Review
Increasing air pollution is common around the world, but the impacts of outdoor air pollution exposure on atopic dermatitis (AD) are unclear. We synthesized the current global epidemiologic evidence for air pollution exposure and associated medical visits for AD among adults and children. This review followed PRISMA guidelines, and searches were conducted on PubMed, MEDLINE, Web of Science and EMBASE databases. The searches yielded 390 studies, and after screening, 18 studies around the world assessing at least 5,197,643 medical visits for AD in total were included for the final analysis. We found that exposure to particulate matter ≤2.5 μm in diameter (PM ) [(10/11) of studies], particulate matter ≤10 μm in diameter (PM ) (11/13), nitrogen dioxide (NO ) (12/14) and sulfur dioxide (SO ) (10/13) was positively associated with AD visits. Results were equivocal for ozone [(4/8) of studies reported positive association] and limited for carbon monoxide [(1/4) of studies reported positive association]. When stratifying results by patient age, patient sex and season, we found that the associations with particulate matter, NO and O may be affected by temperature. Exposure to selected air pollutants is associated with AD visits, and increasingly poor worldwide air quality may increase global healthcare use for AD.

Meta-Analysis Review
Environmental pollutants are ubiquitous in our environmental media, resulting in detrimental impacts on both humans and the environment. An evidence-based review, particularly a systematic review and meta-analysis, performs a crucial function in assessing the pollution status of pollutants in environmental media at national and global scales. We selected and thoroughly investigated 76 papers focusing on systematic reviews and meta-analyses of contaminants in environmental media. The need to broaden the scope of studies was observed with an increase in the total number of publications, and there were greater focuses on food safety, water pollution, biological pollution, and environmental risks. Furthermore, this review outlined the fundamental procedures involved in a systematic review and meta-analysis, including literature searching, screening of articles, study quality analysis, data extraction and synthesis, and meta-analysis. A meta-analysis typically comprises fixed- and/or random-effects meta-analysis, identifying and measuring heterogeneity, sensitivity analysis, publication bias, subgroup analysis, and meta-regression. We specifically explored the application of meta-analysis to assess the presence of contaminants in environmental media based on two different pollutant categories, namely, non-biological and biological pollutants. The mean value is commonly utilized to assess the pooled concentration of non-biological pollutants, while the prevalence serves as the effect size of biological pollutants. Additionally, we summarized the innovative applications, frequent misuses, and problems encountered in systematic reviews and meta-analyses. Finally, we proposed several suggestions for future research endeavors.

Meta-Analysis Review
Preterm birth (PTB) is considered as a public health problem and one of the main risk factors related to the global disease burden. The purpose of this study aims to explore the influence of exposure to major air pollutants at different pregnancies on PTB. The relationship between air pollutants and PTB in China was collected from cohort studies and case-control studies published before 30 April 2022. Meta-analysis was carried out with STATA 15.0 software. A total of 2,115 papers were retrieved, of which 18 papers met the inclusion criteria. The comprehensive effect of pollutant exposure and PTB were calculated. PM during entire pregnancy and O exposure during third trimester were positively associated with preterm birth. Every 10 μg/m increase in the average concentration of PM during the whole pregnancy will increase the risk of premature delivery by 4%, and every 10 μg/m increase in the average concentration of O in the third trimester will increase the risk of premature delivery by 1%. Exposure to PM entire prenatal pregnancy and O in third trimester is associated with an increased risk of preterm birth occurrence.

Review
BACKGROUND
Although several risk factors of kidney cancer have already been well-addressed, many remain underappreciated, such as chronic exposure to air pollution. This systematic review and meta-analysis aims to assess the association between air pollutant exposure and the risk of kidney cancer.
METHODS
With an exhaustive search equation including keywords related to air pollution and kidney cancer on EMBASE, PubMed, Web of science, Cochrane Library and CINAHL database, we identified all relevant articles published before March 23rd, 2023 (Prospero registration number: CRD42020187956). Using random-effects meta-analysis, we present pooled hazard ratios (with their respective 95% confidence interval) associated with a 10 µg/m increase in each pollutant level. Heterogeneity was quantified by the I statistic. Risks of methodological and publication bias were also both assessed using appropriate tools.
RESULTS
Of the 1919 records identified, our review included 19 articles (13 cohort, 5 registry-based and 1 case-control studies), of which 9 were suitable for the meta-analysis. We found a significantly increased risk of kidney cancer incidence for a 10 μg/m elevation of both particulate matter of less than 10 µm (PM) (HR = 1.29 [1.10; 1.51], I = 0%, p = 0.002) and nitrogen dioxide (NO) (HR = 1.10 [1.03; 1.18], I = 20%, p = 0.004). Secondary analyses also suggest an increased risk of kidney cancer-related morbidity-mortality associated with PM exposure.
CONCLUSIONS
Overall, our findings suggest a potential association between exposure to increased levels of PM and NO and the risk of kidney cancer. These results should nonetheless be interpreted with caution due to the limited number of included studies and their significant risk of methodological bias.

Review
Airway suctioning is routinely performed in the majority of care circumstances, including acute care, subacute care, home-based settings, and long-term care. Using an artificial airway to suction the patient allows for the mobilization and evacuation of secretions. When a patient can't independently remove all of the secretions from their respiratory tract, suction is used. This can occur when the body produces excessive secretion or it is not eliminated quickly enough, causing the respiratory system's upper and lower respiratory secretions to accumulate. Airway blockage and inadequate breathing may result from this. Ultimately, this leads to a shortage of oxygen and carbon dioxide from the air, both of which are necessary for ideal cellular activity. Artificial airway suctioning is one of the most crucial components of airway care and a core competency for medical professionals trying to ensure airway patency. Artificial airway suctioning is a standard treatment carried out every day globally and is frequently done in both outpatient and inpatient patients. Therefore, specialists must know the safest and most efficient ways to perform surgery and any potential side effects. In ventilated infants and children, the removal of obstructive secretions by endotracheal suctioning is frequently done. It is unknown how suctioning affects the mechanics of breathing. This study used a prospective observational clinical design to examine the immediate impact of airway resistance in endotracheal suctioning, tidal volume, and dynamic lung regulation in mechanically ventilated adult patients and mechanically ventilated pediatric patients. The preparation, process, and indications for intraoperative fusion treatment in various circumstances are covered in this systematic review.

Review
BACKGROUND
eHealth monitoring technologies offer opportunities to more objectively assess symptoms when they appear in daily life. Asthma is the most common chronic disease in childhood with an episodic course, requiring close follow-up of pediatric asthma control to identify disease deterioration, prevent exacerbations, and enhance quality of life. eHealth technologies in pediatric asthma care show promising results regarding feasibility, acceptability, and asthma-related health outcomes. However, broad systematic evaluations of eHealth technologies in pediatric asthma are lacking.
OBJECTIVE
The objective of this scoping review was to identify the types and applications of eHealth technologies for monitoring and treatment in pediatric asthma and explore which monitoring domains show the most relevance or potential for future research.
METHODS
A scoping review was conducted using the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. A systematic and comprehensive search was performed on English papers that investigated the development, validation, or application of eHealth technologies for home monitoring or treatment of pediatric asthma in the following databases: PubMed, Cochrane Library, IEEE, Scopus, CINAHL, PsycINFO, and ACM Digital Library. Two authors independently assessed eligibility and extracted data. Data were presented by a descriptive analysis of characteristics and a narrative report for each eHealth domain.
RESULTS
The review included 370 manuscripts. The following 10 monitoring domains were identified: air quality, airway inflammation markers, lung function, physical activity, sleep, audiovisual, other physiological measurements, questionnaires, medication monitoring, and digital environment (ie, digital platforms, applications, websites, and software tools to monitor or support monitoring). Rising numbers of studies were seen, and the numbers accelerated in the last few years throughout most domains, especially medication monitoring and digital environment. Limited studies (35/370, 9.5%) of multiparameter monitoring strategies, using three or more domains, were found. The number of monitoring validation studies remained stable, while development and intervention studies increased. Intervention outcomes seemed to indicate the noninferiority and potential superiority of eHealth monitoring in pediatric asthma.
CONCLUSIONS
This systematic scoping review provides a unique overview of eHealth pediatric asthma monitoring studies, and it revealed that eHealth research takes place throughout different monitoring domains using different approaches. The outcomes of the review showed the potency for efficacy of most monitoring domains (especially the domains of medication monitoring, lung function, and digital environment). Future studies could focus on modifying potentially relevant hospital-based diagnostics for the home setting to investigate potential beneficial effects and focus on combining home-monitoring domains to facilitate multiparameter decision-making and personalized clinical decision support.

Review
BACKGROUND
The Neonatal Task Force of the International Liaison Committee on Resuscitation (ILCOR) makes practice recommendations for the care of newborn infants in the delivery room (DR). ILCOR recommends that all infants who are gasping, apnoeic, or bradycardic (heart rate < 100 per minute) should be given positive pressure ventilation (PPV) with a manual ventilation device (T-piece, self-inflating bag, or flow-inflating bag) via an interface. The most commonly used interface is a face mask that encircles the infant's nose and mouth. However, gas leak and airway obstruction are common during face mask PPV. Nasal interfaces (single and binasal prongs (long or short), or nasal masks) and laryngeal mask airways (LMAs) may also be used to deliver PPV to newborns in the DR, and may be more effective than face masks.
OBJECTIVES
To determine whether newborn infants receiving PPV in the delivery room with a nasal interface compared to a face mask, laryngeal mask airway (LMA), or another type of nasal interface have reduced mortality and morbidity. To assess whether safety and efficacy of the nasal interface differs according to gestational age or ventilation device.
SEARCH METHODS
Searches were conducted in September 2022 in CENTRAL, MEDLINE, Embase, Epistemonikos, and two trial registries. We searched conference abstracts and checked the reference lists of included trials and related systematic reviews identified through the search.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) and quasi-RCT's that compared the use of nasal interfaces to other interfaces (face masks, LMAs, or one nasal interface to another) to deliver PPV to newborn infants in the DR.
DATA COLLECTION AND ANALYSIS
Each review author independently evaluated the search results against the selection criteria, screened retrieved records, extracted data, and appraised the risk of bias. If they were study authors, they did not participate in the selection, risk of bias assessment, or data extraction related to the study. In such instances, the study was independently assessed by other review authors. We contacted trial investigators to obtain additional information. We completed data analysis according to the standards of Cochrane Neonatal, using risk ratio (RR) and 95% confidence Intervals (CI) to measure the effect of the different interfaces. We used fixed-effect models and the GRADE approach to assess the certainty of the evidence.
MAIN RESULTS
We included five trials, in which 1406 infants participated. They were conducted in 13 neonatal centres across Europe and Australia. Each of these trials compared a nasal interface to a face mask for the delivery of respiratory support to newborn infants in the DR. Potential sources of bias were a lack of blinding to treatment allocation of the caregivers and investigators in all trials. The evidence suggests that resuscitation with a nasal interface in the DR, compared with a face mask, may have little to no effect on reducing death before discharge (typical risk ratio (RR) 0.72, 95% CI 0.47 to 1.13; 3 studies, 1124 infants; low-certainty evidence). Resuscitation with a nasal interface may reduce the rate of intubation in the DR, but the evidence is very uncertain (RR 0.68, 95% CI 0.54 to 0.85; 5 studies, 1406 infants; very low-certainty evidence). The evidence is very uncertain for the rate of intubation within 24 hours of birth (RR 0.97, 95% CI 0.85 to 1.09; 3 studies, 749 infants; very low-certainty evidence), endotracheal intubation outside the DR during hospitalisation (RR 1.15, 95% CI 0.93 to 1.42; 1 study, 144 infants; very low-certainty evidence) and cranial ultrasound abnormalities (intraventricular haemorrhage (IVH) grade ≥ 3, or periventricular leukomalacia; RR 0.94, 95% CI 0.55 to 1.61; 3 studies, 749 infants; very low-certainty evidence). Resuscitation with a nasal interface in the DR, compared with a face mask, may have little to no effect on the incidence of air leaks (RR 1.09, 95% CI 0.85 to 1.09; 2 studies, 507 infants; low-certainty evidence), or the need for supplemental oxygen at 36 weeks' corrected gestational age (RR 1.06, 95% CI 0.8 to 1.40; 2 studies, 507 infants; low-certainty evidence). We identified one ongoing study, which compares a nasal mask to a face mask to deliver PPV to infants in the DR. We did not identify any completed trials that compared nasal interfaces to LMAs or one nasal interface to another.
AUTHORS' CONCLUSIONS
Nasal interfaces were found to offer comparable efficacy to face masks (low- to very low-certainty evidence), supporting resuscitation guidelines that state that nasal interfaces are a comparable alternative to face masks for providing respiratory support in the DR. Resuscitation with a nasal interface may reduce the rate of intubation in the DR when compared with a face mask. However, the evidence is very uncertain. This uncertainty is attributed to the use of a new ventilation system in the nasal interface group in two of the five trials. As such, it is not possible to differentiate separate, specific effects related to the ventilation device or to the interface in these studies.

Review
UNLABELLED
Gaseous emissions have contributed to global warming, an increase in the frequency of extreme weather events and poorer air quality. The associated health impacts have been well reported in temperate regions. In Singapore, key climate change adaptation measures and activities include coastal and flood protection, and mitigating heat impacts. We systematically reviewed studies examining climate variability and air quality with population health in Singapore, a tropical city-state in South-East Asia (SEA), with the aim to identify evidence gaps for policymakers. We included 14 studies with respiratory illnesses, cardiovascular outcomes, foodborne disease and dengue. Absolute humidity (3 studies) and rainfall (2 studies) were positively associated with adverse health. Extreme heat (2 studies) was inversely associated with adverse health. The effects of mean ambient temperature and relative humidity on adverse health were inconsistent. Nitrogen dioxide and ozone were positively associated with adverse health. Climate variability and air quality may have disease-specific, differing directions of effect in Singapore. Additional high quality studies are required to strengthen the evidence for policymaking. Research on effective climate action advocacy and adaptation measures for community activities should be strengthened.

Meta-Analysis Review
BACKGROUND
The COVID-19 pandemic presents unprecedented challenge for global public health systems and exacerbates existing health disparities. Epidemiological evidence suggested a potential linkage between particulate and gaseous pollutants and COVID-19 mortality. We aimed to summarize the overall risk of COVID-19 mortality associated with ambient air pollutants over the short- and long-term.
METHODS
For the systematic review and meta-analysis, we searched five databases for studies evaluating the risk of COVID-19 mortality from exposure to air pollution. Inclusion of articles was assessed independently on the basis of research topic and availability of effect estimates. The risk estimates (relative risk) for each pollutant were pooled with a random-effect model. Potential heterogeneity was explored by subgroup analysis. Funnel plots and trim-and-fill methods were employed to assess and adjust for publication bias.
FINDINGS
The systematic review retrieved 2059 records, and finally included 43 original studies. PM (RR: 1.71, 95 % CI: 1.40-2.08, per 10 μg/m increase), NO (RR: 1.33, 1.07-1.65, per 10 ppb increase) and O (RR: 1.61, 1.00-2.57, per 10 ppb increase) were positively associated with COVID-19 mortality for long-term exposures. Accordingly, a higher risk of COVID-19 mortality was associated with PM (1.05, 1.02-1.08), PM (1.05, 1.01-1.08), and NO (1.40, 1.04-1.90) for short-term exposures. There was some heterogeneity across subgroups of income level and geographical areas.
CONCLUSION
Both long-term and short-term exposures to ambient air pollution may increase the risk of COVID-19 mortality. Future studies utilizing individual-level information on demographics, exposures, outcome ascertainment and confounders are warranted to improve the accuracy of estimates.

Meta-Analysis Review
Congenital heart diseases (CHDs) are a prevalent form of congenital malformations in newborns. Although previous studies have explored the association between maternal exposure to ambient air pollution and congenital anomalies in offspring, the results still remain ambiguous. To fill the knowledge gap, we performed a systematic review and meta-analysis of existing literature. A comprehensive search of the literature was conducted in PubMed, Embase, and Web of Science until August 12, 2022. We analyzed the relationship between air pollution and multiple CHDs using either a fixed-effect model or a random-effects model. Summary risk estimates of pollution-outcome pairs were calculated based on (i) risk per increment of concentration and (ii) risk at high versus low exposure levels. Additionally, we performed leave-one-out analyses and used funnel plots to assess the potential publication bias. A total of 32 studies were included and four studies utilizing distributed lag nonlinear models (DLNM) models were added to our retrospective review. In the continuous exposure meta-analysis, there were statistically significant negative associations between sulfur dioxide (SO) and transposition of the great arteries (OR = 0.96; 95 % CI: 0.93-0.99), pulmonary artery and valve defect (OR = 0.90; 95 % CI: 0.83-0.97), and ventricular septal defect (OR = 0.95; 95 % CI: 0.91-0.99). High versus low SO exposure was associated with a decreased risk of tetralogy of Fallot [OR = 0.83; 95 % CI: 0.69-0.99]. However, carbon monoxide (CO) increased risk estimates for tetralogy of Fallot in both continuous exposure (OR = 2.25; 95 % CI: 1.42-3.56) and high-low exposure (OR = 1.24; 95 % CI: 1.01-1.54). Particulate matter 10 (PM) statistically significant increased in the risk of overall CHD with odds ratios of 1.03 (95 % CI: 1.01-1.05) and 1.04 (95 % CI: 1.00-1.09) in continuous and categorical exposure analysis, respectively. These findings provide potential evidence for the association between maternal air pollution exposure and CHDs.
