The COVID-19 pandemic began in early 2020 with major health consequences. While a need to disseminate information to the medical community and general public was paramount, concerns have been raised regarding the scientific rigor in published reports. We performed a systematic review to evaluate the methodological quality of currently available COVID-19 studies compared to historical controls. A total of 9895 titles and abstracts were screened and 686 COVID-19 articles were included in the final analysis. Comparative analysis of COVID-19 to historical articles reveals a shorter time to acceptance (13.0[IQR, 5.0–25.0] days vs. 110.0[IQR, 71.0–156.0] days in COVID-19 and control articles, respectively; p  < 0.0001). Furthermore, methodological quality scores are lower in COVID-19 articles across all study designs. COVID-19 clinical studies have a shorter time to publication and have lower methodological quality scores than control studies in the same journal. These studies should be revisited with the emergence of stronger evidence. During the early phase of the COVID-19 pandemic there was a need for rapid dissemination of clinical findings. Here, Jung, Di Santo et al. perform a systematic review and cohort study providing evidence for lower methodological quality scores and faster time to publication of clinical studies related to COVID-19 than comparable studies.

Abstract Context The aldosterone to renin ratio (ARR) is the guideline-recommended screening test for primary aldosteronism. However, there are limited data in regard to the diagnostic performance of the ARR. Objective To evaluate the sensitivity and specificity of the ARR as a screening test for primary aldosteronism. Methods We searched the MEDLINE, Embase, and Cochrane databases until February 2020. Observational studies assessing ARR diagnostic performance as a screening test for primary aldosteronism were selected. To limit verification bias, only studies where dynamic confirmatory testing was implemented as a reference standard regardless of the ARR result were included. Study-level data were extracted and risk of bias and applicability were assessed using the QUADAS-2 tool. Results Ten studies, involving a total of 4110 participants, were included. Potential risk of bias related to patient selection was common and present in half of the included studies. The population base, ARR positivity threshold, laboratory assay, and reference standard for confirmatory testing varied substantially between studies. The reported ARR sensitivity and specificity varied widely with sensitivity ranging from 10% to 100% and specificity ranging from 70% to 100%. Notably, 3 of the 10 studies reported an ARR sensitivity of <50%, suggesting a limited ability of the ARR to adequately identify patients with primary aldosteronism. Conclusions ARR performance varied widely based on patient population and diagnostic criteria, especially with respect to sensitivity. Therefore, no single ARR threshold for interpretation could be recommended. Limitations in accuracy and reliability of the ARR must be recognized in order to appropriately inform clinical decision-making.

IL-10 has anti-inflammatory and CD8+ T-cell stimulating activities. Pegilodecakin (pegylated IL-10) is a first-in-class, long-acting IL-10 receptor agonist that induces oligoclonal T-cell expansion and has single-agent activity in advanced solid tumours. We assessed the safety and activity of pegilodecakin with anti-PD-1 monoclonal antibody inhibitors in patients with advanced solid tumours. We did a multicentre, multicohort, open-label, phase 1b trial (IVY) at 12 cancer research centres in the USA. Patients were assigned sequentially into cohorts. Here, we report on all enrolled patients from two cohorts treated with pegilodecakin combined with anti-PD-1 inhibitors. Eligible patients were aged at least 18 years with histologically or cytologically confirmed advanced malignant solid tumours refractory to previous therapies, and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients with uncontrolled infectious diseases were excluded. Pegilodecakin was provided in single-use 3 mL vials and was self-administered subcutaneously by injection at home at 10 μg/kg or 20 μg/kg once per day in combination with pembrolizumab (2 mg/kg every 3 weeks or 200 mg every 3 weeks) or nivolumab (3 mg/kg every 2 weeks or 240 mg every 2 weeks or 480 mg every 4 weeks at the approved dosing), both of which were given intravenously at the study site. Patients received pembrolizumab or nivolumab with pegilodecakin until disease progression, toxicity necessitating treatment discontinuation, patient withdrawal of consent, or study end. The primary endpoints were safety and tolerability, assessed in all patients enrolled in the study who received any amount of study medication including at least one dose of pegilodecakin, and pharmacokinetics (previously published). Secondary endpoints included objective response by immune-related response criteria in all patients who were treated and had evaluable measurements. The study is active but no longer recruiting, and is registered with ClinicalTrials.gov, NCT02009449. Between Feb 13, 2015, and Sept 12, 2017, 111 patients were enrolled in the two cohorts. 53 received pegilodecakin plus pembrolizumab, and 58 received pegilodecakin plus nivolumab. 34 (31%) of 111 patients had non-small-cell lung cancer, 37 (33%) had melanoma, and 38 (34%) had renal cell carcinoma; one (<1%) patient had triple-negative breast cancer and one (<1%) had bladder cancer. Data cutoff was July 1, 2018. Median follow-up was 26·9 months (IQR 22·3–31·5) for patients with non-small-cell lung cancer, 33·0 months (29·2–35·1) for those with melanoma, and 22·7 months (20·9–27·0) for those with renal cell carcinoma. At least one treatment-related adverse event occurred in 103 (93%) of 111 patients. Grade 3 or 4 events occurred in 73 (66%) of 111 patients (35 [66%] of 53 in the pembrolizumab group and 38 [66%] of 58 in the nivolumab group), the most common of which were anaemia (12 [23%] in the pembrolizumab group and 16 [28%] in the nivolumab group), thrombocytopenia (14 [26%] in the pembrolizumab group and 12 [21%] in the nivolumab group), fatigue (11 [21%] in the pembrolizumab group and 6 [10%] in the nivolumab group) and hypertriglyceridaemia (three [6%] in the pembrolizumab group and eight [14%] in the nivolumab group). There were no fatal adverse events determined to be related to the study treatments. Of the patients evaluable for response, objective responses were 12 (43%) of 28 (non-small-cell lung cancer), three (10%) of 31 (melanoma), and 14 (40%) of 35 (renal cell carcinoma). In this patient population, pegilodecakin with anti-PD-1 monoclonal antibodies had a manageable toxicity profile and preliminary antitumour activity. Pegilodecakin with pembrolizumab or nivolumab could provide a new therapeutic opportunity for previously treated patients with renal cell carcinoma and non-small-cell carcinoma.

Background Pancreatic cancer has a poor prognosis and few choices of therapy. For patients with adequate performance status, FOLFIRINOX or gemcitabine plus nab-paclitaxel are preferred first-line treatment. 5-Fluorouracil (5-FU)–based therapy (e.g. FOLFIRI, OFF, or FOLFOX) are often used in patients who previously received gemcitabine-based regimens. A systematic review was conducted of the safety and efficacy of FOLFOX for metastatic pancreatic cancer following prior gemcitabine-based therapy. A Bayesian fixed-effect meta-analysis with adjustment of patient performance status (PS) was conducted to evaluate overall survival (OS) and compare outcomes with nanoliposomal irinotecan combination therapy. Methods PubMed.gov , FDA.gov , ClinicalTrials.gov , congress abstracts, Cochrane.org library, and EMBASE database searches were conducted to identify randomized controlled trials of advanced/metastatic disease, prior gemcitabine-based therapy, and second-line treatment with 5-FU and oxaliplatin. The database search dates were January 1, 1990–June 30, 2019. Endpoints were OS and severe treatment-related adverse events (TRAEs). Trial-level PS scores were standardized by converting Karnofsky grade scores to Eastern Cooperative Oncology Group (ECOG) Grade, and overall study-weighted PS was calculated based on weighted average of all patients. Results Of 282 studies identified, 11 randomized controlled trials ( N  = 454) were included in the meta-analysis. Baseline weighted PS scores predicted OS in 10 of the 11 studies, and calculated PS scores of 1.0 were associated with a median OS of 6.3 months (95% posterior interval, 5.4–7.4). After adjusting for baseline PS, FOLFOX had a similar treatment effect profile (median OS, range 2.6–6.7 months) as 5-FU/leucovorin plus nanoliposomal irinotecan therapy (median OS, 6.1 months; 95% confidence interval 4.8–8.9). Neutropenia and fatigue were the most commonly reported Grade 3–4 TRAEs associated with FOLFOX. Conclusions Baseline PS is a strong prognostic factor when interpreting the efficacy of 5-FU and oxaliplatin-based therapy of pancreatic cancer after progression on first-line gemcitabine-based regimens. When baseline PS is considered, FOLFOX has a similar treatment effect as 5-FU and nanoliposomal irinotecan therapy and a comparable safety profile. These findings suggest that 5-FU and oxaliplatin-based therapies remain an acceptable and alternative second-line treatment option for patients with pancreatic cancer and adequate PS (e.g. ECOG 0–1) following gemcitabine treatment.

Patients undergoing antiviral therapy for chronic hepatitis C often develop anemia secondary to ribavirin and interferon. Recombinant erythropoietin has been used to improve anemia associated with antiviral therapy and to minimize dose reductions, which are associated with decreased rates of sustained virologic response. A rare potential side effect of recombinant erythropoietin is anti-erythropoietin antibody associated pure red cell aplasia. In chronic kidney disease patients with this entity, there have been good outcomes associated with renal transplant and subsequent immunosuppression. In this case, a chronic liver disease patient developed anti-erythropoietin associated pure red cell aplasia and recovered after liver transplantation and immunosuppression. It is unclear whether it is the transplanted organ, the subsequent immunosuppression, or the combination that contributed to the response. In conclusion, anti-erythropoietin associated pure red cell aplasia is a serious complication of erythropoietin therapy, but this entity should not be considered a contraindication for solid organ transplantation.

SummaryBackground Treatment options for pancreatic ductal adenocarcinoma (PDAC) are limited and checkpoint blockade inhibitors have been disappointing in this disease. Pegilodecakin has demonstrated single agent anti-tumor activity in immune-sensitive tumors. Phase 1 and preclinical data indicate synergy of pegilodecakin with 5-FU and platins. We assessed the safety and activity of pegilodecakin+FOLFOX in patients with PDAC. Methods IVY (NCT02009449) was an open-label phase 1b trial in the United States. Here we report on all enrolled patients from cohort C. Heavily pretreated patients were treated with pegilodecakin (self-administered subcutaneously daily at 2.5, 5, or 10 μg/kg) + 5-flurouracil/leucovorin/oxaliplatin (FOLFOX), dosed per manufacturers prescribing information, until tumor progression. Eligible patients had measurable disease per immune-related response criteria (irRC), were ≥ 18 years of age, and had ECOG performance status of 0 or 1. Patients were evaluated for primary(safety) and secondary (tumor response per irRC) endpoints. Results From 5 August 2014–12 July 2016, 39 patients enrolled in cohort C. All patients were evaluable for safety. In this advanced population, regimen had manageable toxicities with no immune-related adverse events (irAEs) greater than grade 1. The most common grade 3/4/5 TEAEs were thrombocytopenia (21[53.8%] of 39) and anemia (17[43.6%] of 39). In evaluable PDAC patients, the best overall response of pegilodecakin+FOLFOX was 3(14%) with CRs in 2(9%) patients. Conclusions Pegilodecakin+FOLFOX had an acceptable tolerability profile in PDAC, with no substantial irAEs seen, and promising efficacy with the combination yielding a 2-year OS of 24% (95% CI 10–42). These data led to the phase 3 study with pegilodecakin+FOLFOX as second-line therapy of PDAC (SEQUOIA).

Alternate Routes, an arts program by the local non-profit organization Side Street Projects (SSP), brings woodworking to elementary school children via their colorful buses. Decorated with bright murals by local artists, the mobile workshops are equipped with enough wood and hand tools to accommodate sessions of 10 students at a time. \"Woodworking is an exercise in spatial problem solving,\" said [Jon Lapointe]. While the workshops are meant to be fun, he said, they are also meant to build children's confidence with tools and teach scale, pattern and proportion. The program fulfills requirements outlined in the state's Education Standards for Visual Arts and Mathematics. Both Lapointe and Lujan attribute Alternate Routes' burgeoning success to the support of the Pasadena community. This summer, the City of Pasadena Cultural Grant has brought the program to several local schools, including the Sierra Madre Elementary, Franklin Elementary and Mayfield Junior schools.
