TL;DR: The temporal association between pamidronate therapy and the development of renal insufficiency, the use of escalating doses that exceed recommended levels, and the distinctive pattern of glomerular andtubular injury strongly suggest a mechanism of drug-associated podocyte and tubular toxicity.
Abstract: Collapsing focal segmental glomerulosclerosis (FSGS) is a distinct clinicopathologic entity seen most commonly in young African American patients who present with renal insufficiency and nephrotic syndrome. The only epidemiologic factor previously linked to collapsing FSGS is HIV infection. Here clinicopathologic findings are reported for a distinctive population of seven patients, who were older, Caucasian, and HIV negative and developed collapsing FSGS during active treatment of malignancy (multiple myeloma in six patients and metastatic breast carcinoma in one). Although oncologic treatment regimens included vincristine for four patients, doxorubicin for five patients, cisplatin for two patients, and total-body irradiation for one patient, the only agent common to all patients was pamidronate (Aredia). All patients had normal renal function before the administration of pamidronate. Patients began therapy with pamidronate at or below the recommended dose of 90 mg, intravenously, monthly, which was increased to 180 mg monthly in two patients and 360 mg monthly in three patients. Patients received pamidronate for 15 to 48 mo before presentation with renal insufficiency (mean serum creatinine, 3.6 mg/dl) and full nephrotic syndrome (mean 24-h urinary protein excretion, 12.4 g/d). Pamidronate, which is a member of the class of bisphosphonates, is widely used in the treatment of hypercalcemia of malignancy and osteolytic metastases. At the recommended dose of 90 mg, intravenously, monthly, renal toxicity is infrequent; however, higher doses have produced nephrotoxicity in animal models. The temporal association between pamidronate therapy and the development of renal insufficiency, the use of escalating doses that exceed recommended levels, and the distinctive pattern of glomerular and tubular injury strongly suggest a mechanism of drug-associated podocyte and tubular toxicity. These data provide the first association of collapsing FSGS with toxicity to a therapeutic agent.
TL;DR: In insight into the relationship between tumor dissemination and metabolic attributes of human cancer stem cells, spheroid cells were found to be enriched for cells with cancer stem cell-like characteristics and contributed to tumor generation, progression and chemotherapy resistance.
Abstract: Cells with sphere forming capacity, spheroid cells, are present in the malignant ascites of patients with epithelial ovarian cancer (EOC) and represent a significant impediment to efficacious treatment due to their putative role in progression, metastasis and chemotherapy resistance. The exact mechanisms that underlie EOC metastasis and drug resistance are not clear. Understanding the biology of sphere forming cells may contribute to the identification of novel therapeutic opportunities for metastatic EOC. Here we generated spheroid cells from human ovarian cancer cell lines and primary ovarian cancer. Xenoengraftment of as few as 2000 dissociated spheroid cells into immune-deficient mice allowed full recapitulation of the original tumor, whereas >105 parent tumor cells remained non-tumorigenic. The spheroid cells were found to be enriched for cells with cancer stem cell-like characteristics such as upregulation of stem cell genes, self-renewal, high proliferative and differentiation potential, and high aldehyde dehydrogenase (ALDH) activity. Furthermore, spheroid cells were more aggressive in growth, migration, invasion, scratch recovery, clonogenic survival, anchorage-independent growth, and more resistant to chemotherapy in vitro. 13C-glucose metabolic studies revealed that spheroid cells route glucose predominantly to anaerobic glycolysis and pentose cycle to the detriment of re-routing glucose for anabolic purposes. These metabolic properties of sphere forming cells appear to confer increased resistance to apoptosis and contribute to more aggressive tumor growth. Collectively, we demonstrated that spheroid cells with cancer stem cell-like characteristics contributed to tumor generation, progression and chemotherapy resistance. This study provides insight into the relationship between tumor dissemination and metabolic attributes of human cancer stem cells and has clinical implications for cancer therapy.
TL;DR: Dual-site right atrial pacing is safe, achieves long-term rhythm control in most patients, decreases the need for cardioversion, and antithrombotic therapy can be selectively reduced.
Abstract: Objectives. An initial crossover study comparing dual- and single-site right atrial pacing was performed followed by a long-term efficacy and safety evaluation of dual-site right atrial pacing in patients with drug-refractory atrial fibrillation (AF). Also examined was the efficacy of two single-site right atrial pacing modes (high right atrium and coronary sinus ostium) and the long-term need for cardioversion, antithrombotic and antiarrhythmic drug therapies during dual-site atrial pacing. Methods. Thirty consecutive patients with drug-refractory symptomatic AF and documented primary or drug-induced bradycardia were implanted with a dual chamber rate-responsive pacemaker and two atrial leads. Single-site atrial pacing was performed at the high right atrium or the coronary sinus ostium. Continuous atrial pacing was maintained. Results. Mean arrhythmia-free intervals increased from 9 ± 10 days in the control period preceding implant to 143 ± 110 days (p Conclusions. Atrial pacing in combination with antiarrhythmic drugs eliminates or markedly reduces recurrent AF. Prevention of AF is enhanced by dual-site right atrial pacing. High right atrial and coronary sinus ostial pacing do not differ in efficacy. Dual-site right atrial pacing is safe, achieves long-term rhythm control in most patients, decreases the need for cardioversion, and antithrombotic therapy can be selectively reduced.

TL;DR: Parents' perceptions of QoL for children with FAP were lower than their children's self-reported scores, highlighting the clinical significance of FAP and providing insight into one facet of the disease's biopsychosocial etiology.
Abstract: OBJECTIVE. Children with chronic abdominal pain of nonorganic origin, termed functional abdominal pain (FAP), experience school absences and social withdrawal and report impaired physical ability. The aim of this study was to assess patients9 and parents9 perceptions of health-related quality of life (QoL) for children with FAP. METHODS. Between October 2002 and November 2003, 209 children (including 125 girls; age: 11.2 ± 3.5 years) and 209 parents were recruited from a pediatric referral center. At the time of their initial evaluations, participants completed a validated, health-related QoL instrument (Pediatric Quality of Life Inventory), which was scored on a scale of 0 (poor) through 100 (best). Children with FAP (n = 65) and their families were compared with control groups of healthy children (n = 46) and children with histologically proven inflammatory bowel disease (IBD) (n = 42) or gastroesophageal reflux disease (GERD) (n = 56). RESULTS. Children with FAP had self-reported QoL scores (score: 78) that were similar to those for children with GERD (score: 80) or IBD (score: 84). Children with FAP had lower QoL scores than did healthy children (score: 88). Parents of children with FAP reported lower QoL scores, compared with their children9s scores (scores: 70 vs 78). CONCLUSIONS. Children with FAP reported lower QoL, compared with their healthy peers, and had the same QoL scores as did children with IBD or GERD. Parents9 perceptions of QoL for children with FAP were lower than their children9s self-reported scores. These findings highlight the clinical significance of FAP and may provide insight into one facet of the disease9s biopsychosocial etiology.

TL;DR: Antiangiogenic therapy using bevacizumab appears to improve survival in patients with recurrent high-grade glioma, and a possible change in the invasiveness of the tumor following therapy is worrisome and must be closely monitored.
Abstract: Object Antiangiogenic agents have recently shown impressive radiological responses in high-grade glioma. However, it is not clear if the responses are related to vascular changes or due to antitumoral effects. The authors report the mature results of a clinical study of bevacizumab-based treatment of recurrent high-grade gliomas. Methods Sixty-one patients with recurrent high-grade gliomas received treatment with bevacizumab at 10 mg/ kg every 2 weeks for 4 doses in an 8-week cycle along with either irinotecan or carboplatin. The choice of concomitant chemotherapeutic agent was based on the number of recurrences and prior chemotherapy. Results At a median follow-up of 7.5 months (range 1–19 months), 50 (82%) of 61 patients relapsed and 42 patients (70%) died of the disease. The median number of administered bevacizumab cycles was 2 (range 1–7 cycles). The median progression-free survival (PFS) and overall survival (OS) were 5 (95% confidence interval [CI] 2.3–7.7) and 9 (95% CI 7.6–10.4) months, respectiv...
