Research square

Trigiani L, Chernavsky N, Kim R, Hong N, Hawkins R +12 more

Plain English
This research studied how hypertension and the ApoE4 gene affect memory and brain function in male and female mice, particularly those experiencing changes similar to perimenopause. The researchers found that both male and female mice had memory problems and reduced brain blood flow, but the causes and responses to treatment varied between sexes. Specifically, a medication improved memory in both groups, but it worked through different mechanisms: restoring blood flow in males and reducing inflammation in females. Who this helps: This benefits patients at risk for Alzheimer's, especially women going through menopause.

Plain English
Researchers studied a way to deliver mRNA directly into neurons by using tiny vesicles produced by white blood cells, which can cross the protective barrier of the brain. They found that by engineering these vesicles to include components similar to retroviruses, they significantly improved the packaging of mRNA and its absorption by neurons, achieving better results in a mouse model with ongoing brain inflammation. This is important because effective mRNA delivery could lead to new treatments for neurological diseases. Who this helps: This helps patients with neurological conditions and their doctors looking for more effective therapies.

Drain Versus No Drain in Open Mesh Repair for Incisional Hernia, Results of a Prospective Randomized Controlled Trial.

2023

World journal of surgery

Willemin M, Schaffer C, Kefleyesus A, Dayer A, Demartines N +2 more

Plain English
This study looked at whether using a drain after surgery for incisional hernia would reduce complications compared to not using a drain. Researchers found that about 60% of patients in both groups had fluid collections after 30 days, but those who had drains experienced fewer surgical complications, like wound issues (21.7% with drains versus 42.7% without). This matters because it suggests that while drains don’t prevent fluid buildup, they can help reduce other surgical problems. Who this helps: This helps surgeons and patients by clarifying the role of drains in hernia repair surgery.

Injury

Guillier D, Sapino G, Schaffer C, Borens O, Thein E +2 more

Plain English
This study examined the outcomes of a specific surgical technique called propeller flap reconstruction for soft tissue injuries in the lower leg, particularly when metal support is present from previous surgeries. Researchers looked at 21 patients over a follow-up period of six months and found that those with metal structures underneath their skin flaps had longer hospital stays (average of 22 days) and higher failure rates (3 failures compared to 1) than those without metal (average stay of 12 days). This matters because it highlights the need for careful consideration when using propeller flaps in patients with internal metal, as it could lead to more complications and longer recovery times. Who this helps: This helps surgeons and medical teams involved in reconstructive surgery of the lower limb.

Plain English
This study examined a new method for repairing wounds in the groin area when standard surgical options are not safe or suitable. Researchers treated 15 patients who had complications from previous surgeries or other health issues, using skin and tissue from the abdomen to cover the wounds. The results showed that this approach worked well for everyone, with only two patients needing further treatment due to minor complications, and everyone recovering fully over an average follow-up period of about 2.4 years.

Lysosomal Function Impacts the Skeletal Muscle Extracellular Matrix.

2021

Journal of developmental biology

Coffey EC, Astumian M, Alrowaished SS, Schaffer C, Henry CA

Plain English
This study looked at how the functioning of lysosomes, which help break down proteins in muscle cells, affects muscle development and health. Researchers discovered that while muscle growth appeared normal at first in certain mutant cells, problems with the connective tissue at the junction where muscles attach to tendons led to muscle degeneration later on. Specifically, an increase in certain proteins like laminin 111 helped reduce muscle damage, while changes in another protein, MMP-9, did not significantly affect it. Who this helps: This research benefits patients with muscle-related diseases and their doctors by providing insights into muscle health and degeneration.

Plain English
This study looked at how changing the way doctors prescribe pain medication after tonsillectomy surgery can change the amount of opioids given to children. The researchers found that after introducing a standardized electronic order set, prescriptions for non-opioid pain relief increased, and there was a decrease in the amount of opioids prescribed, leading to more consistent prescribing practices. Importantly, patients did not experience any negative effects on pain management or safety outcomes. Who this helps: This benefits children undergoing tonsillectomy and their parents, as well as doctors prescribing pain medication.
