Background And Aims: The relationship between negative symptoms and cognition in schizophrenia is not clear, inconsistent findings have been reported by multiple authors and meta analyses. The aim of this study was to investigate the relationship between cognition and primary negative symptoms.
Methods: 67 outpatients diagnosed with schizophrenia were evaluated using PANSS and the NSA-16 scale. Correlation and regression analyses were used in the present study to investigate the relationship between the primary negative symptoms and cognition.
Results: No relationship was found between the PANSS Cognitive factor and Negative factor, but when investigating the relationship of the Cognitive PANSS factor with the negative symptoms evaluated with the NSA-16 scale, it was shown that there is a significant association between cognition and motor retardation.
Conclusions: Our study reveals the relative independence of cognitive factor from the global negative domain of the psychopathology, even though the association with motor retardation was clear. These findings also support the need of using appropriate assessment tools in order to gain a more refined understanding of the phenomenology of schizophrenia.

Background: Tuberculosis (TB) remains a leading cause of mortality in low-resource settings and poses a diagnostic challenge in human immunodeficiency virus (HIV)-negative populations because of limitations in traditional diagnostic methods such as sputum smear microscopy (SSM) and sputum Xpert Ultra. There is a lack of effective, non-invasive diagnostic options for TB diagnosis in HIV-negative populations. This scoping review explores the potential of urinary lipoarabinomannan (ULAM) as a point-of-care diagnostic tool for Mycobacterium tuberculosis (MTB) in HIV-negative individuals.

Objectives: Physical function in RA is largely influenced by multiple clinical factors, however, there is a growing body of evidence that psychological state and other comorbidities also play an essential role. Using data obtained in the COVID-19 Vaccination in Autoimmune Diseases study, an international self-reported e-survey, we aimed to explore the predictive ability of sociodemographic and clinical variables on Patient-Reported Outcomes Measurement Information System Physical Function Short Form 10a (PROMIS PF-10a) in RA and to investigate variation in disease activity and functional outcomes based on country-level socio-economic parameters.
Methods: Patient demographics, disease characteristics including current symptom status, functional status and treatment variables, as well as income level of the country of residence, were extracted from survey responses.

Introduction: The prognostic impact of human leukocyte antigen-E (HLA-E) expression and the proportion of natural killer (NK) cells in esophageal squamous cell carcinoma (ESCC) was investigated.
Methods: This study retrospectively evaluated 397 ESCC patients across two centers. The cumulative incidence of recurrence (CIR) and the incidence of tumor-related death (CID) were analyzed in various groups.
