ABSTRACT

OBJECTIVES: Boarding of adolescent patients with mental health concerns requiring ongoing observation and treatment is of increasing concern across US emergency departments. The objective was a proof of concept of developing an adolescent psychiatric emergency unit and assessment of the impact of this unit on lengths of stay (LOS).

METHODS: We describe the creation of the unit designed to allow safe assessment and boarding of patients, and appropriate interventions and services, while arranging transfer to inpatient facility or safe discharge home. Using a precreation and postcreation analysis and comparison with a similar facility that did not create such a unit, we utilized linear regression to investigate the primary outcome of total length of stay and secondary outcomes of psychiatric emergency department and pediatric emergency department length of stay for both unit-eligible patients and all patients.

RESULTS: The overall length of stay was not associated with a statistically significant change for unit-eligible patients; however, there was a significant decrease in the pediatric emergency department LOS for unit-eligible patients. This was associated with a decrease in beds lost to boarding in the pediatric emergency department of 544 hours per month.

CONCLUSIONS: Creation of an adolescent psychiatric emergency unit without allotment of significant additional resources is an option to decrease pediatric emergency department boarding times for adolescent patients requiring ongoing emergent therapy for mental health concerns.

ABSTRACT

This study uses fNIRS to determine whether there is a difference in the relationship between intra-individual variability and frontal lobe activity between ADHD patients and typically developing children. A total of 28 subjects (14 in ADHD patient group and 14 in control group) participated in this study. The subjects were tested for K-SADS and intelligence, and then the frontal lobe activity of the subjects was measured by continuous performance test, using functional near-infrared spectroscopy (NIRSIT). Processing speed index was significantly lower in the ADHD patient group than in the control group (p = .04). The CPT test results showed a positive correlation in the activity of the right dorsolateral prefrontal region in the patient group, but not at a statistically significant level. In the control group, activity showed a significant level of negative correlation with commission and hit reaction time standard deviation (p = .023; p = .063 respectively). In contrary to ADHD patient group, activation of the right dorsolateral prefrontal area was significantly correlated with reduction of intra-individual variability. This result showing that the relationship between activation of the right dorsolateral prefrontal area of the ADHD patient group and intra-individual variability shows a different pattern from typically developing children.

ABSTRACT

Allogeneic grafts can be preferred to autogenous grafts in plastic and oral-maxillofacial surgery for vertical and horizontal bone deficiencies. Implant surface properties are an important factor in osseointegration. This study aims to evaluate the osseointegration levels of titanium implants with machined, sand-blasted, and acid-etched (SLA) and resorbable blast material (RBM) surfaces placed together with allogeneic bone tissue transplantations obtained from the tibia bone using biomechanical method. Twenty-five female Sprague-Dawley rats were included in the study. The rats were divided into groups in which machined (n=7), SLA (n=7), and RBM (n=7) surface implants were placed with the transplantation of bone taken from the tibia. Four rats (both left and right tibias) were used as donors. Grafts and implants were surgically placed in the corticocancellous part of the metaphyseal area of the tibia bones of rats. At the end of the 4-week experimental setup, all rats were killed, and the implants and surrounding bone tissue were subjected to biomechanical reverse torque analysis (N/cm). Sand-blasted acid-etched surface implants were observed to have higher biomechanical osseointegration levels than RBM and machined surface implants (P<0.05). No statistical difference could be detected between the RBM and machined surface implants (P>0.05). On the basis of the limited results of this study, it can be concluded that the osseointegration levels of SLA surface implants placed with allogeneic bone transplantation may be better than those of machined and RBM surface implants.

ABSTRACT

BACKGROUND: When using biological variation (BV) data, BV estimates need to be robust and representative. High-endurance athletes represent a population under special physiological conditions, which could influence BV estimates. Our study aimed to estimate BV in athletes for metabolism and growth-related biomarkers involved in the Athlete Biological Passport (ABP), by 2 different statistical models.

METHODS: Thirty triathletes were sampled monthly for 11 months. The samples were analyzed for human growth hormone (hGH), insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein 3 (IGFBP-3), insulin, and N-terminal propeptide of type III procollagen (P-III-NP) by immunoassay. Bayesian and ANOVA methods were applied to estimate within-subject (CVI) and between-subject BV.

RESULTS: CVI estimates ranged from 7.8% for IGFBP-3 to 27.0% for insulin, when derived by the Bayesian method. The 2 models gave similar results, except for P-III-NP. Data were heterogeneously distributed for P-III-NP for the overall population and in females for IGF-1 and IGFBP-3. BV components were not estimated for hGH due to lack of steady state. The index of individuality was below 0.6 for all measurands, except for insulin.

CONCLUSIONS: In an athlete population, to apply a common CVI for insulin would be appropriate, but for IGF-1 and IGFBP-3 gender-specific estimates should be applied. P-III-NP data were heterogeneously distributed and using a mean CVI may not be representative for the population. The high degree of individuality for IGF-1, IGFBP-3, and P-III-NP makes them good candidates to be interpreted through reference change values and the ABP.

ABSTRACT

OBJECTIVE: To evaluate the safety and efficacy of the Oral Health System by Fresh Health Inc., used in conjunction with manual toothbrushing (Fresh + MTB) as compared to string floss and manual toothbrushing (floss + MTB) and manual toothbrushing (MTB) alone, as measured by clinical signs of gingivitis, plaque reduction, pocket depth, and bleeding.

METHODS: One hundred ninety-two (192) generally healthy adults exhibiting signs of gingivitis completed this 30-day randomized, controlled, examiner-blinded, three-group parallel study design. All subjects were assigned a manual toothbrush and fluoride dentifrice, instructed to brush twice daily according to their normal habits, and provided with written and verbal instructions for all assigned products. Subjects in the control group used only the manual toothbrush and dentifrice. Subjects assigned to the string floss + MTB group were instructed to also floss once daily. Subjects assigned to the Fresh + MTB group were provided a Fresh Health Inc. custom-fit oral irrigator and instructed to use the device once daily with water for approximately 7 seconds in addition to toothbrushing. Gingivitis was assessed using the modified gingival index (MGI), bleeding on marginal probing was assessed via the gingival bleeding index (GBI), and plaque was measured using the Rustogi modified navy plaque index (RMNPI) at day 1, day 15, and day 30. Periodontal probing depth (PPD) and bleeding on probing (BOP) were measured at day 1 and day 30. Oral soft- and hard-tissue assessments were performed at all examination visits.

RESULTS: There was no significant difference in age or sex between groups, and no significant difference in baseline MGI, GBI, RMNPI, BOP, and PPD values across groups. The Fresh + MTB group demonstrated statistically significantly better performance than the floss + MTB group and MTB group across all clinical indices at both 15 days and 30 days. At 30 days, the Fresh + MTB group showed a 40.9% improvement in whole-mouth MGI, which was significantly greater than the MTB and floss + MTB groups.

ABSTRACT

The objective of this study was to evaluate the effect of different interdental oral cleaning modalities on gingivitis and plaque following a 6-week period of home use. This was a randomized, four-arm, parallel design clinical trial. Study subjects were manual toothbrush (MTB) users with moderate to severe gingivitis, aged 18 to 65 years. Subjects were required at baseline to have a gingival bleeding score of ≥1 on at least 50 gingival sites per the Gingival Bleeding Index (GBI) and to have an overall plaque score of ≥0.6 per the Rustogi Modified Navy Plaque Index (RMNPI) following a 3- to 6-hour plaque accumulation period. Subjects were randomly assigned to use one of four oral care cleaning modalities: (1) NON group: MTB alone, (2) FLS group: MTB plus string floss, (3) IDB group: MTB plus an interdental brush, or (4) CPF group: MTB plus the Philips® Sonicare® Cordless Power Flosser with the Quad Stream nozzle. Efficacy measures (Modified Gingival Index [MGI], GBI, and RMNPI) and safety were assessed at baseline, 2 weeks, and 6 weeks. The primary efficacy endpoint was the reduction in gingival inflammation from baseline to week 6 as measured by the MGI. Of the 372 subjects randomized in the study, 364 completed a post-baseline MGI evaluation and were included in the analyses. The adjusted mean percent reduction in gingival inflammation from baseline to week 6 was -2.10% for the NON group, 2.82% for the FLS group, 2.60% for the IDB group, and 29.10% for the CPF group. Pairwise comparisons indicated that the CPF group was statistically significantly different from the NON, FLS, and IDB groups (.0001). In conclusion, adjunctive use of the Philips Sonicare Cordless Power Flosser with the Quad Stream nozzle and an MTB showed statistically better results in term of reducing gingival inflammation following 6 weeks of home use when compared to an MTB alone, an MTB used with string floss, and an MTB used with an interdental brush.

ABSTRACT

The study objective was to evaluate the effect of two different interdental oral cleaning modalities on gingivitis and plaque following a 4-week period of home use. This was a randomized, parallel, single-blinded study. Subjects were routine manual toothbrush (MTB) users with moderate to severe gingivitis, aged 18 to 65 years. Subjects were required at baseline to have a gingival bleeding score of ≥1 on at least 50 gingival sites per the Gingival Bleeding Index (GBI) and to have an overall plaque score of ≥0.6 per the Rustogi Modified Navy Plaque Index (RMNPI) following a 3- to 6-hour plaque accumulation period. Subjects were randomly assigned to one of three groups based on the oral care cleaning modalities: (1) NON group: MTB alone, (2) IDB group: MTB plus an interdental brush, or (3) MPF group: MTB plus a Philips® Sonicare® Power Flosser with the Quad Stream nozzle. All subjects used the MTB with fluoride toothpaste. Efficacy measures (Modified Gingival Index [MGI], GBI, and RMNPI) and safety were assessed at baseline, 2 weeks, and 4 weeks. The primary efficacy endpoint was the reduction in gingival inflammation from baseline to week 4 as measured by the MGI. A total of 189 subjects were randomized and 186 completed the study. The adjusted mean percent reduction in gingival inflammation from baseline to week 4 was 2.80% for the NON group, 11.32% for the IDB group, and 20.87% for the MPF group. The differences between the MPF group and the NON and IDB groups were statistically significant (.0001). In conclusion, use of the MTB with the Philips Sonicare Power Flosser showed statistically significant benefits compared to an MTB alone and an MTB used with an interdental brush in reducing gingival inflammation following 4 weeks of home use.

Safety and efficacy measures (Modified Gingival Index [MGI], GBI, and RMNPI) were assessed at baseline, 2 weeks, and 6 weeks. The primary efficacy endpoint was the reduction in gingival inflammation from baseline to week 6 as measured by the MGI. A total of 260 subjects were randomized and 256 subjects completed the study. The adjusted mean percent reduction in gingival inflammation from baseline to week 6 was 14.90% for the NON group, 13.16% for the FLS group, 33.51% for the MPF group, and 49.30% for the PPF group. Pairwise comparisons indicated that both the PPF and MPF groups were statistically significantly different from both the NON and FLS groups. In conclusion, use of either the Philips Sonicare power toothbrush with the Philips Sonicare Power Flosser or an MTB with the Philips Sonicare Power Flosser was statistically superior to an MTB alone and an MTB used with string floss in reducing gingival inflammation following 6 weeks of home use.

ABSTRACT

OBJECTIVE: To examine the newly established role of a primary contact physiotherapist in an ENT clinic, in an Australian cohort and context, over two phases of development.

METHODS: A retrospective cohort study was conducted with data collected from a medical record audit. Over the study duration, the primary contact physiotherapist completed initial appointments with patients; follow-up appointments were subsequently conducted by medical staff.

RESULTS: There was a 46 per cent reduction in patients with suggested vestibulopathy requiring an ENT medical review. This reduction could hypothetically increase to 71 per cent with follow-up primary contact physiotherapist appointments. Improvements in the service delivery model and a primary contact physiotherapist arranging diagnostic assessments could improve waitlist times and facilitate better utilisation of medical staff time.

CONCLUSION: The primary contact physiotherapist can help in the management of patients with suspected vestibulopathy on an ENT waitlist. This is achieved through: a reduction of patients requiring ENT review, improvements to waitlist time and improved utilisation of medical specialists’ time.
