Hip fractures in elderly people:Surgery or no surgery? A systematic review and meta-analysis
Iintroduction:Â Increasing numbers of patients with hip fractures also have advanced comorbidities. A majority are treated surgically. However, a significantly increasing percentage of medically unfit patients with unacceptably high risk of perioperative death are treated nonoperatively. Important questions about patients' prefracture quality of life (QOL) and future perspectives should be asked before considering different treatment options to assess what kind of treatment is advisable in frail elderly high-risk patients with a hip fracture. Objective:Â The aim of this review was to provide an overview of differences in mortality, health-related QOL [(HR)QOL], functional outcome, and costs between nonoperative management (NOM) and operative management (OM) of hip fractures in patients above 65 years. Methods:Â A systematic literature search was performed in EMBASE, OvidSP, PubMed, Cochrane Central, and Web of Science for observational studies and trials. Observational studies and randomized controlled trials comparing NOM with OM in hip fracture patients were selected. The methodological quality of the selected studies was assessed according to the Methodological Index for Nonrandomized Studies (MINORS) or Furlan checklist. Results:Â Seven observational studies were included with a total of 1189 patients, of whom 242 (20.3%) were treated conservatively. The methodological quality of the studies was moderate (mean: 14.7, standard deviation [SD]: 1.5). The 30-day and 1-year mortalities were higher in the nonoperative group (odds ratio [OR]: 3.95, 95% confidence interval [CI]: 1.43-10.96; OR: 3.84, 95% CI: 1.57-9.41). None of the included studies compared QOL, functional outcome, or health-care costs between the 2 groups. Conclusion:Â This systematic review and meta-analysis demonstrated that only a few studies with small number of patients comparing NOM with OM were published. A significantly higher 30-day and 1-year mortality was revealed in nonoperatively treated hip fracture patients. No data were found examining (HR)QOL and costs. Further work is needed to enable shared decision-making and to initiate NOM in frail elderly patients with advanced comorbidity and limited life expectancy

Immune Phenotype and Function of Natural Killer and T Cells in Chronic Hepatitis C Patients Who Received a Single Dose of Anti-MicroRNA-122, RG-101
MicroRNAâ122 is an important host factor for the hepatitis C virus (HCV). Treatment with RGâ101, an Nâacetylgalactosamineâconjugated antiâmicroRNAâ122 oligonucleotide, resulted in a significant viral load reduction in patients with chronic HCV infection. Here, we analyzed the effects of RGâ101 therapy on antiviral immunity. Thirtyâtwo chronic HCV patients infected with HCV genotypes 1, 3, and 4 received a single subcutaneous administration of RGâ101 at 2 mg/kg (n = 14) or 4 mg/kg (n = 14) or received a placebo (n = 2/dosing group). Plasma and peripheral blood mononuclear cells were collected at multiple time points, and comprehensive immunological analyses were performed. Following RGâ101 administration, HCV RNA declined in all patients (mean decline at week 2, 3.27 log10 IU/mL). At week 8 HCV RNA was undetectable in 15/28 patients. Plasma interferonâÎłâinduced protein 10 (IPâ10) levels declined significantly upon dosing with RGâ101. Furthermore, the frequency of natural killer (NK) cells increased, the proportion of NK cells expressing activating receptors normalized, and NK cell interferonâÎł production decreased after RGâ101 dosing. Functional HCVâspecific interferonâÎł Tâcell responses did not significantly change in patients who had undetectable HCV RNA levels by week 8 postâRGâ101 injection. No increase in the magnitude of HCVâspecific Tâcell responses was observed at later time points, including 3 patients who were HCV RNAânegative 76 weeks postdosing. Conclusion: Dosing with RGâ101 is associated with a restoration of NKâcell proportions and a decrease of NK cells expressing activation receptors; however, the magnitude and functionality of ex vivo HCVâspecific Tâcell responses did not increase following RGâ101 injection, suggesting that NK cells, but not HCV adaptive immunity, may contribute to HCV viral control following RGâ101 therapy
Height and timing of growth spurt during puberty in young people living with vertically acquired HIV in Europe and Thailand.
OBJECTIVE: The aim of this study was to describe growth during puberty in young people with vertically acquired HIV. DESIGN: Pooled data from 12 paediatric HIV cohorts in Europe and Thailand. METHODS: One thousand and ninety-four children initiating a nonnucleoside reverse transcriptase inhibitor or boosted protease inhibitor based regimen aged 1-10 years were included. Super Imposition by Translation And Rotation (SITAR) models described growth from age 8 years using three parameters (average height, timing and shape of the growth spurt), dependent on age and height-for-age z-score (HAZ) (WHO references) at antiretroviral therapy (ART) initiation. Multivariate regression explored characteristics associated with these three parameters. RESULTS: At ART initiation, median age and HAZ was 6.4 [interquartile range (IQR): 2.8, 9.0] years and -1.2 (IQR: -2.3 to -0.2), respectively. Median follow-up was 9.1 (IQR: 6.9, 11.4) years. In girls, older age and lower HAZ at ART initiation were independently associated with a growth spurt which occurred 0.41 (95% confidence interval 0.20-0.62) years later in children starting ART age 6 to 10 years compared with 1 to 2 years and 1.50 (1.21-1.78) years later in those starting with HAZ less than -3 compared with HAZ at least -1. Later growth spurts in girls resulted in continued height growth into later adolescence. In boys starting ART with HAZ less than -1, growth spurts were later in children starting ART in the oldest age group, but for HAZ at least -1, there was no association with age. Girls and boys who initiated ART with HAZ at least -1 maintained a similar height to the WHO reference mean. CONCLUSION: Stunting at ART initiation was associated with later growth spurts in girls. Children with HAZ at least -1 at ART initiation grew in height at the level expected in HIV negative children of a comparable age
Patch: platelet transfusion in cerebral haemorrhage: study protocol for a multicentre, randomised, controlled trial
<p>Abstract</p> <p>Background</p> <p>Patients suffering from intracerebral haemorrhage have a poor prognosis, especially if they are using antiplatelet therapy. Currently, no effective acute treatment option for intracerebral haemorrhage exists. Limiting the early growth of intracerebral haemorrhage volume which continues the first hours after admission seems a promising strategy. Because intracerebral haemorrhage patients who are on antiplatelet therapy have been shown to be particularly at risk of early haematoma growth, platelet transfusion may have a beneficial effect.</p> <p>Methods/Design</p> <p>The primary objective is to investigate whether platelet transfusion improves outcome in intracerebral haemorrhage patients who are on antiplatelet treatment. The PATCH study is a prospective, randomised, multi-centre study with open treatment and blind endpoint evaluation. Patients will be randomised to receive platelet transfusion within six hours or standard care. The primary endpoint is functional health after three months. The main secondary endpoints are safety of platelet transfusion and the occurrence of haematoma growth. To detect an absolute poor outcome reduction of 20%, a total of 190 patients will be included.</p> <p>Discussion</p> <p>To our knowledge this is the first randomised controlled trial of platelet transfusion for an acute haemorrhagic disease.</p> <p>Trial registration</p> <p>The Netherlands National Trial Register (NTR1303)</p

Ultra-Early and Short-Term Tranexamic Acid Treatment in Patients With Good- and Poor-Grade Aneurysmal Subarachnoid Hemorrhage
The results of the ULTRA trial showed that ultra-early and short-term treatment with tranexamic acid (TXA) does not improve clinical outcome after aneurysmal subarachnoid hemorrhage (aSAH). Possibly, the lack of a beneficial effect in all patients with aSAH is masked by antagonistic effects of TXA in certain subgroups. In this post hoc subgroup analysis, we investigated the effect of TXA on clinical outcome in patients with good-grade and poor-grade aSAH
