This study retrospectively analyzed the effect of clinical factors on the outcomes of REP(regenerative endodontic procedure). Patients who received the REP using triple antibiotic paste due to trauma or fracture of dens evaginatus from February, 2011 to January, 2020 were included in the study. Finally, 57 teeth in 54 patients were selected. Investigated clinical factors were as follows: intentional bleeding, etiology, and root development stage. Treatment outcomes evaluated were as follows: improvement of subjective symptoms, changes in the periapical lesion, and the amounts of root development after REP. To compensate for differences in angulation and position between repeated radiographic examinations, images were aligned by Turboreg plugin. To evaluate the amounts of root development, apical diameter, root area, and root length were measured by ImageJ software. Among the aforementioned factors, intentional bleeding had no significant effect on treatment results. Regarding the etiology, the increase in the root area and the root length was significantly less in trauma cases than in dens evaginatus fracture cases. Considering root development stage, more immature teeth presented more increase in the root area.

AbstractThe presence of postoperative complications may have a significant impact on the outcome of the breast reconstruction. The aim of this study was to investigate early postoperative complications and the risk factors for their occurrence. A prospective analysis was carried out to evaluate surgical outcomes after breast reconstructive surgeries performed over a 2-year period. Procedures included expander/implant (TE/IMP), pedicle transverse rectus abdominis musculocutaneous (pTRAM), and latissimus dorsi (LD) techniques. All adverse events which occurred within 6 weeks of surgery were ranked according to severity based on the contracted Accordion grading system. Outcomes were assessed for their association with surgical, demographic, and clinical variables. Sixty-one consecutive breast reconstruction procedures were analyzed. The overall complication rate was 60.7% (n = 37), and 8 patients (13.1%) required reoperation. The lowest complication rate was observed in implant-based reconstructions (TE/IMP, 18.8%; pTRAM, 72.7%; LD, 78.3%; p = 0.008). Mild complications occurred significantly more often after LD reconstructions (LD, 60.9%; pTRAM, 22.7%; TE/IMP, 12.5%; p = 0.031), while severe complications were significantly more frequent after the pTRAM procedures (pTRAM, 27.3%; TE/IMP, 6.2%; LD, 8.7%; p = 0.047). Severe complications were associated with higher rehospitalization rate (p = 0.010) and longer hospital stay. Study revealed a significant impact of the operative method on the incidence and severity of early complications after breast reconstruction procedures with little effect from other demographic and clinical factors.

Objective The aim of the study is to investigate factors affecting total sleep time (TST) during infant polysomnography (PSG) and assess if <4 hours of TST is sufficient for accurate interpretation. Study Design Overall, 242 PSGs performed in 194 infants <6 months of chronological age between March 2013 and December 2015 were reviewed to identify factors that affect TST, including age of infant, location and timing of study, presence of medical complexity, and presence of nasal tubes. A continuum of apnea-hypopnea index (AHI) in relation to TST was reviewed. Data were examined in infants who had TST <4 hours and low AHI. Results Greater TST (p < 0.001) was noted among infants during nocturnal PSGs, at older chronological and post-menstrual ages, and without medical complexity. The presence of nasogastric/impedance probes reduced TST (p = 0.002). Elevated AHIs were identified even in PSGs with TST <4 hours. Short TST may have affected interpretation and delayed initial management in one infant without any inadvertent complications. Conclusion Clinical factors such as PMA and medical complexity, and potentially modifiable factors such as time of day and location of study appeared to affect TST during infant PSGs. TST < 4 hours can be sufficient to identify high AHI allowing physician interpretation. Key Points

Stimulation Of

Tissue engineering is a growing field. In the near future, it will probably be possible to generate a complete vital tooth from a single stem cell. Pulp revascularization is dependent on the ability of residual pulp and apical and periodontal stem cells to differentiate. These cells have the ability to generate a highly vascularized and a conjunctive rich living tissue. This one is able to colonize the available pulp space. Revascularization is a new treatment method for immature necrotic permanent teeth. Up to now, apexification procedures were applied for these teeth, using calcium dihydroxide or MTA to produce an artificial apical barrier. However, the pulp revascularization allows the stimulation of the apical development and the root maturation of immature teeth. Two pulp revascularization techniques are used in the literature, one using calcium dihydroxide and the second using a triple antibiotic paste. Based on these two different pulp revascularization protocols, which obtain the desired therapeutic success, the literature will be reviewed and analyzed according to the relevance of their choice of materials. Based on the literature, we propose a new relevant protocol and a new mixture of antibiotics.

Selection Of

Selection of common bean (Phaseolus vulgaris L.) cultivars with enhanced root growth would be a strategy for increasing P uptake and grain yield in tropical soils, but the strong plasticity of root traits may compromise their inclusion in breeding programs. The aim of this study was to evaluate the magnitude of the genotypic variability of root traits in common bean plants at two ontogenetic stages and two soil P levels. Twenty-four common bean genotypes, comprising the four growth habits that exist in the species and two wild genotypes, were grown in 4 kg pots at two levels of applied P (20 and 80 mg kg-1) and harvested at the stages of pod setting and early pod filling. Root area and root length were measured by digital image analysis. Significant genotype × P level and genotype × harvest interactions in analysis of variance indicate that the genotypic variation of root traits depended on soil nutrient availability and the stage at which evaluation was made. Genotypes differed for taproot mass, basal and lateral root mass, root area and root length at both P levels and growth stages; differences in specific root area and length were small. Genotypes with growth habits II (upright indeterminate) and III (prostrate indeterminate) showed better adaptation to limited P supply than genotypes of groups I (determinate) and IV (indeterminate climbing). Between the two harvests, genotypes of groups II and III increased the mass of basal and lateral roots by 40 and 50 %, respectively, whereas genotypes of groups I and IV by only 7 and 19 %. Values of the genotypic coefficient of determination, which estimates the proportion of phenotypic variance resulting from genetic effects, were higher at early pod filling than at pod setting. Correlations between shoot mass and root mass, which could indicate indirect selection of root systems via aboveground biomass, were higher at early pod filling than at pod setting. The results indicate that selection for root traits in common bean genotypes should preferentially be performed at the early pod-filling stage.

ABSTRACT:A retrospective study of 100 patients with spontaneous intracerebral haemorrhage was carried out, to identify clinical factors which have a predictive value for outcome. Numerical equivalents for the admission level of consciousness (the Glasgow Coma Scale), ventricular rupture, partial pressure of oxygen in the blood, the electrocardiogram, clot location, and clot size were combined into equations predicting outcome. The best single parameter for prediction was the Glasgow Coma Scale.

Abstract Purpose To determine factors that influence insurance approval for definitive proton therapy (PT) for prostate cancer. Materials and Methods Between 2014 and 2018, 1592 insured patients with localized prostate cancer were evaluated and recommended to undergo definitive PT; 547 patients (34.4%) had commercial insurance, whereas 1045 patients (65.6%) had Medicare/Medicaid. Of those with Medicare, 164 patients (15.7%) had Medicare alone; 677 (64.8%) had supplemental plans; and 204 (19.5%) had secondary commercial insurance. Insurance that “covered” PT for prostate cancer implied that it was an indication designated in the coverage policy. “Not covered” means that the insurance policy did not list prostate cancer as an indication for PT. Of all 1592 patients, 1263 (79.3%) belonged to plans that covered PT per policy. However, approval for PT was still required via medical review for 619 patients (38.9%), comparative dosimetry for 56 patients (3.5%), peer-to-peer discussion for 234 patients (14.7%), and administrative law judge hearings for 3 patients (&lt;0.1%). Multivariate analyses of factors affecting approval were conducted, including risk group (low/intermediate versus high), insurance type (commercial versus Medicare/Medicaid), whether PT was included as a covered benefit under the plan (covered versus not covered), and time period (2014-16 versus 2017 versus 2018). Results On multivariate analysis, factors affecting PT approval for prostate treatment included coverage of PT per policy (97.1% had approval with insurance that covered PT versus 48.6% whose insurance did not cover PT; P &lt; .001); insurance type (32.5% had approval with commercial insurance versus 97.4% with Medicare; P &lt; .001); and time, with 877/987 patients (88.9%) approved between 2014 and 2016, 255/312 patients (81.7%) approved during 2017, and 255/293 patients (87.0%) approved thereafter (P = .02). Clinical factors, including risk group, had no bearing on insurance approval (P = .44). Conclusion Proton insurance approval for prostate cancer has decreased, is most influenced by the type of insurance a patient belongs to, and is unrelated to clinical factors (risk group) in this study. More work is needed to help navigate appropriate access to care and to assist patients seeking definitive PT for prostate cancer treatment.
