RESUMO
Falls are a major public health problem, occurring in more than 27% of adults 65 years and older and costing the U.S. health care system tens of billions of dollars each year. The most common risk factors are prior falls, balance disorders, fear of falling, and dementia. Regular physical activity reduces fall risk. Identifying injuries is the first step in evaluating older adults who have fallen. The patient's history may be inaccurate if they have cognitive impairment, and the physical examination can result in false-negative findings. If injury status cannot be determined and suspicion for injury remains high, clinicians can consider whole-body computed tomography (i.e., pan-scan) to evaluate the head, cervical spine, chest, abdomen, and pelvis. After addressing injuries, the next steps are to identify the cause of the fall and implement measures to reduce future fall risk. The Centers for Disease Control and Prevention has developed an easy-to-use tool to screen for and reduce fall risk, known as STEADI (Stopping Elderly Accidents, Deaths, and Injuries). An affirmative answer to any of the three STEADI screening questions indicates further evaluation with a timed up and go test, 30-second chair stand test, and four-stage balance test. If results of these tests are abnormal, multicomponent interventions are indicated to reduce future fall risk. These components include evaluating environmental and home safety factors and optimizing care of chronic medical conditions, such as diabetes mellitus, hypertension, osteoporosis, pain, urinary urgency and incontinence, and depression. Polypharmacy and drugs that increase risk of falls should be avoided, when possible. Optimization of vision and hearing correction, podiatry care, and appropriate use of ambulation devices are also important.

BACKGROUND: The Children's Oncology Group (COG) adopted cisplatin, 5-flourouracil, and vincristine (C5V) as standard therapy after the INT-0098 legacy study showed statistically equivalent survival but less toxicity in comparison with cisplatin and doxorubicin. Subsequent experience demonstrated doxorubicin to be effective in patients with recurrent disease after C5V, and this suggested that it could be incorporated to intensify therapy for patients with advanced disease. METHODS: In this nonrandomized, phase 3 COG trial, the primary aim was to explore the feasibility and toxicity of a novel therapeutic cisplatin, 5-flourouracil, vincristine, and doxorubicin (C5VD) regimen with the addition of doxorubicin to C5V for patients considered to be at intermediate risk. Patients were eligible if they had unresectable, nonmetastatic disease. Patients with a complete resection at diagnosis and local pathologic evidence of small cell undifferentiated histology were also eligible for an assessment of feasibility. RESULTS: One hundred two evaluable patients enrolled between September 14, 2009, and March 12, 2012. Delivery of C5VD was feasible and tolerable: the mean percentages of the target doses delivered were 96% (95% CI, 94%-97%) for cisplatin, 96% (95% CI, 94%-97%) for 5-fluorouracil, 95% (95% CI, 93%-97%) for doxorubicin, and 90% (95% CI, 87%-93%) for vincristine. Toxicity was within expectations, with death as a first event in 1 patient. The most common adverse events were febrile neutropenia (n = 55 [54%]), infection (n = 48 [47%]), mucositis (n = 31 [30%]), hypokalemia (n = 39 [38%]), and elevated aspartate aminotransferase (n = 28 [27%]). The 5-year event-free and overall survival rates for the 93 patients who did not have complete resection at diagnosis were 88% (95% CI, 79%-93%) and 95% (95% CI, 87%-98%), respectively. CONCLUSIONS: The addition of doxorubicin to the previous standard regimen of C5V is feasible, tolerable, and efficacious, and this suggests that C5VD is a good regimen for future clinical trials.

PURPOSE: Small cell undifferentiated (SCU) histology in hepatoblastoma (HB) tumors has historically been associated with a poor prognosis. Tumors from patients enrolled on Children's Oncology Group (COG) study AHEP0731 underwent institutional and central pathologic review for identification of SCU histology. PATIENTS AND METHODS: Patients with SCU histology identified at the local treating institution who had otherwise low-risk tumors were upstaged to the intermediate-risk treatment stratum, whereas those only identified by retrospective central review were treated per the local institution as low-risk. Patients with otherwise intermediate- or high-risk tumors remained in that treatment stratum, respectively. Central review was to be performed for all tissue samples obtained at any time point. Treatment was per local review, whereas analysis of outcome was based on central review. RESULTS: Thirty-five patients had some elements (1%-25%) of SCU identified on central review of diagnostic specimens. All but two patient tissue sample retained nuclear INI1 expression. The presence of SCU histology did not correlate with age, alpha-fetoprotein level at diagnosis, or sex. The presence of SCU did not affect event-free survival (EFS). EFS at 5 years for patients with low-risk, intermediate-risk, and high-risk with SCU HB was 86% (95% CI, 33 to 98), 81% (95% CI, 57 to 92), and 29% (95% CI, 4 to 61), respectively, compared with EFS at 5 years for patients without SCU enrolled with low-risk, intermediate-risk, and high-risk of 87% (95% CI, 72 to 95), 88% (95% CI, 79 to 94), and 55% (95% CI, 32 to 74; P = .17), respectively. CONCLUSION: The presence of SCU histology in HB does not appear to adversely affect outcome. Future studies should be able to treat patients with SCU HB according to risk stratification without regard to the presence of SCU histology.

BACKGROUND: Hepatoblastoma (HB) requires surgical resection for cure, but only 20-30% of patients have resectable disease at diagnosis. Patients who undergo partial hepatectomy at diagnosis have historically received 4-6 cycles of adjuvant chemotherapy; however, those with 100% well-differentiated fetal histology (WDF) have been observed to have excellent outcomes when treated with surgery alone. PATIENTS AND METHODS: Patients on the Children's Oncology Group non randomized, multicenter phase III study, AHEP0731, were stratified based on Evan's stage, tumor histology, and serum alpha-fetoprotein level at diagnosis. Patients were eligible for the very low risk stratum of surgery and observation if they had a complete resection at diagnosis and rapid central histologic review demonstrated HB with 100% WDF histology. RESULTS: A total of 8 eligible patients were enrolled on study between September 14, 2009 and May 28, 2014. Outcome current to 06/30/2020 was used in this analysis. The median age at enrollment was 22.5 months (range: 8-84 months) and the median AFP at enrollment was 714 ng/ml (range: 18-77,747 ng/mL). With a median follow-up of 6.6 years (range: 3.6-9.8 years), the 5-year event-free (EFS) and overall survival (OS) were both 100%. CONCLUSION: This report supports that HB with 100% WDF histology completely resected at diagnosis is curable with surgery only. The development of evidence-based surgical guidelines utilizing criteria based on PRETEXT group, vascular involvement (annotation factors), tumor-specific histology and corresponding biology will be crucial for optimizing which patients are candidates for resection at diagnosis followed by observation. LEVEL OF EVIDENCE: Prognosis study, Level I evidence.

Situated in southeastern Sierra Leone, Kenema Government Hospital (KGH) maintains one of the world's only Lassa fever isolation wards and was a strategic Ebola virus disease (EVD) treatment facility during the 2014 EVD outbreak. Since 2006, the Viral Hemorrhagic Fever Consortium (VHFC) has carried out research activities at KGH, capturing clinical and laboratory data for suspected cases of Lassa fever. Here we describe the approach, progress, and challenges in designing and maintaining a data capture and management system (DCMS) at KGH to assist infectious disease researchers in building and sustaining DCMS in low-resource environments. Results on screening patterns and case-fatality rates are provided to illustrate the context and scope of the DCMS covered in this study. A medical records system and DCMS was designed and implemented between 2010 and 2016 linking historical and prospective Lassa fever data sources across KGH Lassa fever units and its peripheral health units. Data were captured using a case report form (CRF) system, enzyme-linked immunosorbent assay (ELISA) plate readers, polymerase chain reaction (PCR) machines, blood chemistry analyzers, and data auditing procedures. Between 2008 and 2016, blood samples for 4,229 suspected Lassa fever cases were screened at KGH, ranging from 219 samples in 2008 to a peak of 760 samples in 2011. Lassa fever case-fatality rates before and following the Ebola outbreak were 65.5% (148/226) and 89.5% (17/19), respectively, suggesting that fewer, but more seriously ill subjects with Lassa fever presented to KGH following the 2014 EVD outbreak (p = .040). DCMS challenges included weak specificity of the Lassa fever suspected case definition, limited capture of patient survival outcome data, internet costs, lapses in internet connectivity, low bandwidth, equipment and software maintenance, lack of computer teaching laboratories, and workload fluctuations due to variable screening activity. DCMS are the backbone of international research efforts and additional literature is needed on the topic for establishing benchmarks and driving goal-based approaches for its advancement in developing countries.
