Review
The present study was conducted to analyze the erosive potential of the ever-increasing consumption of carbonated drinks on the dental surface. To identify relevant studies, a comprehensive search was conducted on PubMed, Scopus, and Web of Science covering the last 5 years (2018-2023) using the following Boolean keywords: "soft drinks AND tooth". Finally, a total of 19 studies were included. The initial search provided a total of 407 items. Nineteen records were finally involved in the inclusion phase, seven of which were in vivo and twelve in vitro. An abuse of carbonated acid substances leads to an increase in the possibility of dental erosion with consequent structural disintegration and reduction of the physical and mechanical properties of the enamel. There is thus greater bacterial adhesion on rougher surfaces, determined by the erosive process, and therefore a greater risk of caries. The pH of most commercialized carbonated drinks is lower than the critical pH for the demineralization of the enamel. Carbonated drinks' pH and duration of exposure have different deleterious effects on enamel.

Meta-Analysis Review
BACKGROUND
It is thought that infrabony defect morphology affects the outcome of periodontal regenerative surgery. However, this has not been systematically investigated.
AIMS
To investigate how well defect morphology is described in papers reporting regenerative therapy of periodontal infrabony defects and to investigate its effect on clinical and radiographic outcomes.
MATERIALS AND METHODS
A search was conducted in 3 electronic databases for publications reporting clinical and radiographic outcomes of periodontal intra-bony defects after regenerative therapy, divided by defect morphology.
RESULTS
The initial search resulted in 4487 papers, reduced to 143 after first and second screening. Fifteen of these publications were suitable for a fixed-effects meta-analysis. Initial defect depth was found to influence radiographic bone gain 12 months post-surgery, while narrower angles and increased number of walls influenced both radiographic bone gain and clinical attachment level (CAL) gain at 12 months. These associations seemed to occur irrespective of biomaterials used. Risk of bias ranged from low to high.
CONCLUSION
Deeper defects with narrower angles and increased number of walls exhibit improved CAL and radiographic bone gain at 12 months post-regenerative surgery. More data are needed about other aspects of defect morphology such as extension to buccal/lingual surfaces.

Meta-Analysis Review
Effectiveness of interventions to prevent pressure injury in adults admitted to intensive care settings: A systematic review and meta-analysis of randomised controlled trials.
OBJECTIVE
The aim of the study was to investigate the effectiveness of interventions to prevent pressure injury in adults admitted to intensive care settings.
REVIEW METHOD USED
This is a systematic review and meta-analysis of randomised controlled trials.
DATA SOURCES
Five databases (CINAHL, MEDLINE, Scopus, Web of Science, and Embase) were searched in mid-2019. Searches were updated (in April 2020) to year end 2019.
REVIEW METHODS
From an overarching systematic review and meta-analysis examining the effectiveness of pressure injury preventative interventions in adults admitted to acute hospital settings, trials conducted in intensive care were separated for an intensive care-specific synthesis. Two reviewers, with a third as an arbitrator, undertook study selection, data extraction, and risk-of-bias assessment. Included trials were grouped by intervention type for narrative synthesis and for random-effects meta-analysis using intention-to-treat data where appropriate.
RESULTS
Overall, 26 trials were included. Ten intervention types were found (support surfaces, prophylactic dressings, positioning, topical preparations, continence management, endotracheal tube securement, heel protection devices, medication, noninvasive ventilation masks, and bundled interventions). All trials, except one, were at high or unclear risk of bias. Four intervention types (endotracheal tube securement, heel protection devices, medication, and noninvasive ventilation masks) comprised single trials. Support surface trials were limited to type (active, reactive, seating, other). Meta-analysis was undertaken for reactive surfaces, but the intervention effect was not significant (risk ratio = 0.24, p = 0.12, I = 51%). Meta-analyses demonstrated the effectiveness of sacral (risk ratio = 0.22, p < 0.001, I = 0%) and heel (risk ratio = 0.31, p = 0.02; I = 0%) prophylactic dressings for pressure injury prevention.
CONCLUSIONS
Only prophylactic sacral and heel dressings demonstrated effectiveness in preventing pressure injury in adults admitted to intensive care settings. Further intensive care-specific trials are required across all intervention types. To minimise bias, we recommend that all future trials are conducted and reported as per relevant guidelines and recommendations.

The American Journal of Sports Medicine May 2023No study has provided a comprehensive systematic review of sports injuries on artificial turf versus natural grass.
BACKGROUND
No study has provided a comprehensive systematic review of sports injuries on artificial turf versus natural grass.
PURPOSE
To comprehensively examine the risk of overall injuries and multiple types of lower extremity injuries across all sports, all levels of competition, and on both old-generation and new-generation artificial turf.
STUDY DESIGN
Systematic review; Level of evidence, 3.
METHODS
A systematic review of the English-language literature was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. All included articles compared overall injury rates or lower extremity (hip, knee, or foot and ankle) injury rates on artificial turf and natural grass. All sports, levels of competition, and turf types were included. Studies were excluded if they did not include overall injury rates or lower extremity injury rates. Because of the heterogeneity of the included studies, no attempt was made to aggregate risk ratios to conduct a quantitative meta-analysis.
RESULTS
A total of 53 articles published between 1972 and 2020 were identified for study inclusion. Most studies on new-generation turf (13/18 articles) found similar overall injury rates between playing surfaces. When individual anatomic injury locations were analyzed, the greatest proportion of articles reported a higher foot and ankle injury rate on artificial turf compared with natural grass, both with old-generation (3/4 articles) and new-generation (9/19 articles) turf. Similar knee and hip injury rates were reported between playing surfaces for soccer athletes on new-generation turf, but football players, particularly those at high levels of competition, were more likely to sustain a knee injury on artificial turf than on natural grass.
CONCLUSION
The available body of literature suggests a higher rate of foot and ankle injuries on artificial turf, both old-generation and new-generation turf, compared with natural grass. High-quality studies also suggest that the rates of knee injuries and hip injuries are similar between playing surfaces, although elite-level football athletes may be more predisposed to knee injuries on artificial turf compared with natural grass. Only a few articles in the literature reported a higher overall injury rate on natural grass compared with artificial turf, and all of these studies received financial support from the artificial turf industry.

The effects and the prescription parameters of therapeutic exercise are not clear. For this reason, is needed to determine the effect of neuromuscular exercise on balance, muscle strength and flexibility specifying the parameters and characteristics of effective interventions in children between 6 and 12 years and adolescent between 13 and 18 years with Down Syndrome. The present study is a systematic review of effectiveness outcomes balance, muscle strength and flexibility in this population. The databases of PubMed, PEDro, EMBASE, SCIELO, Lilacs, Cochrane library were searched from May to December 2021. We recruited randomized controlled trials (RCTs) which met the inclusion criteria in our study. Ten studies were included. The interventions included mechanotherapy, vibration, and use of different unstable surfaces. The exercise frequency ranged from 3 to 5 days a week, and the duration of each session was between six and 15 min. The frequency was between two and three times a week for 6 and 12 weeks and the intensity were between 60 and 80% of maximal voluntary contraction. Neuromuscular exercise in different modes of application was associated with increases in chest and lower limb muscle strength mean 8.51, CI [2.35-14.67] kg and (21.54 [1.64, 41.43]) kg. Balance also improved when the mode of application was isokinetic training and core stability exercises (- 0.20 [- 0.29, - 0.12]) evaluated with stability index. Neuromuscular exercise appears to be effective for the improvement of both lower limb and chest muscle strength and balance in children over 8 years. No evidence was found in children under 8 years.

The aim of this study was to summarise the best evidence for the prevention and control of pressure ulcer at the support surface based on the site and stage of the pressure ulcer in order to reduce the incidence of pressure ulcer and improve the quality of care. In accordance with the top-down principle of the 6 S model of evidence-based resources, evidence from domestic and international databases and websites on the prevention and control of pressure ulcer on support surfaces, including randomised controlled trials, systematic reviews, evidence-based guidelines, and evidence summaries, was systematically searched for the period from January 2000 to July 2022. Evidence grading based on the Joanna Briggs Institute Evidence-Based Health Care Centre Evidence Pre-grading System (2014 version), Australia. The outcomes mainly embraced 12 papers, including three randomised controlled trials, three systematic reviews, three evidence-based guidelines, and three evidence summaries. The best evidence summarised included a total of 19 recommendations in three areas: type of support surface selection assessment, use of support surfaces, and team management and quality control.

Worldviews on Evidence-based Nursing Apr 2022Pressure injury (PI) is a significant health problem among inpatients that affects their health, quality of life, and expenses. (Review)
Review
BACKGROUND
Pressure injury (PI) is a significant health problem among inpatients that affects their health, quality of life, and expenses.
AIM
This systematic review aimed to compare effects of alternating pressure air mattresses (APMs) with other types of supporting surfaces as a tool for PI prevention.
METHODS
The literature published between 2009 and 2020 was searched using the databases PubMed, EMBASE, CINAHL, and Cochrane. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses process was followed, including independent study selection and data extraction. Quality appraisal was conducted using the Cochrane Risk of Bias Tool (RoB 2.0).
RESULTS
A total of six randomized controlled trials (RCTs) were analyzed. The incidence of hospital-acquired PIs at stage 1 or higher was reported in the APM group from 0.3% to 25%. In one study, APMs were found to be less effective than static air mattresses (SAMs); in contrast, two studies found no difference. In one study, the APM was reported to be more effective than the viscoelastic foam mattress (VFM). On the contrary, in a more recent study, the APM was reported to be less effective than the VFM, and there was no difference compared with high-specification foam mattresses in another study. Using the RoB 2.0 tool, one study was evaluated at "low risk of bias," another as "some concern," and four as "high risk."
LINKING EVIDENCE TO ACTION
There is insufficient evidence to suggest that APM is more effective in preventing PIs than other supporting surfaces. Evidence to date suggests that APM can be used in patients at risk for PIs. It is important to change position regardless of the type of support surface used. Highly controlled RCTs with low risk of bias are needed to provide strong evidence for identifying the most effective PI prevention support surfaces.

Review
BACKGROUND
Fracture resistance of endodontically treated tooth is affected due to large cavity designs and access cavities and an appropriate material capable to resist fracture plays an important role. This review aims to evaluate the effect of fibre-reinforced composite (FRC) as a post-obturation material on fracture resistance of endodontically treated teeth.
OBJECTIVES
To systematically gather and evaluate the fracture resistance of fibre-reinforced composite as a post-obturation restorative material in endodontically treated teeth.
DATA SOURCES
A systematic search was conducted using PubMed, Ebsco Host, Scopus, Google Scholar, Hinari and manual search library resources from 1st Jan 2000 to 30th November 2019 to identify appropriate studies.
RESULT
A total of 157 articles were examined out of which 55 articles were selected after reading the title. After removing the duplicates, 27 articles were screened for abstract and 1 article was eliminated as it did not meet the eligibility criteria. A thorough reading of the full text of the remaining 26 selected articles was assessed for eligibility. Amongst these, 1 article was then excluded from the study as the full text was not accessible. Lastly, 25 articles were included in the study.
CONCLUSION
FRC as a core material increases fracture resistance of endodontically treated teeth but they do not have the fracture resistance similar to the intact tooth. Both polyethylene and short fibre-reinforced composites showed greater fracture resistance when compared to glass FRC and restoration without reinforcement. Also, the fracture resistance increases if restored with FRC along with retention slots and are placed on the occlusal third surfaces of cavities. Also, favourable fractures were most commonly seen and it usually occurred at the level of enamel and dentin and adhesive fractures were seen.

Meta-Analysis
BACKGROUND
Pressure ulcers (also known as pressure injuries, pressure sores, decubitus ulcers and bed sores) are localised injuries to the skin or underlying soft tissue, or both, caused by unrelieved pressure, shear or friction. Alternating pressure (active) air surfaces are widely used with the aim of preventing pressure ulcers.
OBJECTIVES
To assess the effects of alternating pressure (active) air surfaces (beds, mattresses or overlays) compared with any support surface on the incidence of pressure ulcers in any population in any setting.
SEARCH METHODS
In November 2019, we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting.
SELECTION CRITERIA
We included randomised controlled trials that allocated participants of any age to alternating pressure (active) air beds, overlays or mattresses. Comparators were any beds, overlays or mattresses.
DATA COLLECTION AND ANALYSIS
At least two review authors independently assessed studies using predetermined inclusion criteria. We carried out data extraction, 'Risk of bias' assessment using the Cochrane 'Risk of bias' tool, and the certainty of the evidence assessment according to Grading of Recommendations, Assessment, Development and Evaluations methodology.
MAIN RESULTS
We included 32 studies (9058 participants) in the review. Most studies were small (median study sample size: 83 participants). The average age of participants ranged from 37.2 to 87.0 years (median: 69.1 years). Participants were largely from acute care settings (including accident and emergency departments). We synthesised data for six comparisons in the review: alternating pressure (active) air surfaces versus: foam surfaces, reactive air surfaces, reactive water surfaces, reactive fibre surfaces, reactive gel surfaces used in the operating room followed by foam surfaces used on the ward bed, and another type of alternating pressure air surface. Of the 32 included studies, 25 (78.1%) presented findings which were considered at high overall risk of bias.
PRIMARY OUTCOME
pressure ulcer incidence Alternating pressure (active) air surfaces may reduce the proportion of participants developing a new pressure ulcer compared with foam surfaces (risk ratio (RR) 0.63, 95% confidence interval (CI) 0.34 to 1.17; I = 63%; 4 studies, 2247 participants; low-certainty evidence). Alternating pressure (active) air surfaces applied on both operating tables and hospital beds may reduce the proportion of people developing a new pressure ulcer compared with reactive gel surfaces used on operating tables followed by foam surfaces applied on hospital beds (RR 0.22, 95% CI 0.06 to 0.76; I = 0%; 2 studies, 415 participants; low-certainty evidence). It is uncertain whether there is a difference in the proportion of people developing new pressure ulcers between alternating pressure (active) air surfaces and the following surfaces, as all these comparisons have very low-certainty evidence: (1) reactive water surfaces; (2) reactive fibre surfaces; and (3) reactive air surfaces. The comparisons between different types of alternating pressure air surfaces are presented narratively. Overall, all comparisons suggest little to no difference between these surfaces in pressure ulcer incidence (7 studies, 2833 participants; low-certainty evidence). Included studies have data on time to pressure ulcer incidence for three comparisons. When time to pressure ulcer development is considered using a hazard ratio (HR), it is uncertain whether there is a difference in the risk of developing new pressure ulcers, over 90 days' follow-up, between alternating pressure (active) air surfaces and foam surfaces (HR 0.41, 95% CI 0.10 to 1.64; I = 86%; 2 studies, 2105 participants; very low-certainty evidence). For the comparison with reactive air surfaces, there is low-certainty evidence that people treated with alternating pressure (active) air surfaces may have a higher risk of developing an incident pressure ulcer than those treated with reactive air surfaces over 14 days' follow-up (HR 2.25, 95% CI 1.05 to 4.83; 1 study, 308 participants). Neither of the two studies with time to ulcer incidence data suggested a difference in the risk of developing an incident pressure ulcer over 60 days' follow-up between different types of alternating pressure air surfaces. Secondary outcomes The included studies have data on (1) support-surface-associated patient comfort for comparisons involving foam surfaces, reactive air surfaces, reactive fibre surfaces and alternating pressure (active) air surfaces; (2) adverse events for comparisons involving foam surfaces, reactive gel surfaces and alternating pressure (active) air surfaces; and (3) health-related quality of life outcomes for the comparison involving foam surfaces. However, all these outcomes and comparisons have low or very low-certainty evidence and it is uncertain whether there are any differences in these outcomes. Included studies have data on cost effectiveness for two comparisons. Moderate-certainty evidence suggests that alternating pressure (active) air surfaces are probably more cost-effective than foam surfaces (1 study, 2029 participants) and that alternating pressure (active) air mattresses are probably more cost-effective than overlay versions of this technology for people in acute care settings (1 study, 1971 participants).
AUTHORS' CONCLUSIONS
Current evidence is uncertain about the difference in pressure ulcer incidence between using alternating pressure (active) air surfaces and other surfaces (reactive water surfaces, reactive fibre surfaces and reactive air surfaces). Alternating pressure (active) air surfaces may reduce pressure ulcer risk compared with foam surfaces and reactive gel surfaces used on operating tables followed by foam surfaces applied on hospital beds. People using alternating pressure (active) air surfaces may be more likely to develop new pressure ulcers over 14 days' follow-up than those treated with reactive air surfaces in the nursing home setting; but as the result is sensitive to the choice of outcome measure it should be interpreted cautiously. Alternating pressure (active) air surfaces are probably more cost-effective than reactive foam surfaces in preventing new pressure ulcers. Future studies should include time-to-event outcomes and assessment of adverse events and trial-level cost-effectiveness. Further review using network meta-analysis will add to the findings reported here.

BACKGROUND AND OBJECTIVES
Short bowel syndrome is a clinical condition defined by malabsorption of nutrients and micronutrients, most commonly following extensive intestinal resection. Due to a loss of absorptive surfaces, the absorption of orally administered drugs is also often affected. The purpose of this study was to systematically review the published literature and examine the effects of short bowel syndrome on drug pharmacokinetics and clinical outcomes.
METHODS
Studies were identified through searches of databases MEDLINE, EMBASE, Web of Science, and SCOPUS, in addition to hand searches of studies' reference lists. Two reviewers independently assessed studies for inclusion, yielding 50 studies involving 37 different drugs in patients with short bowel syndrome.
RESULTS
Evidence of decreased drug absorption was observed in 29 out of 37 drugs, 6 of which lost therapeutic effect, and 14 of which continued to demonstrate clinical benefit through drug monitoring.
CONCLUSIONS
The influence of short bowel syndrome on drug absorption appears to be drug-specific and dependent on the location and extent of resection. The presence of a colon in continuity may also influence drug bioavailability as it can contribute significantly to the absorption of drugs (e.g., metoprolol); likewise, drugs that have a wide absorption window or are known to be absorbed in the colon are least likely to be malabsorbed. Individualized dosing may be necessary to achieve therapeutic efficacy, and therapeutic drug monitoring, where available, should be considered in short bowel syndrome patients, especially for drugs with narrow therapeutic indices.
