Seasonal dynamics of Anopheles stephensi and its implications for mosquito detection and emergent malaria control in the Horn of Africa.

Invasion of the malaria vector Anopheles stephensi across the Horn of Africa threatens control efforts across the continent, particularly in urban settings where the vector is able to proliferate. Malaria transmission is primarily determined by the abundance of dominant vectors, which often varies seasonally with rainfall. However, it remains unclear how An. stephensi abundance changes throughout the year, despite this being a crucial input to surveillance and control activities. We collate longitudinal catch data from across its endemic range to better understand the vector's seasonal dynamics and explore the implications of this seasonality for malaria surveillance and control across the Horn of Africa. Our analyses reveal pronounced variation in seasonal dynamics, the timing and nature of which are poorly predicted by rainfall patterns. Instead, they are associated with temperature and patterns of land use; frequently differing between rural and urban settings. Our results show that timing entomological surveys to coincide with rainy periods is unlikely to improve the likelihood of detecting An. stephensi. Integrating these results into a malaria transmission model, we show that timing indoor residual spraying campaigns to coincide with peak rainfall offers little improvement in reducing disease burden compared to starting in a random month. Our results suggest that unlike other malaria vectors in Africa, rainfall may be a poor guide to predicting the timing of peaks in An. stephensi-driven malaria transmission. This highlights the urgent need for longitudinal entomological monitoring of the vector in its new environments given recent invasion and potential spread across the continent.

The retromer complex regulates C. elegans development and mammalian ciliogenesis.

The mammalian retromer consists of subunits VPS26 (either VPS26A or VPS26B), VPS29 and VPS35, and a loosely associated sorting nexin (SNX) heterodimer or a variety of other SNX proteins. Despite involvement in yeast and mammalian cell trafficking, the role of retromer in development is poorly understood, and its impact on primary ciliogenesis remains unknown. Using CRISPR/Cas9 editing, we demonstrate that vps-26-knockout worms have reduced brood sizes, impaired vulval development and decreased body length, all of which have been linked to ciliogenesis defects. Although preliminary studies did not identify worm ciliary defects, and impaired development limited additional ciliogenesis studies, we turned to mammalian cells to investigate the role of retromer in ciliogenesis. VPS35 localized to the primary cilium of mammalian cells, and depletion of VPS26, VPS35, VPS29, SNX1, SNX2, SNX5 or SNX27 led to decreased ciliogenesis. Retromer also coimmunoprecipitated with the centriolar protein, CP110 (also known as CCP110), and was required for its removal from the mother centriole. Herein, we characterize new roles for retromer in C. elegans development and in the regulation of ciliogenesis in mammalian cells, suggesting a novel role for retromer in CP110 removal from the mother centriole.

Genotypic variation in the promoter region of the CRH-248 gene interacts with early rearing experiences to disrupt the development of the HPA axis in infant rhesus macaques (Macaca mulatta).

Aberrant functioning of the hypothalamic-pituitary-adrenal (HPA) axis is a hallmark of conditions such as depression, anxiety disorders, and post-traumatic stress disorder. Early-life adversity and genetic variation can interaction to disrupt HPA axis regulation, potentially contributing to certain forms of psychopathology. This study employs a rhesus macaque model to investigate how early parental neglect interacts with a single nucleotide polymorphism within the promoter region of the corticotropin-releasing hormone (CRH-248) gene, impacting the development of the HPA axis. For the initial six months of life, 307 rhesus monkey infants (n = 146 females, n = 161 males) were either reared with their mothers (MR) in conditions emulating the natural environment (control group) or raised without maternal care in groups with constant or 3-hours daily access to same-aged peers (NR). Blood samples collected on days 30, 60, 90, and 120 of life under stressful conditions were assayed for plasma cortisol and adrenocorticotropic hormone (ACTH) concentrations. Findings revealed that NR subjects exhibited a significant blunting of both ACTH and cortisol concentrations. Notably, there was a gene-by-environment interaction observed for ACTH and cortisol levels, with NR subjects with the polymorphism displaying higher ACTH concentrations and lower cortisol concentrations. To the extent that these results generalize to humans, they suggest that early parental neglect may render individuals vulnerable to HPA axis dysfunction, a susceptibility that is modulated by CRH-248 genotype-a gene-by-environment interaction that leaves a lasting developmental signature.

LLIN Evaluation in Uganda Project (LLINEUP): modelling the impact of COVID-19-related disruptions on delivery of long-lasting insecticidal nets on malaria indicators in Uganda.

BACKGROUND: Disruptions in malaria control due to COVID-19 mitigation measures were predicted to increase malaria morbidity and mortality in Africa substantially. In Uganda, long-lasting insecticidal nets (LLINs) are distributed nationwide every 3-4 years, but the 2020-2021 campaign was altered because of COVID-19 restrictions so that the timing of delivery of new nets was different from the original plans made by the National Malaria Control Programme. METHODS: A transmission dynamics modelling exercise was conducted to explore how the altered delivery of LLINs in 2020-2021 impacted malaria burden in Uganda. Data were available on the planned LLIN distribution schedule for 2020-2021, and the actual delivery. The transmission model was used to simulate 100 health sub-districts, and parameterized to match understanding of local mosquito bionomics, net use estimates, and seasonal patterns based on data collected in 2017-2019 during a cluster-randomized trial (LLINEUP). Two scenarios were compared; simulated LLIN distributions matching the actual delivery schedule, and a comparable scenario simulating LLIN distributions as originally planned. Model parameters were otherwise matched between simulations. RESULTS: Approximately 70% of the study population received LLINs later than scheduled in 2020-2021, although some areas received LLINs earlier than planned. The model indicates that malaria incidence in 2020 was substantially higher in areas that received LLINs late. In some areas, early distribution of LLINs appeared less effective than the original distribution schedule, possibly due to attrition of LLINs prior to transmission peaks, and waning LLIN efficacy after distribution. On average, the model simulations predicted broadly similar overall mean malaria incidence in 2021 and 2022. After accounting for differences in cluster population size and LLIN distribution dates, no substantial increase in malaria burden was detected. CONCLUSIONS: The model results suggest that the disruptions in the 2020-2021 LLIN distribution campaign in Uganda did not substantially increase malaria burden in the study areas.

Feasibility of Mindful After Cancer: Pilot Study of a Virtual Mindfulness-Based Intervention for Sexual Health in Cancer Survivorship.

BACKGROUND: Mindfulness-based interventions (MBIs) are increasingly recognized as an effective strategy for supporting female cancer survivors experiencing sexual health concerns. AIM: To examine the feasibility of a sexual health MBI, Mindful After Cancer, which was adapted to meet the needs of breast and gynecologic cancer survivors in a community setting and for delivery via videoconference. METHODS: A mixed-methods approach was used to evaluate the acceptability, feasibility, and appropriateness of the 8-week virtual MBI. Weekly sessions were 1.5-2 hours in duration and included guided meditations and group discussion about sexuality after cancer and mindfulness in daily life. Home practice activities related to both mindfulness practice and sexual health. Participants completed online surveys at baseline and 1-month post-intervention. A purposive sample of 10 participants were invited to complete a follow-up interview 2-3 months post-intervention. OUTCOMES: Primary outcomes included both qualitative and quantitative assessments of acceptability, appropriateness, and feasibility of the Mindful After Cancer intervention for sexual health in cancer survivorship. RESULTS: Twenty-two women completed the intervention (Mean age 53.2 years, SD = 9.4, Range= 39-73), with time since diagnosis ranging from 1 to 27 years (Mean 6.0 years, SD = 5.9). Participants completed 6.8 sessions on average (Range = 2 - 8) and 77% reported that the time commitment was manageable. Both qualitative and quantitative findings support the feasibility, acceptability, and appropriateness of the intervention. CLINICAL IMPLICATIONS: Many cancer survivors experience sexual dysfunction and related distress after diagnosis and well after treatment ends, yet there are few interventions available. Improved access to effective interventions can improve the delivery of survivorship care and patient outcomes. STRENGTHS & LIMITATIONS: The sample size is small for this pilot study, and a control group was not included. The intervention was offered over two time periods, one prior to COVID-19 pandemic and one during the pandemic, resulting in both limitations associated with potential differences between the experiences of participants and the opportunity to learn more about the feasibility of the intervention during times of crisis. CONCLUSION: Results suggest that virtual delivery of the MBI is feasible, acceptable, and appropriate for breast and gynecologic cancer survivors. Gorman JR, Drizin JH, Smith E, et al.

Durability of three types of dual active ingredient long-lasting insecticidal net compared to a pyrethroid-only LLIN in Tanzania: methodology for a prospective cohort study nested in a cluster randomized controlled trial.

BACKGROUND: Progress achieved by long-lasting insecticidal nets (LLINs) against malaria is threatened by widespread selection of pyrethroid resistance among vector populations. LLINs with non-pyrethroid insecticides are urgently needed. This study aims to assess the insecticide and textile durability of three classes of dual-active ingredient (A.I.) LLINs using techniques derived from established WHO LLIN testing methods to set new standards of evaluation. METHODS: A WHO Phase 3 active ingredients and textile durability study will be carried out within a cluster randomized controlled trial in 40 clusters in Misungwi district, Tanzania. The following treatments will be evaluated: (1) Interceptor®G2 combining chlorfenapyr and the pyrethroid alpha-cypermethrin, (2) Royal Guard® treated with pyriproxyfen and alpha-cypermethrin, (3) Olyset™ Plus which incorporates a synergist piperonyl butoxide and the pyrethroid permethrin, and (4) a reference standard alpha-cypermethrin only LLIN (Interceptor®). 750 nets will be followed in 5 clusters per intervention arm at 6, 12, 24 and 36 months post distribution for survivorship and hole index assessment. A second cohort of 1950 nets per net type will be identified in 10 clusters, of which 30 LLINs will be withdrawn for bio-efficacy and chemical analysis every 6 months up to 36 months and another 30 collected for experimental hut trials every year. Bio-efficacy will be assessed using cone bioassays and tunnel tests against susceptible and resistant laboratory strains of Anopheles gambiae sensu stricto. Efficacy of field-collected nets will be compared in six experimental huts. The main outcomes will be Anopheles mortality up to 72 h post exposure, blood feeding and egg maturation using ovary dissection to assess impact on fecundity. CONCLUSIONS: Study findings will help develop bio-efficacy and physical durability criteria for partner A.I., in relation to the cRCT epidemiological and entomological outcomes, and refine preferred product characteristics of each class of LLIN. If suitable, the bioassay and hut outcomes will be fitted to transmission models to estimate correlation with cRCT outcomes. TRIAL REGISTRATION NUMBER: NCT03554616.

Design and methods for a quasi-experimental pilot study to evaluate the impact of dual active ingredient insecticide-treated nets on malaria burden in five regions in sub-Saharan Africa.

BACKGROUND: Vector control tools have contributed significantly to a reduction in malaria burden since 2000, primarily through insecticidal-treated bed nets (ITNs) and indoor residual spraying. In the face of increasing insecticide resistance in key malaria vector species, global progress in malaria control has stalled. Innovative tools, such as dual active ingredient (dual-AI) ITNs that are effective at killing insecticide-resistant mosquitoes have recently been introduced. However, large-scale uptake has been slow for several reasons, including higher costs and limited evidence on their incremental effectiveness and cost-effectiveness. The present report describes the design of several observational studies aimed to determine the effectiveness and cost-effectiveness of dual-AI ITNs, compared to standard pyrethroid-only ITNs, at reducing malaria transmission across a variety of transmission settings. METHODS: Observational pilot studies are ongoing in Burkina Faso, Mozambique, Nigeria, and Rwanda, leveraging dual-AI ITN rollouts nested within the 2019 and 2020 mass distribution campaigns in each country. Enhanced surveillance occurring in select study districts include annual cross-sectional surveys during peak transmission seasons, monthly entomological surveillance, passive case detection using routine health facility surveillance systems, and studies on human behaviour and ITN use patterns. Data will compare changes in malaria transmission and disease burden in districts receiving dual-AI ITNs to similar districts receiving standard pyrethroid-only ITNs over three years. The costs of net distribution will be calculated using the provider perspective including financial and economic costs, and a cost-effectiveness analysis will assess incremental cost-effectiveness ratios for Interceptor® G2, Royal Guard®, and piperonyl butoxide ITNs in comparison to standard pyrethroid-only ITNs, based on incidence rate ratios calculated from routine data. CONCLUSIONS: Evidence of the effectiveness and cost-effectiveness of the dual-AI ITNs from these pilot studies will complement evidence from two contemporary cluster randomized control trials, one in Benin and one in Tanzania, to provide key information to malaria control programmes, policymakers, and donors to help guide decision-making and planning for local malaria control and elimination strategies. Understanding the breadth of contexts where these dual-AI ITNs are most effective and collecting robust information on factors influencing comparative effectiveness could improve uptake and availability and help maximize their impact.

Mosquito feeding behavior and how it influences residual malaria transmission across Africa.

The antimalarial efficacy of the most important vector control interventions-long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS)-primarily protect against mosquitoes' biting people when they are in bed and indoors. Mosquito bites taken outside of these times contribute to residual transmission which determines the maximum effectiveness of current malaria prevention. The likelihood mosquitoes feed outside the time of day when LLINs and IRS can protect people is poorly understood, and the proportion of bites received outdoors may be higher after prolonged vector control. A systematic review of mosquito and human behavior is used to quantify and estimate the public health impact of outdoor biting across Africa. On average 79% of bites by the major malaria vectors occur during the time when people are in bed. This estimate is substantially lower than previous predictions, with results suggesting a nearly 10% lower proportion of bites taken at the time when people are beneath LLINs since the year 2000. Across Africa, this higher outdoor transmission is predicted to result in an estimated 10.6 million additional malaria cases annually if universal LLIN and IRS coverage was achieved. Higher outdoor biting diminishes the cases of malaria averted by vector control. This reduction in LLIN effectiveness appears to be exacerbated in areas where mosquito populations are resistant to insecticides used in bed nets, but no association was found between physiological resistance and outdoor biting. Substantial spatial heterogeneity in mosquito biting behavior between communities could contribute to differences in effectiveness of malaria control across Africa.

Dyadic support across contraceptive decision-making among young adult breast cancer survivors and their partners.

OBJECTIVE: The purpose of this study is to explore the role of dyadic support across the contraceptive decision-making process between young adult breast cancer (YABC) survivors and their partners. RESEARCH APPROACH: Semi-structured interviews with YABC survivors and their partners. PARTICIPANTS: Twenty-five young adult breast cancer survivors and their partners (n = 50). Survivors reported an average age of 36.9 years (SD = 4.30) and the majority self-identified as white (86.2%). METHODOLOGICAL APPROACH: Thematic analysis approach with dyads as the primary unit of analysis, guided by the dyadic decision-making framework and the Theory of Gender and Power. RESULTS: Perceived lack of contraceptive options due to a history of hormone-sensitive cancer, perceived infertility, and contraception as a result of cancer treatment (e.g., hysterectomy) contributed to the contraceptive decision context for survivors and their partners. Contraceptive support varied across couples depending on the cancer-specific context, where communication, sharing responsibility, and respecting bodily autonomy revealed as supportive behaviors. Other social influences including survivors' desire to conceive biologically and family planning desires also related to partner supportive behaviors. INTERPRETATIONS: YABC survivors face specific challenges to contraceptive decision-making where partners can offer supportive behaviors. Health care providers can also support couples by engaging in triadic communication about contraception and family planning. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS OR POLICY: Psychosocial providers can support couples by encouraging them to talk together about contraception and highlighting the importance of triadic communication with a healthcare provider to support shared decision-making and alignment of contraceptive decisions with family planning desires.

Using syndromic measures of mortality to capture the dynamics of COVID-19 in Java, Indonesia, in the context of vaccination rollout.

BACKGROUND: As in many countries, quantifying COVID-19 spread in Indonesia remains challenging due to testing limitations. In Java, non-pharmaceutical interventions (NPIs) were implemented throughout 2020. However, as a vaccination campaign launches, cases and deaths are rising across the island. METHODS: We used modelling to explore the extent to which data on burials in Jakarta using strict COVID-19 protocols (C19P) provide additional insight into the transmissibility of the disease, epidemic trajectory, and the impact of NPIs. We assess how implementation of NPIs in early 2021 will shape the epidemic during the period of likely vaccine rollout. RESULTS: C19P burial data in Jakarta suggest a death toll approximately 3.3 times higher than reported. Transmission estimates using these data suggest earlier, larger, and more sustained impact of NPIs. Measures to reduce sub-national spread, particularly during Ramadan, substantially mitigated spread to more vulnerable rural areas. Given current trajectory, daily cases and deaths are likely to increase in most regions as the vaccine is rolled out. Transmission may peak in early 2021 in Jakarta if current levels of control are maintained. However, relaxation of control measures is likely to lead to a subsequent resurgence in the absence of an effective vaccination campaign. CONCLUSIONS: Syndromic measures of mortality provide a more complete picture of COVID-19 severity upon which to base decision-making. The high potential impact of the vaccine in Java is attributable to reductions in transmission to date and dependent on these being maintained. Increases in control in the relatively short-term will likely yield large, synergistic increases in vaccine impact.

Quantifying individual variability in exposure risk to mosquito bites in the Cascades region, Burkina Faso.

BACKGROUND: The Cascades region, Burkina Faso, has a high malaria burden despite reported high insecticide-treated mosquito net (ITN) use. Human and vector activities outside the hours when indoor interventions offer direct protection from infectious bites potentially increase exposure risk to bites from malaria-transmitting Anopheles mosquitoes. This work investigated the degree of variation in human behaviour both between individuals and through time (season) to quantify how it impacts exposure to malaria vectors. METHODS: Patterns in human overnight activity (18:00-06:00) to quantify time spent using an ITN across 7 successive nights in two rural communities, Niakore (N = 24 participants) and Toma (71 participants), were observed in the dry and rainy seasons, between 2017 and 2018. Hourly human landing Anopheles mosquito catches were conducted in Niakore specifically, and Cascades region generally, between 2016 and 2017. Data were statistically combined to estimate seasonal variation in time spent outdoors and Anopheles bites received per person per night (bpppn). RESULTS: Substantial variability in exposure to outdoor Anopheles bites was detected within and between communities across seasons. In October, when Anopheles densities are highest, an individual's risk of Anopheles bites ranged from 2.2 to 52.2 bites per person per night (bpppn) within the same week with variable risk dependent on hours spent indoors. Comparably higher outdoor human activity was observed in April and July but, due to lower Anopheles densities estimated, bpppn were 0.2-4.7 and 0.5-32.0, respectively. Males and people aged over 21 years were predicted to receive more bites in both sentinel villages. CONCLUSION: This work presents one of the first clear descriptions of the degree of heterogeneity in time spent outdoors between people and across the year. Appreciation of sociodemographic, cultural and entomological activities will help refine approaches to vector control.

Patient-Centered Communication to Address Young Adult Breast Cancer Survivors' Reproductive and Sexual Health Concerns.

Women faced with a diagnosis of breast cancer as young adults commonly experience negative effects of cancer and cancer treatment on their reproductive and sexual health (RSH) that are inadequately addressed by their healthcare providers (HCPs). The objectives of this study were to 1) identify approaches to improving RSH communication from YA breast cancer survivors' perspectives, 2) identify facilitators and barriers to the approaches identified, and 3) identify specific strategies to improve patient-centered RSH communication. We conducted individual telephone interviews with 29 women who were diagnosed with breast cancer under age 40 years. We used a grounded theory approach to identify themes, and explored how the themes related to the PCC framework to elucidate specific strategies for improving communication. Three main themes emerged: 1) Normalizing and integrating assessment of RSH concerns; 2) HCP conveying genuine caring and investment; and 3) Improving accessibility of comprehensive RSH services after cancer. Results revealed concrete strategies for improving patient-centered RSH communication at the patient-provider and health system levels. These included reminding patients that RSH concerns are common, routinely asking about RSH, using active listening, and connecting patients to HCP who can address their RSH concerns.

Methods and indicators for measuring patterns of human exposure to malaria vectors.

BACKGROUND: Effective targeting and evaluation of interventions that protect against adult malaria vectors requires an understanding of how gaps in personal protection arise. An improved understanding of human and mosquito behaviour, and how they overlap in time and space, is critical to estimating the impact of insecticide-treated nets (ITNs) and determining when and where supplemental personal protection tools are needed. Methods for weighting estimates of human exposure to biting Anopheles mosquitoes according to where people spend their time were first developed over half a century ago. However, crude indoor and outdoor biting rates are still commonly interpreted as indicative of human-vector contact patterns without any adjustment for human behaviour or the personal protection effects of ITNs. MAIN TEXT: A small number of human behavioural variables capturing the distribution of human populations indoors and outdoors, whether they are awake or asleep, and if and when they use an ITN over the course of the night, can enable a more accurate representation of human biting exposure patterns. However, to date no clear guidance is available on what data should be collected, what indicators should be reported, or how they should be calculated. This article presents an integrated perspective on relevant indicators of human-vector interactions, the critical entomological and human behavioural data elements required to quantify human-vector interactions, and recommendations for collecting and analysing such data. CONCLUSIONS: If collected and used consistently, this information can contribute to an improved understanding of how malaria transmission persists in the context of current intervention tools, how exposure patterns may change as new vector control tools are introduced, and the potential impact and limitations of these tools. This article is intended to consolidate understanding around work on this topic to date and provide a consistent framework for building upon it. Additional work is needed to address remaining questions, including further development and validation of methods for entomological and human behavioural data collection and analysis.

Navigating sexual health in cancer survivorship: a dyadic perspective.

PURPOSE: This qualitative study examined how young adult breast cancer survivors (YABCS) and their partners appraised and managed their sexual health and intimate relationships after cancer. METHODS: We conducted concurrent, individual telephone interviews with 25 YABCS and their male partners. We utilized a thematic, inductive analysis to examine individual interviews, followed by analysis within and across couples to identify dyadic themes. We explored how themes mapped on to the Theory of Dyadic Illness Management to build a conceptual model specific to the sexual health challenges of young adult couples living with cancer. RESULTS: Our analysis revealed five interconnected themes: (1) shared understanding of physical and psychological challenges of sexual health after cancer, (2) navigating role shifts and changes to sexual relationship, (3) getting through it as a team, (4) maintaining open communication, and (5) need for services and support for partners/caregivers and couples. CONCLUSION: Both survivors and their partners articulated physical (e.g., painful sex, decreased libido) and psychological (e.g., guilt, self-consciousness) challenges to their sexual health in survivorship. Our dyadic focus revealed a spectrum of ways that couples managed the changes to their relationships and sexual health, highlighting "open communication" and strategies for "working as a team" as critical. There is no "one size fits all" solution, as individuals and couples cope with and manage these challenges in different ways. Study results can inform couple-focused intervention strategies, such as creating shared understanding of sexual health after cancer and improving communication skills.

Moving Oral Contraceptives over the Counter: Theory-based Formative Research to Design Communication Strategy.

The American College of Obstetricians and Gynecologists (ACOG) recommends that oral contraceptives (OC) should be available over the counter (OTC). This study explored women's attitudes toward OC OTC in rural South Carolina. In-depth, individual interviews were conducted with 52 women ages 18-44 years old. Data analysis was informed by a reproductive justice theoretical framework and included an inductive, constant-comparative approach using HyperRESEARCH 3.7.5. Participants self-identified as either Black (62%) or White (28%). Participants believed that OC OTC would prevent unintended pregnancy by improving anonymity, convenience, and access to contraception. Many participants faced barriers to receiving a prescription, including time, transportation, cost, stigma, embarrassment, and clinician refusal based on religious reasons. Participants believed OC OTC would improve women's control over their fertility and emphasized the importance of health insurance coverage for OC OTC. Some participants expressed concerns about the risk of side effects, contraindications, and the potential for abuse. Some participants believed women, especially adolescents, required physician guidance and an annual exam to use OC. Findings suggest that a lack of knowledge and misinformation about the risks of OC serve as a barrier among some women in rural areas. Widespread acceptance of OC OTC will require messaging strategies to dispel safety concerns about OC OTC and empower women.

"People are struggling in this area:" a qualitative study of women's perspectives of telehealth in rural South Carolina.

Rural communities face disparities and barriers to health care access that may be addressed through telehealth programs; yet little research is available detailing rural women's attitudes toward telehealth. Researchers partnered with a women's reproductive health organization to conduct formative audience research to understand rural women's perspectives of telehealth in their communities. Qualitative research was conducted to improve understandings of women's perceptions of telehealth in rural South Carolina. In-depth interviews with 52 women aged 18-44 years were conducted in five rural counties in South Carolina during June - August 2015. Analytical techniques from grounded theory methodology were used throughout data collection and analysis. Participants believed a telehealth intervention would benefit the community by addressing reproductive health barriers, such as cost, transportation, and long wait times at local health care facilities. Participants' concerns included issues of confidentiality in a small town, discomfort with mediated communication, privacy, and the importance of relationship-centered care, including patient-provider communication and approachability of health care providers. Findings provide insight to design and implement telehealth interventions to improve women's health in rural communities.

Evaluating the Whoops Proof S.C. Campaign: A Pair-Matched Group Pretest-Posttest Quasi-experimental Study.

INTRODUCTION: In South Carolina, 50% of all pregnancies are unintended. Intrauterine devices (IUDs) and the implant are recommended as top-tier contraceptive options for all women and adolescents. The Whoops Proof S.C. campaign was evaluated to determine if women (ages 18 to 29) who do not intend to become pregnant in the next year report greater awareness of and positive regard for IUDs and the implant after exposure to a multi-channel campaign. METHODS: A pair-matched group pretest-posttest quasi-experimental design was utilized. A total of 1,439 women responded to the pretest survey (May-July 2016) and 1,534 responded to the posttest survey (October-November 2016) in four South Carolina counties. Statistical analysis include paired-sample and independent t-tests and one-way ANOVA tests for variance. RESULTS: At posttest, intervention county participants were significantly more likely to recall messaging and to report receiving contraceptive information from Whoops Proof S.C (t(1533)= - 8.466, p < .0001). Participants who saw ads more than once per week reported a significant increase in awareness of IUDs and the implant (F(6,1532) = 5.571; p < .001). Participants in intervention counties reported a significant increase in positive attitudes toward IUDs (t(616) = - 1.740; p = .041) and the implant (t(603)= - 1.665; p = .048). DISCUSSION: The Whoops Proof S.C. campaign offers strategies to campaign planners and health care providers to optimize exposure and recall frequency to increase awareness of and positive regard for highly effective contraceptive methods. Campaign planners should test messages and focus on communication channels to increase engagement and avoid saturation.

An inexpensive open source 3D-printed membrane feeder for human malaria transmission studies.

BACKGROUND: The study of malaria transmission requires the experimental infection of mosquitoes with Plasmodium gametocytes. In the laboratory, this is achieved using artificial membrane feeding apparatus that simulate body temperature and skin of the host, and so permit mosquito feeding on reconstituted gametocyte-containing blood. Membrane feeders either use electric heating elements or complex glass chambers to warm the infected blood; both of which are expensive to purchase and can only be sourced from a handful of specialized companies. Presented and tested here is a membrane feeder that can be inexpensively printed using 3D-printing technology. RESULTS: Using the Plasmodium falciparum laboratory strain NF54, three independent standard membrane feeding assays (SMFAs) were performed comparing the 3D-printed feeder against a commercial glass feeder. Exflagellation rates did not differ between the two feeders. Furthermore, no statistically significant difference was found in the oocyst load nor oocyst intensity of Anopheles stephensi mosquitoes (mean oocyst range 1.3-6.2 per mosquito; infection prevalence range 41-79%). CONCLUSIONS: Open source provision of the design files of the 3D-printed feeder will facilitate a wider range of laboratories to perform SMFAs in laboratory and field settings, and enable them to freely customize the design to their own requirements.
