The phenomenological experiences of Autobiographical Memory: A cross-sectional and a longitudinal study

Phenomenology is a critical component of autobiographical memory retrieval. Some memories are vivid and rich in sensory details whereas others are faded; some memories are experienced as emotionally intense whereas others are not. Sutin and Robins (2007) identified 10 dimensions in which a memory may vary—i.e., Vividness, Coherence, Accessibility, Sensory Details, Emotional Intensity, Visual Perspective, Time Perspective, Sharing, Distancing, and Valence—and developed a comprehensive psychometrically sound measure of memory phenomenology, the Memory Experiences Questionnaire (MEQ). Phenomenology has been linked to underlining stable dispositions—i.e. personality, as well as to a variety of positive/negative psychological outcomes—well-being and life satisfaction, depression and anxiety, among others. Using the MEQ, a cross-sectional and a longitudinal study were conducted on a large sample of American and Italian adults. In both studies, participants retrieved two ‘key’ personal memories, a Turning Point and a Childhood Memory, and rated the affect and phenomenology of each memory. Participants also completed self-reported measures of personality (i.e. Neuroticism and Conscientiousness), and measures of depression, well-being and life satisfaction. The present research showed that phenomenological ratings tend (a) to cross-sectionally increase across adulthood (Study 1), and (b) to be moderately stable over time, regardless the contents of the memories (Study 2). Interrelations among memory phenomenology, personality and psychological outcome variables were also examined (Study 1 and Study 2). In particular, autobiographical memory phenomenology was proposed as a dynamic expression of personality functioning that partially explains adaptive/maladaptive psychological outcomes. In fact, the findings partially supported the hypothesized mediating effect of phenomenology on the personality association with psychological outcomes. Implications of the findings are discussed proposing future lines of research. In particular, the need for more longitudinal studies is highlighted, along with the combined application of both self-report questionnaires and narrative measures.

Valutazione del rapporto urinario proteine totali/creatinina e albumina/creatinina in cani affetti da iperadrenocorticismo e da diabete mellito

INTRODUCTION – In human medicine, diabetes mellitus (DM), hypertension, proteinuria and nephropathy are often associated although it is still not clear whether hypertension is the consequence or the cause of nephropathy and albuminuria. Microalbuminuria, in humans, is an early and sensitive marker which permits timely and effective therapy in the early phase of renal damage. Conversely, in dogs, these relationships were not fully investigated, even though hypertension has been associated with many diseases (Bodey and Michell, 1996). In a previous study, 20% of diabetic dogs were found proteinuric based on a U:P/C > 1 and 46% were hypertensive; this latter finding is similar to the prevalence of hypertension in diabetic people (40-80%) (Struble et al., 1998). In the same canine study, hypertension was also positively correlated with the duration of the disease, as is the case in human beings. Hypertension was also found to be a common complication of hypercortisolism (HC) in dogs, with a prevalence which varies from 50 (Goy-Thollot et al., 2002) to 80% (Danese and Aron, 1994).The aim of our study was to evaluate the urinary albumin to creatinine ratio (U:A/C) in dogs affected by Diabetes Mellitus and HC in order to ascertain if, as in human beings, it could represent an early and more sensitive marker of renal damage than U:P/C. Furthermore, the relationship between proteinuria and hypertension in DM and HC was also investigated. MATERIALS AND METHODS – Twenty dogs with DM, 14 with HC and 21 healthy dogs (control group) were included in the prospective case-control study. Inclusion criteria were hyperglycaemia, glicosuria and serum fructosamine above the reference range for DM dogs and a positive ACTH stimulation test and/or low-dose dexamethasone test and consistent findings of HC on abdominal ultrasonography in HC dogs. Dogs were excluded if affected by urinary tract infections and if the serum creatinine or urea values were above the reference range. At the moment of inclusion, an appropriate therapy had already been instituted less than 1 month earlier in 12 diabetic dogs. The control dogs were considered healthy based on clinical exam and clinicopathological findings. All dogs underwent urine sample collection by cystocentesis and systemic blood pressure measurement by means of either an oscillometric device (BP-88 Next, Colin Corporation, Japan) or by Doppler ultrasonic traducer (Minidop ES-100VX, Hadeco, Japan). The choice of method depended on the dog’s body weight: Doppler ultrasonography was employed in dogs < 20 kg of body weight and the oscillometric method in the other subjects. Dogs were considered hypertensive whenever systemic blood pressure was found ≥ 160 mmHg. The urine was assayed for U:P/C and U:A/C (Gentilini et al., 2005). The data between groups were compared using the Mann-Whitney U test. The reference ranges for U:P/C and U:A/C had already been established by our laboratory as 0.6 and 0.05, respectively. U:P/C and U:A/C findings were correlated to systemic blood pressure and Spearman R correlation coefficients were calculated. In all cases, p < 0.05 was considered statistically significant. RESULTS – The mean ± sd urinary albumin concentration in the three groups was 1.79 mg/dl ± 2.18; 20.02 mg/dl ± 43.25; 52.02 mg/dl ± 98.27, in healthy, diabetic and hypercortisolemic dogs, respectively. The urine albumin concentration differed significantly between healthy and diabetic dogs (p = 0.008) and between healthy and HC dogs (p = 0.011). U:A/C values ranged from 0.00 to 0.34 (mean ± sd 0.02 ± 0.07), 0.00 to 6.72 (mean ± sd 0.62 ± 1.52) and 0.00 to 5.52 (mean ± sd 1.27 ± 1.70) in the control, DM and HC groups, respectively; U:P/C values ranged from 0.1 to 0.6 (mean ± sd 0.17 ± 0.15) 0.1 to 6.6 (mean ± sd 0.93 ± 1.15) and 0.2 to 7.1 (mean ± sd 1.90 ± 2.11) in the control, DM and HC groups, respectively. In diabetic dogs, U:A/C was above the reference range in 11 out of 20 dogs (55%). Among these, 5/20 (25%) showed an increase only in the U:A/C ratio while, in 6/20 (30%), both the U:P/C and the U:A/C were abnormal. Among the latter, 4 dogs had already undergone therapy. In subjects affected with HC, U:P/C and U:A/C were both increased in 10/14 (71%) while in 2/14 (14%) only U:A/C was above the reference range. Overall, by comparing U:P/C and U:A/C in the various groups, a significant increase in protein excretion in disease-affected animals compared to healthy dogs was found. Blood pressure (BP) in diabetic subjects ranged from 88 to 203 mmHg (mean ± sd 143 ± 33 mmHg) and 7/20 (35%) dogs were found to be hypertensive. In HC dogs, BP ranged from 116 to 200 mmHg (mean ± sd 167 ± 26 mmHg) and 9/14 (64%) dogs were hypertensive. Blood pressure and proteinuria were not significantly correlated. Furthermore, in the DM group, U:P/C and U:A/C were both increased in 3 hypertensive dogs and 2 normotensive dogs while the only increase of U:A/C was observed in 2 hypertensive and 3 normotensive dogs. In the HC group, the U:P/C and the U:A/C were both increased in 6 hypertensive and 2 normotensive dogs; the U:A/C was the sole increased parameter in 1 hypertensive dog and in 1 dog with normal pressure. DISCUSSION AND CONCLUSION- The findings of this study suggest that, in dogs affected by DM and HC, an increase in U:P/C, U:A/C and systemic hypertension is frequently present. Remarkably, some dogs affected by both DM and HC showed an U:A/C but not U:P/C above the reference range. In diabetic dogs, albuminuria was observed in 25% of the subjects, suggesting the possibility that this parameter could be employed for detecting renal damage at an early phase when common semiquantiative tests and even U:P/C fall inside the reference range. In HC dogs, a higher number of subjects with overt proteinuria was found while only 14% presented an increase only in the U:A/C. This fact, associated with a greater number of hypertensive dogs having HC rather than DM, could suggest a greater influence on renal function by the mechanisms involved in hypertension secondary to hypercortisolemia. Furthermore, it is possible that, in HC dogs, the diagnosis was more delayed than in DM dogs. However, the lack of a statistically significant correlation between hypertension and increased protein excretion as well as the apparently random distribution of proteinuric subjects in normotensive and hypertensive cases, imply that other factors besides hypertension are involved in causing proteinuria. Longitudinal studies are needed to further investigate the relationship between hypertension and proteinuria.

Myotonic syndromes: analysis of factors with pathogenetic and prognostic significance

Background: The natural history of Myotonic Dystrophy type 1 is largely unclear, longitudinal studies are lacking. Objectives: to collect clinical and laboratory data, to evaluate sleep disorders, somatic and autonomic skin fibres, neuropsychological and neuroradiological aspects in DM1 patients. Methods: 72 DM1 patients underwent a standardized clinical and neuroradiological evaluation performed by a multidisciplinary team during 3 years of follow-up. Results: longer disease duration was associated with higher incidence of conduction disorders and lower ejection fraction; higher CVF values were predictors for a reduced risk of cardiopathy. Lower functional pulmonary values were associated with class of expansion and were negatively associated with disease duration; arterial blood gas parameters were not associated with expansion size, disease duration nor with respiratory function test. Excessive daytime sleepiness was not associated with class of expansion nor with any of the clinical parameters examined. We detected apnoea in a large percentage of patients, without differences between the 3 genetic classes; higher CVF values were predictors for a reduced risk of apnoea. Skin biopsies demonstrated the presence of a subclinical small fibre neuropathy with involvement of the somatic fibres. The pupillometry study showed lower pupil size at baseline and a lower constriction response to light. The most affected neuropsychological domains were executive functions, visuoconstructional, attention and visuospatial tasks, with a worse performance of E1 patients in the visuoperceptual ability and social cognition tasks. MRI study demonstrated a decrease in the volumes of frontal, parietal, temporal, occipital cortices, accumbens, putamen nuclei and a more severe volume reduction of the isthmus cingulate, transverse temporal, superior parietal and temporal gyri in E2 patients. Discussion: only some clinical parameters could predict the risk of cardiopathy, pulmonary syndrome and sleep disorders, while other clinical aspects proved to be unpredictable, confirming the importance of periodic clinical follow-up of these patients.

Sleep disorders in Multiple System Atrophy: a longitudinal study

Introduction: A higher frequency of sleep and breathing disorders in Multiple System Atrophy (MSA) populations is documented in literature. The analysis of disease progression and prognosis in patients with sleep and breathing disorders could shed light on specific neuropathology and pathophysiology of MSA. Objective: To characterize sleep disorders and their longitudinal modifications during disease course in MSA patients, and to determine their prognostic value. Methods: This is a retrospective and prospective cohort study including 182 MSA patients (58.8% males). Type of onset was defined by the first reported motor or autonomic symptom/sign related to MSA. The occurrence of symptoms/signs and milestones of disease progression and their latency were collected. REM sleep behaviour disorder (RBD) and stridor were video-polysomnography (VPSG)-confirmed. VPSG recordings were analysed in a standardized fashion during the disease course. Survival data were based on time to death from the first symptom of disease. Results: Isolated RBD represented the first MSA symptom in 30% of patients, preceding disease onset according to international criteria with a median of 3(1–5) years. Patients developing early stridor or presenting with RBD at disease onset showed a more rapid and severe disease progression. These features had independent negative prognostic value for survival. Sleep architecture was characterized by peculiar features which could represent negative markers in MSA prognosis. Patients with stridor treated with tracheostomy showed a reduced risk of death. Conclusions: This is one of the first studies focusing on longitudinal progression of sleep in MSA. Sleep disorders are key features of disease, playing a role in presentation, prognosis and progression. In our MSA cohort, RBD represented the most frequent mode of disease presentation. Moreover, some specific clinical and instrumental sleep features could represent a hallmark of MSA and could be involved in prognosis and, in particular, in sudden death and death during sleep.

Environmental accounting and reporting in Italian local governments: a longitudinal analysis of changes in context, content and process

This research aims at contributing to a better understanding of changes in local governments’ accounting and reporting practices. Particularly, ‘why’, ‘what’ and ‘how’ environmental aspects are included and the significance of changes across time. It adopts an interpretative approach to conduct a longitudinal analysis of case studies. Pettigrew and Whipp’s framework on context, content and process is used as a lens to distinguish changes under each dimension and analyse their interconnections. Data is collected from official documents and triangulated with semi-structured interviews. The legal framework defines as boundaries of the accounting information the territory under local governments’ jurisdiction and their immediate surrounding area. Organisational environmental performance and externalities are excluded from the requirements. An interplay between the local outer context, political commitment and organisational culture justifies the implementation of changes beyond what is regulated and the implementation of transformational changes. Local governments engage in international networks to gain access to funding and implement changes, leading to adopting the dominant environmental agenda. Key stakeholders, like citizens, are not engaged in the accounting and reporting process. Thus, there is no evidence that the environmental aspects addressed and related changes align with stakeholders’ needs and expectations, which jeopardises its significance. Findings from the current research have implications in other EU member states due to the harmonisation of accounting and reporting practices and the common practice across the EU in using external funding to conceptualise and implement changes. This implies that other local governments could also be representing a limited account related to environmental aspects.
