Review
The puerperium is a complex period that begins with placental delivery and lasts for 6 weeks, during which readaptation of the female organism and redistribution of blood volume occur. This period is conducive to the occurrence of thromboembolic events. In the context of the SARS-CoV-2 pandemic, the virus responsible for COVID-19, the attention of the scientific community and health professionals has been focused on obtaining insights on different aspects of this disease, including etiology, transmission, diagnosis, and treatment. Regarding the pregnancy-postpartum cycle, it is opportune to review the clinical conditions that can occur during this period and to investigate dyspnea as a postpartum symptom in order to avoid its immediate association with COVID-19 without further investigation, which can lead to overlooking the diagnosis of other important and occasionally fatal conditions.

Randomized Controlled Trial
Does mechanical threshold inspiratory muscle training promote recovery and improve outcomes in patients who are ventilator-dependent in the intensive care unit? The IMPROVE randomised trial.
BACKGROUND
In patients who are ventilator-dependent in the intensive care unit, inspiratory muscle training may improve inspiratory muscle strength and accelerate liberation from the ventilator, but optimal training parameters are yet to be established, and little is known about the impact of inspiratory muscle training on quality of life or dyspnoea. Thus, we sought to ascertain whether inspiratory muscle training, commenced while ventilator-dependent, would improve outcomes for patients invasively ventilated for 7 days or longer.
METHODS
In this randomised trial with assessor blinding and intention-to-treat analysis, 70 participants (mechanically ventilated ≥7 days) were randomised to receive once-daily supervised high-intensity inspiratory muscle training with a mechanical threshold device in addition to usual care or to receive usual care (control). Primary outcomes were inspiratory muscle strength (maximum inspiratory pressure % predicted) and endurance (fatigue resistance index) at ventilator liberation and 1 week later. Secondary outcomes included quality of life (SF-36v2, EQ-5D), dyspnoea, physical function, duration of ventilation, and in-hospital mortality.
RESULTS
Thirty-three participants were randomly allocated to the training group, and 37 to the control group. There were no statistically significant differences in strength (maximum inspiratory pressure) (95% confidence interval [CI]: -7.4 to 14.0) or endurance (fatigue resistance index) (95% CI: -0.003 to 0.436). Quality of life improved significantly more in the training group than in the control group (EQ-5D: 17.2; 95% CI: 1.3-33.0) (SF-36-PCS: 6.97; 95% CI: 1.96-12.00). Only the training group demonstrated significant reductions in dyspnoea (-1.5 at rest, -1.9 during exercise). There were no between-group differences in duration of ventilation or other measures. In-hospital mortality was higher in the control group than in the training group (9 vs 4, 24% vs 12%, p = 0.23).
CONCLUSIONS
In patients who are ventilator-dependent, mechanical threshold loading inspiratory muscle training improves quality of life and dyspnoea, even in the absence of strength improvements or acceleration of ventilator liberation.

Randomized Controlled Trial
BACKGROUND
COVID-19-related acute respiratory distress syndrome (CARDS) is a severe evolution of the Sars-Cov-2 infection and necessitates intensive care. COVID-19 may subsequently be associated with long COVID, whose symptoms can include persistent respiratory symptoms up to 1 year later. Rehabilitation is currently recommended by most guidelines for people with this condition.
OBJECTIVES
To evaluate the effects of exercise training rehabilitation (ETR) on dyspnoea and health-related quality of life measures in people with continuing respiratory discomfort following CARDS.
METHODS
In this multicentre, two-arm, parallel, open, assessor-blinded, randomised controlled trial, we enroled adults previously admitted with CARDS to 3 French intensive care units who had been discharged at least 3 months earlier and who presented with an mMRC dyspnoea scale score > 1. Participants received either ETR or standard physiotherapy (SP) for 90 days. The primary outcome was dyspnoea, as measured by the Multidimensional Dyspnoea Profile (MDP), at day 0 (inclusion) and after 90 days of physiotherapy. Secondary outcomes were the mMRC and 12-item Short-Form Survey scores.
RESULTS
Between August 7, 2020, and January 26, 2022, 487 participants with CARDS were screened for inclusion, of whom 60 were randomly assigned to receive either ETR (n = 27) or SP (n = 33). Mean MDP following ETR was 42% lower than after SP (26.15 vs. 44.76); a difference of -18.61 (95% CI -27.78 to -9.44; p<10).
CONCLUSION
People who were still suffering from breathlessness three months after being discharged from hospital with CARDS had significantly improved dyspnoea scores when treated with ETR therapy for 90 days unlike those who only received SP. Study registered 29/09/2020 on Clinicaltrials.gov (NCT04569266).

The paper by Nielsen et al in this journal reports the prevalence of dyspnea in 15 countries throughout the world as 27%. Dyspnea is a powerfully aversive sensation frequently overlooked despite its prevalence and the severity of distress it causes. Despite its ‘subjective’ nature, dyspnea is a powerful predictor of morbidity and mortality. We suggest that this is because the information provided by enteroceptors is so rich that it is as valuable as the more precise but relatively sparse information provided by clinical tests. Relatively simple measures of dyspnea, such as the Medical Research Council Breathlessness Scale used by Nielsen et al, can provide meaningful information at very little cost.

In his case report, a 74-year-old physically fit man was evaluated repeatedly for several years in the cardiology department due to dyspnoea on exertion (DOE). Several standard cardiac and pulmonary tests were performed but did not provide sufficient cause for the DOE. Lastly, the patient was evaluated with a cardiopulmonary exercise test (CPET) with simultaneous in- and expiratory gas sampling. The test revealed a low aerobic capacity due to chronotropic incompetence (CI), thus explaining the DOE. Subsequently, the patient was treated with a rate-responsive pacemaker. CPET-is an ideal test for diagnosing CI.

Review
Dyspnoea is a principal presenting symptom in pulmonary arterial hypertension (PAH), and often the most distressing. The pathophysiology of PAH is relatively well understood, with the primary abnormality of pulmonary vascular disease resulting in a combination of impaired cardiac output on exercise and abnormal gas exchange, both contributing to increased ventilatory drive. However, increased ventilatory drive is not the sole explanation for the complex neurophysiological and neuropsychological symptom of dyspnoea, with other significant contributions from skeletal muscle reflexes, respiratory muscle function, and psychological and emotional status. In this review, we explore the physiological aspects of dyspnoea in PAH, both in terms of the central cardiopulmonary abnormalities of PAH and the wider, systemic impact of PAH, and how these interact with common comorbidities. Finally, we discuss its relationship with disease severity.

BACKGROUND
Lymphangioleiomyomatosis (LAM) is associated with progressive dyspnoea and exercise intolerance, but despite the central role of physiotherapy on pulmonary rehabilitation, there is a huge lack of physiotherapy approaches used specifically for LAM patients.
OBJECTIVE
to identify the physiotherapeutic strategies used in the treatment of patients with LAM.
MATERIALS AND METHODS
This is a systematic review of literature. Searches were performed (in PubMed, Lilacs, Embase and PEDro databases) with the keywords "Lymphangioleiomyomatosis" and "Physiotherapy," and its variations. Articles describing physiotherapy interventions were included in the study. Data extracted from the studies were authors, year, country of publication, sample size, physiotherapy intervention, time/frequency/duration of intervention protocols, instruments used to measure results and main findings. Methodological quality of studies was evaluated by PEDro Scale (clinical trials), Newcastle-Ottawa Scale (NOS; observational studies) and CARE checklist (case reports), respectively.
RESULTS
A total of 82 articles identified, three duplicates were removed, 71 studies were excluded after title and abstract reading and four after full-text reading, all due to absence of association with the study topic. Four studies were included in the present review. Cardiorespiratory physiotherapy with endurance and resistance training were identified as physiotherapeutic strategies to improve lung function, functional capacity, depression symptoms and quality of life in LAM.
CONCLUSIONS
Endurance and resistance training is the keystone for physiotherapy in patients with LAM, but despite the reported benefits, there is a huge lack of studies related to the modalities, safety and dosage of physiotherapy prescription for patients with LAM.KEY MESSAGESLymphangioleiomyomatosis (LAM), a rare disease, leads to progressive dyspnoea and exercise intolerance;Physiotherapy can improve dyspnoea and exercise intolerance in LAM through endurance and resistance exercises.

Review
Chronic dyspnoea is a devastating symptom that debilitates millions of people worldwide. It causes a large burden on both patient and carer, and significant costs to society and health services. Treatment options are limited. Much effort has been directed at optimising lung function and improving exercise capacity, however, the brain mechanisms underlying dyspnoea perception have received less attention. In this review, we focus on cognitive and affective aspects of dyspnoea and discuss how novel neuroimaging methods can provide quantitative measures of these subjective sensations. We draw parallels with the more advanced field of chronic pain, and explain some of the challenges faced when imaging dyspnoea. To date, brain mechanisms of dyspnoea have been investigated in a handful of studies by a limited number of authors. These have found consistent activation in the insular cortex, the anterior cingulate cortex and the amygdala. Novel neuroimaging methods and an improved understanding of perceptual mechanisms underlying dyspnoea now position us to transform dyspnoea research. Future research should investigate how brain regions associated with dyspnoea interact, as well as accurately correlate this neuronal activation with reliable behavioural measures. A better understanding of the brain processes underlying dyspnoea perception will lead to new therapies that will improve quality of life for a very large group of patients.
