What does G Merra research?

G Merra studies how the bacteria in our gut (gut microbiota) can affect various health conditions, including those affecting bones, muscles, and even the immune system. They are particularly interested in conditions like COVID-19, myotonic dystrophy type 2, type 1 diabetes, and pancreatic cancer, exploring how diet and gut health influence these diseases. G Merra's research also looks at the use of medical tests and treatments, aiming to improve patient care based on the relationship between gut bacteria and health outcomes.

Key findings

  • In COVID-19 patients, high amylase levels were linked to more severe cases needing ICU care but not increased death rates, revealing that these levels signal a need for intensive care.
  • One-third of men and 22% of women with myotonic dystrophy type 2 were severely obese, highlighting body composition's link to muscle strength and movement quality.
  • The ANCOC score predicted the risk of death for COVID-19 patients with 92% accuracy, helping doctors make better decisions in emergencies.
  • Patients treated for non-variceal upper gastrointestinal bleeding in Short Stay Units had shorter hospital stays and less need for blood transfusions without an increase in complications.
  • Changes in gut microbiota were found to impact the development of autoimmune diseases like Type 1 diabetes, suggesting that modifying gut bacteria could help manage these conditions.

Hyperamylasemia in COVID-19 patients: pancreatic involvement or secondary epiphenomenon?

2025

Internal and emergency medicine

Candelli M, Calce R, Pignataro G, Racco S, Fuorlo M +6 more

Plain English
This study looked at whether high levels of amylase in the blood of COVID-19 patients are due to issues with the pancreas or if they are simply related to the severity of the COVID-19 illness itself. Researchers reviewed data from 1,858 COVID-19 patients and found that high amylase levels were linked to more severe cases needing ICU care, but not to increased death rates or actual pancreatic inflammation, which was only seen in four patients. This is important because it shows that high amylase levels in COVID-19 patients signal the need for more intensive care, rather than indicating a pancreatic problem. Who this helps: This helps doctors treating COVID-19 patients by guiding them on how to respond to high amylase levels.

Ursodeoxycholic acid does not affect the clinical outcome of SARS-CoV-2 infection: A retrospective study of propensity score-matched cohorts.

2024

Liver international : official journal of the International Association for the Study of the Liver

Marrone G, Covino M, Merra G, Piccioni A, Amodeo A +5 more

Plain English
This study looked at whether ursodeoxycholic acid (UDCA) affects the outcomes for patients hospitalized with COVID-19. Researchers compared 109 patients taking UDCA to 520 others not on the drug and found that 24.1% of those on UDCA died compared to 22.6% of those who were not, showing no significant difference in survival rates. This matters because it suggests that UDCA does not improve the chances of surviving COVID-19, indicating that other factors like age and pneumonia are much more important in determining outcomes. Who this helps: This helps doctors understand that UDCA is unlikely to benefit COVID-19 patients.

Reduced Prognostic Role of Serum PCT Measurement in Very Frail Older Adults Admitted to the Emergency Department.

2023

Antibiotics (Basel, Switzerland)

Russo A, Salini S, Gava G, Merra G, Piccioni A +8 more

Plain English
This study focused on older adults aged 80 and above who were admitted to the emergency department with suspected infections. It found that for those who were fit or moderately frail, higher levels of a substance called PCT in their blood were linked to a higher chance of dying in the hospital and being diagnosed with an infection. However, for very frail patients, PCT levels didn't predict death or infection risk, although they still helped identify bloodstream infections. Who this helps: This helps doctors understand how to better assess infection risks in older patients based on their frailty level.

Are Short-Stay Units Safe and Effective in the Treatment of Non-Variceal Upper Gastrointestinal Bleeding?

2023

Medicina (Kaunas, Lithuania)

Candelli M, Lumare M, Riccioni ME, Mestice A, Ojetti V +6 more

Plain English
This study looked at whether a Short Stay Unit (SSU) can safely and effectively treat patients with non-variceal upper gastrointestinal bleeding (NVUGIB) compared to regular hospital wards. It found that patients treated in the SSU had a shorter hospital stay, less need for blood transfusions, and quicker access to endoscopy, all without a rise in return visits to the hospital or deaths. This matters because it suggests that using SSUs could help alleviate overcrowding in emergency departments while still providing quality care. Who this helps: This helps patients with gastrointestinal bleeding by providing quicker and more efficient treatment.

Plain English
This study looked at how frailty, measured by the Clinical Frailty Scale (CFS), affects the health outcomes of patients aged 80 and older who come to the emergency room with small bowel obstruction (SBO). Researchers found that patients with a CFS score of 7 or higher faced a higher risk of in-hospital death (20.8% compared to 8.6%), had longer hospital stays (averaging 9 days versus 7), and were more likely to experience major complications (29.9% versus 17.9%). Understanding frailty in these patients is important because it helps doctors determine how closely to monitor them and what treatment goals to set. Who this helps: This research benefits older patients with SBO and their doctors, improving care tailored to their health risks.

2023

Journal of clinical medicine

Candelli M, Sacco Fernandez M, Pignataro G, Merra G, Tullo G +5 more

Plain English
This study looked at a scoring system called the ANCOC score, which helps doctors predict the risk of death for COVID-19 patients based on five key factors: age, kidney function, inflammation levels, oxygen levels, and any other health issues. Researchers found that a score of -1 or lower meant no mortality risk, while a score of 6 indicated a 100% risk of death, with a high accuracy of 92%. The study confirmed that this score can effectively predict a patient's risk of dying within 60 days, regardless of their vaccination status or which variant of the virus they have. Who this helps: This helps doctors making decisions in emergency rooms.

Plain English
This study looked at whether testing for procalcitonin (PCT) levels and taking blood cultures (BC) in the emergency department helped predict outcomes for patients with urinary tract infections (UTIs). Researchers studied 1,029 patients and found that testing did not significantly affect how long patients stayed in the hospital or their chances of survival, with a mortality rate of only 6.6%. This is important because it suggests that these tests may not be necessary for most patients with UTIs, allowing doctors to focus more on effective treatment rather than unnecessary testing. Who this helps: This helps doctors treating patients with urinary tract infections.

Plain English
This study looked at how well the drug dronedarone works and its safety for patients who developed hyperthyroidism from taking amiodarone, specifically focusing on those with a heart condition called atrial fibrillation. Out of 124 participants, 56 switched to dronedarone; after 12 months, 56% of these patients showed improvement in their thyroid levels, compared to only 8.9% of those who continued taking amiodarone. This finding is important because it suggests that dronedarone may be a safer option for treating atrial fibrillation in patients with hyperthyroidism caused by amiodarone.

Plain English
This study looked at very-low-calorie ketogenic diets (VLCKDs) that provide less than 800 calories per day to see how they affect weight loss and health over three weeks. Participants on the first diet (VLCKD1) lost about 11% of their body weight and saw improvements in fat mass and insulin sensitivity, but also experienced increases in certain blood markers. The second diet (VLCKD2) led to similar weight loss but had slightly different effects on blood chemistry, though overall, neither diet harmed nutritional health or caused negative side effects. Who this helps: This research benefits patients looking for effective weight loss solutions under medical guidance.
