Published: December 2019

Introduction: In squamous cell carcinomas of the oral cavity, factors that can predict prognosis are being studied. However, new prognostic factors are needed to provide information on the biological properties of tumors. Galectin-3 is known to be involved in many biological events such as cell adhesion and differentiation, angiogenesis, apoptosis, tumorigenesis, and metastasis. In our study, the prognostic role of galectin-3 expression in squamous cell carcinomas of the oral cavity was investigated. Materials and Methods: The study included 60 patients with a diagnosis of squamous cell carcinoma of the oral cavity. The demographic characteristics of the patients were compiled from the patient files. Galectin-3 expression was studied immunohistochemically. Cytoplasmic and nuclear expressions of galectin-3 were evaluated separately. In addition, the total expression score was calculated by multiplying the percentage and intensity scores for each cases. The critical expression score was determined according to the median value of the total scores. Results: Among 60 cases, 28 tumors were located on the lip, 21 on the tongue, 4 on the floor of the mouth, 3 on the orobuccal mucosa, 3 on the retromolar trigone, and 1 on the gingivobuccal junction. There was no statistically significant relationship between prognosis and nuclear or cytoplasmic galectin-3 expression. Tumor grade and invasion pattern were found to be associated with the galectin-3 total expression score. Conclusion: Although galectin-3 total expression score was correlated with the tumor grade and invasion pattern, it is not associated with overall survival or recurrence rates. However, there is a need for a large series of cases in which methods are standardized in order to clarify the prognostic role of galectin-3 expression in oral squamous cell carcinomas.

Background According to the as low as reasonably achievable (ALARA) principle, radiation exposure in computed tomography (CT) should be minimized while maintaining adequate image quality. Dedicated CT protocols combined with iterative reconstruction (IR) can reduce radiation dose and/or improve image quality. Purpose To investigate the feasibility of extremely reduced-dose (RD) CT of the thoracic spine in human cadavers using a standard-dose (SD) and three different RDCT protocols reconstructed with filtered back projection (FBP) and IR. Material and Methods The thoracic spines of 11 cadavers were examined using different RDCT protocols with decreasing reference tube currents (RDCT-1: 50 mAs; RDCT-2: 30 mAs; RDCT-3: 10 mAs) at 140 kV. A clinical SDCT (70 mAs, 140 kV) served as reference. Raw data were reconstructed using FBP and two increasing levels of IR (IRL4 and IRL6). Images were evaluated for image quality, diagnostic acceptability, and visibility of anatomical structures according to a 5-point-scale. Results Regardless of the reconstruction technique, image quality was rated as diagnostically acceptable for all cadavers in SDCT and RDCT-1. Image quality of reconstructions with FBP were generally rated lower. Application of IR improved image quality ratings in SDCT and RDCT. RDCT-2 with IR was the most reduced-dose CT protocol which enabled diagnostically acceptable image quality in all cadavers. Compared to SDCT, RDCT protocols resulted in significantly reduced effective radiation doses (SDCT: 4.1 ± 1.5 mSv; RDCT-1: 2.9 ± 1.1 mSv; 2:1.7 ± 0.6 mSv; 3:0.6 ± 0.1 mSv; P = 0.001). Conclusion Diagnostically acceptable RDCT of the thoracic spine with 1.7 mSv is feasible using IR.

Objective Obesity has been linked to cardiovascular disease, diabetes, and osteoarthritis. Obesity and overweight pose a serious threat to human health, with an estimated 190 million overweight and obese people worldwide. Thus, we investigated the influence of certain eating habits on weight among Chinese college students. Methods We conducted a cross-sectional survey of 536 college students in Shijiazhuang, China. The survey included questions about eating habits. We analyzed the relationship between participants’ responses and obesity. Results Sex, residence, speed of eating, number of meals eaten per day, and a diet high in sugar were found to be correlated with obesity. Our results suggest that increasing the number of meals per day, slowing down the pace of eating, and reducing the intake of high-sugar foods have potential benefits for reducing obesity among college students. Conclusions In the present study, we found that some dietary habits are related to the occurrence of obesity among college-aged individuals.

Authors: Gyapay Julia , Freeman Shannon , Flood Donna 
Published: December 2019

Background: Informal caregiver support programs offered by hospice organizations support the health and wellbeing of clients and caregivers. However, an understanding of the best practices for informal caregiver support programs currently undertaken across Canada remains unknown, particularly across the province of British Columbia. Aim: The aim of the present study was to describe what existing resources and supports are provided by hospice organizations for informal caregivers of persons who are nearing end of life or who are recently bereaved in British Columbia, Canada. Methods: In this descriptive study, two thirds of hospice organizations (N = 42/66; 26 urban, 16 rural) participated in a semi-structured telephone interview focused on informal caregiver support programs. All interviews were recorded, transcribed and analyzed thematically and descriptive statistics were employed. Findings: While no one-size-fit-all caregiver support program emerged as a gold standard across all hospice organizations, nearly two thirds (n = 26/42) offered one or more informal caregiver support programs. Four categories of caregiver support programs emerged from the data analysis, including companioning, bereavement and grief supports, education and service supports, and respite for caregivers. Conclusion: Caregiver support programs are a valuable service provided by some but not all hospice organizations across British Columbia, Canada. Future studies are needed to determine best methods for hospice organizations to formally assess caregivers’ needs and to determine the success and effectiveness of such programs in support of program expansion and evaluation.

Background and Objective: This study compared sleep disturbances between older adults living in nursing home located in high- and low-altitude areas and explored the association between sleep disturbances and quality of life (QoL). Method: In total, 207 participants living in a high-altitude area and 437 participants in a low-altitude area were included. Sleep disturbances (ie, difficulty in initiating sleep, difficulty in maintaining sleep, and early morning awakening) were measured using standardized questions. The independent demographic and clinical correlates of sleep disturbances in high-altitude area were examined using multiple logistic regression analyses. Each type of sleep disturbance was entered as the dependent variable separately, while those with significant group differences in the univariate analyses (ie, male gender, married status, age and depressive symptoms) were entered as independent variables. Results: The prevalence of any type of sleep disturbances in the whole sample was 26.09%, with 41.54% in the high-altitude area and 18.76% in the low-altitude area. Physical, psychological, social, and environmental QoL domains were negatively associated with sleep disturbances in high-altitude area. Multiple logistic regression analyses revealed that male gender and married status were less likely to have sleep disturbances, while those with more severe depressive symptoms were more likely to have sleep disturbances in high-altitude area. Conclusion: Sleep disturbance is common among older nursing home residents in high-altitude areas. Considering the negative impact of sleep disturbance on QoL, regular screening and treatment strategies need to be developed directly for this population.

Objectives: Deep vein thrombosis (DVT) is a major health-care burden in Europe, but exact estimates are lacking. This study reports results from the PREFER venous thromboembolism (VTE) study concerning health-related quality of life (HrQoL) and mortality of patients with DVT. Methods: PREFER VTE was a prospective, observational study, conducted in 7 European countries, designed to provide data concerning treatment patterns, resource utilization, mortality, and QoL. First-time or recurrent patients with DVT were followed at 1, 3, 6, and 12 months. Health-related QoL—as measured by the EuroQoL 5-Dimension 5-Level instrument ( EQ-5D-5L)—was analyzed using Tobit regression with repeated measures, assessing the impact of baseline characteristics stratified by cancer activity. Mortality was analyzed using logistic regression. Results: At baseline, patients with DVT had a 0.14 lower EQ-5D-5L index score (0.72 for total sample) compared to the reference UK population (0.85). The EQ-5D-5L index score improved from baseline to 12 months in patients with active cancer (from 0.70 to 0.79) and those without (0.72-0.87); 7.3% died within a year, a 5.2% excess mortality compared to the age- and gender-adfjusted general population. The 12-month mortality rate of DVT varied between 2.9% in the pooled data from Germany, Switzerland, or Austria and 15.4% in Italy. Furthermore, the mortality rate differed between patients with active cancer and those without (42.9% vs 4.7%). Conclusions: Deep vein thrombosis is associated with a substantial burden of illness in terms of HrQoL at baseline, which following treatment normalizes after 12 months and has a significant mortality rate. In addition, active cancer has a significant impact on mortality and the HrQoL of patients with DVT.

Published: December 2019

Introduction Elevated serum beta human chorionic gonadotrophin (β-hCG) in a female normally indicates pregnancy or possibly, gestational trophoblastic disease or ovarian germ cell tumours. Expression of β-hCG has been demonstrated in cervical and endometrial carcinoma and other non-germ cell tumours of the ovary, vulva, breast, prostate, lung, colon, oral/facial tissue and stomach. Case report We report a 43-year-old premenopausal woman with p16 positive squamous cell anal cancer. Pre-treatment urinary screening was positive for β-hCG (218 IU/L), which was confirmed on serum and expressed in the tumour. Pelvic ultrasound ruled out pregnancy. Cervical cytology detected human papilloma virus p16 infection and a potential squamous intraepithelial lesion. Management and outcome: She received definitive chemoradiation (Mitomycin/5-fluorouracil) for six weeks. β-hCG, taken four weeks post completion, had returned to normal levels (<2 IU/L). Discussion Cases of elevated serum β-hCG are documented in different cancers including breast, gastric, lung, ovarian and renal cell. In our case, the elevated β-hCG is probably ectopic excretion by the squamous cell carcinoma tumour in the anus. While this has never been reported previously in the anus, it is likely due to the documented risk of development of precancerous as well as cancerous anal and cervical lesions through human papilloma virus infection. Raised levels of β-hCG have been reported in cervical cancers. Other possible causes of β-hCG elevation were excluded. Following treatment, her β-hCG level returned to normal strengthening the hypothesis that β-hCG elevation was due to the anal carcinoma. In conclusion, unexplained ectopic secretion of β-hCG may be the first sign of a primary malignancy.

Objectives The aim of this study was to investigate whether Australian cat owners are effectively meeting their cats’ environmental needs and to identify areas of deficiency that may have an impact on the cats’ health and welfare. Methods An online survey investigating lifestyle factors and provision of environmental resources was distributed to Australian cat owners. Results In total, 12,010 respondents, representing cat-owning households, completed the survey. Altogether, 45.5% were single-cat households and 54.5% were multi-cat households, with a mean number of two cats per household. In total, 46.3% of households contained indoor cats, 51.8% contained indoor–outdoor cats and 1.8% had mostly outdoor cats. Dry food was the predominant food type in 59% of households and few respondents fed their cats in a manner that stimulates natural predatory behaviours. Altogether, 17.1% of households reported cats with urinary problems such as haematuria or urethral obstruction, and 19.8% reported inappropriate urination outside of the litter tray. The incidence of urinary problems was found to be significantly increased in multi-cat households, those with a low number of litter trays, less frequent cleaning of the trays of faeces and the use of crystal type litter. The veterinary clinic was the most common place to obtain advice about feeding and toileting management. Conclusions and relevance An increased number of Australian households now contain multiple cats that live restricted or indoor lifestyles. Despite the majority of respondents claiming to have a lot of knowledge about cats and obtaining veterinary advice, deficiencies were identified in toileting facilities and feeding practices, which raises significant welfare concerns. Urinary tract disorders are an important cause of morbidity, mortality and relinquishment and its presence was associated with inadequate toileting facilities. Ongoing education of cat owners and an increased effort by veterinarians to include basic husbandry in preventative care consultations is critical to improving the welfare of pet cats.
Novel presentation of eosinophilic granuloma complex in a cat
Authors: Hopke Kaitlin P , Sargent Sandra J 
Published: December 2019

Case summary A 9-year-old neutered male domestic shorthair cat was presented for multiple deep lesions on all four limbs and a nodule on the right pinna. The limb lesions ranged from nodules with necrotic surfaces to full-thickness ulcerations with exposure of muscles and tendons. The cat lived indoors only in a single-pet household and had no prior history of trauma. The owner reported that the lesions appeared abruptly and that the cat was not apparently painful or pruritic. Histopathology of the limb lesions and pinnal nodule confirmed severe lesions of the eosinophilic granuloma complex. Resolution of lesions was achieved with a combination of antibiotics, prednisolone, topical therapies, diet change and ciclosporin. Relevance and novel information This case report demonstrates a severe, aggressive presentation of eosinophilic granuloma complex. It will expose practitioners to atypical clinical signs of this commonly diagnosed disease.
Radiologic Contrast Media Desensitization for Delayed Cardiac Catheterization
Authors: Sanan Neha , Rowane Marija , Hostoffer Robert 
Published: December 2019

This protocol for rapid desensitization to intravenous radiographic contrast material (RCM) improves the strategy first reported by Uppal et al. Desensitization is a validated preventative measure for medical emergencies, such as cardiac catheterization, when patients present with histories of anaphylactoid reactions to the allergen of concern. The patient required another catheterization that was modified to repeat the final dosage of 320 mg/mL of Visipaque®, accommodating cardiac catheterization postponement, contrary to readministration of doses 4 (0.625 mg/mL) and 8 (10 mg/mL) as reported in Uppal et al. Our risk score calculations suggested that the patient was at low risk of contrast-induced nephropathy (CIN) that did not necessitate reduced dosage. No complications were reported following catheterization. We propose repetition of the final RCM dosage as a more effective and efficient desensitization strategy, as long as the scoring system does not indicate high risk for CIN.

Background: Reports have concluded that platelet-rich plasma (PRP) is an effective and safe biological approach in the treatment of knee osteoarthritis (OA). However, no consensus has been established regarding the number of injections required to observe a therapeutic effect. Purpose: To compare the clinical effectiveness reported in randomized controlled trials (RCTs) of single versus multiple PRP injections in the treatment of knee OA. Study Design: Systematic review; Level of evidence, 1. Methods: A comprehensive search was conducted for RCTs published between 1970 and 2019 that compared the effect of single versus multiple PRP injections on pain and functionality in patients with knee OA. Searched databases included MEDLINE, Scopus, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials. A data extraction form was designed to obtain bibliographic information of the study as well as patient, intervention, comparison, and outcomes of interest data. A random-effects model was used to pool quantitative data from the primary outcomes. Results: We included 5 clinical trials with a low-moderate risk of bias that reported data for 301 patients. Meta-analysis showed that, at 6 months after the intervention, single and multiple (double or triple) injections had similar pain improvement, with no significant differences (standardized mean difference [SMD], 0.61 [95% CI, −1.09 to 2.31]; I 2 = 97%; P = .48). A significant improvement in knee functionality was observed in favor of multiple injections (SMD, 2.29 [95% CI, 0.45-4.12]; I 2 = 97%; P = .01). Subanalysis showed that the significant improvement was only evident for the results of single versus triple injections (SMD, 3.12 [95% CI, 0.64-5.60]; I 2 = 97%; P = .01). Conclusion: According to our results, a single injection was as effective as multiple PRP injections in pain improvement; however, multiple injections seemed more effective in joint functionality than a single injection at 6 months. We consider that the available evidence is still insufficient, and future research on this specific topic is needed to confirm our results.

Published: December 2019

AbstractPrepared composite materials based on [Zn4O(benzene-1,4-dicarboxylate)3] (MOF-5) and graphene oxide (GO) via a simple green solvothermal method, at which GO was used as platform to load MOF-5, and applied to the thermal decomposition of AP. The obtained composites were characterized by various techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), nitrogen adsorption, Fourier transform infrared (FT-IR), differential scanning calorimetry and thermalgravimetric (DSC-TG). The analyses confirmed that the composite material (GO@) MOF-5 can not only improve the decomposition peak temperature of AP from the initial 409.7 °C to 321.9 °C, but also can improve the enthalpy (△H) from 576 J g−1 to 1011 J g−1 and reduce the activation energy (Ea), thereby accelerating the decomposition reaction. The high-specific surface area of the MOF material can provide a large number of active sites, so that the transition metal ions supported thereon can participate more effectively in the electron transfer process, and GO plays its role as a bridge by its efficient thermal and electrical conductivity. Together, accelerate the thermal decomposition process of AP.
