    Abstract Purpose of the review: Regulatory B cells (Bregs) play a prominent role in various disease settings. While progress has been hindered by the lack of a specific Breg marker, new findings highlight their role modulating the alloimmune response and promoting allograft survival.
    Recent findings: Herein, we focus on the recent advances in Breg biology and their role in transplantation. We review studies showing that T-cell immunoglobulin and mucin domain 1 (TIM-1) is an inclusive and functional Breg marker in mice that may have human relevance. We highlight the utility of the B cell interleukin-10/tumor necrosis factor-alpha (IL-10/TNFα) ratio in identifying underlying immunological reactivity and predicting clinical outcomes in kidney transplantation. This may identify patients requiring more immunosuppression and provide insight into potential therapeutic approaches that can modulate the Breg: B effector cell (Beff) balance.
    Summary: Emerging data support Bregs as potent modulators of immune responses in humans. Their ability to promote allograft survival must await development of approaches to expand Bregs in vitro/in vivo . The low IL-10/TNFα ratio reflecting decreased Breg/Beff balance, predicts acute rejection (AR) and poorer outcomes in renal transplantation. It remains to be determined whether this paradigm can be extended to other allografts and whether therapy aiming to correct the relative deficiency of Bregs will improve outcomes.

  2. Article ; Online: Changes in ecosystem nutrient pools through stand development following whole-tree harvesting of jack pine (Pinus banksiana) on sandy, nutrient poor soils in northern Lower Michigan

    Abstract We used a 10-site, 42-year chronosequence of jack pine (Pinus banksiana) plantations to study the changes in ecosystem nutrient pools following whole-tree harvesting (WTH) on sandy soils. We developed locally-derived allometric equations to predict nutrient contents of jack pine as a function of diameter at breast height and used these to estimate the amount of nitrogen (N), calcium (Ca), potassium (K), magnesium (Mg), and phosphorus (P) stored in aboveground biomass. In addition, we quantified total N, Ca, K, Mg and P in surface organic horizons, plant-available nutrient pools in mineral soils and leaching losses of nutrients for four years post harvest. Finally, we constructed simple input–output nutrient balances accounting for harvest removals at varying ages, post-harvest leaching losses and nutrient inputs from atmospheric deposition and weathering under varying scenarios of harvest intensity and frequency. Nutrient accumulation in aboveground biomass followed a sigmoidal pattern with a period of rapid accumulation between ages 10–20 y, a period of slowing accumulation between 20 and 30 y to an apparent asymptote from 30 y onward. Our estimates of asymptotic aboveground nutrient stocks for these plantations were highest for N (263 kg ha⁻¹), intermediate for K and Ca (112 and 95 kg ha⁻¹) and lowest for Mg and P (22 and 17 kg ha⁻¹). Nutrients in forest floor materials increased from our youngest stand (4 y post harvest) with no signs of slowing accumulation in older stands. We observed weak trends of increasing soil nutrient availability across our chronosequence; however, variability was high both within and among stands. The business-as-usual scenario of WTH and planting on a 50-y rotation had a positive input–output balance for all nutrients with the exception of K, where outputs over this rotation exceeded inputs by 54 kg K ha⁻¹. Shifting to a bole-only harvest improved the nutrient balance for all elements considered and shifted K to a net positive balance of 32 kg K ha⁻¹. Scenarios designed to maximize production of biomass energy with WTH on shorter rotations exacerbated the K imbalance, with net losses of 72 and 63 kg K ha⁻¹ for 30- and 20-y rotations, respectively.

    Abstract Background: Pleural drainage following lung resection is almost universally practiced in pediatric surgery, but its necessity has been questioned in adult literature. We performed a cross-sectional study of pediatric patients undergoing lung resection to characterize chest tube (CT) practices and clarify their utility.
    Method: Retrospective chart review of patients <21 years of age undergoing pulmonary lobectomy or wedge resection at an academic children's hospital from 2013 to 2022. Variables regarding demographics and post-operative CT management were recorded.
    Results: 130 procedures meet inclusion criteria: 59 lobectomies (group 1), 19 diagnostic wedges (group 2), and 52 excisional wedges (group 3). 74.6% of group 1 patients had no air leak, and median CT duration was 2 days. In group 2, 89.5% had no air leak and median CT duration was 1 day. In Group 3, 80.8% had no air leak and median CT duration was 1 day. Overall, 43.1% patients had their CT removed on post-operative day 1 and 21.5% on post-operative day 2.
    Conclusion: CT duration following lung resection in pediatric patients is typically brief, with most patients having no air leak and CT removal within 2 days of surgery. Obligatory CT drainage may not be necessary in select patients undergoing lung resection.
    Level of evidence: Level IV.
    Type of study: Retrospective Study.

    Abstract Whereas the impacts of N deposition on forest ecosystems have been well studied in remote areas in predominantly forested landscapes, we know relatively less about the impacts of N deposition on forests in heavily human-modified landscapes. We studied the influence of adjacent land use, local point sources, and woodlot stand structure on subcanopy N transport and enrichment via throughfall in three woodlot fragments in southern Lower Michigan, USA. We found that one site had markedly higher TF N concentrations compared to the other two; however, our data indicate that elevated TF concentrations resulted from differences in tree species composition, rather than differences in surrounding land use. Specifically, we observed that the local abundance of basswood (Tilia americana) was positively associated and the local abundance of northern red oak (Quercus rubra) was negatively associated with TF N concentrations. One site had markedly greater TF N fluxes compared to the other two, which was driven by a lack of understory vegetation, possibly due to higher deer browsing at this site. Together, the results of this study demonstrated that TF N concentrations and fluxes were more strongly influenced by the internal characteristics of fragmented woodlots, such as forest structure and species composition, than by the surrounding land use.

    Abstract Rifamycins inhibit RNA polymerase of most bacterial genera. Rifampicin remains part of combination therapy for treating tuberculosis (TB), and for treating Gram-positive prosthetic joint and valve infections, in which biofilms are prominent. Rifabutin has use for AIDS patients in treating mycobacterial infections TB and Mycobacterium avium complex (MAC), having fewer drug-drug interactions that interfere with AIDS medications. Rifabutin is occasionally used in combination to eradicate Helicobacter pylori (peptic ulcer disease). Rifapentine has yet to fulfill its potential in reducing time of treatment for TB. Rifaximin is a monotherapeutic agent to treat gastrointestinal (GI) disorders, such as hepatic encephalopathy, irritable bowel syndrome, and travelers' diarrhea. Rifaximin is confined to the GI tract because it is not systemically absorbed on oral dosing, achieving high local concentrations, and showing anti-inflammatory properties in addition to its antibacterial activity. Resistance issues are unavoidable with all the rifamycins when the bioburden is high, because of mutations that modify RNA polymerase.

    Abstract Purpose: The purpose of this study was to examine motivations, fellowship experiences, and careers of graduates of the 10 accredited pediatric surgical critical care fellowships (PSCCF).
    Methods: Queries to PSCCF directors yielded a list of 86 graduates (2003-2013), each of whom received a 23-question survey.
    Results: Of the 86 graduates contacted, 82 (95.3%) replied. Among graduates who applied, 62 of 74 (83.8%) matched into pediatric surgery (PS) fellowships. On average, the respondents were 33 years old and PGY6 when beginning PSCCF. Half had failed initial attempts to match into PS fellowship. Of the matched respondents, 39 are pediatric surgeons and 21 PS fellows or residents awaiting fellowship. Two additional respondents did not complete fellowship. Among the pediatric surgeons, 13 identified their positions as heavily involved with critical care. The critical care boards pass rate was 94.4% (67/71). Rotations during fellowships were varied, with 74 fellows (90.2%) rotating in the pediatric intensive care unit (ICU), 71 (86.6%) in the neonatal ICU, 54 (65.9%) in the adult surgical ICU, and 36 (43.9%) on the pediatric surgical ward service.
    Conclusions: Completion of a PSCCF is highly predictive of a successful PS match. Only a third of PSCCF graduates continue critical care work in a formal fashion after PS fellowship.

    Abstract Objective: This study aimed to characterize risk factors for inpatient mortality in patients born with gastroschisis in a contemporary cohort.
    Study design: This was a retrospective cohort study of infants born with gastroschisis using the Kids' Inpatient Database 2016. Simple descriptive statistics were used to characterize the patients by demographics, and illness severity was estimated using the All-Patient Refined Diagnosis-Related Groups classification. Variables associated with an increased risk of mortality on univariate analysis were incorporated into a multivariable logistic regression model to generate adjusted odds ratios (aORs) for mortality.
    Results: An estimated 1,990 patient with gastroschisis were born in 2016, with a 3.7% mortality rate during the initial hospitalization. Multivariable logistic regression demonstrated the following variables to be associated with an increased risk of inpatient mortality: black or Asian race compared with white (aOR: 2.6, 95% confidence interval [CI]: 1.1-6.1,
    Conclusion: Inpatient mortality for neonates with gastroschisis is relatively low. Even after correcting for illness severity, race, health insurance status, and domicile appear to play a role in mortality disparities. Opportunities may exist to further decrease mortality in at-risk populations.

    Abstract In addition to their role in humoral immunity, B cells can exhibit regulatory activity. Such B cells have been termed regulatory B cells (Bregs). Bregs have been shown to inhibit inflammatory immune responses in a variety of autoimmune, alloimmune, and infectious settings. Breg activity is frequently IL-10-dependent, although a number of other mechanisms have been identified. However, our understanding of Bregs has been hampered by their rarity, lack of a specific phenotypic marker, and poor insight into their induction and maintenance.

    Abstract Regulatory B cells (Bregs) ameliorate autoimmune disease and prevent allograft rejection. Conversely, they hinder effective clearance of pathogens and malignancies. Breg activity is mainly attributed to IL-10 expression, but also utilizes additional regulatory mechanisms such as TGF-β, FasL, IL-35, and TIGIT. Although Bregs are present in various subsets defined by phenotypic markers (including canonical B cell subsets), our understanding of Bregs has been limited by the lack of a broadly inclusive and specific phenotypic or transcriptional marker. TIM-1, a broad marker for Bregs first identified in transplant models, plays a major role in Breg maintenance and induction. Here, we expand on the role of TIM-1
