The impact on quality-of-life following treatment of surgical facial scars with laser-based therapy: a scoping review

Post-surgical scarring impacts quality of life (QOL) and is a significant source of morbidity. Existing treatments targeted at improving the appearance and morbidity of scarring include laser-based therapies. Although lasers are frequently used to improve scar appearance, the effects on QOL are unclear. A scoping review was conducted to assess the impact of laser-based therapy for patients with surgical facial scarring on QOL. Throughout literature review was conducted with the guidance of a medical librarian. Relevant articles underwent two rounds of screening by two, independent reviewers. Data were extracted from each article and later analyzed. Of the four articles analyzed, laser-based therapies were demonstrated as effective in improving QOL for patients with facial scars resultant from surgical intervention. Laser-based therapy should be considered when treating facial scarring resultant from surgical intervention, as it has been shown to improve patient QOL. Standardization of QOL assessment and further studies expanding scar inclusion should be pursued given the paucity of information found through this review.

Prognosis of Acute Low-Tone Hearing Loss Without Vertigo: A Scoping Review

OBJECTIVE

Despite its relatively high prevalence, our understanding of the natural clinical course of acute low-tone hearing loss (ALHL) without vertigo remains incomplete. The purpose of this study is to summarize the findings of studies that evaluated recovery from hearing loss (HL), recurrence and/or fluctuation of HL, and progression to Meniere's Disease (MD) of patients presenting with ALHL without vertigo.

METHODS

A scoping review of the English literature was performed. On May 14, 2020 and July 6, 2022, MEDLINE, Embase, and Scopus were searched to identify articles related to the prognosis of ALHL. To be included, articles had to present outcomes that were clearly distinguishable for patients with ALHL without vertigo. Two reviewers evaluated articles for inclusion and extracted data. Disagreements were adjudicated by a third reviewer.

RESULTS

Forty-one studies were included. There was extensive heterogeneity between studies in regard to defining ALHL, treatment methods, and time of follow-up. Most of the cohorts (39 out of 40) reported partial or complete recovery of hearing in the majority (>50%) of patients, although reports of recurrence were relatively common. Progression to MD was infrequently reported. Shorter time from onset of symptoms to treatment predicted better hearing outcomes in 6 of 8 studies.

CONCLUSION

The literature suggests that although the majority of patients with ALHL experience hearing improvement, recurrence and/or fluctuation are common, and progression to MD occurs in a minority of patients. Additional trials utilizing standardized inclusion and outcome criteria are needed to determine the ideal treatment for ALHL.

Prognostic Tools for Older Women with Breast Cancer: A Systematic Review

Background: Breast cancer is the most common cancer in women, and older patients comprise an increasing proportion of patients with this disease. The older breast cancer population is heterogenous with unique factors affecting clinical decision making. While many models have been developed and tested for breast cancer patients of all ages, tools specifically developed for older patients with breast cancer have not been recently reviewed. We systematically reviewed prognostic models developed and/or validated for older patients with breast cancer. Methods: We conducted a systematic search in 3 electronic databases. We identified original studies that were published prior to 8 November 2022 and presented the development and/or validation of models based mainly on clinico-pathological factors to predict response to treatment, recurrence, and/or mortality in older patients with breast cancer. The PROBAST was used to assess the ROB and applicability of each included tool. Results: We screened titles and abstracts of 7316 records. This generated 126 studies for a full text review. We identified 17 eligible articles, all of which presented tool development. The models were developed between 1996 and 2022, mostly using national registry data. The prognostic models were mainly developed in the United States (n = 7; 41%). For the derivation cohorts, the median sample size was 213 (interquartile range, 81-845). For the 17 included modes, the median number of predictive factors was 7 (4.5-10). Conclusions: There have been several studies focused on developing prognostic tools specifically for older patients with breast cancer, and the predictions made by these tools vary widely to include response to treatment, recurrence, and mortality. While external validation was rare, we found that it was typically concordant with interval validation results. Studies that were not validated or only internally validated still require external validation. However, most of the models presented in this review represent promising tools for clinical application in the care of older patients with breast cancer.

The Association of Race and Ethnicity with Mortality in Pediatric Patients with Congenital Heart Disease: a Systematic Review

CONTEXT

Congenital heart disease (CHD) is a common condition with high morbidity and mortality and is subject to racial and ethnic health disparities.

OBJECTIVE

To conduct a systematic review of the literature to identify differences in mortality in pediatric patients with CHD based on race and ethnicity.

DATA SOURCES

Legacy PubMed (MEDLINE), Embase (Elsevier), and Scopus (Elsevier) STUDY SELECTION: English language articles conducted in the USA focused on mortality based on race and ethnicity in pediatric patients with CHD.

DATA EXTRACTION

Two independent reviewers assessed studies for inclusion and performed data extraction and quality assessment. Data extraction included mortality based on patient race and ethnicity.

RESULTS

There were 5094 articles identified. After de-duplication, 2971 were screened for title and abstract content, and 45 were selected for full-text assessment. Thirty studies were included for data extraction. An additional 8 articles were identified on reference review and included in data extraction for a total of 38 included studies. Eighteen of 26 studies showed increased risk of mortality in non-Hispanic Black patients. Results were heterogenous in Hispanic patients with eleven studies of 24 showing an increased risk of mortality. Results for other races demonstrated mixed outcomes.

LIMITATIONS

Study cohorts and definitions of race and ethnicity were heterogenous, and there was some overlap in national datasets used.

CONCLUSION

Overall, racial and ethnic disparities existed in the mortality of pediatric patients with CHD across a variety of mortality types, CHD lesions, and pediatric age ranges. Children of races and ethnicities other than non-Hispanic White generally had increased risk of mortality, with non-Hispanic Black children most consistently having the highest risk of mortality. Further investigation is needed into the underlying mechanisms of these disparities so interventions to reduce inequities in CHD outcomes can be implemented.

Systematic review and meta-analysis of the effect of adverse childhood experiences (ACEs) on brain-derived neurotrophic factor (BDNF) levels

There is continued interest in identifying dysregulated biomarkers that mediate associations between adverse childhood experiences (ACEs) and negative long-term health outcomes. However, little is known regarding how ACE exposure modulates neural biomarkers to influence poorer health outcomes in ACE-exposed children. To address this, we performed a systematic review and meta-analysis of the impact of ACE exposure on Brain Derived Neurotrophic Factor (BDNF) levels - a neural biomarker involved in childhood and adult neurogenesis and long-term memory formation. Twenty-two studies were selected for inclusion within the systematic review, ten of which were included in meta-analysis. Most included studies retrospectively assessed impacts of childhood maltreatment in clinical populations. Sample size, BDNF protein levels in ACE-exposed and unexposed subjects, and standard deviations were extracted from ten publications to estimate the BDNF ratio of means (ROM) across exposure categories. Overall, no significant difference was found in BDNF protein levels between ACE-exposed and unexposed groups (ROM: 1.08; 95 % CI: 0.93-1.26). Age at sampling, analyte type (e.g., sera, plasma, blood), and categories of ACE exposure contributed to high between-study heterogeneity, some of which was minimized in subset-based analyses. These results support continued investigation into the impact of ACE exposure on neural biomarkers and highlight the potential importance of analyte type and timing of sample collection on study results.

Treatments and outcomes in high-risk gestational trophoblastic neoplasia: A systematic review and meta-analysis

BACKGROUND

High-risk gestational trophoblastic neoplasia (GTN) is rare and treated with diverse approaches. Limited published institutional data has yet to be systematically reviewed.

OBJECTIVES

To compile global high-risk GTN (prognostic score ≥7) cohorts to summarise treatments and outcomes by disease characteristics and primary chemotherapy.

SEARCH STRATEGY

MEDLINE, Embase, Scopus, ClinicalTrials.gov and Cochrane were searched through March 2021.

SELECTION CRITERIA

Full-text manuscripts reporting mortality among ≥10 high-risk GTN patients.

DATA COLLECTION AND ANALYSIS

Binomial proportions were summed, and random-effects meta-analyses performed.

MAIN RESULTS

From 1137 records, we included 35 studies, representing 20 countries. Among 2276 unique high-risk GTN patients, 99.7% received chemotherapy, 35.8% surgery and 4.9% radiation. Mortality was 10.9% (243/2236; meta-analysis: 10%, 95% confidence interval [CI] 7-12%) and likelihood of complete response to primary chemotherapy was 79.7% (1506/1890; meta-analysis: 78%, 95% CI: 74-83%). Across 24 reporting studies, modern preferred chemotherapy (EMA/CO or EMA/EP) was associated with lower mortality (overall: 8.8 versus 9.5%; comparative meta-analysis: 8.1 versus 12.4%, OR 0.42, 95% CI: 0.20-0.90%, 14 studies) and higher likelihood of complete response (overall: 76.6 versus 72.8%; comparative meta-analysis: 75.9 versus 60.7%, OR 2.98, 95% CI: 1.06-8.35%, 14 studies), though studies focused on non-preferred regimens reported comparable outcomes. Mortality was increased for ultra-high-risk disease (30 versus 7.5% high-risk; meta-analysis OR 7.44, 95% CI: 4.29-12.9%) and disease following term delivery (20.8 versus 7.3% following molar pregnancy; meta-analysis OR 2.64, 95% CI: 1.10-6.31%). Relapse rate estimates ranged from 3 to 6%.

CONCLUSIONS

High-risk GTN is responsive to several chemotherapy regimens, with EMA/CO or EMA/EP associated with improved outcomes. Mortality is increased in patients with ultra-high-risk, relapsed and post-term pregnancy disease.

Iranian Public Libraries Can Improve Self-Efficacy in Information Literacy, Especially When School Library Instruction Is Not Preparing Students for Lifelong Learning Readiness

A Review of: Leili, S., Maryam, H., & Mohsen, A. (2020). The effect of information literacy instruction on lifelong learning readiness. IFLA Journal, 46(3), 259-270. https://doi.org/10.1177/0340035220931879 Abstract Objective – To examine the efficacy of information literacy skills instruction on the lifelong learning readiness skills of Iranian public library users. Design – Pre- and post-test experiment. Setting – Two public libraries in Iran. Subjects – Thirty (30) high school students who were active users of two Iranian public libraries. Methods – Thirty (30) participants were randomized into two groups, one of which received information literacy training for seven weeks, while the other group acted as a control. Participants were assessed via three instruments in information literacy and readiness for lifelong learning prior to and at the completion of the training program. The workshops included basic library skills, recognizing needed information skills, information source skills, Internet skills, Internet searching skills, resource instruction, database skills, and general searching skills. Results of pre- and post-test assessments were analyzed with analysis of covariance (ANCOVA). Main Results – The group that received information literacy instruction showed increased readiness for self-directed learning, readiness to overcome deterrents to participation, and improved information literacy. The control group did not show an increase in readiness to respond to triggers for learning or an overall increase in lifelong learning readiness. Conclusion – Information literacy instruction can improve elements of lifelong learning readiness in regular library users. Public libraries in Iran should begin long-term planning to implement this training.

Library Workers Experiencing or Observing Sexual Harassment in University of California Libraries is Commonplace and Commonly Unreported

A Review of: Barr-Walker, J., Hoffner, C., McMunn-Tetangco, E., & Mody, N. (2021). Sexual harassment at University of California Libraries: Understanding the experiences of library staff members. College & Research Libraries, 82(2), 237. https://doi.org/10.5860/crl.82.2.237 Abstract Objective – To identify whether academic library workers at the University of California Libraries (UCL) system experienced or observed sexual harassment and to measure their reporting and disclosure behavior. Design – Anonymous online survey with open and closed-end questions. Setting – All UCL system campuses (Berkeley, Davis, Irvine, Los Angeles, Merced, Riverside, Santa Barbara, Santa Cruz, San Diego, and San Francisco). Subjects – All 1610 non-student employees working in UCL system were invited to participate, 579 (36%) responded. Methods – The authors engaged multiple stakeholder groups to refine and promote this census of UCL non-student workers. The survey was distributed via REDCap and remained open for six weeks of November to December 2018. All questions were optional. Certain demographic information was not collected because respondents might have been identified via deductive disclosure. The first author conducted descriptive statistical analysis and pairs of authors conducted thematic analysis. Main Results – More than half of respondents experienced or observed sexual harassment in the workplace; women were more likely to experience than observe and vice versa for men. Harassment was most likely to be exhibited by a coworker. Less than half of respondents felt that the UCL system administration considered the issue important. Nearly three out of every four respondents who had experienced harassment at work chose not to report or disclose; this did not vary significantly between women and men. Conclusion – Sexual harassment of library workers, often by other library workers, is widespread. Staff training and policies should incorporate the reality of gender harassment and commenting on a person's appearance—the two most common forms of harassment exhibited and observed. 

A Systematic Review of Cognitive Function in Adults with Spina Bifida

Background: Though much research has been done on the cognitive profiles of children, the abilities of patients with SBM as they age into adulthood are not well understood.Objective: Determine if adults with SBM have impairments in overall cognition, attention, executive function, and memory compared to typically developing adults or a standardized population mean.Methods: A medical librarian composed a search of spina bifida, adults, and cognitive function. 549 results were screened using title and abstract. Data were extracted using Covidence review software, including risk of bias assessments. 24 studies were included.Results: Memory impairments, notably working and prospective, have been reported. Results in other domains varied. Average VIQ or PIQ did not imply lack of impairment in other specific domains.Conclusion: Memory impairments should be accounted for and neuropsychological testing should be considered when providing care to adults with SBM. Future longitudinal cognitive aging and interventional studies are needed.

Primary cytoreductive surgery for advanced stage endometrial cancer: a systematic review and meta-analysis

OBJECTIVE

Endometrial cancer uncommonly presents at an advanced stage and little prospective evidence exists to guide the management thereof. We aimed to summarize the evidence about primary cytoreductive surgery in the treatment of advanced stage endometrial cancer.

DATA SOURCES

MEDLINE, Embase, and Scopus databases were searched from inception to September 11, 2020, using search terms representing the themes "endometrial cancer," "advanced stage," and "primary cytoreductive surgery."

STUDY ELIGIBILITY CRITERIA

We included full-text, English reports that included ≥10 patients undergoing primary cytoreductive surgery for advanced stage endometrial cancer and that reported on the outcomes of primary cytoreductive surgery and survival rates based on the residual disease burden.

METHODS

Two reviewers independently screened the studies and with disagreements between the reviewers resolved by a third reviewer. Data were extracted using a standardized form. The percentage of cases reaching maximal (no gross residual disease) and optimal (<1 cm or <2 cm residual disease) cytoreduction were assessed by summing binomials proportions, and the association with survival was assessed using an inverse variance-weighted meta-analysis of logarithmic hazard ratios.

RESULTS

From 1219 unique records identified, 34 studies were selected for inclusion. Studies consisted of single or multi-institutional cohorts of patients collected over a period of 6 to 24 years and included various mixes of histologies (endometrioid, serous, clear cell, and carcinosarcoma) and disease stages (III or IV). In a meta-analysis of the extent of residual disease after primary cytoreductive surgery, we found that 52.1% of cases reached no gross residual disease status (n=18 studies; 1329 patients) and 75% reached <1 cm residual disease status (n=27 studies; 2343 patients). The proportion of cytoreduction for both thresholds was lower for studies of stage IV vs stage III to IV disease (41.4% vs 69.8% for no gross residual disease; 63.2% vs 82.2% for <1 cm residual disease) but did not vary notably by histology. In a meta-analysis of the reported hazard ratios, submaximal (any gross residual disease vs no gross residual disease) and suboptimal (≥1 cm vs <1 cm) cytoreduction thresholds were associated with worse progression-free survival (submaximal hazard ratio, 2.16; 95% confidence interval, 1.45-3.21; I²=68%; suboptimal hazard ratio, 2.55; 95% confidence interval, 1.93-3.37; I²=63%) and overall survival rates (submaximal hazard ratio, 2.57; 95% confidence interval, 2.13-3.10; I²=1%; suboptimal hazard ratio, 2.62; 95% confidence interval, 2.20-3.11; I²=15%). Sensitivity analyses limited to high-quality studies demonstrated consistent results.

CONCLUSION

Among cases of advanced stage endometrial cancer undergoing primary cytoreductive surgery, a significant proportion of patients are left with residual disease, which is associated with worse survival outcomes. Further investigations about the roles of neoadjuvant chemotherapy and primary cytoreductive surgery in prospective trials is warranted in this population.

Healthcare Providers' Vaccine Perceptions, Hesitancy, and Recommendation to Patients: A Systematic Review

Despite vaccines' effectiveness in reducing the rate of preventable diseases, vaccine hesitancy has threatened public health and economies worldwide. Healthcare providers' (HCP) communications and behavior strongly influence patient receptivity and uptake. The goal of this review was to examine HCP vaccine perceptions, knowledge, and reservations and how these attitudes affect their recommendations and vaccination practices. Primary research studies published by 16 September 2020 were searched in PubMed, Web of Science, Embase, CINAHL, and PsycINFO. A 14-item scale was developed for survey study and risk of bias appraisal (SSRBA). In total, 96 papers from 34 countries were included, covering 17 vaccines (HPV and influenza vaccines the most studied). Recommendation was positively associated with provider knowledge and experience, beliefs about disease risk, and perceptions of vaccine safety, necessity, and efficacy. HCP vaccination attitudes and practices varied across specialties, vaccines, and countries; demographic impact was inconclusive. Barriers included anticipation of patient/parental concerns or refusal, lacking clear guidelines, time constraints, and cost. For HPV, vaccines were more often recommended to older, female adolescents and by physicians who discussed sexual health. HCPs are vital advocates for patients and the public, but studies indicated a prevalence of provider hesitancy pertaining to inadequate knowledge, low vaccine confidence, and suboptimal uptake themselves. Improving HCP knowledge and assuring their access to information they deem trustworthy are essential to supporting HCPs' role as "trusted messengers" to promote vaccine acceptance.

Libraries Assist Disaster Survivors with Information Needs and Refuge but Need to Amplify Their Role and What They Offer

A Review of: Braquet, D. M. (2010). Library experiences of Hurricane Katrina and New Orleans flood survivors. LIBRES: Library and Information Science Research Electronic Journal, 20(1), 1. https://www.libres-ejournal.info/528/ Abstract  Objective – Describe the experiences and library usage of patrons displaced by Hurricane Katrina and the New Orleans Flood. Design – A qualitative study with interview components and a questionnaire with open and closed-end questions Setting – New Orleans, Louisiana and surrounding area Subjects – 314 questionnaire respondents and 30 interview (24 face-to-face and 6 phone) participants with 5 individuals completing both Methods – The study consisted of an online questionnaire with open and closed-end questions occurring concurrently with semi-structured interviews conducted over the phone and in person. Individuals were recruited via convenience sample by flyers at public locales in the New Orleans area and electronic mailing lists, forums, blogs, and news sites that catered to the New Orleans community. Main Results – Disaster survivors use libraries for Internet access, information and technology assistance, mental relief, physical refuge, and also view them as symbols of both loss and hope. Library resources (including the physical spaces) allowed survivors to regain a sense of control by helping patrons access local information and experience pre-disaster pastimes, such as leisure reading. Conclusion – The study provides rich description of how libraries can support people displaced by disaster, however just over half of participants did not consider the library a part of their disaster experience. Future research should examine how libraries and library workers can amplify their impact during disasters and disaster recovery, as well as partner with disaster planning and response professionals. 

Assessing the use of low value oncology care following the release of Choosing Wisely guidelines

e18861

Background: Low -value care contributes to the high costs of cancer treatment. Almost a decade has passed since the American Society of Clinical Oncology (ASCO) Choosing Wisely campaign identified costly diagnostic testing, radiographic imaging, and therapies that are routinely utilized in cancer care despite lacking evidence of benefit. We sought to evaluate the impact of ASCO Choosing Wisely guidelines and to identify barriers to and facilitators of guideline adherence. Methods: A systematic review of published literature from 2012-2021 was performed in accordance with PRISMA guidelines on the trend in use of low value oncology care. All ten of ASCO Choosing Wisely Guidelines were selected for inclusion; these included recommendations focused on cancer screening, staging and surveillance imaging, and systemic treatment and support. The following databases were searched for original research based in the United States: PubMed, CINAHL, Embase, Web of Science, Scopus, and ASCO Meeting abstracts. Eligible studies were examined for information on design, population, and study outcomes, which included guideline adherence and facilitators and barriers to implementation. All citations were independently dual-screened in a blinded fashion by authors (AG, MS). Results: 35 independent studies were identified from 3,590 unique citations and included n = 1,130,216 patients. Data sources captured large claims database analyses (13 studies, n = 1,069,289), institutional studies (14 studies, n = 53,358), patient-reported surveys (2 studies, n = 915), and interventional studies (6 studies, n = 6654). Adherence to ASCO Choosing Wisely guidelines ranged from 13% to 100% overall. Use of low value oncology care varied depending on the area of recommendation, such as cancer screening (44% to 77%), staging and surveillance imaging (30% to 100%), and systemic treatment and support (13% to 100%). Adherence was facilitated by: (a) physician awareness of and education around the recommendations; (b) patient engagement; (c) embedded EHR best practice alerts; (d) guideline alignment with insurance payer requirements; and (e) integrated healthcare systems. Barriers to guideline incorporation included perceived patient anxiety and concerns about patient satisfaction; illness-specific practices; and time needed for patient-provider conversations regarding low value care. Conclusions: Adherence to the ASCO Choosing Wisely guidelines is variable across the cancer care continuum. Health system and policy-level interventions are needed to further reduce the overuse of low value care in oncology.

Less radical surgery for early-stage cervical cancer: a systematic review

OBJECTIVE

A systematic review was performed to examine the outcomes of simple hysterectomy for women with low-risk, early-stage cervical cancer.

DATA SOURCES

MEDLINE, Embase, Web of Science, and ClinicalTrials.gov were searched from inception until November 4, 2020.

STUDY ELIGIBILITY CRITERIA

Original research reporting recurrence or survival outcomes among women with early-stage cervical cancer (defined as stage IA2 to IB1 disease) who were treated with simple hysterectomy.

METHODS

Data regarding study characteristics, tumor characteristics, other treatment modalities, adjuvant therapy, recurrence, and survival outcomes were analyzed. Studies that reported both simple hysterectomy and radical hysterectomy outcomes were compared in a subgroup analysis. Summary statistics were reported and eligible studies were further analyzed to determine an estimated hazard ratio comparing simple hysterectomy with radical hysterectomy.

RESULTS

A total of 21 studies were included, of which 3 were randomized control trials, 14 retrospective studies, 2 prospective studies, and 2 population-level data sets. The cohort included 2662 women who underwent simple hysterectomy, of which 36.1% had stage IA2 disease and 61.0% stage IB1 disease. Most cases (96.8%) involved tumors of ≤2 cm in size, and 15.4% of cases were lymphovascular space invasion positive. Approximately 71.8% of women who underwent simple hysterectomy had a lymph node assessment, and 30.7% of women underwent adjuvant chemotherapy or radiation. The most common complications described were lymphedema (24%), lymphocysts (22%), and urinary incontinence (18.5%). The total death rate for studies that reported deaths was 5.5%. By stage, there was a 2.7% mortality rate among IA2 disease and a 7.3% mortality rate among IB1 disease. Of note, 18 studies reported outcomes for both simple and radical hysterectomy, with a 4.5% death rate in the radical hysterectomy group and a 5.8% death rate in the simple hysterectomy group. Estimated and reported hazard ratio demonstrated no significant association for mortality between radical and nonradical surgeries for IA2 disease but potentially increased risk of mortality among IB1 disease. All studies had a moderate to high risk of bias, including the 3 randomized control trials. Level of evidence was limited to III to IV.

CONCLUSION

The use of less radical surgery for women with stage IA2 and small volume IB1 cervical cancers appears favorable. However, there is concern that simple hysterectomy in women with stage IB1 tumors may adversely impact survival. Overall, the quality of studies available is modest, limiting the conclusions that can be drawn from the available literature.

Improvement Science and Implementation Science in Cancer Care: Identifying Areas of Synergy and Opportunities for Further Integration

Efforts to improve cancer care primarily come from two fields: improvement science and implementation science. The two fields have developed independently, yet they have potential for synergy. Leveraging that synergy to enhance alignment could both reduce duplication and, more importantly, enhance the potential of both fields to improve care. To better understand potential for alignment, we examined 20 highly cited cancer-related improvement science and implementation science studies published in the past 5 years, characterizing and comparing their objectives, methods, and approaches to practice change. We categorized studies as improvement science or implementation science based on authors' descriptions when possible; otherwise, we categorized studies as improvement science if they evaluated efforts to improve the quality, value, or safety of care, or implementation science if they evaluated efforts to promote the implementation of evidence-based interventions into practice. All implementation studies (10/10) and most improvement science studies (6/10) sought to improve uptake of evidence-based interventions. Improvement science and implementation science studies employed similar approaches to change practice. For example, training was employed in 8/10 implementation science studies and 4/10 improvement science studies. However, improvement science and implementation science studies used different terminology to describe similar concepts and emphasized different methodological aspects in reporting. Only 4/20 studies (2 from each category) described using a formal theory or conceptual framework to guide program development. Most studies were multi-site (10/10 implementation science and 6/10 improvement science) and a minority (2 from each category) used a randomized design. Based on our review, cancer-related improvement science and implementation science studies use different terminology and emphasize different methodological aspects in reporting but share similarities in purpose, scope, and methods, and are at similar levels of scientific development. The fields are well-positioned for alignment. We propose that next steps include harmonizing language and cross-fertilizing methods of program development and evaluation.

Homeless Patrons Utilize the Library for More than Shelter but Public Library Services Are Not Designed with Them in Mind

A Review of: Dowdell, L., & Liew, C. L. (2019). More than a shelter: Public libraries and the information needs of people experiencing homelessness. Library & Information Science Research, 41(4), 100984. https://doi.org/10.1016/j.lisr.2019.100984 Abstract Objective – The study sought to examine the information seeking behavior of homeless patrons and how public libraries meet the needs of homeless patrons. Design – Qualitative phenomenological study. Setting – Public libraries in New Zealand. Subjects – Four homeless patrons who were current library patrons and seven public library workers (senior managers and two front line workers). Methods – Purposive convenience sample of homeless patrons and library workers to participate in face-to-face, semi-structured interviews. The study utilized Creswell's four-step data analysis spiral to produce a synthesis. Main Results – Homeless patrons utilize public libraries for far more than daytime shelter, patronizing the collections, and accessing services. The participating libraries did not have existing policies, practices, services, or staff designed for the needs and wants of homeless people, however, current offerings largely met the needs of homeless patrons. Conclusion – Homeless people use public libraries much like non-homeless patrons and public libraries could develop specialized offerings for them, though they must take care to do so in a way that does not further marginalize this group. Additional research is needed to understand why some homeless people do not utilize the libraries. 

Coronavirus Spectrum Infections (COVID-19, MERS, SARS) in Cancer Patients: A Systematic Review of the Literature

BACKGROUND

Coronavirus 2019 (COVID-19) has spread rapidly around the world to become a global pandemic. There is limited data on the impact of COVID-19 among patients with cancer.

METHODS

A systematic review was performed to determine outcomes of adult patients with cancer affected by coronavirus infections, specifically SARS, MERS, and COVID-19. Studies were independently screened by two reviewers and assessed for quality and bias. Outcomes measured included study characteristics, cancer type, phase of care at the time of diagnosis, and clinical presentation. Morbidity and mortality outcomes were analyzed to assess the severity of infection as compared to the general population.

RESULTS

A total of 19 studies with 110 patients were included. Of these, 66.4% had COVID-19 infections, 32.7% MERS and only one patient with SARS. The majority of COVID-19 studies were based on studies in China. There was a 56.6% rate of a severe event, including ICU admission or requiring mechanical ventilation, with an overall 44.5% fatality rate.

CONCLUSIONS

Patients with cancer with coronavirus infections may be more susceptible to higher morbidity and mortality.

The Affordable Care Act's Medicaid Expansion and Impact Along the Cancer-Care Continuum: A Systematic Review

BACKGROUND

Health reform and the merits of Medicaid expansion remain at the top of the legislative agenda, with growing evidence suggesting an impact on cancer care and outcomes. A systematic review was undertaken to assess the association between Medicaid expansion and the goals of the Patient Protection and Affordable Care Act in the context of cancer care. The purpose of this article is to summarize the currently published literature and to determine the effects of Medicaid expansion on outcomes during points along the cancer care continuum.

METHODS

A systematic search for relevant studies was performed in the PubMed/MEDLINE, EMBASE, Scopus, and Cochrane databases. Three independent observers used an abstraction form to code outcomes and perform a quality and risk of bias assessment using predefined criteria.

RESULTS

A total of 48 studies were identified. The most common outcomes assessed were the impact of Medicaid expansion on insurance coverage (23.4% of studies), followed by evaluation of racial and/or socioeconomic disparities (17.4%) and access to screening (14.5%). Medicaid expansion was associated with increases in coverage for cancer patients and survivors as well as reduced racial- and income-related disparities.

CONCLUSIONS

Medicaid expansion has led to improved access to insurance coverage among cancer patients and survivors, particularly among low-income and minority populations. This review highlights important gaps in the existing oncology literature, including a lack of studies evaluating changes in treatment and access to end-of-life care following implementation of expansion.

Patients' Health Information Practices and Perceptions of Provider Knowledge in the Case of the Newly Discovered Alpha-gal Food Allergy

BACKGROUND

Alpha-gal food allergy is a life-threatening, newly discovered condition with limited presence in authoritative information sources. Sufferers seeking diagnosis are likely to encounter clinicians unfamiliar with the condition.

OBJECTIVE

To understand information practices of individuals diagnosed with alpha-gal allergy, how they obtained diagnosis, and their perceptions of health-care providers' awareness of the condition.

METHODS

Semistructured interviews with open- and closed-ended questions were completed with a chronological systematic sample of 28 adults (11% of alpha-gal clinic patients at the time) diagnosed with alpha-gal allergy and treated at University of North Carolina Allergy and Immunology Clinic.

RESULTS

The majority of patients determined they had alpha-gal allergy through nontraditional health information channels. Three-quarters of patients rated their primary care provider as having little to no knowledge. In 25 specialists' encounters, 23 were rated as having little to no knowledge.

CONCLUSION

With new conditions, information is often available through informal networks before appearing in the vetted medical literature. In this study, social connections were the primary pathway to successful diagnosis. Health practitioners need to develop mechanisms to understand that process.

A constant conversation: tuning into and harmonizing the needs and priorities of the body and mind

Purpose: Individuals rely upon many types of information to manage an illness, including information provided by their own bodies. This study investigated how people tune into and manage the flow of information from their bodies to manage their health. Method: We developed a platform for participants to share and collaboratively reflect on how they engaged in this dialogic process, in which participants contributed to a discussion on topics relating to body listening and body awareness. Though the study was open to anyone interested in or wanting to contribute to knowledge on “body listening,” the social media recruitment focused on chronic conditions requiring self-care and having overlapping symptomatology, with chronic pain as the primary characteristic. A qualitative analysis method based on grounded theory was used to analyse the data. Results: Six main themes emerged: learning the language, recognizing and heeding limits, experiencing emotional fatigue and despair, regulating the channel, moving from conflict to communication, and settling into an uneasy acceptance. Conclusion: The monitoring and filtering of information from one’s body, and the appeasement of conflicting demands and voices, is difficult work. Knowledge of this process can be used in patient education and in the development of tools to support body listening.

Audit responses: responses maintained by access to existing self or coactor scores during non-social, parallel work, and cooperation procedures

Human subjects, mostly between 11 and 16 yr old, matched to sample for points that were exchangeable for money. An audit response was defined as a response maintained by allowing a subject access to an existing score on his own (self audit) or a coactor's (coactor audit) performance. In Experiment I, changes from non-social procedures (no coactor) to social procedures (coactor present) increased self and coactor audits. Since both types of audits occurred at about the same rates during cooperation and parallel work procedures, the increases did not depend on the subjects' response interactions. Although Experiment I did not demonstrate that subjects were comparing scores, the frequent occurrence of each kind of audit within a brief time period (interpersonal audit) did indicate that it was reinforcing to have both scores at the same time. These interpersonal audits suggested that the coactor's score increased self audits during social procedures. Experiment II supported this notion: relative to a non-social procedure, self audits increased more during a parallel work procedure when the coactor's score was accessible than when it was not accessible. Thus, increases in other behaviors that occur in the presence of a coactor, i.e., social facilitation, may also result from or be increased by providing a coactor's score.

Family violence

Domestic and intimate partner abuse, child and adolescent physical and sexual abuse, and elder abuse constitute family violence. Such violence is responsible for a significant proportion of intentional injury and, accordingly, is a major public health problem. This chapter provides information on aspects of each type of family violence.

Psychiatric disorders in adolescents exposed to domestic violence and physical abuse

The relationship between abuse and psychiatric diagnoses was investigated in two groups of physically abused adolescents, 57 living in homes with interparental violence and 32 in homes without such violence, and in 96 nonabused adolescents living in nonviolent homes. Adolescents in the first group were found to be at greater risk for depression, separation anxiety disorder, post-traumatic stress disorder, and oppositional defiant disorder than were those in the second group. Adolescents in the first group also appeared more vulnerable to anxiety and depression.

Child and adolescent abuse and neglect research: a review of the past 10 years. Part I: Physical and emotional abuse and neglect

OBJECTIVE

To review the clinically relevant literature on the physical and emotional abuse and neglect of children and adolescents published during the past 10 years.

METHOD

Literature published between 1988 and 1998 was reviewed following a systematic search of Medline, Psychinfo, and the National Clearinghouse on Child Abuse and Neglect.

RESULTS

During the last decade there has been substantial progress in understanding the symptomatology associated with maltreatment. However, prevention and intervention research studies are relatively rare and frequently have important methodological limitations.

CONCLUSIONS

Child maltreatment research in the next decade needs to focus on understanding factors leading to resilient outcomes and on assessing the effectiveness of psychotherapeutic and psychopharmacological treatment strategies. Increased resources are needed to support child maltreatment research studies and investigators.

Physically abused adolescents: behavior problems, functional impairment, and comparison of informants' reports

OBJECTIVE

This study, like earlier studies that focused on younger abused children, ascertained whether physically abused adolescents exhibited increased internalizing and externalizing behaviors. Relevance to pediatric practice is discussed.

DESIGN

A cross-sectional design was used to compare the behavior of physically abused adolescents and comparison adolescents using self-reports, parent reports, and teacher reports. The level of agreement among raters was also examined.

PARTICIPANTS

The subjects were 99 physically abused adolescents between the ages of 12 and 18 years, who were recruited from Child Protective Services. Comparison subjects were 99 community-recruited nonabused adolescents who were matched for age, gender, and income with the abused adolescents.

MEASURES

The behavior of the adolescents was assessed using the Child Behavior Checklist, and the comparable Youth Self-Report and Teacher Report Form, which are widely used measures of behavioral and emotional problems. The Child Global Assessment Scale was also used as a measure of functional impairment and of the need for mental health services.

RESULTS

Parents and teachers rated the problems of abused adolescents as significantly greater than the problems of nonabused adolescents on all checklist subscales. Abused adolescents reported significantly greater problems only on externalizing behavior subscales. In addition, based on interviewer ratings, physically abused adolescents exhibited significantly greater functional impairment.

CONCLUSIONS

Similar to previous research on abused children, physically abused adolescents exhibit externalizing and internalizing behavior problems and experience greater functional impairment. Parent, teacher, and adolescent reports of externalizing behaviors were similar, but physically abused adolescents reported fewer internalizing behaviors than did the other informants.

Palmar fracture dislocation of the proximal interphalangeal joint

Palmar fracture dislocation of the proximal interphalangeal joint is uncommon. Thirteen patients treated for this injury were retrospectively reviewed. There were 9 acute injuries. Seven were treated by closed reduction and percutaneous pin fixation and 2 were treated by open reduction and internal fixation. The 4 chronic injuries (more than 1 month after injury) were treated with open reduction and soft tissue reconstruction. The length of follow-up averaged 55 months. Eight patients were free from pain. Postoperative proximal interphalangeal motion averaged 91 for the acute injuries and 70 degrees for the chronic injuries. Follow-up radiographic findings were notable for an increased height of the middle phalangeal base in 6 patients, articular irregularity in 4, and residual subluxation in 2; however, these changes did not correlate with the clinical results. Complications included loss of reduction in 1 patient, progressive swan neck deformity in 1, and development of an average 25 degrees extension lag of the distal interphalangeal joint in 5.

The Stener lesion revisited: a case report

Proximal displacement of a ruptured ulnar collateral ligament of the metacarpophalangeal joint of a thumb (Stener lesion) can result in chronic instability if left untreated. Rupture without displacement generally leads to complete recovery. An associated fracture can give information about the position of the ruptured ligament. However, 2 cases are presented demonstrating that displacement of the ligament can occur in the absence of displacement of the bony fragment. This suggests that physical examination is required to determine stability with injuries to the ulnar structures of the thumb metacarpophalangeal joint.

Adolescent physical abuse: risk for adolescent psychiatric disorders

OBJECTIVE

The present study examined whether physical abuse functions as an additional risk factor for adolescent psychopathology after other important known risk factors are controlled for.

METHOD

The authors recruited 99 adolescents aged 12 to 18 years directly from the New York State Department of Social Services after official documentation of physical abuse. The abused adolescents were compared to 99 nonabused adolescents matched for age, gender, race, and community income. Diagnostic interviews and measures of selected risk factors for psychopathology were administered to the adolescents and their parents and then entered into a multiple logistic regression model testing the added risk contributed by physical abuse to adolescent psychopathology.

RESULTS

Physical abuse added significantly to other risk factors in accounting for lifetime diagnoses of major depression, dysthymia, conduct disorder, drug abuse, and cigarette smoking. Physical abuse also contributed significantly to prediction of current adolescent unipolar depressive disorders, disruptive disorders, and cigarette smoking.

CONCLUSIONS

Since physically abused adolescents are at greater risk for the development of psychiatric disorders, recognition of adolescent abuse and the provision of psychiatric and substance abuse services may reduce morbidity.

Adolescent physical abuse and suicide attempts

OBJECTIVE

The rate of suicide attempts and the exposure to risk factors for suicide in an unselected sample of confirmed cases of physically abused adolescents recruited directly from the New York State Central Register for Nassau and Suffolk Counties was compared with those of a community sample of nonabused adolescents.

METHOD

Semistructured and structured diagnostic interviews were used in the assessment of psychopathology of adolescents and their parents

RESULTS

The proportion of adolescents attempting suicide did not differ for the two groups. However, the abused adolescents showed significantly greater exposure to risk factors for adolescent suicide, including family disintegration, and diagnoses of depression, disruptive behavior disorders, and substance abuse and dependence. Comparisons of the 8 physically abused adolescents who attempted suicide with the 91 who did not attempt suicide showed that the following factors were associated with significantly greater risk for suicide attempts: adolescents' perceptions of their families as lacking cohesiveness and maternal support, higher adolescent "hostility" ideation scores, adolescent diagnoses of disruptive disorders and conduct disorders, adolescent substance abuse/dependence, and exposure to a suicide attempt by a family member or a friend.

CONCLUSION

A transactional model of abuse, family and personal stressors, and the development of adolescent vulnerability leading to psychopathology is offered to explain the results.

Implementation of discharge plans for chronically ill elders discharged home

Although discharge plans are viewed as the primary means to ensure that patients' needs will be met in the posthospital environment, little is known about the implementation of arranged care. This study addressed the extent to which discharge plans for elderly patients with congestive heart failure were implemented as planned, tested the consequences of implementation problems, and identified factors associated with implementation problems. For 40 percent of patients, one or more components of the discharge plan were not implemented as planned, with discrepancies more likely among low-income patients. Implementation discrepancies had negative consequences in terms of unmet needs, deficient quantity of help, and less than adequate care. Implications for hospital discharge planners and home health care are discussed.

Predictive Factors in the Non-Surgical Treatment of Carpal Tunnel Syndrome

To identify which patients are likely to respond the medical management of carpal tunnel syndrome, 331 hands in 229 patients were evaluated. They were then treated with a wrist splint and anti-inflammatory medication. Follow-up averaged 15.4 months (minimum six months). Treatment was successful in 18.4%. Statistical evaluation identified five factors which were important in predicting response to treatment: age over 50 years, duration over ten months, constant paraesthesiae, stenosing flexor tenosynovitis, and a Phalen’s test positive in less than 30 seconds. When none of these factors was present, two-thirds of patients were cured by medical therapy. 59.6% of patients with one factor, 83.3% with two factors, and 93.2% with three factors failed. No patient with four or five factors present was cured by medical management.

Defining suicide: Importance and implications for Judaism

One of the more problematic situations in the Jewish tradition is seeing to the psychological needs of the family of a suicide. This is due to the legal statements found within the tradition, placing some restrictions on the funeral rite. As a result of this, the criteria for the suicide are to be well examined and understood to ensure proper pastoral care.

Trochanteric advancement for recurrent dislocation after total hip arthroplasty

Twenty-one patients had trochanteric advancement after experiencing an average of 3.9 dislocations in a mean period of 46 weeks following total hip arthroplasty. Before trochanteric advancement was performed, component malposition and mechanical impingement were excluded as causes of dislocation. Radiographic measurements revealed that the trochanter was advanced an average of 16 +/- 7.7 mm (1 SD). Four patients, all with rheumatoid arthritis, had trochanteric migration greater than 1 cm. Seventeen of the 21 hips had no further dislocations following trochanteric advancement, with mean follow-up period of 2.7 years. Two patients dislocated because of extremes in hip position and had no further dislocations. Two patients dislocated who had trochanteric migration greater than 1 cm. Only one patients with a technically satisfactory trochanteric advancement continued to dislocate repeatedly. In patients without component malposition or obvious sources of impingement, trochanteric advancement is an effective and safe procedure for prevention of recurrent dislocations after total hip arthroplasty.

Monitoring the healing of a tibial osteotomy in the rabbit treated with external fixation

Fracture site axial rigidity was monitored non-destructively at weekly intervals during healing of tibial osteotomies in adult rabbits. Two groups of 20 rabbits each were treated with external fixators of two different rigidities. Four animals from each group were killed at 3, 5, 6, 7, and 8 weeks to determine the bending moments at failure of the healing fractures. Normal fracture healing was accompanied by characteristic phases in the development of fracture site axial rigidity. From 0 to 3 weeks there was a period of low and approximately constant rigidity, followed by a linear increase during 3 to 5 weeks to an approximately three to four times greater rigidity. The maximum average normalized axial rigidities were reached at 6 weeks and were 57% (high rigidity group) and 77% (low rigidity group) of the untreated contralateral controls. The maximum average normalized failure moments occurred at 8 weeks and were 48% (high rigidity) and 44% (low rigidity) of controls. The differences due to fixator rigidity were not statistically significant except for a large increase in failure moments at 3 weeks for the low rigidity group. Axial rigidities were correlated (r2 = 0.74 and 0.53, respectively) with failure moments, but only during the first 6 weeks. The monitoring technique provides a nondestructive means for following the biomechanical progress of fracture healing in an animal model. The occurrence of the characteristic increase in fracture site axial rigidity at 3 to 5 weeks can also be used to distinguish between normal and abnormal healing.

Tensile strength of bovine trabecular bone

Data on the tensile and compressive properties of trabecular bone are needed to define input parameters and failure criteria for modeling total joint replacements. To help resolve differences in reports comparing tensile and compressive properties of trabecular bone, we have developed new methods, based on porous foam technology, for tensile testing of fresh/frozen trabecular bone specimens. Using bovine trabecular bone from an isotropic region from the proximal humerus as a model material, we measured ultimate strengths in tension and compression for two groups of 24 specimens each. The average ultimate strength in tension was 7.6 +/- 2.2 (95% C.I.) MPa and in compression was 12.4 +/- 3.2 MPa. This difference was statistically significant (p = 0.013) and was not related to density differences between the test groups (p = 0.28). Strength was related by a power-law function of the local apparent density, but, even accounting for density influences, isotropic bovine trabecular bone exhibits significantly lower strengths in tension than in compression.

Implications of the personality assessment system for marital counseling: a pilot study

In a pilot study utilizing the Personality Assessment System, WAIS data for 76 couples seen in marriage counseling are analyzed. Husband's scores, wife's scores, and therapeutic outcome are used to classify the couples into contingency tables, which are then treated using remarkability statistics. The hypothesis that the results will be interesting is supported, and a few individually remarkable effects are isolated, including effects describable as “assortative mating” as well as sex differences and certain within-couple configural effects. In view of the large number of marginal findings, the most important implication is that a larger-scale study will be even more interesting.

Vasoactive intestinal peptide secreting tumors of childhood

A 2-year-old boy with failure to thrive, watery diarrhea, abdominal distention, hypokalemia, metabolic acidosis, and episodes of hypertension and sweating was found to have a calcified right lower quadrant mass. Blood levels of vasoactive intestinal peptide (VIP) and norepinephrine (NE) were elevated. Presurgical management with phenoxybenzamine hydrochloride and metyrosine was associated with an absence of expected postoperative hypotension, and resection of a benign ganglioneuroma resulted in prompt relief of all symptoms and return to normal of VIP and NE levels. Evidence supports the theory that VIP is the substance responsible for the diarrhea that accompanies some neural crest tumors.

Pemphigus vegetans: its relationship to eosinophilic spongiosis and favorable response to dapsone

Two cases of pemphigus vegetans are presented. One, an example of the Hallopeau type of the disease, was found to have early lesions that simulated eosinophilic spongiosis clinically and histologically. The other had lesions that were largely confined to the oral mucosa and was also considered to be the Hallopeau type of the disease in a limited form. The cases of these two patients were compared with a typical case of eosinophilic spongiosis. All were controlled with dapsone therapy.

[Chagas-Mazza disease. Preliminary basic social study]

Chagas-Mazza disease is an endemic infection of chronic evolution and is essentially American. Its transmission by vinchuca in Argentine has created a medical, psychological and social problem of great and important significance. The basic, preliminary and social study carried out in a hospital unit, showed in the population attended, precarious socioenvironmental conditions during childhood and adolescence and the almost total lack of basic information on the disease. Interviews, inquests, questionnaires, group actions, team work, direct dialogues, counselling and guidance groups and the guiding to specialized institutions, constitute a synthesis of the task developed which, in its preliminary stage, showed sufficient reasons to continue the control of health during pregnancy, childbirth, puerperium and lactation.
