Subcutaneous administration of low-molecular-weight heparin (LMWH) may cause complications such as haematoma, bruising and pain at different injection sites. Several studies have been carried out to investigate whether bruising and pain depend on injection sites; however, the results have been conflicting, and a clear consistent conclusion has not been reached. The purpose of this systematic review and meta-analysis was to assess the incidence and severity of bruising and pain after subcutaneous injection of LMWH in different sites.

Two reviewers independently searched the Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI) databases for randomized controlled and self-controlled trials reporting side-effects from LMWH with different subcutaneous injection sites. Cochrane bias risk assessment tools and the Newcastle-Ottawa Scale (NOS) were used to evaluate the quality of the randomized controlled and self-controlled trials, respectively. Rev Man 5.3 software was used to analysence interval 0.48-0.67; I

=81%; p<.05), but no statistically significant difference was shown between the pain intensity in the abdominal and arm area (mean difference -1.64; 95% confidence interval -4.36 to 1.08; I

=99%; p>.05).

Subcutaneous injection of LMWH in the abdominal area could reduce the incidence of side-effects at the injection site and reduce patient discomfort. The abdomen is proposed as the first choice of injection site for LMWH. The findings provide useful information to nurses in clinical practice when choosing the subcutaneous injection site for LMWH.

Conventionally, pigments marketed on an industrial scale are produced through chemical synthesis by using petroleum derivatives as the main raw material. Also, the current production chain of the synthetic dyes is linear, with no solvent recycling and waste generation. Thus, the most promising processes of extraction and purification of natural pigments and strategies on the polishing of the solvents are here reviewed. In this review, the use of alternative solvents, namely, ionic liquids, eutectic solvents, aqueous solutions of surfactants, and edible oils, for recovering natural pigments was reviewed. Works discussing higher extraction yields and selectivity, while maintaining the stability of the target pigments, were reported. Also, a panorama between Sustainability and Circular Economy prospection was discussed for better comprehension of the main advances in the field. Behind the analysis of the works published so far on the theme, the most important lacunas to overcome in the next years on the field were pointed out and discussed. Also, the future trends and new perspectives to achieve the economic viability and sustainability of the processes using alternative solvents will be scrutinized.The coronavirus disease 2019 (COVID-19) pandemic is currently not under control. We aimed to assess whether there are differences in clinical manifestations between COVID-19 patients from the East (East and South-East Asian countries including China, South Korea, and Thailand) and the West (North American, European, and Middle East countries, including the United States, Italy, France, and Iran). For this meta-analysis, we searched for eligible studies about COVID-19 in three databases PubMed, EMBASE, and the Cochrane Library. Studies were divided into two cohorts for analysis the East and the West. Stata 13.1 software was used for the meta-analysis. Of the 1527 studies initially identified by the literature search, 169 full-text articles were retrieved and screened for eligibility. Fifty-seven of these, describing 19,353 patients, were deemed eligible for inclusion. Of these, 45 studies with 8416 patients were from the East while 12 studies with 10,937 patients were from the West. The results indicated that the incidences of cough, headache, dizziness, nasal congestion, and digestive symptoms in COVID-19 patients from the East were lower than those in the West. The laboratory data showed that there were no significant differences in the levels of lymphocytes, leukocytes, C-reactive protein, and platelet counts between the two groups. In addition, our results also showed that the incidence of cardiac and kidney injury, as well as increased levels of creatinine, alanine transaminase, and aspartate transaminase, were significantly higher in patients from the West than from the East. selleck compound Our meta-analysis indicated that there are differences in the clinical manifestations of COVID-19 in patients from the East and the West. COVID-19 patients from the West appear to suffer more severe liver, kidney, and heart damage due to SARS-CoV-2.Planktonic microorganisms play a key role in the biogeochemical processes of the aquatic system, and they may be affected by many factors. High-throughput sequencing technology was used in this study to investigate and study the bacterioplankton community of water bodies in the upper reaches of the Heihe River Basin in Qinghai Plateau. Results showed that Proteobacteria, Firmicutes, Bacteroidetes and Actinobacteria are the predominant phyla in this river section, while the main genera are Thiomonas, Acidibacillus, Acidocella, Rhodanobacter, Acidithiobacter and Gallionella, which are autochthonous in the acid-mine drainage. Additionally, total nitrogen, total phosphorus, permanganate index and pH are significantly correlated with the bacterioplankton abundance and are the main limiting factors for the spatial distribution of the bacterioplankton. PICRUSt inferred that the mainstream microbial assemblages had a higher abundance of KOs belong to metabolism of terpenoids and polyketides, while the tributary had higher abundance of KOs belong to the immune system. The relationship between bacterioplankton community composition and environmental factors in the Heihe River basin was discussed for the first time in this study, which provides a theoretical basis for the healthy, orderly development of the water environment in the Heihe River Basin.Highlights In Chinese patients with type 2 diabetes (T2D) and body mass index (BMI) less then 25 kg/m2 , dulaglutide demonstrated great improvements in glycemic control with mild body weight reduction and low hypoglycemia risk. The results indicate that dulaglutide is effective and safe in patients with T2D and lower BMI; therefore, BMI should not be a consideration when dulaglutide is prescribed to Chinese patients with T2D.

Brown-Vialetto-Van Laere syndrome (BVVLS) and Fazio-Londe disease (FLD) are rare neurological disorders presenting with pontobulbar palsy, muscle weakness and respiratory insufficiency. Mutations in SLC52A2 (hRFVT-2) or SLC52A3 (hRFVT-3) genes can be responsible for these disorders with an autosomal recessive pattern of inheritance. The aim of this study was to screen for mutations in SLC52A2 and SLC52A3 among Indian families diagnosed with BVVLS and FLD.

SLC52A2 and SLC52A3 were screened in one FLD and three BVVLS patients by exon-specific amplification using PCR and sequencing. In silico predictions using bioinformatics tools and confocal imaging using HEK-293 cells were performed to determine the functional impact of identified mutations.

Genetic analysis of a mother and son with BVVLS was identified with a novel homozygous mutation c.710C>T (p.Ala237Val) in SLC52A3. This variant was found to have an autosomal pseudodominant pattern of inheritance, which was neither listed in the Exome Variant Server or in the 1000 Genomes Project database. In silico analysis and confocal imaging of the p.Ala237Val variant showed higher degree of disorderness in hRFVT-3 that could affect riboflavin transport. Furthermore, a common homozygous mutation c.62A>G (p.Asn21Ser) was identified in other BVVLS and FLD patients. Despite having different clinical phenotypes, both BVVLS and FLD can be attributed to this mutation.

A rare and peculiar pattern of autosomal pseudodominant inheritance is observed for the first time in two genetically related BVVLS cases with Indian origin and a common mutation c.62A>G (p.Asn21Ser) in SLC52A3 can be responsible for both BVVLS and FLD with variable phenotypes.

G (p.Asn21Ser) in SLC52A3 can be responsible for both BVVLS and FLD with variable phenotypes.

In this study, we seek to empirically understand the relationship between lifestyle habits and dementia risk.

Through an original online survey, we first confirm the significant difference in the dementia risk indicators between good and bad lifestyle habits. Then, using regression analysis to hold other factors equal, we examine the relationships between lifestyle habits and an aggregate dementia risk indicator.

Through the t-test results, we find that the average scores of dementia risk for respondents avoiding good habits and preferring bad habits are significantly higher than those of the respondents favoring good habits and avoiding bad habits. Our empirical findings showed that Japanese-style dietary habits significantly correlate with a decreased dementia risk. An additional 1-point increase in eating habits will reduce dementia risk scores by 0.148 points, on average. Furthermore, we also confirm that walking (more than three times per week) and watching TV (almost every day) help prevent dementber of older adults with dementia.

In this work, through combined theoretical and experimental model investigations, we elucidate that the electric double layer (EDL) chemistry at the electrode/electrolyte interface beyond the thermodynamic stability of electrolyte components predominately controls the competitive reduction reactions during SEI construction on Li metal anode. Specifically, the negatively-charged surface of Li metal will prompt substantial cation enrichment and anion deficiency within the EDL. Necessarily, only the species participating in the solvation shell of cations could be electrostatically accumulated in proximity of Li metal surface and thereafter be preferentially reduced during sustained dynamic cycling. Incorporating multi-valent cation additives to more effectively drag the favorable anionic SEI enablers into EDL is validated as a promising strategy to upgrade the Li protection performance. The conclusions drawn herein afford deeper understandings to bridge the EDL principle, cation solvation, and SEI formation, shedding fresh light on the targeted regulation of reactive alkali metal interfaces.Animal evolution transformed microbial mat development. Canonically inferred negative effects include grazing, disturbance and competition for space. In contrast, ancient examples of cooperation between microbial mats and invertebrates have rarely been reported. Late Cambrian (~485 million years) Cryptozoön is widely regarded as the first stromatolite to have received a taxonomic name and has been compared with present-day examples at Shark Bay, Australia. Here, we show that Cryptozoön is an interlayered consortium of keratose ('horny') sponge and microbial carbonate in roughly equal proportions. Cryptozoön's well-defined layering reflects repeated alternation of sponge and microbial mat. Its distinctive lateral growth is due to the ability of keratosans to colonize steep and overhanging surfaces. Contrary to the perception of Phanerozoic stromatolites as anachronistic survivors in a eukaryotic world, Cryptozoön suggests mutualistic behaviour in which sponges and microbial mats cooperated to gain support, stability and relief, while sharing substrates, bacteria and metabolites.
