Intensive Care and Organ Support Related Mortality in Patients With COVID-19: A Systematic Review and Meta-Analysis.

To perform a systematic review and meta-analysis to generate estimates of mortality in patients with COVID-19 that required hospitalization, ICU admission, and organ support. DATA SOURCES: A systematic search of PubMed, Embase, and the Cochrane databases was conducted up to December 31, 2021. STUDY SELECTION: Previously peer-reviewed observational studies that reported ICU, mechanical ventilation (MV), renal replacement therapy (RRT) or extracorporeal membrane oxygenation (ECMO)-related mortality among greater than or equal to 100 individual patients. DATA EXTRACTION: Random-effects meta-analysis was used to generate pooled estimates of case fatality rates (CFRs) for in-hospital, ICU, MV, RRT, and ECMO-related mortality. ICU-related mortality was additionally analyzed by the study country of origin. Sensitivity analyses of CFR were assessed based on completeness of follow-up data, by year, and when only studies judged to be of high quality were included. DATA SYNTHESIS: One hundred fifty-seven studies evaluating 948,309 patients were included. The CFR for in-hospital mortality, ICU mortality, MV, RRT, and ECMO were 25.9% (95% CI: 24.0-27.8%), 37.3% (95% CI: 34.6-40.1%), 51.6% (95% CI: 46.1-57.0%), 66.1% (95% CI: 59.7-72.2%), and 58.0% (95% CI: 46.9-68.9%), respectively. MV (52.7%, 95% CI: 47.5-58.0% vs 31.3%, 95% CI: 16.1-48.9%; p = 0.023) and RRT-related mortality (66.7%, 95% CI: 60.1-73.0% vs 50.3%, 95% CI: 42.4-58.2%; p = 0.003) decreased from 2020 to 2021. CONCLUSIONS: We present updated estimates of CFR for patients hospitalized and requiring intensive care for the management of COVID-19. Although mortality remain high and varies considerably worldwide, we found the CFR in patients supported with MV significantly improved since 2020.

Cancer screening educational interventions in rural and farmworker communities: a systematic literature review.

OBJECTIVES: Men and women living in rural communities of the United States (US) are less likely than those in urban or suburban communities to be up to date with cancer screenings. Delayed screening contributes to later stage at diagnosis and higher cancer mortality for individuals living in rural areas. These effects may be compounded in some rural subpopulations (e.g. migrant and seasonal farmworkers). This systematic review examines educational interventions aimed at increasing colorectal, breast, prostate, oral, and/or cervical cancer screening in the rural US, with special consideration for the farmworker subpopulation. DESIGN: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, our systematic literature review employed the following databases: Ovid MEDLINE, CINAHL Complete, Embase, and Web of Science. Search terms included, but were not limited to 'rural,' 'cancer screening,' 'farmworker,' and 'cancer prevention.' Eligible studies featured an educational intervention implemented in agricultural or rural US settings with a cancer screening behavioral outcome, male and/or female participants, and were published in English between 2002 and 2020. Article screening and data extraction were conducted by two independent reviewers. RESULTS: Twenty-six articles were eligible. Of the six studies focused on the farmworker population (n=2,732), 61.75% of participants reported Hispanic ethnicity. Of the sixteen studies on unspecified rural communities reporting participant race/ethnicity (n=10,442), 39.29% reported Black/African American race. Efficacious interventions included culturally-targeted educational materials, lay health advisors (LHAs), and components that addressed practical barriers (e.g. financial or logistical). CONCLUSION: Results demonstrate the value of LHAs and targeted education to increase screening for multiple cancer types in rural communities. Prospective research should incorporate and facilitate access to screening and provider-level and/or organizational-level interventions to increase overall impact.

Perioperative use of the imacor hemodynamic transesophageal echocardiography probe in cardiac surgery patients: initial experience.

Echocardiography is the standard to assess heart function although obtaining transesophageal echocardiography (TEE) on an emergent basis may be limited by its availability. A transoral miniaturized hemodynamic TEE (hTEE) probe (ImaCor Inc.) was developed to provide direct visualization of the heart, and we hypothesized that the probe could provide hemodynamic information useful for patient management. Data from 2011 to 2012 was retrospectively collected. Four hundred ninety patients were treated in the cardiovascular intensive care unit of which 61 underwent hTEE monitoring and were divided into three groups: patients on extracorporeal membrane oxygenation (ECMO) (n = 25), ventricular assist device (VAD) (n = 6), and others (n = 30). Patient charts were reviewed to investigate the indications for the use of hTEE, findings, and the interventions performed. The indications for probe insertion were hemodynamic instability (n = 32), ECMO weaning (n = 10), VAD alarm (n = 1), tamponade (n = 14), pulmonary embolism (n = 2), and intra-aortic balloon pump wean (n = 2). In all 61 cases, we were successfully able to diagnose and treat the etiology of instability based on the hTEE findings. Utilization of the hTEE probe successfully diagnosed and aided therapy in all patients with hemodynamic instability refractory to initial therapy and provides a valuable tool to aid clinicians in the management of postoperative hemodynamics.

Intraoperative pancreatoscopy: a valuable tool for pancreatic surgeons?

Effective treatment of pancreatic pathology relies on both preoperative and intraoperative decision making. Traditionally, the use of preoperative imaging and endoscopic modalities, in combination with intraoperative findings and pathologic evaluation, has guided the surgeons to perform the correct operative procedure. We hypothesize that the intraoperative use of pancreatoscopy (fiberoptic endoscopy of the pancreatic duct) is a valuable adjunct in selected cases to facilitate the performance of the appropriate definitive surgical treatment. We queried our IRB-approved, prospectively maintained the pancreatic surgery database identifying the uses of intraoperative pancreatoscopy in all pancreatic resections at our institution from 2005-2012. Operative notes, pathology reports, and perioperative outcomes were evaluated. During the study period, 1,016 pancreatic resections were performed at our institution. Twenty-three cases during this period included the use of intraoperative pancreatoscopy. Eighteen (78 %) of these operations were performed for presumed main duct intraductal papillary mucinous neoplasm. In five cases (22 %), the surgical resection was extended secondary to the intraoperative pancreatoscopy findings. Appropriate surgical treatment of the pancreatic lesions can be challenging in the face of preoperative imaging limitations. The selective use of intraoperative fiberoptic endoscopy to evaluate the pancreatic duct appears to help to enable the surgeon to better perform the appropriate resection and optimal treatment.

Altered drainage patterns in patients with melanoma and previous axillary dissection.

The incidence of melanoma is increasing rapidly in the United States. Sentinel lymph node biopsy is an important diagnostic tool in the treatment and staging of melanoma. However, many patients with melanoma will have had lymph node surgery for previous melanoma or breast cancer. We set out to examine alterations in drainage patterns in patients with previous axillary dissection for breast cancer. We reviewed four patients with truncal and/or extremity melanomas and examined their lymphoscintigraphy and drainage patterns. Three patients with truncal melanoma mapped to cervical lymph nodes and a fourth patient with an arm melanoma mapped to her previously dissected axilla. Sentinel lymph node mapping is still an important adjunct in patients with melanoma despite previous axillary dissection.

Lung hernia after video-assisted thoracoscopic lobectomy.

Lung hernias are rare and are most commonly secondary to blunt or penetrating trauma. Few cases have been reported after video-assisted thoracoscopic surgery and only one case after video-assisted thoracoscopic surgery lobectomy. We report a case of lung hernia after video-assisted, thoracoscopic, right upper lobectomy. The hernia was demonstrated by computerized tomography and repaired by minimally invasive techniques. We believe that the combination of removal of a large lung specimen and the presence of emphysema may predispose to lung herniation after thoracoscopic lobectomy. Thoracic surgeons should be aware of this possible complication.

Maternal mixed connective tissue disease and offspring with chondrodysplasia punctata.

OBJECTIVES: To describe the case of a mother with mixed connective tissue disease (MCTD) whose male and female offspring from 2 successive pregnancies had chondrodysplasia punctata (CDP) in the absence of identifiable biochemical or genetic abnormalities or teratogen exposure. METHODS: Description of a male and female offspring from a mother with MCTD harboring high-titer anti-ribonucleoprotein (RNP) antibodies. Maternal autoantibody assays were performed employing quantitative multiplex suspension arrays and flow cytometry, and autoantibody titer and pattern were determined by indirect immunofluorescence. Assays of phytanic acid, plasmalogen, and very long-chain fatty acids were performed employing commercially available reagents. Chromosomal analysis was performed on both offspring employing standard cytogenetic analysis. Review of the relevant literature was performed (PubMed search 1966 through July 2008). RESULTS: Two children with CDP born to a mother with MCTD who harbored anti-RNP autoantibodies at high titer are described. Genetic and chromosomal studies and biochemical analysis of peroxisome function and very long-chain fatty acids excluded known biochemical or genetic defects or mutations as the cause of CDP in these children. Furthermore, detailed review of the clinical history failed to disclose any evidence of maternal teratogen exposure during the 2 pregnancies. CONCLUSIONS: Maternal MCTD is the most likely explanation for the occurrence of CDP in the 2 children reported here. Review of previously published cases of CDP associated with autoimmune disease suggests that placental crossing of maternal autoantibodies during pregnancy specifically affecting the normal development of fetal growth plates is responsible for CDP in the offspring in these cases.

Expanding the phenotype of SPONASTRIME dysplasia to include short dental roots, hypogammaglobulinemia, and cataracts.

SPONASTRIME dysplasia (SD) is an autosomal recessive skeletal dysplasia of the spondyloepimetaphyseal dysplasia (SEMD) type. The name was derived from "spondylar and nasal alterations with striated metaphyses" [Fanconi et al. 1983; Helv Paediat Acta 38: 267-280]. We follow two previously reported patients with SD [Patients 3, 4 in Langer et al. 1996; Am J Med Genet 63: 20-27]. Since the original publication, additional findings were identified in these patients.
