A Gradient of Hippocampal Inputs to the Medial Mesocortex

Memory-guided decisions depend on complex, finely tuned interactions between hippocampus and medial mesocortical regions anterior cingulate and retrosplenial cortices. The functional circuitry underlying these interactions is unclear. Using viral anatomical tracing, in vitro and in vivo electrophysiology, and optogenetics, we show that such circuitry is characterized by a functional-anatomical gradient. While CG receives excitatory projections from dorsal-intermediate CA1 originated exclusively in stratum pyramidale, retrosplenial cortex also receives inputs originating in stratum radiatum and lacunosum-moleculare, including GAD+ neurons providing long-range GABAergic projections. Such hippocampal projections establish bona fide synapses throughout cortical layers, with retrosplenial cortex densely targeted on its layer 3, around which it receives a combination of inhibitory and excitatory synapses. This gradient is reflected in the pattern of spontaneous oscillatory synchronicity found in the awake-behaving animal, compatible with the known functional similarity of hippocampus with retrosplenial cortex, which contrasts with the encoding of actions and “task-space” by cingulate cortex. Highlights Both MMC regions CG and RSC receive monosynaptic connections from the dorsal-intermediate CA1 CG receives layer-sparse excitatory projections exclusively originated from stratum piramidale whereas RSC is targeted densely in superficial layers by a mixed excitatory and inhibitory input originating from all CA1 strata CA1 monosynaptic projections correspond to active synapses onto distinct layers of the two MMC regions Diverse synchrony between MMC and HIPP recorded in vivo is consistent with the rostro-caudal diversity of direct HIPP-MMC connections
Associations of nutrient intakes with glaucoma among Japanese Americans

Abstract The aim of this study was to investigate possible associations of nutrient intake on glaucoma in subjects of Japanese descent living in Los Angeles, CA. In this cross-sectional study, 581 Japanese American participants in Los Angeles underwent an interview, fundus photography, comprehensive physical, and blood examinations, along with determining the body mass index status and any confounding factors. CDSketch was used to measure the cup-disc ratio and rim width of each fundus in the retinal photographs. A multivariate logistic regression test with adjustment for confounding factors was used to assess the association between glaucoma and nutrient intake. A total of 61 of 581 participants were diagnosed with glaucoma in this study. Multivariate logistic regression analysis showed that a high intake of iron (odds ratio [OR]: 1.303, P = .004), low intake of vitamin A (OR: 0.365, P = .019), and vegetable fat (OR: 0.957, P = .004) were associated with an increased risk of glaucoma. Current findings showed that high iron intake and low vitamin A and vegetable fat intake appeared to be associated with an increased risk of glaucoma in subjects of Japanese descent living in the Los Angeles populations.
Boron-Catalyzed N-Alkylation of Arylamines and Arylamides with Benzylic Alcohols.

A sustainable boron-based catalytic approach for chemoselective N-alkylation of primary and secondary aromatic amines and amides with primary, secondary, and tertiary benzylic alcohols have been presented. The metal-free protocol operates at low catalyst loading, tolerates several functional groups and generates H2O as the sole by-product. Preliminary mechanistic studies were performed to demonstrate the crucial role of boron catalyst for the activation of the intermediate dibenzyl ether and to identify the rate-determining step.
Breastmilk Lipids and Oligosaccharides Influence Branched Short Chain Fatty Acid Concentrations in Infants with Excessive Weight Gain.

SCOPE We aimed to identify breastmilk components associated with fecal concentration of SCFAs and to investigate whether they differ between infants with high weight gain (HW) and normal weight gain (NW). METHODS AND RESULTS Breastmilk and fecal samples were collected from mother-infant dyads with HW (n = 11) and NW (n = 15) at 5 and 9 months of age. Breastmilk was profiled using an untargeted method on UPLC-qTOF-MS. Fecal SCFAs were quantified using an isotope-labeled chemical derivatization method. Human milk oligosaccharides (HMOs) were quantified using HPLC after fluorescent derivatization. We found lower levels of α-linolenic acid, oleic acid, 3-oxohexadecanoic acid, LPE (P-16:0), LPC (16:0), LPC (18:0), PC (36:2) in breastmilk from mothers from the HW-group at 5 months of age. Fecal SCFA concentrations were increased during the transition period from breastfeeding to complementary feeding. Fecal butyrate concentration was higher in the NW-group at 9 months of age. Fecal branched SCFAs were positively associated with breastmilk phospholipid levels, free-fatty acid levels, HMO-diversity, sialylated-HMOs, 6'-sialyllactose, and disialyl-lacto-N-hexaose. CONCLUSION Fecal branched SCFA concentrations seem to be affected by breastmilk lipid and HMO composition. These differences in breastmilk phospholipids, α-linolenic acid, and specific HMO structures may partially explain the excessive weight gain in early life. This article is protected by copyright.

Radiological Evaluation of a Preoperative First Metatarsal Realignment Test for Metatarsus Primus Varus and Hallux Valgus Correction by the Syndesmosis Procedure

Background: Metatarsus primus varus correction is one of the primary surgical objectives for hallux valgus correction. Some soft tissue procedures have shown that the first metatarsal can be adequately realigned without osteotomy. The hypothesis of this study was that this correctability should also be demonstrable preoperatively. The purpose of this study was to assess whether a simple forefoot taping technique could do so and whether it could also be correlated with operative results after the syndesmosis procedure. Methods: Between May 2014 and December 2015, 147 feet with hallux valgus from 85 patients with an average age of 46.2 years underwent the syndesmosis procedure. All were followed prospectively with standing radiographic assessment of their first intermetatarsal angle, metatarsophalangeal angle, and medial sesamoid position preoperatively without and with a forefoot wrapping technique and postoperatively at 10 days, 6 months, and 1 year. Results: Their average preoperative intermetatarsal angle was reduced from 14.4 to 8.4 degrees by the wrapping technique, and their average metatarsophalangeal angle was spontaneously reduced from 31.8 to 21.8 degrees. After a minimum 1-year follow-up, they stabilized at 7.4 and 18.6 degrees, respectively. There was significant correlation between hallux valgus and metatarsus primus varus corrections by both forefoot wrapping and surgical methods with Spearman’s rank correlation of metatarsophalangeal angle and intermetatarsal angle corrections (r = 0.6077, P < .0001 due to the wrapping method; r = 0.7157, P < .0001 due to the syndesmosis procedure). All raw working radiographic images for this study can be viewed in the Supplemental Material section. Conclusion: This study found that a simple forefoot tape-wrapping technique could be used preoperatively to verify first metatarsal mobility for metatarsus primus varus correction by the soft tissue syndesmosis procedure without osteotomies. Level of Evidence: Level II, prospective comparative study.
Clinical Performance of Non-Carious Cervical Restorations Restored with the "Sandwich Technique" and Composite Resin: A Systematic Review and Meta-analysis.

PURPOSE To compare the retention rates of non-carious cervical restorations (NCCLs) constructed using the sandwich technique (a lining of glass-ionomer cement [GIC] or resin-modified glass-ionomer cement [RMGIC] and composite resin [CR]) with CR-only restorations. MATERIALS AND METHODS The search was performed in various databases, including the Cochrane Library, PubMed, Scopus, and Web of Science. Gray literature was inspected, as were ongoing and unpublished abstracts from the IADR (1990-2017). Study quality was evaluated using the Cochrane Collaboration bias risk tool. Data from primary and secondary outcomes were meta-analyzed at 1-, 2- and 3-year follow-ups using the random effects model. The quality of the body of evidence was assessed using the GRADE approach. RESULTS Initially, a total of 3645 articles were selected. After selection by titles, abstracts, and full texts, 6 articles were retrieved, but three were follow-ups of the same RCT. Therefore, a total of four studies remained for analysis. All studies were at unclear risk for bias. Among all outcomes, only loss of retention was lower for the sandwich technique at the 3-year follow-up (risk ratio [RR]: 7.5; 95% CI: 2.1 to 27.2; p = 0.002). CONCLUSIONS Based on the limited number of available studies, higher retention rates in NCCL restorations were observed with the sandwich technique compared to CR-only restorations at the 3-year follow-up. Secondary outcomes were not influenced by the restorative technique. Except for retention rates, which were of moderate quality, the evidence quality of all secondary outcomes was low.
Evaluation of the public health risk for autochthonous transmission of mosquito‐borne viruses in southern Switzerland

Epidemics of mosquito‐borne diseases such as chikungunya and dengue fever are becoming more frequent around the world. In Switzerland, autochthonous cases have not been reported so far, although the presence of the vector Aedes albopictus in urban areas of southern Switzerland increases the risk of indigenous transmissions subsequent to imported cases. In 2018, the potential risk of an outbreak of arboviral diseases was assessed in five municipalities of southern Switzerland. The population abundance of Ae. albopictus was evaluated during the mosquito active season by the mean number of Ae. albopictus bites per day per person (estimated using the human landing collection method) and the risk of outbreak in the case of the introduction of chikungunya, dengue or Zika viruses was estimated. In the five localities investigated, no epidemic risk appeared to be present for any of the arboviruses taken into consideration in the initial months (i.e. mid‐May to end of July) of Ae. albopictus activity. In the case of the introduction of chikungunya (mutated or not), dengue (serotype 1) or Zika (African lineage) viruses during mid‐end August, an epidemic could have occurred in all the municipalities investigated. In mid‐end September, the introduction of same arboviruses could have led to an epidemic in three of the five municipalities investigated.
Highly Porous Polymer-Derived Bioceramics Based on a Complex Hardystonite Solid Solution

Highly porous bioceramics, based on a complex hardystonite solid solution, were developed from silicone resins and micro-sized oxide fillers fired in air at 950 °C. Besides CaO, SrO, MgO, and ZnO precursors, and the commercial embedded silicone resins, calcium borate was essential in providing the liquid phase upon firing and favouring the formation of an unprecedented hardystonite solid solution, corresponding to the formula (Ca0.70Sr0.30)2(Zn0.72Mg0.15Si0.13) (Si0.85B0.15)2O7. Silicone-filler mixtures could be used in the form of thick pastes for direct ink writing of reticulated scaffolds or for direct foaming. The latter shaping option benefited from the use of hydrated calcium borate, which underwent dehydration, with water vapour release, at a low temperature (420 °C). Both scaffolds and foams confirmed the already-obtained phase assemblage, after firing, and exhibited remarkable strength-to-density ratios. Finally, preliminary cell tests excluded any cytotoxicity that could be derived from the formation of a boro-silicate glassy phase.
Correlation between FAS single nucleotide polymorphisms and breast carcinoma susceptibility in Asia

Abstract Background: FAS cell surface death receptor (FAS) gene has 2 common single nucleotide polymorphisms (SNPs) in its promoter, FAS-1377G > A (rs2234767) and FAS-670A > G (rs1800682). Several studies have investigated the role of these 2 polymorphisms in etiology of breast cancer in Asian population while the outcomes are inconsistent. To derive a more precise assessment of the association between breast cancer susceptibility with FAS gene promoter SNPs, a meta-analysis of published studies was performed. Material and methods: We systematically searched PubMed, Embase, Web of Science, and the Chinese biomedical database (CBM) for papers published until November 1, 2018. Odds ratio (OR) with 95% confidential interval (95%CI) was conducted to evaluate the associations. Statistical analysis was conducted using Stata13.0 software. A total of 8 studies covering 2564 cases and 2633 controls were included. Results: The integrated results suggest the following: For the FAS-1377G/A polymorphism, we only found significant associations for allele G vs allele A (OR = 1.100, 95%CI = 1.004–1.206, P = .040). After stratification by ethnicity, a significant association was observed only for the AA+GA vs GG genotype in East Asian populations (OR = 1.177, 95% CI = 1.010–1.371, P = .037). The association was not found in West Asian populations. For the FAS -670A/G polymorphism, no association with cancer risk was found in any comparison model. Sensitivity analysis suggests that the meta-analysis results obtained after excluding any single study were similar to the original ones, suggesting that the meta-analysis results were not significantly affected by any single study. Conclusion: These results indicated that FAS-1377G/A polymorphism may contribute to the increased breast cancer susceptibility and could be a promising target for cancer risk prediction. Further studies are needed to determine if the FAS gene confers a risk of breast cancer in other ethnic groups, such as Africans and Latin Americans.
Nursing care for renal patients on hemodialysis: challenges, dilemmas and satisfactions.

OBJECTIVE To identify the challenges, dilemmas and satisfactions presented by nursing professionals in hemodialysis services during the care of renal patients. METHOD Institutional ethnography was used, and 18 semi-structured interviews were conducted with nine members of the nursing staff. Conventional content analysis was performed. RESULTS For the nursing staff, care presents challenges such as the complex physical and emotional condition of patients, the management of technology for care, and coping with the suffering and death of patients with whom they have established a close relationship. The dilemmas are related to providing care for patients who refuse to receive it, and the personal and family costs involved in treatment in contrast to the limited quality of life of some patients. The main satisfactions are collaborative work, the sufficiency of resources and the confidence and recognition for performing independent work. CONCLUSION The findings of the study are associated with the presence of professional burnout and interference in the ability to build satisfactory interpersonal relationships, lower job satisfaction and quality of care.
Helicobacter pylori Infections in the Bronx, New York: Surveying Antibiotic Susceptibility and Strain Lineage by Whole-Genome Sequencing

The emergence of drug resistance in Helicobacter pylori has resulted in a greater need for susceptibility-guided treatment. While the alleles associated with resistance to clarithromycin and levofloxacin have been defined, there are limited data regarding the molecular mechanisms underlying resistance to other antimicrobials. Using H. pylori isolates from 42 clinical specimens, we compared phenotypic and whole-genome sequencing (WGS)-based detection of resistance. ABSTRACT The emergence of drug resistance in Helicobacter pylori has resulted in a greater need for susceptibility-guided treatment. While the alleles associated with resistance to clarithromycin and levofloxacin have been defined, there are limited data regarding the molecular mechanisms underlying resistance to other antimicrobials. Using H. pylori isolates from 42 clinical specimens, we compared phenotypic and whole-genome sequencing (WGS)-based detection of resistance. Phenotypic resistance correlated with the presence of alleles of 23S rRNA (A2142G/A2143G) for clarithromycin (kappa coefficient, 0.84; 95% confidence interval [CI], 0.67 to 1.0) and gyrA (N87I/N87K/D91Y/D91N/D91G/D99N) for levofloxacin (kappa coefficient, 0.90; 95% CI, 0.77 to 1.0). Phenotypic resistance to amoxicillin in three isolates correlated with mutations in pbp1, pbp2, and/or pbp3 within coding regions near known amoxicillin binding motifs. All isolates were phenotypically susceptible to tetracycline, although four bore a mutation in 16S rRNA (A926G). For metronidazole, nonsense mutations and R16H substitutions in rdxA correlated with phenotypic resistance (kappa coefficient, 0.76; 95% CI, 0.56 to 0.96). Previously identified mutations in the rpoB rifampin resistance-determining region (RRDR) were not present, but 14 novel mutations outside the RRDR were found in rifampin-resistant isolates. WGS also allowed for strain lineage determination, which may be important for future studies in associating precise MICs with specific resistance alleles. In summary, WGS allows for broad analyses of H. pylori isolates, and our findings support the use of WGS for the detection of clarithromycin and levofloxacin resistance. Additional studies are warranted to better define mutations conferring resistance to amoxicillin, tetracycline, and rifampin, but combinatorial analyses for rdxA gene truncations and R16H mutations have utility for determining metronidazole resistance.
SUSTAINED VIROLOGIC RESPONSE RATE IN CHRONIC HEPATITIS C PATIENTS THROUGH DIRECT-ACTING ANTIVIRALS THERAPY.

BACKGROUND In recent years the management of hepatitis C virus infection and the possibility of its eradication have been researched due to the importance that they represent in the health of the world population. Obtaining data that help to cope with this pathology improves the quality of life of those affected by it. The present study evaluated the effectiveness of direct-acting antiviral therapies provided by the Brazilian Ministry of Health in accordance to the Clinical Protocol and Therapeutic Guidelines of 2015. OBJECTIVE To evaluate the epidemiological profile of patients with chronic hepatitis C and the rate of sustained virologic response using direct-acting antivirals of all individuals that attended the referral service for the treatment of chronic hepatitis C at the Hospital of the Federal University of Rio Grande. METHODS This was an observational, retrospective/prospective study with all patients with chronic hepatitis C who had their treatments available from December 2015 to August 2017 according to the criteria of the Clinical Protocol and Therapeutic Guidelines of 2015. In the first phase, the clinical and demographic variables of all individuals enrolled in a treatment for hepatitis C were selected and collected from the Reference Service database. In the second phase, treatment data were collected. The outcome variable, sustained virologic response, was defined as an undetectable viral load on the blood test three months after the end of treatment. The descriptive and bivariate analyzes were performed with Pearson's chi-square and Fisher's Exact test, adopting a P value ≤0.05 in the SPSS 20 software. RESULTS Of the 252 participants in the study, 228 (90.5%) had a sustained virologic response, 55.2% were male with an average age of 58.6 years (SD±9.1). Genotype 1 was the most prevalent, observed in 54.4% of the participants, and 87.4% of the patients had moderate/advanced hepatic fibrosis. After the statistical analysis, it was observed that the individuals with genotype 3 and moderate/advanced hepatic fibrosis had lower sustained virologic response rate (P=0.05 and P=0.04, respectively). CONCLUSION It was observed that the use of direct-acting antivirals, in comparison to previous therapeutic regimens, increases the sustained virologic response, reaching all patients with mild fibrosis. This study provides information that helps in the hepatitis C treatment by showing that prescribing early treatment for patients without hepatic fibrosis and/or genotype 3 virus could increase therapeutic effectiveness.
Effects of hospital-acquired pneumonia on long-term recovery and hospital resource utilization following moderate to severe traumatic brain injury

Supplemental digital content is available in the text. BACKGROUND Individuals with traumatic brain injury (TBI) have extended inpatient hospital stays that include prolonged mechanical ventilation, increasing risk for infections, including pneumonia. Studies show the negative short-term effects of hospital-acquired pneumonia (HAP) on hospital-based outcomes; however, little is known of its long-term effects. METHODS A prospective cohort study was conducted. National Trauma Databank and Traumatic Brain Injury Model Systems were merged to derive a cohort of 3,717 adults with moderate-to-severe TBI. Exposure data were gathered from the National Trauma Databank, and outcomes were gathered from the Traumatic Brain Injury Model Systems. The primary outcome was the Glasgow Outcome Scale—Extended (GOS-E), which was collected at 1, 2, and 5 years postinjury. The GOS-E was categorized as favorable (>5) or unfavorable (≤5) outcomes. A generalized estimating equation model was fitted estimating the effects of HAP on GOS-E over the first 5 years post-TBI, adjusting for age, race, ventilation status, brain injury severity, injury severity score, thoracic Abbreviated Injury Scale score of 3 or greater, mechanism of injury, intraventricular hemorrhage, and subarachnoid hemorrhage. RESULTS Individuals with HAP had a 34% (odds ratio, 1.34; 95% confidence interval, 1.15–1.56) increased odds for unfavorable GOS-E over the first 5 years post-TBI compared with individuals without HAP, after adjustment for covariates. There was a significant interaction between HAP and follow-up, such that the effect of HAP on GOS-E declined over time. Sensitivity analyses that weighted for nonresponse bias and adjusted for differences across trauma facilities did not appreciably change the results. Individuals with HAP spent 10.1 days longer in acute care and 4.8 days longer in inpatient rehabilitation and had less efficient functional improvement during inpatient rehabilitation. CONCLUSION Individuals with HAP during acute hospitalization have worse long-term prognosis and greater hospital resource utilization. Preventing HAP may be cost-effective and improve long-term recovery for individuals with TBI. Future studies should compare the effectiveness of different prophylaxis methods to prevent HAP. LEVEL OF EVIDENCE Prospective cohort study, level III.
Meditation effect on psychological stress level in women with breast cancer: a systematic review.

OBJECTIVE To evaluate the effect of meditation on the psychological stress level of women with breast cancer. METHOD A systematic literature review performed in the LILACS, PubMed, Scopus, CINAHL and Web of Science databases. RESULTS The sample consisted of 22 studies using Mindfulness, Transcendental Meditation, and Contemplative Self-Healing Meditation techniques. There was a significant effect of meditation on stress reduction, post-traumatic stress symptoms, self-reported stress, and chronic stress verified. In some studies, the effect was associated with decreased cortisol and increased telomerase. CONCLUSION Meditation has shown positive effects in reducing physical and emotional symptoms such as psychological stress, depression, anxiety, fatigue, fear of recurrence and rumination, representing an efficient strategy for coping with the disease and improving quality of life.
