Spanish sperm specialists are about to shake up fertility research. In a study published in the scientific journal Cells this April, biologists working out of the University of the Basque Country/EHU report that they have developed a new method that will allow investigators to access sperm biomarkers from men with low sperm counts. Right now […]

Medial collateral ligament injuries are among the most common ligamentous knee injuries and frequently occur in both contact and noncontact settings.
The MCL complex consists of the superficial MCL, which is the primary restraint to valgus stress and plays a major role in controlling anteromedial rotatory instability (AMRI), and the deep MCL, which contributes to secondary valgus stability and control of AMRI.

Due to the robust healing potential of the MCL, most injuries have historically been treated nonoperatively (eg, knee bracing). However, recent evidence has

The FDA intends to hold an advisory committee meeting on SYD-101, which is being investigated for pediatric myopia but was not approved despite achieving endpoints in a phase 3 trial, according to a press release from Sydnexis.
The announcement follows a formal dispute resolution request that Sydnexis sent the FDA after the agency issued its complete response letter opting not to approve SYD-101 in October 2025.
SYD-101 is an investigational formulation of low-dose atropine 0.01%. Compounded atropine for pediatric progressive myopia management depends on access to compounding pharmacies and is

Structured lifestyle interventions significantly improved cognitive function in older adults across Latin America, according to a study presented at the Alzheimer’s Association International Conference 2026.
Lucia Crivelli, PhD, principal investigator at the neurological institute Fleni in Buenos Aires, and colleagues examined the effects of interventions into physical activity, healthy eating, cognitive training and social engagement on adults with elevated dementia risk and suboptimal cognition. Researchers found improvements in global cognition, memory, processing speed and executive

Cyclosporiasis, a parasitic illness that causes explosive diarrhea, is still surging throughout the country.
As of July 9, the CDC said it has received reports of 843 cyclosporiasis cases from 31 states since May 1, including 86 hospitalizations and no deaths, although the actual case count is likely larger given that the agency’s count includes only confirmed cases.
Michigan alone had reported 2,640 cases as of Monday. Other hard-hit states include New York and Ohio — both reporting cases in the hundreds.
Federal and state health officials have issued warnings about the illness, which can lead

Patients with cancer who have germline mutations overwhelmingly acknowledge the importance of informing relatives of their risks, but gaps in testing show the health care system has not adequately supported that mission.
A survey of nearly 2,000 patients with genetic variants predisposing them to cancer showed almost 90% viewed sharing results as their responsibility and notified their first-degree family members. However, nearly 30% of patients reported none of their relatives got tested, and many families only had partial uptake.
Survey data also showed medical oncologists and cancer surgeons

The cornea, lens, retina and biometry naturally take center stage when evaluating patients for cataract or refractive surgery.
What often goes overlooked is that subtle abnormalities of the eyelids can materially influence both surgical measurements and postoperative visual quality.
For some patients, addressing these issues before surgery can lead to better outcomes, improved patient satisfaction and a lower rate of postoperative surprises.
Ocular surface disease secondary to meibomian gland dysfunction and blepharitis is one of the most common and underrecognized culprits. Similarly, patients

NEW ORLEANS — In this video from the National Kidney Foundation Spring Clinical Meetings, Myda Khalid, MD, FASN, discusses the need for research in older and posttransplant patients with immunoglobulin A nephritis or IgA vasculitis nephritis.
Khalid, associate professor of clinical pediatrics at Riley Hospital for Children at Indiana University School of Medicine, discusses several pertinent questions concerning these subpopulations, including the safety and sequencing of certain medications as well as harmful drug interactions.
“We should be now exploring therapies in

NEW ORLEANS — In this video from the National Kidney Foundation Spring Clinical Meetings, Myda Khalid, MD, FASN, discusses current trials focused on treatments for children with immunoglobulin A vasculitis nephritis.
Khalid, associate professor of clinical pediatrics at Riley Hospital for Children at Indiana University School of Medicine, discusses several “really critical” ongoing trials looking at therapeutic agents for children with immunoglobulin A (IgA) vasculitis nephritis.
This includes the PIONEER trial, which is evaluating the safety and efficacy of atacicept-vymj

NEW ORLEANS — In this video from the National Kidney Foundation Spring Clinical Meetings, Myda Khalid, MD, FASN, discusses the pathophysiology of immunoglobulin A vasculitis nephritis, focusing on how this disease presents in children.
Khalid, associate professor of clinical pediatrics at Riley Hospital for Children at Indiana University School of Medicine, discusses symptoms of immunoglobulin A (IgA) vasculitis nephritis and how to measure kidney function in children vs. adults.
“We’ve used kidney function decline as a traditional marker of signs that the kidney is damaged,
