Risk factors for carotid plaque formation in type 2 diabetes mellitus.

OBJECT: Patients with type 2 diabetes mellitus (T2DM) are at higher risk of developing atherosclerosis. Previous studies have analyzed the factors associated with diabetic macrovascular disease, although whether these factors are applicable to T2DM patients with carotid atherosclerosis remains unclear. Therefore, the aim of this study was to investigate the risk factors for the formation of carotid atherosclerotic plaque in hospitalized T2DM patients and to provide a theoretical basis for early prevention and treatment of carotid atherosclerosis in these patients. METHODS: A total of 949 patients with T2DM were included in the study. Carotid ultrasound identified 531 patients with carotid atherosclerotic plaque. The waist-to-hip ratio (WHR), blood glucose, liver and kidney function, blood lipid profile, islet function, and other indicators were measured at the same time to identify the risk factors and predictive significance of T2DM carotid plaque. RESULTS: The proportions of men, diabetes nephropathy (DN) and hypertension in T2DM patients with carotid plaque are higher than those without carotid plaque(P < 0.05). Age, duration of diabetes, WHR, Postprandial glucose (PPG), lipoprotein (a) [Lip (a)], carcinoembryonic antigen(CEA) and estimated glomerular filtration rate (eGFR) in T2DM patients with carotid plaque were higher than those without plaque (P < 0.05). Age, WHR, duration of diabetes, hypertension, males, and Lip (a) were independent risk factors for T2DM patients with carotid plaque. Age, WHR, duration of diabetes, and Lip (a) had a higher AUC to predict T2DM with carotid artery plaque (AUC: 0.750, 0.640, 0.678, 0.552 respectively; P all < 0.001). After constructing the logit (P) value of the above risk factors, the area under the ROC curve was 0.816 (0.789-0.842, P < 0.001). CONCLUSION: Age, WHR, duration of diabetes, hypertension, males, and Lip (a) levels are the main risk factors for the formation of carotid plaque in T2DM patients. Combining the above risk factors provides a better prediction of carotid plaque formation in T2DM.

TEMPO/O2 Synergistically Mediated BiBrO-Photocatalyzed Decarboxylative Phosphorylation of N-Arylglycines.

With both TEMPO and O2 (in air) as the homogeneous redox mediators, BiBrO as the heterogeneous semiconductor photocatalyst, the first example of semi-heterogeneous photocatalytic decarboxylative phosphorylation of N-arylglycines with diarylphosphine oxides was established. A series of α-amino phosphinoxides were efficiently synthesized.

Paired Electrolysis-Enabled Arylation of Quinoxalin-2(1H)-ones.

The first paired electrolysis-enabled arylation of quinoxalin-2(1H)-ones was achieved using cyanoarenes as the arylation reagents. A variety of 3-arylquinoxalin-2(1H)-ones with various important functional groups were obtained in moderate to good yields under metal- and chemical oxidant-free conditions. With a pair of reductive and oxidative processes occurring among the substrates and reaction intermediates, the power consumption can be dramatically reduced.

Electrochemical Multicomponent Cascade Reaction for the Synthesis of Selenazol-2-amines with Elemental Selenium.

The first example of an electrochemical multicomponent synthesis of selenium-containing compounds with inexpensive and abundant elemental selenium as the selenating reagent was developed. A variety of selenazol-2-amines were constructed in high yields with good functional group tolerance under metal-free and chemical oxidant-free conditions.

Delta-band neural tracking primarily reflects rule-based chunking instead of semantic relatedness between words.

It is debated whether cortical responses matching the time scales of phrases and sentences mediate the mental construction of the syntactic chunks or are simply caused by the semantic properties of words. Here, we investigate to what extent delta-band neural responses to speech can be explained by semantic relatedness between words. To dissociate the contribution of semantic relatedness from sentential structures, participants listened to sentence sequences and paired-word sequences in which semantically related words repeated at 1 Hz. Semantic relatedness in the 2 types of sequences was quantified using a word2vec model that captured the semantic relation between words without considering sentential structure. The word2vec model predicted comparable 1-Hz responses with paired-word sequences and sentence sequences. However, empirical neural activity, recorded using magnetoencephalography, showed a weaker 1-Hz response to paired-word sequences than sentence sequences in a word-level task that did not require sentential processing. Furthermore, when listeners applied a task-related rule to parse paired-word sequences into multi-word chunks, 1-Hz response was stronger than that in word-level task on the same sequences. Our results suggest that cortical activity tracks multi-word chunks constructed by either syntactic rules or task-related rules, whereas the semantic relatedness between words contributes only in a minor way.

Pain Intensity and Satisfaction of Pain Relief in Discharged Cancer Patients: A Large Sample Study in China.

BACKGROUND: Many studies have focused on the quality of pain management in hospitalized patients with cancer pain, while what happens after discharge remains unclear. AIM: The purpose of this study was to investigate the pain intensity and satisfaction of pain relief among a large sample of Chinese patients with cancer pain after discharge. DESIGN: Cross-sectional, descriptive, correlational research. SETTINGS AND SAMPLE: ABOUT: 1,013 patients were recruited in a tertiary cancer hospital, and their residence addresses were distributed in 6 geographical regions, including 26 provinces, municipalities, and autonomous regions. METHODS: The 1,013 patients with cancer pain were discharged from the wards of a national cancer hospital in China from July 2020 to October 2021. A nurse in the pain clinic followed the patients based on a whole-process information system and collected the data after the cancer pain patients were discharged. The study methods followed the STROBE guidelines. RESULTS: The average age of 1,013 discharged patients was 61.30 (±12.56) years. Moderate and severe background pain (BGP) was reported in 749 patients (73.94%), and more than 3 instances of breakthrough pain (BTP) in the past 24 hours were reported in 541 patients (53.41%). More severe BGP was associated with more frequent BTP (p < .01). In addition, there were 572 patients (56.47%) whose satisfaction with pain relief was lower than 70%. More severe BGP was associated with a lower satisfaction degree (r = -0.796, p < .01). CONCLUSIONS: Pain among discharged Chinese patients with cancer is poorly managed, and there is a low degree of satisfaction with pain relief. Nurses can do more work to assist cancer patients in managing pain more effectively by ensuring they have a plan to report and manage pain after discharge.

Selectfluor-Mediated Electrophilic Annulation of 2-Alkynyl Biaryls with Diorganyl Diselenides.

A general and efficient method for the synthesis of various selanyl phenanthrenes/polycyclic heteroaromatics through the electrophilic annulation of 2-alkynyl biaryls with diorganyl diselenides under metal-free and mild conditions was established. The sulfanyl phenanthrene was also obtained in moderate yields.

A Transparent Additive-Free Fibrous Facial Mask for Skin Moisturizing.

Most sheet facial masks for skincare are made of nonwovens and loaded with liquid active ingredients, which are usually opaque and require additives for long-term preservation. Herein, a Transparent Additive-Free Fibrous (TAFF) facial mask is reported for skin moisturizing. The TAFF facial mask consists of a bilayer fibrous membrane. The inner layer is fabricated by electrospinning functional components of gelatin (GE) and hyaluronic acid (HA) into a solid fibrous membrane to get rid of additives, the outer layer is an ultrathin PA6 fibrous membrane that is highly transparent, especially after absorbing water. The results indicate that the GE-HA membrane can quickly absorb water and become a transparent hydrogel film. By employing the hydrophobic PA6 membrane as the outer layer, directional water transport is achieved, which enables TAFF facial mask with excellent skin moisturizing effect. The skin moisture content is up to 84% ± 7% after placing the TAFF facial mask on the skin for 10 min. In addition, the relative transparency of the TAFF facial mask on the skin reaches 97.0% ± 1.9% when ultrathin PA6 membrane is used as the outer layer. The design of the transparent additive-free facial mask may serve as a guideline for developing new functional facial masks.

Delta-band neural activity primarily tracks sentences instead of semantic properties of words.

Human language is generally combinatorial: Words are combined into sentences to flexibly convey meaning. How the brain represents sentences, however, remains debated. Recently, it has been shown that delta-band cortical activity correlates with the sentential structure of speech. It remains debated, however, whether delta-band cortical tracking of sentences truly reflects mental representations of sentences or is caused by neural encoding of semantic properties of individual words. The current study investigates whether delta-band neural tracking of speech can be explained by semantic properties of individual words. Cortical activity is recorded using electroencephalography (EEG) when participants listen to sentences repeating at 1 Hz and word lists. The semantic properties of individual words, simulated using a word2vec model, predict a stronger 1 Hz response to word lists than to sentences. When listeners perform a word-monitoring task that does not require sentential processing, the 1 Hz response to word lists, however, is much weaker than the 1 Hz response to sentences, contradicting the prediction of the lexical semantics model. When listeners are explicitly asked to parse word lists into multi-word chunks, however, cortical activity can reliably track the multi-word chunks. Taken together, these results suggest that delta-band neural responses to speech cannot be fully explained by the semantic properties of single words and are potentially related to the neural representation of multi-word chunks.

Risk and main contributing factors for constipation in patients with gastrointestinal cancer: a multicenter cross-sectional study in China.

BACKGROUND AND OBJECTIVES: The purpose of this study is to determine the risk of constipation and to identify the significant risk factors for constipation in patients with gastrointestinal cancer using the Chinese version of the constipation risk assessment scale (CRAS-C), as well as to explore the complementary constipation risk factors in patients with gastrointestinal cancer, to improve the specificity of the CRAS-C in this population, and finally to provide a theoretical basis for constipation prevention. RESEARCH DESIGN AND METHODS: A cross-sectional study involving multiple centers was conducted. A total of 190 patients with gastrointestinal cancer completed surveys that included demographic information, defecation habits, and the CRAS-C. The mean, SD, median, maximum, minimum, frequency, and percentage were used as indicators for the constipation risk and significant risk factors. The t test and Chi-square tests were used to analyze constipation indicators in patients with gastrointestinal cancer. RESULTS: The mean (SD) age of the 190 participants was 61.68 (12.35) years. The total CRAS-C mean (SD) score was 13.22 (4.69). Fifty-one patients (26.8%) scored lower than 11, who were at the low-risk level of constipation. One hundred thirty-nine patients (73.2%) scored 11 or above, who were at the high-risk level of constipation. The top 10 factors were insufficient liquid intake (81.1%), failure to consume bran products daily (78.9%), insufficient fiber intake (77.9%), antiemetics (74.7%), cytotoxic chemotherapy (52.6%), colorectal/abdominal diseases (42.6%), female (35.3%), opioid analgesics(26.8%), calcium channel blockers (16.3%), and endocrine disorders (14.2%). Chi-square test showed that constipating for most of the past 3 months, ascites and ECOG score were complementary constipation risk factors in gastrointestinal cancer patients. CONCLUSION: The findings indicate that most gastrointestinal cancer patients were at a high risk of constipation. There are also several complementary constipation risk factors, and CRAS-C can be further revised in future studies to make it more specific in gastrointestinal cancer patients. Integrating CRAS into the pathway of constipation management, carrying out constipation risk screening for hospitalized cancer patients, and building systematic constipation prevention plan based on risk assessment are important to reduce the incidence of constipation in patients with gastrointestinal cancer and improve the quality of life.

Pain knowledge of patients and family caregivers as predictors of pain management outcomes in cancer patients: a multicenter study in China.

PURPOSE: The purposes of this study were to evaluate the current situation of pain management outcomes, patients' pain knowledge, and family caregivers' pain knowledge in China and explore the impact of pain knowledge of patients and family caregivers on pain management outcomes. METHODS: A total of 410 patient-family caregiver dyads were assessed by Brief Pain Inventory (BPI), the Pain Knowledge subscales of Patient Pain Questionnaire (PPQ), and Family Pain Questionnaire (FPQ). The difference in pain management outcomes was analyzed using bivariate analysis first, and then variables with statistical significance in bivariate analysis were included in multivariable linear regression analysis. RESULTS: The average patient pain score in the last 24 h was 3.23 (SD = 2.16). The total average scores on pain knowledge of 410 patients and family caregivers were 3.60 ± 1.90 and 3.57 ± 1.76. Multivariable linear regression analysis showed taking strong opioids, patients' perceived moderate health status, patients' pain knowledge, and family caregivers' pain knowledge were the main factors influencing the pain management outcomes. CONCLUSION: Pain knowledge of patients and family caregivers were important indicators of pain management outcomes, indicating tailored cancer pain education program should be developed.

A program to improve the knowledge, attitudes, and practices of needle stick and sharps injuries through bundled interventions among nurses: An KAP Mode-Based Approach to Intervention.

Nurses face a greater risk of needle stick and sharp injuries (NSIs) because they do most of the injections and procedures with sharp instruments. The current study tested a program to improve nurses' knowledge, attitudes and practices on NSIs, three phases were included: Developing the Hospital Practice Standard, implementing a series of measures and implementing of quality supervision phases. It consisted of a bundle of interventions based on Knowledge-Attitudes-Belief-Practice (KAP-KABP) Model with a pretest-posttest design. We obtained a total of 656 (88.53%) completed pre-intervention questionnaires and 674 (92.97%) post-intervention ones. The number of trained participants on NSIs increased from 615 (93.7%) to 666 (98.8%), and reported of NSIs within 3 months decreased from 42 to 15 (2.2%) after the intervention. The total score of Knowledge of NSIs improved from 19.18 (SD = 1.31) to 19.42 (SD = 0.93) after training (Z = -4.025, P < 0.001), the Attitude was raised from 54.21 (SD = 4.09) to 55.24 (SD = 3.59) (Z = -5.261, P < 0.001), and the Practice increased from 89.28 (SD = 7.22) to 92.74 (SD = 7.22), with a P Value<0.05. The findings indicated the program can improve the nurses' knowledge and attitudes towards NSIs prevention. There is a statistically significant increase in the practice score and decrease in the incidence rate of NSIs after the intervention.

Risk-Taking Behavior Among Male Adolescents: The Role of Observer Presence and Individual Self-Control.

A number of studies have focused on the same-sex peer effect on and the developmental difference in adolescent risk-taking in terms of the dual systems model. Little research, however, addresses the effects of different observers, the role of different levels of individual self-control, and their interactions. To fill this gap, the present study examined the main and interactive effects of observer presence and individual self-control on male adolescents' risk-taking behavior with an experimental design. A total of 261 male adolescents (Mage = 15.79 ± 0.79, range = 14-18) completed an adapted Stoplight Task, which measures risk-taking behavior, in the presence of an observer, either peer or adult, either male or female. The results indicated that a same-sex peer's presence and low self-control were both risk factors of male adolescents' risk-taking, but did only low self-control male adolescents take serious risks when in the presence of a same-sex peer whereas those with high self-control consistently had low levels of risk-taking under any condition. An opposite-sex observer, particularly an opposite-sex adult's presence, played a similar protective role for male adolescents with low self-control. The findings suggest that a high level of self-control closely related to the cognitive control system may significantly buffer the negative effect of an adverse social stimulus which activates the social-emotional system on male adolescents' risk-taking; the findings also reveal that an opposite-sex adult's presence may contribute to a decrease in male adolescents' risk-taking by improving their cognitive control system.

Structural Equation Model of Factors Related to Death Anxiety for Chinese Patients with Cancer.

This study aimed to develop a model that specifies the predictive effects of factors on death anxiety among Chinese patients with cancer using structural equation modeling. Using convenience sampling, data were collected from 353 cancer patients. Self-administered questionnaires included Social Support Rating Scale, Rosenberg Self-Esteem Scale, Connor Davidson Resilience Scale, Templer's Death Anxiety Scale, and socio-demographic factors. The results showed that social support, self-esteem, and resilience significantly impacted death anxiety. The final model fitted the data acceptably (χ2 = 37.319, df =31, p = 0.201). Social support mediated death anxiety through self-esteem and resilience. Resilience mediated the buffer effect of self-esteem on death anxiety as an intermediary factor. Findings suggest the need for further studies to explore effective interventions to provide social support and improve self-esteem and resilience among patients with cancer to alleviate death anxiety.

Congruence of cancer pain experience between patients and family caregivers and associated factors: a multicenter cross-sectional study in China.

PURPOSE: The purposes of this study were to determine whether there were differences in the cancer pain experience between patients and family caregivers (FCGs) and to explore the associated factors that influence cancer pain experience congruence. METHODS: A multicenter cross-sectional study was conducted. A total of 410 patient-family caregiver dyads completed face-to-face surveys, including information about basic characteristics, the Patient Pain Questionnaire (PPQ), and the Family Pain Questionnaire (FPQ). The difference in cancer pain experience between patients and family caregivers was analyzed using a paired t test. Indicators for the congruence of cancer pain experience were analyzed using the chi-square test and two independent-sample t tests for bivariate analysis and multivariate binary logistic regression analysis. RESULTS: Of the patients, 57.1% were men, and 60.7% perceived moderate performance status. The majority of the family caregivers was female (54.9%). The mean (SD) score on the pain experience subscale was 4.82 (1.66) for 410 patients and 5.02 (1.66) for 410 family caregivers. The difference was significant (P < 0.01). Additionally, 87 (21.2%) dyads were in the congruent group, and 323 (78.8%) dyads were in the incongruent group. Patients' self-perceived moderate performance status (OR = 2.983, P < 0.01) and family caregivers' pain knowledge (OR = 1.171, P < 0.05) were the main factors influencing the congruence of cancer pain experience. CONCLUSION: The findings of this study indicate that family caregivers reported significantly worse cancer pain experiences than patients. Family caregivers' pain knowledge was a primary influencing factor. It is suggested that educational interventions aimed at teaching family caregivers and patients how to communicate their pain experience and improving the knowledge of family members regarding pain and its management may help in aligning their perceptions and thereby contribute to better quality of life and pain management outcomes.

Knowledge and Attitudes of Chinese Oncology Nurses Regarding Cancer Pain Management-a Cross-Sectional Study.

OBJECTIVE: To measure the knowledge and attitudes of Chinese oncology nurses regarding cancer pain management and explore related factors. METHODS: A cross-sectional survey was conducted. A convenience sample of 505 Chinese oncology nurses from 20 provinces, 4 municipalities, and 4 autonomous regions was recruited between April and October 2018. A Chinese version of the Knowledge and Attitudes Survey Regarding Pain (KASRP) was used. Socio-demographic characteristics were also measured by a multi-item questionnaire. RESULTS: The mean accuracy of KASRP in all participants was 56.11% ± 11.05%. According to univariate analysis, oncology nurses' cancer pain knowledge and attitudes were positively correlated with age, region, education level, years of oncology nursing, clinical practice of cancer pain management, average monthly number of patients with cancer pain, and the experience of cancer pain-related training. The results of multiple linear regression revealed that nurses' age, education level, experience of cancer pain-related training and clinical practice of cancer pain management were independent influencing factors (all p < 0.05). CONCLUSIONS: Most Chinese oncology nurses had misconceptions about cancer pain management and lacked relevant knowledge. We should assign importance to targeted cancer pain training and develop training methods that closely relate to clinical practices.

The Knowledge and Attitude Towards Advance Care Planning Among Chinese Patients with Advanced Cancer.

To describe the knowledge and attitude of Chinese patients with advanced cancer towards advanced care planning (ACP), a convenience sample of 275 patients with advanced cancer was recruited from a tertiary cancer hospital in Beijing, China, between February and December 2017. The multi-item questionnaire focused on patients' demographics, disease characteristics and knowledge about and attitude towards ACP and was administered to eligible patients. Descriptive statistics were performed. Most patients had never heard about ACP (82.2%) and had never talked about ACP (83.0%), but only a few (18.3%) were not willing to talk about ACP. A total of 67.8% patients chose to refuse resuscitation attempts or life-sustaining medical interventions, and 70.8% of patients hoped to have surrogate decision makers when they became unconscious. By binary logistic regression analysis, patients who were of greater age, female and living in urban areas preferred to refuse resuscitation attempts or life-sustaining medical interventions (OR = 1.023, P = 0.042; OR = 2.011, P = 0.020; OR = 0.254, P < 0.01); patients who had very rich or rich family economic status preferred to involve surrogate decision makers compared with patients of very poor family economic status (OR = 0.250, P = 0.011). There is a large gap between the knowledge about ACP and the expectation of implementing ACP in Chinese patients with advanced cancer. To develop culturally appropriate and individualized programmes to promote knowledge and implementation in practice of ACP among Chinese patients with advanced cancer and their relatives is still a significant challenge.

Post-traumatic growth and related factors among 1221 Chinese cancer survivors.

OBJECTIVE: There is an increasing number of studies on the post-traumatic growth (PTG) of cancer survivors worldwide. However, few Chinese studies have reported about PTG in cancer survivors because of the underdevelopment of community health services. This study aimed to evaluate the level of PTG in China and explore related factors among a large sample of survivors of more than 12 cancer types. METHODS: We recruited 1236 survivors from 14 sites of the Beijing Cancer Rehabilitation Association. Survivors completed standardized questionnaires assessing PTG, social support, coping styles, demographic characteristics, and clinical conditions. Multivariate linear regression was used to evaluate potential predictive factors of PTG. RESULTS: A total of 1221 (98.7%) subjects completed the questionnaires. The average PTG score was 61.15 ± 20.26. Seven variables were included in the final regression model: social support, coping style, time after treatment, exercise, BMI, work status, and economic income (P < .05). Survivors who had low levels of social support, had negative coping strategies, had a time after treatment of less than 5 years, exercised irregularly, had an abnormal BMI, were unemployed, or had low economic income had lower PTG levels. CONCLUSIONS: PTG levels among Chinese cancer survivors are associated with social support, coping style, time after treatment, exercise, BMI, work status, and economic income. Strategies tailored to Chinese survivors should be developed to promote their PTG and improve their physical and psychological well-being.

Relationships between patient-related attitudinal barriers, analgesic adherence and pain relief in Chinese cancer inpatients.

PURPOSE: The purpose of this study was to evaluate patient-related attitudinal barriers and identify associated factors in Chinese cancer inpatients receiving opioids and to explore relationships between patient-related attitudinal barriers, analgesic adherence and pain relief. METHODS: A cross-sectional study was conducted. A total of 146 participants completed face-to-face surveys, including information about demographics, the Barriers Questionnaire-Chinese (BQ-C), analgesic adherence, average pain and breakthrough pain in the past 24 h. The Mann-Whitney U test and Kruskal-Wallis test were performed to test the differences in the attitudinal barrier scores between the adherence and nonadherence groups, the complete and incomplete pain relief groups and the groups based on demographics. RESULTS: The majority of participants in this study were men (67.8%), over half of all participants were less than 60 years old, gastrointestinal cancer (47.3%) was the most common diagnosis and 59 (40.4%) acquired comprehensive pain education from the last discharge guidance procedure. The total BQ-C mean (SD) score was 1.61 ± 0.94. A total of 87 (59.6%) patients with cancer pain were completely relieved. Most of the patients (73.3%) completely took analgesics by orders. There was no significant difference in the total BQ-C score between the adherence group and the nonadherence group (P > 0.05), but the difference was significant between the complete pain relief group and the incomplete pain relief group (P < 0.05). CONCLUSION: The findings of this study support unsatisfactory pain management and moderate analgesic adherence for Chinese inpatients. It is suggested that patient-related attitudinal barriers do not play an undermining role in pain management by negatively affecting patients' analgesic adherence. Conversely, patients' beliefs are more likely to be shaped by under treatment rather than as a cause.

Nurse-rated good death of Chinese terminally ill patients with cancer: A cross-sectional study.

OBJECTIVE: To explore the good death of terminally ill patients with cancer rated by nurses and identify associated factors in the context of Chinese culture. METHODS: We conducted a cross-sectional, anonymous questionnaire survey. Totally, convenience samples of 122 nurses in charge of 258 patients during their dying period were investigated. The questionnaire consisted nurses' information including demographics and the experience in palliative care, patients' demographic information and disease characteristics, and Good Death Inventory (GDI). RESULTS: Two hundred and fifty-eight (98.10%) analysable questionnaires were obtained. The total good death score was (245.40 ± 36.91), and the last three were "Independence" (7.34 ± 4.26), "Physical and psychological comfort" (8.12 ± 4.70) and "Religious and spiritual comfort" (8.44 ± 4.55); the first three were "Being respected as an individual" (18.31 ± 2.90), "Good relationship with medical staff" (18.26 ± 2.37) and "Natural death" (18.16 ± 3.22). The unit type, treatment patients received during their last 3 months and nurse's training experience in palliative care were associated factors of good death (R2  = 0.135, F = 9.160, p < .001). CONCLUSION: The good death status of terminally ill cancer patients is poor. It's urgent to promote palliative care and strengthen the training about the knowledge and skills to improve the quality of life of the patients, so as to achieve the goal of good death.
