The lamina propria of the gastrointestinal tract and other mucosal surfaces of humans and mice host a network of mononuclear phagocytes that differ in their ontogeny, surface marker and transcription factor expression, and functional specialization. Conventional dendritic cells (DCs) in particular exist as two major subpopulations in both lymphoid and nonlymphoid organs that can be distinguished based on their surface marker and transcription factor expression. In this study, we show in various Th1- and/or Th17-polarized settings of acute and chronic bacterial infection and of tumor growth that the conditional ablation of Irf4 in CD11c+ DCs results in more efficient immune control of Helicobacter pylori, Mycobacterium bovis bacillus Calmette-Guérin, and Citrobacter rodentium and of tumor growth in a syngeneic tumor model. We attribute the phenotype of IRF4ΔDC mice to unrestricted Th1 responses and in particular to IFN-γ- and TNF-α-expressing CD4+ T cells. This activity of IRF4-expressing DCs is linked to a DC-specific immunoregulatory transcriptional program. In contrast, in Th2-polarized settings such as house dust mite-induced allergic airway inflammation, the lack of IRF4 expression in the DC compartment alleviates inflammation and goblet cell metaplasia. The combined data provide evidence for immunoregulatory properties of this versatile DC population in Th1-polarized infection settings.The complement system plays an important role in our innate immune system. Complement activation results in clearance of pathogens, immune complex, and apoptotic cells. The host is protected from complement-mediated damage by several complement regulators. Factor H (FH) is the most important fluid-phase regulator of the alternative pathway of the complement system. Heterozygous mutations in FH are associated with complement-related diseases such as atypical hemolytic uremic syndrome (aHUS) and age-related macular degeneration. We recently described an agonistic anti-FH mAb that can potentiate the regulatory function of FH. This Ab could serve as a potential new drug for aHUS patients and alternative to C5 blockade by eculizumab. However, it is unclear whether this Ab can potentiate FH mutant variants in addition to wild-type (WT) FH. In this study, the functionality and potential of the agonistic Ab in the context of pathogenic aHUS-related FH mutant proteins was investigated. The binding affinity of recombinant WT FH and the FH variants, W1183L, V1197A, R1210C, and G1194D to C3b was increased upon addition of the potentiating Ab and similarly, the decay-accelerating activity of all mutants is increased. The potentiating anti-FH Ab is able to restore the surface regulatory function of most of the tested FH mutants to WT FH levels on a human HAP-1 cell line and on sheep erythrocytes. In conclusion, our potentiating anti-FH is broadly active and able to enhance both WT FH function as well as most aHUS-associated FH variants tested in this study.
The increase in neonatal abstinence syndrome (NAS) has underscored the need for NAS surveillance programs, but many rely on passive surveillance using unverified diagnosis codes. Few studies have evaluated the validity of these codes, and no study has assessed the recently proposed Council of State and Territorial Epidemiologists (CSTE) case definition. The Florida Birth Defects Registry investigated the accuracy of
codes related to NAS (P96.1 and P04.49) and assessed the sensitivity of the CSTE case definition.

We identified a sample of infants born during 2016 coded with P96.1 and/or P04.49. Record review was completed for 128 cases coded with P96.1, 68 with P04.49, and 7 with both codes. Lacking consensus regarding a gold standard definition of NAS, we used clinical data to classify each case using the Florida and CSTE definitions. The code-specific accuracy was measured by using the positive predictive value (PPV). The clinical characteristics indicative of NAS were compared for case classification based on both definitions.

By using the Florida definition, the overall PPV was 68% but varied by code 95.3% for P96.1 and 13.2% for P04.49. The overall (47.8%) and code-specific PPVs were lower by using the CSTE definition. PMX 205 CD markers peptide Comparison of clinical characteristics demonstrated that 60.7% of cases classified as no NAS by using the CSTE definition had robust clinical signs of NAS. In our sample, the CSTE case definition underestimated NAS prevalence.

Only the P96.1
code displayed high accuracy. Discordance in NAS case definitions and surveillance methodologies may result in erroneous comparisons and conclusions that negatively impact NAS-related surveillance and research.
Only the P96.1 International Classification of Diseases, 10th Revision, Clinical Modification code displayed high accuracy. Discordance in NAS case definitions and surveillance methodologies may result in erroneous comparisons and conclusions that negatively impact NAS-related surveillance and research.
Preterm infants with necrotizing enterocolitis (NEC) are known to have worse neurodevelopmental outcomes, but there is no substantial evidence to support an underlying pathophysiology. We aimed to examine whether cerebral oxygenation differs in those infants who develop NEC compared to cerebral oxygenation in those who do not.

We examined 48 infants <30 weeks' gestation admitted to a tertiary level NICU from October 2016 to May 2018. Infants with birth weight less than or equal to the second percentile, abnormal antenatal dopplers or twin-to-twin-transfusion-syndrome were excluded. Cerebral oximetry measurements were performed by using a near-infrared spectroscopy (NIRS) monitor weekly for 60 minutes, allowing measurement of cerebral tissue oxygenation index from the first week of life to 36 weeks postconceptional age. Weekly clinical status was also recorded. NEC was defined as greater than or equal to Bell stage 2.

The median birth weight was 884 g (range of 460-1600 g), the median weeks' gestationneurodevelopmental outcome.
Previous studies have investigated the impact of preoperative hysteroscopy on the staging and survival of predominantly grade 1 endometrial cancers. We sought to evaluate the effect of hysteroscopy on the peritoneal spread of tumor cells and disease course in a large series of patients with high-risk endometrial cancer.

Patients who underwent hysterectomy for grade 3 endometrial carcinoma on final surgical pathology at the Mayo Clinic in Rochester, MN between January 2009 to June 2016 were included, noting hysteroscopy within 6 months from surgery. Intra-peritoneal disease was defined as any positive cytology OR adnexal invasion OR stage IV. The presence of intra-peritoneal disease OR peritoneal recurrence within 2 years from surgery was defined as peritoneal dissemination. Cox proportional hazards models were fit to evaluate associations between hysteroscopy exposure and progression within 5 years following surgery.

Among 831 patients, 133 underwent hysteroscopy. There was no difference in age, body mass index, ASA ≥3, or serous histology between patients who did or did not undergo hysteroscopy.
