Aim: Chronic kidney disease (CKD) is one of the major complication from non-communicable diseases (NCD), such as diabetes or hypertension. We aimed to determine if routine measurement of neutrophil gelatinase-associated lipocalin (NGAL) in NCD patients could provide additional benefit for diagnosing kidney disease.

Methods: Fasting serum NGAL, urea, creatinine, uric acid and albumin were measured in 298 NCD patients. Estimated glomerular filtration rate (e-GFR) was calculated using the CKD-EPI equation. Multiple linear regression modeling was used for analysis.

Results: CKD patients have the highest levels of NGAL than the other NCD patients (p < 0.001). Although NGAL was significantly related to e-GFR, creatinine, urea and albumin in CKD-patients (p < 0.001) and not in the other NCD patients (p > 0.05), only serum creatinine predicted NGAL levels in CKD-patients (p < 0.001).

Conclusion: NGAL level is best associated with serum creatinine only in patients with CKD and NGAL measurement may not be cost effective as a routine kidney function test in NCD patients in under-resourced economies.

Background: To investigate the effects of 40 Hz high-definition transcranial alternating current stimulation (HD-tACS) on subjective sleep quality and domain-specific cognitive functions in mild neurocognitive disorders due to Alzheimer's disease (NCD-AD).

Method: This study was a double blind, sham-controlled randomized clinical trial. Ninety-nine mild NCD-AD patients were randomly assigned to receive a 4-week course treatment of either 40 Hz HD-tACS, HD transcranial direct current stimulation (HD-tDCS), or sham transcranial current stimulation (HD-tCS).

Occupational therapists (OTs) are among the health care professionals who assist individuals with neurocognitive disorders (NCDs) to engage in self-care and leisure activities in a skilled nursing facility (SNF) environment. OTs use various environmental modifications to help individuals with NCDs engage in various activities (Jensen & Padilla, 2017). Strong evidence has been found to support occupational therapy recommendations and interventions in adapting the physical environment to support person centered care (Gitlin et al.

Background: The advantages of robot-assisted minimally invasive esophagectomy (RA-MIE) over conventional minimally invasive esophagectomy (C-MIE) are unknown. This nationwide large-scale study aimed to compare surgical outcomes between RA-MIE and C-MIE using rigorous propensity score methods, including detailed covariates and relevant outcomes.

Methods: This Japanese nationwide retrospective cohort study included RA-MIE or C-MIE for esophageal malignant tumors performed between October 2018 and December 2019 and registered in the Japanese National Clinical Database.

Article Synopsis
  • The study aimed to identify genomic variations linked to dystonia in the Asian Indian population using next-generation sequencing.
  • A total of 745 individuals were enrolled, and whole exome sequencing (WES) was performed on 267 patients, revealing pathogenic variants in 20.2% of them, including 14 novel variants.
  • The gene THAP1 was found to be the most common associated with dystonia, and factors like multifocal/generalized distribution and family history increased the likelihood of finding positive results from WES.
