Advancement in packaging technology has played an essential role in reducing food waste and losses; however, most of this technology relies mostly on the use of plastics. Thus, there is an imminent need to think seriously about the transition towards a circular bioeconomy of innovative biobased materials with biodegradability potentials. This paper examines the driving forces behind the changes in food plastic packaging regimes and specifically seeks to understand how socio-technical configurations may influence niches to transition to a circular bioeconomy, particularly biobased biodegradable plastic materials. By employing a systematic review of the literature, we find that coordination with other back-end socio-technical systems that provide valorization of packaging waste is crucial to enable the transition. The literature indicates that one possible transition path is that the biobased biodegradable materials serve as “carriers of food waste”. The paper contributes to the discussion on the dynamics of food packaging in the transition to a bioeconomy viewed through the lenses of a socio-technical system (niche–regime–landscape), which continues to reinforce future actions, leading to better management of packaging end-of-life.

The objectives of this research were to identify the quantities and global warming, acidification and eutrophication potentials associated with household food waste in Bosnia and Herzegovina. In parallel, this study investigated perceptions related to food waste and using the quality function deployment for environment model, correlated reasons for discarding food waste and beliefs associated with food waste. Based on this study, it is estimated that around 2.8 kg of food waste is disposed of by the average household every week. Global warming, acidification and eutrophication potentials associated with household food waste are, on average, 3.49 kg CO2e/week, 2.42 g SO2e/week and 8.70 g PO4e/week, respectively. Also, Bosnian households discard over 80 different pieces of food packaging waste weekly, where plastic packaging is the most dominant packing type. The highest ranked reason for discarding food is linked to plate leftovers. In general, Bosnian citizens feel guilty when they waste food.

In this review, a historical perspective, functional and application trends of natural polymers used to the development of edible food packaging were presented and discussed. Polysaccharides and proteins, i.e., alginate; carrageenan; chitosan; starch; pea protein, were considered. These natural polymers are important materials obtained from renewable plant, algae and animal sources, as well as from agroindustrial residues. Historically, some of them have been widely used by ancient populations for food packaging until these were replaced by petroleum-based plastic materials after World War II. Nowadays, biobased materials for food packaging have attracted attention. Their use was boosted especially because of the environmental pollution caused by inappropriate disposal of plastic packaging. Biobased materials are welcome to the design of food packaging because they possess many advantages, such as biodegradability, biocompatibility and low toxicity. Depending on the formulation, certain biopolymer-based packaging may present good barrier properties, antimicrobial and antioxidant activities Thus, polysaccharides and proteins can be combined to form diverse composite films with improved mechanical and biological behaviors, making them suitable for packaging of different food products.

Abstract Peripherally inserted central venous catheters (PICCs) are known to have difficulties with catheter occlusions. This paper evaluates the scope of PICC occlusions, their prevalence and severity, and potential interventions to decrease incidence. A systematic review of the literature is performed and demonstrates three potential interventions: utilization of a dedicated PICC insertion team, implementation of a valved PICC, and nursing education of PICC care. The evidence from the literature is evaluated, and implementation of the proposed interventions is discussed.

AbstractCan a patient diagnosed with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) be infected again? This question is still unsolved. We tried to analyze local and literature cases with a positive respiratory swab after recovery. We collected data from symptomatic patients diagnosed with SARS-CoV-2 infection in the Italian Umbria Region that, after recovery, were again positive for SARS-CoV-2 in respiratory tract specimens. Samples were also assessed for infectivity in vitro. A systematic review of similar cases reported in the literature was performed. The study population was composed of 9 patients during a 4-month study period. Among the new positive samples, six were inoculated in Vero-E6 cells and showed no growth and negative molecular test in culture supernatants. All patients were positive for IgG against SARS-CoV-2 nucleoprotein and/or S protein. Conducting a review of the literature, 1350 similar cases have been found. The presumptive reactivation occurred in 34.5 days on average (standard deviation, SD, 18.7 days) after COVID-19 onset, when the 5.6% of patients presented fever and the 27.6% symptoms. The outcome was favorable in 96.7% of patients, while the 1.1% of them were still hospitalized at the time of data collection and the 2.1% died. Several hypotheses have been formulated to explain new positive respiratory samples after confirmed negativity. According to this study, the phenomenon seems to be due to the prolonged detection of SARS-CoV-2 RNA traces in respiratory samples of recovered patients. The failure of the virus to replicate in vitro suggests its inability to replicate in vivo.

Abstract BACKGROUND: Intracranial metastasis of Gastrointestinal Stromal Tumors (GIST) is rare but presents unique treatment challenges. We present a case of intracranial metastasis of GIST with a systematic review of the literature regarding this rare clinical scenario. METHODS: A systematic review of the literature was performed to identify cases of intradural GIST metastases to the brain. Additionally, a patient case of GIST is discussed. RESULTS: Out of the 18 articles included for analysis in this review and our present case, fifteen of nineteen patients were male, and mean age was 58 years old (range 15–80 years, median 60 years). The primary site of the GIST along with site of intraperitoneal metastasis was variable. There was a large predilection for brain metastasis to the cerebrum with only one to infratentorial elements. The tumors in seven of the cases involved the dura, and there was one case with metastasis to the pituitary. Eight patients died following treatment of their intracranial disease. CONCLUSIONS: Surgery remains the mainstay of intracranial metastatic GIST, however there are many reports of good responses to radiation or chemotherapy alone. More investigation is required to determine the best course of treatment for patients with this unusual sequela of GIST.

Introduction: Self-inflicted orchidectomy and auto-castration, also known as “Eshmun complex” is a rare phenomenon. The aim of our study it to present the management of a patient who performed a self orchiectomy and propose a non-systematic review of literature about self-orchiectomy. Material and method: A 27-years old male Patient with psychiatric disorder was admitted to our ward to have been cutted his scrotum with scissors and cut away his left testicle causing active bleeding from the left spermatic artery. The patient underwent emergency surgery with clamping of the spermatic cord and hemostasis of the wound. Results: After surgery the clinical condition of the patient remained good during whole hospitalization. Urgent psychiatric evaluation was performed in order to administer proper therapy for acute management. To best of our knowledge, only 11 cases of self-orchidectomy are reported in literature and all of them except 1 case, underwent surgical exploration. Conclusions: Self-orchidectomy is an extremely rare phenomenon, often associated with psychiatric disorders, compounded by the use of drugs. In our opinion, emergency surgery should be the first choice of treatment, offering diagnostic and hemostatic purpose in a single act, aimed to prevent acute and postacute complications.

Software factories seek to develop quality software in a manner comparable to the production of other industrial products, establishing improvements in their production process so as to be more competitive. Productivity, one of the competitiveness pillars, is related to the effort required to fulfill assigned tasks. However, there is no standard way of measuring productivity, making it difficult to establish policies and strategies to improve the factory. In this article, the authors perform a systematic review of the literature on factors affecting productivity of software factories, and models for measuring it. For the period 2005-2017, 74 factors and 10 models are identified. Most of the factors are related to Programming, and a few to Analysis and Design and Testing. Also, most models for measuring productivity only consider activities concerning programming.

Numerous drug interactions related to radiopharmaceuticals take place every day in hospitals many of which are not reported or detected. Information concerning this kind of reaction is not abundant, and nuclear medicine staff are usually overwhelmed by this information. To better understand this type of reaction, and to help nuclear medicine staff deal with it, a review of the literature was conducted. The results show that almost all of radiopharmaceuticals marketed around the world present drug interactions with a large variety of compounds. This suggests that a logical framework to make decisions based on reviews incorporating adverse reactions must be created. The review also showed that researchers undertaking a review of literature, or even a systematic review that incorporates drug interactions, must understand the rationale for the suggested methods and be able to implement them in their review. Additionally, a global effort should be made to report as many cases of drug interaction with radiopharmaceuticals as possible. With this, a complete picture of drug interactions with radiopharmaceuticals can be drawn.

This paper presents the results of a systematic review of literature (56 studies) related to Sustainable Development Goal 4.7. The goal of the research reported on here is to contribute to the discussion around strategies for working towards and monitoring SDG4.7 at the institutional level. Within this overarching focus, our review of the literature was designed to identify studies that have looked at both student learning and teacher education related to SDG4.7. This twin focus stems from the recognition that achieving the SDGs will be particularly difficult if policymakers are not attentive to both sides of the learning equation—that is, first, to the ways that teachers learn to teach about issues related to SDG4.7 and, then, the ways that students acquire this knowledge and are assessed. The five findings sections of this review correspond to the five areas of emphasis embedded in the language of SDG4.7, namely, education for (a) sustainable development, (b) human rights, (c) gender equality, (d) promoting of a culture of peace and non-violence, and (e) appreciation of cultural diversity. In accordance with the purpose of this review, the synthesis for each area of emphasis digs into the details of the educational interventions, monitoring and evaluation strategies, and results that are documented in the publications analyzed. Thus, this review can be useful for informing educational or pedagogical approaches related to SDG4.7, as well as for designing monitoring and evaluation tools for the SDGs.
