Summary: The study included 10 COVID-19 recovered patients with persistent symptoms, showing increased [F-18]FDG uptake in bone marrow and blood vessels. Compared to controls, the recovered patients had higher [F-18]FDG uptake ratios, indicating that SARS-CoV-2 may induce vascular inflammation leading to persisting symptoms.

Summary: The heterogeneous uptake of both F-18 FDG and C-11 methionine on PET/CT in renal cell carcinomas is associated with higher grades of cancer. The metabolic tumour volume on F-18 FDG PET/CT but not C-11 methionine PET/CT is significant in predicting advanced-stage renal cell carcinoma. These metabolic features derived from PET/CT imaging may aid in the development of new drugs targeting glucose and amino acid metabolic pathways.

Summary: Hibernomas are rare benign tumors originating from fetal brown adipose tissue. They can occur in various parts of the body, with thigh, shoulder, back, and neck being the most common locations, and are rarely found in the abdominal cavity, retroperitoneum, breast, bones, scrotum, and perirectum. We present a case of a 58-year-old woman with a mediastinal mass, who was incidentally found to have an FDG-avid fat-containing lesion in the omentum abutting the stomach.

Summary: In this retrospective study of 38 RDD patients, the clinical and [F-18]FDG PET/CT features were characterized. RDD commonly affected the upper respiratory tract, cutaneous/subcutaneous lesions, lymph nodes, bones, central nervous system, and cardiovascular system. In PET/CT, RDD lesions showed FDG avidity, and the SUVmax of the hottest lesion in an individual patient was correlated with C-reactive protein levels and hemoglobin levels. The overall response rate of the first-line treatment was 80.8% for newly diagnosed RDD patients and 72.7% for relapsed/progressive RDD patients.

Summary: A 13-year-old boy was suspected of pericarditis after receiving a second booster dose of bivalent mRNA COVID-19 vaccine. The F-18-FDG PET/CT successfully revealed the simultaneous presence of vaccine-related axillary lymphadenopathy and pericarditis without interference from physiological myocardial uptake, after the patient underwent specific preparation with a carbohydrate-free, high-fat diet.

Summary: This study aimed to improve the statistical power in detecting changes in brain glucose metabolism, amyloid, and tau deposition in Alzheimer's disease studies by using a reference tissue-based quantification approach. The results showed that the tracer-specific reference tissue improved the detection of PET SUVR changes, which is beneficial for early diagnosis, disease progression monitoring, and therapeutic response in Alzheimer's disease.

Summary: This study investigated the value of F-18-FDG PET/MRI in the preoperative assessment of ESCC and compared it with other imaging methods. The results showed that F-18-FDG PET/MRI had higher accuracy and area under the curve in diagnosing primary tumors and regional lymph node metastases. Therefore, F-18-FDG PET/MRI may be a potential supplement or alternative imaging method for preoperative staging of ESCC.

Summary: F-18-FDG PET/MRI is superior to conventional imaging and MRI in nodal staging in patients with newly diagnosed breast cancer. It accurately detects nodal positive status and classifies it into the correct clinical lymph node stage more often. F-18-FDG PET/MRI has the potential to be an alternative to invasive staging procedures for assessing the N stage.

Summary: This study aimed to investigate the feasibility of predicting progression-free survival (PFS) in breast cancer patients using pretreatment F-18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) radiomics signature and clinical parameters. The study found that the integrated clinical-radiomics (ICR) model, which combined clinical parameters and preoperative FDG PET/CT imaging, was able to independently predict PFS in breast cancer patients, and was superior to the clinical model alone and rad-score alone.

Summary: This study conducted a meta-analysis to evaluate the diagnostic and prognostic value of PET in anal canal cancer patients. The results showed that PET had high sensitivity and specificity in distinguishing T3/T4 stages and detecting metastatic disease. PET also showed good sensitivity and specificity in therapy response assessment. Furthermore, pre-treatment total metabolic tumour volume was found to be predictive of survival, and complete metabolic response was associated with better prognosis. Overall, PET may be a valuable tool in therapy planning and prognostic assessment for anal canal cancer.

Summary: This study compared functional connectivity and resting-state networks derived from fMRI and [F-18]FDG-PET scans in rats, finding that [F-18]FDG connectivity showed increased integration between brain areas compared to fMRI-derived FC. Additionally, independent component analysis revealed networks exclusive to either modality.

Summary: 2-deoxy-2[F-18]fluoro-D-glucose (FDG) PET-CT has revolutionized oncological imaging, and it is also widely used in the diagnosis and treatment of infectious and inflammatory diseases. Rheumatological diseases, which can affect multiple sites within the musculoskeletal system, can be accurately diagnosed and treated using FDG PET-CT.

Summary: A systematic review analyzed the pulmonary findings of [F-18]FDG PET/CT on asymptomatic COVID-19 patients, revealing that multiple ground-glass opacities and [F-18]FDG-avid thoracic lymph nodes were common patterns in PET/CT of asymptomatic patients with COVID-19. Postoperative COVID-19 patients should also pay attention to positive tuberculous chain lymph node metastasis.

Summary: This study aimed to assess the immunomodulatory effects of fluvoxamine in patients with mild to moderate COVID-19. The results showed that the combination therapy of fluvoxamine and favipiravir did not provide significant benefits in preventing disease progression in these patients, but it resulted in lower hospitalization rates, oxygen supplemental rates, intensive care rates, and mortality rates.

Summary: The combination treatment of Andrographis paniculata extract (APE) and favipiravir did not provide additional clinical and virological benefits in patients with mild to moderate COVID-19. However, APE may have potential advantages in preventing severe COVID-19 by early reduction of IL-1 beta levels, which needs further investigation.

Summary: The diagnostic performance of F-18-FES and F-18-FDG for initial staging of ER-positive breast cancer is comparable, but F-18-FES performs better for strongly ER-positive breast cancer. Combining F-18-FES and F-18-FDG may overcome the limitations of each tracer and achieve more accurate staging.

Summary: This study demonstrates that high neutralizing titer COVID-19 convalescent plasma therapy (CPT) combined with favipiravir (FPV) is non-inferior to sotrovimab in preventing hospitalization and severe outcomes in outpatients with mild-to-moderate COVID-19 and high-risk comorbidities. It highlights the potential of CPT-FPV as an alternative to neutralizing monoclonal antibodies like sotrovimab, particularly for emerging variants with spike protein mutations. The study's unique approach comparing a monoclonal antibody with CPT shows the efficacy of early intervention using high neutralizing antibody titer CPT, even in populations with a significant proportion of elderly patients. These findings are crucial in addressing the treatment challenges posed by the rapidly mutating SARS-CoV-2 virus and the need for adaptable therapeutic strategies.

Summary: The study investigated the effectiveness of inactivated and ChAdOx1 nCoV-19 vaccination in preventing household transmission of SARS-CoV-2. The results showed that completing two doses of the SARS-CoV-2 vaccine within 14-90 days led to a significant reduction in household transmission. Wearing masks also played a role in reducing the risk of transmission.
