Objectives: To describe and compare the initial clinical characteristics of a cohort of patients with suspected COVID-19 managed by general practitioners (GPs); to assess whether 3-month persistent symptoms were more frequent among confirmed cases than among no-COVID cases; and to identify factors predictive of persistent symptoms and adverse outcomes among confirmed cases.
Design And Setting: A comparative, prospective, multicentre cohort study in primary care in the Paris region of France.
Participants: 521 patients aged ≥18 with suspected COVID-19 were enrolled between March and May 2020.
Outcome Measures: Initial symptoms, COVID-19 status, persistent symptoms 3 months after inclusion and a composite criterion for potentially COVID-19-related events (hospitalisation, death, emergency department visits). The final COVID-19 status ('confirmed', 'no-COVID' and 'uncertain' cases) was determined by the GP after the receipt of the laboratory test results.
Results: 516 patients were analysed; 166 (32.2%) were classified into the 'confirmed COVID' group, 180 (34.9%) into the 'no-COVID' group and 170 (32.9%) in the 'uncertain COVID' group. Confirmed cases were more likely to have persistent symptoms than no-COVID cases (p=0.09); initial fever/feeling feverish and anosmia were independently associated with persistent symptoms. At 3 months, we observed 16 (9.8%) COVID-19-related hospital admissions, 3 (1.8%) intensive care unit admissions, 13 (37.1%) referrals to an emergency department and no death. Age >70 and/or at least one comorbidity (OR 6.53; 95% CI 1.13-37.84; p=0.036), abnormalities in a lung examination (15.39; 95% CI 1.61-146.77; p=0.057) and two or more systemic symptoms (38.61; 95% CI 2.30-647.40; p=0.011) were associated with the composite criterion.
Conclusions: Although most patients with COVID-19 in primary care had mild disease with a benign course, almost one in six had persistent symptoms at 3 months. These symptoms were more frequent in the 'confirmed COVID' group. Our findings need to be confirmed in a prospective study with longer follow-up.

Sexual and reproductive health is an essential part of comprehensive medical care. As the field of medicine becomes more specialized and siloed and the diagnostic work-up in surgery more advanced, the risk of anchoring diagnoses and partitioning of care increases. Thus, the fundamentals of a complete patient history and review of each body system remain critical in ensuring that surgeons establish a broad differential diagnosis; provide comprehensive, well-rounded care to patients; and create opportunities for patient counseling and interventions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus are primarily transmitted through droplets or aerosols from patients. The inactivation effects of existing virus control techniques may vary depending on the environmental factors. Therefore, it is important to establish a suitable evaluation system for assessing virus control techniques against airborne viruses for further real-world implementation.

Auditory verbal hallucinations (AVHs) in schizophrenia are hypothesized to involve alterations in hemispheric lateralization, but the specific neural mechanisms remain unclear. This study investigated functional intra- and inter-hemispheric connectivity to identify lateralization patterns unique to AVHs. Resting-state fMRI data were collected from 60 schizophrenia patients with persistent AVHs (p-AVH group), 39 patients without AVHs (n-AVH group), and 59 healthy controls (HC group).

Background: Women's elevated risk of Alzheimer's disease (AD) compared to men remains unclear, with gonadal hormones proposed as potential contributors. This study aimed to explore the association between follicle-stimulating hormone (FSH), estradiol (E2), neuropsychological AD stages, and cerebral Aβ deposition.
Methods: A total of 679 subjects were included in the study (N = 198 for cognitively normal (CN), N = 373 for mild cognitive impairment (MCI), and N = 108 for AD dementia groups).

Background: Current treatments for Alzheimer's disease (AD) lack disease-modifying interventions. Hence, novel therapies capable of restraining AD progression and maintaining better brain function for extended periods after the initial diagnosis have great significance. Extracellular vesicles (EVs) from human induced pluripotent stem cell (hiPSC)-derived neural stem cells (NSCs) are attractive in this context due to their robust antiinflammatory properties.
