    Abstract After four months of fighting the pandemic, the city of São Paulo, Brazil, entered a phase of relaxed social distancing measures in July 2020. Simultaneously, there was a decline in the social distancing rate and a reduction in the number of cases, fatalities, and hospital bed occupancy. To understand the pandemic dynamics in the city of São Paulo, we developed a multi-agent simulation model. Surprisingly, the counter-intuitive results of the model followed the city's reality. We argue that this phenomenon could be attributed to local bubbles of protection that emerged in the absence of contagion networks. These bubbles reduced the transmission rate of the virus, causing short and temporary reductions in the epidemic curve - but manifested as an unstable equilibrium. Our hypothesis aligns with the virus spread dynamics observed thus far, without the need for ad hoc assumptions regarding the natural thresholds of collective immunity or the heterogeneity of the population's transmission rate, which may lead to erroneous predictions. Our model was designed to be user-friendly and does not require any scientific or programming expertise to generate outcomes on virus transmission in a given location. Furthermore, as an input to start our simulation model, we developed the COVID-19 Protection Index as an alternative to the Human Development Index, which measures a given territory vulnerability to the coronavirus and includes characteristics of the health system and socioeconomic development, as well as the infrastructure of the city of São Paulo.

    Abstract Background: Ultra-processed Food (UPF) consumption can play a role in the pathogenesis and progression of asthma. The aim of this study was to evaluate the association between the consumption of UPF and asthma.
    Methods: This cross-sectional study included 1857 adults aged 23-25 years from the Ribeirão Preto-SP birth cohort (1978/1979). The exposure variable was the consumption of UPF (expressed as their percentage contribution to energy intake-% total caloric value [%TCV] and their percentage contribution to the amount of food ingested-%grams), which was assessed with a food frequency questionnaire. Asthma was the outcome and was defined based on a positive methacholine challenge test and the presence of wheezing, chest tightness, or shortness of breath over the last 12 months. Poisson regression with robust variance was used to estimate the association between these variables. Unadjusted analyses and analyses adjusted for sex, age, household income, smoking, and physical activity level were performed.
    Results: The prevalence of asthma in the sample was 13.2%. The mean total consumption of UPF was 37.9 ± 11.2% TCV (corresponding to 35.1 ± 15.1% grams). There was no association between the consumption of UPF and asthma in adults.
    Conclusion: This study provides no evidence for an association between the consumption of UPF and asthma in young adults.

    Abstract Background: Congenital heart diseases (CHD) are the most common type of birth defects, affecting millions of newborns every year; no prevalence data are available in São Paulo State, Brazil's most populous state. The objective is to identify trends in prevalence and risk factors for CHD in São Paulo State, Brazil.
    Methods: We developed a population-based study to estimate the CHD trend of prevalence in recent years, stratified by maternal age and geographical clusters, using all cases of CHD identified by the Live Births Information System (SINASC-Sistema de Informação Sobre Nascidos Vivos) from January 1, 2005, to December 31, 2018. We calculated the trends of prevalence, the regression coefficient (β), the annual percent change (APC), and 95% confidence interval using the Prais-Winsten regression model, with the Durbin-Watson test.
    Results: We found 10,594 cases of CHD among 8,536,101 live births (LB), a prevalence of 12.4/10,000 LB. There was no difference in the sex distribution; they are primarily Caucasian (60.2%), 75.2% born at term, and 74.4% weight > 2500 g, 66.9% of births were by cesarean section. São Paulo State presented an increasing CHD trend of prevalence (APC = 18.9%). The highest CHD prevalence rate was in mothers aged ≥ 35 years (22.2/10,000 LB). There were 12,271 specific congenital heart defects among 10,594 patients (1.16 CHD/patient). Atrial septal defect has the highest number of cases (3835), with a prevalence of 4.49/10,000 LB, corresponding to 31.3% of all CHD.
    Conclusion: CHD had an increasing prevalence trend in recent years, being highest in São Paulo City and ≥ 35-year mothers.

    Abstract Background: The number of liver transplantations is increasing worldwide, and Brazil ranks in the second position. It has one of the biggest public health care systems, which is responsible for the coordination and financial funding of transplantation procedures. Meeting the demands of such a large system of transplantation has become a challenge, particularly when attempting to minimize costs of scarce and expensive resources. The aim of this study was to investigate the process of donation, the retrieval of organs, and the transplantation itself using engineering methods based on logistics analyses.
    Methods: Three steps were used: study planning, data gathering, and data analysis. Researchers surveyed professionals to acquire raw information based on their observations, experience, and knowledge. Then, a data analysis was conducted, putting together all the information gathered during the previous steps. Bias was removed, and conflicting perceptions were resolved in order to have a standard view on the transplantation process.
    Results: Data was gathered between 2014 and 2018 and included 5502 liver donors and 2678 (48.7%) patients who received liver transplants organs. A total of 2824 organs were refused because of logistics issues (transport and handling). Interviews of health care professionals enabled the design of a process map in which 4 stakeholders were identified: patient, physician, organ, and information.
    Conclusions: The liver transplantation process is analyzed based on a supply chain methodology applying this knowledge and putting together medical and engineering sciences to promote better efficiency and outcomes for the transplantation program. Future studies should focus on the implementation of these ideas aiming to promote optimization gains in any step of the process.

    Abstract As whole-genome sequencing (WGS) becomes the gold standard tool for studying population genomics and medical applications, data on diverse non-European and admixed individuals are still scarce. Here, we present a high-coverage WGS dataset of 1,171 highly admixed elderly Brazilians from a census-based cohort, providing over 76 million variants, of which ~2 million are absent from large public databases. WGS enables identification of ~2,000 previously undescribed mobile element insertions without previous description, nearly 5 Mb of genomic segments absent from the human genome reference, and over 140 alleles from HLA genes absent from public resources. We reclassify and curate pathogenicity assertions for nearly four hundred variants in genes associated with dominantly-inherited Mendelian disorders and calculate the incidence for selected recessive disorders, demonstrating the clinical usefulness of the present study. Finally, we observe that whole-genome and HLA imputation could be significantly improved compared to available datasets since rare variation represents the largest proportion of input from WGS. These results demonstrate that even smaller sample sizes of underrepresented populations bring relevant data for genomic studies, especially when exploring analyses allowed only by WGS.

    Abstract Pheidole Westwood, 1839 is a hyperdiverse ant genus that is widely distributed in a variety of terrestrial ecosystems, especially in the tropics. The identification of Pheidole species is challenging, thus contributing to the description of several questionable morphospecies in the literature and making the geographic distribution of most species uncertain. In this work, we present the first records of Pheidole tijucana Borgmeier, 1927 from the state of São Paulo, Brazil. The specimens were recorded at Parque Ibirapuera Conservação, an urban green area located in the southern part of the city of São Paulo. The sampling was performed in 2015, 2016, and 2017 using pitfall traps. In total, 224 specimens (one major worker and 223 minor workers) of P. tijucana were recorded. Our new data help fill a distribution gap and highlights the importance of reporting species that are a challenge to identify.

    Abstract: ... of potential microcystin (MC) and saxitoxin (STX)-producing cyanobacteria in the Lobo reservoir, São Paulo ...

    Abstract Freshwater reservoirs constitute an important source of drinking water, but eutrophication and higher temperatures increase the risk of more frequent blooms of cyanobacteria, including species that produce toxins. To improve the prediction of cyanotoxin episodes, we studied the annual occurrence of potential microcystin (MC) and saxitoxin (STX)-producing cyanobacteria in the Lobo reservoir, São Paulo State, Brazil. Relationships among environmental variables, cyanobacterial biomass, numbers of the mcyE and sxtA genotypes (genes encoding production of MC and STX, respectively), and concentrations of MC and STX were determined to address variables applicable for monitoring and predicting the dynamics of cyanobacteria and cyanotoxins in the reservoir. Microscopy confirmed the presence of potentially toxin-producing cyanobacteria at all sampling times, and qPCR detection showed the occurrence of both mcyE and sxtA in most samples. Concentrations of MC and STX were generally low (MC 0–1.54 µg L⁻¹; STX 0.03–0.21 µg L⁻¹). The highest MC level exceeded the recommended limit for human intake of 1 µg L⁻¹. The abundance of the mcyE and sxtA genes, as well as the toxin concentrations, were positively correlated with the biomass of Phormidium and Raphidiopsis. Among environmental variables, the abundance of potential toxic cyanobacteria was mainly affected by P limitation (high TN:TP ratios). Our data show that detection of the mcyE and sxtA genotypes serves as a useful and reliable predictor of toxin episodes but might be combined with chemical toxin detection to form an environmental toolbox for cyanotoxin monitoring.

    Abstract: ... of genotypic analysis of HCV from DSS in a cohort of 80 patients from São Paulo state Brazil. HCV RNA was ...

    Abstract Hepatitis C virus (HCV) is responsible for more than 180 million infections worldwide, and about 80 % of infections are reported in Low and Middle-income countries (LMICs). Therapy is based on the administration of interferon (INF), ribavirin (RBV) or more recently Direct-Acting Antivirals (DAAs). However, amino acid substitutions associated with resistance (RAS) have been extensively described and can contribute to treatment failure, and diagnosis of RAS requires considerable infrastructure, not always locally available. Dried serum spots (DSS) sampling is an alternative specimen collection method, which embeds drops of serum onto filter paper to be transported by posting to a centralized laboratory. Here, we assessed feasibility of genotypic analysis of HCV from DSS in a cohort of 80 patients from São Paulo state Brazil. HCV RNA was detected on DSS specimens in 83 % of samples of HCV infected patients. HCV genotypes 1a, 1b, 2a, 2c and 3a were determined using the sequence of the palm domain of NS5B region, and RAS C316N/Y, Q309R and V321I were identified in HCV 1b samples. Concerning therapy outcome, 75 % of the patients who used INF +RBV as a previous protocol of treatment did not respond to DAAs, and 25 % were end-of-treatment responders. It suggests that therapy with INF plus RBV may contribute for non-response to a second therapeutic protocol with DAAs. One patient that presented RAS (V321I) was classified as non-responder, and combination of RAS C316N and Q309R does not necessarily imply in resistance to treatment in this cohort of patients. Data presented herein highlights the relevance of studying circulating variants for a better understanding of HCV variability and resistance to the therapy. Furthermore, the feasibility of carrying out genotyping and RAS phenotyping analysis by using DSS card for the potential of informing future treatment interventions could be relevant to overcome the limitations of processing samples in several location worldwide, especially in LMICs.
