Could structural changes in the retinal layers be a new biomarker of mental disorders? A systematic review and thematic synthesis.
2019
It has recently been suggested that alterations of the layers of the retina could be a biomarker of specific mental disorders since they originate in the same embryonic layer as the brain and both are interconnected through the optic nerve. The purpose of this article is to offer a systematic review of the literature and a thematic synthesis on the current state of the alterations of the retina layers identified by optical coherence tomography in patients with schizophrenia, bipolar disorder and major depression. For this purpose, we performed a bibliographic search, a systematic review of the studies and a thematic synthesis of the reported findings. Patients with schizophrenia have more a…
The effects of reward and frustration in patients with bipolar disorder: Evidence from a computerized task with non-contingent feedback.
2021
Abstract Background: Bipolar disorder (BD) is characterized by mood changes that implies alterations in reward sensitivity and frustration tolerance. This study examined the effects of monetary reward and frustration on attentional performance and on affective experience across mood states in BD. Methods: An Affective Posner Task in which the nature of contingencies are divided in the three successive blocks (baseline condition, monetary reward and non-contingent feedback) was applied to BD individuals in their different episodes: mania (n = 30), depression (n = 30), and euthymia (n = 30) as well as to a group of healthy controls (n = 30). Results: Monetary reward improved performance (in …
Glucose regulation and pain in older people-The Helsinki Birth Cohort Study
2021
Aims: To assess if individuals with diabetes or prediabetes report more pain or have increased use of pain medication compared to normoglycaemic individuals. Methods: Using cross-sectional data, we studied 928 men and 1075 women from the Helsinki Birth Cohort Study in 2001-2004 at a mean age of 61.5 years. Glucose regulation was assessed with a 2-h 75 g oral glucose tolerance test, and applying World Health Organization criteria, participants were defined as having normoglycaemia, prediabetes (impaired fasting glucose or impaired glucose tolerance), newly diagnosed diabetes or previously diagnosed diabetes. Self-reported pain intensity and interference during the previous 4 weeks was estima…
The effects of cold and glucagon on lipolysis, glycogenolysis and oxygen consumption in young chicks.
1973
Abstract 1. 1. To study the possible role of glucagon in avian thermoregulation the effects of cold exposure and glucagon on lipolysis, glycogenolysis and oxygen consumption were measured in young chicks. 2. 2. Cold exposure (+10°C) and glucagon injection (0·3 mg/kg, i.p. at +30°C) both caused a marked increase in the plasma FFA and a decrease in the liver glycogen content. 3. 3. It is suggested that glucagon possibly acts in the avian thermoregulation by producing at least lipolysis and glycogenolysis during cold exposure.
Psychological distress and quality of life in ostomy patients with colorectal cancer: A systematic review of the literature
2018
Introduction: This research examine the literature related to the psychological state and the quality of life in patients with colorectal cancer. In particular, this study investigates the alterations in patients who have undergone ostomy procedures (colostomy and/or ileostomy). Materials and methods: A systematic research was been carried out through the electronic databases PubMed and Psychinfo. After having identified 1289 scientific articles, a convenient sample of 12 studies were included in the research. Overall, all studies taken into analyses have shown how enterostomy affects the quality of life of stoma patients both after the formation of the stoma and the follow-up. Results: 12 …
MitoKATP-channel opener protects against neuronal death in rat venous ischemia.
2005
OBJECTIVE: Mitochondrial adenosine triphosphate-dependent potassium (mitoK ATP ) channels are present in the brain, and several reports have shown their neuroprotective, preconditioning effect against an ischemic insult. The role of mitoK ATP channels in the penumbra area has not been studied thoroughly. In a model of venous ischemia, widespread penumbra-like low flow areas are created, which are susceptible to cortical spreading depression. Thus, we studied effects of mitoK ATP channels on infarct size in this model. METHODS: Male Wistar rats were subjected to two-vein occlusion by photochemical thrombosis of two adjacent cortical veins combined with KCI-induced cortical spreading depressi…
Perfi les Fenomenológicos de Evocación Autobiográfica en Individuos con Depresión
2017
Autobiographical memories are deeply linked with emotional regulation processes and self-concept. Conversely, in case of affective disorders, the access to specific phenomenological components would be impaired. Intentional non-probabilistic sampling was carried out, involving 94 individuals with major depression and 188 healthy individuals in the city of Buenos Aires, Argentina. The phenomenological components of significant autobiographical recollections were contrasted, considering their quantity and intensity. In addition, the depressive individuals' performances were compared according to the presence or absence of previous depressive episodes, psychopharmacological treatment and sever…
15-years mortality in asthma-COPD overlap syndrome (ACOS) elderly population
2015
Background: The coexistence of asthma and chronic obstructive pulmonary disease (Asthma-COPD Overlap Syndrome: ACOS) is increasingly recognized. Data about the prevalence of ACOS in the elderly and its prognostic implications are unknown. Aim: To evaluate the long-term mortality of ACOS in an elderly population. Methods: 1970 subjects, aged >65 yrs, were enrolled in the population-based SA.R.A. Study. ACOS was defined as: not fully reversible airflow limitation + a) history of asthma or b) very positive bronchodilator test (increase in FEV1 ≥15% and ≥400 ml) + atopy + weezing. The prevalence of ACOS and 15-years mortality rates were assessed in 1063 subjects with complete clinical, lung fun…

Predictors of Psychological Distress and Coronavirus Fears in the First Recovery Phase of the Coronavirus Disease 2019 Pandemic in Germany
2021
Objectives: While previous research has mainly focused on the impact of the first acute phase of the COVID-19 pandemic on mental health, little empirical knowledge exists about depression, anxiety, and somatic symptom levels and possible predictors of symptom levels in the pandemic’s recovery phase. The present study aimed to analyze the mental burden of a convenience ample of the general German population during the first recovery phase of the pandemic and to identify significant predictors of symptom levels.Methods: Standardized measures of anxiety (GAD-2), depression (PHQ-2), somatic symptoms (PHQ-15), and health anxiety, as well as measures of COVID-19 fears and possible vulnerability f…
