Meta-Analysis
BACKGROUND
Riociguat therapy has been recommended for pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH), and it might have therapeutic significance for other types of pulmonary hypertension (PH). Our purpose was to evaluate the specific impact of riociguat on all types of PH.
METHODS
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing the safety and efficacy of riociguat treatment for PH through databases of the Cochrane Library, PubMed, Embase, and Web of Science from inception to the present. Duplicate publications, studies with no full text, incomplete information or inability to extract data, animal experiments and reviews, and systematic reviews were excluded. The software RevMan 5.4 was used for data synthesis.
RESULTS
There were 8 RCTs included in our study, involving 1,606 participants. For PAH and CTEPH patients, riociguat treatment extended 6-minute walk distance (6MWD) by 39.84 meters, decreased mean pulmonary arterial pressure (PAP) by 4.20 mmHg, lowered pulmonary vascular resistance (PVR) by 218.76 dynes/sec/cm-5, cut down right atrial pressure (RAP) by 0.9 mmHg, increased cardiac index (CI) by 0.49 L/min/m2, improved cardiac output (CO) by 0.89 L/min, reduced N-terminal pro-type B natriuretic peptide (NT-proBNP) by 436.21 pg/mL, and decreased adverse events and clinical worsening as compared with placebo. For other types of PH including PH due to left heart disease and PH due to lung disease, riociguat was reported as having improved CI by 0.42 L/min/m2 and CO was increased by 0.92 L/min compared with placebo. Other efficacy outcomes and safety outcomes did not attain statistical difference in other types of PH.
CONCLUSIONS
For PAH and CTEPH, riociguat treatment is safe and effective, but for other types of PH, it can only improve some hemodynamic parameters.

Meta-Analysis Review
INTRODUCTION
The clinical guideline for the management of sepsis, recommends using arterial blood samples for glycaemic control. A multicentre study in 86 Spanish intensive care units (ICU) revealed that 85.4% of ICUs used capillary puncture.
OBJECTIVE
To analyse the reliability of glycaemia by comparing different blood samples (arterial, venous, capillary) and instruments (glucometers, gasometers, central laboratory). Secondarily, to estimate the effect of confounding variables and the performance of measuring instruments as determined by different quality standards.
METHODOLOGY
Systematic review and meta-analysis with search in PubMed, CINAHL and Embase databases in September-2021 and September-2022, with no time or language limits. Grey literature sources: DART-Europe, OpenGrey and Google Scholar. Results summarised by qualitative (description of results, study characteristics) and quantitative (meta-analysis to assess standardised mean difference) synthesis. Methodological quality of articles assessed with Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2).
PROTOCOL
https://osf.io/ DOI 10.17605/OSF.IO/T8KYP.
RESULTS
A total of 32 articles and 5451 patients were included. No discrepancies were obtained between arterial glucometer vs laboratory samples [bias (95%CI): 0.01 (-0.12 to 0.14) mg/dL]. In contrast, arterial samples with a gasometer did significantly overestimate [bias (95%CI): 0.12 (0.01 to 0.24) mg/dL]. The same trend is seen in capillaries with a glucometer, although not significantly [bias (95%CI): 0.07 (--0.02 to 0.15) mg/dL]. There is discrepancy between studies on the effect of haematocrit and acid-base balance. The greatest consensus is on the poor agreement of glucometer with capillary vs laboratory samples in the presence of shock and vasopressor support, renal failure or during vitamin C treatment.
CONCLUSIONS
The evidence to date recommends the use of arterial blood with a blood glucose meter for better reliability of glycaemic analysis and less effect of possible confounding variables, frequently present in the critically ill adult patient.

Review
The aim of this systematic review is to analyze the recent scientific evidence of the clinical effects of altitude on breathing during sleep in healthy persons and sleep disordered patients. A search was carried out in PubMed and Scopus looking for articles published between January 1, 2010 and December 31, 2021, in English and Spanish, with the following search terms: "sleep disorders breathing and altitude". Investigations in adults and carried out at an altitude of 2000 meters above mean sea level (MAMSL) or higher were included. The correlation between altitude, apnea hypopnea index (AHI) and mean SpO2 during sleep was calculated. 18 articles of the 112 identified were included. A good correlation was found between altitude and AHI (Rs = 0.66 P = 0.001), at the expense of an increase in the central apnea index. Altitude is inversely proportional to oxygenation during sleep (Rs = -0.93 P = 0.001), and an increase in the desaturation index was observed (3% and 4%). On the treatment of respiratory disorders of sleeping at altitude, oxygen is better than servoventilation to correct oxygenation during sleep in healthy subjects and acetazolamide controlled respiratory events and oxygenation during sleep in patients with obstructive sleep apnea under treatment with CPAP. Altitude increases AHI and decreases oxygenation during sleep; oxygen and acetazolamide could be an effective treatment for sleep-disordered breathing at altitude above 2000 MAMSL.

Late Cardiological Sequelae and Long-Term Monitoring in Classical Hodgkin Lymphoma and Diffuse Large B-Cell Lymphoma Survivors: A Systematic Review by the Fondazione Italiana Linfomi.
Cardiotoxicity represents the most frequent cause with higher morbidity and mortality among long-term sequelae affecting classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL) patients. The multidisciplinary team of Fondazione Italiana Linfomi (FIL) researchers, with the methodological guide of Istituto di Ricerche Farmacologiche "Mario Negri", conducted a systematic review of the literature (PubMed, EMBASE, Cochrane database) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, in order to analyze the following aspects of cHL and DLBCL survivorship: (i) incidence of cardiovascular disease (CVD); (ii) risk of long-term CVD with the use of less cardiotoxic therapies (reduced-field radiotherapy and liposomal doxorubicin); and (iii) preferable cardiovascular monitoring for left ventricular (LV) dysfunction, coronary heart disease (CHD) and valvular disease (VHD). After the screening of 659 abstracts and related 113 full-text papers, 23 publications were eligible for data extraction and included in the final sample. There was an increased risk for CVD in cHL survivors of 3.6 for myocardial infarction and 4.9 for congestive heart failure (CHF) in comparison to the general population; the risk increased over the years of follow-up. In addition, DLBCL patients presented a 29% increased risk for CHF. New radiotherapy techniques suggested reduced risk of late CVD, but only dosimetric studies were available. The optimal monitoring of LV function by 2D-STE echocardiography should be structured according to individual CV risk, mainly considering as risk factors a cumulative doxorubicine dose >250 mg per square meter (m) and mediastinal radiotherapy >30 Gy, age at treatment <25 years and age at evaluation >60 years, evaluating LV ejection fraction, global longitudinal strain, and global circumferential strain. The evaluation for asymptomatic CHD should be offered starting from the 10th year after mediastinal RT, considering ECG, stress echo, or coronary artery calcium (CAC) score. Given the suggested increased risks of cardiovascular outcomes in lymphoma survivors compared to the general population, tailored screening and prevention programs may be warranted to offset the future burden of disease.

Review
Are assessment measures for components of the International Classification of Functioning, Disability and Health reproducible for use on pre-frail and frail older adults? A systematic review.
OBJECTIVE
To analyze the internal consistency, reliability and measurement error of assessment measures for body structure and function (postural balance, muscle strength, cardiorespiratory function and physical fitness), activity (walking and mobility) and participation (quality of life and social reintegration) outcomes for use on pre-frail and frail older adults.
METHODS
Searches were performed in six databases (Medline, Embase, ScienceDirect, Web of Science, The Cochrane Library and Lilacs) and reproducibility studies were included. Cronbach's alpha and the classification proposed by Terwee et al. (2007) were used for the interpretation of internal consistency. The intraclass correlation coefficient (ICC) and the Munro classification were used for the determination of reliability. The standard error of measurement (SEM), minimal detectable change (MDC) as well as percentages of error (SEM%) and change (MDC%) were calculated. Methodological quality of the studies was appraised using Boxes 4, 6 and 7 of the COSMIN Risk of Bias checklist.
RESULTS
Six studies were included in the present systematic review, with a total of 835 (82.4 years; 582 women and 253 men) pre-frail and frail older adults analyzed. Seven measures were identified for the assessment of body structure and function, activity and participation outcomes (Hierarchical Assessment of Balance and Mobility, Self-Assessment of Physical Fitness, Sarcopenia Quality of Life, Reintegration to Normal Living Index, Two-Minute Walking test, Six-Minute Walking test and Ten-Meter Walking test). The following measurement properties were identified: internal consistency = 0.84 (mean Cronbach's alpha); reliability = 0.87 (mean ICC); SEM range = 0.06 to 10.10; MDC range = 0.13 to 28.10; SEM% range = 5.2 % to 9.5 %; and MDC% range = 10.7 % to 28.5 %.
CONCLUSION
The present systematic review found adequate internal consistency, high reliability and an acceptable measurement error for assessment measures of body structure and function, activity and participation outcomes for use on pre-frail and frail older adults.

Review
A large number of power meters have become commercially available during the last decades to provide power output (PO) measurement. Some of these power meters were evaluated for validity in the literature. This study aimed to perform a review of the available literature on the validity of cycling power meters. PubMed, SPORTDiscus, and Google Scholar have been explored with PRISMA methodology. A total of 74 studies have been extracted for the reviewing process. Validity is a general quality of the measurement determined by the assessment of different metrological properties: Accuracy, sensitivity, repeatability, reproducibility, and robustness. Accuracy was most often studied from the metrological property (74 studies). Reproducibility was the second most studied (40 studies) property. Finally, repeatability, sensitivity, and robustness were considerably less studied with only 7, 5, and 5 studies, respectively. The SRM power meter is the most used as a gold standard in the studies. Moreover, the number of participants was very different among them, from 0 (when using a calibration rig) to 56 participants. The PO tested was up to 1700 W, whereas the pedalling cadence ranged between 40 and 180 rpm, including submaximal and maximal exercises. Other exercise conditions were tested, such as torque, position, temperature, and vibrations. This review provides some caveats and recommendations when testing the validity of a cycling power meter, including all of the metrological properties (accuracy, sensitivity, repeatability, reproducibility, and robustness) and some exercise conditions (PO range, sprint, pedalling cadence, torque, position, participant, temperature, vibration, and field test).

Review
BACKGROUND
About half of survivors with stroke experience severe and significant long-term disability. The purpose of this article is to review the state of the science and to make recommendations for measuring patient-centric outcomes in interventions for motor improvement in the chronic stroke phase.
METHODS AND RESULTS
A 9-member expert panel reviewed evidence to identify measures of upper and lower extremity function used to date as outcomes in trials with patients who experienced a stroke ≥6 months before assessment. Outcome measures were screened using StrokEDGE consensus panel recommendations, and evaluated for availability of a published minimal clinically important difference. Measures meeting these criteria were further evaluated with regard to their level of measurement, psychometric properties, and ability of minimal clinically important difference to capture gains associated with improved function and clinical relevance to patients, to arrive at recommendations. A systematic literature review yielded 115 clinical trials of upper and lower extremity function in chronic stroke that used a total of 34 outcome measures. Seven of these had published minimal clinically important differences and were recommended or highly recommended by StrokEDGE. Those are the Fugl-Meyer Upper Extremity and Lower Extremity scales, Wolf Motor Function Test, Action Research Arm Test, Ten-Meter and Six-Minute Walk Tests, and the Stroke Impact Scale. All had evidence for their psychometric performance, although the strength of evidence for validity varied, especially in populations with chronic stroke Fugl-Meyer Upper and Lower Extremity scales showing the strongest evidence for validity.
CONCLUSIONS
The panel recommends that the Fugl-Meyer Upper and Lower Extremity scales be used as primary outcomes in intervention trials targeting motor function in populations with chronic stroke. The other 6 measures are recommended as secondary outcomes.

Review
An understanding of physical demands during official competitions is essential to achieving the highest performance in handball. The aim of this systematic review was to summarise the available scientific evidence associated with physical demands during official competitions in elite handball according to playing positions, competition level and gender. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 17 studies were selected after a systematic search and selection process of three digital databases: PubMed, Web of Science and Sport Discus. The quality of the selected studies was evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology checklist; the average score was 18.47 points. The sample consisted of 1175 handball players, of whom 1042 were men (88.68%) and 133 were women (11.32%). The results show that an elite handball player covered on average 3664.4 ± 1121.6 m during a match. The average running pace was 84.8 ± 17.2 m∙min. The total distance covered was largely greater in national competitions (4506.7 ± 647.9 m) compared with international competitions (2190.3 ± 1950.5 m) (effect size (ES) = 1.2); however, the running pace did not present any significant difference between the international or national level (ES = 0.06). In regard to gender, the total distance covered was moderately greater in female competitions (4549.1 ± 758.6 m) compared with male competitions (3332.6 ± 1257.7 m) (ES = 0.9), and the running pace was largely greater in female competitions (110.5 ± 7.2 m∙min) compared with male competitions (78.4 ± 19.7 m∙min) (ES = 1.6). In relation to playing position, backs and wings covered a moderately greater total distance (ES = 0.7 and 0.6) and slightly more meters per minute (ES = 0.4 and 0.2) than pivots. Moreover, the technical activity profile differed between playing positions. Backs performed moderately more throws than pivots and wings (ES = 1.2 and 0.9), pivots exhibited largely more body contact than backs and wings, and wings performed moderately more fast breaks (6.7 ± 3.0) than backs (2.2 ± 2.3) (ES = 1.8). Therefore, this research study provides practical applications for handball coaches and strength and conditioning professionals with respect to designing and implementing more individualised training programmes to maximise performance and reduce injury risk.

Review
Integrated sensor-augmented pump therapy systems [the MiniMed® Paradigm™ Veo system and the Vibe™ and G4® PLATINUM CGM (continuous glucose monitoring) system] for managing blood glucose levels in type 1 diabetes: a systematic review and economic evaluation.
BACKGROUND
In recent years, meters for continuous monitoring of interstitial fluid glucose have been introduced to help people with type 1 diabetes mellitus (T1DM) to achieve better control of their disease.
OBJECTIVE
The objective of this project was to summarise the evidence on the clinical effectiveness and cost-effectiveness of the MiniMed(®) Paradigm™ Veo system (Medtronic Inc., Northridge, CA, USA) and the Vibe™ (Animas(®) Corporation, West Chester, PA, USA) and G4(®) PLATINUM CGM (continuous glucose monitoring) system (Dexcom Inc., San Diego, CA, USA) in comparison with multiple daily insulin injections (MDIs) or continuous subcutaneous insulin infusion (CSII), both with either self-monitoring of blood glucose (SMBG) or CGM, for the management of T1DM in adults and children.
DATA SOURCES
A systematic review was conducted in accordance with the principles of the Centre for Reviews and Dissemination guidance and the National Institute for Health and Care Excellence Diagnostic Assessment Programme manual. We searched 14 databases, three trial registries and two conference proceedings from study inception up to September 2014. In addition, reference lists of relevant systematic reviews were checked. In the absence of randomised controlled trials directly comparing Veo or an integrated CSII + CGM system, such as Vibe, with comparator interventions, indirect treatment comparisons were performed if possible.
METHODS
A commercially available cost-effectiveness model, the IMS Centre for Outcomes Research and Effectiveness diabetes model version 8.5 (IMS Health, Danbury, CT, USA), was used for this assessment. This model is an internet-based, interactive simulation model that predicts the long-term health outcomes and costs associated with the management of T1DM and type 2 diabetes. The model consists of 15 submodels designed to simulate diabetes-related complications, non-specific mortality and costs over time. As the model simulates individual patients over time, it updates risk factors and complications to account for disease progression.
RESULTS
Fifty-four publications resulting from 19 studies were included in the review. Overall, the evidence suggests that the Veo system reduces hypoglycaemic events more than other treatments, without any differences in other outcomes, including glycated haemoglobin (HbA1c) levels. We also found significant results in favour of the integrated CSII + CGM system over MDIs with SMBG with regard to HbA1c levels and quality of life. However, the evidence base was poor. The quality of the included studies was generally low, often with only one study comparing treatments in a specific population at a specific follow-up time. In particular, there was only one study comparing Veo with an integrated CSII + CGM system and only one study comparing Veo with a CSII + SMBG system in a mixed population. Cost-effectiveness analyses indicated that MDI + SMBG is the option most likely to be cost-effective, given the current threshold of £30,000 per quality-adjusted life-year gained, whereas integrated CSII + CGM systems and Veo are dominated and extendedly dominated, respectively, by stand-alone, non-integrated CSII with CGM. Scenario analyses did not alter these conclusions. No cost-effectiveness modelling was conducted for children or pregnant women.
CONCLUSIONS
The Veo system does appear to be better than the other systems considered at reducing hypoglycaemic events. However, in adults, it is unlikely to be cost-effective. Integrated systems are also generally unlikely to be cost-effective given that stand-alone systems are cheaper and, possibly, no less effective. However, evidence in this regard is generally lacking, in particular for children. Future trials in specific child, adolescent and adult populations should include longer term follow-up and ratings on the European Quality of Life-5 Dimensions scale at various time points with a view to informing improved cost-effectiveness modelling.

Review
OBJECTIVE
Soccer match-play is typically contested over 90 min; however, in some cup and tournament scenarios, when matches are tied, they proceed to an additional 30 min, which is termed "extra-time" (ET). This systematic review sought to appraise the literature available on 120-min of soccer-specific exercise, with a view to identifying practical recommendations and future research opportunities.
METHODS
The review was conducted according to the PRISMA guidelines. Independent researchers performed a systematic search of PubMed, CINAHL, and PsycINFO in May 2019, with the following keywords entered in various combinations: "soccer", "football", "extra-time", "extra time", "extratime", "120 minutes", "120 min", "additional 30 minutes", and "additional 30 min".
RESULTS
The search yielded an initial 73 articles. Following the screening process, 11 articles were accepted for analyses. Articles were subsequently organized into the following 5 categories: movement demands of ET, performance responses to ET, physiological and neuromuscular response during ET, nutritional interventions, and recovery and ET. The results highlighted that during competitive match-play, players cover 5%-12% less distance relative to match duration (i.e., meters per minute) during ET compared to the preceding 90 min. Reductions in technical performance (i.e., shot speed, number of passes and dribbles) were also observed during ET. Additionally, carbohydrate provision may attenuate and improve dribbling performance during ET. Moreover, objective and subjective measures of recovery may be further compromised following ET when compared to 90 min.
CONCLUSION
Additional investigations are warranted to further substantiate these findings and identify interventions to improve performance during ET.
