Food Wastage

Background: Food losses and food waste represent an emerging problem with enormous economic, environmental, and social implications. Therefore, the reduction of food wastage is considered a promising strategy, not only to achieve food security but also to improve the food system sustainability. Food wastage is a serious issue also in North Africa region. Aims: This paper provides an overview on research dealing with food losses and waste (FLW) in North Africa (Algeria, Egypt, Libya, Mauritania, Morocco and Tunisia). Methods and Material: A systematic review was carried out in January 2018 using Scopus database. Issues addressed in the systematic review include geography of research on FLW in North Africa (i.e. countries considered or underserved), bibliometric parameters (e.g. journals, institutions) as well as thematic focus (agricultural loss, food waste). Selected records were also interrogated to see if they address the extent of FLW, the relation between food wastage and food security, economic implications of FLW, and environmental footprints of FLW. Results: The results show that research on FLW is still marginal in North Africa in general and in Libya and Mauritania in particular. Moreover, while there are some interesting pieces of research on the amount of FLW, environmental and economic impacts of FLW as well as their implications in terms of food security are largely overlooked. Conclusions: Therefore, North African researchers should pay more attention to food wastage issue. Such an endeavor should be supported by research policy in North Africa. Keywords: Agricultural losses, Environment, Food losses, Food security, Food wastage, Food waste, North Africa.

Food Losses

Globally, it is estimated that approximately a third of the food produced is lost or wasted. Reducing half of these losses would make it possible to increase the availability of food for another 1 billion people. Specifically, in Brazil, the amount of lost and wasted food, if used, would be enough to achieve food security, considering as a restriction for this security, the availability of food for purchase. In this context, the objective is to identify methodologies that measure losses and food waste in Brazil. For this, a systematic review of the subject was made. It can be observed that there are a few studies that quantify food losses and wastage in the country. The largest concentration of these studies is in the distribution and consumption stages of the food supply chain. Information is available from food lost and waste, mainly in the consumption and distribution phases. Otherwise, in the other phases of the supply chain, food loss and waste values in Brazil are still incipient or non-existent. Studies that identify these values can contribute to the generation of more accurate information on the subject, being able to raise the values referring to food loss and waste of the country.Keywords: supply chain; food secutity; sustainability; hungry.Perdas e desperdícios alimentares no Brasil: uma revisão sistemáticaRESUMOEstima-se que, globalmente, aproximadamente um terço dos alimentos produzidos sejam perdidos ou desperdiçados. No entanto, a redução de metade dessas perdas tornaria possível aumentar a disponibilidade de alimentos para mais 1 bilhão de pessoas. Especificamente, no Brasil, a quantidade de alimentos perdidos e desperdiçados, se utilizados, seria suficiente para alcançar a segurança alimentar, considerando como uma restrição para essa segurança, a disponibilidade de alimentos para compra. Nesse contexto, o objetivo é identificar metodologias que mensurem perdas e desperdício de alimentos no Brasil. Para isso, foi realizada uma revisão sistemática do assunto. Pode-se observar que existem poucos estudos que quantificam perdas e desperdícios de alimentos no país. A maior concentração desses estudos está nos estágios de distribuição e consumo da cadeia de suprimento de alimentos. As informações estão disponíveis a partir de alimentos perdidos e desperdiçados, principalmente nas fases de consumo e distribuição. Nas demais fases da cadeia de suprimentos, os valores de perda e desperdício de alimentos no Brasil ainda são incipientes ou inexistentes. Estudos que identifiquem esses valores podem contribuir para a geração de informações mais precisas sobre o assunto, podendo elevar os valores referentes à perda e desperdício de alimentos no país.Palavras-chave: cadeia de suprimentos; segurança alimentar; sustentabilidade; fome.

Food waste from the food service and hospitality industry is increasing, especially in Mezze serving restaurants, where a variety of dishes are usually served. To date, information on the factors affecting food waste generation in restaurants is scarce. This study aimed to identify the drivers and determinants of food waste generation while dining out at restaurants serving Mezze-type cuisine. According to the results from a convenience sample of 496 restaurant clientele, gender, age, and marital status did not affect food waste generation. Diners in both low and high price range restaurants waste above the grand mean compared to middle-range ones. Waste generation decreased significantly as the number of diners per table increased. However, ordering water-pipe, alcohol, or more dishes contributed significantly to food waste generation. As food waste is not the outcome of a single behavior, our study puts food waste generation drivers and determinants while dining out in perspective.

Living With Hiv

Abstract Background Women living with HIV (WLH) lack evidence-based information about reproductive options while managing pressures from family, clinicians, and communities to give up the idea of having children. As the reproduction intentions of WLH are not well understood, stigmatizing behaviors force them to hide their disease to avoid rejection by their family, partner, and social networks. Compliance with social norms, fear of stigma, and discrimination influence their experience. Current research is individual qualitative studies lacking the synthesis perspective necessary to guide intervention development. The purpose of this study was to synthesize the evidence to explain the reproductive decision-making process for WLH in developed countries. Methods A systematic review with qualitative research synthesis was conducted through searches in 10 electronic databases (CINAHL, EMBASE, MEDLINE, Scopus, Social Science Citation Index, Web of Science, Google Scholar, Cuidatge, Cuiden Enfispo, and SciELO). Studies published in journals from 1995 to 2019 with qualitative data about reproductive decision-making among WLH in developed countries were eligible for inclusion. Developed country was operationalized by membership in the OECD for comparative conditions of social wellbeing and economic stability. The CASP and JBI checklists for qualitative research were used to assess study quality and methodological integrity. Thematic analysis and qualitative meta-summary techniques were used for the synthesis. Results Twenty studies from 12 developed countries were included in the synthesis. Findings were organized into 3 meta-themes from 15 themes and 45 subthemes, including: (1) Shattered identity, (2) Barriers, inequities, and misinformation, (3) Coping, resiliency, and support. Reproductive decision-making was perceived as a complex process influenced by facilitators and barriers. The facilitators helped WLH cope with their new situation to become more resilient, while the barriers made their situation more difficult to manage. Conclusion WLH encounter reproductive decision-making with knowledge deficits and limited social support. An integrated approach to holistic care with comprehensive multidisciplinary counseling is needed to support WLH. Clinicians could benefit from professional development to learn how to be authentically present for WLH, including engaging in conversations, demonstrating compassion, and understanding situations. Evidence-based clinical practice guidelines need to be tailored for the family planning and sexual health needs of WLH.

AbstractA considerable amount of the population in more economically developed countries are functionally illiterate (i.e., low literate). Despite some years of schooling and basic reading skills, these individuals cannot properly read and write and, as a consequence have problems to understand even short texts. An often-discussed approach (Greenberg et al. 1997) assumes weak phonological processing skills coupled with untreated developmental dyslexia as possible causes of functional illiteracy. Although there is some data suggesting commonalities between low literacy and developmental dyslexia, it is still not clear, whether these reflect shared consequences (i.e., cognitive and behavioral profile) or shared causes. The present systematic review aims at exploring the similarities and differences identified in empirical studies investigating both functional illiterate and developmental dyslexic samples. Nine electronic databases were searched in order to identify all quantitative studies published in English or German. Although a broad search strategy and few limitations were applied, only 5 studies have been identified adequate from the resulting 9269 references. The results point to the lack of studies directly comparing functional illiterate with developmental dyslexic samples. Moreover, a huge variance has been identified between the studies in how they approached the concept of functional illiteracy, particularly when it came to critical categories such the applied definition, terminology, criteria for inclusion in the sample, research focus, and outcome measures. The available data highlight the need for more direct comparisons in order to understand what extent functional illiteracy and dyslexia share common characteristics.

Food waste has become a critical issue in modern society, especially in the urbanized and fast-growing cities of Asia. The increase in food waste has serious negative impacts on environmental sustainability, water and land resources, and food security, as well as climate and greenhouse gas emissions. Through a specific case study in Da Nang City, Vietnam, this paper examines the extent of food waste generation at the consumption stages, the eating habits of consumers, food waste from households and service establishments, as well as prospects for the reuse of food waste as pig feed. The results of this study indicate that per capita food waste generation in Da Nang has increased from 0.39 to 0.41kg in 2016, 0.46 in 2017, and reached 0.52kg in 2018. According to the results of our consumer survey, 20% of respondents stated that they often generate food waste, 67% stated they sometimes do, and 13% stated they rarely do. Furthermore, 66% of surveyed households stated that their food waste is collected and transported by pig farmers to be used as feed for pigs. The use of food waste as feed for pigs is a typical feature in Da Nang. The study also found that there is a high level of consumer awareness and willingness to participate in the 3Rs (reduce, reuse, recycle) program, which was being initiated by the city government. In service facilities such as resorts and hotels, daily food waste reached 100–200 kg in large facilities and 20–120 kg in small facilities. This waste was also collected for use in pig farming. However, there has been a fall in demand for pig feed in line with a decrease in the number of pig farms due to the African swine fever epidemic that occurred during the implementation of this study. This paper suggests that there is a strong need to take both consumer-oriented waste prevention and waste management measures, such as waste segregation at source and introduction of effective food waste recycling techniques, to ensure that food waste can be safely and sustainably used as a “valuable resource” rather than “wasted.”

BackgroundMycoplasma genitalium is increasingly seen as an emerging sexually transmitted pathogen, and has been likened to Chlamydia trachomatis, but its natural history is poorly understood. The objectives of this systematic review were to determine M. genitalium incidence, persistence, concordance between sexual partners and the risk of pelvic inflammatory disease (PID).MethodsWe searched Medline, EMBASE, LILACS, IndMed and African Index Medicus from 1 January 1981 until 17 March 2018. Two independent researchers screened studies for inclusion and extracted data. We examined results in forest plots, assessed heterogeneity and conducted meta-analysis where appropriate. Risk of bias was assessed for all studies.ResultsWe screened 4634 records and included 18 studies; six (4201 women) reported on incidence, five (636 women) on persistence, 10 (1346 women and men) on concordance and three (5139 women) on PID. Incidence in women in two very highly developed countries was 1.07 per 100 person-years (95% CI 0.61 to 1.53, I2 0%). Median persistence of M. genitalium was estimated from one to three months in four studies but 15 months in one study. In 10 studies measuring M. genitalium infection status in couples, 39%–50% of male or female sexual partners of infected participants also had M. genitalium detected. In prospective studies, PID incidence was higher in women with M. genitalium than those without (risk ratio 1.73, 95% CI 0.92 to 3.28, I2 0%, two studies).DiscussionIncidence of M. genitalium in very highly developed countries is similar to that for C. trachomatis, but concordance might be lower. Taken together with other evidence about age distribution and antimicrobial resistance in the two infections, M. genitalium is not the new chlamydia. Synthesised data about prevalence, incidence and persistence of M. genitalium infection are inconsistent. These findings can be used for mathematical modelling to investigate the dynamics of M. genitalium.Registration numbersCRD42015020420, CRD42015020405

True Incidence

The true incidence of endemic acute gastrointestinal illness (AGI) attributable to drinking water in Canada is unknown. Using a systematic review framework, the literature was evaluated to identify methods used to attribute AGI to drinking water. Several strategies have been suggested or applied to quantify AGI attributable to drinking water at a national level. These vary from simple point estimates, to quantitative microbial risk assessment, to Monte Carlo simulations, which rely on assumptions and epidemiological data from the literature. Using two methods proposed by researchers in the USA, this paper compares the current approaches and key assumptions. Knowledge gaps are identified to inform future waterborne disease attribution estimates. To improve future estimates, there is a need for robust epidemiological studies that quantify the health risks associated with small, private water systems, groundwater systems and the influence of distribution system intrusions on risk. Quantification of the occurrence of enteric pathogens in water supplies, particularly for groundwater, is needed. In addition, there are unanswered questions regarding the susceptibility of vulnerable sub-populations to these pathogens and the influence of extreme weather events (precipitation) on AGI-related health risks. National centralized data to quantify the proportions of the population served by different water sources, by treatment level, source water quality, and the condition of the distribution system infrastructure, are needed.
