There has been an increasing interest in neurobiological correlates of psychopathology with a growing consensus that such research questions are best investigated through dimensional approaches to psychopathology. One area that has been noticeably understudied in this regard is eating pathology. Therefore, the goal of the current systematic review was to summarize research on structural brain correlates of symptom dimensions of eating-related pathology. Google Scholar and PubMed databases were searched following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Results suggest that restrained eating is associated with increased GMV (gray matter volume) in regions involved in emotional, visuo-spatial, attentional, and self-related processing. Disinhibitory eating is associated with increased GMV in regions involved in reward value of food-related stimuli and decreased GMV in regions involved in emotional/motivational processing. All told, results suggest that dimensions of eating pathology have differential neuroanatomical correlates potentially suggesting differences in neural pathways which has the potential to support future biologically-driven classification and treatment efforts.

Article Synopsis
- Non-neoplastic hypercortisolaemia, or pseudo-Cushing's syndrome (PCS), can occur due to various health conditions like depression, obesity, and diabetes, linked to overactivity of the hypothalamic-pituitary-adrenal axis.
- A 66-year-old woman exhibited symptoms such as weakness, weight loss, and poorly controlled hypertension, which led to the discovery of pheochromocytoma, a tumor that causes hormone overproduction, upon further testing.
- After undergoing surgery to remove the tumor and receiving supportive treatment, her symptoms improved significantly, confirming the diagnosis of PCS rather than traditional Cushing's syndrome.

Background: Anorexia nervosa (AN) is a polygenic, severe metabopsychiatric disorder with poorly understood aetiology. Eight significant loci have been identified by genome-wide association studies (GWAS) and single nucleotide polymorphism (SNP)-based heritability was estimated to be ~ 11-17, yet causal variants remain elusive. It is therefore important to define the full spectrum of genetic variants in the wider regions surrounding these significantly associated loci.

Paratuberculosis is an infectious disease caused by subspecies (MAP). Typically, ruminant animals including cattle, buffalo, goats, and sheep are infected with MAP. Animals get infected with MAP in a number of ways, such as by eating or drinking contaminated food or water, or by nursing from an infected mother who may have contaminated teats or directly shed the organism in milk or colostrum.

The free-living amoeba (NF) causes a rare but lethal parasitic meningoencephalitis (PAM) in humans. Currently, this disease lacks effective treatments and the specific molecular mechanisms that govern NF pathogenesis and host brain response remain unknown. To address some of these issues, we sought to explore naturally existing virulence diversity within environmental NF isolates.
