Meta-Analysis Review
BACKGROUND
Lung disease in preterm infants is often complicated with lung edema.
OBJECTIVES
To assess the risks and benefits of administration of a diuretic acting on the loop of Henle (loop diuretic) in preterm infants with or developing chronic lung disease (CLD).
SEARCH STRATEGY
Standard search method of the Cochrane Neonatal Review Group was used. Initial search included the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2003), MEDLINE (1966 to April 2003), EMBASE (1974 to 1998). In addition, several abstract books of national and international American and European Societies were hand searched. The MEDLINE and the Cochrane Central searches were updated in March 2007 and December 2010. The EMBASE search was completed in April 2007 and December 2010. Additional searches in CINAHL, clinicaltrials.gov and controlled-trials.com was completed in December 2010.
SELECTION CRITERIA
Trials in which preterm infants with or developing chronic lung disease and at least five days of age were all randomly allocated to receive a loop diuretic either enterally or intravenously were included in this analysis.
DATA COLLECTION AND ANALYSIS
The standard method for the Cochrane Collaboration described in the Cochrane Collaboration Handbook were used. Two investigators extracted, assessed and coded separately all data for each study. Parallel and cross-over trials were combined and, whenever possible, transformed baseline and final outcome data measured on a continuous scale into change scores using Follmann's formula.
MAIN RESULTS
The only loop diuretic used in the six studies that met the selection criteria was furosemide. Most studies focused on pathophysiological parameters and did not assess effects on important clinical outcomes defined in this review, or the potential complications of diuretic therapy. In preterm infants < 3 weeks of age developing CLD, furosemide administration has either inconsistent effects or no detectable effect. In infants > 3 weeks of age with CLD, a single intravenous dose of 1 mg/kg of furosemide improves lung compliance and airway resistance for one hour. Chronic administration of furosemide improves both oxygenation and lung compliance.
AUTHORS' CONCLUSIONS
In view of the lack of data from randomized trials concerning effects on important clinical outcomes, routine or sustained use of systemic loop diuretics in infants with (or developing) CLD cannot be recommended based on current evidence. Randomized trials are needed to assess the effects of furosemide administration on survival, duration of ventilatory support and oxygen administration, length of hospital stay, potential complications and long-term outcome.

The Cochrane Database of Systematic... 2000Hip fracture patients have a high risk of thromboembolic complications following surgical management. (Review)
Review
BACKGROUND
Hip fracture patients have a high risk of thromboembolic complications following surgical management.
OBJECTIVES
To examine the effects of heparin (unfractionated (U), and low molecular weight (LMW) heparins), and physical methods (compression stockings, calf or foot pumps) for prevention of deep venous thrombosis (DVT) and pulmonary embolism after surgery for hip fracture in the elderly.
SEARCH STRATEGY
We searched the Cochrane Musculoskeletal Injuries Group trials register, Medline, Embase, and reference lists of published papers and books. We contacted trialists and other workers in the field. Date of most recent search: September 1996.
SELECTION CRITERIA
Randomised and quasi-randomised trials evaluating the use of heparins and physical agents for prevention of DVT and pulmonary embolism in patients undergoing surgery for hip fracture.
DATA COLLECTION AND ANALYSIS
Two reviewers independently assessed methodological quality and extracted data. Trials were grouped into four categories (heparin versus control, mechanical versus control, LMW heparin versus U heparin, and miscellaneous) and results pooled where possible.
MAIN RESULTS
The 26 included trials involved 2600 predominantly female and elderly patients. Overall, trial quality was disappointing. Ten trials involving 826 patients which compared U heparin with control, and four trials of 471 patients which compared LMW heparin with control, showed a reduction in the incidence of lower limb DVT (121/511 (24%) versus 203/519 (39%); Peto odds ratio 0.41; 95% confidence interval 0.31 to 0.55). There were insufficient data to confirm the efficacy of either agent in the prevention of pulmonary embolism. There was a non significant increase in overall mortality in the heparin group (46/420 (11%) versus 35/423 (8%); Peto odds ratio 1.39; 95% confidence interval 0. 86 to 2.23). Data were inadequate for all other outcomes including wound complications. There is insufficient evidence from five trials, involving 644 patients, to establish if LMW heparin was superior to U heparin. Most trials evaluating heparins had methodological defects. Four trials, involving 442 patients, testing mechanical pumping devices were also methodologically flawed, and so pooled results need to be viewed cautiously. Mechanical pumping devices may protect against DVT (12/202 (6%) versus 42/212 (19%); Peto odds ratio 0.24; 95% confidence interval 0.13 to 0.44). Although the limited data indicated a potential benefit, they were inadequate to establish any effect on the incidence of pulmonary embolism and overall mortality. Problems with skin abrasion and compliance were reported.
REVIEWER'S CONCLUSIONS
U and LMW heparins protect against lower limb DVT. There is insufficient evidence to confirm either protection against pulmonary embolism or overall benefit, or to distinguish between various applications of heparin. Foot and calf pumping devices appear to prevent DVT, may protect against pulmonary embolism, and reduce mortality, but compliance remains a problem. Good quality trials of mechanical methods as well as direct comparisons with heparin should be considered.

Review
INTRODUCTION
Understanding the breadth of patients' support needs is important for the delivery of person-centered care, particularly in progressive long-term conditions such as chronic obstructive pulmonary disease (COPD). Existing reviews identify important aspects of managing life with COPD with which patients may need support (support needs); however, none of these comprehensively outlines the full range of support needs that patients can experience. We therefore sought to systematically determine the full range of support needs for patients with COPD to inform development of an evidence-based tool to enable person-centered care.
METHODS
We conducted a systematic search and narrative review of the literature. Medline (Ovid), EMBASE, PsycINFO, Cochrane Library, and CINAHL were systematically searched for papers which included data addressing key aspects of support need, as identified by patients with COPD. Relevant data were extracted, and a narrative analysis was conducted.
RESULTS
Thirty-one papers were included in the review, and the following 13 domains (broad areas) of support need were identified: 1) understanding COPD, 2) managing symptoms and medication, 3) healthy lifestyle, 4) managing feelings and worries, 5) living positively with COPD, 6) thinking about the future, 7) anxiety and depression, 8) practical support, 9) finance work and housing, 10) families and close relationships, 11) social and recreational life, 12) independence, and 13) navigating services. These 13 domains of support need were mapped to three of the four overarching categories of need commonly used in relevant national strategy documents (ie, physical, psychological, and social); however, support needs related to the fourth category (spiritual) were notably absent.
CONCLUSION
This review systematically identifies the comprehensive set of domains of support need for patients with COPD. The findings provide the evidence base for a tool to help patients identify and express their support needs, which underpins a proposed intervention to enable the delivery of person-centered care: the Support Needs Approach for Patients (SNAP).

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
Preterm birth causes constant challenges, with bronchopulmonary dysplasia (BPD) being a major concern. Immediately after birth, it takes time to establish feeding between the mother and the premature baby. During this time, the telological shifting of fluid from extracellular space to intracellular space will help the baby; this transition should be smooth. Both normal physiologic changes and pathophysiologic events are capable of disrupting this delicate fluid shifting that occurs in very low-birth-weight infants during the first week of life. The immaturity of the renal system and evaporative losses complicate this process. This lack of fluid displacement can be associated with an increased amount of water in the lungs and reduced lung compliance. This can lead to the need for more ventilatory support and a higher oxygen requirement, which, in turn, leads to lung damage. The fluid restriction is also associated with complications such as severe dehydration, intracranial hemorrhage, and bilirubin toxicity. However, the administration of large amounts of fluid and salt is associated with an increased incidence of patent ductus arteriosus, BPD, necrotizing enterocolitis, and intraventricular hemorrhage. There were studies conducted in both the pre-surfactant and surfactant eras that were inconclusive regarding fluid restriction in BPD. We only included very recent studies. This systematic review attempts to summarize the current evidence, focusing on the efficacy and safety of early fluid management in preterm infants. This reduces the risk of BPD and improves outcomes for premature infants. As we know, intact survival is very important. Our review supported the early fluid restriction.

PURPOSE
An ever-growing number of predictive models used to inform clinical decision making have included quantitative, computer-extracted imaging biomarkers, or "radiomic features." Broadly generalizable validity of radiomics-assisted models may be impeded by concerns about reproducibility. We offer a qualitative synthesis of 41 studies that specifically investigated the repeatability and reproducibility of radiomic features, derived from a systematic review of published peer-reviewed literature.
METHODS AND MATERIALS
The PubMed electronic database was searched using combinations of the broad Haynes and Ingui filters along with a set of text words specific to cancer, radiomics (including texture analyses), reproducibility, and repeatability. This review has been reported in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. From each full-text article, information was extracted regarding cancer type, class of radiomic feature examined, reporting quality of key processing steps, and statistical metric used to segregate stable features.
RESULTS
Among 624 unique records, 41 full-text articles were subjected to review. The studies primarily addressed non-small cell lung cancer and oropharyngeal cancer. Only 7 studies addressed in detail every methodologic aspect related to image acquisition, preprocessing, and feature extraction. The repeatability and reproducibility of radiomic features are sensitive at various degrees to processing details such as image acquisition settings, image reconstruction algorithm, digital image preprocessing, and software used to extract radiomic features. First-order features were overall more reproducible than shape metrics and textural features. Entropy was consistently reported as one of the most stable first-order features. There was no emergent consensus regarding either shape metrics or textural features; however, coarseness and contrast appeared among the least reproducible.
CONCLUSIONS
Investigations of feature repeatability and reproducibility are currently limited to a small number of cancer types. Reporting quality could be improved regarding details of feature extraction software, digital image manipulation (preprocessing), and the cutoff value used to distinguish stable features.

Review
A systematic review was conducted in compliance with PRISMA statement standards to identify all studies reporting outcomes of laparoscopic resection of benign or malignant lesions located in caudate lobe of liver. Pooled outcome data were calculated using random-effects models. A total of 196 patients from 12 studies were included. Mean operative time, volume of intraoperative blood loss, and length of hospital stay were 225 minutes (95% confidence interval [CI], 181-269 minutes), 134 mL (95% CI, 85-184 mL), and 7 days (95% CI, 5-9 days), respectively. The pooled risk of need for intraoperative transfusion was 2% (95% CI, 0%-5%). It was 3% (95% CI, 1%-6%) for conversion to open surgery, 6% (95% CI, 0%-19%) for need for intra-abdominal drain, 1% (95% CI, 0%-3%) for postoperative mortality, 2% (95% CI, 0%-4%) for biliary leakage, 2% (95% CI, 0%-4%) for intra-abdominal abscess, 1% (95% CI, 0%-4%) for biliary stenosis, 1% (95% CI, 0%-3%) for postoperative bleeding, 1% (95% CI, 0%-4%) for pancreatic fistula, 2% (95% CI, 1%-5%) for pulmonary complications, 1% (95% CI, 0%-4%) for paralytic ileus, and 1% (95% CI, 0%-4%) for need for reoperation. Although the available evidence is limited, the findings of the current study might be utilized for hypothesis synthesis in future studies. They can be used to inform surgeons and patients about estimated risks of perioperative complications until a higher level of evidence is available.

BACKGROUND
Although pulmonary rehabilitation (PR) is considered a key component in managing chronic obstructive pulmonary disease (COPD) patients, uptake remains suboptimal. This systematic review aimed to determine the effectiveness of home-based PR (HBPR) programs for COPD patients.
METHODS
A systematic review of scholarly literature published within the last 10 years from the conception of this project was conducted using internationally recognized guidelines. Search strategies were applied to electronic databases and clinical trial registries through March 2020 and updated in November 2021 to identify studies comparing HBPR with 'usual care' or outpatient pulmonary rehabilitation (OPR). To critically appraise randomized studies, the Cochrane Collaboration risk of bias tool (ROB) was used. The quality of non-randomized studies was evaluated using the ACROBAT-NRSI tool. The quality of evidence relating to key outcomes was assessed using Grading of Recommendations, Assessment, Development and Evaluations (GRADE) on health-related quality of life (HRQoL), exacerbation frequencies, COPD-related hospital admissions, and program adherence. Three independent reviewers assessed methodologic quality and reviewed the studies.
RESULTS
Twelve randomized controlled trials (RCTs) and 2 comparative observational studies were included. While considerable evidence relating to the effectiveness of HBPR programs for COPD patients exist, overall quality is low. There were no differences between HBPR and OPR in terms of safety, HRQoL, functional exercise capacity and health care resource utilization. Compared to usual care, functional exercise capacity seemed to significantly improve after HBPR. While patient compliance with HBPR is good, two factors appeared to increase the 'risk' of non-compliance: expectations of patients to 1) complete daily diaries/activity logs and 2) engage in solely unsupervised exercise sessions.
CONCLUSION
The overall quality for most outcomes was low to very low; however, HBPR seems to offer comparable short-term benefits to OPR.

Meta-Analysis Review
OBJECTIVES
We aimed to investigate published data on treatment outcomes of multidrug-resistant (MDR)/rifampicin-resistant tuberculosis (TB) in Central and West Africa because these, to the best of our knowledge, are sparsely available.
METHODS
Systematic review and meta-analysis.
RESULTS
A total of 14 studies were included, representing 4268 individuals in 14 of the 26 countries. Using a random-effects model meta-analysis, we observed a pooled success rate of 80.8% (95% confidence interval [CI] 56.0-93.3) for the Central African subgroup and 69.2% (95% CI 56.3-79.7) for the West African subgroup (P = 0.0522). The overall treatment success for all studies was 74.6% (95% CI 65.0-82.2). We found high heterogeneity among included studies (I = 96.1%). The estimated proportion of successfully treated individuals with MDR/rifampicin-resistant TB was considerably higher than the global estimate provided by the World Health Organization (59%), reaching the 2015 World Health Organization target of at least 75% treatment success for MDR-TB.
CONCLUSION
The use of shorter treatment regimens and the standardized treatment conditions, including directly observed therapy in these studies, could have contributed to a high treatment success. Yet, the available literature was not fully representative of the regions, possibly highlighting the sparse resources in many of these countries. The review was registered at PROSPERO (https://www.crd.york.ac.uk/prospero/) (CRD42022353163).

Meta-Analysis
Does health coaching improve health-related quality of life and reduce hospital admissions in people with chronic obstructive pulmonary disease? A systematic review and meta-analysis.
PURPOSE
To systematically review the evidence for health coaching as an intervention to improve health-related quality of life (HRQoL) and reduce hospital admissions in people with chronic obstructive pulmonary disease (COPD).
METHODS
We systematically searched MEDLINE, EMBASE, PsycINFO, and CINAHL from database inception to August 2018 to identify all randomized controlled trials (RCTs) of health coaching for people with COPD. Eligible health coaching interventions had to include three components: goal setting, motivational interviewing, and COPD-related health education. Data were extracted on study characteristics and the effects of the intervention on HRQoL, hospital admissions, physical activity, self-care behaviour, and mood. Study quality was appraised by two authors using the Cochrane tool for assessing the risk of bias in RCTs. Effect sizes (standardized mean differences [SMD] or odds ratios [OR]) with 95% confidence intervals (CIs) were calculated and pooled using random effects meta-analyses.
RESULTS
Of 1578 articles, 10 RCTs were included. Meta-analysis showed that health coaching has a significant positive effect on HRQoL (SMD = -0.69, 95% CI: -1.28, -0.09, p = .02, from k = 4) and leads to a significant reduction in COPD-related hospital admissions (OR = 0.46, 95% CI: 0.31, 0.69, p = .0001, from k = 5), but not in all-cause hospital admissions (OR = 0.70, 95% CI: 0.41-1.12, p = .20, from k = 3). Three of four studies reported significant improvements to self-care behaviours such as medication adherence and exercise compliance.
CONCLUSIONS
This is the first systematic review to show that health coaching may be a candidate intervention to improve HRQoL and reduce costly hospital admissions in people with COPD. Statement of contribution What is already known on this subject? COPD is a leading cause of death worldwide and considerably reduces HRQoL. In turn, HRQoL is associated with a range of adverse health outcomes in COPD. Health coaching is a self-management intervention for people with long-term conditions such as COPD. Studies have examined whether health coaching improves HRQOL and other health outcomes in people with COPD, but no systematic review has been conducted. What does this study add? The first systematic review and meta-analysis of RCTs of health coaching for people with COPD. Health coaching may be a candidate intervention for improving HRQoL and reducing COPD-related hospital admissions in people with COPD. The need to establish the most effective health coaching components, delivery modality, and economic impact.
