Accumulating evidence indicates that cell death triggers sterile inflammation and that impaired clearance of dead cells causes nonresolving inflammation; however, the underlying mechanisms are still unclear. Here, we show that macrophage-inducible C-type lectin (Mincle) senses renal tubular cell death to induce sustained inflammation after acute kidney injury in mice. Mincle-deficient mice were protected against tissue damage and subsequent atrophy of the kidney after ischemia-reperfusion injury. Using lipophilic extract from the injured kidney, we identified β-glucosylceramide as an endogenous Mincle ligand. Notably, free cholesterol markedly enhanced the agonistic effect of β-glucosylceramide on Mincle. Moreover, β-glucosylceramide and free cholesterol accumulated in dead renal tubules in proximity to Mincle-expressing macrophages, where Mincle was supposed to inhibit clearance of dead cells and increase proinflammatory cytokine production. This study demonstrates that β-glucosylceramide in combination with free cholesterol acts on Mincle as an endogenous ligand to induce cell death-triggered, sustained inflammation after acute kidney injury.
Approximately 70% of women report experiencing vasomotor symptoms (VMS, hot flashes and/or night sweats). The etiology of VMS is not clearly understood but may include genetic factors.

We searched PubMed and Embase in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. We included studies on associations between genetic variation and VMS. We excluded studies focused on medication interventions or prevention or treatment of breast cancer.

Of 202 unique citations, 18 citations met the inclusion criteria. Study sample sizes ranged from 51 to 17 695. Eleven of the 18 studies had fewer than 500 participants; 2 studies had 1000 or more. Overall, statistically significant associations with VMS were found for variants in 14 of the 26 genes assessed in candidate gene studies. The cytochrome P450 family 1 subfamily A member 1 (CYP1B1) gene was the focus of the largest number (n = 7) of studies, but strength and statistical significance of associations of CYP1B1 variants with VMS were inconsistent. A genome-wide association study reported statistically significant associations between 14 single-nucleotide variants in the tachykinin receptor 3 gene and VMS. Heterogeneity across trials regarding VMS measurement methods and effect measures precluded quantitative meta-analysis; there were few studies of each specific genetic variant.

Genetic variants are associated with VMS. The associations are not limited to variations in sex-steroid metabolism genes. However, studies were few and future studies are needed to confirm and extend these findings.

The phoria adaptation task consisted of a block protocol of 90 seconds of near visual crossed fixation followed by 90 seconds of far visual uncrossed fixation, repeated three times; the data were collected during two different experimental sessions. Results showed that the oculomotor vermis, cuneus, and primary visual cortex had the greatest functional activity within the regions of interest studied when stimulated by the phoria adaptation task. The oculomotor vermis functional activity had an intraclass correlation coefficient (ICC) of 0.3, whereas the bilateral cuneus and primary visual cortex had good ICC results of greater than 0.6. These results suggest that the sustained visual fixation task described within this study reliably activates the neural substrates of phoria adaptation. This protocol establishes a methodology that can be used in future longitudinal studies investigating therapeutic interventions that may modify phoria adaptation.One to 2 pregnant women in 1000 will experience venous thromboembolism (VTE) during pregnancy or postpartum. Pulmonary embolism (PE) is a leading cause of maternal mortality, and deep vein thrombosis leads to maternal morbidity, with postthrombotic syndrome potentially diminishing quality of life for a woman's lifetime. However, the evidence base for pregnancy-related VTE management remains weak. Evidence-based guideline recommendations are often extrapolated from nonpregnant women and thus weak or conditional, resulting in wide variation of practice. In women with suspected PE, the pregnancy-adapted YEARS algorithm is safe and efficient, rendering computed tomographic pulmonary angiography to rule out PE unnecessary in 39%. Low molecular weight heparin (LMWH) in therapeutic doses is the treatment of choice during pregnancy, and anticoagulation (LMWH or vitamin K antagonists [VKAs]) should be continued until 6 weeks after delivery, with a 3-month minimum total duration. LMWH or VKA use does not preclude breastfeeding. Postpartum, direct oral anticoagulants are an option if a woman does not breastfeed and long-term use is intended. Management of delivery, including type of analgesia, requires a multidisciplinary approach and depends on local preferences and patient-specific conditions. Several options are possible, including waiting for spontaneous delivery with temporary LMWH interruption. Prophylaxis for recurrent VTE prevention in subsequent pregnancies is indicated in most women with a history of VTE.In correctly predicting that selection efficiency is positively correlated with the effective population size (Ne), the nearly neutral theory provides a coherent understanding of between-species variation in numerous genomic parameters, including heritable error (germline mutation) rates. Does the same theory also explain variation in phenotypic error rates and in abundance of error mitigation mechanisms? Translational read-through provides a model to investigate both issues as it is common, mostly nonadaptive, and has good proxy for rate (TAA being the least leaky stop codon) and potential error mitigation via "fail-safe" 3' additional stop codons (ASCs). Prior theory of translational read-through has suggested that when population sizes are high, weak selection for local mitigation can be effective thus predicting a positive correlation between ASC enrichment and Ne. Contra to prediction, we find that ASC enrichment is not correlated with Ne. ASC enrichment, although highly phylogenetically patchy, is, however, more common both in unicellular species and in genes expressed in unicellular modes in multicellular species. By contrast, Ne does positively correlate with TAA enrichment. These results imply that local phenotypic error rates, not local mitigation rates, are consistent with a drift barrier/nearly neutral model.
Survivors of childhood acute myeloid leukemia (AML) are vulnerable to medical late-effects of treatment; however, less is known about their psychosocial outcomes. This study evaluated neurocognitive and psychosocial outcomes in long-term AML survivors treated with bone marrow transplantation (BMT) or intensive chemotherapy without BMT (IC).

AML survivors (N = 482; median age at diagnosis=8 [range=0-20] years; median age at evaluation=30 [range=18-49] years) treated with BMT (N = 183) or IC (N = 299) and sibling controls (N = 3190; median age at evaluation=32 [range=18-58] years) from the Childhood Cancer Survivor Study were compared on emotional distress (Brief Symptom Inventory-18), neurocognitive problems (CCSS Neurocognitive Questionnaire), Health-related Quality of Life (SF-36) and social attainment. selleck inhibitor Outcomes were dichotomized (impaired vs. non-impaired) using established criteria, and relative risks (RRs) were estimated with multivariable Poisson regression, adjusted for age-at-evaluation and sex.

AML survivors were more likely than siblings to report impairment in overall emotional (RR = 2.19, 95% CI = 1.51 to 3.18), neurocognitive (RR = 2.03, 95% CI = 1.47 to 2.79), and physical quality of life (RR = 2.71, 95% CI = 1.61 to 4.56) outcomes. Survivors were at increased risk for lower education (RR = 1.15, 95% CI = 1.03 to 1.30), unemployment (RR = 1.41, 95% CI = 1.16 to 1.71), lower income (RR = 1.39, 95% CI = 1.17 to 1.65) and not being married/partnered (RR = 1.33, 95% CI = 1.17 to 1.51). BMT-treated survivors did not differ statistically significantly from IC-treated on any outcome measure.

AML survivors are at increased risk for psychosocial impairment compared to siblings; however, BMT does not confer additional risk for psychosocial late-effects compared to treatment without BMT.

Cancer patients are uniquely vulnerable to COVID-19 and many have been or will be infected. Although an unfortunate minority will die from the infection, most will recover. This poses a challenge in which clinicians must weigh the benefits of initiation or resumption of antineoplastic therapy against the risks that antineoplastic treatment may worsen outcomes related to COVID-19 infection. A recent study of 423 patients at our institution found that patients in active cancer treatment who develop COVID-19 infection did not fare any worse than other hospitalized patients yet guidance as to who requires testing prior to antineoplastic therapy and when to resume therapy post-COVID diagnosis remains unknown. Our institution, therefore, commissioned a task force to help create guidelines for treating oncologists using available published literature. The taskforce focused on the ambulatory care testing guidelines only, as all inpatients receiving antineoplastic therapy are tested for COVID-19 prior to hospital admission. The guidelines focus solely on the safety and well-being of the individual patient undergoing antineoplastic therapy and are not designed to address infection control issues.The orb-weaver spiders Eustala oblonga (Chickering) and Eustala illicita (O. Picard-Cambridge) (Araneae Araneidae) inhabit the ant-defended acacias Vachellia melanocerus (Beurling) and Vachellia collinsii (Safford) (Fabales Fabaceae), respectively, in Panama. These spiders do not capture patrolling Pseudomyrmex ants but exploit their plant-protection services to escape predation. What effect the spiders have on the ant-acacia mutualisms is unknown. They may provide an additional layer of plant defense by capturing flying herbivorous insects in their webs. Alternatively, the spiders may disrupt the ant-acacia mutualisms by capturing alate acacia ants during nuptial flights. We evaluated these two hypotheses by sampling insects flying through acacia foliage and by identifying prey remains in webs. The proportions of insects captured on sticky card traps and in webs varied with taxonomic order and ecological role. Herbivorous insects greatly outnumbered other groups captured on sticky cards and were captured in spiders' webs in both acacia species but made up a minority of prey remains in webs.
