BACKGROUND: Chemotherapy for breast cancer is associated with a high risk of neutropenia. Pegfilgrastim reduces the risk of neutropenic fever but commonly causes bone pain. OBJECTIVE: Evaluate whether a reduced dose of pegfilgrastim (3 mg) reduced the frequency of bone pain without compromising efficacy. METHODS: Records reviewed from breast cancer patients who received at least one 3 mg dose of pegfilgrastim, white blood count (WBC), and absolute granulocyte counts (AGC) were collected...

Leukocyte adhesion deficiency type 1 (LAD-1) is a rare autosomal recessive disorder caused by mutations in the gene that codes for CD18, the beta chain of beta-2 integrins, located on the long arm of chromosome 21. This defect results in failure of leukocyte migration to the site of infection due to the absence of surface integrins. Leukocyte adhesion deficiency should be suspected in any patient with recurrent infections, impaired wound healing, history of delayed umbilical cord separation, periodontitis, leukocytosis, recurrent soft tissue and oral infections...

Background Mutations in the gene encoding isocitrate dehydrogenase 1 ( IDH1) occur in 6 to 10% of patients with acute myeloid leukemia (AML). Ivosidenib (AG-120) is an oral, targeted, small-molecule inhibitor of mutant IDH1. Methods We conducted a phase 1 dose-escalation and dose-expansion study of ivosidenib monotherapy in IDH1-mutated AML. Safety and efficacy were assessed in all treated patients. The primary efficacy population included patients with relapsed or refractory AML receiving 500 mg of ivosidenib daily with at least 6 months of follow-up...

Group B streptococcus infections (GBSI) are commonly associated with neonates and pregnant women, but may also affect nonpregnant adults. Among its spectrum of manifestations, perinephric abscess (PA) is exceedingly rare. Comorbid conditions such as diabetes mellitus (DM) and immunosuppression increase the risk of GBSI. We describe a 61-year-old Vietnamese man with compensated alcoholic cirrhosis, who presented with acute encephalopathy following subacute, progressive abdominal pain. He was afebrile and hemodynamically stable...

INTRODUCTION: Single institution studies suggest a benefit of a week of preoperative antibiotics prior to percutaneous nephrolithotomy (PCNL). These studies are limited by lower quality methodology such as the inclusion of heterogeneous populations or the use of non-standard definitions of sepsis. The American Urological Association (AUA) Best Practice Statement recommends <24 hours of IV antibiotics, but no other data exist about the duration/benefit of preoperative antibiotics. We sought to perform a rigorous (using CONSORT guidelines), multi-institutional trial to assess preoperative antibiotics in PCNL patients at low risk of developing infections...

PURPOSE OF REVIEW: Leukocytosis, elevated blood leukocyte levels, is associated with enhanced cardiovascular risk in humans. Hematopoietic stem and progenitor cells (HSPCs) drive leukocyte production in a process called hematopoiesis, which mainly occurs in the bone marrow, and under certain conditions also in other organs such as the spleen. Cholesterol accumulation in HSPCs enhances hematopoiesis, increasing levels of blood monocytes that infiltrate into atherosclerotic plaques. Although HSPC proliferation and monocytosis enhance atherogenesis in several studies, concomitant decreases in LDL-cholesterol levels have also been reported, associated with anti-atherogenic effects...

Despite high vaccination rates, the incidence of whooping cough has steadily been increasing in developing countries for several decades. The current acellular pertussis (aP) vaccines all include the major protective antigen pertussis toxin (PTx) and are safer, but they appear to be less protective than infection or older, whole-cell vaccines. To better understand the attributes of individual antibodies stimulated by aP, we isolated plasmablast clones recognizing PTx after booster immunization of two donors...
