RESUMO
BACKGROUND: Intraoperative handoffs have been implicated as a contributing factor in many perioperative adverse events. Despite conflicting data around their impact on perioperative outcomes, they remain a vulnerable point in the perioperative system with significant attention focused on improving them. This study aimed to understand the processes in place surrounding the point of information transfer in intraoperative handoffs. METHODS: We used semistructured interviews with anesthesia clinicians to understand the processes and systems surrounding intraoperative handoffs. Interview data were coded deductively using the Systems Engineering Initiative for Patient Safety model as a framework, with subthemes developed inductively. RESULTS: Clinicians do a significant amount of work before and after the point of information transfer to ensure a smooth handoff and safe patient care. Despite not having standardization of handoffs, most clinicians have a typical handoff organization and largely agree on content that should be included. However, there is variability based on clinician and patient characteristics, including clinician discipline and patient acuity. These handoffs are additionally impacted by the overall culture in the operating room, including the teamwork and hierarchies present among the surgical and anesthesia teams. Finally, the broader operating room logistics, including scheduling practices for surgical cases and anesthesia teams, impact the quality of intraoperative handoffs and the ability of clinicians to prepare for these handoffs. CONCLUSIONS: Handoffs involve processes beyond the point of information transfer and are embedded in the systems and culture of the operating rooms. These considerations are important when seeking to improve the quality of intraoperative handoffs.
RESUMO
Managing a safe and efficient anaesthetic induction within a team involves the challenge of when, if, and how to surface, discuss, and implement the best plan on how to proceed. The Lemke and colleagues study in this issue of the British Journal of Anaesthesia is a unique view into real-world conversations that naturally occur in anaesthesia teams in moments of high task and cognitive load, such as induction of anaesthesia. The study spotlights important small moments of physician, nurse, and trainee team coordination. It illuminates key patterns of conversation in naturally occurring anaesthesia teams, and raises important questions about what the speaking up standard should be and the psychological safety-shaping role consultants play in setting the norms for speaking up.

OBJECTIVE: The objective of this study is to investigate the effectiveness of motivational interviewing (MI) in changing health behaviors (snack and toothbrushing) and preventing dental caries among adolescents. METHODS: Five hundred and twelve adolescents with unfavorable caries-related behaviors ("snacking three times or more a day" and/or "toothbrushing less often than twice a day") were randomly assigned to three groups. Group I received prevailing health education (oral health talks and pamphlets). Participants in group II joined a one-on-one face-to-face MI session. In group III, a patient communication tool (Cariogram) was incorporated to facilitate the MI process. At baseline and 24 months post-intervention, a self-administered questionnaire gathered information of participants' sociodemographic characteristics and oral health self-efficacy and behaviors. Their oral hygiene and tooth status were assessed by a blinded examiner. RESULTS: After 24 months, 460 (89.8%) participants were followed up. Compared with group I, (i) restriction of frequent snacking was more likely in group II [OR (95% CI): 3.91 (1.48-10.33)] and group III [OR (95% CI): 6.33 (2.46-16.27)], whereas group III tended to adopt the behavior of toothbrushing twice a day [OR (95% CI): 4.80 (1.79-12.85)]; (ii) no significant between-group difference in plaque score reduction was found (p > 0.05); and (iii) groups II and III developed fewer cavitated teeth (â³DICDASII 3-6MFT) [ß (95% CI): - 0.19 (- 0.37, - 0.01) and - 0.20 (- 0.38, - 0.02), respectively], whereas increment of total carious lesions (â³DICDASII 1-6MFT) was lower in group III [ß (95% CI): - 0.63 (- 1.24, - 0.02)]. CONCLUSION: MI outperformed prevailing health education in improving oral health behaviors and preventing dental caries among adolescents. CLINICAL RELEVANCE: Incorporating MI into dental care for caries-prone adolescents contributes to optimal health outcomes.

OBJECTIVES: The aim of the present superiority study was to determine the effect of systemic antibiotics primarily on patient-reported outcome measures (PROMs) and post-surgical complications in patients undergoing oral implant therapy with simultaneous guided bone regeneration (GBR). MATERIALS AND METHODS: A total of 236 medically and periodontally healthy patients received oral implants with simultaneous GBR at seven centres. Pre-operative antibiotics of 2 g amoxicillin were prescribed to the test group 1 hr prior to surgery and 500 mg thrice daily on days 1-3 after surgery. The control group was given a placebo. Group allocation was performed randomly. Primary outcome variables were PROMs recorded as visual analogue scale scores assessed on days 1-7 and 14 on pain, swelling, haematoma and bleeding. Post-operative complications as secondary outcome variables were examined at 1, 2, 4 and 12 weeks from surgery. Chi-square tests and repeated measures of analysis of variance (ANOVA) were performed for statistical evaluation. RESULTS: No statistically significant differences (p > .05) between the two groups were detected for the evaluated PROMs. The same was noted with respect to post-surgical complications. Four implants were lost-three in the test group and one in the control group. CONCLUSION: In this trial, systemic antibiotics did not provide additional benefits to PROMs, nor the prevention of post-surgical complications in medically and periodontally healthy patients undergoing oral implant therapy with simultaneous GBR. However, further studies with larger sample sizes are still required to support the clinical outcomes of this study.

BACKGROUND: Longitudinal invariance is a perquisite for a valid comparison of oral health-related quality of life (OHRQoL) scores over time. Item response theory (IRT) models can assess measurement invariance and allow better estimation of the associations between predictors and latent construct. By extending IRT models, this study aimed to investigate the longitudinal invariance of the two 8-item short forms of the Child Perception Questionnaire (CPQ11-14) regression short form (RSF:8) and item-impact short form (ISF:8) and identify factors associated with adolescents' OHRQoL and its change. METHODS: All students from S1 and S2 (equivalent to US grades 6 and 7) who were born in April 1997 and May 1997 (at age 12) from 45 randomly selected secondary schools were invited to participate in this study and followed up after 3 years. Data on the CPQ11-14 RSF:8 and CPQ11-14 ISF:8, demographics, oral health behavior and status were collected. Explanatory graded response models were fitted to both short forms of the CPQ11-14 data for assessing longitudinal invariance and factors associated with OHRQoL. The Bayesian estimation method - Monte Carlo Markov Chain (MCMC) with Gibbs sampling was adopted for parameter estimation and the credible intervals were used for inference. RESULTS: Data from 649 children at age 12 at baseline and 415 children at age 15 at follow up were analyzed. For the 12 years old children, healthier oral health behavior, better gum status, families with both parents employed and parents' education level were found to be associated with better OHRQoL. Four items among the 2 short forms lacked longitudinal invariance. With statistical adjustment of longitudinal invariance, OHRQoL were found improved in general over the 3 years but no predictor was associated with OHRQoL in follow-up. For those with decreased family income, their OHRQoL had worsened over 3 years. CONCLUSIONS: IRT explanatory analysis enables a more valid identification of the factors associated with OHRQoL and its changes over time. It provides important information to oral healthcare researchers and policymakers.

PURPOSE OF REVIEW: Simulation training in obstetric anesthesia has become widespread in recent years. Simulations are used to train staff and trainees, assess and improve team performance, and evaluate the work environment. This review summarizes current research in these categories. RECENT FINDINGS: Simulation to improve individual technical skills has focused on induction of general anesthesia for emergent cesarean delivery, an infrequently encountered scenario by anesthesia trainees. Low- and high-fidelity simulation devices for the learning and practicing neuraxial and non-neuraxial procedures have been described, and both are equally effective. The use of checklists in obstetric emergencies has become common as and post-scenario debriefing techniques have improved. Although participant task performance improves, whether participants retain learned skills or whether simulation improves patient outcomes has not yet been established. Tools to assess teamwork during simulation have been developed, but none have been rigorously validated. In-situ vs. offsite simulations do not differ in effectiveness. SUMMARY: Simulation allows for practice of tasks and teamwork in a controlled manner. There is little data whether simulation improves patient outcomes and metrics to predict the long-term retention of skills by simulation participants have not been developed.

BACKGROUND: Four-factor structure of the two 8-item short forms of Child Perceptions Questionnaire CPQ11-14 (RSF:8 and ISF:8) has been confirmed. However, the sum scores are typically reported in practice as a proxy of Oral health-related Quality of Life (OHRQoL), which implied a unidimensional structure. This study first assessed the unidimensionality of 8-item short forms of CPQ11-14. Item response theory (IRT) was employed to offer an alternative and complementary approach of validation and to overcome the limitations of classical test theory assumptions. METHODS: A random sample of 649 12-year-old school children in Hong Kong was analyzed. Unidimensionality of the scale was tested by confirmatory factor analysis (CFA), principle component analysis (PCA) and local dependency (LD) statistic. Graded response model was fitted to the data. Contribution of each item to the scale was assessed by item information function (IIF). Reliability of the scale was assessed by test information function (TIF). Differential item functioning (DIF) across gender was identified by Wald test and expected score functions. RESULTS: Both CPQ11-14 RSF:8 and ISF:8 did not deviate much from the unidimensionality assumption. Results from CFA indicated acceptable fit of the one-factor model. PCA indicated that the first principle component explained >30 % of the total variation with high factor loadings for both RSF:8 and ISF:8. Almost all LD statistic <10 indicated the absence of local dependency. Flat and low IIFs were observed in the oral symptoms items suggesting little contribution of information to the scale and item removal caused little practical impact. Comparing the TIFs, RSF:8 showed slightly better information than ISF:8. In addition to oral symptoms items, the item "Concerned with what other people think" demonstrated a uniform DIF (p < 0.001). The expected score functions were not much different between boys and girls. CONCLUSIONS: Items related to oral symptoms were not informative to OHRQoL and deletion of these items is suggested. The impact of DIF across gender on the overall score was minimal. CPQ11-14 RSF:8 performed slightly better than ISF:8 in measurement precision. The 6-item short forms suggested by IRT validation should be further investigated to ensure their robustness, responsiveness and discriminative performance.

In this study, we aimed to continuously measure cardiac output (CO) with the electrical velocimetry (EV) method and characterize the hemodynamic profile of patients undergoing spinal anesthesia for elective cesarean delivery (CD), and to discuss the potential benefit of using real time CO monitoring to guide patient management. Forty-two patients scheduled for elective CD under spinal anesthesia were enrolled in this observational study. A non-invasive CO monitor incorporating the electrical velocimetry algorithm, ICON(®) (Cardiotronic(®), La Jolla, California, USA), was used to measure CO and stroke volume (SV) continuously. Peripheral venous pressure was measured intermittently at pre-defined time points. Systemic vascular resistance was calculated retrospectively after completion of the study. Hemodynamic changes at pre-defined time points and caused by phenylephrine administration were analyzed. Hypotension (MAP reduction more than 20% from baseline values) occurred in 71.1% of patients after spinal anesthesia, while the coinstantaneous CO was increased ≥20% from baseline in the majority of patients (76.3%) at the same time. Significant increase in CO took place at 3-2 min before the administration of phenylephrine bolus. Treatment of hypotension with phenylephrine was associated with significant decrease in CO. Continuous CO monitoring with EV enables clinicians to determine CO and SV changes prior to onset of hypotension and to better understand patients' hemodynamics. It is an important addition to the current monitoring. The benefit of routinely using this technique remains to be determined in term of the patient outcomes.

BACKGROUND: Although feedback conversations are an essential component of learning, three challenges make them difficult: the fear that direct task feedback will harm the relationship with the learner, overcoming faculty cognitive biases that interfere with their eliciting the frames that drive trainees' performances, and time pressure. Decades of research on developmental conversations suggest solutions to these challenges: hold generous inferences about learners, subject one's own thinking to test by making it public, and inquire directly about learners' cognitive frames. METHODS: The authors conducted a randomized, controlled trial to determine whether a 1-h educational intervention for anesthesia faculty improved feedback quality in a simulated case. The primary outcome was an analysis of the feedback conversation between faculty and a simulated resident (actor) by using averages of six elements of a Behaviorally Anchored Rating Scale and an objective structured assessment of feedback. Seventy-one Harvard faculty anesthesiologists from five academic hospitals participated. RESULTS: The intervention group scored higher when averaging all ratings. Scores for individual elements showed that the intervention group performed better in maintaining a psychologically safe environment (4.3 ± 1.21 vs. 3.8 ± 1.16; P = 0.001), identifying and exploring performance gaps (4.1 ± 1.38 vs. 3.7 ± 1.34; P = 0.048), and they more frequently emphasized the professionalism error of failing to call for help over the clinical topic of anaphylaxis (66 vs. 41%; P = 0.008). CONCLUSIONS: Quality of faculty feedback to a simulated resident was improved in the interventional group in a number of areas after a 1-h educational intervention, and this short intervention allowed a group of faculty to overcome enough discomfort in addressing a professionalism lapse to discuss it directly.

BACKGROUND: High-quality teamwork among operating room (OR) professionals is a key to efficient and safe practice. Quantification of teamwork facilitates feedback, assessment, and improvement. Several valid and reliable instruments are available for assessing separate OR disciplines and teams. We sought to determine the most feasible approach for routine documentation of teamwork in in-situ OR simulations. We compared rater agreement, hypothetical training costs, and feasibility ratings from five clinicians and two nonclinicians with instruments for assessment of separate OR groups and teams. MATERIALS AND METHODS: Five teams of anesthesia or surgery residents and OR nurses (RN) or surgical technicians were videotaped in simulations of an epigastric hernia repair where the patient develops malignant hyperthermia. Two anesthesiologists, one OR clinical RN specialist, one educational psychologist, one simulation specialist, and one general surgeon discussed and then independently completed Anesthesiologists' Non-Technical Skills, Non-Technical Skills for Surgeons, Scrub Practitioners' List of Intraoperative Non-Technical Skills, and Observational Teamwork Assessment for Surgery forms to rate nontechnical performance of anesthesiologists, surgeons, nurses, technicians, and the whole team. RESULTS: Intraclass correlations of agreement ranged from 0.17-0.85. Clinicians' agreements were not different from nonclinicians'. Published rater training was 4 h for Anesthesiologists' Non-Technical Skills and Scrub Practitioners' List of Intraoperative Non-Technical Skills, 2.5 h for Non-Technical Skills for Surgeons, and 15.5 h for Observational Teamwork Assessment for Surgery. Estimated costs to train one rater to use all instruments ranged from $442 for a simulation specialist to $6006 for a general surgeon. CONCLUSIONS: Additional training is needed to achieve higher levels of agreement; however, costs may be prohibitive. The most cost-effective model for real-time OR teamwork assessment may be to use a simulation technician combined with one clinical rater to allow complete documentation of all participants.

OBJECTIVES: To determine the effect of various systemic antibiotic prophylaxis regimes on patient-reported outcomes and postsurgical complications in patients undergoing conventional implant installation. MATERIAL AND METHODS: Three hundred and twenty-nine healthy adults in need of conventional implant installation were randomly assigned to one of four groups: (i) preoperatively 2 g of amoxycillin 1 h before surgery (positive control, PC), (ii) postoperatively 2 g of amoxycillin immediately following surgery (test 1, T1), (iii) preoperatively 2 g of amoxycillin 1 h before and 500 mg thrice daily on days 2 and 3 after surgery (test 2, T2), (iv) preoperatively 2 g of placebo 1 h before surgery (negative control, NC). Subjects were examined clinically by blinded examiners over 8 weeks after implant installation. In addition, Visual Analogue Scales (VAS) for pain, swelling, bruising and bleeding were obtained over 14 days. ANOVA was performed for the VAS. Chi-square tests were applied for postsurgical complications. RESULTS: All VAS scores were low for all groups and decreased over time (P < 0.001). There were no significant differences for the VAS scores between the various groups at any time point (P > 0.05). There was only a significant difference in flap closure at week 4, where NC had 5% of the subjects not achieving complete wound closure compared to 0% for the three other groups (P = 0.01), with no other significant differences for any postsurgical complications (P > 0.05). CONCLUSION: For standard single implant placement, prophylactic systemic antibiotics either before or after, or before and after the surgical procedure do not improve patient-reported outcomes or prevalence of postsurgical complications.

BACKGROUND: Chronic orofacial pain (OFP) is common in general adult populations worldwide. High levels of psychological distress and impaired coping abilities are common among Western people with chronic OFP but limited information was found in southern Chinese people. This study aimed to explore the perceptions and experiences of community dwelling elderly people with chronic OFP symptoms and their treatment seeking behaviour in Hong Kong. METHODS: An exploratory qualitative interview study was conducted. Elderly people experiencing chronic OFP symptoms were invited to take part in an individual semi-structured interview. A total of 25 semi-structured interviews were performed for 25 participants. RESULTS: Pertinent issues relating to the treatment seeking behaviour emerged from the interviews, many of which were inter-related and overlapping. They were organized into three major themes: (i) Impact of chronic OFP on daily life; (ii) Personal knowledge and feeling of chronic OFP; (iii) Management of chronic OFP. The participants were found to have the intention to seek professional treatment, but there were barriers which discouraged them continuing to seek professional treatment. They also received complementary treatment for chronic OFP, such as acupuncture, massage and "chi kung". Moreover, a wide range self-management techniques were also mentioned. On the other hand, those who did not seek professional treatment for the chronic OFP claimed that they had accepted or adapted to the pain as part of their lives. CONCLUSIONS: This qualitative study observed that elderly people affected by chronic OFP symptoms in Hong Kong sought many different ways to manage their pain including traditional and complementary approaches. The role of the dentist in dealing with chronic OFP is unclear. Multiple barriers exist to accessing care for chronic OFP. The findings may be used to inform future chronic OFP management strategies in Hong Kong.

BACKGROUND: Positive bone margins have been shown to be associated with worse locoregional control and survival performance in oral oncology patients. With the application of computer-assisted surgery and patient-specific surgical guides, the authors can accurately execute the preoperative osteotomy plan. However, how well the authors can predict the margin distance in the final histopathology with a preoperative computed tomography (CT) scan, the factors associated with it, and how much leeway CT should spare when designing the osteotomy planes during virtual surgical planning (VSP) remain to be investigated. MATERIALS AND METHODS: Patients from January 2021 to December 2022 with benign or malignant jaw tumors and with signs of bone marrow involvement in the preoperative CT scan in our center were prospectively recruited to the study. VSP and measurement of the closest margin distance in the CT scan were performed by the single team of surgeons. The resection specimen was processed, and the margin distances were measured by a dedicated senior pathologist with the knowledge of orientation of the osteotomy planes. RESULTS: A total of 35 patients were recruited, with 21 malignant and 14 benign cases. Sixty-eight bone margins were quantitatively analyzed. No significant difference in margin distances measured from the CT scan and final histopathology was detected ( P =0.19), and there was a strong correlation between the two (r s =0.74, P <0.01). A considerable amount of variance was detected in the level of discrepancy between margin distances measured in the CT scan and final histopathology (overall SD=6.26 mm, malignancy SD=7.44 mm, benign SD=4.40 mm). No significant correlation existed between the two margin distances when only maxilla tumor margins were assessed ( P =0.16). CONCLUSION: The bone margin distance in VSP is reliably correlated to the final pathological margin distance. A leeway distance of 15mm and 9mm should be considered when designing the osteotomy planes for malignancy and benign cases, respectively. Extra attention should be paid to maxilla cases when predetermining the osteotomy planes during VSP.

OBJECTIVES: Microvascular bone flap jaw reconstruction has achieved satisfactory clinical outcomes. However, little is known about the long-term stability of the reconstructed jaw. This prospective longitudinal study aimed to investigate the long-term stability of jaw reconstruction and factors that were associated with it. METHODS: Patients with successful computer-assisted osseous free-flap jaw reconstruction in the Department of Oral and Maxillofacial Surgery, Queen Mary Hospital, Hong Kong were recruited for this prospective longitudinal study. The three-dimensional jaw models at the pre-operative plan, post-operative 1-month, and 2 years were aligned and compared. RESULTS: A total of 69 patients were recruited, among which 48 patients were available for the long-term analysis. Compared to 1-month after surgery, further deviation from the pre-operative plan was observed at post-operative 2 years. Lack of accuracy in surgery, segmental mandible resection especially with the involvement of mandible angles, and post-operative radiation therapy were identified as the significant factors affecting the positional stability of the reconstructed jaw (p < 0.05). Stable reconstruction was observed in the subgroup analysis of patients without post-operative radiation therapy. CONCLUSION: Up to the best of our knowledge, this is the first prospective longitudinal study reporting the long-term stability of jaw reconstruction and its affecting factors. Our data demonstrated that the reconstructed jaw position lacked stability over the postoperative period. How to improve long-term stability of reconstructed jaw thus optimize the functional outcomes warrants further studies.

OBJECTIVES: The rapidly ageing world has placed considerable demands on health and social care. To address this, the World Health Organization (WHO) and United Nations (UN) have declared action for this decade (2021-2030) to promote healthy ageing. Operationalisation of successful ageing in the oral health context in terms of its dimensions and their interconnectedness was determined. METHODS: A citation analysis was conducted following a scoping review to determine oral health's relationship with 5 key dimensions of successful ageing. This included examining the occurrence and co-occurrence amongst dimensions and over time. Specific consideration of citations by country, journal type, and authors through overlay visualisation was performed to map their interconnectedness. RESULTS: The scoping review identified 263 publications covering 1730 specific terms. There was a growing interest in successful ageing in the oral health context, mostly in the past decade (2010 onwards; 65.8%, 173 publications). The dimension of key consideration was "health and ADLs" (activities of daily living); this dimension appeared in 97.3% of publications (n = 256) and was found earliest to emerge, with the greatest link strengths compared to other dimensions. Country-level variations in citation data were observed, and there was good citation interconnectedness between them. Key oracles for dissemination have been medical rather than dental-specific journals. Amongst authors, there was considerable interconnectedness in the field. CONCLUSIONS: Findings highlight how successful ageing in the oral health context has been studied, with implications for addressing the significance of oral health to older peoples' lives in line with the WHO and UN's agenda. Citation analyses identified the "known unknowns" area for further consideration, and these findings have the potential to inform how dental research may best move forward with the successful ageing agenda to bring about translational impact.
RESUMO
BACKGROUND: Vascular alterations are present in pregnant women affected by preeclampsia. In this study, we assessed arterial compliance in women affected by hypertensive disorders of pregnancy. We hypothesized that arterial compliance is reduced in women affected by preeclampsia. METHODS: Forty-three hypertensive pregnant women undergoing evaluation for preeclampsia were studied. Clinical data about each patient and pregnancy were collected. Large (C1) and small (C2) artery compliance were assessed by radial tonometry, while the patients underwent laboratory tests to diagnose preeclampsia. At the time of delivery, gestational age and newborn data were recorded. RESULTS: Eighteen women were diagnosed with preeclampsia. C2 levels were lower among preeclamptic versus hypertensive aproteinuric women (mean ± SD, 4.5 ± 1.3 vs 5.9 ± 2.3 mL/mm Hg · 100, P = 0.013, 95% confidence interval [CI] of difference 0.32-2.55), whereas C1 levels did not differ. In the preeclampsia group, C2 levels correlated with urine total protein concentrations measured the same day (Spearman ρ = -0.49, P = 0.047, upper 95% CI -0.01) and with gestational age at first occurrence of hypertension (Spearman ρ = 0.59, P = 0.010, lower 95% CI 0.17). Among singleton gestations, C2 also correlated with newborn birth weight measured at delivery (Spearman ρ = 0.43, P = 0.009, lower 95% CI 0.11). Women who were hypertensive but aproteinuric at the time of compliance assessment, but who subsequently developed preeclampsia (n = 6), had C2 levels similar to those with an early diagnosis of preeclampsia (mean difference 0.37 mL/mm Hg · 100, 95% CI -2.42 to 1.67) and lower C2 levels than women diagnosed with gestational hypertension (P = 0.019, 95% CI 0.33-4.42 mL/mm Hg · 100). CONCLUSIONS: The noninvasive assessment of arterial elasticity may contribute toward characterization of the nature of the pathophysiology in pregnancy-induced hypertensive disorders. The vascular alterations of the small arteries, as assessed by C2, may reflect the extent of vascular alterations present with preeclampsia.

BACKGROUND: Sense of coherence (SOC) is hypothesized to be an important psychological factor that enables people to cope with stressors and successfully maintain and improve health. Mother's SOC has been shown to be an important psychological factor associated with oral health and oral health-related behaviors of adolescents and 11- to 12-year-old children. However, little is known about the relationship between the caregiver's SOC and oral health-related behaviors of the preschool children. The objective of this study was to investigate the relationship between oral health-related behaviors of 5-year-old children in Southern China and SOC of their caregiver. METHODS: A cross-sectional study was conducted in a randomized sample of 1332 children aged 5 years and their caregivers in Guangzhou, Southern China. Data were collected through questionnaires completed by the caregivers. The Chinese short version of Antonovsky's SOC scale (13 items) was employed to assess the caregiver's SOC. The outcome variables were the child's oral health-related behaviors, including frequency of sugary snack intake, toothbrushing frequency, utilization of dental service, and pattern of dental visits. Multiple logistic regression was used to analyze the relationship between the variables. RESULTS: No association was found between the children's sugary snack intake and the mother's or the father's SOC. After adjustment for other significant factors related to the child's oral health-related behaviors, 8.9% of the children whose grandparents (as caregivers) had higher SOC scores had a lower frequency of sugary snack intake, compared with the children whose grandparents had lower SOC scores (OR = 0.61, 95% CI = 0.50-0.73, p = 0.008). The other measures of oral health-related behaviors of the child were not significantly associated with the caregiver's SOC. CONCLUSION: Sugary snack intake behavior of the 5-year-old children was not associated with the mother's or the father's SOC. It was associated with the SOC of their grandparents, who are a small group of the caregivers in China.

STUDY OBJECTIVE: Use of cognitive aids during emergencies increases key actions and decreases omissions, both known to save lives. With little known about emergency manual (EM) clinical use, we aimed to help answer "Will EMs be used peri-crisis at a meaningful frequency?" and to explore clinical sustainment. DESIGN: Prospective, observational study. SETTING: Operating Rooms. PATIENTS: All patients undergoing anesthesia at a major academic medical center during the study periods; â¼75,000 cases. INTERVENTION & MEASUREMENTS: To understand the initial and sustainment phases of EM implementation, we placed a question regarding EM use at the end of every anesthetic case to prospectively measure EM use at: implementation, one-year later, and six years post-implementation. MAIN RESULTS: For more than twenty-four thousand cases in each approximately 6-month study period, EMs were used peri-crisis (before, during or after a perioperative crisis) in 145 cases initially (0.55%; SE 0.045%), 42 cases one-year later (0.17%; SE 0.026%), and 57 cases (0.21%; SE 0.028%) six years post-implementation. Peri-crisis EM uses dropped 0.38% (97.5% CI: 0.26%, 0.49%) from initial to one-year post-implementation. After that, peri-crisis EM uses did not differ significantly from one-year to six years post-implementation, showing sustainment [increased 0.04% (97.5% CI: -0.05%, 0.12%)]. Among cases with cardiac arrest or CPR, as a subset proxy for relevant crises, EMs were used in 7/13 such cases initially (54%, SE 13.6%), 8/20 one-year later (40%; SE 10.9%) and 7/13 six years later (54%; SE 13.6%). CONCLUSIONS: After an initial expected drop, EM peri-crisis use six years post-implementation was: sustained without intensive additional efforts, averaged â¼10 times per month at a single institution, and was reported in more than half of cases with cardiac arrest or CPR. Peri-crisis use of EMs is appropriately rare, though for relevant crises can have substantial positive impacts as described in prior literature. The sustained use of EMs may be related to increasing cultural acceptance of EMs, as reflected in survey result trends and broader cognitive aid literature.

BACKGROUND: Removal of teeth results in both horizontal and vertical changes of hard and soft tissue dimensions. The magnitude of these changes is important for decision-making and comprehensive treatment planning, with provisions for possible solutions to expected complications during prosthetic rehabilitation. OBJECTIVES: To review all English dental literature to assess the magnitude of dimensional changes of both the hard and soft tissues of the alveolar ridge up to 12 months following tooth extraction in humans. METHODS: An electronic MEDLINE and CENTRAL search complemented by manual searching was conducted to identify randomized controlled clinical trials and prospective cohort studies on hard and soft tissue dimensional changes after tooth extraction. Only studies reporting on undisturbed post-extraction dimensional changes relative to a fixed reference point over a clearly stated time period were included. Assessment of the identified studies and data extraction was performed independently by two reviewers. Data collected were reported by descriptive methods. Weighted means and percentages of the dimensional changes over time were calculated where appropriate. RESULTS: The search provided 3954 titles and 238 abstracts. Full text analysis was performed for 104 articles resulting in 20 studies that met the inclusion criteria. In human hard tissue, horizontal dimensional reduction (3.79 ± 0.23 mm) was more than vertical reduction (1.24 ± 0.11 mm on buccal, 0.84 ± 0.62 mm on mesial and 0.80 ± 0.71 mm on distal sites) at 6 months. Percentage vertical dimensional change was 11-22% at 6 months. Percentage horizontal dimensional change was 32% at 3 months, and 29-63% at 6-7 months. Soft tissue changes demonstrated 0.4-0.5 mm gain of thickness at 6 months on the buccal and lingual aspects. Horizontal dimensional changes of hard and soft tissue (loss of 0.1-6.1 mm) was more substantial than vertical change (loss 0.9 mm to gain 0.4 mm) during observation periods of up to 12 months, when study casts were utilized as a means of documenting the changes. CONCLUSIONS: Human re-entry studies showed horizontal bone loss of 29-63% and vertical bone loss of 11-22% after 6 months following tooth extraction. These studies demonstrated rapid reductions in the first 3-6 months that was followed by gradual reductions in dimensions thereafter.
