Adherence to hormone therapy in patients with mCRPC: psychometric validation of the A-HT questionnaire

Abstract

The incidence rate of prostate cancer (PCa) in many Western countries is high, contributing greatly to the cancer disease bur-den. In most cases, patients progress to metastatic disease defined as castration-resistant prostate cancer after androgen deprivation (mCRPC) following primary treatment where the majority of patients receive first-line new-generation oral hormonal therapies (HT) such as Abiraterone Acetate (AA) and Enzalutamide (ENZ). Despite the importance of correct intake of these drugs, adherence in patients with mCRPC is still poorly investigated and managed with measures not specific to this population. A self-report questionnaire was developed and validated with women with breast cancer treated with oral HT (A-BET). Therefore, this study aims to test the psychometric properties of this instrument on patients with mCRPC treated with AA or ENZ. A prospective observational validation study. The questionnaire was completed by all participants and again after 7/10 days by a randomized subsample to assess stability. Sixty-six patients completed the study (mean age of 72.8 years) and 31 completed the re-test (mean age of 72.7 years). Content validity reported excellent results. Cronbach's alpha of each item showed a strong correlation. Validation of an instrument to measure adherence to HT in patients with mCRPC can be a valuable tool for health professionals involved in patient care. In addition, having a population-specific validated instrument allows to make comparisons between results from different observations.

Adherence to endocrine therapy in women with breast cancer: development and preliminary validation of the A-BET questionnaire

PURPOSE

To develop an Italian tool that measures the therapy adherence of women with breast cancer undergoing treatment with oral endocrine therapy.

METHODS

A two-phase study was conducted, which followed the guidelines of the European Statistical System for the development and validation of a questionnaire. In the first phase, the questionnaire was developed; in the second phase, a preliminary validation was carried out on patients with breast cancer undergoing treatment with oral hormonal therapies.

RESULTS

In its final version, the questionnaire presents 6 main items which aim to investigate the level of adherence, the degree of awareness of the nature of the drug taken and the reasons that may influence non-adherence. 82 patients were recruited in the validation study, with an average age of 56.4 years, while for the re-test 40 were selected with an average age of 57.3 years. Content validity reported excellent results. Cronbach's alpha of each item showed a strong degree of correlation.

CONCLUSIONS

The creation of a tool for measuring adherence to endocrine therapy in breast cancer patients can be a valuable support for healthcare professionals involved in their care. Future studies should be aimed at using A-BET (Adherence - Breast Endocrine Therapy) on larger cohorts of patients in order to verify its validity / reliability more accurately and to be able to generalize the results.

The relationship between nurse managers' leadership style and patients' perception of the quality of the care provided by nurses: Cross sectional survey

BACKGROUND

In healthcare systems, human resources play a strategic role that has a significant impact on the whole caring process. When the wellbeing of professionals is low their performance decreases, counterproductive work behaviours may became more likely, and as a result the quality of care is compromised. Studies have shown that leadership style is particularly relevant in relation to the quality of work environments in healthcare organizations.

OBJECTIVE

The main purpose of this study is to test a model that investigates the relationships between nurse managers' leadership style and patients' perception of the quality of the care provided by the nurses, through the mediation of the quality of the working environment (in terms of burnout, interpersonal strain and counterproductive work behaviour).

DESIGN

A multi-centre cross-sectional study was conducted.

SETTING

The study was conducted in five hospitals located two in the north, two in the centre and one in the south of Italy.

PARTICIPANTS

Participants were 479 registered nurses (working as staff nurses, while head nurses and nurse managers were excluded) and 829 patients aged 18 years or older, able to read and write Italian and hospitalized for at least 3 days. Severely ill or mentally disabled patients who were not able to fill in the questionnaire were excluded.

METHODS

The data were collected through two different questionnaires, one for the nurses and one for the patients. A multilevel analysis was conducted to examine the hypothesized model.

RESULTS

Results confirmed the hypothesis that, when nurses were satisfied with leadership, they felt less burned-out and strained in interpersonal relationships, they engaged less in misbehaviour, and, in turn, patients were more satisfied with the quality of the care provided by the nurses.

CONCLUSIONS

The results of this study showed that the characteristics of the organizational context, the leadership, and the behaviours of nurses, influenced patients' perceptions of nurses' care. Therefore, managers of healthcare services should take these results into account seriously in order to improve the quality of care provided to patients.

Metal Tolerance Capability of Helichrysum microphyllum Cambess. subsp. tyrrhenicum Bacch., Brullo & Giusso: A Candidate for Phytostabilization in Abandoned Mine Sites

Sardinia was known as an important mine pole in Europe during his history. Still after decades from mine closure, 75.000.000 m³ of mine waste, rich in heavy metals, were left abandoned causing a huge environmental legacy on the mine district area. Consequently, cost effective remediation is required. In this frame, phytoremediation is considered a feasible candidate. This research was focused on Helichrysum microphyllum subsp. tyrrhenicum, which is pioneer in xeric soils with low-functions, like mine tailings. The aim of this study was to evaluate its ability to extract heavy metals from mine soils and accumulate them in plant tissues and its suitability for phytostabilization. Sundry samples of soil, roots and epigean organ were collected through field sampling and analysed in order to obtain metals concentration and mineralogical characteristics. Our results indicate that this species tolerates high concentration of zinc, lead and cadmium, behaving as a species suitable for phytostabilization.

Italian version of Nursing Students' Perception of Instructor Caring (I-NSPIC): assessment of reliability and validity

BACKGROUND

Clinical experience is an essential component of nursing education since it provides students with the opportunity to construct and develop clinical competencies. Instructor caring is a pivotal facilitator at the forefront of clinical education, playing a key and complex educating role in clinical sectors. For these reasons the aims of this study was to assess the validity and reliability of the Italian version of NSPIC (I-NSPIC).

METHODS

A validation multicentre study was conducted in three different Italian universities. A total of 333 nursing students were enrolled in the 2014/2015 academic year. Exploratory factor analysis (EFA) with oblique rotation was performed to test the construct validity of I-NSPIC. The Cronbach's alpha coefficient and test retest via Intraclass Correlation Coefficient (ICC) analyses were done to assess the internal consistency and stability of the scale. A Spearman's correlation with another scale (CLES-T) was used to examine the concurrent validities.

RESULTS

Four factors (control versus flexibility, supportive learning climate, confidence through caring, appreciation of life meaning and respectful sharing) were identified in EFA. The Cronbach's alpha value showed that I-NSPIC was a reliable instrument (α = 0.94) and the ICC coefficient was satisfactory.

CONCLUSION

The I-NSPIC is a valid instrument for assessing the perception of instructor caring in Italian nursing students. It may also prove helpful in promoting the caring ability of nursing students and in increasing the caring interactions in the relationship between instructor and nursing students. The knowledge emerged from this study provide important insight in developing effective training strategies in the clinical training of undergraduate nursing students.

Propolis in the prevention of oral mucositis in breast cancer patients receiving adjuvant chemotherapy: A pilot randomised controlled trial

Chemo-induced oral mucositis (OM) is associated with significant symptoms, treatment delays and increased costs. This pilot randomised controlled trial aimed at evaluating the safety, tolerability and compliance with propolis in breast cancer patients receiving doxorubicin and cyclophosphamide, testing preliminary clinical efficacy of propolis in the prevention of OM, and prospectively evaluating the incidence of OM. Sixty patients were randomised to receive either a dry extract of propolis with 8%-12% of galangin plus mouth rinsing with sodium bicarbonate (experimental arm), or mouth rinsing with sodium bicarbonate (control arm). OM was evaluated with the NCI-CTCAE v4.0 after 5, 10, 15 and 21 days of treatment. Compliance with, tolerability of propolis and adverse events were recorded. The incidence of OM was also prospectively evaluated for 6 months. Two patients (6.7%) manifested a suspected skin reaction to propolis. No patient in the experimental arm developed OM > G1, while in the control arm OM > G1 was 16.7% (p = .02). The incidence of OM ≥ G1 at the end of cycles 2-8 was higher at the second (25%) and fifth cycles (45.8%). Propolis plus bicarbonate was safe, well tolerated and promisingly effective in the prevention of OM in patients with breast cancer.

The experiences of protective isolation in patients undergoing bone marrow or haematopoietic stem cell transplantation: systematic review and metasynthesis

Protective isolation is aimed at preventing infection in neutropenic patients, but it is implemented inconsistently across centres and is supported by recommendations with poor evidence. This review and metasynthesis explored the experiences and the psychological implications of protective isolation in patients with haematological malignancies undergoing bone marrow (BMT) or haematopoietic stem cell transplantation (HSCT). A systematic search of multiple databases for qualitative studies exploring BMT or HSCT patients' experiences of protective isolation was completed. The metasynthesis followed the meta-aggregative method from the Joanna Briggs Institute, with four procedural steps: (1) comprehensive search, (2) quality appraisal, (3) extraction of relevant findings and (4) synthesis of the identified findings. Twenty-six findings were extracted from 11 articles included in the review. The synthesising process yielded seven categories, aggregated into three synthesised findings: (1) isolation is a source of suffering, (2) isolation can lead to relating with oneself and (3) the person does not close the door to the outside world. This metasynthesis sheds light on patients' suffering from being isolated, and the possibility of overcoming this suffering thanks to relationships that patients have with themselves and with the external world. Healthcare providers should reconsider this practise in order to avoid unnecessary patient suffering.

Latent Growth Modeling of nursing care dependency of acute neurological inpatients

Longitudinal three-time point study, addressing how neurological adult patient care dependency varies from the admission time to the 3rd day of acute hospitalization. Nursing care dependency was measured with the Care Dependency Scale (CDS) and a Latent Growth Modeling approach was used to analyse the CDS trend in 124 neurosurgical and stroke inpatients. Care dependence followed a decreasing linear trend. Results can help nurse-managers planning an appropriate amount of nursing care for acute neurological patients during their initial stage of hospitalization. Further studies are needed aimed at investigating the determinants of nursing care dependence during the entire in-hospital stay.

Stakeholders in nursing education: their role and involvement

INTRODUCTION

In literature, there is evidence that all stakeholders need to be involved in the curricula building process to make sure that health professionals are "educated" to meet the stakeholders' "demands". In Italy, the involvement of stakeholders in the definition of university curricula is ratified by various regulations.

AIMS

To describe the major experiences of stakeholder involvement in nursing education, identify the main stakeholders for nursing education, and the processes in which they are involved.

METHODS

The search strategy included an electronic exploration of the relevant databases. The search terms were: Stakeholders, Curriculum, Nursing Education combined with Boolean operators. The references of the retrieved articles were hand searched for additional related studies.

RESULTS

Most of the studies identified were from the United Kingdom, Australia, and the USA. In Italy, no relevant studies were found. The most frequently identified stakeholders were: students, clinicians, educators, nurse managers. They were mainly involved during profound changes in the curricula and the implementation of new educational approaches.

DISCUSSION AND CONCLUSIONS

Stakeholders are mostly involved in countries with a private funding system for universities. Such funding systems have probably developed in the academia a greater propensity to involve stakeholders, to provide recognition of success when starting new programs, and are perceived more as marketing research. This seems contrary to the spirit of the Italian and European regulatory interventions, which instead, provide a structured commitment to consolidating and expanding the collaboration among universities, users, and the world of labor. This latter collaboration should facilitate internship activities, lifelong learning, and employability of the newly-graduated professionals.

Features and organization of Pain Centers in the Lazio Region, Italy, in 2011

BACKGROUND

Evidence on pain management highlights the importance of a multidisciplinary approach in order to achieve optimal therapeutic results. Such programs can be guaranteed by the Centers for Pain Management (CPMs), in which multidisciplinary teams are able to provide advanced and specialized activities for the assessment, diagnosis and treatment of chronic benign pain. To date, information related to healthcare supply and the organizational structure of these centers in Italy is incomplete. The aim of this paper was to provide an overview of the healthcare network of the CPMs in the Lazio region.

METHODS

A descriptive survey was conducted in all the 37 CPMs existing in the Lazio region in 2011 of which 28 participated.

RESULTS

CPMs were located either in Universities or in public or private hospital facilities. They included a clinic, a Day Hospital service, Day surgery and day-beds. CPMs were managed by anaesthesiologists who, in most instances, did not work in a multidisciplinary team. The number of other health professionals available, such as nurses, psychologists and physiotherapists, was limited. CPMs mainly provided drug therapy, Complementary Alternative Medicine (CAM) and complex interventional treatments. The median waiting time was 30 days. The clinics were not homogeneously distributed in the region with a higher concentration in Rome (56%), followed by other provinces of the Lazio region (26%) and the province of Rome (18%). Clearly, Rome was the city which offered the greatest range of healthcare services and the highest number of consultations with patients, which significantly differed from those of the other areas (χ²=19.6 p<0.01).

CONCLUSIONS

In 2011, the availability of CPMs was not equally distributed throughout the territory, and there was an over-utilization of the facilities in Rome and an under-utilization in the provincial areas. Moreover, this study showed a lack of a multi-professional approach to chronic pain management.

Application of accelerated carbonation on MSW combustion APC residues for metal immobilization and CO2 sequestration

The present study focuses on the application of an aqueous phase accelerated carbonation treatment on air pollution control (APC) residues from municipal solid waste combustion, aimed at assessing its influence on the environmental behaviour of the residue under concern, as well as the potential of the process in terms of sequestration of the CO2. APC residues are considered hazardous waste and must be treated before final disposal in order to achieve the immobilization/mobilization of critical contaminants such as heavy metals as well as mobilization of soluble salts. The treatment applied proved to be effective in reducing the mobility of Pb, Zn, Cr, Cu and Mo, the optimum final pH for the carbonated APC residues being in a range of 10-10.5, whilst a mobilization effect was noticed for Sb and no effect was assessed for chlorides. The effect of carbonation treatment on the contaminant release was further evaluated by means of a sequential extraction procedure, indicating that the distribution of contaminants on water soluble, exchangeable and carbonate fraction was modified after treatment. The CO2 sequestration potential assessed for the APC residues showed that the carbonation technology could be a technically viable option in order to reduce emissions from WtE plants.

Pressure ulcers in cancer palliative care patients

Terminally ill cancer patients are considered at high risk for pressure ulcers because of their clinical condition. However, in Italy, data about pressure ulcers and their prevalence are insufficient. This paper reports a study on pressure ulcers incidence and prevalence in a population of oncology patients cared for in an Italian palliative care service. A retrospective analysis of 414 clinical records of patients admitted over 6 months showed a prevalence of pressure ulcers of 22.9% and an incidence of 6.7%. Karnofsky Performance Scale Index scores, age and length of the stay were significantly related to the pressure sore development. These results support the need to focus attention on pressure ulcers prevention and treatment in terminally ill cancer patients, and to further define specific guidelines aimed at warranting patients' comfort and quality of life.

Senile anorexia in acute-ward and rehabilitations settings

The most common pathological change in eating behaviour among older persons is anorexia, which accounts for a large percent of undernutrition in older adults. The main research aims are to determine, in a sample of acute and rehabilitation elderly subjects, the prevalence of anorexia of aging and the causes most impacting on senile anorexia.

METHODS

four different Units cooperated to this research study. Patients were recruited from geriatric acute and rehabilitation wards in Italy. Each Research Unit, for the estimation of the prevalence of anorexia in elderly subjects evaluated all the patients aged over 65 recruited from April 2006 to June 2007. Nutritional status, depression, social, functional and cognitive status, quality of life, health status, chewing, swallowing, sensorial functions were evaluated in anorexic patients and in a sample of "normal eating" elderly subjects.

RESULTS

96 anorexic subjects were selected in acute and rehabilitation wards (66 women; 81.5 +/- 7 years; 30 men: 81.8 +/- 8 years. The prevalence of anorexia in the sample was 33.3% in women and 26.7% in men. Anorexic subjects were older and more frequently needed help for shopping and cooking. A higher (although not statistically significant) level of comorbidity was present in anorexic subjects. These subjects reported constipation and epigastrium pain more frequently. Nutritional status parameters (MNA, anthropometry, blood parameters) were significantly worst in anorexic subjects whereas CRP was higher. Chewing and swallowing efficiencies were significantly impaired and eating patterns were different for anorexic subjects with a significant reduction of protein rich foods.

CONCLUSIONS

consequences of anorexia can be extremely serious and deeply affect both patient's mobility, mortality and quality of life. Therefore, it is of utmost importance to perform a special evaluation of the nutritional risk, to constantly evaluate the nutritional status and feeding intake of older patients, to identify and treat the underlying disease when possible, to institute environmental and behavioural modifications, to organise staff better in order to produce higher quality feeding assistance during mealtimes, to plan early nutrition rehabilitation and nutritional education programs for caregivers. There is also the necessity to develop diagnostic procedures easy to perform, able to identify the pathogenesis of anorexia and, therefore, treatment strategies exactly fitting the patients' needs.

Acetate-fed aerobic granular sludge for the degradation of chlorinated phenols

In this study, the possibility to use acetate-fed aerobic granular sludge for the degradation of low chlorinated 4-mono-chlorophenol (4CP) and highly chlorinated 2,4,6-tri- chlorophenol (TCP) was investigated. A Granulated Sequencing Batch Reactor (GSBR) was used to carry out the experiments, with acetate as growth substrate. 4CP concentration in the influent ranged between 0 and 50 mg/l, while TCP concentration varied between 0 and 15 mg/l. Different operating conditions were applied in order to obtain the complete aerobic degradation of 4CP. For TCP degradation, anaerobic feeding and control of dissolved oxygen concentration in the bulk liquid were used to keep the granules core under anaerobic conditions due to diffusion limitations: the possibility to obtain TCP reductive dechlorination under aerated conditions was thus investigated. Differences in granules shape and size were observed with 4CP and TCP dosed in the influent, and the effects of such toxic compounds on acetate removal were evaluated.Aerobic granules grown on acetate as carbon source proved to be an interesting solution for the degradation of 4CP, showing good resistance to high 4CP concentrations in the influent even if unacclimated. The presence of TCP did not irreversibly inhibit biomass activity, and complete TCP degradation was achieved after acclimation.

[Risk management: relationship with the patient's relatives, who does what?]

Risk management is the systematic process of identification, evaluation and treatment of current and potential risks. In the last decades it has acquired a significant importance also in the medical field, where it aims to increase patient' safety, to reduce adverse events and costs, thus improving patients' outcomes. Gastrointestinal endoscopy is a clinical field where operative procedures are carried out; some of them may have complications, which can lead to legal cases; among such techniques endoscopic ultrasonography is acceptably safe. The aim of the article is to highlight some aspects of the risk management which are related with the patient's relatives, in the field of endoscopic ultrasonography: from the gathering of the case history to the required information for a safe discharge. Communication skills and attention given to the information process, can allow the reduction of clinical risks for patients undergoing endoscopic procedures.

Antioxidant activity of extracts from plants growing in Sardinia

The present work was carried out to study the effect of some plant methanol extracts and essential oils on lipid peroxidation in simple in vitro systems. The tested extracts were obtained from four plants, commonly known in the Mediterranean area, indigenous to Sardinia: Artemisia arborescens L., Calycotome villosa L., Daphne gnidium L. or naturalized in the island, Eucalyptus globulus Labill. The activity of the extracts was investigated during both autoxidation and iron or EDTA-mediated oxidation of linoleic acid at 37 degrees C in the absence of solvent, and compared with that of BHT, alpha-tocopherol and EDTA. During linoleic acid autoxidation all the extracts were active, showing an antioxidant activity in the order: BHT >alpha- tocopherol >Daphne gnidium (methanol extract) >Eucalyptus globulus (essential oil) >Calycotome villosa (essential oil) >Artemisia arborescens (essential oil and methanol extract) >Calycotome villosa (methanol extract). None showed any prooxidant activity. During the iron-catalysed oxidation of linoleic acid the oils were not active, while all the methanol extracts showed some efficiency in preventing the oxidation process. All the extracts were also tested on cell cultures to investigate their cytotoxic activity or their ability to inhibit the growth of some pathogenic microorganisms.

Plasminogen activator inhibitor-1 and carotid intima-media thickening in patients with newly detected primary hypertension

OBJECTIVE

To investigate the correlation between ultrasonographically evaluated intima-media thickness (IMT) of common carotid artery (CCA) and cardiovascular risk factors for subjects with newly detected, uncomplicated and untreated primary hypertension.

METHODS

The study population consisted of 200 subjects (123 men and 77 women, aged 46+/-7.5 years). Blood pressure was measured in the clinical setting and by 24 h noninvasive ambulatory monitoring. Fasting levels of blood glucose, plasma lipids and lipoproteins, fibrinogen and plasminogen activator inhibitor (PAI)-1 were measured. Ultrasound examination included measurement of far-wall intima-media complex of CCA and morphologic evaluation of occurrence of plaques in carotid and femoral bifurcations.

RESULTS

The prevalence of greater than normal IMT (mean IMT > or =0.80 mm) was 22%. Significant univariate correlations to the dichotomy between normal and greater than normal mean IMT were detected for age, smoking, level of LDL cholesterol, level of PAI-1 and total ultrasonographic score. Multivariate logistic regression analysis confirmed the associations between greater than normal mean IMT and plasma concentrations of LDL cholesterol and PAI-1 as well as total ultrasonographic score.

CONCLUSION

Greater than normal IMT of CCA was more strictly related to other cardiovascular risk factors than it was to blood pressure and was strongly associated with the occurrence of atherosclerotic plaques in carotid and femoral arteries. The role of PAI-1 in intima-media thickening that is emerging suggests that fibrinolytic balance is an important determinant of vessel-wall homeostasis in hypertensive patients.

Portohepatic gradient and portal hemodynamics in patients with cirrhosis due to hepatitis C virus infection

We evaluated the agreement between wedged hepatic vein pressure (WHVP), portal vein pressure (PVP), and its relationship with portal hemodynamics in 21 patients with HCV-related cirrhosis with esophageal varices. Direct measurements of the portohepatic gradient (HVPG) were obtained by ultrasound-guided fine needle puncture of the right hepatic and the portal veins. In five cases PVP was 6.4-10.4 mm Hg higher than WHVP. In 12 cases measurements were similar (WHVP - PVP < or = 3 mm Hg). In the remaining four cases WHVP was 3.6-9.6 mm Hg higher than PVP. WHVP and PVP agreement was not related to HVPG mean value, Child-Pugh score, or grading of esophageal varices. By contrast, the difference between WHVP and PVP was inversely related to the portal flow velocity (P = 0.053) and directly related to the portal vascular resistance (P = 0.02). Whereas the portal branches were visualized in patients with WHVP lower or similar to PVP, a predominant left portosystemic collateral flow was observed in patients with WHVP > PVP. Our data point out that, in patients with cirrhosis due to hepatitis C virus infection, discrepant HVPG values reflect true hemodynamic differences.

Efficacy of carbamazepine on cerebellar tremors in patients with superior cerebellar artery syndrome

Three patients with postural and intention cerebellar tremor caused by a cerebellar infarction in the superior cerebellar artery distribution were studied; treatment with carbamazepine resulted in marked improvement.

Treatment of cerebellar tremors with carbamazepine: a controlled trial with long-term follow-up

We studied the effects of carbamazepine (CBZ) (400 and 600 mg per day) in 10 patients with cerebellar tremors in a single-blind manner. All patients improved on a clinical rating scale and by accelerometric recording; there was no improvement with placebo. Our data suggest that CBZ may be a valuable drug in cerebellar tremors.
