Improving oral health and related health behaviours (substance use, smoking, diet) in people with severe and multiple disadvantage: A systematic review of effectiveness and cost-effectiveness of interventions.

BACKGROUND: People experiencing homelessness co-occurring with substance use or offending ('severe and multiple disadvantage' SMD) often have high levels of poor oral health and related health behaviours (particularly, substance use, smoking, poor diet). This systematic review aimed to assess the effectiveness and cost-effectiveness of interventions in adults experiencing SMD to improve oral health and related health behaviours. METHODS AND FINDINGS: From inception to February 2023, five bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, and Scopus) and grey literature were searched. Two researchers independently screened the search results. Randomized controlled trials (RCTs), comparative studies and economic evaluations were included that reported outcomes on oral health and the related health behaviours. Risk of bias was assessed and results narratively synthesized. Meta-analyses were performed where appropriate. This review was registered with PROSPERO (reg. no: CRD42020202416). Thirty-eight studies were included (published between 1991 and 2023) with 34 studies reporting about effectiveness. Most studies reported on substance use (n = 30). Interventions with a combination of housing support with substance use and mental health support such as contingent work therapy appeared to show some reduction in substance use in SMD groups. However, meta-analyses showed no statistically significant results. Most studies had short periods of follow-up and high attrition rates. Only one study reported on oral health; none reported on diet. Three RCTs reported on smoking, of which one comprising nicotine replacement with contingency management showed improved smoking abstinence at 4 weeks compared to control. Five studies with economic evaluations provided some evidence that interventions such as Housing First and enhanced support could be cost-effective in reducing substance use. CONCLUSION: This review found that services such as housing combined with other healthcare services could be effective in improving health behaviours, particularly substance use, among SMD groups. Gaps in evidence also remain on oral health improvement, smoking, and diet. High quality studies on effectiveness with adequate power and retention are needed to address these significant health challenges in SMD populations.

Alternative cascade-testing protocols for identifying and managing patients with familial hypercholesterolaemia: systematic reviews, qualitative study and cost-effectiveness analysis.

Background: Cascade testing the relatives of people with familial hypercholesterolaemia is an efficient approach to identifying familial hypercholesterolaemia. The cascade-testing protocol starts with identifying an index patient with familial hypercholesterolaemia, followed by one of three approaches to contact other relatives: indirect approach, whereby index patients contact their relatives; direct approach, whereby the specialist contacts the relatives; or a combination of both direct and indirect approaches. However, it is unclear which protocol may be most effective. Objectives: The objectives were to determine the yield of cases from different cascade-testing protocols, treatment patterns, and short- and long-term outcomes for people with familial hypercholesterolaemia; to evaluate the cost-effectiveness of alternative protocols for familial hypercholesterolaemia cascade testing; and to qualitatively assess the acceptability of different cascade-testing protocols to individuals and families with familial hypercholesterolaemia, and to health-care providers. Design and methods: This study comprised systematic reviews and analysis of three data sets: PASS (PASS Software, Rijswijk, the Netherlands) hospital familial hypercholesterolaemia databases, the Clinical Practice Research Datalink (CPRD)-Hospital Episode Statistics (HES) linked primary-secondary care data set, and a specialist familial hypercholesterolaemia register. Cost-effectiveness modelling, incorporating preceding analyses, was undertaken. Acceptability was examined in interviews with patients, relatives and health-care professionals. Result: Systematic review of protocols: based on data from 4 of the 24 studies, the combined approach led to a slightly higher yield of relatives tested [40%, 95% confidence interval (CI) 37% to 42%] than the direct (33%, 95% CI 28% to 39%) or indirect approaches alone (34%, 95% CI 30% to 37%). The PASS databases identified that those contacted directly were more likely to complete cascade testing (p < 0.01); the CPRD-HES data set indicated that 70% did not achieve target treatment levels, and demonstrated increased cardiovascular disease risk among these individuals, compared with controls (hazard ratio 9.14, 95% CI 8.55 to 9.76). The specialist familial hypercholesterolaemia register confirmed excessive cardiovascular morbidity (standardised morbidity ratio 7.17, 95% CI 6.79 to 7.56). Cost-effectiveness modelling found a net health gain from diagnosis of -0.27 to 2.51 quality-adjusted life-years at the willingness-to-pay threshold of £15,000 per quality-adjusted life-year gained. The cost-effective protocols cascaded from genetically confirmed index cases by contacting first- and second-degree relatives simultaneously and directly. Interviews found a service-led direct-contact approach was more reliable, but combining direct and indirect approaches, guided by index patients and family relationships, may be more acceptable. Limitations: Systematic reviews were not used in the economic analysis, as relevant studies were lacking or of poor quality. As only a proportion of those with primary care-coded familial hypercholesterolaemia are likely to actually have familial hypercholesterolaemia, CPRD analyses are likely to underestimate the true effect. The cost-effectiveness analysis required assumptions related to the long-term cardiovascular disease risk, the effect of treatment on cholesterol and the generalisability of estimates from the data sets. Interview recruitment was limited to white English-speaking participants. Conclusions: Based on limited evidence, most cost-effective cascade-testing protocols, diagnosing most relatives, select index cases by genetic testing, with services directly contacting relatives, and contacting second-degree relatives even if first-degree relatives have not been tested. Combined approaches to contact relatives may be more suitable for some families. Future work: Establish a long-term familial hypercholesterolaemia cohort, measuring cholesterol levels, treatment and cardiovascular outcomes. Conduct a randomised study comparing different approaches to contact relatives. Study registration: This study is registered as PROSPERO CRD42018117445 and CRD42019125775.

Familial hypercholesterolaemia is an inherited condition that causes raised cholesterol levels from birth and increases risk of heart disease if left untreated. After someone in a family is found to have familial hypercholesterolaemia (called an index case), their close relatives need to be contacted and checked to see if they have familial hypercholesterolaemia, using genetic or cholesterol testing. This is called 'cascade testing'. We planned to find the most cost-effective and acceptable way to do this. The relatives could be contacted for testing by the index case (indirect approach), by a health-care professional (direct approach) or by a combination of both approaches. We found, based on looking at hospital records, that more relatives were tested if health-care professionals directly contacted relatives. In previous studies, slightly more relatives were tested for familial hypercholesterolaemia with a combination approach. Interviews with patients also suggested that the direct approach was the most effective, but the most acceptable and successful approach depends on family relationships: using one approach for some families and using both for other families. Furthermore, by looking at the health-care records of large numbers of patients, we confirmed that people with a recorded diagnosis of familial hypercholesterolaemia in general practice records have a much higher risk of heart disease than the general population, and this was especially so for those with previous heart disease and/or raised cholesterols levels when diagnosed. However, one-quarter of new patients with familial hypercholesterolaemia recorded in their records were not treated within 2 years, with less than one-third reaching recommended cholesterol levels. We used what we had learned to help us estimate the most cost-effective way to do cascade testing. This showed that if the health service directly contact all relatives simultaneously for further assessment, rather than the current approach whereby close (first-degree) relatives are contacted first, this was cost-effective and good value for money.

Interventions to improve oral health and related health behaviours of substance use, smoking, and diet in people with severe and multiple disadvantage: a systematic review of effectiveness and cost-effectiveness.

BACKGROUND: Homelessness overlapping with substance use and offending is described as severe and multiple disadvantage (SMD). People experiencing SMD have poor oral health along with high levels of related behaviours such as substance use, smoking, and poor diet. Existing evidence largely describes the prevalence of oral health problems, substance use, and smoking in SMD groups. Little is known about interventions that can address these conditions in SMD groups. We aimed to review the effectiveness and cost-effectiveness of interventions on oral health and related health behaviours in adults experiencing SMD. METHODS: For this systematic review, we searched bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, EBSCO, Scopus) and grey literature for papers published from inception to February 2023. Two researchers independently reviewed the searches. Randomised controlled trials (RCTs), comparative studies and economic evaluations were included. Risk of bias was assessed. Population included adults experiencing SMD (including homelessness and substance use or repeat offending). Outcomes included oral health, and related behaviours (substance use, smoking, poor diet). Results were narratively synthesised. This review was registered with PROSPERO, CRD42020202416. FINDINGS: The review included 38 studies (published between 1991 and 2023), with 34 reporting effectiveness. These studies comprised of 23 RCTs and 11 quasi-experimental studies conducted in the USA (25 studies), Canada (seven studies), France (one study), and Spain (one study). The interventions involving multiple components, such as housing services with substance use and mental health support, effectively reduced substance use in SMD groups; these were mostly individual-level interventions. However, these studies had short follow-up periods and high attrition rates. Only one study addressed oral health outcomes, none focused on diet, and three RCTs covered smoking, with one intervention showing smoking abstinence at 4 weeks. Some limited evidence suggested cost-effectiveness of substance use interventions. INTERPRETATION: This review found that integrating services such as housing with other health-care services together could be effective in improving health behaviours, especially substance use among SMD groups. More evidence is needed specifically on oral health, smoking, and diet-related interventions. The generalisability of findings of this review is limited to high-income countries and shorter-term outcomes.

The performance of FIT-based and other risk prediction models for colorectal neoplasia in symptomatic patients: a systematic review.

Background: Colorectal cancer (CRC) incidence and mortality are increasing internationally. Endoscopy services are under significant pressure with many overwhelmed. Faecal immunochemical testing (FIT) has been advocated to identify a high-risk population of symptomatic patients requiring definitive investigation by colonoscopy. Combining FIT with other factors in a risk prediction model could further improve performance in identifying those requiring investigation most urgently. We systematically reviewed performance of models predicting risk of CRC and/or advanced colorectal polyps (ACP) in symptomatic patients, with a particular focus on those models including FIT. Methods: The review protocol was published on PROSPERO (CRD42022314710). Searches were conducted from database inception to April 2023 in MEDLINE, EMBASE, Cochrane libraries, SCOPUS and CINAHL. Risk of bias of each study was assessed using The Prediction study Risk Of Bias Assessment Tool. A narrative synthesis based on the guidelines for Synthesis Without Meta-Analysis was performed due to study heterogeneity. Findings: We included 62 studies; 23 included FIT (n = 22) or guaiac Faecal Occult Blood Testing (n = 1) combined with one or more other variables. Twenty-one studies were conducted solely in primary care. Generally, prediction models including FIT consistently had good discriminatory ability for CRC/ACP (i.e. AUC >0.8) and performed better than models without FIT although some models without FIT also performed well. However, many studies did not present calibration and internal and external validation were limited. Two studies were rated as low risk of bias; neither model included FIT. Interpretation: Risk prediction models, including and not including FIT, show promise for identifying those most at risk of colorectal neoplasia. Substantial limitations in evidence remain, including heterogeneity, high risk of bias, and lack of external validation. Further evaluation in studies adhering to gold standard methodology, in appropriate populations, is required before widespread adoption in clinical practice.

A COnsensus-based Standards for the selection of health Measurement INstruments systematic review of orthognathic patient-reported outcome measures.

INTRODUCTION: This systematic review aimed to identify and appraise the validity studies of patient-reported outcome measures (PROMs) reporting the outcomes of combined orthodontic-orthognathic surgery in treating dentofacial deformity. METHODS: The search strategy was conducted using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Systematic Review methodology. The following databases were searched for original studies outlining the development and/or validation of PROMs produced to measure the outcomes of combined orthognathic-orthodontic treatment: EMBASE, MEDLINE, PsycInfo and Scopus. Publications were limited to the English language. Eligibility criteria were applied when considering the studies. Primarily, the psychometric properties and quality of orthognathic-specific PROMs were investigated. Screening of eligible studies was conducted independently by 2 reviewers. Assessment of the methodological quality of the studies and data extraction was conducted by 1 reviewer and assisted by a second reviewer. The COSMIN methodology guided data extraction and analysis, which were divided into 3 stages-a synopsis of studies, evaluation of methodological quality, and summary of evidence. RESULTS: A total of 8695 papers were found; 12 studies met the criteria for inclusion. Regarding the COSMIN Checklist for Assessing Study Qualities, there was evidence that the Orthognathic Quality of Life Questionnaire was the most extensively tested orthognathic-specific PROM in the current literature. The reported evidence was incomplete, as not all psychometric properties had been reliably tested. CONCLUSIONS: Clinicians must use validated PROMs when analyzing patient-reported outcomes. The Orthognathic Quality of Life Questionnaire was shown to be the highest quality orthognathic-specific PROM in the literature but requires contemporary evaluation to suitably reflect the COSMIN guidance.

Practitioner and digitally delivered interventions for reducing hazardous and harmful alcohol consumption in people not seeking alcohol treatment: a systematic review and network meta-analysis.

AIM: To compare the effectiveness of practitioner versus digitally delivered interventions for reducing hazardous and harmful alcohol consumption. DESIGN: Systematic review and network meta-analysis comprising comprehensive search for randomised controlled trials, robust screening and selection methods and appraisal with the Cochrane Risk of Bias tool. Network meta-analyses were conducted in Stata using random effects, frequentist models. The confidence in network meta-analysis (CINeMA) tool was used to assess confidence in effect sizes. SETTING: Online or community or health settings where the intervention was immediately accessible without referral. PARTICIPANTS: Non treatment-seeking hazardous or harmful drinkers. MEASUREMENTS: Primary outcome was mean difference in alcohol consumption (g/wk); secondary outcome was number of single high intensity drinking episodes. Baseline consumption was analysed as a covariate. FINDINGS: Of 201 included trials (94 753 participants), 152 reported a consumption outcome that could be converted to grams/week; 104 reported number of single high intensity drinking episodes. At 1 and 6 months, practitioner delivered interventions reduced consumption more than digitally delivered interventions (1 month: -23 g/wk (95% CI, -43 to -2); 6 months: -14 g/wk [95% CI, -25 to -3]). At 12 months there was no evidence of difference between practitioner and digitally delivered interventions (-6 g/wk [95% CI, -24 to 12]). There was no evidence of a difference in single high intensity drinking episodes between practitioner and digitally delivered interventions at any time point. Effect sizes were small, but could impact across a population with relatively high prevalence of hazardous and harmful drinking. Heterogeneity was a concern. Some inconsistency was indicated at 1 and 6 months, but little evidence was apparent at 12 months. CONCLUSION: Practitioner delivered interventions for reducing hazardous and harmful alcohol consumption are more effective than digitally delivered interventions up to 6 months; at 12 months there is no evidence of a difference.

Are older patients less likely to be treated for pancreatic cancer? A systematic review and meta-analysis.

Pancreatic cancer is the seventh commonest cause of cancer-related death worldwide. Although prognosis is poor, both surgery and adjuvant chemotherapy improve survival. However, it has been suggested that not all pancreatic cancer patients who may benefit from treatment receive it. This systematic review and meta-analysis investigated the existence of age-related inequalities in receipt of first-line pancreatic cancer treatment. Medline, Embase, Cochrane Library and grey literature were searched for population-based studies investigating treatment receipt, reported by age, for patients with primary pancreatic cancer from inception until 4th June 2020, and updated 5th August 2021. Studies from countries with universal healthcare were included, to minimise influence of health system-related economic factors. A modified version of the Newcastle-Ottawa Scale was used to assess risk of bias. Random-effects meta-analysis was undertaken comparing likelihood of treatment receipt in older versus younger patients. Sensitivity and subgroup analyses were conducted. Eighteen papers were included; 12 independent populations were eligible for meta-analysis. In most studies, < 10% of older patients were treated. Older age (generally ≥65) was significantly associated with reduced receipt of any treatment (OR=0.14, 95% CI 0.10-0.21, n = 12 studies), surgery (OR=0.15, 95% CI 0.09-0.24, n = 9 studies) and chemotherapy as a primary treatment (OR=0.13, 95% CI 0.07-0.24, n = 5 studies). The effect of age was independent of methodological quality, patient population or time-period of patient diagnosis and remained in studies with confounder adjustment. The mean quality score of included studies was 6/8. Inequalities in receipt of healthcare interventions across social groups is a recognised concern internationally. This review shows that older age is significantly, and consistently, associated with non-receipt of treatment in pancreatic cancer. However, there are risks and side-effects associated with pancreatic cancer treatment. Further research on what influences patient and professional treatment decision-making is required to better understand these apparent inequalities.

Efficacy and Safety of Triiodothyronine Treatment in Cardiac Surgery or Cardiovascular Diseases: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Low levels of the active thyroid hormone triiodothyronine (T3) in cardiac patients are associated with worse outcomes. The aim of this analysis was to assess if T3 treatment is beneficial and safe in patients undergoing cardiac surgery or those with cardiovascular diseases in whom there is observed or expected reduction in serum T3 levels. Methods: A systematic review and meta-analysis of randomized controlled trials (RCTs) was performed as per the PRISMA guidelines. Pubmed, EMBASE, and Web of Science databases were searched for RCTs published between January 1, 1960 and March 30, 2022 that evaluated the effects of T3 therapy in patients undergoing cardiac surgery or with cardiovascular diseases. The primary outcomes were measures of cardiac function. Weighted mean difference (MD) or relative risk was calculated using a random effects model. PROSPERO registration number CRD42020211966. Results: Of the 3181 full-text articles screened, 34 studies with 2547 participants (number ranging between 13 and 223, mean ages between 0.5 and 73 years, mean percentage of women between 7% and 64%) were included. In 12 RCTs with 1093 adults undergoing cardiac surgery T3 therapy was associated with improvement in cardiac index (MD [95% confidence interval], 0.24 [0.08 to 0.40] L/min/m2, I2 = 74%). The quality of evidence was high to moderate. In 3 RCTs with 188 children undergoing cardiac surgery, 3 RCTs with 131 adult cardiac donors, 3 RCTs with 83 adult patients with heart failure, and 2 RCTs with 89 adults with acute myocardial infarction, T3 therapy did not improve cardiac index or left ventricular function; the quality of evidence ranged from high (pediatric cardiac surgery) to low (other groups). No detrimental effect of T3 therapy was observed on heart rate, risk of in-hospital atrial fibrillation, or mortality. Conclusions: Short-term T3 therapy is safe and trials in adults undergoing cardiac surgical procedures to evaluate longer term clinical endpoints are required. Current data do not support the routine use of T3 therapy in children undergoing cardiac surgery or in cardiac donors. Adequately designed trials are required to determine if T3 therapy improves cardiac function and clinical outcomes in patients with heart failure or acute myocardial infarction.

Surgical treatment of clavicle fractures in the adolescent athlete.

CONTEXT: Current literature has clearly shown that the indications for surgical treatment of clavicle fractures in adults are expanding. Although clavicle fractures in children and adolescents have traditionally been treated nonoperatively, surgical treatment of displaced clavicle fractures may be indicated for adolescent athletes. EVIDENCE ACQUISITION: A review of relevant articles published between 1970 and 2013 was completed using MEDLINE and the terms clavicle fracture and adolescent athlete. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 3. RESULTS: Excellent outcomes and rapid return to competition can be achieved with surgical management of displaced clavicle fractures in the adolescent athlete with high functional demands similar to those of their adult counterparts. Complications include hardware irritation, screw loosening, pin migration, peri-incisional numbness, and refracture. Athletes and families must be counseled regarding complications and potential need for secondary surgery to remove hardware. CONCLUSION: The adolescent athlete with a displaced, shortened, or comminuted clavicle fracture presents a unique, controversial dilemma for the surgeon. Earlier return to competition can be achieved with surgical management to restore length and alignment and may prevent malunion, nonunion, and poor outcomes.

Supraspinatus and infraspinatus compartment syndrome following scapular fracture.

Acute compartment syndrome occurs when pressure within a confined fascial space rises to a level impairing microvascular perfusion to surrounding tissues.[1234567] The majority of the reported literature is based on lower extremity compartment syndrome, but any muscle group within an osteofascial compartment has the potential to develop compartment syndrome. We report a case of a 64-year-old male who developed an acute compartment syndrome of both the supraspinatus and infraspinatus after sustaining a severely comminuted scapula fracture. Diagnosis of compartment syndrome was made after intracompartmental pressure measurements of the supraspinatus and infraspinatus revealed pressures within 30 mmHg of the diastolic blood pressure, prompting emergency decompressive fasciotomy. At final follow-up, the examination revealed full shoulder strength with near-full range of motion. There were no signs of sequelae from compartment syndrome at any point. Few case reports describe compartment syndrome of the periscapular fascial compartments. However, these cases were either retrospectively diagnosed[89] or diagnosed via magnetic resonance imaging (MRI) findings and lab values.[910] Surgical management of acute compartment syndrome of the supraspinatus has been reported in only one other case.[10] To our knowledge, we report the only case of a patient with acute compartment syndrome of both the supraspinatus and infraspinatus compartments treated with emergent decompressive fasciotomy. Due to the devastating complications and functional loss of a missed diagnosis of compartment syndrome, a high index of clinical suspicion for developing compartment syndrome must be maintained in every fracture setting, regardless of anatomic location or rarity of reported cases.
