To compare the efficacy of dexmedetomidine and magnesium sulfate as an adjuvant to local anesthetics in spinal anesthesia.

A search of PubMed, Medline, Embase, the Cochrane Library, and Google Scholar was performed. Randomized controlled trials comparing the efficacy of dexmedetomidine and magnesium sulfate as a local anesthetic adjuvant in spinal anesthesia were identified. The primary outcome was sensory block duration. The mean difference (MD) or odds ratio along with the 95% confidence interval (CI) was used to analyze the outcomes.

Six studies involving 360 patients were included. Intrathecal dexmedetomidine was associated with a significantly longer sensory block duration (MD = -73.62; 95% CI = -101.09 to -46.15), faster onsets of sensory blockade and motor blockade, and a longer motor block duration than intrathecal magnesium sulfate. There was no significant difference between the regarding the rates of hypotension, bradycardia, shivering, and postoperative nausea and vomiting between the groups.

Dexmedetomidine is superior to magnesium sulfate as an adjuvant to local anesthetics in spinal anesthesia because of its more rapid onset and longer duration of spinal block without significant adverse effects.

The frequency of clinical relapse in encephalitis ranges from 12% to 35%. Commonly, individuals diagnosed with LE experience relapses or breakthrough seizures during their post-acute treatment. The treating neuropsychologist will often need to do family and staff education regarding the disorder, possible unusual pattern of recovery and discuss the risk of relapse. Additionally, staff may need help with behavior management and the potential need for a behavior management plan. This manuscript presents a review of these complex issues and reviews how these issues manifest in five individuals who were admitted to a post-acute brain injury rehabilitation program. Only one achieved significant functional gains, as measured by the Mayo Portland Adaptability Inventory(MPAI-4). Each had a low level of functioning on admission with low scores on the Orientation-Log (O-Log) and high scores on the MPAI-4. Relapse involving need for re-admission to an acute setting occurred in four cases and medication side effects (sedation) in three. As a whole, these cases highlight the complex and potentially unusual course of recovery in individuals with LE.

The duration of optotype presentation in a visual acuity test is an important co-determinant of the test outcome. Most typically, acuity tests are self-paced, which implies an influence of personality on visual acuity test results and a possible lack of transferability to dynamic real-world conditions. Previous studies demonstrated a strong detrimental effect on acuity in the sub-second range, while also revealing further improvement for longer presentation durations of multiple seconds. These studies were performed with normal vision and proposed, besides signal integration, small physiological fluctuations in retinal image quality as underlying the duration effect. In the present study, these fluctuations are overridden by artificial degradation of vision in order to assess their relevance.

Visual acuity was measured with the Freiburg Acuity and Contrast Test with 5 different optotype presentation durations (0.1-10 s). Each of 16 participants was tested with normal vision and with artificially degraded between normal and degraded vision.Background 'Drug holidays' (DH) for metastatic colorectal cancer (mCRC) were introduced to preserve quality of life. We studied factors associated to a DH offer in first line. Materials & methods We retrospectively analyzed 754 consecutive patients treated with chemotherapy for mCRC in two Italian institutions between 2005 and 2017. Associations between baseline clinical-pathological factors and DH (56 or more days of treatment interruption) were investigated. Results In 754 patients, previous metastasectomy, previous thermoablation and previous surgery of primary tumor were independently associated with DH. Excluding procedures or clinical trials primary rectal cancer and resection of primary tumor were significantly associated to DH. Conclusions DH was offered to patients with lower burden of disease, but further investigations are needed to safely guide a holiday strategy.

To evaluate the efficacy and safety of the addition of local infiltration analgesia (LIA) to adductor canal block (ACB) for pain control after primary total knee arthroplasty (TKA).

Two reviewers independently searched for potentially relevant published studies using electronic databases, including PubMed® (1966 to June 2019), Embase® (1974 to June 2019) and Web of Science (1990 to June 2019). The results were pooled using the random-effects model to produce standard mean differences for continuous outcome data and odds ratio for categorical outcome data.

A total of three randomized controlled trials (RCTs) and three non-RCTs were included for data extraction and meta-analysis. There were significant differences between the two groups regarding the postoperative pain score on postoperative day (POD) 0 and POD 1. The cumulative opioid consumption in the ACB plus LIA groups was significantly lower than that in the ACB groups on POD 0 and POD 1. No significant differences were found in terms of postoperative range of motion or length of hospitalization.

ACB plus LIA significantly reduced the postoperative pain score on POD 0 and POD 1 compared with isolated ACB. In addition, ACB plus LIA was associated with a significant reduction in opioid consumption during the early postoperative period.

It has been suggested that the first bacterial exposure is via a placental microbiome. However, despite many publications, the robustness of the evidence for the placental microbiome and transfer of bacteria from the placenta to the infant gut is unclear and hence the concept disputed. Therefore, we conducted a systematic review of the evidence for the role of the placental, amniotic fluid and cord blood microbiome in healthy mothers in the colonization of the infant gut. Most of the papers which were fully assessed considered placental tissue, but some studied amniotic fluid or cord blood. Great variability in methodology was observed especially regarding sample storage conditions, DNA/RNA extraction, and microbiome characterization. No study clearly considered transfer of the normal placental microbiome to the infant gut. Moreover, some studies in the review and others published subsequently reported little evidence for a placental microbiome in comparison to negative controls. In conclusion, current data are limited and provide no conclusive evidence that there is a normal placental microbiome which has any role in colonization of infant gut.

Inflammation and viral infections can induce significant changes in lipid metabolism. Hypertriglyceridemia (HTG) often occurs secondary to obesity, which is an independent risk factor for influenza virus infection. However, the inflammatory risk factors contributing to HTG in patients with severe influenza have yet to be elucidated.

Plasma and bronchoalveolar lavage fluid (BALF) samples were collected from 33 patients with severe influenza (n = 26 control patients with normal serum triglyceride levels and n = 7 HTG patients with serum triglycerides >2.3 mM). Levels of 45 putative inflammatory risk factors were quantitated using a commercial enzyme-linked immunosorbent assay kit.

Plasma levels of interferon (IFN)-γ, interleukin (IL)-18, IL-1 receptor antagonist (IL-1RA), monocyte chemoattractant protein-1, macrophage inflammatory protein-1α, hepatocyte growth factor, stem cell factor, and vascular endothelial growth factor A were significantly higher in HTG patients compared with control patients. BALF samples from HTG patients contained significantly higher levels of IL-1RA and lower levels of IFN-γ-inducible protein-10.

HTG in patients with severe influenza is associated with alterations in several inflammatory risk factors. Our results provide new insights that may enable more effective clinical management of severe influenza combined with HCT.

Therefore, to carefully monitor safety and preserve human health, the development of rapid, accurate, and high-sensitivity determination methods of NAs is of substantial importance. This review provides a current-status comprehensive summary of the pretreatment and determination methods of NAs in various samples since 2010. Common pretreatment methods that have been used to extract and purify targets include solid-phase extraction, liquid-liquid extraction and various microextraction methods, such as solid-phase microextraction and liquid-phase microextraction, among others. Determination methods include liquid chromatography, gas chromatography, supercritical fluid chromatography and electrochemical methods, among others. In addition, we discuss and compare the advantages and disadvantages of various pretreatment and analytical methods and examine the prospects in this area.Detailed understanding of longitudinal behavior, response to therapy, and applicable biomarkers for interstitial lung diseases (ILDs) is lacking. There is a need for a large multicenter registry that provides researchers and clinicians access to well-characterized data not limited to patients with idiopathic pulmonary fibrosis. The Pulmonary Fibrosis Foundation Patient Registry (PFF-PR) is a database that collects baseline and longitudinal demographic and clinical information about patients with ILDs in the United States. The objective of this study is to describe the patient population, data collection process, and opportunities for retrospective and prospective research with the PFF-PR. Individuals 18 years or older who had ILD diagnosed and who were seen at PFF-PR centers who provided informed consent were eligible to participate. Baseline and longitudinal demographic, spirometric, radiographic, morbidity, and mortality data are recorded into a secure electronic data capture system. WR19039 Starting in 2016, the PFF-PR has collected data on 2,003 patients at 42 clinical sites in the United States.
