Incidence of seropositive rheumatoid arthritis in population-based studies in Northern Savo, Finland, during 1980-2020.

The objective is to evaluate the incidence of seropositive rheumatoid arthritis (RA) over 40-year period in Northern Savo, Finland. Data on new seropositive RA patients according to the American College of Rheumatology (ACR) 1987 classification criteria were collected in 2020-2021. In 2020 data on tobacco exposure, patient-reported dental health and living in residences with fluoridated tap water were gathered.

Transferrin receptor expression on reticulocytes as a marker of iron status in dialyzed patients.

Background: Erythropoietin therapy should be accompanied by an adequate iron supply in order to avoid functional iron deficiency (FID) related to enhanced erythropoiesis. Therefore, accurate monitoring of the body's iron homeostasis is needed. This study was conducted to investigate whether transferrin receptor (TfR) expression on reticulocytes can reflect iron status in patients with chronic renal failure (CRF).

The effectiveness of a scalp cooling cap in preventing chemotherapy-induced alopecia.

Aims And Background: Hair loss is one of the most unpleasant side effects associated with chemotherapy treatments. It causes emotional disturbances and constantly reminds the patient of the disease. This study analyzed the effectiveness of scalp cooling caps in preventing alopecia among 64 patients.

Muscle symptoms associated with statins: a series of twenty patients.

The aim of this study was to examine the clinical profile of statin-induced myalgia in patients with no apparent predisposing factors. Patients who reported muscle complaints that limited daily functioning during statin use were prospectively identified among the patients of Kuusankoski District Hospital and its catchment area, a population of about 100,000, between January 2003 and July 2004. Twenty patients in whom the muscle complaints were probably attributable to the use of a statin were included in this series.

Central auditory processing of durational changes in complex speech patterns by newborns: an event-related brain potential study.

In this study, newborns' ability to discriminate durational changes in the fricative /s/ within a nonsense word was investigated. The results showed that infrequent increments and decrements of a speech sound duration elicit a mismatch negativity kind of response in sleeping human newborns. In the auditory event-related potential to these deviant stimuli two negative waves of this response were revealed.
