RESUMO

AIMS: Glucagon-like peptide-1 receptor agonist (GLP-1RA) may promote bone formation, but conversely, they could also weaken bones due to the reduction in mechanical load associated with weight loss. However, the clinical effects in humans have not been clearly demonstrated. This meta-analysis aimed to evaluate whether GLP-1RAs affect BMD and bone turnover markers. MATERIAL AND METHODS: PubMed, Embase, and Scopus were searched on June 13, 2024. The eligibility criteria were: (1) human studies, (2) receiving a GLP-1RA for more than 4 weeks, (3) an untreated control group or a placebo group, (4) reporting of at least one BMD or bone turnover marker, and (5) an RCT design. The risk of bias was assessed using the Cochrane risk of bias 2 tool. Fixed- or random-effects meta-analysis was performed according to heterogeneity. RESULTS: Seven studies were included in the meta-analysis. GLP-1RAs did not significantly change BMD in the femoral neck (mean difference [MD], 0.01 g/cm2; 95% CI, -0.01-0.04 g/cm2), in the total hip (MD, -0.01 g/cm2; 95% CI, -0.02-0.01 g/cm2), and in the lumbar spine (MD, 0 g/cm2; 95% CI, -0.02-0.02 g/cm2). C-terminal telopeptide of type 1 collagen (CTX), a bone resorption marker, significantly increased after GLP-1RA treatment (MD, 0.04 µg/L; 95% CI, 0.01-0.07 µg/L). GLP-1RAs did not significantly change bone formation markers such as procollagen type 1 N-terminal propeptide, bone-specific alkaline phosphatase, osteocalcin. CONCLUSIONS: GLP-1RA did not affect BMD and bone formation markers. However, GLP-1RAs led to a significant increase in CTX.

RESUMO

Even though EUV lithography has the advantage of implenting a finer pattern compared to ArF immersion lithography due to the use of 13.5 nm instead of 193 nm as the wavelength of the light source, due to the low energy of EUV light source, EUV resist has a thinner thickness than conventional ArF resist. EUV resist having such a thin thickness is more vulnerable to radiation damage received during the etching because of its low etch resistance and also tends to have a problem of low etch selectivity. In this study, the radiation damage to EUV resist during etching of hardmask materials such as Si3N4, SiO2, etc using CF4gas was compared between neutral beam etching (NBE) and ion beam etching (IBE). When NBE was used, after the etching of 20 nm thick EUV resist, the line edge roughness increase and the critical dimension change of EUV resist were reduced by ∼1/3 and ∼1/2, respectively, compared to those by IBE. Also, at that EUV etch depth, the root mean square surface roughness value of EUV resist etched by NBE was ∼2/3 compared to that by IBE on the average. It was also confirmed that the etching selectivity between SiO2, Si3N4, etc and EUV resist was higher for NBE compared to IBE. The less damage to the EUV resist and the higher etch selectivity of materials such as Si3N4and SiO2over EUV resist for NBE compared to IBE are believed to be related to the no potential energy released by the neutralization of the ions during the etching by NBE.

RESUMO

PURPOSE: This study aimed to evaluate the impact of multimodal postoperative pain management, performing a surgical rectus sheath (RS) block via ropivacaine injection into the surgical field after single-incision laparoscopic appendectomy (SILA). METHODS: Patients who underwent single-incision laparoscopic appendectomy (SILA) for acute appendicitis were divided into three groups and compared: group 1 (multimodal pain management that included intraoperative application of a surgical RS block), group 2 (conventional pain management with intravenous opioids), or group 3 (multimodal pain management without RS block). Forty, 53, and 42 patients were registered, respectively (Table 1). RESULTS: Time to start a liquid (1.2 ± 0.4 h) in group 1 was statistically significantly shorter than that in group 2 (16.3 ± 8.4 h; p < 0.001) and group 3 (4.93 ± 2.3 h; p < 0.001). The median and max postoperative VAS scores in group 1 (1.6 ± 1.2 and 2.2 ± 1.8, respectively) were statistically significantly lower than that in group 2 (3.0 ± 1.2 and 4.2 ± 1.9, respectively; p < 0.001 on both accounts) and group 3 (2.9 ± 0.6 and 3.4 ± 1.2, respectively; p < 0.001 on both accounts). The postoperative hospital stay for group 1 (17.0 ± 9.4 h) was shorter than that for group 2 (44.7 ± 27.9 h; p < 0.001) and group 3 (35.4 ± 20.9 h; p < 0.001). RS block was a significant factor for reducing length of hospital stay and postoperative pain in 24 h. CONCLUSIONS: A surgical RS block combined with multimodal pain management after SILA is a safe and effective method that results in reduced postoperative pain and shorter hospitalization.

RESUMO

OBJECTIVES: This systematic review of longitudinal studies, assessing subjective cognitive impairment (SCI) reported by adult cancer patients, aimed to summarize evidence on the impact of chemotherapy on SCI, identify moderators of SCI, and evaluate methodological issues. METHODS: Data accrued from Pubmed, EMBASE, CINAHL, PsychInfo, and the Cochrane library. Inclusion criteria were original studies, an exclusively adult sample, valid and reliable subjective cognitive measures, and at least one baseline data point prior to and another after the initiation of chemotherapy. Data were collected on the sample composition, data-collection time points, outcome measures, statistical analysis, and major findings (ie, longitudinal changes in prevalence, severity, and associated factors). RESULTS: Forty articles published between 2004 and 2019 were retained: 21 examined chemotherapy-treated patients only, and 19 employed control groups. Findings were mixed, with slightly more studies supporting the impact of chemotherapy on SCI. SCI tended to be more prevalent and severe after initiating chemotherapy, compared with patients' own baseline and controls not treated with chemotherapy. Impact appeared to be acute and more likely limited to subsamples. Most studies examining non-breast-cancer samples reported the lack or limited impact of chemotherapy on SCI. The most consistent moderators were depression and fatigue. Methodological issues regarding sampling design, measurement, and statistical analysis were discussed. CONCLUSION: More rigorously designed longitudinal studies would clarify direct and indirect effects of chemotherapy on SCI.

RESUMO

AIMS AND OBJECTIVES: To evaluate the psychometric quality of two single-item pain-intensity measures: the Numeric Rating Scale (NRS) and the Verbal Rating Scale (VRS). BACKGROUND: Measuring pain intensity is a vital step in initiating symptom management and evaluating the effectiveness of interventions with cancer patients. Single-item pain-intensity measures of the NRS and VRS format have been evaluated to be acceptable for use in clinical practice and research; however, evidence to choose one over the other, as a standardised pain-assessment format, is insufficient. DESIGN: Descriptive correlational study. The study was guided and reported following the STROBE guideline. METHODS: Data accrued at two time points during cancer treatment with a total of 249 patients treated in a Korean University Hospital. Two single-item measures were constructed to assess pain intensity over 1 week. The Brief Pain Inventory (BPI; pain intensity subscale and interference subscale) and the functional assessment of chronic illness therapy-fatigue were the criterion. Convergent and concurrent validity were tested with Pearson's correlations. RESULTS: In the convergent-validity evaluation of the cross-sectional association with the BPI, the NRS showed a much higher level of association than the VRS (0.81 versus 0.61). In convergent validity with a longitudinal association with the BPI, the NRS score change had a much higher level of association (0.61 versus 0.37). In concurrent-validity evaluation, the NRS and VRS showed similar levels of associations with fatigue (-0.48 versus -0.49). Yet, the NRS showed statistically higher levels of correlation with functional limitations than the VRS (0.55 versus 0.42), comparable to the concurrent validity of the BPI. CONCLUSION: The NRS showed higher validity than VRS when assessing overall pain intensity over the past week. RELEVANCE TO CLINICAL NURSING: Pain assessment is a vital role of nurses in caring for patients with cancer. Current study findings support the use of the single-item NRS pain measure to assess global pain intensity over the past week.

RESUMO

OBJECTIVE: To identify those experiencing significant self-reported cognitive decline over 2 time points during chemotherapy, examine the risk factors for cognitive decline, and examine differences between those with and without significant decline in functional limitations. METHODS: This secondary analysis used data from 163 cancer patients, collected from a Korean University hospital. Significant decline was determined by 15% or more reduction from baseline in the Functional Assessment of Cancer Therapy-Cognitive Function. Multivariate logistic regression was performed to estimate risk factors. Repeated-measures ANOVA and t tests tested differences in groups with and without cognitive decline in cognitive impairment and functional limitation. RESULTS: About 31% (n = 51) experienced significant cognitive decline. Groups with and without decline significantly differed in cognitive-impairment changes over time (F = 238.49, P < .001) and in functional limitations at follow-up (t test, P < .01). Those experiencing increased fatigue over time (odds = 0.94, P < .05) and those who underwent 2 or more cycles between time 1 and 2 (odds = 2.61; P < .05) had higher risk of significant decline over time during chemotherapy. CONCLUSION: Significant cognitive decline occurred during active chemotherapy; attention to cognitive impairment should be given in the early phase of chemotherapy.

RESUMO

PRF001 is a fragmented DNA polymer extracted from the testes of salmon. The purpose of this study was to assess the anti-inflammatory effect of PRF001 in vitro as well as the protective effect of PRF001 intake against arthritis in a rat model. In vitro, cell survival and inflammatory markers after H2O2 treatment to induce cell damage were investigated in CHON-001 cells treated with different concentrations of PRF001. In vivo, osteoarthritis was induced by intra-articular injection of monosodium iodoacetate (MIA) into the knee joints of rats. After consumption of PRF001 (10, 50, or 100 mg/kg) for 4 weeks, inflammatory mediators and cytokines in articular cartilage were investigated. In vitro, the levels of inflammatory markers, IL-1ß, TNF-α, COX-2, iNOS, and PGE2, were significantly suppressed by PRF001 treatment. In vivo, the inflammatory mediators and cytokines, IL-1ß, p-Erk1/2, NF-κB, TNF-α, COX-2, and PGE2, as well as MMP3 and MMP7, which have catabolic activity in chondrocytes, were decreased in the MIA-induced osteoarthritic rats following intake of PRF001. Histological analysis revealed that PRF001 had a protective effect on the articular cartilage. Altogether, these results demonstrated that the anti-inflammatory property of PRF001 contributes to its protective effects in osteoarthritis through deregulating IL-1ß, TNF-α, and subsequent signals, such as p-Erk1/2, NF-κB, COX-2, PGE2, and MMPs.

RESUMO

This study was designed to evaluate the reliability (internal consistency, reproducibility over time, and measurement precision) and validity (factorial, convergent, and concurrent validity) of the 4-item Korean Perceived Stress Scale in comparison to the 10-item Korean Perceived Stress Scale. Participants were 650 students from seven schools of nursing in South Korea. Measures included Korean versions of the Perceived Stress Scale, the Pittsburgh Sleep Quality Index, and a single-item quality-of-life measure. The 4-item Perceived Stress Scale had lower Cronbach alpha than the 10-item Perceived Stress Scale (.65 vs. .80), but its item-total correlations (.35-.47) and split-half coefficient (.81) were comparable to the 10-item Perceived Stress Scale (item-total correlations = .20-.56; split-half coefficient = .82). Reproducibility of the 4-item scale after a 1-week interval (r = .67, ICC absolute agreement = .64) was similar to the 10-item scale (r = .70, ICC absolute agreement = .65). The standard error of measurement was slightly higher in the 4-item scale. Scale constructs of the two were identical in exploratory factor analysis. The two scales were highly correlated (r = .93) and showed similar levels of concurrent validity with sleep quality and quality of life. In conclusion, the 4- and 10-item Korean Perceived Stress Scale are similar in psychometric qualities. © 2016 Wiley Periodicals, Inc.

RESUMO

BACKGROUND AND OBJECTIVES: Dysregulation of the autophagy pathway has been suggested as an important mechanism in the pathogenesis of Parkinson's disease (PD). Therefore, modulation of autophagy may be a novel strategy for the treatment of PD. Recently, an active form of vitamin D3 has been reported to have neuroprotective properties. Therefore, we investigated the protective, autophagy-modulating effects of 1,25-dyhydroxyvitamin D3 (calcitriol) in an in vitro model of Parkinson's disease. METHODS: An in vitro model of Parkinson's disease, the rotenone-induced neurotoxicity model in SH-SY5Y cells was adapted. We measured cell viability using an MTT assay, Annexin V/propidium iodide assay, and intracellular reactive oxygen species levels and analyzed autophagy-associated intracellular signaling proteins by Western blotting. RESULTS: Rotenone treatment of SH-SY5Y cells reduced their viability. This treatment also increased reactive oxygen species levels and decreased levels of intracellular signaling proteins associated with cell survival; simultaneous exposure to calcitriol significantly reversed these effects. Additionally, calcitriol increased levels of autophagy markers, including LC3, beclin-1, and AMPK. Rotenone inhibited autophagy, as indicated by decreased beclin-1 levels and increased mTOR levels, and this effect was reversed by calcitriol treatment. DISCUSSION: Calcitriol protects against rotenone-induced neurotoxicity in SH-SY5Y cells by enhancing autophagy signaling pathways such as those involving LC3 and beclin-1. These neuroprotective effects of calcitriol against rotenone-induced dopaminergic neurotoxicity provide an experimental basis for its clinical use in the treatment of PD.

RESUMO

α-Viniferin is an oligostilbene of trimeric resveratrol and has anticancer activity; however, the molecular mechanism underlying the anti-inflammatory effects of α-viniferin has not been completely elucidated thus far. Therefore, we determined the mechanism by which α-viniferin regulates lipopolysaccharide (LPS)-induced expression of proinflammatory mediators in BV2 microglial cells. Treatment with α-viniferin isolated from Clematis mandshurica decreased LPS-induced production of nitric oxide (NO) and prostaglandin E2 (PGE2). α-Viniferin also downregulated the LPS-induced expression of proinflammatory genes such as iNOS and COX-2 by suppressing the activity of nuclear factor kappa B (NF-κB) via dephosphorylation of Akt/PI3K. Treatment with a specific NF-κB inhibitor, pyrrolidine dithiocarbamate (PDTC), indirectly showed that NF-κB is a crucial transcription factor for expression of these genes in the early stage of inflammation. Additionally, our results indicated that α-viniferin suppresses NO and PGE2 production in the late stage of inflammation through induction of heme oxygenase-1 (HO-1) regulated by nuclear factor erythroid 2-related factor (Nrf2). Taken together, our data indicate that α-viniferin suppresses the expression of proinflammatory genes iNOS and COX-2 in the early stage of inflammation by inhibiting the Akt/PI3K-dependent NF-κB activation and inhibits the production of proinflammatory mediators NO and PGE2 in the late stage by stimulating Nrf2-mediated HO-1 signaling pathway in LPS-stimulated BV2 microglial cells. These results suggest that α-viniferin may be a potential candidate to regulate LPS-induced inflammation.

RESUMO

Neutropenic sepsis (NS) is one of the leading causes of death among patients with hematologic malignancies. Identifying its predictive factors is fundamental for early detection. Few studies have evaluated the predictive factors in relation to microbial infection confirmation, which is clinically important for initiating sepsis treatment. This study aimed to determine whether selected biomarkers (i.e., body temperature, C-reactive protein, albumin, procalcitonin), treatment-related characteristics (i.e., diagnosis, duration of neutropenia, treatment modality), and infection-related characteristics (i.e., infection source, causative organisms) can predict NS in patients with hematologic malignancies. We also aimed to identify the optimal predictive cutoff points for these parameters. This retrospective case-control study used the data from a total of 163 patients (58 in the sepsis group and 105 in the non-sepsis group). We collected data with reference to the day of specimen collection, with which microbial infection was confirmed. Multiple logistic regression was used to determine predictive risk factors and the area under the curve (AUC) of the receiver operating characteristic for the optimal predictive cutoff points. The independent predictors of NS were average body temperature during a fever episode and procalcitonin level. The odds for NS rose by 9.97 times with every 1°C rise in average body temperature (95% confidence interval, CI [1.33, 75.05]) and by 2.09 times with every 1 ng/mL rise in the procalcitonin level (95% CI [1.08, 4.04]). Average body temperature (AUC = 0.77, 95% CI [0.68, 0.87]) and procalcitonin levels (AUC = 0.71, 95% CI [0.59, 0.84]) have fair accuracy for predicting NS, with the optimal cutoff points of 37.9°C and 0.55 ng/mL, respectively. This study found that average body temperature during a fever episode and procalcitonin are useful in predicting NS. Thus, nurses should carefully monitor body temperature and procalcitonin levels in patients with hematologic malignancies to detect the onset of NS.

RESUMO

Obesity is primarily exacerbated by excessive lipid accumulation during adipogenesis, with triacylglycerol (TG) as a major lipid marker. However, as the association between numerous lipid markers and various health conditions has recently been revealed, investigating the lipid metabolism in detail has become necessary. This study investigates the lipid metabolic effects of Hydrangea serrata (Thunb.) Ser. hot water leaf extract (WHS) on adipogenesis using LC-MS-based lipidomics analysis of undifferentiated, differentiated, and WHS-treated differentiated 3T3-L1 cells. WHS treatment effectively suppressed the elevation of glycerolipids, including TG and DG, and prevented a molecular shift in fatty acyl composition towards long-chain unsaturated fatty acids. This shift also impacted glycerophospholipid metabolism. Additionally, WHS stabilized significant lipid markers such as the PC/PE and LPC/PE ratios, SM, and Cer, which are associated with obesity and related comorbidities. This study suggests that WHS could reduce obesity-related risk factors by regulating lipid markers during adipogenesis. This study is the first to assess the underlying lipidomic mechanisms of the adipogenesis-inhibitory effect of WHS, highlighting its potential in developing natural products for treating obesity and related conditions. Our study provides a new strategy for the development of natural products for the treatment of obesity and related diseases.

RESUMO

In this study, the effects of Cl2 radicals on dry development of spin-coated metal oxide resist (MOR) and changes in its surface binding states were investigated to verify the mechanism of dry development. Dry development characteristics of tin hydroxide (Tin OH), which is one of the MOR candidates for next generation lithography, were investigated as functions of process time and temperature using a Cl2 radicals source. Non-UV-exposed Tin OH film showed a linear etch rate (1.77 nm/min) from the initial thickness of ∼50 nm, while the UV-exposed film showed slower etch behavior (1.46 nm/min) in addition to the increase of film thickness for up to 3 min during the Cl2 radical dry development. UV-exposed photoresist (PR) contained more oxygen (Sn-O bonding) in the film due to the removal of butyl compounds from the clusters during the UV exposure process. Therefore, due to the lower reaction of chlorine radicals with Sn-O in the UV-exposed Tin OH than the other bindings, the non-UV-exposed PR was preferentially removed compared to the UV-exposed PR. As the temperature decreases, the overall etch rate decreases, but the difference in etch rate between exposed and unexposed Tin OH becomes larger. Finally, at a substrate temperature of -20 °C, the non-UV-exposed Tin OH with a thickness of 50 nm was completely removed, while ∼30 nm thick PR remained for UV-exposed Tin OH. Eventually, a negative tone development was possible with Cl2 radical plasma due to the difference in activation energy between the UV-exposed and non-UV-exposed films. It is believed that dry development using Cl2 radicals will be one of the most important process techniques for next-generation patterning to remove problems such as pattern leaning, line edge roughness, residue, etc., caused by wet development.

RESUMO

Asthma is a chronic inflammatory disorder of the lungs that results in airway inflammation and narrowing. BS012 is an herbal remedy containing Asarum sieboldii, Platycodon grandiflorum, and Cinnamomum cassia extracts. To elucidate the anti-asthma effect of BS012, this study analyzed the immune response, respiratory protection, and changes in metabolic mechanisms in an ovalbumin-induced allergic asthma mouse model. Female BALB/c mice were exposed to ovalbumin to induce allergic asthma. Bronchoalveolar lavage fluid and plasma were analyzed for interleukin and immunoglobulin E levels. Histological analyses of the lungs were performed to measure morphological changes. Apoptosis-related mediators were assayed by western blotting. Plasma and lung tissue metabolomic analyses were performed to investigate the metabolic changes. A T-helper-2-like differentiated cell model was used to identify the active components of BS012. BS012 treatment improved inflammatory cell infiltration, mucus production, and goblet cell hyperplasia in lung tissues. BS012 also significantly downregulated ovalbumin-specific immunoglobulin E in plasma and T-helper-2-specific cytokines, interleukin-4 and -5, in bronchoalveolar lavage fluid. The lungs of ovalbumin-inhaled mice exhibited nerve growth factor-mediated apoptotic protein expression, which was significantly attenuated by BS012 treatment. Ovalbumin-induced abnormalities in amino acid and lipid metabolism were improved by BS012 in correlation with its anti-inflammatory properties and normalization of energy metabolism. Additionally, the differentiated cell model revealed that N-isobutyl-dodecatetraenamide is an active component that contributes to the anti-allergic properties of BS012. The current findings demonstrate the anti-allergic and respiratory protective functions of BS012 against allergic asthma, which can be considered a therapeutic candidate.

RESUMO

Background: Skin pigmentation after adrenalectomy occurs due to an increase in adrenocorticotropic hormone (ACTH) following adrenal insufficiency. ACTH-induced pigmentation usually appears as generalized hyperpigmentation and is known to appear after bilateral adrenalectomy. We report a case of unusual transient hyperpigmentation that developed immediately after unilateral adrenalectomy for pheochromocytoma and spontaneously resolved without corticosteroid supplementation. Case Description: A 29-year-old woman was admitted to the hospital due to sudden-onset chest pain and headache. A 2.8-cm left adrenal mass with heterogeneous enhancement was incidentally found in chest computed tomography during the evaluation. Multiple old infarctions were observed in brain magnetic resonance imaging (MRI), and left ventricular thrombi were found by echocardiography. Biochemical evidence confirmed the diagnosis of pheochromocytoma, while serum ACTH and cortisol levels were within normal ranges. The patient underwent laparoscopic left adrenalectomy via a posterior retroperitoneal approach and recovered without immediate postoperative complications. On day 3 after surgery, a crescent-shaped café-au-lait skin pigmentation occurred on both the subcostal and the lumbar areas of the abdomen. Serial serum cortisol slightly decreased during the immediate postoperative period and recovered on day 3. Serum ACTH was elevated. Under close observation without corticosteroid supplementation, the pigmentation faded on day 8 after surgery. On day 15, the pigmentation clearly disappeared and serum ACTH decreased to within the normal range. A month later, ACTH and all adrenal hormones were within normal range. Conclusions: We hypothesized that skin pigmentation appeared due to an imbalance of the hypothalamic-pituitary-adrenal (HPA) axis after resection of one adrenal gland. Skin pigmentation may be the first and early manifestation of adrenal insufficiency in patients who undergo unilateral adrenalectomy due to a non-Cushing's tumor. Therefore, a careful physical examination may allow early detection of adrenal insufficiency and optimal treatment planning.

RESUMO

Purpose: B-cell lymphoma 2 (BCL2) has an antiapoptotic role, however, has resulted in it being a powerful favorable prognostic factor in breast cancer. Several studies revealed BCL2 is strongly associated with a lower rate of early recurrence after initial treatment in breast cancer patients, but study of a prolonged effect after 5 years is lacking. We investigated BCL2 as a prognostic factor in breast cancer in comparison to early and late recurrence. Methods: We retrieved data from 2,198 patients with primary breast cancer who underwent surgical treatment and adjuvant treatment at the breast cancer center between 2005 and 2015. Each molecular subtype was classified, and Ki-67 and BCL2 were also assessed by immunohistochemistry. BCL2 and the association between molecular subtypes were assessed in early and late recurrences, respectively. Five-year postrecurrence survival and BCL2 were also assessed. Results: The BCL2-positive group was associated with favorable clinicopathologic characteristics. The time to recurrence was significantly longer in the BCL2-positive group (P = 0.035). Late recurrence after 5 years was higher in the BCL2-positive group (P = 0.029). In multivariate survival analysis, tumor size and BCL2-positive expression were the only independent prognostic factors for late recurrence (P = 0.004). In the patients with recurrence, 5-year postrecurrence survival was significantly higher in the BCL2-positive group (P < 0.001). Conclusion: Our result showed that prognosis was better in BCL2-positive patients compared to BCL2-negative patients at late recurrence. We suggested that BCL2 expression could be used as a marker to help determine additional adjuvant therapy or extended hormone therapy in hormone-dependent breast cancer.

RESUMO

OBJECTIVE: This study examined (a) whether there are a subgroup of cancer patients experiencing the selected psycho-neurological symptoms as a cluster (depression, cognitive impairment, fatigue, sleep disturbance, and pain); (b) whether demographic and clinical characteristics and pro-inflammatory cytokines (IL-1α, IL-1ß, IL-4, IL-6, TNF-alpha) are associated with subgroup membership; and (c) whether the activity of indolamine-2.3 dioxygenase(IDO) is associated with pro-inflammatory cytokine activity and psycho-neurological symptom cluster experience. METHODS: This was a prospective cohort study where 149 hematologic patients were recruited from a university hospital and 65 healthy volunteers provided control data. Latent profile analyses were conducted to identify subgroups at two time points: the last day of chemotherapy and 1 week after chemotherapy completion. Influencing factors of subgroup membership were examined by logistic regression. RESULTS: A substantial number of patients (33%, 34% at each time point) experienced the selected psycho-neurological symptoms as a cluster. Older age and elevated IL-1α and IL-6 were associated with experiencing the psycho-neurological symptom cluster. IDO activity was higher in the patients experiencing psycho-neurological symptom cluster; and was positively associated with IL-6. Symptom severity, IL-1α, IL-6, and IDO activity were all significantly higher in cancer patients than in the healthy controls. The findings were preserved across time points. CONCLUSIONS: The activation of pro-inflammatory cytokines and their cross-talk with IDO may be a common biological mechanism, underlying a psycho-neurological symptom cluster experience. The novel approaches for symptom assessment and management can be developed by assessing multiple psycho-neurological symptoms as a cluster and by targeting their common biological pathway.

RESUMO

Objective: This narrative review aims to (1) identify neuropsychological tests for assessing cognitive function impairment in patients with cancer, specifically in the domains of attention and memory, (2) summarize the characteristics of these tests, including cognitive function domains, test content, readability, and psychometric quality, and (3) evaluate the feasibility of each test in cancer care. Methods: Data sources include published test manuals, documents from official web pages, and published journal articles. Results: Our study identified eight neuropsychological tests that are most frequently used to assess the attention and memory domains of objective cognitive function in patients with breast cancer. These tests include the California Verbal Learning Test, Hopkins Verbal Learning Test, Rey Auditory Verbal Learning Test, Rey-Osterrieth Complex Figure, CNS Vital Signs, Wechsler Adult Intelligence Scale, Wechsler Memory Scale, and Trail Making Test. They demonstrate acceptable evidence of psychometric quality and varying degrees of feasibility. Test feasibility is influenced by factors such as short testing time, brevity and comprehensiveness, clear cognitive domain distinctions, availability of normative data, minimal practice effects, ease of administration, and limited attention-span requirements. These attributes determine a test's feasibility for use in cancer care. Among the evaluated measures, the California Verbal Learning Test for memory, the Trail Making Test for attention, and the CNS Vital Signs for comprehensive assessment emerge as the most practical choices for cancer care. Conclusions: The assessment and management of cognitive function impairment are crucial for enhancing the quality of life in cancer survivors. Nurses should possess knowledge of assessment tools for early detection and the ongoing monitoring of this symptom's progression.
