Review
BACKGROUND
Tooth decay is considered a global scourge by the World Health Organization (WHO) starting at an early age. In recent years, silver diamine fluoride (SDF) has regained interest, particularly in pediatric dentistry, used to prevent the development of carious lesions or arrest their progression.
OBJECTIVE
The aim of this study was to assess, through a systematic review of the literature, the effectiveness of SDF, used in pedodontics, in temporary teeth, in preventing or arresting dental caries.
MATERIAL AND METHODS
An electronic search was conducted on PubMed, Web of Science and Scopus. The effect of SDF on both temporary and permanent teeth has been considered.
RESULTS
The inclusion criteria identified 16 randomized controlled trials involving patients aged 18 months to 13 years and followed over a period of 12-30 months.
CONCLUSIONS
SDF is a practical, accessible and effective non-invasive way to prevent and arrest caries in temporary and permanent teeth. Its application requires regular monitoring. The resulting black spot is diminished by immediate application of potassium iodide but this may affect its effectiveness.

Meta-Analysis Review
Ethambutol (EMB) is a first-line antituberculosis drug; however, drug resistance to EMB has been increasing. Molecular drug susceptibility testing (DST), based on the embB gene, has recently been used for rapid identification of EMB resistance. The aim of this meta-analysis was to establish the accuracy of molecular assay for detecting drug resistance to EMB. PubMed, Embase, and Web of Science were searched according to a written protocol and explicit study selection criteria. Measures of diagnostic accuracy were pooled using a random effects model. A total of 34 studies were included in the meta-analysis. The respective pooled sensitivities and specificities were 0.57 and 0.93 for PCR-DNA sequencing that targeted the embB 306 codon, 0.76 and 0.89 for PCR-DNA sequencing that targeted the embB 306, 406, and 497 codons, 0.64 and 0.70 for detecting Mycobacterium tuberculosis isolates, 0.55 and 0.78 for detecting M. tuberculosis sputum specimens using the GenoType MTBDRsl test, 0.57 and 0.87 for pyrosequencing, and 0.35 and 0.98 for PCR-restriction fragment length polymorphism. The respective pooled sensitivities and specificities were 0.55 and 0.92 when using a lower EMB concentration as the reference standard, 0.67 and 0.73 when using a higher EMB concentration as the reference standard, and 0.60 and 1.0 when using multiple reference standards. PCR-DNA sequencing using multiple sites of the embB gene as detection targets, including embB 306, 406, and 497, can be a rapid method for preliminarily screening for EMB resistance, but it does not fully replace phenotypic DST. Of the reference DST methods examined, the agreement rates were the best using MGIT 960 for molecular DST and using the proportion method on Middlebrook 7H10 media.

Diisocyanates are a group of chemicals that are widely used in occupational settings. They are known to induce various health effects, including skin- and respiratory tract sensitization resulting in allergic dermatitis and asthma. Exposure to diisocyanates has been studied in the past decades by using different types of biomonitoring markers and matrices. The aim of this review as part of the HBM4EU project was to assess: (i) which biomarkers and matrices have been used for biomonitoring diisocyanates and what are their strengths and limitations; (ii) what are (current) biomonitoring levels of the major diisocyanates (and metabolites) in workers; and (iii) to characterize potential research gaps. For this purpose we conducted a systematic literature search for the time period 2000-end 2018, thereby focussing on three types of diisocyanates which account for the vast majority of the total isocyanate market volume: hexamethylene diisocyanate (HDI), toluene diisocyanate (TDI), and 4,4'-methylenediphenyl diisocyanate (MDI). A total of 28 publications were identified which fulfilled the review inclusion criteria. The majority of these studies (93%) investigated the corresponding diamines in either urine or plasma, but adducts have also been investigated by several research groups. Studies on HDI were mostly in the motor vehicle repair industry [with urinary hexamethylene diamine result ranging from 0.03 to 146.5 µmol mol-1 creatinine]. For TDI, there is mostly data on foam production [results for urinary toluene diamine ranging from ~0.01 to 97 µmol mol-1 creatinine] whereas the available MDI data are mainly from the polyurethane industry (results for methylenediphenyl diamine range from 0.01 to 32.7 µmol mol-1 creatinine). About half of the studies published were prior to 2010 hence might not reflect current workplace exposure. There is large variability within and between studies and across sectors which could be potentially explained by several factors including worker or workplace variability, short half-lives of biomarkers, and differences in sampling strategies and analytical techniques. We identified several research gaps which could further be taken into account when studying diisocyanates biomonitoring levels: (i) the development of specific biomarkers is promising (e.g. to study oligomers of HDI which have been largely neglected to date) but needs more research before they can be widely applied, (ii) since analytical methods differ between studies a more uniform approach would make comparisons between studies easier, and (iii) dermal absorption seems a possible exposure route and needs to be further investigated. The use of MDI, TDI, and HDI has been recently proposed to be restricted in the European Union unless specific conditions for workers' training and risk management measures apply. This review has highlighted the need for a harmonized approach to establishing a baseline against which the success of the restriction can be evaluated.

Meta-Analysis Review
Performance of 68Ga-labeled prostate-specific membrane antigen ligand positron emission tomography/computed tomography in the diagnosis of primary prostate cancer: a systematic review and meta-analysis.
OBJECTIVE
To explore the feasibility of 68Ga-PSMA PET/CT in diagnosing primary prostate cancer.
MATERIALS AND METHODS
Embase, PubMed and Cochrane Library databases were searched for studies published before July 2020. The studies that used 68Ga-PSMA PET/CT for detecting primary prostate cancer, and pathological biopsy as the reference standard were included. The selecting process used preferred reporting items for systematic reviews and meta-analyses (PRISMA). The quality of enrolled studies was assessed by the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool.
RESULTS
According to our search strategy, 9 studies were included for analysis. A total of 547 patients with primary prostate cancer and 443 lesion segments that underwent 68Ga-PSMA PET/CT scans were included and their pathological biopsies were compared. The results of these studies showed some differences. For instance, the lowest sensitivity of 68Ga-PSMA PET/CT in diagnosing primary prostate cancer was 67%, while the highest sensitivity recorded was 97%.
CONCLUSIONS
Compared with conventional imaging examinations, 68Ga-PSMA PET/CT had higher sensitivity and specificity in detecting primary prostate cancer. At present, most of the studies that used 68Ga-PSMA PET/CT for detecting prostate cancer are retrospective studies. Based on its advantage of high detection rate, the use of 68Ga-PSMA PET/CT in the detection of primary prostate cancer is worthy of promotion.

INTRODUCTION
Recently, clinical trials have assessed the effectiveness of Silver Diamine Fluoride (SDF) as an indirect pulp capping material (IPC) in primary teeth. This systematic review aimed to assess the evidence presented in these trials.
DATA SOURCES
A comprehensive search identified relevant studies through five electronic databases (PubMed, Scopus, ClinicalTrials.gov, ScienceDirect, and Cochrane). Search strategies were designed using the PICO model to identify all studies that investigated SDF as an IPC compared to calcium hydroxide (CaOH) or mineral trioxide aggregate (MTA). Quality assessment and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) were used to assess the level of evidence.
STUDY SELECTION
Four clinical trials were found to be suitable for inclusion in the qualitative synthesis and three studies were included in the quantitative analysis. Three studies compared SDF with CaOH and only one study compared SDF, CaOH, and MTA. Only one randomized controlled trial (RCT) had a low risk of bias, and the non-RCT study had a moderate risk of bias. The level of evidence based on the GRADE was low. Three out of four studies showed higher clinical and radiographic outcomes with SDF than with CaOH. One non-RCT study showed that SDF resulted in the least reparative dentin at the 6-months follow-up. The meta-analysis showed a non-significant difference between the SDF and CaOH groups (P = 0.36).
CONCLUSION
There is little evidence showing a higher clinical and radiographic outcome of SDF compared to CaOH as an IPC material in primary molars.
CLINICAL SIGNIFICANCE
This systematic review updates pediatric dentists regarding the effectiveness of using SDF as indirect pulp caping in primary teeth.

Review
Silver diamine fluoride (SDF) has been extensively researched and proven effective for caries prevention and arrest in children. Limited studies support its effectiveness in primary dentition at 38%. This systematic review examines the effectiveness of 38% silver diamine fluoride on control of dental caries in primary dentition. Multiple search engines and databases were searched in accordance with predefined inclusion-exclusion criteria. Quality assessment was done using Centre for Evidence-Based Medicine worksheets. Scientific works of literature were searched in October 2019 for articles. Four studies were identified that addressed the effectiveness of 38% SDF on deciduous dentition in children. All the four studies selected were controlled clinical trials. The cumulative results of the studies showed that 38% SDF application is efficacious and safe for the control of dental caries in primary teeth. Its advantages over different other techniques or placebo have been demonstrated. Based on this systematic review, 38% SDF is one of the best treatment approaches in control of dental caries in primary dentition.

Review
BACKGROUND
Due to the limited treatment options in antibiotic-associated diarrhea (AAD) in children, more effective treatments should be explored. Traditional Chinese medicine (TCM) has a long history in China, which has produced a pretty effect in clinical practice. Many randomized clinical trials (RCTs) have explored the effect of traditional Chinese medicine on treating AAD in children. However, there has been no systematic review or meta-analysis on the impact of TCM on AAD in children. The aim of this study was to systematically review RCTs on the effect of TCM in children with AAD.
METHODS
RCTs in the past ten years on TCM for AAD in children were included. We searched Electronic databases as much as possible. This paper was registered in PROSPERO (CRD42022301034).
RESULTS
26 studies were included in this systematic review. 25 studies reported the effects of TCM interventions on the total effective rate (RR = 1.20, CI 1.16 to 1.24; < 0.001). 7 studies reported the effects of TCM interventions on the time to change the shape of feces (MD = -1.37, CI -1.67 to -1.07; < 0.001). 17 studies reported the effects of TCM interventions (MD = -1.43, CI -1.71 to -1.15; < 0.001). The pooled results showed that there were no significant differences between the two groups in CD3+, CD4+, CD8+, CD4 : CD8, time for bowel sounds to return to normal, hs-CRP, and IgM. There was a significant difference between the two groups in frequency of diarrhea on the third day after TCM intervention, vomiting improvement time, diamine oxidase, IL-8, TNF, IgA, IgG, and average hospital stay.
CONCLUSIONS
TCM interventions combined with conventional therapy can improve the therapeutic effect of AAD in children. However, future studies are still needed for the low methodological quality.

BACKGROUND
Silver diamine fluoride (SDF) solution gains increasing popularity in arresting dentine caries in clinical practice. The aim of this systematic review was to summarize the findings from laboratory studies on the influence of SDF application on the bond strength of dentine to various adhesives and to glass ionomer cements (GICs).
METHODS
Two independent reviewers conducted a literature search in the databases Medline, Ovid, PubMed and Web of Science until 15th August 2019 using the search keywords ['bond strength'] AND ['silver diamine fluoride' OR 'silver diammine fluoride' OR 'SDF' OR 'silver fluoride' OR 'diamine silver fluoride']. Articles investigating the effect of SDF application on the bond strength of dentine to various adhesives and to GICs were included in this review. Information on how SDF application influenced the bond strength was extracted from the included articles. Besides, related information, e.g. test method of bond strength, concentration and brand of SDF, type of adhesive system and GIC, testing dental substrate, protocol of specimen preparation, and failure mode was also reviewed.
RESULTS
A total of 13 articles were included in this review, with 8 and 6 studies investigating the effect of SDF application on the bond strength of dentine to various adhesives and to GICs, respectively. Sound dentine as well as demineralized dentine created by chemical methods, e.g. immersing in a demineralizing solution, was commonly adopted as the testing dental substrate. The microtensile bond strength (mTBS) test was the predominant method employed. However, the bond strength values had large variations among studies, ranging from <10 to 162 Mpa. Regarding the bond strength to different adhesives, 4 studies indicated that SDF application followed by rinsing with water had no significant influence. However, another 4 studies reported reduced bond strength after SDF application. Regarding the bond strength to GICs, 4 studies concluded that SDF application had no adverse impact on the bond strength.
CONCLUSIONS
No solid conclusion can be drawn on the effect of SDF application on the bond strength of dentine to adhesives and to GICs due to the high degree of variation of the included studies.

Meta-Analysis Review
BACKGROUND
Chronic lung disease (CLD) occurs frequently in preterm infants. Bronchodilators have the potential effect of dilating small airways with muscle hypertrophy. Increased compliance and tidal volume and decreased pulmonary resistance have been documented with the use of bronchodilators in infants with CLD. Therefore, bronchodilators might have a role in the prevention and treatment of CLD.
OBJECTIVES
To determine the effect of bronchodilators given as prophylaxis or as treatment for CLD on mortality and other complications of preterm birth in infants at risk for or identified as having CLD.
SEARCH METHODS
On 2016 March 7, we used the standard strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 2), MEDLINE (from 1966), Embase (from 1980) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; from 1982). We searched clinical trials databases, conference proceedings and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. We applied no language restrictions.
SELECTION CRITERIA
Randomised and quasi-randomised controlled trials involving preterm infants were eligible for inclusion. Initiation of bronchodilator therapy for prevention of CLD had to occur within two weeks of birth. Treatment of patients with CLD had to be initiated before discharge from the neonatal unit. The intervention had to include administration of a bronchodilator by nebulisation, by metered dose inhaler (with or without a spacer device) or by intravenous or oral administration versus placebo or no intervention. Eligible studies had to include at least one of the following predefined clinical outcomes: mortality, CLD, number of days on oxygen, number of days on ventilator, patent ductus arteriosus (PDA), pulmonary interstitial emphysema (PIE), pneumothorax, intraventricular haemorrhage (IVH) of any grade, necrotising enterocolitis (NEC), sepsis and adverse effects of bronchodilators.
DATA COLLECTION AND ANALYSIS
We used the standard method described in the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011). Two review authors extracted and assessed all data provided by each study. We reported risk ratio (RR), risk difference (RD) and number needed to treat for an additional beneficial outcome (NNTB) with 95% confidence interval (CI) for dichotomous outcomes and mean difference (MD) for continuous data. We assessed the quality of the evidence by using the GRADE approach.
MAIN RESULTS
For this update, we identified one new randomised controlled trial investigating effects of bronchodilators in preterm infants. This study, which enrolled 73 infants but reported on 52 infants, examined prevention of CLD with the use of aminophylline. According to GRADE, the quality of the evidence was very low. One previously included study enrolled 173 infants to look at prevention of CLD with the use of salbutamol. According to GRADE, the quality of the evidence was moderate. We found no eligible trial that studied the use of bronchodilator therapy for treatment of individuals with CLD. Prophylaxis with salbutamol led to no statistically significant differences in mortality (RR 1.08, 95% CI 0.50 to 2.31; RD 0.01, 95% CI -0.09 to 0.11) nor in CLD (RR 1.03, 95% CI 0.78 to 1.37; RD 0.02, 95% CI -0.13 to 0.17). Results showed no statistically significant differences in other complications associated with CLD nor in preterm birth. Investigators in this study did not comment on side effects due to salbutamol. Prophylaxis with aminophylline led to a significant reduction in CLD at 28 days of life (RR 0.18, 95% CI 0.04 to 0.74; RD -0.35, 95% CI -0.56 to -0.13; NNTB 3, 95% CI 2 to 8) and no significant difference in mortality (RR 3.0, 95% CI 0.33 to 26.99; RD 0.08, 95% CI -0.07 to 0.22), along with a significantly shorter dependency on supplementary oxygen in the aminophylline group compared with the no treatment group (MD -17.75 days, 95% CI -27.56 to -7.94). Tests for heterogeneity were not applicable for any of the analyses, as each meta-analysis included only one study.
AUTHORS' CONCLUSIONS
Data are insufficient for reliable assessment of the use of salbutamol for prevention of CLD. One trial of poor quality reported a reduction in the incidence of CLD and shorter duration of supplementary oxygen with prophylactic aminophylline, but these results must be interpreted with caution. Additional clinical trials are necessary to assess the role of bronchodilator agents in prophylaxis or treatment of CLD. Researchers studying the effects of bronchodilators in preterm infants should include relevant clinical outcomes in addition to pulmonary mechanical outcomes. We identified no trials that studied the use of bronchodilator therapy for treatment of CLD.

Review
OBJECTIVE
This study was aimed at comparing the performance of light-cured (LC) silver diamine fluoride (SDF) to non-LC SDF in dental applications, in terms of various properties.
METHODS
Articles published until April 2023 were retrieved from electronic databases (PubMed, Scopus and Science Direct) according to Boolean operators, and the reference lists of the included articles were manually searched. The included articles were all full-text, original studies in English that assessed the effects of LC SDF compared with SDF alone. The risk of bias in the in vitro studies on dental materials was evaluated with the modified Consolidated Standards of Reporting Trials (CONSORT) checklist.
RESULTS
Six studies (five in vitro and one ex vivo) were included in qualitative analysis after a comprehensive manual search and electronic database search. Every study compared LC SDF versus non-LC SDF in terms of properties such as penetration depth, silver ion precipitation, dentine hardness, surface morphology and anti-bacterial characteristics. Four studies were categorised as low quality with a high risk of bias, whereas the remaining two studies were considered high quality with a low risk of bias.
CONCLUSION
In this investigation, LC SDF, compared with non-LC SDF, was found to be an efficacious approach for enhancing SDF properties. Future high-quality studies, particularly randomised clinical trials, remain necessary to verify these findings.
CLINICAL SIGNIFICANCE
The use of light curing with SDF can be a beneficial strategy that enhances SDF's clinical use. This review comparing various properties of LC SDF and non-LC SDF may help clinicians enhance clinical use and patient acceptance of LC SDF.
