It is difficult for radiologists to classify pneumoconiosis from category 0 to category 3 on chest radiographs. Therefore, we have developed a computer-aided diagnosis (CAD) system based on a three-stage artificial neural network (ANN) method for classification based on four texture features. The image database consists of 36 chest radiographs classified as category 0 to category 3. Regions of interest (ROIs) with a matrix size of 32 × 32 were selected from chest radiographs. We obtained a gray-level histogram, histogram of gray-level difference, gray-level run-length matrix (GLRLM) feature image, and gray-level co-occurrence matrix (GLCOM) feature image in each ROI...

The introduction of cell-free DNA (cfDNA) screening for aneuploidy into obstetric practice in 2011 revolutionized the strategies utilized for prenatal testing. The purpose of this document is to review the current data on the role of ultrasound in women who have undergone or are considering cfDNA screening. The following are SMFM recommendations: 1) in women who have already received a negative cfDNA screen, ultrasound at 11-14 weeks of gestation solely for the purpose of NT measurement (CPT code 76813) is not recommended (GRADE 1B); 2) we recommend that diagnostic testing should not be recommended to patients solely for the indication of an isolated soft marker in the setting of a negative cfDNA screen (GRADE 2B); 3) in women with an isolated soft marker without other clinical implications (ie, choroid plexus cyst or echogenic intracardiac focus) and a negative cfDNA screen, we recommend describing the finding as "not clinically significant" or as a "normal variant" (GRADE 2B); 4) in women with an isolated soft marker that has no other clinical implication (ie, choroid plexus cyst or echogenic intracardiac focus) and a negative first or second trimester screening result, we recommend describing the finding as "not clinically significant" or as a "normal variant" (GRADE 2B); 5) we recommend that all women in whom a structural abnormality is identified by ultrasound should be offered diagnostic testing with chromosomal microarray (GRADE 1A); 6) we recommend against routine screening for microdeletions with cfDNA (GRADE 1B)...

A validated simple, reliable and sensitive adsorptive anodic stripping voltammetric procedure is suggested for the accurate determination of antimony(III) on a glassy carbon electrode (GCE) in the presence of hematoxylin (HT), used as a chemical receptor in antimony analysis for the first time. Under optimized conditions, the plot of stripping peak current versus Sb(III) concentration showed two dynamic linear ranges, 1.0×10(-4) - 0.01µm (R(2) =0.9986) and 0.01 - 1.0µm (R(2) =0.9973) with a detection limit of 9...

Imaging techniques for mapping molecular distributions in tissue sections can reveal valuable information on biomolecules involved in relevant biochemical processes. A method has been developed for comprehensive, reproducible and sensitive lipid imaging by matrix-assisted laser/desorption ionization-LTQ-Orbitrap mass spectrometry in kidney sections, showing the benefits of exact mass determination. Matrix deposition parameters for positive and negative lipid ion imaging using different matrices such as 2,5-dihydroxybenzoic acid (DHB), 9-aminoacridine (9-AA) or α-cyano-4-hydroxycinnamic acid (CHCA) have been optimized for the broadest detection and identification of renal lipids...

Herein, iron and nitrogen co-doped carbon dots (Fe-N-CDs) were synthesized through a solvothermal method assisting with the microwave synthesis system for the first time. Multiple techniques were employed to characterize the properties of the obtained particles. The emphasis of current work was the confirmation of their intrinsic peroxidase activity due to the Fe doping, which is similar to natural ferriporphyrin. Through catalyzing the oxidization of 3,3',5,5'-Tetramethylbenzidine (TMB) in the presence of H2O2, the Fe-N-CDs exhibited a superior catalytic performance over horseradish peroxidase (HRP), suggesting their potential applications in catalytic area...

Psychological effects related to systemic lupus erythematosus (SLE) are tremendous. While a variety of psychological treatments have been applied to assist SLE patients, the effects of mindfulness practice were never documented in SLE. Mindfulness-based psychotherapy includes several techniques, including body-scan, breathing exercises, and full awareness during daily activities. In this case report, we present a first attempt at conducting mindfulness-based group therapy among SLE patients. Six female SLE patients participated in an 8-week program...

BACKGROUND: Malignant Melanoma (MM) is characterized by a growing incidence and a high malignant potential. Beside well defined prognostic factors such as tumor thickness and ulceration, the Mitotic Rate (MR) was included in the AJCC recommendations for diagnosis and treatment of MM. In daily routine, the identification of a single mitosis can be difficult on Hematoxylin&Eosin slides alone. Several studies showed a big inter- and intra-individual variability in detecting the MR in MM even by very experienced investigators, thus raising the question for a computer assisted method...

Women who report use of postpartum family planning may not continue their initial method or use it consistently. Understanding the patterns of method uptake, discontinuation, and switching among women after delivery is important to promote uptake and continuation of effective methods of contraception. This is a secondary analysis of 634 Malawian women enrolled into a prospective cohort study after delivery. They completed baseline surveys upon enrollment and follow-up telephone surveys 3, 6, and 12 months post-delivery...

Given the significant global burden of human trafficking, the ability of clinicians to identify and provide treatment for trafficked persons is critical. Particularly in conflict settings, health care facilities often serve as the first and sometimes only point of contact for trafficked persons. As such, medical practitioners have a unique opportunity and an ethical imperative to intervene, even in nonclinical roles. With proper training, medical practitioners can assist trafficked persons by documenting human trafficking cases, thereby placing pressure on key stakeholders to enforce legal protections, and by providing adequate services to those trafficked...

Evidence-based practice standards are not yet well defined for assisting potential victims of human trafficking. Nonetheless, health care professionals are learning to be first responders in identifying, treating, and referring potential victims. As more public and private sector resources are used to train health care professionals about human trafficking, more evaluation and research are needed to develop an effective standard of care. Adopting a public health lens and using the "National Standards for Culturally and Linguistically Appropriate Services in Health and Health Care" can guide critical decision making and actions...

This article is concerned with the link between the effects of pro-market pension reforms on women and familization/defamilization measures. It aims to contribute to the study of this link in three ways. Firstly, it identifies defamilization/familization measures that have the potential to reduce negative effects of pro-market pension measures on women. Secondly, based on the examples from the United Kingdom, it shows that the government's willingness to provide sufficient defamilization/familization measures to assist women to deal with the negative effects of the pro-market pension measures should not be taken for granted...

For event dynamic K-coverage algorithms, each management node selects its assistant node by using a greedy algorithm without considering the residual energy and situations in which a node is selected by several events. This approach affects network energy consumption and balance. Therefore, this study proposes a distributed and energy-efficient event K-coverage algorithm (DEEKA). After the network achieves 1-coverage, the nodes that detect the same event compete for the event management node with the number of candidate nodes and the average residual energy, as well as the distance to the event...

Vardit Ravitsky
The use of donor sperm or egg for reproduction raises the issue of the right of donor-conceived individuals to know their genetic origins. This paper argues in favor of acknowledging such a right and explores the challenges that cross-border medically assisted reproduction would raise in relation to it. It first explores possible justifications for such a right by discerning its possible conceptual and empirical groundings. It describes some key ethical and policy implications of the removal of donor anonymity...

Intraabdominal lymphangiomas are uncommon; additionally, those affecting the gastrointestinal tract are rare and account for less than 1% of cases. Intussusception caused by a cystic lymphangioma of the small bowel is extremely rare. The patient was a 20-year-old woman who visited our emergency room with a complaint of abdominal pain. A computed tomography image revealed ileo-ileal intussusception with a leading hypovascular mass measuring 1 cm in a diameter. Single-incision laparoscopic-assisted ileal resection was performed...

BACKGROUND: Pressure ulcers (PrUs) are a frequent, serious, and costly complication for veterans with spinal cord injury (SCI). The health care team should periodically identify PrU risk, although there is no tool in the literature that has been found to be reliable, valid, and sensitive enough to assess risk in this vulnerable population. OBJECTIVE: The immediate goal is to develop a risk assessment model that validly estimates the probability of developing a PrU...

BACKGROUND: Rectal prolapse is defined as the protrusion of the rectal wall through the anal canal; with a prevalence of less than 0.5%. The most frequent symptoms include pain, incomplete defecation sensation with blood and mucus, fecal incontinence and/or constipation. The surgical approach can be perineal or abdominal with the tendency for minimal invasion. Robot-assisted procedures are a novel option that offer technique advantages over open or laparoscopic approaches. CASE REPORT: 67 year-old female, who presented with rectal prolapse, posterior to an episode of constipation, that required manual reduction, associated with transanal hemorrhage during defecation and occasional fecal incontinence...

BACKGROUND: National Comprehensive Cancer Network (NCCN) guidelines recommend video-assisted thoracoscopic surgery (VATS) anatomical lobectomy as the first choice for the treatment of resectable lung cancer. However, sublobar resection offers significantly better functional preservation compared with lobectomy for stage I lung cancer. At present, the inferiority of sublobar resection to lobectomy is still uncertain. Herein, we compared the prognoses of these two types of surgical treatment for stage I lung adenocarcinoma...
