0% with race alone. Lung only was the most common metastatic site (43.6%), followed by bone only (27.6%), liver only (4.4%), and brain only (4.4%). Of all the patients with SMs, 78.9% had a single metastatic site. CONCLUSIONS The SM rates showed very wide variation according to the HS, TG, and TS. When HS was combined with TG, TS, and race, SMs could be accurately predicted in individual patients better than with TS alone. Thus, renal mass biopsy-derived HS and TG could improve the prediction of SMs compared with using TS alone. BACKGROUND Patients with relapsed germ cell tumors (GCTs) can be cured with salvage chemotherapy. We evaluated the risk factors and outcomes of patients who had developed acute kidney injury (AKI) during high-dose chemotherapy (HDCT) for relapsed GCT. PATIENTS AND METHODS All patients were scheduled to receive 2 consecutive courses of HDCT per our standard protocol. The characteristics and outcomes of the patients with stage ≥ 3 AKI were analyzed and compared with those without stage ≥ 3 AKI. read more RESULTS Of 462 patients, 21 (4.5%) developed stage ≥ 3 AKI. Of these 21 patients, 18 had required hemodialysis during HDCT and 6 had died during HDCT. Of the 15 patients who had survived HDCT, 10 experienced recovery of renal function to baseline. AKI had occurred in the first cycle of HDCT in 18 patients. These patients were also more likely to have received HDCT in a third-line setting or further, to have Eastern Cooperative Oncology Group performance status of 1 or 2, and to have experienced gastrointestinal, hepatic, pulmonary, and infectious grade ≥ 3 toxicities. At a median follow-up of 10 months after HDCT, 4 patients had no evidence of disease, 3 were alive with disease, 6 had died of disease, 7 had died of complications from HDCT, and 1 had been lost to follow-up. CONCLUSIONS Irreversible AKI during HDCT for relapsed GCT is uncommon but is associated with greater rates of infectious, gastrointestinal, hepatic, and pulmonary complications and treatment-related death. These patients were also more heavily pretreated and had a lower baseline performance status. However, most surviving patients had recovered their renal function and 5 of 21 were alive with no evidence of disease. BACKGROUND We investigated, in a real-life setting, the prognostic relevance of previous primary treatment (radical prostatectomy [RP] or external beam radiotherapy [EBRT]) on overall survival for patients with metastatic castration-resistant prostate cancer (mCRPC) treated with radium-223 (223Ra). MATERIALS AND METHODS In the present multicenter retrospective study, we enrolled 275 consecutive patients. The demographic and clinical data and mCRPC characteristics were recorded and evaluated at baseline and at the end of treatment or progression. 223Ra was administered according to the current label authorization until disease progression or unacceptable toxicity. We divided the whole cohort into 2 groups those who had undergone primary radical prostatectomy or ablative radiotherapy (RP/EBRT) and those who had not received previous primary treatment (NO). RESULTS Of the 275 patients, 128 (46.5%) were alive and undergoing monitoring at the last follow-up examination, 103 (37.4%) had stopped treatment because of disease progression or the onset of comorbidities, and 147 (53.5%) had died during the study period. Of the 275 patients, 132 were in the RP/EBRT group (48%), of whom 93 had undergone RP and 76 had undergone ablative EBRT, and 143 patients were in the NO group (52%). The data showed a clear advantage for the patients in the RP/EBRT group compared with those in the NO group, with an estimated median survival of 18 versus 11 months, respectively (P less then .001). The results from the multivariate analysis corroborated this trend, with a hazard ratio of 0.7 (P = .0443), confirming the better outcome for the RP/EBRT group. CONCLUSIONS Previous radical treatment provides a protective role for patients with mCRPC undergoing 223Ra treatment. In South Asia, the "Big-4" venomous snakes Naja naja, Bungarus caeruleus, Daboia russelii, and Echis carinatus are so-called because they are the most medically important snakes in the region. Antivenom is the only effective treatment option for snakebite envenoming but antivenom is not produced domestically in Pakistan making the country reliant on polyvalent products imported from India and Saudi Arabia. The present study investigated the toxin composition and activity of the venoms of Pakistani specimens by means of proteomic and physio/pharmacological experiments. To evaluate the composition of venoms, 1D/2D-PAGE of crude venoms and RP-HPLC followed by SDS-PAGE were performed. Enzymatic, hemolytic, coagulant and platelet aggregating activities of crude venoms were assayed and were concordant with expectations based on the abundance of protein species in each. Neutralization assays were performed using Bharat polyvalent antivenom (BPAV), a product raised against venoms from Big-4 specimens from southern India. BPAV exhibited cross-reactivity against the Pakistani venoms, however, neutralization of clinically relevant activities was variable and rarely complete. Cumulatively, the presented data not only highlight geographical variations present in the venoms of the Big-4 snakes of South Asia, but also demonstrate the neutralization potential of Indian polyvalent against the venom of Pakistani specimens. Given the partial neutralization observed, it is clear that whilst BPAV is a life-saving product in Pakistan, in future it is hoped that a region-specific product might be manufactured domestically, using venoms of local snakes in the immunising mixture. Pathological cardiac hypertrophy is an independent risk for heart failure (HF) and sudden death. Deciphering signaling pathways regulating intracellular Ca2+ homeostasis that control adaptive and pathological cardiac growth may enable identification of novel therapeutic targets. The objective of the present study is to determine the role of the store-operated calcium entry-associated regulatory factor (Saraf), encoded by the Tmem66 gene, on cardiac growth control in vitro and in vivo. Saraf is a single-pass membrane protein located at the sarco/endoplasmic reticulum and regulates intracellular calcium homeostasis. We found that Saraf expression was upregulated in the hypertrophied myocardium and was sufficient for cell growth in response to neurohumoral stimulation. Increased Saraf expression caused cell growth, which was associated with dysregulation of calcium-dependent signaling and sarcoplasmic reticulum calcium content. In vivo, Saraf augmented cardiac myocyte growth in response to angiotensin II and resulted in increased cardiac remodeling together with worsened cardiac function.
