A Phage Display-Identified Small Peptide Able to Hydrolyzing Calcium Pyrophosphate Crystals-The Etiological Aspect regarding Chondrocalcinosis.
We subsequently examined the relationships between ectomycorrhizal root abundance, leaf traits, and slow and fast pools of soil organic carbon and nitrogen. The ratio of leaf ligninN, but not its components, increased along with ectomycorrhizal root abundance in subsoils. Soil carbon and nitrogen pools were independent of ectomycorrhizal root abundance. Our results suggest that (1) categorizing aspen as dual-mycorrhizal may overstate the functional importance of arbuscular mycorrhizas in this species and life stage, (2) water availability influences ectomycorrhizal root abundance, and (3) ectomycorrhizal root abundance coincides with leaf quality.
Cerebral haemorrhage is a life-threatening event with various causes including adverse drug reactions (ADRs). Several methods have been proposed for the causality assessment of ADRs, but none specific for cerebral haemorrhage. The purpose of this study was to develop an algorithm for causality assessment between drugs and fatal cerebral haemorrhage, based on the analysis of data from the Japanese Adverse Drug Event Report (JADER) database and literature review.

All fatal ADRs reported in the JADER database between April 2004 and March 2020 were searched, and literature on drug-related cerebral haemorrhage or general causality assessment was reviewed to summarise the information on causality between cerebral haemorrhage and ADRs.

Of the 50,095 cases identified in the JADER database, cerebral haemorrhage was the fifth most reported cause of fatal ADRs, but the causality of >80% of the events was published as 'Unassessable'. The literature review identified articles on drug-related cerebral haemorrhage and causality assessment methods in general. Based on these articles, information on five categories (temporal relationship, previous knowledge about the relationship between drug action and ADRs, alternative aetiological candidate, appropriateness of drug use, and the relationship between death and ADRs) was determined for causality assessment between a suspected drug and fatal cerebral haemorrhage; a new algorithm was created using this information.

In this study, the information considered necessary for causality assessment between drugs and fatal cerebral haemorrhage was reviewed and an assessment algorithm was developed. Future studies are needed to validate the usefulness of this method.

Naltrexone is used to examine if saccharin effect is mediated via the endogenous opioid system. Pain in rat pups was induced via needle pricks of the paws on day 1 of their birth (P0). All treatments/ manipulations started on day 1 and continued for 2 weeks. The radial arm water maze (RAWM) test was used to assess learning and memory. Pain threshold through foot-withdrawal response to a hot plate was also assessed. At the end of behavioral tests, animals were killed, hippocampus was dissected, and hippocampal levels of β-endorphin, enkephalin, and brain-derived neurotropic factor (BDNF) were assessed using ELISA. Naltrexone and saccharin combined normalized noxious stimulation induced increased pain sensitivity later in life. Furthermore, naltrexone and saccharin together mitigated the deficiency in learning and memory induced by noxious stimulation. Saccharin treatment prevented reduction in hippocampal enkephalin. Additionally, saccharin prevented hippocampal noxious stimulation induced BDNF decrement. Saccharin prevented long-term memory impairment during adulthood induced by repeated neonatal pain via mechanisms that appear to involve BDNF. Interestingly, naltrexone did not antagonize the effects of saccharin, instead naltrexone augmented saccharin effects.
Tamibarotene is a synthetic retinoid that inhibits proliferation and induces differentiation of malignant cells by binding to the retinoic acid receptor α/β. Previous in vitro studies have shown that some pediatric solid tumors with retinoic acid receptors differentiate in response to retinoic acid. We conducted a phase I dose-escalation study to determine the recommended dose of tamibarotene for further study in pediatric and young adult patients with recurrent/refractory solid tumors.

Pediatric and young adult patients with recurrent/refractory solid tumors were administered tamibarotene at 4, 6, 8, 10, and 12mg/m
/day for 14 or 21days of a 28day cycle. Safety, efficacy, and pharmacokinetics of tamibarotene were evaluated.

Twenty-two patients (median age 8years) were enrolled in this study. No dose-limiting toxicity (DLT) was encountered, and tamibarotene was generally well tolerated. Two patients experienced severe adverse events (AEs), leading to discontinuation of the treatment. One grade 4 venous thrombosis and one grade 2 erythema multiforme were observed, which promptly resolved after tamibarotene discontinuance. The grade 4 venous thrombosis was a severe AE but not DLT because it occurred after the evaluation period. Pharmacokinetic analyses showed a dose-dependent increase in the maximum drug concentration (C
) and area under the concentration-time curve (AUC). None of the patients achieved a complete response or partial response. Seven patients had stable disease lasting longer than 18weeks.

The recommended dose for phase II study of tamibarotene in pediatric and young adult patients with refractory solid tumors is 12mg/m
/day for 21days in a 28day cycle.
The recommended dose for phase II study of tamibarotene in pediatric and young adult patients with refractory solid tumors is 12 mg/m2/day for 21 days in a 28 day cycle.Vibrio fluvialis is a halophilic bacterium frequently found in estuarine and coastal waters environments. The strain 362.3 was isolated from Mussismilia braziliensis coral of Abrolhos Bank. In this study, to gain insights into the marine adaptation in V. fluvialis, we sequenced the genome of 362.3 strain, which comprised 4,607,294 bp with a G + C content of 50.2%. In silico analysis showed that V. Danicamtiv concentration fluvialis 362.2 encodes genes related to chitin catabolic pathway, iron metabolism, osmotic stress and membrane transport.This study aimed to investigate the prevalence of fractures and non-fracture injuries, including associated risk factors, in children with epilepsy prescribed antiseizure medications (ASM). A controlled, cross-sectional study was conducted in a hospital outpatient setting, comparing children with epilepsy prescribed ASMs with their non-epileptic siblings. Information was collected by questionnaire included history of fractures, non-fracture injuries and epilepsy, comorbidities and ASM use. 261 participants completed the questionnaire, 133 children with epilepsy (aged 10.7 ± 3.5 years, mean ± SD) and 128 siblings (10.1 ± 3.7 years). There were 49 non-seizure-related fractures in 34 ASM patients while prescribed ASMs, compared with 21 lifetime fractures in 15 controls, giving a 2.7 (95% CI 1.3-5.3, p = 0.007) times greater fracture prevalence in children treated with ASMs compared to healthy siblings. The rates of non-fracture injuries were similar across groups, except that concussion was more common in children taking ASMs (9.0% vs 1.6%, p = 0.026). Duration of ASM use and generalized tonic-clonic seizures (GTCS) were independent predictors of fractures (OR 1.55; 95% CI 1.03-2.31, p = 0.03; OR 2.50; 95% CI 1.05-5.94, p = 0.04, respectively). Fewer than 20% of participants and/or their families were aware that ASM use was related to bone health. Children with epilepsy treated with ASMs had a higher fracture prevalence than their sibling controls. Duration of ASM treatment and GTCS were associated with fracture risk. Longitudinal prospective studies are required to further explore risk and the direct impact of epilepsy on bone health.This systematic review and meta-analysis suggests that fracture liaison service (FLS) is associated with a significantly lower probability of subsequent fractures and mortality although the latter was only found in studies comparing outcomes before and after the introduction of an FLS.
To systematically review and evaluate the impact of fracture liaison services (FLSs) on subsequent fractures and mortality using meta-analysis.

A literature search was performed within PubMed and Embase to identify original articles published between January 1, 2010, and April 30, 2020, reporting the effect of FLSs on subsequent fractures and/or mortality. Only studies comparing FLS to no-FLS were included. A meta-analysis using random-effects models was conducted. The quality of studies was appraised after combining and modifying criteria of existing quality assessment tools.

The search retrieved 955 published studies, of which 16 studies fulfilled the inclusion criteria. Twelve studies compared outcomes before (pre-FLS) mortality although the latter was only found in studies comparing outcomes before and after the introduction of an FLS. The quality assessment revealed that some important methodological issues were unmet in the currently available studies. Recommendations to guide researchers to design high-quality studies for evaluation of FLS outcomes in the future were provided.
The present review is intended to provide an up-to-date overview of the strategies available to detect malingered symptoms following whiplash. Whiplash-associated disorders (WADs) represent the most common traffic injuries, having a major impact on economic and healthcare systems worldwide. Heterogeneous symptoms that may arise following whiplash injuries are difficult to objectify and are normally determined based on self-reported complaints. These elements, together with the litigation context, make fraudulent claims particularly likely. Crucially, at present, there is no clear evidence of the instruments available to detect malingered WADs.

We conducted a targeted literature review of the methodologies adopted to detect malingered WADs. Relevant studies were identified via Medline (PubMed) and Scopus databases published up to September 2020.

Twenty-two methodologies are included in the review, grouped into biomechanical techniques, clinical tools applied to forensic settings, and cognitive-based lie possibility of malingering. We conclude that it is pivotal to promote awareness about the presence of malingering in whiplash cases and highlight the need for novel, high-quality research in this field, with the potential to contribute to the development of standardised procedures for the evaluation of WADs and the detection of malingering.Liver disorders due to infections are a substantial health concern in underdeveloped and industrialized countries. This includes not only hepatotropic viruses (e.g., hepatitis B, hepatitis C) but also bacterial and parasitic infections such as amebiasis, leishmaniasis, schistosomiasis, or echinococcosis. Recent studies of the immune mechanisms underlying liver disease show that monocytes play an essential role in determining patient outcomes. Monocytes are derived from the mononuclear phagocyte lineage in the bone marrow and are present in nearly all tissues of the body; these cells function as part of the early innate immune response that reacts to challenge by external pathogens. Due to their special ability to develop into tissue macrophages and dendritic cells and to change from an inflammatory to an anti-inflammatory phenotype, monocytes play a pivotal role in infectious and non-infectious liver diseases they can maintain inflammation and support resolution of inflammation. Therefore, tight regulation of monocyte recruitment and termination of monocyte-driven immune responses in the liver is prerequisite to appropriate healing of organ damage.
