Intrapartum Baby Electrocardiogram in Small- as well as Large-for-Gestational Age Fetuses.
The purpose of this review is to show the imaging findings in PGO, with special emphasis on the US appearance.
Mitoxantrone (MTX) is a synthetic compound used as a second line chemotherapeutic drug for prostate cancer. It has been reported to trigger immunogenic cell death (ICD) in animal model studies, but the underlying mechanism is not fully understood yet, especially not in prostate cancer cells.

ICD was determined by assessing the release of damage-associated molecular patterns (DAMPs) in the prostate cancer-derived cell lines LNCaP, 22RV1 and PC-3. Short hairpin RNAs (shRNAs) were used to knock down target gene expression. Phagocytosis was assessed using a dual labeling technology in dendric cells co-cultured with cancer cells. The PERK gene promoter was cloned for dual luciferase assays. Chromatin immunoprecipitation (ChIP) was used to determine p53 protein-DNA binding activity. Immunocompetent mice and murine RM-1 prostate cancer cells were used for vaccination experiments.

MTX treatment induced typical characteristics of DAMP release, including increased cell surface exposure of calreticulin (CALR), andncer cells. MTX-induced PERK expression upregulation depends on the p53 pathway, while that of GCN2 requires further investigation.Anaplastic large cell lymphoma (ALCL) accounts for 10-15% of childhood non-Hodgkin lymphoma cases; it is generally chemo-sensitive and is one of the most curable pediatric cancers. We report here a case of pediatric ALCL complicated with acute liver failure due to the aggravation of pre-existing biliary hepatopathy by lymphoma-associated hemophagocytic lymphohistiocytosis (HLH). Although the initial treatment response against ALCL was very good, poor and irreversible liver function due to biliary cirrhosis worsening by lymphoma-associated HLH prevented the patient from receiving further consolidation chemotherapies. To make matters worse, his condition was accompanied with intrahepatic fungal pseudoaneurysm and invasive fungal infection. Thus, we decided to perform an urgent living-donor liver transplantation from his father to correct the patient's liver function and make it possible to proceed with further ALCL therapy. After the living-donor liver transplantation, the patient successfully received consolidation therapy with brentuximab vedotin. To our knowledge, this may be an early reported case of a pediatric patient undergoing liver transplantation during treatment for ALCL. In most patients with HLH-associated ALCL, liver function improves when ALCL is controlled. However, acute liver failure is occasionally observed in HLH cases with pre-existing liver dysfunction. In such cases, liver transplantation should be considered to correct liver dysfunctions if the disease control of HLH is satisfactory.
Patients with multiple myeloma (MM) have increased risks of venous thromboembolism (VTE) and arterial thromboembolism (ATE). The risk of thrombosis differs among different treatment regimens. It is unknown if daratumumab could affect thrombosis risk.

A comprehensive search was conducted until April 2020. Events of VTE, including pulmonary embolism and deep venous thrombosis, as well as events of ATE, including acute ischemic stroke and myocardial infarction, were extracted from trials. In addition, events of thrombocytopenia and gastrointestinal (GI) bleeding were also extracted.

Six trials were included in the meta-analysis. Daratumumab was associated with a lower risk of VTE compared with non-daratumumab regimen (Risk ratio [RR], 0.60; 95% confidence interval [CI], 0.40-0.91). The risk of ATE had no significant difference (RR, 0.80; 95% CI, 0.48-1.33). Daratumumab was also associated with a trend of higher risk of Grade 3/4 thrombocytopenia (RR, 1.14; 95% CI, 0.94-1.38), while the risk of GI bleeding was not significantly different (RR, 1.32; 95% CI, 0.38-4.65).

Daratumumab is associated with lower risk of VTE in clinical trials.

Emergent hemodialysis was initiated combined with chemotherapy including bortezomib, lenalidomide, and pomalidomide, but myeloma had become refractory due to the treatments. Therefore, a combination therapy with weekly daratumumab (16 mg/kg), bortezomib (0.7 mg/m2), and dexamethasone was started. Daratumumab was administered on a non-dialysis day with a reduced infusion speed to avoid acute water load. Doxycycline molecular weight No infusion-related adverse events were observed throughout the treatment. Daratumumab and bortezomib were administrated weekly for three times in the first cycle and a hematological very good partial response was achieved. Then, the treatment schedule was reduced to once every three weeks from the 2nd cycle, the very good partial response had been maintained. Fourteen months after the initiation of maintenance hemodialysis, the patient was able to reduce dialysis frequency due to improvement of renal function. A modified daratumumab, bortezomib and dexamethasone regimen could be a valuable treatment option for dialysis-dependent myeloma patients.
Type 2 diabetes mellitus (T2DM) has been shown to negatively impact bone quality and increase fracture risk. While the pathophysiology of bone fragility in T2DM is not clear and likely multifactorial, medications used to treat T2DM are increasingly scrutinized for their potential role in aberrant bone metabolism. Sodium-glucose co-transporter 2 (SGLT2) inhibitors are gaining popularity in patients with T2DM. In addition to lowering blood glucose, there is evidence that these drugs offer cardiac and renal benefit to individuals with T2DM, leading to FDA-approved indications for use in at-risk individuals. At the same time, there remain concerns that SGLT2 inhibitors, specifically canagliflozin, have adverse effects on bone metabolism and increase fracture risk in T2DM. This review seeks to further clarify the impact of these agents on the skeleton.

SGLT2 inhibitors may indirectly disrupt calcium and phosphate homeostasis, contribute to weight loss, and cause hypotension, resulting in bone mineral density (BMD) losses and increased falls.
