Zusammenfassung

Die vorliegende Studie präsentiert einen Methodenvorschlag für gemeinde- und kreisscharfe Abgrenzungen von Arbeitsmarktregionen auf der Basis von Pendlerverflechtungen. Die Abgrenzung nutzt als Verfahren eine Weiterentwicklung der graphentheoretischen Methode, deren Güte mit dem Modularitätsmaß Q aus der Netzwerkforschung gemessen wird. Die Studie basiert auf Gemeindedaten für Deutschland für die Jahre 1993 bis 2008. Als Ergebnis der Analysen werden gemeinde- und kreisscharfe Abgrenzungen mit 50 Arbeitsmarktregionen vorgestellt. Dieses Abgrenzungsergebnis liefert recht größenheterogene Regionen, besitzt aber über den betrachteten Zeitraum eine hohe zeitliche Stabilität. Es wird dargelegt, dass auch eine kreisscharfe Abgrenzungsvariante ein sehr gutes Ergebnis für die Erfassung von Pendlerverflechtungen und einen hohen Selbstversorgungsgrad der Regionen liefert. Der Vergleich mit bisherigen Abgrenzungen funktionaler Räume in Deutschland anhand verschiedener Merkmale bestätigt die Güte der gefundenen Abgrenzung.

Influence of magnesium sulphate infusion before total thyroidectomy on transient hypocalcemia — a randomised study

Background. Transient hypocalcemia is the most common complication after thyroidectomy. Normomagnesemia is needed for normal secretion of PTH and end-organ responsiveness. Our aim was to determine the influence of infusion of magnesium sulphate before thyroidectomy on the incidence of laboratory and clinical transient hypocalcemia.

Methods. In our prospective study, 48 patients (5 men, 43 women; age 22-73 years, median 45 years), who underwent total or near-total thyroidectomy, were randomised preoperatively. Half of them received intravenously 4 ml of 1M magnesium sulphate at the beginning of the surgical procedure, the other half were the control group. Serum concentrations of calcium, ionised calcium, magnesium, phosphate, albumin and PTH were measured prior to surgery and on the first day after surgery.

Results. Laboratory postoperative hypocalcemia was present in 27% of patients and 23% of patients had clinical signs and/or symptoms of postoperative hypocalcemia. The concentration of total calcium (p=0.024) and of albumin (p=0.01) was lower in the group that received magnesium sulphate.

Conclusions. The patients who received infusion of magnesium sulphate before total thyroidectomy had lower concentration of total serum calcium and albumin in comparison to the control group. There was no statistical difference in the incidence of clinical transient hypocalcemia.

Abstract

Introduction

Most data related to cutaneous melanoma survivors’ health behaviour comes from epidemiological studies and is predominantly concerned with safe-sun behaviour and self-examination. Data regarding other changes of health behaviour are scarce and so are qualitative studies in this realm. The aim of our research is to acquire insight into the experiences of patients with cutaneous melanoma in Slovenia. How did they react to the diagnosis, which changes did they introduce in their health behaviour and how do they assess the role of family doctors?

Methods

Using the qualitative approach of collective case reports, a demographically diverse group of patients with different forms and stages of cutaneous melanoma was selected. Semi-structured interviews conducted by a psychologist were recorded and transcribed verbatim. For data processing, the approach of Qualitative Content Analysis was applied.

Results

We integrated interviewees’ experiences after the diagnosis of cutaneous melanoma in several subcategories: either they did not introduce any changes or they mentioned changing their habits when exposed to the sun and performing skin self-examination; they also emphasized their ways of dealing with stress and raising awareness about melanoma among family members and friends. The role of family doctors in the prevention and care appears unclear; even contradictory.

Conclusion

We obtained insight into the experiences of Slovenian patients with cutaneous melanoma. The interviewees prioritised safe behaviour in the sun, strengthening of psychological stability and raising awareness about melanoma. Findings will be used in the creation of a structured questionnaire for national epidemiological survey.
