#1
Zaina T Al-Salama, Gillian M Keating
The multiple tyrosine kinase inhibitor (TKI) cabozantinib (Cabometyx™) is approved in the USA for the treatment of patients with advanced renal cell carcinoma (RCC) who have received prior antiangiogenic therapy. In the EU, cabozantinib is indicated for the treatment of advanced RCC in adults following prior vascular endothelial growth factor (VEGF)-targeted therapy. In adults with advanced or metastatic clear-cell RCC who had previously received VEGF receptor (VEGFR) TKIs, progression-free survival (PFS) and overall survival (OS) were significantly prolonged in patients who received oral cabozantinib versus oral everolimus in the pivotal METEOR trial...

T F Tammam, A F Salama
BACKGROUND: Under laparoscopic guidance, block of ilioinguinal, iliohypogastric, and genitofemoral nerves can be possible with anesthetic injection in the plane between psoas major and the fasciae covering its anterior aspects [laparoscopic-assisted psoas (LAP) blockade]. This observer-blinded trial aimed to compare the opioid-sparing effect of LAP block with transversus abdominis plane (TAP) block after laparoscopic inguinal herniorrhaphy. METHODS: Forty-five male patients were randomly assigned to receive LAP block, group LAP (n = 23), or ultrasound-guided TAP block, group TAP (n = 22)...

Pediatric lymphoma is common in sub-Saharan Africa, where survival estimates are often based on limited follow-up with incomplete retention, introducing potential for bias. We compared follow-up and overall survival (OS) between passive and active tracing within a prospective cohort of children with lymphoma in Malawi. Median follow-up times were 4.4 months (interquartile range [IQR] 2.0-9.4) and 10.8 months (IQR 6.2-20.6) in passive and active follow-up, respectively. Twelve-month overall survival (OS) was 69% (95% confidence interval [CI] 54-80) in passive and 44% (95% CI 34-54) in active follow-up...

REVIEW
Julian C Hong, Joseph K Salama
The spectrum hypothesis posits that there are distinct clinical states of metastatic progression. Early data suggest that aggressive treatment of more biologically indolent metastatic disease, characterized by metastases limited in number and destination organ, may offer an opportunity to alter the disease course, potentially allowing for longer survival, delay of systemic therapy, or even cure. The development of stereotactic body radiation therapy (SBRT) has opened new avenues for the treatment of oligometastatic disease...

Herpes simplex virus (HSV) hepatitis represents a rare complication of HSV infection, which can progress to acute liver failure and, in some cases, death. We describe an immunocompetent 67-year-old male who presented with one week of fever and abdominal pain. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the abdomen showed multiple bilobar hepatic lesions, some with rim enhancement, compatible with liver abscesses. Subsequent liver biopsy, however, revealed hepatocellular necrosis, HSV-type intranuclear inclusions, and immunostaining positive for herpes virus type 2 (HSV-2)...

BACKGROUND: Phosphatidylserine is the phospholipid component which plays a key role in cell cycle signaling, specifically in regards to necrosis and apoptosis. When a cell affected by some negative factors, phosphatidylserine is no longer restricted to the intracellular side of membrane and can be translocated to the extracellular surface of the cell. Cryopreservation can induce translocation of phosphatidylserine in response to hypoxia, increasing intracellular Ca(2+), osmotic disruption of cellular membranes, generation of reactive oxygen species and lipid peroxidation...

Current treatments for Hepatitis C virus (HCV) have severe side effects and are very expensive. There is a need to explore effective natural therapies against HCV that are less toxic and more cost-effective. In the current study, 37 chronic HCV patients were randomized into two groups and treated with either pegylated interferon (PEG IFN) plus ribavirin (n = 21) or Biobran, an arabinoxylan from rice bran (1 g/day) (n = 16). We examined viremia, liver enzymes, interferon-γ (IFN-γ) levels in serum, and toxicity before and three months after treatment...

Immunological molecules are implicated in inflammatory disorders, including IBD [CD and UC]. A further group of genetically variable proteins involved in immune function are killer cell immunoglobulin-like receptors (KIRs). These are expressed by NK cells and certain T lymphocytes where they regulate specificity and function by interaction with HLA Class I molecules. KIRs may either be inhibitory or activating and are polymorphic both in terms of alleles and haplotype gene content. Genetic associations of activating KIRs with certain autoimmune and inflammatory diseases have been demonstrated...
