Background: Transgender and gender diverse (TGD) adolescents often experience higher rates of psychiatric co-morbidities, autism spectrum disorder (ASD), and autistic traits. A few studies have described TGD adolescents who were referred to psychiatric clinics. To the best of our knowledge, no study has yet compared clinical characteristics of autistic vs. nonautistic TGD adolescents.

Objectives: To describe the demographic and clinical characteristics of TGD adolescents referred to a tertiary child and adolescent psychiatric clinic, and to compare the characteristics of autistic and nonautistic TGD adolescents.

Methods: We conducted a retrospective study of 28 TDG adolescents who were consecutively referred for psychiatric evaluation in a child and adolescent psychiatric clinic at a tertiary children's hospital between December 2020 and February 2023. Data were collected from electronic medical files.

Results: Of the sample, 67.9% first questioned their gender identity after the onset of secondary sex characteristics (pubertal onset) and 35.7% were identified as gifted. The gifted group had a higher rate of pubertal onset compared to the nongifted group. Our cohort exhibited a higher rate of ASD (39.3%) than the general population. Autistic compared to nonautistic TGD adolescents had a higher rate of giftedness and a lower rate of social transition.

Conclusions: TGD adolescents referred for psychiatric evaluation display distinct features, including high rates of ASD, giftedness, and pubertal onset. Autistic compared to nonautistic TGD are more likely to be gifted and less likely to have undergone social transition.

Background: Recent data regarding polymicrobial bacteremia (PMB) are lacking.

Objectives: To characterize risk factors as well as clinical, microbiological, and prognostic patterns of patients with PMB in a modern hospital setting.

Methods: A single center retrospective study including all patients diagnosed with PMB during 2013 was conducted. PMB was defined as two or more organisms cultured from the blood of the same patient within 72 hours. Patients with monomicrobial infections served as controls.

Results: There were 135 episodes (2% of all bacteremia episodes) of true PMB among 123 patients during the study period. Recent invasive procedures (odds ratio [OR] 3.59, 95% confidence interval [95%CI] 1.41–9.12, P = 0.006) and foreign bodies (OR 1.88, 95%CI 1.06–3.33, P = 0.04) were risk factors for PMB when compared with 79 patients with monomicrobial bacteremia. Central-line-associated infections were the most common infection source among patients with PMB (n=34, 28%). Enterobacteriaceae were the most commonly implicated pathogen (n=95, 77%). Non-fermenting Gram-negative bacilli were significantly more common than previously reported (n=55, 45%). Although crude 30-day mortality was higher (48% vs. 33%) in PMB patients, adjusted mortality was comparable in the two groups.

Conclusions: PMB rate in our cohort was considerably lower than in previous reports. Central-line-associated infections were more common than classic PMB sources. Mortality remained high. Strategies for early identification and better care for these patients should be pursued.
