Prevalence of interpersonal violence against children in sport in six European countries.

BACKGROUND: Investigating prevalence of child abuse in sport is a relatively new field of research, born from the need for credible data on this phenomenon. OBJECTIVE: To establish prevalence rates of interpersonal violence against children in sport in six European countries. PARTICIPANTS AND SETTING: The sample (N = 10,302) consists of individuals aged 18-30 who had participated in organized sport prior to age 18 (49.3 % male, 50 % female). METHODS: A self-report questionnaire was developed (the Interpersonal Violence Against Children in Sport Questionnaire or IVACS-Q) to measure prevalence of five categories of interpersonal violence (neglect, psychological violence, physical violence, non-contact sexual violence, and contact sexual violence) against children who participate in sport. Validation testing (published separately) showed reasonable levels of convergent and divergent validity. Prevalence rates are calculated by national context, whether inside or outside sport, and by sex (male/female). RESULTS: Prevalence of IVACS inside sport differed by category: psychological violence (65 %, n = 6679), physical violence (44 %, n = 4514), neglect (37 %, n = 3796), non-contact sexual violence (35 %, n = 3565), and contact sexual violence (20 %, n = 2060). Relatively small geographical differences were found. Across all categories, males (79 %, n = 4018) reported significantly more experiences inside sport than females (71 %, n = 3653) (χ2(1) = 92.507, p < .000). Strong correlations were found between experiencing violence inside and outside sport. CONCLUSIONS: Interpersonal violence against children in sport is widespread. The sector's approach to prevention must recognize the risks to female and male children (and all children) and the additional vulnerabilities of abused children. Further comparative and longitudinal research within sport is required.

Metabolic landscape of the male mouse gut identifies different niches determined by microbial activities.

Distinct niches of the mammalian gut are populated by diverse microbiota, but the contribution of spatial variation to intestinal metabolism remains unclear. Here we present a map of the longitudinal metabolome along the gut of healthy colonized and germ-free male mice. With this map, we reveal a general shift from amino acids in the small intestine to organic acids, vitamins and nucleotides in the large intestine. We compare the metabolic landscapes in colonized versus germ-free mice to disentangle the origin of many metabolites in different niches, which in some cases allows us to infer the underlying processes or identify the producing species. Beyond the known impact of diet on the small intestinal metabolic niche, distinct spatial patterns suggest specific microbial influence on the metabolome in the small intestine. Thus, we present a map of intestinal metabolism and identify metabolite-microbe associations, which provide a basis to connect the spatial occurrence of bioactive compounds to host or microorganism metabolism.

Long-term Outcome of Pediatric Liver Transplant Recipients Who Have Reached Adulthood: A Single-center Experience.

BACKGROUND: As long-term survival of pediatric liver transplant recipients increases, the assessment of physical, psychological, and social well-being becomes more important. METHODS: In this retrospective analysis, 120 young adult patients (age ≥18 y) who underwent liver transplantation in childhood were studied. Patients with ideal outcome were defined as patients with perfect graft function, with no complications from the immunosuppressive medication, no late retransplantation, and no steroid treatment. Also, the patients' drug adherence and their psychosocial situation were assessed. RESULTS: After a median follow-up of 19 y, only 16.7% of the patients (mean age: 26.5 y) were considered patients with ideal outcome. The main reasons precluding ideal outcome were chronic kidney disease (38.3%), elevated liver enzymes (33.3%), and arterial hypertension (31.7%). Ideal outcome decreased over time from 54% to 42%, 26%, and 8% at 10-, 15-, 20-, and 25-y follow-up, respectively. Reduced drug adherence was noted in 24.8% of patients and associated with a significantly higher prevalence of donor-specific antibodies class II ( P = 0.015), elevated transaminases ( P = 0.010), and chronic rejection ( P < 0.001). Also, 15% of patients had a psychiatric disease, mainly depression. CONCLUSIONS: The morbidity of young adults who underwent liver transplantation as children was high and increased over time. The majority developed complications from immunosuppression or chronic graft dysfunction. More than 1 in 7 patients had a psychiatric disease and 1 in 4 was not perfectly drug adherent. Therefore, immunosuppressive treatment and psychological care should be optimized for these particularly vulnerable patients.

Measuring Adherence to Antibiotic Use Guidelines in Managing Mandible Fractures.

PURPOSE: Due to variability in practice patterns when managing patients with facial fractures, the Surgical Infection Society's Therapeutics and Guidelines Committee (SIS) released guidelines in June 2020 concerning antibiotic use in the treatment of patients with facial fractures. The purpose of this study was to measure adherence to SIS guidelines among patients treated for isolated mandibular fractures and to identify factors associated with deviation from SIS guidelines. MATERIALS AND METHODS: The authors designed and implemented a retrospective cohort study and enrolled a sample derived from the population of patients treated for isolated mandibular fractures at Harborview Medical Center (Seattle, WA) and University of Washington Medical Center-Montlake (Seattle, WA) from June 2020 through October 2021. The primary outcome variable was adherence to SIS antibiotic guidelines (yes or no). Covariates were grouped into the following categories: demographic (age, gender), treatment (operative treatment, primary service, transfer status), and risk factor (Charlson Comorbidity Index, tobacco use, alcohol use, drug use other than marijuana, mandibular injury severity score). Descriptive and bivariate statistics were computed to measure the association between adherence and the study variables. The level of statistical significance was set at a P-value ≤.05. RESULTS: The study sample was composed of 114 patients with a mean age of 41.8 ± 19.0 years and 72% were males. The frequency of adherence to SIS antibiotic protocol was 91.2%. Variables associated with deviation from SIS antibiotic protocol were operative treatment (P-value = .03 - relative risk (RR) not calculable), current drug use other than marijuana (RR = 4.1; 95% confidence interval, 1.3-12.8; P-value = .01), and transfer from an outside facility (RR = 4.1; 95% confidence interval, 1.3-12.8; P-value = .01). CONCLUSIONS: The findings of this study suggest that the SIS antibiotic guidelines in the management of isolated mandible fractures were translated well into practice at our institution as evidenced by the high level of compliance (>90%). To improve adherence, additional research is indicated to better understand how factors such as treatment choice, drug exposure, and transfer status adversely affect adherence to guidelines.

Imposing Compulsory Rugby Union on Schoolchildren: An Analysis of English State-Funded Secondary Schools.

Objective: To establish the extent to which Rugby Union was a compulsory physical education activity in state-funded secondary schools in England and to understand the views of Subject Leaders for Physical Education with respect to injury risk. Method: A cross-sectional research study using data obtained under the Freedom of Information Act (2000) from 288 state-funded secondary schools. Results: Rugby Union was delivered in 81% (n = 234 of 288) of state-funded secondary school physical education curricula, including 83% (n = 229 of 275) of state-funded secondary school boys' and 54% (n = 151 of 282) of girls' physical education curricular. Rugby Union was compulsory in 91% (n = 208 of 229) of state-funded secondary schools that delivered it as part of the boys' physical education curriculum and 54% (n = 82 of 151) of state-funded secondary schools that delivered contact Rugby Union as part of the girls' physical education curriculum. Subject Leaders for Physical Education also perceived Rugby Union to have the highest risk of harm of the activities they delivered in their school physical education curriculum. Conclusion: Notwithstanding discussions of appropriate measures (i.e., mandatory concussion training, Rugby Union specific qualifications and CPD) to reduce injury risk, it is recommended that Rugby Union should not be a compulsory activity given that it has a perceived high risk of injury and is an unnecessary risk for children in physical education.

Workplace bullying, burnout and resilience amongst perioperative nurses in Australia: A descriptive correlational study.

AIM: This study aimed to investigate workplace bullying and explore correlations between bullying, burnout and resilience amongst perioperative nurses in Australia. BACKGROUND: Workplace bullying in perioperative nursing involves verbal, physical and psychological violence. However, no prior studies have measured Australian perioperative nurses' experiences of workplace bullying nor sought to understand if there is a relationship with burnout and resilience. METHODS: A descriptive correlational study was conducted utilizing an online survey incorporating four validated instruments. Descriptive statistics and regression models analysed workplace bullying, burnout and resilience. RESULTS: Over half of perioperative nurses (n = 158/257, 61%) were exposed to workplace bullying. Consequences included fatigue and exhaustion (n = 129/192, 67%), anxiety (n = 123/192, 64%) and sleeplessness (n = 121/192, 63%). Organisational processes (r = .458, p < .001), bullying acts (r = .289, p < .001) and avoidance and withdrawal at work (r = .440, p = .001) increased burnout. Psychosocial distress (r = -.216, p < .001) was associated with decreased resilience. CONCLUSIONS: Workplace bullying is a persistent issue with negative impacts upon burnout, resilience and well-being. IMPLICATIONS FOR NURSING MANAGEMENT: The psychological well-being of employees can be prioritized by establishing and maintaining an organisational climate of psychosocial safety, thereby inhibiting the potential of bullying to manifest and positively influencing employee well-being to help promote workplace engagement, productivity and reduced burnout.

Management of Panfacial Trauma: Sequencing and Pitfalls.

Panfacial trauma refers to high-energy mechanism injuries involving two or more areas of the craniofacial skeleton, the frontal bone, the midface, and the occlusal unit. These can be distracting injuries in an unstable patient and, as in any trauma, Advanced Trauma Life Support (ATLS) protocols should be followed. The airway should be secured, bleeding controlled, and sequential examinations should take place to avoid overlooking injuries. When indicated, neurosurgery and ophthalmology should be consulted as preservation of brain, vision, and hearing function should be prioritized. Once the patient is stabilized, reconstruction aims to reduce panfacial fractures, restore the horizontal and vertical facial buttresses, and resuspend the soft tissue to avoid the appearance of premature aging. Lost or comminuted bone can be replaced with bone grafts, although adequate reduction should be ensured prior to any grafting. Operative sequencing can be performed from top-down and outside-in or from bottom-up and inside-out depending on patient presentation. All protocols can successfully manage panfacial injuries, and the emphasis should be placed on a systematic approach that works from known areas to unknown areas.

[Severe secondary sclerosing cholangitis as manifestation of a very rare underlying disease]. / Schwere sekundär sklerosierende Cholangitis als Manifestation einer sehr seltenen Grunderkrankung.

Langerhans cell histiocytosis (LCH) is a very rare cause of secondary sclerosing cholangitis. We report the case of a 42-year-old male patient with sclerosing cholangitis and histological evidence of LCH from a bile duct biopsy. Due to rapid disease progression and exhaustion of conservative therapeutic approaches the patient received a liver transplantation. Nearly 2 years after transplantation the patient has a good graft function and no signs of recurrence of the underlying LCH.

Psychosocial situation, adherence, and utilization of video consultation in young adult long-term pediatric liver transplant recipients during COVID-19 pandemic.

BACKGROUND: Young adults who underwent liver transplantation in childhood (YALTs) are highly vulnerable to non-adherent behavior and psychosocial problems. During the COVID-19 pandemic, special efforts may be necessary to maintain contact with these patients and offer support. This can be achieved through the use of telemedicine. The study's objective was to assess adherence and the psychosocial situation of YALTs during the COVID-19 pandemic in Germany and to evaluate the utilization of video consultations. METHODS: In May 2020, a questionnaire was sent to YALTs treated at the Hamburg University Transplant Center, accompanied by the offer of video appointments with the attending physician. The questionnaire included the Generalized Anxiety Disorder Scale 7, the Patient Health Questionnaire 2, and questions compiled by the authors. RESULTS: Of 98 YALTs, 12% used the video consultation, while 65% had an in-person appointment. The 56 patients who completed the questionnaire did not report reduced medication adherence during the pandemic, but 40% missed follow-up visits with their primary care physician or check-up laboratory tests. About 70% of YALTs were afraid to visit their physician and the transplant center, and 34% were afraid of a SARS-CoV-2 infection. Mental health and well-being were unimpaired. CONCLUSIONS: During the COVID-19 pandemic, YALTs in our study did not show an increased need for psychosocial support, but a majority were afraid to attend medical appointments, and 40% reported lower appointment adherence. Acceptance of video consultations was lower than expected. The reasons for this need to be further investigated in order to optimize care.

Is Distance Between Home and Treatment Site a Risk Factor for Complications After Treating Mandibular Fractures?

PURPOSE: Our level I trauma center provides care over a large geographic area including Alaska, Washington, Idaho, Montana, and Wyoming, with many patients traveling hundreds of miles to receive care. Distance to a treatment site is documented to be an independent risk factor for complications after multisystem trauma, but it is unclear if it is a risk factor for isolated mandibular fractures. The study purpose was to measure the association between distance to treatment site and risk for postoperative complications after treatment of isolated mandibular fractures. MATERIALS AND METHODS: The investigators designed and implemented a retrospective cohort study and enrolled a sample derived from patients treated for isolated mandibular fractures at Harborview Medical Center by the oral and maxillofacial surgery service between June 2012 and December 2016. The primary predictor variable was distance (miles) between the patient's residence and site of treatment (Harborview Medical Center). The primary outcome variable was postoperative complication (yes or no), subcategorized as major and minor. Secondary outcome variables were time to treatment between injury and operative treatment (days) and length of hospital stay (LOS) (days). Descriptive, bivariate, and multiple logistic regression statistics were computed to measure the association between distance to treatment site and postoperative complications, time to treatment, and LOS. The level of statistical significance was set at P ≤ .05. RESULTS: The study sample was composed of 403 subjects with a mean age of 32.6 ± 14.3 years and 80% were men. The average distance from the patient's residence to treatment site was 44.8 ± 128.6 miles (range, 0 to 1,440 miles; median, 20.4 miles). Major complications occurred in 11.6% of patients. The average distance between patients with and without postoperative complications was not significantly different (42.3 ± 55.8 miles vs 45.5 ± 141.7 miles; P = .8). Increasing distance was significantly associated with longer LOS (r = 0.16; P < .001) but not time to treatment (r = .04; P = .4). CONCLUSIONS: In contrast to other studies regarding multisystem trauma, complications after treating isolated mandible fractures were not associated with increasing distance to treatment site. Increasing distance may be associated with longer LOS but not time to treatment.

What Is the Effect of COVID-19-Related Social Distancing on Oral and Maxillofacial Trauma?

PURPOSE: The purpose of this study was to understand the impact of social distancing policies enacted during the COVID-19 pandemic on the epidemiology of oral and maxillofacial fractures at an urban, Level I trauma center in the United States. MATERIALS AND METHODS: The investigators designed a retrospective cohort study and enrolled a sample of 883 subjects who presented for evaluation of oral and maxillofacial fractures (OMF) between March 1 and June 30 in the years 2018 through 2020. The primary predictor variable was the evaluation of OMF during a period with social distancing policies (2020 - experimental group) or without social distancing policies in place (2018 or 2019 - control group). The primary outcome variables were the facial fracture diagnosis, the abbreviated injury scale (AIS), injury severity score (ISS), and the mechanism of injury. Appropriate univariate and bivariate statistics were computed, and the level of significance was set at P < .05 for all tests. RESULTS: The number of subjects presenting with OMF was lower during the period of social distancing (n = 235 in 2020) than during the periods without (2018: n = 330; 2019: n = 318). During the period of social distancing, there were more individuals who presented secondary to assault, whereas fewer individuals presented secondary to falls (P = .05). On average, those who presented in 2020 had more severe oral and maxillofacial injuries (mean AIS = 3.2 ± 1.2 in 2020 vs 3.0 ± 1.1 in 2019 and 3.0 ± 1.1 in 2018. P = .03) and more overall injuries (mean ISS = 20.7 ± 13.1 in 2020 vs 19.2 ± 12.5 in 2019; 17.8 ± 12.8 in 2018. P = .03). CONCLUSIONS: The investigators found that during the period of social distancing through the COVID-19 pandemic, the number of OMF cases decreased but that the severity of oral and maxillofacial and overall injuries was higher.

Impaired diagnostic accuracy of hair ethyl glucuronide testing in patients with renal dysfunction.

The impact of renal impairment and hemodialysis on ethyl glucuronide concentrations in hair (hEtG) is not well known. Here, hEtG levels were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in patients presenting to the transplant outpatient clinic and compared with the self-reported alcohol consumption in an anonymous validated questionnaire. Estimated daily alcohol intake (EDI) was calculated. A total of 94 patients with varying renal function (Glomerular filtration rate (GFR) > 60 mL/min: group 1 (n = 47); GFR 30-60 ml/min: group 2 (n = 29); GFR < 30 mL/min: group 3 (n = 18)) were included in the study. Fifteen of 18 (83.3%) patients in group 3 were on dialysis. Altogether, hEtG tested positive (> 5 pg/mg) in 25.5% (n = 24) of patients, while 36.2% (n = 34) and 14.9% (n = 14) of patients reported any or regular (> 10 g/d) alcohol consumption, respectively. The median hEtG concentration of positive samples was much higher in patients in group 3 with advanced renal dysfunction or on dialysis than in patients in group 1 or 2 (group 1, 2, 3 dialysis patients: 74, 52, 145 and 155 pg/mg, respectively), although they consumed on average much less alcohol per day (median EDI group 1, 2, 3, dialysis patients: 16, 17, 3 and 3 g/d, respectively). Also, there was a significant correlation between the hEtG concentration and EDI for patients in group 1 (ρ = 0.84; p = 0.01), but not for patients in group 2 (ρ = -0.35, p = 0.39) or 3 (ρ = 0.02, p = 0.96). Furthermore, the ability of hEtG to correctly identify abstainers as such was lower for patients with advanced renal dysfunction than for the remaining patients (specificity for group 1, 2, 3: 92%, 87%, 82%, respectively). So, monitoring hEtG concentration was less reliable in patients with advanced renal dysfunction or on hemodialysis and by far overestimated the amount of alcohol consumed.

Exploring the role of nurses in after-hours telephone services in regional areas; A scoping review.

INTRODUCTION: The management of patients who need chronic and complex care is a focus of attention internationally, brought about by an increase in chronic conditions, requiring significantly more care over longer periods of time. The increase in chronic conditions has placed pressure on health services, financially and physically, bringing about changes in the way care is delivered, with hospital avoidance and home-based care encouraged. In this environment, nurses play an important role in co-ordinating care across services. This review formed one part of a funded project that explored the nurse navigator role within a proposed 24-hour telephone-call service in one regional area that has a diverse population in terms of cultural identity and geographical location in relation to service access. AIM: The review reports on the extant literature on the nurse's role in the provision of afterhours telephone services for patients with chronic and complex conditions. The specific aim was to explore the effectiveness of services for patients in geographically isolated locations. METHODS: The methodological approach to the review followed the Preferred Reporting System for Meta-Analyses (PRISMA) guidelines. A thematic analysis was used to identify themes with chronic care models underpinning analysis. RESULTS: Three themes were identified; nurse-led decision making; consumer profile; and program outcomes. Each theme was divided into two sub-themes. The two sub-themes for decision making were: the experience of the staff who provided the service and the tool or protocol used. The two sub-themes for consumers profile were; the geographic/demographic identity of the consumers, and consumer satisfaction. The final theme of outcomes describes how the effectiveness of the service is measured, broken into two sub-themes: the economic/workforce outcomes and the consumer outcomes. DISCUSSION: The provision of an after-hours telephone service, in whatever model used should align with a Chronic Care Model. In this way, after-hours telephone services provided by experienced nurses, supported by ongoing professional development and relevant protocols, form part of the ongoing improvement for chronic and complex care management as a health priority.

The use of telephone communication between nurse navigators and their patients.

BACKGROUND: Hospitals and other health care providers frequently experience difficulties contacting patients and their carers who live remotely from the town where the health service is located. In 2016 Nurse Navigator positions were introduced into the health services by Queensland Health, to support and navigate the care of people with chronic and complex conditions. One hospital in Far North Queensland initiated an additional free telephone service to provide another means of communication for patients and carers with the NNs and for off-campus health professionals to obtain details about a patient utilising the service. Calls made between 7am and 10pm, seven days per week are answered by a nurse navigator. AIM: To report utilisation of the service by navigated clients and remotely located clinicians compared to use of navigators' individual work numbers and direct health service numbers. We report the reason for calls to the free number and examine features of these calls. METHODS: Statistical analysis examined the call reason, duration of calls, setting from where calls originated and stream of calls. Interactions between the reasons for calls and the features of calls, such as contact method, were examined. RESULTS: The major reason for calls was clinical issues and the source of calls was primarily patients and carers. Clinical calls were longer in duration. Shorter calls were mainly non-clinical, made by a health professional. Setting for calls was not related to the reason. The most frequent number used was the individual mobile number of the NN, followed by the hospital landline. Although the free number was utilised by patients and carers, it was not the preferred option. CONCLUSION: As patients and carers preferred to access their NN directly than via the 1800 number, further research should explore options best suited to this group of patients outside normal business hours.

Are Oral and Maxillofacial Surgeons Prescribing Fewer Opioids and More Non-Narcotic Analgesics for Postoperative Pain After Third Molar Removal?

PURPOSE: In response to the national opioid epidemic crisis, the purpose of this study was to measure changes in opioid and non-narcotic analgesia (NNA) prescribing practices over time after third molar (M3) removal. MATERIALS AND METHODS: A retrospective double cohort study was utilized enrolling 2 samples of patients who had M3s removed during 2 different 3-month intervals. The primary predictor variable was prescribing practice, divided into cohorts: 1) previous prescribing practice (PPP) occurring early during the evolving opioid epidemic (2014); and 2) current prescribing practice (CPP) (2018). The outcome measures were morphine milligram equivalents (MMEs), NNA prescriptions, and refill MMEs for inadequate pain control (IPC). Other variables were age, gender, payor, provider, anesthesia, procedure, and number of M3s removed. Descriptive, bivariate, and multiple linear and logistic regression models were computed. RESULTS: The sample included 330 subjects with a mean age of 23.1 ± 8.1 years; 42.4% were male. Of the 330 subjects, 147 were in the PPP cohort (44.5%) and 183 in CPP cohort (55.5%). Mean MMEs were 130.1 ± 42.4 and 68.5 ± 32.0 in the PPP and CPP cohorts, respectively (P ≤ .001). An adjusted linear regression model showed differences in MMEs prescribed persisted (P ≤ .001). The frequency of postoperative NNA prescriptions written increased from 2.7 to 71.6% (P ≤ .001). An adjusted logistic regression model also revealed that NNA prescriptions had significantly increased (odds ratio, 242.00; P ≤ .001). No difference was found in the frequency of refills for IPC (P = .13) or mean refill MME prescriptions between the cohorts (P = .48). CONCLUSIONS: Within our academic practice, fewer opioids and more NNAs are being prescribed for postoperative pain after M3 removal without an increase in IPC. Increased awareness through prescribing regulations, non-narcotic research findings, and organizational guidelines could have contributed to these changes.

Evidence-based clinical practice guideline on antibiotic use for the urgent management of pulpal- and periapical-related dental pain and intraoral swelling: A report from the American Dental Association.

BACKGROUND: An expert panel convened by the American Dental Association Council on Scientific Affairs and the Center for Evidence-Based Dentistry conducted a systematic review and formulated clinical recommendations for the urgent management of symptomatic irreversible pulpitis with or without symptomatic apical periodontitis, pulp necrosis and symptomatic apical periodontitis, or pulp necrosis and localized acute apical abscess using antibiotics, either alone or as adjuncts to definitive, conservative dental treatment (DCDT) in immunocompetent adults. TYPES OF STUDIES REVIEWED: The authors conducted a search of the literature in MEDLINE, Embase, the Cochrane Library, and the Cumulative Index to Nursing and Allied Health Literature to retrieve evidence on benefits and harms associated with antibiotic use. The authors used the Grading of Recommendations Assessment, Development and Evaluation approach to assess the certainty in the evidence and the Evidence-to-Decision framework. RESULTS: The panel formulated 5 clinical recommendations and 2 good practice statements, each specific to the target conditions, for settings in which DCDT is and is not immediately available. With likely negligible benefits and potentially large harms, the panel recommended against using antibiotics in most clinical scenarios, irrespective of DCDT availability. They recommended antibiotics in patients with systemic involvement (for example, malaise or fever) due to the dental conditions or when the risk of experiencing progression to systemic involvement is high. CONCLUSION AND PRACTICAL IMPLICATIONS: Evidence suggests that antibiotics for the target conditions may provide negligible benefits and probably contribute to large harms. The expert panel suggests that antibiotics for target conditions be used only when systemic involvement is present and that immediate DCDT should be prioritized in all cases.

Antibiotics for the urgent management of symptomatic irreversible pulpitis, symptomatic apical periodontitis, and localized acute apical abscess: Systematic review and meta-analysis-a report of the American Dental Association.

BACKGROUND: Patients with pulpal and periapical conditions often seek treatment for pain, intraoral swelling, or both. Even when definitive, conservative dental treatment (DCDT) is an option, antibiotics are often prescribed. The purpose of this review was to summarize available evidence regarding the effect of antibiotics, either alone or as adjuncts to DCDT, to treat immunocompetent adults with pulpal and periapical conditions, as well as additional population-level harms associated with antibiotic use. TYPE OF STUDIES REVIEWED: The authors updated 2 preexisting systematic reviews to identify newly published randomized controlled trials. They also searched for systematic reviews to inform additional harm outcomes. They conducted searches in MEDLINE, Embase, the Cochrane Library, and the Cumulative Index to Nursing and Allied Health Literature. Pairs of reviewers independently conducted study selection, data extraction, and assessment of risk of bias and certainty in the evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS: The authors found no new trials via the update of the preexisting reviews. Ultimately, 3 trials and 8 additional reports proved eligible for this review. Trial estimates for all outcomes suggested both a benefit and harm over 7 days (very low to low certainty evidence). The magnitude of additional harms related to antibiotic use for any condition were potentially large (very low to moderate certainty evidence). CONCLUSIONS AND PRACTICAL IMPLICATIONS: Evidence for antibiotics, either alone or as adjuncts to DCDT, showed both a benefit and a harm for outcomes of pain and intraoral swelling and a large potential magnitude of effect in regard to additional harm outcomes. The impact of dental antibiotic prescribing requires further research.

Is the Mandible Injury Severity Score a Valid Measure of Mandibular Injury Severity?

PURPOSE: Developing a valid method for assessing mandibular injury severity could permit standardized comparisons of treatment-specific outcomes between and among various mandibular fracture studies. The study purpose was to assess the validity of the Mandible Injury Severity Score (MISS) developed by Shetty et al (J Oral Maxillofac Surg 65:663, 2007) by measuring the association between the MISS and postoperative complications, operative time, and length of hospital stay (LOS) after operative treatment of isolated mandibular fractures. MATERIALS AND METHODS: The authors designed and implemented a retrospective cohort study and enrolled a sample derived from patients treated for isolated mandibular fractures at Harborview Medical Center (Seattle, WA) by the oral and maxillofacial surgery service from June 2012 through December 2016. The primary predictor variable was the MISS. The primary outcome variable was postoperative complication (yes or no). Secondary outcome variables were operative time and LOS. Descriptive, bivariate, and multiple logistic regression statistics were computed to measure the association between the MISS and postoperative complications. The level of statistical significance was set at a P value less than or equal to .05. RESULTS: The study sample was composed of 415 patients with a mean age of 32.7 ± 14.3 years and 80% were men. The average MISS was 13.4 ± 3.5 (range, 6 to 25). The postoperative complication rate was 21%. The average MISS was significantly higher in patients with postoperative complications than in patients without complications (16.3 ± 3.3 vs 12.6 ± 3.1; P < .001). In the adjusted model, postoperative complications were significantly associated with an increasing MISS (odds ratio [OR] = 1.4; 95% confidence interval [CI], 1.3-1.6; P < .001) and open treatment (OR = 7.6; 95% CI, 1.6-35.6; P = .01). The MISS was positively correlated with operative time (r = 0.529; P < .001) and LOS (r = 0.114; P = .02). CONCLUSION: The results of this study suggest that the MISS may be a valid measurement of mandibular injury severity as evidenced by the positive correlation between the MISS and postoperative complications, duration of operation, and LOS.
