RESUMO

Late Pleistocene ice-age climates are routinely characterized as having imposed moisture stress on low- to mid-latitude ecosystems1-5. This idea is largely based on fossil pollen evidence for widespread, low-biomass glacial vegetation, interpreted as indicating climatic dryness6. However, woody plant growth is inhibited under low atmospheric CO2 (refs. 7,8), so understanding glacial environments requires the development of new palaeoclimate indicators that are independent of vegetation9. Here we show that, contrary to expectations, during the past 350 kyr, peaks in southern Australian climatic moisture availability were largely confined to glacial periods, including the Last Glacial Maximum, whereas warm interglacials were relatively dry. By measuring the timing of speleothem growth in the Southern Hemisphere subtropics, which today has a predominantly negative annual moisture balance, we developed a record of climatic moisture availability that is independent of vegetation and extends through multiple glacial-interglacial cycles. Our results demonstrate that a cool-moist response is consistent across the austral subtropics and, in part, may result from reduced evaporation under cool glacial temperatures. Insofar as cold glacial environments in the Southern Hemisphere subtropics have been portrayed as uniformly arid3,10,11, our findings suggest that their characterization as evolutionary or physiological obstacles to movement and expansion of animal, plant and, potentially, human populations10 should be reconsidered.

RESUMO

Extreme climate events are related to women's exposure to different forms of violence. We examined the relationship between droughts and physical, sexual, and emotional intimate partner violence (IPV) in India by using 2 different definitions of drought: precipitation-based drought and socioeconomic drought. We analyzed data from 2 rounds of a nationally representative survey, the National Family Health Survey, where married women were asked about their experiences of IPV in the previous year (2015-2016 and 2019-2021; n = 122,696). Precipitation-based drought was estimated using remote sensing data and geographic information system (GIS) mapping, while socioeconomic drought status was collected from government records. Logistic regression models showed precipitation-based drought to increase the risk of experiencing physical IPV and emotional IPV. Similar findings were observed for socioeconomic drought; women residing in areas classified as drought-impacted by the government were more likely to report physical IPV, sexual IPV, and emotional IPV. These findings support the growing body of evidence regarding the relationship between climate change and women's vulnerability, and highlight the need for gender responsive strategies for disaster management and preparedness.

RESUMO

BACKGROUND: After implementation of the Acuity Circles (AC) allocation policy, use of DCD liver grafts has increased in the United States. METHODS: We evaluated the impact of AC on rates of DCD-liver transplants (LT), their outcomes, and medical costs in a single practice. Adult LT patients were classified into three eras: Era 1 (pre-AC, 1/01/2015-12/31/2017); Era 2 (late pre-AC era, 1/01/2018-02/03/2020); and Era 3 (AC era, 05/10/2020-09/30/2021). RESULTS: A total of 520 eligible LTs were performed; 87 were DCD, and 433 were DBD. With each successive era, the proportion of DCD increased (Era 1: 11%; Era 2: 20%; Era 3: 24%; p < .001). DCD recipients had longer ICU stays, higher re-admission/re-operation rates, and higher incidence of ischemic cholangiopathy compared to those with DBD. Direct, surgical, and ICU costs during first admission were higher with DCD than DBD (+8.0%, p < .001; +4.2%, p < .001; and +33.3%, p = .001). DCD-related costs increased after Era 1 (Direct: +4.9% [Era 2 vs. 1] and +12.4% [Era 3 vs. 1], p = .04; Surgical: +17.7% and +21.7%, p < .001). In the AC era, there was a significantly higher proportion of donors ≥50 years, and more national organ sharing. Compared to DCD from donors <50 years, DCD from donors ≥50 years was associated with significantly higher total direct, surgical, and ICU costs (+12.6%, p = .01; +9.5%, p = .01; +84.6%, p = .03). CONCLUSIONS: The proportion of DCD-LT, especially from older donors, has increased after the implementation of AC policies. These changes are likely to be associated with higher costs in the AC era.

RESUMO

INTRODUCTION: Non-consented care, a form of obstetric violence involving the lack of informed consent for procedures, is a common but little-understood phenomenon in the global public health arena. The aim of this secondary analysis was to measure the prevalence and assess change over time of non-consented care during childbirth in Mexico in 2016 and 2021, as well as to examine the association of sociodemographic, pregnancy-, and childbirth-factors with this type of violence. METHODS: We measured the prevalence of non-consented care and three of its variations, forced sterilization or contraception, forced cesarean section, and forced consent on paperwork, during childbirth in Mexico for 2016 (N = 24,036) and 2021 (N = 19,322) using data from Mexico's cross-sectional National Survey on the Dynamics of Household Relationships (ENDIREH). Weighted data were stratified by geographical regions. We performed adjusted logistic regression analyses to explore associations. RESULTS: The national prevalence of non-consented care and one of its variations, pressure to get a contraceptive method, increased from 2016 to 2021. A decrease in the prevalence was observed for forced contraception or sterilization without knowledge, forcing women to sign paperwork, and non-consented cesarean sections nationally and in most regions. Women between the ages of 26 and 35 years, married, cohabiting with partner, living in urban settings, who do not identify as Indigenous, and who received prenatal services or gave birth at the Mexican Institute of Social Security (IMSS) facilities experienced a higher prevalence of non-consented care. Being 26 years of age and older, living in a rural setting, experiencing stillbirths in the last five years, having a vaginal delivery, receiving prenatal services at IMSS, or delivering at a private facility were significantly associated with higher odds of reporting non-consented care. CONCLUSION: While a decrease in most of the variations of non-consented care was found, the overall prevalence of non-consented care and, in one of its variations, pressure to get contraceptives, increased at a national and regional level. Our findings suggest the need to enforce current laws and strengthen health systems, paying special attention to the geographical regions and populations that have experienced higher reported cases of this structural problem.

RESUMO

Economic vulnerability is often reported to underlie involvement in sex work among female sex workers (FSW), but may also create urgency in women's work, limiting women's negotiating power with clients and in turn, increasing their vulnerability for violence and HIV. This study assessed economic vulnerability in relation to violence and sexual risk behaviors for HIV among a sample of FSW in Tijuana, Mexico. FSW at least 18 years of age were recruited through venue-based sampling for a survey (n = 228) and in-depth interviews (n = 50) to investigate HIV risk factors in this region. Using crude and adjusted logistic regression models, we assessed lack of financial support from others as well as reports of financial hardship separately in relation to experiencing sexual violence (e.g. by clients, police, relationship partners, in the past 6 months), physical violence (past 6 months), STI diagnosis, and inconsistent condom use (past 30 days). Qualitative interviews (n = 50), conducted with a subsample of the survey participants, were also examined for related themes. FSW who reported no financial support were more likely to report sexual violence (OR = 2.1; 95% CI:1.1-4.2). FSW who reported financial hardship were more likely to experience sexual violence (OR = 1.9; 95% CI:1.1-3.6) and physical violence (OR = 1.9; 95% CI:1.1-3.6), as well as to report past 30-day inconsistent condom use (OR = 2.4; 95%CI: 1.3-4.6) and to test positive for an STI (OR = 1.9; 95% CI:1.1-3.4). Qualitative data substantiated these findings. Findings suggest that interventions to improve economic well-being may be useful to prevent the intersecting concerns of violence and HIV among FSW.

RESUMO

BACKGROUND: Existing best practices to monitor and prevent health care-associated infections (HAIs) were ineffective during the COVID-19 pandemic due to increased patient susceptibility toward infections, reduced resources, and increased use of agency nurses. PROBLEM: A review of the US hospitals revealed a 60% increase in central line-associate bloodstream infections (CLABSIs) and a 43% increase in catheter-associated urinary tract infections (CAUTIs) in 2020. A large, academic, level 1 trauma center in Houston, Texas, experienced similar challenges at the start of the COVID-19 pandemic. APPROACH: An interdisciplinary team of nurses, infection preventionists, and hospital educators combined and adapted existing evidence-based practices in a novel way to create a nursing-led toolkit for quality improvement tracking, improving, and sustaining HAI improvements. OUTCOMES: CLABSI and CAUTI rates were reduced over time following the introduction of the Nurse-Sensitive Indicator Quality Improvement (NSIQI) Toolkit. The CLABSI standardized infection ratio (SIR) decreased by 19%, and the CAUTI SIR decreased by 19.4%. CONCLUSIONS: The novel NSIQI Toolkit is a scalable tool for improving and sustaining CLABSI and CAUTI rates, which may have the potential for other nurse-sensitive quality indicators.

RESUMO

BACKGROUND: Whole genome sequencing of cultured pathogens is the state of the art public health response for the bioinformatic source tracking of illness outbreaks. Quasimetagenomics can substantially reduce the amount of culturing needed before a high quality genome can be recovered. Highly accurate short read data is analyzed for single nucleotide polymorphisms and multi-locus sequence types to differentiate strains but cannot span many genomic repeats, resulting in highly fragmented assemblies. Long reads can span repeats, resulting in much more contiguous assemblies, but have lower accuracy than short reads. RESULTS: We evaluated the accuracy of Listeria monocytogenes assemblies from enrichments (quasimetagenomes) of naturally-contaminated ice cream using long read (Oxford Nanopore) and short read (Illumina) sequencing data. Accuracy of ten assembly approaches, over a range of sequencing depths, was evaluated by comparing sequence similarity of genes in assemblies to a complete reference genome. Long read assemblies reconstructed a circularized genome as well as a 71 kbp plasmid after 24 h of enrichment; however, high error rates prevented high fidelity gene assembly, even at 150X depth of coverage. Short read assemblies accurately reconstructed the core genes after 28 h of enrichment but produced highly fragmented genomes. Hybrid approaches demonstrated promising results but had biases based upon the initial assembly strategy. Short read assemblies scaffolded with long reads accurately assembled the core genes after just 24 h of enrichment, but were highly fragmented. Long read assemblies polished with short reads reconstructed a circularized genome and plasmid and assembled all the genes after 24 h enrichment but with less fidelity for the core genes than the short read assemblies. CONCLUSION: The integration of long and short read sequencing of quasimetagenomes expedited the reconstruction of a high quality pathogen genome compared to either platform alone. A new and more complete level of information about genome structure, gene order and mobile elements can be added to the public health response by incorporating long read analyses with the standard short read WGS outbreak response.

RESUMO

Despite recent advances in Salmonella-sprout research, little is known about the relationship between Salmonella and the sprout microbiome during sprouting. Sprout spent irrigation water (SSIW) provides an informative representation of the total microbiome of this primarily aquaponic crop. This study was designed to characterize the function and taxonomy of the most actively transcribed genes in SSIW from Salmonella enterica serovar Cubana-contaminated alfalfa seeds throughout the sprouting process. Genomic DNA and total RNA from SSIW was collected at regular intervals and sequenced using Illumina MiSeq and NextSeq platforms. Nucleic acid data were annotated using four different pipelines. Both metagenomic and metatranscriptomic analyses revealed a diverse and highly dynamic SSIW microbiome. A "core" SSIW microbiome comprised Klebsiella, Enterobacter, Pantoea, and Cronobacter The impact, however, of Salmonella contamination on alfalfa seeds influenced SSIW microbial community dynamics not only structurally but also functionally. Changes in genes associated with metabolism, genetic information processing, environmental information processing, and cellular processes were abundant and time dependent. At time points of 24 h, 48 h, and 96 h, totals of 541, 723, and 424 S Cubana genes, respectively, were transcribed at either higher or lower levels than at 0 h in SSIW during sprouting. An array of S Cubana genes (107) were induced at all three time points, including genes involved in biofilm formation and modulation, stress responses, and virulence and tolerance to antimicrobials. Taken together, these findings expand our understanding of the effect of Salmonella seed contamination on the sprout crop microbiome and metabolome.IMPORTANCE Interactions of human enteric pathogens like Salmonella with plants and plant microbiomes remain to be elucidated. The rapid development of next-generation sequencing technologies provides powerful tools enabling investigation of such interactions from broader and deeper perspectives. Using metagenomic and metatranscriptomic approaches, this study identified not only changes in microbiome structure of SSIW associated with sprouting but also changes in the gene expression patterns related to the sprouting process in response to Salmonella contamination of alfalfa seeds. This study advances our knowledge on Salmonella-plant (i.e., sprout) interaction.

RESUMO

Freshwater can support the survival of the enteric pathogen Salmonella, though temporal Salmonella diversity in a large watershed has not been assessed. At 28 locations within the Susquehanna River basin, 10-liter samples were assessed in spring and summer over 2 years. Salmonella prevalence was 49%, and increased river discharge was the main driver of Salmonella presence. The amplicon-based sequencing tool, CRISPR-SeroSeq, was used to determine serovar population diversity and detected 25 different Salmonella serovars, including up to 10 serovars from a single water sample. On average, there were three serovars per sample, and 80% of Salmonella-positive samples contained more than one serovar. Serovars Give, Typhimurium, Thompson, and Infantis were identified throughout the watershed and over multiple collections. Seasonal differences were evident: serovar Give was abundant in the spring, whereas serovar Infantis was more frequently identified in the summer. Eight of the ten serovars most commonly associated with human illness were detected in this study. Crucially, six of these serovars often existed in the background, where they were masked by a more abundant serovar(s) in a sample. Serovars Enteritidis and Typhimurium, especially, were masked in 71 and 78% of samples where they were detected, respectively. Whole-genome sequencing-based phylogeny demonstrated that strains within the same serovar collected throughout the watershed were also very diverse. The Susquehanna River basin is the largest system where Salmonella prevalence and serovar diversity have been temporally and spatially investigated, and this study reveals an extraordinary level of inter- and intraserovar diversity.IMPORTANCESalmonella is a leading cause of bacterial foodborne illness in the United States, and outbreaks linked to fresh produce are increasing. Understanding Salmonella ecology in freshwater is of importance, especially where irrigation practices or recreational use occur. As the third largest river in the United States east of the Mississippi, the Susquehanna River is the largest freshwater contributor to the Chesapeake Bay, and it is the largest river system where Salmonella diversity has been studied. Rainfall and subsequent high river discharge rates were the greatest indicators of Salmonella presence in the Susquehanna and its tributaries. Several Salmonella serovars were identified, including eight commonly associated with foodborne illness. Many clinically important serovars were present at a low frequency within individual samples and so could not be detected by conventional culture methods. The technologies employed here reveal an average of three serovars in a 10-liter sample of water and up to 10 serovars in a single sample.

RESUMO

BACKGROUND: Emergency situations, including epidemics, increase incidence of violence against women, especially intimate partner violence (IPV). This paper describes specific scenarios of IPV reported by women during the COVID-19 pandemic in Nigeria to provide insight for policy and programmatic efforts. METHODS: This paper draws on seven de-identified case reports from organisations serving women experiencing IPV as well as media coverage of IPV cases in Nigeria, between April and May, 2020. RESULTS: In most cases, reports identified IPV that was occurring prior to the lockdown, but increased in severity or involved new types of violence during the lockdown. The case scenarios included descriptions of many forms of IPV commonly reported, including physical, economic, psychological and sexual violence, often concurrently. Several women also reported threats of being thrown out of their homes by perpetrators, which threatens women's ability to protect themselves from exposure to COVID-19, but could also leave women stranded with no access to transportation, social services, or other resources during the lockdown. Several women also reported IPV that involved custody of children, as well as IPV that disrupted women's income generation. IPV was also reported in relation to economic stressors associated with the lockdown. Reports highlight how the lockdown disrupted women's social support, hindering accessibility of formal and informal sources of help. CONCLUSION: The lockdowns in Nigeria may have inadvertently placed women already experiencing partner violence at risk for experiencing more severe violence, new challenges to cope with violent experiences, and other forms of violence, including violence that used the lockdown as a way to threaten women's security and ability to protect themselves from the virus. Hence, there is need for innovative approaches to support victims, with emphasis on ways in which perpetrators of IPV may be using the threat of COVID-19 to further gain power and control over partners.

RESUMO

BACKGROUND: Afar region is one of the pastoralist dominated regions in Ethiopia. The region is characterized by a low contraceptive prevalence rate (CPR) of 5.4%. Lack of awareness of contraceptive use, husband objection and religious barriers are attributed to low CPR in the region. This study assessed the effect of community-based interventions for promoting family planning (FP) use among pastoralist communities in Ethiopia. METHODS: The study design was a three-arm, parallel, clustered randomized controlled trial (CRT). The three study arms were: (1) male involvement in family planning (FP) education; (2) women's education on FP; and (3) control. A total of 33 clusters were randomized and allocated with a one-to-one ratio. Intervention components included (1) health education on FP to married women and men by faema leaders (a traditional community-based structure that serves as a social support group); (2) video-assisted message on FP; and (3) assisting the faema leader using health workers and health extension workers (HEWs). The intervention was given for a total of nine months. FP use and intentions were measured as outcome variables. In addition, a cluster-level summary considering a cluster effect analysis was performed. The result was presented with t.test, adjusted risks and its 95% confidence interval (CI). RESULTS: The proportion of FP use among the arms was 34% in the male involvement in FP education, 17.5% in women's education on FP and 4.3% in the control. There was a positive change in the proportion of FP use in the male involvement in FP education and women's education on FP arms with absolute risk (AR) of 0.29 (95% CI, 0.23,0.34) and 0.13 (95% CI,0.08,0.17), respectively, as compared to the control arm. Similarly, married women in the male involvement in FP education and women's education on FP arms had 3.4 (2.48, 4.91) and 2.1 (1.50, 2.95) higher intention to use FP, respectively, as compared with the control arm. CONCLUSION: The present study suggests that in such male-dominated pastoralist communities with more considerable religious barriers, the community-based health education mainly targeting males appears to be a promising strategy for improving FP use and intention to use FP.

RESUMO

Cantaloupes have emerged as significant vehicles of widespread foodborne illness outbreaks caused by bacterial pathogens, including Salmonella. The purpose of this study was to investigate the efficiency of Salmonella colonization and internalization in cantaloupes by relevant routes of contamination. Cantaloupe plants (Cucumis melo 'reticulatus') from two cultivars 'Athena' (Eastern) and 'Primo' (Western) were grown from commercial seed. Plants were maintained in the NCSU BSL-3P phytotron greenhouse. Salmonella enterica (a cocktail of cantaloupe-associated outbreak serovars Javiana, Newport, Panama, Poona and Typhimurium) contamination was introduced via blossoms or soil at ca. 4.4 log10 CFU/blossom or 8.4 log10 CFU/root zone, respectively. Cantaloupes were analyzed for Salmonella by enrichment in accordance with modified FDA-BAM methods. Five randomly chosen colonies from each Salmonella-positive sample were typed using the Agilent 2100 bioanalyzer following multiplex PCR. Data were analyzed for prevalence of contamination and serovar predominance in fruit, stems and soil. Of the total cantaloupe fruit harvested from Salmonella-inoculated blossoms (n = 63), 89% (56/63) were externally contaminated and 73% (46/63) had Salmonella internalized into the fruit. Serovar Panama was the most commonly isolated from the surface of fruit while S. Panama and S. Poona were the most prevalent inside the fruit. When soil was inoculated with Salmonella at one day post-transplant, 13% (8/60) of the plants were shown to translocate the organism to the lower stem (ca. 4 cm) by 7 days post-inoculation (dpi). We observed Salmonella persistence in the soil up to 60 dpi with S. Newport being the predominant serovar at 10 and 20 dpi. These data demonstrate that contaminated soil and blossoms can lead to Salmonella internalization into the plant or fruit at a relatively high frequency.

RESUMO

BACKGROUND: Married adolescent girls are vulnerable to risky sexual and reproductive health outcomes. We examined the association of fertility pressure from in-laws' early in marriage with contraceptive use ever, parity, time until first birth, and couple communication about family size, among married adolescent girls. METHODS: Data were taken from a cross-sectional survey with married girls aged 15-19 years (N = 4893) collected from September 2015 to July 2016 in Bihar and Uttar Pradesh, India. Multivariable regression assessed associations between in-laws' fertility pressure and each outcome, adjusting for sociodemographic covariates. RESULTS: We found that 1 in 5 girls experienced pressure from in-laws' to have a child immediately after marriage. In-laws' fertility pressure was associated with lower parity (Adj. ß Coef. - 0.10, 95% CI - 0.17, - 0.37) and couple communication about family size (AOR = 1.77, 95% CI 1.39, 2.26), but not contraceptive use or time until birth. CONCLUSIONS: Our study adds to the literature identifying that in-laws' pressure on fertility is common, affects couple communication about family size, and may be more likely for those yet to have a child, but may have little effect impeding contraceptive use in a context where such use is not normative.

RESUMO

OBJECTIVE: Women's involvement in contraceptive decision-making increases contraceptive use and reduces unmet need, but study of this has been limited to women's self-reports. Less research is available examining couple concordance and women's involvement in contraceptive decision-making as reported by both men and women. STUDY DESIGN: We carried out a cross-sectional study using data from rural India (N = 961 young married couples). Using multivariable regression we examined the association between concordance or discordance in spousal reports of wife's involvement in contraceptive decision-making and modern contraceptive use, adjusting for demographics, intimate partner violence, and contraceptive use discussion. RESULTS: More than one third (38.3%) of women reported current modern contraceptive use. Report of women's involvement in contraceptive decision-making showed 70.3% of couples agreed that women were involved, jointly or alone (categorized as Concordant 1), 4.2% agreed women were not involved (categorized at Concordant 2), 13.2% had women report involvement but men report women were uninvolved (categorized as Discordant 1), and 12.2% had women report uninvolvement but men report that women were involved (categorized as Discordant 2). Discordant 2 couples had lower odds of modern contraceptive use relative to Concordant 1 couples (adjusted RR = 0.61, 95% CI 0.45-0.83). No other significant differences between Concordant 1 couples and other categories were observed. CONCLUSION: One in four couples indicated discordance on women's involvement in contraceptive decision making, with Discordant 2 category having lower odds of contraceptive use. Couples' concordance in women's involvement in contraceptive decision-making offers a target for family planning research and interventions to better meet their needs. Trial registration ClinicalTrial.gov, NCT03514914. https://clinicaltrials.gov/ct2/show/NCT03514914.


Evidence on women's involvement in decision-making are limited to women's self reports and often not specific to contraceptive decision-making. This study uses couples dyadic data to assess male­female concordance on women's involvement in contraceptive decision-making and contraceptive use outcomes. Couple's concordance on women's involvement in contraceptive decision-making is associated with contraceptive use. There is potential in couple-focused family planning counseling that enhances women's contraceptive decision-making agency to improve women's contraceptive use.

RESUMO

INTRODUCTION: This study explored the motivations for and relationship dynamics that may promote girls' vulnerability for intimate partner violence and sources of support reported in unhealthy relationships among girls residing in low-income communities in Ibadan, Nigeria. METHODS: Focus group discussions (n = 14; 122 girls) were conducted among girls aged 15-19 years, who reported having been in a relationship lasting at least 3 months. Girls were recruited from schools and worksites where partner violence has been reported in high proportions. Data were analysed using conceptual content analyses and independently coded by two researchers. RESULTS: Adolescent girls reported keeping their relationships secret from their parents. While girls reported that sometimes relationships were out of love, relationships were also often motivated by girls' financial need. The financial and secretive nature of these relationships appeared to place girls at risk for intimate partner violence, with sexual coercion, resulting in multiple adverse social and health outcomes, including sexually transmitted infections and unintended pregnancy. Girls reported that leaving an abusive relationship is especially difficult when girls rely financially, were sexually involved, pregnant, or have had a child with the male partner. Friends/peers, rather than girls' family, were often the source of support for intimate partner violence. CONCLUSION: Early identification of unhealthy relationships and supporting girls to be financially independent appear to be critical to reduce vulnerability to violence. Peer-based interventions may be most appropriate, given that girls' friends, rather than parents, were most often the source of support for intimate partner violence and other relationship challenges.

RESUMO

BACKGROUND: Full chloroplast genomes provide high resolution taxonomic discrimination between closely related plant species and are quickly replacing single and multi-locus barcoding regions as reference materials of choice for DNA based taxonomic annotation of plants. Bixa orellana, commonly known as "achiote" and "annatto" is a plant used for both human and animal foods and was thus identified for full chloroplast sequencing for the Center for Veterinary Medicine (CVM) Complete Chloroplast Animal Feed database. This work was conducted in collaboration with the Instituto de Medicina Tradicional (IMET) in Iquitos, Peru. There is a wide range of color variation in pods of Bixa orellana for which genetic loci that distinguish phenotypes have not yet been identified. Here we apply whole chloroplast genome sequencing of "red" and "yellow" individuals of Bixa orellana to provide high quality reference genomes to support kmer database development for use identifying this plant from complex mixtures using shotgun data. Additionally, we describe chloroplast gene content, synteny and phylogeny, and identify an indel and snp that may be associated with seed pod color. RESULTS: Fully assembled chloroplast genomes were produced for both red and yellow Bixa orellana accessions (158,918 and 158,823 bp respectively). Synteny and gene content was identical to the only other previously reported full chloroplast genome of Bixa orellana (NC_041550). We observed a 17 base pair deletion at position 58,399-58,415 in both accessions, relative to NC_041550 and a 6 bp deletion at position 75,531-75,526 and a snp at position 86,493 in red Bixa orellana. CONCLUSIONS: Our data provide high quality reference genomes of individuals of red and yellow Bixa orellana to support kmer based identity markers for use with shotgun sequencing approaches for rapid, precise identification of Bixa orellana from complex mixtures. Kmer based phylogeny of full chloroplast genomes supports monophylly of Bixaceae consistent with alignment based approaches. A potentially discriminatory indel and snp were identified that may be correlated with the red phenotype.

RESUMO

Research in Uganda examining HIV-positive status disclosure and IPV victimization is scarce, and existing findings may not generalize to community-based samples of men and women newly diagnosed with HIV in Uganda. We investigated the prevalence of lifetime IPV, IPV experienced between HIV diagnosis and 6 months following diagnosis (recent IPV), and IPV specifically related to a partner learning one's HIV-positive status among a sample of men and women newly diagnosed with HIV in a population-based study in rural Uganda. We also examined correlates of recent IPV, including HIV-positive status disclosure. The sample included 337 participants followed for 6 months after HIV diagnosis. Lifetime IPV findings showed that over half of the sample reported experiencing emotional IPV (62.81% of men, 70.37% of women), followed by physical IPV (21.49% of men, 26.39% of women) then sexual IPV (7.44% of men, 17.59% of women). For recent IPV, men and women reported similar rates of physical (4.63% and 8.29%, respectively) and emotional (19.44% and 25.91%, respectively) IPV. Women were more likely than men to report recent sexual IPV (8.29% vs. 1.85%); however, this relationship was no longer significant after controlling for other risk factors associated with sexual IPV (AOR = 3.47, 95% CI [0.65, 18.42]). Participants who disclosed their HIV-positive status to their partner had 59% lower odds of reporting emotional IPV (AOR = 0.41, 95% CI [0.21, 0.81]) than participants who did not disclose their HIV-positive status. Younger age, non-polygamous marriage, lower social support, and greater acceptance for violence against women were also significantly associated with experience of recent IPV. Overall, 12.20% of participants who experienced recent IPV reported that the IPV was related to their partner learning their HIV-positive status. Findings highlight the need for IPV screening and intervention integrated into HIV diagnosis, care, and treatment services.

RESUMO

BACKGROUND: The more quickly bacterial pathogens responsible for foodborne illness outbreaks can be linked to a vehicle of transmission or a source, the more illnesses can be prevented. Whole genome sequencing (WGS) based approaches to source tracking have greatly increased the speed and resolution with which public health response can pinpoint the vehicle and source of outbreaks. Traditionally, WGS approaches have focused on the culture of an individual isolate before proceeding to DNA extraction and sequencing. For Listeria monocytogenes (Lm), generation of an individual isolate for sequencing typically takes about 6 days. Here we demonstrate that a hybrid, "quasimetagenomic" approach ie; direct sequencing of microbiological enrichments (first step in pathogen detection and recovery) can provide high resolution source tracking sequence data, 5 days earlier than response that focuses on culture and sequencing of an individual isolate. This expedited approach could save lives, prevent illnesses and potentially minimize unnecessary destruction of food. METHODS: Naturally contaminated ice cream (from a 2015 outbreak) was enriched to recover Listeria monocytogenes following protocols outlined in the Bacteriological Analytic Manual (BAM). DNA from enriching microbiota was extracted and sequenced at incremental time-points during the first 48 h of pre-enrichment using the Illumina MiSeq platform (2 by 250), to evaluate genomic coverage of target pathogen, Listeria monocytogenes. RESULTS: Quasimetagenomic sequence data acquired from hour 20 were sufficient to discern whether or not Lm strain/s were part of the ongoing outbreak or not. Genomic data from hours 24, 28, 32, 36, 40, 44, and 48 of pre-enrichments all provided identical phylogenetic source tracking utility to the WGS of individual isolates (which require an additional 5 days to culture). CONCLUSIONS: The speed of this approach (more than twice as fast as current methods) has the potential to reduce the number of illnesses associated with any given outbreak by as many as 75% percent of total cases and potentially with continued optimization of the entire chain of response, contribute to minimized food waste.

RESUMO

BACKGROUND: Pastoralist community, Afar, women felt that they are embedded in strong cultural and religious perspectives which promotes a high number of children, and discourages family planning (FP) use. They are multifaced factors which hinder women not to use FP and it is time to develop a context-based tool to understand the situation at the ground. However, we have a dearth of evidence on a reliable and valid tool. Therefore, this study aims in developing a reliable and valid tool that considers the women's knowledge, male involvement, attitude, and belief about whether most people approve or disapprove of the behavior to use or not use of FP. METHODS: A total of 891 married women participated in the study. Reviewing the literature, piloting, pretesting, and collecting the actual data were the steps we used to develop a reliable and valid tool. We used the integrated behavioral model (IBM) as a conceptual framework for developing the tool. The developing tool consists of 1) knowledge 2) perceived male involvement and 3) constructs of integrated behavioral model (IBM); expressional and instrumental attitude, subjective norm, self-efficacy, perceived control and intention to use of FP. The IBM items composed of direct and indirect measurement. In the analysis of the data, exploratory and confirmatory factor analysis was done. Independent t. test with cohen's d was used to calculate the effect size. The correlation coefficient was carried between the direct and indirect measurements of the items of the integrated behavioral model (IBM). RESULTS: A total of 891 pastoralist married women were included in the analysis of the reliability and validity of the tool. The mean age of the participants was 26.74(±6.45). The KMO value for all items was greater than 0.83 with a Bartlett test of sphericity of (p < 0.00). Thirteen items were used to measure the knowledge of the respondent towards FP use. The tool had 64.92 variances explained and Cronbach alpha of 0.85. Acceptable values of the fitness indices were obtained in the confirmatory factor analysis (CFA) The items of knowledge towards FP had normed chi-square of 4.5, RMSEA with 90% CI of 0.064(0.056,.0.071), SRMR of 0.039, CFI of 0.969 and TLI of 0961. All the developed items had a Cohen's d ranges from 0.5 to 2. Moreover, the correlation test of the IBM ranges from 0.6 to 0.7 which shows a higher correlation between the measurement direct and indirect items. CONCLUSION: The pastoralist community version of the FP questionnaire is a valid and reliable tool and can be used to measure future family planning use. The indirect measurement of the IBM constructs was a good item to measure FP. However, as a limitation of the study respondents may face difficulty in realizing the difference one item to another especially when items on the scale look so similar to her.
