Maternal and Early Postnatal Diet Supplemented with Conjugated Linoleic Acid Isomers Affect Lipid Profile in Hearts of Offspring Rats with Mammary Tumors

Simple Summary Proper feeding during pregnancy and breastfeeding plays an important role in ensuring the health of offspring in childhood as well as in adulthood. The idea of the “developmental origin of health and disease” (DOHaD) assumes that stimuli acting during fetal life cause long-term developmental and physiological changes in the main organs and influence the risk of many diseases. Our research, connected with DOHaD, made an attempt to evaluate the impact of the diet modification of mothers through the addition of conjugated linoleic acid isomers (CLA) on the lipid profile, fatty acid profile and the oxidative stress in the hearts of offspring with breast cancer. Earlier studies utilizing CLA in DOHaD concerned their impact on reducing the incidence of cancer. Considering reports on the co-occurrence of cardiovascular diseases (CVD) in oncological patients as a result of tumor development and also after chemotherapy and radiotherapy, further research is needed to assess the potential protective effect of CLA isomers in CVD. For this purpose, the content of selected CVD biomarkers was determined using modern analytical techniques. Our research has tried to explain the physiological role of CLA and its mechanism of action in the context of maintaining good health and in the prevention of non-communicable diseases. Abstract Linking the early life environment with later health status is known as “developmental programming”. This study aimed to assess whether the introduction of conjugated linoleic acids (CLAs) into the maternal diet affects the content fatty acids (FAs), conjugated FAs (CFAs), cholesterol, oxysterols, malondialdehyde (MDA) and tocopherols in the hearts of their female offspring treated with 7,12-dimethylbenz[a]anthracene and if offspring supplementation enhanced the effect of maternal supplementation. FA, cholesterol and oxysterol contents were determined by gas chromatography-mass spectrometry, while contents of CFAs and MDA were determined by high-performance liquid chromatography (HPLC) with photodiode detection. The supplementation of mothers with CLAs significantly decreased the amount of atherogenic saturated FAs and enhanced the level of eicosapentaenoic FA in the hearts of offspring. Continuous progeny supplementation decreased the content of arachidonic acid in hearts. Supplementation of the maternal diet with CLAs and its continuation during the postnatal period increased the ratio of hypo to hypercholesterolemic FAs. Significantly fewer oxysterols were detected in the hearts of progeny of dams fed with CLAs as compared to the offspring of mothers receiving safflower oil. Both fetal and postnatal CLA intake significantly reduced 7β-hydroxycholesterol accumulation. It can be concluded that CLA supplementation during the fetal and postnatal period may be an effective method of maintaining the cardiac health status of newborns.
DDcGAN: A Dual-Discriminator Conditional Generative Adversarial Network for Multi-Resolution Image Fusion

In this paper, we proposed a new end-to-end model, termed as dual-discriminator conditional generative adversarial network (DDcGAN), for fusing infrared and visible images of different resolutions. Our method establishes an adversarial game between a generator and two discriminators. The generator aims to generate a real-like fused image based on a specifically designed content loss to fool the two discriminators, while the two discriminators aim to distinguish the structure differences between the fused image and two source images, respectively, in addition to the content loss. Consequently, the fused image is forced to simultaneously keep the thermal radiation in the infrared image and the texture details in the visible image. Moreover, to fuse source images of different resolutions, e.g., a low-resolution infrared image and a high-resolution visible image, our DDcGAN constrains the downsampled fused image to have similar property with the infrared image. This can avoid causing thermal radiation information blurring or visible texture detail loss, which typically happens in traditional methods. In addition, we also apply our DDcGAN to fusing multi-modality medical images of different resolutions, e.g., a low-resolution positron emission tomography image and a high-resolution magnetic resonance image. The qualitative and quantitative experiments on publicly available datasets demonstrate the superiority of our DDcGAN over the state-of-the-art, in terms of both visual effect and quantitative metrics.

Caregiver Characteristics Associated With Quality of Cardiac Compressions on an Adult Mannequin With Real-Time Visual Feedback

Supplemental digital content is available in the text. Introduction Chest compression (CC) quality directly impacts cardiac arrest outcomes. Provider body type can influence the quality of cardiopulmonary resuscitation (CPR); however, the magnitude of this impact while using visual feedback is not well described. The aim of the study was to determine the association between provider anthropometric variables on fatigue and CC adherence to 2015 American Heart Association CPR while receiving visual feedback. Methods This was a planned secondary analysis of healthcare professionals from multiple hospitals performing continuous CC for 2 minutes on an adult CPR mannequin with dynamic visual feedback. Main outcome measures include compression data (depth, rate, and lean) evaluated in 30-second epochs to explore performance fatigue. Multivariable models examined the relationship of provider anthropometrics to CC quality. Binomial mixed effects models were used to characterize fatigue by examining performance for 4 epochs. Results Three hundred seventy-seven 2-minute CC episodes were analyzed. Extreme (low and high) BMI and weight are associated with poorer CC. Larger size (height, weight, and BMI) is associated with better depth but worse lean compliance. Performance fatigued for all providers for 2 minutes, but shorter, lighter weight, female participants had the greatest decline. On multivariable analysis, rate compliance did not deteriorate regardless of provider anthropometrics. Conclusions Anthropometrics impact provider CC quality. Despite visual feedback, variable effects are seen on compression depth, rate, recoil, and fatigue depending on the provider sex, weight, and BMI. The 2-minute interval for changing chest compressors should be reconsidered based on individual provider characteristics and risk of fatigue's impact on high-quality CPR.
Evaluation of efficacy and tolerability of first-line therapies in NMOSD

Objective To compare the efficacy and the risk of severe infectious events of immunosuppressive agents used early as first-line therapy in patients with neuromyelitis optica spectrum disorder (NMOSD). Methods We retrospectively included patients with NMOSD and a seropositive status for aquaporin 4 or myelin oligodendrocyte glycoprotein antibodies beginning first-line immunosuppressants within 3 years after the disease onset. The main outcome was occurrence of relapse after the initiation of immunosuppressants; the secondary outcome was the annual relapse rate (AAR). Results A total of 136 patients were included: 62 (45.6%) were treated with rituximab (RTX), 42 (30.9%) with mycophenolate mofetil (MMF), and 23 (16.9%) with azathioprine (AZA). Compared with RTX-treated patients, the risk of relapse was higher among MMF-treated patients (hazard ratio [HR], 2.74 [1.17–6.40]; p = 0.020) after adjusting for age at disease onset, sex, antibody status, disease duration, ARR before treatment, corticosteroid intake, and relapse location. We did not observe any difference between RTX-treated and AZA-treated patients (HR, 2.13 [0.72–6.28]; p = 0.17). No interaction was found between the antibody status and immunosuppressive treatments. ARR was lower with RTX than with MMF (p = 0.039), but no difference was observed with AZA. We observed 9 serious infectious events with MMF, 6 with RTX, and none with AZA. Conclusions The use of first-line RTX in NMOSD appears more effective than MMF in suppressing clinical activity, independent of the antibody status. Classification of evidence That study provides Class III evidence that for patients with NMOSD, first-line RTX is superior to MMF to reduce the risk of relapse.
GDF15 promotes simultaneous astrocyte remodeling and tight junction strengthening at the blood–brain barrier

Perivascular astrocyte processes (PAP) surround cerebral endothelial cells (ECs) and modulate the strengthening of tight junctions to influence blood–brain barrier (BBB) permeability. Morphologically altered astrocytes may affect barrier properties and trigger the onset of brain pathologies. However, astrocyte‐dependent mediators of these events remain poorly studied. Here, we show a pharmacologically driven elevated expression and release of growth/differentiation factor 15 (GDF15) in rat primary astrocytes and cerebral PAP. GDF15 has been shown to possess trophic properties for motor neurons, prompting us to hypothesize similar effects on astrocytes. Indeed, its increased expression and release occurred simultaneously to morphological changes of astrocytes in vitro and PAP, suggesting modulatory effects of GDF15 on these cells, but also neighboring EC. Administration of recombinant GDF15 was sufficient to promote astrocyte remodeling and enhance barrier properties between ECs in vitro, whereas its pharmacogenetic abrogation prevented these effects. We validated our findings in male high anxiety‐related behavior rats, an animal model of depressive‐like behavior, with shrunk PAP associated with reduced expression of the junctional protein claudin‐5, which were both restored by a pharmacologically induced increase in GDF15 expression. Thus, we identified GDF15 as an astrocyte‐derived trigger of astrocyte process remodeling linked to enhanced tight junction strengthening at the BBB.
Membrane Chaperoning of a Thylakoid Protease Whose Structural Stability Is Modified by the Protonmotive Force

The lipid environment of the thylakoid membrane chaperones the folding of an integral signal peptidase whose stability is affected by protonmotive force-mimicking pH conditions. Protein folding is a complex cellular process often assisted by chaperones, but it can also be facilitated by interactions with lipids. Disulfide bond formation is a common mechanism to stabilize a protein. This can help maintain functionality amid changes in the biochemical milieu, including those relating to energy-transducing membranes. Plastidic Type I Signal Peptidase 1 (Plsp1) is an integral thylakoid membrane signal peptidase that requires an intramolecular disulfide bond for in vitro activity. We have investigated the interplay between disulfide bond formation, lipids, and pH in the folding and activity of Plsp1. By combining biochemical approaches with a genetic complementation assay using Arabidopsis thaliana plants, we provide evidence that interactions with lipids in the thylakoid membrane have reconstitutive chaperoning activity toward Plsp1. Further, the disulfide bridge appears to prevent an inhibitory conformational change resulting from proton motive force-mimicking pH conditions. Broader implications related to the folding of proteins in energy-transducing membranes are discussed.
En-Bloc Resection of Metastases of the Proximal Femur and Reconstruction by Modular Arthroplasty is Not Only Justified in Patients with a Curative Treatment Option—An Observational Study of a Consecutive Series of 45 Patients

Background: There is little conformity regarding the surgical treatment of metastasis of the proximal femur, especially in palliative patients with limited life expectancy. Patients and Methods: En-bloc resection of secondary bone malignancies of the proximal femur and reconstruction by modular arthroplasty was performed in a consecutive series of 45 patients. The mean follow-up period was 16.4 months (0.6–74.7). Results: The survival rate of all patients was 6.6% (95% CI: 0–14.9) at 74.7 months. There was no significant difference in patients with a solitary or disseminated disease at index operation (log-rank p = 0.1214). Recurrent dislocation was the most frequent local complication (n = 6) necessitating an open reduction in four cases. The use of a Trevira tube showed a higher risk of dislocation compared to the simple bonding of remaining soft tissue (6 out of 28 vs. 0 out of 17; Fisher test: p = 0.0463). The worst-case survival rate with the removal of the arthroplasty for any cause and/or loss to follow-up was 80.0% (95% CI: 44.9–100) at 74.7 months (n = 1 due to low-grade infection). Conclusions: En-bloc resection of metastases and reconstruction by modular arthroplasty is reliable even in patients with very limited life expectancy. Local complications due to tumor growth or instability after intralesional surgery could be managed successfully but recurrent dislocation as the most frequent complication has to be taken into account. The simple bonding of remaining soft tissue around the prosthesis without the use of an attachment tube may reduce the dislocation rate and reoperation risk.
Haematological Parameters in Systemic Lupus Erythematosus Patients at Kenyatta National Hospital, Nairobi

Background: Haematological abnormalities are the most common manifestations of Systemic Lupus Erythematosus (SLE). Anaemia of Chronic Disease (ACD) has been associated with significantly higher disease activity. Thrombocytopenia early in the course of disease is indicative of more severe active disease and if severe it is an independent predictor of damage accrual and mortality. Leucopenia usually reflects disease activity. Objectives: To determine the prevalence of haematological abnormalities, among SLE patients on follow up at Rheumatology and Renal Outpatient clinics at Kenyatta National Hospital. Specifically, the study aimed to describe the prevalence of anaemia, leucopenia, and thrombocytopenia and identify patient factors associated with these abnormalities. Design: Cross-sectional hospital based descriptive study. Setting: Rheumatology out-patient clinic and Renal out-patient clinic at KNH. Subjects: Sixty five patients who fulfilled the 1997 American College of Rheumatology Classification Criteria for SLE. Results: Sixty five eligible SLE patients were recruited into the study. The mean (SD) age was 36.5 (± 12) years. There were 3 (5%) males and 62 (95%) females. Forty nine (75%) patients had at least one abnormality. The abnormalities involved all the three cell lines. The prevalence of abnormalities were; anaemia 43%, leucopenia 26% and thrombocytopenia 20%. Conclusion: Haematological abnormalities were the second most common manifestation of the disease after arthritis and arthralgia among SLE patients on follow up at Kenyatta National Hospital Rheumatology and Renal clinic. Though majority of these abnormalities were mild to moderate and clinically asymptomatic, the proportions of anaemia, leucopenia and thrombocytopenia were substantially high.

Factors Related to Medication Administration Incidents in England and Wales Between 2007 and 2016: A Retrospective Trend Analysis

Supplemental digital content is available in the text. Objectives The aims of the study were to describe medication administration incidents reported in England and Wales between 2007 and 2016, to identify which factors (reporting year, type of incident, patients’ age) are most strongly related to reported severity of medication administration incidents, and to assess the extent to which relevant information was underreported or indeterminate. Methods Medication administration incidents reported to the National Reporting & Learning System between January 1, 2007, and December 31, 2016 were obtained. Characteristics of the data were described using frequencies, and relationships between variables were explored using cross-tabulation. Results A total of 517,384 incident reports were analyzed. Of these, 97.1% (n = 502,379) occurred in acute/general hospitals, mostly on wards (69.1%, n = 357,463), with medicine the most common specialty area (44.5%, n = 230,205). Medication errors were most commonly omitted doses (25.8%, n = 133,397). The majority did not cause patient harm (83.5%, n = 432,097). When only incidents causing severe harm or death (n = 1,116) were analyzed, the most common type of error was omitted doses (24.1%). Most incidents causing severe harm or death occurred in patients aged 56 years or older. For the 10-year period, the percentage of incidents with “no harm” increased (74.1% in 2007 to 86.3% in 2016). For some variables, data were often missing or indeterminate, which has implications for data analysis. Conclusions Medication administration incidents that do not cause harm are increasingly reported, whereas incidents reported as severe harm and death have declined. Data quality needs to be improved. Underreporting and indeterminate data, inaccuracies in reporting, and coding jeopardize the overall usefulness of these data.
FXR activation promotes intestinal cholesterol excretion and attenuates hyperlipidemia in SR‐B1‐deficient mice fed a high‐fat and high‐cholesterol diet

Obeticholic acid (OCA) activates the farnesoid X receptor (FXR) to lower circulating total cholesterol (TC) and high density lipoprotein‐cholesterol (HDL‐C) concentrations and to stimulate fecal cholesterol excretion in mice by increasing hepatic SR‐B1 expression. Here we show that hepatic SR‐B1 depletion by an adenovirus expressing Sr‐b1 shRNA (Ad‐shSR‐B1) attenuated these beneficial effects of OCA in mice on a chow diet. The mRNA levels of ABC cholesterol transporter genes (Abca1, Abcg1, Abcg5, and Abcg8) were unchanged in the liver of hepatic SR‐B1‐depleted mice regardless of OCA treatment; however, a modest increase in Abca1, Abcg5, and Abcg8 mRNA levels was observed in the ileum of vehicle‐treated control mice and Abca1 and Abcg8 mRNA levels were increased more by OCA administration. OCA treatment of Sr‐b1 knock out (KO) mice (Sr‐b1‐/‐) fed a normal chow diet (NCD) displayed a similar lack of transhepatic cholesterol movement, as well as a modest increase in the levels of ileum cholesterol transporter expression. However, OCA treatment of Sr‐b1 KO mice fed a cholesterol‐enriched diet reduced circulating cholesterol and increased fecal cholesterol output to comparable degrees to that of wild‐type (WT) mice, and these effects were accompanied by substantial elevations of mRNA levels of Abca1, Abcg1, Abcg5, and Abcg8 in the ileum of Sr‐b1 KO mice. Our studies suggest that FXR activation stimulates intestinal cholesterol excretion and reduces diet‐induced hyperlipidemia through increased expression of ileal cholesterol transporters when hepatic SR‐B1‐mediated cholesterol movement is absent.
Mothers’ Healthcare Autonomy, Maternal-Health Utilization and Healthcare for Children under-3 Years: Analysis of the Nigeria DHS Data (2008–2018)

This study was designed to simultaneously examine if mothers’ personal healthcare autonomy within the household, and the level of their maternal-healthcare utilization, translates into better preventive (complete immunization) and curative (treatments for diarrhoea, fever and acute respiratory infection) efforts on morbidities in child healthcare. We analysed data pooled from three consecutive waves of the Nigeria Demographic and Health Survey: the surveys of 2008, 2013 and 2018. Using a multilevel logistic regression, we estimated the odds ratio for each of the outcome variables while adjusting for covariates. Findings revealed that mothers’ health autonomy is positively associated with child immunization and treatment of morbidities (except diarrhoea), a relationship moderated by the frequency of mothers’ exposure to media. Additionally, mothers’ healthcare utilization is positively associated with complete immunization, and all forms of morbidity treatment (except diarrhoea). Although the relationship between mothers’ healthcare-utilization and child immunization is not dependent on family wealth, however, the relationship between mothers’ healthcare utilization and treatment of morbidity is dependent. Policy effort should be geared towards stimulating mothers to seek appropriate and timely child healthcare and future studies could consider looking into the mediating role of paternal support in this relationship.
Marital Status, Close Relationships, and All-Cause Mortality: Results From a 10-Year Study of Nationally Representative Older Adults

ABSTRACT Objective Becoming widowed is associated with an increased risk of early mortality. Drawing on theoretical literature related to social support and health, the present study evaluated whether the quantity of close relationships might differentially moderate the relationship between marital status (widowed versus married) and mortality risk 10 years later. Method Data were obtained from the National Social Life Health and Aging Project. A diverse group of older adults (n = 2347) were interviewed three times for 10 years. Information on close friends/family, marital status, and mortality was gathered. Logistic regression and moderation analyses were used to test whether the quantity of close relationships conditioned the risk of death for married and widowed adults 10 years later. Results The quantity of close relationships moderated the association between marital status and mortality risk (B = −0.35, SE = 0.11, p = .002). Compared with their married counterparts, widowed older adults who had fewer than four to six close relationships had an increased risk of death 10 years later (B = −0.35, SE = 0.09, p < .001); similarly, among people who reported few close relationships, widowed adults had an increased risk of death compared with their married counterparts (B = 0.54, SE = 0.15, p < .001). These findings remained significant after accounting for demographics, health behaviors/chronic health conditions, and psychological distress. This effect is comparable to the increased mortality risk associated with smoking cigarettes. Conclusions Having fewer than four to six close relationships is associated with an increased mortality risk for widowed older adults.
Liver injury during highly pathogenic human coronavirus infections

The severe acute respiratory syndrome coronavirus 2 (SARS‐Cov‐2), the pathogen of 2019 novel coronavirus disease (COVID‐19), has posed a serious threat to global public health. The WHO has declared the outbreak of SARS‐CoV‐2 infection an international public health emergency. Lung lesions have been considered as the major damage caused by SARS‐CoV‐2 infection. However, liver injury has also been reported to occur during the course of the disease in severe cases. Similarly, previous studies have shown that liver damage was common in the patients infected by the other two highly pathogenic coronavirus – severe acute respiratory syndrome coronavirus (SARS‐CoV) and the Middle East respiratory syndrome coronavirus (MERS‐CoV), and associated with the severity of diseases. In this review, the characteristics and mechanism of liver injury caused by SARS‐CoV, MERS‐CoV as well as SARS‐CoV‐2 infection were summarized, which may provide help for further studies on the liver injury of COVID‐19.
