Treatment of glioblastoma with re-purposed renin-angiotensin system modulators: Results of a phase I clinical trial

J Clin Neurosci. 2021 Dec 4;95:48-54. doi: 10.1016/j.jocn.2021.11.023. Online ahead of print.

ABSTRACT

Glioblastoma is the most common and most aggressive primary brain cancer in adults. Standard treatment of glioblastoma consisting of maximal safe resection, adjuvant radiotherapy and chemotherapy with temozolomide, results in an overall median survival of 14.6 months. The aggressive nature of glioblastoma has been attributed to the presence of glioblastoma stem cells which express components of the renin-angiotensin system (RAS). This phase I clinical trial investigated the tolerability and efficacy of a treatment targeting the RAS and its converging pathways in patients with glioblastoma. Patients who had relapsed following standard treatment of glioblastoma who met the trial criteria were commenced on dose-escalated oral RAS modulators (propranolol, aliskiren, cilazapril, celecoxib, curcumin with piperine, aspirin, and metformin). Of the 17 patients who were enrolled, ten completed full dose-escalation of the treatment. The overall median survival was 19.9 (95% CI:14.1-25.7) months. Serial FET-PET/CTs showed a reduction in both tumor volume and uptake in one patient, an increase in tumor uptake in nine patients with decreased (n = 1), unchanged (n = 1) and increased (n = 7) tumor volume, in the ten patients who had completed full dose-escalation of the treatment. Two patients experienced mild side effects and all patients had preservation of quality of life and performance status during the treatment. There is a trend towards increased survival by 5.3 months although it was not statistically significant. These encouraging results warrant further clinical trials on this potential novel, well-tolerated and cost-effective therapeutic option for patients with glioblastoma.

Prognostic factors influencing survival following re-resection for isocitrate dehydrogenase (IDH) -wildtype glioblastoma multiforme – Data from a national neuro-oncology registry

J Clin Neurosci. 2021 Dec 17;95:142-150. doi: 10.1016/j.jocn.2021.12.011. Online ahead of print.

ABSTRACT

The role of surgical resection in recurrent Glioblastoma Multiforme (GBM) remains unclear. We aimed to investigate survival outcomes and associated prognostic factors in patients undergoing surgical re-resection for recurrent IDH-wildtype GBM in a national neuro-oncology center. We evaluated all patients who underwent re-resection for recurrent GBM following adjuvant treatment between 2015 and 2018. 32 patients were eligible for inclusion. 19 (59%) were male,median age at re-resection was 53. Median time from initial surgery to re-resection was 13.5 months. Median overall survival (OS) was 28.6 months from initial surgery and 9.5 months from re-resection. MGMT methylation was significantly associated with improved OS from initial surgery, 40 months versus 19.1 months, (p = 0.004), and from re-resection, 9.47 months versus 6.93 months, (p = 0.028). A late re-resection was associated with improved OS compared to an early re-resection, 44.1 months versus 15.7 months, (p = 0.002). There was a trend for improved outcomes in younger patients, median OS from initial surgery 44.1 months for <53 years compared to 21.7 months for patients ≥53, (p = 0.099). Higher Karnofsky Performance Status (KPS) at re-resection was associated with improved median OS, 9.5 months versus 4.1 months for KPS ≥70 and <70 respectively, (p = 0.013). Furthermore, there was a trend for improved OS with greater extent of re-resection, however this did not reach statistical significance, possibly due to small sample size. Re-resection for recurrent GBM was associated with improved OS in those with good performance status and could be considered in carefully selected cases.

How Parkinson’s patients in the USA perceive deep brain stimulation in the 21st century: Results of a nationwide survey

J Clin Neurosci. 2021 Dec 3;95:20-26. doi: 10.1016/j.jocn.2021.11.017. Online ahead of print.

ABSTRACT

Research on attitudes regarding the use and timing of deep brain stimulation (DBS) has been mostly qualitative to this date. In this study, we aim to examine attitudes and perceptions about the use and timing of DBS in patients with Parkinson’s disease (PD) who have not had DBS. We designed an online survey comprising Likert-type, multiple choice, and rank-order questions and distributed it to PD patients. We recruited participants via flyers, the Michael J. Fox Foundation Trial Finder, and the Parkinson Alliance website. We analyzed considerations for choosing or rejecting DBS and when participants would consider such a decision to be premature. Data were analyzed using descriptive and inferential statistics, including a multinomial logistic regression model. Among the 285 participants who reported not having undergone DBS, the most frequent concerns were related to the efficacy of DBS and not having exhausted medication alternatives. DBS was viewed as less convenient, effective, and safe when PD symptoms were still manageable by medication. Our regression model suggests that having fewer concerns over technical problems was a positive predictor of preferring early DBS, while concerns over DBS interfering with friendships and relationships was a negative predictor. Our results suggest that patients with PD who have not undergone DBS have a wide variety of attitudes regarding DBS and its timing. Given the increasing number of therapeutic options for PD, future work should compare perceptions and preferences regarding different PD treatment modalities to provide the best counseling for patients regarding their therapeutic options.

Effect of diabetes mellitus on pregnancy and birth outcomes in Wolaita Zone, Southern Ethiopia: A retrospective cohort study

Diabetes Metab Syndr. 2021 Dec 11;16(1):102364. doi: 10.1016/j.dsx.2021.102364. Online ahead of print.

ABSTRACT

BACKGROUND AND AIMS: Presence of diabetes mellitus (DM) during pregnancy is important cause of maternal and fetal complications. Studies that address the effect of DM on pregnancy and birth outcome are scarce in Ethiopia. The aim of this study was to determine the effect of DM on maternal and birth outcomes in Wolaita Zone, Southern Ethiopia.

METHODS: A retrospective cohort study was done to compare maternal and birth outcomes of mothers with DM and non-DM who received maternity service in three hospitals and four health centers in Southern Ethiopia. A total of 136 exposed (with DM) and 272 unexposed (non-DM) mothers were included in the study. Data were extracted from medical records of mothers by experienced and trained data collectors. Means were compared for continuous variables. Logistic regression analysis model was used to check the effect of DM on pregnancy and birth outcome. Risk Ratio was calculated and p value less than 0.05 was considered statistically significant.

RESULTS: Pregnancy of diabetic mothers was significantly complicated by pre-eclampsia when compared with non-diabetic mothers, (RR = 1.8: 95% CI; 1.2-2.7). The risk of macrosomia was higher for neonates of diabetic mothers than non-diabetic mothers, (RR = 1.9: 95% CI; 1.3-2.7). From multivariate analysis, mothers with DM were 2.9 times more likely to be delivered by caesarean section than non-diabetic mothers (RR = 2.9: 95%CI; 1.3-6.2) and the risk of pre-term delivery was 2.5 times higher among mothers with DM, (RR = 2.5: 95% CI; 1.1-6.2).

CONCLUSIONS: Diabetes mellitus among pregnant mothers is associated with increased risk of pre-term delivery, macrosomia and maternal complications of pre-eclampsia and caesarian delivery. Early detection and management of DM should be one of the key activities to improve maternal and child mortality and morbidity.

Diabetes Metab Syndr. 2021 Dec 13;16(1):102369. doi: 10.1016/j.dsx.2021.102369. Online ahead of print.

ABSTRACT

BACKGROUND AND AIMS: Classification of wound severity is important in medical care decisions specially in diabetic patients. The Wagner Scale provides a structure to determine the severity of a wound by examining its depth and extent. The adequate reliability of this instrument, like other instruments for measuring health status, is important. So, the aim of this review is to report evidence on the reliability of the Wagner scale.

METHOD: A comprehensive search was performed in databases. Observational studies that assessed the reliability of the Wagner scale, with statistical measures, were included. Methodological quality of studies was evaluated with the COSMIN checklist. Finally, we report the reliability measurements, narratively.

RESULTS: We assessed 7 studies. In all studies 1873 subjects participated. Methodological quality was good only in one study. In two studies used of weighted kappa (Inter Observer Reliability) that reliability was in median level in both studies. The relation between Wagner score and amputation were report in two studies that measured by X2trend and regression analysis. In four measurements, reported the correlation between Wagner with ulcer healing by X2trend, Log Rank, Kaplan-Meier, and inter quartile range.

CONCLUSION: It can be confirmed that the reliability of the Wagner scale is appropriate and this tool is recommended to evaluate the severity of the wounds specially in diabetic patients. It should also be noted that the user of the scale must be trained. In future studies, it is recommended to use appropriate methodology and complete reports for the reliability of Wagner scale.

A Review of Incident Prediction, Resource Allocation, and Dispatch Models for Emergency Management

Accid Anal Prev. 2021 Dec 17;165:106501. doi: 10.1016/j.aap.2021.106501. Online ahead of print.

ABSTRACT

In the last fifty years, researchers have developed statistical, data-driven, analytical, and algorithmic approaches for designing and improving emergency response management (ERM) systems. The problem has been noted as inherently difficult and constitutes spatio-temporal decision making under uncertainty, which has been addressed in the literature with varying assumptions and approaches. This survey provides a detailed review of these approaches, focusing on the key challenges and issues regarding four sub-processes: (a) incident prediction, (b) incident detection, (c) resource allocation, and (c) computer-aided dispatch for emergency response. We highlight the strengths and weaknesses of prior work in this domain and explore the similarities and differences between different modeling paradigms. We conclude by illustrating open challenges and opportunities for future research in this complex domain.

Immunohistochemical comparison of p63 and p40 in head and neck Spindle Cell Carcinoma

Pathol Res Pract. 2021 Dec 7;229:153733. doi: 10.1016/j.prp.2021.153733. Online ahead of print.

ABSTRACT

BACKGROUND: Spindle Cell Carcinoma (SpCC) is a rare type of squamous cell carcinoma (SCC) with prominent malignant spindle cell component. This unique biphasic feature on histopathological examination makes its diagnosis problematic. Detection of p63 antigens in SpCC can be helpful however its expression in variousb proliferating soft tissue lesions demands for better marker.

METHODS: In this study, histopathologically diagnosed SpCC of head and neck region were considered as cases, and 22 soft tissue sarcomas, reactive lesions and spindle cell lesions of the body were taken as controls. Immunohistochemistry (IHC) was done using Anti-p63 and p40 clone and the results were compared. CK was done for negative cases to prove their epithelial origin. P. value < 0.05 considered statistically significant.

RESULTS: Among 22 cases of SpCC, 19 cases showed positive immunoreactivity to p63, and 18 cases for p40. IHC of controls showed no immunoreactivity in any of the sarcomas, reactive lesions or spindle cell lesions. The sensitivity of p63 is 86% while that of p40 is 82%. Specificity of both the markers was 100% CONCLUSION: Though p63 is a slightly (4%) more sensitive marker than p40, percentage of cell positivity for p40 is higher compared to p63. Both of these markers are 100% specific for SpCC.

The effect of Huashibaidu formula on the blood oxygen saturation status of severe COVID-19: A retrospective cohort study

Phytomedicine. 2021 Dec 3;95:153868. doi: 10.1016/j.phymed.2021.153868. Online ahead of print.

ABSTRACT

BACKGROUND: Huashibaidu Formula (HSBD) for the COVID-19 treatment has been supported by the China’s Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia. However, it is not clear whether HSBD can improve blood oxygen saturation and when it should be used with conventional therapies.

PURPOSE: To access the effect of HSBD combined with conventional treatment on blood oxygen saturation of COVID-19 patients.

METHODS: A single-center retrospective cohort study was conducted to collect the confirmed severe COVID-19 patients’ information, treated by the National Traditional Chinese Medicine Medical Team at the Jinyintan hospital between January 24 and March 31, 2020. According to whether HSBD was used during hospitalization, participants were separated into the conventional treatment group and the HSBD group (HSBD and conventional treatment). The primary observation indicators included the time for relieving blood oxygen saturation and the improvement ratio of blood oxygen saturation in each group.

RESULTS: Of 111 patients with severe COVID-19, 53.2% (59/111) received HSBD, and 46.8% (52/111) only received conventional treatment, respectively. No statistically significant difference was found in image, clinical symptoms, and past medical history between the two groups (p > 0.05). Notably, the median time for relieving blood oxygen saturation in the conventional treatment group was 11 days (IQR, 8-14.25), while that in the HSBD group was only 6 days (IQR, 3.25-10.75), which was significantly shortened by 4.09 days (95%CI, 2.07-6.13; p= 0.0001), compared with the conventional treatment group. After repeated measurement design analysis, the main effect within times (p< 0.001) and the main effect were significantly different under the oxygen saturation dimension between two groups (p= 0.004). However, time and group interaction were observed no significant difference (p= 0.094). After 14 days of treatment, the improvement ratio of the HSBD group over the conventional treatment group was 1.20 (95%CI, 0.89-1.61).

CONCLUSION: For severe COVID-19 patients, the HSBD has a tendency to shorten the time for relieving blood oxygen saturation. After taking a course of HSBD, the effect can be more obvious.

nurses’ knowledge, skills and personal attributes for providing competent health education practice, and its influencing factors: A cross-sectional study

Nurse Educ Pract. 2021 Dec 15;58:103277. doi: 10.1016/j.nepr.2021.103277. Online ahead of print.

ABSTRACT

AIM: To explore nurses’ knowledge, skills and personal attributes for competent health education practice and their association with potential influencing factors.

BACKGROUND: Clinical nurses are expected to perform effective health education interventions, but they do not feel competent. The self-assessment of the health education competence and its conditional factors is paramount for professional development.

DESIGN: A cross-sectional study.

METHODS: A total of 458 clinical nurses from two health specialized centers in Spain participated in this study. Data were collected using the Nurse Health Education Competence Instrument and a second self-report questionnaire from January to February 2019. Descriptive statistics, t-test, analysis of variance, Pearson’s and Spearman’s correlation and multiple linear regression were used to analyse the data. The STROBE guideline was used RESULTS: The mean scores of the knowledge (70.10 ± 15.11), skills (92.14 ± 15.18) and personal attributes scales (32.32 ± 5.89) were found to be low to moderate. The main influencing factors for the health education implementation were lack of education and training (71.4%), lack of time (67.5%) and high workload (67.3%). Nurses with higher educational level and perceived self-efficacy for competently providing health education, more extensive professional experience and previous training in health education rated higher in knowledge, skills and personal attributes. Age and years of experience were negatively correlated with knowledge scores, but positively with the rest of domains of the competence and self-efficacy. The regression models for the overall health education competence’s domains were significant (p < 0.001) with R2 values ranging from 28.0% to 49.3%. Self-efficacy, previous health education training and working in intensive care units were found to be significant in all cognitive, psychomotor and attitudinal scales.

CONCLUSION: Clinical nurses reported on some skills and personal attributes for health education practice, but they seem to lack health education knowledge necessary for a competent practice. This study suggested that effective education and training and supportive organizational cultures are key to enhance nurses’ health education competence. Identifying nurses’ educational needs on the main domains of the competence and its intrinsic/extrinsic influential factors may assist in both planning and organizing tailored training strategies and in promoting appropriate environments to support a high-quality health education practice TWEETABLE ABSTRACT: Nurses’ knowledge, skills and attitudes about health education competence are low to moderate. Training and organizational support are key.

Relationship between immunometabolic status and cognitive performance among major depression disorder patients

Psychoneuroendocrinology. 2021 Dec 16;137:105631. doi: 10.1016/j.psyneuen.2021.105631. Online ahead of print.

ABSTRACT

BACKGROUND: Alterations in cognitive performance have been described in patients with major depressive disorder (MDD). However, the specific risk factors of these changes are not yet known. This study aimed to explore whether inmunometabolic parameters are related to cognitive performance in MDD in comparison to healthy controls (HC) METHODS: Sample consisted of 84 MDD patients and 78 HC. Both groups were compared on the results of cognitive performance measured with the Cambridge Neuropsychological Test Automated Battery (CANTAB), the presence of metabolic syndrome (MetS) and an inflammatory/oxidative index calculated by a principal component analysis of peripheral biomarkers (tumor necrosis factor, C-reactive protein and 4-hydroxynonenal). A multiple linear regression was carried out, to study the relationship between inmunometabolic variables and the global cognitive performance, being the latter the dependent variable.

RESULTS: Significant differences were obtained in the inflammatory/oxidative index between both groups (F(1157)= 12.93; p < .001), also in cognitive performance (F(1157)= 56.75; p < .001). The inmunometabolic covariate regression model (i.e., condition (HC/MDD), sex, age and medication loading, MetS, inflammatory/oxidative index and the interaction between MetS and inflammatory/oxidative index) was statistically significant (F(7157)= 11.24; p < .01) and explained 31% of variance. The condition, being either MDD or HD, (B=-0.97; p < .001), age (B=-0.28; p < .001) and the interaction between inflammatory/oxidative index and MetS (B=-0.38; p = .02) were factors associated to cognitive performance.

LIMITATIONS: Sample size was relatively small. The cross-sectional design of the study limits the possibilities of analysis.

CONCLUSIONS: Our results provide evidence on the conjoint influence of metabolic and inflammatory dysregulation on cognitive dysfunction in MDD patients. In this way, our study opens a line of research in immunometabolic agents to deal with cognitive decline associated with MDD.
