Systematic Review of Interventions for Demoralization in Patients With Cancer.

ABSTRACT: Demoralization as cancer-related mental health needs to be understood and addressed by clinical staff. This review systematically examined the characteristics and outcomes of interventions for demoralization in patients with cancer. Seven databases-PubMed, PsycINFO, Cinahl, Embase, Web of Science, Medline, and Cochrane Library Databases of Systematic Reviews-were systematically searched for relevant literature. We included intervention studies focusing on interventions for demoralization in patients with cancer. We ultimately included 14 studies. Overall, 10 studies had a positive effect on improving demoralization in patients with cancer, including two main types of interventions: psilocybin-assisted psychotherapy and psychological interventions. This review summarizes information on interventions for demoralization in patients with cancer. To provide precise care for demoralization in patients with cancer, future studies should use more rigorous methods to test interventions that may affect demoralization.

More Stable Memory Retention of Novel Words Learned from Fast Mapping than from Explicit Encoding.

There is a heated debate on a learning paradigm known as "fast mapping" for its early neocortical dependence and retained memory over time for amnesic patients with hippocampal system damage. Whether the fast mapping allows hippocampus independent learning and induces rapid integration is poorly understood. The present study aims to investigate the effect of fast mapping on very long-term retention, which to our knowledge has not been previously explored. We tested memory retention ranging from 10 min to 1.5 years, for novel word-object associations learned from fast mapping or explicit encoding procedures. The three-alternative forced choice recognition task was employed to assess memory performance. Besides the slight adjustment of the testing schedule, other settings remained the same in Experiment 2 to replicate and verify the findings of Experiment 1. Results showed that overall memory retrieval performance was higher after explicit encoding as compared to fast mapping. However, retrieval performance after explicit encoding dropped after 1.5 years, but remained stable in the fast mapping condition. Furthermore, matching the semantic category of the known and the novel items during the fast mapping paradigm might affect long-term retention. These results suggest that fast mapping creates more stable long-term memory representations as compared to the explicit encoding strategy.

"I'm walking on eggshells": challenges faced by mothers with breast cancer in interacting with adolescent daughters.

BACKGROUND: With breast cancer becoming the most diagnosed cancer in the world, the number of breast cancer-afflicted mothers with adolescent daughters is also rising. Further, adolescent daughters' mothers serve as role models for in identity formation processes, especially concerning gender and sexuality. Nevertheless, breast cancer threats mother's health, including such a key symbol of her womanhood-the breast-which may adversely affect the development of an adolescent daughter's own sense of personal identity and womanhood. However, few researchers and practitioners have paid attention to mother-daughter interactions in the context of breast cancer. Therefore, this study aimed to uncover the nuances of the interactive challenges with adolescent daughters from breast cancer-afflicted mothers' perspective. METHODS: We conducted a qualitative study following the sample saturation principle, collecting data through semi-structured interviews with 21 breast cancer patients who met the inclusion criteria. We utilized thematic analysis and partially integrated the Foucauldian discourse approach to analyze the data. RESULTS: Three major themes emerged from the data: (1) mothers are lost in chaos (inability to handle the shock of cancer, feelings of powerlessness about the uncertainty of their life span, and confusion about how to respond to daughter's curiosity); (2) mothers struggle to maintain balance (torn between protecting daughters and letting them be independent, and making a tough choice between being a mother or a patient); and (3) mothers are immersed in guilt (increasing daughters' risk of cancer, influencing daughters' development, and imposing burdens on daughters). CONCLUSIONS: Our research explored the interactive experience of breast cancer-afflicted mothers and adolescent daughters. The insights uncovered by this study will help mothers enhance interaction with their daughters and assist health practitioners in devising interventions.

The effect of maternal gestational diabetes on maternal and neonatal outcomes in twin pregnancies: a systematic review and meta-analysis.

Diabetes and twin pregnancies are known risk factors for poor perinatal and neonatal outcomes. However, the effects of these two entities occurring together are still unclear. PubMed, Scopus and Google Scholar databases were searched in a systematic manner to identify observational studies among twin pregnancies, which documented the association of gestational diabetes with maternal and neonatal outcomes. All the analysis was done using STATA software. The meta-analysis included 21 studies, of which majority were retrospective data based. Mothers with gestational diabetes had higher risks of hypertensive disorder in pregnancy, caesarean section, large for gestational age baby, NICU admission and neonatal hypoglycaemia compared to mothers without gestational diabetes. Diabetic mothers were at reduced risk of small for gestational age baby and low APGAR score. No statistically significant differences in the risk of low birth weight, mean birth weight, prematurity and neonatal death were noted. This meta-analysis observed increased risks of detrimental maternal, neonatal and perinatal outcomes in twin pregnancies complicated by gestational diabetes, underscoring the need for the early detection and management of gestational diabetes.

Microbiological impact of long-term wine grape cultivation on soil organic carbon in desert ecosystems: a study on rhizosphere and bulk sandy soils.

The improvement of nutrients in soil is essential for using deserts and decertified ecosystems and promoting sustainable agriculture. Grapevines are suitable crops for desert soils as they can adapt to harsh environments and effectively impact soil nutrients; however, the mechanisms underlying this remain unclear. This study explored the impact of the different duration(3, 6, and 10 years) of grape cultivation on soil organic carbon, physicochemical properties, enzyme activities, microbial communities, and carbon cycle pathways in both rhizosphere and bulk soils. Partial least squares path modeling was used to further reveal how these factors contributed to soil nutrient improvement. Our findings indicate that after long-term grape cultivation six years, soil organic carbon, total nitrogen, total phosphorus, microbial biomass carbon and nitrogen, and enzyme activities has significantly increased in both rhizosphere and bulk soils but microbial diversity decreased in bulk soil. According to the microbial community assembly analysis, we found that stochastic processes, particularly homogenizing dispersal, were dominant in both soils. Bacteria are more sensitive to environmental changes than fungi. In the bulk soil, long-term grape cultivation leads to a reduction in ecological niches and an increase in salinity, resulting in a decrease in soil microbial diversity. Soil enzymes play an important role in increasing soil organic matter in bulk soil by decomposing plant litters, while fungi play an important role in increasing soil organic matter in the rhizosphere, possibly by decomposing fine roots and producing mycelia. Our findings enhance understanding of the mechanisms of soil organic carbon improvement under long-term grape cultivation and suggest that grapes are suitable crops for restoring desert ecosystems.

Prevalence, Associated Factors and Adverse Outcomes of Demoralization in Cancer Patients: A Decade of Systematic Review.

Demoralization has been extensively studied in oncology and palliative care settings, and is characterized by a loss of meaning and purpose in life, a sense of powerlessness over life events, and a sense of helplessness. The objective of this systematic review is to synthesize the prevalence, associated factors, and adverse outcomes of demoralization in cancer patients by reviewing the literature of the last decade. Seven databases (PubMed, PsycINFO, Embase, Web of Science, Medline, CINAHL and Cochrane Library databases) were systematically searched from January 2012 to June 2022. Roughly speaking, the prevalence of demoralization in cancer patients ranges from 13.50% to 49.4%. A total of 45 factors are associated with demoralization, of which psychological factors have been studied more frequently in the last decade. There are nine outcomes related to demoralization, with the strongest evidence for the correlation between demoralization and suicidal ideation. The study emphasizes the complexity of factors associated with demoralization in cancer patients. There appears to be a intersection between the constructs of demoralization and depression, anxiety, and suicidal ideation, which may explain the correlation between them.

UV and visible Raman studies of oxygen vacancies in rare-earth-doped ceria.

Surface properties of rare-earth (RE) doped ceria (RE = Sm, Gd, Pr, and Tb) were investigated by UV (325 nm) and visible (514, 633, and 785 nm) Raman spectroscopy, combined with UV-vis diffuse reflectance spectroscopy, high-resolution transmission electron microscopy, and X-ray photoelectron spectra techniques. It was found that the optical absorption property of samples, the wavelength of detecting laser line, and the inhomogeneous distribution of the dopants significantly affected the obtained surface information, namely, the peak intensity and shape at ca. 460 and 570 cm(-1), as well as the observed oxygen vacancy concentration (A(570)/A(460)). The UV laser line detected the surface information of RE-doped ceria and disclosed the presence of many oxygen vacancies in the samples. The visible laser lines penetrated into the inner layer of the Sm- or Gd-doped CeO(2) and reflected the whole information of samples because of their weak absorptions of the visible laser. However, the Pr- or Tb-doped CeO(2) absorbed visible light strongly; thus, the laser can only determine the outer surface information of the sample.

Relationship of diabetes with renal dysfunction in hypertensive adults.

We aimed to examine the relationship of diabetes with the estimated glomerular filtration rate (eGFR)-based renal function in the Chinese hypertensive adults.This cross-sectional analysis included a total of 18,641 hypertensive adults aged 45 to 75 years. The relationship of diabetes (a fasting glucose ≥7.0 mmol/L or self-reported use of hypoglycemic agents or physician diagnosed diabetes) with glomerular hyperfiltration (an absolute eGFR >90th percentile after adjusting for sex, age), hypofiltration (an eGFR <10th percentile and ≥60 mL/min/1.73 m), and reduced eGFR (an eGFR <60 mL/min/1.73 m) were estimated by multiple logistic regressions.Both the cut-points for hyperfiltration and hypofiltration decreased with age increased, ranging from 115 to 91 mL/min/1.73 m and 91 to 67 mL/min/1.73 m, respectively. In the multiple logistic models, diabetes was positively associated with glomerular hyperfiltration (odds ratio [OR]: 2.19, 95% confidence interval [CI]: 1.93-2.47), hypofiltration (1.24, 1.05-1.46), and reduced eGFR (2.88, 2.21-3.76). Furthermore, the stronger association between diabetes and hyperfiltration was found in those with younger age (P for interaction <.001), or higher total cholesterol (TC) levels (P for interaction = .008). Consistently, significant association between diabetes and hypofiltration was only observed in participants with younger age (P for interaction = .043). And detrimentally interaction between diabetes and higher TC levels was also found (P for interaction <.001) on the risk of reduced eGFR.Diabetes was significantly associated with the impairment of renal function, particularly in those with younger age or with higher TC levels. Fasting glucose should be monitored as a marker to identify those with early renal dysfunction.

Changes in the cellular immune system and circulating inflammatory markers of stroke patients.

This study was designed to investigate dynamic changes in the cellular immune system and circulating inflammatory markers after ischemic stroke. Blood was collected from 96 patients and 99 age-matched control subjects for detection of lymphocyte subpopulations and inflammatory markers. We observed decreases in B cells, Th cells, cytotoxic T cells, and NK cells and an increase in regulatory T (Treg) cells in stroke patients on days 1, 3, and 7. Serum levels of TNF-α, C-reactive protein (CRP), IL-4, IL-6, IL-10, IL-17, IL-23, and TGF-ß increased, whereas serum level of IFN-γ decreased at all time points after stroke. Stroke patients with infection exhibited a similar tendency toward changes in some lymphocyte subpopulations and inflammatory markers as stroke patients without infection. After controlling for NIH Stroke Scale (NIHSS), we observed no differences in lymphocyte subpopulations between patients with anterior circulation stroke and those with posterior circulation stroke at any time point. The splenic volume correlated positively with the percentages of B cells, Th cells, and cytotoxic T cells, but negatively with Treg cells on day 3 after stroke. Infections were associated with splenic volume, leukocyte counts, percentage of Treg cells, and serum levels of CRP, IL-10, and IFN-γ on day 3. Lesion volume correlated positively with CRP, IL-6, and IL-23, but negatively with IFN-γ on day 3. The NIHSS showed a positive relation with IL-6 and IL-10 on day 3. Ischemic stroke has a profound effect on the systemic immune system that might explain the increased susceptibility of stroke patients to infection.
