ABSTRACT

BACKGROUND: Considering the importance of cardiac rehabilitation after coronary artery bypass grafting (CABG) and the development of acupuncture over the past few decades, the aim of this study was to evaluate the effects of acupuncture on patients’ exercise tolerance, heart rate and blood pressure after CABG.

METHODS: Thirty-four patients with a history of recent CABG were recruited between 2019 and 2020 for this clinical trial and randomly divided into two groups receiving acupuncture plus cardiac rehabilitation (group A) and cardiac rehabilitation alone (group B). In both groups, exercise-based rehabilitation exercise was performed. Group A additionally received acupuncture at PC6, PC4, HT7 and GB20 bilaterally. Changes in blood pressure, heart rate and Borg scale score were evaluated before, during and after the course of the treatment.

RESULTS: Heart rate was significantly lower in group A compared to group B after completion of the course of the treatment (P = 0.022). However, there were no statistically significant differences between the two groups in systolic or diastolic blood pressure or Borg scale scores (P > 0.05). Nevertheless, the Borg scale scores showed a significant decrease within each group over time (P < 0.001), reflecting an improvement in the patients’ ability to tolerate activity after cardiac rehabilitation with or without acupuncture.

CONCLUSION: Acupuncture in combination with exercise-based cardiac rehabilitation was more effective at decreasing heart rate than cardiac rehabilitation alone after CABG. Both approaches appeared to be similarly effective at improving exercise tolerance. In this study, the addition of acupuncture at the aforementioned traditional acupuncture point locations to exercise-based cardiac rehabilitation did not affect blood pressure.

ABSTRACT

INTRODUCTION/OBJECTIVES: The cost of medical services is a major barrier to healthcare accessibility for underserved populations in the United States. Community charity medical clinics help address this disparity by providing free or reduced-cost care for the medically underinsured; however, their economic and public health contributions are unknown. The objective of this study was to evaluate the scope of services and monetary impact of 4 community charity medical clinics in North Texas, with one of the largest medically underinsured populations in the United States.

METHODS: A cross-sectional study was conducted using electronic health records from 4 clinics serving adults and children in North Texas. Encounters from June 1 to December 31, 2018 completed by with sufficient documentation to assign a level of service were reviewed. There were 3942 encounters identified and 2148 (54.5%) audited. Centers for Medicare and Medicaid Services Evaluation and Management Standards were used to identify level of service provided for each encounter, and their subsequent value was determined based on CMS fee-for-service schedules at the time service was provided. Common conditions managed during these encounters were identified using ICD-10 codes documented with each encounter.

RESULTS: The most prevalent diagnoses encountered were hypertension, diabetes, hyperlipidemia, and major depressive disorder. We estimate the total value of services and medications provided for 1 year is between $840 278.30 to $845 737.41.

CONCLUSIONS: The charity clinics in North Texas provide a significant economic impact through a high level of charity care and a broad scope of services for a vulnerable patient population. The results may be used in the development and implementation of future services to meet the needs of the medically underinsured.

ABSTRACT

BACKGROUND: Branchial cleft cysts are pediatric congenital anomalies that can present as sinus tracts to the neck. Intraoperative methylene blue dye with fibrin glue has been suggested as an effective tool for tracking the tract’s depth to help definitively excise. In this large retrospective study of 118 patients spanning a decade, we aim to elucidate outcomes of branchial cleft anomaly excision without methylene blue dye.

METHODS: A retrospective review was conducted with patients who received branchial cleft anomaly (BCA) with sinus tract excision at Monroe Carrell Jr. Children’s Hospital from June 2012 to June 2022. We collected demographic variables, BCA characteristics, perioperative care variables (ie, prior drainage, imaging, and concurrent procedure), and perioperative outcomes (ie, intra- and post-operative complications). Median and interquartile range (IQR) were calculated for continuous demographic variables, and average and standard deviation (SD) were calculated for sinus tract length. Two-tailed Chi-square or Fisher’s exact tests were performed to compare categorical samples where applicable with a statistical significance threshold set a priori at P < .05, and multivariable logistic regression assessed significant associations.

RESULTS: The sample included 118 patients with an average tract length of 3.3 cm (SD = 1.7 cm). Incision/drainage was performed before definitive excision in 16 (13.6%) patients and was associated with age above the median (aOR = 5.29, 95% CI = 1.39-20.09, P = .015) and female sex (aOR = 3.81, 95% CI = 1.12-13.01, P = .032). Most patients (N = 85, 72.0%) did not receive imaging. Among 118 cases, 2 (1.7%) required return to the operating room for surgical site complications. No patients experienced intra-operative complications or tract recurrence necessitating revision surgery.

CONCLUSION: Patients with branchial cleft sinus tracts that were surgically excised without intraoperative dye achieved definitive resection with no recurrence and limited post-operative complications. While not a direct comparison, these results suggest that using intraoperative dye may be associated with unnecessary costs without benefit in outcomes.

ABSTRACT

BACKGROUND: The 22q11.2 deletion syndrome (22q11.2DS) entails intellectual disabilities and higher risk of psychotic disorders. Neurocognitive deficits predict real-life functioning of schizophrenic patients. We investigated real-life functioning in 22q11.2DS, aiming at defining how neurocognitive profile and psychopathological variables impact on psychotic patients’ social functioning.

METHODS: We recruited 63 patients with schizophrenia (SCZ, N = 63), 44 with 22q11.2DS (DEL, N = 44) and 19 with 22q11.2DS and psychosis (DEL-SCZ, N = 19), all matched for age, sex and neurocognitive profile; we administered the Positive and Negative Syndrome Scale (PANSS), the Brief Negative Symptom Scale (BNSS), the Specific Levels of Functioning (SLoF) scale and the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery (MCCB). We implemented descriptive analyses, MANCOVA and linear regression statistics.

RESULTS: The DEL-SCZ and the SCZ groups showed similar levels in Interpersonal Relationships (p = 0.093) and Social Acceptability subscales (p = 0.283). The DEL group scored higher on the Interpersonal Relationships subscale compared with the SCZ group (p = 0.001). The groups scored similarly on the other SLoF subscales. Both BNSS total score (beta = -0.343; p = 0.004) and BNSS asociality (beta = -0.487; p = 0.038) significantly predicted the Interpersonal Relationships variable in the groups with psychosis (SCZ and DEL-SCZ).

DISCUSSION AND CONCLUSIONS: Individuals with 22q11.2DS display a similar real-life functioning to patients with chronic schizophrenia. Social functioning impairments are typical of psychosis regardless of the genetic condition and highly predicted by negative symptoms like asociality. The 22q11.2DS represents a reliable biological model to study vulnerability to psychosis and its consequences on patients’ real-life and social functioning.

ABSTRACT

BACKGROUND: The recent trend in administering postoperative oral corticosteroids has proven effective in alleviating pain and improving surgical outcomes for hand and upper extremity procedures. However, concerns persist regarding potential infection risks despite a lack of supporting evidence in the current literature. We propose that a 6-day regimen of low-dose postoperative oral corticosteroids is safe and does not increase the likelihood of surgical site infections (SSIs) in adult upper extremity surgeries.

METHODS: A retrospective study of all adult patients who underwent clean, upper extremity surgery, including both soft tissue and hardware implantation cases, between November 2021 and November 2023, performed at a single institution were included in the study. Primary outcome measures were diagnosis of SSI by 14 days and 30 days. Categorical variables were compared using χ² tests, and continuous variables were compared using Wilcoxon rank-sum tests. A P value less than .05 was considered statistically significant.

RESULTS: A total of 813 cases were included for analysis-196 received a 6-day course of postoperative oral steroids (methylprednisolone) and 617 did not. Both groups had similar SSI rates of 4.1% and 3.1%, respectively, with no statistical differences between the groups at any postoperative time. Subgroup analysis of patients diagnosed with an SSI identified no statistically different demographic factors or medical comorbidities when comparing patients who received postoperative oral corticosteroids versus those who did not.

CONCLUSIONS: Low-dose, postoperative oral steroid use following adult upper extremity surgery is safe and does not increase the risk of SSI. Further investigations with prospective studies on postoperative oral corticosteroids would prove advantageous.

ABSTRACT

BACKGROUND: Transcranial direct current stimulation (tDCS) over the supplementary motor area (SMA) has shown promise in Tourette syndrome (TS), but previous studies were limited in size and stimulation duration.

OBJECTIVE: The aim was to explore the efficacy and safety of multiple sessions of cathodal tDCS over the bilateral SMA on tic severity in TS.

METHODS: A double-blind, randomized, sham-controlled trial 1 mA cathodal tDCS over bilateral SMA was performed in participants with TS older than 16 years. The intervention involved two 20-min periods of stimulation with either sham or active tDCS per day, over 5 consecutive days, during which participants actively suppressed tics. Tic severity was measured using the Yale Global Tic Severity Scale Total Tic Severity (YGTSS-TTS, primary outcome) score at baseline, day 5 (visit 5), and 1 week later (visit 6). Questionnaires focusing on comorbidities were performed at baseline and visit 6.

RESULTS: Twenty-four participants were randomly assigned (12 active, 12 sham; 8 women; median age: 26). We observed a significant effect of visit on YGTSS-TSS, but no significant effect of treatment or treatment × visit interaction emerged. In contrast, a statistically significant effect of the treatment × visit interaction was observed for the motor tic subscore, with significantly larger improvement in the active arm. Furthermore, we detected a significantly larger decrease in premonitory urge intensity at visit 6 after active stimulation. No effect was detected on severity of comorbidities.

CONCLUSIONS: This preliminary study suggests that bilateral tDCS over the SMA provides small, but significant benefits in reducing motor tic severity in TS.

ABSTRACT

BACKGROUND: Sound mathematical skills are paramount for effective nursing practice and patient safety.

OBJECTIVES: To explore the factors that influence nursing student anxiety when engaging with mathematics-related activities in nursing education.

DESIGN: A concurrent mixed methods employing cross-sectional online survey and focus group interviews.

SETTING: One undergraduate nursing course at an Australian university.

PARTICIPANTS: Bachelor of Nursing students from across academic years.

METHODS: An online survey comprising closed- and open-ended questions to assess mathematics anxiety and self-efficacy and associated factors affecting its application to practice. Focus group interviews to explore anxieties related to mathematics and students’ approaches to nursing mathematics. Quantitative data were analysed using descriptive statistics and qualitative data using inductive content analysis.

RESULTS: A total of 202 nursing students commenced the survey, of which 135 were fully completed, while 17 students participated in focus groups. Less than half were school leavers. Around three-quarters reported some level of fear of mathematics, while many lacked confidence, fear of making errors and/or harming patients and negative childhood experiences of mathematics. Survey items demonstrated extensive variation in perceptions.

CONCLUSIONS: The complexity and diversity of anxieties presents key challenges for nurse academics seeking to educate competent, safe students. Teaching approaches should be varied and consideration of having specialist mathematics teachers and learning psychologists on teaching teams to ensure student success.

REPORTING METHOD: This study is reported using Mixed Methods Reporting in Rehabilitation & Health Sciences (MMR-RHS).

PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

ABSTRACT

Chinese consumers are unfamiliar with the sensory attributes of wine and often pay more attention to the extrinsic attributes of wine that can most directly present information. Therefore, it is crucial to study consumer preferences for extrinsic attributes. This paper proposes a consumer segmentation method based on stratification and weighted clustering algorithm, leveraging data from an anonymous online survey (N = 3179). The AFR model is constructed based on the RFM model to segment wine consumers from the perspective of customer value. This model removes Monetary indicator and adds a new indicator Amount to eliminate multicollinearity caused by the Frequency and Monetary indicators of RFM model. In addition, factor analysis is used to assign weights to clustering indicators, addressing the problems of unequal weighting and strong correlation among the indicators. This allows for a simple, efficient, and precise segmentation of wine consumers at different levels. The method proposed in this article segments consumers into two layers and six categories: the potential layer includes product-oriented type, amorphous type, and cheap-fine type, while the mature layer comprises the rational type, reputation-price type and random type. This research will provide wine producers and distributors with a simple and efficient basis for production and marketing decision-making. Additionally, it can serve as a reference for consumer segmentation in food and other fields.

ABSTRACT

Foodborne diseases are a global burden. Actions to fight this group of diseases are necessary, especially for the younger demographic, which consists of consumers, food handlers, and the future workforce of the food chain. To this end, outlining the food safety profile of the target audience is imperative. Thus, this study aimed to understand and evaluate the risk perception, knowledge, and food safety self-reported practices of individuals between 5th and 9th grades (10 to 14 years old, considering the normal teaching flow) of public schools in the Federal District – Brazil. Instruments by Batista et al. (2023) and Brazil (2013) were used to achieve the objectives. The study included 1,420 students aged 9 to 17 (women = 50.6 %; n = 719) with a mean age of 11.9 years (±1.7) enrolled in 25 schools. It was observed that a more significant proportion of students attributed very low and low risk of Foodborne Diseases to the foods produced and served in School Food Services. The presence of optimistic bias, low perception of lethality, average knowledge, risky practices, and the gap between unsafe food knowledge and safe food handling/consumption practices were also identified. Correlations were identified between social vulnerability and risk perception (positive) and self-reported practices (negative). The results show the urgency of considering these individuals to ensure food safety, considering their vulnerability, reality, and the tools at their disposal.

ABSTRACT

Pesticide residues are identified as a significant food safety issue in Hami melons, and their rapid and accurate detection is deemed critical for ensuring public health. In response to the cumbersome procedures with existing chemical detection methods, this study explored the potential of identifying different pesticide residues in Hami melon by microfluorescence hyperspectral imaging (MF-HSI) technology combined with machine learning. By simulating the actual agricultural production, three pesticides, Beta-Cypermethrin, Difenoconazole, and Acetamiprid, were sprayed on Hami melons. The Hami melons with pesticide residues were collected as samples, from which spectral and image information were extracted. Competitive adaptive reweighted sampling (CARS), genetic algorithm (GA), and sequential projection algorithm (SPA) methods were used to extract characteristic wavelengths. Partial least squares discriminant analysis (PLS-DA), extreme learning machine (ELM), and k-nearest neighbor (KNN) classification models of the original spectra and characteristic wavelengths were established. 9 feature variables-Red (R), Green (G), Blue (B), Hue (H), Saturation (S), Value (V), Lightness (L), Red-Green axis (a) and Yellow-Blue axis (b) information was extracted by the color statistical method. 4 important color information of the image (G, B, V, L) were identified through Pearson correlation analysis, and the optimal feature wavelength was fused to enhance the identification accuracy of models. The results indicated that the SPA-PLS-DA model demonstrated the highest accuracy for the characteristic wavelength dataset, achieving accuracies of 89.35 % for the training set and 86.99 % for the testing set, which was better than the model established by the full wavelength dataset. Using the dataset that fuses feature wavelengths with 4 important image features, the SPA-PLS-DA model demonstrated superior performance, with recorded accuracy, precision, specificity, and sensitivity metrics on the testing set at 93.48 %, 93.81 %, 96.63 %, and 93.36 %, respectively. Consequently, MF-HSI technology combined with machine learning offers an approach to analyze pesticide residues in Hami melons accurately, and it provides a technical basis for detecting pesticide residues in other fruits and vegetables.
