Evidence on follow-up duration for patients with sporadic pheochromocytomas is absent, and current guidelines of the European Society of Endocrinology, American Association of Clinical Endocrinologists and Endocrine Surgeons, and the Endocrine Society are ambiguous about the appropriate duration of follow-up. The aim of this systematic review and meta-analysis is to evaluate the recurrence rate of sporadic pheochromocytomas after curative adrenalectomy.
A literature search in PubMed, Embase, and the Cochrane Library was performed. A study was eligible if it included a clear report on the number of sporadic patients, recurrence rate, and follow-up duration. Studies with an inclusion period before 1990, <2 years of follow-up, <10 patients, and unclear data on the sporadic nature of pheochromocytomas were excluded. A meta-analysis on recurrence was performed provided that the heterogeneity was low (I2 < 25%) or intermediate (I2 26-75%). Hozo's method was used to calculate weighted mean follow-up duration and weighted time to recurrence with combined standard deviations (SDs).
A total of 13 studies, including 430 patients, were included in the synthesis. The meta-analysis results describe a pooled recurrence rate after curative surgery of 3% (95% confidence interval 2-6%, I2 = 0%), with a weighted mean time to recurrence of 49.4 months (SD = 30.7) and a weighted mean follow-up period of 77.3 months (SD = 32.2).
This meta-analysis shows a very low recurrence rate of 3%. Prospective studies, including economical and health effects of limited follow-up strategies for patients with truly sporadic pheochromocytomas should be considered.

No prior studies have used a single sample of bereaved families of cancer patients to compare multiple scales for assessing Complicated Grief. Here, we compare the two measures.
We sent a questionnaire to the bereaved families of cancer patients who had died at 71 palliative care units nationwide.
The analysis included 3173 returned questionnaires. Prevalence of Complicated Grief was 7.8% by Brief Grief Questionnaire (with a cutoff score of 8) and 15.5% for Inventory of Complicated Grief (with a cutoff score of 26). The Spearman's correlation coefficient between the Brief Grief Questionnaire and the Inventory of Complicated Grief was 0.79, and a ceiling effect was seen for the distribution of the Brief Grief Questionnaire scores. Although 6.4% of respondents scored both 8 or higher on the Brief Grief Questionnaire and 26 or higher on the Inventory of Complicated Grief, only 1.4% scored both 8 or higher on the Brief Grief Questionnaire and <26 on the Inventory of Complicated Grief. In contrast, 9.1% s and specificity, will be necessary.Glycans serve important roles in signaling events and cell-cell communication, and they are recognized by lectins, viruses and bacteria, playing a variety of roles in many biological processes. However, there was no system to organize the plethora of glycan-related data in the literature. Thus GlyTouCan (https//glytoucan.org) was developed as the international glycan repository, allowing researchers to assign accession numbers to glycans. This also aided in the integration of glycan data across various databases. GlyTouCan assigns accession numbers to glycans which are defined as sets of monosaccharides, which may or may not be characterized with linkage information. GlyTouCan was developed to be able to recognize any level of ambiguity in glycans and uniquely assign accession numbers to each of them, regardless of the input text format. In this manuscript, we describe the latest update to GlyTouCan in version 3.0, its usage, and plans for future development.Ever since gene targeting or specific modification of genome sequences in mice was achieved in the early 1980s, the reverse genetic approach of precise editing of any genomic locus has greatly accelerated biomedical research and biotechnology development. In particular, the recent development of the CRISPR/Cas9 system has greatly expedited genetic dissection of 3D genomes. CRISPR gene-editing outcomes result from targeted genome cleavage by ectopic bacterial Cas9 nuclease followed by presumed random ligations via the host double-strand break repair machineries. Recent studies revealed, however, that the CRISPR genome-editing system is precise and predictable because of cohesive Cas9 cleavage of targeting DNA. Here, we synthesize the current understanding of CRISPR DNA fragment-editing mechanisms and recent progress in predictable outcomes from precise genetic engineering of 3D genomes. Specifically, we first briefly describe historical genetic studies leading to CRISPR and 3D genome engineering. We then summarize different types of chromosomal rearrangements by DNA fragment editing. Finally, we review significant progress from precise 1D gene editing toward predictable 3D genome engineering and synthetic biology. The exciting and rapid advances in this emerging field provide new opportunities and challenges to understand or digest 3D genomes.
Existing scholarship in social gerontology has paid relatively little attention to broader loving emotions, such as compassionate and altruistic love, as potentially meaningful mechanisms for improving later-life psychological well-being outside a family framework.
Drawing from a 3-wave longitudinal survey of community-dwelling older residents (n = 334) of Miami, Florida, we utilized generalized estimating equation models to examine the influence of changes in compassionate love (i.e., feeling love toward other persons and experiencing love from others) on depressive symptoms over time. We also explored cross-sectional relationship between compassionate love and positive and negative affects.
An increase in the feeling of being loved (β = -0.77, p < .001) and feeling love for others (β = -0.78, p < .001) led to a decline in odds of reporting greater levels of depressive symptoms over time. The odds of reporting higher level of positive affect were significantly greater for older adults who reported feeling loved by others (β = .63, p < .001) and expressed love for other people (β = 0.43, p < .05). Older adults who felt loved and expressed love for other people, respectively, had 0.71 and 0.54-point lower ordered log odds of reporting higher negative affect than those who reported lower levels of love. The statistically significant impact of feeling loved on all well-being outcomes was maintained even after adjustment for altruistic attitudes and emotional support. Except for depressive symptoms, such adjustments explained the positive influence of love for others on well-being outcomes.
Our findings underscore the powerful influence of both receiving and giving loving emotions for the maintenance of later-life psychological well-being.

The diverse range of presentations, presenting in distinct phenotypic waves, exemplified the importance of preparedness for the unknown. Lessons learned will be essential in planning for a likely second wave of SARS-CoV-2.
One of the hallmarks of myocardial infarction (MI) is excessive inflammation. During an inflammatory insult, damaged endothelial cells shed their glycocalyx, a carbohydrate-rich layer on the cell surface which provides a regulatory interface to immune cell adhesion. Selectin-mediated neutrophilia occurs as a result of endothelial injury and inflammation. We recently designed a novel selectin-targeting glycocalyx mimetic (termed DS-IkL) capable of binding inflamed endothelial cells. This study examines the capacity of DS-IkL to limit neutrophil binding and platelet activation on inflamed endothelial cells, as well as the cardio-protective effects of DS-IkL after acute myocardial infarction.
In vitro, DS-IkL diminished neutrophil interactions with both recombinant selectin and inflamed endothelial cells, and limited platelet activation on inflamed endothelial cells. Our data demonstrated that DS-IkL localized to regions of vascular inflammation in vivo after 45 minutes of left anterior descending coronary ajury induced by the immune response.
The coronavirus disease 2019 (COVID-19) pandemic resulted in social isolation globally, creating heightened levels of stress and anxiety. This study investigates the link between social isolation and mental well-being in later life, and how it varies across countries.
We draw on a subset of older adults from Global Behaviors and Perceptions in the COVID-19 Pandemic, a unique global online survey of 13,660 participants from 62 countries. We use mixed-effects models to analyze the data.
Social isolation (distancing) significantly predicts poor mental health operationalized as coronavirus-induced distress (p < .01). At the aggregate level, average distress varies positively across countries with higher numbers of coronavirus-related deaths (p < .10) and more fragile state capacity (p < .05), while varying negatively across those with more stringent anticoronavirus policies (p < .05). Finally, we report several cross-level interactions between social isolation and the total number of deaths (p = .025), policy stringency (p = .065), state fragility (p = .061), and globalization index (p = .071).
Our study shows that a proper understanding of the impact of COVID-19 on the mental well-being of older adults should consider the moderating role of national context.

Cytidine triphosphate (CTP) is at the crossroad of the processes allowing SARS-CoV-2 to multiply, because CTP is in demand for four essential metabolic steps. SBI-0640756 It is a building block of the virus genome, it is required for synthesis of the cytosine-based liponucleotide precursors of the viral envelope, it is a critical building block of the host transfer RNAs synthesis and it is required for synthesis of dolichol-phosphate, a precursor of viral protein glycosylation. The CCA 3'-end of all the transfer RNAs required to translate the RNA genome and further transcripts into the proteins used to build active virus copies is not coded in the human genome. It must be synthesized de novo from CTP and ATP. Furthermore, intermediary metabolism is built on compulsory steps of synthesis and salvage of cytosine-based metabolites via uridine triphosphate that keep limiting CTP availability. As a consequence, accidental replication errors tend to replace cytosine by uracil in the genome, unless recombination events allow the sequence to return to its ancestral sequences. We document some of the consequences of this situation in the function of viral proteins. This unique metabolic setup allowed us to highlight and provide a raison d'être to viperin, an enzyme of innate antiviral immunity, which synthesizes 3'-deoxy-3',4'-didehydro-CTP as an extremely efficient antiviral nucleotide.
