Hennepin County Adult Detention Center's Response to a 2019 Hepatitis A Outbreak in Minnesota.

Hennepin County Adult Detention Center (Jail) is Minnesota's largest jail. In August 2019, the Minnesota Department of Health declared a statewide hepatitis A outbreak. Within three days, Hennepin County Jail Health Services made significant changes to vaccination protocols that increased vaccination rates from 0.6% to 7.1% among detainees, who have a greater risk of contracting hepatitis A. We highlight the opportunity for jails to develop sustainable public health interventions in the setting of community outbreaks.

Prevalence of syphilis in female sex workers in three countryside cities of the state of Pará, Brazilian Amazon.

BACKGROUND: Syphilis is a sexually transmitted infection (STI) transmitted from person to person mainly by sexual intercourse or through vertical transmission during pregnancy. Female sex workers (FSWs) are exposed especially to syphilis infection, and besides all the efforts to control the spread of STIs, syphilis prevalence is still rising, mainly occurring in low-income countries. This study aimed to investigate the syphilis prevalence, demographic characteristics and sexual habits among FSWs in the Amazon region of Brazil. METHODS: A cross-sectional study was carried out including 184 FSWs from 3 countryside cities of the state of Pará, Amazon region of Brazil. A venereal disease research laboratory test and an indirect immunoenzyme assay to test antibodies against Treponema pallidum were used for screening syphilis infection, while sexual habits and demographic data information were collected through a semi-structured questionnaire. Data was analyzed comparing groups with/without syphilis. Poisson regression models were used to estimate the reasons of prevalence (RP). RESULTS: The overall prevalence of syphilis was 14.1% (95% CI = 9.8-17.8). FSWs had between 15 and 56 years of age, most were unmarried (65.7%), had attended less than 8 years of formal education (64.1%), had between 10 and 20 partners per week (64.1%), and reported no previous history of STIs (76.1%) and regular use of condom (52.7%). Low level of education attending up to the primary school (RP adjusted = 3.8; 95% CI = 1.4-9.2) and high frequency of anal sex during the past year (RP adjusted = 9.3; 95% CI = 3.5-28.7) were associated with a higher prevalence of syphilis. CONCLUSIONS: A high prevalence of syphilis among FSWs in the Brazilian Amazon region was identified, showing that syphilis is more likely to be transmitted in FSW working in low-income areas, which is attributed to the low level of education. Anal intercourse was found as a risk factor associated with syphilis. Health programs focused on risk populations appear as a rational way to control syphilis spread, which is a rising problem in Brazil and in other several countries.

Reversible, Selective Trapping of Perchlorate from Water in Record Capacity by a Cationic Metal-Organic Framework.

We report the capture of ppm-level aqueous perchlorate in record capacity and kinetics via the complete anion exchange of a cationic metal-organic framework. Ambient conditions were used for both the synthesis of silver 4,4'-bipyridine nitrate (SBN) and the exchange, forming silver 4,4'-bipyridine perchlorate (SBP). The exchange was complete within 90 min, and the capacity was 354 mg/g, representing 99% removal. These values are greater than current anion exchangers such as the resins Amberlite IRA-400 (249 mg/g), Purolite A530E (104 mg/g), and layered double hydroxides (28 mg/g). Moreover, unlike resins and layered double hydroxides, SBN is fully reusable and displays 96% regeneration to SBN in nitrate solution, with new crystal formation allowing the indefinite cycling for perchlorate. We show seven cycles as proof of concept. Perchlorate contamination of water represents a serious health threat because it is a thyroid endocrine disruptor. This noncomplexing anionic pollutant is significantly mobile and environmentally persistent. Removal of other anionic pollutants from water such as chromate, pertechnetate, or arsenate may be possible by this methodology.

DDIT4L regulates mitochondrial and innate immune activities in early life.

Pattern recognition receptor responses are profoundly attenuated before the third trimester of gestation in the relatively low-oxygen human fetal environment. However, the mechanisms regulating these responses are uncharacterized. Herein, genome-wide transcription and functional metabolic experiments in primary neonatal monocytes linked the negative mTOR regulator DDIT4L to metabolic stress, cellular bioenergetics, and innate immune activity. Using genetically engineered monocytic U937 cells, we confirmed that DDIT4L overexpression altered mitochondrial dynamics, suppressing their activity, and blunted LPS-induced cytokine responses. We also showed that monocyte mitochondrial function is more restrictive in earlier gestation, resembling the phenotype of DDIT4L-overexpressing U937 cells. Gene expression analyses in neonatal granulocytes and lung macrophages in preterm infants confirmed upregulation of the DDIT4L gene in the early postnatal period and also suggested a potential protective role against inflammation-associated chronic neonatal lung disease. Taken together, these data show that DDIT4L regulates mitochondrial activity and provide what we believe to be the first direct evidence for its potential role supressing innate immune activity in myeloid cells during development.

Global Is Local: Interprofessional Experiential Learning for Migrant Farmworker Health Equity.

Purpose: Medical educators recognize the importance of addressing social determinants of health and providing opportunities for learners to work with diverse populations. Still, social, geographic, resource, and language barriers prevent institutions from connecting with globally diverse populations within their own communities. In this article, we describe the migrant farmworker health course at the University of Minnesota, the importance of longitudinal partnership with community-based organizations, and ways to increase access to care and educate health professional learners in health equity. Methods: The migrant farmworker health course is a clinical rotation that combines didactic learning on social determinants of health with hands-on clinical experience. Learners work with community organizations to provide mobile health care while learning about a diverse and underserved rural population. Twenty-eight learners who participated in the course between 2015 and 2019 were surveyed about their experience, knowledge, and skills gained, and recommendations for improvement. Results: Over 90% of participants rated their overall experience in the course as "good" or "outstanding." Most learners increased confidence in the subjects that were covered during didactic sessions. Qualitative feedback provided insight on how the migrant farmworker health course shaped learners' understanding of social determinants of health and influenced their career trajectories. Conclusion: The migrant farmworker health course has educated interprofessional learners and is expanding to include more opportunities for mobile health care. The feedback from this survey helped improve didactic teaching and will help deepen relationships with community partners. Learning through service with global populations locally in a "global is local" rotation is a rewarding way to engage in and learn about health equity.

Impact of lockdown and unlocking on symptomatology and emergency department visits during the first wave of the COVID-19 pandemic.

Background: The COVID-19 pandemic resulted in a complete nationwide lockdown on March 24, 2020. The months of April and May had stringent lockdown measures followed by a gradual loosening of restrictions in a graded manner. Methods: This observational study was performed in the emergency department (ED) of a tertiary hospital in south India triage Priority 1 and Priority 2 patients presented during the COVID-19 lockdown and unlock periods spanning from April 2020 to August 2020. The three different lockdown periods and the subsequent unlock periods were categorized as lockdown 1 (LD1), lockdown 2 (LD2), lockdown 3 (LD3), and unlock phase (UL), and a 7-day time period in each were taken for 7-day incidence analysis. Results: During the 5-month study period, a total of 1,954 patients were analyzed for the study that included 405, 440, 492, and 617 patients during the 7-day time periods in the LD1, LD2, LD3, and UL periods, respectively. The 7-day incidence of COVID-19 suspects increased significantly by 101.9% from LD1 to UL phases, whereas trauma cases increased by 52.9% in the same two time periods. Compared with LD1, in the UL phase, the 7-day ED admission and in-hospital mortality rates increased by 50.3% and 66.7%, respectively. Conclusion: The number of COVID-19 suspects saw a near-constant increase through the different phases of lockdown, culminating in the UL phase. The stringent lockdown measures resulted in a significant reduction in the incidence of trauma with a rebound increase in the UL phase.

Dissociation of genotype-dependent cognitive and motor behavior in a strain of aging mice devoid of the prion protein.

The prion glycoprotein (PrPC) is highly expressed in the nervous system as well as in other organs. Its functional roles in behavior have been examined mainly in non co-isogenic, wild-type and PrPC-deficient mice, which showed both age- and genotype-dependent differences. In general, however, effects of genetic background upon behavioral tests are mostly unclear when applied to aging rodents. The present study aimed to determine the effect of deletion of the prion protein on behavior of isogenic mice across different ages. We disclosed a genotype-dependent behavioral dissociation between either motor or cognitive tests, as a function of both age and test type. Remarkably, we also detected a clear age- and genotype-dependent difference in the variability of performance in a cognitive test. The current findings are relevant for both the interpretation of PrPC-related behavior, as well as for issues of reproducibility in studies of rodent behavior.

Global Is Local: Does Formal Resident Global Health Medical Education Improve Clinical Care in the United States?

We administered a standardized 41-item questionnaire to a convenience sample of graduates of five residency programs with formal global health pathways and compared findings to a national cohort of practicing physicians to evaluate the comparative effectiveness of an overarching global health pathway on residency program graduates. Compared with the national cohort database, global health pathway graduates self-reported that they felt better prepared to treat immigrants, refugees, patients with limited English proficiency (LEP), racial/ethnic minorities, those with non-Western health beliefs, international travelers, and military veterans (P < 0.05). They were more likely to report using best practices when working with lesbian, gay, bisexual, transgender, queer/questioning patients, immigrant and refugee patients, patients with non-Western health beliefs, patients with LEP, and patients communicating via American Sign Language (P < 0.05). They also reported being more familiar with 11 of 14 high-impact or common infections encountered in travelers, immigrants, and military personnel (P < 0.05). Our findings suggest that formal postgraduate training focused on global health improves knowledge, attitudes, and self-reported medical practices when caring for diverse and marginalized populations in the United States.

Neonatal T Helper 17 Responses Are Skewed Towards an Immunoregulatory Interleukin-22 Phenotype.

Newborns are frequently affected by mucocutaneous candidiasis. Th17 cells essentially limit mucosal invasion by commensal Candida spp. Here, we sought to understand the molecular basis for the developmental lack of Th17 cell responses in circulating blood neonatal T cells. Naive cord blood CD4 T cells stimulated in Th17-differentiating conditions inherently produced high levels of the interleukin-22 immunoregulatory cytokine, particularly in the presence of neonatal antigen-presenting cells. A genome-wide transcriptome analysis comparing neonatal and adult naïve CD4 T cells ex vivo revealed major developmental differences in gene networks regulating Small Drosophila Mothers Against Decapentaplegic (SMAD) and Signal Transducer and Activator of Transcription 3 (STAT3) signaling. These changes were functionally validated by experiments showing that the requirement for TGF-ß in human Th17 cell differentiation is age-dependent. Moreover, STAT3 activity was profoundly diminished while overexpression of the STAT3 gene restored Th17 cell differentiation capacity in neonatal T cells. These data reveal that Th17 cell responses are developmentally regulated at the gene expression level in human neonates. These developmental changes may protect newborns against pathological Th17 cell responses, at the same time increasing their susceptibility to mucocutaneous candidiasis.

Inconsistent effects of gluten on obesity: is there a role for the haptoglobin isoforms?

BACKGROUND AND AIMS: There is no clear evidence about the effects of gluten intake on obesity. It is known that gluten's effects on gut permeability are mediated by zonulin, a protein identified as pre-haptoglobin 2, a physiological regulator of the intestinal barrier. We investigated the obesogenic and inflammatory effects of gluten and its association with the haptoglobin genotype. METHODS: This was a single blinded, crossover study, including 40 overweight or obesity women free of celiac disease. Participants adopted a gluten-free diet (GFD) for 8 weeks and consumed a gluten-free muffin (GF-M) or a gluten-containing muffin (GLU-M, 24 g gluten) for 4 weeks, switching muffin type during the subsequent 4 weeks. During a follow-up period of 4 weeks we evaluated the usual diet (UD). Food diaries were collected to estimate the macronutrient intake and dietary inflammatory index (DII®). Bodyweight and composition, resting energy expenditure (REE), and cytokines were assessed. Haptoglobin alleles (Hp1 and Hp2) were genotyped to characterize zonulin expression. RESULTS: Energy and macronutrient intakes were similar during both periods, except for protein intake, which was higher during GLU-M. DII scores indicated a more inflammatory profile during the GF-M and GLU-M periods compared to UD. No differences were observed in body composition or REE between interventions when the Hp genotype was not considered. Nonetheless, those carrying the Hp2-2 genotype (overexpressing zonulin) presented lower REE and higher levels of IL6 and IL1beta only during gluten intake (GLU-M and UD) compared to age- and body mass index-matched Hp1-1 carrier. These results suggest an obesogenic and inflammatory action of gluten only in those overexpressing zonulin (Hp2-2). CONCLUSION: These results highlight the importance of zonulin as the mediator of gluten obesogenic and inflammatory effects. Our data suggest that in the presence of gluten, zonulin release is associated with a reduction of REE and an increase of inflammatory markers that are not seen in zonulin low producers.

Molecular Epidemiology of HIV-1 and HTLV-1/2 Among Female Sex Workers in Four Cities in the State of Para, Northern Brazil.

Female sex workers (FSWs) represent a key population for the acquisition of sexually transmitted infections (STI) due to their social vulnerability and the risks associated with their occupation. This study was conducted to describe the sociodemographic characteristics and sexual behavior among FSWs in cities in northern Brazil, to determine the prevalence of human immunodeficiency virus 1 (HIV-1) and human T-cell lymphotropic virus (HTLV-1/2) infections and to identify the circulating subtypes of these agents in this key population. A cross-sectional study using the Time Location Sampling (TLS) method was conducted among 339 FSWs in cities in the state of Pará from 2005 to 2006. Serological and molecular tests were performed to identify infections and viral subtypes, and bivariate and multivariate analyses were conducted to identify risk factors. Most FSWs were young, single, less educated and had at least one child. The prevalence of antibodies against HIV-1 and HTLV-1 was 2.3 and 1.7%, respectively. HIV-1 subtypes B (87.5%) and F1 (12.5%) were identified among FSWs, as were Cosmopolitan subtype (1a) and Transcontinental subgroup (A). Unprotected sex and illicit drug use were associated with HIV-1 and HTLV-1 infections using bivariate and multivariate analyses, and age ≥27 years was associated only with HIV. The important information highlighted here clearly indicates that the lack of actions to control and prevent pathogens in FSWs and the lack of strategies for health promotion in key populations can further aggravate the epidemiological scenario of viral infections in remote areas with low human development indices. Neglecting these facts may be causing the spread of these two viruses and their respective subtypes in the general population of northern Brazil.

Neonatal infection leads to increased susceptibility to Aß oligomer-induced brain inflammation, synapse loss and cognitive impairment in mice.

Harmful environmental stimuli during critical stages of development can profoundly affect behavior and susceptibility to diseases. Alzheimer disease (AD) is the most frequent neurodegenerative disease, and evidence suggest that inflammatory conditions act cumulatively, contributing to disease onset. Here we investigated whether infection early in life can contribute to synapse damage and cognitive impairment induced by amyloid-ß oligomers (AßOs), neurotoxins found in AD brains. To this end, wild-type mice were subjected to neonatal (post-natal day 4) infection by Escherichia coli (1 × 104 CFU/g), the main cause of infection in low-birth-weight premature infants in the US. E. coli infection caused a transient inflammatory response in the mouse brain starting shortly after infection. Although infected mice performed normally in behavioral tasks in adulthood, they showed increased susceptibility to synapse damage and memory impairment induced by low doses of AßOs (1 pmol; intracerebroventricular) in the novel object recognition paradigm. Using in vitro and in vivo approaches, we show that microglial cells from E. coli-infected mice undergo exacerbated activation when exposed to low doses of AßOs. In addition, treatment of infected pups with minocycline, an antibiotic that inhibits microglial pro-inflammatory polarization, normalized microglial response to AßOs and restored normal susceptibility of mice to oligomer-induced cognitive impairment. Interestingly, mice infected with by E. coli (1 × 104 CFU/g) during adolescence (post-natal day 21) or adulthood (post-natal day 60) showed normal cognitive performance even in the presence of AßOs (1 pmol), suggesting that only infections at critical stages of development may lead to increased susceptibility to amyloid-ß-induced toxicity. Altogether, our findings suggest that neonatal infections can modulate microglial response to AßOs into adulthood, thus contributing to amyloid-ß-induced synapse damage and cognitive impairment.

Influence of the current density on the electrochemical treatment of concentrated 1-butyl-3-methylimidazolium chloride solutions on diamond electrodes.

This paper focuses on the influence of the current density treatment of a concentrated 1-butyl-3-methylimidazolium chloride (BMImCl) solution on an electrochemical reactor with a boron-doped diamond (BDD) anode. The decrease in the total organic carbon (TOC) and the BMImCl concentration demonstrate the capability of BDD in oxidizing ionic liquids (ILs) and further mineralizing (to CO2 and NO3 (-)) more rapidly at higher current densities in spite of the reduced current efficiency of the process. Moreover, the presence of Cl(-) led to the formation of oxychlorinated anions (mostly ClO3 (-) and ClO4 (-)) and, in combination with the ammonia generated in the cathode from the nitrate reduction, chloramines, more intensely at higher current density. Finally, the analysis of the intermediates formed revealed no apparent influence of the current density on the BMImCl degradation mechanism. The current density presents therefore a complex influence on the IL treatment process that is discussed throughout this paper.

Stress effects on rats chronically receiving a highly palatable diet are sex-specific.

The stress response is known to lead to behavioral and metabolic changes. Exposure to chronic stress can promote the development of physiological and behavioral dysfunctions, including alterations in feeding behavior. The aim of this study was to verify whether chronic restraint stress alters the consumption of a highly palatable, highly caloric diet (chocolate), chronically offered to the animals. Male rats ate more chocolate than females, and they also exhibited a higher weight gain, abdominal fat deposition, and higher plasma levels of total cholesterol, LDL-cholesterol and glucose. The stress exposure decreased body weight, increased adrenal weight and decreased plasma insulin levels. Overall, female rats had lower plasma insulin levels and chocolate consumption prevented the increased adrenal gland weight after exposure to chronic stress, suggesting a reduction of stress effects induced by palatable food consumption. Taken together, these results suggest a peculiar metabolic pattern, related to energy store and expenditure, in stressed animals receiving a palatable diet. Since these effects were sex-specific, we may also propose that females and males subjected to restraint stress and chocolate consumption are differentially affected.

Probióticos na terapia periodontal / Probiotics in the treatment of periodontal disease

A periodontite é causada por micro-organismos anaeróbicos Gram-negativos, que em um hospedeiro suscetível pode levar a destruição dos tecidos de suporte dos dentes. O tratamento da periodontite consiste no debridamento mecânico para eliminação dos patógenos. Entretanto, a recolonização ocorre em semanas e a instalação de uma microbiota mais patogênica ocorre em meses. Como as bactérias probióticas competem com as bactérias que causam injúrias à saúde, os probióticos passaram a ser cogitados como uma nova modalidade terapêutica no tratamento da doença periodontal. Os probióticos apresentam dois principais mecanismos de ação: um relacionado à colonização bacteriana e outro relacionado à modulação da resposta do hospedeiro.

Periodontitis is caused by Gram-negative anaerobic microorganisms, which in a susceptible host can lead to destruction of the supporting tissues of the teeth. Periodontitis treatment consists of mechanical debridement for removal of pathogens. However, recolonization occurs within weeks and the installation of a more pathogenic microbiota occurs in months. As probiotic bacteria compete with bacteria that cause injury to health, probiotics have been considered as a new therapeutic modality in the treatment of periodontal disease. Probiotics have two main mechanisms of action: one related to bacterial colonization and another related to the modulation of host response.
