Background: Crimean-Congo hemorrhagic fever (CCHF) is acute viral infection and a major emerging infectious diseases threat, affecting a large geographical area. There is no proven antiviral therapy and it has a case fatality rate of 4-30%. The natural history of disease and outcomes of CCHF in pregnant women is poorly understood.
Objectives: To systematically review the characteristics of CCHF in pregnancy, and report a case series of 8 CCHF cases in pregnant women from Russia, Kazakhstan and Turkey.
Methods: A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement protocol. PubMed, SCOPUS, Science Citation Index (SCI) were searched for reports published between January 1960 and June 2016. Two independent reviewers selected and reviewed studies and extracted data.
Results: Thirty-four cases of CCHF in pregnancy were identified, and combined with the case series data, 42 cases were analyzed. The majority of cases originated in Turkey (14), Iran (10) and Russia (6). There was a maternal mortality of 14/41(34%) and fetal/neonatal mortality of in 24/41 cases (58.5%). Hemorrhage was associated with maternal (p=0.009) and fetal/neonatal death (p<0.0001). There was nosocomial transmission to 38 cases from 6/37 index pregnant cases.
Conclusion: Cases of CCHF in pregnancy are rare, but associated with high rates of maternal and fetal mortality, and nosocomial transmission.

Division of Gastrointestinal and Minimally Invasive Surgery, Department of Surgery, Carolinas Medical Center, 1025 Morehead Medical Drive Suite 300, Charlotte, NC, 28204, USA.
Purpose: To present updated outcomes after previously describing a novel technique for the robotic repair of parastomal hernias.
Methods: Patients who underwent parastomal hernia repair with a robotic Sugarbaker technique at a tertiary hernia center were identified from an institutional database. The approach involves mesh placement in the intraperitoneal or preperitoneal position after closure of the fascial defect.

Alzheimers Dement
December 2024
Krembil Research Institute, Toronto, ON, Canada.
Background: An explicit molecular level understanding of Alzheimer's Disease (AD) remains elusive. What initiates the disease and why does it progress? Answering these questions will be crucial to the development of much needed new diagnostics and therapeutics. Though the amyloid hypothesis is often debated, recent biologic trial results support a role for Aβ in AD pathogenesis.

December 2024
University of Washington, Seattle, WA, USA.
Background: The BRAIN Initiative has stimulated development of novel single cell and spatial molecular approaches to understand human brain structure and function. However, traditional methods for human brain specimen collection, including retrospective archival tissues, have not been optimized for these latest methods. A modernized approach that optimizes tissue quality, anatomical precision, and comprehensive, quantitative neuropathological assessments is needed to maximize the impact of the tremendous investment and remarkable technological advances in human neuroscience research.

In recent years, there has been a concerted effort to objectively quantify these changes using the latest advances in Natural Language Processing (NLP) tools. Much academic research has been conducted to evaluate how these speech characteristics change with the course of illness, but they have yet to be elevated beyond exploratory endpoints in trials.
