Clinical utility of F-18-FDG PET/CT in the follow-up of a large cohort of patients with high-risk differentiated thyroid carcinoma

Objective: To evaluate the clinical utility of F-18-FDG PET/CT in patients with high-risk DTC. Subjects and methods: Single-center retrospective study with 74 patients with high-risk differentiated thyroid cancer (DTC), classified in 4 groups. Group 1: patients with positive sTg or TgAb, subdivided in Group 1A: negative RxWBS and no foci of metastases identified at conventional image (n = 9)Group 1B: RxWBS not compatible with suspicious foci at conventional image or not proportional to sTg level (n = 13)Group 2: patients with histological findings of aggressive DTC variants (n = 21) and Group 3: patients with positive RxWBS (n = 31). Results: F-18-FDG PET/CT identified undifferentiated lesions and helped restage the disease in groups 1B and 2. The scan helped guide clinical judgment in 9/13 (69%) patients of group 1B, 10/21 (48%) patients of group 2 and 2/31 (6%) patients of group 3. There was no clinical benefit associated with group 1A. F-18-FDG PET/CT was associated with progressive disease. Conclusion: F-18-FDG PET/CT is a useful tool in the follow-up of patients with high-risk DTC, mainly in the group of RxWBS not compatible with suspicious foci at conventional image or not proportional to sTg level and in those with aggressive DTC variants. Additionally, this study showed that F-18-FDG PET/CT was associated with progression and helped display undifferentiated lesions guiding clinical assessments regarding surgeries or expectant treatments.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Ministério da Saúde (MS)Univ Fed São Paulo EPM Unifesp, Escola Paulista Med, Ctr Doencas Tireoide, São Paulo, SP, BrazilUniv Fed São Paulo EPM Unifesp, Escola Paulista Med, Lab Endocrinol Mol & Translac, Dept Med,Div Endocrinol, São Paulo, SP, BrazilHIAE, Dept Imagem, São Paulo, SP, BrazilUniv Fed São Paulo EPM Unifesp, Escola Paulista Med, Ctr Doencas Tireoide, São Paulo, SP, BrazilUniv Fed São Paulo EPM Unifesp, Escola Paulista Med, Lab Endocrinol Mol & Translac, Dept Med,Div Endocrinol, São Paulo, SP, BrazilFAPESP: 2006/60402-1MS: 25000.168513/2008-11Web of Scienc

Fatal Ceftriaxone-induced hemolysis in a child with congenital cytomegalovirus infection

A 7-year-old girl with congenital Cytomegalovirus infection had a massive, fatal intravascular hemolysis after intravenous administration of ceftriaxone. Laboratory studies confirmed the presence of antibodies against ceftriaxone in the serum and on the patient's red blood cells. No evidence of sepsis or anaphylaxis was found

Genome sequence of <em>Coxiella burnetii</em> strain Namibia.

We present the whole genome sequence and annotation of the Coxiella burnetii strain Namibia. This strain was isolated from an aborting goat in 1991 in Windhoek, Namibia. The plasmid type QpRS was confirmed in our work. Further genomic typing placed the strain into a unique genomic group. The genome sequence is 2,101,438&nbsp;bp long and contains 1,979 protein-coding and 51 RNA genes, including one rRNA operon. To overcome the poor yield from cell culture systems, an additional DNA enrichment with whole genome amplification (WGA) methods was applied. We describe a bioinformatics pipeline for improved genome assembly including several filters with a special focus on WGA characteristics

Evaluation of the capacity to consent to treatment among patients with bipolar disorder: Comparison between the acute psychopathological episode and the stable mood phase

Objective: Treatment decision-making capacity (TDMC) is basic to therapeutic processes and can be measured with the MacArthur Competence Assessment Tool for Treatment (MacCAT-T). TDMC may fluctuate in bipolar disorder (BD). We used the MacCAT-T to compare BD inpatients with an acute manic or depressive episode with euthymic BD outpatients on their TDMC. Methods: We used the MacCAT-T to cross-sectionally assessed from May 2018 through October 2019 the TDCM of adult BD patients with a Mini Mental State Examination score ≥18, a group of acutely ill hospitalized patients for a manic/hypomanic episode and another of euthymic outpatients during their regular visits at our outpatient clinic. Patients were assessed with other specific psychiatric rating scales. We also tested their TDCM to an alternative treatment. Results: The inpatient group consisted of 53 patients and the outpatient of 47. Inpatients scored worse than outpatients on the MacCAT-T understanding, reasoning and expressing a choice subscale, but not on the appreciating scale. Outpatients were more capable in understanding the characteristics of an alternative advance treatment. MacCAT-T subscales correlated directly with mental state scores, and inversely with mania and psychopathology scores, while only the appreciating subscale correlated inversely with depression scores. Limitations: The limitations include small sample size and cross-sectional design. Conclusions: TDCM is higher in BD patients at their euthymic state, hence this is the right time to obtain consent from a BD patient in view of possibly depositing psychiatric advance directives

First episode psychosis during the Covid-19 pandemic in Milan, Italy: Diagnostic outcomes at 1-year follow-up

An influence of the Covid-19 pandemic on First Episode Psychosis (FEP) has been hypothesized. We previously reported an increase of FEP during the early stages of the pandemic in Milan, Italy. Here we report a 1-year follow-up of the same cohort and comparison with a FEP cohort from 2019. The higher proportion of non-chronic psychoses observed during the pandemic (58.62% in 2020 vs 43,75% in 2019) should be confirmed in larger cohorts over a longer follow-up period

Type 1 diabetes onset in Lombardy region, Italy, during the COVID-19 pandemic: The double-wave occurrence

Background: The Italian Lombardy region has been the epicenter of COVID-19 since February 2020. This study analyses the epidemiology of pediatric type 1 diabetes (T1D) onset during the first two pandemic waves and three previous years. Methods: All the 13 pediatric diabetes centers in Lombardy prospectively evaluated charts of children at T1D onset (0–17 years), during year 2020. After calculating the annual incidence, the data were compared with those of the 3 previous years, using generalized linear models, adjusted for age and sex. Monthly T1D new onsets and diabetic ketoacidosis (DKA) were investigated yearly from 2017 to 2020. Data were extracted from outpatients charts of the pediatric diabetes centers and from the database of the national institute of statistics. Findings: The estimated incidence proportion of T1D was 16/100·000 in 2020, compared to 14, 11 and 12 in 2019, 2018 and 2017, respectively. When adjusting for age and gender, the incidence was significantly lower in 2018 and 2017 compared to 2020 (adjusted incidence ratio: 0.73 and 0.77 respectively, with 95% CI: 0.63 to 0.84, and 0.67 to 0.83; p = 0·002 and p = 0·01), but no difference was found between the years 2020 and 2019. A reduction trend in the percentage of T1D diagnosis during the first wave (March-April) over the total year diagnoses was observed compared to previous years (11·7% in 2020, 17·7% in 2019, 14·1% in 2018 and 14·4% 2017). No difference was observed during the second wave (October-December) (32·8% in 2020, 33·8% in 2019, 34% in 2018, 30·7% in 2017). The proportion of DKA over the total T1D diagnoses during the second wave had higher trend than the first one (41·7% vs 33·3%), while severe DKA over the total DKA appeared higher during the first wave (60% vs 37·1%). Interpretation: The study suggests an increase in the incidence of pediatric T1D in Lombardy throughout the past five years. Pandemic waves may have affected the clinical presentation at onset.
