State Cannabis Legalization and Psychosis-Related Health Care Utilization

JAMA Netw Open. 2023 Jan 3;6(1):e2252689. doi: 10.1001/jamanetworkopen.2022.52689.

ABSTRACT

IMPORTANCE: Psychosis is a hypothesized consequence of cannabis use. Legalization of cannabis could therefore be associated with an increase in rates of health care utilization for psychosis.

OBJECTIVE: To evaluate the association of state medical and recreational cannabis laws and commercialization with rates of psychosis-related health care utilization.

DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort design using state-level panel fixed effects to model within-state changes in monthly rates of psychosis-related health care claims as a function of state cannabis policy level, adjusting for time-varying state-level characteristics and state, year, and month fixed effects. Commercial and Medicare Advantage claims data for beneficiaries aged 16 years and older in all 50 US states and the District of Columbia, 2003 to 2017 were used. Data were analyzed from April 2021 to October 2022.

EXPOSURE: State cannabis legalization policies were measured for each state and month based on law type (medical or recreational) and degree of commercialization (presence or absence of retail outlets).

MAIN OUTCOMES AND MEASURES: Outcomes were rates of psychosis-related diagnoses and prescribed antipsychotics.

RESULTS: This study included 63 680 589 beneficiaries followed for 2 015 189 706 person-months. Women accounted for 51.8% of follow-up time with the majority of person-months recorded for those aged 65 years and older (77.3%) and among White beneficiaries (64.6%). Results from fully-adjusted models showed that, compared with no legalization policy, states with legalization policies experienced no statistically significant increase in rates of psychosis-related diagnoses (medical, no retail outlets: rate ratio [RR], 1.13; 95% CI, 0.97-1.36; medical, retail outlets: RR, 1.24; 95% CI, 0.96-1.61; recreational, no retail outlets: RR, 1.38; 95% CI, 0.93-2.04; recreational, retail outlets: RR, 1.39; 95% CI, 0.98-1.97) or prescribed antipsychotics (medical, no retail outlets RR, 1.00; 95% CI, 0.88-1.13; medical, retail outlets: RR, 1.01; 95% CI, 0.87-1.19; recreational, no retail outlets: RR, 1.13; 95% CI, 0.84-1.51; recreational, retail outlets: RR, 1.14; 95% CI, 0.89-1.45). In exploratory secondary analyses, rates of psychosis-related diagnoses increased significantly among men, people aged 55 to 64 years, and Asian beneficiaries in states with recreational policies compared with no policy.

CONCLUSIONS AND RELEVANCE: In this retrospective cohort study of commercial and Medicare Advantage claims data, state medical and recreational cannabis policies were not associated with a statistically significant increase in rates of psychosis-related health outcomes. As states continue to introduce new cannabis policies, continued evaluation of psychosis as a potential consequence of state cannabis legalization may be informative.

Lipid Alteration Signature in the Blood Plasma of Individuals With Schizophrenia, Depression, and Bipolar Disorder

JAMA Psychiatry. 2023 Jan 25. doi: 10.1001/jamapsychiatry.2022.4350. Online ahead of print.

ABSTRACT

IMPORTANCE: No clinically applicable diagnostic test exists for severe mental disorders. Lipids harbor potential as disease markers.

OBJECTIVE: To define a reproducible profile of lipid alterations in the blood plasma of patients with schizophrenia (SCZ) independent of demographic and environmental variables and to investigate its specificity in association with other psychiatric disorders, ie, major depressive disorder (MDD) and bipolar disorder (BPD).

DESIGN, SETTING, AND PARTICIPANTS: This was a multicohort case-control diagnostic analysis involving plasma samples from psychiatric patients and control individuals collected between July 17, 2009, and May 18, 2018. Study participants were recruited as consecutive and volunteer samples at multiple inpatient and outpatient mental health hospitals in Western Europe (Germany and Austria [DE-AT]), China (CN), and Russia (RU). Individuals with DSM-IV or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnoses of SCZ, MDD, BPD, or a first psychotic episode, as well as age- and sex-matched healthy controls without a mental health-related diagnosis were included in the study. Samples and data were analyzed from January 2018 to September 2020.

MAIN OUTCOMES AND MEASURES: Plasma lipidome composition was assessed using liquid chromatography coupled with untargeted mass spectrometry.

RESULTS: Blood lipid levels were assessed in 980 individuals (mean [SD] age, 36 [13] years; 510 male individuals [52%]) diagnosed with SCZ, BPD, MDD, or those with a first psychotic episode and in 572 controls (mean [SD] age, 34 [13] years; 323 male individuals [56%]). A total of 77 lipids were found to be significantly altered between those with SCZ (n = 436) and controls (n = 478) in all 3 sample cohorts. Alterations were consistent between cohorts (CN and RU: [Pearson correlation] r = 0.75; DE-AT and CN: r = 0.78; DE-AT and RU: r = 0.82; P < 10-38). A lipid-based predictive model separated patients with SCZ from controls with high diagnostic ability (area under the receiver operating characteristic curve = 0.86-0.95). Lipidome alterations in BPD and MDD, assessed in 184 and 256 individuals, respectively, were found to be similar to those of SCZ (BPD: r = 0.89; MDD: r = 0.92; P < 10-79). Assessment of detected alterations in individuals with a first psychotic episode, as well as patients with SCZ not receiving medication, demonstrated only limited association with medication restricted to particular lipids.

CONCLUSIONS AND RELEVANCE: In this study, SCZ was accompanied by a reproducible profile of plasma lipidome alterations, not associated with symptom severity, medication, and demographic and environmental variables, and largely shared with BPD and MDD. This lipid alteration signature may represent a trait marker of severe psychiatric disorders, indicating its potential to be transformed into a clinically applicable testing procedure.

Lactobacilli Probiotics Modulate Antibacterial Response Gene Transcription of Dendritic Cells Challenged with LPS

Probiotics Antimicrob Proteins. 2023 Jan 25. doi: 10.1007/s12602-023-10043-z. Online ahead of print.

ABSTRACT

Probiotics are beneficial bacteria that may modulate the immune response by altering the maturation and function of antigen-presenting cells, such as dendritic cells. This study aimed to evaluate the antibacterial gene expression of dendritic cells challenged with LPS and probiotics. Immature dendritic cells were obtained from human CD14+ monocytes and challenged with E. coli LPS and probiotics Lacticaseibacillus rhamnosus (LR-32) and Lactobacillus acidophilus (LA-5) at a ratio DC:bacteria of 1:10. The analysis of gene expression was performed by RT-qPCR using the Kit RT2 human antibacterial response. In the supernatant, the cytokines secretion was determined by ELISA. Tukey post-ANOVA with p at 5% was used for statistical analysis. LPS showed the higher upregulation of 29 genes compared with the groups where probiotics were added to LPS, including genes related to an inflammatory response like BIRC3, CASP1, CCL5, CXCL1, IL12B, IL18, MYD88, NLRP3, RIPK1, and TIRAP. Similarly, LPS increased the transcription of genes enrolled with apoptosis such as CARD6, CASP1, IRF5, MAP2K1, MAP2K4, MAPK1, MYD88, NLRP3, RIPK2, TNF, TNFRSF1A, and XIAP when compared to probiotics groups (p < 0.05). Although probiotics decrease several genes upregulated by LPS, the transcription of encoded cytokines IL12A, IL12B, IL1B, IL6, CXCL8, and TNF genes was maintained upregulated by probiotics, except for IL18, which was downregulated by LA-5. LA-5 led to a higher transcription of IL1B, IL6, and CXCL-8 which was followed by the secretion of these proteins by ELISA. The results suggest that probiotics attenuate the transcription of inflammatory and immune response genes caused by LPS.

Fostering firm performance through the lens of environmental leadership and knowledge learning: a mediated moderation model

Environ Sci Pollut Res Int. 2023 Jan 25. doi: 10.1007/s11356-023-25415-9. Online ahead of print.

ABSTRACT

In the current era of business, environmental sustainability has emerged as an issue of critical relevance. The main purpose of this study is to examine the relationship between environmental leadership and environmental learning and its impact on the organization’s performance. This research contributes to the existing body of knowledge by identifying the primary characteristics that help companies enhance their performance. Using a convenience sample approach, data was obtained from 417 respondents working in the construction industry. For direct and indirect hypothesis testing, we used the Statistical Package for the Social Sciences (SPSS) and structural equation modelling (SEM). According to the study’s findings, environmental leadership (EL) and environmental knowledge learning (EKL) significantly influence environmental passion (EP), green corporate social responsibility (CSR), and company performance. The link between EL, EKL, and firm performance (FP) is mediated by EP. The study’s results indicate that green CSR significantly moderates the relationship between EP and firm performance. The study findings benefit business managers, policymakers, and government institutions.

Genes Genomics. 2023 Jan 25. doi: 10.1007/s13258-022-01361-7. Online ahead of print.

ABSTRACT

BACKGROUND: Microsoft Excel has substantial functionalities for data management and analyses, and has been the most popular software in this field. However, in spite of Excel’s user-friendly interface and functionality for data management, it provides very few functions for in-depth statistical analyses, which has limited its wider application for this purpose.

OBJECTIVE: Here, we introduce Rex, an Excel add-in software implementing the powerful analytical and graphical functions of R within Excel.

METHODS: Rex was implemented using three types of programming software: R, JavaScript, and Microsoft VB.Net.

RESULTS: Rex provides a graphical user interface (GUI) through Excel, and statistical analysis can be conducted by pointing and clicking the menu without programming R. Rex covers a wide range of analyses from basic statistics to advanced analysis, including structural equation modeling, complex sampling design, and machine learning models, making it possible for researchers not skilled in using a command-line interface to conduct in-depth statistical analyses. Most Rex modules are available in a free version for non-commercial use, and it can be used for educational and public purposes.

CONCLUSION: In this article, we introduce the framework and features of Rex with illustrative examples of its implementation.

The Use of Area-Level Socioeconomic Indices in Evaluating Cancer Care Delivery: A Scoping Review

Ann Surg Oncol. 2023 Jan 25. doi: 10.1245/s10434-023-13099-x. Online ahead of print.

ABSTRACT

BACKGROUND: Multiple composite indices of small-area socioeconomic characteristics have been used to examine how neighborhood characteristics influence cancer care, but there is little consensus regarding how to use them. This scoping review aimed to summarize the use of these indices in cancer literature and their association with outcomes.

METHODS: A search was conducted to identify studies from 2015 to 2021 that investigated cancer incidence, disease stage at diagnosis, and mortality using area-based indices of deprivation as an independent variable. Studies were screened and assessed for eligibility. Data were extracted regarding the geospatial and statistical use of these indices.

RESULTS: All the inclusion criteria were met by 45 studies. The area level of analysis was at the census tract level in 19 studies (42.3%), the county level in 15 studies (33.3%), the block group level in 6 studies (13.3%), and the ZIP code level in 5 studies (11.1%). Altogether, 18 unique indices were used, with 4 indices used most frequently. Of the studies that used their indices ordinally, 3 defined high and low deprivation dichotomously, 10 used tertiles, 13 used quartiles, and 15 used quintiles. Of the 45 studies, 34 (76%) showed a significant association between area deprivation and cancer-related outcomes.

CONCLUSIONS: Neighborhood deprivation indices are most commonly used at the census tract level and ordinally as quintiles. Despite variance in methods, there is a strong indication that deprived areas are at adverse odds with cancer-related outcomes. Further study investigating deprivation in the context of cancer can inform drivers of inequity and identify potential targets for care delivery and policy interventions.

Impact of a Health Education Intervention on the Incidence of Influenza-Like Illnesses (ILI) During Hajj via Smartphone Application

J Immigr Minor Health. 2023 Jan 25. doi: 10.1007/s10903-022-01443-4. Online ahead of print.

ABSTRACT

This study was aimed at demonstrating the impact of a health education intervention on reducing the incidence of influenza-like illnesses symptoms among Malaysian Hajj pilgrims. This study utilizes a quasi-experimental study in the evaluation of the impact of the intervention. Participants were recruited during Hajj orientation courses organized by private Hajj companies. Participants from two companies were assigned to an intervention group and control group, respectively. The intervention group received a smartphone-based health education intervention guided by the Health Belief Model (HBM), while the control group received a regular Hajj guide intervention smartphone application before departure to Hajj. Data on the incidence of influenza-like illnesses (ILI) were collected from participants from two Hajj companies before and after returning from Hajj. Data analysis was conducted using SPSS with descriptive analysis, and analytical tests were conducted at 5% significance level. A total of 102 pilgrims completed the study in both intervention and control groups. The incidence of ILI and Non-ILI symptoms were statistically significant when the intervention and control groups (p = 0.049) were compared. In conclusion, health education has an impact on reducing the incidence of ILI and non-ILI among Hajj pilgrims.

Evaluating the efficacy of post-operative chemotherapy after curative resection of stage IV gastric cancer with synchronous oligo metastasis: a multicenter retrospective study

Gastric Cancer. 2023 Jan 25. doi: 10.1007/s10120-023-01363-8. Online ahead of print.

ABSTRACT

BACKGROUND: Surgical resection of oligo-metastasis in gastric cancer (GC) is weakly recommended for patients without other incurable factors in the Japanese GC Treatment Guidelines. While post-operative chemotherapy is the standard treatment in patients with stage II or III GC, its efficacy for resected stage IV GC is unclear. This study aimed to evaluate the efficacy of post-operative chemotherapy after curative resection of GC with oligo-metastasis.

METHODS: We retrospectively reviewed the medical records of patients with GC who were diagnosed with synchronous oligo-metastasis at 20 institutions in Japan between 2007 and 2012. The selection criteria were: adenocarcinoma, stage IV with oligo-metastasis at liver or lymph node without other distant metastasis, curative resection including synchronous oligo-metastasis, and no prior treatment of GC before surgery.

RESULTS: A total of 110 patients were collected. Of the 94 eligible patients, 84 underwent gastrectomy with surgical resection of oligo-metastasis (39 [41%] liver metastasis and 55, [59%] distant lymph node metastasis), followed by post-operative chemotherapy with S-1 (S1: n = 55), S1 plus cisplatin (CS: n = 22), or Others (n = 7). Moreover, 10 patients did not receive post-operative chemotherapy (Non-Cx). The median overall survival (OS) was 35.2 and 11.1 months in the post-operative chemotherapy and Non-Cx groups (hazard ratio, 3.56; 95% confidence interval, 1.74-7.30; p < 0.001), respectively. In multivariable analysis, Non-Cx and age over 70 years were identified as poor prognostic factors for OS (p < 0.05).

CONCLUSIONS: Curative resection followed by post-operative chemotherapy in patients with GC with synchronous oligo-metastasis showed favorable survival.

Incidence and risk factors of tuberculosis in patients following gastrectomy or endoscopic submucosal dissection: a cohort analysis of country-level data

Gastric Cancer. 2023 Jan 25. doi: 10.1007/s10120-023-01367-4. Online ahead of print.

ABSTRACT

BACKGROUND: Gastric cancer adversely affects nutrition and immunity, while increasing the risk of tuberculosis (TB). This study investigated the incidence and risk factors for TB in gastric cancer patients who had undergone gastrectomy or endoscopic submucosal dissection (ESD).

METHODS: This retrospective cohort study was conducted using Korean national insurance claims data. We defined three study groups (total gastrectomy, subtotal gastrectomy, and ESD) of patients diagnosed with gastric cancer plus a cancer-free control group. The latent TB infection (LTBI) screening status, TB incidence, and potential confounders in each cohort were analyzed, and the risk of TB was analyzed using a Cox proportional hazard model.

RESULTS: LTBI tests were performed in less than 1% of all patients, and the TB incidence rates were 473.8, 287.4, 199.4, 111.1 events/100,000 person-years in the total gastrectomy, subtotal gastrectomy, ESD, and control cohorts, respectively. Compared to the control cohort, the total gastrectomy cohort showed the highest hazard ratio (HR) for TB incidence (HR: 2.896, 95% CI: 2.559-2.337), while the ESD cohort showed a significantly increased risk (HR: 1.578, 95% CI: 1.957-1.980). Age, body mass index, and lack of exercise were risk factors in all cohorts. Comorbidities were also considered risk factors, depending on the cohort type.

CONCLUSIONS: Patients who underwent gastrectomy or ESD had an increased risk of TB, and this risk was correlated with the scope of gastrectomy. Considering the low rate of LTBI diagnostic tests and increased risk of TB in the study cohorts, more specific and practical guidelines for TB management are required for gastric cancer patients.

Marginal gaps and voids using two warm compaction techniques and different sealers: a micro-CT study

Clin Oral Investig. 2023 Jan 25. doi: 10.1007/s00784-023-04866-x. Online ahead of print.

ABSTRACT

OBJECTIVE: To assess the percentage of marginal gaps and voids in oval-shaped canals obturated by using two warm compaction techniques with a Bio-C sealer and AH Plus Jet.

MATERIALS AND METHODS: Forty canines with oval canals were scanned by microcomputed tomography (micro-CT), and root canal preparation was performed with an XP-endo Shaper system and irrigated with 5.25% sodium hypochlorite. Then, the specimens were paired into four groups (n=10) according to the root canal filling technique and endodontic sealer: Bio-C sealer and continuous wave of condensation, Bio-C sealer and Tagger’s hybrid, AH Plus Jet and continuous wave of condensation, and AH Plus Jet and Tagger’s hybrid. After root canal filling, a new scan was performed. The percentage of marginal gaps and voids was calculated with the ImageJ software, and the data were analyzed statistically using two-way ANOVA and Tukey tests, with a significance level of 5%.

RESULTS: The percentage of marginal gaps was significantly lower in the Bio-C sealer than in AH Plus Jet (p=0.021) regardless of the technique. However, no difference was found in the percentage of voids between root canal filling techniques and the endodontic sealer (p>0.05).

CONCLUSION: Both sealers and techniques demonstrated good quality of root canal filling. However, the use of the Bio-C sealer enhanced the filling ability by reducing marginal gaps, regardless of the root canal filling technique.

CLINICAL RELEVANCE: This study highlights the better performance of the Bio-C sealer in the quality of the root canal filling, reducing marginal gaps when compared to AH Plus Jet independent of the technique.
