Fragility scales are intended to help in therapeutic decisions. Here, we asked if the fragility assessment in MM patients ≥ 75 years old qualified for treatment by the local physician correlates with the choice of treatment: a two- or three-drug regimens. Between 7/2018 and 12/2019, we prospectively enrolled 197 MM patients at the start of treatment from the 13 Polish Myeloma Group centers. The data to assess fragility were prospectively collected, but centrally assessed fragility was not disclosed to the local center. The activity of daily living (ADL) could be assessed in 192 (97.5%) and was independent in 158 (80.2%), moderately impaired in 23 (11.7%), and 11 (5.6%) in completely dependent. Patients with more than three comorbidities made up 26.9% (53 patients). Thus, according to the Palumbo calculator, 43 patients were in the intermediate fitness group (21.8%), and the rest belonged to the frailty group (153, 77.7%). Overall, 79.7% of patients (157) received three-drug regimens and 20.3% (40) received two-drug regimens. In each ECOG group, more than three out of four patients received three-drug regimens. According to the ADL scale, 82.3% of the independent 65.2% of moderately impaired, and 81.8% of the dependent received three-drug regimens. Out of 53 patients with at least four comorbidities, 71.7% received three-drug regimens, and the rest received two-drug regimens. Thirty-four patients from the intermediate fit group (79.0%), and 123 (79.9%) from the frail group received three-drug regimens. Early mortality occurred in 25 patients (12.7%). No one discontinued treatment due to toxicity. To conclude, MM patients over 75 are mainly treated with triple-drug regimens, not only in reduced doses, regardless of their frailty scores. However, the absence of prospective fragility assessment did not negatively affect early mortality and the number of treatment discontinuations, which brings into question the clinical utility of current fragility scales in everyday practice.

BACKGROUND: The pain experienced by a patient during a prostate fusion biopsy is cumulative and can also be modulated by many factors. The aim of the study was to assess the association between the degree of pain intensity during prostate biopsy and the region of the biopted organ. MATERIALS AND METHODS: The study included a group of 143 patients who underwent prostate fusion biopsy under local analgesia followed by blockage of the periprostatic nerve. After a biopsy, the patients completed the original questionnaire about the pain experienced during the procedure. RESULTS: There was a statistically significant difference in pain score between cores taken in the apex (median 5 (IQR 2–5)), medium level (median 1 (IQR 1–2)), and prostate base (median 1 (IQR 1–3)) (p < 0.001). The malignancy scale ISUP ≥ 2 (p = 0.038) and lower PSA value (r = −0.17; p = 0.046) are associated with higher pain during procedure. Biopsy time was correlated with discomfort (r = 0.19; p = 0.04). Age (p = 0.65), lesion size (p = 0.29), PI-RADS score (p = 0.86), prostate volume (p = 0.22), and the number of cores (p = 0.56) did not correspond to the pain scale. CONCLUSIONS: The apex is the most sensitive sector of the prostate. ISUP ≥ 2 and patients with low PSA levels more often indicated higher values on the pain rating scale.

Introduction/Goal: Stress and negative emotions have been shown to exert a substantial impact on cancer patients, affecting their ability to adapt to therapy and the overall effectiveness. Elevated cortisol levels, a stress-induced hormone, have been shown to suppress immune system function, potentially reducing the body’s capacity to combat cancer cells. On the contrary, prolactin, a hormone that stimulates the immune system, has shown potential in this context but requires further study. The objective of this study was to investigate the acute physiological changes that occur during a single Conscious Connected Breathing (CCB) session, as part of a larger investigation on Integrative Breathwork Psychotherapy (IBP), a novel integrative psychosomatic intervention designed to improve psychosomatic and immune status in cancer patients. Methods: The project involved 93 breast cancer patients hospitalized for postoperative radiotherapy who participated in a ten-session IBP program. Fifty-six patients agreed to participate (response rate: 60%). During the experiment, 8 patients were excluded from the analysis. IBP consisted of small group sessions (up to six participants) conducted three times weekly. Each session included 45 min of CCB—defined as rhythmic circular nasal breathing at a depth exceeding resting tidal volume, without breath-holding, performed in a state of mindful acceptance—followed by 15 min of free emotional expression (verbal articulation of emerging feelings and sensations). This was a within-subject pre-post design: physiological measurements were obtained immediately before and 30 min into the tenth session (when participants had achieved technical proficiency) in all participants, who served as their own controls. Outcome measures included: arterialized capillary blood gas parameters (pH, pCO2, pO2, ctO2, COHb, HHb, cH+), serum cortisol and prolactin concentrations, and immunoglobulin A (IgA). Results: During the CCB session, blood gas analysis revealed significant changes consistent with mild respiratory alkalosis: decreases in pCO2 (p = 0.003), pO2 (p < 0.001), cH+ (p < 0.001), ctO2 (p < 0.001), COHb (p = 0.03), and HHb (p = 0.004), alongside an increase in pH (p < 0.001). Concurrently, prolactin levels increased significantly (p < 0.001), while cortisol (p < 0.001) and IgA (p < 0.001) decreased. Conclusions: This study is the first to analyze acute changes in capillary blood gas parameters and neuroendocrine balance during Conscious Connected Breathing sessions in cancer patients, revealing measurable immunostimulatory and stress-modulatory effects. The observed shift toward respiratory alkalosis, combined with increased prolactin and decreased cortisol, suggests that CCB may facilitate favorable neuroendocrine-immune interactions. These findings support the potential of breathwork as a complementary therapy for cancer patients. Further research is needed to explore underlying mechanisms and assess long-term psychological and immunological impacts.

Objective: This study aims to report the early safety outcomes from an ongoing single-center, non-randomized phase 2 trial on focal salvage stereotactic radiotherapy (s-SBRT) for local prostate cancer recurrence. Materials and methods: This prospective phase 2 study includes patients with local recurrence after conventional or hypofractionated radiotherapy, ultrahypofractionated radiotherapy, or post-prostatectomy radiotherapy. The present analysis includes an initial subset of 21 out of 55 planned patients. All patients undergo mpMRI and PSMA-PET; biopsy is not required if imaging results are unambiguous. Focal s-SBRT is delivered to the recurrent lesion with a dose of 5 × 6.75 Gy. The primary endpoint is the rate of treatment-related CTCAE v5.0 grade ≥ 3 genitourinary (GU) or gastrointestinal (GI) toxicity. Secondary endpoints include early biochemical response (BR), defined as any PSA decline at 3 months. Results: With a median follow-up of 14 months (range: 4.5–25), one patient (4.8%) experienced both early and persistent late Grade 3 GU toxicity (bladder bleeding). Late Grade 2 GU and GI toxicities occurred in five (23.8%) and one (4.8%) patients, respectively. In exploratory univariable analysis, PTV volume 13 cc was identified as a marginal predictor for increased GU/GI radiation reactions (p < 0.1). Regarding efficacy, all 21 patients (100%) demonstrated an early biochemical response, with 15 patients (71.4%) achieving a PSA reduction of 50%. Conclusions: Focal s-SBRT demonstrates a favorable early safety profile and consistent biochemical response, supporting the preliminary safety of this ongoing study.

Epilepsy is among the most prevalent neurological disorders in children, yet its diagnosis remains largely subjective and reliant on clinician expertise. This highlights the need for objective, minimally invasive biomarkers to support early diagnosis and predict drug resistance. Circulating microRNAs (miRNAs) in whole blood present a promising avenue as potential diagnostic and prognostic biomarkers for pediatric epilepsy. This study explores the relationship between selected miRNA expression levels and clinical characteristics in children with epilepsy. A literature review identified five miRNAs with high potential as biomarkers for drug-resistant epilepsy based on studies of the adult population. Quantitative RT-PCR (RT-qPCR) assays were employed to measure miRNA levels in whole blood and assess correlations with clinical characteristics. This pilot study, conducted from June to December 2023, analyzed 109 of the 115 collected blood samples. Correlation analysis revealed significant relationships between miR-142-3p, miR-194-5p, and miR-342-5p expression levels with sex, miR-142-3p and miR-342-5p expression levels with the age of seizure onset, and miR-342-5p with family history. Additionally, miR-233-3p expression showed a statistically significant correlation with EEG abnormalities. The analysis did not demonstrate the potential of the selected miRNAs as valuable biomarkers. Differences in epilepsy etiology between pediatric and adult populations, along with age and disease duration-dependent miRNA expression, suggest that adult-based findings may not be directly applicable to children. Further research in pediatric cohorts is essential to establish miRNAs as reliable biomarkers for pediatric epilepsy diagnosis and prognosis.
