MATERIALS AND METHODS: This cross-over study incorporated 90 special needs children who were recruited to receive dental treatment with two ways of behavior guidance exposures consecutively in the order of A-B/B-A design. Exposure A is CBBGT (distraction, tell-show-do, and positive reinforcement), while Exposure B is PB. The dental procedures were either dental prophylaxis or restoration with a handpiece. Caregivers need to answer a paper-based questionnaire before and after exposure. The Wilcoxon sign rank test and logistic regression were utilized in order to establish the comparability, impacts, and association.
RESULT: About 88 caregivers of special needs children aged between 2 and 15 years completed the sequence. Overall, 98.9% of the children presented with neurodevelopmental disorders. Twenty-seven caregivers were significantly concerned when the combination of basic BGT was applied to their children, and 14 caregivers felt the same for PB. However, the Wilcoxon sign rank test revealed insignificant caregiver scores on acceptance and consent for both methods but significantly improved attitudes towards the use of PB after observing the placement of their children.
CONCLUSION: The studied caregiver demonstrated equivalent acceptance, consent, and concern toward the use of PB and a combination of basic BGT with improved attitudes after comprehensive explanation and real-time observation of PB usage during their children's dental treatment.
MATERIAL AND METHODS: This is a retrospective observational study done in Hospital Sg Buloh (HSB), a tertiary referral centre in an urban area located north of Kuala Lumpur, Malaysia's capital city, from January until December 2018, involving 289 patients. All cases with CPR and a sustained return of spontaneous circulation (ROSC) were included in the study and followed up until discharged or died in the hospital.
RESULTS: Out of 236 patients recruited, 25.8% achieved ROSC, 15.7% survived on admission, and 4.2% of patients were discharged alive. Of 74.1% of witnessed OHCA, only 17.5% received bystander CPR. Factors with favourable outcomes include CA in ED (p<0.001), the initial rhythm of ventricular fibrillation (p=0.003), defibrillation (p=0.024), OHCA witnessed by emergency medical services (EMS) (p=0.024) and intravenous adrenaline administration (p=0.001). When using multivariate regression analysis, positive outcomes were associated with the cardiac and respiratory cause of CA (Adjusted Odd Ratio (AOR) 3.66; 95% Confidence Intervals, 95%CI: 2.52 - 12.61 and AOR 8.76; 95%CI: 5.76- 15.46, respectively) as well as OHCA witnessed by EMS (AOR 10.81; 95%CI: 1.84- 19.52).
CONCLUSIONS: Despite being an upper-middle-income country and having advancements in the healthcare system, a relatively lower STD rate among survivors of CA in the ED was observed in this study. There was underutilization of the EMS among patients with CA. The bystander CPR rate among patients with CA in Malaysia is also worryingly low. Aggressive community participation in cardiac arrest awareness programmes is much required. Additionally, in achieving better outcomes, implementing standardized post-resuscitation care protocols with existing resources will be a challenge for physicians managing cardiac arrest cases.
METHODS: We employed a methodical bibliometric approach, making use of Scopus and Web of Science (WoS) databases for gathering literatures. We planned our search strategy, concentrating on terms linked to "breast imaging," "image quality," and "diagnostic accuracy" to ensure a systematic examination of the subject. The enhanced search functions in these databases enabled us to narrow down and improve our findings, choosing only the articles, conference papers, and book sections that are most relevant. After conducting a thorough screening process to remove duplicates and evaluate significance, we utilized ScientoPy and VOSviewer software for an in-depth bibliometric analysis. This helped to explore trends in publications, patterns of citations, and thematic groups, giving us a better understanding of how the field has changed and where it currently stands. Our approach prioritized assessing methodological quality and bias in the studies we included, guaranteeing the reliability of our findings.
RESULTS: We reviewed 2984 relevant publications, revealing a consistent annual growth rate of 2.8% in breast imaging research, with the United States and Europe leading in contributions. The study found that advancements in radiological technologies and international collaboration are driving forces behind the field's expansion. Key subject areas such as 'Radiology, Nuclear Medicine, and Medical Imaging' dominated, underscoring their impact on diagnostic quality. Notable authors and institutions have been identified for their influential research, characterized by high citation metrics and significant scholarly impact.
CONCLUSION: The study shows a continuous increase in research on breast imaging, considered by new technologies and teamwork defining the present time. The assessment highlights a key move towards utilizing digital imaging methods and computational analysis, affecting the improvement of future diagnostic procedures and patients' results. The study highlights the importance of continued international collaborations to tackle the new barriers in breast imaging and make the most of technological progress.
IMPLICATIONS FOR PRACTICE: This study shows a focus on using interdisciplinary methods and cutting-edge technology in breast imaging to help healthcare professionals improve their performance and accuracy in diagnosis. Recognizing vital research and emerging trends should guide clinical guidelines, radiology training, and patient care plans to encourage the use of effective techniques and stimulate innovation in diagnostic approaches.
OBJECTIVES: To assess the expression of DDR1 and DVL1 and their association with histological type, grading and hormonal status of IDC and ILC.
MATERIALS AND METHODS: This cross sectional study was conducted on IDC and ILC breast tumours. Tumours were immunohistochemically stained for (DDR1) and (DVL1) as well as estrogen receptor (ER), progesterone receptor (PR) and C-erbB2 receptor. Demographic data including age and ethnicity were obtained from patient records.
RESULTS: A total of 51 cases (30 IDCs and 21 ILCs) were assessed. DDR1 and DVL1 expression was not significantly associated with histological type (p=0.57 and p=0.66 respectively). There was no association between DDR1 and DVL1 expression and tumour grade (p=0.32 and p=1.00 respectively), ER (p=0.62 and 0.50 respectively), PR (p=0.38 and p=0.63 respectively) and C-erbB2 expression (p=0.19 and p=0.33 respectively) in IDC. There was no association between DDR1 and DVL1 expression and tumour grade (p=0.52 and p=0.33 respectively), ER (p=0.06 and p=0.76 respectively), PR (p=0.61 and p=0.43 respectively) and C-erbB2 expression (p=0.58 and p=0.76 respectively) in ILC.
CONCLUSIONS: This study revealed that DDR1 and DVL1 are present in both IDC and ILC regardless of the tumour differentiation. More studies are needed to assess the potential of these two proteins in distinguishing IDC from ILC in breast tumours.
Objectives: The current study aimed at determining the effects of degarelix on bone turnover, bone densitometry, and bone mechanical strength in male rats.
Methods: Eighteen male Sprague-Dawley rats were randomly divided into sham (SHAM), orchidectomized (ORX), and degarelix-induced (DGX) groups. Chemical castration was performed by subcutaneous degarelix injection (2 mg/kg) at the scapular region. The rats were scanned for baseline bone mineral area (BMA), bone mineral content (BMC), and bone mineral density (BMD) using dual-energy x-ray absorptiometry (DXA). Following six weeks of experimental period, BMA, BMC, and BMD were measured again with DXA and blood was collected for testosterone and bone biomarkers (osteocalcin and C-terminal of type I collagen crosslink (CTX-1)) measurements. The rats were euthanized and femora were dissected for bone biomechanical strength analysis.
Results: Bilateral orchidectomy and degarelix administration significantly lowered serum testosterone level, decreased whole body BMC, femoral BMA, femoral BMC, and femoral BMD (P < 0.05) compared with the SHAM group. However, no significant changes were observed in bone biochemical markers and bone mechanical strength in all experimental groups.
Conclusions: In conclusion, degarelix administration had comparable effects on bone as bilateral orchidectomy. Administration of degarelix provides an alternative method of inducing testosterone deficient-osteopenia in male rats without need for removing the testes.
MATERIALS AND METHODS: We retrospectively reviewed ultrasound and CT images for 146 patients with clinical suspicion of cholecystitis from January 2013 until December 2018. Ultrasound criteria reviewed included calculus, wall thickening, pericholecystic fluid, gallbladder distension and presence of echogenic material within the gallbladder. For CT, criteria reviewed were wall thickening, gallbladder distension, mucosal enhancement, pericholecystic fluid and hyperdense bile with an attenuation value of more than 20 HU. Association of these findings was made with intraoperative and pathological findings of 85 patients with proven gallbladder empyema.
RESULTS: Sonographic signs that were statistically significantly associated with gallbladder empyema (p < 0.05) were thickened gallbladder wall (mean 5.4 versus 3.0 mm), distended gallbladder (mean 8.5 versus 6.4cm), pericholecystic fluid and echogenic material within the gallbladder. No significant association between gallstones and gallbladder empyema. Scores of two and more out of four significant sonographic findings were found to have an association with higher chances of developing gallbladder empyema (p < 0.05, odds ratio: 10). None of the CT features was found to be significant with gallbladder empyema (p > 0.05).
CONCLUSION: A combination of few ultrasound features has a high significant association with gallbladder empyema. Thus, in the proper clinical setting, these findings should alarm the sonographic operator on the possibility of gallbladder empyema.
