ABSTRACT

BACKGROUND AND OBJECTIVES: Functional dissociative seizures (FDS) are very common in neurology clinics, they straddle both neurology and psychiatry. In India, scarce resources and guidelines are available for effectively conveying their diagnosis and management, which leads to a substantial gap in care. We aimed to provide an instructional module for FDS, tailored to clinicians, patients, and caregivers in Hindi, to enhance communication of diagnosis and facilitate suitable management strategies.

METHODS: The instructional module development process was based on clinical settings and expert opinions. A standard translation process was performed to ensure the linguistic and cultural equivalence. Validation was carried out by a panel of 15 validators, comprising 13 neurologists and two psychiatrists, to identify key psychoeducation components and their significance. They were provided a questionnaire consisting of five questions that were related to completeness, understandability, legibility, clarification, and usefulness of educational material for clinicians, patients, and caregivers. Items were rated using a 5-point Likert scale.

RESULTS: There was agreement on four items (Q1, Q3, Q4, and Q5), whereas approximately 85% of the validators agreed on the remaining one item (Q2). The instructional module demonstrated high content validity as indicated by both item level-content validity index (0.98) and scale-level content validity index (0.97), alongside content validity ratio and modified kappa statistics.

CONCLUSIONS: The developed Hindi instructional module for FDS serves as a valuable tool to enhance the communication of FDS diagnosis and dispel misconceptions. This offers a comprehensive resource for clinicians, patients, and caregivers in India, potentially bridging gap in FDS care.

ABSTRACT

BACKGROUND: Colorectal cancer (CRC) represents the second leading cause of cancer-related mortality worldwide, with a significant portion of patients presenting with metastatic disease at diagnosis. Resistance to initial anti-EGFR therapy, a key treatment for RAS wild-type metastatic CRC, remains a major challenge. This study aimed to assess the efficacy and safety of rechallenge with anti-EGFR therapy in patients with metastatic CRC who have progressed after prior treatments.

METHODS: A systematic search was conducted across PubMed, Web of Science, Cochrane, and Scopus. Studies were included if they were randomized controlled trials (RCTs) or observational studies involving patients with EGFR-mutated metastatic CRC who received anti-EGFR therapy as a rechallenge. Endpoints included objective response rate (ORR), disease control rate (DCR), and the incidence of adverse events. Statistical analyses were performed using the DerSimonian/Laird random effect model, with heterogeneity assessed via I² statistics. R, version 4.2.3, was used for statistical analyses.

RESULTS: Fourteen studies were included with 520 patients; 50.3% were male, and the median age was 63 years old. The median progression-free survival (mPFS) ranged between 2.4 and 4.9 months, while the median overall survival (mOS) ranged from 5 to 17.8 months. Our pooled analysis demonstrated an objective response rate (ORR) of 17.70% (95% CI, 8.58-26.82%) and a disease control rate (DCR) of 61.72% (95% CI, 53.32-70.11%), both with significant heterogeneity (I², 84% and 80%, respectively; p < 0.01). In the subgroup analysis, cetuximab showed an ORR of 18.31% (95% CI, 4.67-31.94%), and panitumumab an ORR of 10.9% (95% CI, 0.00-26.82%), while the combination of both resulted in an ORR of 29.24% (95% CI, 0.00-65.84%). For DCR, cetuximab resulted in 62.1% (95% CI, 49.32-74.87%), panitumumab in 63.05% (95% CI, 52.13-73.97%), and the combination in 60.34% (95% CI, 31.92-88.77%), all with significant heterogeneity. Adverse events included anemia (15.39%), diarrhea (4.20%), hypomagnesemia (6.40%), neutropenia (22.57%), and skin rash (13.22%).

CONCLUSIONS: Rechallenge with anti-EGFR therapy in metastatic CRC patients shows moderate efficacy with manageable safety profiles. These findings highlight the need for careful patient selection and monitoring to optimize outcomes. Further studies are warranted to refine strategies for maximizing the therapeutic benefits of anti-EGFR rechallenge.

ABSTRACT

CONTEXT: Single-atom catalytic systems constitute an intriguing research topic due to their inherently different chemical behavior as compared to classic heterogeneous catalysts. In this study, cluster systems representing single late transition metal atoms adsorbed on anatase were constructed starting from previously generated periodic models and subjected to a density functional theory (DFT) benchmark study. The ability of different density functional approximations representing all rungs of the Jacob’s Ladder classification to accurately describe bond lengths and adsorption energies was assessed for these clusters with the aim of revealing the functional that allows to retain the structural characteristics of the initial periodic system, while also delivering reliable energetics. In this regard, our results indicate that optimisation of the clusters with the meta-GGA functionals TPSS or RevTPSS provides the lowest mean unsigned error and root-mean-square deviations with respect to the periodic models. Moreover, these functionals and, to a slightly lesser degree, PW91 were also found to provide adsorption energies that are statistically the least deviating from the CCSD(T) reference data. More complex hybrid functionals appear to be performing less well.

METHODS: Cluster geometries were determined at the Kohn-Sham DFT level using the LANL2DZ basis set for the transition metals and the Pople 6-31G(d) basis set for O and H. The density functional approximations considered were SVWN, PBE, BP86, BLYP, PW91, TPSS, RevTPSS, M06L, M11L, B3LYP, PBE0, M06, M06-2X, MN15, ωB97X-D, CAM-B3LYP, M11, and MN12-SX. Reference adsorption energies of the metals on the support cluster were obtained at the CCSD(T)/LANL2TZ (transition metals)/6-311 + + G(d,p)//RevTPSS/LANLD2DZ (transition metals)/6-31G*. Besides the above-mentioned functionals, energy calculations using the double-hybrid functionals, DSDPBEP86, PBE0-DH, and B2PLYP, were also performed. All adsorption energy calculations were carried out on the RevTPSS geometries.

ABSTRACT

BACKGROUND: Air pollution, a significant global health concern, notably impacts human well-being. Children, owing to their distinctive physiology and behavior, are particularly susceptible to its adverse effects. This prospective study examines air quality variations and respiratory risks in children residing in critically polluted areas (CPA) compared to relatively non-polluted areas (NPA), utilizing a prospective design to understand the impacts of air pollution on children’s respiratory health, including measures like relative risk (RR) and attributable risk (AR).

METHODS: This prospective study tracked 739 students of 5th- 7th grade residing in CPA and NPA for one year, and measured the ambient and indoor air quality levels in both these areas. Throughout the study, based on the observed respiratory symptoms new episodes of upper and lower respiratory tract illnesses were recorded for each child on a weekly basis. Incidence rate, RR and AR for both the illnesses were compared. Statistical analysis was performed with SPSS 26.0.

RESULTS: The study observes higher concentration for particulate matter and gaseous pollutants at CPA in comparison to NPA. Children living in CPA exhibited a notably greater weekly occurrence of both upper and lower respiratory tract illnesses compared to those in NPA, with RR of 1.26 (95% CI: 1.16-1.37) and 1.74 (95% CI: 1.34-2.27), respectively. The AR associated with air pollution for upper and lower respiratory tract illnesses among CPA students was found to be 20.7% and 42.7%, respectively.

CONCLUSION: This research underscores the pressing need to address air pollution in critically polluted areas and its profound effects on children’s respiratory health. Public health interventions, such as reducing emissions from industries and creating green spaces, should be prioritized. Furthermore, early respiratory health screening in schools within polluted areas could aid in the timely diagnosis and management of respiratory issues in children.

ABSTRACT

BACKGROUND: Hepatocellular carcinoma (HCC) is the most common primary liver cancer worldwide. Multiple observational studies demonstrated a negative association between the use of antithrombotic agents and the risk of HCC. However, the precise causal relationship between these factors remains uncertain. Therefore, our study used a two-sample Mendelian randomization (MR) analysis to assess the causal link between these two factors.

METHOD: The summary statistics of single nucleotide polymorphisms (SNPs) associated with the use of antithrombotic agents were acquired from a genome-wide association study (GWAS) performed on individuals of European descent. A two-sample MR analysis was performed using the inverse variance weighting (IVW), the weighted median estimate, the MR-Egger regression, and the weighted-mode estimate. Sensitivity analysis of the primary findings was performed using MR-PRESSO, MR-Egger regression, Cochran’s Q test, and Leave-one-out analysis.

RESULTS: Ten SNPs associated with the use of antithrombotic agents were selected as instrumental variables. The MR analysis performed using the four methods mentioned above revealed a negative causal association between the use of antithrombotic agents and HCC. Univariate MR estimates based on the inverse variance weighting (IVW) method suggested a negative causal association between the use of antithrombotic agents and HCC [odds ratio (OR) 0.444, 95% confidence interval (CI) 0.279 to 0.707, P = 0.001]. The other methods also produced similar results. No heterogeneity and horizontal pleiotropy were found.

CONCLUSION: Our findings suggested an inverse causal association of antithrombotic agents with the risk of HCC.

ABSTRACT

BACKGROUND: There is a gap in evidence about medical outcomes in oldest-old patients (aged 85 and older) with vertebral fractures (VFs). The aim of this study was to evaluate the impact of patient and fracture characteristics on “short-term” hospital outcomes.

METHODS: All patients aged ≥ 85 presenting an acute or subsequent VF at our single level I spine center between 2019 and 2021 requiring hospital treatment were included. The data collection was conducted retrospectively. The primary parameters of interest were length of stay (LOS) and in-hospital mortality. Further outcome parameters were the occurrence of general (non-operative) complications and Intensive Care Unit (ICU) admission. For statistical analysis, linear and binary logistic regression modeling were performed.

RESULTS: A total of 153 patients with an average age of 88.5 (range 85 to 99) met the inclusion criteria. Our patients were mostly female (68.6%) and moderately comorbid according to a Charlson Comorbidity Index (CCI) of 2.9. 58.8% had diagnosed osteoporosis. Fracture morphologies represented as “Osteoporotic Fracture” (OF) classification types were of central importance for undergoing operative treatment (OP) (p < 0.001), necessity for intensive care (p = 0.023), LOS (p = 0.014), and mortality (p = 0.018). 38.6% had OP. We recorded a complication rate of 59.5%, which highly influenced (p < 0.001) both primary outcome parameters. Overall, patients stayed 14.6 days with a mortality of 11.1%.

CONCLUSION: VFs are a severe event in oldest-old patients with a crucial risk of poor medical outcomes during hospitalization. The fracture morphologies are of central importance. However, little is known about the hospital stay of oldest-old inpatients with VFs. Considering an aging population, further investigations would be recommended.

ABSTRACT

PURPOSE: To examine health-related quality of life (HRQoL) and supportive care needs among young adult (YA) cancer survivors up to 3 years post-diagnosis.

METHODS: A national cohort of individuals diagnosed at 18-39 years with breast, cervical, ovarian, or testicular cancer, lymphoma or brain tumor was approached with surveys at 1.5 (n = 1010, response rate 67%) and 3 (n = 722) years post-diagnosis. HRQoL was measured using the EORTC QLQ-C30. Scores were dichotomized using cut-off scores to predict supportive care needs in the Supportive Care Needs Survey-Long Form 59 (SCNS-LF59). Swedish cancer quality registers provided clinical data. Factors predicting need of support at 1.5 and 3 years post-diagnosis were identified using logistic regression.

RESULTS: HRQoL improvements over time were trivial to small. At both time points, a majority of respondents rated HRQoL levels indicating supportive care needs. At 1.5 years post-diagnosis, the risk of having support needs was lower among survivors with testicular cancer (compared to lymphoma) or university-level education, and higher among those on treatment (predominantly endocrine therapy). At 3 years post-diagnosis, when controlling for previous HRQoL scores, most correlations persisted, and poor self-rated household economy and chronic health conditions were additionally associated with supportive care needs.

CONCLUSION: A majority of YAs diagnosed with cancer rate HRQoL at levels indicating support needs up to 3 years post-diagnosis. Testicular cancer survivors are at lower risk of having support needs. Concurrent health conditions and poor finances are linked to lower HRQoL. More efforts are needed to provide adequate, age-appropriate support to YA cancer survivors.

ABSTRACT

BACKGROUND: Laboratory-based biomarkers accurately presenting systemic lupus erythematosus (SLE) disease activity may have a practical value in clinical routine. As shown in many other conditions, complete blood count (CBC)-derived biomarkers may also play a role in SLE.

OBJECTIVES: We aimed to study for the first time the pan-immune-inflammation value (PIV, monocytes x platelets x neutrophils/lymphocytes) and the more established systemic immune-inflammation index (SII, neutrophils x platelets /lymphocytes) in SLE patients and correlate it with serological and clinical findings including disease outcomes.

METHODS: In this retrospective multicentric investigation, we reviewed the clinical records of 148 SLE who had an available CBC at baseline. The latter served for the determination of the neutrophil-to-lymphocyte ratio (NLR), SII, and the PIV. Control groups were studied as well. Univariable as well as multivariable statistics were employed.

RESULTS: The values for baseline systemic immune-inflammation biomarkers (SIIB) studied were significantly (p < 0.0001) higher than those observed in healthy controls but comparable to those obtained from patients with other inflammatory conditions. Multivariable analysis revealed that ANA titer > 1:640 remained the only significant (p < 0.0001) baseline predictor of SLE flare (odds ratio: 7.6, 95% CI 3.1 to 18.8). Improvement of SLE following treatment was associated with the absence of lymphopenia as well as ANA > 1:640 (p = 0.041). The SLEDAI-2K significantly correlated with NLR, SII, CRP, lymphocytes, and monocytes only on univariable testing.

CONCLUSIONS: Compared to healthy controls the CBC-based SIIB investigated are significantly increased in SLE patients. However, SIIB do not appear to be useful in managing SLE clinically. Nevertheless, we confirm that higher ANA titers can predict flares of SLE.

ABSTRACT

BACKGROUND: Education in end-of-life care (EoLC) is essential for improving the knowledge, attitudes and behaviours of intensive care nurses.

AIM: This study aimed to evaluate the effect of online awareness education, based on the End-of-Life Nursing Education Consortium, on the knowledge levels, attitudes and behaviours of intensive care nurses.

STUDY DESIGN: This single-centre randomized controlled study. This study was performed in a tertiary intensive care unit in a university-affiliated hospital. Seventy-six intensive care nurses were selected and equally randomized. In the education, the group was given an EoLC awareness education programme on an online platform as 40-60-min sessions once a week for 4 weeks. The descriptive Information Form, EoLC Knowledge Test and the Nurses’ Attitudes and Behaviours towards the EoLC Scale were used. In the study, intensive care nurses’ knowledge, attitude and behaviour levels towards EoLC were evaluated before and after 4 weeks (±3 days) following the education.

RESULTS: When the mean post-education scores of the nurses in the education group were compared with the control group, it was found that their mean scores on the EoLC Knowledge Test (p = .001, Cohen’s d = 1.354, 95% CI = 3.240-6.549), the attitude sub-dimension (p = .001, Cohen’s d = 1.520, 95% CI = 4.510-7.858), the behaviour sub-dimension (p = .001, Cohen’s d = 1.425, 95% CI = 3.206-6.214) and the total attitude and behaviour (p = .001, Cohen’s d = 1.927, 95% CI = 8.408-13.643) were statistically significantly higher than those of the control group.

CONCLUSION: This study showed that EoLC awareness education positively affected nurses’ knowledge, attitudes and behaviours. Accordingly, planning EoLC awareness education online at regular intervals may be recommended for intensive care nurses.

RELEVANCE TO CLINICAL PRACTICE: Intensive care nurses may be given online EoLC awareness education to positively affect their knowledge, attitudes and behaviours about EoLC. Online EoLC education can be effective in terms of reaching a large number of nurses, time and cost.

ABSTRACT

OBJECTIVE: Several approaches can be used in the surgical treatment of vestibular schwannoma (VS), and the best approach remains uncertain in the literature. This systematic review and meta-analysis aim to compare the translabyrinthine approach (TLA) with the retrosigmoid approach (RSA) for VS in terms of postoperative complications.

DATA SOURCES: PubMed, Web of Science, Embase, and Cochrane.

REVIEW METHODS: The primary outcome was cerebrospinal fluid (CSF) leak; secondary outcomes were facial nerve dysfunction (FND), length of stay (LOS), and meningitis. Statistical analysis was performed using RStudio 2024.04.1 + 748. Heterogeneity was assessed with I² statistics. We performed sensitivity analysis with subgroup analysis and meta-regression. Risk of bias was assessed using ROBINS-I.

RESULTS: Out of 1140 potential articles, 21 met the inclusion criteria. Among the 4572 patients, 2687 and 1885 patients in the TLA and RSA groups, respectively. No significant differences were found in CSF leak (odds ratio [OR] 1.03; 95% confidence interval [CI] 0.81,1.32; P = .794) or meningitis (OR 1.05; 95% CI 0.45, 2.43; P = .73). Meta-regression showed no association with CSF leak and the number of cases per center or publication year. The TLA is associated with a shorter LOS (MD -1.20; 95% CI -1.39, -1.01; P < .01) and a higher chance of having and HB 4 or lower compared to patients who underwent RSA (OR 0.30; 95% CI 0.10, 0.89; P = .03).

CONCLUSION: There was no difference in the odds of CSF leak or meningitis between the groups. In addition, the TLA has a shorter LOS and a higher chance of a better facial nerve outcome compared to the RSA.
