Introduction of special rice genotypes under upland conditions

Although widely consumed as white rice, there are special rice cultivars that contain aromas, colors and nutrients that reach special market niches, and constitute alternatives to vary the Brazilian menu and the farmer’s income. Most genotypes of special rice have nutritional characteristics superior to those of white rice, with call for better health, which is a growing concern of the general population. Based Based on these assumptions, the objective was to evaluate the productivity of special rice genotypes in rainfed cultivation conditions, in two seasons (2016/2017 and 2017/2018), in the city of Lavras/MG The treatments consisted of the following accessions: YIN LU 31, Japanese, CMG 1164, Formoso, Aromatic, IAC 400, IAC 300, IAC 600, IAC 500, BRSMG Relâmpago, BRSMG Caçula, BRSMG Caravera, SCS119 Ruby, SCS120 Onyx. After analysis of variance, the adaptability analysis and stability was performed by the Annichiaric method. The Aromatic and IAC 300 genotypes, by evaluated under rainfed conditions, showed high productivity (greater than 3,000 kg.ha-1), higher than the state average (867 kg ha-1), and low incidence of diseases in the conditions of high lands. These special rice genotypes grown in upland and compared to cultivars of rice indicated for this cultivation condition demonstrated that it is possible to produce rice from quality and develop genotypes more adaptable to rainfed conditions, which can be excellent option of cultivation to conventional rice and thus increase the diversity of the agricultural property.

AbstractThe aim of this study was to evaluate the impact of the COVID-19 pandemic lockdown on acute myocardial infarction (AMI) care, and to identify underlying stressors in the German model region for complete AMI registration. The analysis was based on data from the population-based KORA Myocardial Infarction Registry located in the region of Augsburg, Germany. All cases of AMI (n = 210) admitted to one of four hospitals in the city of Augsburg or the county of Augsburg from February 10th, 2020, to May 19, 2020, were included. Patients were divided into three groups, namely pre-lockdown, strict lockdown, and attenuated lockdown period. An additional survey was conducted asking the patients for stress and fears in the 4 weeks prior to their AMI. The AMI rate declined by 44% in the strict lockdown period; in the attenuated lockdown period the rate was 17% lower compared to the pre-lockdown period. The downward trend in AMI rates during lockdown was seen in STEMI and NSTEMI patients, and independent of sex and age. The door-to-device time decreased by 70–80% in the lockdown-periods. In the time prior to the infarction, patients felt stressed mainly due to fear of infection with Sars-CoV-2 and less because of the restrictions and consequences of the lockdown. A strict lockdown due to the Covid-19 pandemic had a marked impact on AMI care even in a non-hot-spot region with relatively few cases of COVID-19. Fear of infection with the virus is presumably the main reason for the drop in hospitalizations due to AMI.

Abstract From 2008 to 2017, the city of Abidjan, Côte d’Ivoire experienced several Aedes-borne disease epidemics which required control of the vector mosquito population based on the reduction of larval habitats and insecticidal sprays for adult mosquitoes. This study was undertaken to assess the insecticide susceptibility status of Aedes aegypti (Linnaeus) in the city of Abidjan. Immature Ae. aegypti were sampled from several larval habitats within seven communes of Abidjan and reared to adults. Three to five days old F1 emerged adults were tested for susceptibility using insecticide-impregnated papers and the synergist piperonyl butoxide (PBO) following WHO bioassay guidelines. The results showed that Ae. aegypti populations from Abidjan were resistant to 0.1% propoxur, and 1% fenitrothion, with mortality rates ranging from 0% to 54.2%. Reduced susceptibility (93.4–97.5% mortality) was observed to 0.05% deltamethrin, 0.75% permethrin, 0.05% lambda-cyhalothrin, 5% malathion, and 0.8% chlorpyrifos-methyl. This reduced susceptibility varied depending on the insecticide and the collection site. The restoration of mortality when the mosquitoes were pre-exposed to the synergist PBO suggests that increased activity of oxidases could be contributing to resistance. Three kdr mutations (V410L, V1016I, and F1534C) were present in populations tested, with low frequencies for the Leu410 (0.28) and Ile1016 (0.32) alleles and high frequencies for the Cys1534 allele (0.96). These findings will be used to inform future arbovirus vector control activities in Abidjan.

In 2020 the first record of Wolffia arrhiza was registered in Novosibirsk Region (West Siberia) in the floodplain lake. Wolffia arrhiza formed vast stands with an area of hundreds square meters and with high productivity. Besides monodominant communities, it was met as a component of the cenoses of such hydrophytes as Stratiotes aloides , Hydrocharis morsus-ranae , as well as of the helophyte communities formed by Typha latifolia and Eleocharis mamillata . According to local residents, the large stands of Wolffia was observed for some years, thus, most likely, the population winters safely at the latitude of Novosibirsk. The most likely source of Wolffia arrhiza appearance in the lake was a deliberate introduction from the aquarium. Although the probability of this plant entering to the lake from the waste water of the city septic tank of the Novosibirsk sewage waters also exists.

SARS-CoV-2 is an RNA virus, responsible for causing an acute respiratory syndrome, which became known worldwide for its rapid spread and for causing the pandemic of a new disease: COVID-19. Thus, epidemiological studies have been developed in order to determine the extent of the problems and the magnitude of the disease. The present study aimed to evaluate the seroprevalence of SARS-CoV-2 infection and its relationship with socio-demographic and clinical-epidemiological factors in the city of Chapecó, Santa Catarina, Brazil. It was a quantitative, epidemiological, observational, cross-sectional, population-based study with 2179 participants. Socio-demographic, associated behavioral, aggravating and comorbid parameters were evaluated, relating them to positivity or not in the rapid test implemented. The rapid test identified 22.2% of the diagnosed seroprevalence of COVID-19 in the municipality in question. A higher incidence of cases was observed in people living with other people, in people who had contact with positive cases, and in symptomatic patients, corroborating with current studies. The results highlight the importance of clinical-epidemiological studies for the understanding and control of COVID-19.

AbstractBackgroundAlthough the Czech Republic weathered the first wave of the COVID-19 epidemic with relatively low incidence, the second wave of the global pandemic saw it rank among countries bearing the greatest COVID-19 burden, both in Europe and on a worldwide scale. The aim of the nationwide prospective seroconversion (PROSECO) study was to investigate the dynamics of seroconversion of anti-SARS-CoV-2 IgG antibodies in the Czech population.MethodsAll clients of the second largest health insurance company in the Czech Republic were sent a written invitation to participate in this longitudinal study. The study includes the first 30,054 persons who provided a blood sample between October 2020 and March 2021. Seroprevalence was compared between calendar periods of blood sample collection, RT-PCR test results, sociodemographic factors, and other characteristics.FindingsThe data show a dramatic increase in seropositivity over time, from 28% in October/November 2020 to 43% in December 2020/January 2021 to 51% in February/March 2021. These trends were consistent with government data on cumulative viral antigenic prevalence in the population captured by PCR testing – although the seroprevalence rates established in this study were considerably higher than those listed in government data. Data pooled across the entire study period exhibited minor differences in seropositivity between sexes, age groups and body mass index categories; results were similar between test providing laboratories. Seropositivity was substantially higher among symptomatic vs. asymptomatic persons (76% vs. 34%). At least one third of all seropositive participants were asymptomatic, and 28% participants who developed antibodies against SARS-CoV-2 never underwent PCR testing.InterpretationAntibody response provides a better marker of past SARS-CoV-2 infection than PCR testing data. Our data on seroconversion confirm the rapidly increasing prevalence in the Czech population during the dramatically rising pandemic wave prior to the beginning of massive vaccination. The planned second and third assessment of the study participants (April 2021 – September 2021, October 2021 – March 2022) will provide valuable evidence on the seroprevalence changes following vaccination and persistence of antibodies resulting from natural infection and vaccination.Research in contextEvidence before this studySimilarly to most European countries, the first COVID-19 epidemic wave in the Czech Republic produced a relatively low incidence (86.9 confirmed cases per 100,000 persons over three months). At the peaks of the second wave, however, over 100 confirmed cases per 100,000 persons were diagnosed daily and the Czech Republic ranked among the countries with the greatest burden of COVID-19 in Europe and in the world. Only a few nationwide population-based studies have been published covering the second wave of the epidemic in Europe, and none of them from the Central and Eastern European region.Added value of this studyThe PROSECO study will provide key data from the heavily affected Central European region and contribute to the epidemiological and serological characteristics of the SARS-CoV-2 infection. All 30,054 study participants were recruited between October 2020 and March 2021, thus covering all three epidemic peaks (November 2020, January and March 2021) of the second COVID-19 epidemic wave. This allows us to follow the dynamics of seroconversion of anti-SARS-CoV-2 IgG antibodies in the immunologically naive and unvaccinated population during the COVID-19 pandemic. The study participants will be re-assessed in the second (April 2021 – September 2021) and third (October 2021 – March 2022) PROSECO phases to further study the post-infection/post-vaccination dynamics of seroconversion in/after a period of massive vaccination.Implications of all the available evidenceData from the first phase of the PROSECO study indicate that the percentage of the population that has been exposed to the SARS-CoV-2 may be substantially higher than estimates based on official data on cumulative viral positivity incidence as at least one third of seropositive participants were asymptomatic, and 28% of participants who developed antibodies against SARS-CoV-2 never underwent PCR testing. Regional seroprevalence data provide key information to inform, in combination with other surveillance data, public health policies and will be instrumental for the successful management of the subsequent phases of the global pandemic.The number of seropositive participants who never underwent RT-PCR testing demonstrates the importance of serological population-based studies describing the spread and exposure to the virus in the population over time.

This article aims to assess the prevalence of fatherhood in adolescence (FA) and associated factors in a community sample of 14 to 35 year-old men. Cross-sectional population-based study realized in the urban area of the city of Pelotas-RS, Brazil. The sample was selected by clusters, according to the city census. This sub-study only comprised sexually active men. Data were collected using a self-administered questionnaire in the participants’ homes. The sample was composed for 934 men. The prevalence of fatherhood in adolescence was 8% (n = 75). We verified higher prevalence of FA among those that reported paternal absence (p < 0.001), those that had lived with stepfather (p = 0.044), and among those that had sexual debut before the age of 14 (p = 0.011). Paternal absence, have lived with a stepfather, and early sexual experience are associated factors to fatherhood in adolescence.

Abstract Glioblastoma (GBM) is the most common primary malignant brain tumor of the central nervous system with a 5-year survival of < 5%. Population studies have demonstrated that among all ethnicities, non-Hispanic whites (NHW) have the worst prognosis; however, differences within the oncogenome based on ethnicity have not been assessed. We utilized the Texas Cancer Registry (TCR) for population-based analysis including 4,134 GBM patients between the years of 1995 to 2013 with 75.6% NHW and 16.5% Hispanics. In accordance with previously published findings, within the TCR we detected a 12% relative survival improvement in Hispanics compared to NHW when controlling for known survival mediators including age, resection, chemotherapy, and radiation. In order to assess for oncogenic differences, we utilized a prospectively maintained database of 257 GBM patients within the city of Houston, TX (14.9% Hispanic) and 48 GBM patients from the National Institute of Neurology and Neurosurgery in Mexico City, Mexico (100% Hispanic) to assess for oncogenomic differences attributable to ethnicity. Next generation sequencing of GBM within the Houston cohort, for 315 tumor-related genes, identified no significant differences in genomic alterations owing to ethnicity. However, when we compared the multigenerational, mixed-heritage Hispanics present in the Houston cohort to the Mexico cohort (Sanger sequencing), a significant difference was found in the frequency of IDH1and IDH2mutations (29.8 % Mexico Hispanics, 7.9% Houston Hispanics; p=0.014). In particular, the rate of IDH2mutations is significantly enriched in the Mexico population (19%) when compared to the Houston population (0%) or to previously published rates of IDH2 mutations in GBM (~3%). Ultimately, these findings highlight the need for multiethnic trial enrollment as well as the need for improved testing of IDH2 mutations in patients of distinct ethnicities. Future studies are needed to identify the mechanisms promoting the increased frequency of IDH2 mutations in Mexican Hispanics.
