Characteristics and outcomes of hospitalised patients with vertebral fragility fractures: a systematic review

Background: The complex management for patients presenting to hospital with vertebral fragility fractures provides justification for the development of specific services for them. A systematic review was undertaken to determine the incidence of hospital admission, patient characteristics, and health outcomes of vertebral fragility fracture patients to inform the development of such a service. Methods: Non-randomised studies of vertebral fragility fracture in hospital were included. Searches were conducted using electronic databases and citation searching of the included papers. Results: 19 studies were included. The incidence of hospital admission varied from 2.8-19.3 per 10,000/year. The average patient age was 81 years, the majority having presented with a fall. A diagnosis of osteoporosis or previous fragility fracture was reported in around one third of patients. Most patients (75% men and 78% women) had five or more co-pathologies. Most patients were managed non-operatively with a median hospital length of stay of 10 days. One third of patients were started on osteoporosis treatment. Inpatient and one year mortality was between 0.9-3.5%, and 20–25% respectively: between 34-50% were discharged from hospital to a care facility. Many patients were more dependent with activities of daily living on discharge compared to their pre-admission level. Older age and increasing comorbidities was associated with longer hospital stay and higher mortality. Conclusion: These findings indicate that specific hospital services for patients with vertebral fragility fractures should take into consideration local hospitalisation rates for the condition, and should be multifaceted - providing access to diagnostic, therapeutic, surgical and rehabilitation interventions

Clinical Relevance and Discriminatory Value of Elevated Liver Aminotransferase Levels for Dengue Severity

Dengue is a global public health problem, as the incidence of the disease has reached hyperendemic proportions in recent decades. Infection with dengue can cause acute, febrile illness or severe disease, which can lead to plasma leakage, bleeding, and organ impairment. One of the most prominent clinical characteristics of dengue patients is increased aspartate and alanine aminotransferase liver enzyme levels. The significance of this is uncertain, as it is transient in the majority of cases, and most patients recover uneventfully without liver damage. In this study, we characterized this phenomenon in the context of dengue severity and found that, although liver enzyme levels increased concurrently with dengue severity, they could not sufficiently discriminate between dengue fever and dengue hemorrhagic fever or between non-severe and severe dengue. Therefore clinicians may need to use other parameters to distinguish dengue severity in patients during early illness

Unipolar versus bipolar hemiarthroplasty for displaced femoral neck fractures: A pooled analysis of 30,250 participants data

PURPOSE: To assess the clinical outcomes of unipolar versus bipolar hemiarthroplasty for displaced intracapsular femoral neck fractures in older patients and to report whether bipolar implants yield better long-term functional results. METHODS: We searched PubMed, Scopus, EBSCO, and Cochrane Library for relevant randomized clinical trials (RCTs) and observational studies, comparing unipolar and bipolar hemiarthroplasty. Data were extracted from eligible studies and pooled as relative risk (RR) or mean difference (MD) with corresponding 95% confidence intervals (CI) using RevMan software for Windows. RESULTS: A total of 30 studies were included (13 RCTs and 17 observational studies). Analyses included 30,250 patients with a mean age of 79 years and mean follow-up time of 24.6 months. The overall pooled estimates showed that bipolar was superior to unipolar hemiarthroplasty in terms of hip function, range of motion and reoperation rate, but at the expense of longer operative time. In the longer term the unipolar group had higher rates of acetabular erosion compared to the bipolar group. There was no significant difference in terms of hip pain, implant related complications, intraoperative blood loss, mortality, six-minute walk times, medical outcomes, and hospital stay and subsequently cost. CONCLUSIONS: Bipolar hemiarthroplasty is associated with better range of motion, lower rates of acetabular erosion and lower reoperation rates compared to the unipolar hemiarthroplasty but at the expense of longer operative time. Both were similar in terms of mortality, and surgical or medical outcomes. Future large studies are recommended to compare both methods regarding the quality of life

Understanding which factors contribute to a more advanced stage at diagnosis is vital to improving overall survival. Comorbidity, race, and age are known to impact receipt of cancer therapy and survival, but the relationship of these factors to stage at diagnosis of CRC is less clear. The objective of this study is to investigate how comorbidity, race and age influence stage of CRC diagnosis. Methods : Two distinct healthcare populations in the United States (US) were retrospectively studied. Using the Cancer Care Outcomes Research and Surveillance Consortium database, we identified CRC patients treated at 15 Veterans Administration (VA) hospitals from 2003–2007. We assessed metastatic CRC patients treated from 2003–2006 at 10 non-VA, fee-for-service (FFS) practices. Stage at diagnosis was dichotomized (non-metastatic, metastatic). Race was dichotomized (white, non-white). Charlson comorbidity index and age at diagnosis were calculated. Associations between stage, comorbidity, race, and age were determined by logistic regression. Results : 342 VA and 340 FFS patients were included. Populations differed by the proportion of patients with metastatic CRC at diagnosis (VA 27% and FFS 77%) reflecting differences in eligibility criteria for inclusion. VA patients were mean (standard deviation; SD) age 67 (11), Charlson index 2.0 (1.0), and were 63% white. FFS patients were mean age 61 (13), Charlson index 1.6 (1.0), and were 73% white. In the VA cohort, higher comorbidity was associated with earlier stage at diagnosis after adjusting for age and race (odds ratio (OR) 0.76, 95% confidence interval (CI) 0.58–1.00; p = 0.045); no such significant relationship was identified in the FFS cohort (OR 1.09, 95% CI 0.82–1.44; p = 0.57). In both cohorts, no association was found between stage at diagnosis and either age or race. Conclusion : Higher comorbidity may lead to earlier stage of CRC diagnosis. Multiple factors, perhaps including increased interactions with the healthcare system due to comorbidity, might contribute to this finding. Such increased interactions are seen among patients within a healthcare system like the VA system in the US versus sporadic interactions which may be seen with FFS healthcare

A Prospective Observational Study of Complications in 140 Sialendoscopies

Objectives. To evaluate the incidence and nature of complications associated with diagnostic and interventional sialendoscopies and to report intervention failures in a prospective setup. Study Design. Prospective observational study. Setting. Academic tertiary care university hospital. Subjects and Methods. Patients who underwent diagnostic or interventional sialendoscopy between October 2015 and December 2016 were prospectively enrolled. Patient data, operation-related factors, treatment failures, and complications were recorded into a database and analyzed. Results. A total of 140 sialendoscopies were attempted or performed on 118 patients; 67 (48%) were for a parotid gland and 73 (52%) for a submandibular gland. The sialendoscopy was interventional in 81 cases (58%), diagnostic in 56 (40%), and not possible to perform in 3 (2.1%). A total of 21 complications were registered for 21 sialendoscopies (15%) and 21 patients (18%). The most common complication was infection, in 9 cases (6.4%). Other observed complications were salivary duct perforation (4 cases), prolonged glandular swelling (3 cases), transient lingual nerve analgesia (2 cases), basket entrapment (2 cases), and transient weakness in the marginal branch of the facial nerve (1 case). All complications were related to interventional procedures or papilla dilatation. Failure to treat occurred in 21 (15%) sialendoscopies: sialendoscopy itself was unsuccessful in 3 cases, and an intended intervention failed in 18 cases. Conclusion. Complications in sialendoscopy are usually related to interventional procedures. The complications are mainly minor and temporary but lead to additional follow-up visits, further treatments, and sometimes hospitalization. Sialendoscopic procedures are safe but not free of complications.Peer reviewe
