Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Influence of family carers on haemodialyzed patients' adherence to dietary and fluid restrictions: an observational study
No full textAIM:
To determine the influence of a family carer on haemodialyzed patients''adherence'.
BACKGROUND:
There is extensive evidence showing that successful treatment of patients with end-stage renal disease is directly related to patients''adherence'. The parameters indicative of a good adherence are potassium and phosphate serum levels and the interdialytic weight gain. Haemodialyzed patients may have scarce adherence to food and fluid intake restrictions, and medications schedule.
DESIGN:
Case-control study carried out in a haemodialysis centre in Italy.
DATA SOURCES:
The data were collected during 2010.
METHODS:
A total of 72 subjects with end-stage renal disease participated in the study. The subjects assisted by a family carer were identified as cases (n = 36), whereas those who did not have a family carer, as controls (n = 36). All subjects were followed up (4 months) and checked up regarding interdialytic weight gain, and serum levels of potassium and phosphate. Important differences in potassium and phosphate serum level and interdialytic weight gain between the two groups were evaluated separately using a repeated measures anova test.
RESULTS:
Participants in the case group showed significantly lower phosphate and potassium serum levels and a lower interdialytic weight gain during follow-up when compared to controls.
CONCLUSIONS:
The presence of a family carer improves patients' adherence, particularly as far as phosphate levels are concerned, since phosphate intake plays a fundamental role in avoiding long-term complications in end-stage renal disease patients
Who’s the leader, mania or depression? Predominant polarity and alcohol/polysubstance use in bipolar disorders
Full text linkBackground: Predominant polarity characterises patients who mainly manifest recurrences of depression or mania/hypomania. Alcohol use disorder (AUD) and polysubstance use (PSU), which often complicate bipolar disorder (BD) and affect its clinical course, can influence predominant polarity. Nevertheless, previous studies have not clarified if BD patients differ in predominant polarity from BD patients with substance use disorder (SUD) comorbidity. Objective: The aim of this study was to compare predominant polarity between BD without SUD, BD with AUD and BD with PSU. We also investigated the association between predominant polarity and first episode polarity in each diagnostic group. Method: We evaluated predominant polarity (≥2:1 lifetime depressive vs. manic/hypomanic episodes) in 218 DSM-IV-TR BD patients. Specifically, data were obtained from 86 patients with BD without SUD, 69 patients with BD and AUD, and 63 patients with BD and PSU with alcohol as the primary substance abused. Results: The three groups significantly differed for predominant polarity. The most common predominant polarity in BD without SUD was manic, while in BD with AUD and in BD with PSU it was depressive. Uncertain predominant polarity was the least common in BD without SUD and BD with PSU, whereas in BD with AUD, manic predominant polarity was least common. Predominant polarity matched onset polarity in all groups. Conclusion: BD without SUD, BD with AUD, and BD with PSU have different predominant polarities. The correspondence between predominant polarity and polarity at onset may impact diagnosis and treatment of BD
