Background: Memory complaints are frequent in older adults and are associated with higher risk of cognitive decline.
Objective: To investigate the functional outcome of individuals with memory complaints followed up at primary care centers.
Methods: Data were collected between 2016 e 2020 in primary health care centers in Brazil. Patients underwent the Brief Cognitive Screening Battery, and the Functional Activities Questionnaire.
Results: The initial sample (2016) comprised 91 individuals classified into those with subjective cognitive decline (SCD, = 15), mild cognitive impairment (MCI, = 45), or dementia ( = 31). During follow-up, 8 individuals (8.8% of the initial sample) died and 26 (28.5% of the initial sample) were not found. Fifty-seven participants underwent clinical reassessment. Of 15 individuals with SCD, 7 were not found (46.7%), 4 (26.7%) progressed to MCI, and 4 (26.7%) remained stable. Of 45 individuals with MCI, 11 were not found (24.4%), 2 (4.4%) died, 6 (13.4%) progressed to dementia, 12 (26.7%) regressed to SCD, and 14 (31.1%) remained stable. Of 31 individuals with dementia, 8 were not found (25.8%), 6 (19.4%) died, 2 (6.5%) regressed to SCD, 7 (22.6%) regressed to MCI, and 8 remained stable (25.8%). Clinical improvement was due to the treatment of reversible causes, such as B12 hypovitaminosis and mood disorders. Older age, lower Mini-Mental State Examination, and higher scores of memory complaint, but not the use of benzodiazepines and of proton pump inhibitors, were predictors of functional status.
Conclusion: Despite their limits (short sample size, missing data), these results support the idea that adequate screening, follow-up, and treatment of reversible causes of dementia in primary care are essential.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade fibrohistiocytic tumor with malignant potential. It is considered to have a high local recurrence rate due to the characteristic invasion of the finger-like lesion into the soft tissues.
Method: This retrospective study presents details of 20 DFSP patients with a history of surgery and a long follow-up period.
Symptom Attributions in Illness Anxiety Disorder.

Objectives: A major characteristic of health anxiety is the tendency to attribute benign bodily sensations to serious illnesses. This has been supported by empirical research in non-clinical samples, and samples of individuals diagnosed with Hypochondriasis. However, no study to date has explored symptom attribution styles of individuals with the DSM-5 diagnosis of Illness Anxiety Disorder.

Background: Major depressive disorder (MDD) is characterized by persistent feelings of sadness and loss of interest. Ketamine has been widely used to treat MDD owing to its rapid effect in relieving depressive symptoms. Importantly, not all patients respond to ketamine treatment.

X-ray spectroscopies are uniquely poised to describe the geometric and electronic structure of metalloenzyme active sites under a wide variety of sample conditions. UV/Vis (ultraviolet/visible) spectroscopy is a similarly well-established technique that can identify and quantify catalytic intermediates. The work described here reports the first simultaneous collection of full in situ UV/Vis and high-energy resolution fluorescence detected x-ray absorption spectra.

During the preparation of single-domain (S-D) REBaCuO (RE-123) superconducting bulks, the seed crystals can serve as templates for crystal growth, guiding the newly formed crystals to grow in a specific direction, thereby ensuring the consistency of the crystal orientation within the sample. However, the infiltration temperature is typically restricted to approximately 1050 °C when employing NdBaCuO (Nd-123) crystal seeds in the traditional top-seeded infiltration growth (TSIG) technique for producing single-domain Y-123 bulk superconductors. In the present study, to overcome the temperature limitations of the heat treatment process, the optimized YO +011 IG (011 refers to BaCuO powder) method was employed to fabricate a group of single-domain Y-123 bulks with a high-temperature infiltration (1000-1300 °C).
