Background/purpose: We observed a high incidence of traumatic brain injuries (TBI) in properly restrained infants involved in higher speed motor vehicle crashes (MVCs). We hypothesized that car safety seats are inadequately protecting infants from TBI.
Methods: We retrospectively queried scene crash data from our State Department of Transportation (2007-2011) and State Department of Public Health data (2000-2011) regarding infants who presented to a trauma center after MVC.
Results: Department of Transportation data revealed 94% of infants in MVCs were properly restrained (782/833) with average speed of 44.6 miles/h when there was concern for injury. Department of Public Health data showed only 67/119 (56.3%) of infants who presented to a trauma center after MVC were properly restrained. Properly restrained infants were 12.7 times less likely to present to a trauma center after an MVC (OR=12.7, CI 95% 5.6-28.8, p<0.001). TBI was diagnosed in 73/119 (61.3%) infants; 42/73 (57.5%) properly restrained, and 31/73 (42.5%) improperly/unrestrained (p=0.34). Average head abbreviated injury scale was similar for properly restrained (3.2±0.2) and improperly/unrestrained infants (3.5±0.2, p=0.37).
Conclusion: Car safety seats prevent injuries. However, TBI is similar among properly restrained and improperly/unrestrained infants involved in higher speed MVCs who present to a trauma center.

The paper examines the impact of passive restraint on fire-induced spalling in concrete, utilizing a concrete mixture to minimize compositional variability. A variety of specimen geometries was prepared, including standard cubes and cylinders for the determination of mechanical properties and slabs of different dimensions for fire spalling tests conducted under controlled conditions. A top-opening Dragon furnace, which applies ISO 834-1 fire curves, was used to evaluate the influence of "cold rim" boundaries, where slab edges were insulated to create thermal restraint.

Activated CD4 T cells located at mucosal surfaces orchestrate local effector immune mechanisms. When properly polarized, these cells contribute to block infections at early stages and may be essential to restrain the local growth of mucosal tumors, playing a critical role in host protection. How CD4 T cells simultaneously integrate gut-homing instructions and Th polarization signals transmitted by TLR activated dendritic cells (DCs) is unknown.

Article Synopsis
- The study aimed to compare the effectiveness of Basic Life Support (BLS) skills on children and infants during transport in an ambulance, analyzing whether being secured to a stretcher made a difference.
- Data was collected from 24 Emergency Medicine Services providers performing BLS on child and infant manikins under various restraint conditions, revealing no major differences in BLS performance between secured and unsecured manikins for children.
- While compression depth for infants showed a statistical difference, it lacked clinical significance, and overall, both child and infant BLS performances fell short of American Heart Association guidelines.

Background: Poisoning is a significant health hazard and a leading cause of morbidity and mortality worldwide. India, being a predominantly agrarian country, routinely employs organophosphate (OP) pesticides in farming, and they are readily available "over the counter." OPs exert their toxicity by interfering with the normal function of acetylcholine, an essential neurotransmitter throughout the autonomic and central nervous systems.

FANCM is a DNA repair protein that recognizes stalled replication forks, and recruits downstream repair factors. FANCM activity is also essential for the survival of cancer cells that utilize the Alternative Lengthening of Telomeres (ALT) mechanism. FANCM efficiently recognizes stalled replication forks in the genome or at telomeres through its strong affinity for branched DNA structures.
