ABSTRACT

This study aims to optimize the prediction model of personalized water pills that has been established by our research group. Dioscoreae Rhizoma, Leonuri Herba, Codonopsis Radix, Armeniacae Semen Amarum, and calcined Oyster were selected as model medicines of powdery, fibrous, sugary, oily, and brittle materials, respectively. The model prescriptions were obtained by uniform mixing design. With hydroxypropyl methylcellulose E5(HPMC-E5) aqueous solution as the adhesive, personalized water pills were prepared by extrusion and spheronizaition. The evaluation indexes in the pill preparation process and the multi-model statistical analysis were employed to optimize and evaluate the prediction model of personalized water pills. The prediction equation of the adhesive concentration was obtained as follows: Y_1=-4.172+3.63X_A+15.057X_B+1.838X_C-0.997X_D(adhesive concentration of 10% when Y_1<0, and 20% when Y_1>0). The overall accuracy of the prediction model for adhesive concentration was 96.0%. The prediction equation of adhesive dosage was Y_2=6.051+94.944X_A~(1.5)+161.977X_B+70.078X_C~2+12.016X_D~(0.3)+27.493X_E~(0.3)-2.168X_F~(-1)(R~2=0.954, P<0.001). Furthermore, the semantic prediction model for material classification of traditional Chinese medicines was used to classify the materials contained in the prescription, and thus the prediction model of personalized water pills was evaluated. The results showed that the prescriptions for model evaluation can be prepared with one-time molding, and the forming quality was better than that established by the research group earlier. This study has achieved the optimization of the prediction model of personalized water pills.

ABSTRACT

OBJECTIVES: To evaluate the prevalence of abnormal ECG findings and their association with imaging results in male Brazilian football players.

METHODS: The ‘B-Pro Foot ECG’ is a multicentre observational study conducted in 82 Brazilian professional clubs. It analysed 6125 players aged 15-35 years (2496 white, 2004 mixed-race and 1625 black individuals) who underwent cardiovascular screening from 2002 to 2023. All ECGs were reviewed by two experienced cardiologists in the athlete’s care. Those with abnormal findings underwent further investigations, including a transthoracic echocardiogram (TTE). Cardiac magnetic resonance (CMR) was subsequently performed based on TTE findings or clinical suspicion.

RESULTS: In total, 180 (3%) players had abnormal ECGs and 176 (98%) showed normal TTE results. Athletes aged 26-35 years had a higher prevalence of abnormal ECGs than younger athletes (15-25 years). Black players had a higher prevalence of T-wave inversion (TWI) in the inferior leads than white players (2.6% vs 1.4%; p=0.005), as well as in V5 (2.9%) and V6 (2.1%) compared with white (1.2% and 1.0%; p<0.001) and mixed-race (1.5% and 1.2%; p<0.05) players, respectively. TTE parameters were similar across ethnicities. However, four out of 75 players with inferolateral TWI showed abnormal TTEs and CMR findings consistent with cardiomyopathies. CMR also showed cardiomyopathies or myocarditis in four players with inferolateral TWI and normal TTEs. In total, nine (0.1%) athletes were diagnosed with cardiac diseases and were followed for 40±30 months, with no cardiac events documented.

CONCLUSION: This study found a 3% prevalence of abnormal ECGs in male Brazilian football players. Inferolateral TWI was associated with cardiac pathologies confirmed by CMR, even in athletes with a normal TTE.

ABSTRACT

Both ageing and hypertension are clinical factors that may lead to a higher propensity for dissection or rupture of ascending thoracic aortic aneurysms (ATAAs). This study sought to investigate effect of valve morphology on regional delamination strength of ATAAs in the elderly hypertensive patients. Whole fresh ATAA samples were harvested from 23 hypertensive patients (age, 71 ± 8 years) who underwent elective aortic surgery. Peeling tests were performed to measure region-specific delamination strengths of the ATAAs, which were compared between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV). The regional delamination strengths of the ATAAs were further correlated with patient ages and aortic diameters for BAV and TAV groups. In the anterior and right lateral regions, the longitudinal delamination strengths of the ATAAs were statistically significantly higher for BAV patients than TAV patients (33 ± 7 vs. 23 ± 8 mN/mm, p = 0.01; 30 ± 7 vs. 19 ± 9 mN/mm, p = 0.02). For both BAV and TAV patients, the left lateral region exhibited significantly higher delamination strengths in both directions than the right lateral region. Histology revealed that disruption of elastic fibers in the right lateral region of the ATAAs was more severe for the TAV patients than the BAV patients. A strong inverse correlation between longitudinal delamination strength and age was identified in the right lateral region of the ATAAs of the TAV patients. Results suggest that TAV-ATAAs are more vulnerable to aortic dissection than BAV-ATAAs for the elderly hypertensive patients. Regardless of valve morphotypes, the right lateral region may be a special quadrant which is more likely to initiate dissection when compared with other regions.

ABSTRACT

3D printed Poly Lactic Acid (PLA) bone plates exhibit limited three-point bending strength, restricting their viability in biomedical applications. The application of polydopamine (PDM) enhances the three-point bending strength by undergoing covalent interactions with PLA molecular structure. However, the heavy nature of PDM particles leads to settling at the container base at higher coating solution concentrations. This study investigates the impact of ultrasonic-assisted coating parameters on the three-point bending strength. Utilizing Response Surface Methodology (RSM) for statistical modeling, the study examines the influence of ultrasonic vibration power (UP), coating solution concentration (CC), and submersion time (TIME). RSM optimization recommended 100 % UP, 6 mg/ml CC, and 150 min TIME, resulting in maximum three-point bending strength of 83.295 MPa. Microscopic images from the comparative analysis revealed non-uniform coating deposition with mean thickness of 6.153 µm under normal coating. In contrast, ultrasonic-assisted coating promoted uniform deposition with mean thickness of 18.05 µm. The results demonstrate that ultrasonic-assisted coating induces PDM particle collision, preventing settling at the container base, and enhances three-point bending strength by 7.27 % to 23.24 % compared to the normal coating condition. This study emphasizes on the potential of ultrasonic-assisted coating to overcome the limitations of direct immersion coating technique.

ABSTRACT

BACKGROUND: Disparities in advance care planning (ACP) among older Latinos necessitate targeted interventions to enhance engagement and knowledge in end-of-life care. This study aimed to evaluate the effectiveness of a resource-efficient, culturally tailored educational intervention in improving ACP readiness and knowledge among older Latino adults in the community.

METHODS: A quasi-experimental pretest-posttest design was used to assess the impact of the intervention. The study involved community-dwelling older Latinos (aged 61-94) in the U.S. attending community wellness centers. Measures included participants’ knowledge of ACP, care options, familiarity with hospice and palliative care, and attitudes toward hospice, assessed using pre- and post-intervention surveys.

RESULTS: Statistically significant improvements were observed in ACP knowledge, understanding of care options, and attitudes towards hospice and palliative care post-intervention. Demographic factors influenced knowledge scores, with no significant gender differences in the intervention’s efficacy.

CONCLUSIONS: The educational intervention effectively enhanced end-of-life care planning readiness and knowledge among older Latinos. The study highlights the potential for sustainable, accessible, and culturally sensitive educational strategies to reduce disparities in ACP knowledge and possibly engagement.

ABSTRACT

OBJECTIVES: To observe the clinical effect and safety of auricular point sticking combined with periocular needle-embedding therapy for pseudomyopia and prevention of true myopia.

METHODS: A total of 269 children with pseudomyopia were randomized into an observation group (134 cases, 2 cases dropped out) and a control group (135 cases, 5 cases dropped out). In the control group, the healthy education was provided. In the observation group, besides the intervention as the control group, the auricular point sticking was delivered at gan (CO₁₂), pi (CO₁₃), xin (CO₁₅) and yan (LO₅) on one ear in each treatment, combined with periocular needle-embedding technique at bilateral Cuanzhu (BL 2), Yuyao (EX-HN 4) and Sibai (ST 2). There were 2 weeks of interval after 4 weeks of treatment. One course of treatment was composed of 6 weeks and 2 courses were required. Separately, before treatment, after 6 and 12 weeks of treatment, and after 12 weeks (the 1st follow-up visit) and 24 weeks (the 2nd follow-up visit) of treatment completion, the spherical equivalent (SE), SE progression, axial length (AL) progression, accommodative amplitude (AMP), the score of the TCM symptom and the general symptom were observed in the two groups. The safety and compliance were evaluated in the two groups.

RESULTS: After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, SE increased when compared with that before treatment in the two groups (P<0.05), and AMP was larger than that before treatment in the observation group (P<0.05). After 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the progression of SE was slower in the observation group compared with that in the control group (P<0.01, P<0.001). After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the progression of AL in the observation group was lower than that of the control group (P<0.05, P<0.01, P<0.001); and in the 1st and 2nd follow-up visits, AMP of the observation group was larger when compared with that in the control group (P<0.05, P<0.001). After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the total scores of TCM symptom and general symptom were reduced in comparison with those before treatment in the observation group (P<0.05); after 6 and 12 weeks of treatment, the total scores of TCM symptom and general symptom were lower than those before treatment in the control group (P<0.05). In the 1st and 2nd follow-up visits, the difference of the total score of TCM symptom and general symptom in the observation group was larger than that of the control group (P<0.05). In the observation group, compared with the control group, the scores for pale/dark complexion in the 1st and 2nd follow-up visits and that for lassitude in the 2nd follow-up visit were lower (P<0.05), the score for poor concentration after 12 weeks of treatment and that for poor sleep and memory in the 2nd follow-up visit were lower (P<0.05). There were no adverse reactions in the two groups. The compliance was 98.5% in the observation group and was 96.3% in the control group, without statistical difference (P>0.05).

CONCLUSIONS: On the basis of health education, auricular point sticking combined with periocular needle-embedding therapy can effectively prevent from true myopia, control the increase of SE, delay the growth of AL and improve AMP in children with pseudomyopia. This compound therapeutic regimen can relieve the general symptom and comprehensively prevent from myopia through multiple approaches, with high safety and satisfactory compliance.

ABSTRACT

OBJECTIVES: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative urinary function in elderly patients undergoing total hip arthroplasty (THA).

METHODS: One hundred and eighty elderly patients undergoing unilateral THA without indwelling urinary catheters were randomly assigned to a TEAS group (90 cases, 3 cases dropped out, 4 cases were eliminated) and a sham TEAS group (90 cases, 1 case dropped out, 4 cases were eliminated). Both groups received fascia iliac block and subarachnoid block anesthesia under ultrasound guidance. The patients in the TEAS group were treated with TEAS at Zhongji (CV 3), Guanyuan (CV 4), and bilateral Huiyang (BL 35), Ciliao (BL 32) 30 minutes before anesthesia initiation, with dissperse-dense wave, frequency of 2 Hz/100 Hz, until 30 minutes after surgery. The patients in the sham TEAS group underwent the same procedure with the device applied at the same acupoints but without electrical stimulation. The incidence of postoperative urinary retention (POUR), time to first void, voiding threshold, urinary adenosine triphosphate (ATP) level, postoperative abnormal voiding status (bladder residual volume, re-catheterization rate, nocturia occurrence), and postoperative incidence of urinary tract infection (UTI) and prosthetic joint infection (PJI) were observed in both groups.

RESULTS: The incidence of POUR in the TEAS group was lower than that in the sham TEAS group (P<0.05); the time to first void in the TEAS group was shorter than that in the sham TEAS group (P<0.05); the voiding threshold in the TEAS group was lower than that in the sham TEAS group (P<0.05); the urinary ATP level in the TEAS group was higher than that in the sham TEAS group (P<0.05); the bladder residual volume in the TEAS group was lower than that in the sham TEAS group (P<0.05); the nocturia occurrence in the TEAS group was lower than that in the sham TEAS group (P<0.05). However, there was no statistically significant difference in re-catheterization rate, incidence of UTI, and incidence of PJI between the two groups (P>0.05).

CONCLUSIONS: TEAS could effectively reduce the occurrence of postoperative urinary retention and improve the postoperative urinary function in elderly patients undergoing THA, which might be related with increasing the urinary ATP level.

ABSTRACT

OBJECTIVES: To observe the efficacy of napex acupoint thread-embedding combined with metoprolol tartrate tablet for prophylactic treatment of migraine without aura, and to compare its efficacy with simple napex acupoint thread-embedding and simple metoprolol tartrate tablet.

METHODS: A total of 105 patients with migraine without aura were randomized into a combination group (35 cases, 5 cases dropped out), a thread-embedding group (35 cases, 4 cases dropped out) and a western medication group (35 cases, 2 cases dropped out). In the thread-embedding group, napex acupoint thread-embedding was applied at bilateral Fengchi (GB 20) and points of 1.5 cun nearby to the lower edge of spinous process of cervical 2. In the western medication group, metoprolol tartrate tablet was given orally, 12.5 mg a time, twice a day. In the combination group, napex acupoint thread-embedding combined with oral metoprolol tartrate tablet was delivered. The treatment of 8 weeks was required in the 3 groups. The days of headache attacks, frequency of headache attacks, headache severity (visual analogue scale [VAS] score) and the migraine specific quality of life questionnaire version 2.1 (MSQ) score were observed during baseline period (4 weeks before treatment to before treatment), observation period (1-4 weeks and 5-8 weeks in treatment) and follow-up period (1-4 weeks after treatment completion) respectively, the proportions of the days of headache attacks/frequency of headache attacks relieved by 50% were calculated, and the safety was evaluated in the 3 groups.

RESULTS: During the observation period and the follow-up period, the days of headache attacks, frequency of headache attacks and headache VAS scores in the 3 groups were reduced compared with those of the baseline period (P<0.05). During the observation period and the follow-up period, the days of headache attacks and the frequency of headache attacks in the combination group were lower than those in the thread-embedding group and the western medication group (P<0.05); during the observation period (1-4 weeks in treatment), the headache VAS scores in the combination group and the thread-embedding group were lower than that in the western medication group (P<0.05); during the observation period (5-8 weeks in treatment) and the follow-up period, the headache VAS scores in the combination group were lower than those in the thread-embedding group and the western medication group (P<0.05). During the observation period and the follow-up period, the scores of role restriction, role prevention and emotion function of MSQ in the combination group were increased compared with those of the baseline period (P<0.05); during the observation period (5-8 weeks in treatment) and the follow-up period, the role prevention scores of MSQ in the thread-embedding group and the western medication group were increased compared with those of the baseline period (P<0.05); during the follow-up period, the emotion function scores of MSQ in the thread-embedding group and the western medication group were increased compared with those of the baseline period (P<0.05). During the observation period and the follow-up period, the scores of role restriction, role prevention and emotion function of MSQ in the combination group were higher than those in the thread-embedding group and the western medication group (P<0.05). There was no statistical difference in the proportions of the days of headache attacks/frequency of headache attacks relieved by 50% among the 3 groups (P>0.05), and there were no serious adverse reactions in the 3 groups.

CONCLUSIONS: Napex acupoint thread-embedding combined with metoprolol tartrate tablet, simple napex acupoint thread-embedding and simple metoprolol tartrate tablet all can reduce the days of headache attacks and the frequency of headache attacks, relieve headache severity and improve the quality of life in patients with migraine without aura. Napex acupoint thread-embedding combined with metoprolol tartrate tablet has a better effect.

ABSTRACT

BACKGROUND: Clozapine is the recommended treatment for managing treatment-resistant schizophrenia (TRS), and immunological mechanisms may be involved in its unique antipsychotic efficacy. This study investigated whether baseline immune abnormalities measured with blood cell count ratios can predict the clinical response after initiating treatment with clozapine in patients with clozapine naïve TRS.

METHODS: A longitudinal design was developed, involving 32 patients diagnosed with treatment-resistant, clozapine-naïve schizophrenia-spectrum disorder. Patients were evaluated at baseline before clozapine starting and 8 weeks of follow-up. Psychopathological status and immune abnormalities (blood cell count ratios: neutrophil-lymphocyte ratio [NLR], monocyte-lymphocyte ratio [MLR], platelet-lymphocyte ratio [PLR] and basophil-lymphocyte ratio [BLR]) were evaluated in each visit.

RESULTS: Baseline NLR (b=- 0.364; p=0.041) and MLR (b =- 0.400; p=0.023) predicted the change in positive symptoms over the 8-week period. Patients who exhibited a clinical response showed higher baseline NLR (2.38±0.96 vs. 1.75±0.83; p=0.040) and MLR (0.21±0.06 vs. 0.17±0.02; p=0.044) compared to non-responders. In the ROC analysis, the threshold points to distinguish between responders and non-responders were approximately 1.62 for NLR and 0.144 for MLR, yielding AUC values of 0.714 and 0.712, respectively. No statistically significant differences were observed in the blood cell count ratios from baseline to the 8-week follow-up.

CONCLUSION: Our study emphasizes the potential clinical significance of baseline NLR and MLR levels as predictors of initial clozapine treatment response in patients with TRS. Future studies with larger sample sizes and longer follow-up periods should replicate our findings.
