TL;DR: This is the first report of defective FasL-mediated apoptosis related to a mutation of the human Fasl, gene in a patient with SLE and suggests that fasL mutations are an uncommon cause of the disease.
Abstract: The pathogenesis of systemic lupus erythematosus (SLE) is multifactorial and multigenetic. The apoptosis genes, fas and fas ligand (fasL), are candidate contributory genes in human SLE, as mutations of these genes result in autoimmunity in several murine models of this disease. In humans, fas mutations result in a familial autoimmune lymphoproliferative syndrome, but defects in FasL have not yet been identified. In this study, DNA from 75 patients with SLE was screened by single-stranded conformational polymorphism analysis for potential mutations of the extracellular domain of FasL. A heterozygous single-stranded conformational polymorphism for FasL, was identified in one SLE patient, who exhibited lymphadenopathy. Molecular cloning and sequencing indicated that the genomic DNA of this patient contained an 84-bp deletion within exon 4 of the fasL gene, resulting in a predicted 28 amino acid in-frame deletion. Analysis of PBMC from this patient revealed decreased FasL activity, decreased activation-induced cell death, and increased T cell proliferation after activation. This is the first report of defective FasL-mediated apoptosis related to a mutation of the human Fasl, gene in a patient with SLE and suggests that fasL mutations are an uncommon cause of the disease.

TL;DR: Standard-dose and high-dose biological drugs (with or without traditional DMARDs) are associated with an increase in serious infections in rheumatoid arthritis compared with traditionalDMARDs, although low- dose biological drugs are not.

TL;DR: Intrapartum‐related neonatal deaths (“birth asphyxia”) are a leading cause of child mortality globally, outnumbering deaths from malaria, yet there is a lack of consensus on what works, especially in weak health systems.

TL;DR: Long-term follow-up was obtained on 726 women with advanced ovarian carcinoma who had received primary chemotherapy on two Gynecologic Oncology Group (GOG) protocols between 1976 and 1982, and cisplatin treatment was beneficial.
Abstract: Long-term follow-up was obtained on 726 women with advanced ovarian carcinoma (suboptimal stage III and stage IV) who had received primary chemotherapy on two Gynecologic Oncology Group (GOG) protocols between 1976 and 1982. The first study compared melphalan alone versus melphalan plus hexamethylmelamine versus cyclophosphamide plus doxorubicin (CA). The second study evaluated the same CA regimen with or without cisplatin. Eligibility for the two studies was the same. At last contact, 76 patients were alive. In a multivariate analysis, cell type other than clear cell or mucinous, cisplatin-based treatment, good performance status, younger age, lower stage, clinically nonmeasurable disease, smaller residual tumor volume, and absence of ascites were favorable characteristics for overall survival (P less than .05). Second-look laparotomy was negative significantly more often among those with endometrioid tumors; there were no negative second-look laparotomies among those with mucinous or clear cell tumors. There were 30 patients with suboptimal stage III disease who had a negative second-look laparotomy; 18 (60%) have experienced recurrence, and 13 (43%) have died. Although cisplatin treatment was beneficial, new treatments are clearly needed.

TL;DR: Post hoc analyses reveal several potential confounding factors that may partially explain the unexpected blood pressure responses in both the sham control and RDN groups.
Abstract: Aims The SYMPLICITY HTN-3 randomized, blinded, sham-controlled trial confirmed the safety of renal denervation (RDN), but did not meet its primary efficacy endpoint. Prior RDN studies have demonstrated significant and durable reductions in blood pressure. This analysis investigated factors that may help explain these disparate results. Methods and results Patients with resistant hypertension were randomized 2 : 1 to RDN ( n = 364) or sham ( n = 171). The primary endpoint was the difference in office systolic blood pressure (SBP) change at 6 months. A multivariable analysis identified predictors of SBP change. Additional analyses examined the influence of medication changes, results in selected subgroups and procedural factors. Between randomization and the 6-month endpoint, 39% of patients underwent medication changes. Predictors of office SBP reduction at 6 months were baseline office SBP ≥180 mmHg, aldosterone antagonist use, and non-use of vasodilators; number of ablations was a predictor in the RDN group. Non-African-American patients receiving RDN had a significantly greater change in office SBP than those receiving sham; –15.2 ± 23.5 vs. –8.6 ± 24.8 mmHg, respectively ( P = 0.012). Greater reductions in office and ambulatory SBP, and heart rate were observed with a higher number of ablations and energy delivery in a four-quadrant pattern. Conclusions Post hoc analyses, although derived from limited patient cohorts, reveal several potential confounding factors that may partially explain the unexpected blood pressure responses in both the sham control and RDN groups. These hypothesis-generating data further inform the design of subsequent research to evaluate the potential role of RDN in the treatment of resistant hypertension.
