Female sexual dysfunction (FSD) is a public health problem that affects women's quality of life. Although the relationship between some hormones and the FSD has been described, it is not well established for all hormones. Therefore, the aim of our study was to evaluate the association between hormonal dysfunction and sexual dysfunction in premenopausal women. We performed a cross-sectional study with 60 patients with regular menstrual cycles, with age ranging from 18 to 44 years, with previous diagnosis of FSD...

OBJECTIVE: The management of and prognosis for delirium are affected by its subtype: hypoactive, hyperactive, mixed, and none. The DMSS-4, an abbreviated version of the Delirium Motor Symptom Scale, is a brief instrument for the assessment of delirium subtypes. However, it has not yet been evaluated in an intensive care setting. METHOD: We performed a prospective/descriptive cohort study in order to determine the internal consistency, reliability, and validity of the relevant items of the DMSS-4 versus the Delirium Rating Scale-Revised-98 (DRS-R-98) and the original DMSS in a surgical intensive care setting...

BACKGROUND: Advances in cardiac surgery has shifted paradigm of management to perioperative psychological illnesses. Delirium is a state of altered consciousness with easy distraction of thoughts. The pathophysiology of this complication is not clear, but identification of risk factors is important for positive postoperative outcomes. The goal of the present study was to prospectively identify the incidence, motoric subtypes, and risk factors associated with development of delirium in cardiac surgical patients admitted to postoperative cardiac intensive care, using a validated delirium monitoring instrument...

BACKGROUND: Patients with major depressive disorder (MDD) exhibit cognitive impairment, and evidence suggests that the semantic version of the verbal fluency task is a reliable cognitive marker of the disorder. Here, using functional magnetic resonance imaging (fMRI), we investigated the dysfunction of neural processing in acute depression and examined the effects of a 6-week pharmacological intervention. METHODS: Sixteen patients with MDD participated in 2 fMRI sessions, and 16 healthy control (HC) subjects participated in 1 fMRI session...

INTRODUCTION: Counts of satisfying sexual events (SSEs) per month have been criticized as an end point in treatment trials of women with hypoactive sexual desire disorder (HSDD) but grounding improvement in sexual desire by assessing changes in sexual behavior remains of some importance. METHODS: We conducted a literature review to find validated measurements that are specific sexual behavioral correlates of low sexual desire. We compared expert-proposed criteria for dysfunctional desire, expert-developed sets of scale items, and self-rated scales developed before issuance of, or in accordance with, the Food and Drug Administration's guidance on developing patient-reported outcomes...

Atrazine (ATR) is an herbicide broadly used in the world to control weeds in corn and sorghum fields, and it is potentially toxic for the dopaminergic system. Alterations in dopaminergic markers after ATR administration in rats and C57BL/6 mice have been reported. Behaviorally, it has been observed that ATR exposure causes hypoactivity shortly after its administration. To understand how acute ATR administration induces hypoactivity, we set out to map the brain areas responsive to ATR using c-Fos as a marker of neuronal activity, and tyrosine hydroxylase (TH) as a marker of dopaminergic neurons...

Hemopressin and related peptides have shown to function as the endogenous ligands or the regulator of cannabinoid receptors. Moreover, hemopressin and its truncated peptides were also reported to produce a slight modulatory effect on opioid system. In the present work, based on the amino acid sequence analyses of hemoglobin subunit α, rat VD-hemopressin(α) [(r)VD-Hpα] was predicted as a cannabinoid peptide derived from rat α-hemoglobin. Furthermore, (r)VD-Hpα was synthesized and characterized in a series of in vitro and in vivo assays...

Mental functions involve coordinated activities of specific neuronal ensembles that are embedded in complex brain circuits. Aberrant neuronal ensemble dynamics is thought to form the neurobiological basis of mental disorders. A major challenge in mental health research is to identify these cellular ensembles and determine what molecular mechanisms constrain their emergence and consolidation during development and learning. Here, we provide a perspective based on recent studies that use activity-dependent gene Arc/Arg3...

Cyclin-dependent kinase-like 5 (CDKL5) mutations are found in severe neurodevelopmental disorders, including the Hanefeld variant of Rett syndrome (RTT; CDKL5 disorder). CDKL5 loss-of-function murine models recapitulate pathological signs of the human disease, such as visual attention deficits and reduced visual acuity. Here we investigated the cellular and synaptic substrates of visual defects by studying the organization of the primary visual cortex (V1) of Cdkl5(-/y) mice. We found a severe reduction of c-Fos expression in V1 of Cdkl5(-/y) mutants, suggesting circuit hypoactivity...

Delirium describes a sudden onset change in mental status of fluctuating course. This is a state of altered consciousness characterised chiefly by inattention or lack of arousal, but can also include new impairment of language, perception and behaviour. Certain predisposing factors can make an individual more susceptible to delirium in the face of a stressor. Stressors include direct insults to the brain, insults peripheral to the brain or external changes in the environment of an individual. Delirium is varied in its presentation, and can be categorised by the psychomotor profile as: hyperactive type (overly vigilant, agitated, often wandersome), hypoactive type (sedate or withdrawn) or mixed types...

Traumatic brain injury (TBI) initiates a cascade of pathophysiological changes that are both complex and difficult to treat. Progesterone (P4) is a neuroprotective treatment option that has shown excellent preclinical benefits in the treatment of TBI but these benefits have not translated well in the clinic. We have previously shown that P4 exacerbates the already hypoactive upper cortical responses in the short-term post-TBI and does not reduce upper cortical hyper-activity in the long-term, and we concluded that there is no tangible benefit to sensory cortex firing strength...

The management of higher brain dysfunctions such as stroke-induced unilateral spatial neglect (USN) or aphasia is crucial because these dysfunctions have devastating neurological repercussions on the patients' daily life and quality of life. Impairment of the physiological interhemispheric rivalry is often the result of brain insults such as strokes or traumatic injuries, and it may lead to USN or aphasia. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation method, is a promising tool for restoring the pathological imbalance in interhemispheric rivalry by either suppressing the hyperactivity of the unaffected hemisphere or facilitating hypoactivity in the affected hemisphere...

INTRODUCTION: The brain has two goals: survival of the individual and survival of the species. It ensures that the body resides in safe circumstances and can obtain sufficient drink and food. It also has to produce and protect offspring. Its most important tool is its motor system, which consists of the voluntary and emotional motor systems. AIM: To explain how the brain uses its emotional motor system to control the pelvic organs. METHODS: Anatomic and physiologic data in cats and humans are used to find out how this motor system works and what parts of the brain and brainstem are involved...

INTRODUCTION: Hypoactive Sexual Desire Disorder (HSDD) is defined in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Revised (DSM-IV-TR) as persistent deficient sexual fantasies and desire for sexual activity that causes marked distress or interpersonal difficulty. In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), HSDD has been subsumed by Female Sexual Interest/Arousal Disorder. However, decades of research based on DSM-IV-TR HSDD criteria form the foundation of our understanding of the essential symptom of distressing low sexual desire, its epidemiology, clinical management, and treatment...
