Study design:A prospective cohort study.Objectives:To evaluate whether patients with cervical spinal cord injury (CSCI) are able to learn the technique of glossopharyngeal pistoning (breathing) for lung insufflation (GI) and if learned, to evaluate the effects of GI on pulmonary function and chest expansion after 8 weeks.Setting:Karolinska University Hospital, Stockholm, Sweden.Methods:Twenty-five patients with CSCI (21 men, four women) with a mean age of 46 years (21–70), from the Stockholm area, were used in this study. The participants performed 10 cycles of GI four times a week, for 8 weeks. Pulmonary function tests made before and after the GI training included vital capacity (VC), expiratory reserve volume (ERV), functional residual capacity (FRC; measured with nitrogen washout), residual volume (RV) and total lung capacity (TLC). Chest expansion was measured before and after training.Results:Five of the twenty-five participants had difficulty in performing GI and were excluded in further analysis. Performing a GI maneuvre increased participants' VC on average by 0.88±0.5 l. After 8 weeks of training, the participants had significantly increased their VC 0.23 l, (P<0.001), ERV 0.16 l, (P<0.01), FRC 0.86 l, (P<0.001), RV 0.70 l, (P<0.001) and TLC 0.93 l, (P<0.001). Chest expansion increased at the level of the xiphoid process by 1.2 cm (P<0.001) and at the level of the fourth costae by 0.7 cm (P<0.001).Conclusions:After using GI for a period of 8 weeks, the participants with CSCI who could perform GI were able to improve pulmonary function and chest expansion.Spinal Cord (2009) 47, 418–422; doi:10.1038/sc.2008.138; published online 11 November 2008 [ABSTRACT FROM AUTHOR]

Background: Physical activity is thought to be a key component in reducing postoperative complications following major abdominal surgery. The available literature on exercise interventions following radical cystectomy in patients with bladder cancer is scarce but suggests that physical activity and exercise might improve physical function and health-related quality of life, thus calling for further investigation. The CanMoRe-trial is a single-blinded randomised controlled trial (Clinicals Trials NCT03998579 25/06/2019), aimed at evaluating the impact of an exercise intervention in primary care following robot-assisted radical cystectomy. This study seeks to explore patients' experiences of the exercise intervention in the CanMoRe-trial to gain a better understanding of facilitating aspects and potential barriers., Methods: A qualitative study was conducted involving 20 patients from the intervention group of the CanMoRe-trial who were interviewed individually between October 2020 and March 2023 using a semi-structured interview guide. The interviews were recorded and transcribed verbatim and reflexive thematic analysis was used to analyse the data., Results: Four main themes were identified: Having to adapt to new circumstances, describing the challenges regarding physical activity patients face after discharge. Optimising conditions for rehabilitation, describing how practical conditions affect patients' ability to exercise. Motivated to get back to normal, describing patients´ desire to get back to normal life and factors influencing motivation. Importance of a supportive environment, describing the impact of social support, support from physiotherapists, and how the environment where exercise takes place impacts patients' ability to exercise., Conclusion: This study found that patients participating in the CanMoRe-trial are positive towards physical exercise in PC following radical RARC. They are motivated to get back to normal life but face major challenges when arriving home following surgery, which affect their ability to perform physical activity and engage in exercise. Conditions need to be optimised to support patients' ability to engage in exercise by providing an accessible PC location to perform exercise in. A supportive environment is also needed, including guidance from healthcare professionals regarding which type of exercise, intensity and amount of exercise that should be performed, enabling patients gradually to develop self-efficacy regarding exercise and focusing on goals related to patients' normal lives before surgery., (© 2024.

Postural orthostatic tachycardia syndrome (POTS) occurs in approximately 30% of people with highly symptomatic post-COVID-19 condition (PCC). It involves several symptoms that limit physical and psychological functions and cause reduced quality of life. Evidence for different treatments of POTS and PCC is limited, and this study aimed to evaluate the feasibility of individually tailored physical exercise. The secondary aim of the study was to evaluate the preliminary effectiveness of this intervention. Twenty-six participants (81% female, median age 41 years) were enrolled and performed individually tailored endurance and strength training, with progression, for twelve weeks. During the intervention period, the participants had weekly support from a physiotherapist. Feasibility was evaluated with good compliance, with 76% adherence to exercise prescription and 96% completing the study protocol. The treatment was safe, and the evaluation methods (questionnaires, physical assessments, and accelerometer monitoring) were judged to be feasible. After the intervention, improvements in symptom burden as well as in psychological and physical functions were observed. In conclusion, future randomized controlled trials can be performed with only minor adjustments and could include questionnaires, physical assessment and accelerometer monitoring, which were demonstrated as feasible by this study., (© 2024.

Introduction: After radical cystectomy physical activity is important to reduce risk of complications, but patients with urinary bladder cancer have difficulties in achieving general recommendations on physical activity and exercise. The aim of this randomised controlled trial was therefore to evaluate the effects of a physical exercise programme in primary care, following discharge from hospital after robot-assisted radical cystectomy for urinary bladder cancer., Materials and Methods: Patients with urinary bladder cancer scheduled for robot-assisted radical cystectomy at Karolinska University Hospital, Sweden between September 2019 and October 2022 were invited to join the study. At discharge, they were randomised to intervention or active control group. The intervention group was planned to start exercise with physiotherapist in primary care during the third week; the programme included aerobic and strengthening exercises, twice a week for 12 weeks, and daily walks. The control group received unsupervised home-based exercise with daily walks and a sit-to-stand exercise. Assessments were conducted before surgery, at discharge and after four months regarding the primary outcome physical function (Six-minute walk test), and secondary outcomes physical activity, pain, health-related quality of life, fatigue, and psychological wellbeing., Results: Ninety patients were included, mean (sd) age 71.5 (8.5) years. An intention-to-treat analysis showed no intervention effect on the primary outcome physical function, or on pain or psychological wellbeing, but effect on physical activity with a difference from discharge to four months with a median (IQR) of 4790 (3000) and 2670 (4340) daily steps in the intervention and control group, respectively (p = 0.046), and for fatigue, and health-related quality of life, in favour of the intervention group., Conclusion: Both the intervention and control groups improved physical function, but the patients who exercised in primary care experienced additional positive effects on physical activity, fatigue, and health-related quality of life. Hence, exercise in primary care after discharge from hospital could be a promising method after radical cystectomy for urinary bladder cancer., Trial Registration: The study was registered in Clinical Trials with registration number NCT03998579, 20,190,607., (© 2024.

Background: Cardiac surgery is associated with a period of postoperative bed rest. Although early mobilization is a vital component of postoperative care, for preventing complications and enhancing physical recovery, there is limited data on routine practices and optimal strategies for early mobilization after cardiac surgery. The aim of the study was to define the timing for the first initiation of out of bed mobilization after cardiac surgery and to describe the type of mobilization performed., Methods: In this observational study, the first mobilization out of bed was studied in a subset of adult cardiac surgery patients (n = 290) from five of the eight university hospitals performing cardiothoracic surgery in Sweden. Over a five-week period, patients were evaluated for mobilization routines within the initial 24 h after cardiac surgery. Data on the timing of the first mobilization after the end of surgery, as well as the duration and type of mobilization, were documented. Additionally, information on patient characteristics, anesthesia, and surgery was collected., Results: A total of 277 patients (96%) were mobilized out of bed within the first 24 h, and 39% of these patients were mobilized within 6 h after surgery. The time to first mobilization after the end of surgery was 8.7 ± 5.5 h; median of 7.1 [4.5-13.1] hours, with no significant differences between coronary artery bypass grafting, valve surgery, aortic surgery or other procedures (p = 0.156). First mobilization session lasted 20 ± 41 min with median of 10 [1-11]. Various kinds of first-time mobilization, including sitting on the edge of the bed, standing, and sitting in a chair, were revealed. A moderate association was found between longer intubation time and later first mobilization (ρ = 0.487, p < 0.001). Additionally, there was a moderate correlation between the first timing of mobilization duration of the first mobilization session (ρ = 0.315, p < 0.001)., Conclusions: This study demonstrates a median time to first mobilization out of bed of 7 h after cardiac surgery. A moderate correlation was observed between earlier timing of mobilization and shorter duration of the mobilization session. Future research should explore reasons for delayed mobilization and investigate whether earlier mobilization correlates with clinical benefits., Trial Registration: FoU in VGR (Id 275,357) and Clinical Trials (NCT04729634)., (© 2024.

Background: Few studies consider both radiological and functional outcomes in COVID-19 survivors treated in the intensive care unit (ICU). We investigated clinical findings and pulmonary abnormalities on chest computed tomography (CT) and compared outcomes of severe versus mild-moderate acute respiratory distress syndrome (ARDS) on long-term follow-up., Methods: This longitudinal cohort study included 118 COVID-19 patients (median age, 58 years; 79% men). Thoracic CT scans were performed 4, 10, and 22 months after hospital discharge. Two independent blinded radiologists analyzed the 10 months scans and scored the radiology findings semi-quantitatively, as no/minor versus widespread opacities [low-radiology opacity grade (ROG) versus high-ROG]. ARDS severity was based on the PaO2/FiO2 ratio. The 6 min walk test (6MWT) was performed after 3 and 9 months, and lung diffusion capacity for carbon monoxide (DLCO) and lung volume measurement after 9 and 15 months. Dynamic spirometry was done at all time points. Residual symptoms and health-related quality-of-life (HRQL) were evaluated using validated questionnaires., Results: At 10 months, most patients (81/118; 69%) were classified as high-ROG, of which 70% had severe ARDS during hospitalisation; 69% of those with mild-moderate ARDS also had high-ROG. Patients with high-ROG had longer ICU stay and lower PaO2/FiO2 during hospitalisation ( p  < 0.01). At 9 months follow-up, patients with high-ROG had smaller lung volumes as % of predicted values [mean (±CI): 80 (77-84) vs. 93 (88-98) ( p  < 0.001)], lower DLCO as % of predicted values [74 (70-78) vs. 87 (82-92) ( p  < 0.001)], lower oxygen saturation during 6MWT ( p  = 0.02), and a tendency to more severe dyspnoea ( p  = 0.07), but no difference was found in HRQL compared with no/minor ROG ( p  = 0.92). A higher opacity score was related to lower DLCO at follow-up ( r  = -0.48, p  < 0.001, Spearman rank test). Severe ARDS patients had slightly more severe fatigue at 9 months compared to mild-moderate, but no differences in dyspnoea or lung function at follow-up. Fibrotic-like changes were found in 93% of patients examined with CT scans at 2 years (55/118; 47%). Severe ARDS could predict widespread opacities (ROG > 25%) in most patients at follow-up at 10 months (AUC 0.74)., Conclusion: Residual radiological abnormalities in ICU-treated COVID-19 patients, evaluated for up to 2 years, relate to persisting symptoms and impaired lung function, demanding careful follow-up regardless of ARDS severity at hospitalisation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Objectives: Knowledge of clinical practice regarding mobilisation after surgery is lacking. This study therefore aimed to reveal current mobilisation routines after abdominal and cardiothoracic surgery and to identify factors associated with mobilisation within 6 hours postoperatively., Design: A prospective observational national multicentre study., Setting: 18 different hospitals in Sweden., Participants: 1492 adult patients undergoing abdominal and cardiothoracic surgery with duration of anaesthesia>2 hours., Primary and Secondary Outcomes: Primary outcome was time to first postoperative mobilisation. Secondary outcomes were the type and duration of the first mobilisation. Data were analysed using multivariate logistic regression and general structural equation modelling, and data are presented as ORs with 95% CIs., Results: Among the included patients, 52% were mobilised to at least sitting on the edge of the bed within 6 hours, 70% within 12 hours and 96% within 24 hours. Besides sitting on the edge of the bed, 76% stood up by the bed and 22% were walking away from the bedside the first time they were mobilised. Patients undergoing major upper abdominal surgery required the longest time before mobilisation with an average time of 11 hours post surgery. Factors associated with increased likelihood of mobilisation within 6 hours of surgery were daytime arrival at the postoperative recovery unit (OR: 5.13, 95% CI: 2.16 to 12.18), anaesthesia <4 hours (OR: 1.68, 95% CI: 1.17 to 2.40) and American Society of Anaesthesiologists (ASA) classification 1-2, (OR: 1.63, 95% CI: 1.13 to 2.36)., Conclusions: In total, 96% if the patients were mobilised within 24 hours after surgery and 52% within 6 hours. Daytime arrival at the postoperative recovery unit, low ASA classification and shorter duration of anaesthesia were associated with a shorter time to mobilisation., Trial Registration Number: FoU, Forskning och Utveckling in VGR, Vastra Gotaland Region (Id:275357) and Clinical Trials (NCT04729634)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Complications after radical cystectomy for urinary bladder cancer are common. Physical activity after surgery is thought to reduce complications. However, patients with urinary bladder cancer have low levels of physical activity, and interventions supporting physical exercise are needed. This study aimed to evaluate the feasibility of a physical exercise intervention in primary health care. One of the aims of the larger clinical trial will be to reduce complications., Methods: Patients with urinary bladder cancer and who were scheduled for a robotic-assisted radical cystectomy were recruited from Karolinska University Hospital, between February and May 2019. The patients had to be mobile, understand Swedish, and live in Stockholm. The exercise programme was conducted at one primary health care setting over 12 weeks. The exercise programme included supervised aerobic and strengthening exercises, which were performed twice a week, as well as daily walks. Feasibility was measured with process feasibility, including eligibility criteria, adherence, and acceptability, and scientific feasibility, including the ability of outcomes to indicate change, safety, and progression in the exercise programme., Results: Ten patients with a median age of 70 years (min 53-max 86) were included. Adherence to all parts of the intervention was not feasible because of patients' postoperative complications, resulting in dropouts. For the patients who took part in the exercise programme, adherence and acceptability for the exercise period were feasible, but the 6-min walk test was not feasible at discharge from the hospital. Physiotherapists in the primary health care setting perceived the process as feasible. Moreover, the ability of outcomes to indicate change and progression in the exercise programme was feasible, meanwhile no adverse events were registered., Conclusions: The exercise intervention was feasible for the patients that took part in the exercise programme, with respect to safety and progression through the exercise programme. Furthermore, this study suggests that some improvements needed to be implemented in the process, prior to the upcoming randomised controlled trial., (© 2024. The Author(s).)

Post-acute COVID-19 (PACS) are associated with cardiovascular dysfunction, especially postural orthostatic tachycardia syndrome (POTS). Patients with PACS, both in the absence or presence of POTS, exhibit a wide range of persisting symptoms long after the acute infection. Some of these symptoms may stem from alterations in cardiovascular homeostasis, but the exact mechanisms are poorly understood. The aim of this study was to provide a broad molecular characterization of patients with PACS with (PACS + POTS) and without (PACS-POTS) POTS compared to healthy subjects, including a broad proteomic characterization with a focus on plasma cardiometabolic proteins, quantification of cytokines/chemokines and determination of plasma sphingolipid levels. Twenty-one healthy subjects without a prior COVID-19 infection (mean age 43 years, 95% females), 20 non-hospitalized patients with PACS + POTS (mean age 39 years, 95% females) and 22 non-hospitalized patients with PACS-POTS (mean age 44 years, 100% females) were studied. PACS patients were non-hospitalized and recruited ≈18 months after the acute infection. Cardiometabolic proteomic analyses revealed a dysregulation of ≈200 out of 700 analyzed proteins in both PACS groups vs. healthy subjects with the majority (> 90%) being upregulated. There was a large overlap (> 90%) with no major differences between the PACS groups. Gene ontology enrichment analysis revealed alterations in hemostasis/coagulation, metabolism, immune responses, and angiogenesis in PACS vs. healthy controls. Furthermore, 11 out of 33 cytokines/chemokines were significantly upregulated both in PACS + POTS and PACS-POTS vs. healthy controls and none of the cytokines were downregulated. There were no differences in between the PACS groups in the cytokine levels. Lastly, 16 and 19 out of 88 sphingolipids were significantly dysregulated in PACS + POTS and PACS-POTS, respectively, compared to controls with no differences between the groups. Collectively, these observations suggest a clear and distinct dysregulation in the proteome, cytokines/chemokines, and sphingolipid levels in PACS patients compared to healthy subjects without any clear signature associated with POTS. This enhances our understanding and might pave the way for future experimental and clinical investigations to elucidate and/or target resolution of inflammation and micro-clots and restore the hemostasis and immunity in PACS., (© 2023.

Home-based interventions are at the center stage of current health care demands. There is a clear need to translate pulmonary rehabilitation into a home-based setting. This 8-week pilot study aimed to determine the feasibility of a home-based physical activity program for participants with chronic obstructive pulmonary disease (COPD) in Sweden. Patients with COPD, aged 40 years or older and clinically stable in the past 3 months, were recruited. The program used a fitness tracker to monitor step count, weekly health coaching calls using motivational interviewing, and video-guided mindful movements. The outcome measures were adherence to the 8-week program's video-guided exercises (number of times videos were watched), adherence to health coaching calls (minimum 8), monthly and daily step count, and quality of life (QoL) using the chronic respiratory questionnaire. Thirteen participants were enrolled, and 12 participants adhered to health coaching calls and step monitoring. We had 643 video-exercise views, which exceeded the minimum standard (576 views). The mean difference comparing total monthly steps from baseline and the 8-week time point was 47,039 steps (95% CI, -113,625 to 1623.5; P =.06). The minimal clinical improvement of 500 daily steps was found for 8 of the patients. No significant improvement was found in the QoL measures and mental health. We found the home-based physical activity program to be a feasible intervention. Patients reported high adherence to tracking step counts, health coaching calls, and video-guided exercise. No improvements in QoL or monthly step count emerged; however, we found high adherence and a positive trend in the number of monthly step counts, and improvements of at least 500 daily step counts improved in most patients with this small sample size., Competing Interests: All authors have no conflict of interest., (© 2023 The Authors.)

Background: Early mobilisation is strongly recommended following abdominal cancer surgery, but evidence on how to structure early mobilisation to improve outcomes and support patient adherence is lacking. Pedatim® (Phystec) is a novel digital tool designed to support mobilisation in hospital settings using prescribed activities and goals on a tablet. The aim of this study was to evaluate the feasibility of the Pedatim tablet to enhance mobilisation following abdominal cancer surgery., Methods: In a non-randomised feasibility trial design, participants were recruited between January and May 2022 at Karolinska University Hospital, Sweden. Participants used a Pedatim tablet from postoperative day 1 (POD 1) until hospital discharge. The primary objective was to evaluate process feasibility, regarding recruitment, compliance, and acceptability. Recruitment was measured by percentage of available patients included, eligibility criteria sufficiency, and number of dropouts. Compliance was measured by number of patients using versus not using the board. Acceptability was measured using the System Usability Scale. The secondary objective was to evaluate scientific feasibility, defined as an indication of treatment effects where physical activity was assessed using an activPAL accelerometer. Unforeseen events relating to the tablet were also registered., Results: Based on predetermined feasibility criteria, the overall study design was determined to be feasible regarding recruitment as 69% accepted participation (n = 20), compliance was 95%, and the acceptability mean score was high (77/100). Eligibility criteria were not feasible as 79% (n = 108) of available patients were excluded. The intervention was determined to be scientifically feasible, mean steps per day increased from 623 (SD 766) to 1823 (SD 1446), and mean sit-to-stand transitions per day increased from 11 (SD 8) to 29 (SD 12) POD 1-4. Technical issues emerged, highlighting the need for available technical support and "user champions" among healthcare professionals on the ward., Conclusions: Using the Pedatim tablet to enhance mobilisation following abdominal cancer surgery was deemed feasible, but a randomised controlled trial is needed to determine the tool's effectiveness. The study process was determined to be feasible with revisions of the eligibility criteria needed before a future trial. Involving healthcare professionals and providing available technical support are important for future implementation., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Background: Epidemics have historically been accompanied by stigma and discrimination. Disease-related stigma has often been shown to have severe consequences for physical, mental and social wellbeing and lead to barriers to diagnosis, treatment and prevention. The aims of this study were to investigate if a HIV-related stigma measure could be adapted and valid and reliable to measure COVID-19-related stigma, and also to investigate levels of self-reported stigma and related factors among people in Sweden with experience of COVID-19 and compare levels of COVID-19-related stigma versus HIV-related stigma among persons living with HIV who had experienced a COVID-19 event., Methods: Cognitive interviews (n = 11) and cross-sectional surveys were made after the acute phase of the illness using a new 12-item COVID-19 Stigma Scale and the established 12-item HIV Stigma Scale in two cohorts (people who had experienced COVID-19 (n = 166/209, 79%) and people living with HIV who had experienced a COVID-19 event (n = 50/91, 55%). Psychometric analysis of the COVID-19 Stigma Scale was performed by calculating floor and ceiling effects, Cronbach's α and exploratory factor analysis. Levels of COVID-19 stigma between groups were analysed using the Mann-Whitney U test. Levels of COVID-19 and HIV stigma among people living with HIV with a COVID-19 event were compared using the Wilcoxon signed-rank test., Results: The COVID-19 cohort consisted of 88 (53%) men and 78 (47%) women, mean age 51 (19-80); 143 (87%) living in a higher and 22 (13%) in a lower income area. The HIV + COVID-19 cohort consisted of 34 (68%) men and 16 (32%) women, mean age 51 (26-79); 20 (40%) living in a higher and 30 (60%) in a lower income area. The cognitive interviews showed that the stigma items were easy to understand. Factor analysis suggested a four-factor solution accounting for 77% of the total variance. There were no cross loadings, but two items loaded on factors differing from the original scale. All subscales had acceptable internal consistency, showed high floor and no ceiling effects. There was no statistically significant difference between COVID-19 stigma scores between the two cohorts or between genders. People living in lower income areas reported more negative self-image and concerns about public attitudes related to COVID-19 than people in higher income areas (median score 3 vs 3 and 4 vs 3 on a scale from 3-12, Z = -1.980, p = 0.048 and Z = -2.023, p = 0.024, respectively). People from the HIV + COVID-19 cohort reported more HIV than COVID-19 stigma., Conclusions: The adapted 12-item COVID-19 Stigma Scale may be valid and reliable for measurement of COVID-19-related stigma. However, specific items may need to be rephrased or replaced to better correspond to the COVID-19 context. People who had experienced COVID-19 reported low levels of COVID-19-related stigma in general but people from lower income areas had higher levels of negative self-image and concerns about public attitudes related to COVID-19 than people from areas with higher income, which may call for targeted interventions. Although exhibiting more pronounced HIV stigma levels, people living with HIV who had experienced COVID-19 reported COVID-19-related stigma of the same low magnitude as their peers not living with HIV., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Reinius et al.

Background: With ~ 50 million individuals suffering from post-COVID condition (PCC), low health related quality of life (HRQoL) is a vast problem. Common symptoms of PCC, that persists 3 months from the onset of COVID-19 are fatigue, shortness of breath and cognitive dysfunction. No effective treatment options have been widely adopted in clinical practice. Hyperbaric oxygen (HBO 2 ) is a candidate drug., Methods: The objective of this interim analysis is to describe our cohort and evaluate the safety of HBO 2 for post covid condition. In an ongoing randomised, placebo-controlled, double blind, clinical trial, 20 previously healthy subjects with PCC were assigned to HBO 2 or placebo. Primary endpoints are physical domains in RAND-36; Physical functioning (PF) and Role Physical (RP) at 13 weeks. Secondary endpoints include objective physical tests. Safety endpoints are occurrence, frequency, and seriousness of Adverse Events (AEs). An independent data safety monitoring board (DSMB) reviewed unblinded data. The trial complies with Good Clinical Practice. Safety endpoints are evaluated descriptively. Comparisons against norm data was done using t-test., Results: Twenty subjects were randomised, they had very low HRQoL compared to norm data. Mean (SD) PF 31.75 (19.55) (95% Confidence interval; 22.60-40.90) vs 83.5 (23.9) p < 0.001 in Rand-36 PF and mean 0.00 (0.00) in RP. Very low physical performance compared to norm data. 6MWT 442 (180) (95% CI 358-525) vs 662 (18) meters p < 0.001. 31 AEs occurred in 60% of subjects. In 20 AEs, there were at least a possible relationship with the study drug, most commonly cough and chest pain/discomfort., Conclusions: An (unexpectedly) high frequency of AEs was observed but the DSMB assessed HBO 2 to have a favourable safety profile. Our data may help other researchers in designing trials. Trial Registration ClinicalTrials.gov: NCT04842448. Registered 13 April 2021, https://clinicaltrials.gov/ct2/show/NCT04842448 .

Background: This multicentre study explores the effects of pre-operative exercise on physical fitness, post-operative complications, recovery, and health-related quality of life in older individuals with low pre-operative physical capacity scheduled to undergo surgery for colorectal cancer. We hypothesise that this group of patients benefit from pre-operative exercise in terms of improved pre-operative physical function and lower rates of post-operative complications after surgery compared to usual care. Standardised cancer pathways in Sweden dictate a timeframe of 14-28 days from suspicion of cancer to surgery for colorectal cancer. Therefore, an exercise programme aimed to enhance physical function in the limited timeframe requires a high-intensity and high-frequency approach., Methods: Participants will be included from four sites in Stockholm, Sweden. A total of 160 participants will be randomly assigned to intervention or control conditions. Simple randomisation (permuted block randomisation) is applied with a 1:1 allocation ratio. The intervention group will perform home-based exercises (inspiratory muscle training, aerobic exercises, and strength exercises) supervised by a physiotherapist (PT) for a minimum of 6 sessions in the pre-operative period, complemented with unsupervised exercise sessions in between PT visits. The control group will receive usual care with the addition of advice on health-enhancing physical activity. The physical activity behaviour in both groups will be monitored using an activity monitor. The primary outcomes are (1) change in physical performance (6-min walking distance) in the pre-operative period and (2) post-operative complications 30 days after surgery (based on Clavien-Dindo surgical score)., Discussion: If patients achieve functional benefits by exercise in the short period before surgery, this supports the implementation of exercise training as a clinical routine. If such benefits translate into lower complication rates and better post-operative recovery or health-related quality of life is not known but would further strengthen the case for pre-operative optimisation in colorectal cancer., Trial Registration: ClinicalTrials.gov NCT04878185.

Introduction: Long COVID-19, where symptoms persist 12 weeks after the initial SARS-CoV-2-infection, is a substantial problem for individuals and society in the surge of the pandemic. Common symptoms are fatigue, postexertional malaise and cognitive dysfunction. There is currently no effective treatment and the underlying mechanisms are unknown, although several hypotheses exist, with chronic inflammation as a common denominator. In prospective studies, hyperbaric oxygen therapy (HBOT) has been suggested to be effective for the treatment of similar syndromes such as chronic fatigue syndrome and fibromyalgia. A case series has suggested positive effects of HBOT in long COVID-19. This randomised, placebo-controlled clinical trial will explore HBOT as a potential treatment for long COVID-19. The primary objective is to evaluate if HBOT improves health-related quality of life (HRQoL) for patients with long COVID-19 compared with placebo/sham. The main secondary objective is to evaluate whether HBOT improves endothelial function, objective physical performance and short-term HRQoL., Methods and Analysis: A randomised, placebo-controlled, double-blind, phase II clinical trial in 80 previously healthy subjects debilitated due to long COVID-19, with low HRQoL. Clinical data, HRQoL questionnaires, blood samples, objective tests and activity metre data will be collected at baseline. Subjects will be randomised to a maximum of 10 treatments with hyperbaric oxygen or sham treatment over 6 weeks.

Objective: The aim of this study was to investigate if mobilization out of bed, within 2 hours after abdominal surgery, improved participants' respiratory function and whether breathing exercises had an additional positive effect., Methods: Participants were 214 consecutively recruited patients who underwent elective open or robot-assisted laparoscopic gynecological, urological, or endocrinological abdominal surgery with an anesthetic duration of >2 hours. They were recruited to a randomized controlled trial. Immediately after surgery, patients were randomly assigned to 1 of 3 groups: mobilization (to sit in a chair) and standardized breathing exercises (n = 73), mobilization (to sit in a chair) only (n = 76), or control (n = 65). The interventions started within 2 hours after arrival at the postoperative recovery unit and continued for a maximum of 6 hours. The primary outcomes were differences in peripheral oxygen saturation (SpO2, as a percentage) and arterial oxygen pressure (PaO2, measured in kilopascals) between the groups. Secondary outcomes were arterial carbon dioxide pressure, spirometry, respiratory insufficiency, pneumonia, and length of stay., Results: Based on intention-to-treat analysis (n = 214), patients who received mobilization and breathing exercises had significantly improved SpO2 (mean difference [MD] = 2.5%; 95% CI = 0.4 to 4.6) and PaO2 (MD = 1.40 kPa; 95% CI = 0.64 to 2.17) compared with the controls. For mobilization only, there was an increase in PaO2 (MD = 0.97 kPa; 95% CI = 0.20 to 1.74) compared with the controls. In the per-protocol analysis (n = 201), there were significant improvements in SpO2 and PaO2 for both groups receiving mobilization compared with the controls. Secondary outcome measures did not differ between groups., Conclusion: Mobilization out of bed, with or without breathing exercises, within 2 hours after elective abdominal surgery improved SpO2 and PaO2., Impact: The respiratory effect of mobilization (out of bed) immediately after surgery has not been thoroughly evaluated in the literature. This study shows that mobilization out of bed following elective abdominal surgery can improve SpO2 and PaO2., Lay Summary: Mobilization within 2 hours after elective abdominal surgery, with or without breathing exercises, can improve patients' respiratory function., (© The Author(s) 2021.

Objective: Early mobilization is advocated for patients going through abdominal surgery; however, little is known about the patient experience of being mobilized immediately after surgery. The purpose of this study was to explore patient experiences of mobilization immediately after elective abdominal cancer surgery., Methods: This interview study used qualitative content analysis. With the use of purposeful sampling, a total of 23 participants who had been mobilized immediately after abdominal surgery were recruited at a university hospital in Stockholm, Sweden. Individual face-to-face interviews were conducted within 1 to 4 days after surgery and took place at the surgical ward where the participants were treated. A semi-structured guide was used. All interviews were audio recorded and transcribed verbatim., Results: The content analysis revealed 3 categories that emerged into 1 overarching theme: "to do whatever it takes to get home earlier." The participants experienced that mobilization out of bed had an impact on their physical and mental well-being. Motivation and the experiences of themselves and others were factors that affected patient attitudes toward early mobilization. Preparation and competent caregivers were emphasized as important factors that enabled the patient to feel safe and confident during mobilization., Conclusions: Patients experienced mobilization as an important part of the care that had an impact on recovery and well-being, physically as well as mentally, both immediately and over time., Impact: As this is the first study to our knowledge to investigate patient experiences of mobilization immediately after abdominal surgery, this information can be used to support the development of early mobilization protocols in hospital settings., (© The Author(s) 2020.

Background: Patients who have undergone radical cystectomy for urinary bladder cancer are not sufficiently physically active and therefore may suffer complications leading to readmissions. A physical rehabilitation programme early postoperatively might prevent or at least alleviate these potential complications and improve physical function. The main aim of the CanMoRe trial is to evaluate the impact of a standardised and individually adapted exercise intervention in primary health care to improve physical function (primary outcome) and habitual physical activity, health-related quality of life, fatigue, psychological wellbeing and readmissions due to complications in patients undergoing robotic-assisted radical cystectomy for urinary bladder cancer., Methods: In total, 120 patients will be included and assigned to either intervention or control arm of the study. All patients will receive preoperative information on the importance of early mobilisation and during the hospital stay they will follow a standard protocol for enhanced mobilisation. The intervention group will be given a referral to a physiotherapist in primary health care close to their home. Within the third week after discharge, the intervention group will begin 12 weeks of biweekly exercise. The exercise programme includes aerobic and strengthening exercises. The control group will receive oral and written information about a home-based exercise programme. Physical function will serve as the primary outcome and will be measured using the Six-minute walk test. Secondary outcomes are gait speed, handgrip strength, leg strength, habitual physical activity, health-related quality of life, fatigue, psychological wellbeing and readmissions due to complications. The measurements will be conducted at discharge (i.e. baseline), post-intervention and 1 year after surgery. To evaluate the effects of the intervention mixed or linear regression models according to the intention to treat procedure will be used., Discussion: This proposed randomised controlled trial has the potential to provide new knowledge within rehabilitation after radical cystectomy for urinary bladder cancer. The programme should be easy to apply to other patient groups undergoing abdominal surgery for cancer and has the potential to change the health care chain for these patients., Trial Registration: ClinicalTrials.gov.

Preoperative physical exercise is emerging as a growing field of research globally. There are still challenges in recruiting vulnerable older people, and time constraints in preoperative cancer care to consider. We therefore evaluated the feasibility of short-term supervised home-based exercise in older people prior to colorectal cancer surgery. This feasibility study was conducted between September 2016 and June 2018. People ≥70 years scheduled for colorectal cancer surgery were recruited and randomized to an intervention group receiving supervised home-based physical exercise at a high level of estimated exertion or a standard care group following the standard preoperative path. The exercise (respiratory, strength, and aerobic) consisted of 2-3 supervised sessions a week in the participants' homes, for at least 2-3 weeks or until surgery, and a self-administered exercise program in between. The primary outcome was process feasibility, including aspects specifically related to recruitment rate, compliance to the intervention, and acceptability. The secondary outcome was scientific feasibility including treatment safety, description of dose level and response, and estimation of treatment results. Twenty-three participants were included (recruitment rate 35%). A median of 6 supervised sessions was conducted over a 17-day exercise period. Compliance with the supervised sessions was 97%, and participants found the intervention acceptable. Concerning the self-administered exercise, a median of 19 inspiratory muscle training, 6 functional strength, and 8.5 aerobic sessions were reported. Challenges reported by program instructors were time constraints and difficulties in achieving high exercise intensities on the Borg CR-10 scale. A statistically significant between-group difference was only found in inspiratory muscle strength, favoring the intervention group (p<0.01). A short-term preoperative supervised home-based physical exercise intervention can be conducted, with respect to compliance and acceptability, in older people with similar physical status as in this study prior to colorectal cancer surgery. However, modifications are warranted with respect to improving recruitment rates and achieving planned intensity levels prior to conducting a definitive trial., Competing Interests: The authors have declared that no competing interests exist.

Objective: There is a need for simple tools to evaluate physical performance in patients with COPD before and after pulmonary rehabilitation. The aims of this study were to evaluate changes in short physical performance battery (SPPB)-scores in patients with COPD after a 4-week pulmonary rehabilitation program; explore possible relationships between SPPB-scores and exercise capacity (6-min walk distance), dyspnea (modified Medical Research Council's dyspnea scale), disease-specific quality of life (COPD assessment test), and pulmonary function (predicted forced expiratory volume in one second) at baseline; and explore if changes in SPPB-scores are related to changes in exercise capacity, dyspnea, and disease-specific quality of life following pulmonary rehabilitation., Results: Forty-five patients with COPD were included in the final analysis. SPPB-scores improved following pulmonary rehabilitation (mean change: 1.2 ± 1.7 points, p < 0.001). There were moderate correlations between SPPB-scores and exercise capacity (r = 0.50, p < 0.001) and dyspnea (r = - 0.45, p = 0.003) at baseline, but not with pulmonary function or disease-specific quality of life. Changes in SPPB-scores were not associated with changes in exercise capacity or dyspnea scores. The SPPB may be a useful tool for evaluating physical performance in COPD Trial registration ClinicalTrials.gov NCT02314338, December 11, 2014.

Objectives: To evaluate acute effects of glossopharyngeal insufflation (GI) on lung function, airway pressure (P aw ), blood pressure and heart rate (HR) in people with cervical spinal cord injury (CSCI)., Design: Case-control design., Setting: Karolinska Institutet, Stockholm, Sweden., Participants: Ten participants with CSCI suffering from lesions between C4 and C8, and ASIA classification of A or B were recruited. Ten healthy particpants familiar with GI were recruited as a reference group., Outcome Measures: Spirometry, mean arterial blood pressure (MAP), P aw, and HR were measured in a sitting and a supine position before, during, and after GI., Results: GI in the study group in a sitting position increased total lung capacity (TLC) by 712 ml: P < 0.001, vital capacity (VC) by 587 ml: P < 0.0001, P aw by 13 cm H 2 O: P < 0.01, and HR by 10 beats/min: P < 0.001. MAP decreased by 25 mmHg, P < 0.0001. Significant differences were observed between groups comparing baseline with GI. The reference group had a higher increase in; TLC (P < 0.01), VC (P < 0.001), P aw (P < 0.001) and HR (P < 0.05) and a higher decrease in MAP (P < 0.001). With GI in a sitting compared to a supine position, TLC, MAP, HR, P aw remained unchanged in the study group, while residual volume decreased in the supine position (P < 0.01)., Conclusion: There was a difference between the groups in the increase in TLC; VC; P aw, HR and in the decrease in MAP with GI, however MAP, HR and P aw responded in similar way in both groups in a sitting as well as a supine position. If performed correctly, the risks of GI resulting in clinically significant hemodynamic changes is low, although syncope may still occur.

In Ankylosing Spondylitis (AS), thoracic range of motion is often greatly limited. The objective of the study was to describe the effects of 12 weeks of Glossopharyngeal Insufflation (GI) training in patients with AS. Dynamic spirometry included vital capacity, forced expiratory volume, and peak expiratory flow. Thoracic and lumbar range of motion was assessed by tragus-to-wall distance, modified Schober test, and tape measure. Disease activity, activity limitation, and health perception were assessed using the BAS-Indices, and tension in the thoracic region during GI was assessed using the Borg CR-10 scale. Adherence to training was recorded in an activity log, along with any remarks on the training. Ten patients were recruited and six male patients fulfilled the study protocol. Three patients were able to learn GI by exceeding their maximal vital capacity with 5% using GI. A significant increase in thoracic range of motion both on costae IV (P = 0.04) and at the level of the xiphoid process (P = 0.04) was seen. Thus, patients with AS can practice GI, it is safe if maximal exertion is avoided, and patients with some mobility in the chest can increase their lung function substantially by performing GI during 12 weeks.

Purpose: To investigate whether sessions of glossopharyngeal pistoning (GP) to lung volumes exceeding maximum inspiratory capacity in a group of extremely well-trained elite swimmers would affect maximum lung volumes and buoyancies., Methods: Ten female and 16 male swimmers performed GP four times a week for 5 wk in addition to their regular swimming training program. Pulmonary function, chest expansion, hydrostatic weights (maximally inhaled and exhaled), and body composition (relative amounts of fat, bone, muscle, and fat-free tissue) were measured., Results: Training compliance was 79% for the males and 82% for the females. Chest expansion increased significantly during the training period, by 1.0 cm and by 0.8 cm at the level of the xiphiod and the fourth costae for the males, and by 0.6 cm and 0.8 cm for the females. The buoyancy lifting force increased significantly by 0.17 and 0.37 kg for the males and the females, respectively. The females also increased their vital capacity significantly by 2%. No significant changes in body composition took place in either group., Conclusion: The lung volumes and buoyancies of swimmers can be increased by sessions of GP.
