RESUMEN

Sea-level rise is a significant indicator of broader climate changes, and the time of emergence concept can be used to identify when modern rates of sea-level rise emerged above background variability. Yet a range of estimates of the timing persists both globally and regionally. Here, we use a global database of proxy sea-level records of the Common Era (0-2000 CE) and show that globally, it is very likely that rates of sea-level rise emerged above pre-industrial rates by 1863 CE (P = 0.9; range of 1825 [P = 0.66] to 1873 CE [P = 0.95]), which is similar in timing to evidence for early ocean warming and glacier melt. The time of emergence in the North Atlantic reveals a distinct spatial pattern, appearing earliest in the mid-Atlantic region (1872-1894 CE) and later in Canada and Europe (1930-1964 CE). Regional and local sea-level changes occurring over different time periods drive the spatial pattern in emergence, suggesting regional processes underlie centennial-timescale sea-level variability over the Common Era.

RESUMEN

OBJECTIVES: The objective of this study was to determine bleeding control interventions (BCIs) that were reported to be effective in controlling postoperative bleeding in patients with inherited functional platelet disorders (IFPDs) undergoing invasive dental procedures. STUDY DESIGN: We searched MEDLINE/PubMed, Embase, Cochrane Library (Wiley), and Scopus from 1960 through April 2020 for studies on patients with IFPD undergoing invasive dental procedures. Two reviewers conducted assessments independently. RESULTS: We found a total of 620 nonduplicate published articles, of which 32 studies met our inclusion criteria. Management with BCI in patients with IFPD included in this systematic review was effective in 80.7% of treatment sessions. Local measures used intraoperatively were found to be effective. Three different protocols of BCI were noted; the most effective protocol consisted of antifibrinolytics, scaffold/matrix agents, and sutures (P < .01). An adjunct protocol consisting of a tissue sealant was also effective (P < .01). A third protocol of platelet transfusion and antifibrinolytics was ineffective in controlling postoperative bleeding in 4 of 6 dental sessions. CONCLUSIONS: This systematic review supports the use of local measures intraoperatively and antifibrinolytics postoperatively. It also supports making decision regarding platelet transfusion based on the clinician's clinical judgment and medical history of the individual patient.

RESUMEN

Sea-level budgets account for the contributions of processes driving sea-level change, but are predominantly focused on global-mean sea level and limited to the 20th and 21st centuries. Here we estimate site-specific sea-level budgets along the U.S. Atlantic coast during the Common Era (0-2000 CE) by separating relative sea-level (RSL) records into process-related signals on different spatial scales. Regional-scale, temporally linear processes driven by glacial isostatic adjustment dominate RSL change and exhibit a spatial gradient, with fastest rates of rise in southern New Jersey (1.6 ± 0.02 mm yr-1). Regional and local, temporally non-linear processes, such as ocean/atmosphere dynamics and groundwater withdrawal, contributed between -0.3 and 0.4 mm yr-1 over centennial timescales. The most significant change in the budgets is the increasing influence of the common global signal due to ice melt and thermal expansion since 1800 CE, which became a dominant contributor to RSL with a 20th century rate of 1.3 ± 0.1 mm yr-1.

RESUMEN

BACKGROUND: Most people around the world do not have access to facility-based diagnostic testing, and the gap in availability of diagnostic tests is a major public health challenge. Self-testing, self-sampling, and institutional testing outside conventional clinical settings are transforming infectious disease diagnostic testing in a wide range of low- and middle-income countries (LMICs). We examined the delivery models of infectious disease diagnostic testing outside clinics to assess the impact on test uptake and linkage to care. METHODS: We conducted a systematic review and meta-analysis, searching 6 databases and including original research manuscripts comparing testing outside clinics with conventional testing. The main outcomes were test uptake and linkage to care, delivery models, and adverse outcomes. Data from studies with similar interventions and outcomes within thematic areas of interest were pooled, and the quality of evidence was assessed using GRADE. This study was registered in PROSPERO (CRD42019140828).We identified 10 386 de-duplicated citations, and 76 studies were included. Data from 18 studies were pooled in meta-analyses. Studies focused on HIV (48 studies), chlamydia (8 studies), and multiple diseases (20 studies). HIV self-testing increased test uptake compared with facility-based testing (9 studies: pooled odds ratio [OR], 2.59; 95% CI, 1.06-6.29; moderate quality). Self-sampling for sexually transmitted infections increased test uptake compared with facility-based testing (7 studies: pooled OR, 1.74; 95% CI, 0.97-3.12; moderate quality). Conclusions. Testing outside of clinics increased test uptake without significant adverse outcomes. These testing approaches provide an opportunity to expand access and empower patients. Further implementation research, scale-up of effective service delivery models, and policies in LMIC settings are needed.

RESUMEN

BACKGROUND: Cancer is the leading cause of death among Hispanics/Latinos. Thus, understanding health-related quality of life (HRQOL) needs among this diverse racial/ethnic group is critical. Using Ferrell's multidimensional framework for measuring QOL, we synthesized evidence on HRQOL needs among Hispanic/Latino cancer survivors. METHODS: We searched MEDLINE/PubMed, EMBASE, CINAHL, and PsycINFO, for English language articles published between 1995 and January 2020, reporting HRQOL among Hispanic/Latino cancer survivors in the USA. RESULTS: Of the 648 articles reviewed, 176 met inclusion criteria, with 100 of these studies focusing exclusively on breast cancer patients and no studies examining end-of-life HRQOL issues. Compared with other racial/ethnic groups, Hispanics/Latinos reported lower HRQOL and a higher symptom burden across multiple HRQOL domains. Over 80% of studies examining racial/ethnic differences in psychological well-being (n = 45) reported worse outcomes among Hispanics/Latinos compared with other racial/ethnic groups. Hispanic/Latino cancer survivors were also more likely to report suboptimal physical well-being in 60% of studies assessing racial/ethnic differences (n = 27), and Hispanics/Latinos also reported lower social well-being relative to non-Hispanics/Latinos in 78% of studies reporting these outcomes (n = 32). In contrast, reports of spiritual well-being and spirituality-based coping were higher among Hispanics/Latinos cancer survivors in 50% of studies examining racial/ethnic differences (n = 15). DISCUSSION: Findings from this review point to the need for more systematic and tailored interventions to address HRQOL needs among this growing cancer survivor population. Future HRQOL research on Hispanics/Latinos should evaluate variations in HRQOL needs across cancer types and Hispanic/Latino subgroups and assess HRQOL needs during metastatic and end-of-life disease phases.

RESUMEN

BACKGROUND: Underrepresented minority (URM) cancer survivors experience disparities in mortality and quality of life, compared with non-Hispanic whites. Disparities are associated with poor social determinants of health, enhanced by mistrust of the healthcare system. Trust can be facilitated by provider-patient racial/ethnic concordance, yet URM survivors rarely experience concordance. Effective health communication is needed for this vulnerable population. OBJECTIVE: The aim of this study was to systematically review evidence on the composition and utility of health education videos among adult URM survivors. METHODS: Literature searches were conducted in Web of Science, Embase, PubMed, Cochrane, PsycInfo, and CINAHL databases. Articles that included adult URM cancer survivor samples and either described or tested a video intervention aimed to improve health outcomes were included. Two researchers independently screened articles for inclusion and quality appraisal and abstracted and synthesized relevant data to identify themes. RESULTS: Eight articles, detailing 7 independent studies, met inclusion criteria. Quality appraisal of the included studies was fair to good. Six themes were identified: (1) video development with stakeholders, (2) focus on designing culturally appropriate videos, (3) in-clinic video delivery, (4) video intervention effects, (5) provider and URM survivors support video interventions, and (6) building trust through personal stories. CONCLUSIONS: Video interventions are well received by URMs and improve outcomes yet are underutilized. More rigorous studies are warranted to develop best practices for video development and application. IMPLICATIONS FOR PRACTICE: Videos serve as an easy, effective tool to achieve favorable outcomes in the care of URM survivors.

RESUMEN

OBJECTIVES: A previous meta-analysis reported high HIV incidence among pregnant and breast-feeding women in sub-Saharan Africa (SSA), but limited evidence of elevated risk of HIV acquisition during pregnancy or breast-feeding when compared with nonpregnant periods. The rapidly evolving HIV prevention and treatment landscape since publication of this review may have important implications for maternal HIV incidence. DESIGN: Systematic review and meta-analysis. METHODS: We searched four databases and abstracts from relevant conferences through 1 December 2018, for literature on maternal HIV incidence in SSA. We used random-effects meta-analysis to summarize incidence rates and ratios, and to estimate 95% prediction intervals. We evaluated potential sources of heterogeneity with random-effects meta-regression. RESULTS: Thirty-seven publications contributed 100 758 person-years of follow-up. The estimated average HIV incidence rate among pregnant and breast-feeding women was 3.6 per 100 person-years (95% prediction interval: 1.2--11.1), while the estimated average associations between pregnancy and risk of HIV acquisition, and breast-feeding and risk of HIV acquisition, were close to the null. Wide 95% prediction intervals around summary estimates highlighted the variability of HIV incidence across populations of pregnant and breast-feeding women in SSA. Average HIV incidence appeared associated with age, partner HIV status, and calendar time. Average incidence was highest among studies conducted pre-2010 (4.1/100 person-years, 95% prediction interval: 1.1--12.2) and lowest among studies conducted post-2014 (2.1/100 person-years, 95% prediction interval: 0.7--6.5). CONCLUSION: Substantial HIV incidence among pregnant and breast-feeding women in SSA, even in the current era of combination HIV prevention and treatment, underscores the need for prevention tailored to high-risk pregnant and breast-feeding women.

RESUMEN

OBJECTIVE: We conducted meta-analyses and meta-analytic structural equation modeling of longitudinal studies among cancer survivors to (a) quantify associations between psychosocial predictors and physical activity, (b) test how psychosocial predictors combine to influence physical activity, and (c) identify study, demographic, and clinical characteristics that moderate associations. METHOD: Eligible studies used a longitudinal, observational design, included a sample of cancer survivors, and measured both a psychosocial predictor at baseline and physical activity at a later time-point. Of 2,431 records located through computerized searches, 25 independent tests (N = 5,897) met the inclusion criteria for the review. Random effects meta-analyses and meta-analytic structural equation modeling were conducted. RESULTS: Eight psychosocial predictors of physical activity were identified. Self-efficacy (r+ = 0.26) and intentions (r+ = 0.33) were the strongest predictors in bivariate analyses. The structural equation models included attitudes, injunctive norms, self-efficacy, intentions, and physical activity (k = 22, N = 4,385). The model with the best fit, χ2(2) = 0.11, p = .95, root mean square error of approximation = .00, comparative fit index = 1.00, Tucker-Lewis index = 1.00, indicated that all specified paths were significant. Intentions were the strongest predictor of physical activity (ß = 0.27, p < .001), and attitudes and self-efficacy were strong predictors of intentions (both ßs = 0.29, ps < .001). Few significant moderators were observed. CONCLUSION: This review indicates that self-efficacy and intentions are direct predictors of physical activity in cancer survivors. Further, attitudes and norms predict physical activity through intentions. Findings inform intervention development to increase physical activity engagement among cancer survivors.

RESUMEN

BACKGROUND: Genital chlamydia infection in women is often asymptomatic, but may result in adverse outcomes before and during pregnancy. The purpose of this study was to examine the strength of the relationships between chlamydia infection and different reproductive health outcomes and to assess the certainty of the evidence. METHODS: This review was registered and followed the Cochrane guidelines. We searched three databases to quantitatively examine adverse outcomes associated with chlamydia infection. We included pregnancy and fertility-related outcomes. We performed meta-analyses on different study designs for various adverse outcomes using unadjusted and adjusted analyses. RESULTS: We identified 4730 unique citations and included 107 studies reporting 12 pregnancy and fertility-related outcomes. Sixty-eight studies were conducted in high-income countries, 37 studies were conducted in low-income or middle-income countries, and 2 studies were conducted in both high-income and low-income countries. Chlamydia infection was positively associated with almost all of the 12 included pregnancy and fertility-related adverse outcomes in unadjusted analyses, including stillbirth (OR=5.05, 95% CI 2.95 to 8.65 for case-control studies and risk ratio=1.28, 95% CI 1.09 to 1.51 for cohort studies) and spontaneous abortion (OR=1.30, 95% CI 1.14 to 1.49 for case-control studies and risk ratio=1.47, 95% CI 1.16 to 1.85 for cohort studies). However, there were biases in the design and conduct of individual studies, affecting the certainty of the overall body of evidence. The risk of adverse outcomes associated with chlamydia is higher in low-income and middle-income countries compared with high-income countries. CONCLUSION: Chlamydia is associated with an increased risk of several pregnancy and fertility-related adverse outcomes in unadjusted analyses, especially in low-income and middle-income countries. Further research on how to prevent the sequelae of chlamydia in pregnant women is needed. TRIAL REGISTRATION NUMBER: CRD42017056818.

RESUMEN

BACKGROUND: Crowdsourcing is increasingly used to improve community engagement in HIV and sexual health research. In this scoping review, we reviewed studies using crowdsourcing approaches in HIV and sexual health research to identify strengths, opportunities for expansion, and limitations of such approaches. METHODS: We searched CINAHL, Web of Science, Embase, and PubMed. Studies were included if they involved crowdsourcing activities, were in the field of HIV or sexual health, and described the methodology in sufficient detail. We conducted a qualitative synthesis of eligible articles. RESULTS: Our search strategy yielded 431 nonduplicate articles. After screening, 16 articles met the inclusion criteria, including 4 publications that described research from high-income countries, 7 from middle-income countries, 1 from a low-income country, and 4 that had a global focus. There were 4 categories of crowdsourcing: open contests, hackathons, open forums, and incident reporting systems. We identified common phases for data acquisition and dissemination: (1) preparation; (2) problem framing and crowd solicitation; (3) judging submissions; and (4) sharing selected submissions. Strengths of using crowdsourcing approaches include greater innovation due to crowd heterogeneity, encouragement of multisectoral collaboration, empowerment of vulnerable populations, cost-effectiveness, and relevance to local cultures and styles. Weaknesses among some methods include reliance on the internet, temporal transience, and difficulty in sustaining long-term community engagement. CONCLUSIONS: Crowdsourcing may be useful for HIV implementation research. Further research on crowdsourcing related to HIV and sexual health is needed.

RESUMEN

BACKGROUND: Conversational interfaces (CIs) in different modalities have been developed for health purposes, such as health behavioral intervention, patient self-management, and clinical decision support. Despite growing research evidence supporting CIs' potential, CI-related research is still in its infancy. There is a lack of systematic investigation that goes beyond publication review and presents the state of the art from perspectives of funding agencies, academia, and industry by incorporating CI-related public funding and patent activities. OBJECTIVE: This study aimed to use data systematically extracted from multiple sources (ie, grant, publication, and patent databases) to investigate the development, research, and fund application of health-related CIs and associated stakeholders (ie, countries, organizations, and collaborators). METHODS: A multifaceted search query was executed to retrieve records from 9 databases. Bibliometric analysis, social network analysis, and term co-occurrence analysis were conducted on the screened records. RESULTS: This review included 42 funded projects, 428 research publications, and 162 patents. The total dollar amount of grants awarded was US $30,297,932, of which US $13,513,473 was awarded by US funding agencies and US $16,784,459 was funded by the Europe Commission. The top 3 funding agencies in the United States were the National Science Foundation, National Institutes of Health, and Agency for Healthcare Research and Quality. Boston Medical Center was awarded the largest combined grant size (US $2,246,437) for 4 projects. The authors of the publications were from 58 countries and 566 organizations; the top 3 most productive organizations were Northeastern University (United States), Universiti Teknologi MARA (Malaysia), and the French National Center for Scientific Research (CNRS; France). US researchers produced 114 publications. Although 82.0% (464/566) of the organizations engaged in interorganizational collaboration, 2 organizational research-collaboration clusters were observed with Northeastern University and CNRS as the central nodes. About 112 organizations from the United States and China filed 87.7% patents. IBM filed most patents (N=17). Only 5 patents were co-owned by different organizations, and there was no across-country collaboration on patenting activity. The terms patient, child, elderly, and robot were frequently discussed in the 3 record types. The terms related to mental and chronic issues were discussed mainly in grants and publications. The terms regarding multimodal interactions were widely mentioned as users' communication modes with CIs in the identified records. CONCLUSIONS: Our findings provided an overview of the countries, organizations, and topic terms in funded projects, as well as the authorship, collaboration, content, and related information of research publications and patents. There is a lack of broad cross-sector partnerships among grant agencies, academia, and industry, particularly in the United States. Our results suggest a need to improve collaboration among public and private sectors and health care organizations in research and patent activities.

RESUMEN

OBJECTIVES: To evaluate the evidence for a 50,000/µl platelet count threshold for platelet transfusion for invasive dental procedures in thrombocytopenic patients. SUBJECTS AND METHODS: We searched in MEDLINE/PubMed, EMBASE, the Cochrane Library (Wiley) and Scopus from 1960 through April 2018 for studies on patients with quantitative platelet disorders not related to medical co-morbidities or medications and undergoing invasive dental procedures. Two reviewers conducted assessments independently. RESULTS: We found a total of 176 non-duplicate articles, of which 9 cohort studies met our inclusion criteria. The incidence of postoperative bleeding in thrombocytopenic patients was low (4.9%), and we found no difference in bleeding incidence between patients who had platelet transfusion and those who did not. There was no difference in the mean platelet count for patients with and without bleeding. Different modalities are now available to prevent and control bleeding, which may reduce the need for platelet transfusion. CONCLUSIONS: There is no evidence to support the long-standing dogma of a need for a platelet count ≥ 50,000/µl for safe invasive dental procedures. Platelet transfusion effectiveness for haemostasis support could not be determined based on available data. Local measures and antifibrinolytics are the mainstay for the prevention and management of bleeding.

RESUMEN

OBJECTIVE: To evaluate the current evidence regarding the effectiveness of non-opioid interventions for the therapeutic management of pain in head and neck cancer patients with oral mucositis resulting from radiotherapy only or chemoradiotherapy. MATERIALS AND METHODS: A literature search was conducted which included randomised controlled trials that assessed patient-related outcome of pain in patients with oral mucositis associated with radiation therapy only or chemoradiotherapy. Literature searches were conducted in MEDLINE via Pubmed, Embase, Scopus and CINAHL. RESULTS: The electronic searches identified 846 articles. Screening revealed that six articles met all eligibility inclusion criteria. Interventions showing statistically significant benefits to reduce oral mucositis associated pain compared to placebo included doxepin (p < 0.001, 95% CI -6.7 to -2.1), amitriptyline (p = 0.04), diclofenac (p < 0.01) and benzydamine (p = 0.014). CONCLUSIONS: Non-opioid interventions, including topical doxepin, amitriptyline, diclofenac and benzydamine, were found to provide relief of pain due to mucositis, and when effective may allow for reduction in the use of opioids in pain management.

RESUMEN

OBJECTIVE: Evidence suggests peer support (PS) is as an effective strategy for enhancing prevention and control of chronic and infectious diseases, including cancer. This systematic scoping review examines the range and variety of interventions on the use of PS across the cancer care continuum. METHOD: We used a broad definition of PS to capture a wide-range of interventions and characterize the current status of the field. Literature searches were conducted using PubMed, SCOPUS, and CINAHL to identify relevant articles published from January 2011 to June 2016. We screened the title and abstracts of 2087 articles, followed by full-text screening of 420 articles, resulting in a final sample of 242 articles of which the most recent 100 articles were reviewed (published June 2014 to May 2016). RESULTS: A number of the recent intervention studies focused on breast cancer (32%, breast cancer only) or multiple cancer sites (23%). Although the interventions spanned all phases of the cancer care continuum, only 2% targeted end-of-life care. Seventy-six percent focused on clinical outcomes (e.g., screening, treatment adherence) and 72% on reducing health disparities. Interventions were primarily phone-based (44%) or delivered in a clinic setting (44%). Only a few studies (22%) described the impact of providing PS on peer supporters. CONCLUSION: PS appears to be a widely used approach to address needs across the cancer care continuum, with many opportunities to expand its reach.

RESUMEN

OBJECTIVE: Previous work in pediatric oncology has found that clinicians and parents tend to under-report the frequency and severity of treatment-related symptoms compared to child self-report. As such, there is a need to identify high-quality self-report instruments to be used in pediatric oncology research studies. This study's objective was to conduct a systematic literature review of existing English language instruments used to measure self-reported symptoms in children and adolescents undergoing cancer treatment. METHODS: A comprehensive literature search was conducted in MEDLINE/PubMed, EMBASE, CINAHL, and PsycINFO to identify relevant articles published through November 10, 2016. Using pre-specified inclusion/exclusion criteria, six trained reviewers carefully screened abstracts and full-text articles for eligibility. RESULTS: There were 7738 non-duplicate articles identified in the literature search. Forty articles met our eligibility criteria, and within these articles, there were 38 self-report English symptom instruments. Most studies evaluated only cross-sectional psychometric properties, such as reliability or validity. Ten studies assessed an instrument's responsiveness or ability to detect changes in symptoms over time. Eight instruments met our criteria for use in future longitudinal pediatric oncology studies. CONCLUSIONS: This systematic review aids pediatric oncology researchers in identifying and selecting appropriate symptom measures with strong psychometric evidence for their studies. Enhancing the child's voice in pediatric oncology research studies allows us to better understand the impact of cancer and its treatment on the lives of children.

RESUMEN

OBJECTIVE: HIV self-testing (HIVST) is now officially recommended by the WHO, yet much of HIVST evidence to date has focused on quantitative data and hypothetical concerns. Effective scale-up of HIVST in diverse local contexts requires qualitative data from experiences using and organizing HIVST. This qualitative systematic review aims to appraise and synthesize research evidence on experiences using and organizing HIVST. METHODS: We conducted a systematic search of seven primary literature databases, four gray literature sources, and reference lists reporting qualitative evidence on HIVST. Data extraction and thematic analysis were used to synthesize findings. Quality of studies was assessed using the Critical Appraisal Skills Programme tool. Confidence in review findings was evaluated using the Confidence in the Evidence from Reviews of Qualitative Research approach. The review protocol was registered (CRD42015027607). RESULTS: From 1266 potential articles, we included 18. Four studies were conducted in low-income countries, three in middle-income countries, 10 in high-income countries, and one in multiple countries. Generally, HIVST increased capacity to reach priority populations and expanded opportunities for service delivery. Self-testing was preferred to facility-based testing due to increased convenience and confidentiality, especially among stigmatized populations. HIVST decreased test-associated stigma compared with facility-based testing. HIVST generally empowered people because it provided greater control over individual testing needs. At the same time, HIVST rarely allowed husbands to coerce their wives to test. CONCLUSIONS: This review suggests that HIVST should be offered as an additional HIV testing option to expand testing and empower testers. Adapting national policies to incorporate HIVST will be necessary to guide scale-up.

RESUMEN

IMPORTANCE: Major congenital abnormalities, or birth defects, carry significant medical, surgical, cosmetic, or lifestyle consequences. Such abnormalities may be syndromic, involving multiple organ systems, or can be isolated. Overall, 2% to 4% of live births involve congenital abnormalities. Risk factors for birth defects are categorized as modifiable and nonmodifiable. Modifiable risk factors require thorough patient education/counseling. The strongest risk factors, such as age, family history, and a previously affected child, are usually nonmodifiable. OBJECTIVE: This review focuses on risk factors for birth defects including alcohol consumption, illicit drug use, smoking, obesity, pregestational diabetes, maternal phenylketonuria, multiple gestation, advanced maternal age, advanced paternal age, family history/consanguinity, folic acid deficiency, medication exposure, and radiation exposure. EVIDENCE ACQUISITION: Literature review via PubMed. RESULTS: There is a strong link between alcohol use, folic acid deficiency, obesity, uncontrolled maternal diabetes mellitus, uncontrolled maternal phenylketonuria, and monozygotic twins and an increased risk of congenital anomalies. Advanced maternal age confers an increased risk of aneuploidy, as well as nonchromosomal abnormalities. Some medications, including angiotensin converting enzyme inhibitors, retinoic acid, folic acid antagonists, and certain anticonvulsants, are associated with various birth defects. However, there are few proven links between illicit drug use, smoking, advanced paternal age, radiation exposure, and statins with specific birth defects. CONCLUSIONS AND RELEVANCE: Birth defects are associated with multiple modifiable and nonmodifiable risk factors. Obstetrics providers should work with patients to minimize their risk of birth defects if modifiable risk factors are present and to appropriately counsel patients when nonmodifiable risk factors are present.

RESUMEN

Lifestyle interventions targeting gestational weight gain (GWG) report varying degrees of success. To better understand factors influencing efficacy, we reviewed randomized trials specifically among obese and overweight pregnant women. METHODS: We conducted a systematic review and a meta-analysis of 32 studies with a pooled population of 5,869 overweight or obese pregnant women. Random effects models were fit to compute the weighted mean difference (WMD) in GWG between groups across studies. Subgroup analyses were conducted to compare intervention efficacy in overweight vs. obese pregnant women, and interventions delivered by prenatal care providers (PCPs) vs. non-PCPs during pregnancy. Moderator analyses ensured. RESULTS: Nine (28%) of 32 studies reported significant reductions in GWG in response to intervention. Of these, six (66%) of nine were delivered by PCPs. Overall, the WMD in GWG was -1.71 (95% confidence interval [CI]: -2.55, -0.86) kg. However, interventions delivered by PCPs yielded a significantly greater reduction in GWG compared to interventions delivered by non-PCPs (WMD = -3.88 kg; 95% CI: -7.01, -0.75 vs. -0.80 kg; 95% CI: -1.32, -0.28; p for difference = 0.005). CONCLUSION: When PCPs counsel nutrition and physical activity, obese and overweight pregnant women have greater success meeting GWG targets and may be more motivated to modify their behaviour than with other modes of intervention deliveries.

RESUMEN

PURPOSE: Compared with young White women, young Black women are more likely to present with aggressive breast cancer (BC) subtypes that are potentially linked to worse health-related quality of life (HRQOL); however, there is limited consensus regarding HRQOL needs among young Black BC survivors. Employing Ferrell's framework on QOL in BC (i.e., physical, psychological, social, and spiritual well-being), we conducted a systematic review on HRQOL among Black BC survivors aged <50 years and proposed recommendations for advancing HRQOL research and care for this population. METHODS: Literature searches were conducted in MEDLINE/PubMed, EMBASE, CINAHL, and PsycINFO to identify relevant articles published from 1995 to 2015. Abstracts and full-text articles were screened using predetermined inclusion/exclusion criteria and evaluated for quality. RESULTS: A total of 2533 articles were identified, but six met eligibility criteria. Most studies examined multiple HRQOL domains, with the psychological domain most represented. Compared with their older, White, and BC-free counterparts, young Black BC survivors reported greater fear of dying, unmet supportive care needs, financial distress, and lower physical/functional well-being. However, spiritual well-being appeared favorable for young Black survivors. Research gaps include the absence of longitudinal studies and under-representation of studies examining physical, social, and particularly, spiritual HRQOL in young Black BC survivors. CONCLUSIONS: Young Black BC survivors generally experience suboptimal HRQOL after BC diagnosis. As few studies have reported on HRQOL among this group, future research and oncology care should prioritize young Black women in ways that recognize their unique concerns, in order to ensure better HRQOL outcomes both during and after treatment.

RESUMEN

BACKGROUND: Survivorship care plans (SCPs) are written treatment summaries and follow-up care plans that are intended to facilitate communication and coordination of care among survivors, cancer care providers, and primary care providers. A growing number of guidelines for the use of SCPs exist, yet SCP use in the United States remains limited. Limited use of SCPs may be due to poor quality of these guidelines. The purpose of the study was to evaluate the quality of guidelines for SCP use, tools that are intended to promote evidence-based medicine. METHODS: We conducted a comprehensive search of the literature using MEDLINE/PubMed, EMBASE (Excerpta Medica Database), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) published through April 2014, in addition to grey literature sources and bibliographic and expert reviews. Guideline quality was assessed using the AGREE II instrument (Appraisal of Guidelines for Research and Evaluation, 2nd edition), a tool developed by an international group of scientists to advance the quality of clinical practice guidelines. To promote consistency with extant studies using the AGREE II instrument and to clearly and unambiguously identify potentially useful guidelines for SCP use, we also summarized AGREE II scores by strongly recommending, recommending, or not recommending the guidelines that we evaluated. RESULTS: Of 128 documents screened, we included 16 guidelines for evaluation. We did not strongly recommend any of the 16 guidelines that we evaluated; we recommended 5 and we did not recommend 11. Overall, guidelines scored highest on clarity of presentation (i.e., guideline language, structure, and format): Guidelines were generally unambiguous in their recommendations that SCPs should be used. Guidelines scored lowest on applicability (i.e., barriers and facilitators to implementation, implementation strategies, and resource implications of applying the guideline): Few guidelines discussed facilitators and barriers to guideline application; advice and tools for implementing guidelines were vague; and none explicitly discussed resource implications of implementing the guidelines. CONCLUSIONS: Guidelines often advocated survivorship care plan use without justification or suggestions for implementation. Improved guideline quality may promote survivorship care plan use.
