Development and evaluation of a customized checklist to assess the quality control of disease registry systems of Tehran, the capital of Iran in 2021.

Background: Clinical registries facilitate medical research by providing 'real data'. In the past decade, an increasing number of disease registry systems (DRS) have been initiated in Iran. Here, we assessed the quality control (QC) of the data recorded in the DRS established by Shahid Beheshti University of Medical Sciences in Tehran, the capital city of Iran, in 2021.

Language production impairments in patients with a first episode of psychosis.

Language production has often been described as impaired in psychiatric diseases such as in psychosis. Nevertheless, little is known about the characteristics of linguistic difficulties and their relation with other cognitive domains in patients with a first episode of psychosis (FEP), either affective or non-affective. To deepen our comprehension of linguistic profile in FEP, 133 patients with FEP (95 non-affective, FEP-NA; 38 affective, FEP-A) and 133 healthy controls (HC) were assessed with a narrative discourse task.

Executive Functions in panic disorder: A mini-review.

Background: Panic disorder (PD) is an anxiety disorder characterized by recurrent panic attacks whose aetiology might be associated with alterations of the prefrontal-amygdala circuitry. The prefrontal cortex is a key region involved in executive functioning (EF) whose disturbance may imply harsh consequences over personal, social, and working aspects of PD patients. Indeed, defining the real involvement of EF in PD could lead to early assessment, better treatment, and rehabilitation options.

Mental Health in Patients With Adrenal Incidentalomas: Is There a Relation With Different Degrees of Cortisol Secretion?

Context: Cushing's syndrome frequently causes mental health impairment. Data in patients with adrenal incidentaloma (AI) are lacking.

Objective: We aimed to evaluate psychiatric and neurocognitive functions in AI patients, in relation to the presence of subclinical hypercortisolism (SH), and the effect of adrenalectomy on mental health.

Visual exploration of emotional body language: a behavioural and eye-tracking study.

Bodily postures are essential to correctly comprehend others' emotions and intentions. Nonetheless, very few studies focused on the pattern of eye movements implicated in the recognition of emotional body language (EBL), demonstrating significant differences in relation to different emotions. A yet unanswered question regards the presence of the "left-gaze bias" (i.

The Effect of DHA Supplementation on Cognition in Patients with Bipolar Disorder: An Exploratory Randomized Control Trial.

Bipolar disorder (BD) is a severe mental disorder with a wide range of cognitive deficits, both in the euthymic and acute phase of the disease. Interestingly, in recent years, there has been a growing interest in investigating the impact of ω-3 polyunsaturated fatty acids on cognition in BD. In this context, the aim of this study is to evaluate the effect of docosahexaenoic acid (C22:6 ω-3, DHA) supplementation on cognitive performances in euthymic BD patients.

Altered syntactic abilities in first episode patients: An inner phenomenon characterizing psychosis.

Background: Research has consistently shown that language abilities represent a core dimension of psychosis; however, to date, very little is known about syntactic comprehension performance in the early stages of psychosis. This study aims to compare the linguistic abilities involved in syntactic comprehension in a large group of First Episode Psychosis (FEP) patients and healthy controls (HCs).

Methods: A multiple choice test of comprehension of syntax was administered to 218 FEP patients (166 non-affective FEP patients [FEP-NA] and 52 affective FEP patients [FEP-A]) and 106 HCs.

Pancreatic Cancer in Iran: an Epidemiological Review.

Purpose: Pancreatic cancer is the seventh cause of death in men in the world and also is one of the most common malignancies worldwide with poor prognosis. Due to the lack of epidemiological aspects of pancreatic cancer in Iran, this study aimed to investigate the epidemiological aspects of pancreatic cancer in Iran.

Methods: In February 2019, A search was conducted with the keywords "Pancreatic Neoplasm," "Pancreas Neoplasms," "Cancer of Pancreas," "Pancreas Cancer," "Pancreatic Cancer," "Cancer of the Pancreas," and "Iran" in their title or abstract and MeSH.

How context influences the interpretation of facial expressions: a source localization high-density EEG study on the "Kuleshov effect".

Few studies have explored the specificities of contextual modulations of the processing of facial expressions at a neuronal level. This study fills this gap by employing an original paradigm, based on a version of the filmic "Kuleshov effect". High-density EEG was recorded while participants watched film sequences consisting of three shots: the close-up of a target person's neutral face (Face_1), the scene that the target person was looking at (happy, fearful, or neutral), and another close-up of the same target person's neutral face (Face_2).

Beholders' sensorimotor engagement enhances aesthetic rating of pictorial facial expressions of pain.

The present study addresses a novel issue by investigating whether beholders' sensorimotor engagement with the emotional content of works of art contributes to the formation of their objective aesthetic judgment of beauty. To this purpose, participants' sensorimotor engagement was modulated by asking them to overtly contract the Corrugator Supercilii facial muscles or to refrain from any voluntary facial movement while judging the aesthetic value of painful and neutral facial expressions in select examples of Renaissance and Baroque paintings. Results demonstrated a specific increase in the aesthetic rating of paintings showing painful facial expressions during the congruent activation of the Corrugator Supercilii muscles.

Behavioral and autonomic responses to real and digital reproductions of works of art.

Nowadays, works of art can be enjoyed in both their original and reproduced format. The aim of this study was to investigate whether the format of a work of art could influence physiological and cognitive responses in beholders. Two abstract works of art and their digital reproductions were selected as experimental stimuli and displayed for 2min to 60 participants in a museum.

How Context Influences Our Perception of Emotional Faces: A Behavioral Study on the Kuleshov Effect.

Facial expressions are of major importance in understanding the mental and emotional states of others. So far, most studies on the perception and comprehension of emotions have used isolated facial expressions as stimuli; for example, photographs of actors displaying facial expressions corresponding to one of the so called 'basic emotions.' However, our real experience during social interactions is different: facial expressions of emotion are mostly perceived in a wider context, constituted by body language, the surrounding environment, and our beliefs and expectations.

Comparison of clinical-metabolic monitoring and outcomes and coronary risk status in people with type 2 diabetes from Australia, France and Latin America.

Aim: To compare clinical-metabolic monitoring and coronary risk status in people with type 2 diabetes from Australia, France and Latin America.

Methods: Retrospective analysis of data collected at primary care (except ANDIAB--secondary care) [corrected] matched for age, gender and disease duration.

Changes in collagenase and collagen gene expression after induction of aortocaval fistula in rats.

Progressive ventricular dilatation commonly accompanies the transition to overt failure in chronically overloaded hearts; however, only recently have studies begun to elucidate underlying molecular alterations. In particular, the potential role of altered myocardial expression of the procollagenase gene in this process has not previously been examined. Biventricular hypertrophy and dilatation were produced in rats by creating an abdominal aortocaval fistula.

Gated magnetic resonance imaging of normal and hypertrophied murine hearts.

Transgenic murine models are being used increasingly to explore the molecular basis of heart disease. Until recently, there were no means for noninvasive assessment of changes in mass and function of the murine heart because of its very small size and high heart rate. Transthoracic echocardiography has now been utilized to obtain noninvasive estimates of murine left ventricular (LV) wall thicknesses, internal dimension, and mass.

Prolonged ejection duration helps to maintain pump performance of the renal-hypertensive-diabetic rat heart: correlations between isolated papillary muscle function and ventricular performance in situ.

Objective: The purpose of this study was to examine the degree to which mechanical alterations in left ventricular papillary muscles of renal hypertensive-diabetic rat hearts correlate with functional measurements made on the same hearts in situ.

Methods: Female Wistar rats weighing 170-200 g were made hypertensive by placing a 0.24 mm clip on the left renal artery, and made diabetic 1 week later by a single intravenous injection of streptozotocin (60 mg/kg).

Intravascular Ultrasound Catheter Evaluation of the Left Ventricle in Mice: A Feasibility Study.

With the advent of transgenic technology, it has become increasingly important to find a method for evaluating left ventricular (LV) anatomy and function in intact wild type, intervened, and transgenic mice. Mice are 1/10th the size of rats, and have body masses of 10-60 g, LV masses of 40-150 mg, LV wall thicknesses of 0.5-2 mm, and LV internal dimensions of 1-3 mm.

Effects of hypertrophy and heart failure on [Na+]i in pressure-overloaded guinea pig heart.

Intracellular free sodium levels ([Na+]i) were assessed with 23Na nuclear magnetic resonance (NMR) spectroscopy in isolated, Langendorff-perfused normal, compensated hypertrophied, and hypertrophied failing guinea pig hearts under several conditions. Baseline [Na+]i measured with a shift reagent was significantly greater than normal in the compensated hypertrophied hearts (12.8 +/- 1.

Echocardiographic assessment of left ventricular mass and systolic function in mice.

The increasing use of transgenic mouse models for investigating the mechanisms of cardiac growth and function has made it important to develop noninvasive methods for assessing murine cardiac anatomy, size, and function. At present, murine cardiac mass can be determined only at necropsy. Left ventricular (LV) function can be assessed by use of various catheterization techniques, but these approaches are usually terminal procedures and provide no information about chamber anatomy and dimensions.

Reduced calcium current density in single myocytes isolated from hypertrophied failing guinea pig hearts.

The present study explored the possibility that an alteration in the transmembrane calcium current (ICa), through its ability to modulate Ca2+ release from the sarcoplasmic reticulum, could contribute to the depressed peak [Ca2+]i we previously observed in hypertrophied failing myocardium. Whole-cell patch clamp was used to measure ICa in single guinea pig ventricular myocytes isolated from hearts of normal guinea pigs and from guinea pig hearts in which hypertrophy and failure were induced by gradually developing left ventricular pressure overload subsequent to ascending aortic banding of young animals. Membrane capacitance (Cm) was significantly greater.
