To provide a comprehensive state of the art review of environmental impact assessment (EIA) of existing rapid prototyping (RP) and rapid tooling (RT), and identify prospective research needs.

The sparse literature on the EIA of RP and RT is balanced by that of the comparatively mature field of industrial ecology (IE). Hence, the review emphasizes portable IE measurement and evaluations methods. As RP and RT can also be viewed as design tools and mass customization manufacturing, other EIA may be needed.

The scarcity of research to date combined with rapid technological advances leaves a large number of unresolved issues. In addition, the special character of RP and RT, as design and manufacturing enablers implies that future research is needed.

This review is drawn from a technology in rapid evolution. Hence, unresolved issues focus on technologies that already are on the market and the research needs are formulated in terms of state of the art process research.

As technological advances multiply, so does the number of unresolved environmental problems. The review of unresolved issues points to a pressing need to assess the consequences of RP and RT while identified research needs point the way to anticipated areas where further assessment methods will be needed.

This paper intends to raise awareness about the potential environmental impacts from RP and RT, by presenting the problems associated with current methods for measuring environmental effects and discussing some of the most urgent unresolved issues, specifically with respect to materials. Indirect effects of other uses of RP and RT are discussed only briefly for lack of available data.

This quantitative phase of a mixed-methods study aims to describe the effect of the Transitional Care Bridge (TCB) programme on functional decline, mortality, health-care utilisation and health outcomes compared to usual care in a regional hospital in the Netherlands.

In a pre- and post-cohort study, patients aged ≥70 years, admitted to the hospital for ≥48 h and discharged home with an Identification of Seniors at Risk score of ≥2, were included. The TCB programme, started before discharge, encompassed six visits by the community nurse (CN). Data were obtained from the hospital registry and by three questionnaires over a three months period, addressing activities of daily living (ADL), self-rated health, self-rated quality of life and health-care utilisation.

In total, 100 patients were enrolled in this study, 50 patients in the TCB group and 50 patients in the usual care group. After three months, 36.7% was dependent on ADL in the TCB group compared to 47.1% in the usual care group. Mean number of visits by the CN in the TCB group was 3.8. Although the TCB group had a lower mortality, this study did not find any statistically significant differences in health outcomes and health-care utilisation.

Challenges in the delivery of the programme may have influenced patient outcomes. More research is needed on implementation of evidence-based programmes in smaller research settings. A qualitative phase of the study needs to address these outcomes and explore the perspectives of health professionals and patients on the delivery of the programme.

This study provides valuable information on the transitional care programme in a smaller setting.

The purpose of this paper was to study the color change kinetics of lac dye in response to aldehydes, carbon dioxide and other food spoilage metabolites for its potential application in intelligent food packaging.

UV–Vis spectroscopy was used to study the color change of dye solution. Ratio of absorbance of dye solution at 528 nm (peak of ionized form) to absorbance at 488 nm (peak of unionized form) was used to study the color change. Color change kinetics was studied in terms of change in absorbance ratio (A₅₂₈/A₄₈₈) with time using zero and first-order reaction kinetics. Lac dye-based indicator was prepared to validate the result of study for monitoring quality of strawberries.

Lac dye was orange-red in acidic medium and purple in alkaline medium. Color change of dye in response to benzaldehyde followed zero-order reaction kinetics, whereas for carbon dioxide first-order model was found best. No color change of dye solution was observed for alcohols, ketones and sulfur compounds. In the validation part, the color of the indicator label changed from purple to orange when the strawberries spoiled.

The study expands application area for lac dye as sensing reagent in intelligent food packaging for spoilage or ripeness detection of fruits and vegetables.

This paper aims to study the color change kinetics of lac dye in response to pH and food spoilage metabolites (ammonia, lactic acid and tyramine) for its potential application in intelligent food packaging.

UV-Vis spectroscopy was used to study the color change of dye solution. Ratio of absorbance of dye solution at 528 nm (peak of ionized form) to absorbance at 488 nm (peak of unionized form) was used to study the color change. Color change kinetics was studied in terms of change in absorbance ratio (A528/A488) with time using zero- and first-order reaction kinetics. An indicator was prepared by incorporating lac dye in agarose membrane to validate the result of study for monitoring quality of raw milk.

Dye was orange-red in acidic medium (pH: 2 to 5) and exhibited absorbance peak at 488 nm. It turned purple in alkaline medium (pH: 7 to10) and exhibited absorbance peak at 528 nm. The change in absorbance ratio with pH followed zero-order model. Acid dissociation constant (pKa) of dye was found to be 6.3. Color change of dye in response to ammonia and tyramine followed zero-order reaction kinetics, whereas for lactic acid, the first-order model was found best. In the validation part, the color of the indicator label changed from purple to orange-red when the milk gets spoiled.

The study opens a new application area for lac dye. The results suggest that lac dye has potential to be used as an indicator in intelligent food packaging for detection of spoilage in seafood, meat, poultry and milk.

This paper aims to evaluate the progress made in achieving sustainable development goal-2 (SDG 2) in India, with a focus on ending hunger, ensuring food security, improving nutrition and promoting sustainable agriculture. The assessment uses data from SDG Index reports, which offer a comprehensive overview of the advancements made by 28 states and 8 union territories (UTs) in India.

The evaluation is based on information derived from three editions of the SDG Index reports, initially published in 2018 and subsequently in 2019 and 2020. These reports provide a detailed analysis of the status and achievements of different states and UTs in relation to SDG 2. The categorization of states and UTs into aspirant, performer, front runner and achiever categories serves as a crucial framework for assessing the progress.

Despite concerted efforts by India, the majority of states and UTs are positioned in the aspirant and performer categories, suggesting that significant challenges persist in achieving SDG 2 targets. The results emphasize the necessity for stronger measures to elevate states and UTs to the categories of front-runners and achievers. The persistent challenges of malnutrition, hunger and their economic ramifications require immediate and strategic interventions to address these pressing concerns.

This paper contributes to the existing literature by providing a comprehensive analysis of the progress towards SDG 2 in India, using the insights from the SDG Index reports. The categorization framework used in this assessment offers a nuanced understanding of the challenges faced by different regions, highlighting the original contribution of this study. The findings underscore the urgency of targeted efforts to address malnutrition, hunger and related issues, emphasizing the importance of sustained commitment to achieving SDG 2 for the overall well-being of vulnerable populations.

This research aims to identify malnutrition risk and perception of malnourished and at-risk elderly individuals on their dietary practices.

In Phase 1, a cross-sectional study was conducted among 413 elderly individuals aged 60 years and above in agricultural settlements in Kuantan, Pahang, Malaysia. Malnutrition risk was assessed using the Mini Nutritional Assessment Short-Form (MNA-SF). In Phase 2, in-depth semi-structured interviews were conducted among 21 elderly individuals identified in Phase 1. The interviews ceased when data saturation was achieved.

25.7 per cent (n = 106) of elderly individuals were identified as malnourished and at-risk (MNA-SF score = <12). Age, smoking, income and living status were significantly associated with malnutrition risk (p < 0.05). Thematic analysis revealed four themes that represent elderly individuals’ perception on their dietary practices: the impact of aging on dietary intake; food restriction according to health condition; poor dietary intake due to feeling of loneliness; and perceived benefits of foods for health.

Strategies from multidisciplinary healthcare professionals to eliminate improper dietary practice are required for the maintenance of health, functional independence and quality of life among the elderly.

This research is at the forefront in reporting the elderly individuals’ perception on dietary practice in agricultural settlement. Attention to individual’s health issues and the associated factors that may influence their dietary practices is essential to provide appropriate interventions to achieve optimum nutritional status and healthy aging.

This systematic review (SR) aims to investigate plate waste quantity, determinant factors, and food waste costs in Indonesian hospitals.

This SR was conducted by searching for articles published on the Web of Science, PubMed, Emerald insight, ScienceDirect and hand-searching on nationally accredited journals in Indonesia which consist of 29 journals in nutrition, environment and public health. The inclusion criteria in this review were peer-reviewed articles, original research, research locations in hospitals in Indonesia and articles in English or Bahasa (Indonesian language).

There were 21 studies (17 observational studies and 4 experimental studies) included in this systematic review. Results from 17 observational studies showed that the median plate waste was 27.6% (14.8%–88.7%). High plate waste was found in this review, particularly in pediatric patients and patients who receive liquid diet orally. Staple food and vegetables have a high contribution to patients’ plate waste. Economic costs of plate waste were $0.07–$0.5 per capita per day. Determinant factors of patient’s plate waste were patient clinical conditions, food taste and environmental conditions of hospital food service. Results from four experimental studies showed that meal replacement and smaller food portion intervention could reduce significant plate waste. Nevertheless, there is no conclusive evidence for food waste reduction intervention because of small intervention studies in Indonesia.

There was a high disparity in the quantity of plate waste and economic costs between studies included in this review.

Improving food sensory and adjusting food portions particularly for staple food and vegetables can be done as a way to reduce patient’s plate waste.

This SR is the first review of Indonesian hospital plate waste.

The purpose of this paper is to systematically review and critically examine food losses and waste quantification in supply chain, especially in studies that tackle all the supply chain activities in a real context.

This work employed a systematic literature review methodology on the extant literature focusing on peer-reviewed journal articles published from 2000 to 2019.

A systematic analysis of 117 articles reveals that downstream supply chains are studied to a greater extent than upstream supply chains, with an emphasis on consumer waste. The findings also highlight more than half of the articles focus on only one supply chain activity. In terms of the methodologies, surveys and modelling methods are the most used to measure food losses and wastes, adopt monetary, carbon emission and calorific metrics. This study highlights that while food losses and waste research remains a relevant field of study, it has yet to been fully explored.

The main limit is the adoption of a systematic review method for food losses and waste quantification in supply chain.

The results suggest that supply chain managers should invest in acquiring more knowledge about food losses in the global network. Upstream supply chains should be more studied and integrated with the downstream supply chains. Using combined direct and indirect methods has the potential to deal with the contradictions of quantification, the lack of data and reduce losses over time and space.

Based on this review as the first one focusing exclusively on quantification of food losses and waste in supply chain context, the authors develop an aspiring research agenda that proposes opportunities for future research.

This study aims to examine the relationship between neutrophil to lymphocyte ratio (NLR), handgrip strength (HGS) and nutritional status in non-critically ill patients and outpatients.

A cross-sectional study was conducted on 80 geriatric patients. Nutritional status was evaluated using the Mini Nutritional Assessment Short Form, Geriatric Nutritional Risk Index, some anthropometric and biochemical parameters. NLR was calculated from the complete blood count results. Data were analyzed using SPSS 24.0.

While 38.3% of patients were malnourished or at risk of malnutrition, 61.7% had normal nutritional status. Mini Nutritional Assessment Short Form was not correlated with NLR, whereas it showed a weak positive correlation with HGS. According to the logistic regression analysis, age, HGS, hemoglobin and platelet to lymphocyte ratio were significant independent factors for predicting malnutrition or risk of malnutrition. The receiver operator characteristic curve analysis showed that the optimum HGS cut-off point for patients with malnourished or at risk of malnutrition was 13.2. In conclusion, HGS was associated with the nutritional status. NLR was not associated with nutritional status but associated with nutritional risk.

It is well known that malnutrition is a serious health problem among older adults, and it is important to assess the nutritional status of older adults because of the adverse health effects. In addition, to the best of the authors’ knowledge, this is the first study to determine the relationship between NLR, HGS and nutritional status in non-critically ill patients and outpatients.

The lack of food-based dietary guidelines for managing cancer among hospitalized patients has led to an increasing economic burden on the government and families in low- and middle-economy countries. There have been increasing medical costs due to delayed recovery, readmission and mortality. The purpose of this study is to contribute in reducing these effects by developing context-specific food-based dietary guidelines to assist health-care professionals and caregivers in planning diets for cancer patients.

For seven days, the dietary intakes of 100 cancer patients in the hospital were recorded using weighed food records. Data on the costs of commonly consumed foods during hospitalization were obtained from hospital requisition books as well as nearby markets and shops. The information gathered was used to create optimal food-based dietary guidelines for cancer patients.

Most patients did not meet the recommended food group and micronutrient intake according to their weighed food records. Sugar intake from processed foods was (51 ± 19.8 g), (13% ± 2%), and calories (2585 ± 544 g) exceeded recommendations. Optimized models generated three menus that met the World Cancer Research Fund 2018 cancer prevention recommendation at a minimum cost of 2,700 Tanzanian Shillings (TSH), 3500TSH, and 4550TSH per day. The optimal dietary pattern includes nutrient-dense foods from all food groups in recommended portions and within calorie limits.

Findings show that optimal dietary guidelines that are context-specific for managing cancer in hospitalized patients can be formulated using culturally acceptable food ingredients at minimum cost.
