Does Postanesthesia Forced-Air Warming Affect Emergence Delirium in Pediatric Patients Receiving Daily Anesthesia?

PURPOSE: To determine if postanesthesia forced-air warming as a nonpharmacologic intervention for emergence delirium (ED)/emergence agitation (EA) decreased the incidence and severity of ED in children aged 18 months to 6 years old. DESIGN: Prospective nonrandomized controlled trial. METHODS: Participants included children aged 18 months to 6 years old receiving general anesthesia within a radiation oncology setting. Status of ED/EA was based on the participants' Pediatric Anesthesia Emergence Delirium (PAED) scale score (two consecutive scores greater than 10 out of 20) or inconsolable agitation behaviors post computed tomography simulation (day 0). Interrater reliability was conducted among the center's perianesthesia care nurses. Participants who scored positive for ED/EA received a forced-air warming blanket for the remainder of treatment with data collection 1 to 14 days postanesthesia. Non-ED/EA participants were followed for 14 days and provided forced-air warming if ED/EA occurred. Data consisted of daily PAED scores and self- or parent-report on the anxiety scale. If the participants received forced-air warming, nurses' clinical observations and parent satisfaction surveys were collected 3 times during the 14-day study period. FINDINGS: A total of 59 participants completed the study (mean age 3.43 years; 60% male; 63% non-Hispanic White); 16 were identified with ED or EA (mean age 3.56 years; 50% male; 69% non-Hispanic White) with an incidence rate of 28%. For the 16 participants with ED/EA, the primary diagnosis consisted of solid tumors and an American Society of Anesthesia Classification III to IV. Prior to the forced-air warming intervention, all 16 participants exhibited inconsolable ED/EA behaviors, including 8 who had PAED scores greater than 10. ED/EA behaviors expressed included inconsolability, confusion, thrashing, and combativeness. Within the 14-day period, 3 participants received forced-air warming on day 1, while the other 13 received an average of 4.23 days of treatment (range 1 to 11 days; mode 1 day; median 4 days). Comparison of PAED scores pre (mean 4.4) and post (mean 1.8) indicated that the use of forced-air warming was statistically significant (P = .001). ED/EA behaviors and PAED scores after the forced-air warming period decreased in all but one participant. Some agitation behaviors were not captured within the PAED score. CONCLUSIONS: Forced-air warming impacted PAED scores and agitation behaviors for studied participants, offering a safe, nonpharmacological nursing intervention that may be an effective tool for helping to manage this baffling condition.

Candidatus Kirkpatrickella diaphorinae gen. nov., sp. nov., an uncultured endosymbiont identified in a population of Diaphorina citri from Hawaii.

Diaphorina citri is the hemipteran pest and vector of a devastating bacterial pathogen of citrus worldwide. In addition to the two core bacterial endosymbionts of D. citri, Candidatus Carsonella ruddii and Candidatus Profftella armatura, the genome of a novel endosymbiont and as of yet undescribed microbe was discovered in a Hawaiian D. citri population through deep sequencing of multiple D. citri populations. Found to be closely related to the genus Asaia in the family Acetobacteraceae by 16S rRNA gene sequence analysis, it forms a sister clade along with other insect-associated 16S rRNA gene sequences from uncultured bacterium found associated with Aedes koreicus and Sogatella furcifera. Multilocus sequence analysis confirmed the phylogenetic placement sister to the Asaia clade. Despite the culturable Asaia clade being the closest phylogenetic neighbour, attempts to culture this newly identified bacterial endosymbiont were unsuccessful. On the basis of these distinct genetic differences, the novel endosymbiont is proposed to be classified into a candidate genus and species 'Candidatus Kirkpatrickella diaphorinae'. The full genome was deposited in GenBank (accession number CP107052; prokaryotic 16S rRNA OP600170).

Resolving the deep phylogeny: Implications for early adaptive radiation, cryptic, and present-day ecological diversity of Papuan microhylid frogs.

The microhylid frogs of the New Guinea region are the largest and most ecologically diverse subfamily (Asterophryinae) of one of the largest anuran families in the world and can live in communities of up to 20 species. While there has been recent progress in resolving the phylogenetic relationships of Asterophryinae, significant uncertainties remain, impeding further progress in understanding the evolution of microhabitat use, parental care, and life history variation in this group. In particular, the early divergences at the base of the tree remain unclear; as does the monophyly of some genera; and recent studies have discovered that species with wide geographic distribution are instead cryptic species complexes. In this study, we fortified geographic sampling of the largest previous phylogenetic effort by sequencing an additional 62 taxa and increased data quality and quantity by adding new layers of data vetting and by filling in previously incomplete loci to the five gene dataset (2 mitochondrial, 3 nuclear protein-coding genes) to obtain a dataset that is now 99% complete in over 2400 characters for 233 samples (205 taxa) of Asterophryinae and 3 outgroup taxa, and analyzed microhabitat use data for these taxa from field data and data collected from the literature. Importantly, our sampling includes complete community complements at 19 sites as well as representatives at over 80 sites across New Guinea and its offshore islands. We present a highly resolved molecular phylogeny which, for the first time, has over 95% of nodes supported (84% highly supported) whether using Maximum Likelihood or Bayesian Inference, allowing clarification of all genera (whether monophyletic or clearly not), their sister genera relationships, as well as an age estimate for the Asterophryinae at approximately 20MYA. Early generic diversification occurring between 17 and 12 MYA gave rise to a surprising diversity of about 18 genera as well as the 5 putative microhabitat types. Our tree reveals extensive cryptic diversity calling any widespread taxa into doubt, and clearly demonstrates that complex multispecies communities of Asterophryinae are ecologically diverse, are numerous, and of ancient origin across New Guinea. We discuss the implications of our phylogeny for explaining the explosive diversification of Asterophryinae as the result of adaptive radiation, niche conservatism, and non-adaptive radiation.

Partner support and women's contraceptive use: insight from urban poor communities in Accra, Ghana.

BACKGROUND: Despite the benefits associated with contraceptive use, there is a low prevalence of contraceptive use in sub-Saharan Africa and Ghana. Previous studies have partly and consistently attributed the low prevalence of contraceptive use to partner opposition. However, little is known about the influence of men in contraceptive related choices of their partners, particularly within the context of urban poverty. This study examines the influences of partners on women's contraceptive choices. METHODS: The study utilized a cross-sectional household survey data of 1578 currently married women and women in a union of reproductive ages 16-44 years. Women who were pregnant and those trying to be pregnant were excluded from the analysis. The dependent variables for the study were current use of any contraceptive method, types of contraceptive methods and types of modern contraceptive methods. The independent variable for the study was a woman's report of partner support in contraceptive related choices. A binary logistic regression model was used to examine the associations between partner support in contraceptive related choices and contraceptive use of women. RESULTS: The results of the study show that partner support of contraceptive related choices has a significant influence on contraceptive use of women. Women who indicated support from their partners were more likely to be current users of any contraceptive method, yet were less likely to use modern contraceptive methods. CONCLUSION: The study highlights the need to involve men in family planning programs and research, as well as educating them on the various contraceptive modern methods and the side effects.

Covert Contraceptive Use amongst the urban poor in Accra, Ghana: experiences of health providers.

BACKGROUND: An estimated one-third of women in Ghana use contraceptives without the knowledge of their partners, a phenomenon known as Covert Contraceptive Use (CCU). Most research on CCU to date has focused on individual women to the neglect of the role of health system. This study explores CCU in urban poor communities of Accra, Ghana, from the experiences and perspectives of health providers. METHODS: Qualitative in-depth interviews were conducted with health care providers in both the public and private sectors at multiple levels, from the community clinic to the tertiary hospital, to gain insights into the strategies women use and the ways in which the health system supports the practice of CCU. RESULTS: Five major thematic areas emerged: use of easily concealed-methods, discrete-access-and-information-keeping, time-of-day, non-verbal-communication and use of relationships. The study further revealed that fear, mistrust, shyness, myths, and misperceptions regarding contraceptives explain CCU among women in the communities that the providers serve. CONCLUSION: Importantly, disclosure of methods used by providers without women's consent could potentially lead to violent outcomes for both women and the providers. Our results highlight the pivotal role that providers play in confidentially supporting women's choices regarding the use of contraceptives.

Sometimes women use contraceptives without the knowledge of their sexual partners. That is to say, they hide their contraceptive use. Many studies have explored why women hide their contraceptive use. Reasons include the desire of men to have absolute control of their women's bodies including their sexuality and fertility regulation. This occurs in cultures where women do not have as much power as men. In Ghana, as much as one-in-three women hide their contraceptive use from their partners. This study explores the ways in which health facilities assist women to hide their contraceptives use by talking to leaders of units responsible for providing contraceptives in the hospitals. First, people prefer contraceptives like injectables that are not visible on the bodies of those using them. Second, some hospitals have modified their space to provide ample privacy and security for women. Third, some women visit the facilities at odd hours, such as very early in the morning, very late at night and at other favorable times. Sometimes nurses arrange to meet women outside the facility. Lastly, nurses create avenues through various personal relationships. For example, leaving their contacts in market spaces and arranging meeting places with market queens.

Dynamics of Emergency Contraceptive Use in Accra, Ghana.

Recent data suggest increasing rates of emergency contraception (EC) use in Ghana, particularly in urban areas. In 2018, we collected survey data from 3,703 sexually experienced women aged 16-44 years living in low-income settlements of Accra. We estimated the prevalence of lifetime and current EC use. Multivariate logistic regression was used to assess factors associated with current use of EC. Retrospective monthly calendar data on contraceptive use were analyzed to identify patterns of EC use, including repeat and continuous use, and uptake of other contraceptive methods in the months following EC use. Nearly 15 percent of women had ever used EC. About half of recent EC users (52 percent) used EC for at least four months cumulatively within a 12-month window. There was no evidence of adoption of other modern methods in the months after using EC. Our results suggest that EC is a common method for pregnancy prevention in Accra, particularly among young, unmarried, highly educated women. Counseling on effective EC use and strategies that promote equitable access should be prioritized.

Methods women use for induced abortion and sources of services: insights from poor urban settlements of Accra, Ghana.

BACKGROUND: Increasing access to safe abortion methods is crucial for improving women's health. Understanding patterns of service use is important for identifying areas for improvement. Limited evidence is available in Ghana on factors associated with the type of method used to induce abortion. This paper examined the methods and sources of services used for abortion by women living in poor urban settings of Accra. METHODS: Data are from a survey that was conducted in 2018 among 1233 women aged 16-44 years who reported ever having had an induced abortion. We estimated a multinomial logistic regression model to examine factors associated with the type of abortion methods women used. We further generated descriptive statistics for the source of abortion services. RESULTS: About 50% women used surgical procedures for their last abortion, 28% used medication abortion (MA), 12% used other pills, 3% used injection, and 7% used non-medical methods. However, nearly half (46%) of the women who terminated a pregnancy within the year preceding the survey used medication abortion (MA), 32% used surgical procedures, while 5% used non-medical methods. Women who terminated a pregnancy within three years preceding the survey had a 60% lower chance of using surgical procedures if they did not use MA compared to those who terminated a pregnancy more than 3 years before the survey (Relative Risk Ratio [RRR] 0.4; 95% CI 0.3-0.5). The vast majority (74%) of women who used MA obtained services from pharmacies. CONCLUSIONS: The use of MA pills to terminate pregnancies has increased in recent years in Ghana and these pills are mostly accessed from pharmacies. This suggests a need for a review of the national guidelines to include pharmacists and chemists in the provision of MA services.

Contraception before and after induced abortion: Trajectories of women in selected urban-poor settlements of Accra, Ghana.

This paper examined women's pre- and post-induced abortion contraceptive use and predictors of post-abortion modern contraceptive uptake in selected poor settlements of Accra, Ghana. Data from a cross-sectional study of 251 women aged 16-44 years were used. Patterns of contraceptive use were analysed descriptively while the predictors of modern contraceptive use in the month following induced abortion were examined using a binary logistic regression model. Majority of women (60%) were not using any method of contraception when they became pregnant before their abortion. Just over 30% of these women switched to using any method in the month immediately after abortion (22% modern and 9% traditional). Women who had became pregnant while using a modern method before their abortion had higher odds of using a modern method post-abortion than women who had not been using any method of contraception when they became pregnant. Following induced abortion, many women remained at potential risk of future unintended pregnancy. Our findings suggest the need for improved contraceptive counselling for women who seek abortion services, both during post-abortion care for facility-based abortions or at the time of obtaining medication abortion pills for those who are self-managing their abortion.

Direct and Indirect Visualization of Bacterial Effector Delivery into Diverse Plant Cell Types during Infection.

To cause disease, diverse pathogens deliver effector proteins into host cells. Pathogen effectors can inhibit defense responses, alter host physiology, and represent important cellular probes to investigate plant biology. However, effector function and localization have primarily been investigated after overexpression in planta. Visualizing effector delivery during infection is challenging due to the plant cell wall, autofluorescence, and low effector abundance. Here, we used a GFP strand system to directly visualize bacterial effectors delivered into plant cells through the type III secretion system. GFP is a beta barrel that can be divided into 11 strands. We generated transgenic Arabidopsis thaliana plants expressing GFP1-10 (strands 1 to 10). Multiple bacterial effectors tagged with the complementary strand 11 epitope retained their biological function in Arabidopsis and tomato (Solanum lycopersicum). Infection of plants expressing GFP1-10 with bacteria delivering GFP11-tagged effectors enabled direct effector detection in planta. We investigated the temporal and spatial delivery of GFP11-tagged effectors during infection with the foliar pathogen Pseudomonas syringae and the vascular pathogen Ralstonia solanacearum Thus, the GFP strand system can be broadly used to investigate effector biology in planta.

Evaluating implementation effectiveness and sustainability of a maternity waiting homes intervention to improve access to safe delivery in rural Zambia: a mixed-methods protocol.

BACKGROUND: In low-income countries such as Zambia, where maternal mortality rates are persistently high, maternity waiting homes (MWHs) represent one potential strategy to improve access to safe delivery, especially for women living in remote areas. The Maternity Homes Access in Zambia project (MAHMAZ) is evaluating the impact of a MWH model on women's access to safe delivery in rural Zambia. There is a growing need to understand not only the effectiveness of interventions but also the effectiveness of their implementation in order to appropriately interpret outcomes. There is little evidence to guide effective implementation of MWH for both immediate uptake and to promote sustainability in this context. This protocol describes a study that aims to investigate the effectiveness of the implementation of MAHMAZ by not only documenting fidelity but also identifying factors that influence implementation success and affect longer-term sustainability. METHODS: This study will use mixed methods to evaluate the implementation effectiveness and sustainability of the MAHMAZ intervention. In our study, "implementation effectiveness" means to expand beyond measuring fidelity to the MWH model and includes assessing both the adoption and uptake of the model and identifying those factors that facilitate or inhibit uptake. Sustainability is defined as the routine implementation of an intervention after external support has ended. Quantitative methods include extracting data from existing records at the MWHs and health facilities to analyze patterns of utilization, and conducting a routine health facility assessment to determine facility-level factors that may influence MWH implementation and woman-level outcomes. We will also conduct an experience survey with MWH users and apply a checklist to assess fidelity to the MWH model. Qualitative methods include in-depth interviews and focus group discussions with MWH users, community members and other stakeholders. Qualitative data will be analyzed using an integrated framework drawing constructs from the Consolidated Framework for Implementation Research and the Conceptual Framework for Sustainability. DISCUSSION: The findings from this evaluation will be shared with policymakers formulating policy affecting the implementation of MWH and may be used as evidence for programmatic decisions by the government and supporting agencies in deciding to take this model to scale.

Beyond glycolysis: GAPDHs are multi-functional enzymes involved in regulation of ROS, autophagy, and plant immune responses.

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is an important enzyme in energy metabolism with diverse cellular regulatory roles in vertebrates, but few reports have investigated the importance of plant GAPDH isoforms outside of their role in glycolysis. While animals possess one GAPDH isoform, plants possess multiple isoforms. In this study, cell biological and genetic approaches were used to investigate the role of GAPDHs during plant immune responses. Individual Arabidopsis GAPDH knockouts (KO lines) exhibited enhanced disease resistance phenotypes upon inoculation with the bacterial plant pathogen Pseudomonas syringae pv. tomato. KO lines exhibited accelerated programmed cell death and increased electrolyte leakage in response to effector triggered immunity. Furthermore, KO lines displayed increased basal ROS accumulation as visualized using the fluorescent probe H2DCFDA. The gapa1-2 and gapc1 KOs exhibited constitutive autophagy phenotypes in the absence of nutrient starvation. Due to the high sequence conservation between vertebrate and plant cytosolic GAPDH, our experiments focused on cytosolic GAPC1 cellular dynamics using a complemented GAPC1-GFP line. Confocal imaging coupled with an endocytic membrane marker (FM4-64) and endosomal trafficking inhibitors (BFA, Wortmannin) demonstrated cytosolic GAPC1 is localized to the plasma membrane and the endomembrane system, in addition to the cytosol and nucleus. After perception of bacterial flagellin, GAPC1 dynamically responded with a significant increase in size of fluorescent puncta and enhanced nuclear accumulation. Taken together, these results indicate that plant GAPDHs can affect multiple aspects of plant immunity in diverse sub-cellular compartments.

Concurrent chemotherapy is associated with improved survival in elderly patients with bladder cancer undergoing radiotherapy.

BACKGROUND: The current study was conducted to compare the overall survival (OS) of concurrent chemoradiotherapy (CCRT) versus radiotherapy (RT) alone in elderly patients (those aged ≥80 years) with muscle-invasive bladder cancer (MIBC). METHODS: Patients aged ≥80 years with cT2-4, N0-3, M0 transitional cell MIBC who were treated with curative RT (60-70 Gray) or CCRT were identified in the National Cancer Data Base. Univariable and multivariable frailty survival analyses, as well as 1-to-1 propensity score matching, were used to isolate the association between CCRT and OS. RESULTS: A total of 1369 patients who were treated with RT from 2004 through 2013 met eligibility criteria: 739 patients (54%) received RT alone and 630 patients (46%) received CCRT. The median age of the patients was 84 years (range, 80-90 years). The median follow-up was 21 months. The 2-year OS rate was 48%. When comparing CCRT with RT alone, the 2-year OS rate was 56% versus 42% (P<.0001), respectively. Multivariable analysis demonstrated that CCRT (hazard ratio [HR], 0.74; 95% confidence interval [95% CI], 0.65-0.84 [P<.0001]) and a higher RT dose (HR, 0.78; 95% CI, 0.67-0.90 [P<.001]) were associated with improved OS. T4 disease was associated with worse OS (HR, 1.42; 95% CI, 1.15-1.76 [P = .001]). After using 1-to-1 propensity score matching, there remained an OS benefit for the use of CCRT (HR, 0.77; 95% CI, 0.67-0.90 [P<.001]). CONCLUSIONS: CCRT is associated with improved OS compared with the use of RT alone in elderly patients with MIBC, independent of Charlson-Deyo comorbidity score, suggesting that CCRT should be used in this population.

The influence of quality maternity waiting homes on utilization of facilities for delivery in rural Zambia.

BACKGROUND: Residential accommodation for expectant mothers adjacent to health facilities, known as maternity waiting homes (MWH), is an intervention designed to improve access to skilled deliveries in low-income countries like Zambia where the maternal mortality ratio is estimated at 398 deaths per 100,000 live births. Our study aimed to assess the relationship between MWH quality and the likelihood of facility delivery in Kalomo and Choma Districts in Southern Province, Zambia. METHODS: We systematically assessed and inventoried the functional capacity of all existing MWH using a quantitative facility survey and photographs of the structures. We calculated a composite score and used multivariate regression to quantify MWH quality and its association with the likelihood of facility delivery using household survey data collected on delivery location in Kalomo and Choma Districts from 2011-2013. RESULTS: MWH were generally in poor condition and composite scores varied widely, with a median score of 28.0 and ranging from 12 to 66 out of a possible 75 points. Of the 17,200 total deliveries captured from 2011-2013 in 40 study catchment area facilities, a higher proportion occurred in facilities where there was either a MWH or the health facility provided space for pregnant waiting mothers compared to those with no accommodations (60.7% versus 55.9%, p <0.001). After controlling for confounders including implementation of Saving Mothers Giving Life, a large-scale maternal health systems strengthening program, among women whose catchment area facilities had an MWH, those women with MWHs in their catchment area that were rated medium or high quality had a 95% increase in the odds of facility delivery than those whose catchment area MWHs were of poor quality (OR: 1.95, 95% CI 1.76, 2.16). CONCLUSIONS: Improving both the availability and the quality of MWH represents a potentially useful strategy to increasing facility delivery in rural Zambia.

A novel tool for assessing primary care quality at the point of care in Vietnam.

BACKGROUND: The development of improved primary care systems around the world has received increased attention as a step towards improved health care for all. Vietnam is engaged in efforts to improve health care quality with a focus on primary care and Family Medicine training. New methods of assessment are needed to accurately measure competency in primary care practice. METHODS: A behaviourally-anchored rating scale was developed focused on core primary care principles for use in direct observation at the site of primary care delivery. This assessment tool was implemented with trainees in Family Medicine and a cohort of physicians not trained in Family Medicine. RESULTS: The tool measured statistically significant differences in selected behaviours related to communication skills and comprehensiveness among Family Medicine trained physicians. No significant differences were measured in other primary care domains. CONCLUSION: This behaviourally-anchored rating scale is a feasible tool for use in direct observation of primary care practice delivery in developing settings. More work is needed to refine this tool and assess its sensitivity, validity and reliability.

Block of ATP-binding cassette B19 ion channel activity by 5-nitro-2-(3-phenylpropylamino)-benzoic acid impairs polar auxin transport and root gravitropism.

Polar transport of the hormone auxin through tissues and organs depends on membrane proteins, including some B-subgroup members of the ATP-binding cassette (ABC) transporter family. The messenger RNA level of at least one B-subgroup ABCB gene in Arabidopsis (Arabidopsis thaliana), ABCB19, increases upon treatment with the anion channel blocker 5-nitro-2-(3-phenylpropylamino)-benzoic acid (NPPB), possibly to compensate for an inhibitory effect of the drug on ABCB19 activity. Consistent with this hypothesis, NPPB blocked ion channel activity associated with ABCB19 expressed in human embryonic kidney cells as measured by patch-clamp electrophysiology. NPPB inhibited polar auxin transport through Arabidopsis seedling roots similarly to abcb19 mutations. NPPB also inhibited shootward auxin transport, which depends on the related ABCB4 protein. NPPB substantially decreased ABCB4 and ABCB19 protein levels when cycloheximide concomitantly inhibited new protein synthesis, indicating that blockage by NPPB enhances the degradation of ABCB transporters. Impairing the principal auxin transport streams in roots with NPPB caused aberrant patterns of auxin signaling reporters in root apices. Formation of the auxin-signaling gradient across the tips of gravity-stimulated roots, and its developmental consequence (gravitropism), were inhibited by micromolar concentrations of NPPB that did not affect growth rate. These results identify ion channel activity of ABCB19 that is blocked by NPPB, a compound that can now be considered an inhibitor of polar auxin transport with a defined molecular target.

Recognition of bacterial plant pathogens: local, systemic and transgenerational immunity.

Bacterial pathogens can cause multiple plant diseases and plants rely on their innate immune system to recognize and actively respond to these microbes. The plant innate immune system comprises extracellular pattern recognition receptors that recognize conserved microbial patterns and intracellular nucleotide binding leucine-rich repeat (NLR) proteins that recognize specific bacterial effectors delivered into host cells. Plants lack the adaptive immune branch present in animals, but still afford flexibility to pathogen attack through systemic and transgenerational resistance. Here, we focus on current research in plant immune responses against bacterial pathogens. Recent studies shed light onto the activation and inactivation of pattern recognition receptors and systemic acquired resistance. New research has also uncovered additional layers of complexity surrounding NLR immune receptor activation, cooperation and sub-cellular localizations. Taken together, these recent advances bring us closer to understanding the web of molecular interactions responsible for coordinating defense responses and ultimately resistance.

Molecular and phylogenetic datasets for the Asterophryinae frogs of New Guinea with additional data on lifestyle, geography, and elevation.

The data provided here are related to the article "Resolving the Deep Phylogeny: Implications for Early Adaptive Radiation, Cryptic, and Present-day Ecological Diversity of Papuan Microhylid Frogs" [1]. The dataset is based on 233 tissue samples of the subfamily Asteroprhyinae, with representatives from all recognized genera, in addition to three outgroup taxa. The sequence dataset contains over 2400 characters per sample for five genes: three nuclear (Seventh in Absentia (SIA), Brain Derived Neurotrophic Factor (BDNF), Sodium Calcium Exchange subunit-1 (NXC-1)), and two mitochondrial loci (Cytochrome oxidase b (CYTB), and NADH dehydrogenase subunit 4 (ND4)); and is 99% complete. New primers were designed for all loci and accession numbers for the raw sequence data are provided. The sequences are used with geological time calibrations to produce time-calibrated Bayesian inference (BI) and Maximum Likelihood (ML) phylogenetic reconstructions using BEAST2 and IQ-TREE. Lifestyle data (arboreal, scansorial, terrestrial, fossorial, semi-aquatic) were collected from the literature and field notes and used to infer ancestral character states for each lineage. Collection location and elevation data were used to verify sites where multiple species or candidate species co-occur. All sequence data, alignments, and associated metadata (voucher specimen number, species identification, type locality status, global positioning system [GPS] coordinates, elevation, site with species list, and lifestyle) as well as the code to produce all analyses and figures are provided.

Intended versus actual delivery location and factors associated with change in delivery location among pregnant women in Southern Province, Zambia: a prespecified secondary observational analysis of the ZamCAT.

OBJECTIVES: This prespecified, secondary analysis of the Zambia Chlorhexidine Application Trial (ZamCAT) aimed to determine the proportion of women who did not deliver where they intended, to understand the underlying reasons for the discordance between planned and actual delivery locations; and to assess sociodemographic characteristics associated with concordance of intention and practice. DESIGN: Prespecified, secondary analysis from randomised controlled trial. SETTING: Recruitment occurred in 90 primary health facilities (HFs) with follow-up in the community in Southern Province, Zambia. PARTICIPANTS: Between 15 February 2011 and 30 January 2013, 39 679 pregnant women enrolled in ZamCAT. SECONDARY OUTCOME MEASURES: The location where mothers gave birth (home vs HF) was compared with their planned delivery location. RESULTS: When interviewed antepartum, 92% of respondents intended to deliver at an HF, 6.1% at home and 1.2% had no plan. However, of those who intended to deliver at an HF, 61% did; of those who intended to deliver at home, only 4% did; and of those who intended to deliver at home, 2% delivered instead at an HF. Among women who delivered at home, women who were aged 25-34 and ≥35 years were more likely to deliver where they intended than women aged 20-24 years (adjusted OR (aOR)=1.31, 95% CI=1.11 to 1.50 and aOR=1.32, 95% CI=1.12 to 1.57, respectively). Women who delivered at HFs had greater odds of delivering where they intended if they received any primary schooling (aOR=1.34, 95% CI=1.09 to 1.72) or more than a primary school education (aOR=1.54, 95% CI=1.17 to 2.02), were literate (aOR=1.33, 95% CI=1.119 to 1.58), and were not in the lowest quintile of the wealth index. CONCLUSION: Discrepancies between intended and actual delivery locations highlight the need to go beyond the development of birth plans and exposure to birth planning messaging. More research is required to address barriers to achieving intentions of a facility-based childbirth. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT01241318).

High-quality, chromosome-scale genome assemblies: comparisons of three Diaphorina citri (Asian citrus psyllid) geographic populations.

The Asian citrus psyllid, Diaphorina citri, is the insect vector of the causal agent of huanglongbing (HLB), a devastating bacterial disease of commercial citrus. Presently, few genomic resources exist for D. citri. In this study, we utilized PacBio HiFi and chromatin confirmation contact (Hi-C) sequencing to sequence, assemble, and compare three high-quality, chromosome-scale genome assemblies of D. citri collected from California, Taiwan, and Uruguay. Our assemblies had final sizes of 282.67 Mb (California), 282.89 Mb (Taiwan), and 266.67 Mb (Uruguay) assembled into 13 pseudomolecules-a reduction in assembly size of 41-45% compared with previous assemblies which we validated using flow cytometry. We identified the X chromosome in D. citri and annotated each assembly for repetitive elements, protein-coding genes, transfer RNAs, ribosomal RNAs, piwi-interacting RNA clusters, and endogenous viral elements. Between 19,083 and 20,357 protein-coding genes were predicted. Repetitive DNA accounts for 36.87-38.26% of each assembly. Comparative analyses and mitochondrial haplotype networks suggest that Taiwan and Uruguay D. citri are more closely related, while California D. citri are closely related to Florida D. citri. These high-quality, chromosome-scale assemblies provide new genomic resources to researchers to further D. citri and HLB research.

Postpartum contraceptive initiation and use: Evidence from Accra, Ghana.

BACKGROUND: Postpartum contraceptive use reduces unintended pregnancies and results in better health outcomes for children and women. However, there is a dearth of knowledge on postpartum contraceptive use in Ghana, particularly among women in low-income urban settings. To shed light on strategies that might enhance access to postpartum family planning services in low-income urban settings, we examined contraceptive use among postpartum women in Accra, Ghana, at 1, 3, 6, and 12 months following the birth and the methods used. The predictors of modern contraceptive use in the 12-month postpartum period were also examined. METHODS: Data come from a cross-sectional survey conducted in 2018 among 624 women aged 16-44 years who reported giving birth in the past 13-31 months prior to the interview. We generated descriptive statistics to examine the prevalence of contraceptive use among postpartum women at 1, 3, 6, and 12 months after birth. We further estimated a binary logistic regression to examine the predictors of modern contraceptive use at 12 months postpartum. RESULTS: Forty percent of postpartum women never used any contraceptive method during 1 year after birth and of those who used a method, 40% relied on traditional methods. Moreover, 29% of women started using a method the immediate 1 month post-birth. Results further show that postpartum modern contraceptive uptake was positively associated with higher education, having more live births, and being currently in a union. CONCLUSIONS: Findings highlight that there may be opportunities to improve the quality of counseling during antenatal and postnatal care visits by clients to ensure fully informed choices regarding postpartum contraception. Community outreach by health providers/promoters or similar models should be promoted in low-income population settings to educate postpartum women on modern contraceptive use. Women who plan to use traditional methods should be provided with information on the consistent and correct use of these methods.
