Meta-Analysis Review
Background Pulmonary arterial end-diastolic forward flow (EDFF) following repaired tetralogy of Fallot has been thought to represent right ventricular (RV) restrictive physiology, but is not fully understood. This systematic review and meta-analysis sought to clarify its physiological and clinical correlates, and to define a framework for understanding EDFF and RV restrictive physiology. Methods and Results PubMed/MEDLINE, Embase, Scopus, and reference lists of relevant articles were searched for observational studies published before March 2021. Random-effects meta-analysis was performed to identify factors associated with EDFF. Forty-two individual studies published between 1995 and 2021, including a total of 2651 participants (1132 with EDFF; 1519 with no EDFF), met eligibility criteria. The pooled estimated prevalence of EDFF among patients with repaired tetralogy of Fallot was 46.5% (95% CI, 41.6%-51.3%). Among patients with EDFF, the use of a transannular patch was significantly more common, and their stay in the intensive care unit was longer. EDFF was associated with greater RV indexed volumes and mass, as well as smaller E-wave velocity at the tricuspid valve. Finally, pulmonary regurgitation fraction was greater in patients with EDFF, and moderate to severe pulmonary regurgitation was more common in this population. Conclusions EDFF is associated with dilated, hypertrophied RVs and longstanding pulmonary regurgitation. Although several studies have defined RV restrictive physiology as the presence of EDFF, our study found no clear indicators of poor RV compliance in patients with EDFF, suggesting that EDFF may have multiple causes and might not be the precise equivalent of RV restrictive physiology.

Review
INTRODUCTION
The survivability of mass casualties exposed to a chemical attack is dependent on clinical knowledge, evidence-based practice, as well as protection and decontamination capabilities. The aim of this systematic review was to identify the knowledge gaps that relate to an efficient extraction and care of mass casualties caused by exposure to chemicals.
METHODS
This systematic review was conducted from November 2018 through September 2020 in compliance with Cochrane guidelines. Five databases were used (MEDLINE, Web of Science Core Collection, Embase, Cochrane, and CINAHL) to retrieve studies describing interventions performed to treat victims of chemical attacks (protection, decontamination, and treatment). The outcomes were patient's health condition leading to his/her stabilization (primary) and death (secondary) due to interventions applied (medical, protection, and decontamination).
RESULTS
Of the 2,301 papers found through the search strategy, only four publications met the eligibility criteria. According to these studies, the confirmed chemical poisoning cases in acute settings resulting from the attacks in Matsumoto (1994), Tokyo (1995), and Damascus (2014) accounted for 1,333 casualties including 11 deaths. No study reported comprehensive prehospital clinical data in acute settings. No mention was made of the integration of specialized capabilities in medical interventions such as personal protective equipment (PPE) and decontamination to prevent a secondary exposure. Unfortunately, it was not possible to perform the planned meta-analysis.
CONCLUSIONS
This study demonstrated gaps in clinical knowledge application regarding the medical extraction of casualties exposed during a chemical attack. Further research is required to optimize clinical practice integrating mixed capabilities (protection and decontamination) for the patient and medical staff.

Meta-Analysis Review
BACKGROUND
Prehabilitation is a promising method to enhance postoperative recovery, especially in patients suffering from cancer. Particularly during times of social distancing, providing home-based programmes may have become a suitable solution to increase compliance and effectiveness.
METHODS
In line with the PRISMA guidelines, a systematic review was conducted including trials that investigated the effect of home-based prehabilitation (HBP) in patients undergoing surgery for cancer. The primary outcome was postoperative functional capacity (6 min walk test, 6MWT). Secondary outcomes were postoperative complications and compliance.
RESULTS
Five randomized controlled trials were included with 351 patients undergoing surgery for colorectal cancer, oesophagogastric cancer, bladder cancer and non-small cell lung cancer. Three studies presented results of significant progress after eight weeks. The meta-analysis showed a significant improvement of the 6MWT in the prehabilitation group compared to the control group preoperatively (MD 35.06; 95% CI 11.58 to 58.54; p = .003) and eight weeks postoperatively (MD 44.91; 95% CI 6.04 to 83.79; p = .02) compared to baseline. Compliance rate varied from 63% to 83% with no significant difference between prehabilitation and control groups. These data must be interpreted with caution because of a high amount of heterogeneity and small sample sizes.
DISCUSSION
In conclusion, HBP may enhance overall functional capacity of patients receiving oncological surgery compared to standard of care. This could be a promising alternative to hospital-based prehabilitation regarding the current pandemic and further digitalization in the future. In order to increase accessibility and effectiveness of prehabilitation, home-based solutions should be further investigated.

A systematic review was conducted to investigate the effect of respiratory physiotherapy on mortality, quality of life, functional recovery, intensive care length of stay, duration of ventilation, oxygenation, secretion clearance, and pulmonary mechanics for invasively ventilated adults with pneumonia. Five databases were searched for randomized trials published between January 1995 and November 2018. Study quality was assessed using a standardized Joanna Briggs Institute critical appraisal tool, and Review Manager software was used to pool the studies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the level of certainty of the evidence. A total of 14 studies of moderate quality included 251 subjects with pneumonia. Eight studies were pooled for meta-analysis. Interventions that increased inspiratory volume appeared to benefit secretion clearance by nearly 2 grams (mean difference [MD] 1.97; 95% CI: 0.80, 3.14; very low GRADE evidence) and increase static lung compliance immediately after treatment by more than 5 millilitres/centimetre H0 (MD 5.40 mL/cm HO; 95% CI: 2.37, 8.43; very low GRADE evidence) or by more than 6 millilitres/centimetre HO after a 20- to 30-minute delay (MD 6.86 mL/cm HO; 95% CI: 2.86, 10.86; very low GRADE evidence). No adverse events were found. Respiratory physiotherapy that increases tidal volume may benefit secretion clearance and lung compliance in invasively ventilated adults with pneumonia, but its impact on other outcomes, including mortality, length of stay, and other patient-centred outcomes, is unclear, and further research is required.

Acute hypoxia exposure is associated with an elevation of pulmonary artery pressure (PAP), resulting in an increased hemodynamic load on the right ventricle (RV). In addition, hypoxia may exert direct effects on the RV. However, the RV responses to such challenges are not fully characterized. The aim of this systematic review was to describe the effects of acute hypoxia on the RV in healthy lowland adults. We systematically reviewed PubMed and Web of Science and article references from 2005 until May 2021 for prospective studies evaluating echocardiographic RV function and morphology in healthy lowland adults at sea level and upon exposure to simulated altitude or high-altitude. We included 37 studies in this systematic review, 12 of which used simulated altitude and 25 were conducted in high-altitude field conditions. Eligible studies reported at least one of the RV variables, which were all based on transthoracic echocardiography assessing RV systolic and diastolic function and RV morphology. The design of these studies significantly differed in terms of mode of ascent to high-altitude, altitude level, duration of high-altitude stay, and timing of measurements. In the majority of the studies, echocardiographic examinations were performed within the first 10 days of high-altitude induction. Studies also differed widely by selectively reporting only a part of multiple RV parameters. Despite consistent increase in PAP documented in all studies, reports on the changes of RV function and morphology greatly differed between studies. This systematic review revealed that the study reports on the effects of acute hypoxia on the RV are controversial and inconclusive. This may be the result of significantly different study designs, non-compliance with international guidelines on RV function assessment and limited statistical power due to small sample sizes. Moreover, the potential impact of other factors such as gender, age, ethnicity, physical activity, mode of ascent and environmental factors such as temperature and humidity on RV responses to hypoxia remained unexplored. Thus, this comprehensive overview will promote reproducible research with improved study designs and methods for the future large-scale prospective studies, which eventually may provide important insights into the RV response to acute hypoxia exposure.

Review
Associated factors, assessment, management, and outcomes of patients who present to the emergency department for acute exacerbation of chronic obstructive pulmonary disease: A scoping review.
OBJECTIVE
The purpose of the scoping review was to examine the extant literature for factors contributing to presentations of Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) to Emergency Departments (ED).
METHODS
The review followed Arksey and O'Malley, and Levac's frameworks supplemented with the PRISMA-ScR checklist. We searched Cochrane Library, CINAHL, JBI, and PubMed from January 1, 2008 to March 23, 2020 for inclusions. We included studies reporting ED presentations for AECOPD among adults (≥18 years). The investigation included: pre-hospital factors; ED-related assessment, management and referral practices; holistic management (i.e., interdisciplinary); patient outcomes, admission/discharge status, and readmission.
RESULTS
Forty-four studies were included. Environmental factors (e.g., air pollution, seasonal change); social determinants (e.g., poor literacy, ethnicity); and physical health (e.g., comorbidities, obesity, poor exercise capacity) contributed to ED presentation/re-presentation, and admission to hospital. Cigarette smoking was associated with hospital admission. Mortality was associated with longer-term oxygen therapy, poor exercise capacity, age, and loss of consciousness. Compliance with clinical guideline recommendations were generally low or mixed. Further, there was a lack of appropriate referral practices upon discharge.
CONCLUSIONS
While there is considerable literature on factors contributing to AECOPD admission more research is required that investigates the impact that inter-professional care models can have on the discharge planning cycles for patients with COPD who are regular presenters to an ED.

Review
Mapping of Modifiable Factors with Interdisciplinary Chronic Obstructive Pulmonary Disease (COPD) Guidelines Adherence to the Theoretical Domains Framework: A Systematic Review.
BACKGROUND
COPD guidelines non-concordance is a challenge frequently highlighted by respiratory experts. Despite the provision of comprehensive evidence-based national and international guidelines, the COPD burden to frontline healthcare services has increased in the last decade. Suboptimal guidelines concordance can be disruptive to health-related quality of life (HRQoL), hastening pulmonary function decline and surging overall morbidity and mortality. A lack of concordance with guidelines has created an escalating economic burden on health-care systems. Identifying interdisciplinary interventions to facilitate improved adherence to guidelines may significantly reduce re-admissions, enhance HRQoL amongst patients and their families, and facilitate economic efficiency.
MATERIALS AND METHODS
This review adhered to the Joanna Briggs Institute (JBI) methodology for mixed methods systematic reviews and the PRISMA ScR reporting guidelines. Two independent reviewers screened abstracts and full text articles in consonance with inclusion criteria. The convergent integrative JBI method collated quantitative, qualitative and mixed methods studies from nine databases. JBI critical appraisal tools were utilised to assess the quality of research papers. The theoretical domains framework (TDF) along with a specifically developed COPD data extraction tool were adopted as a priori to collect and collate data. Identified barriers and corresponding clinical behavioural change solutions were categorised using TDF domains and behavior change wheel (BCW) to provide future research and implementation recommendations.
RESULTS
Searches returned 1068 studies from which 37 studies were included (see Figure 1). COPD recommendations identified to be discordant with clinical practice included initiating non-invasive ventilation, over- or under-prescription of corticosteroids and antibiotics, and a lack of discharging patients with a smoking cessation plan or pulmonary rehabilitation. TDF domains with highest frequency scores were knowledge, environmental resources, and clinical behaviour regulation. Electronic order sets/digital proforma with guideline resources at point of care and easily accessible digital community referrals to target both pharmacological and non-pharmacological management appear to be a solution to improve concordance.
CONCLUSION
Implementation of consistent quality improvement intervention within hospitals for patients with COPD may exclude any implementation gap and prevent readmissions. Electronic proformas with digital referrals will assist with future evaluation audits to prioritise and target interventions to improve guidelines concordance.

Meta-Analysis Review
BACKGROUND
Adherence to therapy has been reported worldwide as a major problem, and that is particularly relevant on inhaled therapy for Asthma and Chronic Obstructive Pulmonary Disease (COPD), considering its barriers and features. We reviewed the global literature reporting the main determinants for adherence on these patients.
METHODS
Searches were made using the Cochrane Library, MEDLINE, EMBASE and ISI Web of Science databases. Analytical, observational and epidemiological studies (cohort, case-control and cross-sectional studies) were included, reporting association between any type of determinant and the adherence for inhaler therapy on Asthma or COPD. Random-effects meta-analysis were used to summarise the numerical effect estimates.
RESULTS
47 studies were included, including a total of 54.765 participants. In meta-analyses, the significant determinants of adherence to inhaled therapy were: older age [RR = 1.07 (1.03-1.10); I = 94; p < 0.0001] good disease knowledge/literacy [RR = 1.37 (1.28-1.47); I = 14; p = 0.33]; obesity [RR = 1.30 (1.12-1.50); I = 0; p = 0.37]; good cognitive performance [RR = 1.28 (1.17-1.40); I = 0; p = 0.62]; higher income [RR = 1.63 (1.05-2.56); I = 0; p = 0.52]; being employed [RR = 0.87 (0.83-0.90); I = 0; p = 0.76] and using multiple drugs/inhalers [RR = 0.81 (0.79-0.84); I = 0; p = 0.80]. Overall, the strength of the underlying evidence was only low to moderate.
CONCLUSIONS
Many determinants may be associated to patient's adherence, and personalised interventions should be taken in clinical practice to address it by gaining an understanding of their individual features.

Meta-Analysis Review
Effects of individualized positive end-expiratory pressure combined with recruitment maneuver on intraoperative ventilation during abdominal surgery: a systematic review and network meta-analysis of randomized controlled trials.
Low tidal volume ventilation strategy may lead to atelectasis without proper positive end-expiratory pressure (PEEP) and recruitment maneuver (RM) settings. RM followed by individualized PEEP was a new method to optimize the intraoperative pulmonary function. We conducted a systematic review and network meta-analysis of randomized clinical trials to compare the effects of individualized PEEP + RM on intraoperative pulmonary function and hemodynamic with other PEEP and RM settings. The primary outcomes were intraoperative oxygenation index and dynamic compliance, while the secondary outcomes were intraoperative heart rate and mean arterial pressure. In total, we identified 15 clinical trials containing 36 randomized groups with 3634 participants. Ventilation strategies were divided into eight groups by four PEEP (L: low, M: moderate, H: high, and I: individualized) and two RM (yes or no) settings. The main results showed that IPEEP + RM group was superior to all other groups regarding to both oxygenation index and dynamic compliance. LPEEP group was inferior to LPEEP + RM, MPEEP, MPEEP + RM, and IPEEP + RM in terms of oxygenation index and LPEEP + RM, MPEEP, MPEEP + RM, HPEEP + RM, IPEEP, and IPEEP + RM in terms of dynamic compliance. All comparisons were similar for secondary outcomes. Our analysis suggested that individualized PEEP and RM may be the optimal low tidal volume ventilation strategy at present, while low PEEP without RM is not suggested.

INTRODUCTION
Direct quantification of drug concentrations allows for medication adherence monitoring (MAM) and therapeutic drug monitoring (TDM). Multiple less invasive methods have been developed in recent years: dried blood spots (DBS), saliva, and hair analyses.
AIM
To provide an overview of emerging drug quantification methods for MAM and TDM, focusing on the clinical validation of methods in patients prescribed chronic drug therapies.
METHODS
A scoping review was performed using a systematic search in three electronic databases covering the period 2000-2020. Screening and inclusion were performed by two independent reviewers in Rayyan. Data from the articles were aggregated in a REDCap database. The main outcome was clinical validity of methods based on study sample size, means of cross-validation, and method description. Outcomes were reported by matrix, therapeutic area and application (MAM and/or TDM).
RESULTS
A total of 4590 studies were identified and 175 articles were finally included; 57 on DBS, 66 on saliva and 55 on hair analyses. Most reports were in the fields of neurological diseases (37%), infectious diseases (31%), and transplantation (14%). An overview of clinical validation was generated of all measured drugs. A total of 62 drugs assays were applied for MAM and 131 for TDM.
CONCLUSION
MAM and TDM are increasingly possible without traditional invasive blood sampling: the strengths and limitations of DBS, saliva, and hair differ, but all have potential for valid and more convenient drug monitoring. To strengthen the quality and comparability of future evidence, standardisation of the clinical validation of the methods is recommended.
