The analgesic efficacy of transversus abdominis plane block vs. wound infiltration after inguinal and infra-umbilical hernia repairs: A systematic review and meta-analysis with trial sequential analysis.
Both transversus abdominis plane (TAP) block and wound infiltration with local anaesthetic have been used to relieve pain after inguinal or infra-umbilical hernia repair.
To determine whether TAP block or local anaesthetic infiltration is the best analgesic option after inguinal or infra-umbilical hernia repair.
Systematic review and meta-analysis with trial sequential analysis.
MEDLINE, Embase, Cochrane Central Register of Controlled Clinical Trials, Web of Science, up to June, 2020.
We retrieved randomised controlled trials comparing TAP block with wound infiltration after inguinal or infra-umbilical hernia repair. Primary outcome was rest pain score (analogue scale 0 to 10) at 2 postoperative hours. Secondary pain-related outcomes included rest pain score at 12 and 24 h, and intravenous morphine consumption at 2, 12 and 24 h. Other secondary outcomes sought were block-related complications such as rates of postoperative infection, haematoma, visceral injury and systemic toxicity of local anaesthetic.
Seven trials including 420 patients were identified. There was a significant difference in rest pain score at 2 postoperative hours in favour of TAP block compared with wound infiltration, with a mean (95% confidence interval) difference of -0.8 (-1.3 to -0.2); I2 = 85%; P = 0.01. Most secondary pain-related outcomes were also significantly improved following TAP block. No complication was reported. The overall quality of evidence was moderate.
There is moderate level evidence that TAP block provides superior analgesia compared with wound infiltration following inguinal or infra-umbilical hernia repair.

Efficacy and safety of neuraxial hydromorphone: A systematic review and meta-analysis with trial sequential analysis.
Neuraxial hydromorphone provides postoperative pain relief. However, the magnitude of this effect and the optimal dose remain unknown. The objective of this study is to clarify these uncertainties.
Systematic review and meta-analysis with trial sequential analysis.
Postoperative recovery area and ward, up to 24 h.
Any patient undergoing any type of surgery or being in labor.
Neuraxial hydromorphone versus control.
Our primary outcome was rest pain score (analogue scale, 0-10) at 24 h according to route of administration (epidural versus spinal) and type of surgery (orthopedic versus other). Secondary outcomes included rest pain score at 0-4 and 8-12 h; rates of postoperative nausea and vomiting, and pruritus at 24 h.
Six trials, including 436 patients, were identified. Rest pain score at 24 postoperative hours was significantly reduced in the hydromorphone group, with a mean difference (95 %CI) of -0.4 (-0.8 to -0.1), I <sup>2</sup> = 74 %, p = 0.01. Neuraxial hydromorphone did not increase postoperative nausea and vomiting (risk ratio [95 %CI]: 1.2 [0.8-1.8], I <sup>2</sup> = 27 %, p = 0.47), but increases pruritus (risk ratio [95 %CI]: 3.1 [1.6-5.9], I <sup>2</sup> = 0 %, p = 0.0005). The quality of evidence was very low for our primary and secondary outcomes. In conclusion, there is very low level of evidence that neuraxial hydromorphone provides effective analgesia after surgery or labor, at the expense of an increased rate of pruritus. The improvement in pain scores appears to be clinically insignificant. With only six trials published over a period of 30 years, we were unable to perform a meta-regression.
If neuraxial hydromorphone is to be used regularly, trials focusing on the optimal dose and side-effects should be performed before widely administering this medication into the neuraxial space. More trials focusing on the optimal dose and side-effects should be performed before widely administering this medication into the neuraxial space
Technical Design Report for the PANDA Solenoid and Dipole Spectrometer Magnets
This document is the Technical Design Report covering the two large
spectrometer magnets of the PANDA detector set-up. It shows the conceptual
design of the magnets and their anticipated performance. It precedes the tender
and procurement of the magnets and, hence, is subject to possible modifications
arising during this process.Comment: 10 pages, 14MB, accepted by FAIR STI in May 2009, editors: Inti

One-step synthesis of melem-based supramolecular assemblies and their photocatalytic properties
In this work, melem-based supramolecular assemblies were obtained in one step by thermal treatment of melamine in an autoclave in the presence of sodium chloride. The detailed analysis showed that the obtained powder consists of two phases: poorly crystalline Na-PHI flakes and rod-shaped melem hydrate single crystals (several micrometers long and ~300-500 nm wide). Melem hydrate crystals absorb light in the visible range (Eg = 2.7 eV) and demonstrate photocatalytic activity in the reaction of partial oxidation of benzyl alcohol to benzaldehyde by air under visible light with high selectivity for the target product. At 60% conversion of benzyl alcohol, the selectivity of benzaldehyde formation is above 95%
A Novel Porous Ti-Squarate as Efficient Photocatalyst in the Overall Water Splitting Reaction under Simulated Sunlight Irradiation
A new porous titanium(IV) squarate metal–organic framework (MOF), denoted as IEF-11, having a never reported titanium secondary building unit, is successfully synthesized and fully characterized. IEF-11 not only exhibits a permanent porosity but also an outstanding chemical stability. Further, as a consequence of combining the photoactive Ti(IV) and the electroactive squarate, IEF-11 presents relevant optoelectronic properties, applied here to the photocatalytic overall water splitting reaction. Remarkably, IEF-11 as a photocatalyst is able to produce record H amounts for MOF-based materials under simulated sunlight (up to 672 µmol g in 22 h) without any activity loss during at least 10 d.P.S.-A. and A.A.B. contributed equally to this work.

Class 1 Integrons in Resistant Escherichia coli and Klebsiella spp., US Hospitals
We examined Escherichia coli and Klebsiella spp. from US hospitals for class 1 integrons. Of 320 isolates, 181 (57%) were positive; association of integrons with resistance varied by drug and organism. Thus, determining integron epidemiology will improve understanding of how antibacterial resistance determinants spread in the United States

Physics Performance Report for PANDA: Strong Interaction Studies with Antiprotons
To study fundamental questions of hadron and nuclear physics in interactions
of antiprotons with nucleons and nuclei, the universal PANDA detector will be
built. Gluonic excitations, the physics of strange and charm quarks and nucleon
structure studies will be performed with unprecedented accuracy thereby
allowing high-precision tests of the strong interaction. The proposed PANDA
detector is a state-of-the art internal target detector at the HESR at FAIR
allowing the detection and identification of neutral and charged particles
generated within the relevant angular and energy range. This report presents a
summary of the physics accessible at PANDA and what performance can be
expected.Comment: 216 page
