RESUMO
Conservation efforts have been implemented in agroecosystems to enhance pollinator diversity by creating grassland habitat, but little is known about the exposure of bees to pesticides while foraging in these grassland fields. Pesticide exposure was assessed in 24 conservation grassland fields along an agricultural gradient at two time points (July and August) using silicone band passive samplers (nonlethal) and bee tissues (lethal). Overall, 46 pesticides were detected including 9 herbicides, 19 insecticides, 17 fungicides, and a plant growth regulator. For the bands, there were more frequent/higher concentrations of herbicides in July (maximum: 1600 ng/band in July; 570 ng/band in August), while insecticides and fungicides had more frequent/higher concentrations in August (maximum: 110 and 65 ng/band in July; 1500 and 1700 ng/band in August). Pesticide concentrations in bands increased 16% with every 10% increase in cultivated crops. The bee tissues showed no difference in detection frequency, and concentrations were similar among months; maximum concentrations of herbicides, insecticides, and fungicides in July and August were 17, 27, and 180 and 19, 120, and 170 ng/g, respectively. Pesticide residues in bands and bee tissues did not always show the same patterns; of the 20 compounds observed in both media, six (primarily fungicides) showed a detection-concentration relationship between the two media. Together, the band and bee residue data can provide a more complete understanding of pesticide exposure and accumulation in conserved grasslands.

Mentorship and collaboration necessarily shaped opportunities for women in science, especially in the late nineteenth century at rapidly expanding public co-educational universities. A few male faculty made space for women to establish their own research programs and professional identities. At the University of Minnesota, botanist Conway MacMillan, an ambitious young department chair, provided a qualified mentorship to Josephine Tilden. He encouraged her research on algae and relied on her to do departmental support tasks even as he persuaded the administration to move her from instructor to assistant professor in 1903. Resulting publications on Minnesota algae led her to look further west, first at Yellowstone National Park and then along the Pacific Northwest coast. After visiting a particularly productive littoral site on Vancouver Island, she suggested that they establish a Minnesota Seaside Station there. Over its seven years in operation under the Midwestern leaders, that location proved remarkably productive. At the remote site, the two operated within their typical but not inevitable gendered roles and deliberately defined their seaside station as unconventional. They expected participants to study productively and, at the same time, find imaginative ways to enjoy nature at a place far from urban amenities. Gendered expectations remained casual as participants moved both within and against them. This study investigates how, in the early twentieth century, the role and expectations of mentorship shifted as Tilden established her own independent research agenda. The Minnesota Seaside Station, in particular, proved significant in developing the leadership skills essential for her to pursue research in the Pacific region at a time when American expansionism and indigenous cooperation made sites accessible to academic researchers.

The program designed to prevent substance use should be planned in multiple dimensions. One of these programs is Project Star. This study aims to evaluate the studies on the Project Star and identify the strengths and weaknesses of the program. For this purpose, the keywords "Project Star" and "Midwestern Prevention Project" were scanned from databases. The results of these studies were evaluated by giving a summary of the studies included in the study. As a result, the strengths of Project Star are that it is multidimensional, focuses on early development periods, includes the individual's ecological environment, and reduces substance use in later development periods, and not having an internet-based version. This situation has been identified as its weaknesses since its situation in other societies is unknown due to its cost and limited international applications.

Features of rural life, such as low population density and greater distances from urban areas, could worsen the prospects of addiction recovery for rural residents. Gossip is a central feature of rural life, and studies have shown that being the target of it can worsen health and well-being. However, no previous study has focused on the impact of gossip on addiction in rural communities. The current study employed semi-structured interviews with individuals in recovery, as well as addiction providers, to create a conceptual model of the relationship between gossip and addiction recovery in a rural region of Minnesota. The conceptual model depicted a bi-directional relationship between the individual and the community and suggested that gossip transforms from negative to positive over the course of addiction, early recovery, and long-term recovery. These data demonstrate that education at both the community and individual levels could support the transition to long-term recovery.

Crayfishes (Decapoda) are common inhabitants of agricultural headwater streams in the Midwestern USA that have been impacted by physical habitat degradation and contamination by agricultural pollutants. The frequency and severity of injuries within crayfish communities are indicators of crayfish aggression, which is influenced by physical, chemical, and biotic factors. Previous studies have not evaluated the relationships of the frequency and severity of crayfish injuries with physical habitat quality, water quality, and biotic factors within agricultural headwater streams. Understanding these relationships will assist with determining if crayfish injury variables can serve as an indicator of physical habitat quality or water quality in these small degraded streams. We sampled crayfishes, documented the frequency and type of injuries, and measured instream habitat and water chemistry in 2014 and 2015 within 12 agricultural headwater streams in Indiana, Michigan, and Ohio. We documented five native crayfish species from 1641 adult captures. The most abundant species were Faxonius rusticus, Faxonius immunis, and Faxonius propinquus. Linear mixed effect model analyses indicated that four crayfish injury response variables were positively correlated (p < 0.05) with crayfish density, physical habitat quality, and water velocity diversity and that crayfish injury response variables were more strongly correlated with crayfish density than physical habitat quality or water quality. Our results indicate that response variables describing the severity and frequency of crayfish injuries can be effective indicators of physical habitat quality in agricultural headwater streams.

BACKGROUND: The prevalence of Plasmodium falciparum and Intestinal Parasitic Infections (IPIs) - with the corresponding pathogenesis among children remain uncertain. This study aimed at determining the prevalence and the outcomes (including anaemia) of the respective infections and co-infections. Anaemia is a condition in which the number of red blood cells transporting oxygen to the various body parts is not sufficient to meet the needs of the body. METHODS: This was a cross sectional study conducted among 476-refugee camp school children. Kato-Katz technique was used to screen stool samples for intestinal parasites. Microscopy was used for malaria testing while the portable Haemoglobin (Hb) calorimeter was used to measure haemoglobin concentration. RESULTS: The overall prevalence of the mixed infections was 63.03%. Plasmodium falciparum was most prevalent of the single infections 262(55.04%) followed by Taenia spp. 14 (2.9%), Schistosoma mansoni 12(2.5%), Giardia lamblia 7 (2.9%), Trichuris trichiura 2(0.4%), Hookworm 2(0.4%) and Strongyloides stercoralis 1(0.2%). The odds of developing simple or uncomplicated malaria infection or anaemia was 14 times higher in individuals with dual co-infection with Plasmodium falciparum + Taenia sp. compared to single parasitic infection (Odds = 14.13, P = 0.019). Co-infection with Plasmodium falciparum + Taenia spp, was a strong predictor of Malaria and anaemia. CONCLUSION: This study shows that Plasmodium falciparum and Taenia spp. co-infections is a stronger predictor of malaria and anaemia. The prevalence of malaria and anaemia remains higher than the other regions in Uganda outside restricted settlements. The findings of this study underline the need for pragmatic intervention programmes to reduce burden of the co-infections in the study area and similar settlements.

Using a lens of structuration theory, this study highlights the ways that specific structures within the current community-based model of mental health care might enable and constrain individuals and families living with mental illness. Through a case study of a volunteer mental illness advocacy group, the authors employed a duality analysis on a variety of data collected from the case (i.e., interviews, organizational documents, and community health care data). Findings indicate that while group members encountered structural barriers to their organizational mission, they also used communicative agency creatively and collectively to (re)create structures within the current community-based model of mental health care. Member agency is examined in relation to perceived structural influence. Theoretical and practical applications of the findings are discussed.

Peer providers of mental health services use their personal illness and recovery narratives to help other mental health service users. Despite a substantial body of evidence supporting the effectiveness of these providers, little is known about the underlying strategies they employ in their professional practice. In this study, I used in-depth interviews with 23 peers to explore the most important practices they used in their day-to-day work with others. Results indicated that peers engaged in a reflexive process to strategically use their personal illness and recovery stories to help others re-story their life narratives. Peers also used communication strategies from motivational and cognitive-behavioral treatment approaches to engage, inspire, and mentor other service users. Findings suggest the need for research that further explores the rhetorical strategies used by peers using narrative methods. The development and testing of professional development opportunities to assist peers in maximizing their therapeutic potential are also warranted.

To meet the increasing food and biofuel demand, the Midwestern United States has become one of the most intensively human-disturbed hotspots, characterized by widespread cropland expansion and various management practices. However, the role of human activities in the carbon (C) cycling across managed landscape remains far from certain. In this study, based on state- and national census, field experiments, and model simulation, we comprehensively examined long-term carbon storage change in response to land use and cover change (LUCC) and agricultural management in the Midwest from 1850 to 2015. We also quantified estimation uncertainties related to key parameter values. Model estimation showed LUCC led to a reduction of 1.35 Pg (with a range of 1.3-1.4 Pg) in vegetation C pool of the Midwest, yet agricultural management barely affected vegetation C change. In comparison, LUCC reduced SOC by 4.5 Pg (3.1 to 6.2 Pg), while agricultural management practices increased SOC stock by 0.9 Pg. Moreover, we found 45% of the study area was characterized by continuously decreasing SOC caused by LUCC, and SOC in 13% and 31% of the area was fully and partially recovered, respectively, since 1850. Agricultural management was estimated to increase the area of full recovery and partial recovery by 8.5% and 1.1%. Our results imply that LUCC plays an essential role in regional C balance, and more importantly, sustainable land management can be beneficial for strengthening C sequestration of the agroecosystems in the Midwestern US, which may serve as an important contributor to C sinks in the US.

Previous work has reported that medication experience may affect medication-related problems, adherence, and quality of life. The purpose of this study was to explore medication experience of individuals taking psychotropic medication from the patient perspective using photovoice methodology. Nineteen participants were given a camera and were asked to photograph their medication experience. Individual and focus group sessions were held for photo reflection and discussion. Transcript data were analyzed to arrive at a model of medication experience. Specific medication experiences, including recognizing medication's benefits, occurrence of side effects, developing medication-taking routine, feeling burden from medications, and benefiting from nonmedication therapies, influenced medication acceptance, but in varying ways. Participants wanted their providers to understand their medication experience. Health care providers should consider exploring medication experience of patients with mental illness. Additional research is needed to evaluate whether exploring patients' medication experience in the clinical setting can improve patient-centered health care outcomes.

Effectively addressing wicked health problems, that is, those arising from complex multifactorial biological and socio-economic causes, requires transdisciplinary action. However, a significant body of research points toward substantial difficulties in cultivating transdisciplinary collaboration. Accordingly, this article presents the results of a study that adapts Systems Ethnography and Qualitative Modeling (SEQM) in response to wicked health problems. SEQM protocols were designed to catalyze transdisciplinary responses to national defense concerns. We adapted these protocols to address cancer-obesity comorbidity and risk coincidence. In so doing, we conducted participant-observations and interviews with a diverse range of health care providers, community health educators, and health advocacy professionals who target either cancer or obesity. We then convened a transdisciplinary conference designed to catalyze a coordinated response. The findings offer productive insights into effective ways of catalyzing transdisciplinarity in addressing wicked health problems action and demonstrate the promise of SEQM for continued use in health care contexts.

The purpose of this constructivist grounded theory article is to identify, explore, and theorize the social and psychological processes used by people with Parkinson disease. Analytic procedures generated the five-stage theory of Preserving self of people with Parkinson disease: (a) making sense of symptoms, (b) defining turning points, (c) experiencing identity dilemmas, (d) reconnecting the self, and (e) envisioning a future. Reminders of former selves and capabilities were painful; participants desperately sought normalcy. Participants developed creative methods for maintaining independence but frequently overestimated their abilities and took risks. Participants were 15 men and 10 women (ages 40-95), most of whom lived with their families. Disease status was ascertained through medication logs and two scales: Hoehn and Yahr staging and Activities of Daily Living. Data included 62 in-depth interviews, nonparticipant observation, and participant photos, videos, and related documents. Recommendations were derived from the theory to support processes of Preserving Self as interventions designed to reduce the loss of self and to enhance Preserving self. These recommendations included developing relationships, teaching expected and unexpected feelings and behaviors, and involvement with sensory integrating activities.

Despite enormous resources spent on sex education, the United States faces an epidemic of unplanned pregnancy and sexually transmitted infections among young people. Little research has examined the role sex educators play in alleviating or exacerbating this problem. In this study, we interviewed 50 sex educators employed by public schools throughout a Midwestern, U.S. state about their experiences in the sex education classroom. Twenty-two interviewees communicated feelings of conflicted identification and provided examples of the ways in which they experienced this subjectivity in the context of their employment. We find these interviews shed light on the as-yet-understudied communicative experience of conflicted identification by delineating key sources of such conflict and discursive strategies used in its negotiation. Our results suggest that those who experience conflicted identification and who have a sense of multiple or nested identifications within their overarching professional identity may be safeguarded to some extent from eventual organizational disidentification.

A key source of resiliency within HIV-affected African American communities is informal social support. Data from dyadic conversations and focus groups were used to address the following research question: What are HIV-positive African Americans' social support experiences within their informal social networks in response to HIV-related problems? Circumstances that exacerbated HIV-related problems included others' fear of contagion, reticence to be involved, judgment and rejection, and disregard for privacy Support from HIV-negative others buffered the impact of problems when others communicate interest, take the initiative to help, or make a long-term investment in their success. Support from other HIV-positive persons was helpful given the shared connection because of HIV, the opportunity to commiserate about what is mutually understood, and the fight for mutual survival Based on these findings, we offer suggestions for future research and social network interventions aimed at bolstering connections between HIV-positive peers, reducing stigma, and improving family support.

Through routine screenings for sexually transmitted infections (STIs) and HIV, medical providers are able to motivate behavior change. Although established models rely on quantitative measures, doing so requires time and ability to score each. Listening for verbal cues, however, could simplify the process of suggesting HIV screenings. Using mixed methods to identify verbal indicators for readiness to change, this article conducted two phases of study. First using quantitative means of identifying participant's knowledge of HIV, perceptions of safer sex, and readiness to change safer sex behaviors ( N = 487). Interviews were then conducted exploring the possibility of verbal markers for one's readiness to change ( n = 25). Results confirmed the use of verbal markers when discussing perceptions of risk. Identification of verbal markers, at three stages of change, provides new possibilities for medical providers' such as providing time saving and effective tools when seeking to motivate HIV and STI testing, and other safer sex behaviors.
RESUMO
Cryptococcus gattii, a species belonging to the Cryptococcus complex which occurs endemically in tropical and subtropical regions, has been reported as a causative agent of cryptococcosis in healthy individuals. We report a case of meningitis in HIV-negative patient from Cuiaba, MT, in the Midwestern region of Brazil. Cryptococcus gattii AFLP6/VGII was isolated from cerebrospinal fluid and molecular typing was performed by URA5-RFLP. The in vitro susceptibility profile was determined using the standard method according to the document M27A3, CLSI 2008. C. gattii AFLP6/VGII was shown to be susceptible to the antifungals tested. Treatment with 0.8 mg/kg of amphotericin B was initiated; however, the patient died 2 days after the onset of therapy.

Veterinary diagnostic laboratories identify and characterize influenza A viruses primarily through passive surveillance. However, additional surveillance programs are needed. To meet this need, an active surveillance program was conducted at pig farms throughout the midwestern United States. From June 2009 through December 2011, nasal swab samples were collected monthly from among 540 groups of growing pigs and tested for influenza A virus by real-time reverse transcription PCR. Of 16,170 samples, 746 were positive for influenza A virus; of these, 18.0% were subtype H1N1, 16.0% H1N2, 7.6% H3N2, and 14.5% (H1N1)pdm09. An influenza (H3N2) and (H1N1)pdm09 virus were identified simultaneously in 8 groups. This active influenza A virus surveillance program provided quality data and increased the understanding of the current situation of circulating viruses in the midwestern US pig population.

Even though previous works showed molecular evidence of hemotropic Mycoplasma spp. (hemoplasmas) in ring-tailed coatis (Nasua nasua) from Brazil, Bartonella sp. has not been reported in these mammals so far. The present study aimed to detect the above-mentioned agents in coatis' blood and associated ectoparasites, assessing the association between these infections and red blood parameters. Between March 2018 and January 2019, coati (n = 97) blood samples, Amblyomma sp. ticks (2242 individual ticks, resulting in 265 pools), and Neotrichodectes pallidus louse (n = 59) were collected in forested urban areas from midwestern Brazil. DNA extracted from coatis' blood, and ectoparasite samples were submitted to quantitative PCR (qPCR) (16S rRNA) and conventional PCR (cPCR) (16S rRNA and 23S rRNA) for hemoplasmas and qPCR (nuoG gene) and culturing (only blood) for Bartonella spp. Two different hemoplasma genotypes were detected in blood samples: 71% coatis positive for myc1 and 17% positive for myc2. While 10% of ticks were positive for hemoplasmas (myc1), no louse was positive. The estimated bacterial load of hemoplasmas showed no association with anemia indicators. All coatis were negative for Bartonella sp. in qPCR assay and culturing, albeit two Amblyomma sp. larvae pools, and 2 A. dubitatum nymph pools were positive in the qPCR. The present work showed a high occurrence of hemoplasmas, with two distinct hemoplasma genotypes, in coatis from forested urban areas in midwestern Brazil.
RESUMO
Introduction: The COVID-19 pandemic caused a pause to nearly all sporting activities in the spring of 2020, and collegiate athletes at the National Collegiate Athletic Association (NCAA)-affiliated universities whose sporting seasons were affected by the pandemic were granted an extra year of athletic eligibility. This study was conducted to determine how collegiate athletes planned to use an additional year of eligibility granted by the NCAA. Methods: The authors conducted a cross-sectional survey of 632 athletes from two universities in the Midwestern United States, between August and September 2021. The athletes completed an anonymous, nine-item survey to assess the effect of the pandemic on the athletic season, athletic eligibility, and potential change in an academic or professional career. Chi-square tests, generalized linear mixed models, and adjusted odds ratio were used for the analyses. Results: The participation rate was 74.5% (471 of 632). Nearly 63% (290 of 461) of the athletes received an additional year of eligibility because of the pandemic, with 193 (66.6%) planned to use their extra year for scholastic development. Male athletes (65.3% vs. 34.7%; χ2[1, n = 290] = 11.66, p < 0.001, Φ = 0.20), Division II athletes (59.6% vs. 40.4%; χ2[1, n = 290] = 13.93, p < 0.001, Φ = 0.22), and athletes who had not previously used redshirt (73.1% vs. 26.9%; χ2[1, n = 290] = 4.79, p = 0.029, Φ = 0.32) where more likely to use their extra year of eligibility academically. Conclusions: Our findings suggested that most of the athletes planned to use their extra year of eligibility to pursue further scholastic or professional development, highlighting the positive part of the COVID-19 pandemic. Future studies should investigate how these findings relate to athletes from universities in different geographical locations and intra-division schools.
