The role of vitamin D and vitamin D deficiency in orthopaedics and traumatology-a narrative overview of the literature.

ABSTRACT: Vitamin D is considered to play an important role in musculoskeletal health. It's classical function is the regulation of calcium and phosphate homeostasis, thus ensuring a balanced bone metabolism that is characterised by an equal amount of bone resorption and bone formation. In the past decades, a plethora of pre-clinical and clinical studies reporting on potential health-beneficial properties of vitamin D have emerged. Moreover, there is an abundance of reports highlighting vitamin D deficiency and insufficiency in patients with almost innumerable diseases. Further, it is estimated that more than one billion people globally are affected by insufficient vitamin D levels. As such, research on vitamin D has been particularly popular over the past years. In orthopaedics and traumatology, most studies describe favourable effects of vitamin D in general. However, the relative importance of vitamin D is oftentimes debated. In this narrative review of the literature, we consider first, the properties of vitamin D and how vitamin D, vitamin D deficiency and the vitamin D receptor (VDR) impact on musculoskeletal health. Secondly, we provide an overview of studies reporting the prevalence of vitamin D deficiency in traumatology and diverse orthopaedic diseases including bone oncology. Lastly, we emphasise recent findings and touch on future perspectives in vitamin D research.

Project description:Few Orthopaedics and Traumatology journals from Latin America and Spain are indexed in major databases; controlled clinical trials published in these journals cannot be exhaustively retrieved using electronic literature searches. We aimed to identify, describe and assess the quality of controlled clinical trials published in Orthopaedics and Traumatology journals from Latin America and Spain through handsearching and evidence mapping methods. We identified controlled clinical trials published in eligible Orthopaedics/Traumatology journals in Spanish until July 2017 by handsearching. Data were extracted for controlled clinical trials main characteristics and the Cochrane risk of bias tool was used to assess the controlled clinical trials methodological quality. In addition, we mapped the main findings of these trials. As a result, we assessed 5631 references in 29 eligible journals of which 57 were controlled clinical trials (1.0%). Controlled clinical trials were published between 1995 and 2017 at a rate of 2.5 per year. Journals from Spain and Mexico published around 63% of the controlled clinical trials identified. The median sample size of patients enrolled was 60 (range = 30-300 participants). About conditions assessed, 38.5% of controlled clinical trials assessed issues related to knee conditions, 15.7% about hip and 10.5% about trauma or spine. The risk of bias domains most affected was selective reporting bias and random sequence generation. In addition, only two and seven trials had low risk of bias in all items related to participant/personnel and outcome assessment blindings, respectively. More than 40% of studies did not report differences on benefits/harms between the interventions assessed. As a conclusion, the number of controlled clinical trials published in Orthopaedics/Traumatology journals from Latin America and Spain is low. These controlled clinical trials had important methodological shortcomings and were judged as unclear or high risk of bias. These trials are now available in CENTRAL for their potential inclusion in systematic reviews and other documents of synthesis.

Project description:BackgroundGlobal health diplomacy (GHD) has become an important field of investigation due to health concerns increasingly entering the foreign policy domain. Much of the existing academic writing focuses on North-South cooperation in global health, and emphasizes the role of security and economic interests by Northern countries as drivers of GHD. Chile presents a favourable environment for an expanded involvement in future GHD activities. However, there is little knowledge about what has been driving Chile's integration of health into foreign policy, and little effort to appropriate knowledge from international relations theories to better theoretically grasp the emergence of GHD.MethodsTo fill this knowledge gap, we conducted a narrative literature review of the driving forces behind Chile's integration of health into foreign policy. Drawing on a popular analytical framework used in international relations scholarship, we identified driving forces of the integration of health into Chile foreign policy at three levels of analysis.ResultsAt the international/global level of analysis, the main driving forces were related to national security concerns and compliance with regulations of international organizations. At the regional level, GHD was driven by a commitment to regional solidarity through mutually beneficial cooperation in response to neoliberal reforms; health coordination in emergencies; and protection of indigenous peoples. Finally, at the domestic level, drivers identified include economic interests of various productive sectors and how health regulations might impact those; the high degree of social inequity which impacts on access to healthcare; and management of natural disasters.ConclusionHealth actions in the context of international relations in Chile are still mainly motivated by more traditional foreign policy interests rather than by a desire to satisfy health needs per se. This seems to conform with findings of existing GHD scholarship that emphasize the importance of security and economic interests as driving forces of GHD, and how health is often appropriated instrumentally within foreign policy settings to achieve other goals. But the review also reveals that in the context of South-South cooperation (and regional health diplomacy), solidarity and normative considerations can be important driving forces as well. Finally, the review demonstrates that there has been an evolution from chiefly domestically focused health policies (e.g. maternal and child nutrition treatment) towards internationally inspired integrated policies (e.g. maternal and child nutrition promotion aligned with international guidelines).
