Published: January 2020

Background There are neuro-ophthalmologic findings in patients with communicant hydrocephalus (CH). Purpose To investigate the relationships of the optic canal and carotid canal classifications at sphenoid sinus and anterior clinoid process (ACP) pneumatization in patients with CH. Material and Methods In this multicentric retrospective cross-sectional study, the cranial computed tomography (CT) images of 38 patients with CH (20 men, 18 women) and 40 controls (25 men, 15 women) were included. Optic and carotid canal classification at sphenoid sinus, ACP pneumatization, and sphenoid sinus septation were evaluated. Results In the CH group, type 3 optic canal was detected in 21.1% of the patients and type 4 optic canal was detected in 2.6% of the patients on the left side which was significantly different from the control group ( P<0.05). In the CH group, type 3 carotid canal was detected in 21.1% of the patients (left) and 18.4% of the patients (right). ACP pneumatization was present in 13.2% of the patients in the CH group bilaterally. There were positive correlations between optic canal classifications and ACP pneumatization ( P<0.05). There were also positive correlations between the right and left carotid canal classifications and ACP pneumatization ( P<0.05). Conclusion To avoid complications, CT should be evaluated carefully in patients with CH before surgical interventions in sphenoid sinuses and surgeons should work carefully in the sphenoid sinus or adjacent structures. The protrusion possibility of the optic canal or carotid canal to the sphenoid sinus may be higher in pneumatized ACP patients.

Purpose: Rapid diagnosis of genetic mutations is important for targeted therapies such as EGFR tyrosine kinase inhibitors. KRAS mutation and ALK rearrangement are also important in determining treatment. The purpose of our study was to evaluate the diagnostic value of 18F-FDG PET to predict KRAS mutation and ALK rearrangement in order to determine the frequency of these genetic markers in our lung adenocarcinoma cases and contribute to forthcoming meta-analysis studies. Methods: A total of 218 patients with lung adenocarcinoma (EGFR analyzed) who were seen at our clinic between 2012 and 2014 were included in the study. The results of the 18 F-FDG-PET scans for each patient were retrospectively recorded with the associated medical documents. ALK rearrangements were analyzed in 166 of the 218 patients, while 50 of the 218 patients were analyzed for KRAS mutational status. SPSS 15.0 for Windows was used for statistical analysis. Results: FDG avidity was higher in cases with KRAS mutations and ALK rearrangements than those without, but the difference was not significant. ALK rearrangements were more common in younger, female, and nonsmoking patients with lung adenocarcinoma. Conclusions: The small numbers of KRAS mutations and ALK rearrangements are the limitation of this study for evaluation of diagnostic imaging. The frequency of these genetic alterations was as reported in the literature. We believe that our work will contribute to future meta-analysis.
Promising Results From a Video-Feedback Interaction Guidance Intervention for Improving Maternal–Infant Interaction Quality of Depressed Mothers: A Feasibility Pilot Study
Authors: Tryphonopoulos Panagiota D. , Letourneau Nicole 
Published: January 2020

Background Mothers and infants affected by postpartum depression are known to have (1) reduced quality interactions and (2) elevated cortisol levels, both of which are linked to negative developmental outcomes in children. Parent training promoting sensitive and responsive maternal–infant interactions may help optimize development in children of mothers with postpartum depression. Objectives This pilot study tested a video-feedback interaction guidance intervention designed to improve maternal–infant interaction, depressive symptoms, and cortisol patterns of depressed mothers and their infants. Method An experimental, pre-test, post-test design was employed to randomly assign mothers with postpartum depression to intervention ( n = 6) and control ( n = 6) conditions. Intervention mothers received three video-feedback sessions during home visits, provided at three-week intervals. Control participants received three home visits on the same schedule. Results Significant differences favoring the intervention group were observed in maternal–infant interaction quality, especially maternal sensitivity and cognitive growth fostering activities, and in reduced infant diurnal cortisol. Conclusion Professionally guided video-feedback intervention appears to support improvements in interactions between depressed mothers and their infants and optimizes infants’ diurnal cortisol patterns. The findings from this feasibility pilot study have been used to support a large-scale follow-up exploration.

Published: January 2020

Background: Although highly positive results for wear reduction of highly cross-linked polyethylene (HXLPE) have been reported around the 10-year follow-up, the long-term result related to reoperation and wear-related survival is still an issue. Therefore, this study aimed to compare the follow-up results of a single manufacture’s polyethylene liner for >15 years in terms of survival and wear rate. Methods: This retrospective cohort study included 134 primary total hip arthroplasties (THAs) who were followed up for at least 15 years. The mean age at the time of surgery was 50.7 years (conventional polyethylene [CPE] group = 22; HXLPE group = 112). Linear and volumetric wear rates of polyethylene were measured, and the reoperation rate and radiographic osteolysis were evaluated and Kaplan-Meier survival analysis was performed in both groups. Implant-related complications were also examined. Results: HXLPE group showed a significantly lower wear rate in both linear and volumetric wear. None of the hip radiographs showed evidence of loosening or osteolysis in the HXLPE group. The survival rates at 15- to 18-year follow-up were 90.9% and 95.5% in the CPE and HXLPE groups when all-cause reoperation was the endpoint, and 90.9% and 100.0% when the wear-related reoperation was the endpoint, respectively. Implant-related complications were not different between the 2 groups. Conclusions: Wear reduction and osteolysis showed a great advantage in HXLPE after a 15-year follow-up. Although the CPE and HXLPE showed excellent survival, wear and osteolysis were more frequent in the CPE; therefore, the high risk of reoperation in the future should be considered.
Visto, Pero No Escuchado: A Qualitative Arm of a Mixed-Methods Study of Puerto Rican Children With Asthma
Authors: Dowell Jo A. , Ruiz Zulayka 
Published: January 2020

Introduction: Communication among health care providers, caregivers, and children with asthma is challenging and sometimes may exclude the child. This may result in delay in recognizing and responding appropriately to asthma symptoms. The purpose was to conduct focus groups among Puerto Rican children with asthma on communication with their health care provider about their asthma symptoms. Method: The qualitative arm (focus groups) of a mixed-method explanatory sequential study that was used to view communication with their health care provider through the lens of a group of Puerto Rican children. The sample included Puerto Rican children ages 8 to 12 years with asthma ( N = 23). The goal was to develop a child illness representation questionnaire. Results: The perspective of children with asthma provided enriched information to influence the development of instrument subscale on communication. The children were often not heard during a clinical visit. Most of the children express fear of their health care provider. Conclusions: Although this was a small sample, there were indications that children would like to opportunity to tell the story about their experience with having asthma. Further research will lead to the next step toward developing and computing a reliable measure that includes the child in a discussion during a clinical visit.
Cannabis use in pregnancy and breastfeeding: The pharmacist’s role
Authors: Davis Erin , Lee Tiffany , Weber John T. , Bugden Shawn 
Published: January 2020

Background: The recent legalization of cannabis use in Canada requires pharmacists to be able to support their patients with accurate knowledge of its known risks and benefits. Certain populations, such as pregnant and breastfeeding women and their developing children, may be at higher risk than other populations. Methods: The authors independently searched the literature for clinical reports or reviews of the literature regarding the safety of cannabis use in pregnancy and breastfeeding using search terms such as cannabis, marijuana, pregnancy and breastfeeding. Results: This review combines the relevant pharmacological, pharmacokinetic and clinical evidence for the effects of cannabis in this special patient population. The literature demonstrates that some of the constituents of cannabis can reach children in utero and through breastmilk. Given that Δ⁹-tetrahydrocannabinol can be present in breastmilk as quickly as 1 hour after consumption and last up to 6 days, it may not be possible to use cannabis and avoid infant exposure. There is evidence that this exposure may result in cognitive, social and motor defects. Some of these effects may be long term, lasting years. The pharmacist must be able to educate and screen patients regarding marijuana use in pregnancy and breastfeeding, with the ultimate aim of harm reduction.

Published: January 2020

The study analyzes biochemical and cell kinetic parameters to characterize solid tumor growth in humans. The concentrations of polyamines, CEA, the thymidine labeling index (T.L.I.) and the mitotic index (M.I.) were determined on fragments of neoplastic tissue from 18 patients with breast carcinoma. Urinary polyamines were evaluated in the same patients. Two groups of patients were distinguished according to the median value of the T.L.I. In the group with high T.L.I., M.I. and tissue polyamines were significantly higher than in the group with low T.L.I., whereas tissue CEA was lower, though in a not statistically significant way. Urinary polyamines showed no variations between groups. These preliminary results showed that T.L.I. levels were higher in patients who relapsed during a 4-year follow-up than in patients achieving complete remission and remaining disease free. Results concerning polyamine concentration showed that the tissue polyamine level in breast carcinoma indicated proliferative activity, but this does not seem to be valuable for current prognostic purposes
A Kinetic Model for Glucose Levels and Hemoglobin A1c Provides a Novel Tool for Individualized Diabetes Management
Authors: Xu Yongjin , Dunn Timothy C. , Ajjan Ramzi A. 
Published: January 2020

Background: Regular assessment of glycated hemoglobin (HbA1c) is central to the management of patients with diabetes. Estimated HbA1c (eHbA1c) from continuous glucose monitoring (CGM) has been proposed as a measure that reflects laboratory HbA1c. However, discrepancies between the two markers are common, limiting the clinical use of eHbA1c. Therefore, developing a glycemic maker that better reflects laboratory HbA1c will be highly relevant in diabetes management. Methods: Using CGM data from two previous clinical studies in 120 individuals with diabetes, we derived a novel kinetic model that takes into account red blood cell (RBC) turnover, cross-membrane glucose transport, and hemoglobin glycation processes to individualize the relationship between glucose levels and HbA1c. Results: Using CGM data and two laboratory HbA1c measurements, kinetic rate constants for RBC glycation and turnover were calculated. These rate constants were used to project future HbA1c, creating a new individualized glycemic marker, termed calculated HbA1c (cHbA1c). In contrast to eHbA1c, the new glycemic marker cHbA1c gave an accurate estimation of laboratory HbA1c across individuals. The model and data demonstrated a non-linear relationship between laboratory HbA1c and steady-state glucose and also showed that glycation status is modulated by age. Conclusion: Our kinetic model offers mechanistic insights into the relationship between glucose levels and glycated hemoglobin. Therefore, the new glycemic marker does not only accurately reflect laboratory HbA1c but also provides novel concepts to explain the mechanisms for the mismatch between HbA1c and average glucose in some individuals, which has implications for future clinical management.
Let’s talk about sex: A review of expectations, body image and sexual function in exstrophy
Authors: Tregunna Rebecca L , Wood Dan 
Published: January 2020

Background: The bladder exstrophy epispadias complex (BEEC) is a rare disorder characterised by a number of genito-urinary abnormalities. The condition and subsequent treatment may result in lasting effects on continence, renal function and fertility. There are equally important psychosocial and psychosexual effects as part of overall long-term quality of life. The literature consists largely of small studies with variable methodology; this study aims to consolidate these data. Methods: This study reviews the available literature sourced from the Medline database using the keywords listed below. Results: Patients appear to be high achievers with good overall health-related quality of life. Most form close personal friendships although express anxiety related to revelation of their condition. Data suggest the majority of patients are able to engage in and be satisfied with sexual intercourse. Fertility may be adversely affected, but this can usually be overcome with assisted reproductive techniques and specialist input during pregnancy and delivery. Conclusions: Psychosocial and psychosexual outcomes in patients with BEEC may be excellent. Therefore careful transition and psychological support combined with long-term follow-up is important to allow these patients to maximise their quality of life. Level of evidence: Not applicable.
Significant Burden and Psychological Distress Among Caregivers of Children With Nephrotic Syndrome: A Cross-Sectional Study
Authors: Esezobor Christopher I. , Solarin Adaobi U. , Olagunju Andrew T. 
Published: January 2020

Background: Childhood nephrotic syndrome (NS) follows a chronic course in most children. However, little is known about the psychosocial burden of NS on the caregivers despite evidence that caregiver burden or impairment in their well-being may alter the outcome of chronic childhood illnesses. Objectives: To determine the frequency and predictors of significant caregiver burden and psychological distress among caregivers of children with NS. Design: A cross-sectional study. Setting: Two pediatric nephrology clinics in Lagos, Nigeria. Patients: We included primary caregivers of children with idiopathic NS for at least 6 months. Measurements: The primary outcomes were psychological distress and significant caregiver burden among caregivers. Methods: We interviewed caregivers using the 12-item General Health Questionnaire (GHQ-12) and the 6-item Zarit Burden Interview (ZBI-6). The GHQ-12 scores ≥ 3 and ZBI-6 scores ≥ 6 indicated psychological distress and significant caregiver burden, respectively. Results: The caregivers were mostly mothers (77.9%) and married (92.4%), whereas the children (n = 172) were mainly male (65.1%). Most of the children (n = 152; 88.4%) had steroid-sensitive NS including 24 (14%) children with frequent relapses or steroid dependence and 20 (11.6%) with steroid-resistant NS. Of the 172 caregivers, 53 (30.8%) and 30 (17.4%) reported psychological distress and significant burden, respectively. Caregivers of children in relapse had adjusted an odds ratio (aOR) with 95% confidence interval (CI) of 2.45 (1.05-5.67) and 3.30 (1.22-8.92) of psychological distress and significant caregiver burden, respectively. Furthermore, caregivers of male children and those who needed help paying for health care had an aOR of 4.61 (1.34-15.68) and 3.06 (1.06-8.87) of significant caregiver burden, respectively. Limitations: The study was limited by its cross-sectional design and the use of generic rather than disease-specific instruments. Conclusion: One in every 6 caregivers of children with idiopathic NS reported significant caregiver burden, and it was associated with psychological distress. Our findings underscore the need for psychosocial support for caregivers of children with NS, especially those with identifiable vulnerability.

Published: January 2020

Objective To date the application of eHealth strategies among adults and adolescents undergoing metabolic and bariatric surgery (MBS) has not been systematically reviewed. This study comprehensively examines eHealth intervention studies among MBS patients within the RE-AIM framework to assess reach, effectiveness, adoption, implementation and maintenance of these efforts. Methods A search was conducted using PubMed, EMBASE, CINAHL, PsycNET and SCOPUS of original research relating to eHealth strategies for MBS patients published in peer-reviewed journals and revealed 38 published articles between 2011 and 2019. Results Studies varied widely in terms of design (qualitative to randomized controlled trials) and eHealth delivery method (telemedicine to blog post content) with a balance of pre- or post-MBS use. No studies included adolescents and very few reported (1) a conceptual framework to support study design/outcomes; and (2) race/ethnicity composition. Conclusions Although some studies report that eHealth strategies/interventions are effective in producing post-MBS weight loss and other positive health outcomes, most are pilot studies or have study design limitations. There is an opportunity for development of (1) tailored eHealth interventions to support pre- and post-MBS sustained behavior change and improved outcomes; and (2) rigorous studies that employ robust conceptual frameworks so dissemination and implementation efforts can be mapped to construct-driven outcomes.

Abstract
Background
The genus Trichococcus currently contains nine species: T. flocculiformis, T. pasteurii, T. palustris, T. collinsii, T. patagoniensis, T. ilyis, T. paludicola, T. alkaliphilus, and T. shcherbakoviae. In general, Trichococcus species can degrade a wide range of carbohydrates. However, only T. pasteurii and a non-characterized strain of Trichococcus, strain ES5, have the capacity of converting glycerol to mainly 1,3-propanediol. Comparative genomic analysis of Trichococcus species provides the opportunity to further explore the physiological potential and uncover novel properties of this genus.

Results
In this study, a genotype-phenotype comparative analysis of Trichococcus strains was performed. The genome of Trichococcus strain ES5 was sequenced and included in the comparison with the other nine type strains. Genes encoding functions related to e.g. the utilization of different carbon sources (glycerol, arabinan and alginate), antibiotic resistance, tolerance to low temperature and osmoregulation could be identified in all the sequences analysed. T. pasteurii and Trichococcus strain ES5 contain a operon with genes encoding necessary enzymes for 1,3-PDO production from glycerol. All the analysed genomes comprise genes encoding for cold shock domains, but only five of the Trichococcus species can grow at 0 °C. Protein domains associated to osmoregulation mechanisms are encoded in the genomes of all Trichococcus species, except in T. palustris, which had a lower resistance to salinity than the other nine studied Trichococcus strains.

Conclusions
Genome analysis and comparison of ten Trichococcus strains allowed the identification of physiological traits related to substrate utilization and environmental stress resistance (e.g. to cold and salinity). Some substrates were used by single species, e.g. alginate by T. collinsii and arabinan by T. alkaliphilus. Strain ES5 may represent a subspecies of Trichococcus flocculiformis and contrary to the type strain (DSM 2094T), is able to grow on glycerol with the production of 1,3-propanediol.
Natural and pathogenic protein sequence variation affecting prion-like domains within and across human proteomes
Authors: Cascarina Sean M. , Ross Eric D. 
Published: January 2020

Abstract
Background
Impaired proteostatic regulation of proteins with prion-like domains (PrLDs) is associated with a variety of human diseases including neurodegenerative disorders, myopathies, and certain forms of cancer. For many of these disorders, current models suggest a prion-like molecular mechanism of disease, whereby proteins aggregate and spread to neighboring cells in an infectious manner. The development of prion prediction algorithms has facilitated the large-scale identification of PrLDs among “reference” proteomes for various organisms. However, the degree to which intraspecies protein sequence diversity influences predicted prion propensity has not been systematically examined.

Results
Here, we explore protein sequence variation introduced at genetic, post-transcriptional, and post-translational levels, and its influence on predicted aggregation propensity for human PrLDs. We find that sequence variation is relatively common among PrLDs and in some cases can result in relatively large differences in predicted prion propensity. Sequence variation introduced at the post-transcriptional level (via alternative splicing) also commonly affects predicted aggregation propensity, often by direct inclusion or exclusion of a PrLD. Finally, analysis of a database of sequence variants associated with human disease reveals a number of mutations within PrLDs that are predicted to increase prion propensity.

Conclusions
Our analyses expand the list of candidate human PrLDs, quantitatively estimate the effects of sequence variation on the aggregation propensity of PrLDs, and suggest the involvement of prion-like mechanisms in additional human diseases.
