AI Article Synopsis

  • The study took place at Bowring and Lady Curzon Hospital in Bangalore, focusing on the bidirectional screening of tuberculosis (TB) and diabetes mellitus (DM).
  • The research involved assessing all TB patients for DM and vice versa over a six-month period, revealing that 6.3% of TB patients were previously diagnosed with DM, while additional screening identified more cases of pre-diabetes and DM.
  • The conclusion highlights that screening for DM in TB patients is effective, though the detection rate of TB in DM patients was low, suggesting the need for improved diagnostic methods in future studies.

Article Abstract

Setting: Tuberculosis (TB) and diabetes mellitus (DM) clinics at Bowring and Lady Curzon Hospital, a tertiary care centre in Bangalore, India.

Obejctive: To assess the feasibility and results of TB-DM bidirectional screening.

Methods: A descriptive study conducted from 1 March to 30 September 2012, in which all TB patients were assessed for DM and vice versa. Fasting blood glucose values of ≥126 mg/dl and 110-125 mg/dl were considered as DM and pre-diabetes, respectively.

Results: Of 510 TB patients, 32 (6.3%) had been previously diagnosed with DM. Screening among the remaining 478 patients yielded 15 (2.9%) with pre-diabetes and 15 (2.9%) newly diagnosed cases of DM. A higher prevalence of DM was found among patients aged ≥40 years, patients with pulmonary TB and smokers. Of the 47 TB-DM patients, 45 were enrolled in DM care. Of 1670 DM patients followed up in DM clinics, 45 already had TB. Among the remaining 1625 patients screened, 152 (9%) had symptoms suggestive of TB; two of these were found to have the disease.

Conclusion: Bidirectional screening for DM and TB is feasible and produces a high yield for DM among TB patients. The yield of TB among DM patients was low and needs future research using new, improved TB diagnostic tools.

Background: Manual extraction of real-world clinical data for research can be time-consuming and prone to error. We assessed the feasibility of using natural language processing (NLP), an AI technique, to automate data extraction for patients with advanced lung cancer (aLC). We assessed the external validity of our NLP-extracted data by comparing our findings to those reported in the literature.

Objectives: The lack of definitive biomarkers presents a significant challenge for chemo-immunotherapy in extensive-stage small-cell lung cancer (ES-SCLC). We aimed to identify key genes associated with chemo-immunotherapy efficacy in ES-SCLC through comprehensive gene expression analysis using machine learning (ML).

Methods: A prospective multicenter cohort of patients with ES-SCLC who received first-line chemo-immunotherapy was analyzed.

Introduction: The use of taxanes in the adjuvant setting of early breast cancer (BC) confers survival benefits, however, their role in older patients merits further study. This retrospective pooled analysis of randomized controlled trials conducted by the Hellenic Oncology Research Group (HORG) aims to assess the efficacy and safety of taxane-based adjuvant chemotherapy in older women with BC.

Materials And Methods: Five phase III trials containing a taxane, conducted by HORG between 1995 and 2013, were included in a patient-data pooled analysis.

November 2024

Clinical Research, Drug Development Division, Sumitomo Pharma Co., Ltd., 33-94, Enoki-cho, Suita, Osaka, 564-0053, Japan. Electronic address:

The second-generation antipsychotic blonanserin is a highly selective, full antagonist of dopamine D and D and serotonin 5-HT receptors. It is currently prescribed for patients with schizophrenia in Japan. We aimed to develop a population pharmacokinetic model of oral blonanserin, including data from 12 to 77 years old patients, to assess the covariates that influence blonanserin pharmacokinetics and evaluate appropriate dosage regimens in adolescents versus adults.
