In this perspective, we draw on recent scientific research on the coffee leaf rust (CLR) epidemic that severely impacted several countries across Latin America and the Caribbean over the last decade, to explore how the socioeconomic impacts from COVID-19 could lead to the reemergence of another rust epidemic. We describe how past CLR outbreaks have been linked to reduced crop care and investment in coffee farms, as evidenced in the years following the 2008 global financial crisis. We discuss relationships between CLR incidence, farmer-scale agricultural practices, and economic signals transferred through global and local effects. We contextualize how current COVID-19 impacts on labor, unemployment, stay-at-home orders, and international border policies could affect farmer investments in coffee plants and in turn create conditions favorable for future shocks. We conclude by arguing that COVID-19’s socioeconomic disruptions are likely to drive the coffee industry into another severe production crisis. While this argument illustrates the vulnerabilities that come from a globalized coffee system, it also highlights the necessity of ensuring the well-being of all. By increasing investments in coffee institutions and paying smallholders more, we can create a fairer and healthier system that is more resilient to future social-ecological shocks.

Nearly 50% of graduate students report experiencing emotional or psychological distress during their enrollment in graduate school. Levels of distress are particularly high for transgender and non-binary graduate students who experience daily discrimination and marginalization. Universities and colleges have yet to address and accommodate the needs and experiences of transgender and non-binary graduate students. Given the multitude of challenges these students may face, educational settings should not present additional barriers to educational success and well-being. In an effort to improve graduate education for transgender and non-binary students, we add to the existing scholarship on affirming work with transgender undergraduate students by addressing the unique concerns of graduate students. We utilize a social-ecological model to identify sources of discrimination in post-secondary education and to provide transgender- and non-binary-affirming recommendations at structural, interpersonal, and individual levels. For practitioners who wish to do personal work, we provide guidance for multicultural identity exploration. A table of recommendations and discussion of ways to implement our recommendations are provided.

AbstractA survey for species of the genus Trichoderma occurring as endophytes of Coffea, and as mycoparasites of coffee rusts (Hemileia), was undertaken in Africa; concentrating on Cameroon and Ethiopia. Ninety-four isolates of Trichoderma were obtained during this study: 76 as endophytes of healthy leaves, stems and berries and, 18 directly from colonized rust pustules. A phylogenetic analysis of all isolates used a combination of three genes: translation elongation factor-1α (tef1), rpb2 and cal for selected isolates. GCPSR criteria were used for the recognition of species; supported by morphological and cultural characters. The results reveal a previously unrecorded diversity of Trichoderma species endophytic in both wild and cultivated Coffea, and mycoparasitic on Hemileia rusts. Sixteen species were delimited, including four novel taxa which are described herein: T. botryosum, T. caeruloviride, T. lentissimum and T. pseudopyramidale. Two of these new species, T. botryosum and T. pseudopyramidale, constituted over 60% of the total isolations, predominantly from wild C. arabica in Ethiopian cloud forest. In sharp contrast, not a single isolate of Trichoderma was obtained using the same isolation protocol during a survey of coffee in four Brazilian states, suggesting the existence of a ‘Trichoderma void’ in the endophyte mycobiota of coffee outside of Africa. The potential use of these African Trichoderma isolates in classical biological control, either as endophytic bodyguards—to protect coffee plants from Hemileia vastatrix, the fungus causing coffee leaf rust (CLR)—or to reduce its impact through mycoparasitism, is discussed, with reference to the on-going CLR crisis in Central America.

ObjectivesThe primary objective was to estimate the positivity rate of air travellers coming to Toronto, Canada in September and October 2020, on arrival and on day 7 and day 14. The secondary objectives were to estimate the degree of risk based on country of origin and to assess knowledge and attitudes towards COVID-19 control measures and subjective well-being during the quarantine period.DesignProspective cohort of arriving international travellers.SettingToronto Pearson Airport Terminal 1, Toronto, Canada.ParticipantsParticipants of this study were passengers arriving on international flights. Inclusion criteria were those aged 18 or older who had a final destination within 100 km of the airport, spoke English or French, and provided consent. Excluded were those taking a connecting flight, had no internet access, exhibited symptoms of COVID-19 on arrival or were exempted from quarantine.Main outcome measuresPositive for SARS-CoV-2 virus on reverse transcription PCR with self-administered oral-nasal swab and general well-being using the WHO-5 Well-being Index.ResultsOf 16 361 passengers enrolled, 248 (1.5%, 95% CI 1.3% to 1.7%) tested positive. Of these, 167 (67%) were identified on arrival, 67 (27%) on day 7, and 14 (6%) on day 14. The positivity rate increased from 1% in September to 2% in October. Average well-being score declined from 19.8 (out of a maximum of 25) to 15.5 between arrival and day 7 (p<0.001).ConclusionsA single arrival test will pick up two-thirds of individuals who will become positive by day 14, with most of the rest detected on the second test on day 7. These results support strategies identified through mathematical models that a reduced quarantine combined with testing can be as effective as a 14-day quarantine.

Social Ecological Theory

Health promotion programs often lack a clearly specified theoretical foundation or are based on narrowly conceived conceptual models. For example, lifestyle modification programs typically emphasize individually focused behavior change strategies, while neglecting the environmental underpinnings of health and illness. This article compares three distinct, yet complementary, theoretical perspectives on health promotion: behavioral change, environmental enhancement, and social ecological models. Key strengths and limitations of each perspective are examined, and core principles of social ecological theory are used to derive practical guidelines for designing and evaluating community health promotion programs. Directions for future health promotion research are discussed, including studies examining the role of intermediaries (e.g., corporate decision-makers, legislators) in promoting the well-being of others, and those evaluating the duration and scope of intervention outcomes.

Studies have shown increased levels of distress during the coronavirus disease-19 (COVID-19) pandemic, and college students are becoming more recognized as a vulnerable population. This narrative systematic review aims to synthesize the current understanding of mental health, lifestyle, and socioeconomic impacts that the pandemic had on college students in the United States. A search was conducted on PubMed, PsycInfo, and Web of Science. A total of 34 observational studies were included which examined aspects of college students’ health and experiences during the COVID-19 pandemic in the United States. A great deal of students was shown to experience a moderate level of stress and subsyndromal depression and anxiety in the early months of the COVID-19 pandemic. Several risk and protective factors have been characterized. Students experienced various academic, financial, and housing disruptions. Studies have highlighted the need for institutional support to reduce the adverse psychological impact of the pandemic. There is a need for further large-scale research to assess the scope of COVID-19-related biopsychosocial impact, especially in vulnerable populations such as racial/ethnic and sexual/gender minorities.
