Article Synopsis
  • Natural killer (NK) cells play a key role in fighting malaria through a mechanism called antibody-dependent cellular cytotoxicity (ADCC), but how different factors influence NK cell activation is not fully understood.
  • A study compared NK cells from people exposed to malaria in Uganda with those who had never been exposed, finding that malaria-exposed individuals had stronger ADCC but weaker inflammatory responses, as evidenced by changes in NK cell surface markers.
  • The effectiveness of NK cell degranulation varied based on the type of erythrocytes and plasma used, with the best responses seen using certain sickle cell erythrocytes and plasma from high-transmission areas, while responses to clinical parasite strains were less effective compared to standard laboratory strains.

Background: Acute declines in estimated glomerular filtration rate (eGFR) occur commonly after starting angiotensin-converting enzyme inhibitors. Whether declines in eGFR that occur after simultaneously starting angiotensin-converting enzyme inhibitors with other antihypertensive agents modifies the benefits of these agents on cardiovascular outcomes is unclear.

Methods And Results: We identified predictors of acute declines in eGFR (>15% over 3 months) during randomization to benazepril plus amlodipine versus benazepril plus hydrochlorothiazide in the ACCOMPLISH (Avoiding Cardiovascular Events through Combination Therapy in Patients Living with Systolic Hypertension) trial.

Objective: Recent clinical guidelines for sepsis management emphasize immediate antibiotic initiation for suspected septic shock. Though hypotension is a high-risk marker of sepsis severity, prior studies have not considered the precise timing of hypotension in relation to antibiotic initiation and how clinical characteristics and outcomes may differ. Our objective was to evaluate antibiotic initiation in relation to hypotension to characterize differences in sepsis presentation and outcomes in patients with suspected septic shock.

Persistent activation of hepatic stellate cells (HSCs) in the injured liver leads to the progression of liver injury from fibrosis to detrimental cirrhosis. In a previous study, we have shown that survivin protein is upregulated during the early activation of HSCs, which triggers the onset of liver fibrosis. However, the therapeutic potential of targeting survivin in a fully established fibrotic liver needs to be investigated.

Background: Prior research suggests clinical effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors (SGLT2is) are mediated by changes in glycated hemoglobin, body weight, systolic blood pressure, hematocrit, and urine albumin-creatinine ratio. We aimed to confirm these findings using a meta-analytic approach.

Methods And Results: We updated a systematic review of 9 GLP-1RA and 13 SGLT2i trials and summarized longitudinal mediator data.

Introduction: This study aimed to understand whether older adults' longitudinal completion of assessments in an online Alzheimer's disease and related dementias (ADRD)-related registry is influenced by self-reported medical conditions.

Methods: Brain Health Registry (BHR) is an online cognitive aging and ADRD-related research registry that includes longitudinal health and cognitive assessments. Using logistic regressions, we examined associations between longitudinal registry completion outcomes and self-reported (1) number of medical conditions and (2) eight defined medical condition groups (cardiovascular, metabolic, immune system, ADRD, current psychiatric, substance use/abuse, acquired, other specified conditions) in adults aged 55+ ( 23,888).

Article Synopsis
  • The PHARLAP trial tested an open lung ventilation strategy against control ventilation for ARDS patients, finding no significant difference in ventilator-free days (VFDs) or mortality rates.
  • A parsimonious model identified patients as hypo-inflammatory or hyper-inflammatory, revealing that those with the hypo-inflammatory phenotype had more VFDs compared to their hyper-inflammatory counterparts.
  • The study found that hyper-inflammatory patients had notably fewer VFDs when managed with open lung ventilation versus control ventilation, highlighting the importance of patient phenotype in treatment outcomes.

Background Postacute sequelae of COVID-19 (PASC) and HIV are both associated with reduced exercise capacity, but whether SARS-CoV-2 or PASC are associated with exercise capacity among people with HIV (PWH) is unknown. We hypothesized that PWH with PASC would have reduced exercise capacity from chronotropic incompetence. Methods and Results We conducted cross-sectional cardiopulmonary exercise testing within a COVID recovery cohort that included PWH with and without prior SARS-CoV-2 infection and people without HIV with prior SARS-CoV-2 infection (controls).
