Berechnung des Pflichtbeitrags eines niedergelassenen Arztes zum ?rztlichen Versorgungswerk bei Insolvenz

1. Wird dem Insolvenzsschuldner von den Gl?ubigern die Fortführung seiner Arztpraxis gestattet (sog. Betriebsfortführung), stellen die Pflichtbeitr?ge zur Altersversorgung sonstige Massenverbindlichkeiten dar, die gem. § 53 InsO vorweg durch den Insolvenzverwalter zu berichtigen sind. 2. Der Umstand, dass die Gl?ubigerversammlung im Rahmen der Betriebsfortführung für den fortführenden Arzt einen bestimmten monatlichen Unterhalt festgesetzt hat, bedingt keine Umqualifizierung der T?tigkeit als niedergelassener Arzt in eine Angestelltent?tigkeit. Die Pflichtbeitr?ge zur Altersversorgung sind daher nach den für Niedergelassene geltenden Satzungsbestimmungen zu berechnen, so dass nach wie vor allein der in der Praxis erzielte Gesamtumsatz und nicht der dem Arzt gew?hrte Unterhaltsbetrag als Berechnungsgrundlage für den Beitragssatz heranzuziehen ist.     

The J-curve relationship of treated diastolic blood pressure to mortality risk: Is it real? Is it clinically meaningful?

Low diastolic blood pressure is alleged to impose excess cardiovascular disease (CVD) risk in patients with treated hypertension, impeding aggressive reduction of blood pressure. Most investigations that assessed the potential J-shaped relations of diastolic blood pressure and adverse outcomes have not adequately considered systolic or pulse pressure in statistical analyses. An overview of hypertension trials indicates that lowering elevated blood pressure reduces the risk of CVD outcomes irrespective of the associated decrease in diastolic pressure, even if the achieved diastolic pressure averages less than 70 mm Hg. The Framingham study investigations have determined that the increased CVD incidence observed at low diastolic blood pressure levels is confined largely to persons with concomitantly increased systolic pressure. This finding of no true excess risk at low diastolic blood pressure agrees with the results of trials that have evaluated the J-curve phenomenon adjusting for systolic pressure. Aggressively treating systolic hypertension appears to produce no cause for alarm.     

Evaluation of four elastomeric interocclusal recording materials

Background: The fabrication of dental prosthesis requires the transfer of interocclusal records from patient's mouth to semiadjustable articulators using different kinds of recording media. Any inaccuracy in these interocclusal records leads to occlusal errors in the final prosthesis. This study was conducted to evaluate the dimensional changes occurring in the interocclusal recording material over a given period of time and the material's resistance to compression during the cast mounting on the articulator.     

Failure to detect an antimutator phenotype following disruption of the Saccharomyces cerevisiae DDR48 gene

The antimutator phenotype, reportedly conferred by disruption of the Saccharomyces cerevisiae DDR48 gene, was suggested to affect only a specific spontaneous mutational pathway. We attempted to identify the types of mutation that are DDR48-dependent by determining the specificity of the ddr48 antimutator. However, disruption of DDR48 did not decrease the rates of spontaneous forward mutation in a plasmid-borne copy of the yeast SUP4-o gene, the reversion or suppression of the lys2–1 allele, or forward mutation at the CAN1 locus. Interestingly, the latter gene had been reported previously to be subject to the antimutator effect. DNA sequence analysis of spontaneous SUP4-o mutations arising in DDR48 and ddr48 backgrounds provided no evidence for a reduction in the rates of individual mutational classes. Thus, we were unable to verify that disruption of DDR48 causes an antimutator phenotype.     

Maternal Nutrition—Effect on Fetal Growth and Outcome of Pregnancy

During the first half of the 20th century, chronic energy undernutrition due to low dietary intake, repeated infections, and rapid succession of pregnancy were the factors most responsible for maternal undernutrition and consequent adverse outcomes of pregnancy. Efforts to improve dietary intake, treatment of infections, and provision of contraceptive care were the major focuses of intervention from 1950 to 1990. These interventions resulted in reduction in severe grades of undernutrition. However, there was no reduction in mild and moderate degrees of undernutrition and anemia during pregnancy and there was no significant improvement in the course and outcome of pregnancy, or in birth weight. During the 1990s, among the middle- and upper-income groups, there has been a progressive rise in obesity and consequent adverse effects. The advent of HIV infection in India in the 1980s will inevitably lead to increases in severe undernutrition associated with HIV infection in pregnancy and an adverse impact of maternal HIV infection on the fetus. Practicing physicians and nutritionists in the new millennium will therefore have to assess each person individually and provide appropriate advice regarding diet, exercise, fertility, and infection prevention and control in order to achieve optimum health and nutrition status during pregnancy and to prevent adverse pregnancy outcomes.     

Bipolar affective disorder. II. EEG, neuropsychological, and clinical correlates of CT abnormality

Since the clinical significance of CT abnormalities found in bipolar patients remains obscure, we studied 26 DSM-III bipolar patients who had specific CT abnormalities (third ventricle enlargement, and hyperdensity of the caudate, thalamus, anterior frontal white matter, and right temporal lobe) on numerous parameters such as EEG, the Halstead-Reitan Neuropsychological Battery, premorbid personality adjustment, family history of affective disorder, positive and negative symptoms, employment history, and response to lithium carbonate treatment. None of these measures could differentiate between the CT abnormal and CT normal subgroups. The implications of these findings are discussed.
