A review of the use of patient reported outcome measures (PROMS) in temporomandibular joint (TMJ) surgery. J Craniomaxillofac Surg 2024; 52:181-187. [PMID: 38143160 DOI: 10.1016/j.jcms.2023.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 10/09/2023] [Accepted: 11/23/2023] [Indexed: 12/26/2023] Open
Abstract
Temporomandibular joint (TMJ) surgery accounts for a significant number of patient episodes in oral and maxillofacial surgery, and treatment effectiveness is commonly assessed using measures of pain and mouth opening. Patient-reported outcome measures (PROMs) enable assessment of the patient's perspective and perception of the diseases and treatment outcomes. The purpose of this review was to assess the use of PROMs in TMJ surgery. A review of 3 databases (PubMed, OVID, Trip) was carried out to assess the use of PROMs when reporting on TMJ surgical interventions. Studies were limited to the English language, involving humans and at least one surgical intervention of the TMJ. A total of 214 articles met the inclusion and exclusion criteria, of which only 28 used 18 PROMs among them. Half of these PROMs were single-question visual analogue scales or Likert scales on quality of life and disability. The Oral Health Impact Profile and the Helkimo Clinical Dysfunction Index were the second most used (n = 3). PROMs were used most in studies on internal derangement (n = 9) and in cohort study designs (n = 26), but this was not statistically significant. In the majority of research on TMJ surgery, no PROMs are used, and when one is, there is a tendency to use weaker single-question PROMs as opposed to multi-question PROMs to assess outcomes. With the increasing importance of PROMs for assessing patients' perception of treatment outcomes, further research is needed to establish valid and reproducible PROMs for TMJ surgery.

Predictors and risk factors for admission to critical care in cervicofacial infections: a Maxillofacial Trainee Research Collaborative (MTReC) study. Br J Oral Maxillofac Surg 2023; 61:78-83. [PMID: 36513528 DOI: 10.1016/j.bjoms.2022.09.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 09/22/2022] [Accepted: 09/23/2022] [Indexed: 11/21/2022]
Abstract
Cervicofacial infections carry significant morbidity. Patients present on a broad spectrum of severity, with some requiring outpatient management and others admission to higher level care. Recognition of risk factors is helpful in decision making regarding the need for admission to higher level care. Prospective data were captured on 1002 patients in 25 centres across 17 regions of the United Kingdom (UK) by the Maxillofacial Trainee Research Collaborative (MTReC). Patients admitted to critical care were compared with those who received ward-level care. Multivariate and receiver operating characteristic curve analyses were used to identify predictors for critical care admission. Our results show that the best predictor for critical care admission is the presence of three or more features of airway compromise (AUC 0.779), followed by C-reactive protein (CRP) >100 mg/L (OR 2.70; 95% CI 1.59 to 4.58; p < 0.005), submandibular space involvement (OR 3.82; 95% CI 1.870 to 7.81; p = 0.003), white cell count (WCC) >12 × 109/ dl (1.05; 95% CI 1.01 to 1.10; p = 0.03), and positive systemic inflammatory response syndrome criteria (OR 2.78; CI 1.35 to 5.80; p = 0.006). Admission to critical care is multifactorial, however, the presence of three or more features of airway compromise is the best predictor. Awareness of this alongside other key clinical findings in cervicofacial infections may allow for the early recognition of patients who may require escalation to critical care.

Abstract
Abstract
Introduction
Bolton NHS Trust has a busy Emergency Department (ED) in the North West. 21% of attendances are patients aged over 65. Early specialist input is recognised for frail older adults. The goal of this quality improvement project was to readdress the admission/discharge bias and to improve the quality of care for older patients in ED. A referral pathway would be implemented, and frailty team embedded into ED.
Methods
Data was collected from November 2018 to January 2020. The Frailty service underwent multiple quality improvement plans using PDSA cycles. Absence of documentation of the Clinical Frailty Score (CFS) lead to inadequate identification of frailty in ED. Frailty ACPs were based in ED to develop inter-disciplinary working whilst delivering education programmes to staff. In conjunction, Consultant-led sessions were delivered to ED trainees. This intervention was assessed by auditing CFS within patient electronic notes. Subsequent PDSA cycles resulted in CFS posters displayed in ED, in conjunction with a referral pathway to identify suitable patients. CFS scores became embedded in electronic patient records. Geriatricians reviewed directly into ED. Interventions were evaluated.
Results
Documentation of CFS increased by 20%. Referrals increased from 0 in November 2018 to 147 in December 2020. In December 2020, 52% of the patients assessed by the Frailty team were discharged, 46% of those had been referred to medicine. During the study period, the referral criteria was unreliably followed. Often referrals followed informal discussions rather than the criteria pathway. Inclusion criteria was restrictive. Education sessions were well received.
Conclusion
Basing the frailty team into ED encouraged documentation and recognition of CFS. Repeated education sessions are required due to staff turnover. Geriatrician review within ED reduced admissions to medical beds. The referral pathway has been adapted and extended to Community partners. This intervention is ongoing and will require evaluation.

Abstract
One technique often used for small intraarticular fracture fixation involves the use of 2-octyl-cyanoacrylate (2-OCTA) (Dermabond®, Ethicon, Inc., Raritan, USA). The purpose of this study was to determine if 2-OCTA impedes bony healing. Osteochondral plugs in 38 retired Sprague-Dawley rats were created in both hind legs. Each rat had one plug dipped in 2-OCTA before fixation and one control plug. H&E staining was used to quantify bone bridging. The 2-OCTA group had a mean bridging bone circumference of 22.80%, significantly less than 67.75% in the control group (p<0.05). Our data suggests that 2-OCTA blocks bridging bone formation, making it a poor choice for fracture fixation.

Abstract
Data sourcesElectronic search of Medline, Embase, Scopus and the Cochrane Central Register of Controlled Trials (CENTRAL). Manual search of multiple dental journals and review reference lists.Study selectionTwo authors searched studies without any language or follow-up duration restrictions. Randomised and controlled clinical trials with a minimum of five patients per group and a parallel or split-mouth design were included. Outcome variables assessed comparing APC use included: patient satisfaction, self-reported postoperative quality of life, radiographic bone healing, clinical and radiographic marginal bone remodelling, soft tissue healing and complications such as alveolar osteitis.Data extraction and synthesisMethodologic quality of research was assessed using the following parameters: random sequence generation method and allocation concealment, calibration and binding of outcome assessment, comparability of control and treatment groups at entry, clear definition of inclusion and exclusion criteria, clear definition of outcomes assessment and success criteria, completeness of the outcome data reported and explanation for dropouts/withdrawal, recall rate, sample size and number of surgeons involved. Meta-analysis was carried out with data from studies reporting the same outcome measurements at comparable observations times following tooth extraction. Dichotomous outcomes (ie development of alveolar osteitis) for different treatments were expressed as risk ratios with a 95% confidence interval and continuous outcomes (ie quantifiable bone changes) were expressed as mean differences with a 95% confidence interval. Study design risk of bias was assessed using sensitivity analysis.ResultsThirty three studies met the inclusion criteria. Soft tissue healing at seven days after extraction was better when APCs were used (mean difference of 1.01; 95% CI; 0.77 to 1.24). Three months postoperatively, the second mandibular molar distal probing depth was statistically better in the APC group, mean difference of -1.63; (95% CI; -2.05 to -1.22). There were no statistical differences between the APC and control groups for alveolar osteitis, acute inflammation or alveolar infection. Although the percentage of new bone and indirect measurement of bone metabolism were similar for both groups, bone density was statistically better for the APC group, mean difference of 5.06; (95% CI; 1.45 to 8.66). Qualitative analysis found decreased swelling in four of five studies and decreased trismus in two of three studies. The variations between different types of APCs were not evaluated as part of this review.ConclusionsAPCs including platelet-rich plasma (PRP), platelet-rich fibrin (PRF) and plasma rich in growth factors (PRGF) can be used following tooth extraction to improve soft tissue healing, probing depth and bone density, as well as to reduce swelling and trismus. However, their use in reducing other postoperative complications such as pain, alveolar osteitis, inflammation, infection, or in improving new bone percentage and metabolism cannot be recommended. Study heterogeneity made it impossible to perform meta-analysis for pain reduction; therefore further studies investigating the effect on pain are required.

Abstract
BACKGROUND We investigated the clinical effectiveness of antimicrobial prophylaxis in lower-extremity open fractures following the Eastern Association for the Surgery of Trauma Guidelines. METHODS This observational, retrospective, single-center study included adults with lower-extremity open fractures of the ankle, tibia, fibula, or femur. The primary endpoint was the incidence of osteomyelitis within 12 months of the fracture. Secondary endpoint comparisons were the time of antibiotic initiation and drug selection. RESULTS A total of 90 patients were included. Patients suffered from Gustilo and Anderson grades I (14%), II (54.7%), and III (31.3%) fractures. Almost all patients received cefazolin (98%). Among grade III fractures, 59.3% (16/27) of patients received additional gram-negative coverage as recommended by the guidelines. The osteomyelitis rate was 8.9%. There was no difference in osteomyelitis rates among patients with grade III fractures who received or did not receive additional gram-negative coverage: 18.8% (3/16) and 0 (0/11) (p = 0.248), respectively. There was no correlation between median antibiotic start time or antibiotic stop time after closure and the development of osteomyelitis, respectively. Resistant organisms caused 50% (4/8) of the osteomyelitis cases. On univariate analysis, obesity had the most significant association with osteomyelitis (p = 0.026). CONCLUSIONS Bacterial resistance was common among cases of osteomyelitis in our cohort. Obesity was associated with a higher rate of osteomyelitis.

Abstract
Background It is recommended that children aged 3 months to five years of age living in areas of seasonal transmission in the sub-Sahel should receive Seasonal Malaria Chemoprevention (SMC) with sulfadoxine-pyrimethamine plus amodiaquine (SPAQ) during the malaria transmission season. The purpose of this study was to evaluate the safety of SMC with SPAQ in children when delivered by community health workers in three districts in Senegal where SMC was introduced over three years, in children from 3 months of age to five years of age in the first year, then in children up to 10 years of age. Methods A surveillance system was established to record all deaths and all malaria cases diagnosed at health facilities and a pharmacovigilance system was established to detect adverse drug reactions. Health posts were randomized to introduce SMC in a stepped wedge design. SMC with SPAQ was administered once per month from September to November, by nine health-posts in 2008, by 27 in 2009 and by 45 in 2010. Results After three years, 780,000 documented courses of SMC had been administered. High coverage was achieved. No serious adverse events attributable to the intervention were detected, despite a high level of surveillance. Conclusions SMC is being implemented in countries of the sub-Sahel for children under 5 years of age, but in some areas the age distribution of cases of malaria may justify extending this age limit, as has been done in Senegal. Our results show that SMC is well tolerated in children under five and in older children. However, pharmacovigilance should be maintained where SMC is implemented and provision for strengthening national pharmacovigilance systems should be included in plans for SMC implementation.

Abstract
Upregulation of the immune response may be involved in the pathogenesis of schizophrenia with changes occurring in both peripheral blood and brain tissue. To date, microarray technology has provided a limited view of specific inflammatory transcripts in brain perhaps due to sensitivity issues. Here we used SOLiD Next Generation Sequencing to quantify neuroimmune mRNA expression levels in the dorsolateral prefrontal cortex of 20 individuals with schizophrenia and their matched controls. We detected 798 differentially regulated transcripts present in people with schizophrenia compared with controls. Ingenuity pathway analysis identified the inflammatory response as a key change. Using quantitative real-time PCR we confirmed the changes in candidate cytokines and immune modulators, including interleukin (IL)-6, IL-8, IL-1β and SERPINA3. The density of major histocompatibility complex-II-positive cells morphologically resembling microglia was significantly increased in schizophrenia and correlated with IL-1β expression. A group of individuals, most of whom had schizophrenia, were found to have increased inflammatory mRNA expression. In summary, we have demonstrated changes in an inflammatory response pathway that are present in ∼40% of people diagnosed with schizophrenia. This suggests that therapies aimed at immune system attenuation in schizophrenia may be of direct benefit in the brain.

Abstract
Functional genomics, including analysis of the transcriptome and proteome, provides new opportunities for understanding the molecular processes in muscle and how these influence its conversion to meat. The Quality Pork Genes project was established to identify genes associated with variation in different aspects of raw material (muscle) quality and to then develop genetic tools that could be utilized to improve this quality. DNA polymorphisms identified in the porcine PRKAG3 and CAST genes illustrate the impact that such tools can have in improving meat quality. The resources developed in Quality Pork Genes provide the basis for identifying more of these tools.

Abstract
BACKGROUND Marked increases in Clostridium difficile infection (CDI) incidence, driven by epidemic strain spread, is a global phenomenon. METHODS The Clostridium difficile Ribotyping Network (CDRN) was established in 2007 as part of enhanced CDI surveillance in England, to facilitate the recognition and control of epidemic strains. We report on changes in CDI epidemiology in England in the first 3 years of CDRN. RESULTS CDRN received 12,603 fecal specimens, comprising significantly (P < .05) increasing numbers and proportions of national CDI cases in 2007-2008 (n = 2109, 3.8%), 2008-2009 (n = 4774, 13.2%), and 2009-2010 (n = 5720, 22.3%). The C. difficile recovery rate was 90%, yielding 11,294 isolates for ribotyping. Rates of 9 of the 10 most common ribotypes changed significantly (P < .05) during 2007-2010. Clostridium difficile ribotype 027 predominated, but decreased markedly from 55% to 36% and 21% in 2007-2008, 2008-2009, and 2009-2010, respectively. The largest regional variations in prevalence occurred for ribotypes 027, 002, 015, and 078. Cephalosporin and fluoroquinolone use in CDI cases was reported significantly (P < .05) less frequently during 2007-2010. Mortality data were subject to potential reporting bias, but there was a significant decrease in CDI-associated deaths during 2007-2010, which may have been due to multiple factors, including reduced prevalence of ribotype 027. CONCLUSIONS Access to C. difficile ribotyping was associated with significant changes in the prevalence of epidemic strains, especially ribotype 027. These changes coincided with markedly reduced CDI incidence and related mortality in England. CDI control programs should include prospective access to C. difficile typing and analysis of risk factors for CDI and outcomes.

Abstract
BACKGROUND The Apc(Min/+) mouse, an animal model of colorectal cancer and cachexia, has a heterologous mutation in the Apc tumor suppressor gene, predisposing the mouse to intestinal and colon tumor development. This mouse develops intestinal polyps by ~4 weeks of age, and loses body weight gradually between ~14 and ~20 weeks of age. The strengths of this cachexia model derive from several features that mimic human cancer, including a gradual increase in tumor burden, chronic inflammation, and anemia. Little is known about the role of gut barrier dysfunction and endotoxemia in the development of cancer cachexia. We sought to determine how gut permeability and resultant endotoxemia change with the progression of cachexia. METHODS Intestinal gut barrier integrity was assessed by permeability to FITC-dextran (MW(av)=4000kDa; FD4). Plasma glucose and triglycerides were measured by enzymatic assays, IL-6 by enzyme-linked immunosorbent assay, and endotoxin by the limulus amoebocyte assay. Body temperature was measured using a rectal probe. RESULTS Progression of cachexia was accompanied by development of gut barrier dysfunction (permeability to FD4), hypertrophy of mesenteric lymph nodes, and an increase in plasma endotoxin concentration. Changes in blood glucose and glucose tolerance, plasma IL-6, triglycerides, and body temperature were characteristic of endotoxemia. CONCLUSION We propose a role for gut barrier dysfunction (GBD) and subsequent endotoxemia in the development of inflammation and progression of cachexia in the Apc(Min/+) mouse.

Abstract
The psychologic and psychosexual sequelae of cervical screening and disease are well recognized but most research has focused on women with cervical intraepithelial neoplasia (CIN) or women with early (stage IB) to advanced cervical cancer. There has been little work looking at women with microinvasive cancer as a unique clinical identity. Many of these women have a similar diagnostic, treatment, and follow-up pathway to those with high-grade CIN. This could result in unrecognized and ongoing health concerns. We report on a questionnaire-based case-control study, comparing the concerns of women with microinvasive cervical cancer with those of women with high-grade CIN. Women with microinvasive cancer and controls with CIN2/3 diagnosed between 2000 and 2006, from a geographically defined population, were recruited and invited to complete a postal questionnaire consisting of the Hospital Anxiety and Depression Scale (HADS) and the Process Outcome Specific Measure (POSM). Twenty-eight women diagnosed with microinvasive cancer were identified and 18 participated (response rate 64%). Fifty-eight controls were matched by age and year of treatment with 26 responding (45%). About 18% of women with microinvasive cancer had a HADS depression score of 8 or more, compared to 12% of those with CIN (P = not significant). The HADS anxiety score of 8 or more occurred in 35% of each group. There were no significant differences in terms of POSM results for sexual activity, fertility, and developing cervical cancer in the future between cases and controls. We did not find a difference between women with a previous diagnosis of microinvasive cancer and those with high-grade CIN, in terms of ongoing concerns during their follow-up. We did not identify any additional concerns for women with microinvasive cancer in the care provided in the colposcopy service.

Abstract
BACKGROUND This study examines the importance of staff judgements of responsibility for challenging behaviour in predicting their emotional and intended helping responses. METHODS Sixty-two carers completed questionnaires rating attributions of internality, stability and controllability, emotions of sympathy and anger, judgements of responsibility for the development of challenging behaviour and for its resolution and intended effort in helping in response to a scenario describing an aggressive behaviour. RESULTS Results showed significant correlations between judgements of responsibility and attributions, emotions and intended effort in helping. Regression analysis showed that the best predictor of intended helping is the emotion of sympathy and that sympathy is best predicted by the attribution of internality, the judgement that people are not responsible for the development of challenging behaviour and the judgement that they are responsible for the resolution of the behaviour. CONCLUSIONS Judgements of responsibility predict emotional and intended behavioural responses of carers of people with intellectual disabilities and challenging behaviour. The results are discussed in relation to previous work on carer attributions in response to challenging behaviour. Implications for clinical work with carers are considered.

Abstract
OBJECTIVES To determine if cervical length obtained with three-dimensional ultrasound correlated with the 'true cervical volume' and to evaluate the reliability and validity of transabdominal and transvaginal three-dimensional cervical volume measurement. METHODS This was a prospective observational study. Three-dimensional cervical volume measurements were made prior to hysterectomy in 28 women. Following hysterectomy the amputated cervical volume was calculated using water displacement. For the assessment of intra- and interobserver reliability, the intraclass correlation coefficient (ICC) was used. The index of concordance between the sonographic cervical volumes and those obtained by the reference standard (true cervical volume) was assessed with the limits of agreement method and the ICC. RESULTS Transabdominal cervical length and transvaginal cervical length correlated moderately with actual cervical volume; correlation coefficients were 0.64 and 0.57 (P < 0.05), respectively. Intraobserver reliability for both transabdominal and transvaginal cervical volume assessment was good (> 0.75). Interobserver reliability for transvaginal cervical volumes was similarly good (ICC = 0.90). However, for transabdominal measurements the interobserver reliability was poor (ICC = 0.51). The validity of both methods of three-dimensional volume assessment was poor (ICC < 0.75). This was reflected in the wide limits of agreement, which ranged from approximately - 25 mL to + 30 mL. CONCLUSION The reliability and validity of three-dimensional cervical volume measurement are poor. Clinical introduction of cervical volume measurement should be avoided at this time.

Abstract
There is little information outlining the role of Rho kinase, RhoA, and calcium sensitization in regulation of human uterine contractility during pregnancy. The aims of this study were to investigate the expression of RhoA, and the Rho kinases ROCK I and ROCK II in human pregnant myometrium, to evaluate the effects of Rho kinase inhibition on pregnant human myometrial contractility in vitro, and to compare these effects with those of the calcium channel blocker nifedipine. RT-PCR using primers for RhoA, ROCK I and ROCK II was performed on mRNA isolated from human pregnant myometrium. Isometric recording was performed in isolated myometrial strips obtained at Caesarean section. The effects of the Rho kinase inhibitor Y-27632 (1 nmol/l to 10 mmol/l), and nifedipine (1 nmol/l to 10 mmol/l), on oxytocin (0.5 nmol/l) induced contractions were measured and compared. Expression of RhoA, ROCK I and ROCK II mRNA was identified in human pregnant myometrium (n = 3). Y-27632 exerted a potent relaxant effect on myometrial contractility with a pD(2) value (+/- SEM) of 7.63 +/- 0.38 (n = 6). The maximum net relaxant effect (+/- SEM) was 72.3 +/- 6.1% (n = 6). Corresponding values for nifedipine were 7.24 +/- 0.48 (n = 6; P = 0.469) and 93.40 +/- 3.1% (n = 6; P = 0.028). Rho A/Rho kinase-mediated calcium sensitization may play role in the physiology of human parturition, and pharmacological inhibition of this pathway may therefore provide a novel approach to tocolysis for pre-term labour.

Abstract
The G-protein activators guanosine 5'-O-(3-thiodiphosphate) (GTP gamma S) and aluminum fluoride (AIF) are thought to inhibit transport between Golgi cisternae by causing the accumulation of nonfunctional coatomer-coated transport vesicles on the Golgi. Although GTP gamma S and AIF inhibit transport in cell-free intra-Golgi transport systems, blocking coatomer vesicle formation does not. We therefore determined whether inhibition of in vitro Golgi transport by these agents requires coatomer vesicle formation. Depletion of coatomer was found to completely block coated vesicle formation on Golgi cisternae without affecting inhibition of in vitro transport by either GTP gamma S or AIF. Depletion of ADP-ribosylation factor (ARF) prevented inhibition of transport by GTP gamma S, but not by AIF, suggesting that the AIF-sensitive component in transport may not be a GTP-binding protein. Surprisingly, depletion of cytosolic ARF did not prevent the GTP gamma S-induced formation of Golgi-coated vesicles, whereas ARF was required for AIF-induced vesicle formation. Although ARF or coatomer depletion caused an increase in the fenestration of cisternae, no other ultrastructural changes were observed that might explain the inhibition of transport by GTP gamma S or AIF. These findings suggest that ARF-GTP gamma S and AIF act by distinct and coatomer-independent mechanisms to inhibit membrane fusion in cell-free intra-Golgi transport.

Abstract
We have prospectively studied the influence of a nurse practitioner service on out of hours work intensity of surgical house officers. Data collection was achieved by prospective audit. The study was set in the surgical wards in a large teaching hospital. The main outcome measures were; 1) the nature and frequency of overnight calls to the nurse practitioner, and 2) the outcome of these calls (doctor not bleeped, telephone advice given by doctor or doctor attended ward). A total of 645 calls were made over the 75 night study period (8.6 calls/night). Two hundred and ninety-six calls were managed by the nurse practitioner alone. This represents a 46% reduction in work intensity for the surgical house officer. This study illustrates the benefits of a nurse practitioner service and also identifies important areas for undergraduate education in preparing medical students for the common problems encountered during the surgical on-call period.

Abstract
This study examined associations between a vitamin E-deficient diet, ageing and aspects of the morphology of neuronal lipopigment in rat hippocampal and Purkinje neurones. Groups of rats given a standard diet were killed at 6, 12, 18 and 25 months of age, while a group which had received a vitamin E-deficient diet from 1-18 months were killed at 18 months of age. Lipopigment within a neuronal cell body consists of a number of discrete regions of varying size. These were identified by fluorescence microscopy and a photograph for each individual neurone was projected onto paper, so that the outlines of the discrete regions of lipopigment could be drawn and subjected to morphometric measurements. Both ageing and vitamin E deficiency in relation to hippocampal neurones and vitamin E deficiency in relation to Purkinje neurones (in which ageing effects were not examined), were associated with a significant (< 0.05) increase in the mean total area (per rat) enclosed by the lipopigment outlines. For both vitamin E deficiency and ageing this increase was associated with both an increase in the number of relatively large discrete lipopigment regions and a decrease in the number of relatively small discrete lipopigment regions. The findings in relation to vitamin E deficiency could be explained by an increased rate of lipopigment formation, involving processes which also occur in ageing.
