We investigated the association between variants rs12997 in activin A receptor type I (ACVR1) and rs1043784 in BMP6 located in the 3' untranslated region, and primary open-angle glaucoma (POAG). The retrospective case-control study used TaqMan real-time PCR assay to genotype 400 subjects, including 150 patients with POAG and 250 controls. The minor 'G' allele of rs12997 in ACVR1 showed significant association with POAG (p=0.027, OR=1.39, 95% CI=1.03 to 1.87). ⋯ However, clinical variables such as intraocular pressure and cup/disc ratio showed no association with both the polymorphisms. To conclude, the study shows a modest association between rs12997 in the ACVR1 gene, a member of the bone morphogenic protein signaling pathway and POAG. However, the results need further replication in large population-based cohorts and different ethnicities to validate its role as an important genetic biomarker.

The Pediatric Emergency Care Applied Research Network (PECARN) Head Injury/Trauma Algorithm is a well-validated decision rule used to identify patients at low risk of clinically important traumatic brain injuries who may not need head CT. In adult patients with mild head trauma, elevated serum glucose and white cell count (WCC) have been associated with abnormal head CT findings. Currently, glucose or WCC is not considered in pediatric patients. ⋯ Following multiple logistic regression analysis, WCC (OR 1.113, 95% CI 1.02 to 1.21), younger age (OR 0.89, 95% CI 0.8 to 0.98), and absence of other injuries (OR 0.41, 95% CI 0.23 to 0.73) were found to be associated with risk of ICI. The area under the curve for our model was 0.79. When used with the PECARN algorithm, our model could help determine which patients may avoid head CT or undergo a shorter observation period.

Acromegaly is a rare disease associated with comorbidities that are common in the general population. Most patients undergo screening for classic phenotypical (CP) or mass effect manifestations. By retrospective review of pituitary tumor surgeries performed between 1994 and 2016 (1836), we identified patients with acromegaly (112). ⋯ A similar number of patients had normal IGF-1 at last follow-up (89.5% ID and 81.25% CP) after surgery alone and multimodality treatment. In conclusion, an increased number of patients with GH-secreting adenomas were ID in recent years. Education of physicians other than endocrinologists regarding presentation and comorbidity clustering may lead to an earlier diagnosis of acromegaly and improved outcomes.

Assessing congestion is challenging but important to patients with chronic heart failure (CHF). However, there are limited data regarding the association between estimated plasma volume status (ePVS) determined using hemoglobin/hematocrit data and outcomes in patients with stable CHF. We prospectively analyzed 231 patients; the median follow-up period was 35.6 months. ⋯ In receiver operating characteristic analysis, the area under the curve of ePVS for primary outcome was 0.645. ePVS determined using hemoglobin and hematocrit was independently associated with clinical outcomes for patients with stable CHF. Our study thus further strengthens the evidence that ePVS has important prognostic value in patients with stable CHF. Trial registration number ChiCTR-ONC-14004463.

Acute suppurative parotitis (ASP) is an acute infection of the parotid gland that necessitates hospitalization in some patients. The aim of this study was to evaluate clinical laboratory values including hydration, nutritional status, inflammatory markers and age, and to compare them with duration of hospitalization of patients with ASP. This is a retrospective chart review in a tertiary academic center. ⋯ Examination of these factors on multivariate analysis found hospitalization duration was exclusively affected by patients' level of dehydration as represented by BUN:Cr. Patient age, WCC levels at presentation, and platelet levels were not found to be statistically significant. Treatment and interventions should be planned accordingly.
