METHODS: PubMed and Scopus databases were searched based on PRISMA guideline to determine studies focusing on changes following NPC RT.
RESULTS: Eleven studies fulfilled the inclusion criteria. Microstructural changes occur most consistently in the temporal region. The changes were correlated with latency in seven studies; fractional anisotropy (FA) and gray matter (GM) volume remained low even after a longer period following RT and areas beyond irradiation site with reduced FA and GM measures. For dosage, only one study showed correlation, thus requiring further investigations.
CONCLUSION: DTI, DKI and VBM may be used as a surveillance tool in detecting brain microstructural changes of NPC patients which correlates to latency and brain areas following RT.
Methods: This school-based, non-randomised controlled study was conducted among secondary school students with a total of 236 respondents. The KAPS score were assessed before and 1 month after using self-administered validated KAPS questionnaire on TB. Analysis was done using repeated measures ANOVA.
Results: The mean percentage score (SD) for baseline knowledge, attitude, practice and stigma score for the respondents were 54.0 (4.48), 65.6 (1.74), 70.0 (1.43) and 66.0 (6.88), respectively. There was a significant difference (P < 0.001) in the knowledge and stigma score for intervention group compared to control group, adjusted for gender, ethnicity and smoking status 4 weeks post-TB educational programme. However, with regards to attitude and practice score, there was no significant difference (P = 0.210 and P = 0.243, respectively).
Conclusion: TB education programme was effective in improving knowledge and stigma related to TB. This health education programme can be used as one of the strategies for the prevention and control of TB in schools.
METHODS: A randomized trial was performed in a University hospital in Malaysia. Term women scheduled for labor induction, Bishop score ≤ 5, singleton, cephalic presentation, intact membrane, and reassuring pre-induction fetal heart rate tracing were recruited. Women with known gross fetal anomaly, allergy to latex and inability to consent or language difficulty were excluded. Participants were randomized to 16F, 22F, or 28F Foley catheter. Primary outcome was insertion failure and main secondary outcomes were insertion duration and pain (assessed by a Visual Numerical Rating Scale [VNRS] 0-10, higher score more pain). Analysis is done by analysis of variance (ANOVA), Kruskal-Wallis, and chi square test across the three arms and by t test and Mann-Whitney U test for pair wise comparisons.
RESULTS: One hundred twenty-seven participants' data were analyzed. The insertion failure 7/43(16%) versus 4/42(10%) versus 5/42(12%), p = 0.64, insertion duration median [IQR] 2.8 [1.8-4.8] versus 2.8 [1.7-3.7] versus 2.8 [1.7-4.3] min, p = 0.68 and insertion pain VNRS mean {SD} 4.2 {2.5} versus 3.4 {2.3} versus 3.6 {2.2}, p = 0.26, insertion to delivery interval 26.0 {9.7} versus 25.6 {9.1} versus 22.8 {7.4} h, p = 0.45, and spontaneous vaginal delivery 20/43 (45%) versus 23/42(55%) versus 25/42(60%), p = 0.48 for 16F versus 22F versus 28F arms, respectively. Pairwise comparisons were not different.
CONCLUSION: Foley catheter 16F versus 22F versus 28F resulted in similar digital insertion performance in the dorsal recumbent position for unripe cervix labor induction.
CLINICAL TRIAL REGISTRATION: https://doi.org/10.1186/ISRCTN21224268.
METHODS: A gender-matched case-control study was conducted in the largest public sector cardiac hospital of Pakistan, and the data of 460 subjects were collected. The dataset comprised of eight nonclinical features. Four supervised ML algorithms were used to train and test the models to predict the CVDs status by considering traditional logistic regression (LR) as the baseline model. The models were validated through the train-test split (70:30) and tenfold cross-validation approaches.
RESULTS: Random forest (RF), a nonlinear ML algorithm, performed better than other ML algorithms and LR. The area under the curve (AUC) of RF was 0.851 and 0.853 in the train-test split and tenfold cross-validation approach, respectively. The nonclinical features yielded an admissible accuracy (minimum 71%) through the LR and ML models, exhibiting its predictive capability in risk estimation.
CONCLUSION: The satisfactory performance of nonclinical features reveals that these features and flexible computational methodologies can reinforce the existing risk prediction models for better healthcare services.
AIMS OF THE STUDY: The compounds were quantified from 21 hydrolyzed extracts of the phytotherapies for gout. The activity-content contributions of the compounds to the potent extracts were determined.
MATERIALS AND METHODS: The anti-hyperuricemic activities of the extracts and the compounds were determined using a xanthine oxidase inhibitory assay. Ultra-Performance Liquid Chromatography (UPLC) coupled with Photodiode Array Detector (PDA) was used to quantify the compounds in the extracts.
RESULTS: The results revealed higher activity of the hydrolyzed extracts. The hydrolyzed extract of the flower bud of Syzygium aromaticum Merr. & L.M.Perry exhibited the highest activity (EC50 = 39.58 ± 0.10 μg/mL) due to the highest content of myricetin (42,297.55 ± 159.47 μg/g). The activity-content contribution of myricetin was 7.69%. Due to the highest activity of apigenin (EC50 = 3.27 ± 0.09 μg/mL), the highest contribution of this flavone (29.96%) to the hydrolyzed extract of Orthosiphon aristatus (Blume) Miq. was observed.
CONCLUSION: The results revealed different contents and activities of xanthine oxidase inhibitors in the hydrolyzed extracts of anti-hyperuricemic plants can play a major role to influence the activity.
METHODS: This was an open-label, prospective, case-controlled study, conducted over 12 months. Fifty-two consecutive patients referred for secondary hypertension were screened. Eighteen patients with confirmed PA (diagnosis based on the Endocrine Society clinical guideline) and seventeen matched controls with essential hypertension were recruited. BTM (CTX and P1NP), BMD, intact parathyroid hormone (iPTH), and bone profile were assessed at baseline and three months following treatment among the PA patients. Calcium intake was assessed using a validated questionnaire. Primary outcomes were the changes of bone markers and BMD following treatment of PA, and their relation to other parameters.
RESULTS: PA patients had significantly lower serum calcium and higher iPTH despite comparable vitamin D levels with control group. Both BTM were significantly higher among the PA group. BMD of lumbar spine, neck of femur and distal radius did not differ between groups. Three months following treatment, there were significant: 1) reduction in BTM; 2) improvement in the lumbar spine BMD; 3) reduction in iPTH level; and 4) increment of serum 25-OH vitamin D level.
CONCLUSIONS: Our findings support that bone loss and potential fracture risk among PA patients are likely a result of aldosterone-mediated secondary hyperparathyroidism. Patients with early PA may already exhibit increased bone turnover despite no significant changes in BMD.
METHODS: A retrospective study in a single center, all adult patients who were diagnosed with primary hyperaldosteronism and underwent AVS in our center between 2014 until 2022 were included. Successful samples defined by a selectivity index of ≥2, that is, the ratio of adrenal vein cortisol level to the peripheral vein cortisol level, were evaluated. The baseline demographic characteristics of each patient, technical parameters of AVS, and anatomical parameters of right adrenal vein from the venographic images were evaluated and analyzed to correlate with the outcome of AVS. A P-value of <0.05 was considered statistically significant.
RESULTS: The overall success rate of AVS in our center was 61.3%. The success rate significantly increased to 80.6% in the trained interventional radiologist (IR) group, which represents a single IR who had completed specific training in AVS, compared to non-trained IR group which consisted of a total of 10 IRs without specific AVS training (P = 0.046). The right AVS had lower success rate than the left AVS (64% vs. 94.6%). The type of right adrenal vein pattern showed significant association with the outcome of AVS (P = 0.014). There were 6 types of right adrenal vein patterns observed in our study; Type 1 - gland-like pattern with numerous branches, Type 2 - delta pattern, Type 3 - triangular pattern with central "blush", Type 4 - no discernible pattern and Type 5 - spidery or stellate pattern. The sixth pattern was the hepatic radicles blush with hepatic drainage, for which blood sampling were also collected due to its appearance was frequently indistinguishable from the Type 1 pattern. The results showed Type 2 pattern had the highest incidence (30.5%; 32/105 samples) and Type 5 had the highest success rate (100%; 11/11 samples), while the hepatic radicles blush pattern had the highest incidence in fail samples resulting in the highest failure rate (94.7%; 18/19 samples). The visualization of the inferior emissary vein (IEV) from the venographic images during right AVS had a significant association with the successful AVS (97.5% success rate; 39/40 samples; P = 0.003). Contrariwise, blood sampling withdrawn from the right adrenal vein in the presence of hepatic drainage communication associated with the failure AVS (86.7% failure rate; 26/30 samples; P = 0.001).
CONCLUSIONS: The overall success rate of both AVS in our center was 61.3%, and the success rate was higher in the trained IR group than the non-trained IR group. The visualization of IEV and the type of right adrenal vein patterns were the key determining factors with significant association to the successful right AVS. Conversely, blood sampling withdrawn from the hepatic radicles and hepatic drainage had significant association with the failure right AVS.
OBJECTIVE: The main objective is to develop an efficient cryopreservation technique for Aranda Broga Blue orchid PLBs using droplet-vitrification method.
MATERIALS AND METHODS: Several critical factors in cryopreservation were accessed such as preculture concentrations and durations, choice of vitrification solutions, two-step or three-step vitrification, growth recovery medium and PVS2 exposure duration.
RESULTS: The best growth regeneration percentage (5%) was obtained when 3-4mm PLBs were precultured in 0.2M sucrose for 3 days, followed by osmoprotection for 20 minutes, dehydration in PVS2 for 20 minutes at 0 degree C, LN storage, thawed and unloading for 20 minutes, and growth regeneration in VW10 medium. PLBs were found to be very sensitive to osmotic stress imposed by high molecular weight cryoprotectant such as sucrose and glycerol. Osmotic potential of growth recovery medium is one of the main factors that affect growth recovery in cryopreserved PLBs.
CONCLUSION: Current report showed possibilities in cryopreserving Aranda Broga Blue PLBs using droplet-vitrification technique. However, further improvement of growth recovery can be done by focussing on approaches that facilitate sufficient water removal from PLBs without causing severe osmotic injuries to the plant cells.
