Meningoencephalitis secondary to Listeria monocytogenes (L. monocytogenes) mainly affects newborns, the elderly and immunocompromised people;there are extremely rare cases in which said infection occurs in immunocompetent individuals. We present the case of a young adult patient without immunocompromise, who developed meningoencephalitis due to L. monocytogenes;This case is exceptional, since it occurred in an individual outside the classic age group, in addition to not having risk factors, which is why it should be considered an atypical causal agent.

There are five vital signs that healthcare providers assess: temperature, pulse, respiration, blood pressure, and pain. Normal levels for the five vital signs are published by the American heart Association, and other specialty organizations, however, the sixth vital sign (resilience) which adopts the measure of immune resilience is suggested in this paper. Resilience is the ability of the immune system to respond to attacks and defend effectively against infections and inflammatory stressors, and psychological resilience is the capacity to resist, adapt, recover, thrive, and grow from a challenge or a stressor. Individuals with better optimal immune resilience had better health outcomes than those with minimal immune resilience. The purpose of this paper is to conceptualize, contextualize, and operationalize all six vital signs. We suggest measuring resilience subjectively and objectively. Subjectively, use a 5-item guided interview revised from the Connor-Davidson Resilience Scale (CDRC), a scale of 10 items. The revised CDRC scale is a 5-item scale. The scale is rated on a 5-point Likert scale from 0 (not true) to 4 (true all the time). The total score ranges from 0 to 20, with higher total scores indicating greater resilience. The scale demonstrated good construct validity and internal consistency (α = 0.85) during the development of the scale. The CD-RISC had a good Cronbach’s alpha level of 0.85. The Revised CD-RISC can be completed in 2 - 4 minutes. To measure resilience objectively, we suggest using Immune Resilience (IR) levels, the level of resilience to preserve and/or rapidly restore immune resilience functions that promote disease resistance and control inflammation and other inflammatory stress. IR levels are gauged with two peripheral blood metrics that quantify the balance between CD8 and CD4 T-cell levels and gene expression signatures tracking longevity-associated immunocompetence and mortality- or entropy-associated inflammation.

多种与水分和热量相关的极端气候事件对青藏高原植被生长造成了不利影响.然而,目前尚不清楚多大程度的极端气候胁迫水平会导致植被生长出现强烈响应.为了填补这一知识空白,我们综合利用水文气象数据和卫星遥感获取的植被指数,检测了2001~2018年间影响植被生产力对干旱、极端高温和极端低温响应的两个关键气候阈值(反映植被生产力响应发生突变和对植被损害达到最大).结果表明,当土壤湿度下降到正常水平的(-1.41±0.6)个标准差(σ)以下时,植被生产力对干旱事件的响应频率会迅速增加;当土壤湿度低于(-2.98±0.9)σ时,干旱对植被生产力造成的损害达到最大.区域上极端低温的阈值平均值为(-1.44±0.5)σ和(-2.53±0.8)σ,而极端高温的阈值平均值为(1.34±0.4)σ和(2.31±0.4)σ.这表明,极端高温比极端低温更易引发植被生产力的强烈响应.此外,我们发现极端温度事件中土壤水分亏缺的复合效应降低了极端低温和极端高温的阈值.基于地球系统模式预测,到2100年,青藏高原的西南部和东北部的部分地区将有极高的风险受到超过阈值的极端气候事件影响.本研究基于极端气候阈值识别了青藏高原地区具有高影响力的极端气候事件,提高了对不同极端气候事件植被生长响应的认识,为评估极端气候事件对区域生态系统的影响提供了研究范例.

Persistent organic pollutants(POPs) such as organochlorine pesticides are of global concern due to their widespread occurrence and persistence. This paper reports recent research studying the distribution and fate of organochlorine pesticides in the Jiulong River, the Minjiang River and the Pearl River estuaries in Southeast China. Eighteen organochlorine pesticides were extracted from water, pore water and sediment samples, followed by analysis by gC ECD. The results showed that the contamination levels were similar in these three estuaries. The levels of the total organochlorine pesticides in porewater were significantly higher than those in surface water, due to the high affinity of these hydrophobic compounds for sediment phase. Among the hexachlorocyclohexane(hCh) compounds, β hCh was found to be the most important isomer. The analysis of 1,1,1 trichloro 2,2 bis chlorophenyl ethane(DDT) and its metabolites showed that 1,1 dichloro 2[ o chlorophenyl] 2[ p chlorophenyl] ethylene(DDE) was dominant in the group.
