Treatment of iron overload syndrome: a general review.

INTRODUCTION Iron overload is a broad syndrome with a large spectrum of causative etiologies that lead to iron deposition. When iron exceeds defenses, it causes oxidative damage and tissular disfunction. Treatment may prevent organ dysfunction, leading to greater life expectancy. METHODS Literature from the last five years was reviewed through the use of the PubMed database in search of treatment strategies. DISCUSSION Different pharmacological and non-pharmacological strategies are available for the treatment of iron overload and must be used according to etiology and patient compliance. Therapeutic phlebotomy is the basis for the treatment of hereditary hemochromatosis. Transfusional overload patients and those who cannot tolerate phlebotomy need iron chelators. CONCLUSION Advances in the understanding of iron overload have lead to great advances in therapies and new pharmacological targets. Research has lead to better compliance with the use of oral chelators and less toxic drugs.
Invasive Lobular Carcinoma With Extensive Clear Cells: A Pitfall in Diagnosis

Carcinomas in the breast with a predominantly clear cytoplasm are rare. In this article, we review the differential diagnosis of clear cell breast neoplasms and report a case of invasive lobular carcinoma with extensive clear cell morphology that was diagnosed as invasive ductal carcinoma, not otherwise specified, on ultrasound-guided biopsy. Lobular carcinomas with extensive clear cell change are unusual, but must be considered when evaluating a clear cell neoplasm in the breast.
Anti-Oxidized LDL Antibodies and Coronary Artery Disease: A Systematic Review

Antibodies to oxidized LDL (oxLDL) may be associated with improved outcomes in cardiovascular disease. However, analysis is restricted by heterogenous study design and endpoints. Our objective was to conduct a comprehensive systematic review assessing anti-oxLDL antibodies in relation to coronary artery disease (CAD). Through a systematic literature search, we identified all studies assessing the relationship of either, IgG or IgM ox-LDL/ copper-oxLDL/ malondialdehyde-LDL, with coronary atherosclerosis or cardiovascular events in populations with, and without, established CAD. Systematic review best practices were adhered to and study quality was assessed. An initial electronic database search identified 2059 records, which was subsequently followed by abstract and full-text review. Finally, we included 18 studies with over 1811 patients with CAD. The studies varied according to populations studied, conventional cardiovascular risk factors and interventional modalities used to assess CAD. IgM anti-oxLDL antibodies were found to indicate protection from more severe CAD and possibly cardiovascular events, whilst the relationship with IgG is more complex and difficult to elucidate, with studies reporting divergent results. In this systematic review, there is evidence that suggests a relationship between anti-oxLDL antibodies and CAD, especially for the IgM subclass. However, further studies, with well-characterized prospective cohorts, will be important to clarify these associations.
The Effect of a Community Based Educational Intervention on Oral Health Knowledge Levels of Adult Caregivers of Young Children in the Rural Upper Peninsula of Michigan

ABSTRACT Low levels of oral health literacy in parents and caregivers may place a child at risk for poor oral health (Miller, Lee, DeWalt, & Vann, 2010). The purpose of this project was to determine baseline oral health literacy levels for a sample of adult caregivers of young children living in rural communities and to determine the effectiveness of a community-based education program on increasing these baseline levels of knowledge. A convenience sample of sixty-four participants who attended educational programs aimed at adult caregivers of young children comprised the sample. The Upper Peninsula Oral Health Literacy Assessment Survey was administered prior to and after participants attended the educational programming. A paired sample t-test was utilized to analyze the data. There was a statistically significant increase in oral health literacy levels after the implementation of a community-based educational program. Scores reflecting oral health literacy rose from 68.8% on the pre-test to 92.6% on the post-test. This study confirms a need for further oral health education. Increasing oral health literacy levels in adult caregivers of young children may lead to an increase in oral health seeking behaviors and a decrease in preventable dental caries in the pediatric population.
Participation in social/lifestyle activities in people with multiple sclerosis: Changes across 10 years and predictors of sustained participation

Background: Identification of people with multiple sclerosis (PwMS) with increased risk of restricted participation in social and lifestyle activities (e.g. social outings and pursuing a hobby) could guide the development of interventions supporting sustained participation. Objective: To explore changes in participation in complex and social everyday activities over 10 years in PwMS in relation to multiple sclerosis (MS) severity and to identify predictors of sustained participation. Methods: This study was based on a 10-year follow-up of 264 PwMS living in Stockholm County, Sweden. Ten-year changes in participation in social/lifestyle activities were assessed and compared between PwMS with different MS severity with the Frenchay Activities Index using age- and sex-related normative values. Multiple logistic regression analyses were used to predict sustained participation at 10 years using personal factors, disease severity and functioning as independent variables. Results: While a majority of people with mild MS demonstrated sustained participation (67%), a minority of PwMS moderately (26%) and severely affected by MS (5%) demonstrated sustained participation. Significant predictors of sustained participation after 10 years were walking speed ⩾1.2 m/s and ⩾32 correct responses on the Symbol Digit Modalities Test. Conclusion: Our findings accentuate the importance for health services to support mobility and cognition to obtain sustained participation.
Divergent effects of translation termination factor eRF3A and nonsense-mediated mRNA decay factor UPF1 on the expression of uORF carrying mRNAs and ribosome protein genes

ABSTRACT In addition to its role in translation termination, eRF3A has been implicated in the nonsense-mediated mRNA decay (NMD) pathway through its interaction with UPF1. NMD is a RNA quality control mechanism, which detects and degrades aberrant mRNAs as well as some normal transcripts including those that harbour upstream open reading frames in their 5ʹ leader sequence. In this study, we used RNA-sequencing and ribosome profiling to perform a genome wide analysis of the effect of either eRF3A or UPF1 depletion in human cells. Our bioinformatics analyses allow to delineate the features of the transcripts controlled by eRF3A and UPF1 and to compare the effect of each of these factors on gene expression. We find that eRF3A and UPF1 have very different impacts on the human transcriptome, less than 250 transcripts being targeted by both factors. We show that eRF3A depletion globally derepresses the expression of mRNAs containing translated uORFs while UPF1 knockdown derepresses only the mRNAs harbouring uORFs with an AUG codon in an optimal context for translation initiation. Finally, we also find that eRF3A and UPF1 have opposite effects on ribosome protein gene expression. Together, our results provide important elements for understanding the impact of translation termination and NMD on the human transcriptome and reveal novel determinants of ribosome biogenesis regulation.
Minimally Invasive AC Joint Reconstruction System (MINAR®) in Modified Triple-Button Technique for the Treatment of Acute AC Joint Dislocation

Acute acromioclavicular (AC) joint dislocation is a frequent sports injury with more than 100 different operation methods described. A total of 65 patients with an acute AC joint dislocation were treated with the modified MINAR® system between 2009 and 2013. Clinical outcome, horizontal and vertical instability, as well as concomitant intraarticular injuries were assessed. We used Zanca, stress and axial X-rays for radiological assessment. A Constant score of 95 (±8.8), University of California Los Angeles Shoulder score (UCLA) of 31 (±4.9), Disabilities of Arm, Shoulder and Hand (DASH) of 9.1 (±14.3), and Visual Analogue Scale (VAS) of 0.9 (±0.126) was found. A total of 30 patients (59%) had no signs of reduction loss, nine patients (18%) a slight loss, 11 patients (22%) a partial loss, and one patient (2%) a total loss. No significant influence on the clinical scores could be shown. The postoperative coracoclavicular (CC) distance negatively affected the Constant (p = 0.007) and UCLA scores (p = 0.035). A longer time interval to surgery had a negative influence on all scores (p ≤ 0.001). We could not find any signs of persistent horizontal instability or intraarticular injuries at follow-up. The MINAR® system promises satisfactory functional and radiological results. When setting the correct indication, patients benefit from an early operation. No persisting horizontal instability was observed following suturing of the AC capsule and the delta fascia.
Characterization and Mapping of a Novel Premature Leaf Senescence Mutant in Common Tobacco (Nicotiana tabacum L.)

As the last stage of plant development, leaf senescence has a great impact on plant’s life cycle. Genetic manipulation of leaf senescence has been used as an efficient approach in improving the yield and quality of crop plants. Here we describe an ethyl methane sulfonate (EMS) mutagenesis induced premature leaf senescence mutant yellow leaf 1 (yl1) in common tobacco (Nicotiana tabacum L.). The yl1 plants displayed early leaf yellowing. Physiological parameters and marker genes expression indicated that the yl1 phenotype was caused by premature leaf senescence. Genetic analyses indicated that the yl1 phenotype was controlled by a single recessive gene that was subsequently mapped to a specific interval of tobacco linkage group 11 using simple sequence repeat (SSR) markers. Exogenous plant hormone treatments of leaves showed that the yl1 mutant was more sensitive to ethylene and jasmonic acid than the wild type. No similar tobacco premature leaf senescence mutants have been reported. This study laid a foundation for finding the gene controlling the mutation phenotype and revealing the molecular regulation mechanism of tobacco leaf senescence in the next stage.
Breast Cancer Stem Cells as Drivers of Tumor Chemoresistance, Dormancy and Relapse: New Challenges and Therapeutic Opportunities

Breast cancer is the most frequent cancer among women worldwide. Therapeutic strategies to prevent or treat metastatic disease are still inadequate although great progress has been made in treating early-stage breast cancer. Cancer stem-like cells (CSCs) that are endowed with high plasticity and self-renewal properties have been shown to play a key role in breast cancer development, progression, and metastasis. A subpopulation of CSCs that combines tumor-initiating capacity and a dormant/quiescent/slow cycling status is present throughout the clinical history of breast cancer patients. Dormant/quiescent/slow cycling CSCs are a key component of tumor heterogeneity and they are responsible for chemoresistance, tumor migration, and metastatic dormancy, defined as the ability of CSCs to survive in target organs and generate metastasis up to two decades after diagnosis. Understanding the strategies that are used by CSCs to resist conventional and targeted therapies, to interact with their niche, to escape immune surveillance, and finally to awaken from dormancy is of key importance to prevent and treat metastatic cancer. This review summarizes the current understanding of mechanisms involved in CSCs chemoresistance, dissemination, and metastasis in breast cancer, with a particular focus on dormant cells. Finally, we discuss how advancements in the detection, molecular understanding, and targeting of dormant CSCs will likely open new therapeutic avenues for breast cancer treatment.
A moment at the cell centre

I have been invited by the board of the French Society of Cell Biology (SBCF) to write a text around my presentation in the Symposium ‘A day at the Cell Centre’, held at the Curie Institute on May 17, 2019, and organized by four of my former students, namely Juliette Azimzadeh, Nathalie Delgehyr, Matthieu Piel and Manuel Théry. I have to thank them warmly for the quality of the science during this day. It was also a moving day for me indeed to listen to so many figures in the field.
A Short History of Evolution of Indigenous Plants and Medicine System

The importance of plants is well known to us. Life and its growth cannot be imagined without plants. Food for our survival is produced by plants and they also create a healthy and eco-friendly environment to live (Sazada et al., 2009). The use of various parts of different medicinal plants to cure specific ailments has been common from ancient times in India. The indigenous system of medicine namely Ayurvedic, Siddha and Unani have been in existence for many centuries. Apart from India, these systems are also prominent in Korea, China, Singapore, West Asia and many other countries. The knowledge of medicinal plants has been inherited traditionally therefore; the utilization of this knowledge has become important for human existence. In the old times, plants were used as remedies for the diseases. The oldest religious book of the World “Rigveda” provides information about the medicinal use of plant “Soma” as a medicinal agent by the Indo-Aryans, which was written between 4000 and 1600 B.C. (Bhattacharjee, 2004). The plant “Soma” is considered to have intoxicating characteristics. This plant is used for sacrificial objectives by Aryans and they also identified its juice as a stimulating beverage (Steiner, 1986). The Aryans also played a vital role in the presentation of therapeutical properties of other medicinal herbs and plants. The knowledge of Aryans about a large number of medicinal plants is demonstrated by the work of Charaka and Sushruta (Kirtikar, 1958). The ancient Indian literature is helpful in driving the current knowledge of using cinchona in malaria, digitalis, strophanthus and physostigma in heart diseases and of quassia as a bitter tonic. The indigenous system of medicine in the Indian sub-continent known as Ayurveda goes back to 700 B.C. and its systematization is attributed mostly to Charaka and Sushruta who have cited about 700 medicinal plants. The book “Sushruta Samhita” compiled in 1000 B.C. includes a comprehensive chapter on herbal therapeutics and contains remarkable information about the use of medicinal plants (Singh and Abrar, 1990).
Positive Outcomes of a Comprehensive Health Literacy Communication Training for Health Professionals in Three European Countries: A Multi-centre Pre-post Intervention Study

Many professionals have limited knowledge of how to address health literacy; they need a wider range of health literacy competencies to enhance empowerment and person-centred prevention. We evaluated whether: (1) a comprehensive health literacy training increased self-rated competencies of health professionals to address health literacy related problems and support the development of people’s autonomy and self-management abilities after training and 6–12 weeks later, (2) professionals were satisfied with the training, (3) outcomes differed for the three participating European countries. Health professionals (N = 106) participated in a multicentre pre-post intervention study in Italy, the Netherlands and Northern Ireland. The 8-hour training-intervention involved health literacy knowledge, the practice of comprehensible communication skills, shared decision-making, and enhancing self-management. Self-rated health literacy competencies and training satisfaction were assessed at baseline, immediately after training and 6-12 weeks later, and analysed by multi-level analysis. Professionals’ self-rated health literacy competencies significantly improved following training in all three countries; this increase persisted at 6-12 weeks follow-up. The strongest increase regarded professional’s skills to enhance shared-decision making and enabling self-management after training and follow-up respectively. Professionals perceived the training as relevant for practice. Competency increases seemed to be consistent across countries. In three countries, professionals’ self-rated health literacy competencies increased following this comprehensive training. These promising findings should be confirmed in a further full effect study. Implementation of this training in European education and health care may improve person-centred communication by professionals and might help to tackle health literacy related problems and to strengthen people’s abilities in achieving better health outcomes.
Combined reporting of surgical quality, cancer control and functional outcomes of Robot-assisted radical cystectomy with intracorporeal orthotopic neobladder into a novel Trifecta.

BACKGROUND To optimize outcomes reporting after Robot Assisted Radical Cystectomy (RARC) with intracorporeal orthotopic neobladder (iON), we proposed a novel Trifecta, aimed to overcome the available Pentafectas that neglect functional outcomes. METHODS A retrospective analysis of prospectively maintained RARC-iON dataset was performed. Baseline demographic, clinical, pathologic, perioperative and follow-up data were collected. Trifecta was defined as the coexistence of daytime urinary continence, Clavien-Dindo ≥ 3 complication-free and recurrence-free status, all assessed at 1 year. Kaplan-Meier method assessed the role of Trifecta achievement in predicting overall survival (OS) probabilities. Univariable and multivariable regression analyses identified predictors of Trifecta achievement. The predictive accuracy of Trifecta and other Pentafectas on 3-yr OS probability was plotted with receiver operating characteristic (ROC) analyses. RESULTS The Trifecta rate was 53% while 62% and 47% of patients achieved the University of Southern California (USC-P) and PROMETRICS group (PROM-P) Pentafectas, respectively. On tertile analysis, both Trifecta (p=0.011) and USC-P (p=0.043) rates significantly increased with surgical experience, while PROM-P did not (p=0.204). On ROC analysis, Trifecta was the only significant predictor of 3-yr OS probability (AUC=0.69, 95%CI:0.55-0.82; p=0.018). On Kaplan-Meier analysis, patients achieving Trifecta displayed significantly higher OS probability (p=0.032); adjusted for covariates, each incremental case was associated with a 2% increased probability (OR: 1.02) of achieving Trifecta on multivariable regression model. CONCLUSIONS Learning curve in RARC-iON has a significant impact on achievement of Trifecta. This tool combines accurate measurement of surgical proficiency with an independent predictive value in assessing 3-yr OS probabilities.
Keel Fracture Causes Stress and Inflammatory Responses and Inhibits the Expression of the Orexin System in Laying Hens

Simple Summary Keel fracture is an important health and welfare problem in laying hens in all production systems. Previous studies have shown that keel fracture can influence hens’ behavior, reduce production performances, and cause pain in laying hens. Additionally, keel fracture also affects their feed intake. However, it is not clear whether the keel fracture induces stress, inflammation, or influences the orexin systems in laying hens. Orexin, also called hypocretin, is associated with the regulation of feed intake, energy homeostasis, and metabolism in poultry animals. Therefore, this study aimed to investigate the effects of keel fracture on stress and inflammatory responses and the activity of the orexin system of laying hens. Our results indicate that keel fracture not only induced stress and inflammatory responses, but inhibited the activity of the orexin system in laying hens. This study provides insights into the adverse effects of keel fracture on laying hens. Abstract Keel fracture has negative effects on the health and welfare of laying hens. We investigated effects of keel fracture on stress, inflammation, and the orexin system in laying hens. Ninety 17-week-old Lohmann white laying hens were palpated and euthanatized at 42 weeks old, and marked as normal keel (NK)/fractured keel (FK) from absence/presence of keel fracture. Serum, brain, liver, and abdominal-muscle samples were collected from 10 NK and 10 FK hens to determine the stress and inflammatory responses and the activity of orexin systems by corticosterone content, expression of heat shock proteins (TNF-α 60, 70, 90), and inflammatory factors (tumor necrosis factor (TNF)-α, nuclear factor-kappa Bp65 (NF-κBp65), inducible nitric oxide synthase (iNOS), prostaglandin E synthases (PTGEs), cyclooxygenase-2 (COX-2), interleukin-1β (IL-1β)), orexin (ORX), and orexin-receptor 1/2 (ORXR1/ORXR2). The FK hens had higher serum corticosterone content, Hsps, and inflammatory factor mRNA expression levels than NK hens, although levels of iNOS in the liver and TNF-α in the muscle were similar. Protein levels of Hsp70 and Hsp90 in the brain and liver, iNOS and COX-2 in the liver, NF-κBp65, iNOS, and COX-2 in the brain of FK hens were increased compared with NK hens. Furthermore, FK hens had lower mRNA expression of ORX, ORXR1, and ORXR2 than NK hens. Therefore, keel fracture causes stress and inflammation, and inhibits the expression of the orexin system in laying hens.
MRI radiomic features are associated with survival in melanoma brain metastases treated with immune checkpoint inhibitors.

BACKGROUND Melanoma brain metastases historically portend a dismal prognosis, but recent advances in immune checkpoint inhibitors (ICIs) have been associated with durable responses in some patients. There are no validated imaging biomarkers associated with outcomes in patients with melanoma brain metastases receiving ICIs. We hypothesized that radiomic analysis of magnetic resonance images (MRIs) could identify higher-order features associated with survival. METHODS Between 2010 and 2019, we retrospectively reviewed patients with melanoma brain metastases who received ICI. After volumes of interest were drawn, several texture and edge descriptors, including first-order, Haralick, Gabor, Sobel, and Laplacian of Gaussian (LoG) features were extracted. Progression was determined using Response Assessment in Neuro-Oncology Brain Metastases. Univariate Cox regression was performed for each radiomic feature with adjustment for multiple comparisons followed by Lasso regression and multivariate analysis. RESULTS Eighty-eight patients with 196 total brain metastases were identified. Median age was 63.5 years (range, 19-91 y). Ninety percent of patients had Eastern Cooperative Oncology Group performance status of 0 or 1 and 35% had elevated lactate dehydrogenase. Sixty-three patients (72%) received ipilimumab, 11 patients (13%) received programmed cell death protein 1 blockade, and 14 patients (16%) received nivolumab plus ipilimumab. Multiple features were associated with increased overall survival (OS), and LoG edge features best explained the variation in outcome (hazard ratio: 0.68, P = 0.001). In multivariate analysis, a similar trend with LoG was seen, but no longer significant with OS. Findings were confirmed in an independent cohort. CONCLUSION Higher-order MRI radiomic features in patients with melanoma brain metastases receiving ICI were associated with a trend toward improved OS.
