For the same age, sex, and dosage, there can be significant variation in fertility outcomes in childhood cancer survivors. Genetics may explain this variation. This study aims to: (i) review the genetic contributions to infertility, (ii) search for pharmacogenomic studies looking at interactions of cancer treatment, genetic predisposition and fertility-related outcomes. Systematic searches in MEDLINE Ovid, Embase Classic+Embase, and PubMed were conducted using the following selection criteria: (i) pediatric, adolescent, and young adult cancer survivors, below 25 years old at the time of diagnosis, (ii) fertility outcome measures after cancer therapy, (iii) genetic considerations. Studies were excluded if they were (i) conducted in animal models, (ii) were not published in English, (iii) editorial letters, (iv) theses. Articles were screened in Covidence by at least two independent reviewers, followed by data extraction and a risk of bias assessment using the Quality in Prognostic Studies tool. Eight articles were reviewed with a total of 29 genes. Outcome measures included sperm concentration, azoospermia, AMH levels, assessment of premature menopause, ever being pregnant or siring a pregnancy. Three studies included replication cohorts, which attempted replication of SNP findings for NPY2R, BRSK1, FANCI, CYP2C19, CYP3A4, and CYP2B6. Six studies were rated with a high risk of bias. Differing methods may explain a lack of replication, and small cohorts may have contributed to few significant findings. Larger, prospective longitudinal studies with an unbiased genome-wide focus will be important to replicate significant results, which can be applied clinically.

Dentistry Journal May 2024To compare the clinical effectiveness of ion-releasing restorations (IRR) vs. composite resin (CR) in dental restorations. (Review)
Review
BACKGROUND
To compare the clinical effectiveness of ion-releasing restorations (IRR) vs. composite resin (CR) in dental restorations.
METHODS
A systematic search was carried out from articles published until January 2024, in the biomedical databases: PubMed, Cochrane Library, Scielo, Scopus, Web of Science and Google Scholar. Randomized clinical trials were included, with a follow-up time greater than or equal to 1 year, without time and language limits and which reported the clinical effect of IRR compared to CR in dental restorations. The RoB 2.0 tool was used to assess the risk of bias of the included studies and the GRADEPro GDT tool was used to assess the quality of evidence and the strength of recommendation of the results.
RESULTS
The search yielded a total of 1109 articles. After excluding those that did not meet the selection criteria, 29 articles remained for the quantitative synthesis. The analysis found no statistically significant difference when comparing the dental restorations with IRRs or CRs.
CONCLUSION
The literature reviewed suggests that there are no differences between the IRRs and CRs in dental restorations.

Meta-Analysis
BACKGROUND
Catheter ablation and antiarrhythmic drug therapy are utilized for rhythm control in atrial fibrillation (AF), but their comparative effectiveness, especially with contemporary treatment modalities, remains undefined. We conducted a systematic review and meta-analysis contrasting current ablation techniques against antiarrhythmic medications for AF.
METHODS
We searched PubMed, SCOPUS, Cochrane CENTRAL, and Web of Science until November 2023 for randomized trials comparing AF catheter ablation with antiarrhythmics, against antiarrhythmic drug therapy alone, reporting outcomes for > 6 months. Four investigators extracted data and appraised risk of bias (ROB) with ROB 2 tool. Meta-analyses estimated pooled efficacy and safety outcomes using R software.
RESULTS
Twelve trials (n = 3977) met the inclusion criteria. Catheter ablation was associated with lower AF recurrence (relative risk (RR) = 0.44, 95%CI (0.33, 0.59), P ˂ 0.0001) and hospitalizations (RR = 0.44, 95%CI (0.23, 0.82), P = 0.009) than antiarrhythmic medications. Catheter ablation also improved the physical quality of life component score (assessed by a 36-item Short Form survey) by 7.61 points (95%CI -0.70-15.92, P = 0.07); but, due to high heterogeneity, it was not statistically significant. Ablation was significantly associated with higher procedural-related complications [RR = 15.70, 95%CI (4.53, 54.38), P < 0.0001] and cardiac tamponade [RR = 9.22, 95%CI (2.16, 39.40), P = 0.0027]. All-cause mortality was similar between the two groups.
CONCLUSIONS
For symptomatic AF, upfront catheter ablation reduces arrhythmia and hospitalizations better than continued medical therapy alone, albeit with moderately more adverse events. Careful patient selection and risk-benefit assessment are warranted regarding the timing of ablation.

Review
BACKGROUND
Long-term post-treatment surveillance imaging algorithms for head and neck squamous cell carcinoma are not standardized due to debates over optimal surveillance strategy and efficacy. Consequently, current guidelines do not provide long-term surveillance imaging recommendations beyond 6 months.
PURPOSE
We performed a systematic review to evaluate the impact of long-term imaging surveillance (i.e., imaging beyond 6 months following treatment completion) on survival in patients treated definitively for head and neck squamous cell carcinoma.
DATA SOURCES
A search was conducted on PubMed, Embase, Scopus, the Cochrane Central Register of Controlled Trials, and Web of Science for English literature published between 2003 and 2024 evaluating the impact of long-term surveillance imaging on survival in patients with head and neck squamous cell carcinoma.
STUDY SELECTION
718 abstracts were screened and 9 underwent full-text review, with 2 articles meeting inclusion criteria. The Risk of Bias in Non-randomized Studies of Interventions assessment tool was used.
DATA ANALYSIS
A qualitative assessment without a pooled analysis was performed for the two studies meeting inclusion criteria.
DATA SYNTHESIS
No randomized prospective controlled trials were identified. Two retrospective two-arm studies were included comparing long-term surveillance imaging with clinical surveillance and were each rated as having moderate risk of bias. Each study included heterogeneous populations with variable risk profiles and imaging surveillance protocols. Both studies investigated the impact of long-term surveillance imaging on overall survival and came to a different conclusion with one study reporting a survival benefit for long-term surveillance imaging with FDG PET/CT in patients with stage III or IV disease or an oropharyngeal primary tumor and the other study demonstrating no survival benefit.
LIMITATIONS
Limited heterogeneous retrospective data available precludes definitive conclusions on the impact of long-term surveillance imaging in head and neck squamous cell carcinoma.
CONCLUSIONS
There is insufficient quality evidence regarding the impact of long-term surveillance imaging on survival in patients treated definitively for head and neck squamous cell carcinoma. There is a lack of standardized definition of long-term surveillance, variable surveillance protocols, and inconsistencies in results reporting, underscoring the need for a prospective multi-center registry assessing outcomes.

Archives of Physical Medicine and... Jun 2024To examine the evidence regarding FES-cycling's physiological and clinical effects. (Review)
Review
OBJECTIVE
To examine the evidence regarding FES-cycling's physiological and clinical effects.
DATA SOURCES
The study was conducted in accordance with PRISMA. PubMed, EMBASE, Cochrane Review, CINAHL, Scopus, Sport Discus, and Web of Science databases were used.
STUDY SELECTION
Randomized controlled trials involving FES-cycling were included. Studies that didn't involve FES-cycling in the intervention group or without the control group were excluded. Two reviewers screened titles and abstracts and then conducted a blinded full-text evaluation. A third reviewer resolved discrepancies.
DATA EXTRACTION
Meta-analysis was performed using inverse variance for continuous data with effect measured by mean difference and random effects analysis model. A 95% confidence interval was adopted. The significance level was set at p<.05, and trends were declared at p=.05 to ≤ .10. The I method was used for heterogeneity analysis. The minimal clinically important difference was calculated. Methodological quality was assessed by the risk-of-bias tool for randomized trials. The GRADE method was used for the quality of the evidence analysis.
RESULTS
A total of 52 studies were included. Metabolic, cardiocirculatory, ventilatory, and peripheral muscle oxygen extraction variables presented statistical (p<.05) and clinically important differences favoring FES-cycling, with moderate to high certainty of evidence. It also presented statistical (p<.05) and clinically important improvement in cardiorespiratory fitness, leg and total body lean mass, power, physical fitness in intensive care (moderate to high certainty of evidence), and torque (low certainty of evidence). It presented a trend (p=.05 to ≤.10) of improvement in muscle volume, spasticity, and mobility (low to moderate certainty of evidence). It showed no difference (p>.10) in six-minute walking distance, muscle cross-sectional area, bone density, and length of ICU stay (low to moderate certainty of evidence).
CONCLUSIONS
FES-cycling exercise is a more intense stimulus modality than other comparative therapeutic modalities and presented clinically important improvement in several clinical outcomes.

Initial Oxygen Concentration for the Resuscitation of Infants Born at Less Than 32 Weeks' Gestation: A Systematic Review and Individual Participant Data Network Meta-Analysis.
IMPORTANCE
Resuscitation with lower fractional inspired oxygen (FiO2) reduces mortality in term and near-term infants but the impact of this practice on very preterm infants is unclear.
OBJECTIVE
To evaluate the relative effectiveness of initial FiO2 on reducing mortality, severe morbidities, and oxygen saturations (SpO2) in preterm infants born at less than 32 weeks' gestation using network meta-analysis (NMA) of individual participant data (IPD).
DATA SOURCES
MEDLINE, Embase, CENTRAL, CINAHL, ClinicalTrials.gov, and WHO ICTRP from 1980 to October 10, 2023.
STUDY SELECTION
Eligible studies were randomized clinical trials enrolling infants born at less than 32 weeks' gestation comparing at least 2 initial oxygen concentrations for delivery room resuscitation, defined as either low (≤0.3), intermediate (0.5-0.65), or high (≥0.90) FiO2.
DATA EXTRACTION AND SYNTHESIS
Investigators from eligible studies were invited to provide IPD. Data were processed and checked for quality and integrity. One-stage contrast-based bayesian IPD-NMA was performed with noninformative priors and random effects and adjusted for key covariates.
MAIN OUTCOMES AND MEASURES
The primary outcome was all-cause mortality at hospital discharge. Secondary outcomes were morbidities of prematurity and SpO2 at 5 minutes.
RESULTS
IPD were provided for 1055 infants from 12 of the 13 eligible studies (2005-2019). Resuscitation with high (≥0.90) initial FiO2 was associated with significantly reduced mortality compared to low (≤0.3) (odds ratio [OR], 0.45; 95% credible interval [CrI], 0.23-0.86; low certainty) and intermediate (0.5-0.65) FiO2 (OR, 0.34; 95% CrI, 0.11-0.99; very low certainty). High initial FiO2 had a 97% probability of ranking first to reduce mortality. The effects on other morbidities were inconclusive.
CONCLUSIONS AND RELEVANCE
High initial FiO2 (≥0.90) may be associated with reduced mortality in preterm infants born at less than 32 weeks' gestation compared to low initial FiO2 (low certainty). High initial FiO2 is possibly associated with reduced mortality compared to intermediate initial FiO2 (very low certainty) but more evidence is required.

Resuscitation Plus Sep 2024To examine speed and accuracy of newborn heart rate measurement by various assessment methods employed at birth. (Review)
Review
AIM
To examine speed and accuracy of newborn heart rate measurement by various assessment methods employed at birth.
METHODS
A search of Medline, SCOPUS, CINAHL and Cochrane was conducted between January 1, 1946, to until August 16, 2023. (CRD 42021283364) Study selection was based on predetermined criteria. Reviewers independently extracted data, appraised risk of bias and assessed certainty of evidence.
RESULTS
Pulse oximetry is slower and less precise than ECG for heart rate assessment. Both auscultation and palpation are imprecise for heart rate assessment. Other devices such as digital stethoscope, Doppler ultrasound, an ECG device using dry electrodes incorporated in a belt, photoplethysmography and electromyography are studied in small numbers of newborns and data are not available for extremely preterm or bradycardic newborns receiving resuscitation. Digital stethoscope is fast and accurate. Doppler ultrasound and dry electrode ECG in a belt are fast, accurate and precise when compared to conventional ECG with gel adhesive electrodes.
LIMITATIONS
Certainty of evidence was low or very low for most comparisons.
CONCLUSION
If resources permit, ECG should be used for fast and accurate heart rate assessment at birth. Pulse oximetry and auscultation may be reasonable alternatives but have limitations. Digital stethoscope, doppler ultrasound and dry electrode ECG show promise but need further study.

Comparative Diagnostic Accuracy of Computed Tomography Scan versus Magnetic Resonance Imaging in the Emergency Department for the Evaluation of Dizziness: A Systematic Review.
Both computed tomography (CT) and magnetic resonance imaging (MRI) play significant roles in assessing patients with dizziness. However, understanding the comparative capabilities of these imaging methods in detecting pathological causes is crucial for determining the most suitable modality. This review aims to evaluate the diagnostic accuracy and clinical utility of MRI and CT scans in managing patients with acute dizziness in the emergency department. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a comprehensive search in various databases (PubMed, Google Scholar, Cochrane library, British Medical Journals, and ScienceDirect) from 2010 to 2023. We used the QUADAS-2 tool to assess bias risk, considering MRI as the reference standard and CT scan as the index test. The final analysis included six studies, with 3,993 patients (48% male, 52% female; average age: 56.7 years). Three studies were of high quality, two of medium quality, and one of low quality. Central ischemia was the predominant diagnosis for dizziness. MRI demonstrated higher diagnostic efficacy for stroke compared with CT scans, while mixed results were observed for other multiple diseases when both MRI and CT scans were used. MRI outperforms CT scans in diagnosing dizziness-related strokes. However, for other causes of dizziness, there is no significant difference between these techniques. Nevertheless, it is crucial to acknowledge the limitations associated with MRI. Consequently, to address these concerns, the selection of an imaging technique should be tailored to the individual based on factors such as their clinical presentation, comorbidities, and socioeconomic circumstances.

Review
Although abundant literature is currently available on the use of deep learning for breast cancer detection in mammography, the quality of such literature is widely variable. To evaluate published literature on breast cancer detection in mammography for reproducibility and to ascertain best practices for model design. The PubMed and Scopus databases were searched to identify records that described the use of deep learning to detect lesions or classify images into cancer or noncancer. A modification of Quality Assessment of Diagnostic Accuracy Studies (mQUADAS-2) tool was developed for this review and was applied to the included studies. Results of reported studies (area under curve [AUC] of receiver operator curve [ROC] curve, sensitivity, specificity) were recorded. A total of 12,123 records were screened, of which 107 fit the inclusion criteria. Training and test datasets, key idea behind model architecture, and results were recorded for these studies. Based on mQUADAS-2 assessment, 103 studies had high risk of bias due to nonrepresentative patient selection. Four studies were of adequate quality, of which three trained their own model, and one used a commercial network. Ensemble models were used in two of these. Common strategies used for model training included patch classifiers, image classification networks (ResNet in 67%), and object detection networks (RetinaNet in 67%). The highest reported AUC was 0.927 ± 0.008 on a screening dataset, while it reached 0.945 (0.919-0.968) on an enriched subset. Higher values of AUC (0.955) and specificity (98.5%) were reached when combined radiologist and Artificial Intelligence readings were used than either of them alone. None of the studies provided explainability beyond localization accuracy. None of the studies have studied interaction between AI and radiologist in a real world setting. While deep learning holds much promise in mammography interpretation, evaluation in a reproducible clinical setting and explainable networks are the need of the hour.

Review
BACKGROUND
Investment in mobile devices to support primary or elementary education is increasing and must be informed by robust evidence to demonstrate impact. This systematic review of randomised controlled trials sought to identify the overall impact of mobile devices to support literacy and numeracy outcomes in mainstream primary classrooms.
OBJECTIVES
The aim of this systematic review was to understand how mobile devices are used in primary/elementary education around the world, and in particular, determine how activities undertaken using mobile devices in the primary classroom might impact literacy and numeracy attainment for the pupils involved. Within this context, mobile devices are defined as tablets (including iPads and other branded devices), smartphones (usually those with a touchscreen interface and internet connectivity) and handheld games consoles (again usually with touchscreen and internet-enabled). The interventions of interest were those aimed at improving literacy and/or numeracy for children aged 4-12 within the primary/elementary school (or equivalent) classroom.Specifically, the review aimed to answer the following research questions: -What is the effect of mobile device integration in the primary school classroom on children's literacy and numeracy outcomes?-Are there specific devices which are more effective in supporting literacy and numeracy? (Tablets, smartphones, or handheld games consoles)-Are there specific classroom integration activities which moderate effectiveness in supporting literacy and numeracy?-Are there specific groups of children for whom mobile devices are more effective in supporting literacy and numeracy? (Across age group and gender).-Do the benefits of mobile devices for learning last for any time beyond the study?-What is the quality of available evidence on the use of mobile devices in primary/elementary education, and where is further research needed in this regard? An Expert Advisory Group supported the review process at key stages to ensure relevance to current practice.
SEARCH METHODS
The search strategy was designed to retrieve both published and unpublished literature, and incorporated relevant journal and other databases with a focus on education and social sciences. Robust electronic database searches were undertaken (12 databases, including APA PsychInfo, Web of Science, ERIC, British Education Index and others, and relevant government and other websites), as well as a hand-search of relevant journals and conference proceedings. Contact was also made with prominent authors in the field to identify any ongoing or unpublished research. All searches and author contact took place between October and November 2020. The review team acknowledges that new studies will likely have emerged since and are not captured at this time. A further update to the review in the future is important and would build on the evidence reflected here.
SELECTION CRITERIA
The review included children within mainstream primary/elementary/kindergarten education settings in any country (aged 4-12), and interventions or activities initiated within the primary school classroom (or global equivalent) that used mobile devices (including tablets, smartphones, or hand-held gaming devices) to intentionally support literacy or numeracy learning. In terms of study design, only Randomised Controlled Trials were included in the review.
DATA COLLECTION AND ANALYSIS
A total of 668 references were identified through a robust search strategy including published and unpublished literature. Following duplicate screening, 18 relevant studies, including 11,126 participants, 14 unique interventions, and 46 relevant outcome measures were synthesised using Robust Variance Estimation and a random effects meta-analysis model. Risk of Bias assessment was undertaken by three reviewers using the ROB2 tool to assess the quality of studies, with 13 studies rated as having some concerns, and 5 as having high risk of bias. Qualitative data was also extracted and analysed in relation to the types of interventions included to allow a comparison of the key elements of each.
MAIN RESULTS
A positive, statistically significant combined effect was found (Cohen's = 0.24, CI 0.0707 to 0.409, < 0.01), demonstrating that in the studies and interventions included, children undertaking maths or literacy interventions using mobile devices achieved higher numeracy or literacy outcomes than those using an alternative device (e.g., a laptop or desktop computer) or no device (class activities as usual). However these results should be interpreted with caution given the risk of bias assessment noted above (5 studies rated high risk of bias and 13 rated as having some concerns). As the interventions and classroom circumstances differed quite widely, further research is needed to understand any potential impact more fully.Sensitivity analysis aimed to identify moderating factors including age or gender, screen size, frequency/dosage of intervention exposure, and programme implementation features/activities (based on Puentedura's [2009] SAMR model of technology integration). There were too few studies identified to support quantitative analysis of sufficient power to draw robust conclusions on moderating factors, and insufficient data to determine impact beyond immediate post-test period. Sensitivty analysis was also undertaken to exclude the five studies identified as having a high risk of bias, to identify any impact they may have on overall findings.
AUTHORS' CONCLUSIONS
Overall, this review demonstrates that for the specific interventions and studies included, mobile device use in the classroom led to a significant, positive effect on literacy and numeracy outcomes for the children involved, bringing positive implications for their continued use in primary education. However given the concerns on risk of bias assessment reported above, the differing circumstances, interventions and treatment conditions and intensities, the findings must be interpreted with caution. The review also supports the need for further robust research to better understand what works, under what circumstances, and for whom, in the use of mobile devices to support learning.
