RESUMO
BACKGROUND: There is a growing interest in employing community wellness worker models in Indigenous populations to address inequities in healthcare access and outcomes, concerns about shortage in health and mental health human resources, and escalating burden of chronic and complex diseases driving significant increase in health services demand and costs. A thorough review of Indigenous community wellness worker models has yet to be conducted. This rapid review sought to outline the characteristics of a community wellness worker model in Indigenous contexts across the globe, detailing factors shaping implementation challenges and success. METHODS: A rapid review of the international peer-reviewed and grey literature of OVID Medline, Global Index Medicus, Google, and Google Scholar was conducted from January to June 2022 for Indigenous community wellness/mental health worker models and comparative models. Articles were screened and assessed for eligibility. From eligible articles, data pertaining to study design and sample; description of the program, service, or intervention; model development and implementation; terminology used to describe workers; training features; job roles; funding considerations; facilitators and barriers to success; key findings; outcomes measured; and models or frameworks utilized were extracted. Data were synthesized by descriptive and pattern coding. RESULTS: Twenty academic and eight grey literature articles were examined. Our findings resulted in four overarching and interconnected themes: (1) worker roles and responsibilities; (2) worker training, education, and experience; (3) decolonized approaches; and (4) structural supports. CONCLUSION: Community wellness worker models present a promising means to begin to address the disproportionately elevated demand for mental wellness support in Indigenous communities worldwide. This model of care acts as a critical link between Indigenous communities and mainstream health and social service providers and workers fulfill distinctive roles in delivering heightened mental wellness supports to community members by leveraging strong ties to community and knowledge of Indigenous culture. They employ innovative structural solutions to bolster their efficacy and cultivate positive outcomes for service delivery and mental wellness. Barriers to the success of community wellness worker models endure, including power imbalances, lack of role clarity, lack of recognition, mental wellness needs of workers and Indigenous communities, and more.

PURPOSE: In many countries, there are calls to address health inequalities experienced by Indigenous people. Preference-based measures (PBMs) provide a measurement of health-related quality of life and can support resource allocation decisions. This review aimed to identify, summarize, and appraise the literature reporting the use and performance of PBMs with Indigenous people. METHODS: Eleven major databases were searched from inception to August 31, 2022. Records in English that (1) assessed any measurement property of PBMs, (2) directly elicited health preferences, (3) reported the development or translation of PBMs for Indigenous people, or (4) measured health-related quality of life (HRQL) using PBMs were included. Ethically engaged research with Indigenous people was considered as an element of methodological quality. Data was synthesized descriptively (PROSPERO ID: CRD42020205239). RESULTS: Of 3139 records identified, 81 were eligible, describing psychometric evaluation (n = 4), preference elicitation (n = 4), development (n = 4), translation (n = 2), and HRQL measurement (n = 71). 31 reported ethically engaged research. Reports originated primarily from Australia (n = 38), New Zealand (n = 20), USA (n = 9) and Canada (n = 6). Nearly all (n = 73) reported indirect, multi-attribute PBMs, the most common of which was the EQ-5D (n = 50). CONCLUSION: A large number of recent publications from diverse disciplines report the use of PBMs with Indigenous people, despite little evidence on measurement properties in these populations. Understanding the measurement properties of PBMs with Indigenous people is important to better understand how these measures might, or might not, be used in policy and resource decisions affecting Indigenous people.

PURPOSE: Ureteral stone impaction is associated with unfavorable endourological outcomes; however, reliable predictors of stone impaction are limited. We aimed to assess the performance of ureteral wall thickness on noncontrast computed tomography as a predictor of ureteral stone impaction and failure rates of spontaneous stone passage, shock wave lithotripsy, and retrograde guidewire and stent passage. MATERIALS AND METHODS: This study was completed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. A search was conducted in April 2022 for all adult, human, and English language studies investigating ureteral wall thickness using PROSPERO, OVID Medline, OVID EMBASE, Wiley Cochrane Library, Proquest Dissertations & Theses Global, and SCOPUS. A systematic review and meta-analysis using random effects model was conducted. Risk of bias was assessed using the MINORS (Methodological Index for Non-randomized Studies) score. RESULTS: Fourteen studies with a pooled population of 2,987 patients were included for quantitative analysis, and 34 studies were included in our qualitative review. Meta-analysis findings suggest that a thinner ureteral wall thickness is associated with more favorable subgroup stone outcomes. Thinner ureteral wall thickness suggests a lack of stone impaction and was associated with improved rates of spontaneous stone passage, successful retrograde guidewire and stent placement, and improved shock wave lithotripsy outcomes. Studies lack a standardized ureteral wall thickness measurement protocol. CONCLUSIONS: Ureteral wall thickness is a noninvasive measure that predicts ureteral stone impaction, and thin measurements are predictive of successful outcomes. Variability in measurement methods confirms that a standardized ureteral wall thickness protocol is needed, and the clinical utility of ureteral wall thickness is yet to be determined.

BACKGROUND: Modern breast surgical oncology incorporates many aspects of care including preoperative workup, surgical management, and multidisciplinary collaboration to achieve favorable oncologic outcomes and high patient satisfaction. However, there is variability in surgical practice and outcomes. This review aims to identify modifiable surgeon factors influencing breast surgery outcomes and provide a definition of the modern breast surgical oncologist. METHODS: A systematic literature search with additional backward citation searching was conducted. Studies describing modifiable surgeon factors with associated breast surgery outcomes such as rates of breast conservation, sentinel node biopsy, re-excision, complications, acceptable esthetic outcome, and disease-free and overall survival were included. Surgeon factors were categorized for qualitative analysis. RESULTS: A total of 91 studies met inclusion criteria describing both modifiable surgeon factor and outcome data. Four key surgeon factors associated with improved breast surgery outcomes were identified: surgical volume (45 studies), use of oncoplastic techniques (41 studies), sub-specialization in breast surgery or surgical oncology (9 studies), and participation in professional development activities (5 studies). CONCLUSIONS: On the basis of the literature review, the modern breast surgical oncologist has a moderate- to high-volume breast surgery practice, understands the use and application of oncoplastic breast surgery, engages in additional training opportunities, maintains memberships in relevant societies, and remains up to date on key literature. Surgeons practicing in breast surgical oncology can target these modifiable factors for professional development and quality improvement.

Superior vena cava (SVC) flow has been considered a surrogate marker of systemic blood flow in neonates. We conducted a systematic review to evaluate the association between low SVC flow recorded during the early neonatal period and neonatal outcomes. We searched the following databases (until December 9, 2020; updated October 21, 2022): PROSPERO, OVID Medline, OVID EMBASE, Cochrane Library (CDSR and Central), Proquest Dissertations and Theses Global, and SCOPUS using controlled vocabulary and key words representing the concepts "superior vena cava" and "flow" and "neonate." Results were exported to COVIDENCE review management software. The search retrieved 593 records after the removal of duplicates, of which 11 studies (nine cohorts) met the inclusion criteria. The majority of the studies included infants born at <30 weeks of gestation. The included studies were assessed as high risk of bias in terms of the incomparability of the study groups, with infants in the low SVC flow group noted to be more immature than those in the normal SVC flow group or subjected to different cointerventions. We did not conduct meta-analyses in view of the significant clinical heterogeneity noted in the included studies. We found little evidence to suggest that SVC flow in the early neonatal period is an independent predictor for adverse clinical outcomes in preterm infants. Included studies were assessed at high risk of bias. We conclude that SVC flow interpretation for prognostication or for making treatment decisions should be restricted to the research setting for now. We highlight the need for strengthened methods in future research studies. KEY POINTS: · We studied whether low SVC flow in the early neonatal period is a marker for adverse outcomes in preterm infants.. · There is insufficient evidence to conclude that low SVC flow is a valid predictor of adverse outcomes.. · There is insufficient evidence to conclude that SVC flow-directed hemodynamic management improves clinical outcomes..
RESUMO
Objectives: Acetaminophen has gained interest in the neonatal community for its use in the management of hemodynamically significant patent ductus arteriosus (HsPDA) in preterm infants. We conducted a systematic review of randomized controlled trials (RCTs) comparing the efficacy and safety of acetaminophen with indomethacin for the management of HsPDA in preterm infants. Methods: We searched PROSPERO, OVID Medline, OVID EMBASE, Wiley Cochrane Library (CDSR and Central), EBSCO CINAHL, and SCOPUS from inception to June 15, 2021. Bibliographies of identified studies were searched for additional references. Data were analyzed with Review Manager (RevMan) Version 5.3. Results: Four RCTs were identified, enrolling a total of 380 subjects. There was no difference between the interventions for the outcome of PDA closure after one course (RR 1.04 [95% CIs: 0.84, 1.29], P-value 0.70) or after two courses of treatment (RR 1.01 [95% CIs: 0.92, 1.12], P-value 0.77); and for the outcome of PDA ligation (RR 1.56 [95% CIs: 0.48, 5.12], P-value 0.46). However, patients who received acetaminophen had lower rates of necrotizing enterocolitis (RR 0.37 [95% CIs: 0.14, 0.95], P-value 0.04). There were no significant differences noted in the other clinical outcomes, that is, intraventricular hemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity requiring treatment, and death. Two studies noted significant post-treatment elevation of serum creatinine and blood urea with indomethacin, as compared to none with acetaminophen use. Conclusions: Acetaminophen has comparable efficacy to indomethacin for the outcome of HsPDA closure, with a better safety profile, that is, lesser rates of necrotizing enterocolitis and post-treatment azotemia noted with its use.
RESUMO
PURPOSE: Oral nutritional supplements and fortified foods, here considered supplemented food products (SFP), are recommended as part of nutrition therapy guidelines to treat malnutrition among cancer patients. However, their successful use is limited by patients' failure to meet recommended intakes. This systematic review aimed to identify sensory preferences for SFP among cancer patients and evaluate the methodologies employed in sensory preference assessment. METHODS: A systematic search was conducted in several relevant databases yielding 1056 papers of which 19 met the inclusion criteria. Two authors independently selected papers and extracted findings. The included papers were categorized according to the focus of the preference assessment. RESULTS: Studies comparing sensory preferences for SFP of cancer patients with those of a control group suggested that the liking for SFP by cancer patients differs from healthy participants. Patient heterogeneity in site and stage of tumor, variation in study methodologies, and type of treatment complicated a conclusion regarding the effects of cancer treatment and taste changes on taste preferences. However, some general results were observed among the studies, such as the preference for fresh milk-based supplements when compared with other supplement types. CONCLUSION: This review highlighted the need for consistent reporting and control of variables that influence the sensory characteristics of SFP when sensory preferences are assessed in the clinical setting. Attention to these methodological details will enhance the reliability and accuracy of sensory preference assessment among cancer patients for realistic evaluation of SFP targeted to their nutritional needs.

Objectives: Type one diabetes (T1D) in children places substantial responsibility on parents as caregivers. This study investigated caregiver burden in parents of children with T1D by exploring the financial, physical, social, spiritual, and emotional or psychological problems they experienced. Methods: We conducted a qualitative scoping review of the databases PsycINFO, PROSPERO, OVID Medline, OVID EMBASE, Cochrane Library (CDSR and Central), EBSCO CINAHL, ProQuest Dissertations and Theses Global, and SCOPUS. Of 119 full text articles assessed for eligibility, 18 peer-reviewed qualitative studies were included. Studies were considered relevant if they focused on diabetes management and parental burden or the experience of caregiving for a child with T1D. Results: Using thematic analysis, six interrelated themes were identified: (a) experiencing chronic sorrow, (b) assuming responsibility for glucose highs and lows, (c) managing T1D and nighttime sleep disturbances, (d) making career sacrifices and choices to optimize T1D care, (e) navigating social experiences postdiagnosis, and (f) discovering new sources of support through online platforms. Conclusions: This synthesis highlights an all-encompassing experience involved in caretaking for a child with T1D. Caregiving duties lead to a constant sense of vigilance, especially due to fear of hypoglycemic incidents. Parents commonly experience challenges with balancing work demands with T1D management, which lead to career and financial sacrifices. Their burden of care is exacerbated by a lack of reliable respite care but helped somewhat by online peer support. Future research is needed on the care burden differences between mothers and fathers and how sociodemographic factors affect how caregiver burden is experienced.
RESUMO
BACKGROUND: The Global increase in colonization by multidrug-resistant (MDR) bacteria poses a significant concern. The precise impact of MDR colonization in solid organ transplant recipients (SOTR) remains not well established. OBJECTIVES: To assess the impact of MDR colonization on SOTR's mortality, infection, or graft loss. METHODS AND DATA SOURCES: Data from PROSPERO, OVID Medline, OVID EMBASE, Wiley Cochrane Library, ProQuest Dissertations, Theses Global, and SCOPUS were systematically reviewed, spanning from inception until 20 March 2023. The study protocol was registered with PROSPERO (CRD42022290011) and followed the PRISMA guidelines. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, INTERVENTIONS, AND ASSESSMENT OF RISK OF BIAS: Cohorts and case-control studies that reported on adult SOTR colonized by Methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), extended-spectrum ß-lactamase (ESBL) or carbapenem-resistant Enterobacteriaceae. (CRE), or MDR-pseudomonas, and compared to noncolonized, were included. Two reviewers assessed eligibility, conducted a risk of bias evaluation using the Newcastle-Ottawa Scale, and rated certainty of evidence using the GRADE approach. METHODS OF DATA SYNTHESIS: We employed RevMan for a meta-analysis, using random-effects models to compute pooled odds ratios (OR) and 95% confidence intervals (CI). Statistical heterogeneity was determined using the I2 statistic. RESULTS: 15,202 SOTR (33 cohort, six case-control studies) were included, where liver transplant and VRE colonization (25 and 14 studies) were predominant. MDR colonization significantly increased posttransplant 1-year mortality (OR, 2.35; 95% CI, 1.63-3.38) and mixed infections (OR, 10.74; 95% CI, 7.56-12.26) across transplant types (p < 0.001 and I2 = 58%), but no detected impact on graft loss (p 0.41, I2 = 0). Subgroup analysis indicated a higher association between CRE or ESBL colonization with outcomes (CRE: death OR, 3.94; mixed infections OR, 24.8; ESBL: mixed infections OR, 10.3; no mortality data) compared to MRSA (Death: OR, 2.25; mixed infection: OR, 7.75) or VRE colonization (Death: p 0.20, mixed infections: OR, 5.71). CONCLUSIONS: MDR colonization in SOTR, particularly CRE, is associated with increased mortality. Despite the low certainty of the evidence, actions to prevent MDR colonization in transplant candidates are warranted.
RESUMO
INTRODUCTION: Competency-based training requires frequent assessment of residents' skills to determine clinical competence. This study reviews existing literature on procedure-specific competence assessment tools in orthopaedic surgery. METHODS: A systematic search of eight databases up to May 2023 was conducted. Two reviewers independently assessed validity evidence and educational utility of each assessment tool and evaluated studies' methodological quality. RESULTS: Database searching identified 2,556 unique studies for title and abstract screening. Full texts of 290 studies were reviewed; 17 studies met the inclusion criteria. Bibliography review identified another five studies, totaling 22 studies examining 24 assessment tools included in the analysis. These tools assessed various orthopaedic surgery procedures within trauma, sports medicine, spine, and upper extremity. Overall validity evidence was low across all studies, and was lowest for consequences and highest for content. Methodological quality of studies was moderate. Educational utility assessment was not explicitly done for most tools. DISCUSSION: The paucity of current procedure-specific assessment tools in orthopaedic surgery lacks the validity evidence required to be used reliably in high-stake summative assessments. Study strengths include robust methodology and use of an evidence-based validity evidence framework. Poor-quality existing evidence is a limitation and highlights the need for evidence-based tools across more subspecialties.

OBJECTIVES: We aim to investigate the implementation of Target Trial Emulation (TTE) for causal inference, involving research topics, frequently used strategies, and issues indicating the need for future improvements. STUDY DESIGN AND SETTING: We performed a scoping review by following the Joanna Briggs Institute (JBI) guidance and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. A health research-focused librarian searched multiple medical databases, and two independent reviewers completed screening and extraction within covidence review management software. RESULTS: Our search resulted in 1,240 papers, of which 96 papers were eligible for data extraction. Results show a significant increase in the use of TTE in 2018 and 2021. The study topics varied and focused primarily on cancer, cardiovascular and cerebrovascular diseases, and infectious diseases. However, not all papers specified well all three critical components for generating robust causal evidence: time-zero, random assignment simulation, and comparison strategy. Some common issues were observed from retrieved papers, and key limitations include residual confounding, limited generalizability, and a lack of reporting guidance that need to be improved. CONCLUSION: Uneven adherence to the TTE framework exists, and future improvements are needed to progress applications using causal inference with observational data.

BACKGROUND: Cytolytic vaginosis (CV) is a little-known, controversial condition that is typically not considered for women presenting with vulvovaginitis symptoms. Objective: The objective of this scoping review was to identify and compile the global evidence on CV. METHODS: A medical librarian searched Prospero, Wiley Cochrane Library, Ovid Embase, Ovid Medline, EBSCO CINAHL, ProQuest Dissertations and Theses Global, and Scopus, from inception to April 4, 2019 and updated to October 17, 2021. Studies were eligible if they discussed CV. Two independent reviewers conducted study selection and data extraction. RESULTS: Sixty-four studies were identified, with 67% of studies (n = 43) published since 2007. Studies were from around the world, including the United States (28%, n = 18), Brazil (11%, n = 7), Portugal (11%, n = 7), and China (11%, n = 7). Fifty percent of studies (n = 32) were reviews; the remainder were observational; and of these, 78% (n = 25) were cross-sectional. The most frequent topics included: diagnosis (19%, n = 12), prevalence (17%, n = 11), and overview of CV (50%, n = 32). Evidence for prevalence in symptomatic women (median prevalence of 5%, interquartile range 3%-8%) was based only on 16% of studies (n = 10) with minimal evidence on prevalence in asymptomatic women and across different geographic regions. Microbiological findings, including abundant lactobacilli and fragmented epithelial cells, were found useful to distinguish between CV and vulvovaginal candidiasis, and Lactobacillus crispatus was noted to dominate the vaginal flora in women with CV. Most studies used subjective criteria to diagnose CV as the condition lacks gold-standard microscopic criteria. The suggested primary treatment (baking soda irrigations) was largely based on expert opinion, and there was minimal evidence on associations between CV and other conditions. CONCLUSION: Knowledge gaps currently exist in all realms of CV research. Additional research is needed to confirm the validity of CV and ensure that women are diagnosed and treated effectively.

BACKGROUND: Long-term noninvasive positive airway pressure (PAP) treatment is effective treatment for sleep-related breathing disorders and chronic hypercarbic respiratory failure secondary to chronic obstructive pulmonary disease (COPD). PAP treatment may be delivered as continuous positive airway pressure or noninvasive ventilation. Success in initiating PAP treatment and barriers to its use in adult patients with COPD are largely unknown. This systematic review aims to identify the acceptance of and adherence to PAP treatment prescribed for long-term use in adult patients with COPD and to summarize variables associated with these measures. METHODS: Seven online electronic databases will be searched by an experienced medical librarian to identify records containing the concepts "obstructive airways disease" and "noninvasive positive airway pressure" and "acceptance" or "adherence". Randomized and non-randomized studies of interventions will be included. Citation lists from relevant articles will be reviewed, and experts will be contacted regarding unpublished studies. Abstracts from key conferences between 2018-2023 and Google Scholar search results will be reviewed for inclusion. Titles, abstracts and full texts will be reviewed independently for inclusion by two reviewers. Data extraction will be completed by one author using a pre-established form and primary outcomes confirmed by a second author. Methodological quality will be evaluated. If sufficient data are available for meta-analysis, a pooled summary statistic for the primary outcome will be calculated using a random-effects generic inverse-variance meta-analysis, weighted proportion or weighted medians-based approach. Subgroup analysis will explore clinically meaningful sources of heterogeneity. Variables that are associated with acceptance and adherence will be described. DISCUSSION: Long-term PAP treatment is a complex intervention prescribed to patients with COPD for several indications. Synthesis of the evidence on success with PAP treatment and variables associated with acceptance or adherence will inform program and policy development for supporting patients with COPD who are prescribed this therapy. TRIAL REGISTRATION: Systematic review registration: This protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on July 13, 2021 (registration number CRD42021259262), with revisions submitted on April 17, 2023.

OBJECTIVE: Nasal septum cartilage is a hyaline cartilage that provides structural support to the nasal cavity and midface. Currently, information on its cellular and mechanical properties is widely dispersed and has often been inferred from studies conducted on other cartilage types such as the knee. A detailed understanding of nasal cartilage properties is important for several biological, clinical, and engineering disciplines. The objectives of this scoping review are to (1) consolidate actual existing knowledge on nasal cartilage properties and (2) identify gaps of knowledge and research questions requiring future investigations. DESIGN: This scoping review incorporated articles identified using PROSPERO, Cochrane Library (CDSR and Central), WOS BIOSIS, WOS Core Collection, and ProQuest Dissertations and Theses Global databases. Following the screening process, 86 articles were considered. Articles were categorized into three groups: growth, extracellular matrix, and mechanical properties. RESULTS: Most articles investigated growth properties followed by extracellular matrix and mechanical properties. NSC cartilage is not uniform. Nasal cartilage growth varies with age and location. Similarly, extracellular matrix composition and mechanical properties are location-specific within the NSC. Moreover, most articles included in the review investigate these properties in isolation and only very few articles demonstrate the interrelationship between multiple cartilage properties. CONCLUSIONS: This scoping review presents a first comprehensive description of research on NSC properties with a focus on NSC growth, extracellular matrix and mechanical properties. It additionally identifies the needs (1) to understand how these various cartilage properties intersect and (2) for more granular, standardized assessment protocols to describe NSC.

In cold temperatures, vehicles idle more, have high cold-start emissions including greenhouse gases, and have less effective exhaust filtration systems, which can cause up to ten-fold more harmful vehicular emissions. Only a few vehicle technologies have been tested for emissions below -7 °C (20 °F). Four-hundred-million people living in cities with sub-zero temperatures may be impacted. We conducted a scoping review to identify the existing knowledge about air-pollution-related health outcomes in a cold climate, and pinpoint any research gaps. Of 1019 papers identified, 76 were selected for review. The papers described short-term health impacts associated with air pollutants. However, most papers removed the possible direct effect of temperature on pollution and health by adjusting for temperature. Only eight papers formally explored the modifying effect of temperatures. Five studies identified how extreme cold and warm temperatures aggravated mortality/morbidity associated with ozone, particles, and carbon-monoxide. The other three found no health associations with tested pollutants and temperature. Additionally, in most papers, emissions could not be attributed solely to traffic. In conclusion, evidence on the relationship between cold temperatures, traffic-related pollution, and related health outcomes is lacking. Therefore, targeted research is required to guide vehicle regulations, assess extreme weather-related risks in the context of climate change, and inform public health interventions.

Background and objectives: Climate change impacts are felt unequally worldwide; populations that experience geographical vulnerability, those living in small island states and densely populated coastal areas, and children and women are affected disproportionately. This scoping review aims to synthesize evidence from relevant studies centred on South Asia, identify research gaps specifically focused on children and women's health, and contribute to knowledge about South Asia's existing mitigation and adaptation strategies. Methods: A research librarian executed the search on six databases using controlled vocabulary (e.g., MeSH, Emtree, etc.) and keywords representing the concepts "vulnerable populations" and "climate change" and "health impacts" and "South Asia." Databases were searched from January 2010 to May 2020. Papers were screened independently by two researchers. Results: Forty-two studies were included, of which 23 were based in India, 14 in Bangladesh, and five in other South Asian countries. Nineteen studies focused on meteorological factors as the primary exposure. In contrast, thirteen focused on extreme weather events, nine on air pollution, and one on salinity in coastal areas. Thirty-four studies focused on the health impacts on children related to extreme weather events, meteorological factors, and air pollution, while only eight studies looked at health impacts on women. Undernutrition, ARI (acute respiratory infection), diarrheal diseases, low birth weight, and premature mortality were the major health impacts attributed to extreme weather events, meteorological factors, and air pollution exposure in children and women in the region. Conclusion: Extreme weather events, meteorological factors and air pollution have affected the health of children and women in South Asia. However, the gap in the literature across the South Asian countries concerning relationships between exposure to extreme weather events, meteorological factors, air pollution and health effects, including mental health problems in children and women, are opportunities for future work.
RESUMO
BACKGROUND: The severity of the COVID-19 pandemic is likely to exacerbate mental health problems during the prenatal period and increase the risk of adverse birth outcomes. This review assessed the published literature related to the impacts of prenatal mental health issues on birth outcomes during the COVID-19 pandemic. METHODS: This scoping review was conducted using PROSPERO, Cochrane Library, OVID Medline, Ovid EMBASE, OVID PsycInfo, EBSCO CINAHL, and SCOPUS. The search was conducted using controlled vocabulary and keywords representing the concepts "COVID19", "mental health" and "birth outcomes". The main inclusion criteria were peer-reviewed published articles from late 2019 to the end of July 2021. RESULTS AND DISCUSSION: After removing duplicates, 642 articles were identified, of which two full texts were included for analysis. Both articles highlighted that pregnant women have experienced increasing prenatal mental health issues during the COVID-19 pandemic and, further, increased the risk of developing adverse births. This scoping review highlighted that there is a lack of research on the impact of prenatal mental health issues on birth outcomes during the pandemic. CONCLUSION: Given the severity of the COVID-19 pandemic and the burdens of prenatal mental health issues and adverse birth outcomes, there is an urgent need to conduct further research.

BACKGROUND AND OBJECTIVE: The relationship between protoporphyrin IX (PpIX) photobleaching and cellular damage during aminolevulinic (ALA) photodynamic therapy (PDT) has been studied at the cellular level. This study assessed the capability of a non-invasive fluorescence imaging system (Dyaderm, Biocam, Germany), to monitor changes in PpIX during real time methyl-aminolevulinate (MAL) PDT in dermatological lesions, and thus to act as a predictive tool in terms of observed clinical outcome post-treatment. MATERIALS AND METHODS: Patients attending Royal Cornwall Hospital (Truro, UK) for MAL-PDT to licensed lesions (actinic keratosis, Bowen's disease, and basal cell carcinoma) were monitored using the pre-validated non-invasive fluorescence imaging system. Patients were imaged at three distinct time points: prior to the application of MAL, after the 3 hours of MAL application and immediately following light irradiation. The fluorescence intensity of the images were analysed with image analysis software and the percentage change in fluorescence during light irradiation was related to the clinical outcome observed 3 months following treatment. In total 100 patients underwent at least one session of MAL-PDT. RESULTS: Significantly higher levels of change in PpIX fluorescence during light irradiation (P<0.005) were observed in lesions undergoing complete clearance at 3 months when compared to those patients who underwent partial or no clearance. In contrast no significant difference (P>0.500) was observed in the total levels of PpIX recorded after MAL application in patients undergoing partial and complete clearance at 3 months. CONCLUSIONS: PpIX photobleaching is indicative of the level of cellular damage PDT treatment will induce and therefore the clinical outcome expected within patients. This study indicated the potential of the commercially available fluorescence imaging system investigated to predict treatment success at the time of light irradiation and in the future it may be possible to employ it to individualise treatment parameters to improve dermatological PDT efficacy/outcome.

BACKGROUND: Dermatological methyl-aminolevulinate photodynamic therapy (MAL-PDT) is utilized to successfully treat dermatological conditions. This study monitored fluorescence changes attributed to the accumulation and destruction of the photosensitizer, protoporphyrin IX (PpIX), at several different stages during the first and second treatments of clinical dermatological MAL-PDT. METHODS: A commercially available, non-invasive, fluorescence imaging system (Dyaderm, Biocam, Germany) was utilized to monitor fluorescence changes during the first and second MAL-PDT treatments in seventy-five lesions. RESULTS: The clinical data indicated statistically significant increases in fluorescence within lesions following the application of MAL for both treatments (P<0.001 and P<0.01 respectively) and subsequent statistically significant decreases in fluorescence within the lesions following light irradiation for both treatments (P<0.001 and P<0.01 respectively) whilst normal skin fluorescence remained unaltered. Lesions receiving a second treatment accumulated and dissipated significantly less PpIX (P<0.05) than during the first treatment. No significant differences were noted in PpIX accumulation or dissipation during MAL-PDT when gender, age, lesion type and lesion surface area were considered. CONCLUSIONS: It can therefore be concluded that PpIX fluorescence imaging can be used in real-time to assess PpIX levels during dermatological PDT. Similar observations were recorded from the three currently licensed indications indicating that the standard 'one size fits all' protocol currently employed appears to allow adequate PpIX accumulation, which is subsequently fully utilized during light irradiation regardless of patient age, gender or lesion surface area.
