Review
PURPOSE
The aim of the present systematic review was to investigate the influence of hypertension on the dental implant failure rate.
METHODS
An electronic search was undertaken in four databases, plus a manual search of journals. The I statistic was used to check heterogeneity and the inverse-variance method was used for the meta-analysis. The estimate of relative effect for dichotomous outcome was expressed as an odds ratio (OR).
RESULTS
The review included 24 publications. There were 4874 implants (257 failures) placed in hypertensive patients and 16,192 implants (809 failures) placed in normotensive patients. A pairwise meta-analysis showed that implants in hypertensive patients did not have a higher risk of failure than implants placed in normotensive patients (OR 1.100, = 0.671). The log OR of implant failure between hypertensive and normotensive patients did not significantly change with the follow-up time ( = 0.824).
CONCLUSIONS
This review suggests that implants in hypertensive patients do not present higher odds of failure in comparison to normotensive patients. However, further research on this topic, with the use of more rigorous criteria to diagnose patients as being hypertensive, as well as clearer information about the pharmacological management of the condition in the patients, is recommended.

Review
Vulnerable locations, such as coastlines, are at a high risk of loss and damage. Such places will suffer deleterious impacts as climate change impacts are increasingly realized. As societies try to adapt to these impacts, managed or planned retreat-aimed at moving people and assets away from vulnerable locations-is gaining increased attention. Despite this increased attention, systematic literature reviews of the retreat literature remain scarce. This paper undertakes such review and uncovers a marked increase in retreat scholarly research papers in the past 5 years. An analysis of 135 managed and planned retreat journal articles is completed. Findings include a strong emphasis on regional or local case studies exploring governance, policy or institutional settings and levers across a range of geographies. Property rights and market interventions, such as compensation schemes, evidence the prevalence of neoliberal predilections. This emphasizes the importance of renewed engagement with political economy scholarship vis-à-vis climate change adaptation, also supported by the sharp increase in the evidenced social and environmental justice impacts. This article is part of the theme issue 'Nurturing resilient marine ecosystems'.

Review
RATIONALE, AIMS AND OBJECTIVES
Complex and chronic disease is placing significant pressure on hospital outpatient departments. Novel ways of delivering care have been developed recently and are often described as 'triage' services. This paper reviews the literature pertaining to definitions and descriptions of orthopaedic/musculoskeletal triage processes, in order to provide information on 'best practice' to assist health care facilities.
METHOD
A comprehensive open-ended search was conducted using electronic databases to identify studies describing models of triage clinics for patients with a musculoskeletal/orthopaedic complaint, who have been referred to hospital outpatient clinics for a surgical consultation. Studies were critically appraised using the McMaster quality appraisal tool and ranked using the National Health and Medical Research Council hierarchy of evidence. A thematic analysis of the definitions, processes and procedures of triage described within the literature was undertaken.
RESULTS
1930 studies were identified and 45 were included in the review (including diagnostic and evaluative research). The hierarchy of evidence ranged from I to IV; however, the majority were at low levels of evidence and scored poorly on the critical appraisal tool. Three broad themes of triage were identified: presence of a referral, configuration of the triage (who, how and where) and the aim of triage. However, there were significant inconsistencies across these themes.
CONCLUSIONS
This systematic review highlighted the need for standardization of the definition of triage, the procedures of assessment and management and measures of outcome used in orthopaedic/musculoskeletal triage to ensure best-practice processes, procedures and outcomes for triage clinics.

Review
BACKGROUND
The use of Cannabis for Therapeutic Purposes (CTP) has recently become legal in many places. These policy and legal modifications may be related to changes in cannabis perceptions, availability and use and in the way cannabis is grown and sold. This may in turn have effects on public health and safety. To better understand the potential effects of CTP legalization on public health and safety, the current paper synthesizes and critically discusses the relevant literature.
METHODS
Twenty-eight studies were identified by a comprehensive search strategy, and their characteristics and main findings were systematically reviewed according to the following content themes: CTP and illegal cannabis use; CTP and other public health issues; CTP, crime and neighbourhood disadvantage.
RESULTS
The research field is currently limited by a lack of theoretical and methodological rigorous studies. The review shows that the most prevalent theme of investigation so far has been the relation between CTP and illegal cannabis use. In addition, the literature review shows that there is an absence of evidence to support many common concerns related to detrimental public health and safety effects of CTP legalization.
CONCLUSION
Although lack of evidence provides some reassurance that CTP legalization may not have posed a substantial threat to public health and safety, this conclusion needs to be examined in light of the limitations of studies conducted so far. Furthermore, as CTP policy continues to evolve, including incorporation of greater commercialization, it is possible that the full effects of CTP legalization have yet to take place. Ensuring study quality will allow future research to better investigate the complex role that CTP plays in relation to society at large, and public health and safety in particular.

Travel Medicine and Infectious Disease 2017To review infections associated with adventure travel. (Review)
Review
AIM
To review infections associated with adventure travel.
METHODS
The PubMed, Embase and Scopus databases were searched combining the words infection with the following keywords: rafting, whitewater, surfing, (surfer* or windsurf*), (caves or caving or spelunking), (triathlon or trekking) or (hiking or adventure race), bicycling, backpacking, (mountain climb* or bouldering), horseback riding, orienteering, trekking, and skiing.
RESULTS
Adventure travel is becoming much more common among travelers and it is associated with a subset of infectious diseases including: leptospirosis, schistosomiasis, viral hemorrhagic fevers, rickettsial diseases and endemic mycosis. Caving and whitewater rafting places individuals at particular risk of leptospirosis, schistosomiasis and endemic mycosis, while adventure races also place individuals at high risk of a variety of infections including campylobacter, norovirus and leptospirosis.
CONCLUSION
Travel practitioners need to be aware of the risks associated with adventure travel and should educate individuals about the risks associated with various activities. Doxycycline prophylaxis should be considered for travelers who are susceptible to leptospirosis due to participation in high-risk sports such as whitewater rafting, caving or adventure races.

Review
OBJECTIVES
The purpose of this systematic review and meta-analysis is to examine the success rate of osseointegrated dental implants placed secondarily in fibula free flaps using the Albrektsson and colleagues criteria.
MATERIAL AND METHODS
A computerized database search was performed using PubMed, Embase, Web of Science and Cochrane CENTRAL. Specific ascertainment criteria were applied for the inclusion of the eligible studies. This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis PRISMA checklist. Risk of bias was assessed for all the included studies.
RESULTS
The meta-analysis was carried using ten studies that met the inclusion criteria. The present review pooled data obtained from 242 patients (167 males and 75 females), with the age range of 13 to 79 years. A total of 848 dental implants were placed in the free fibula flaps. All dental implants were placed in a delayed fashion, ranging from 14 to 192 months. The estimated proportion of successful implants placed in fibula flaps used to reconstruct the maxillomandibular complex was 0.94 or 94% (95% CI [confidence interval] = 0.91 to 0.96]) with an insignificant heterogeneity of 37%, P = 0.12. Using a random effect model the annual implant failure rate was 0.02 with a 95% CI = 0.01 to 0.03.
CONCLUSIONS
The results of this systematic review and meta-analysis strongly indicate that using objective criteria, delayed implant placement in free fibula flaps is highly successful.

Review
Since 2016, numerous American and Canadian diplomats and secret (intelligence) agents in Cuba, China, and other places in the world have experienced an abrupt onset of unusual clinical symptoms including, tinnitus, visual problems, vertigo, and cognitive difficulties, after they encountered strange sounds; this has been called "Havana syndrome" (HS). MEDLINE, Scopus, and Ovid databases from 2016 until 24 September 2021 were systematically searched for the related published manuscripts. The following search strategy was implemented: "Havana syndrome" OR "Neurological Symptoms and US Diplomats". The primary search yielded 120 publications. Only five original studies and 18 non-original articles were considered to be relevant. While these studies provided a constellation of signs and symptoms for HS, none provided a good level of evidence. In conclusion, Havana syndrome is a nonspecific neurological illness with an unidentified causative factor(s), an acute phase of auditory-vestibular symptoms and a chronic phase of nonspecific neurobehavioral symptoms. This syndrome should be considered and investigated as a health concern, and not as a political issue.

BACKGROUND
Results of new studies should be interpreted in the context of what is already known to compare results and build the state of the science. This systematic review and meta-analysis aimed to identify and synthesise results from meta-research studies examining if original studies within health use systematic reviews to place their results in the context of earlier, similar studies.
METHODS
We searched MEDLINE (OVID), EMBASE (OVID), and the Cochrane Methodology Register for meta-research studies reporting the use of systematic reviews to place results of original clinical studies in the context of existing studies. The primary outcome was the percentage of original studies included in the meta-research studies using systematic reviews or meta-analyses placing new results in the context of existing studies. Two reviewers independently performed screening and data extraction. Data were synthesised using narrative synthesis and a random-effects meta-analysis was performed to estimate the mean proportion of original studies placing their results in the context of earlier studies. The protocol was registered in Open Science Framework.
RESULTS
We included 15 meta-research studies, representing 1724 original studies. The mean percentage of original studies within these meta-research studies placing their results in the context of existing studies was 30.7% (95% CI [23.8%, 37.6%], I=87.4%). Only one of the meta-research studies integrated results in a meta-analysis, while four integrated their results within a systematic review; the remaining cited or referred to a systematic review. The results of this systematic review are characterised by a high degree of heterogeneity and should be interpreted cautiously.
CONCLUSION
Our systematic review demonstrates a low rate of and great variability in using systematic reviews to place new results in the context of existing studies. On average, one third of the original studies contextualised their results. Improvement is still needed in researchers' use of prior research systematically and transparently-also known as the use of an evidence-based research approach, to contribute to the accumulation of new evidence on which future studies should be based.

Review
BACKGROUND
Discussion of place of birth is important for women and maternity services, yet the detail, content and delivery of these discussions are unclear. The Birthplace Study found that for low risk, multiparous women, there was no significant difference in neonatal safety outcomes between women giving birth in obstetric units, midwifery-led units, or home. For low risk, nulliparous women giving birth in a midwifery-led unit was as safe as in hospital, whilst birth at home was associated with a small, increased risk of adverse perinatal outcomes. Intervention rates were reduced in all settings outside hospital. NICE guidelines recommend all women are supported in their choice of birth setting. Midwives have the opportunity to provide information to women about where they choose to give birth. However, research suggests women are sometimes unaware of all the options available. This systematic review will establish what is known about midwives' perspectives of discussions with women about their options for where to give birth and whether any interventions have been implemented to support these discussions.
METHODS
The systematic review was PROSPERO registered (registration number: CRD42015017334). The PRISMA statement was followed. Medline, Cochrane, CINAHL, PsycINFO, Popline and EMBASE databases were searched between 2000-March 2015 and grey literature was searched. All identified studies were screened for inclusion. Qualitative data was thematically analysed, whilst quantitative data was summarised.
RESULTS
The themes identified relating to influences on midwives' place of birth discussions with women were organisational pressures and professional norms, inadequate knowledge and confidence of midwives, variation in what midwives told women and the influence of colleagues. None of the interventions identified provided sufficient evidence of effectiveness and were of poor quality.
CONCLUSIONS
The review has suggested the need for a pragmatic, understandable place of birth dialogue containing standard content to ensure midwives provide low risk women with adequate information about their place of birth options and the need to improve midwives knowledge about place of birth. A more robust, systematic evaluation of any interventions designed is required to improve the quality of place of birth discussions. By engaging with co-produced research, more effective interventions can be designed, implemented and sustained.

IMPORTANCE
Firearm homicide is a leading cause of injury death in the United States, and there is considerable debate over the effectiveness of firearm policies. An analysis of the effectiveness of firearm laws on firearm homicide is important to understand optimal policies to decrease firearm homicide in the United States.
OBJECTIVE
To evaluate the association between firearm laws and preventing firearm homicides in the United States.
EVIDENCE REVIEW
We evaluated peer-reviewed articles from 1970 to 2016 focusing on the association between US firearm laws and firearm homicide. We searched PubMed, CINAHL, Lexis/Nexis, Sociological Abstracts, Academic Search Premier, the Index to Legal Periodicals and Books, and the references from the assembled articles. We divided laws into 5 categories: those that (1) curb gun trafficking, (2) strengthen background checks, (3) improve child safety, (4) ban military-style assault weapons, and (5) restrict firearms in public places and leniency in firearm carrying. The articles were assessed using the standardized Guide to Community Preventive Services data collection instrument and 5 additional quality metrics: (1) appropriate data source(s) and outcome measure(s) were used for the study, (2) the time frame studied was adequate, (3) appropriate statistical tests were used, (4) the analytic results were robust, and (5) the disaggregated results of control variables were consistent with the literature.
FINDINGS
In the aggregate, stronger gun policies were associated with decreased rates of firearm homicide, even after adjusting for demographic and sociologic factors. Laws that strengthen background checks and permit-to-purchase seemed to decrease firearm homicide rates. Specific laws directed at firearm trafficking, improving child safety, or the banning of military-style assault weapons were not associated with changes in firearm homicide rates. The evidence for laws restricting guns in public places and leniency in gun carrying was mixed.
CONCLUSIONS AND RELEVANCE
The strength of firearm legislation in general, and laws related to strengthening background checks and permit-to-purchase in particular, is associated with decreased firearm homicide rates. High-quality research is important to further evaluate the effectiveness of these laws. Legislation is just 1 part of a multipronged approach that will be necessary to decrease firearm homicides in the United States.
