ABSTRACT

OBJECTIVES: To describe the current state of research and future research hotspots through a metrological analysis of the literature in the field of forensic anthropological remains identification research.

METHODS: The data retrieved and extracted from the Web of Science Core Collection (WoSCC), the core database of the Web of Science information service platform (hereinafter referred to as “WoS”), was used to analyze the trends and topic changes in research on forensic identification of human remains from 1991 to 2022. Network visualisation of publication trends, countries (regions), institutions, authors and topics related to the identification of remains in forensic anthropology was analysed using python 3.9.2 and Gephi 0.10.

RESULTS: A total of 873 papers written in English in the field of forensic anthropological remains identification research were obtained. The journal with the largest number of publications was Forensic Science International (164 articles). The country (region) with the largest number of published papers was China (90 articles). Katholieke Univ Leuven (Netherlands, 21 articles) was the institution with the largest number of publications. Topic analysis revealed that the focus of forensic anthropological remains identification research was sex estimation and age estimation, and the most commonly studied remains were teeth.

CONCLUSIONS: The volume of publications in the field of forensic anthropological remains identification research has a distinct phasing. However, the scope of both international and domestic collaborations remains limited. Traditionally, human remains identification has primarily relied on key areas such as the pelvis, skull, and teeth. Looking ahead, future research will likely focus on the more accurate and efficient identification of multiple skeletal remains through the use of machine learning and deep learning techniques.

ABSTRACT

OBJECTIVES: To explore the effects of different test positions on quantitative muscle strength of wrist and finger flexor muscle groups and to establish a standardized muscle strength test protocol for each muscle group.

METHODS: Forty healthy subjects (12 males and 28 females) were recruited. A portable digital quantitative muscle strength tester, Micro FET2^TM, was used to measure the flexor muscle strength of each finger and the wrist joint at the 30° extension, 0° neutral, and 30° flexion, respectively. Palmar abduction strength of the thumb was measured at 30° and 60°, respectively. Ten subjects were randomly selected from the 40 subjects, and the quantitative muscle strength of each muscle group was tested again by the same operator after an interval of 10 to 15 days.

RESULTS: Except for the fact that in males, there was no significant difference in flexor muscle strength of thumb and wrist joint between 30° of wrist extension and neutral 0° position, the muscle strength of the other fingers flexion and wrist palmar flexor showed the following characteristics：30° of wrist extension > neutral 0° position > 30° of flexion, and the PAST was 30°>60°; The flexor muscle strength of all the subjects was thumb > index finger > middle finger > ring finger > little finger; All muscle strength values of male were greater than those of female, and the difference was statistically significant (P<0.05); There was no significant difference between the left and right side muscle strength values of all subjects (P>0.05). The reliability of muscle strength values measured at different times in 10 subjects was good.

CONCLUSIONS: The quantitative muscle strength of each muscle group of the hand and wrist is affected by the test position, and a standardized and uniformed test position should be adopted in the actual identification. Micro FET2^TM has good reliability for hand and wrist quantitative muscle strength testing. The 30° extension of the wrist can be used as the best standardized test position for the flexion muscle strength of each finger and wrist joint. The 30° position can be used as the best standardized test position for PAST.

ABSTRACT

AIM: To determine the occurrence of occupational stress among Palestinian nurses, and their associated sources and risk factors.

DESIGN: A cross-sectional descriptive design.

METHODS: A total of 250 registered nurses from eight governmental hospitals, using a convenience sampling method. Data collection were conducted using the 30-items self-reported Occupational Stress Scale from December 2022 to March 2023. Descriptive statistics, independent sample t-test, one-way ANOVA, and multiple linear regression analysis were applied to analysis data. Data analysis included descriptive statistics, independent sample t-test, one-way ANOVA, and multiple linear regression analysis.

RESULTS: The prevalence of high occupational stress levels was 64.8% (Mean = 3.9 out of 5). The main sources of stress are too much responsibility and work, understaffing, lack of promotion and recognition, inadequate pay, time pressure, and management style. The results regression analysis demonstrated that male nurses with a Masters or PhD degree and those working in fixed shifts experienced higher occupational stress. Moreover, participants who worked overtime hours were more susceptible to stress.

CONCLUSIONS: The research indicates that occupational stress presents a notable challenge for nurses in the Gaza Strip, Palestine. It suggests that in order to alleviate this stress, decision-makers in healthcare policy and hospital management should prioritize the execution of strategies aimed at addressing the primary stressors and risk factors identified.

REPORTING METHOD: This study adhered to the STROBE guidelines.

PUBLIC CONTRIBUTION: A total of 250 registered nurses were taken part in this study by answering a self-administered study survey.

ABSTRACT

The Quality of Life Profile for spinal deformities (QLPSD) was developed to evaluate the quality of life of patients with scoliosis and other spinal deformities. The purpose of the study was to systematically translate the QLPSD into Turkish and examine the reliability and validity of the Turkish version. This methodological study was conducted with 125 participants with idiopathic scoliosis. After the translation of the QLPSD into Turkish systematically, all participants answered the Turkish version of the QLPSD (T-QLPSD) and Scoliosis Research Society-22 items (SRS-22) questionnaires. Intraclass correlation coefficient (ICC) and Cronbach’s α statistics were used to test the reliability of the tools: convergent and construct validity of the tools was assessed using exploratory factor analysis and Pearson’s correlation analysis. One hundred twenty-five participants were included in the study. The mean age of them was 13.7 ± 2.2 years. For the T-QLPSD total score, Cronbach’s α was 0.91, and the ICC was 0.94. A very good correlation was found between T-QLPSD and SRS-22 total scores (r = -0.71). Participants with mild scoliosis reported less back pain (P = .038), better back flexibility (P=.001), and body image (P=.044) compared to moderate scoliosis. The T-QLPSD was found to be a reliable and valid scale for assessing quality of life in idiopathic scoliotic patients in Türkiye.

ABSTRACT

Carbapenem-resistant Klebsiella pneumoniae (CRKP) infection has become a significant threat to global health. The application of chemical disinfectants is an effective infection control strategy to prevent the spread of CRKP in hospital environments. However, bacteria have shown reduced sensitivity to clinical disinfectants in recent years. Furthermore, bacteria can acquire antibiotic resistance due to the induction of disinfectants, posing a considerable challenge to hospital infection prevention and control. This study collected 68 CRKP strains from the Fifth Affiliated Hospital of Xinjiang Medical University in China from 2023 to 2024. These strains were isolated from the sputum, urine, and whole blood samples of patients diagnosed with CRKP infection. Antibiotic susceptibility tests were performed on CRKP strains. Concurrently, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of disinfectants (benzalkonium bromide, 1% iodophor disinfectant, alcohol, and chlorine-containing disinfectant) against the test isolates were determined by the broth microdilution method. The efflux pump genes (cepA, qacE, qacEΔ1, qacEΔ1-SUL1, oqxA, and oqxB) were detected using polymerase chain reaction. The results showed that 21 out of the 68 CRKP strains exhibited extensive drug resistance, whereas 47 were nonextensively drug-resistant. The MIC value for benzalkonium bromide disinfectants displayed statistically significant differences (p < 0.05) between extensively drug-resistant (XDR) and non-XDR strains. Additionally, the MBC values for benzalkonium bromide disinfectants and 1% iodophor disinfectants displayed statistically significant differences (p < 0.05) between XDR and non-XDR strains. The detection rates for the efflux pump genes were as follows: cepA 52.9%, qacE 39.7%, qacEΔ1 35.2%, qacEΔ1-SUL1 52.9%, oqxA 30.8%, and oqxB 32.3%. The detection rate of the qacEΔ1-SUL1 gene in XDR CRKP strains was significantly higher than in non-XDR CRKP strains (p < 0.05). This indicates a potential link between CRKP bacterial disinfectant efflux pump genes and CRKP bacterial resistance patterns. Ongoing monitoring of the declining sensitivity of XDR strains against disinfectants is essential for the effective control and prevention of superbug.

ABSTRACT

PURPOSE: Systematic review and meta-analysis to examine common static postural parameters between participants with and without low back pain (LBP).

METHODS: Systematic search on the PubMed, CINAHL, Embase and SCOPUS databases using keywords ‘posture’ and ‘low back pain’. Observational studies comparing static postural outcomes (e.g. lumbar lordosis) between participants with and without LBP were included. Two independent reviewers conducted screening, data extraction and quality assessment. Methodological quality was assessed using Joanna Briggs Institute’s critical appraisal tools.

RESULTS: Studies included in review = 46 (5,097 LBP; 6,974 controls); meta-analysis = 36 (3,617 LBP; 4,323 controls). Quality of included studies was mixed. Pelvic tilt was statistically significantly higher in participants with LBP compared to controls (n = 23; 2,540 LBP; 3,090 controls; SMD:0.23, 95%CI:0.10,0.35, p < 0.01, I²=72%). Lumbar lordosis and sacral slope may be lower in participants with LBP; pelvic incidence may be higher in this group; both were not statistically significant and the between study heterogeneity was high. Thoracic kyphosis and leg length discrepancy showed no difference between groups.

CONCLUSIONS: Lumbopelvic mechanisms may be altered in people with LBP, but no firm conclusions could be made. Pelvic tilt appeared to be increased in participants with LBP. Postural variable measurement needs standardisation. Better reporting of study characteristics is warranted.Implications for rehabilitationLumbo pelvic parameters especially pelvic tilt may be altered in people with low back pain, although no firm conclusion could be made due to the high heterogeneity between studies.Postural assessment within low back pain rehabilitation may therefore require an individualistic approach.

ABSTRACT

BACKGROUND AND OBJECTIVE: COVID-19 pandemic gave rise to an increase in demand for pneumococcal and influenza vaccines. Several approaches to improve vaccination rates among different populations were investigated to address this need. Social media may be used as a platform to promote and improve vaccination rates. The study aimed to determine the effect of social media promotion, on the number of patients requesting vaccination in a government tertiary hospital.

METHODS: The study was conducted using a quasi-experimental design. A telehealth-based vaccination delivery system was established. The need for vaccination against flu and pneumonia was then promoted on a social media platform during the first month of the study. Posters on the risk of not being vaccinated and safety profile of vaccines were added on the second month. The number of requests for vaccination for each month was compared. Social media metrics of the two months of the study were likewise described.

RESULTS: A total of 23 requests for vaccination were recorded, 11 on the first month and 12 on the second month. When a boost in advertising for the posts was implemented, twice as many requests were made during the third week of the second month as compared to the previous month (5 vs 10). Social media promotion with poster showed higher average in reach, engagement and comments per week than without poster. The mean differences among the social media metrics, however, were not statistically significant.

CONCLUSION: Promotion with posters resulted in a slight increase in number of vaccination requests. Further increase in requests may require a more refined social media promotional strategy.

ABSTRACT

PURPOSE: The indications for distal scaphoid excision are limited to localized wrist arthritis surrounding the scaphoid, as a result of scaphoid nonunion advanced collapse or scapho-trapezio-trapezoid joint arthritis. The procedure historically has led to relief of symptoms and improvement in strength. Our aim was to examine the outcomes of this procedure in patients with scaphoid fracture nonunion.

METHODS: This is a single-center retrospective case series of 12 consecutive patients who underwent distal scaphoid excision after scaphoid fracture nonunion. Patients were divided into the following two groups based on nonunion chronicity: chronic (more than a year) and nonchronic (less than a year). Clinical and radiographic data were examined using descriptive statistics.

RESULTS: Our cohort consisted of 12 patients, 10 men (83%) and 2 women (17%), with a mean age of 37.6 ± 13.6 years. Eight patients had a chronic scaphoid fracture nonunion (six had a neglected scaphoid fracture and two had a nonunion after scaphoid open reduction and internal fixation with bone graft), and four patients had a nonchronic fracture nonunion (two had failed cast treatment and two had nonunion after scaphoid open reduction and internal fixation with bone graft). Before surgery, all patients complained of pain and four had numbness (all in the chronic group). After an average of 21 weeks after surgery, seven patients (58%) reported continued pain, two patients reported ulnar side pain, and one underwent arthroscopic synovectomy. All patients who started with a normal radiolunate angle continued to have a normal angle, whereas patients who had dorsal intercalated segmental instability prior to surgery persisted with it after surgery, except for a patient who underwent midcarpal fusion and had their radiolunate angle corrected.

CONCLUSIONS: Distal scaphoid excision is an effective procedure for carefully selected patients with periscaphoid wrist arthrosis. Patients with recent scaphoid fractures that failed treatment may also be treated with distal scaphoid resection.

ABSTRACT

PURPOSE: Distal radius fractures (DRF) are among the most commonly encountered fractures. The population of the United States is rapidly growing, aging, and diversifying. This study was undertaken to better understand current incidences and treatment trends across all ages, gender, and races to inform resource allocation and to potentially address treatment inequities.

METHODS: The TriNetX US Collaborative Network was queried for all patients diagnosed with DRFs from 2017 to 2022. Cohorts were defined by inclusion and exclusion of Current Procedural Terminology procedure codes and categorized into operative and nonsurgical groups. Statistical analysis was performed to determine differences in management among demographic groups across the 6-year time period.

RESULTS: Incidence rates of operative intervention for DRF increased from 19.6% in 2017 to 23.6% in 2022. Incidence rates of operative intervention increased from 21.7% to 25.2% for females and from 15.3% to 19.7% for males. A bimodal distribution was observed in females with more fractures occurring in the pediatric and geriatric ages, but this distribution was not observed in males. All demographic groups had an overall higher incidence of nonsurgical intervention. Patients aged 40-64 years were more likely to undergo operative intervention than patients 18-39 years. Females were more likely to undergo operative intervention than males. White patients were more likely to undergo operative intervention than Black patients and Asian patients.

CONCLUSIONS: The incidence of DRFs continues to climb, as does their rate of operative management. The classic bimodal distribution was observed in females, but not males. However, differences in management of DRFs were also observed across different demographic groups with ongoing racial disparities. Future consideration should be taken into optimizing treatment disparities relative to demographic status.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the efficacy of a web tutorial on perceptions of pain management and usage of opioids after carpal tunnel release surgery (post-CTR).

METHODS: A web tutorial was developed by the authors, and patients were consented and enrolled if they were over the age of 18 years, could speak and understand English, and were having CTR. Patients were randomized to either view or not view the web tutorial before surgery, and all patients took a 19-question online survey approximately 2 weeks after surgery to assess their views on pain management and their self-reported opioid usage. All patients received standard-of-care instructions for postoperative pain management and were prescribed fifteen 5 mg tablets of oxycodone. Independent sample t tests, Wilcoxon rank sum tests, and chi-square tests were used to evaluate variables of interest.

RESULTS: Sixty-seven patients were enrolled, with 17 lost to follow-up; therefore, 50 patients were included in the final study cohort and completed the online survey (n = 25/group). There were no statistically significant differences in age, gender (patient reported gender), race, and opioid use history between the groups, but there was a difference in education level with the group that did not watch the video having proportionally more participants whose highest level of education was postgraduate (36% vs 8%) and high school (24% vs 16%). There were no differences between groups in the perceptions of pain post-CTR based on survey statements, in reported opioid consumption on post-op day 1, or in perceived risk of prolonged opioid use. Conversely, on post-op days 2-6 (8% vs 28%) and 7-14 (0% vs 20%), fewer participants from the group that watched the video reported any opioid usage compared with the group that did not watch the video.

CONCLUSIONS: Our web tutorial did not notably impact the way patients perceived pain management or opioid risks post-CTR. However, a smaller proportion of the group that watched our tutorial reported opioid consumption post-CTR relative to the group that did not view our tutorial, suggesting that web tutorials may be a viable way to encourage patients to confer to minimal opioid usage and pain management regimens.
