Assessment of maximal handgrip strength: How many attempts are needed?
2017
BACKGROUND: Handgrip strength (HGS) is used to identify individuals with low muscle strength (dynapenia). The influence of the number of attempts on maximal HGS is not yet known and may differ depending on age and health status. This study aimed to assess how many attempts of HGS are required to obtain maximal HGS.METHODS: Three cohorts (939 individuals) differing in age and health status were included. HGS was assessed three times and explored as continuous and dichotomous variable. Paired t-test, intraclass correlation coefficients (ICC) and Bland-Altman analysis were used to test reproducibility of HGS. The number of individuals with misclassified dynapenia at attempts 1 and 2 with respe…
Functional connectivity of major depression disorder using ongoing EEG during music perception
2020
Abstract Objective The functional connectivity (FC) of major depression disorder (MDD) has not been well studied under naturalistic and continuous stimuli conditions. In this study, we investigated the frequency-specific FC of MDD patients exposed to conditions of music perception using ongoing electroencephalogram (EEG). Methods First, we applied the phase lag index (PLI) method to calculate the connectivity matrices and graph theory-based methods to measure the topology of brain networks across different frequency bands. Then, classification methods were adopted to identify the most discriminate frequency band for the diagnosis of MDD. Results During music perception, MDD patients exhibit…
Psychopathological predictors of suicide in patients with major depression during a 5-year follow-up.
2001
SummaryObjective. It is widely known that the risk of suicide is higher in cases of major depressive disorders in comparison to the general population. The purpose of this study was to examine which psychopathologic symptoms during the index episode are predictors for an increased risk of suicide in the further course of major depression.Method. Mortality data were determined from a prospective study of 280 patients with major depression (DSM-III-R, single episode or recurrent) during a follow-up period of 5 years. The predictive power of different depressive symptoms including psychotic symptoms for suicide risk was investigated.Results.Patients who committed suicide(N = 16)during the foll…
Alterations in the expression of PSA-NCAM and synaptic proteins in the dorsolateral prefrontal cortex of psychiatric disorder patients.
2012
Alterations in the structure and physiology of the prefrontal cortex (PFC) have been found in different psychiatric disorders and some of them involve inhibitory networks, especially in schizophrenia and major depression. Changes in the structure of these networks may be mediated by the polysialylated neural cell adhesion molecule (PSA-NCAM), a molecule related to neuronal structural plasticity, expressed in the PFC exclusively by interneurons. Different studies have found that PSA-NCAM expression in the hippocampus and the amygdala is altered in schizophrenia, major depression and animal models of these disorders, in parallel to changes in the expression of molecules related to inhibitory …
Development and implementation of guidelines for the management of depression: a systematic review
2020
To evaluate the development and implementation of clinical practice guidelines for the management of depression globally.We conducted a systematic review of existing guidelines for the management of depression in adults with major depressive or bipolar disorder. For each identified guideline, we assessed compliance with measures of guideline development quality (such as transparency in guideline development processes and funding, multidisciplinary author group composition, systematic review of comparative efficacy research) and implementation (such as quality indicators). We compared guidelines from low- and middle-income countries with those from high-income countries.We identified 82 nati…
Laparoscopic Management of External Iliac Artery Injury Using Yasargil Clamps and Intracorporeal Suture
2011
Presented is a case report of laparoscopic repair of an external iliac artery injury using titanium Yasargil clamps and intracorporeal suture during lymphadenectomy. Yasargil clamps were introduced and placed, 1 distal and 1 proximal to the lesion. The vascular injury site was identified and repaired using intracorporeal sutures. Laparoscopic staging was completed successfully. No sign of thrombosis or vascular occlusion was detected. The patient was discharged on postoperative day 4 to receive adjuvant therapy. Laparotomy is the accepted way of managing major vascular injuries during laparoscopy. However, in controlled circumstances, with availability of Yasargil clamps and a surgeon exper…
Group Therapy Module to Enhance Self-Esteem in Patients with Borderline Personality Disorder: A Pilot Study
2010
Psychotherapeutic treatments of borderline personality disorder (BPD) often focus on severe behavioral problems. Until now, few techniques have been developed to specifically address low self-esteem in BPD. We developed a 6-session psychoeducative group therapy module to treat low self-esteem in BPD patients. After developing and piloting the therapy module, a controlled outpatient pilot study was performed. Nineteen female BPD patients participated in the group module after discharge from an inpatient DBT program. Twenty-four female BPD patients served as controls. Outcome was assessed by different self-esteem measures. Results showed a greater improvement in self-esteem in the interventio…
Up-Regulation of leucocytes Genes Implicated in Telomere Dysfunction and Cellular Senescence Correlates with Depression and Anxiety Severity Scores
2012
BACKGROUND: Major depressive disorder (MDD) is frequently associated with chronic medical illness responsible of increased disability and mortality. Inflammation and oxidative stress are considered to be the major mediators of the allostatic load, and has been shown to correlate with telomere erosion in the leucocytes of MDD patients, leading to the model of accelerated aging. However, the significance of telomere length as an exclusive biomarker of aging has been questioned on both methodological and biological grounds. Furthermore, telomeres significantly shorten only in patients with long lasting MDD. Sensitive and dynamic functional biomarkers of aging would be clinically useful to eval…
Impacts of ambient temperature and clutch size on incubation behaviour onset in a female-only incubator songbird
2021
Ambient temperature is assumed to be the major cue used by passerines to synchronize their laying and hatching dates to the expected peak of prey availability. While laying eggs, females are still able to fine-tune their hatching date following increasing or decreasing patterns of ambient temperature, mostly via changes in incubation onse t. The onset of incubation behaviour in relation to the laying sequence could have later conse- quences for the duration of the incubation period and the extent of hatching asynchrony. Clutch size is also known to affect incubation patterns and might therefore condition potential responses to changing temperatures. In this study we assessed the association…
Variation in Great Tit Nest Mass and Composition and Its Breeding Consequences: A Comparative Study in four Mediterranean Habitats
2013
Bird nests are structures whose properties affect breeding performance. Thus, the vast majority of bird species build their own characteristic nests, selecting appropriate materials to do so. However, in habitats where the availability of "ideal" materials is low, some ability to use alternative ones would be necessary, even at the cost of having breeding success reduced. The Great Tit (Parus major) breeds under widely different environmental conditions. Its nests are althought to be composed mainly of moss, although very few studies have quantified nest composition. Our target here was describing Great Tit nest mass and composition in four different Mediterranean habitats, and exploring th…
