Vitamin and Mineral Supplements for the Primary Prevention of Cardiovascular Disease and Cancer: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force.
IMPORTANCE
Cardiovascular disease and cancer are the 2 leading causes of death in the US, and vitamin and mineral supplementation has been proposed to help prevent these conditions.
OBJECTIVE
To review the benefits and harms of vitamin and mineral supplementation in healthy adults to prevent cardiovascular disease and cancer to inform the US Preventive Services Task Force.
DATA SOURCES
MEDLINE, PubMed (publisher-supplied records only), Cochrane Library, and Embase (January 2013 to February 1, 2022); prior reviews.
STUDY SELECTION
English-language randomized clinical trials (RCTs) of vitamin or mineral use among adults without cardiovascular disease or cancer and with no known vitamin or mineral deficiencies; observational cohort studies examining serious harms.
DATA EXTRACTION AND SYNTHESIS
Single extraction, verified by a second reviewer. Quantitative pooling methods appropriate for rare events were used for most analyses.
MAIN OUTCOMES AND MEASURES
Mortality, cardiovascular disease events, cancer incidence, serious harms.
RESULTS
Eighty-four studies (N=739 803) were included. In pooled analyses, multivitamin use was significantly associated with a lower incidence of any cancer (odds ratio [OR], 0.93 [95% CI, 0.87-0.99]; 4 RCTs [n=48 859]; absolute risk difference [ARD] range among adequately powered trials, -0.2% to -1.2%) and lung cancer (OR, 0.75 [95% CI, 0.58-0.95]; 2 RCTs [n=36 052]; ARD, 0.2%). However, the evidence for multivitamins had important limitations. Beta carotene (with or without vitamin A) was significantly associated with an increased risk of lung cancer (OR, 1.20 [95% CI, 1.01-1.42]; 4 RCTs [n=94 830]; ARD range, -0.1% to 0.6%) and cardiovascular mortality (OR, 1.10 [95% CI, 1.02-1.19]; 5 RCTs [n=94 506] ARD range, -0.8% to 0.8%). Vitamin D use was not significantly associated with all-cause mortality (OR, 0.96 [95% CI, 0.91-1.02]; 27 RCTs [n=117 082]), cardiovascular disease (eg, composite cardiovascular disease event outcome: OR, 1.00 [95% CI, 0.95-1.05]; 7 RCTs [n=74 925]), or cancer outcomes (eg, any cancer incidence: OR, 0.98 [95% CI, 0.92-1.03]; 19 RCTs [n=86 899]). Vitamin E was not significantly associated with all-cause mortality (OR, 1.02 [95% CI, 0.97-1.07]; 9 RCTs [n=107 772]), cardiovascular disease events (OR, 0.96 [95% CI, 0.90-1.04]; 4 RCTs [n=62 136]), or cancer incidence (OR, 1.02 [95% CI, 0.98-1.08]; 5 RCTs [n=76 777]). Evidence for benefit of other supplements was equivocal, minimal, or absent. Limited evidence suggested some supplements may be associated with higher risk of serious harms (hip fracture [vitamin A], hemorrhagic stroke [vitamin E], and kidney stones [vitamin C, calcium]).
CONCLUSIONS AND RELEVANCE
Vitamin and mineral supplementation was associated with little or no benefit in preventing cancer, cardiovascular disease, and death, with the exception of a small benefit for cancer incidence with multivitamin use. Beta carotene was associated with an increased risk of lung cancer and other harmful outcomes in persons at high risk of lung cancer.

Review
This scoping review aims to summarize the available evidence on strategies employed in preventing caries in patients with molar incisor hypo-mineralization (MIH). MIH refers to an enamel defect involving opacities, and sometimes post-eruptive degradation due to enamel porosity; resulting in outcomes ranging from a mild atypical caries to severe coronary destruction. A systematic review was conducted for literature in PubMed, Cochrane Library, Epistemonikos and Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS). The search was aimed at studies published between January 2010 and February 2022. Data were independently selected and extracted. 989 studies were found from the systematic search and 8 studies met the eligibility criteria. Most studies evaluated remineralization and cariogenic risk, both of which are crucial elements in caries prevention, as well as decreased sensitivity. The included studies investigated fluoride varnish, dental sealants, giomers, casein, and Icon as preventative methods for dental caries. Several methods for preventing dental caries in paediatric patients with MIH exist, but more research is needed to determine their effectiveness and safety. Any preventive intervention should consider the etiological aspects of the disease, the risk of caries, the type and extent of lesions, hypersensitivity level and patient's age. Collaboration between patients and carers is critical for disease diagnosis and caries prevention.

Journal of Clinical Nursing Jul 2019To explore the effectiveness of interventions aimed at pressure ulcer (PU) prevention in long-term older people care facilities (LOPC).
AIMS AND OBJECTIVES
To explore the effectiveness of interventions aimed at pressure ulcer (PU) prevention in long-term older people care facilities (LOPC).
BACKGROUND
Pressure ulcers cause suffering for patients and constitute a major financial burden. Although most PUs could be prevented, their number has remained high. To avoid unnecessary suffering and costs, PU prevention must be effective.
DESIGN
A systematic review.
METHODS
A systematic search was conducted in six electronic databases PubMed (MEDLINE), CINAHL, Web of Science Core Collection, Scopus, Cochrane Wounds Group Specialized Register and Cochrane Central Register of Controlled Trials. The inclusion criteria were: (a) study published in 2005-2017, (b) intervention with pre- and post-tests, focusing on PU prevention, (c) implemented in LOPC facilities, (d) persons >65 years as study population, and (e) outcomes reported as PU incidence or prevalence or healing time. The PRISMA guidelines were followed. The methodological quality of the studies was evaluated using the Joanna Briggs Institute's MAStARI critical appraisal checklist. The data were analysed with narrative synthesis.
RESULTS
The review included eighteen studies. The study designs were RCTs (n = 10), comparable cohort or case-control studies (n = 3), and descriptive or case series (n = 5). PU incidence in LOPC facilities decreased by using computerised decision-making support systems, PU prevention programmes, repositioning or advanced cushions. PU prevalence decreased with PU prevention programmes, by using advanced mattresses and overlays, or by adding protein and energy supplements to diet.
CONCLUSIONS
There are many ways to prevent PUs in LOPC facilities; no single effective way can be identified. One-third of the preventive interventions in LOPC facilities were effective. However, systematic evidence from randomised trials on preventive interventions of PUs in LOPC settings is still lacking.
RELEVANCE TO CLINICAL PRACTICE
The findings can be used in practice for selecting and in research for developing effective preventive interventions of PUs in LOPC facilities.

Obesity Facts 2018Current guidelines for prevention of obesity in childhood and adolescence are discussed.
OBJECTIVE
Current guidelines for prevention of obesity in childhood and adolescence are discussed.
METHODS
A literature search was performed in Medline via PubMed, and appropriate studies were analyzed.
RESULTS
Programs to prevent childhood obesity have so far remained mainly school-based and effects have been limited. Analyses by age group show that prevention programs have the best results in younger children (<12 years). Evidence-based recommendations for pre-school- and early school-aged children indicate the need for interventions that address parents and teachers alike. During adolescence, school-based interventions proved most effective when adolescents were addressed directly. To date, obesity prevention programs have mainly focused on behavior-oriented prevention. Recommendations for community- or environment-based prevention have been suggested by the German Alliance of Noncommunicable Diseases and include a minimum of 1 h of physical activity at school, promotion of healthy food choices by taxing unhealthy foods, mandatory standards for meals at kindergartens and schools as well as a ban on unhealthy food advertisement aimed at children.
CONCLUSION
Behavior-oriented prevention programs showed only limited long-term effects. Certain groups at risk for the development of obesity are not reached effectively by current programs. Although universally valid conclusions cannot be drawn given the heterogeneity of available studies, clearly combining behavior-based programs with community-based prevention to counteract an 'obesogenic environment' is crucial for sustainable success of future obesity prevention programs.

Due to the morbidity and mortality of mothers and fetuses developed by preeclampsia, preventive approaches have always been taken into account in high risk individuals. Systematic review studies contribute to make a better decision about the results of such studies. Accordingly, this study strived to systematically study the factors effective in the prevention of preeclampsia. The MEDLINE, ISI Web of Science, PubMed, Scopus, Google Scholar, and Proquest databases were systematically reviewed between January 2000 and May 2019. The quality of the studies was analyzed using the CONSORT checklist. A study was conducted on 29 quality interventional studies; 28 of which were RCT type, and on various factors such as anticoagulants (heparin, enoxaparin, Dalteparin and Nadroparin), aspirin, paravastatin, nitric oxide, yoga, micronutrients Such as l-Arginine, Folic Acid, Vitamin E and C, Phytonutrient, Lycopene and Vitamin D alone or in combination with Calcium. The results of this study showed that low molecular weight heparin, enoxaparin, PETN, yoga, L arginine, folic acid, vitamin D prevented preeclampsia alone or combined with calcium.

Meta-Analysis Review
OBJECTIVE
Explore the cost-effectiveness of lifestyle interventions and metformin in reducing subsequent incidence of type 2 diabetes, both alone and in combination with a screening programme to identify high-risk individuals.
DESIGN
Systematic review of economic evaluations.
DATA SOURCES AND ELIGIBILITY CRITERIA
Database searches (Embase, Medline, PreMedline, NHS EED) and citation tracking identified economic evaluations of lifestyle interventions or metformin alone or in combination with screening programmes in people at high risk of developing diabetes. The International Society for Pharmaco-economics and Outcomes Research's Questionnaire to Assess Relevance and Credibility of Modelling Studies for Informing Healthcare Decision Making was used to assess study quality.
RESULTS
27 studies were included; all had evaluated lifestyle interventions and 12 also evaluated metformin. Primary studies exhibited considerable heterogeneity in definitions of pre-diabetes and intensity and duration of lifestyle programmes. Lifestyle programmes and metformin appeared to be cost effective in preventing diabetes in high-risk individuals (median incremental cost-effectiveness ratios of £7490/quality-adjusted life-year (QALY) and £8428/QALY, respectively) but economic estimates varied widely between studies. Intervention-only programmes were in general more cost effective than programmes that also included a screening component. The longer the period evaluated, the more cost-effective interventions appeared. In the few studies that evaluated other economic considerations, budget impact of prevention programmes was moderate (0.13%-0.2% of total healthcare budget), financial payoffs were delayed (by 9-14 years) and impact on incident cases of diabetes was limited (0.1%-1.6% reduction). There was insufficient evidence to answer the question of (1) whether lifestyle programmes are more cost effective than metformin or (2) whether low-intensity lifestyle interventions are more cost effective than the more intensive lifestyle programmes that were tested in trials.
CONCLUSIONS
The economics of preventing diabetes are complex. There is some evidence that diabetes prevention programmes are cost effective, but the evidence base to date provides few clear answers regarding design of prevention programmes because of differences in denominator populations, definitions, interventions and modelling assumptions.

Journal of Dentistry Jan 2022To summarize the evidence on prevention of early childhood caries (ECC) by professionally or self-applied topical fluorides using network meta-analysis. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
To summarize the evidence on prevention of early childhood caries (ECC) by professionally or self-applied topical fluorides using network meta-analysis.
DATA
Randomized-controlled trials with minimum 1-year follow-up assessing caries-preventive effect among children younger than six years.
SOURCES
Eight electronic databases and grey literature.
STUDY SELECTION
After screening and data extraction, risk of bias assessment using Cochrane risk of bias tool 2.0 was done. Twenty-four trials were included, among which 17 were assessed as "high risk" and remaining as "low risk". Fifteen studies evaluated professionally-applied, and the other nine used self-applied topical fluorides. Ten studies on professionally-applied fluorides reporting the net caries increment (dmfs increment) at 2-years follow-up were included in Network meta-analysis (NMA). NMA and ranking the interventions were conducted using a frequentist random-effects approach and surface under the cumulative ranking command, followed by assessing the certainty of evidence using an extension of GRADE approach with CINeMA framework. Among the eight included interventions of professionally-applied fluorides, only two, i.e., 3-monthly 0.9% difluorosilane (DFS) and 6-monthly 5% sodium fluoride varnish were effective in preventing ECC compared to control with 3-monthly DFS application ranking higher than 6-monthly sodium fluoride varnish application.
CONCLUSION
Among all the professionally-applied topical fluoride interventions reviewed, very low to moderate evidence was found with 0.9% DFS application at 3-monthly intervals, which was ranked highest in prevention of ECC. Among the included studies on self-applied topical fluorides, the evidence was inconclusive due to heterogeneity among studies.
CLINICAL SIGNIFICANCE
The 0.9% DFS varnish applied every 3 months is most effective for preventing early childhood caries. The review recommends that good quality studies be conducted in future, comparing two or more interventions for both self- as well as professionally-applied topical fluoride agents with adequate follow-up.

Atencion Primaria 2019To assess the effectiveness of the interventions to prevent a pregnancy in adolescence.
OBJECTIVE
To assess the effectiveness of the interventions to prevent a pregnancy in adolescence.
DESIGN
Systematic review.
DATA SOURCES
The following databases were consulted: PubMed, CINAHL, Scopus, Cuiden Plus, LILACS, and IME, in order to identify interventions aimed at preventing a pregnancy in adolescence.
STUDY SELECTION
A total of 24 primary investigations, in which an educational program to prevent a pregnancy in the adolescence was evaluated, were selected. The quality of the selected studies was assessed according to the CASPe scale.
RESULTS
Educational programs for the modification of the teenage pregnancy rate show inconclusive results, as there are 2 studies that find a reduction, and 2 that find that there are no significant changes. For secondary outcomes, it was found that educational programs are effective for increasing the knowledge level about sexuality and contraceptive methods and changing attitudes about the risk of a teenage pregnancy or the use of contraceptive methods. There are no statistically significant differences between the studies with a positive and negative outcome (P>.05) for any of the results analysed in this review.
CONCLUSION
There is no a single intervention modality that is the most effective for prevention of a teenage pregnancy. More research is needed with a longitudinal approach that assess not only intermediate results, but also a modification in the pregnancy rate.

Review
INTRODUCTION
Adverse events in hospitals constitute a serious problem with grave consequences. Many studies have been conducted to gain an insight into this problem, but a general overview of the data is lacking. We performed a systematic review of the literature on in-hospital adverse events.
METHODS
A formal search of Embase, Cochrane and Medline was performed. Studies were reviewed independently for methodology, inclusion and exclusion criteria and endpoints. Primary endpoints were incidence of in-hospital adverse events and percentage of preventability. Secondary endpoints were adverse event outcome and subdivision by provider of care, location and type of event.
RESULTS
Eight studies including a total of 74 485 patient records were selected. The median overall incidence of in-hospital adverse events was 9.2%, with a median percentage of preventability of 43.5%. More than half (56.3%) of patients experienced no or minor disability, whereas 7.4% of events were lethal. Operation- (39.6%) and medication-related (15.1%) events constituted the majority. We present a summary of evidence-based interventions aimed at these categories of events.
CONCLUSIONS
Adverse events during hospital admission affect nearly one out of 10 patients. A substantial part of these events are preventable. Since a large proportion of the in-hospital events are operation- or drug-related, interventions aimed at preventing these events have the potential to make a substantial difference.

Review
OBJECTIVES
To evaluate the available evidence that the use of arginine-containing dental care products prevents the development of new caries lesions and the progression of existing lesions.
SEARCH METHODS
We performed a systematic literature search of databases including PubMed, the Cochrane Library and EMBASE.
SELECTION CRITERIA
We selected randomized controlled trials of treatment with arginine in fluoride-containing dental products measuring dental caries incidence or progression in children, adults and elderly subjects.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for risk of bias and evaluated overall study quality using the GRADE classification.
MAIN RESULTS
Due to conflicts of interest and weak transferability to Swedish conditions, no conclusions can be drawn from studies on the effects of arginine-fluoride toothpaste in children. Arginine-containing toothpaste costs about 40% more than basic fluoride toothpaste; to determine whether it is more cost-effective, the higher cost must be considered in relation to any additional caries-preventive effect. The literature review also disclosed some questionable research ethics: in several of the studies, the children in the control group used non-fluoride toothpaste. Toothpaste without fluoride is not as effective against dental caries as the standard treatment - fluoride toothpaste - which has a well-documented effect. This contravenes the fundamental principles of research ethics.
CONCLUSION
At present there is insufficient evidence in support of a caries-preventive effect for the inclusion of arginine in toothpastes. More rigorous studies, and studies which are less dependent on commercial interests, are required.
