Gaal A, Shimchuk A, Gray S, Bloomquist D, Dillon J. Are postoperative antibiotics required after orthognathic surgery? Int J Oral Maxillofac Surg 2023; 52:211-218. [PMID: 35780069 DOI: 10.1016/j.ijom.2022.06.007] [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: 06/20/2021] [Revised: 06/15/2022] [Accepted: 06/20/2022] [Indexed: 01/11/2023]
Abstract
The aim of this study was to investigate and compare the frequency of surgical site infection (SSI) between orthognathic patients who received only intraoperative antibiotics and patients who received intraoperative antibiotics plus postoperative antibiotics. A retrospective study was performed of patients treated by a single surgeon over the years 2006-2012 and 2016-2019. The primary predictor variable was antibiotic exposure. The control group received no postoperative prophylactic antibiotics. The study group received postoperative antibiotics. Both groups received prophylactic intraoperative antibiotics and performed postoperative chlorhexidine rinses. The primary outcome was SSI frequency. Univariate, bivariate, and multiple logistic regression analyses were performed; statistical significance was set at P ≤ 0.05. The sample comprised 333 patients. Their mean age was 30.7 ± 11.8 years. The study group included 129 patients (38.7%); the control group included 204 patients (61.3%). The frequency of SSI was 17.1% in the study group and 26.5% in the control group (P = 0.048). In the multivariable logistic regression, only alcohol consumption was significantly associated with an increased risk of SSI (odds ratio 2.46, 95% confidence interval 1.36-4.44; P = 0.003). In patients undergoing orthognathic surgery, postoperative antibiotic exposure in addition to intraoperative prophylaxis approached but was not statistically significant for a decreased risk of SSI (P = 0.067).

Abstract
Background Scotland first demonstrated that adherence to nationally agreed hip fracture standards improve patient survival, reduces the duration of admission, and reduces the need for high dependency care. Our study aims to assess adherence to the Irish Hip Fracture Standards (IHFS) in our hospital for 2021 amidst the COVID-19 pandemic, translating to improved clinical outcomes for our patients. Methods The IHF database was retrospectively analysed, comparing quarters 1-4 in 2021 with our 2020 results. Results IHFS1, patient time to the ward < 4hours, was maintained at 67% in 2021 versus 71% overall in 2020. There was improvement in IHFS2, time to surgery within 48 hours, up to 73% in 2021 versus 66% in 2020. IHFS3 was 4% in 2021 versus 3% overall in 2020. Further improvements were noted for IHFS4, with 95% of patients reviewed by a Geriatrician in 2021 versus 87% in 2020. IHFS5 also improved with 97% of patients receiving a bone health assessment in 2021 versus 87% in 2020. Moreover, IHFS6, improved with 97% of patients undergoing a specialised falls assessment in 2021 versus 87% in 2020. Conclusion The improvement in 2021 figures is reflective of the return of redeployed services during the COVID-19 pandemic inclusive of the Orthogeriatric Service, the Fracture Liaison Service Advanced Nurse Practitioner, the Trauma Co-ordinator, and the specialist Orthopaedic ward complete with its Orthopaedic nurses and Multi-Disciplinary Team, and improved Emergency Department pathways. These continued improvements in the IHFS further emphasise that success is dependent on a team that is joined at the hip

Abstract
Abstract
Background
Nationally agreed hip fracture standards have contributed to the improvement of outcomes in hip fracture patients. In 2020, our hospital was awarded “The Golden Hip” for achieving highest compliance with Irish Hip Fracture Standards (IHFS) nationally for 2019.
Methods
Data from the Irish Hip Fracture Database (IHFD)was retrospectively analysed to assess our performance in 2020 versus 2019 in hip fracture patients over sixty. Multiple quality improvement interventions were put in place throughout 2019 to ensure improvement in IHFS1-6 compliance: Creation of the Hip Fracture Pathway Subgroup, IHFS 1 Breaches Audit, Orthogeriatric input at Orthopaedic inductions, weekly Multi-disciplinary Team meetings, a Nutritional Hip Fracture Pathway and addition of the Fracture Liaison Service Advanced Nurse Practitioner.
Results
There were 239 hip fracture patients in 2020 vs 249 in 2019. IHFS1 compliance improved with the percentage of patients admitted to the Orthopaedic ward within 4 hours increasing to 71% in 2020 from 56% in 2019. There was improvement in IHFS2-time to surgery <48 hours- 66% in 2020 vs 60% in 2019. IHFS3-pressure ulcer rate-was at the national average, 3% in 2020 vs 2% in 2019. IHFS4 (reviewed by a Geriatrician), IHFS5 (received a bone health assessment) and IHFS6 (received a specialised falls assessment) were lower overall; 87% in 2020 vs 98% in 2019. For all quarters (Q),43% of patients met all IHFS in our hospital in 2020 vs 32% in 2019, resulting in €90,000 in Best Practice Tariff funding.
Conclusion
Lower results for IHFS 4,5 and 6 reflect the arrival of the COVID-19 pandemic which led to redeployment of the Orthogeriatric Service and redeployment of the MDT from end of Q1 to Q3. When services in 2020 were preserved,1 in 2 hip fracture patients met all IHFS, vs 1 in 3 patients in 2019. Despite the pandemic, we continued to achieve the highest level of IHFS compliance nationally, being awarded a second consecutive “Golden Hip” for 2020.

Abstract
BACKGROUND This study assesses whether increased coverage of the measles, mumps and rubella (MMR) vaccination differs between areas where school nurses deliver catch-up MMR doses to adolescents in school settings, compared to signposting to general practice. METHODS A retrospective cohort study was conducted using Child Health Information Services records within the NHS England South (South Central) commissioning boundary. The sample population included children born 1 September 2000-31 August 2001, in school year 9 during the 2014-15 academic year. RESULTS The primary outcome findings show an increase in coverage of at least one dose of MMR by 1.6% (n = 334) in the cohort receiving catch-up MMR, compared to 0.2% (n = 12) in the cohort signposted to general practice. Over time, the difference in increase between the two cohorts was 1.4%, analysed using the chi-squared comparison of proportions test, providing strong evidence (P < 0.0001) that school nurse delivery of catch-up MMR is effective at increasing coverage. The findings also suggest that school nurse delivery of catch-up MMR may benefit Black, Asian and minority ethnic children and those from more deprived backgrounds. CONCLUSIONS It is recommended that commissioners of school-aged immunization services incorporate the delivery of catch-up MMR doses in their contracts with school nurses.

Abstract
Abstract
Background
Lipoprotein (a) (Lp(a)) measurement may help guide CVD risk prediction, is thought to be causal in several CVD outcomes, and phase 3 intervention trials of Lp(a) lowering agents are underway. We aimed to investigate the population attributable fraction due to elevated Lp(a) and its utility in CVD risk prediction.
Methods
In 413,724 participants from UK Biobank, associations of serum Lp(a) with composite fatal/nonfatal CVD (n=10,065 events), fatal CVD (n=3247), coronary heart disease (n=16,649), ischaemic stroke (n=3191), and peripheral vascular disease (n=2716) were compared using Cox models. Predictive utility was determined by C-index changes. The population attributable fraction was estimated.
Results
Median Lp(a) was 19.7nmol/L (interquartile interval 7.6–75.3nmol/L). 20.8% had Lp(a) values >100nmol/L; 9.2% had values >175nmol/L. After adjustment for classical risk factors, in participants with no baseline CVD and not taking a statin, 1 standard deviation increment in log Lp(a) was associated with a HR for fatal/nonfatal CVD of 1.09 (95% CI 1.07–1.11). Associations were similar for fatal CVD, coronary heart disease, and peripheral vascular disease. Adding Lp(a) to a prediction model containing traditional CVD risk factors improved the C-index by +0.0017 (95% CI 0.0009, 0.0026). We estimated that having Lp(a) values >100nmol/L accounts for 5.7% of CVD events in the whole cohort. We modelled that an ongoing trial to lower Lp(a) in patients with CVD and Lp(a) above ∼175nmol/L may be expected to reduce CVD risk by 20.3%, assuming causality, and an achieved Lp(a) reduction of 80%.
Conclusions
Population screening for elevated Lp(a) may help to predict CVD and target Lp(a) lowering drugs to those with markedly elevated levels, if such drugs prove efficacious.
Population attributable fractions: Lp(a)

Abstract
The purpose of this study was to validate the appropriateness of the Comprehensive Vocational Evaluation System (CVES) for evaluating the work potential and independent living levels of visually impaired and blind individuals. The CVES was administered to 237 clients of the Texas Commission for the Blind (TCB), and the results were used to predict the vocational placement and independent living levels of these clients as determined by the TCB staff. The results indicated that the CVES is significantly related to work and independent living outcomes for visually impaired and blind people.

Abstract
Hypertension is a risk factor for cardiovascular disease. Increased urinary sodium excretion, representing dietary sodium intake, is associated with hypertension. Low sodium intake has been associated with increased mortality in observational studies. Further studies should assess whether confounding relationships explain associations between sodium intake and outcomes. We studied UK Biobank participants (n=457 484; mean age, 56.3 years; 44.7% men) with urinary electrolytes and blood pressure data. Estimated daily urinary sodium excretion was calculated using Kawasaki formulae. We analyzed associations between sodium excretion and blood pressure in subjects without cardiovascular disease, treated hypertension, or diabetes mellitus at baseline (n=322 624). We tested relationships between sodium excretion, incidence of fatal and nonfatal cardiovascular disease, heart failure, and mortality. Subjects in higher quintiles of sodium excretion were younger, with more men and higher body mass index. There was a linear relationship between increasing urinary sodium excretion and blood pressure. During median follow-up of 6.99 years, there were 11 932 deaths (1125 cardiovascular deaths) with 10 717 nonfatal cardiovascular events. There was no relationship between quintile of sodium excretion and outcomes. These relationships were unchanged after adjustment for comorbidity or excluding subjects with events during the first 2 years follow-up. No differing risk of incident heart failure (1174 events) existed across sodium excretion quintiles. Urinary sodium excretion correlates with elevated blood pressure in subjects at low cardiovascular risk. No pattern of increased cardiovascular disease, heart failure, or mortality risk was demonstrated with either high or low sodium intake.

Abstract
Abstract
Background
Controversies exist about the relationship between body habitus and mortality, especially for patients with cardiovascular disease.
Purpose
We evaluated the relations between different anthropometric indices and mortality amongst participants with and without cardiovascular (CV) risk factors, or established CV disease (stroke, myocardial infarction and/or heart failure), enrolled in the UK Biobank.
Methods
The UK Biobank is a large prospective study which, between 2006 and 2010, enrolled 502,620 participants aged 38–73 years. Participants filled questionnaires and had a medical history recorded, physical measurements done and biological samples taken. The UK Biobank is routinely linked to national death registries and updated on a quarterly basis. Data on death were coded according to the International Classification of Diseases, 10th Revision (ICD-10). The primary end-point was all-cause mortality (ACM) across three subgroups of men and women: those with, or without, one or more CV risk factors (smoking, diabetes and/or hypertension), and those with CV disease (history of stroke, myocardial infarction and/or heart failure) at recruitment. Presence, or absence, of CV risk factors and diagnoses of CV disease were self-reported by participants at enrolment. Associations between anthropometric indices (body mass index (BMI), waist circumference (WC), waist to hip ratio (WHiR), and waist to height ratio (WHeR)) and the risk of all-cause mortality were analysed using Cox regression models.
Results
After excluding those with history of cancer at baseline (n=45,222), 453,046 participants were included (median age: 58 (interquartile range: 50 - 63) years; 53% women), of whom 150,732 had at least one CV risk factor, and 17,884 established CV disease.
During a median follow-up of 5 years, 6,319 participants died. Baseline BMI had a U-shaped relationship with ACM, with higher nadir-values for those with CV risk factors or CV disease, for both sexes (figure). WC, WHiR and WHeR (measures of central distribution of body fat) had more linear associations with ACM, regardless of CV risk factors, CV disease and sex.
Conclusions
For adults with or without CV risk factors or established CV disease, measures of central distribution of body fat are more strongly and more linearly associated with ACM than BMI. WC, or WHiR, rather than BMI, appear to be more appropriate variables for risk stratification.

Abstract
Abstract
Background
Endurance trained athletic healthy volunteers (Athl-HV) and type 2 diabetes patients (T2D) have higher levels of lipids in their skeletal myocytes compared to healthy controls. Despite apparently similar metabolic storage, they are at opposite ends of insulin sensitivity and cardio-metabolic risk.
Purpose
We investigated if the degree of saturation of the IntraMyoCellular Lipids (IMCL) will differentiate Athl-HV from T2D; and explored if an exercise intervention will induce changes in the IMCL saturation.
Methods
Male, age matched Athl-HV and T2D were enrolled (n=25/group). Athl-HV had ≥5 years endurance training, T2D were sedentary. Subjects were studied at baseline and after an exercise intervention (4 week deconditioning in Athl-HV and supervised bike training at ≥65% of peakVO2, 5 hours/week x 8 weeks in T2D). All subjects underwent cardio-pulmonary exercise testing (CPET), blood sampling for insulin sensitivity (QUICKI*) and single voxel 1H-magnetic resonance spectroscopy (1H-MRS) of the right vastus lateralis. 1H-MRS was acquired on 3T Philips Achieva with a 16-channel coil, point-resolved spectroscopy, variable pulse power and optimized relaxation delay water suppression and analysed in LCModel. We derived fractional lipid mass (fLM) and fractions of saturated (fSL) and unsaturated (fUL) lipids. Data were analysed by t tests, shown as mean±SEM, statistical significance p<0.05.
Results
CPET and insulin sensitivity are presented in Table 1. T2D had higher fLM in the skeletal muscle compared to Athl-HV, at baseline (p=0.003) and after the exercise intervention (p=0.009), Figure 1A. At baseline, T2D had a different phenotype with a lower fSL and higher fUL compared to Athl-HV (82±3 vs 88±1% and 18±3 vs 12±1%, p=0.02 for both). Whilst deconditioning did not attract any significant changes in either fSL or fUL in Athl-HV (88±1 to 86±1% and 12±1 to 14±1, p=0.2), in contrast, with exercise training T2D significantly increased fSL (82±3 to 88±1%) and decreased their fUL (18±3 to 12±1%) (both p=0.01). Figure 1B and 1C.

Conclusion
We demonstrate for the first time, in vivo, significant differences in the IMCL amount and saturation between Athl-HV and T2D. IMCL saturation was changed by exercise training in T2D to mirror the phenotype seen in Athl-HV uncovering a new, independent biomarker of improved cardio-metabolic health.

Abstract
The annual Eastern Canadian Gastrointestinal Cancer Consensus Conference was held in Halifax, Nova Scotia, 20-22 September 2018. Experts in radiation oncology, medical oncology, surgical oncology, and pathology who are involved in the management of patients with gastrointestinal malignancies participated in presentations and discussion sessions for the purpose of developing the recommendations presented here. This consensus statement addresses multiple topics in the management of pancreatic cancer, pancreatic neuroendocrine tumours, hepatocellular cancer, and rectal and colon cancer, including ■ surgical management of pancreatic adenocarcinoma,■ adjuvant and metastatic systemic therapy options in pancreatic adenocarcinoma,■ the role of radiotherapy in the management of pancreatic adenocarcinoma,■ systemic therapy in pancreatic neuroendocrine tumours,■ updates in systemic therapy for patients with advanced hepatocellular carcinoma,■ optimum duration of adjuvant systemic therapy for colorectal cancer, and■ sequence of therapy in oligometastatic colorectal cancer.
