Article Synopsis
- Spatial attention bias is the tendency to focus attention on one side of space, influenced by asymmetric dopamine signaling in the brain's striatum.
- The study examined whether methylphenidate (MPH), a dopamine agonist, decreases this spatial bias by improving connectivity between frontal and striatal brain regions in 54 adults.
- Results showed that MPH reduced attention bias by enhancing brain activity in the medial superior frontal gyrus and improving its connectivity with the caudate, helping participants orient towards the neglected side, regardless of their starting bias.
Article Synopsis
- Scientists studied how a medicine called Methylphenidate (MPH) affects the brain's Default Mode Network (DMN), which helps control thinking and behavior.
- They found that taking MPH changed how different parts of the DMN connect with each other and other networks in the brain, which might help reduce impulsive behavior.
- The study showed that MPH creates both increased and decreased connections within the DMN, and these changes are linked to being more or less impulsive.
Diabetes mellitus (DM) is linked to poor clinical outcomes and high mortality in Coronavirus patients. The primary objective of this systematic review was to determine the prevalence, clinical features, glycemic parameters, and outcomes of newly diagnosed diabetes in individuals with COVID-19 in developing and developed countries. By searching PubMed, Medline, Scopus, Embase, Google Scholar, and PakMediNet databases, an online literature search was conducted from March 2020 to November 2021.

Psychiatric morbidity commonly coexists with substance abuse and HIV/AIDS around the globe. This review study aimed to determine the available literature on the prevalence of common substance abuse/use and common mental health illnesses among HIV/AIDS patients worldwide to help policymakers design appropriate strategies to limit extensive substance use and prevent common mental and health illnesses. For the comprehensive literature review, Google Scholar, PubMed Central, Medline, and PakMediNet biomedical databases were searched for original and reviewed studies published in English, from January 2000 to September 2021.

Detection of depression can be improved by introducing short, reliable, and valid screening instruments.
Aim: To determine the psychometric properties of the patient health questionnaire-2 (PHQ-2) and patient health questionnaire-9 (PHQ-9) for depression screening and diagnosis, and the sensitivity and specificity of the PHQ-2 in HIV infected patients.
