Forensic sex estimation is a key component in attempts to identify human remains. The skull is often used for this purpose, but is often damaged or recovered in fragments. Studies of individual cranial bones are hampered by subjectivity in visual assessment and difficulties in the ability to capture complex shape variations, as well as accounting for population-specificity in the expression of sexual dimorphism. The present study employed geometric morphometric analysis to assess morphological variation of the occipital bones of 792 adult South African individuals. Though sexual differences in size were detected, shape dimorphism was not detected until ancestry was simultaneously accounted for. Female occipital bones were less robust but more sloped than those of males. Detected variation between ancestry groups was sufficient to produce approximately 80% classification accuracies for Black and White groups, and 74% for the highly heterogeneous Coloured group. When variation was assessed according to sex and ancestry simultaneously, groups could be distinguished with 74.8% accuracy. Shape variation showed no significant age or secular trend changes, though some weak positive allometric influence was detected in the variation between sexes and between the Coloured group and the other two ancestry groups. This study demonstrated that even isolated bones such as the occipital could be used for sex and ancestry estimation, though population differences must be considered. The geometric morphometric analysis was found to allow objective and sufficiently sensitive detection of variation in the complex occipital shape to allow for accurate distinction of even highly heterogeneous and closely related groups, even when using a limited number of cranial landmarks. Thus, similar analyses of the occipital may be employed in forensic cases where the cranium has been damaged or only the occipital bone is recovered and available for analysis.Immune checkpoint inhibitors enhance T cell response against malignant cells and are standard of care in many tumor types. Disinhibition of cytotoxic T cells in normal organs and inhibition of regulatory T cells can lead to immune-related adverse events. Here we describe a 60-year-old man with metastatic melanoma treated with three cycles of nivolumab and ipilimumab. He subsequently presented with new-onset brittle diabetes, rash, fever, and acute kidney injury. After initiation of insulin and aggressive fluid resuscitation, his kidney functions transiently improved but then dramatically worsened. Due concerns regarding hyperglycemia, a steroid-sparing agent was necessary and he was successfully treated with front-line mycophenolate mofetil, leading to normalization of renal function. The patient went on to develop a complete response and remains disease-free four years later. We conclude that mycophenolate can serve as an effective frontline therapy for immune-mediated acute kidney injury when steroids are contraindicated.
Epigenetic variation of DNA methylation of the mu-opioid receptor gene (
) has been identified in the blood and saliva of individuals with opioid use disorder (OUD) and infants with neonatal opioid withdrawal syndrome (NOWS). It is unknown whether epigenetic variation in
exists within placental tissue in women with OUD and whether it is associated with NOWS outcomes. In this pilot study, the authors aimed to 1) examine the association between placental
DNA methylation levels and NOWS outcomes, and 2) compare
methylation levels in opioid-exposed
non-exposed control placentas.

Placental tissue was collected from eligible opioid (
= 64) and control (
= 29) women after delivery. Placental DNA was isolated and methylation levels at six cytosine-phosphate-guanine (CpG) sites within the
promoter were quantified. Methylation levels were evaluated for associations with infant NOWS outcome measures need for pharmacologic treatment, length of hospital stay (LOS), morphine treatment days, and treaween OPRM1 placental DNA methylation levels and NOWS severity in this pilot cohort. In addition, no significant differences were seen in OPRM1 methylation in opioid versus control placentas. Future association studies examining methylation levels on a genome-wide level are warranted.Modelling of fields generated by therapeutic ultrasound arrays can be prone to errors arising from differences from nominal transducer parameters, and variations in relative outputs of array elements when driven under different conditions, especially when simulating steered fields. Here, the effect of element size, element positions, relative source pressure variations, and electrical crosstalk on the accuracy of modelling pressure fields generated by a 555 kHz 32-element ultrasonic array were investigated. For this transducer, errors in pressure amplitude and focal position were respectively reduced from 20% to 4% and 3.3 mm to 1.5 mm using crosstalk prediction, and experimentally determined positions.A randomized placebo-controlled trial by Martí et al.1 shows that probiotic supplementation of premature infants can modulate the infant gut microbiota soon after birth.Hantaviruses are zoonotic RNA viruses that cause severe acute disease in humans. CB-5083 molecular weight Infected individuals have strong inflammatory responses that likely cause immunopathology. Here, we studied the response of mucosal-associated invariant T (MAIT) cells in peripheral blood of individuals with hemorrhagic fever with renal syndrome (HFRS) caused by Puumala orthohantavirus, a hantavirus endemic in Europe. We show that MAIT cell levels decrease in the blood during HFRS and that residual MAIT cells are highly activated. This activation correlates with HFRS severity markers. In vitro activation of MAIT cells by hantavirus-exposed antigen-presenting cells is dependent on type I interferons (IFNs) and independent of interleukin-18 (IL-18). These findings highlight the role of type I IFNs in virus-driven MAIT cell activation and suggest a potential role of MAIT cells in the disease pathogenesis of viral infections.Single-cell RNA sequencing (scRNA-seq) is an evolving technology used to elucidate the cellular architecture of adult organs. Previous scRNA-seq on breast tissue utilized reduction mammoplasty samples, which are often histologically abnormal. We report a rapid tissue collection/processing protocol to perform scRNA-seq of breast biopsies of healthy women and identify 23 breast epithelial cell clusters. Putative cell-of-origin signatures derived from these clusters are applied to analyze transcriptomes of ~3,000 breast cancers. Gene signatures derived from mature luminal cell clusters are enriched in ~68% of breast cancers, whereas a signature from a luminal progenitor cluster is enriched in ~20% of breast cancers. Overexpression of luminal progenitor cluster-derived signatures in HER2+, but not in other subtypes, is associated with unfavorable outcome. We identify TBX3 and PDK4 as genes co-expressed with estrogen receptor (ER) in the normal breasts, and their expression analyses in >550 breast cancers enable prognostically relevant subclassification of ER+ breast cancers.Implementation of complete mesogastric excision in gastric cancer surgery, named D2 lymphadenectomy plus complete mesogastric excision (D2+CME), has recently been proposed as an optimal procedure. However, the safety and efficacy of D2+CME remain uncertain. In this randomized controlled trial, patients receiving D2+CME exhibit less intraoperative blood loss, more lymph node harvesting, and earlier postoperative flatus than patients receiving conventional D2 radical surgery. Univariate Cox regression analysis reveals that the risk ratio for postoperative flatus in D2+CME group is 1.247 (p = 0.044). Overall postoperative complications are comparable between the two groups, but complications are significantly less severe in the D2+CME group than the D2 group (Clavien-Dindo classification grade ≥ IIIa 4 D2+CME patients [11.8%] versus 9 D2 patients [33.3%]; p = 0.041). In conclusion, our work shows that D2+CME is associated with better short-term outcomes and surgical safety than conventional D2 dissection for patients with advanced gastric cancer.Cardiotoxicity, defined as toxicity that affects the heart, is one of the most common adverse drug effects. Numerous drugs have been shown to have the potential to induce lethal arrhythmias by affecting cardiac electrophysiology, which is the focus of current preclinical testing. However, a substantial number of drugs can also affect cardiac function beyond electrophysiology. Within this broader sense of cardiotoxicity, this review discusses the key drug-protein interactions known to be involved in cardiotoxic drug response. We cover adverse effects of anticancer, central nervous system, genitourinary system, gastrointestinal, antihistaminic, anti-inflammatory, and anti-infective agents, illustrating that many share mechanisms of cardiotoxicity, including contractility, mitochondrial function, and cellular signaling.Therapeutic vaccination regimens inducing clinically effective tumor-specific CD8+ T lymphocyte (CTL) responses are an unmet medical need. We engineer two distantly related arenaviruses, Pichinde virus and lymphocytic choriomeningitis virus, for therapeutic cancer vaccination. In mice, life-replicating vector formats of these two viruses delivering a self-antigen in a heterologous prime-boost regimen induce tumor-specific CTL responses up to 50% of the circulating CD8 T cell pool. This CTL attack eliminates established solid tumors in a significant proportion of animals, accompanied by protection against tumor rechallenge. The magnitude of CTL responses is alarmin driven and requires combining two genealogically distantly related arenaviruses. Vector-neutralizing antibodies do not inhibit booster immunizations by the same vector or by closely related vectors. Rather, CTL immunodominance hierarchies favor vector backbone-targeted responses at the expense of self-reactive CTLs. These findings establish an arenavirus-based immunotherapy regimen that allows reshuffling of immunodominance hierarchies and breaking self-directed tolerance for efficient tumor control.Interactions between B cells and CD4+ T follicular helper (Tfh) cells are key determinants of humoral responses. Using samples from clinical trials performed with the malaria vaccine candidate antigen Plasmodium falciparum merozoite protein (PfRH5), we compare the frequency, phenotype, and gene expression profiles of PfRH5-specific circulating Tfh (cTfh) cells elicited by two leading human vaccine delivery platforms heterologous viral vector prime boost and protein with AS01B adjuvant. We demonstrate that the protein/AS01B platform induces a higher-magnitude antigen-specific cTfh cell response and that this correlates with peak anti-PfRH5 IgG concentrations, frequency of PfRH5-specific memory B cells, and antibody functionality. Furthermore, our data indicate a greater Th2/Tfh2 skew within the polyfunctional response elicited following vaccination with protein/AS01B as compared to a Th1/Tfh1 skew with viral vectors. These data highlight the impact of vaccine platform on the cTfh cell response driving humoral immunity, associating a high-magnitude, Th2-biased cTfh response with potent antibody production.
