Filter by:Obesity Hypoventilation Syndrome(OHS) is characterized by daytime hypercapnia and sleep-disordered breathing without other causes of hypoventilation in individuals with a body mass index above 30 kg/m2. It is stated that obesity is at the basis of the metabolic changes seen in individuals diagnosed with OHS. Also sedentary lifestyle habits, which are common in obese individuals, cause the risk of sarcopenia due to loss of muscle strength and mass, accumulation of adipose tissue in the body, and decreased exercise capacity. Reduced exercise capacity due to obesity has been shown in the literature to strongly interact with mortality risk. As a result of obesity and all this negative picture, impaired emotional state and decreased quality of life are observed in individuals. Simultaneously, sleep parameters are also negatively affected. In particular, increased adipose tissue leads to loss of muscle mass and strength, increased risk of sarcopenia and sleep-related problems. The association of obesity and sarcopenia is referred to as 'sarcopenic obesity'. Sarcopenic obesity is defined as the coexistence of sarcopenia and obesity. The concept of sarcopenic obesity has recently taken its place in the literature. In particular, there are very few studies on its relationship with sleep parameters. However, while obesity is the basis of OHS, there are no studies on the presence and effects of sarcopenic obesity in this patient group. Based on this point, we aim to investigate the effects of sarcopenic obesity on sleep parameters, exercise capacity and quality of life in individuals with OHS.
Sleep apnea-hypopnea syndrome is a sleep-related respiratory disorder characterized by partial or total interruptions in breathing during sleep. The majority of syndromes involve an obstructive mechanism (OSA), caused by a reduction in the caliber of the upper airway (UA), most often associated with hypotonia of the surrounding muscles, preventing air from entering the UA during inspiration (1). The clinical consequences of this syndrome are excessive fatigue and daytime sleepiness, which have a negative impact on the quality of life of patients. (2,3) Despite the positive results on apnea-hypopnea index and daytime sleepiness of continuous positive airway pressure (today's reference treatment), its 3-year compliance rate (i.e 59.9% according to a study by Abdelghani et al (4) points to the need to develop other associated therapies. Several studies have demonstrated the efficacy of physiotherapy, such as physical activity and oro-pharyngeal muscle strengthening, notably on the apnea-hypopnea index and daytime sleepiness measured by the Epworth scale (5,6). Few studies have investigated the effect of inspiratory muscle training (IMT), even though the use of the inspiratory musculature (i.e. the diaphragm) is a means of supplementing the peri-pharyngeal muscles, as it helps to maintain the permeability of the upper airways (7-9). Inspiratory muscle training (IMT) could therefore be considered as part of the physiotherapeutic management of the OSA. The heterogeneity of current results concerning IMT in OSA , but above all the lack of evidence that it is dangerous, means that new clinical studies could be carried out in an attempt to demonstrate its efficacy. Our research hypothesis is therefore as follows: Implementing an inspiratory muscle strengthening protocol in patients suffering from OSA can reduce daytime sleepiness.

Pulmonary hypertension (PH) has three main types, pre-capillary PH, post-capillary PH, and combined pre-capillary and post-capillary PH, and it is based on mean pulmonary arterial pressure (PAP) > 20 mmHg measured with a right heart catheterization (RHC). Chronic thromboembolic pulmonary hypertension (CTEPH) is mainly defined as a pre-capillary PH and classed as a Group IV PH. It was reported that 0.1-9.1% of individuals with pulmonary embolism develop CTEPH within two years after the initial diagnosis, and CTEPH is the only PH category that has a chance of being cured, mainly by pulmonary endarterectomy. Sleep-related breathing disorders (SRBD) are defined as obstructive sleep apnea (OSA) disorders, central sleep apnea (CSA) syndromes, sleep-related hypoventilation disorders, and sleep-related hypoxemia. An SRBD may also lead to an increase in PAP primarily during sleep and cause nocturnal hypoxemia. Although SRBDs were reported in patients with pre-capillary PH, most of the studies included patients with idiopathic PAH. Although the cause-and-effect relationship between pre-capillary PH and SRBDs is uncertain, it is known that mPAP may increase during sleep in patients with OSA . Less is known regarding the occurrence of SRBDs in CTEPH. Previously a few study showed relationship between SRBDs an CTEPH as the main type was OSA. Most of the studies evaluated preoperative occurance and incidance of SRBDs in CTEPH. Only one study performed post operative SRBD on a cardiorespiratory device was conducted the night before and one month after elective pulmonary endarterectomy. In our previous study we showed that severe nocturnal hypoxemia (NH) is highly prevelant in preoperative CTEPH patients and the most common two types of SRBD are OSA and isolated sleep related hypoxemia (ISRH) and age, mPAP and AHI are independent determinants of severe NH. (J. Clin. Med. 2023, 12, 4639 https://doi.org/10.3390/jcm12144639) In this present study we aimed to investigate occurrence of SRBDs and mortality 5 years after pulmonary endarterectomy operation.
This study is a randomized controlled trial to evaluate whether EEG-guided calibration of inhalation agents can reduce occurrence of EEG discontinuity in infants during general anesthesia.
(1) Maximum respiratory pressure (MRP)1) Maximum inspiratory pressure (maximum intake pressure) and maximum expiratory pressure (MEP) Digital spirometer (Pony FX, COSMED Inc., Italy) are used to measure the micro-paste in a seated position. MIP is based on the pressure maintained for at least 1 second, inhaling or exhaling with maximum effort in the maximum exhalation state (=residual volume) and the maximum exhalation state (=total lung capacity). The maximum positive pressure value of the MEP and the minimum sound pressure value of the MIP are selected among the three or more attempts. 2) Using the MVV (maximum volitional ventilation) Digital spirometer (Pony FX, COSMED Inc., Italy) machine, repeat breathing deeply and quickly for 12 seconds while wearing a nose plug, and multiply it by 5 to obtain the L/min value. (2) Measure the values of the Pneumatic ventilation. · FVC (forced vital capacity): Total expiratory volume of one of the maximum effort gases · FEV1 (forced expiratory volume 1, effort expiratory volume): Ejected expiratory volume of the first second of the maximum effort expiratory volume (FEV1/FVC): FVC ratio, percentage of FVCs, and extraction of the FVC (excessive flow). PEF): Highest speed of effort opportunity
The primary cause of the complex interaction of chronic pelvic pain originates from the visceral organs in the pelvic cavity, and it has been observed that musculoskeletal dysfunctions (such as increased muscle activity in the pelvic floor muscles) are often accompanied by visceral painful stimuli in the pelvic region as a result of shared innervation and visceral-somatic convergence. This study aims to investigate the effect of breathing exercises combined with pelvic floor exercises on pain, pelvic floor muscle activity, psychological factors, and quality of life in women with chronic pelvic pain.
This clinical research study will investigate the dose of inspiratory muscle strength training needed to maintain cardiovascular adaptations induced by a six-week loading dose.
Respiratory muscle dysfunction is highly prevalent in patients with prolonged weaning from mechanical ventilation and is strongly associated with weaning failure. Efforts to strengthen the respiratory muscles, aimed at reversing or minimizing the impact of respiratory muscle weakness on clinical outcomes, have generally focused on the diaphragm with specific inspiratory muscle training (IMT) exercises. However, the effectiveness of these exercises and impact on clinical outcomes are not current practice in the majority of ICUs, as they are hardly feasible in ICU patients who often cannot be disconnected from the ventilator and cannot fully cooperate. Promising results have been published concerning non-respiratory training techniques, which can also target the accessory muscles, particularly important in the presence of increased load to the respiratory system, as in the case of the weaning phase. These non-respiratory training techniques would have the advantage of not entailing disconnection of the patient from the ventilator. In particular, in healthy subjects, a quasi-isometric neck contraction, called neck flexion, appeared to generate greater or comparable recruitment of some principal and accessory muscles of respiration, when compared to conventional IMT. However, this has not been studied in patients requiring prolonged mechanical ventilation, for whom IMT with threshold loading devices remains the primary recommended rehabilitation strategy. Therefore, the primary aim of the investigators is to assess the feasibility, tolerability, and safety of neck flexion and to compare them with IMT technique in patients with difficult and prolonged weaning from mechanical ventilation. Secondary aims are: i) to characterize which respiratory muscles are recruited and their level of activation at different levels of ventilatory assistance and ii) to assess which respiratory muscles are recruited and their level of activation during the two techniques and to compare these findings. The hypothesis of the investigators is that neck flexion will be feasible (more than conventional IMT), well tolerated, and safe in patients with difficult and prolonged weaning. The investigators also hypothesize that, reducing the level of assistance and during unassisted breathing, a progressively increasing activation of the diaphragm, neck and trunk respiratory muscles, reflecting increased ventilatory load, will be fund. Finally, the hypothesis of the investigators is that the level of muscle activation/recruitment during neck flexion will be comparable or even greater to that occurring during IMT, as found in healthy subjects. Finding a new and highly feasible rehabilitative technique, able to recruit and train the respiratory muscles (including accessory muscles), will have the potential to promote patients' weaning and improve all related clinical outcomes, and therefore to dramatically shift the paradigm about the role of rehabilitation in ICU.
