Preference Sensitive Care and Shared Decision-Making in Lumbar Spinal Stenosis: A Scoping Review

STUDY DESIGN

Scoping review.

OBJECTIVE

The objective of this study was to conduct a scoping review exploring the extent to which preference sensitivity has been studied in treatment decisions for lumbar spinal stenosis (LSS), utilizing shared decision-making (SDM) as a proxy.

BACKGROUND

Preference-sensitive care involves situations where multiple treatment options exist with significant tradeoffs in cost, outcome, recovery time, and quality of life. LSS has gained research focus as a preference-sensitive care scenario.

MATERIALS AND METHODS

A scoping review protocol in accordance with "Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews" regulations was registered with the Open Science Framework (ID: 9ewup) and conducted across multiple databases from January 2000 to October 2022. Study selection and characterization were performed by 3 independent reviewers and an unbiased moderator.

RESULTS

The search resulted in the inclusion of 16 studies varying in design and sample size, with most published between 2016 and 2021. The studies examined variables related to SDM, patient preferences, surgeon preferences, and decision aids (DAs). The outcomes assessed included treatment choice, patient satisfaction, and patient understanding. Several studies reported that SDM influenced treatment choice and patient satisfaction, while the impact on patient understanding was less clear. DAs were used in some studies to facilitate SDM.

CONCLUSION

The scoping review identified a gap in comprehensive studies analyzing the preference sensitivity of treatment for LSS and the role of DAs. Further research is needed to better understand the impact of patient preferences on treatment decisions and the effectiveness of DAs in LSS care. This review provides a foundation for future research in preference-sensitive care and SDM in the context of lumbar stenosis treatment.

Cost, Quality, and Utilization After Hospital-Physician and Hospital-Post Acute Care Vertical Integration: A Systematic Review

Vertical integration of health systems-the common ownership of different aspects of the health care system-continues to occur at increasing rates in the United States. This systematic review synthesizes recent evidence examining the association between two types of vertical integration-hospital-physician (n = 43 studies) and hospital-post-acute care (PAC; n = 10 studies)-and cost, quality, and health services utilization. Hospital-physician integration is associated with higher health care costs, but the effect on quality and health services utilization remains unclear. The effect of hospital-PAC integration on these three outcomes is ambiguous, particularly when focusing on hospital-SNF integration. These findings should raise some concern among policymakers about the trajectory of affordable, high-quality health care in the presence of increasing hospital-physician vertical integration but perhaps not hospital-PAC integration.

Disparities Research for Pelvic Floor Disorders: A Systematic Review and Critique of Literature

IMPORTANCE

Understanding the status of pelvic floor disorder (PFD) disparities research will allow the opportunity to advance future pelvic floor equity efforts.

OBJECTIVES

The aims of the study were to (1) characterize the landscape of PFD disparities literature using the 3 phases of disparities research framework, (2) describe the characteristics of PFD disparities studies, and (3) identify critical knowledge gaps.

STUDY DESIGN

We performed a systematic review of peer-reviewed publications addressing disparities in PFDs among U.S. populations from PubMed, Embase, Scopus, or the Cochrane Database indexed between 1997 and 2022. Using the triphasic framework for advancing health disparities research by Kilbourne et al (Am J Public Health. 2006;96(12):2113-21), we categorized the included studies into the detecting phase (identifies and measures disparities in historically marginalized populations), understanding phase (establishes disparity determinants), or reducing phase (conducts interventions to alleviate inequities). All screening, coding, and quality reviews were independently performed by at least 2 authors. We used descriptive analysis and the χ2 test for comparisons.

RESULTS

The initial search identified 10,178 studies, of which 123 were included. Of the included studies, 98 (79.7%), 22 (17.9%), and 3 (2.4%) studies were detecting, understanding, and reducing phase research, respectively. The most common disparity category investigated was race and ethnicity (104 studies), and one third of these studies attributed drivers of racial and ethnic differences to structural influences. Publications of detecting phase studies outpaced the growth of understanding and reducing phase research.

CONCLUSIONS

Most PFD disparities research focused on identifying historically marginalized populations with inadequate progression to understanding and reducing phases. We recommend progressing PFD disparities research beyond the detecting phase to advance health equity in PFD care.

ERS/EBMT clinical practice guidelines on treatment of pulmonary chronic graft-versus-host disease in adults

Chronic graft-versus-host disease (cGvHD) is a common complication after allogeneic haematopoietic stem cell transplantation, characterised by a broad disease spectrum that can affect virtually any organ. Although pulmonary cGvHD is a less common manifestation, it is of great concern due to its severity and poor prognosis. Optimal management of patients with pulmonary cGvHD is complicated and no standardised approach is available. The purpose of this joint European Respiratory Society (ERS) and European Society for Blood and Marrow Transplantation task force was to develop evidence-based recommendations regarding the treatment of pulmonary cGvHD phenotype bronchiolitis obliterans syndrome in adults. A multidisciplinary group representing specialists in haematology, respiratory medicine and methodology, as well as patient advocates, formulated eight PICO (patient, intervention, comparison, outcome) and two narrative questions. Following the ERS standardised methodology, we conducted systematic reviews to address these questions and used the Grading of Recommendations Assessment, Development and Evaluation approach to develop recommendations. The resulting guideline addresses common therapeutic options (inhalation therapy, fluticasone-azithromycin-montelukast, imatinib, ibrutinib, ruxolitinib, belumosudil, extracorporeal photopheresis and lung transplantation), as well as other aspects of general management, such as lung functional and radiological follow-up and pulmonary rehabilitation, for adults with pulmonary cGvHD phenotype bronchiolitis obliterans syndrome. These recommendations include important advancements that could be incorporated in the management of adults with pulmonary cGvHD, primarily aimed at improving and standardising treatment and improving outcomes.

Medical Cannabis and Its Efficacy/Effectiveness for the Treatment of Low-Back Pain: a Systematic Review

PURPOSE OF REVIEW

This systematic review aims to inform the current state of evidence about the efficacy and effectiveness of medical cannabis use for the treatment of LBP, specifically on pain levels and overall opioid use for LBP. Searches were conducted in MEDLINE (PubMed), Embase, and CINAHL. The search was limited to the past 10 years (2011-2021). Study inclusion was determined by the critical appraisal process using the Joanna Briggs Institute framework. Only English language articles were included. Participant demographics included all adult individuals with LBP who were prescribed medical cannabis for LBP and may be concurrently using opioids for their LBP. Study quality and the risk of bias were both evaluated. A narrative synthesis approach was used.

RECENT FINDINGS

A total of twelve studies were included in the synthesis: one randomized controlled trial (RCT), six observational studies (one prospective, four retrospective, and one cross-over), and five case studies. All study results, except for the RCT, indicated a decrease in LBP levels or opioid use over time after medical cannabis use. The RCT reported no statistically significant difference in LBP between cannabis and placebo groups. Low back pain (LBP) affects 568 million people worldwide. In the United States, LBP treatment represents more than half of regular opioid users. With the opioid epidemic, alternative methods, particularly medical cannabis, is now increasingly sought by practicing physicians and patients. Due to its infancy, there is minimal high-quality evidence to support medical cannabis use as a first line treatment for LBP.

Provider prescription of hydroxyurea in youth and adults with sickle cell disease: A review of prescription barriers and facilitators

Sickle cell disease (SCD) is an inherited red blood cell disorder associated with frequent painful events and organ damage. Hydroxyurea (HU) is the recommended evidence-based treatment of SCD. However, among patients eligible for HU, prescription rates are low. Utilizing a scoping review approach, we summarized and synthesized relevant findings regarding provider barriers and facilitators to the prescription of HU in youth and adults with SCD and provided suggestions for future implementation strategies to improve prescription rates. Relevant databases were searched using specified search terms. Articles reporting provider barriers and/or facilitators to prescribing HU were included. A total of 10 studies met the inclusion criteria. Common barriers to the prescription of HU identified by providers included: doubts around patients' adherence to HU and their engaging in required testing, concerns about side effects, lack of knowledge, cost and patient concerns about side effects. Facilitators to the prescription of HU included beliefs in the effectiveness of HU, provider demographics and knowledge. Findings suggest significant provider biases exist, particularly in the form of negative perceptions towards patients' ability to adhere to taking HU and engaging in the required follow-up. Improving provider knowledge and attitudes towards HU and SCD may help improve low prescription rates.

Heart Rate Variability in Psychiatric Disorders: A Systematic Review

Introduction

Heart rate variability (HRV) is a measure of the fluctuation in time interval between consecutive heart beats. Decreased heart rate variability has been shown to have associations with autonomic dysfunction in psychiatric conditions such as depression, substance abuse, anxiety, and schizophrenia, although its use as a prognostic tool remains highly debated. This study aims to review the current literature on heart rate variability as a diagnostic and prognostic tool in psychiatric populations.

Methods

A literature search was conducted using the MEDLINE, EMBASE, Cochrane, and PsycINFO libraries to identify full-text studies involving adult psychiatric populations that reported HRV measurements. From 1647 originally identified, 31 studies were narrowed down through an abstract and full-text screen. Studies were excluded if they enrolled adolescents or children, used animal models, enrolled patients with another primary diagnosis other than psychiatric as outlined by the diagnostic and statistical manual of mental disorders (DSM) V, or if they assessed HRV in the context of treatment rather than diagnosis. Study quality assessment was conducted using a modified Downs and Blacks quality assessment tool for observational rather than interventional studies. Data were reported in four tables: 1) summarizing study characteristics, 2) methods of HRV detection, 3) key findings and statistics, and 4) quality assessment.

Results

There is significant variability between studies in their methodology of recording as well as reporting HRV, which makes it difficult to meaningfully interpret data that is clinically applicable due to the presence of significant bias in existing studies. The presence of an association between HRV and the severity of various psychiatric disorders, however, remains promising.

Conclusion

Future studies should be done to further explore how HRV parameters may be used to enhance the diagnosis and prognosis of several psychiatric disorders.

Implications for implementation and adoption of telehealth in developing countries: a systematic review of China's practices and experiences

The rapid advancement of telehealth technologies has the potential to revolutionize healthcare delivery, especially in developing countries and resource-limited settings. Telehealth played a vital role during the COVID-19 pandemic, supporting numerous healthcare services. We conducted a systematic review to gain insights into the characteristics, barriers, and successful experiences in implementing telehealth during the COVID-19 pandemic in China, a representative of the developing countries. We also provide insights for other developing countries that face similar challenges to developing and using telehealth during or after the pandemic. This systematic review was conducted through searching five prominent databases including PubMed/MEDLINE, Embase, Scopus, Cochrane Library, and Web of Science. We included studies clearly defining any use of telehealth services in all aspects of health care during the COVID-19 pandemic in China. We mapped the barriers, successful experiences, and recommendations based on the Consolidated Framework for Implementation Research (CFIR). A total of 32 studies met the inclusion criteria. Successfully implementing and adopting telehealth in China during the pandemic necessitates strategic planning across aspects at society level (increasing public awareness and devising appropriate insurance policies), organizational level (training health care professionals, improving workflows, and decentralizing tasks), and technological level (strategic technological infrastructure development and designing inclusive telehealth systems). WeChat, a widely used social networking platform, was the most common platform used for telehealth services. China's practices in addressing the barriers may provide implications and evidence for other developing countries or low-and middle- income countries (LMICs) to implement and adopt telehealth systems.

Continuous Subcutaneous Infusion Versus Multiple Daily Injections of Insulin for Pregestational Diabetes in Pregnancy: A Systematic Review and Meta-Analysis

BACKGROUND

The use of continuous subcutaneous insulin infusion (CSII) therapy in pregnancies affected by pregestational diabetes mellitus (DM) has generated mixed outcome data worthy of further investigation. This systematic review and meta-analysis aims to evaluate clinical outcomes associated with CSII versus multiple daily injections (MDIs) in pregnant persons with pregestational DM.

METHODS

A predefined, systematic, librarian-assisted search of MEDLINE (PubMed), Embase, Cochrane Library, Scopus, ClinicalTrials.gov, and World Health Organization International Clinical Trial Registry Platform (published from 2010 to 2022) yielded 3003 studies describing pregnancy outcomes associated with CSII and/or MDI for pregestational DM. The primary exposure was mode of insulin administration, with cesarean delivery and neonatal hypoglycemia as the primary maternal and neonatal outcomes, respectively. Secondary outcomes included hypertensive disorders of pregnancy, first and third-trimester glycemic control, large-for-gestational age (LGA) neonate, preterm birth, neonatal intensive care unit admission, need for respiratory support, hyperbilirubinemia, 5-minute Apgar <7, shoulder dystocia, and perinatal mortality. We calculated pooled odds ratios (OR) with 95% confidence intervals (CI) using random-effects models.

RESULTS

Among 39 eligible studies, 39% of the 5518 pregnancies included were exposed to CSII. Odds of cesarean delivery were higher with CSII (20 studies: 63% vs 56%, odds ratio [OR] 1.3 [95% confidence interval (CI) 1.2-1.5]), but we did not identify a difference in the odds of neonatal hypoglycemia (23 studies: 31% vs 34%, OR 1.1 [95% CI 0.9-1.5]). Among secondary outcomes, only the odds of LGA (20 studies: 47% vs 38%, OR 1.4 [95% CI 1.2-1.6]) were higher in individuals using CSII versus MDI.

CONCLUSIONS

Use of CSII (vs MDI) for pregestational DM in pregnancy is associated with higher odds of cesarean delivery and delivery of an LGA neonate. Further evaluation of how CSII use may influence neonatal size and delivery route is warranted.

Implementation of Home-Based Telerehabilitation of Patients With Stroke in the United States: Protocol for a Realist Review

BACKGROUND

Stroke is a common cause of mortality and morbidity. Insufficient and untimely rehabilitation has been associated with inadequate recovery. Telerehabilitation provides an opportunity for timely and accessible services for individuals with stroke, especially in remote areas. Telerehabilitation is defined as a health care team's use of a communication mode (eg, videoconferencing) to remotely provide rehabilitation services. Telerehabilitation is as effective as facility-based rehabilitation; however, it is infrequently used due to implementation barriers.

OBJECTIVE

The aim of the study is to explore the interaction between the implementation strategies, context, and outcomes of telerehabilitation of patients with stroke.

METHODS

This review will follow four steps: (1) defining the review scope, (2) literature search and quality appraisal, (3) data extraction and evidence synthesis, and (4) narrative development. PubMed via MEDLINE, the PEDro database, and CINAHL will be queried till June 2023 and supplemented with citation tracking and a gray literature search. The relevance and rigor of papers will be appraised using the TAPUPAS (Transparency, Accuracy, Purposivity, Utility, Propriety, Accessibility, and Specificity) and Weight of Evidence frameworks. The reviewers will extract and synthesize data iteratively and develop explanatory links between contexts, mechanisms, and outcomes. The results will be reported according to the Realist Synthesis publication standards set by Wong and colleagues in 2013.

RESULTS

The literature search and screening will be completed in July 2023. Data extraction and analysis will be completed in August 2023, and findings will be synthesized and reported in October 2023.

CONCLUSIONS

This will be the first realist synthesis, uncovering the causal mechanisms to explain how, why, and to what extent implementation strategies impact telerehabilitation adoption and implementation.

Intrauterine Insemination After Human Chorionic Gonadotropin Trigger or Luteinizing Hormone Surge: A Meta-analysis

OBJECTIVE

To assess the odds of pregnancy after intrauterine insemination (IUI) timed by ultrasound monitoring and human chorionic gonadotropin (hCG) administration compared with monitoring luteinizing hormone (LH) levels.

DATA SOURCES

We searched PubMed (MEDLINE), EMBASE (Elsevier), Scopus (Elsevier), Web of Science (Clarivate Analytics), ClinicalTrials.gov (National Institutes of Health), and the Cochrane Library (Wiley) from the inception until October 1, 2022. No language limitations were applied.

METHODS OF STUDY SELECTION

After deduplication, 3,607 unique citations were subjected to blinded independent review by three investigators. Thirteen studies (five retrospective cohort, four cross-sectional, two randomized controlled trials, and two randomized crossover studies) that enrolled women undergoing natural cycle, oral medication (clomid or letrozole), or both for IUI were included in the final random-effects model meta-analysis. Methodologic quality of included studies was assessed with the Downs and Black checklist.

TABULATION, INTEGRATION, AND RESULTS

Data extraction was compiled by two authors, including publication information, hCG and LH monitoring guidelines, and pregnancy outcomes. No significant difference in odds of pregnancy between hCG administration and endogenous LH monitoring was observed (odds ratio [OR] 0.92, 95% CI 0.69-1.22, P=.53). Subgroup analysis of the five studies that included natural cycle IUI outcomes also showed no significant difference in odds of pregnancy between the two methods (OR 0.88, 95% CI 0.46-1.69, P=.61). Finally, a subgroup analysis of 10 studies that included women who underwent ovarian stimulation with oral medications (clomid or letrozole) did not demonstrate a difference in odds of pregnancy between ultrasonography with hCG trigger and LH-timed IUI (OR 0.88, 95% CI 0.66-1.16, P=.32). Statistically significant heterogeneity was noted between studies.

CONCLUSION

This meta-analysis showed no difference between pregnancy outcomes between at-home LH monitoring and timed IUI.

Healthcare-based interventions to address food insecurity during pregnancy: a systematic review

OBJECTIVE

This study was a systematic review aimed to assess published literature regarding healthcare-based interventions addressing food insecurity during pregnancy and their effects on patient-reported, pregnancy, or nutritional outcomes.

DATA SOURCES

A systematic search was performed in February 2022 (subsequently updated in August 2022) using Embase, Medline, Cochrane Library, and Scopus using terms related to food insecurity interventions during pregnancy.

STUDY ELIGIBILITY CRITERIA

Studies examining healthcare-based interventions addressing food insecurity during pregnancy with patient-reported outcomes (eg, program satisfaction), adverse pregnancy outcomes (eg, preterm birth), or nutritional outcomes (eg, dietary intake) were included. Studies using data before 1995, conducted outside the United States, or focused solely on dietary content or the Special Supplemental Nutrition Program for Women, Infants, and Children or Supplemental Nutrition Assistance Program as the intervention of interest were excluded.

METHODS

Of note, 3 authors screened the abstracts and full articles for inclusion. The final cohort included 5 studies. Moreover, 3 authors independently extracted data from each article and assessed the study quality using the Grading of Recommendations, Assessment, Development, and Evaluations and the risk of bias using the National Institutes of Health Study Quality Assessment tools.

RESULTS

Overall, 5 studies describing the interventions addressing food insecurity during pregnancy were included. Study designs included prospective cohort (n=1) and retrospective cohort (n=4) studies. There was heterogeneity in the type of intervention, with 3 using food vouchers, 1 focusing on a group prenatal service with nutrition and food management education, and 1 using a food connection program. Most studies (4 [80%]) shared patient-reported outcomes (eg, food security levels and program utilization rates), with 2 studies examining pregnancy-related outcomes (ie, glucose level, blood pressure, and preterm birth) and 2 studies examining nutritional outcomes. The interventions were associated with improved levels of food insecurity, reduced odds of preterm birth, and improved blood pressure trends; the findings demonstrated a 56% to 81% program utilization rate. All studies exhibited moderate to low study quality, with fair to good internal validity.

CONCLUSION

Although data on healthcare-based interventions targeted at food insecurity during pregnancy are limited, the few studies identified suggest that such interventions may affect pregnancy outcomes. A better understanding of the local scope and context of food insecurity and community-based organizations' efforts not captured by the literature in this area can help inform the development of interventions targeting food access during pregnancy.

Interventions to Reduce Inpatient and Discharge Opioid Prescribing for Postpartum Patients: A Systematic Review

INTRODUCTION

As deaths related to opioids continue to rise, reducing opioid use for postpartum pain management is an important priority. Thus, we conducted a systematic review of postpartum interventions aimed at reducing opioid use following birth.

METHODS

From database inception through September 1, 2021, we conducted a systematic search in Embase, MEDLINE, Cochrane Library, and Scopus including the following Medical Subject Heading (MeSH) terms: postpartum, pain management, opioid prescribing. Studies published in English, restricted to the United States, and evaluating interventions initiated following birth with outcomes including an assessment of change in opioid prescribing or use during the postpartum period (<8 weeks postpartum) were included. Authors independently screened abstracts and full articles for inclusion, extracted data, and assessed study quality using the Grading of Recommendations, Assessment, Development, and Evaluation tool and risk of bias using the Institutes of Health Quality Assessment Tools.

RESULTS

A total of 24 studies met inclusion criteria. Sixteen studies evaluated interventions aimed at reducing postpartum opioid use during the inpatient hospitalization, and 10 studies evaluated interventions aimed at reducing opioid prescribing at postpartum discharge. Inpatient interventions included changes to standard order sets and protocols for the management of pain after cesarean birth. Such interventions resulted in significant decreases in inpatient postpartum opioid use in all but one study. Additional inpatient interventions, including use of lidocaine patches, postoperative abdominal binder, valdecoxib, and acupuncture were not found to be effective in reducing postpartum opioid use during inpatient hospitalization. Interventions targeting the postpartum period included individualized prescribing and state legislative changes limiting the duration of opioid prescribing for acute pain both resulted in decreased opioid prescribing or opioid use.

DISCUSSION

A variety of interventions aimed at reducing opioid use following birth have shown efficacy. Although it is not known if any single intervention is most effective, these data suggest that implementation of any number of interventions may be advantageous in reducing postpartum opioid use.

Patient-Centered Digital Health Records and Their Effects on Health Outcomes: Systematic Review

BACKGROUND

eHealth tools such as patient portals and personal health records, also known as patient-centered digital health records, can engage and empower individuals with chronic health conditions. Patients who are highly engaged in their care have improved disease knowledge, self-management skills, and clinical outcomes.

OBJECTIVE

We aimed to systematically review the effects of patient-centered digital health records on clinical and patient-reported outcomes, health care utilization, and satisfaction among patients with chronic conditions and to assess the feasibility and acceptability of their use.

METHODS

We searched MEDLINE, Cochrane, CINAHL, Embase, and PsycINFO databases between January 2000 and December 2021. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed. Eligible studies were those evaluating digital health records intended for nonhospitalized adult or pediatric patients with a chronic condition. Patients with a high disease burden were a subgroup of interest. Primary outcomes included clinical and patient-reported health outcomes and health care utilization. Secondary outcomes included satisfaction, feasibility, and acceptability. Joanna Briggs Institute critical appraisal tools were used for quality assessment. Two reviewers screened titles, abstracts, and full texts. Associations between health record use and outcomes were categorized as beneficial, neutral or clinically nonrelevant, or undesired.

RESULTS

Of the 7716 unique publications examined, 81 (1%) met the eligibility criteria, with a total of 1,639,556 participants across all studies. The most commonly studied diseases included diabetes mellitus (37/81, 46%), cardiopulmonary conditions (21/81, 26%), and hematology-oncology conditions (14/81, 17%). One-third (24/81, 30%) of the studies were randomized controlled trials. Of the 81 studies that met the eligibility criteria, 16 (20%) were of high methodological quality. Reported outcomes varied across studies. The benefits of patient-centered digital health records were most frequently reported in the category health care utilization on the "use of recommended care services" (10/13, 77%), on the patient-reported outcomes "disease knowledge" (7/10, 70%), "patient engagement" (13/28, 56%), "treatment adherence" (10/18, 56%), and "self-management and self-efficacy" (10/19, 53%), and on the clinical outcome "laboratory parameters," including HbA_1c and low-density lipoprotein (LDL; 16/33, 48%). Beneficial effects on "health-related quality of life" were seen in only 27% (4/15) of studies. Patient satisfaction (28/30, 93%), feasibility (15/19, 97%), and acceptability (23/26, 88%) were positively evaluated. More beneficial effects were reported for digital health records that predominantly focus on active features. Beneficial effects were less frequently observed among patients with a high disease burden and among high-quality studies. No unfavorable effects were observed.

CONCLUSIONS

The use of patient-centered digital health records in nonhospitalized individuals with chronic health conditions is potentially associated with considerable beneficial effects on health care utilization, treatment adherence, and self-management or self-efficacy. However, for firm conclusions, more studies of high methodological quality are required.

Language and Geographic Representation of Neurosurgical Journals: A Meta-Science Study

OBJECTIVE

Medical journals have a role in promoting representation of neurosurgeons who speak primary languages other than English. We sought to characterize the language of publication and geographic origin of neurosurgical journals, delineate associations between impact factor (IF) and language and geographic variables, and describe steps to overcome language barriers to publishing.

METHODS

Web of Science, Scopus, and Ulrich's Serial Analysis system were searched for neurosurgery journals. The journals were screened for relevance. Language of publication, country and World Health Organization region, World Bank income status and gross domestic product, and citation metrics were extracted.

RESULTS

Of 867 journals, 74 neurosurgical journals were included. Common publication languages were English (52, 70.3%), Mandarin (5, 6.8%), and Spanish (4, 5.4%). Countries of publication for the greatest number of journals were the United States (23, 31.1%), United Kingdom (8, 10.8%), and China (6, 8.1%). Most journals originated from the Americas region (29, 39.2%), the European region (28, 37.8%), and from high-income countries (n = 54, 73.0%). Median IF was 1.55 (interquartile range [IQR] 0.89-2.40). Journals written in English (1.77 [IQR 1.00-2.87], P = 0.032) and from high-income countries (1.81 [IQR 1.0-2.70], P = 0.046) had highest median IF. When excluding outliers, there was a small but positive correlation between per capita gross domestic product and IF (β = 0.021, P = 0.03, R² = 0.097).

CONCLUSIONS

Language concordance represents a substantial barrier to research equity in neurosurgery, limiting dissemination of ideas of merit that currently have inadequate outlets for readership. Initiatives aimed at increasing the accessibility of neurosurgical publishing to underrepresented authors are essential.

Recent Advances in Sickle-Cell Disease Therapies: A Review of Voxelotor, Crizanlizumab, and L-glutamine

Sickle-cell disease (SCD) is an inherited hemoglobinopathy, causing lifelong complications such as painful vaso-occlusive episodes, acute chest syndrome, stroke, chronic anemia, and end-organ damage, with negative effects on quality of life and life expectancy. Within the last five years, three new treatments have been approved: L-glutamine in 2017 and crizanlizumab and voxelotor in 2019. We conducted a literature search of these three medications, and of the 31 articles meeting inclusion criteria, 6 studied L-glutamine, 9 crizanlizumab, and 16 voxelotor. Treatment with L-glutamine was associated with decrease in pain crises, hospitalizations, and time to first and second crises, with a decrease in RBC transfusion rate. Barriers to filling and taking L-glutamine included insurance denial, high deductible, and intolerability, especially abdominal pain. Crizanlizumab was associated with a reduction in pain crises and time to first crisis, with reduction in need for opioid use. Adverse effects of crizanlizumab include headache, nausea, insurance difficulty, and infusion reactions. Voxelotor was associated with increased hemoglobin and decreased markers of hemolysis. Barriers for voxelotor use included insurance denial and side effects such as headache, rash, and diarrhea. These three medications represent exciting new therapies and are generally well-tolerated though price and insurance approval remain potential barriers to access. Other studies are ongoing, particularly in the pediatric population, and more real-world studies are needed. The objective of this article is to evaluate post-approval studies of crizanlizumab, voxelotor, and L-glutamine in SCD, with a focus on real-world efficacy, side effects, and prescribing data.

Labour induction for termination of pregnancy with severe fetal anomalies after 24 weeks' gestation: a case series and systematic review of the literature

PURPOSE

Under some circumstances, individuals choose to undergo pregnancy termination for foetal anomalies in the second half of pregnancy. This report provides objective information on the clinical management of such cases and a systematic review of the literature on labour induction outcomes for third-trimester abortion using mifepristone-misoprostol.

MATERIALS AND METHODS

The study is a case series describing outcomes for labour induction abortion for foetal anomalies, at gestational age 24 weeks and beyond. A systematic review was performed, searching PubMed, Embase, and Cochrane databases. Two independent authors reviewed and quality assessed the data from the articles.

RESULTS

During a two-year period, 15 patients met inclusion criteria. Fourteen patients received mifepristone and misoprostol, and one received oxytocin. All delivered vaginally. Thirteen patients delivered within 24 hours of the first misoprostol dose, and half delivered within 12 hours. The average interval from misoprostol initiation to foetal expulsion was 15.5 hours in our series. The systematic review identified nine articles for inclusion, all retrospective studies. Labour induction protocols for mifepristone-misoprostol, reporting of gestational age, and key comparisons varied greatly.

CONCLUSIONS

The case series illustrates successful termination of pregnancy primarily using combined mifepristone-misoprostol. Certainty of current evidence is low, based on the GRADE framework. Future research is necessary on third-trimester outcomes with mifepristone-misoprostol.

The role of blood product removal in intraventricular hemorrhage of prematurity: a meta-analysis of the clinical evidence

INTRODUCTION

Premature neonates have a high risk of intraventricular hemorrhage (IVH) at birth, the blood products of which activate inflammatory cascades that can cause hydrocephalus and long-term neurological morbidities and sequelae. However, there is no consensus for one treatment strategy. While the mainstay of treatment involves CSF diversion to reduce intracranial pressure, a number of interventions focus on blood product removal at various stages including extraventricular drains (EVD), intra-ventricular thrombolytics, drainage-irrigation-fibrinolytic therapy (DRIFT), and neuroendoscopic lavage (NEL).

METHODS

We performed a systematic review and meta-analysis to compare the risks and benefits commonly associated with active blood product removal treatment strategies. We searched MEDLINE, Embase, Scopus, Cochrane Library, and CINAHL databases through Dec 2020 for articles reporting on outcomes of EVDs, thrombolytics, DRIFT, and NEL. Outcomes of interest were rate of conversion to ventriculoperitoneal shunt (VPS), infection, mortality, secondary hemorrhage, and cognitive disability.

RESULTS

Of the 10,398 articles identified in the search, 23 full-text articles representing 22 cohorts and 530 patients were included for meta-analysis. These articles included retrospective, prospective, and randomized controlled studies on the use of EVDs (n = 7), thrombolytics (n = 8), DRIFT therapy (n = 3), and NEL (n = 5). Pooled rates of reported outcomes for EVD, thrombolytics, DRIFT, and NEL for ventriculoperitoneal shunt (VPS) placement were 51.1%, 43.3%, 34.3%, and 54.8%; for infection, 15.4%, 12.5%, 4.7%, and 11.0%; for mortality, 20.0%, 11.6%, 6.0%, and 4.9%; for secondary hemorrhage, 5.8%, 7.8%, 20.0%, and 6.9%; for cognitive impairment, 52.6%, 50.0%, 53.7%, and 50.9%. Meta-regression using type of treatment as a categorical covariate showed no effect of treatment modality on rate of VPS conversion or cognitive disability.

CONCLUSION

There was a significant effect of treatment modality on secondary hemorrhage and mortality; however, mortality was no longer significant after adjusting for year of publication. Re-hemorrhage rate was significantly higher for DRIFT (p < 0.001) but did not differ among the other modalities. NEL also had lower mortality relative to EVD (p < 0.001) and thrombolytics (p = 0.013), which was no longer significant after adjusting for year of publication. Thus, NEL appears to be safer than DRIFT in terms of risk of hemorrhage, and not different than other blood-product removal strategies in terms of mortality. Outcomes-in terms of shunting and cognitive impairment-did not differ. Later year of publication was predictive of lower rates of mortality, but not the other outcome variables. Further prospective and randomized studies will be necessary to directly compare NEL with other temporizing procedures.

Housing instability and adverse perinatal outcomes: a systematic review

OBJECTIVE

Our objective was to conduct a systematic review of the published literature on housing instability during pregnancy and adverse pregnancy outcomes and perinatal healthcare utilization.

DATA SOURCES

We performed a systematic search in November 2020 using Embase, MEDLINE, Cochrane Library, and Scopus using terms related to housing instability during pregnancy, adverse pregnancy outcomes, and perinatal healthcare utilization. The search was limited to the United States.

STUDY ELIGIBILITY CRITERIA

Studies examining housing instability (including homelessness) during pregnancy and adverse pregnancy outcomes (including preterm birth, low birthweight neonates, and maternal morbidity) and perinatal healthcare utilization were included.

METHODS

Two authors screened abstracts and full-length articles for inclusion. The final cohort consisted of 14 studies. Two authors independently extracted data from each article and assessed the study quality using the Grading of Recommendations, Assessment, Development, and Evaluation tool. Risk of bias was assessed using the National Institutes of Health Study Quality Assessment Tools.

RESULTS

All included studies were observational, including retrospective cohort (n=10, 71.4%), cross-sectional observational (n=3, 21.4%), or prospective cohort studies (n=1, 7.1%). There was significant heterogeneity in the definitions of housing instability and homelessness. Most of the studies only examined homelessness (n=9, 64.3%) and not lesser degrees of housing instability. Housing instability and homelessness during pregnancy were significantly associated with preterm birth, low birthweight neonates, neonatal intensive care unit admission, and delivery complications. Among studies examining perinatal healthcare utilization, housing instability was associated with inadequate prenatal care and increased hospital utilization. All studies exhibited moderate, low, or very low study quality and fair or poor internal validity.

CONCLUSION

Although data on housing instability during pregnancy are limited by the lack of a standardized definition, a consistent relationship between housing instability and adverse pregnancy outcomes has been suggested by this systematic review. The evaluation and development of a standardized definition and measurement of housing instability among pregnant individuals is warranted to address future interventions targeted to housing instability during pregnancy.

Mean differences in maternal body mass index and recurrent pregnancy loss: a systematic review and meta-analysis of observational studies

OBJECTIVE

To investigate the association of maternal body mass index (BMI) and recurrent pregnancy loss (RPL).

DESIGN

Systematic review and meta-analysis.

SETTING

Not applicable.

PATIENT(S)

A total of 3,833 women with RPL and 4,083 women as controls.

INTERVENTION(S)

Studies were identified through a search of PubMed, Embase, Scopus, and Cochrane.

MAIN OUTCOME MEASURE(S)

The primary outcome of interest was RPL using the mean differences in maternal BMI as the predictor variable. The results of the meta-analysis were reported as the mean difference with a 95% confidence interval.

RESULT(S)

In total, 892 studies were reviewed. Pooled data from 25 studies suggested that the maternal BMI of women with a history of recurrent pregnancy loss was significantly higher than the BMI of controls, mean difference 0.7 kg/m² [95% confidence interval 0.2-1.3].

CONCLUSION(S)

These findings supported an association between maternal BMI and RPL. Large prospective studies are needed to evaluate the influence of maternal BMI on pregnancy outcomes in women with RPL.

International Urogynecological Consultation: clinical definition of pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

This segment of Chapter 1 of the International Urogynecology Consultation (IUC) on pelvic organ prolapse (POP) reviews the literature on the clinical definition of POP with the intent of creating standard terminology.

METHODS

An international group containing nine urogynecologists and one university-based medical librarian performed a search of the literature using pre-specified search terms in PubMed, Embase, and Scopus. Publications were eliminated if not relevant to the clinical definition of POP, and those articles remaining were evaluated for quality using the Specialist Unit for Review Evidence (SURE). The resulting list of articles was used to inform a comprehensive review and creation of the clinical definition of POP.

RESULTS

The original search yielded 31,931 references, of which 167 were used by the writing group. Ultimately, 78 are referenced in the manuscript.

CONCLUSIONS

The clinical definition of POP for this review of the literature is: "anatomical prolapse with descent of at least one of the vaginal walls to or beyond the vaginal hymen with maximal Valsalva effort WITH the presence either of bothersome characteristic symptoms, most commonly the sensation of vaginal bulge, or of functional or medical compromise due to prolapse without symptom bother."

Vision Outcomes for Pediatric Patients With Optic Pathway Gliomas Associated With Neurofibromatosis Type I: A Systematic Review of the Clinical Evidence

Children with neurofibromatosis type I (NF1) have a higher predisposition for low-grade astrocytomas of the optic pathway, commonly referred to as optic pathway gliomas (OPGs). OPGs can result in visual deterioration. Treatment outcomes in OPG-NF1 management are often reported around tumor stabilization. We sought to compare vision outcomes associated with different OPG treatment strategies to inform about this important functional metric. A meta-analysis exploring the different modalities to treat children with OPG-NF1 was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using multiple databases. Of the 113 articles identified in the search, 23 full text articles, representing 564 patients, were included for review. These articles included retrospective, prospective, and randomized controlled studies on observation (n=9), chemotherapy (n=19), radiation therapy (n=6), and surgery (n=7). Of the patients undergoing observation, 87% (60/69) demonstrated stable acuity. In the chemotherapy studies, 27.3% (72/264) demonstrated improved acuity/visual field and/or visual-evoked potential amplitudes, 39.4% (104/264) stable acuity, and 33.3% (88/264) deterioration. Both the radiation and surgical treatments reported worsening acuity at 90.9% (10/11) and 73.3% (11/15), respectively. Causal associations are not known. Indications for and timing of treatment choice warrant larger scale study to provide further understanding.

Prevalence of pelvic organ prolapse among US racial populations: A systematic review and meta-analysis of population-based screening studies

AIMS

To determine the differences in pooled prevalence rates of symptomatic pelvic organ prolapse (POP) across different US racial/ethnic groups using existing screening-based epidemiologic studies.

METHODS

A systematic search of MEDLINE, EMBASE, Cochrane, and Scopus was conducted to retrieve eligible studies. We included studies that identified POP by either physical exam or questionnaire, conducted in non-gynecologic care-seeking settings, and had a representative sample of US community-dwelling women from more than one racial/ethnic group with prevalence rates reported for each population. Meta-analysis was performed with the pooled estimates calculated, and χ ² tests were performed to examine the associations between race and POP prevalence.

RESULTS

Of the 2604 studies reviewed, 5 were included. One study used physical exam findings while others used questionnaires to identify POP. All but one study demonstrated statistically significant differences in POP prevalence rates based on race/ethnicity. The overall pooled POP prevalence rates were determined for each racial/ethnic group-White women: 10.76% (95% confidence interval [CI], 10.30%-11.22%); Hispanic women: 6.55% (95% CI, 5.83%-7.28%); Black women: 3.80% (95% CI, 3.22%-4.38%); and Asian American women: 3.40% (95% CI, 2.09%-4.71%). There was a significant difference in the pooled prevalence rates among these four racial/ethnic groups (p < 0.01).

CONCLUSIONS

Our study found that White women had the highest pooled POP prevalence rate overall, while Hispanic women had the highest pooled prevalence among minority women. Additionally, American Indians and Pacific Islanders were absent from the current prolapse epidemiologic literature.

Interventions Addressing Social Needs in Perinatal Care: A Systematic Review

Introduction: Health is impacted by a wide range of nonmedical factors, collectively termed the social determinants of health (SDoH). As the mechanisms by which these factors influence wellness and disease continue to be uncovered, health systems are beginning to assess their roles in addressing patient's social needs. This study seeks to identify and analyze clinic-based interventions aimed at addressing patients' social needs in perinatal care, including prenatal, antepartum, and postpartum care.

Methods: We conducted a search of six databases through May 2020 for articles describing screening or intervention activities addressing social needs in at least one SDoH domain as defined by Healthy People 2020. We required that studies include pregnant or postpartum women and be based in a clinical setting.

Results: Thirty-one publications describing 26 unique studies were identified. Most studies were either randomized-controlled trials (n=10) or observational studies (n=7) and study settings were both public and private. The mean age of women ranged from 17.4 to 34.1 years. Most studies addressed intimate partner violence (n=19). The next most common need addressed was social support (n=5), followed by food insecurity (n=3), and housing (n=2). Types of interventions varied from simple screening to ongoing counseling and case management. There was wide heterogeneity in outcomes investigated. Most IPV interventions that included counseling or ongoing support resulted in reduced IPV recurrence and severity. No intervention with only screening showed a reduction in rate of IPV.

Conclusion: This systematic review shines light on several avenues to support pregnant and postpartum women through interventions that embed acknowledgment of social needs and actions addressing these needs into the clinical environment. The results of this review suggest that interventions with counseling or ongoing support may show promise in alleviating social risk factors and improving some clinical outcomes. However, the strength of this evidence is limited by the paucity of studies. More rigorous research is imperative to augment the knowledge of social needs interventions, especially in domains outside of IPV.

Hypocalcemia prevention and management after thyroidectomy in children: A systematic review

INTRODUCTION

Hypocalcemia is the most common complication following thyroidectomy in children. Guidelines to manage post-thyroidectomy hypocalcemia are available for adults, but not children. The objective of this review was to identify practices related to hypocalcemia prevention and management in pediatric patients.

METHODS

We identified studies examining the prevention and management of hypocalcemia in pediatric patients post-thyroidectomy within PubMed, EMBASE, Web of Science and Cochrane databases. Three independent reviewers screened citations and reviewed full-text papers.

RESULTS

A total of 15 studies were included, representing 1552 patients. The overall study quality was weak with lack of randomization and inconsistent outcome reporting. The pooled incidence of hypocalcemia from the 15 studies was 35.5% for transient hypocalcemia and 4.2% for permanent hypocalcemia. All studies discussed post-operative hypocalcemia treatment, with most patients requiring admission for intra-venous calcium therapy. One study described a protocol discharging asymptomatic patients on calcitriol and calcium. Three studies discussed preoperative calcium supplementation in patients at risk of hypocalcemia. No studies examined routine use of calcium and/or vitamin D supplementation to prevent post-operative hypocalcemia.

CONCLUSION

A significant number of children undergoing thyroidectomy develop hypocalcemia. Despite this high incidence, our systematic review demonstrates significant practice variation surrounding post-thyroidectomy hypocalcemia prevention and management in children.

LEVEL OF EVIDENCE

III (systematic review of studies of which some were case-control studies (III) and some were case series (IV)).

Treatment of pediatric cerebral venous sinus thromboses: the role of anticoagulation

BACKGROUND

Cerebral venous sinus thromboses (CVST) occur in children with a variety of etiologies. However, no standard treatment paradigm is established. We sought to identify what treatments have been applied, their outcomes, and the role of anticoagulation in pediatric patients with CVST.

METHODS

A systematic review was conducted exploring all treatments of pediatric CVSTs using PubMed, Embase, Scopus, and Cochrane Library and Cochrane Central Register of Controlled Trials. Studies meeting inclusion criteria were reviewed in full and analyzed for study design, aim, population, interventions, and outcomes.

RESULTS

Of 2946 resultant articles, 51 full-text articles were included. Management of infectious CVST included broad-spectrum antibiotics, surgery, and anticoagulation. Neoplastic and traumatic CVST treatment included anticoagulation. Treatment of CVSTs associated with metabolic abnormalities centered on correction of metabolic derangements, or supplementation where appropriate, and anticoagulation. Autoimmune, congenital, and thrombotic pathway CVSTs were treated with anticoagulation and treatment of the underlying disorder. Unfractionated heparin and low molecular weight heparin were most commonly used and seen to be effective and safe. Uncommonly, endovascular interventions including venous thrombectomy and intravenous injection of thrombolytic therapy were used with varying success.

CONCLUSIONS

While conservative, medical, thombolytic, endovascular, and surgical treatment all have a role in in the treatment of pediatric CVSTs, anticoagulation is commonly applied and found to be safe and effective in pediatrics. Risks and benefits of anticoagulation must be considered on an individual basis as no randomized trials have established a standard of care. Based on our findings, we propose an approach to CVST treatment and look to future study aimed at more clearly delineating treatment dose, duration, and timing of re-evaluation in these patients.

Off-label studies on tofacitinib in dermatology: a review

PURPOSE

Tofacitinib citrate is an oral Janus kinase 1/3 inhibitor approved for rheumatoid arthritis, ulcerative colitis, and active psoriatic arthritis. Tofacitinib is being increasingly used off-label for dermatological conditions, with varying efficacy across recent studies. A review of these studies will be a helpful resource for dermatologists considering the use of tofacitinib for conditions refractory to first-line therapies.

MATERIALS AND METHODS

MEDLINE, Embase, CINAHL Plus, Cochrane Library, Scopus, Web of Science, Clinicaltrials.gov, and the WHO International Clinical Trials Registry Platform were all searched for articles and trials mentioning the term 'tofacitinib', then manually reviewed to identify published data on off-label uses of tofacitinib. The article was structured according to the quality of the evidence available.

RESULTS

Tofacitinib appears to show strong efficacy for numerous dermatologic conditions. Randomized controlled trial data is available for atopic dermatitis, alopecia areata, and plaque psoriasis. Case report and case series data is available for numerous other dermatologic conditions.

CONCLUSION

While tofacitinib has a wide array of immunoregulatory properties, making it a possible candidate for treating many dermatologic conditions refractory to other treatments, further testing is needed to better characterize its efficacy and utility moving forward, as well as its safety and adverse effect profile.
