Genomic instability in individuals with sex determination defects and germ cell cancer.

The ability to transmit genetic information through generations depends on the preservation of genome integrity. Genetic abnormalities affect cell differentiation, causing tissue specification defects and cancer. We addressed genomic instability in individuals with Differences of Sex Development (DSD), characterized by gonadal dysgenesis, infertility, high susceptibility for different types of cancer, especially Germ Cell Tumors (GCT), and in men with testicular GCTs.

Transepithelial Barrier Dysfunction Drives Microbiota Dysbiosis to Initiate Epithelial Clock-driven Inflammation.

Background: Factors that contribute to inflammatory bowel disease [IBD] pathogenesis include genetic polymorphisms, barrier loss, and microbial dysbiosis. A major knowledge gap exists in the origins of the colitogenic microbiome and its relationship with barrier impairment. Epithelial myosin light chain kinase [MLCK] is a critical regulator of the paracellular barrier, but the effects of MLCK activation on the intraepithelial bacteria [IEB] and dysbiosis are incompletely understood.

Pathogenic role of Twist-1 protein in hydatidiform molar pregnancies and investigation of its potential diagnostic utility in complete moles.

Background: Complete and partial moles (PM) are the most common gestational trophoblastic diseases. Due to some overlapping morphological findings, ancillary studies may be necessary.

Methods: In this cross-sectional study, 47 cases of complete mole (CM) and 40 cases of PM were randomly selected based on histopathological criteria.

Sex-Related Differences in Patient Characteristics, Risk Factors, and Symptomatology in Older Adults with Pulmonary Embolism: Findings from the SERIOUS-PE Study.

Sex-specific factors are implicated in pulmonary embolism (PE) presentation in young patients, as indicated by increased risk in pregnancy. Whether sex differences exist in PE presentation, comorbidities, and symptomatology in older adults, the age group in which most PEs occur, remains unknown. We identified older adults (aged ≥65 years) with PE in a large international PE registry replete with information about relevant clinical characteristics (RIETE registry, 2001-2021).

Clinicopathologic Predictors of Clinical Outcomes in Mammary Adenoid Cystic Carcinoma: A Multi-institutional Study.

Adenoid cystic carcinoma (AdCC) is an uncommon type of invasive breast carcinoma with a favorable prognosis. However, some cases are aggressive. The study aims to define the clinicopathologic predictors of outcome.

LHRH conjugated gold nanoparticles assisted efficient ovarian cancer targeting evaluated spectral photon-counting CT imaging: a proof-of-concept research.

Emerging multifunctional nanoparticulate formulations take advantage of nano-meter scale size and surface chemistry to work as a therapeutic delivery agent and a diagnostic tool for non-invasive real-time monitoring using imaging technologies. Here, we evaluate the selective uptake of 18 nm and 80 nm sized gold nanoparticles (AuNPs) by SKOV3 (4 times higher) ovarian cancer (OC) cells (compared to OVCAR5) , quantified by inductively coupled plasma (ICP) and MARS spectral photon-counting CT imaging (MARS SPCCT). Based on analysis, pristine AuNPs (18 nm) and surface modified AuNPs (18 nm) were chosen as a contrast agent for MARS SPCCT.

Low-dose interleukin-2 treatment increases the proportion of regulatory T cells in patients with rheumatic diseases: A meta-analysis.

Background: It is now accepted that immune tolerance disorders caused by inadequate Treg cell function or number are important factors in the development and progression of rheumatic diseases. There is increasing evidence that ld IL-2 treatment increases the proportion of Treg cells in patients' peripheral blood, but this conclusion is still controversial. Here, we performed a meta-analysis of reports documenting the proportion of Treg cells and the rate of adverse events in patients with rheumatic disease before and after the administration of ld IL-2 to better understand its effect and safety on Treg cells in the field of rheumatic diseases.

Length-of-Stay in the Emergency Department and In-Hospital Mortality: A Systematic Review and Meta-Analysis.

The effect of emergency department (ED) length of stay (EDLOS) on in-hospital mortality (IHM) remains unclear. The aim of this systematic review and meta-analysis was to determine the association between EDLOS and IHM. We searched the PubMed, Medline, Embase, Web of Science, Cochrane Controlled Register of Trials, CINAHL, PsycInfo, and Scopus databases from their inception until 14−15 January 2022.

Consequences of trisomy syndromes - 21 and beyond.

The mechanisms underlying pathologies in Down syndrome remain poorly understood. In this forum article we compare the cellular phenotypes of chromosome 21 trisomy with other trisomic cells. We argue that both effects of the extra chromosome 21 and the global consequences of chromosome gain must be considered to understand complex pathologies of Down syndrome.

Consequences of chromosome gain: A new view on trisomy syndromes.

Chromosome gains are detrimental for the development of the human embryo. As such, autosomal trisomies almost always result in spontaneous abortion, and the rare embryos surviving until live birth suffer from a plethora of pathological defects. There is no treatment currently available to ameliorate the consequences of trisomies, such as Down syndrome (trisomy of chromosome 21).

Dual Immunostimulatory Pathway Agonism through a Synthetic Nanocarrier Triggers Robust Anti-Tumor Immunity in Murine Glioblastoma.

Myeloid cells are abundant, create a highly immunosuppressive environment in glioblastoma (GBM), and thus contribute to poor immunotherapy responses. Based on the hypothesis that small molecules can be used to stimulate myeloid cells to elicit anti-tumor effector functions, a synthetic nanoparticle approach is developed to deliver dual NF-kB pathway-inducing agents into these cells via systemic administration. Synthetic, cyclodextrin-adjuvant nanoconstructs (CANDI) with high affinity for tumor-associated myeloid cells are dually loaded with a TLR7 and 8 (Toll-like receptor, 7 and 8) agonist (R848) and a cIAP (cellular inhibitor of apoptosis protein) inhibitor (LCL-161) to dually activate these myeloid cells.

A simplified approach to ovarian lesions based on the O-RADS US risk stratification and management system.

Compared to the risk-oriented approach to ovarian lesions that is presented in the Ovarian- Adnexal Reporting and Data System (O-RADS) US Risk Stratification and Management System as a guideline, a lesion-oriented flowchart is more user-friendly for radiologists. In the present article, the O-RADS guideline has been depicted in the form of a single flowchart to explain how to approach ovarian lesions in an algorithmic manner. In addition to providing a practical flowchart, this pictorial article contains some images of the related ovarian lesions.

Local epidermal growth factor delivery using nanopillared chitosan-gelatin films for melanogenesis and wound healing.

Epidermal growth factor (EGF) is required for various regulations of skin tissue including wound healing; however, it has limited stability due to the physicochemical conditions of the wound milieu. The lack of functional EGF within the wound can cause permanent tissue defects and therefore, current wound patch designs involve EGF-releasing components. Consequently, the focus of such systems is to improve the wound healing mechanism, with minimal attention on melanogenesis of the scar tissue.

The Role of Health Information Technology in Improving Awareness of Human Papillomavirus and Human Papillomavirus Vaccine Among U.S. Adults.

Although human papillomavirus (HPV) vaccines prevent cancer-causing HPV infections and cervical precancers, there is suboptimal awareness and limited global accessibility of HPV and HPV vaccine. Emerging evidence suggests that health information technology (HIT) may influence HPV-related awareness and improve vaccine adoption. The objective of this study was to evaluate the link between HIT and HPV-related awareness Data were obtained from 1,866 U.

The Diagnostic Value of Ultrasound-Guided Cervical Core Needle Biopsy in Diagnosis of Lymphoma in Suspected Patients.

Core needle biopsy (CNB) guided by imaging modalities seems to be an acceptable modality for diagnosis of lymphoma due to its safety, good applicability, availability as well as diagnostic accuracy, however; Studies have not reached a consensus on its diagnostic accuracy and factors affecting its performance. The present study aimed to assess the value of ultrasound-guided cervical CNB in the diagnosis of lymphoma in suspected patients. This cross-sectional study was performed on 46 consecutive patients (20 to 82 years) with cervical mass or lymphadenopathy suspected of lymphoma and were candidates for diagnostic evaluation.

Assessing The Role and Accuracy of Ultrasonographic Imaging in The Diagnosis of Deep Infiltrating Endometriosis: A Cross-Sectional Study.

Background: Deep infiltrating endometriosis (DIE) is described as an endometriotic tissue that penetrates more than 5 mm under the peritoneal surface. It's suggested that trans vaginal sonography (TVS) is 79% sensitive and 94% specific in the assessment of intestinal DIE. Considering the possibility that DIE ultrasonography (rectal and\or vaginal ultrasonography) might be more accurate, we designed this study to assess this study to evaluate the accuracy of DIE ultrasonography.

Deep learning super-resolution magnetic resonance spectroscopic imaging of brain metabolism and mutant isocitrate dehydrogenase glioma.

Background: Magnetic resonance spectroscopic imaging (MRSI) can be used in glioma patients to map the metabolic alterations associated with mutations that are central criteria for glioma diagnosis. The aim of this study was to achieve super-resolution (SR) MRSI using deep learning to image tumor metabolism in patients with mutant IDH glioma.

Methods: We developed a deep learning method based on generative adversarial network (GAN) using Unet as generator network to upsample MRSI by a factor of 4.

Neonatal cardiac tamponade, a life-threatening complication secondary to peripherally inserted central catheter: a case report.

Background: Although the use of a peripherally inserted central catheter (PICC) has many advantages for the treatment of neonates, catheter malposition may result in serious complications that could be life-threatening. We report the case of a 10-day-old neonate with cardiac tamponade secondary to a PICC line who was successfully treated by pericardiocentesis.

Case Presentation: An Iranian (Asian) preterm male neonate was born by Cesarean section with a birth weight of 1190 g and a first-minute Apgar score of 7.

PACAP-PAC1R modulates fear extinction via the ventromedial hypothalamus.

Exposure to traumatic stress can lead to fear dysregulation, which has been associated with posttraumatic stress disorder (PTSD). Previous work showed that a polymorphism in the PACAP-PAC1R (pituitary adenylate cyclase-activating polypeptide) system is associated with PTSD risk in women, and PACAP (ADCYAP1)-PAC1R (ADCYAP1R1) are highly expressed in the hypothalamus. Here, we show that female mice subjected to acute stress immobilization (IMO) have fear extinction impairments related to Adcyap1 and Adcyap1r1 mRNA upregulation in the hypothalamus, PACAP-c-Fos downregulation in the Medial Amygdala (MeA), and PACAP-FosB/ΔFosB upregulation in the Ventromedial Hypothalamus dorsomedial part (VMHdm).
