Management and outcomes of cerebrovascular injuries after gunshot wounds to the cervical spine

Study designThis study was a multicenter retrospective analysis of cervical spine gunshot wound (GSW) patients. ObjectiveThe present study was conducted to evaluate the management and outcomes of vascular injuries following GSW involving the cervical spine. Summary of background dataGunshot wounds (GSW) injuring the cervical spine are associated with high rates of vascular injury. MethodsCharts of patients with GSW involving the cervical spine at two Level 1 trauma centers were reviewed from 2010 to 2021 for demographics, injury characteristics, management and follow-up. Statistical analysis included T tests and ANOVA for comparisons of continuous variables and chi-square testing for categorical variables, non-parametric tests were used when indicated. Beta-binomial models were used to estimate the probabilities outcomes. Bayesian regression models were utilized to compute risk ratios (RR) and their 95 % confidence intervals (CI) to enhance the inferential robustness. Results40 patients with cervical spine GSW and associated cerebrovascular injury were included in our analysis. 15 % of patients had Biffl grade (BG) V injuries, 50 % grade IV, and 35 % grade III–I. Angiography was performed in 35 % of patients. 5 of these patients (BG V–III) required endovascular treatment for pseudoaneurysm obliteration or parent vessel sacrifice. 7 patients (22 %) showed evidence of progression. 70 % of patients were placed on antiplatelet therapy for stroke prevention. Bayesian regression models with a skeptical prior for cerebral ischemia revealed a mean RR of 4.82 (95 % CI 1.02–14.48) in the BG V group, 0.75 (95 % CI 0.13–2.26) in the BG IV group, and 0.61 (95 % CI 0.06–2.01) in the combined BG III-I group. For demise the mean RR was 3.41 (95 % CI 0.58–10.65) in the BG V group and 1.69 (95 % CI 0.29–5.97) in the BG IV group. In the high BG (V, IV) group, 54.55 % of patients treated with antiplatelet therapy had complications. None of the patients that were treated with antiplatelet therapy in the low BG (III–I) group had complications. ConclusionsCervical spine GSWs are associated with high-grade vascular injuries and may require early endovascular intervention. Additionally, a high rate of injury progression was seen on follow up imaging, requiring subsequent intervention. Reintervention and demise were common and observed in high BG (V, IV) groups. The incidence of stroke was low, especially in low BG (I–III) groups, suggesting that daily aspirin prophylaxis is adequate for long-term stroke prevention.

DNA methylation signatures provide novel diagnostic biomarkers and predict responses of immune therapy for breast cancer.

Breast cancer (BRCA) is one of the most common malignant tumors affecting women worldwide. DNA methylation modifications can influence oncogenic pathways and provide potential diagnostic and therapeutic targets for precision oncology. In this study, we used non-parametric permutation tests to identify differentially methylated positions (DMPs) between paired tumor and normal BRCA tissue samples from the Cancer Genome Atlas (TCGA) database. Then, we applied non-negative matrix factorization (NMF) to the DMPs to derive eight distinct DNA methylation signatures. Among them, signatures Hyper-S3 and Hypo-S4 signatures were associated with later tumor stages, while Hyper-S1 and Hypo-S3 exhibited higher methylation levels in earlier stages. Signature Hyper-S3 displayed an effect on overall survival. We further validated the four stage-associated signatures using an independent BRCA DNA methylation dataset from peripheral blood samples. Results demonstrated that 24 commonly hypomethylated sites in Hypo-S4 showed lower methylation in BRCA patients compared to healthy individuals, suggesting its potential as an early diagnostic biomarker. Furthermore, we found that methylation of 23 probes from four stage-related signatures exhibited predictive power for immune therapy response. Notably, methylation levels of all three probes from the Hypo-S4 and activity of the Hypo-S4 demonstrated highly positive relevance to PD-L1 gene expression, implying their significant predictive values for immunotherapy outcomes. GO and KEGG pathway enrichment analysis revealed that genes with these 23 immunotherapy-related methylation probes are mainly involved in glycan degradation or protein deglycosylation. These methylation signatures and probes may serve as novel epigenetic biomarkers for predicting tumor immunotherapy response. Our findings provide new insights into precision oncology approaches for BRCA.

The quality of life in orthognathic surgery: surgery first versus traditional orthognathic surgery evaluation.

This study aims to evaluate the differences in terms of Quality of life and the degree of satisfaction with the result obtained between the two groups of patients treated with the orthodontic first approach and surgery first approach, through administered questionnaires inserted in the post-operative phase. A total of 40 patients who previously underwent orthognathic surgery were included in this study, 20 treated with the orthodontic first approach and 20 treated with the Surgery First Approach. The impact of orthognathic surgery on patients' quality of life was recorded through the administration of the OHIP-14 test, FACE-Q test scale and FACE-Q test. Comparison between the two groups was done using a nonparametric inferential statistical test, the Mann-Whitney U-test. The results showed no significant differences in terms of quality of life between the two groups. Patients treated with orthodontic first approach presented greater psychological distress and perceived their faces as unattractive. A worsening of the aesthetics of the face determined by the orthodontic approach before surgery, may not be decisive in the quality of life of patients, which will certainly be better after surgery. SFA and OFA determine in both cases a marked improvement in the patient's quality of life.

Time-efficient combined morphologic and quantitative joint MRI: an in situ study of standardized knee cartilage defects in human cadaveric specimens

BackgroundQuantitative techniques such as T2 and T1ρ mapping allow evaluating the cartilage and meniscus. We evaluated multi-interleaved X-prepared turbo-spin echo with intuitive relaxometry (MIXTURE) sequences with turbo spin-echo (TSE) contrast and additional parameter maps versus reference TSE sequences in an in situ model of human cartilage defects.MethodsStandardized cartilage defects of 8, 5, and 3 mm in diameter were created in the lateral femora of ten human cadaveric knee specimens (81 ± 10 years old; nine males, one female). MIXTURE sequences providing proton density-weighted fat-saturated images and T2 maps or T1-weighted images and T1ρ maps as well as the corresponding two- and three-dimensional TSE reference sequences were acquired before and after defect creation (3-T scanner; knee coil). Defect delineability, bone texture, and cartilage relaxation times were quantified. Appropriate parametric or non-parametric tests were used.ResultsOverall, defect delineability and texture features were not significantly different between the MIXTURE and reference sequences (p ≤ 0.47). After defect creation, relaxation times significantly increased in the central femur (T2pre = 51 ± 4 ms [mean ± standard deviation] versus T2post = 56 ± 4 ms; p = 0.002) and all regions combined (T1ρpre = 40 ± 4 ms versus T1ρpost = 43 ± 4 ms; p = 0.004).ConclusionsMIXTURE permitted time-efficient simultaneous morphologic and quantitative joint assessment based on clinical image contrasts. While providing T2 or T1ρ maps in clinically feasible scan time, morphologic image features, i.e., cartilage defects and bone texture, were comparable between MIXTURE and reference sequences.Relevance statementEqually time-efficient and versatile, the MIXTURE sequence platform combines morphologic imaging using familiar contrasts, excellent image correspondence versus corresponding reference sequences and quantitative mapping information, thereby increasing the diagnostic value beyond mere morphology.Key points• Combined morphologic and quantitative MIXTURE sequences are based on three-dimensional TSE contrasts.• MIXTURE sequences were studied in an in situ human cartilage defect model.• Morphologic image features, i.e., defect delineabilty and bone texture, were investigated.• Morphologic image features were similar between MIXTURE and reference sequences.• MIXTURE allowed time-efficient simultaneous morphologic and quantitative knee joint assessment.Graphical

Improvement of absorbability, osteoconductivity, and strength of a β-tricalcium phosphate spacer for opening wedge high tibial osteotomy: clinical evaluations with 106 patients

BackgroundAn ideal synthetic spacer for medial opening wedge high tibial osteotomy (MOWHTO) has not yet been developed. The authors have developed a new β-tricalcium phosphate (β-TCP) spacer with 60% porosity (N-CP60) by modifying the micro- and macro-pore structures of a conventional β-TCP spacer (CP60) that is widely used in clinical practice. The purpose of this study was to compare the absorbability, osteoconductivity, and in vivo strength of the N-CP60 spacer with those of the CP60 spacer, when used in MOWHTO.MethodsFirst, the porosity, diameter distribution of macro- and micropores, and compressive strength of each β-TCP block were examined using methodology of biomaterial science. Secondly, a clinical study was performed using a total of 106 patients (106 knees) with MOWHTO, who were followed up for 18 months after surgery. In these knees, the N-CP60 and CP-60 spacers were implanted into 49 tibias and 57 tibias, respectively. The absorbability and osteoconductivity were radiologically evaluated by measuring the area of the implanted spacer remaining unabsorbed and assessing with the Hemert’s score, respectively. The incidence of cracking in the implanted spacers was determined using computed radiography. Statistical comparisons were made with non-parametric tests. The significance level was set at p = 0.05.ResultsThe N-CP60 and CP60 blocks had almost the same porosity (mean, 61.0% and 58.7%, respectively). The diameter of macropores was significantly larger (p < 0.0001) in the N-CP60 block than in the CP60 block, while the diameter of micropores was significantly smaller (p = 0.019) in the N-CP60 block. The ultimate strength of the N-CP60 block (median, 36.8 MPa) was significantly greater (p < 0.01) than that of the CP60 block (31.6 MPa). As for the clinical evaluations, the absorption rate of the N-CP60 spacer at 18 months after implantation (mean, 48.0%) was significantly greater (p < 0.001) than that of the CP60 spacer (29.0%). The osteoconductivity of the N-CP60 spacer was slightly but significantly higher (p = 0.0408) than that of the CP60 spacer only in zone 1. The incidence of in vivo cracking of the posteriorly located N-CP60 spacer at one month (mean, 75.5%) was significantly lower (p = 0.0035) than that of the CP60 spacer (91.2%).ConclusionsThe absorbability, osteoconductivity, and compressive strength of the new N-CP60 spacer were significantly improved by modifying the macro- and micro-pore structures, compared with the conventional CP60 spacer. The N-CP60 spacer is more clinically useful than the CP60 spacer.Trial registration numberH29-0002.

Ethnocultural empathy development of future language teachers through digital multiliteracy resources for low-literacy adult migrants.

A mixed-method pre-post study was conducted with 48 trainee teachers who participated in stand-alone digital multiliteracy interventions, in which they were encouraged to envisage themselves as future teachers of low-literate migrants. Policy documents such as the reference guide on Literacy and Second Language Learning for the Linguistic Integration of Adult Migrants, journal articles, audiovisual resources as well as examples of existing educational materials aimed at the target audience, were made available to them on an online platform. In two separate studies, trainees were encouraged to collaboratively produce two different multimodal outputs. The Revised Scale of Ethnocultural Empathy was administered before and after the intervention, subjecting the data obtained to quantitative analysis. Qualitative data was also collected to gain a better understanding of the affective and cognitive processes experienced by the participants. Simple statistical analysis coupled with the comparison of means was used to respond to the research questions. Statistical hypothesis testing, including correlations and non-parametric statistics were used to analyze the relationship between each of the factors within the RSEE and the participants, considering the different interventions applied. Non-parametric tests (U-Mann Whitney) were used to compare the differences between the levels of ethnocultural empathy of the participants in the two studies. Significant differences were found in Factor 3 (Empathy) and Factor 5 (Anxiety) between the groups and their post-intervention results, with a p value of 0.053 and 0.038, respectively. The effect size r was calculated, obtaining a size effect of 0.625 for Factor 3 (Empathy) and 0.674 for Factor 5 (Anxiety). These results indicate that the significant differences and the size effect between both groups are large. U-Mann Whitney non-parametric analysis also revealed gender differences in Factor 3 (Empathy), showing females higher levels than males. Effect size r analysis showed a large size effect of 0.708 for Factor 3 (Empathy). The findings pertaining to gender-related differences in empathy levels confirm the conclusions drawn by previous studies. When contrasting study 1 and 2, statistical differences were also shown after the intervention for the 'Anxiety and Lack of Multicultural Self-efficacy' factor. The qualitative data analysis was carried out with Atlas.ti v.8, in order to isolate and categorize the broader themes and the most significant explanatory quotes extracted from the participants' records and interviews. The results reveal the learning strategies that each group of learners applied to successfully complete the task at hand, as well as the participants' deployment of their critical thinking skills and the awakening of a sense of awareness of their own professional competence development process. This study set out to compare how effective two digital multiliteracy interventions were in developing future language teachers' ethnocultural empathy and cognitive abilities when appraising the educational needs of low-literacy migrants. Despite the small sample size, the study certainly adds to our understanding of the impact of multimodal tasks involving critical thinking skills on trainees' cognitive and affective abilities. Besides, it expands the growing body of research that points to the desirability of embedding digitally-based content creation tasks in training curricula for future language teachers.

Original Research: Nurses' Knowledge and Attitudes Regarding the Sustainable Development Goals: A Global Study.

Nurses have a critical role to play in achieving the United Nations' 17 Sustainable Development Goals (SDGs). While Goal 3 (good health and well-being) is of particular importance to nursing, every SDG contributes to the advancement of universal health and well-being. Yet many nurses are unfamiliar with the SDGs and how they relate to everyday nursing practices. The purpose of this study was to examine RNs' knowledge of and attitudes toward the SDGs. This study used a descriptive correlational cross-sectional design. A convenience sample of RNs from multiple countries completed an anonymous online survey that included eight demographic items and 25 items exploring participants' knowledge of and attitudes toward the SDGs. Descriptive, parametric, and nonparametric statistics were used to analyze the data. The majority of nurses in this study perceived themselves as lacking knowledge of the SDGs. Most wanted to know more, including how they could take action to help achieve the goals. Overall, participants agreed that the SDGs are relevant to nursing practice and that nurses are integral to their advancement. Participants who were younger than age 50, those living in the United States, and those who practiced primarily in a clinical or community setting were more likely than others to self-report lower SDG knowledge scores. The study findings contribute to our collective understanding of RNs' knowledge and attitudes regarding the SDGs. They can assist nurse educators and leaders worldwide in developing targeted strategies to better inform nurses and prepare them for actions that will advance these goals. Increasing nurses' knowledge of the SDGs, especially as these goals relate to daily clinical practice, may lead to greater nursing engagement and impact.

Do systemic amoxicillin and metronidazole during the non-surgical peri-implantitis treatment phase prevent the need for future surgical treatment? A retrospective long-term cohort study.

The aim of this retrospective long-term follow-up of a 3-month RCT was to assess whether non-surgical peri-implantitis treatment with adjunctive systemic antibiotics influenced the need for additional surgical treatment. Patients enrolled in an aftercare programme following non-surgical peri-implantitis treatment, with or without systemic amoxicillin and metronidazole, were analysed. Data had previously been collected pre-treatment (T0) and 3 months after treatment (T1) and were additionally collected during subsequent aftercare visits, until the final assessment (T2). Primary outcome was the need for additional surgical peri-implantitis therapy during the aftercare programme, analysed via Kaplan-Meier analysis and Cox regression. Secondary outcomes involved clinical parameters, assessed using parametric and non-parametric tests. Forty-five patients (22 AB- group, 23 AB+ group) were included. The mean follow-up time between T1 and T2 was 35.9 months (SD = 21.0). 73.9% of the AB+ group and 50.0% of the AB- group did not receive additional surgical therapy (log-rank test, p = .110). The adjusted Cox regression model did not provide a significant result for antibiotics (β = .441, 95% CI = 0.159-1.220, p = .115). Univariable regression analysis highlighted the influence of baseline peri-implant pocket depth on the need for surgical treatment (β = 1.446, 95% CI = 1.035-2.020, p = .031). Systemic amoxicillin and metronidazole administered during non-surgical peri-implantitis treatment do not seem to prevent the need for additional surgical therapy in the long term, during a structured aftercare programme.

Effects of sodium intake, age, gender, blood sampling time on distribution of plasma aldosterone, renin activity, deoxycorticosterone, cortisol, cortisone, and 24 h urinary aldosterone levels in normotensive individuals based on LC-MS/MS.

This study aims to analyze the distribution of plasma aldosterone, renin activity, deoxycorticosterone (DOC), cortisol, cortisone, and 24 h urinary aldosterone (24 h-uAld) levels based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Plasma and 24 h urine were collected from 129 healthy volunteers in Northeast China. The effect of sodium intake, age, gender, blood sampling time on plasma aldosterone concentration (PAC), plasma renin activity (PRA), PAC to PRA ratio (ARR), DOC, cortisol, cortisone, cortisol to cortisone ratio, and 24 h-uAld were investigated by nonparametric test, multiple linear regression and Harris-Boyd's standard deviate test. There was no significant difference observed in 24 h-uAld, PAC (AM), PRA(AM), ARR (AM), DOC (AM), cortisol (AM), cortisone (AM), and cortisol to cortisone (AM) between high and low sodium intake group. Significant differences were observed between morning and afternoon sampling groups in terms of PAC, ARR, DOC, cortisol, and cortisone. Reference intervals (RIs) of 24 h-uAld, PAC (AM) were recommended to be partitioned by gender. RI of PRA was recommended age stratification. We recommend that the same reference interval could be used regardless of sodium intake. Gender is the main influence factor for 24 h-uAld, PAC, and ARR. Age is key influence factor for PRA.

Implementation of shared decision-making about rooming-in: A before and after an audit of breastfeeding in Taiwan

BackgroundThe 24-h rooming-in policy is crucial to the Baby-Friendly Hospital Initiative (BFHI) for promoting breastfeeding. However, this policy may restrict maternal autonomy. In 2018, to integrate women’s preferences into care decisions, Taiwan’s Baby-Friendly certification included prenatal shared decision-making (SDM) for rooming-in. Prior to 2018, maternal knowledge, considerations, and intentions regarding rooming-in and the impact of prenatal SDM were unknown.MethodsA retrospective electronic medical record cohort study was conducted in southern Taiwan. Data on healthy postpartum women eligible for rooming-in and breastfeeding for the years 2017 and 2019, reflecting the periods before and after prenatal SDM was introduced, were gathered. Maternal and newborn characteristics, maternal knowledge, considerations, and prenatal intentions for postpartum rooming-in and breastfeeding during hospitalization were collected. Additionally, data on actual postpartum rooming-in practices during hospitalization and exclusive breastfeeding (EBF) practices from birth to hospital discharge, to 1 month, and to 2 months postpartum were collected. Descriptive and non-parametric statistics were applied to analyze the data.ResultsA total of 621 women in 2017 and 311 women in 2019 were included. After prenatal SDM was introduced, the rooming-in rate during hospitalization fell from 42.2% in 2017 to 25.6% in 2019 (p < 0.001), and the EBF rate declined from 45.9% to 35.7% (p = 0.01). Additionally, the 1-month postpartum EBF rate decreased from 46.4% in 2017 (n = 571) to 44.3% in 2019 (n = 264), and the 2-month postpartum EBF rate dropped from 45.5% in 2017 (n = 591) to 40.2% (n = 308). According to the 2019 Patient Decision Aids responses (n = 236), women demonstrated limited understanding of rooming-in, with only 40.7% expressing an intention toward 24-h rooming-in. Women of older maternal age (p < 0.001), with a graduate degree (p = 0.02), full-time employment (p = 0.04), and concerns about rest disruption (p < 0.001), were more likely to prefer non-24-h rooming-in.ConclusionsInitiatives must promote prenatal SDM to enable healthcare providers to address misconceptions and tailor education, thereby increasing women’s intention toward 24-h rooming-in and EBF. Future research should explore women’s experiences and unmet needs at BFHI facilities to inform the construction of a baby- and mother-friendly environment.

Quality of Life Outcomes for Parotid Malignancies.

This study describes patient-reported outcome measures (PROMs) and associated factors in patients who underwent surgery for malignant parotid tumors (MPT). This is a retrospective study of all surgically treated MPT patients in a multidisciplinary head and neck cancer (HNC) survivorship clinic (2017-2023). PROMs included University of Washington Quality of Life Questionnaire (UW-QOL), Eating Assessment Tool (EAT-10), Patient Health Questionnaire (PHQ-8), Generalized Anxiety Disorder (GAD-7), Neck Disability Index (NDI), and Insomnia Severity Index. Multivariable regression analysis was used to investigate clinical predictors associated with PROMs. In 62 MPT patients, the prevalence of clinically relevant dysphagia symptoms (EAT-10), elevated symptoms of depression (PHQ-8), moderate/severe symptoms of anxiety (GAD-7), moderate/severe neck pain with activities of daily living (NDI), and moderate/severe symptoms of insomnia at last follow-up was 32.3%, 15.5%, 7.1%, 17.7%, and 7.2%, respectively. Nonparametric one-sided test revealed that patients treated with adjuvant CRT had significantly worse physical QOL, social-emotional QOL, and swallowing scores than patients treated with surgery alone (p = 0.01, p = 0.02, p = 0.03, respectively); that patients treated with surgery and adjuvant RT had significantly worse physical QOL and social-emotional QOL than patients treated with surgery alone (p < 0.01, p = 0.01, respectively) and that patients treated with surgery and adjuvant CRT had significantly worse swallowing and neck pain than patients treated with surgery and adjuvant RT (p = 0.03, p = 0.05, respectively). In patients with surgically treated MPT, adjuvant CRT and RT were associated with worse PROMs. 4 Laryngoscope, 2024.

Mineral resource management for a sustainable future: Unraveling the role of energy tax in driving green technologies and environmental quality

Effective mineral resource management balances economic growth with environmental sustainability and ensures long-term resource availability. The effectiveness of energy taxes in achieving carbon reduction has been a subject of considerable debate in sustainable development. Environmental taxation (ERT) is expected to promote decreasing carbon emissions by incentivizing the development of green technical advancements, which are crucial for achieving environmental sustainability. This research expands the current discourse on sustainable theory, specifically examining the influence of green energy, energy taxes, and socioeconomic factors on Chile's greenhouse gas (GHG) emissions. This analysis is based on quarterly data from 1994 to 2021. The nonlinearity test findings were supported using nonlinear approaches, such as quantile-on-quantile regression (QQR), nonparametric quantile causality analysis, and time-varying nonparametric causality evaluation. The QQR study findings indicate that the combination of green technology, green energy, energy taxes, and socioeconomic factors leads to decreased greenhouse gas (GHG) emissions in Chile, as shown across most quantiles. Furthermore, the dynamic nonparametric causality analysis results revealed substantial causative connections between green technology, green energy, energy taxes, and socioeconomic situations at different time intervals and levels of measurement. These findings serve as the basis for initiating policies.

The UF-5000 Atyp.C parameter is an independent risk factor for bladder cancer

Bladder carcinoma (BC) accounts for > 90% of all urothelial cancers. Pathological diagnosis through cytoscopic biopsy is the gold standard, whereas non-invasive diagnostic tools remain lacking. The “Atyp.C” parameter of the Sysmex UF-5000 urine particle analyzer represents the ratio of nucleus to cytoplasm and can be employed to detect urinary atypical cells. The present study examined the association between urinary Atyp.C values and BC risk. This two-center, retrospective case–control study identified clinical primary or newly recurrent BC (study period, 2022–2023; n = 473) cases together with controls with urinary tract infection randomly matched by age and sex (1:1). Urinary sediment differences were compared using non-parametric tests. The correlations between urinary Atyp.C levels and BC grade or infiltration were analyzed using Spearman’s rank correlation. The BC risk factor odds ratio of Atyp.C was calculated using conditional logistic regression, and potential confounder effects were adjusted using stepwise logistic regression (LR). Primary risk factors were identified by stratified analysis according to pathological histological diagnosis. The mean value of urinary Atyp.C in BC cases (1.30 ± 3.12) was 8.7 times higher than that in the controls (0.15 ± 0.68; P < 0.001). Urinary Atyp.C values were positively correlated with BC pathological grade and invasion (r = 0.360, P < 0.001; r = 0.367, P < 0.001). Urinary Atyp.C was an independent risk factor for BC and closely related with BC pathological grade and invasion. Elevated urinary Atyp.C values was an independent risk factor for BC. Our findings support the use of Atyp.C as a marker that will potentially aid in the early diagnosis and long-term surveillance of new and recurrent BC cases.

The relationship between sedentary lifestyle, neck disability, and high blood pressure among bankers

Background: A sedentary lifestyle greatly affects a person's life. Inactive lifestyle changes can result in increased neck disability. Sedentary behavior can also affect vascular, metabolic, and autonomic systems. This study aimed to determine the relationship between a sedentary lifestyle, neck disability, and high blood pressure in bank employees. Methods: The research method used is an observational analytical study with a cross-sectional approach and a sampling technique, namely purposive sampling. The number of samples obtained was 93 samples aged 18-55 years. The independent variable measured was sedentary lifestyle using the International Physical Activity Questionnaire (IPAQ) questionnaire. The dependent variables measured were neck disability using the Neck Disability Index (NDI) questionnaire and high blood pressure measured using a sphygmomanometer. Results: Based on the non-parametric Spearman Rho test, a value of p = 0.001 (p &lt; 0.05) was obtained, which showed that there was a significant relationship between a sedentary lifestyle and neck disability and high blood pressure and the value of the correlation coefficient ranging from r = -0.831 to -0.928 and negative values indicating an undirected relationship with a very high level of correlation. Based on the results of multivariate analysis with regression logistic tests showed a significant relationship between a sedentary lifestyle and neck disability and high blood pressure characterized by p values &lt; 0.05. Conclusion: Based on the study's results, there is a negative relationship between a sedentary lifestyle and neck disability and high blood pressure in bank employees. When a sedentary lifestyle shows low measurement results, it will indicate that the individual has a neck disability and high blood pressure.

Comparison of the clinical effectiveness of Class IV Laser therapy and therapeutic ultrasound in patients with chronic neck pain: a randomized controlled trial

INTRODUCTION: Chronic neck pain (CNP) is a common musculoskeletal problem that affects a large proportion of the population and lasts longer than three months. It has a high cost in terms of life, disability, and healthcare. Several modalities have effectively provided immediate and long-term relief for CNP; however, the comparative clinical effectiveness of these modalities is limited. OBJECTIVES: The study aimed to determine the clinical effectiveness of Class IV Laser therapy and Therapeutic Ultrasound (TUS) in patients with CNP. METHODS AND MATERIALS: Forty-four patients with CNP of both genders were recruited from an age range of 20–45 years from the Department of Musculoskeletal Physiotherapy of Maharishi Markandeshwar Institute of Physiotherapy, MM(DU), Ambala, India. They were divided into two groups at random: the LASER group A (n = 22) and the TUS group B (n = 22). The intervention duration was 2 weeks with 6 treatment sessions. Pre- and post-treatment outcome measures were assessed with the Visual Analog Scale (VAS), Algometer, Goniometer, and Neck Disability Index (NDI) questionnaires at baseline and after 2 weeks of intervention. The LASER group received a target dose of 10 joules per cm2 at a power of 10 watts, with a continuous dosage frequency. The TUS group underwent a continuous mode ultrasound (3 MHz, 1 W/cm2) for 6 minutes. The Shapiro-Wilk test was used to assess the normality of the data. For parametric and non-parametric data analysis within the group, the paired t-test and Wilcoxon signed rank were used. The independent t-test and Mann-U Whitney test were used for the group comparison of parametric and non-parametric data, respectively. RESULTS: In both groups, there was a significant improvement in all the outcome measures (p&lt;0.001). There was a statistically significant difference between the two interventions in VAS, Pain Pressure Threshold (PPT), and NDI (p&lt;0.05). CONCLUSION: Class IV Laser therapy is clinically more effective than therapeutic ultrasound in treating patients with chronic neck pain.

The Androgen Dehydroepiandrosterone Sulfate Shows a Greater Relationship with Impulsivity than Testosterone in a Healthy Male Sample.

This study was designed to examine the relationships among the impulsivity construct as a personality trait, the dehydroepiandrosterone sulfate (DHEA-S), and testosterone in a sample of 120 healthy middle-aged males (Mage = 44.39; SD = 12.88). The sum of the three BIS-11 scales, the SR, and the five UPPS-P scales correlated with DHEA-S 0.23 (p < 0.006) and testosterone 0.19 (p < 0.04), controlling for age. Partial correlations showed that DHEA-S was significantly related to motor impulsivity (0.24; p < 0.008), Sensitivity to Reward (0.29; p < 0.002), Lack of Premeditation (0.26; p < 0.05), and, to a lesser extent, Sensation Seeking (0.19; p < 0.04) and Positive Urgency (0.19; p < 0.04). Testosterone correlated with attention impulsivity (0.18; p < 0.04), Sensation Seeking (0.18; p < 0.04), and Positive Urgency (0.22; p < 0.01). Sensitivity to Reward, Negative Urgency, and Positive Urgency were significant predictors of DHEA-S (R2 = 0.28), and Positive Urgency for testosterone (R2 = 0.09). Non-parametric LOESS graphical analyses for local regression allowed us to visualize the non-linear relationships between the impulsivity scales with the two androgens, including non-significant trends. We discuss the implications of these results for impulsive biological personality traits, the limitations of our analyses, and the possible development of future research.

Empowering gynaecologists with Artificial Intelligence: Tailoring surgical solutions for fibroids

BackgroundIn recent years, the integration ofArtificial intelligence (AI) into various fields of medicine including Gynaecology, has shown promising potential. Surgical treatment of fibroid is myomectomy if uterine preservation and fertility are the primary aims.AI usage begins with the involvement of LLM (Large Language Model) from the point when a patient visits a gynecologist, from identifying signs and symptoms to reaching a diagnosis, providing treatment plans, and patient counseling. ObjectiveUse of AI (ChatGPT versus Google Bard) in the surgical management of fibroid. Study designIdentifyingthe patient’s problems using LLMs like ChatGPT and Google Bard and giving a treatment optionin 8 clinical scenarios of fibroid. Data entry was done using M.S. Excel and was statistically analyzed using Statistical Package for Social Sciences (SPSS Version 26) for M.S. Windows 2010. All results were presented in tabular form. Data were analyzed using nonparametric tests Chi-square tests or Fisher exact test.pvalues < 0.05 were considered statistically significant. The sensitivity of both techniques was calculated. We have used Cohen’s Kappa to know the degree of agreement. ResultsWe found that on the first attempt, ChatGPT gave general answers in 62.5 % of cases and specific answers in 37.5 % of cases. ChatGPT showed improved sensitivity on successive prompts 37.5 % to 62.5 % on the third prompt. Google Bard could not identify the clinical question in 50 % of cases and gave incorrect answers in 12.5 % of cases (p = 0.04). Google Bard showed the same sensitivity of 25 % on all prompts. ConclusionAI helps to reduce the time to diagnose and plan a treatment strategy for fibroid and acts as a powerful tool in the hands of a gynecologist. However, the usage of AI by patients for self-treatment is to be avoided and should be used only for education and counseling about fibroids.

Bridging the Gap between Psychophysiological and Audiological Factors in the Assessment of Tinnitus: An EEG Investigation in the Beta Band.

Despite substantial progress in investigating its psychophysical complexity, tinnitus remains a scientific and clinical enigma. The present study, through an ecological and multidisciplinary approach, aims to identify associations between electroencephalographic (EEG) and psycho-audiological variables. EEG beta activity, often related to stress and anxiety, was acquired from 12 tinnitus patients (TIN group) and 7 controls (CONT group) during an audio cognitive task and at rest. We also investigated psychological (SCL-90-R; STAI-Y; BFI-10) and audiological (THI; TQ12-I; Hyperacusis) variables using non-parametric statistics to assess differences and relationships between and within groups. In the TIN group, frontal beta activity positively correlated with hyperacusis, parietal activity, and trait anxiety; the latter is also associated with depression in CONT. Significant differences in paranoid ideation and openness were found between groups. The connection between anxiety trait, beta activity in the fronto-parietal cortices and hyperacusis provides insights into brain functioning in tinnitus patients, offering quantitative descriptions for clinicians and new multidisciplinary treatment hypotheses.

Comparing clinical measures of near point of convergence and accommodation from the lateral canthus and browline in a paediatric and adolescent population.

Clinicians measure the near point of convergence (NPC) and the amplitude of accommodation (AA) from the spectacle plane, the bridge of the nose or the lateral canthus when assessing visual function. These values are compared to standard clinical criteria to diagnose vergence and accommodation deficits, despite varying reference points. This prospective study explored measuring relative to the spectacle plane and from the lateral canthus for NPC and monocular AA, and the resulting clinical implications of diagnosing visual deficits. Participants were seen by a single clinician for an eye examination. NPC was measured from the forehead and the lateral canthus of the right eye. Monocular AA was measured from the brow and the lateral canthus. Differences between measurements were analysed using non-parametric statistical tests including Wilcoxon Signed Rank, as well as linear regression and a linear mixed effects model to adjust for inter-eye correlation and repeated measures. Chi-square tests were used to assess differences in rates of abnormal findings. Data were collected from 70 participants (53% female, median age 13 [11-15] years). On average, measuring NPC from the lateral canthus yielded a value 1.8 cm higher than measuring from the forehead. Measuring AA from the lateral canthus resulted in an average difference of 1.5 cm compared to measuring from the brow. A total of 39% and 76% of subjects failed NPC compared to clinical norms when measured from the forehead or the lateral canthus, respectively, while 7% and 40% failed AA when measured from the brow or the lateral canthus, respectively. With the variable anatomy of the eye, it is imperative to account for the measurement point when assessing visual function. Measuring from the lateral canthus greatly increased the failure rates for NPC and AA compared with measuring from the forehead and brow, respectively.

Healthcare Worker's Satisfaction Assessment for a Healthcare Adverse Event Reporting Framework and the Management Approach for Such Reporting in the Emergency Department of Rural Government Hospitals.

The healthcare adverse event (HAE) reporting framework is more than just a tool. It is a crucial pillar in our pursuit of patient safety, quality improvement, trust maintenance, regulatory compliance, and ethical standards in healthcare delivery. To assess healthcare workers' satisfaction with the HAE reporting framework and the management approach towards such reporting in the emergency department of rural government hospitals by conducting a satisfaction survey. This prospective observational research was conducted in the Department of Emergency Medicine of the Uttar Pradesh University of Medical Sciences, Saifai, and adjoining district hospitals from November 2023 to January 2024. The study involved 320 healthcare professionals working in the emergency department. The quantitative survey research used a questionnaire and a quality Likert scale response.The data were analyzed on an ordinal measurement scale using nonparametric statistical methods. The sample data were analyzed using frequency tables, percentage pie charts, and comparison bar graphs. In nonparametric statistical tests, the one-sample Wilcoxon signed rank test was used to infer the population's central tendency, and the Kruskal-Wallis testwas used to make inferences about the population categories. The satisfaction of healthcare professionals with the HAE reporting framework and the management approach was diverse. When surveyed about the HAE reporting framework in the emergency department, out of the 320 healthcare professionals,50% (161) expressed dissatisfaction,47% (149) were satisfied, and 3% (10) did not comment. Paramedics were most dissatisfied (61% of 133). When asked about the management approach while dealing with such reporting, 50% (159) were satisfied, 46% (147) were unsatisfied, and 4% (14) did not comment. On comparingprofessions, 43% (29) of 33 doctorsand 62% (83) of 133 paramedics were unsatisfied, giving a poor response. Additionally, 61% (72) of the 119 nursing staff were satisfied. The non-parametric inferential tests yielded a p-value of less than 0.001 for both questions, indicating a notable difference in the population's response to the HAE reporting framework and management approach. On pairwise comparison, there was a significant difference in perception (p<0.001) between the occupation groups, except for doctors and paramedics (p = 0.638) in the HAE reporting framework. By encouraging reporting, standardizing processes, analyzing incidents thoroughly, and using data-driven insights to inform improvement efforts, healthcare organizations can enhance patient safety, improve quality of care, and prevent future adverse events. The management approach to HAE reporting involves fostering a culture of safety and transparency, implementing standardized reporting systems, providing education and training to healthcare staff, establishing feedback mechanisms, conducting robust analysis of reported events, promoting continuous improvement, and ensuring transparency and accountability.
