Clinical characteristics and aetiology of uveitis in a viral haemorrhagic fever zone.

BACKGROUND/OBJECTIVES: Studies on uveitis in Sierra Leone were conducted prior to the Ebola Virus Disease epidemic of 2013-16, which was associated with uveitis in 20% of survivors. They did not include imaging or investigation of tuberculosis and used laboratory services outside the country. We performed a cross-sectional study on patients presenting with uveitis to establish their clinical characteristics and identify the impact of in-country laboratory diagnoses. METHODS: We invited uveitis cases presenting to Eye Clinics in Sierra Leone from March to September 2022 to participate in the study. They underwent a diagnostic work-up, including fundus and ocular coherence tomography imaging. Active uveitis cases underwent further investigations including serology and immunological tests for syphilis, tuberculosis, herpetic viruses and HIV and chest radiographs. RESULTS: We recruited 128 patients. The median age was 34 (IQR 19) years and there was an equal gender split. Panuveitis was the predominant anatomical uveitis type (n = 51, 40%), followed by posterior uveitis (n = 36, 28%). Bilateral disease affected 40 patients (31%). Active uveitis was identified in 75 (59%) cases. ICD 11 definition of blindness with VA < 3/60 occurred in 55 (33%) uveitis eyes. Aetiology of uveitis from clinical and laboratory assessment demonstrated that most cases were of undifferentiated aetiology (n = 66, 52%), followed by toxoplasmosis (n = 46, 36%). Trauma contributed to eight (6%) cases, syphilis to 5 (4%) cases and Ebola to 2 (2%). CONCLUSIONS: Uveitis was associated with high levels of visual impairment. Posterior and panuveitis contributed to the highest proportion of uveitis cases. Laboratory studies helped differentiate syphilis as a significant aetiology of uveitis.

Advancing Research on and Treatment of Dissociative Identity Disorder With People With Lived Experience.

Dissociative identity disorder is a posttraumatic, psychobiological syndrome that develops over time during childhood. Despite empirical evidence supporting the validity of this diagnosis and its relation to trauma, the disorder remains a misunderstood and stigmatized condition. This article highlights expert consensus guidelines and current empirical research on the treatment of dissociative identity disorder. In addition, the authors describe the Lived Experience Advisory Panel (LEAP), which was designed to leverage the expertise of individuals with dissociative identity disorder to combat stigma and improve research, clinical programming, professional education, and public outreach related to the disorder. This article also describes how LEAP members have partnered with other researchers to create new knowledge through participatory action research in order to advance equitable service provision and effect positive change.

Potential new cancer biomarkers revealed by quantum chemistry associated with bioinformatics in the study of selectin polymorphisms.

Understanding the complex mechanisms involved in diseases caused by or related to important genetic variants has led to the development of clinically useful biomarkers. However, the increasing number of described variants makes it difficult to identify variants worthy of investigation, and poses challenges to their validation. We combined publicly available datasets and open source robust bioinformatics tools with molecular quantum chemistry methods to investigate the involvement of selectins, important molecules in the cell adhesion process that play a fundamental role in the cancer metastasis process. We applied this strategy to investigate single nucleotide variants (SNPs) in the intronic and UTR regions and missense SNPs with amino acid changes in the SELL, SELP, SELE, and SELPLG genes. We then focused on thyroid cancer, seeking these SNPs potential to identify biomarkers for susceptibility, diagnosis, prognosis, and therapeutic targets. We demonstrated that SELL gene polymorphisms rs2229569, rs1131498, rs4987360, rs4987301 and rs2205849; SELE gene polymorphisms rs1534904 and rs5368; rs3917777, rs2205894 and rs2205893 of SELP gene; and rs7138370, rs7300972 and rs2228315 variants of SELPLG gene may produce important alterations in the DNA structure and consequent changes in the morphology and function of the corresponding proteins. In conclusion, we developed a strategy that may save valuable time and resources in future investigations, as we were able to provide a solid foundation for the selection of selectin gene variants that may become important biomarkers and deserve further investigation in cancer patients. Large-scale clinical studies in different ethnic populations and laboratory experiments are needed to validate our results.

Blended intensive programme's implementation in dental education: post-pandemic evolution of learning.

Blended Intensive Programmes (BIP's) represent a valuable tool for gathering knowledge and summarising the latest trends in medicine and dentistry. Blended education has been found, even before the COVID-19 pandemic, to increase the level of education and stimulate effective learning for postgraduate healthcare professionals. Interprofessional education is critical for preparing students to enter the health workforce, where teamwork and collaboration are important competencies. This article outlines the key points of the Blended Intensive Programme's implementation in dental education organised by Wroclaw Medical University in Poland. BIP involved professors from 12 universities or research institutions from Europe and South America and 28 participants from 8 countries. The course was taught remotely and in person. In addition, it included a visit to the university and practical classes with artificial simulation and practice in dentistry. A structured questionnaire enabled measuring the evaluation of students' perception of the COVID-19 education before and after the pandemic. The European Region Action Scheme for the Mobility of University Students (ERASMUS) was fundamental to carrying out the BIP with the participation of several countries, allowing the exchange of knowledge, assessing the impact of the pandemic on dental universities, and strengthening international collaborations and the future project of research, education and clinical assistance. We conclude that hybrid teaching programmes broaden the learning spectrum in dental studies by allowing transnational and interdisciplinary approaches that make students aware of the importance of their work within the framework of the general health approach, as this differs from country to country.

Treatment of dissociative identity disorder: leveraging neurobiology to optimize success.

INTRODUCTION: Dissociative identity disorder (DID) is a treatable mental health condition that is associated with a range of psychobiological manifestations. However, historical controversy, modern day misunderstanding, and lack of professional education have prevented accurate treatment information from reaching most clinicians and patients. These obstacles also have slowed empirical efforts to improve treatment outcomes for people with DID. Emerging neurobiological findings in DID provide essential information that can be used to improve treatment outcomes. AREAS COVERED: In this narrative review, the authors discuss symptom characteristics of DID, including dissociative self-states. Current treatment approaches are described, focusing on empirically supported psychotherapeutic interventions for DID and pharmacological agents targeting dissociative symptoms in other conditions. Neurobiological correlates of DID are reviewed, including recent research aimed at identifying a neural signature of DID. EXPERT OPINION: Now is the time to move beyond historical controversy and focus on improving DID treatment availability and efficacy. Neurobiological findings could optimize treatment by reducing shame, aiding assessment, providing novel interventional brain targets and guiding novel pharmacologic and psychotherapeutic interventions. The inclusion of those with lived experience in the design, planning and interpretation of research investigations is another powerful way to improve health outcomes for those with DID.

Innovative and Effective Education Strategies for Adult Learners in the Perioperative Setting.

Ongoing nursing education is vital for keeping nurses' knowledge and skills current and promoting positive patient outcomes. Providing meaningful, quality nursing education in the perioperative setting requires the development and implementation of innovative and effective teaching strategies. Adult learning theory is complex, and it can be challenging to engage multigenerational perioperative staff members in education-often, a variety of creative teaching modalities are required to bridge the gaps among learning styles. This article reviews the use of experiential learning, various kinesthetic activities, advanced technology, microlearning, and other methods that may be helpful to overcome the challenges of providing education to adult learners in the perioperative setting. Educators should promote critical thinking and student engagement to encourage adult learners to be active participants in their continuing education.

Leveraging Clinical Ladder Nurses to Support an Education Program on Intraoperative Cell Salvage for Obstetric Patients.

Postpartum hemorrhage continues to be a leading cause of maternal morbidity and mortality in the United States. With the use of appropriate screening tools and treatment modalities, most of these deaths are preventable. Various interventions are used to prevent and treat postpartum hemorrhage, though intraoperative cell salvage historically has been contraindicated in the obstetric setting. This article explores the implementation of intraoperative cell salvage in the obstetric setting at two campuses of a health care system with the assistance of nurses participating in a professional nurses advancement program (ie, a clinical ladder). The initiative comprised a literature review, interdisciplinary collaboration, and education planning and execution. The educational approach focused on adult learners and included both self-directed and instructor-led elements. Including clinical nurses in clinical education is beneficial because they are highly motivated to share evidence-based practice with their peers to elevate patient safety and quality measures, making them ideal education partners.

Racial/ethnic and sex differences in the association between light at night and actigraphy-measured sleep duration in adults: NHANES 2011-2014.

OBJECTIVE: Historically minoritized individuals experience greater exposure to light at night, yet it is unclear whether the association between light at night and sleep duration vary by race/ethnicity or sex. We examined the association between light at night and sleep duration by race/ethnicity and sex. METHODS: Participants (N = 6089, mean age=49.5, 52% women, 13% Asian, 27% Black, 14% Mexican, 46% White) in the 2011-2014 National Health and Nutrition Examination Survey underwent 9-day of actigraphy. Light at night was defined as light exposure within the 5-hour activity nadir (L5). Sleep duration within a 24-hour period was analyzed as short (<7 hours) or long (>9 hours) compared to recommended (≥7 and <9 hours). Poisson models were fit to estimate the association between light at night and sleep duration after adjustment for covariates. RESULTS: Light at night was most common among Black participants, who also had the shortest sleep duration. Overall, light at night was associated with 80% higher prevalence of short sleep duration [1.80 (1.49, 2.18)]. Compared to no-light at night, low and high light at night were associated with higher prevalence of short sleep duration, [1.61 (1.31, 1.98) and 2.01 (1.66, 2.44), respectively]. Associations varied by race/ethnicity and sex. Light at night was associated with shorter sleep duration in Black, Mexican and White females and Mexican and White males only. Black males exposed to light at night vs. no-light at night had lower prevalence of long sleep duration. There were no associations between light at night and sleep duration among Asian participants. CONCLUSION: Light at night was associated with shorter sleep duration, particularly among females. Targeting light exposure may help to improve sleep duration.

Clinical and molecular impact of concurrent thyroid autoimmune disease and thyroid cancer: From the bench to bedside.

The recent incorporation of immune checkpoint inhibitors targeting the PD-1 (programmed cell death receptor 1) and CTLA-4 (cytotoxic T lymphocyte antigen 4) pathways into the therapeutic armamentarium of cancer has increased the need to understand the correlation between the immune system, autoimmunity, and malignant neoplasms. Both autoimmune thyroid diseases and thyroid cancer are common clinical conditions. The molecular pathology of autoimmune thyroid diseases is characterized by the important impact of the PD-1/PD-L1 axis, an important inhibitory pathway involved in the regulation of T-cell responses. Insufficient inhibitory pathways may prone the thyroid tissue to a self-destructive immune response that leads to hypothyroidism. On the other hand, the PD-1/PD-L1 axis and other co-inhibitory pathways are the cornerstones of the immune escape mechanisms in thyroid cancer, which is a mechanism through which the immune response fails to recognize and eradicate thyroid tumor cells. This common mechanism raises the idea that thyroid autoimmunity and thyroid cancer may be opposite sides of the same coin, meaning that both conditions share similar molecular signatures. When associated with thyroid autoimmunity, thyroid cancer may have a less aggressive presentation, even though the molecular explanation of this clinical consequence is unclear. More studies are warranted to elucidate the molecular link between thyroid autoimmune disease and thyroid cancer. The prognostic impact that thyroid autoimmune disease, especially chronic lymphocytic thyroiditis, may exert on thyroid cancer raises important insights that can help physicians to better individualize the management of patients with thyroid cancer.

Understanding covid-19 outcomes among people with intellectual disabilities in England.

BACKGROUND: Evidence from the UK from the early stages of the covid-19 pandemic showed that people with Intellectual Disabilities (ID) had higher rates of covid-19 mortality than people without ID. However, estimates of the magnitude of risk vary widely; different studies used different time periods; and only early stages of the pandemic have been analysed. Existing analyses of risk factors have also been limited. The objective of this study was to investigate covid-19 mortality rates, hospitalisation rates, and risk factors in people with ID in England up to the end of 2021. METHODS: Retrospective cohort study of all people with a laboratory-confirmed SARS-CoV-2 infection or death involving covid-19. Datasets covering primary care, secondary care, covid-19 tests and vaccinations, prescriptions, and deaths were linked at individual level. RESULTS: Covid-19 carries a disproportionately higher risk of death for people with ID, above their already higher risk of dying from other causes, in comparison to those without ID. Around 2,000 people with ID had a death involving covid-19 in England up to the end of 2021; approximately 1 in 180. The covid-19 standardized mortality ratio was 5.6 [95% CI 5.4, 5.9]. People with ID were also more likely to be hospitalised for covid-19 than people without ID. The main determinants of severe covid-19 outcomes (deaths and/or hospitalisations) in both populations were age, multimorbidity and vaccination status. The key factor responsible for the higher risk of severe covid-19 in the ID population was a much higher prevalence of multimorbidity in this population. AstraZeneca vaccine was slightly less effective in preventing severe covid-19 outcomes among people with ID than among people without ID. CONCLUSIONS: People with ID should be considered a priority group in future pandemics, such as shielding and vaccinations.

Examining the Role of Women, Infant, and Children in Black Women Breastfeeding Duration and Exclusivity: A Systematic Review.

Background: African American women continue to experience low rates of breastfeeding initiation as well as low rates of exclusive breastfeeding for 6 months. Research has indicated that there are several social determinants that impact breastfeeding rates, but there is a dearth of literature that allows African American women to give voice to their experiences. In addition, research has shown women, infant, and children (WIC) participants to have lower breastfeeding rates than non-WIC eligible women. Research Aim/Question: The aim of this systematic review was to examine the relationship between WIC program participation and breastfeeding initiation and duration among non-Hispanic African American/Black women. Methods: The approach for this review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Four online databases, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, MEDLINE, and SCOPUS, were used to search for peer-reviewed articles and grey literature. Results: Two hundred eighteen articles were retrieved through the database search and underwent initial screening, yielding 59 potential eligible articles. Full-text articles were further reviewed and 11 met the inclusion criteria and were included in this systematic review. Conclusions: Included studies show mixed results regarding the association between WIC participation and breastfeeding initiation, but there is a general negative association between WIC participation and breastfeeding duration, especially among Black women.

Posterior and panuveitis contributed to the highest proportion of uveitis cases. Laboratory studies helped differentiate syphilis as a significant aetiology of uveitis.

A quality improvement project to increase breast milk feeding of hospitalized late preterm infants in China.

BACKGROUND: The breastfeeding rates of late preterm infants are lower than both term and extremely preterm infants. To explore the interventions of increasing full breast milk feeding rate of hospitalized late preterm infants on the 7th day after birth (D7) and evaluate the effect of these quality improvement (QI) interventions. METHODS: The full breast milk feeding (amount of enteral breast milk reached 120ml/kg/d on D7) rate of hospitalized late preterm infants during May 2017 and November 2017 was set as the baseline before intervention, and the specific aim of promoting breast milk feeding was put forward. The Pareto Chart was used to analyze the factors that affect breast milk feeding process, as well as the discussion of multidisciplinary experts. Key drivers were constructed, including informational materials and education about breast milk feeding, consultations and support on optimal breast milk initiation, initiating breast milk expression within one hour after birth, accurate measurement and recording of expressed breast milk, stimulating continuous and effective lactation, proper breast pump selection in and out of hospital and sending and preserving of expressed milk to NICU. Control chart was used to monitor the monthly change of full breast milk feeding rate until the aim was achieved and sustained. RESULTS: The baseline of full breast milk feeding rate of late preterm infants was 10%, and the aim of QI was to increase the rate to 60% within a two-year period. Control chart dynamically showed the full breast milk feeding rate increased to 80% with the implementation of the interventions, achieved and made the aim of QI sustained. CONCLUSION: QI interventions including breast milk feeding education, early postpartum breast milk pumping, kangaroo care to stimulate breast milk secretion, and convenient way of transporting breast milk to NICU, could significantly improve the full breast milk feeding rate of hospitalized late preterm infants.

Controversies and Conundrums in Newborn Feeding.

Breastfeeding is the biologic norm for newborn feeding, and exclusive breastfeeding for the first 6 months of life is universally endorsed by leading global and national organizations. Despite these recommendations, many people do not meet their breastfeeding goals and controversies surrounding breastfeeding problems exist. Medical issues can present challenges for the clinician and parents to successfully meet desired feeding outcomes. There are studies evaluating these common controversies and medical conundrums, and clinicians should provide evidence-based recommendations when counseling families about newborn feeding.

ABVENTURE-P pilot trial of physical therapy versus standard of care following ventral hernia repair: Protocol for a randomized controlled trial.

Hernia disease is one of the most common reasons patients seek surgical treatment, yet nearly 1 in 4 patients seeking ventral hernia repair in the United States suffer from chronic pain, disability, and diminished physical activity. The relationships between the anterior abdominal wall, lower back, diaphragm, and pelvic floor are critical in providing function and quality of life, yet management of hernia disease has been limited to surgical restoration of anatomy without taking into consideration the functional relationships of the abdominal core. Therefore, the primary goal of this study is to evaluate the feasibility of implementing physical therapy targeted to improving stability and function in this population. A secondary goal is to estimate whether pre-operative abdominal core function predicts responsiveness to physical therapy. This study is a registry-based randomized controlled trial (NCT05142618: Pilot Trial of Abdominal Core Rehabilitation To Improve Outcomes After Ventral Hernia Repair (ABVENTURE-P)). All participants will be randomized to one of two post-operative treatment arms: standard of care plus up to 16 sessions of physical therapy, or standard of care alone. Primary timepoints include pre-operative (baseline) and ten weeks after surgery, with intermediate or secondary timepoints 30 days, 6 months, and 1 year post-operative. At each timepoint, participants will undergo functional and patient-reported outcome testing. We will also collect data on retention rate and treatment adherence. An intention to treat approach is planned for all analyses, using all participants who were randomized and have available data at the 10-week timepoint. This is a pilot and feasibility trial, hence our goals are to establish safety and initial efficacy of the PT intervention, retention and adherence to both PT and control arms, whether pre-operative abdominal core function predicts responsiveness to PT, and to collect a large enough sample to power a future definitive multi-center randomized controlled trial.

NR3C1 rs6198 Variant May Be Involved in the Relationship of Graves' Disease with Stressful Events.

Although stressful events are known to trigger Graves' disease (GD), the mechanisms involved in this process are not well understood. The NR3C1 gene, encoding for the glucocorticoid receptor (GR), presents single nucleotide polymorphisms (SNPs) that are associated with stress-related diseases. To investigate the relationship between NR3C1 SNPs, GD susceptibility, and clinical features, we studied 792 individuals, including 384 patients, among which 209 presented with Graves' orbitopathy (GO), and 408 paired healthy controls. Stressful life events were evaluated in a subset of 59 patients and 66 controls using the IES-R self-report questionnaire. SNPs rs104893913, rs104893909, and rs104893911 appeared at low frequencies and presented similar profiles in patients and controls. However, variant forms of rs6198 were rarer in GD patients, suggesting a protective effect. Stressful events were more common in patients than controls, and were reported to have clearly occurred immediately before the onset of GD symptoms in 23 cases. However, no association was found between these events and rs6198 genotypes or GD/GO characteristics. We suggest that the NR3C1 rs6198 polymorphism may be an important protective factor against GD, but its relationship with stressful events needs further investigation.

Investigation of the clinical utility of adhesion molecules in the management of thyroid nodules.

To better understand the relationship among cell adhesion molecules (CAM) and investigate the clinical diagnostic and prognostic application of ICAM-1 (ICAM1), LFA-1 (ITGAL), and L-selectin (SELL) proteins and mRNA corresponding expression in thyroid cancer. Gene expression was evaluated by RT-qPCR, and protein expression was evaluated by immunohistochemistry. We evaluated 275 patients (218 women, 57 men, 48.4 ± 14.5 years old), including 102 benign and 173 malignant nodules. The 143 papillary thyroid carcinoma (PTC) and 30 follicular thyroid carcinoma (FTC) patients were managed according to current guidelines and followed-up for 78.7 ± 54.2 months. Malignant and benign nodules differed concerning mRNA (p = 0.0027) and protein (p = 0.0020 for nuclear) expression of L-selectin and ICAM-1 (mRNA: p = 0.0001 and protein: p = 0.0014) and protein expression of LFA-1 (p = 0.0168), but not mRNA expression of LFA-1 (p = 0.2131). SELL expression was more intense in malignant tumors (p = 0.0027). ICAM1 (p = 0.0064) and ITGAL (p = 0.0244) mRNA expression was higher in tumors with lymphocyte infiltrate. ICAM-1 expression correlated with younger age at diagnosis (p = 0.0312) and smaller tumor size (p = 0.0443). Also, LFA-1 expression correlated with higher age at diagnosis (p = 0.0376) and was more intense at stage III and IV (p = 0.0077). In general, the protein expression of the 3 CAM decreased as the process of cellular dedifferentiation occurred. We suggest that the SELL and ICAM1 genes and L-selectin and LFA-1 protein expression may help confirm malignancy and assist in the histological characterization of follicular patterned lesions, but we were unable to correlate these CAMs with patient outcomes.

Standardizing Feeding Strategies in Moderately Preterm Infants.

Objective: To evaluate the impact of a standardized feeding protocol and donor breast milk (DBM) provision on clinical outcomes in moderate preterm infants (MPT, 29-33 6/7 weeks gestational age). Study Design: A protocol for MPT infants born > 1500 g was implemented clinically to standardize feeding advancements at 30 mL/kg/day. Infants < 33 weeks received DBM. We retrospectively identified 131 and 144 infants born before and after implementation. Clinical data including central venous line (CVL) placement, feeding tolerance, growth, and provision of maternal breast milk (MBM) were collected. Result: Number of CVLs, days to full enteral volume (FEV), and MBM provision was unchanged. There was a narrower range of days to FEV post-implementation. Growth metrics were similar between eras. Conclusion: Implementation of a feeding protocol for MPT infants is associated with more consistent time to FEV With monitoring and appropriate fortification, DBM use in this population is not associated with worse growth outcomes.

Visual Morbidity and Outcomes of Scleritis Associated with Intraocular Inflammation Compared to Isolated Scleritis.

PURPOSE: To compare visual outcomes, ocular complications and therapies for patients with scleritis-associated intraocular inflammation (SAI) and patients with isolated scleritis (IS). RESULTS: A total of 52 patients (36 with SAI and 16 with IS) were reviewed. Mean age (standard deviation) at presentation was 48.4 years old (± 15.4) in the SAI group and 53 years old (± 17.1) in the IS group (p = .37). Visual acuity was worse at presentation and last visit for patients with SAI compared to IS (p = .04). Patients in the SAI group developed greater posterior segment complications than in the IS group (p = .002). CONCLUSIONS: Scleritis with intraocular inflammation was associated with a higher rate of visual morbidity compared to isolated scleritis. More aggressive management strategies may be needed for patients who present with scleritis associated with inflammation.
