Background: Dyspeptic symptoms are very common in the general population, with an estimated prevalence of 14% to 41%, and the majority of patients experience symptoms without an organic cause for them (so-called functional dyspepsia). While the pathophysiology of functional dyspepsia remains elusive, the impact of functional dyspepsia on quality of life is detrimental. The treatment involves a change in lifestyle—a healthy diet and physical activity—in combination with pharmacological treatments. However, currently, there is no standard therapy for this condition, although a nutritional approach appears to be feasible and well accepted by patients. In this context, the intake of some mineral water types might be able to play an important role. Objective: The aim of the present study was to evaluate whether the regular intake of bicarbonate natural mineral water (Aqua Carpatica from source “F2 Păltiniș”) is able to positively influence the symptomatic process of dyspepsia, promoting digestion and improving the quality of life of patients. Methods: The patients enrolled in this open-label study had diagnosis of functional dyspepsia formulated in accordance with the Rome III criteria. During the 4-week study, patients had to ingest tap water at 1.5 L/day (wash-out period: 2 weeks), and in the 2-week subsequent period, they had to ingest alkaline natural mineral water at 1.5 L/day. The primary efficacy endpoint of this study includes a statistically significant improvement (p < 0.05) in the “heartburn”, “regurgitation”, and “dyspepsia” subscales and the total Reflux Disease Questionnaire’s (RDQ) score with respect to the effects of alkaline natural mineral water. As secondary endpoints, we considered statistically significant improvements (p < 0.05) in quality-of-life scores (Psychological General Well-Being Index—Short form; PGWB-S), the patient’s self-assessment of the state of efficiency of their digestion, and their sense of post-prandial fullness, as well as the use of antacids. Results: Forty-five patients were enrolled: all were Caucasian and mostly women (25, 55.6% vs. 20 men, 44.4%), and they were aged between 25 and 75 years (50.6 ± 13.5 years; mean ± SD). The results of this preliminary study show a significant improvement in functional dyspepsia symptoms—as assessed via the RDQ—and an improvement in quality of life—as assessed using the PGWB-S score—after the intake of alkaline natural mineral water. Conclusions: This preliminary study provides clinical evidence for a recommendation of alkaline natural mineral water as a symptomatic treatment of dyspepsia.

Medical devices and technologies must undergo extensive testing and validation before being certified for public healthcare use, especially in oncology where a high research focus is on new advancements. Human 3D-tissue models can offer valuable insights into cancer behavior and treatment efficacy. This study developed a cell phantom setup using a rattail collagen-based hydrogel to facilitate reproducible investigations into ablation techniques, focusing on electroporation (EP) for lung tumor cells. The temperature rise due to the treatment is a critical aspect based on other studies that have discovered non-neglectable temperature values. A realistic physiological, biological phantom is crucial for electrode material development, non-thermal ablation control, tumor cell behavior study, and image-guided treatment simulation. The test system comprises a standardized 3D-printed setup, a cell-mimicking hydrogel model cultivated with NIH3T3 and HCC-827 cell lines. The treatment is evaluated with an AlamarBlue assay and the temperature is monitored with a sensor and a non-invasive MR-thermometry. Results showed the reliability of the selected monitoring methods and especially the temperature monitoring displayed interesting insights. The thermal effect due to EP cannot be neglected and it has to be discussed if this technique is non-thermal. The lesions in the phantom were able to show apoptotic and necrotic regions. The EP further led to a change in viability. These results suggest that the phantom can mimic the response of soft tissue and is a useful tool for studying cellular response and damage caused by EP or other treatment techniques.

Bleomycin ElectroScleroTherapy (BEST) is a new approach in the treatment of vascular malformations. After bleomycin is administered to the malformation, electric pulses are applied to the target area to enhance the effectiveness of bleomycin. The mode of action is comparable to the effect of electrochemotherapy on tumour vasculature. For the wider and safer use of BEST in the clinical treatment of low-flow vascular malformations, this Current Operating Procedure (COP) is being prepared. It is a proposal for the clinical standardisation of BEST using the Cliniporator as the electrical pulse generator with its associated electrodes. The electrical parameters considered in this protocol are those validated by the European Standard Operating Procedures for Electrochemotherapy (ESOPE) with the Cliniporator . General requirements are proposed, and, depending on the type of lesion, local skills and the availability of radiological equipment, two technical approaches of BEST are described based on ultrasound guided intervention or combined ultrasound and fluoroscopic guided intervention.

Prostate cancer (PCa) is a common cancer in men in developed countries. PCa treatment depends on the disease's stage; focal therapy provides an intermediate approach, with lower toxicity compared to radical prostatectomy, and better tumor control than active surveillance. We report the first retrospective analysis of prostate cancer patients treated with ECT at our institution. A cohort of 144 men with prostate cancer who were ineligible for or refused standard therapies were included and treated with ECT. Routine follow-up included PSA tests and MRI scans, as well as toxicity and genitourinary function evaluation by means of standard questionnaires. Local response was evaluated with MRI at 3 months after treatment, following the RECIST criteria for solid tumors. The procedure was technically successful in all patients and was well tolerated, with mild and temporary adverse events. Urinary and erectile functions were mostly preserved. A complete response was observed in 75% of evaluated patients, a partial response in 18%, stable disease in 5%, and disease progression in 2%. Short-term response was associated with TNM stage (p < 0.05), Gleason score (p = 0.0066), and pre-ECT PSA levels (p = 0.0070). During follow-up, 18 patients (13%) experienced disease progression; 1-year PFS was 88% (95% CI: 80%-97%) and was found to be significantly associated with tumor stage and pre-treatment PSA levels. ECT is a feasible, safe, and effective treatment for prostate cancer, with extremely low toxicity and side effects. Preliminary results suggest that it offers promising outcomes in terms of local disease control in early-stage tumors, but also in locally advanced cases where other treatments may not be viable.

Biomedical applications of electroporation are expanding out of the field of oncology into vaccination, treatment of arrhythmias and now in the treatment of vascular malformations. Bleomycin is a widely used sclerosing agent in the treatment of various vascular malformations. The application of electric pulses in addition to bleomycin enhances the effectiveness of the drug, as demonstrated by electrochemotherapy, which utilizes bleomycin in the treatment of tumors. The same principle is used in bleomycin electrosclerotherapy (BEST). The approach seems to be effective in the treatment of low-flow (venous and lymphatic) and, potentially, even high-flow (arteriovenous) malformations. Although there are only a few published reports to date, the surgical community is interested, and an increasing number of centers are applying BEST in the treatment of vascular malformations. Within the International Network for Sharing Practices on Electrochemotherapy (InspECT) consortium, a dedicated working group has been constituted to develop standard operating procedures for BEST and foster clinical trials. By treatment standardization and successful completion of clinical trials demonstrating the effectiveness and safety of the approach, higher quality data and better clinical outcomes may be achieved.

A lower thirst sensitivity frequently characterizes children and adolescents. The daily water intake can be frequently insufficient for the homeostasis and the integrity of their airway epithelium. Little is known about the real-life relationship between dehydration and coughing in young students with asthma. The aim was to investigate the effect of dehydration on coughing in asthmatic students aged ≤16 years. A validated questionnaire aimed to investigate their respiratory history and cough incidence was used. Urine samples were also collected for assessing osmolality. Wilcoxon test, the Pearson Chi Square and the Fisher Exact Test were used; p < 0.05 was assumed as significant. Valid data were obtained from 305 healthy and 56 asthmatic students. Mean urine osmolality was significantly higher in asthmatic than in healthy students (1012 ± 197.7 vs. 863.0 ± 223.0 mOsm/kg, respectively; p < 0.001), particularly in symptomatic asthmatic students (1025 ± 191.6 mOsm/kg, p < 0.01). Both the incidence and duration of coughing episodes were directly related to the degree of urine osmolality (both p < 0.001). Dehydration affects the prevalence and the duration of a cough in asthmatic students aged ≤16 years. Adequate daily water intake should be stimulated in these subjects in order to contain their basic cough attitude.

Electrochemotherapy (ECT) is a local nonsurgical effective tumor treatment in the hand of the clinician for the treatment of patients with liver tumors or metastases. The study aimed to test the technical feasibility and safety of intra-arterial (i.a.) bleomycin administration compared to the established intravenous (i.v.) administration in percutaneous electrochemotherapy (pECT). Furthermore, the equivalence hypothesis was tested between the 2 modalities in terms of local short-term response and progression-free survival. Forty-four patients have been recruited and treated by pECT for hepatocellular carcinoma, cholangiocarcinoma and liver metastatic lesions from cancers of different origin: 18 were treated with standard i.v., 26 with bleomycin i.a. administration. The 2 groups were similar for anagraphic and anamnestic data, as well as for most relevant disease specific characteristics. Technical success of the treatment was obtained in 95% and 100% of patients in i.v. and i.a. groups respectively. Short-term local response was similar in the 2 groups with a slightly higher complete remission (CR) rate in the i.a. group. There were 61.9% CR, 23.8% partial remission (PR), 4.8% stable disease (SD) in the i.v. group, and 80.6%, CR 12.9% PR, 3.2% PD (p = 0.3454). One-year progression free survival was 60% (C.I. 33%-88%) in the i.v. group and 67% (C.I. 42%-91%) in the i.a. group (p = 0.5849). The results of this study confirmed the safety and feasibility of super-selective i.a. bleomycin administration. Analysis of local response and progression free survival confirmed the equivalence hypothesis of the new modality compared to standard i.v. administration in the treatment of primary and secondary liver malignancies by pECT.

BackgroundChronic cough (CC) is a burdensome health problem in adult and older people, with a major impact on quality of life. Its management is often troublesome, and many guidelines have been released. Notwithstanding, a proportion of cases still do not reach a definite diagnosis and resolutive treatment. A coordinated approach between different specialists would be highly recommended, but its implementation in clinical practice suffers from the lack of shared protocols and poor awareness of the problem. The present consensus document has been implemented to address these issues.AimsTo develop evidence-based recommendations for the management of adults with CC.MethodsA 12-member expert task force of general practitioners, geriatricians, pneumologists, allergologists, otorhynolaringologists and gastroenterologists was established to develop evidence-based recommendations for the diagnostic and therapeutic approach to subjects with CC. A modified Delphi approach was used to achieve consensus, and the US Preventive Services Task Force system was used to rate the strength of recommendations and the quality of evidence.ResultsA total of 56 recommendations were proposed, covering 28 topics and concerning definitions and epidemiology, pathogenesis and etiology, diagnostic and therapeutic approach along with the consideration of specific care settings.ConclusionThese recommendations should ease the management of subjects with CC by coordinating the expertise of different specialists. By providing a convenient list of topics of interest, they might assist in identifying unmet needs and research priorities.

Background Acute cough is the most common symptom among children in primary care, but the impact of cough episodes was never investigated in Italian families. Methods A cross-sectional telephone survey was conducted on a representative sample of Italian families, randomly selected from general population; a specific and validated questionnaire was used. Results The sample (604 calls) was uniform by geographical distribution, and by children age and gender. Mean cough episode was 3.1/year, they were short lasting (only 4.7% > 2 weeks). Independent predictors of children cough episodes were parents’ active smoking habit and work ( p  < 0.05). The mean nursery/school absenteeism was mostly < 7 days, but of a 7–15-day duration in near 30% of cases. The pediatrician was contacted immediately only by 25% of parents and a second consultation (mostly a lung physician) usually occurred after 2–3 weeks of cough. Meanwhile, home/pharmacist suggested remedies were adopted in 50–70% of cases. Usual prescriptions were mucolytics (85.8%), antitussive agents (55.6%), non-steroideal anti-inflammatory drugs (33.8%), antibiotics (regularly or episodically 80%), and corticosteroids (systemic steroids in less than 50%, but via aerosol in more than 80% of cases). Moreover, pediatricians claimed to use homeopathic drugs regularly or episodically in almost 50%. The respondents’ willingness to spend out-of-pocket for an “effective remedy” against cough was of € 20 (>€ 30 in 18.4% of cases). Conclusions Parents’ actions against cough episodes were variable, depending on their beliefs, smoking habit, and occupational status. The parents’ perceived efficacy of usual prescriptions is poor, and their willingness to pay out-of-pocket for an “effective remedy” against cough is high. The interest for alternative treatments is not negligible in these circumstances.

Socio-economic, cultural and environmental factors are becoming increasingly important determinants of chronic obstructive pulmonary disease (COPD). We conducted a study to investigate socio-demographic, lifestyle and clinical factors, and to assess their role as predictors of acute events (mortality or hospitalization for respiratory causes) in a group of COPD patients. Subjects were recruited among outpatients who were undertaking respiratory function tests at the Pneumology Unit of the Sant'Orsola-Malpighi Hospital, Bologna. Patients were classified according to the GOLD Guidelines. 229 patients with COPD were included in the study, 44 with Mild, 68 Moderate, 52 Severe and 65 Very Severe COPD (GOLD stage). Significant differences among COPD stage, in terms of smoking status and fragility index, were detected. COPD stage significantly affected the values of all clinical tests (spirometry and ABG analysis). Kaplan-Meier estimates showed a significant difference between survival curves by COPD stage with lower event-free probability in very severe COPD stage. Significant risk factors for acute events were: underweight (HR = 4.08; 95% CI 1.01-16.54), having two or more comorbidities (HR = 4.71; 95% CI 2.52-8.83), belonging to moderate (HR = 3.50; 95% CI 1.01-12.18) or very severe COPD stage (HR = 8.23; 95% CI 2.35-28.85). Our findings indicate that fragility is associated with COPD stage and that comorbidities and the low body mass index are predictors of mortality or hospitalization. Besides spirometric analyses, FeNO measure and comorbidities, body mass index could also be considered in the management and monitoring of COPD patients.
