There is growing interest in assessing affective temperaments in relation to major depressive disorder (MDD) and bipolar disorder (BD). Needed is evaluation of the impact of temperament ratings on responses to treatment of depression in these disorders. We measured treatment response as %-improvement in HDRS depression ratings and correlated this measure as well as response rate (≥50 % improvement) with TEMPS-A ratings of anxious, cyclothymic, dysthymic, hyperthymic, and irritable affective temperaments in 2264 mood-disorder patients (1165 BD, 1099 MDD; 62.

Article Synopsis
  • Bipolar disorder (BD) is a complex mental health condition, and researchers aimed to identify a neurodevelopmental phenotype (NDP) that contributes to its development and impacts clinical outcomes.
  • By analyzing data from over 4,400 BD patients, they established nine specific clinical features that characterize this NDP, which are linked to poorer prognosis and treatment responses.
  • The findings suggest that patients with a higher NDP load may have overlapping genetic factors with ADHD, indicating a potential shared biological basis for these disorders.

Background: Anticipating diagnostic change from major depressive (MDD) to bipolar disorder (BD) can support better prognosis and treatment, especially of depression but is challenging and reported research results are inconsistent. We therefore assessed clinical characteristics associated with diagnostic change from MDD to BD with antidepressant treatments.

Methods: We compared characteristics of 3212 initially MDD patients who became (hypo)manic during antidepressant treatment to those with stable MDD diagnoses as well as with cases of stable, spontaneous BD, using standard bivariate and multivariate statistics.

Scabies is an important skin disease in several species of domestic and wild animals; however, few reports in Brazil have emphasized its occurrence in buffaloes. This article describes the epidemiological, clinical and pathological aspects and diagnosis of psoroptic mange in buffaloes in a property in the municipality of Castanhal, PA, Amazon region. Of the 41 buffaloes examined, 38 males and females of the Murrah, Baio, Mediterranean and Carabao breeds and their crossbreeds, aged between 2 and 20 years, had a history of pruritus.

Background: Lithium is effective in the long-term treatment of bipolar disorder. Concerns have been raised about non-responsiveness after discontinuation and resuming previously effective lithium prophylaxis. We reviewed the available literature on this so-called lithium-discontinuation-induced treatment refractoriness (LDITR).

Article Synopsis
  • - This study aimed to see if bipolar disorder (BD) patients' clinical profiles could be better differentiated by diagnostic subtype or by how they respond to lithium treatment.
  • - Researchers analyzed 477 adult BD patients treated with lithium for at least a year, using various clinical features to create clusters that reflected treatment responses and BD subtypes.
  • - The results indicated that the clusters provided more insight into lithium responsiveness than BD subtype, with a smaller cluster containing a higher percentage of lithium responders, suggesting that treatment response could be a more effective way to categorize these patients.

In recent years, several studies described the close relationship between the composition of gut microbiota and brain functions, highlighting the importance of gut-derived metabolites in mediating neuronal and glial cells cross-talk in physiological and pathological condition. Gut dysbiosis may affects cerebral tumors growth and progression, but the specific metabolites involved in this modulation have not been identified yet. Using a syngeneic mouse model of glioma, we have investigated the role of dysbiosis induced by the administration of non-absorbable antibiotics on mouse metabolome and on tumor microenvironment.

  • - Meningitis is an inflammation of the membranes around the central nervous system, and its manifestation in water buffaloes has been inadequately documented; five cases of the condition were examined in adult Murrah and Mediterranean breed buffaloes from Castanhal, Brazil.
  • - Clinical signs included neurological symptoms such as lethargy, difficulty moving, and convulsions; significant findings included loss of horn material, bloody discharge from the frontal sinus, and a notable increase in neutrophils in blood tests.
  • - Necropsy revealed severe adherence of the dura mater, presence of purulent exudate on the brain and spinal cord, and cloudy cerebrospinal fluid, confirming a diagnosis of bacterial fibrinopurulent meningitis

It has been suggested that substance use disorders could lead to accelerated biological aging, but only a few neuroimaging studies have investigated this hypothesis so far. In this cross-sectional study, structural neuroimaging was performed to measure cortical thickness (CT) in tricenarian adults with cocaine use disorder (CUD, n  = 30) and their age-paired controls (YC, n  = 30), and compare it with octogenarian elder controls (EC, n  = 20). We found that CT in the right fusiform gyrus was similar between CUD and EC, thinner than the expected values of YC.

Early abuse has been associated with psychiatric morbidity but comparisons of bipolar (BD) and major depressive (MDD) disorder subjects with versus without early sexual or physical abuse are rare. Patients (n = 684) diagnosed with a DSM-5-TR major mood disorder were evaluated and followed for several years at mood disorder centers to compare details of history and clinical status in participants with versus without early sexual or physical abuse. Early history of sexual (16.

Understanding the complexities of the human brain and its associated disorders poses a significant challenge in neuroscience. Traditional research methods have limitations in replicating its intricacies, necessitating the development of in vitro models that can simulate its structure and function. Three-dimensional in vitro models, including organoids, cerebral organoids, bioprinted brain models, and functionalized brain organoids, offer promising platforms for studying human brain development, physiology, and disease.

Learning Objectives After Participating In This Cme Activity, The Psychiatrist Should Be Better Able To: • Analyze and compare the different bipolar disorder (BD) types.• Identify markers that distinguish BD types and explain how the DSM-IV defines the disorder.

Abstract: Since the status of type II bipolar disorder (BD2) as a separate and distinct form of bipolar disorder (BD) remains controversial, we reviewed studies that directly compare BD2 to type I bipolar disorder (BD1).

Article Synopsis
  • Sunlight helps our skin make vitamin D through UVB radiation, but some places don't get enough UVB in winter, which can affect brain health.
  • A study looked at 6,972 people with bipolar I disorder from over 70 countries to see if not getting enough UVB was related to when they first had symptoms.
  • The results suggested that people in areas with less UVB tended to show symptoms of bipolar disorder about 1.66 years earlier, but more research is needed to understand the role of vitamin D and UVB in this condition.

Background: Rapid-cycling (RC; ≥ 4 episodes/year) in bipolar disorder (BD) has been recognized since the 1970s and associated with inferior treatment response. However, associations of single years of RC with overall cycling rate, long-term morbidity, and diagnostic subtypes are not clear.

Results: We compared descriptive and clinical characteristics in 1261 BD patients with/without RC, based on history and prospective follow-up for several years.

Antidepressant-induced mania (AIM) is a side effect of antidepressant treatment that is characterized by mania or hypomania after the start of medication. It is likely polygenic, but its genetic component remains largely unexplored. We aim to conduct the first genome-wide association study of AIM in 814 bipolar disorder patients of European ancestry.

Background: Lithium is the gold standard prophylactic treatment for bipolar disorder. Most clinical practice guidelines recommend regular calcium assessments as part of monitoring lithium treatment, but easy-to-implement specific management strategies in the event of abnormal calcium levels are lacking.

Methods: Based on a narrative review of the effects of lithium on calcium and parathyroid hormone (PTH) homeostasis and its clinical implications, experts developed a step-by-step algorithm to guide the initial management of emergent hypercalcemia during lithium treatment.
