The diagnostic utility of inducer and inhibitor based assays among 214 AmpC positive isolates of Pseudomonas aeruginosa were evaluated. Of different methods, combination of ceftazidime-imipenem antagonism and boronic acid inhibition tests came up with maximum sensitivity (76%) and specificity (100%). This combination showed reliability for both inducible and non-inducible AmpC producers.

External Validation of the Walter Index for Posthospitalization Mortality Prediction in Older Adults.
JAMA Netw Open
January 2025
Division of Geriatrics, School of Medicine, University of California San Francisco.
Importance: The Walter Index is a widely used prognostic tool for assessing 12-month mortality risk among hospitalized older adults. Developed in the US in 2001, its accuracy in contemporary non-US contexts is unclear.
Objective: To evaluate the external validity of the Walter Index in predicting posthospitalization mortality risk in Brazilian older adult inpatients.
Cerebral Microbleeds and Amyloid Pathology Estimates From the Amyloid Biomarker Study.
JAMA Netw Open
January 2025
Alzheimer Center Limburg, Department of Psychiatry and Neuropsychology, School for Mental Health and Neuroscience, Maastricht University, Maastricht, the Netherlands.
Importance: Baseline cerebral microbleeds (CMBs) and APOE ε4 allele copy number are important risk factors for amyloid-related imaging abnormalities in patients with Alzheimer disease (AD) receiving therapies to lower amyloid-β plaque levels.
Objective: To provide prevalence estimates of any, no more than 4, or fewer than 2 CMBs in association with amyloid status, APOE ε4 copy number, and age.
Design, Setting, And Participants: This cross-sectional study used data included in the Amyloid Biomarker Study data pooling initiative (January 1, 2012, to the present [data collection is ongoing]).
Polygenic Risk Score Added to Conventional Case Finding to Identify Undiagnosed Chronic Obstructive Pulmonary Disease.
JAMA
January 2025
Channing Division of Network Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts.
Importance: Chronic obstructive pulmonary disease (COPD) is often undiagnosed. Although genetic risk plays a significant role in COPD susceptibility, its utility in guiding spirometry testing and identifying undiagnosed cases is unclear.
Objective: To determine whether a COPD polygenic risk score (PRS) enhances the identification of undiagnosed COPD beyond a case-finding questionnaire (eg, the Lung Function Questionnaire) using conventional risk factors and respiratory symptoms.
Conventional periodontal probing versus salivary biomarkers in diagnosis and evaluation of chronic periodontitis in type 2 diabetes mellitus.
Minerva Dent Oral Sci

Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences (SIMATS), Saveetha University, Chennai, India -
Chronic periodontitis is a prevalent inflammatory condition that affects both the oral health and systemic well-being of individuals, particularly those with type 2 diabetes mellitus (T2DM). Accurate diagnosis and evaluation of periodontal status are crucial for effective management of the disease. This narrative review aimed to compare the diagnostic and evaluative capabilities of conventional periodontal probing and salivary biomarkers in chronic periodontitis among individuals with T2DM.

Cancer J
January 2025
From the Department of Radiation Oncology, Massachusetts General Hospital, Boston, MA.
Purpose: Chemoradiation-induced lymphopenia is common and associated with poorer survival in multiple solid malignancies. However, the association between chemoradiation-related lymphopenia and survival outcomes in rectal cancer is yet unclear. The objective of this study was to evaluate the prognostic impact of lymphopenia and its predictors in patients with rectal cancer undergoing neoadjuvant chemoradiation.
