Coagulation abnormalities following brown recluse spider (Loxosceles reclusa) envenomation: A description of 2 cases and review of the literature.

Objective: Hemostatic abnormalities, including disseminated intravascular coagulation (DIC), are often cited as a common finding in patients following Loxosceles spider envenomation (ie, loxoscelism). The prevalence and severity of coagulopathy, however, particularly following L reclusa (ie, brown recluse) envenomation, is not well described. This study aimed to characterize coagulation laboratory parameters and coagulopathy in patients following L reclusa envenomation.

Novel index for the evaluation of wound healing following erupted tooth extraction.

Background: Understanding healing of the alveolar process is crucial for immediate implant, alveolar ridge preservation and guided bone regeneration procedures, and to evaluate it several different scales have been proposed; however, all have different characteristics and seem to miss a standardization allowing for an objective and dichotomous evaluation of the different aspects of wound healing. The objective of the present study is to propose and apply, in real clinical scenarios, a novel index for the objective evaluation of wound healing following erupted tooth extraction.

Methods: Healthy patients in need of a single tooth extraction were enrolled and re-examined at 7, 14 and 21 days after the extraction using the novel index proposed.

Validation of a Pretransplant Risk Prediction Model for Early Allograft Dysfunction After Living-donor Liver Transplantation.

Background: Early allograft dysfunction (EAD) affects outcomes in liver transplantation (LT). Existing risk models developed for deceased-donor LT depend on posttransplant factors and fall short in living-donor LT (LDLT), where pretransplant evaluations are crucial for preventing EAD and justifying the donor's risks.

Methods: This retrospective study analyzed data from 2944 adult patients who underwent LDLT at 17 centers between 2016 and 2020.

A pilot, randomized controlled trial of Dual Daily HIV and sexually transmitted infection pre-exposure prophylaxis using tenofovir disoproxil fumarate/emtricitabine and doxycycline in gay, bisexual and other men who have sex with men and transgender women: The DuDHS Study.

Background: Men who have sex with men (MSM) and transgender women experience high sexually transmitted infection (STI) rates. This study evaluated the feasibility of doxycycline pre-exposure prophylaxis (doxyPrEP) for STI prevention in these key populations.

Methods: Sexually-active MSM and transgender women without HIV with prior syphilis were recruited.

Evaluating allograft risk models in organ transplantation: Understanding and balancing model discrimination and calibration.

In the field of organ transplantation, the accurate assessment of donor organ quality is necessary to efficient organ allocation and to informed consent for recipients. A common approach to organ quality assessment is the development of statistical models that accurately predict post-transplant survival by integrating multiple characteristics of the donor and allograft. Despite the proliferation of predictive models across many domains of medicine, many physicians may have limited familiarity with how these models are built, the assessment of how well models function in their population and the risks of a poorly performing model.

Ejtm3 experiences after ChatGPT and other AI approaches: values, risks, countermeasures.

To study its pathogenesis, we developed a human challenge model in which we infect the skin on the upper arm of human volunteers with to the pustular stage of disease. The model has been used to define lesional architecture, describe the immune infiltrate into the infected sites using flow cytometry, and explore the molecular basis of the immune response using bulk RNA-seq.

Antiplatelet Agents in Endovascular Neurointerventional Procedures.

Minimally invasive, image-guided endovascular procedures are becoming increasingly prevalent as techniques and technologies have advanced, particularly within the realm of neurovascular interventions. Endovascular approaches ubiquitously result in endothelial injury with subsequent risk of thromboembolic complications. Periprocedural antiplatelet agent use is an integral component of the management of patients undergoing endovascular neurointerventional procedures.

Dysregulation of lung epithelial cell homeostasis and immunity contributes to Middle East respiratory syndrome coronavirus disease severity.

Coronaviruses (CoV) emerge suddenly from animal reservoirs to cause novel diseases in new hosts. Discovered in 2012, the Middle East respiratory syndrome coronavirus (MERS-CoV) is endemic in camels in the Middle East and is continually causing local outbreaks and epidemics. While all three newly emerging human CoVs from the past 20 years (SARS-CoV, SARS-CoV-2, and MERS-CoV) cause respiratory disease, each CoV has unique host interactions that drive differential pathogeneses.

Parental knowledge, awareness, and attitudes towards children's oral habits: a descriptive cross-sectional study.

Background: Oral health is fundamental to children's health and well-being. Parental knowledge, awareness, and practices towards oral habits significantly influence children's oral health. Early diagnosis and intervention to break abnormal oral habits are vital to prevent long-term detrimental effects on oral and facial development.

A Framework for Assessing Viral Pathogens: A Key Element of the BARDA Emerging Infectious Diseases Strategy.

The COVID-19 pandemic has revealed the need for nations to prepare more effectively for emerging infectious diseases. Preparing for these threats requires a multifaceted approach that includes assessing pathogen threat, building flexible capabilities for rapid medical countermeasure (MCM) development, and exercising, maintaining, and improving those response capabilities. The Biomedical Advanced Research and Development Authority (BARDA) promotes the advanced development of MCMs in response to natural and manmade threats.

The Association Between Blepharitis and Lower Eyelid Ectropion in a Large Cohort of Patients.

Purpose: Blepharitis and lower eyelid ectropion are highly prevalent ocular conditions occurring in 37%-46% and 2-3% of the general adult population, respectively. Blepharitis has multifactorial origins and involves anterior and posterior types of eyelid inflammation. Lower eyelid ectropion results in ocular surface exposure, epiphora and chronic conjunctivitis.

Fecal Calprotectin Correlates with Disease Extent but Remains a Reliable Marker of Mucosal Healing in Ulcerative Colitis.

Background And Aims: Fecal calprotectin (FC) is a marker of mucosal inflammatory activity in ulcerative colitis (UC). FC levels may also be influenced by the extent of disease. We aimed to examine the relationships between FC, mucosal activity, and disease extent, and to assess how disease extent affects the diagnostic accuracy of FC.

Associations of Traumatic Brain Injury and Mild Behavioral Impairment With Cognitive Function and Dementia.

Objective: Traumatic Brain Injury (TBI) may contribute additional complexity to the clinical picture of mild behavioral impairment (MBI). MBI, a behavioral analog to mild cognitive impairment (MCI), is comprised of five neuropsychiatric domains: decreased motivation, affective dysregulation, impulse dyscontrol, social inappropriateness, and abnormal perception/thought content. We investigated (1) if cross-sectional associations of cognitive status with MBI symptoms differ by TBI status and (2) if prospective associations of MBI domain positivity with incident dementia risk differ by TBI status.

Characterizing Antisense Oligonucleotide-Induced Histopathology Findings in Spinal Cord of Mauritius Cynomolgus Monkeys by Molecular Localization Investigation.

The safety of a 2'--methoxyethyl antisense oligonucleotide (ASO) was investigated in Mauritius cynomolgus monkeys in a 41-week Good Laboratory Practice (GLP) toxicity study after multiple intrathecal (IT) administrations. Histopathological examination revealed ectopic formation of lymphoid follicles in the spinal cord (SC) at the injection site at all doses and the presence of granular material in neurons of the SC in high-dose animals. The granular material was seen in all the segments of the SC, but mainly in the lumbar segment and persisted at the end of the 26-week recovery period, while the lymphoid follicles showed a reversibility trend.

Emerging therapeutic strategies in Lynch syndrome-associated colorectal cancer and the role of MMR testing.

Lynch syndrome is the most common hereditary cancer predisposition, accounting for 1-5% of colorectal cancer cases, and is driven by germline mutations in DNA mismatch repair genes. Despite established diagnostic criteria, such as the Amsterdam guidelines, Lynch syndrome remains largely underdiagnosed. To address this gap, universal tumour screening has been introduced for all newly diagnosed cases of colorectal cancer and endometrial cancer, significantly improving early detection.

Long-Term Intracranial Progression-Free Survival in Lung Cancer Brain Metastases Extended Beyond 50 Months with Gubenxiaoyi Formula (GBXY): A Groundbreaking Case Study.

Background: The prevalence of brain metastases (BM) in lung cancer patients is notably high and is associated with poor prognoses. The efficacy of standard treatment regimens in improving intracranial progression-free survival (IPFS) for lung cancer BM is markedly limited. While traditional Chinese medicine (TCM) has been effective in enhancing the quality of life and prognosis of lung cancer patients, its efficacy in treating BM remains unreported.
