RESUMEN
One of the most difficult issues in the juice industry is to manufacture juices where processing processes minimise the impact on the native characteristics of the fruits. In this study, high-pressure technology was used on whole apple fruits in order to evaluate the effect on the juice production. Two varieties, cv. Limoncella and cv. Pink Lady, were considered. Preliminarily, the fruits were subjected to different pressures, and histological as well as pomological measurements were taken in order to identify the best treatment condition, which was established to be 600 MPa for 3 min. Juice samples were then characterised by measuring the colour, viscosity, total antioxidant capacity (TAC), and total phenolic content (TPC). The storage colour stability of the juices for both varieties showed not significant L* values between the untreated and pre-treated fruits. Juices obtained from pre-treated fruits had a viscosity significantly higher than that obtained from untreated ones. Interestingly, the TPC of high-pressure processing (HPP) pre-treated juice resulted in being significantly higher compared to the untreated ones. The HPP pre-treatment can be considered as a commercial application to modulate some quality standards for apple juice production.
RESUMEN
In this paper, the effects of four cooking procedures were evaluated, two occurring in atmospheric (in ventilated and steam oven) and two in subatmospheric (vacuum and sous vide cooking) conditions on pork Longissimus lumborum. The main objective of the study was to compare and evaluate the physical and chemical characteristics. Samples were cooked in four independent trials namely Oven (O), Steaming (ST), Vacuum Cooking (VC) and Sous Vide (SV). The analyses included temperature, cooking effect, percentage weight loss, texture (cutting and double compression tests), colour (superficially and inside the sample), microstructure (optical microscopy) and fibres shortening analysis. To assess cooking effects on significant nutritional constituents, the fatty acid composition and the content of B vitamins were analysed. Volatile profiles of samples were also compared using solid-phase microextraction. SV cooking resulted in the less favourable meat texture, presenting the highest hardness and chewiness. Moreover, high hardness values measured on SV samples is also related to the high weight loss. The technique of oven cooking (O) demonstrated superior results in terms of mechanical properties, which are closely associated with the cooking values. Specifically, the cook value C0 was significantly higher in the case of oven cooking compared to SV, VC, and ST. Mild temperature conditions and cooking times of the four considered cooking techniques did not induce significant variations in the fatty acid composition and volatile profile. Conversely, SV and VC allowed the highest amount of vitamin B retention in cooked meat. This work suggests that some differences emerged on the effects due to sub-atmospheric and atmospheric cooking compared to traditional ones.

Plasma Activated Water (PAW) has recently emerged as a promising non-chemical and non-thermal technology for the microbial decontamination of food. However, its use as a replacement for conventional disinfection solutions needs further investigation, as the impact of reactive species generated by PAW on nutritional food quality, toxicology, and safety is still unclear. The purpose of this study is to investigate how treatment with PAW affects the health-promoting properties of fresh-cut rocket salad (Eruca sativa). Therefore, the polyphenolic profile and antioxidant activity were evaluated by a combination of UHPLC-MS/MS and in vitro assays. Moreover, the effects of polyphenolic extracts on cell viability and oxidative status in Caco2 cells were assessed. PAW caused a slight reduction in the radical scavenging activity of the amphiphilic fraction over time but produced a positive effect on the total phenolic content, of about 70% in PAW-20, and an increase in the relative percentage (about 44-50%) of glucosinolate. Interestingly, the PAW polyphenol extract did not cause any cytotoxic effect and caused a lower imbalance in the redox status compared to an untreated sample. The obtained results support the use of PAW technology for fresh-cut vegetables to preserve their nutritional properties.

INTRODUCTION AND AIMS: The burden of treatment toxicities in breast cancer requires longitudinal assessment of patient-centered outcomes. The current study aimed to assess the feasibility of collecting general and breast cancer-specific quality of life (QoL), ongoing symptoms and unmet needs, in patients identified from a population-based cancer registry, and to assess the contribution of demographic, disease, and care-related factors. METHODS: Eligible patients were identified from the Victorian Cancer Registry (Victoria, Australia) using the ICD-10 code C50, diagnosed during 2013, 2011, and 2009. Data included age, area of residence, cancer diagnosis, date of diagnosis, treatment modality, and staging. Patients completed a number of validated tools including the EQ-5D-5L and FACT-B, symptom items, and unmet needs. RESULTS: Of 1006 eligible patients, the overall response rate was 45.6%. Survivors 1 year post-diagnosis had significantly greater problems with pain or discomfort (59.2%) and with anxiety or depression (51.3%) compared with survivors 5 years post-diagnosis (45.1% with pain or discomfort, p < 0.05, and 32.7% with anxiety or depression, p < 0.01). For the 5 years group, pain or discomfort and anxiety or depression were significantly higher than for the general population (32.2% and 21.6%, respectively). Improved quality of life was found in those who did not receive chemotherapy (coefficient = 0.2269, p = 0.0409) and those who did not have a longstanding health condition (coefficient = 0.6342, p < 0.001). Poorer quality of life was associated with those who were not certain what was happening with their breast cancer (coefficient = - 0.3674, p = 0.0094) and those whose cancer had not been treated, had been treated but was still present, or had returned after treatment (coefficient = - 0.5314, p = 0.0136). Across the total cohort, women were bothered by changes in weight (21.3%) and concerned about the effects of stress on their cancer (19.6%). Fear of cancer recurrence was commonly reported and did not diminish over time (60.7%, 52.2%, and 56.9% at 1, 3, and 5 years, respectively). CONCLUSION: Collecting patient-reported outcomes from a population-based sample of breast cancer survivors was feasible. Physical symptoms and psychosocial issues are common and are persistent. Use of chemotherapy was the only treatment modality that significantly impacted on QoL.

PURPOSE: There is a lack of population-based data describing patient reported outcomes (PROs) in melanoma survivors which could guide the development of interventions and resources. This study assessed overall quality of life (QoL), self-reported symptoms and unmet information needs in melanoma survivors 1, 3 or 5 years post-diagnosis. METHODS: A cross-sectional postal survey was conducted in Victoria, Australia, with eligible melanoma survivors identified from a population-based cancer registry. Patient-reported outcome measures included the EuroQoL 5-Dimension 5-Level (EQ-5D-5L), and self-reported symptoms, difficulties and information needs. Associations between demographic, disease and care-related factors and QoL were also assessed. RESULTS: A total of 476 melanoma survivors participated in the study (response rate 46.5%). Anxiety and depressive symptoms were more prevalent in survivors compared to the general population (30.7% vs 21.6%; p < 0.01). Fear of cancer recurrence (48.3%) and fear of cancer spreading (37.8%) were the most commonly reported symptom items, and approximately one in five melanoma survivors had unmet information needs related to psychological aspects of living with melanoma. Recurrent melanoma, living in a nursing home, chronic comorbidities, and melanoma diagnosed at > 2 mm thickness were associated with lower QoL. CONCLUSION: A large proportion of melanoma survivors reported ongoing quality of life deficits, fear of cancer recurrence, as well as unmet information needs up to 5 years after diagnosis. Patients may benefit from tailored informational resources and interventions that address the psychological aspects of living with and beyond melanoma.

PURPOSE: There is a lack of robust population-based data regarding the lived experience of cancer survivors. This study assessed the quality of life (QoL) of survivors of breast, colorectal, or prostate cancer, non-Hodgkin lymphoma or melanoma 1, 3 and 5 years post-diagnosis. Associations between various demographic and disease-related factors and QoL were assessed. METHODS: A cross-sectional postal survey was undertaken. Eligible participants were identified from a population-based cancer registry. Patient-reported outcomes including QoL, symptom issues and information needs were collected using validated questionnaires. RESULTS: Difficulties with all QoL domains were more prevalent amongst cancer survivors compared with the general population, particularly difficulties with usual activities (28 vs 15%) and anxiety or depression (35 vs 22%). Symptoms such as trouble sleeping, always feeling tired, trouble concentrating and fear of cancer recurrence persisted up to 5 years post-diagnosis. Factors associated with reduced QoL included having another long-standing health condition, cancer not responding fully to treatment, not having or not being certain of having a written care plan and being female. CONCLUSIONS: Cancer survivors experience inferior QoL and cancer-related symptoms for years following diagnosis. These results support further investigation into factors that contribute to poorer survivor outcomes and enhanced identification and intervention strategies for those requiring additional support.

OBJECTIVE: To assess variations in the number of general practitioner visits preceding a cancer diagnosis, and in the length of the interval between the patient first suspecting a problem and their seeing a hospital specialist. DESIGN, SETTING AND PARTICIPANTS: Analysis of data provided to the Cancer Patient Experience Survey (CPES; survey response rate, 37.7%) by 1552 patients with one of 19 cancer types and treated in one of five Victorian Comprehensive Cancer Centre hospitals, 1 October 2012 - 30 April 2013. MAIN OUTCOME MEASURES: The primary outcome was the proportion of patients who had had three or more GP consultations about cancer-related health problems before being referred to hospital. The secondary outcome was the interval between the patient first suspecting a problem and their seeing a hospital specialist. RESULTS: 34% of the patients included in the final analyses (426 of 1248) had visited a GP at least three times before referral to a hospital doctor. The odds ratios (reference: rectal cancer; adjusted for age, sex, language spoken at home, and socio-economic disadvantage index score) varied according to cancer type, being highest for pancreatic cancer (3.2; 95% CI, 1.02-9.9), thyroid cancer (2.5; 95% CI, 0.9-6.6), vulval cancer (2.5; 95% CI, 0.7-8.7) and multiple myeloma (2.4; 95% CI, 1.1-5.5), and lowest for patients with breast cancer (0.4; 95% CI, 0.2-0.8), cervical cancer (0.5; 95% CI, 0.1-2.1), endometrial cancer (0.5; 95% CI, 0.2-1.4) or melanoma (0.7; 95% CI, 0.3-1.5). Cancer type also affected the duration of the interval from symptom onset to seeing a hospital doctor; it took at least 3 months for more than one-third of patients with prostate or colon cancer to see a hospital doctor. CONCLUSION: Certain cancer types were more frequently associated with multiple GP visits, suggesting they are more challenging to recognise early. In Victoria, longer intervals from the first symptoms to seeing a hospital doctor for colon or prostate cancer may reflect poorer community symptom awareness, later GP referral, or limited access to gastroenterology and urology services.

OBJECTIVES: To examine changes in health and lifestyle indicators over 6 months in persons with type 2 diabetes mellitus receiving nutrition counseling from a registered dietitian, and to promote dietetics professionals' participation in outcomes monitoring and research. DESIGN: Prospective, noncontrolled descriptive study. SUBJECTS: Two hundred forty-four physician-referred adults with type 2 diabetes mellitus from 31 sites who received usual and customary nutrition counseling, and 83 registered dietitians. MAIN OUTCOME MEASURES: Glycemic control, coronary heart disease risk, self-management behaviors, and quality of life were measured at baseline, 3 months, and 6 months. Dietitians' perceptions of the study were also measured. STATISTICAL ANALYSIS: Repeated-measures analysis of variance, paired t test, Wilcoxon signed rank test, sign test, Spearman correlation, and chi 2 analysis were conducted. RESULTS: Weight and glycemic control, coronary heart disease risk, and self-management behaviors improved significantly between baseline and 3 months and baseline and 6 months. Weight, body mass index, and glycosylated hemoglobin value also improved significantly between 3 months and 6 months. Increased time and/or number of sessions with the registered dietitian were associated with weight loss and reduced glycosylated hemoglobin, fasting plasma glucose, total cholesterol, and triglyceride levels. Self-perceived health status and missed workdays were significantly improved at 6 months. Difficulty obtaining current laboratory values, lack of time, and inability to reach subjects for follow-up presented the greatest obstacles for the dietitians. CONCLUSIONS: Positive outcomes were observed in adults receiving nutrition intervention for type 2 diabetes. Clinical improvements were greatest between baseline and 3 months, with stabilization between 3 months and 6 months, suggesting ongoing intervention is needed to support continued clinical progress. Dietitians found participation in this state affiliate-coordinated research project rewarding.

The provision of quality food and nutrition services is at the core of dietetic practice. It is exciting to have the profession engaged in discussions regarding the development of a standardized care process/model to further enhance the quality of nutrition services. Educators, consultants, and practitioners have already spoken on behalf of such a tool. This article demonstrates how a systematic model, when incorporated into education and practice contributes to improved provision of MNT and adds value to the unique contributions of dietetic professionals. The authors hope that the discussion will continue and that more ideas and suggestions will be forthcoming.
