HPV After chemoRadioTherapy

The HART (HPV After chemoRadiotherapy) study is a prospective multicenter observational trial designed to evaluate the clinical utility of HPV testing in the follow-up of patients treated with definitive chemoradiotherapy (CRT) for cervical cancer. Current surveillance after CRT relies mainly on clinical examination and imaging, while the role of HPV-based molecular monitoring remains insufficiently defined. The study plans to enroll 120 patients with FIGO stage IB-IVA cervical cancer treated with primary radiotherapy with curative intent. HPV detection will be performed using two complementary approaches: PCR-based detection of HPV DNA from a cervical swab and analysis of circulating HPV tumor DNA (ctDNA) in peripheral blood. Samples will be collected before treatment and during follow-up at 3, 12, and 24 months after completion of CRT. The primary objective is to determine the sensitivity of these methods for detecting disease recurrence during a two-year follow-up period. Secondary objectives include evaluation of HPV clearance after treatment, comparison of HPV genotypes before and after therapy in cases of persistence, and comparison of the diagnostic performance of cervical HPV testing and ctDNA detection. The study aims to generate evidence supporting the integration of HPV-based molecular monitoring into routine follow-up, potentially enabling earlier detection of recurrence and more individualized surveillance strategies for patients after CRT for cervical cancer.

Expiratory Muscle Training in Parkinson's Disease With Forward Trunk Flexion

Postural abnormalities (PA) negatively affecting the axial system are part of the symptoms of Parkinson's disease (PD). They occur in more than 20% of patients with PD especially in more advanced stages of the disease, contribute significantly to patient disability, affect respiratory functions, and reduce quality of life. Eighty-five percent of patients with forward trunk flexion (FTF) reported difficulties with swallowing (dysphagia), shortness of breath, and drooling. Previous studies in patients with PD also identified cough disorders (dystussia). Since cough and properly functioning swallowing are key mechanisms for airway protection, impairments in these functions lead to a higher risk of aspiration. The seriousness of this problem is clearly confirmed by the fact that aspiration pneumonia is the leading cause of death in patients with PD. Among non-pharmacological interventions for airway protection, expiratory muscle strength training (EMST) has been shown to be beneficial in patients with PD. Recent randomized controlled studies demonstrated a significant effect of EMST on dysphagia, dystussia, drooling, and dysarthria in patients with PD. However, the literature lacks data on the effect of EMST on dystussia in patients with PD and FTF, who, according to previous research, are also affected by restrictive ventilatory impairment, which negatively affects respiratory capacity and, in particular, cough strength. The aim of this study is to evaluate the effect of EMST on cough, swallowing, respiratory muscle strength, and drooling in patients with PD and forward trunk flexion.

Effect of Visual Feedback From the SpiroGym Mobile Application

The previous pilot study showed that two weeks of intensive expiratory muscle strength training (EMST) with SpiroGym was sufficient to significantly improve voluntary peak cough flow (PCF). The improvement was quantitatively comparable to that reported in other intensive EMST studies of longer duration. To explain this rapid improvement, we considered the potential contribution of SpiroGym's visual feedback. We assumed that real-time visual feedback increased training effort compared with conventional EMST performed without immediate feedback. The aim of this study is to evaluate the effect of visual feedback provided by the SpiroGym mobile application on performance during expiratory muscle strength training in patients with Parkinson's disease.

Expiratory Muscle Training and Trunk Flexion in Parkinson's Disease

Postural abnormalities involving the trunk are prevalent in over 20% of patients with Parkinson's disease (PD). Pathological forward trunk flexion (FTF) is a drug-refractory complication in patients with PD leading to imbalance, pain and fall-related injuries. Deep abdominal muscle training is a key rehabilitation strategy for FTF, as muscles like the transversus abdominis and multifidus are crucial for lumbar stabilization. This training has been shown to improve body position and lumbar proprioception. Abdominal muscles are also responsible for forced expiration. Expiratory muscle strength training (EMST) utilizing forced expiration through expiratory trainer has emerged as a beneficial intervention in the non-pharmacological management of PD, positively impacting clinical aspects such as dysphagia, dystussia, hypokinetic dysarthria, and drooling. EMG study showed large abdominal muscles activity, particularly the transversus abdominis and internus obliquus abdominis during EMST. Therefore, EMST might also be effective in improving lumbar stabilization. Given the established role of abdominal muscles in trunk stabilization, it is plausible that activation of deep abdominal muscles during EMST with the right level of resistance might improve FTF in PD patients. No studies have yet examined the effect of EMST on posture in PD. The primary aim of this study will be to evaluate the effect of EMST on forward trunk flexion in patients with Parkinson's disease. The secondary aim will be to assess the potential duration of the EMST effect on postural abnormalities and its impact on patient stability.

Effect of Trunk Flexion on Airway Defense in Parkinson's Disease

The main mechanisms of airway protection include a properly functioning swallowing process and a cough. Studies focusing on patients with Parkinson's disease (PD) have previously demonstrated impairments in both swallowing (dysphagia) and coughing (dystussia). Aspiration pneumonia is the leading cause of death in individuals with PD. Swallowing function is directly related to body posture. Postural abnormalities (PA) are a common symptom of PD and significantly contribute to patient disability, affect respiratory function, and reduce quality of life. Previous research has shown that more than 20% of PD patients suffer from some form of PA. Most PD patients with a forward trunk flexion angle greater than 30 degrees report specific difficulties, such as dysphagia. A link has previously been demonstrated between postural abnormalities associated with flexed posture and restrictive ventilatory impairment. It can be assumed that this restrictive ventilatory impairment, which reduces the amount of air the patient can inhale into the lungs and subsequently exhale, negatively affects the strength of voluntary cough. However, this hypothesis has not yet been verified in the mentioned patient group. The primary aim of the study will be to examine the effect of forward trunk flexion (FTF) in Parkinson's disease on the airway defense system.

SpiroGym App-Aided Cough Rehabilitation

The pilot study by Srp et al. (2021) proved that the SpiroGym app was feasible for supporting expiratory muscle strength training (EMST) in Parkinson's disease (PD) patients. Two weeks of intensive EMST coupled with SpiroGym were sufficient to significantly improve the participants' voluntary peak cough flow (PCF). The improvement was quantitatively comparable to the results of other intensive EMST studies with longer durations. When interpreting such rapid improvement, the impact of SpiroGym's visual feedback was considered. It was assumed that visual feedback increased training effort compared to regular training without immediate control. However, comparative studies were required to verify the possible additional effects of visual feedback on voluntary PCF compared to EMST without feedback.
