    以羊奶为基础的婴儿配方奶粉(GMF)现在在几个国家有售,经当局批准。我们系统地评估了GMF与基于牛奶的配方(CMF)对婴儿生长和安全性参数的影响。MEDLINE,EMBASE,和CochraneLibrary数据库检索(2022年12月)的随机对照试验(RCTs).使用修订的Cochrane偏差风险工具(ROB-2)评估偏差风险。异质性通过I2量化。确定了四个RCT,涉及670名婴儿。所有试验都显示了对ROB-2的一些关注。此外,所有纳入的研究均由行业资助.与饲喂CMF的婴儿相比,那些饲喂GMF的人在性别和年龄调整后的体重z分数上显示出相似的增长(平均差异,MD,0.21[95%置信区间,CI,-0.16至0.58],I2=56%),长度(MD0.02,[95%CI-0.29至0.33],I2=24%),和头围(MD0.12,95%[CI-0.19至0.43],I2=2%)。各组的大便频率相似。由于粪便稠度报告的差异,不能得出确切的结论。两组的不良反应(严重或任何)相似。这些发现保证了GMF与CMF相比是安全且耐受性良好的。
    Goat-milk-based infant formulas (GMFs) are now available in several countries, having been approved by authorities. We systematically evaluated the effects of GMF compared with cow-milk-based formula (CMF) on infant growth and safety parameters. The MEDLINE, EMBASE, and Cochrane Library databases were searched (December 2022) for randomized controlled trials (RCTs). The risk of bias was assessed using the Revised Cochrane Risk-of-Bias tool (ROB-2). Heterogeneity was quantified by I2. Four RCTs involving a total of 670 infants were identified. All trials revealed some concern in ROB-2. Furthermore, all of the included studies were funded by the industry. Compared with infants fed CMF, those fed GMF showed similar growth in sex- and age-adjusted z-scores for weight (mean difference, MD, 0.21 [95% confidence interval, CI, -0.16 to 0.58], I2 = 56%), length (MD 0.02, [95% CI -0.29 to 0.33], I2 = 24%), and head circumference (MD 0.12, 95% [CI -0.19 to 0.43], I2 = 2%). Stool frequency was similar among the groups. Due to differences in the reporting of stool consistency, no firm conclusion can be drawn. Adverse effects (serious or any) were similar in both groups. These findings provide reassurance that GMFs compared with CMFs are safe and well tolerated.

    地球的地磁场(GMF)是植物不可避免的环境因素,会影响所有生长和产量参数。强磁场和弱磁场(MF),与GMF相比,在植物生长发育中具有特定的作用。MF技术是一种环保技术,不会排放废物或产生有害辐射,也不需要任何外部电源,所以它可以用于可持续的现代农业。因此,植物暴露于MF是一种潜在的负担得起的方法,通过改变生理和生化过程提高作物生产力的可重复使用和安全的做法。然而,MF对植物生理生化过程的影响尚不清楚。这篇综述描述了改变MF条件(高于或低于GMF的值)对植物生理和生化过程的影响。关于MF对植物的不同影响的研究的当前矛盾和不一致的结果可能与物种和/或MF暴露时间和强度有关。综述的文献表明,MF在改变生理过程中发挥作用,比如呼吸,光合作用,营养吸收,水关系和生化属性,包括与ROS有关的基因,抗氧化剂,酶,蛋白质和次级代谢产物。施用MF可以有效地提高许多作物的生长和产量,因此,应该是未来研究的重点。
    The Earth\'s geomagnetic field (GMF) is an inescapable environmental factor for plants that affects all growth and yield parameters. Both strong and weak magnetic fields (MF), as compared to the GMF, have specific roles in plant growth and development. MF technology is an eco-friendly technique that does not emit waste or generate harmful radiation, nor require any external power supply, so it can be used in sustainable modern agriculture. Thus, exposure of plants to MF is a potential affordable, reusable and safe practice for enhancing crop productivity by changing physiological and biochemical processes. However, the effect of MF on plant physiological and biochemical processes is not yet well understood. This review describes the effects of altering MF conditions (higher or lower values than the GMF) on physiological and biochemical processes of plants. The current contradictory and inconsistent outcomes from studies on varying effects of MF on plants could be related to species and/or MF exposure time and intensity. The reviewed literature suggests MF have a role in changing physiological processes, such as respiration, photosynthesis, nutrient uptake, water relations and biochemical attributes, including genes involved in ROS, antioxidants, enzymes, proteins and secondary metabolites. MF application might efficiently increase growth and yield of many crops, and as such, should be the focus for future research.

    UNASSIGNED:与经典MF相比,肉芽肿性真菌病(GMF)的预后较差,并且仍然是一个重要的诊断难题。我们分析了临床病理,免疫表型,和GMF的分子特征来开发诊断算法。我们的方法涉及2014年至2020年数据库中GMF患者的回顾性病例系列研究。总共确定了8例患者,其中9例GMF活检。皮肤表现具有可变的临床表型。组织学上,所有病例均表现为非典型CD4+T细胞浸润,50%(n=4),局灶性37.5%(n=3),并且没有25%(n=2)表皮性。在77.8%的活检(n=7)中发现了肉芽肿形成,其中结节样肉芽肿占57.1%(n=4),环状肉芽肿样类型占42.9%(n=3)。在66.7%的活检中(n=6),CD4:CD8比值>4:1,66.6%(n=6)的活检显示CD7表达缺失≥50%.对活检切片进行的T细胞受体基因重排研究在所有活检中均为阳性(n=6),而外周血T细胞受体基因重排研究未发现克隆性.总之,GMF具有微妙或不存在的表皮性和可变的肉芽肿反应;因此,诊断需要多模式方法,我们提出的算法提供了一个框架来解决这个诊断挑战。
    UNASSIGNED: Granulomatous mycosis fungoides (GMF) harbors a worse prognosis compared with classic MF and remains a significant diagnostic dilemma. We analyzed clinicopathologic, immunophenotypic, and molecular characteristics of GMF to develop a diagnostic algorithm. Our methodology involved a retrospective case series study of patients with GMF from our database between 2014 and 2020. A total of 8 patients with 9 biopsies of GMF were identified. Skin manifestations had variable clinical phenotype. Histologically, all cases demonstrated atypical CD4 + T-cell infiltrate with scant in 50% (n = 4), focal 37.5% (n = 3), and absent 25% (n = 2) epidermotropism. Granuloma formation was seen in 77.8% biopsies (n = 7) with sarcoid-type granulomas in 57.1% (n = 4) and granuloma annulare-like type in 42.9% (n = 3). In 66.7% of biopsies (n = 6), the CD4:CD8 ratio was >4:1 and 66.6% (n = 6) of biopsies showed ≥50% loss of CD7 expression. T-cell receptor gene rearrangement studies performed on biopsy sections were positive in all biopsies (n = 6), whereas peripheral blood T-cell receptor gene rearrangement studies did not identify clonality. In conclusion, GMF has subtle or absent epidermotropism and variable granulomatous reaction; thus, the diagnosis requires a multimodal approach, and our proposed algorithm provides a framework to approach this diagnostic challenge.

    背景:血管手术中的腹股沟伤口感染仍然是一个常见的并发症和具有挑战性的问题。本系统评价旨在建立一个完整的观点,即使用肌瓣进行血管外科重建后感染腹股沟伤口的患者特征和临床结果,并评估缝匠肌瓣(SMF)之间的结果差异。股直肌肌皮瓣(RFF),和股薄肌皮瓣(GMF)。
    方法:PubMed,Scopus,从成立到2021年4月,对WebofScience进行了系统搜索。对合并症和结局进行随机效应荟萃分析,对结局进行亚组分析。
    结果:30项研究纳入了定性和定量综合研究。总体汇总数据显示以下结局率:4.5%的肌瓣坏死(95%置信区间[CI],-3.4-12.3%;I2=0%),总并发症21.8%(95%CI,15.8-27.7%;I2=0%),8.0%肢体丢失(95%CI,1.9-14.1%;I2=0%),移植物损失15.4%(95%CI,5.0-25.3%;I2=37.9%),30天死亡率为7.4%(95%CI,-.9-15.6%;I2=0%)。总并发症发生率为20.3%(95%CI,12.1-28.2%;I2=0%),23.2%(95%CI,11.2-34.5%;I2=10.2%),SMF为18.0%(95%CI,-3.537.8%;I2=0%),RFF,和GMF,分别。GMF的肢体丢失率最高(17.2%;95%CI,-4.237.2%;I2=0%)。RFF的移植物损失率最高(20.7%;95%CI,.6-39.1%;I2=53.9%)。SMF的30天死亡率最低(5.3%;95%CI,-6.1-16.6%;I2=0%)。
    结论:对于血管外科术后腹股沟感染伤口,肌瓣重建的有效性和安全性显然是积极的。这篇综述表明,SMF的并发症发生率低于其他肌肉皮瓣。
    BACKGROUND: Groin wound infections in vascular surgery are still a common complication and challenging problem. This systematic review aimed to establish a complete view of patient characteristics and clinical outcomes for infected groin wounds following vascular surgery reconstruction using muscle flaps and to evaluate the differences in outcomes between the sartorius muscle flap (SMF), rectus femoris muscle flap (RFF), and gracilis muscle flap (GMF).
    METHODS: PubMed, Scopus, and Web of Science were systematically searched from inception to April 2021. Random-effects meta-analysis for comorbidities and outcomes and subgroup analyses for outcomes were performed.
    RESULTS: Thirty studies were included in qualitative and quantitative syntheses. Overall pooled data showed the following outcome rates: 4.5% muscle flap necrosis (95% confidence interval [CI], -3.4-12.3%; I2 = 0%), 21.8% overall complications (95% CI, 15.8-27.7%; I2 = 0%), 8.0% limb loss (95% CI, 1.9-14.1%; I2 = 0%), 15.4% graft loss (95% CI, 5.0-25.3%; I2 = 37.9%), and 7.4% 30-day mortality (95% CI, -.9-15.6%; I2 = 0%). The rates of overall complications were 20.3% (95% CI, 12.1-28.2%; I2 = 0%), 23.2% (95% CI, 11.2-34.5%; I2 = 10.2%), and 18.0% (95% CI, -3.537.8%; I2 = 0%) for the SMF, RFF, and GMF, respectively. The rate of limb loss was highest for the GMF (17.2%; 95% CI, -4.237.2%; I2 = 0%). The rate of graft loss for the RFF was the highest (20.7%; 95% CI, .6-39.1%; I2 = 53.9%). The rate of 30-day mortality was the lowest for the SMF (5.3%; 95% CI, -6.1-16.6%; I2 = 0%).
    CONCLUSIONS: The effectiveness and safety of muscle flap reconstruction for infected groin wounds following vascular surgery are clearly positive. This review indicated a tendency for lower complication rates with the SMF than with other muscle flaps.

    文章类型: English Abstract
    Glia maturation factor-beta (GMFB) is a 17-kDa protein that was initially identified as a growth and differentiation factor acting on neurons as well as glia in the vertebrate brain. We isolated human and rat glia maturation factor-gamma (GMFG) cDNA and examined the tissue distribution of GMFG in human and rat by Northern blots and Western blots. Sequence analysis of the entire cDNA revealed an open reading frame of 426 nucleotides with a deduced protein of 142 amino acid residues. The deduced amino acid sequence of its putative product is highly homologous to GMFB. Northern blot analysis indicated that a 0.9 kb mRNA is predominantly expressed in rat thymus, testis, and spleen. In comparison with GMFB, the current study demonstrated that the tissue distribution of GMFG is not the same as that of GMFB, and GMFG is predominantly in proliferative and differentiative organs.
