Background: There is lack of data on bipolar disorder (BD) type II from India.
Aim: To compare the demographic and clinical characteristics of patients with BD-I and BD-II using the data of the Bipolar Disorder Course and Outcome study from India (BiD-CoIN study).
Methodology: Using the data of the BiD-CoIN study, patients with BD-I and BD-II were compared for demographic and clinical variables.
Article Synopsis
- The study investigates the effects of adding dexmedetomidine as premedication to ketofol for sedation in children undergoing MRI, aiming to improve sedation quality and reduce movement artifacts during scans.
- A total of 132 children aged 6 months to 10 years were divided into two groups: one receiving dexmedetomidine and ketofol (DK group) and the other receiving only ketofol (K group). Results showed that the DK group had significantly better sedation quality and scan quality, along with lower propofol dosage.
- The conclusion indicates that administering dexmedetomidine prior to induction enhances sedation quality, reduces the need for additional propofol, and maintains
Emerging role of electrochemistry in radiochemical separation of medically important radiometals: state of the art.
Am J Nucl Med Mol Imaging
October 2024
Electrochemical separation technology has brought a renaissance in the field of nuclear medicine towards obtaining clinical-grade radiometals for preparation of a wide variety of radiopharmaceuticals. This article is a comprehensive summary of the electrochemical processes developed for the separation of radiometals that could be used for diagnostic or therapeutic applications in nuclear medicine. For using electrochemistry as a tool for the separation of radiometals, intricate knowledge is essential to understand the basic parameters of electrochemical separation processes which include applied potential, selection of electrolyte, choice of the electrode, the temperature of the electrolyte, pH of the electrolyte and time of electrolysis.

- Elderly loneliness in India is a critical public health issue, especially in rural areas, where research has been limited.
- A study of 125 seniors found a high prevalence of loneliness (66.4%), linked to factors such as lack of companionship and isolation.
- Loneliness was positively associated with greater depression and increased caregiver abuse, with single individuals and those from nuclear families reporting higher loneliness levels.
Background: There is a lack of information on the long-term course and outcomes of bipolar disorder (BD) patients with seasonal affective disorder (SAD).
Aim: To compare the demographic and clinical profile of BD patients with and without SAD.
Methodology: Data from 773 BD patients with an illness duration of at least 10 years were collected from 14 tertiary care centers.
