A Formalization Framework for Integrating Social Design Intentions into Digital Building Models
Human-centered qualities (e.g., privacy, sense of orientation, etc.) significantly impact the social sustainability of buildings and the well-being of their occupants. However, due to their subjective nature, such qualities are often implicit and are not documented properly during the planning phase of construction projects. While several types of design intentions are documented throughout the lifecycle of building projects, intentions that are socially oriented and target soft aspects that reflect occupants’ experience (e.g., comfort, well-being, etc.), are evidently missing from current digital building models, hence risking constructing uninhabitable or socially unsustainable buildings. Through an extensive interdisciplinary collaboration between building scientists, practicing architects, and computer scientists, this paper addresses this gap by introducing a formalization framework, “ProFormalize”, to capture social design intentions (SDIs) in digital building models. This work presents a novel approach to digitalize SDIs in buildings, bridging a critical gap between architectural design intentions and explicit digital representations. Following a case-study-driven approach and a co-creation-based methodology, we developed the framework aiming to establish the foundations for developing a decision-support software tool (plugin) that enables architects, who are directly involved in the research process, to integrate SDIs into digital building models. The expert feedback demonstrates that the framework can make implicit SDIs explicit, which enables architects to integrate them into digital building models. Expert feedback suggested that a software tool developed based on this framework can enhance decision-making due to the traceability and analyzability of digital models.
Balanced crystalloids versus isotonic saline in critically ill patients: systematic review and meta-analysis
Objectives Intravenous fluids are one of the most used medical therapy for patients, especially critically ill patients. We conducted a meta-analysis comparing between balanced crystalloids and normal saline in critically ill patients and its effect on various clinical outcomes. Design Meta-analysis and systematic review of randomized clinical trials (RCTs). Methods and data source Electronic search was performed using PubMed, Cochrane library, and clinical trials.gov from inception through March 1, 2018, with inclusion of prospective studies that investigated one of the primary outcomes which were acute kidney injury (AKI) and in-hospital mortality while secondary outcomes were intensive care unit (ICU) mortality and new renal replacement therapy (RRT). Results Six RCTs were included. Total of 19,332 patients were included in the final analysis. There was no significant difference in in-hospital mortality (11.5% vs 12.2%; OR 0.92; 95% CI 0.85–1.01; P  = 0.09; I 2  = 0%), incidence of AKI (12% vs 12.7%, OR 0.92; 95% CI 0.84–1.01; P  = 0.1; I 2  = 0), overall ICU mortality (OR 0.9, 95% CI 0.81–1.01, P  = 0.08, I 2  = 0%), or need for new RRT (OR 0.92, 95% CI 0.67–1.28, P  = 0.65, I 2  = 38%) between balanced crystalloids and isotonic saline in critically ill patients. Conclusion Balanced crystalloids and isotonic saline have no difference on various clinical outcomes including in-hospital mortality, AKI, overall ICU mortality, and new RRT. Further powerful clinical trials are required to determine the relationship between crystalloid fluid type and clinical outcomes.
Use of glucocorticoids in patients with acute respiratory distress syndrome: a meta-analysis and trial sequential analysis
Background Acute respiratory distress syndrome (ARDS) is a common and disabling disease with high rates of mortality and morbidity. The role of steroids in treating ARDS remains controversial. We aim to examine the evidence behind using glucocorticoids in the management of ARDS from the available studies. Methods We performed a literature review of major electronic databases for randomized controlled trials (RCTs) comparing glucocorticoids versus placebo in treating patients with ARDS. Our primary outcome was hospital mortality. Other outcomes included ICU mortality, number of ventilator-free days at day 28, incidence of nosocomial infections, and hyperglycemia. We performed a meta-analysis using a random effects model to calculate risk ratios (RR) and mean difference (MD) with their corresponding 95% confidence intervals (CI). A subsequent trial sequential analysis was performed to examine the strength of evidence and to guard against statistical type I and type II errors for our results. Results Eight RCTs were included in the final analysis totaling of 1091 patients, with a mean age of 57 ± 16, and 56.2% were male. In our pooled analysis, use of glucocorticoids was associated with a significant reduction in hospital mortality (RR 0.79; 95% CI 0.64–0.98; P = 0.03) and ICU mortality (RR 0.64; 95% CI 0.42–0.97; P = 0.04). Furthermore, glucocorticoid use was associated with an increased number of ventilator-free days at day 28 (MD 4.06 days; 95% CI 2.66–5.45; P < 0.01). Regarding adverse events, glucocorticoids use was not associated with an increased risk for nosocomial infections (RR 0.82; 95% CI 0.68–1.00; P = 0.05); however, it was associated with an increased risk of hyperglycemia (RR 1.11; 95% CI 1.01–1.24; P = 0.04). In our trial sequential analysis, the required diversity-adjusted information size (sample size = 2692 patients) was not reached, and the evidence was insufficient from the available RCTs. Conclusion Among patients with ARDS, use of glucocorticoids is associated with a significant reduction in mortality and duration of mechanical ventilation, without increased risk of hospital-acquired infections. However, based on a trial sequential analysis, these findings may be secondary to a false-positive (type I) error. Further studies are needed for a firm conclusion with guarding against possible statistical errors.
Clinical Characteristics of Sarcoidosis Patients with Self-Reported Lymphoma: A US Nationwide Registry Study
Purpose Little is known about the association between sarcoidosis and lymphoma. We aim to determine the prevalence of lymphoma in US sarcoidosis patients and compare the clinical characteristics of patients with and without lymphoma. Methods Using a national registry-based study investigating 3560 respondents to the Foundation for Sarcoidosis Research Sarcoidosis Advanced Registry for Cures Questionnaire (FSR-SARC) completed between June 2014 and August 2019, we identified patients who reported the diagnosis of lymphoma following sarcoidosis and randomly selected a computer-generated control sample of sarcoidosis patients with no reported lymphoma with a 2:1 ratio. Results Among 3560 patients with sarcoidosis, 43 (1.2%) reported developing lymphoma following their sarcoidosis diagnosis. Patients with lymphoma were more likely to be diagnosed with sarcoidosis at a younger age (median, IQR) 40 (27–50) vs 45 (34.8–56, p  =  0.017) years, were more likely to be African–Americans OR 95% CI 3.9 (1.6–9.6, p  = 0.002), and have low annual income (OR 2.7, 1.1–6.4 p  = 0.026). The sarcoidosis–lymphoma group were more likely to have salivary gland (16% vs 5%, p  = 0.026) (OR 4; 1.1–14.5) and cutaneous (46% vs 23%, p  = 0.023) (OR 2.9; 1.1–7.3) sarcoidosis. They also reported more chronic fatigue (42% vs 23%, p  = 0.029), chronic pain (37% vs 13%, p  = 0.001), and depression (42% vs 22%, p  = 0.019). Conclusion The prevalence of lymphoma reported in sarcoidosis patients is higher than the general population which further supports the possible increased risk of lymphoma in sarcoidosis. Diagnosis of sarcoidosis at a younger age, African–American race, cutaneous, and salivary glands sarcoidosis were associated with lymphoma. Sarcoidosis patients who developed lymphoma reported higher disease burden and more non-organ-specific manifestations.
Effect of Obesity on Mortality in Pulmonary Hypertension—A Systematic Review and Meta-Analysis
Obesity is reported to have a protective effect on mortality in pulmonary hypertension (PH), a phenomenon known as obesity paradox. However, the data are conflicting, with some studies showing decreased mortality while other studies found no effect of obesity on mortality. Therefore, we performed a systematic review and meta-analysis to examine whether there is an association between obesity and mortality in PH. Only patients with PH diagnosed by right heart catheterization were included. We also performed a sub-group analysis of subjects with pre-capillary PH only. A total of six studies met the inclusion criteria, with a sample size of 13,987 patients. Obese subjects had lower mortality compared to non-obese subjects in the combined pre- and post-capillary PH group (hazard ratio 0.79, 95% CI 0.66–0.95, p = 0.01). While obesity was associated with reduction in mortality in the pre-capillary PH group (hazard ratio 0.77, 95% CI 0.60 to 0.98, p = 0.03), this was not uniform across all studies.
Effect of oxygenation modalities among patients with postoperative respiratory failure: a pairwise and network meta-analysis of randomized controlled trials
Background Postoperative respiratory failure is associated with increased perioperative complications. Our aim is to compare outcomes between non-invasive ventilation (NIV), high-flow nasal cannula (HFNC), and standard oxygen in patients at high-risk for or with established postoperative respiratory failure. Methods Electronic databases including PubMed, Embase, and the Cochrane Library were reviewed from inception to September 2019. We included only randomized controlled trials (RCTs) that compared NIV, HFNC, and standard oxygen in patients at high risk for or with established postoperative respiratory failure. We performed a Bayesian network meta-analysis to calculate the odds ratio (OR) and Bayesian 95% credible intervals (CrIs). Results Nine RCTs representing 1865 patients were included (the mean age was 61.6 ± 10.2 and 64.4% were males). In comparison with standard oxygen, NIV was associated with a significant reduction in intubation rate (OR 0.23; 95% Cr.I. 0.10–0.46), mortality (OR 0.45; 95% Cr.I. 0.27–0.71), and intensive care unit (ICU)-acquired infections (OR 0.43, 95% Cr.I. 0.25–0.70). Compared to standard oxygen, HFNC was associated with a significant reduction in intubation rate (OR 0.28, 95% Cr.I. 0.08–0.76) and ICU-acquired infections (OR 0.41; 95% Cr.I. 0.20–0.80), but not mortality (OR 0.58; 95% Cr.I. 0.26–1.22). There were no significant differences between HFNC and NIV regarding different outcomes. In a subgroup analysis, we observed a mortality benefit with NIV over standard oxygen in patients undergoing cardiothoracic surgeries but not in abdominal surgeries. Furthermore, in comparison with standard oxygen, NIV and HFNC were associated with lower intubation rates following cardiothoracic surgeries while only NIV reduced the intubation rates following abdominal surgeries. Conclusions Among patients with post-operative respiratory failure, HFNC and NIV were associated with significantly reduced rates of intubation and ICU-acquired infections compared with standard oxygen. Moreover, NIV was associated with reduced mortality in comparison with standard oxygen.
Primary adrenal Hodgkin lymphoma
Key Clinical Message A 75‐year‐old man with a left adrenal mass found on CT scan showed Hodgkin disease on biopsy. Bone marrow biopsy was normal. This is the fourth case in the literature of primary adrenal Hodgkin lymphoma. Multiple chemotherapy lines were given, and the patient years later are alive and in progression of disease.

The role of vitamin D supplementation for primary prevention of cancer: meta-analysis of randomized controlled trials
Background: In the USA cancer is the second leading cause of mortality, as such, primary prevention of cancer is a major public health concern. Vitamin D supplementation has been studied as a primary prevention method for multiple diseases including cardiovascular disease, osteoporosis, diabetes mellitus and cancer. The role of Vitamin D as primary prevention of cancer is still controversial. With fast emergence of large randomized controlled trials (RCTs) in that regards, we aimed to evaluate the efficacy of Vitamin D supplementation as primary prophylaxis for cancer. Methods: A comprehensive electronic database search was conducted for all RCTs where comparison of Vitamin D supplementation versus placebo for the prevention of any type of disease with at least 3 years of Vitamin D supplementation was used and where cancer incidence or mortality was reported. The primary outcome was cancer-related mortality and cancer incidence. We calculated risk ratios (RRs) and 95% confidence intervals (CIs) using a random-effects model at the longest follow-up. Results: We included 10 RCTs with 79,055 total patients, mean age of 68.07 years, a female percentage of 78.02% and a minimum follow-up of 4 years and more. Vitamin D was associated with significant reduction of cancer-related mortality compared with placebo (RR 0.87; 95% CI: 0.79-0.96; P = 0.05: I 2 = 0%). Compared with placebo, Vitamin D was not associated with significant reduction of cancer incidence (RR: 0.96; 95% CI: 0.86-1.07; P = 0.46; I 2 = 31%). Conclusion: With inclusion of studies, which did not primarily examine vitamin D for the purpose of preventing cancer or reducing cancer mortality our meta-analysis highlights that the use of vitamin D supplementation for primary prevention of cancer is encouraged as it does possibly decrease cancer-related mortality once cancer is diagnosed; however, it has no role or effect on cancer incidence.
Ibrutinib-induced cardiomyopathy
The use of ibrutinib for the treatment of chronic lymphocytic leukemia (CLL) and other hematologic malignancies is blooming. Atrial fibrillation is a known side effect of ibrutinib but cardiomyopathy was not reported previously. We present an 88-year-old man with CLL who was admitted to the hospital with new-onset atrial fibrillation and symptomatic systolic congestive heart failure one month after ibrutinib initiation. Although ibrutinib was discontinued, the patient continues to have a low ejection fraction four months after discontinuation. Ischemic heart disease was ruled out with normal cardiac catheterization. This case highlights a possible new side effect of ibrutinib that needs to be monitored while patients receive this medication.
