METHODS: Twenty volumes of interests consisting of six anterior and fourteen posterior edentulous regions were obtained from human mandibular cadavers. A CBCT system with a resolution of 80 µm (3D Accuitomo 170, J. Morita, Kyoto, Japan) and a µCT system with a resolution of 35 µm (SkyScan 1173, Kontich, Belgium) were used to scan the mandibles. Three structural parameters namely, trabecular number (Tb.N), trabecular thickness (Tb.Th), and trabecular separation (Tb.Sp) were analysed using CTAn software (v 1.11, SkyScan, Kontich, Belgium). For each system, the measurements obtained from anterior and posterior regions were tested using independent sample t-test. Subsequently, all measurements between systems were tested using paired t-test.
RESULTS: In CBCT, all parameters of the anterior and posterior mandible showed no significant differences (p > 0.05). However, µCT showed a significant different of Tb.Th (p = 0.023) between anterior and posterior region. Regardless of regions, the measurements obtained using both imaging systems were significantly different (p ≤ 0.021) for Tb.Th and Tb.N.
CONCLUSIONS: The current study demonstrated that only the variation of Tb.Th between anterior and posterior edentulous region of mandible can be detected using µCT. In addition, CBCT is less feasible than µCT in assessing trabecular bone microstructures at both regions.
RESULTS: Genome-based taxonomic classification revealed the microbial richness present in the pristine Madison aquifer. The strains were found to span eleven genera and fourteen species, of which eight had uncertain taxonomic classifications. The genomes of strains SD129 and SD340 were found to contain the archetypical AHL QS system composed of two genes, luxI and luxR. Surprisingly, the genomes of strains SD115, SD129, SD274 and SD316 were found to contain one to three luxR orphans (solos). Strain SD129, besides possessing an archetypical AHL QS luxI-luxR pair, also contained two luxR solos, while strain SD316 contained three LuxR solos and no luxI-luxR pairs. The ligand-binding domain of two LuxR solos, one each from strains SD129 and SD316, were found to contain novel substitutions not previously reported, thus may represent two LuxR orphans that detection and response to unknown self-produced signal(s), or to signal(s) produced by other organisms.
AIM: This study examined the therapeutic effects of self-regulated learning on reducing challenging behaviors and enhancing school-related function in children with autism spectrum disorders.
METHODS: Forty children (aged 6-12) were randomized into a 12-week Self-Regulated Learning or Activity-Based intervention control group. Three outcome measures, assessing the behavior and school-related function of the children in both groups, were administered before and after the intervention and at one-month follow-up. The results between the two groups were also compared.
RESULTS: The Self-Regulated Learning group showed significantly better results in reducing concerning behaviors and enhancing the school-related function than the activity-based group post-intervention and at one-month follow-up.
CONCLUSIONS: The Self-Regulated Learning intervention was more effective compared to the Activity-Based intervention with particular benefits for on-going learning and improvements.
METHODS: The study applied mixed-method embedded design to analyze both quantitative and qualitative data. Quantitative approach was used to evaluate sustainability perception from 20 intervention clinics via self-reported assessment form whereas qualitative data were obtained through in-depth interview (IDI) and focus group discussions (FGDs) 14 health care professionals participated in IDI session and were either care coordinators, liaison officers (LOs)/clinic managers, or medical officers-in-charge for the clinic's intervention. Nine FGDs conducted comprised 58 HCPs from various categories.
RESULTS: HCPs from all the 20 clinics involved responded to each listed Enhanced Primary Healthcare (EnPHC) intervention components as being implemented but the perceived sustainability of these implementation varies between them. Quantitative feedback showed sustainable interventions included risk stratification, non-communicable disease (NCD) screening form, referral within clinics and hospitals, family health team (FHT), MTAC services and mechanisms and medical adherence status. Qualitative feedback highlighted implementation of each intervention components comes with its challenges, and most of it are related to inadequate resources and facilities in clinic. HCPs made initiatives to adapt based on clinical setting to implement the interventions at best level possible, whereby this seems to be one of the core values for sustainability.
CONCLUSION: Overall perceptions among HCPs on sustainability of EnPHC interventions are highly influenced by current experiences with existing resources. Components perceived to have inadequate resources are seen as a challenge to sustain. It's crucial for stakeholders to understand implications affecting implementation process if concerns raised are not addressed and allocation of needed resources to ensure overall successfulness and long term sustainability.
MATERIALS & METHODS: Standardised surgical technique with Parametrium & Paracolpium resection approach was adopted by qualified and experienced Gynecologic/Gyne-Oncologic Endoscopic & Minimally Invasive Surgeons in performing Laparoscopic Radical Hysterectomy for Cervical Cancer stage 1A1-1B1 from January 2009-May 2014, involving 53 patients. Electronic Medical Record system (EMR) Of Chang Gung Memorial Hospital(Tertiary Referral Centre), Department of Obstetrics & Gynecology was accessed for surgical and oncologic outcomes.
RESULTS: Fifty-Three patients operated from January 2009 to May 2014 were followed up for an average of 96.7 months with longest follow-up at 127 months. There were no cases of recurrence or death reported. 5 Year - Survival Rate and 5 Year Disease-Free Survival Rate were 100%. Two patients received post-operative pelvic radiation concurrent with chemotherapy using Cisplatin due to greater than 1/3 cervical stromal invasion.
CONCLUSION: It is vital to standardize minimally invasive surgical techniques for early stage cervical cancer, with focus on adequate radicality and resection which may contribute to excellent survival outcomes. Further international multi-center randomized trial (Minimally Invasive Therapy Versus Open Radical Hysterectomy In Cervical Cancer) will provide justification for continued practice of MIS in early stage cervical cancer.
MATERIALS AND METHODS: This is an observational cohort study and retrospective case assessment, involved twins born at Linkou Chang Gung Memorial Hospital, Taoyuan, Taiwan between 2013 and 2018. DC twins with selective IUGR (sIUGR) were defined as the presence of a birth weight discordance of >25% and a smaller twin with a birth weight below the tenth percentile. PDA was diagnosed using echocardiography between postnatal day 3 and 7. Hs-PDA was defined as PDA plus increased pulmonary circulation, poor systemic perfusion, cardiomegaly, pulmonary edema, or hypotension requiring pharmacotherapeutic intervention.
RESULT: A total of 1187 twins were delivered during the study period, and 53 DC twins with selective IUGR were included in this study. DC twins with PDA have higher rate of preterm birth, lower gestational age of delivery, and lower mean birth weight of both twins compared with DC twins without PDA. In a comparison of the sIUGR twin with the appropriate for gestational age co-twin, both the incidences of PDA (28.30% vs. 7.55%, respectively; P = 0.003) and Hs-PDA (24.53% vs. 5.66%, respectively; P = 0.002) were higher in sIUGR fetuses than in the appropriate for gestational age co-twins. Small gestational age of delivery was the only variable to predict PDA and Hs-PDA [p = 0.002, Odds ratio = 0.57 (0.39-0.82), p = 0.009, Odds ratio = 0.71 (0.55-0.92), respectively].
CONCLUSION: An analysis of dichorionic twins with sIUGR indicated that IUGR increased the risk of PDA and hemodynamically significant PDA.
Methods: One hundred and eighty standardized disc samples were prepared, of which ninety samples each were used for surface roughness and microhardness test, respectively. They were divided equally into: Group 1 (Filtek-Z350-XT), Group 2 (Zmack-Comp), and Group 3 (Zr-Hybrid). For surface roughness test, all samples were polished with aluminium oxide discs and further subdivided into aged and unaged subgroups, in which composite samples in aged subgroups were subjected to 2500 thermal cycles. Next, all the samples were subjected to surface roughness test using a contact stylus profilometer. As for microhardness test, all the aged and unaged samples were tested using a Vickers hardness machine with a load of 300 kgf for 10 s and viewed under a digital microscope to obtain microhardness value. Data were analyzed using two-way ANOVA followed by post hoc Tukey's honestly significant difference and paired sample t-test with significance level set at P = 0.05.
Results: In both the aged and unaged groups, Zr-Hybrid showed statistically significantly lower surface roughness (P < 0.05) than Filtek-Z350-XT and Zmack-Comp, but no statistically significant difference was noted between Filtek-Z350-XT and Zmack-Comp (P > 0.05). A similar pattern was noted in microhardness test, whereby Zr-Hybrid showed the highest value (P < 0.05) followed by Filtek-Z350-XT and lastly Zmack-Comp. Besides, significant differences in surface roughness and microhardness were noted between the aged and unaged groups.
Conclusion: Zr-Hybrid seems to demonstrate better surface roughness and microhardness value before and after artificial ageing.
