Characterization and quantification of epilepsy patients with hospital episodes in Portugal: A multicenter retrospective study from Liga Portuguesa Contra a Epilepsia.

INTRODUCTION: Epilepsy affects around 50 million people worldwide and is associated with lower quality of life scores, an increased risk of premature death, and significant socio-economic implications. The lack of updated evidence on current epidemiology and patient characterization creates considerable uncertainty regarding the epilepsy burden in Portugal. The study aims to characterize and quantify the epilepsy patients who have been hospitalized, with medical or surgical procedures involved, and to analyze their associated comorbidities and mortality rates. METHODS: A multicenter retrospective study was conducted using hospital production data of epilepsy patients. The study included all patients diagnosed with epilepsy-related International Classification of Diseases-9/10 codes between 2015 and 2018 in 57 Portuguese National Health Service (NHS) hospitals (n = 57 institutions). Patient characterization and quantification were done for all patients with an epilepsy diagnosis, with specific analyses focusing on those whose primary diagnosis was epilepsy. Baseline, demographic, and clinical characteristics were analyzed using descriptive statistics. RESULTS: Between 2015 and 2018, a total of 80,494 hospital episodes (i.e., patient visit that generates hospitalization and procedures) were recorded, with 18 % to 19 % directly related to epilepsy. Among these epilepsy-related hospital episodes, 13.0 % led to short term hospitalizations (less than 24 h). Additionally, the average length of stay for all these epilepsy-related episodes was 8 days. A total of 49,481 patients were identified with epilepsy based on ICD-9/10 codes. The median age of patients was 64 years (min: 0; max: 104), with a distribution of 4.8 patients per 1,000 inhabitants. From the total of deaths (9,606) between 2015 and 2018, 14% were associated with patients whose primary diagnosis was epilepsy, with 545 of these being epilepsy-related deaths. Among patients with a primary diagnosis of epilepsy, the most common comorbidities were hypertension (24%) and psychiatric-related or similar comorbidities (15%), such as alcohol dependance, depressive and major depressive disorders, dementia and other convulsions. CONCLUSION: This study showed similar results to other European countries. However, due to methodological limitations, a prospective epidemiological study is needed to support this observation. Furthermore, the present study provides a comprehensive picture of hospitalized epilepsy patients in Portugal, their comorbidities, mortality, and hospital procedures.

Using natural language processing to facilitate the harmonisation of mental health questionnaires: a validation study using real-world data.

BACKGROUND: Pooling data from different sources will advance mental health research by providing larger sample sizes and allowing cross-study comparisons; however, the heterogeneity in how variables are measured across studies poses a challenge to this process. METHODS: This study explored the potential of using natural language processing (NLP) to harmonise different mental health questionnaires by matching individual questions based on their semantic content. Using the Sentence-BERT model, we calculated the semantic similarity (cosine index) between 741 pairs of questions from five questionnaires. Drawing on data from a representative UK sample of adults (N = 2,058), we calculated a Spearman rank correlation for each of the same pairs of items, and then estimated the correlation between the cosine values and Spearman coefficients. We also used network analysis to explore the model's ability to uncover structures within the data and metadata. RESULTS: We found a moderate overall correlation (r = .48, p < .001) between the two indices. In a holdout sample, the cosine scores predicted the real-world correlations with a small degree of error (MAE = 0.05, MedAE = 0.04, RMSE = 0.064) suggesting the utility of NLP in identifying similar items for cross-study data pooling. Our NLP model could detect more complex patterns in our data, however it required manual rules to decide which edges to include in the network. CONCLUSIONS: This research shows that it is possible to quantify the semantic similarity between pairs of questionnaire items from their meta-data, and these similarity indices correlate with how participants would answer the same two items. This highlights the potential of NLP to facilitate cross-study data pooling in mental health research. Nevertheless, researchers are cautioned to verify the psychometric equivalence of matched items.

Molecular sensitization patterns of common food-and respiratory allergens in the Hungarian population.

BACKGROUND: Recently developed Immunoglobulin-E (IgE) based molecular allergy diagnostics provide the ability of identifying allergenic components or ingredients at the molecular level (component-resolved-diagnosis, CRD). Compared to the classical IgE-based allergy diagnostics, molecular technology is providing more sensitive and specific IgE-sensitization patterns. Certain sensitization patterns are characteristic of large geographic regions. There are only few data available on the molecular IgE sensitization patterns in East-Central Europe. This study aims to present further data from this region. METHODS: Data of 3993 stored, anonymized molecular ImmunoCap IgE measurements (CRD), performed in Hungary between January-December 2019 from sera of 1288 subjects (mean age: 27 years ±18 years, male/female ratio 0.56) were analyzed retrospectively, in order to get a local distributional pattern of the sensitizing (IgE >0.35 KU/l) molecular allergens. RESULTS: The proportion of CRD positive cases was 24.3%. Amongst them, the most prevalent inhalative allergens were Amb a 1 (18%) Art v 1 (8%) in adults and Der p 2 (3%) and Der p 1 (3%) and Amb a 1 (4%) in subjects below 18 years of age. The same for food allergens were Gal d 2 (21%), Bos d 4 (17%), Bos d 5 (11%) in adults and Gal d 2 (38%), Gal d 1 (28%), Bos d 4 (21%), Bos d 5 (13%) and Bos d 8 (7%) in children. The ratio of mono-sensitivities among CRD-positive cases was 37.5%. CONCLUSION: Our results provide region-specific patterns of sensitization and molecular allergen spreading for Hungary. The relatively higher abundance of polysensitization's among allergic cases underlines the need for early diagnostic -and preventive measures in the future.

Access to surgical care in Ethiopia: a cross-sectional retrospective data review.

BACKGROUND: Access to emergency and essential surgical care is still unmet and accessibility is disproportionately inequitable in Ethiopia and other low-and middle-income countries. The aim of this study was to assess surgical care access in terms of capability, capacity, and timeliness of care in different levels of health care in Ethiopia. METHODS: A cross-sectional study with retrospective data review was conducted in 172 health facilities from December 30, 2020 to June 10, 2021. Descriptive statistics such as median with interquartile range and proportion were computed using STATA Version 15 statistical software. RESULTS: Within a 90-day interval of the study period, 69,717 major and minor surgeries, and 33,052 bellwether procedures were performed, and major surgeries accounted for 58% of the surgeries. About 1.6%, 23.56%, 25.34%, and 32.2% of both major and minor, and 3.1%, 12.8%, 27.6%, and 45.3% of bellwether procedures were performed in health center OR blocks, primary, general, and specialized hospitals, respectively. Private hospitals performed 17.33% of major and minor and 11.2% of bellwether procedures for the period. The average pre-admission waiting time for surgical patients in primary, general, and specialized hospitals was 9.68, 37.6, and 35.9 days, respectively, whereas, in private hospitals, the average pre-admission waiting time was 1.42 days. On average, surgical patients traveled 5 Hrs, 11 Hrs, 28.4 Hrs, and 21.3 Hrs to access surgical services in primary, general, specialized, and private hospitals, respectively. The surgical workforce to the population served ratio was 7.5, 1.15, and 1.31/100.000 population in primary, specialized and general hospitals, respectively. CONCLUSION: Most surgical procedures were performed in specialized hospitals, indicating that there is a burden in these health facilities. The pre-admission waiting time for surgical patients was long in higher-level public hospitals. Surgical patients traveled a long distance to access surgical service in higher level hospitals. The ratio of surgical workforce per 100,000 population served was low in all levels of public health facilities in general, and in higher level hospitals in particular. Efforts should therefore be made to strengthen all levels of the health system and improve surgical care access in terms of capacity, capability, and timeliness in the country.

Retrospectively Collected EQ-5D-5L Data as Valid Proxies for Imputing Missing Information in Longitudinal Studies.

OBJECTIVES: Studies face challenges with missing 5-level EQ-5D (EQ-5D-5L) data, often because of the need for longitudinal EQ-5D-5L data collection. There is a dearth of validated methodologies for dealing with missing EQ-5D-5L data in the literature. This study, for the first time, examined the possibility of using retrospectively collected EQ-5D-5L data as proxies for the missing data. METHODS: Participants who had prospectively completed a 3rd month postdischarge EQ-5D-5L instrument (in-the-moment collection) were randomly interviewed to respond to a 2nd "retrospective collection" of their 3rd month EQ-5D-5L at 6th, 9th, or 12th month after hospital discharge. A longitudinal single imputation was also used to assess the relative performance of retrospective collection compared with the longitudinal single imputation. Concordances between the in-the-moment, retrospective, and imputed measures were assessed using intraclass correlation coefficients and weighted kappa statistics. RESULTS: Considerable agreement was observed on the basis of weighted kappa (range 0.72-0.95) between the mobility, self-care, and usual activities dimensions of EQ-5D-5L collected in-the-moment and retrospectively. Concordance based on intraclass correlation coefficients was good to excellent (range 0.79-0.81) for utility indices computed, and excellent (range 0.93-0.96) for quality-adjusted life-years computed using in-the-moment compared with retrospective EQ-5D-5L. The longitudinal single imputation did not perform as well as the retrospective collection method. CONCLUSIONS: This study demonstrates that retrospective collection of EQ-5D-5L has high concordance with "in-the-moment" EQ-5D-5L and could be a valid and attractive alternative for data imputation when longitudinally collected EQ-5D-5L data are missing. Future studies examining this method for other disease areas and populations are required to provide more generalizable evidence.

Acute and transitional care or rehabilitation? Retrospective analysis of discharge planning from a municipal hospital in Switzerland.

BACKGROUND: Due to rising health care costs, in 2012 Switzerland introduced SwissDRG, a reimbursement system for hospitals based on lump sum per case. To circumvent possible negative consequences like reduction in length of stay, acute and transitional care (ATC) was anchored into the law (Federal act on health insurance) in 2011. ATC as a discharge option is applicable to patients who physicians deem will not fulfill rehabilitation criteria, but are unable to return home and are in need of temporary professional nursing care. ATC is associated with higher out of pocket costs to the patient than rehabilitation. Since social service workers are responsible for organizing discharge for patients with ongoing care needs after hospitalization, the aim of this study was to investigate how social service workers manage patient discharge in light of the new discharge option ATC. METHODS: Data was collected from 423 medical records of inpatients from Zurich's municipal hospital, Triemli, discharged to ATC or rehabilitation, in 2016. We compared the two groups using inferential statistics and qualitatively analyzed written statements from social service workers. RESULTS: Our results showed that patients discharged to rehabilitation had a higher total number of discussions, but a shorter duration of discussions. Patients discharged to rehabilitation faced more delays, mainly due to unavailability of beds in rehabilitation centers. Conflicts concerning discharge arose mainly because of costs, discharge placement and too early discharge. CONCLUSIONS: Our findings demonstrate how important social service workers are in providing information to patients about different discharge options. The newness of SwissDRG and ATC is still likely to cause longer discussion times and, consequently, more workload for social service workers. Only a small fraction of patients disagreed with their place of discharge, mostly due to financial reasons.

Exploring Monitoring Systems Data for Driver Distraction and Drowsiness Research.

Driver inattention is a major contributor to road crashes. The emerging of new driver monitoring systems represents an opportunity for researchers to explore new data sources to understand driver inattention, even if the technology was not developed with this purpose in mind. This study is based on retrospective data obtained from two driver monitoring systems to study distraction and drowsiness risk factors. The data includes information about the trips performed by 330 drivers and corresponding distraction and drowsiness alerts emitted by the systems. The drivers' historical travel data allowed defining two groups with different mobility patterns (short-distance and long-distance drivers) through a cluster analysis. Then, the impacts of the driver's profile and trip characteristics (e.g., driving time, average speed, and breaking time and frequency) on inattention were analyzed using ordered probit models. The results show that long-distance drivers, typically associated with professionals, are less prone to distraction and drowsiness than short-distance drivers. The driving time increases the probability of inattention, while the breaking frequency is more important to mitigate inattention than the breaking time. Higher average speeds increase the inattention risk, being associated with road facilities featuring a monotonous driving environment.

Using human experience to identify drug repurposing opportunities: theory and practice.

Retrospective evidence drawn from real-world experience of a medicine's use outside its labelled indication is one of a number of techniques used in drug repurposing (DRP). Relying as it does on large numbers of real incidences of human experience, rather than individual case reports with limited statistical support, preclinical experiments with poor translatability or in silico associations, which are early-stage hypotheses, it represents the best validated form of DRP. Cancer is the most frequent of such DRP examples (e.g. aspirin in pancreatic cancer, hazard ratio = 0.25). This approach can be combined with pathway analysis to provide first-in-class treatments for complex diseases. Alternatively, it can be combined with prospective preclinical studies to uncover a validated mechanism for a new indication, after which a repurposed molecule is chemically optimized.

Assessing a composite end point for new tocolytics in clinical trials: Data from 4 US integrated delivery networks.

PURPOSE: A composite end point (CE) measuring neonatal benefit was created for use in tocolytic randomized controlled trials with rates assessed using data from one referral hospital. The goal of this study was to assess wider generalizability of the CE, using data from multiple integrated delivery networks, creating a cohort of linked mother-neonate pairs to understand neonatal outcomes in a broad population. METHODS: Retrospective data on births (2001-2012) were collected from 4 US integrated delivery networks in the COMparative effectiveness PAtient Safety and Surveillance (COMPASS) Research Network, and linked mother-neonate pairs were identified. The CE was analyzed for all in-hospital singleton neonates at ≥24 weeks of gestational age (GA) born to mothers aged ≤45 years at a referral hospital or hospital with >2000 annual births. RESULTS: The CE analyses included 56 485 eligible mother-neonate pairs; frequency of the CE decreased from 89% to 66% between GA weeks 24 and 29 and further decreased to <14% for infants born >34 weeks of GA. Composite end point rates were 20% to 30% lower at 24 to 30 weeks of GA in COMPASS compared with Medical University of South Carolina but were similar by 31 weeks. CONCLUSIONS: The COMPASS Network enabled evaluation of the CE across a large population demonstrating that the CE findings could be replicated beyond a single hospital and the potential for lower CE frequency. Based on this, an adaptive design was adopted for randomized controlled trials, specifically sample size reestimation to mitigate against the risk of lower outcome rates, highlighting the use of real-world data in drug development.

"Memory bias" for recall of experiences during initial weight loss is affected by subsequent weight loss outcome.

Research has suggested that memories of mood, emotions, and behaviors are not purely unbiased retrieval, but more similar to reconstructions based on current opinions, positive or negative experiences associated with the memory, and how a person believes they would have felt, thought, or acted. We investigated this memory bias in 66 adult participants with overweight/obesity who rated their mood, emotions, and behaviors during a 12-week, Internet-based behavioral weight loss program and later recalled these ratings at Month 3 (immediate post-test) and Month 12 (follow-up). At Month 3, participants recalled the intervention more positively than reported previously, p = .010, but reported remembering the intervention more negatively at the Month 12 follow-up, p = .004. Memory bias was associated with initial weight loss and regain, ps < .05, such that participants who lost more weight at Month 3 remembered their mood, emotions, and behaviors during intervention more positively, and those who regained more weight at Month 12, more negatively. Future research should investigate whether this bias is associated with willingness to re-engage with intervention.

Improving tablet coating robustness by selecting critical process parameters from retrospective data.

CONTEXT: Although tablet coating processes are widely used in the pharmaceutical industry, they often lack adequate robustness. Up-scaling can be challenging as minor changes in parameters can lead to varying quality results. OBJECTIVE: To select critical process parameters (CPP) using retrospective data of a commercial product and to establish a design of experiments (DoE) that would improve the robustness of the coating process. MATERIALS AND METHODS: A retrospective analysis of data from 36 commercial batches. Batches were selected based on the quality results generated during batch release, some of which revealed quality deviations concerning the appearance of the coated tablets. The product is already marketed and belongs to the portfolio of a multinational pharmaceutical company. RESULTS: The Statgraphics 5.1 software was used for data processing to determine critical process parameters in order to propose new working ranges. DISCUSSION AND CONCLUSIONS: This study confirms that it is possible to determine the critical process parameters and create design spaces based on retrospective data of commercial batches. This type of analysis is thus converted into a tool to optimize the robustness of existing processes. Our results show that a design space can be established with minimum investment in experiments, since current commercial batch data are processed statistically.

Psychosocial work factors and first depressive episode: retrospective results from the French national SIP survey.

OBJECTIVES: The objective was to explore the associations between psychosocial work factors and first depressive episode. Additional objectives included the study of the frequency and duration of exposure, and the evaluation of the induction period between exposures and outcome and of the reversibility of the effects. METHODS: The study was based on a sample of 13,648 men and women from the 2006 national representative French SIP survey. Retrospective evaluation was performed for depressive episode for the whole life history, for psychological demands, skill discretion, social support, tension with the public, reward and work-life imbalance for each job, and within each job before and after each major change, and for time-varying covariates. The outcome was the first depressive episode. Statistical analysis was performed using weighted discrete time logistic regression model. RESULTS: High psychological demands and low social support were risk factors for first depressive episode for both genders. The risk increased with the frequency of exposure to these factors. Associations were found with the frequency of exposure to tension with the public among women and to work-life imbalance among men. The risk increased with the duration of exposure to psychological demands and low social support for both genders, however, these associations become non-significant when recent exposure was taken into account. Past exposure older than 2 years was not associated with the outcome. CONCLUSION: Associations between psychosocial work factors and first depressive episode were observed, including dose-response associations. However, after removal of the exposure, the risk may be reduced after 2 years.

PROSPECTIVE VERSUS RETROSPECTIVE APPROACHES TO THE STUDY OF INTERGENERATIONAL SOCIAL MOBILITY.

Most intergenerational social mobility studies are based upon retrospective data, in which samples of individuals report socioeconomic information about their parents, an approach that provides representative data for offspring but not the parental generation. When available, prospective data on intergenerational mobility, which are based on a sample of respondents who report on their progeny, have conceptual and practical advantages. Prospective data are especially useful for studying social mobility across more than two generations and for developing joint models of social mobility and demographic processes. Because prospective data remain relatively scarce, we propose a method that corrects retrospective mobility data for the unrepresentativeness of the parental generation, and thus permits them to be used for models of social mobility and demographic processes. We illustrate this method using both simulated data and data from the Panel Study of Income Dynamics. In our examples, this method removes more than 95% of the bias in the retrospective data.

FSGT capsule inhibits IL-1ß-induced inflammation in chondrocytes and ameliorates osteoarthritis by upregulating LncRNA PACER and downregulating COX2/PGE2.

OBJECTIVE: To explore the efficacy and potential mechanism of Fengshi Gutong capsule (FSGTC) in osteoarthritis (OA) inflammation. METHODS: The impact of FSGTC on laboratory indicators of OA patients was explored using data mining technology and association rule analysis. Then, the OA cell model was constructed by inducing chondrocytes (CHs) with interleukin-1ß (IL-1ß). In the presence of FSGTC intervention, the regulatory mechanism of PACER/COX2/PGE2 in OA-CH viability and inflammatory responses was evaluated. RESULTS: Retrospective data mining showed that FSGTC effectively reduced inflammation indexes (ESR, HCRP) of OA patients. Cell experiments showed that LncRNA PACER (PACER) silencing inhibited the proliferation activity of OA-CHs, increased the level of COX2 protein, elevated the levels of PGE2, TNF-α, and IL-1ß, and decreased the levels of IL-4 and IL-10 (p < .01). On the contrary, FSGTC-containing serum reversed the effect of PACER silencing on OA-CHs (p < .01). After the addition of COX2 pathway inhibitor, the proliferation activity of OA-CHs was enhanced; the levels of PGE2, TNF-α, and IL-1ß were decreased while the levels of IL-4 and IL-10 were increased (p < .01). CONCLUSION: FSGTC inhibits IL-1ß-induced inflammation in CHs and ameliorates OA by upregulating PACER and downregulating COX2/PGE2.

Trends and Patterns in Emergency Department Visits: A Comprehensive Analysis of Adult Data From the National Center for Health Statistics (NCHS) Database.

Background Emergency department (ED) visits among adults have increased in recent years, with the United States reporting 140 million ED visits in 2021, equating to an overall rate of 43 visits per 100 people. This trend underscores challenges in accessing primary care and addressing underlying health conditions. Understanding the trends and patterns in ED utilization is essential for informing healthcare policy and practice. Objective This study aims to comprehensively analyze trends and patterns in ED visits among adults using data from the National Center for Health Statistics (NCHS) database. Methods We conducted a retrospective analysis of ED visit data from 1999 to 2019, focusing on adults aged 18 and over. The prevalence rates of ED visits were examined across demographic, socioeconomic, and geographic groups using datasets retrieved from the NCHS database. Statistical analysis included one-way ANOVA and chi-square tests to assess variations in ED visit rates. Results This study's findings revealed a consistent increase in overall ED visits among adults, from 17.2 ± 0.3% in 1999 to 21.7 ± 0.3% in 2019. Disparities in ED utilization were evident across demographic and socioeconomic groups. Females had slightly higher visit rates, and significant racial disparities were noted, with American Indian or Alaska Native and Black or African American individuals showing the highest visit rates. Age-specific variations were observed, with young adults (18-24 years) and older adults (65 years and above) exhibiting higher visit rates. Socioeconomic status and health insurance coverage emerged as significant determinants, highlighting disparities in healthcare access. Conclusion This study provides valuable insights into the trends and patterns of ED visits among adults, emphasizing the need for targeted interventions to address healthcare disparities and improve access to primary care services.

Real-World Safety and Effectiveness of a Bevacizumab Biosimilar (ABP 215) in Metastatic Colorectal Cancer Patients in Canada.

BACKGROUND: ABP 215 is a biosimilar to the reference product, bevacizumab, and was one of the first biosimilars approved by Health Canada for the first-line treatment of metastatic colorectal cancer (mCRC). This study aimed to address gaps in real-world evidence (RWE) including patient characteristics, treatment safety (primary objective), and effectiveness (secondary objective) for first-line ABP 215 therapy in Canadian patients with mCRC. MATERIALS AND METHODS: Retrospective data were collected in 2 waves, at least 1 year (Wave 1) or 2 years (Wave 2) after commercial availability of ABP 215 at each participating site. RESULTS: A total of 75 patients from Wave 1 and 164 patients from Wave 2 treated with a minimum of 1 cycle of ABP 215 were included. At least one safety event of interest (EOI) was recorded for 34.7% of Wave 1 and 42.7% of Wave 2 patients. The median progression free survival (PFS) for Wave 1 and 2 patients were 9.47 (95% confidence interval [CI]: 6.71, 11.90) and 21.38 (95% CI: 15.82, not estimable) months, respectively. Median overall survival was not estimable for Wave 1 and was 26.45 months for Wave 2. CONCLUSION: The safety and effectiveness of ABP 215 observed in this real-world study were comparable to clinical trial findings and to other RWE with longer PFS in the current study.

Method validation of an inductively coupled plasma mass spectrometry (ICP-MS) assay for the analysis of magnesium, copper and zinc in red blood cells.

Background: Laboratory measurements of trace elements such as magnesium (Mg), copper (Cu), and zinc (Zn) in red blood cells (RBCs) are essential for assessing nutritional status and diagnosing metal toxicity. The purpose of this study was to develop and validate an ICP-MS method for quantifying these elements in RBCs. Methods: Packed RBCs were aliquoted and diluted in an alkaline diluent solution containing internal standards, 0.1 % Triton X-100, 0.1 % EDTA, and 1 % ammonium hydroxide. The resulting diluted specimen was analyzed using inductively coupled plasma mass spectrometry (ICP-MS) to quantitatively determine the levels of Mg, Cu, and Zn. The method underwent validation for accuracy, precision, method comparison, linearity, analytical sensitivity, and carryover. Additionally, retrospective data were analyzed, and non-parametric reference intervals were calculated. Results: Accuracy and linearity fell within the expected range of ≤±15 % for all analytes. Within-run, between-run, and total imprecision were ≤15 % coefficient of variation. All other validation experiments met the established acceptance criteria. Retrospective data analysis was conducted on patient samples using the method. The application of Tukey's HSD test for multiple comparisons revealed statistically significant mean differences (p < 0.05) in Mg, Cu, and Zn concentrations between all pairwise groups of age and sex, except for the mean Cu concentration in adult males versus females and the mean Mg concentrations in adult versus minor males. Conclusions: The presented method was successfully validated and met the criteria for clinical use. Retrospective data analysis of patient results demonstrated the method's suitability for assessing nutritional deficiency and toxicity.

Effect of Sequence of Radiotherapy Combined With Immunotherapy on the Incidence of Pneumonitis in Patients With Lung Cancer: A Systematic Review and Network Meta-Analysis.

BACKGROUND: With the widespread application of immune checkpoint inhibitor (ICI) combined with radiotherapy (RT) for the treatment of lung cancer, increasing attention has been paid to treatment-related pneumonitis. The effect of the treatment sequence on the incidence of pneumonitis remains unclear. METHODS: We searched databases including PubMed, Embase, and ClinicalTrials.gov, meeting abstracts, and reference lists of relevant review articles for literature published on radio- and immunotherapy in lung cancer. Stata software (version 16.0) was used for meta-analysis. Data on the incidence of any grade and ≥ grade 3 pneumonitis was pooled using the random effects model. Bayesian network meta-analysis was used for arm-based pairwise comparisons. Subgroup analyses were performed to identify the potential influencing factors. RESULTS: Thirty-eight studies met our inclusion criteria. The network meta-analysis showed no significant difference between the incidence of pneumonitis in concurrent ICI with RT (concurrent arm) and RT followed by ICI (RT-first arm) (odds ratio [OR]: 0.71, 95% confidence interval [CI]: 0.10-4.81). In the meta-analysis of single group rates, RT following ICI (ICI-first arm) exhibited higher incidence of any grade pneumonitis compared with concurrent- and RT-first arms, with 0.321 (95% CI: 0.260-0.386) for programmed cell death protein 1 (PD-1) inhibitors from clinical trials, and 0.480 (95% CI: 0.363-0.598) for PD-1 inhibitors from real-world retrospective data, respectively. CONCLUSION: No significant difference in the incidence of any grade and grade ≥ 3 pneumonitis was found between RT-first and concurrent arms. The ICI-first arm exhibited a higher incidence of pneumonitis, which needs to be further confirmed by follow-up studies.

Rise in Autism Spectrum Disorder Diagnoses: A Comparative Analysis of Pre-pandemic and Pandemic Periods.

Introduction  This study analyzes the rise in autism spectrum disorder (ASD) diagnoses by comparing pre-pandemic (2017-2019) and pandemic period (2021-2023) data from two private pediatric practices with different populations in New York. The year 2020 was out of the analysis to focus on the impact after the shutdowns on ASD, and there were disruptions in clinic operations during that year. Clinic I primarily served an African-American ethnic population, while Clinic II primarily served an Asian population. Methods A retrospective analysis was conducted using de-identified patient numbers from the electronic medical records (EMR) of two private clinics. Only the numbers of new patients diagnosed each year were included from January 1, 2017, to December 31, 2019 (pre-pandemic), and January 1, 2021, to December 31, 2023 (pandemic). Sixteen ASD International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) codes were included in this analysis. Descriptive and inferential statistics were used to find important patterns and determine statistical significance. Results The study included 537 patients, 182 from Clinic I and 355 from Clinic II. Clinic I demonstrated a significant increase in ASD diagnoses, from 63 (pre-pandemic) to 119 (pandemic) (χ2=17.23; p=0.000033). Clinic II demonstrated a significant increase in ASD diagnoses, from 149 (pre-pandemic) to 206 (pandemic) (χ2=9.15; p=0.00248). Conclusion The significant increase in ASD diagnoses in two private pediatric practices with different populations indicates a notable association with the shutdown periods and the pandemic. Factors such as disrupted routines, changes in access to healthcare services, and increased parental awareness may have contributed to this rise. Further longitudinal studies are needed to understand the long-term impacts of the pandemic on ASD diagnoses and care.

[Androgen deprivation as initial and backbone therapy for prostate carcinoma cancer : A retrospective data analysis from urological practices in Germany]. / Androgendeprivation als Initial- und Basistherapie beim Prostatakarzinom : Eine retrospektive Datenanalyse aus urologischen Praxen in Deutschland.

BACKGROUND: The aim of this study was to determine the proportion of patients with prostate cancer (PCa) who remained on primary androgen deprivation therapy (ADT) after starting treatment for castration-resistant prostate cancer (CRPC) and to describe their treatment patterns. MATERIALS AND METHODS: The study comprises a retrospective analysis of 609,308 patients in urological practices in Germany from 2011 to 2020 based on anonymized secondary data from the UROscience webserver. PCa patients were eligible for inclusion if they received ADT after a 6-month prescription-free pre-index period. RESULTS: A total of 3,112 patients (mean age 75.5 [±8.0] years) were included. Most patients received gonadotropin-releasing hormone (GnRH) agonists (72.3%), followed by antiandrogens (24.9%). The median duration of ADT treatment was 25.9 months. The estimated probabilities of continuing ADT 3, 6, and 8 years after starting treatment were 40.7%, 20.1%, and 12.7%, respectively. Interruption across all ADTs occurred in 42.7% of patients, switching of primary ADT in 52.2% and discontinuation in 82.2% of patients. After starting ADT, 14.6% of patients received treatment for CRPC, of whom 76.4% continued primary ADT. The median duration of CRPC treatment was 11.0 months. The estimated probabilities of developing CRPC 3, 6, and 8 years after starting ADT were 11.1%, 20.1%, and 25.9%, respectively. CONCLUSION: This study has shown that a relevant proportion of patients discontinued primary ADT after starting treatment for CRPC, although guidelines recommend continuing ADT if the disease progresses.
