ABSTRACT

Attention is an important resource for prioritizing information in working memory (WM), and it can be deployed both strategically and automatically. Most research investigating the relationship between WM and attention has focused on strategic efforts to deploy attentional resources toward remembering relevant information. However, such voluntary attentional control represents a mere subset of the attentional processes that select information to be encoded and maintained in WM (Theeuwes, Journal of Cognition, 1[1]: 29, 1-15, 2018). Here, we discuss three ways in which information becomes prioritized automatically in WM-physical salience, statistical learning, and reward learning. This review integrates findings from perception and working memory studies to propose a more sophisticated understanding of the relationship between attention and working memory.

ABSTRACT

OBJECTIVE: To determine the median survival time (MST) of dogs with nasal carcinoma treated with toceranib phosphate.

MATERIAL AND METHODS: The databases of four Spanish referral hospitals were retrospectively searched for dogs with a diagnosis of nasal tumours presented between January 2015 and October 2020. Dogs treated with radiotherapy or other chemotherapies prior toceranib were excluded.

RESULTS: Twenty-three dogs with a confirmed nasal carcinoma treated with toceranib phosphate and with a CT scan for initial staging according to Adams Modified Staging System were included. Nine dogs had a stage III nasal carcinoma whereas 14 dogs had a stage IV nasal carcinoma. No dog had stages I and II nasal carcinoma. The median overall survival time was 139 days. The difference between the MST between dogs with stages III and IV was not statistically significant [P = 0.6, 140 days for stage III (range 46-401) vs 120 days for stage IV (range 23-600)]. Overall, dogs with epistaxis achieved a longer median survival (166 days) than dogs without epistaxis (83 days). Toceranib phosphate was generally well tolerated. Most dogs had an initial clinical benefit followed by progressive disease.

SIGNIFICANCE: This is the first study to report the MST in dogs with stages III and IV nasal carcinoma treated with toceranib phosphate. This retrospective study showed that toceranib phosphate decreases the clinical signs associated with nasal carcinomas.

ABSTRACT

Experimental psychologists often neglect the poor psychometric properties of the dependent measures collected in their studies. In particular, a low reliability of measures can have dramatic consequences for the interpretation of key findings in some of the most popular experimental paradigms, especially when strong inferences are drawn from the absence of statistically significant correlations. In research on unconscious cognition, for instance, it is commonly argued that the lack of a correlation between task performance and measures of awareness or explicit recollection of the target stimuli provides strong support for the conclusion that the cognitive processes underlying performance must be unconscious. Using contextual cuing of visual search as a case study, we show that given the low reliability of the dependent measures collected in these studies, it is usually impossible to draw any firm conclusion about the unconscious character of this effect from correlational analyses. Furthermore, both a psychometric meta-analysis of the available evidence and a cognitive-modeling approach suggest that, in fact, we should expect to see very low correlations between performance and awareness at the empirical level, even if both constructs are perfectly related at the latent level. Convincing evidence for the unconscious character of contextual cuing and other effects will most likely demand richer and larger data sets, coupled with more powerful analytic approaches.

ABSTRACT

Fatty acid binding protein 5 (FABP5) is elevated in psoriatic keratinocytes and could be involved in systemic metabolic disturbances in psoriasis. The aim of the study was to evaluate serum FABP5 in obese and non-obese psoriatic patients, to assess the relationship between FABP5 and the duration, severity of the disease, inflammatory and metabolic markers and influence of treatment with narrowband-ultraviolet B (NB-UVB). Seventy-four patients (30 treated with NB-UVB) with psoriasis were enrolled in the study. The serum concentrations of FABP5 were measured using Human FABP5 Enzyme-Linked Immunosorbent Assay kit. Serum fatty acids were measured by gas-liquid chromatography. Serum FABP5 levels in psoriatic patients were higher versus control group (P < 0.001). FABP5 in patients with PASI > 20 was higher compared to the mild group (PASI < 10) (P < 0.001) and serum FABP5 correlated positively with PASI score (r = 0.41, P < 0.001). There was also positive correlation between FABP5 and basic inflammation indices. Decrease of PASI after NB-UVB treatment (P < 0.001) was observed and accompanied by decrease of the serum FABP5 (P = 0.007). FABP5 is a potential marker of psoriasis, its severity and clinical outcome after therapy with NB-UVB. FABP5 may reflect metabolic disturbances in psoriatic patients.

ABSTRACT

Present study was carried out to explore heavy metals pollution and potential ecological risk factors associated with agriculture soil irrigated with industrial effluents of Hayatabad industrial estate, Peshawar (HIEP) and Gadoon industrial estate, Sawabi (GIES) of Khyber-Pakhtunkhwa, Pakistan through multivariate geo-statistical tools. Diverse statistical tools like cluster analysis (HC) and principal component analysis (PCA), along with geo-statistical approaches were applied to highlight the geogenic and anthropogenic sources of pollution. The results indicated that concentration of heavy metals in target areas was significantly higher than control. Both soils had significant to moderate enrichment of heavy metals, while Gadoon soil had moderate to considerable ecological risk factor. The geo accumulation indices (Igeo) tendency for heavy metals in both target soil (Gadoon and Hayatabad) were the same. The Pb concentration of both target areas falls in the extremely severely polluted category because of the excessive presence of industries producing lead-containing products. Hence, this study indicated that the majority of toxic heavy metals contributed to soil pollution in the studied areas are coming from industrial and commercial activities.

ABSTRACT

To evaluate potential factors associated with the risk of perioperative blood transfusion (PBT) with implications on length of hospital stay (LOHS) and major post-operative complications in patients who underwent robot-assisted radical prostatectomy (RARP) as a primary treatment for prostate cancer (PCa). In a period ranging from January 2013 to August 2019, 980 consecutive patients who underwent RARP were retrospectively evaluated. Clinical factors such as intraoperative blood loss were evaluated. The association of factors with the risk of PBT was investigated by statistical methods. Overall, PBT was necessary in 39 patients (4%) in whom four were intraoperatively. Positive surgical margins, operating time and intraoperative blood loss were associated with perioperative blood transfusion on univariate analysis. On multivariate analysis, the risk of PBT was predicted by intraoperative blood loss (odds ratio, OR 1.002; 95% CI 1.001-1.002; p < 0.0001), which was associated with prolonged operating time and elevated body mass index (BMI). PBT was associated with delayed LOHS and Clavien-Dindo complications > 2. In patients undergoing RARP as a primary treatment for PCa, the risk of PBT represented a rare event that was predicted by severe intraoperative bleeding, which was associated with increased BMI as well as with prolonged operating time. In patients who received a PBT, prolonged LOHS as well as an elevated risk of major Clavien-Dindo complications were seen.

ABSTRACT

PURPOSE: Morphine infusion through Intrathecal Drug Delivery System (IDDS) is widely used to relieve refractory cancer pain. However, continuous escalation of morphine dose caused by opioid tolerance and/or progress of cancer was commonly observed. Combining morphine with medications of different analgesic mechanisms is applied to blunt the rate of morphine increase. The purpose of this study was to determine the analgesic efficacy and safety of combining gabapentin with morphine after IDDS implantation.

METHODS: This study compared patients that received IDDS implantation from January 1, 2017 to November 10, 2018 in our institute. Key outcomes included change in mean pain score, dose of morphine used in patients, percentage of patients with 30% and 50% reduction in mean pain score, Patient Global Impression of Change scores, breakthrough pain characters and side effects.

RESULTS: 34 patients in the combination group (morphine + gabapentin) and 40 patients in the monotherapy group(morphine)were analyzed. The results showed that both therapy groups achieved similar analgesic efficacy, demonstrated by Numerical rating scale (2.42 ± 0.88 vs 2.57 ± 0.85; Combination vs Monotherapy), PGIC and responder status. Mean daily dose of morphine was significantly lower in combination group compared to monotherapy group (3.54 ± 1.29 mg vs 4.64 ± 1.28 mg, P = 0.007). More patients experienced dizziness and somnolence after receiving combination therapy compared to morphine-alone treatment although no statistical significance was found (P = 0.49).

CONCLUSION: Addition of gabapentin achieved similar analgesic efficacy with lower dose of morphine compared to morphine alone accompanying with higher incidence of dizziness and somnolence.

ABSTRACT

PURPOSE: The family of leukemia patients, due to their caring role, often feels psychological distress. A practical need-based program carefully considers the set of requirements of nursing service recipients. This paper illustrates the efficacy of a designed family-need-based program on relieving stress, anxiety, and depression of family caregivers of leukemia patients.

METHODS: In this controlled trial, sixty-four family caregivers of leukemia patients referring to a medical center in Iran were recruited by convenience sampling and randomly divided into study and control groups. The study group attended a designed need-based program. The control group did not receive the intervention. Stress, anxiety, and depression of both groups were simultaneously measured and compared in three time-points using the scale of stress, anxiety, and depression (DASS-42). Data were analyzed using descriptive and inferential statistics.

RESULTS: Before the program, the average scores of stress, anxiety, and depression were 31.16 ± 4.14, 21.37 ± 6.31, and 27.56 ± 4.24 for the study group and 31.09 ± 4.48, 20.34 ± 6.56, and 28.78 ± 4.72 for the control group. After the program, the average scores of stress, anxiety, and depression were 10.56 ± 3.37, 6.75 ± 2.99, and 7.37 ± 2.76 for the study group and 34.87 ± 2.51, 23.65 ± 4.96, and 32.56 ± 3.49 for the control group, respectively. Results of the independent t test indicated no considerable difference before the program (P > 0.05) and a significant difference after the program (P < 0.001) between the two groups.

CONCLUSION: This family-need-based program can decrease the level of stress, anxiety, and depression of the family caregivers of leukemia patients and may potentially alleviate the psychological distress of family caregivers over their caring role.

ABSTRACT

PURPOSE: Haematopoietic stem cell transplantation (HSCT) is potentially lifesaving. However, it comes with negative consequences such as impaired physical functioning, fatigue and poor quality of life. The aim of this systematic review and meta-analysis is to determine the effect of exercise and nutrition interventions to counteract negative consequences of treatment and improve physical functioning in patients receiving HSCT.

METHODS: This systematic review and meta-analysis included randomised controlled trials from three electronic databases between 2009 and 2020. The trials included adult patients receiving HSCT and an exercise or nutrition intervention. Study selection, bias assessment and data extraction were independently performed by two reviewers. Physical functioning outcomes were meta-analysed with a random-effects model.

RESULTS: Thirteen studies were included using exercise interventions (n = 11) and nutrition interventions (n = 2); no study used a combined intervention. Meta-analysis of the trials using exercise intervention showed statistically significant effects on 6-min walking distance (standardised mean difference (SMD) 0.41, 95% CI: 0.14-0.68), lower extremity strength (SMD 0.37, 95% CI 0.12-0.62) and global quality of life (SMD 0.27, 95% CI: 0.08-0.46).

CONCLUSION: Our physical functioning outcomes indicate positive effects of exercise interventions for patients receiving HSCT. Heterogeneity of the exercise interventions and absence of high-quality nutrition studies call for new studies comparing different types of exercise studies and high quality studies on nutrition in patients with HSCT.

ABSTRACT

OBJECTIVE: The present study aimed to determine the factors affecting the use of cleaning products at the home environment and the frequency of problems during the COVID-19 pandemic.

MATERIALS AND METHODS: This cross-sectional research was performed online between 30.08.2020 and 15.09.2020. The population of the study consisted of adults aged between 18 and 80 years, affected by the COVID-19 pandemic. Data collection forms (Introductory Information and Risk Perception Form and Cleaning Products Usage Characteristics Form) were shared through Web2 tools. The questionnaire study was completed with 674 participants between the ages of 18 and 80 years in Turkey. Descriptive statistics and classification tree were used in the analysis of the data. Statistical significance was accepted as p≤0.01 in all analyses.

RESULTS: During the pandemic period compared to the pre-pandemic period, it was observed that the frequency of cleaning (69.3%) and the amount of cleaning product usage (74.2%) increased significantly and the frequency of problems related to the use of cleaning products was found as 46.9%. The most common reported problems were skin disturbances (68%) and shortness of breath (23%). It was determined that the history of contact with the COVID-19 patient, the perceived risk of COVID-19 infection and risky cleaning behavior were predictive in determining the risk of experiencing problems related to cleaning products. The amount of bleach consumed per month among who did experience problems was higher than those who did not experience problems and was associated with the perceived risk of COVID-19 infection.

CONCLUSION: In the COVID-19 pandemic, human beings have been found to increase the frequency of cleaning and using cleaning products. In order to reduce the negative effects of chemicals used for cleaning on human and environmental health, the trainings to be given by the teams providing primary health care services can be effective as well as general education activities for community groups.
