SMD: 9.13, 95% CIs: 6.06 to 12.20, p < 0.01). PRF demonstrates promising therapeutic potential in enhancing surgical site wound healing and reducing scar formation post oral carcinoma resection. The application of PRF has been associated with improved wound healing metrics and diminished scar severity. However, further high-quality studies are warranted to confirm these findings.

Sternal wound infections following internal mammary artery grafts for a coronary bypass: A meta‐analysis

Por: Mingmei Li · Zhenxing Yu · Qiong Chen · Qian Zhao · Xiang Chen · Changjiang Lei · Xiaohui Wang · Rui Yang — Enero 11th 2024 at 02:48

Abstract

The meta-analysis aims to evaluate and compare the sternal wound infections following internal mammary artery grafts for a coronary bypass. Examinations comparing bilateral internal mammary artery to single internal mammary artery for coronary artery bypass grafting were among the meta-analyses from various languages that met the inclusion criteria. Using dichotomous random- or fixed-effect models, the results of these investigations were examined, and the Odd Ratio (OR) with 95% confidence intervals (CIs) was computed. A total of 31 examinations from 2001 to 2023 were recruited for the current analysis including 181 503 personals with coronary artery bypass grafting. Bilateral internal mammary artery had significantly higher sternal wound infection (OR, 1.51; 95% CI, 1.37–1.68, p < 0.001), superficial sternal wound infection (OR, 1.72; 95% CI, 1.16–2.56, p = 0.007), deep sternal wound infection (OR, 1.62; 95% CI, 1.41–1.86, p < 0.001), sternal wound infection in diabetics (OR, 1.48; 95% CI, 1.16–1.90, p = 0.002), sternal wound infection in elderly (OR, 1.38; 95% CI, 1.22–1.57, p < 0.001), sternal wound infection in pedicled preparation (OR, 1.70; 95% CI, 1.30–2.23, p < 0.001) and sternal wound infection in skeletonized preparation (OR, 1.40; 95% CI, 1.09–1.81, p = 0.009) compared to single internal mammary artery in personals with coronary artery bypass grafting. Bilateral internal mammary artery grafting is linked to a higher risk of impaired wound healing, particularly in diabetic individuals, elderly, pedicled preparation, and skeletonized preparation. Nevertheless, caution should be exercised while interacting with its values since examinations were performed by different surgeons with different skills on different types of personals.

Are current wound classifications valid for predicting prognosis in people treated for limb‐threatening diabetic foot ulcers?

Abstract

This study aims to investigate whether the current wound classifications were valid for the treatment prognosis of subjects treated for limb-threatening diabetic foot ulcers (LTDFU). A total of 1548 patients with LTDFU and infection were studied, with wounds recorded using the Wagner, Texas, PEDIS and WIfI classifications while major lower extremity amputations (LEAs) or in-hospital mortality incidences were defined as poor outcomes. Among them, 153 (9.9%) patients received major LEAs and 38 (2.5%) patients died. After adjustments, the Wagner classification and Texas stage as well as clinical factors such as comorbidity with major adverse cardiac events (MACE), being under dialysis and having serum levels of C-reactive protein (CRP) and albumin were independent factors for prognosis. For patients without dialysis, Wagner and Texas stage stood out independently for prognosis. For patients on dialysis, only levels of CRP (odds ratio [OR] = 2.2 in Wagner, OR = 2.0 in WIfI, OR = 2.2 in Texas, OR = 2.3 in PEDIS) and albumin (OR = 0.4 in four classifications) were valid predictors. The Wagner system and Texas stage were valid for predicting prognosis in treatment for LTDFUs, suggesting a role of vascular perfusion. MACE history, levels of CRP and albumin level should assist in prediction; more significantly, only levels of CRP and albumin appeared valid for those subjects undergoing dialysis.

Meeting high-risk patient pain care needs through intensive primary care: a secondary analysis

Por: Giannitrapani · K. F. · Holliday · J. R. · McCaa · M. D. · Stockdale · S. · Bergman · A. A. · Katz · M. L. · Zulman · D. M. · Rubenstein · L. V. · Chang · E. T. — Enero 2nd 2024 at 16:31
Objective

Chronic pain disproportionately affects medically and psychosocially complex patients, many of whom are at high risk of hospitalisation. Pain prevalence among high-risk patients, however, is unknown, and pain is seldom a focus for improving high-risk patient outcomes. Our objective is to (1) evaluate pain frequency in a high-risk patient population and (2) identify intensive management (IM) programme features that patients and providers perceive as important for promoting patient-centred pain care within primary care (PC)-based IM.

Design

Secondary observational analysis of quantitative and qualitative evaluation data from a multisite randomised PC-based IM programme for high-risk patients.

Setting

Five integrated local Veterans Affairs (VA) healthcare systems within distinct VA administrative regions.

Participants

Staff and high-risk PC patients in the VA.

Intervention

A multisite randomised PC-based IM programme for high-risk patients.

Outcome measures

(a) Pain prevalence based on VA electronic administrative data and (b) transcripts of interviews with IM staff and patients that mentioned pain.

Results

Most (70%, 2593/3723) high-risk patients had at least moderate pain. Over one-third (38%, 40/104) of the interviewees mentioned pain or pain care. There were 89 pain-related comments addressing IM impacts on pain care within the 40 interview transcripts. Patient-identified themes were that IM improved communication and responsiveness to pain. PC provider-identified themes were that IM improved workload and access to expertise. IM team member-identified themes were that IM improved pain care coordination, facilitated non-opioid pain management options and mitigated provider compassion fatigue. No negative IM impacts on pain care were mentioned.

Conclusions

Pain is common among high-risk patients. Future IM evaluations should consider including a focus on pain and pain care, with attention to impacts on patients, PC providers and IM teams.

Risk factors contributing to postoperative surgical site infections in patients undergoing ankle fracture fixation: A systematic review and meta‐analysis

Por: Changxin Yin · Lu Sun — Diciembre 28th 2023 at 12:33

Abstract

Surgical site infections (SSIs) following ankle fracture fixation pose significant challenges in patient recovery and healthcare management. Identifying risk factors contributing to SSIs can aid in developing targeted prevention and treatment strategies. This systematic review and meta-analysis were conducted according to the PRISMA guidelines and the PICO framework. A comprehensive literature search across major databases, including PubMed, Embase, Web of Science and the Cochrane Library, was completed on September 26, 2023. The inclusion criteria encompassed peer-reviewed studies of various designs that investigated risk factors for SSIs post-ankle fracture fixation. Quality assessment was performed using the Newcastle-Ottawa Scale. Statistical analyses assessed heterogeneity and calculated combined effect sizes using fixed- or random-effects models, depending on the heterogeneity observed. The initial search yielded 1250 articles, with seven meeting the inclusion criteria after rigorous screening and full-text review. The included studies, conducted between 2006 and 2019, predominantly utilized case–control designs. The meta-analysis identified diabetes, open fractures, smoking, age, alcohol consumption, ASA score ≥3, high BMI, contaminated incisions, fracture dislocation and heart disease as significant risk factors for postoperative SSIs. Publication bias assessment showed no significant bias across studies. The identification of key risk factors such as diabetes, open fractures, smoking, advanced age, alcohol consumption, high ASA score, elevated BMI, contaminated incisions, fracture dislocation and heart disease is essential in managing SSIs post-ankle fracture fixation. Targeted interventions addressing these risk factors are crucial to reduce the incidence of SSIs and improve overall patient outcomes.

Influence of severity of illnesses on risk of death in intensive care unit patients with severity of pressure injuries as mediating variable

Por: Wen‐Pei Chang — Diciembre 27th 2023 at 11:53

Abstract

This study was to verify whether the severity of pressure injuries (PIs) in intensive care unit (ICU) patients plays a mediating role in the relationship between severity of their illnesses and risk of death. I examined adult patients admitted to the ICUs between 1 January 2014 and 31 August 2021. The average follow-up period was 11.34 months. A total of 390 ICU patients suffered from PIs. The influences of the APACHE II score of the ICU patients on the mediating variable ‘unstageable & DTPIs vs. Stage 1&2 PIs’ and on risk of death were significant. After controlling the influence of APACHE II score on risk of death, the influences of mediating variables ‘Stage 3&4 PIs vs. Stage 1&2 PIs’ and ‘unstageable & DTPIs vs. Stage 1&2 PIs’ on risk of death were also significant. The regression coefficient of APACHE II score of the ICU patients declined after the severity of PIs was included. The Sobel test on the indirect effects also reached the level of significance. The severity of illnesses is a factor that is beyond my control, severe PIs should still be prevented to lower the risk of death.

Carotenoids are antioxidants, which reduce various chronic diseases of human, and have many industrial applications. The halophilic Dunaliella parva (D. parva) is rich in carotenoids. The compounds CaCl2 and PEG are the popular metabolic enhancers. To further enhance carotenogenesis, D. parva was treated with two compounds polyethylene glycol (PEG) and CaCl2. Application of CaCl2 and PEG enhanced the carotenoids contents and the antioxidant activities of carotenoids compared to control group (no treatment of CaCl2 or PEG). The highest carotenoids contents were obtained by treating D. parva with 40 ppm CaCl2 (3.11 mg/g dry weight, DW) and 80 ppm PEG (2.78 mg/g DW) compared with control group (1.96 mg/g DW). When D. parva was treated with 40 ppm CaCl2 and 80 ppm PEG, protein contents reached the highest values (90.28 mg/g DW and 89.57 mg/g DW) compared to that of control group (73.42 mg/g DW). The antioxidant activities of carotenoids samples were determined. Generally, the antioxidant activities of carotenoids from D. parva treated with PEG and CaCl2 were superior to that of control group. The antioxidant activities of carotenoids mainly contained reducing power, hydroxyl radical scavenging activity and superoxide radical scavenging activity. The reducing powers of carotenoids extracts from 20 ppm CaCl2 group (2.07%/mg carotenoids) and 120 ppm PEG group (1.59%/mg carotenoids) were significantly higher than that of control group (2 group (70.33%/mg carotenoids) and 80 ppm PEG group (65.94%/mg carotenoids) were significantly higher than that of control group (D. parva.

A non-socially-sensitive predictive model of prostate cancer for Asian males with benign prostatic hyperplasia: A multi-site cross-sectional case-control study

Por: Heng-Jui Chang · Sin-Hua Moi · Yu-Jiun Chan · Tzuo-Yun Lan — Diciembre 11th 2023 at 15:00

by Heng-Jui Chang, Sin-Hua Moi, Yu-Jiun Chan, Tzuo-Yun Lan

Background

Benign prostatic hyperplasia (BPH) is common in aging Asian males and is associated with an excess risk of developing prostate cancer (PCa). However, discussions about socially-sensitive experiences such as sexual activity, which can significantly predict PCa risk, may be considered stigmatized in Asian culture. This study aimed to develop a predictive model for PCa risk in Asian males with BPH using non-socially-sensitive information.

Methods

A cross-sectional case-control study, with PCa patients as the cases and remaining as the controls, was conducted on a cohort of Taiwanese males with BPH from four medical institutions. Patients who met the inclusion criteria were enrolled, excluding those aged over 86 years or who had received human papillomavirus (HPV) vaccination. Non-socially-sensitive variables such as obesity, occupational exposure, HPV infection, and PCa family history score (FH score) were included in a fully adjusted logistic regression model, and depicted using a nomogram.

Results

Among 236 BPH patients, 45.3% had PCa. Obesity, occupational exposure, HPV infection, and family history of PCa were significantly associated with PCa risk. The FH score (OR = 1.89, 95% CI = 1.03–3.47, P = 0.041) had the highest impact, followed by HPV infection (OR = 1.47, 95% CI = 1.03–2.11, P = 0.034), occupational exposure (OR = 1.32, 95% CI = 1.15–1.51, P P = 0.005). The nomogram accurately depicted the predictive risk, and the model demonstrated robust performance compared to individual factors. In addition, the subgroup analysis results showed elderly age group could obtain more favorable predictive performance in our proposed model (AUC = 0.712).

Conclusion

This non-socially-sensitive predictive model for PCa risk in Taiwanese males with BPH integrates multiple factors that could provide acceptable PCa risk-predictive performance, especially for elderly BPH patients over 70 years, aiding clinical decision-making and early cancer detection.

Use of external control arms in immune-mediated inflammatory diseases: a systematic review

Por: Zayadi · A. · Edge · R. · Parker · C. E. · Macdonald · J. K. · Neustifter · B. · Chang · J. · Zhong · G. · Singh · S. · Feagan · B. G. · Ma · C. · Jairath · V. — Diciembre 9th 2023 at 17:51
Objectives

External control arms (ECAs) provide useful comparisons in clinical trials when randomised control arms are limited or not feasible. We conducted a systematic review to summarise applications of ECAs in trials of immune-mediated inflammatory diseases (IMIDs).

Design

Systematic review with an appraisal of ECA source quality rated across five domains (data collection, study populations, outcome definitions, reliability and comprehensiveness of the dataset, and other potential limitations) as high, low or unclear quality.

Data sources

Embase, Medline and Cochrane Central Register of Controlled Trial were searched through to 12 September 2023.

Eligibility criteria

Eligible studies were single-arm or randomised controlled trials (RCTs) of inflammatory bowel disease, pouchitis, rheumatoid arthritis, juvenile idiopathic arthritis, ankylosing spondylitis, psoriatic arthritis, psoriasis and atopic dermatitis in which an ECA was used as the comparator.

Data extraction and synthesis

Two authors independently screened the search results in duplicate. The characteristics of included studies, external data source(s), outcomes and statistical methods were recorded, and the quality of the ECA data source was assessed by two independent authors.

Results

Forty-three studies met the inclusion criteria (inflammatory bowel disease: 16, pouchitis: 1, rheumatoid arthritis: 12, juvenile idiopathic arthritis: 1, ankylosing spondylitis: 5, psoriasis: 3, multiple indications: 4). The majority of these trials were single-arm (33/43) and enrolled adult patients (34/43). All included studies used a historical control rather than a contemporaneous ECA. In RCTs, ECAs were most often derived from the placebo arm of another RCT (6/10). In single-arm trials, historical case series were the most common ECA source (19/33). Most studies (31/43) did not employ a statistical approach to generate the ECA from historical data.

Conclusions

Standardised ECA methodology and reporting conventions are lacking for IMIDs trials. The establishment of ECA reporting guidelines may enhance the rigour and transparency of future research.

Pain is strongly associated with neuro-immune activation. Thus, the emerging role of the endocannabinoid system in neuro-inflammation is important. Acupuncture has been used for over 2500 years and is widely accepted for the management of pain. Our study aimed to investigate the effects of electroacupuncture on the regulation of cannabinoid receptor type 1 within the peripheral nervous system. Inflammatory pain was induced by injecting Complete Freund’s adjuvant to induce mechanical and thermal hyperalgesia. Electroacupuncture significantly attenuated the mechanical and thermal sensitivities, and AM251, a cannabinoid receptor type 1 antagonist, eliminated these effects. Dual immunofluorescence staining demonstrated that electroacupuncture elevated expression of cannabinoid receptor type 1, co-localized with Nav 1.8. Furthermore, electroacupuncture significantly reduced levels of Nav 1.8 and COX-2 by western blot analysis, but not vice versa as AM251 treatment. Our data indicate that electroacupuncture mediates antinociceptive effects through peripheral endocannabinoid system signaling pathway and provide evidence that electroacupuncture is beneficial for pain treatment.

Morphological characteristics of facial scars: A retrospective analysis according to scar location, onset, age, and cause

Por: Gyeong Hoon Kim · Woo Jin Lee · Joon Min Jung · Chong Hyun Won · Sung Eun Chang · Mi Woo Lee · Ik Jun Moon — Diciembre 7th 2023 at 06:29

Abstract

The morphology of facial scars shows a wide variation in terms of texture and colour. To date, there are no reliable predictors of aberrant scarring. We conducted a retrospective analysis to identify factors associated with specific scar features and types. Photographs and medical records of 428 patients with facial scars were retrospectively reviewed. Patients with keloids were excluded. The mean age of the patients was 45.43 ± 23.13 years with a male-to-female ratio of 1:1.36. Atrophic scars were the most common (42.8%), followed by flat scars (38.7%) and hypertrophic scars (18.5%). Scars on the forehead were more likely to be atrophic, whereas scars on the chin/jaw and around the mouth were more likely to be hypertrophic. Hypopigmentation was significantly more common in scars located on the forehead. Redness (erythema) was significantly more common in scars located on the chin/jaw. Old scars were less likely to be erythematous, and hypertrophic. Atrophic scars were more common in younger patients. Scars caused by dermatologic conditions, such as acne, were more likely to be atrophic, whereas surgical scars had the lowest risk of being atrophic or hypertrophic. In conclusion, the location, onset, and cause of facial scars were associated with specific features of scars.

Development and validation of a Chinese version chronic wound health‐related quality of life instrument: A methodological study

Abstract

Aims and Objectives

To develop a Chinese version of a chronic wound health-related quality of life (QoL) instrument and to examine the psychometric properties of this instrument.

Background

Existing QoL instruments are not tailored to the linguistic and cultural characteristics of Chinese-speaking patients; a version addressing this gap will increase clinical understanding of their healthcare experience and may help guide chronic wound care.

Design

A methodological study.

Methods

The method advanced by DeVellis (2017) was used to develop the instrument. An initial pool of 38 items was created. To optimize scale length and test reliability and validity, exploratory and confirmatory factor analyses were conducted. A total of 23 items formed the final pool. After two rounds of expert discussions, the average content validity index of the final 23 items was .89.

Results

A total of 226 patients completed the instrument and were divided into two groups for further analysis. Exploratory factor analysis revealed that 15 items remained in four factors (social activity restrictions, physical and psychological disturbance, wound burden and daily life limitation), which accounted for 64.87% of the variance. Confirmatory factor analysis revealed an acceptable fit of the hypothesized factor structure and the convergent and discriminant validities were achieved. Cronbach's α coefficients for each factor were .807, .773, .799 and .713, respectively.

Conclusion

The Chinese version of a chronic wound health-related QoL instrument consists of 15 items in four subscales and demonstrates good reliability and validity.

Relevance to Clinical Practice

This instrument can be used intermittently or continuously to evaluate the treatment effect of chronic wounds by assessing health-related QoL. Scholars in Chinese-speaking regions may find this culturally compatible instrument useful when conducting studies related to chronic wounds.

Patient or Public Contribution

Two hundred twenty-six participants provided their perspectives on health-related QoL.

Background

This study examined the long-term risks of heart failure (HF) and coronary heart disease (CHD) following traumatic brain injury (TBI), focusing on gender differences.

Methods

Data from Taiwan’s National Health Insurance Research Database included 29,570 TBI patients and 118,280 matched controls based on propensity scores.

Results

The TBI cohort had higher incidences of CHD and HF (9.76 vs. 9.07 per 1000 person-years; 4.40 vs. 3.88 per 1000 person-years). Adjusted analyses showed a significantly higher risk of HF in the TBI group (adjusted hazard ratio = 1.08, 95% CI = 1.01–1.17, P = 0.031). The increased CHD risk in the TBI cohort became insignificant after adjustment. Subgroup analysis by gender revealed higher HF risk in men (aHR = 1.14, 95% CI = 1.03–1.25, P = 0.010) and higher CHD risk in women under 50 (aHR = 1.32, 95% CI = 1.15–1.52, P Conclusion

Our results suggest that TBI increases the risk of HF and CHD in this nationwide cohort of Taiwanese citizens. Gender influences the risks differently, with men at higher HF risk and younger women at higher CHD risk. Beta-blockers have a neutral effect on HF and CHD risk.
