Mycobacterium kansasii is the second most common cause of non-tuberculosis mycobacterial diseases in Sao Paulo, Brazil. An important component of the management of infections caused by this organism is antibiotic susceptibility testing. The objective of this study was to determine the drug susceptibility profiles and genotypes of clinical isolates of M. kansasii obtained from patients with or without an infection that met the American Thoracic Society's case definition criteria of M. kansasii disease. One hundred and sixty-nine clinical isolates of M. kansasii collected between 1993 and 1998 in Sao Paulo, Brazil, were tested consecutively. The isolates were genotyped by PCR restriction-enzyme pattern analysis (PRA). Most of the M. kansasii strains were susceptible to isoniazid, streptomycin, rifabutin, rifampicin, clarithromycin, ethionamide, amikacin, clofazimine and cycloserine, and resistant to ethambutol, ciprofloxacin and doxycycline. Of 169 isolates, 167 belonged to the type I PRA genotype and one each belonged to type II and III genotypes. There was no correlation between PRA subtype and M. kansasii disease according to the American Thoracic Society case definition. Clinical trials may be needed to better correlate MIC values with treatment outcomes to identify appropriate parameters for drug-resistance testing of M. kansasii.

A clinical isolate, R131, was isolated from the peritoneal swab of a patient who suffered from ruptured appendicitis with abscess and gangrene in Hong Kong in 2018. Cells are facultatively anaerobic, non-motile, Gram-positive coccobacilli. Colonies were small, grey, semi-translucent, low convex and alpha-haemolytic.

Loneliness, social isolation, and living alone are significant risk factors for mortality, particularly in older adults. This systematic review and meta-analysis aimed to quantify their associations with all-cause and cause-specific mortality in older adults, broadening previous research by including more social factors. Comprehensive searches were conducted in PubMed, APA PsycINFO, and CINAHL until December 31, 2023, following PRISMA 2020 and MOOSE guidelines.

Background: Beyond the use of conventional short-lived PET radionuclides, there is a growing interest in tracking larger biomolecules and exploring radiotheranostic applications. One promising option for imaging medium-sized molecules and peptides is ⁵⁵Co (T₁/₂ = 17.5 h, β⁺ = 76%), which enables imaging of new and already established tracers with blood circulation of several hours.

Complementing the oft-studied construct of isolation, research has increasingly focused on existential isolation (EI), or the subjective feeling of separateness in one's experience. In the clinical realm, several studies have demonstrated that higher EI is associated with more severe mental health problems at a single cross-section of time. Moreover, one study showed that higher pretreatment EI predicted worse psychotherapy outcomes.
