RESUMO

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).

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Despite their increased enrollment into medical school, women still face systemic barriers in medicine, whether in an academic or nonacademic setting. Those from Under-Represented Minority (URM) groups face similar issues, which may affect their desire to enter, pursue, and/or maintain a career in medicine. Social media provides unique opportunities for peer-to-peer support among members of URM communities and for amplification of their voices calling for social justice-here defined as a redistribution of power and the quest for equity in access to opportunities, including access to mentorship, professional development, and timely promotion in academic rank. These issues are relevant to oncologists especially as we strive for diversity, equity, and inclusion and to ensure that our patients have equal access to care, regardless of their circumstances. In this article, we review current literature that highlights issues faced by women and historically URM groups in medicine, particularly in oncology. We also discuss the physician's role as a social justice advocate and the concept of the public physician.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Expert knowledge is often shared among multidisciplinary academic teams at tumor boards (TBs) across the country, but these conversations exist in silos and do not reach the wider oncology community. OBJECTIVE: Using an oncologist-only question and answer (Q&A) website, we sought to document expert insights from TBs at National Cancer Institute-designated Comprehensive Cancer Centers (NCI-CCCs) to provide educational benefits to the oncology community. METHODS: We designed a process with the NCI-CCCs to document and share discussions from the TBs focused on areas of practice variation on theMednet, an interactive Q&A website of over 13,000 US oncologists. The faculty translated the TB discussions into concise, non-case-based Q&As on theMednet. Answers were peer reviewed and disseminated in email newsletters to registered oncologists. Reach and engagement were measured. Following each Q&A, a survey question asked how the TB Q&As impacted the readers' practice. RESULTS: A total of 23 breast, thoracic, gastrointestinal, and genitourinary programs from 16 NCI-CCC sites participated. Between December 2016 and July 2021, the faculty highlighted 368 questions from their TBs. Q&As were viewed 147,661 times by 7381 oncologists at 3515 institutions from all 50 states. A total of 277 (75%) Q&As were viewed every month. Of the 1063 responses to a survey question on how the Q&A affected clinicians' practices, 646 (61%) reported that it confirmed their current practice, 163 (20%) indicated that a Q&A would change their future practice, and 214 (15%) reported learning something new. CONCLUSIONS: Through an online Q&A platform, academics at the NCI-CCCs share knowledge outside the walls of academia with oncologists across the United States. Access to up-to-date expert knowledge can reassure clinicians' practices, significantly impact patient care in community practices, and be a source of new knowledge and education.

RESUMO

The use of social media continues to increase in health care and academia. Health care practice, particularly the oncologic field, is constantly changing because of new knowledge, evidence-based research, clinical trials, and government policies. Therefore, oncology trainees and professionals continue to strive to stay up-to-date with practice guidelines, research, and skills. Although social media as an educational and professional development tool is no longer completely new to medicine and has been embraced, it is still under-researched in terms of various outcomes. Social media plays several key roles in professional development and academic advancement. We reviewed the literature to evaluate how social media can be used for professional development and academic promotion of oncology professionals.

RESUMO

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).

RESUMO

PURPOSE: The COVID-19 pandemic led to unprecedented challenges in medical training, and we sought to assess the specific impact of COVID-19 on hematology-oncology (HO) fellowship programs. METHODS: We conducted a cross-sectional anonymous online survey of 103 HO program directors (PDs) in conjunction with the American Society of Hematology (ASH) and ASCO. We sought to assess the specific impact of COVID-19 on HO fellowship programs' clinical, educational, and research activities, evaluate perceptions regarding PD and trainee emotional and mental health, and identify ways to support programs. Data were analyzed using descriptive statistics, parametric and nonparametric tests, and multivariable logistic regression models. Responses to open-ended questions were analyzed with thematic analysis. RESULTS: Significant changes to fellowship activities included transitioning fellow training from outpatient clinics to telehealth (77.7%), shifting to virtual education (94.2%), and moving to remote research work (63.1%). A minority (21.4%) of PDs reported that their fellows were redeployed to cover non-HO services. Most PDs (54.4%) believed COVID-19 had a slight negative impact on fellowship training. PD self-reported burnout increased significantly from 15.5% prepandemic to 44.7% during the pandemic, and most PDs witnessed minor signs of fellow burnout (52.4%). Common PD concerns included inadequate supervision for telehealth activities, reduced opportunities for fellow advancement and promotion, lack of professional development activities, limited research operations and funding, program financial constraints, and virtual recruitment. CONCLUSION: We encourage institutions and national societies to allocate resources and develop programs that can support fellowships and mitigate the potential negative effects of COVID-19 on trainee and PD career development.

RESUMO

PURPOSE: Graduate medical and research training has drastically changed during the COVID-19 pandemic, with widespread implementation of virtual learning, redeployment from core rotations to the care of patients with COVID-19, and significant emotional and physical stressors. The specific experience of hematology-oncology (HO) fellows during the COVID-19 pandemic is not known. METHODS: We conducted a mixed-methods study using a survey of Likert-style and open-ended questions to assess the training experience and well-being of HO fellows, including both clinical and postdoctoral trainee members of the American Society of Hematology and ASCO. RESULTS: A total of 2,306 surveys were distributed by e-mail; 548 (23.8%) fellows completed the survey. Nearly 40% of fellows felt that they had not received adequate mental health support during the pandemic, and 22% reported new symptoms of burnout. Pre-existing burnout before the pandemic, COVID-19-related clinical work, and working in a primary research or nonclinical setting were associated with increased burnout on multivariable logistic regression. Qualitative thematic analysis of open-ended responses revealed significant concerns about employment after training completion, perceived variable quality of virtual education and board preparation, loss of clinical opportunities to prepare for independent clinical practice, inadequate grant funding opportunities in part because of shifting research priorities, variable productivity, and mental health or stress during the pandemic. CONCLUSION: HO fellows have been profoundly affected by the pandemic, and our data illustrate multiple avenues for fellowship programs and national organizations to support both clinical and postdoctoral trainees.

RESUMO

PURPOSE: COVID-19 challenged medical practice and graduate medical education. Building on previous initiatives, we describe and reflect on the formative process and goals of the Hematology-Oncology Collaborative Videoconferencing Learning Initiative, a trainee-led multi-institutional virtual COVID-19 learning model. METHODS: Clinical fellows and faculty from 13 US training institutions developed consensus needs, goals, and objectives, recruited presenters, and generated a multidisciplinary COVID-19 curriculum. Weekly Zoom conferences consisted of two trainee-led instructional segments and a trainee-moderated faculty Q&A panel. Hematology-oncology training program faculty and trainees were the targeted audience. Leadership evaluations consisted of anonymized baseline and concluding mixed methods surveys. Presenter evaluations consisted of session debriefs and two structured focus groups. Conference evaluations consisted of attendance, demographics, and pre- or postmultiple-choice questions on topic learning objectives. RESULTS: In 6 weeks, the initiative produced five conferences: antivirals, anticoagulation, pulmonology, provider resilience, and resource scarcity ethics. The average attendance was 100 (range 57-185). Among attendees providing both pre- and postconference data, group-level knowledge appeared to increase: antiviral (n = 46) pre-/postcorrect 82.6%/97.8% and incorrect 10.9%/2.2%, anticoagulation (n = 60) pre-/postcorrect 75%/93.3% and incorrect 15%/6.7%, and pulmonary (n = 21) pre-/postcorrect 66.7%/95.2% and incorrect 33.3%/4.8%. Although pulmonary management comfort appeared to increase, comfort managing of antivirals and anticoagulation was unchanged. At the conclusion of the pilot, leadership trainees reported improved self-confidence organizing multi-institutional collaborations, median (interquartile range) 58.5 (50-64) compared with baseline 34 (26-39), but did not report improved confidence in other educational or leadership skills. CONCLUSION: During crisis, trainees built a multi-institutional virtual education platform for the purposes of sharing pandemic experiences and knowledge. Accomplishment of initiative goals was mixed. Lessons learned from the process and goals may improve future disaster educational initiatives.

RESUMO

INTRODUCTION: Maternity waiting homes (MWHs) aim to increase access to maternity and emergency obstetric care by allowing women to stay near a health centre before delivery. An improved MWH model was developed with community input and included infrastructure, policies and linkages to health centres. We hypothesised this MWH model would increase health facility delivery among remote-living women in Zambia. METHODS: We conducted a quasi-experimental study at 40 rural health centres (RHC) that offer basic emergency obstetric care and had no recent stockouts of oxytocin or magnesium sulfate, located within 2 hours of a referral hospital. Intervention clusters (n=20) received an improved MWH model. Control clusters (n=20) implemented standard of care. Clusters were assigned to study arm using a matched-pair randomisation procedure (n=20) or non-randomly with matching criteria (n=20). We interviewed repeated cross-sectional random samples of women in villages 10+ kilometres from their RHC. The primary outcome was facility delivery; secondary outcomes included postnatal care utilisation, counselling, services received and expenditures. Intention-to-treat analysis was conducted. Generalised estimating equations were used to estimate ORs. RESULTS: We interviewed 2381 women at baseline (March 2016) and 2330 at endline (October 2018). The improved MWH model was associated with increased odds of facility delivery (OR 1.60 (95% CI: 1.13 to 2.27); p<0.001) and MWH utilisation (OR 2.44 (1.62 to 3.67); p<0.001). The intervention was also associated with increased odds of postnatal attendance (OR 1.55 (1.10 to 2.19); p<0.001); counselling for family planning (OR 1.48 (1.15 to 1.91); p=0.002), breast feeding (OR 1.51 (1.20 to 1.90); p<0.001), and kangaroo care (OR 1.44 (1.15, 1.79); p=0.001); and caesarean section (OR 1.71 (1.16 to 2.54); p=0.007). No differences were observed in household expenditures for delivery. CONCLUSION: MWHs near well-equipped RHCs increased access to facility delivery, encouraged use of facilities with emergency care capacity, and improved exposure to counselling. MWHs can be useful in the effort to increase delivery at advanced facilities in areas where substantial numbers of women live remotely. TRIAL REGISTRATION NUMBER: NCT02620436.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: This paper provides estimates of contraceptive discontinuation and failure rates in a poor urban setting in Ghana. Contraceptive use is for the purposes of preventing unintended or mistimed pregnancies. Unfortunately, evidence abounds in many parts of the world where there is considerable levels of contraceptive failure and high levels of discontinuation resulting in unintended pregnancies. METHODS: We estimated discontinuation rates during a 12-month period since starting use by applying single and multiple decrement life table methods to the contraceptive calendar data collected in a survey of women in reproductive age of 15-49 years. RESULTS: Modern contraceptive method use was estimated to be 13.7% at the time of the survey. The results show that contraceptive method discontinuation vary markedly by type of contraceptive method but are high for almost all methods, except for implants (23.7%). Discontinuation rate for emergency contraception was estimated at 88.5%, withdrawal 87.6%, and male condom use 80.9%. However, discontinuation rates were moderately high for rhythm (63.6%), pills (65.6%) and injectables (56%). In terms of failure rates, overall contraceptive failure for all methods was estimated at 7.9%. The factors significantly associated with method failure include being within age bracket 40-44 years (OR = 0.3, p < 0.05), having secondary/higher education (OR = 0.4, p < 0.01), belonging to the richest household wealth scale (OR = 3.3, p < 0.01), currently in union with a partner (OR = 2.2, p < 0.01), and using contraceptive methods such as rhythm (OR = 5.6, p < 0.01) and withdrawal (OR = 3.7, p < 0.01). On the flip side, the odds for method discontinuation were significantly higher for women in their 20s and mid 30s, formerly in union (OR = 1.9, p < 0.05) and use of withdrawal method (OR = 1.4, p < 0.05) and lower for women formerly in union (OR = 0.4, p < 0.01) and use of implants (OR = 0.2, p < 0.01) and injectables (OR = 0.6, p < 0.01). CONCLUSION: While contraceptives use is low, both discontinuation and failure rates are high and variable among different methods. Failure and discontinuation rates are lowest for long-acting methods such as implants while higher failure rates are more prevalent among women who rely on withdrawal and the rhythm methods.

RESUMO

INTRODUCTION: Secondary cardiac malignancies are much more common than primary cancers. Metastatic cancers to the heart from other solid organs are well known and carry a poor prognosis. CASE PRESENTATION: An 83-year-old Hispanic veteran presented with breathlessness, cough, and weight loss. Imaging studies showed extensive pericardial effusion and multiple pericardial/epicardial masses. Biopsy showed poorly differentiated metastatic carcinoma with no definitive origin, based on lab, imaging, and extensive immunohistochemistry (IHC) studies. Gene panel testing showed microsatellite stable status. Programmed cell death 1 ligand (PD-L1) IHC was 100% in the tumor cells. He was started on pembrolizumab and had a complete resolution of symptoms. Subsequent imaging studies showed improvement in the multiple pericardial/epicardial masses. DISCUSSION: Immune checkpoint inhibitor (ICI) therapy has changed the treatment landscape of many malignancies since the approval of the first ICI, ipilimumab, for melanoma in 2011. To the best of our knowledge, this is the first reported case of successful treatment by ICI therapy in undifferentiated metastatic carcinoma of an unknown primary source to the heart.

RESUMO

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.
