Summary
In patients with haemophilia A, repeated occurrences of haemarthrosis and synovitis lead to limitations in range of motion (ROM) of major joints. However, the effect of limitations in joint ...ROM on health‐related quality of life (HRQOL) in these patients has not been studied previously. The aim of this study was to assess the impact of ROM limitations of 10 major joints (bilateral shoulders, elbows, hips, knees and ankles), combined with other possibly influential factors, on HRQOL in patients with haemophilia A. The ROM limitations in 13 movements and pain intensity of the 10 major joints were measured. The socio‐demographic and clinical data were recorded. Short‐Form 36 was used as the HRQOL measurement. Eighteen patients (mean age: 36.9 years) were included. Hip ROM limitations, knee ROM limitations and hip pain intensity predicted physical functioning scale (P < 0.001; adjusted R2 = 0.553). Shoulder ROM limitations and age predicted role limitation were due to emotional problems scale (P < 0.001; adjusted R2 = 0.373). Elbow ROM limitations and haemophilia severity predicted mental health scale (P = 0.001; adjusted R2 = 0.320). Hip ROM limitations predicted social functioning scale (P = 0.041; adjusted R2 = 0.091). Educational level and elbow ROM limitations predicted vitality scale (P < 0.001; adjusted R2 = 0.416). The ROM limitations of hip, knee, shoulder and elbow could be predictors for HRQOL in patients with haemophilia A. Improving ROM of major joints could be an appropriate treatment strategy to enhance HRQOL in these patients.

The MiniBooNE experiment at Fermilab reports a total excess of 638.0 ± 52.1 (stat .) ± 122.2 (syst.) electronlike events from a data sample corresponding to 18.75 × 10 20 protons-on-target in ...neutrino mode, which is a 46% increase in the data sample with respect to previously published results and 11.27 × 10 20 protons-on-target in antineutrino mode. The overall significance of the excess, 4.8σ, is limited by systematic uncertainties, assumed to be Gaussian, as the statistical significance of the excess is 12.2σ. The additional statistics allow several studies to address questions on the source of the excess. First, we provide two-dimensional plots in visible energy and the cosine of the angle of the outgoing lepton, which can provide valuable input to models for the event excess. Second, we test whether the excess may arise from photons that enter the detector from external events or photons exiting the detector from π 0 decays in two model independent ways. Beam timing information shows that almost all of the excess is in time with neutrinos that interact in the detector. The radius distribution shows that the excess is distributed throughout the volume, while tighter cuts on the fiducial volume increase the significance of the excess. The data likelihood ratio disfavors models that explain the event excess due to entering or exiting photons.

Blood loss during liver surgery is found to be correlated with central venous pressure (CVP). The aim of the current retrospective study is to find out the cutoff value of CVP and stroke volume ...variation (SVV), which may increase the risk of having intraoperative blood loss of more than 100 mL during living liver donor hepatectomies.
Twenty-seven adult living liver donors were divided into 2 groups according to whether they had intraoperative blood loss of less (G1) or more than 100 mL (G2). The mean values of the patients' CVP and SVV at the beginning of the transaction of the liver parenchyma was used as the cutoff point. Its correlation to intraoperative blood loss was evaluated using the χ2 test; P < .001 was regarded as significant.
The cutoff points of CVP and SVV were 8 mm Hg and 13% respectively. The odds ratio of having blood loss exceeding 100 mL was 91.25 (P < .001) and 0.36 (P < .001) for CVP and SVV, respectively.
CVP less than 5 mm Hg, as suggested by most authors, is not always clinical achievable. Our results show that a value of less than 8 mm Hg or SVV 13% is able to achieve a minimal blood loss of 100 mL during parenchyma transaction during a living donor hepatectomy. Measurements used to lower the CVP or increased SVV in our serial were intravenous fluids restriction and the use of a diuretic.

Abstract
Lateral wall thickness is a known predictor for postoperative stability of trochanteric femoral fractures and occurrence of secondary lateral wall fractures. Currently, the AO/OTA ...classification relies on the absolute lateral wall thickness (aLWT) to distinguish between stable A1.3 and unstable A2.1 fractures that does not take interpersonal patient differences into account. Thus, a more individualized and accurate measure would be favorable. Therefore, we proposed and validated a new patient-specific measure—the relative lateral wall thickness (rLWT)—to consider individualized measures and hypothesized its higher sensitivity and specificity compared with aLWT. First, in 146 pelvic radiographs of patients without a trochanteric femoral fracture, the symmetry of both caput-collum-diaphyseal angle (CCD) and total trochanteric thickness (TTT) was assessed to determine whether the contralateral side can be used for rLWT determination. Then, data of 202 patients were re-evaluated to compare rLWT versus previously published aLWT. Bilateral symmetry was found for both CCD and TTT (p ≥ 0.827), implying that bone morphology and geometry of the contralateral intact side could be used to calculate rLWT. Validation revealed increased accuracy of the rLWT compared with the gold standard aLWT, with increased specificity by 3.5% (Number Needed to Treat = 64 patients) and sensitivity by 1% (Number Needed to Treat = 75 patients). The novel rLWT is a more accurate and individualized predictor of secondary lateral wall fractures compared with the standard aLWT. This study established the threshold of 50.5% rLWT as a reference value for predicting fracture stability in trochanteric femoral fractures.

Aim
Low anterior resection syndrome (LARS) can affect up to 70% of all patients with rectal cancer. In the last two decades, sacral nerve stimulation (SNS) has emerged as an effective treatment for ...faecal incontinence. There is some encouraging literature on the use of SNS in patients with LARS. The purpose of this review is to provide an up to date review on the utility of SNS on LARS.
Method
A literature search was conducted using the MEDLINE, Embase and PubMed databases (January 1981–March 2019). Studies identified were appraised with standard selection criteria. Data points were extracted, and meta‐analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses.
Results
Ten studies met the inclusion criteria and were included in this study. All studies used the Cleveland Clinic Incontinence Score (CCIS), whereas the low anterior resection syndrome score (LARS score) was used in three studies. Overall median improvement in the scoring system was 67.0% (range 35.5%–88.2%) after SNS implantation. There was a significant reduction in CCIS after SNS implantation (mean difference 11.23, 95% confidence interval 9.38–13.07, Z = 11.90, P < 0.00001). The LARS score was also significantly reduced after using SNS in patients with LARS (mean difference 17.87, 95% confidence interval 10.15–25.59, Z = 4.54, P < 0.00001).
Conclusion
Use of SNS may provide symptomatic benefits for patients with LARS refractory to medical therapy. However, the current level of evidence remains limited. A large multicentre study of SNS for LARS using the validated LARS score is warranted. In addition, the cost‐effectiveness of SNS for patients with LARS needs further exploration.

A search for sub-GeV dark matter produced from collisions of the Fermilab 8 GeV Booster protons with a steel beam dump was performed by the MiniBooNE-DM Collaboration using data from 1.86 × 1020 ...protons on target in a dedicated run. The MiniBooNE detector, consisting of 818 tons of mineral oil and located 490 meters downstream of the beam dump, is sensitive to a variety of dark matter initiated scattering reactions. Three dark matter interactions are considered for this analysis: elastic scattering off nucleons, inelastic neutral pion production, and elastic scattering off electrons. Multiple data sets were used to constrain flux and systematic errors, and time-of-flight information was employed to increase sensitivity to higher dark matter masses. No excess from the background predictions was observed, and 90% confidence level limits were set on the vector portal and leptophobic dark matter models. New parameter space is excluded in the vector portal dark matter model with a dark matter mass between 5 and 50 MeV c−2 . The reduced neutrino flux allowed to test if the MiniBooNE neutrino excess scales with the production of neutrinos. No excess of neutrino oscillation events were measured ruling out models that scale solely by number of protons on target independent of beam configuration at 4.6σ.

The MiniBooNE experiment at Fermilab reports results from an analysis of ν_{e} appearance data from 12.84×10^{20} protons on target in neutrino mode, an increase of approximately a factor of 2 over ...previously reported results. A ν_{e} charged-current quasielastic event excess of 381.2±85.2 events (4.5σ) is observed in the energy range 200<E_{ν}^{QE}<1250 MeV. Combining these data with the νover ¯_{e} appearance data from 11.27×10^{20} protons on target in antineutrino mode, a total ν_{e} plus νover ¯_{e} charged-current quasielastic event excess of 460.5±99.0 events (4.7σ) is observed. If interpreted in a two-neutrino oscillation model, ν_{μ}→ν_{e}, the best oscillation fit to the excess has a probability of 21.1%, while the background-only fit has a χ^{2} probability of 6×10^{-7} relative to the best fit. The MiniBooNE data are consistent in energy and magnitude with the excess of events reported by the Liquid Scintillator Neutrino Detector (LSND), and the significance of the combined LSND and MiniBooNE excesses is 6.0σ. A two-neutrino oscillation interpretation of the data would require at least four neutrino types and indicate physics beyond the three neutrino paradigm. Although the data are fit with a two-neutrino oscillation model, other models may provide better fits to the data.
