Candidatus Desulforudis audaxviator dominates a 975 m deep groundwater community in central Sweden.

The continental bedrock contains groundwater-bearing fractures that are home to microbial populations that are vital in mediating the Earth's biogeochemical cycles. However, their diversity is poorly understood due to the difficulty of obtaining samples from this environment. Here, a groundwater-bearing fracture at 975 m depth was isolated by employing packers in order to characterize the microbial community via metagenomes combined with prokaryotic and eukaryotic marker genes (16S and 18S ribosomal RNA gene).

Impact of parathyroidectomy for primary hyperparathyroidism on quality of life: A case-control study using Short Form Health Survey 36.

Background: Physical and mental complaints are common in patients with primary hyperparathyroidism (PHPT) and negatively impact quality of life (QOL). Subjective symptoms in current guidelines are not considered an indication for surgery. The purpose of this study was to assess the effect of parathyroidectomy on QOL in patients with PHPT.

Late effects of high-dose adjuvant chemotherapy on white and gray matter in breast cancer survivors: converging results from multimodal magnetic resonance imaging.

The neural substrate underlying cognitive impairments after chemotherapy is largely unknown. Here, we investigated very late (>9 years) effects of adjuvant high-dose chemotherapy on brain white and gray matter in primary breast cancer survivors (n = 17) with multimodal magnetic resonance imaging (MRI). A group of breast cancer survivors who did not receive chemotherapy was scanned for comparison (n = 15).

Self-reported cognitive functioning in postmenopausal breast cancer patients before and during endocrine treatment: findings from the neuropsychological TEAM side-study.

Objective: This study aimed to evaluate self-reported cognitive functioning of postmenopausal breast cancer patients before and during endocrine treatment compared with healthy female controls, and to investigate associations between self-reported cognitive functioning, cognitive test performance and anxiety/depression, fatigue, and menopausal complaints.

Methods: Self-reported cognitive functioning, anxiety/depression, fatigue, menopausal complaints, and cognitive tests performance were assessed before (T1) and after 1 year (T2) of adjuvant endocrine treatment in postmenopausal chemotherapy-naïve breast cancer patients. Self-reported cognitive functioning was assessed by the cognitive failures questionnaire and interview questions concerning cognitive complaints.

Cerebral hyporesponsiveness and cognitive impairment 10 years after chemotherapy for breast cancer.

Chemotherapy is associated with cognitive impairment in a subgroup of breast cancer survivors, but the neural circuitry underlying this side effect is largely unknown. Moreover, long-term impairment has not been studied well. In the present study, functional magnetic resonance imaging (fMRI) and neuropsychological testing were performed in breast cancer survivors almost 10 years after high-dose adjuvant chemotherapy (chemo group, n = 19) and in breast cancer survivors for whom chemotherapy had not been indicated (control group, n = 15).
