OBJECTIVE
Rapid eye movement (REM)-dependent obstructive sleep apnea syndrome (OSAS) is a specific subtype of OSAS having some phenotypic characteristics like a preference for a younger age, female gender, and milder severity. Such favorable features could make it possible to consider an overall benign course for this phenotype. However, accumulating data introduced its association with several cardiometabolic and vascular disorders recently. The primary objective of this study was to address the disease from the inflammation perspective and evaluate the potential inflammatory status in this variant via two accessible blood parameters: platelet distribution width (PDW) and systemic immune-inflammation index (SII). The secondary aim was to investigate whether this status, together with other disease characteristics, demonstrates consistency under different definitions of REM-dependent OSAS published previously.
PATIENTS AND METHODS
The medical records of 35 patients with mild-to-moderate REM-dependent OSAS, 35 age- and sex-matched patients with REM-independent OSAS, and 25 non-OSA controls were retrospectively analyzed. Baseline features, polysomnographic characteristics, PDW, and SII were compared between the groups. Secondly, the analyses were repeated using different definitions of REM-dependent OSAS. Bivariate analyses were performed, and a multiple stepwise regression model was applied to adjust for body mass index (BMI) and cardiovascular risk (CVR) factors. RESULTS: Mean PDW and SII were increased in patients with REM-dependent OSAS as compared to non-OSA controls (p = .022 and .029). The significance remained stable after adjustment for BMI and CVRs and was consistent according to different definitions. The Comparison of patients with REM-independent OSAS and non-OSA controls, as well as the two different subtypes of OSAS, did not yield significance.
CONCLUSION
Based on the current findings, patients with REM-dependent OSAS appear to be susceptible to inflammation and should be carefully monitored for the negative consequences of that issue. To our knowledge, this study is the first to evaluate SII and PDW in REM-dependent OSAS.

BACKGROUND
As the most commonly used illicit substance, cannabis is gaining global acceptance through increasing legalization efforts. This shift intensifies the need for research to guide policymakers and healthcare providers in harm reduction and treatment strategies. Nonetheless, the relationship between psychopathological symptoms and cannabis use remains inadequately understood.
METHODS
A sample of regular cannabis consumers completed self-reported assessments for depression (Patient Health Questionnaire-9), anxiety (General Anxiety Disorder-7), Attention-Deficit/Hyperactivity Disorder (ADHD; Adult ADHD Self-Report Scale V1.1), and psychosis (Early Recognition Inventory based on IRAOS) as well as previous black-market cannabis use patterns. Cannabis Use Disorder Identification Test Revised (CUDIT-R) was used to identify cannabis use disorder (CUD). To understand psychopathological symptom load related to cannabis consumption as well as cannabis use motives, multiple regression models were performed to identify psychopathological variables predicting cannabis use frequency and quantity. Linear regression and correlation analyses were conducted, adjusting for relevant covariates (age, gender, education, alcohol, other substance use).
RESULTS
Three-hundred-sixty regular cannabis users interested in a study on regulated cannabis access in Basel, Switzerland were examined. In bivariate analysis, cannabis use frequency correlated with depressive ((358) = 0.16, = 0.003) and anxiety symptom load ((358) = 0.11, = 0.034). Cannabis quantity correlated with depressive ((358) = 0.15, = 0.005), ADHD ((358) = 0.14, = 0.008), and psychosis symptom load ((358) = 0.16, = 0.002). However, in the adjusted regression models only depressive and ADHD symptom loads were significantly associated with cannabis use frequency ( = 0.006 and = 0.034, respectively) and quantity ( = 0.037 and = 0.019, respectively). No significant correlations between cannabis consumption and anxiety or psychosis remained after adjustment.
CONCLUSION
ADHD and depressive symptoms correlate with increased cannabis use in a cohort of regular users, suggesting potential self-medication in nonclinical populations. With the rising availability of cannabis worldwide, these results highlight the necessity for longitudinal studies to disentangle the complex dynamics between cannabis consumption and mental health symptoms.

Nihon Ronen Igakkai Zasshi. Japanese... 2024To examine the relationship between decreased appetite and the cognitive function in elderly diabetic patients.
OBJECTIVE
To examine the relationship between decreased appetite and the cognitive function in elderly diabetic patients.
METHODS
The study subjects were outpatients with diabetes who were 60 years of age or older, and who were managed at Ise Red Cross Hospital. The cognitive function was assessed using a self-administered Dementia Checklist. The Japanese version of the Simplified Nutritional Appetite Questionnaire (SNAQ) was used to measure decreased appetite. A logistic regression analysis, in which the dependent variable was cognitive decline and the explanatory variables were appetite loss and adjustment variables, was used to calculate the odds ratio for cognitive decline according to the presence of appetite loss.
RESULTS
Four hundred eighty patients were included in the analysis. Seventeen percent of the patients had decreased appetite and 21% had a decreased cognitive function. The unadjusted and adjusted odds ratios of cognitive decline for those with decreased appetite were 2.78 (95% confidence interval (CI), 1.66-4.65; P<0.001) and 2.26 (95% CI, 1.16-4.37; P=0.015), respectively, based on the absence of decreased appetite.
CONCLUSION
Decreased appetite in elderly patients with diabetes was associated with a decreased cognitive function.

IMPORTANCE
Pediatric consensus guidelines recommend antibiotic administration within 1 hour for septic shock and within 3 hours for sepsis without shock. Limited studies exist identifying a specific time past which delays in antibiotic administration are associated with worse outcomes.
OBJECTIVE
To determine a time point for antibiotic administration that is associated with increased risk of mortality among pediatric patients with sepsis.
DESIGN, SETTING, AND PARTICIPANTS
This retrospective cohort study used data from 51 US children's hospitals in the Improving Pediatric Sepsis Outcomes collaborative. Participants included patients aged 29 days to less than 18 years with sepsis recognized within 1 hour of emergency department arrival, from January 1, 2017, through December 31, 2021. Piecewise regression was used to identify the inflection point for sepsis-attributable 3-day mortality, and logistic regression was used to evaluate odds of sepsis-attributable mortality after adjustment for potential confounders. Data analysis was performed from March 2022 to February 2024.
EXPOSURE
The number of minutes from emergency department arrival to antibiotic administration.
MAIN OUTCOMES AND MEASURES
The primary outcome was sepsis-attributable 3-day mortality. Sepsis-attributable 30-day mortality was a secondary outcome.
RESULTS
A total of 19 515 cases (median [IQR] age, 6 [2-12] years) were included. The median (IQR) time to antibiotic administration was 69 (47-116) minutes. The estimated time to antibiotic administration at which 3-day sepsis-attributable mortality increased was 330 minutes. Patients who received an antibiotic in less than 330 minutes (19 164 patients) had sepsis-attributable 3-day mortality of 0.5% (93 patients) and 30-day mortality of 0.9% (163 patients). Patients who received antibiotics at 330 minutes or later (351 patients) had 3-day sepsis-attributable mortality of 1.2% (4 patients), 30-day mortality of 2.0% (7 patients), and increased adjusted odds of mortality at both 3 days (odds ratio, 3.44; 95% CI, 1.20-9.93; P = .02) and 30 days (odds ratio, 3.63; 95% CI, 1.59-8.30; P = .002) compared with those who received antibiotics within 330 minutes.
CONCLUSIONS AND RELEVANCE
In this cohort of pediatric patients with sepsis, 3-day and 30-day sepsis-attributable mortality increased with delays in antibiotic administration 330 minutes or longer from emergency department arrival. These findings are consistent with the literature demonstrating increased pediatric sepsis mortality associated with antibiotic administration delay. To guide the balance of appropriate resource allocation with time for adequate diagnostic evaluation, further research is needed into whether there are subpopulations, such as those with shock or bacteremia, that may benefit from earlier antibiotics.

Women veterans are more likely than men veterans to receive medications that Department of Veterans Affairs clinical practice guidelines recommend against to treat posttraumatic stress disorder (PTSD). To understand this difference, we examined potential confounders in incident prescribing of guideline discordant medications (GDMs) in veterans with PTSD. Veterans receiving care for PTSD during 2020 were identified using Veterans Health Administration administrative data. PTSD diagnosis was established by the presence of at least 1 coded outpatient encounter or inpatient hospitalization during the calendar year 2020. Incident GDM prescribing was assessed during 2021, including benzodiazepines, antipsychotics, select anticonvulsants, and select antidepressants. Log-binomial regression was used to estimate the difference in risk for GDM initiation between men and women, adjusted for patient, prescriber, and facility-level covariates, and to identify key confounding variables. Of 704,699 veterans with PTSD, 16.9% of women and 10.1% of men initiated a GDM, an increased risk of 67% for women [relative risk (RR) = 1.67; 95% CI, 1.65-1.70]. After adjustment, the gender difference decreased to 1.22 (95% CI, 1.20-1.24) in a fully specified model. Three key confounding variables were identified: bipolar disorder (RR = 1.60; 95% CI, 1.57-1.63), age (<40 years: RR = 1.20 [1.18-1.22]; 40-54 years: RR = 1.13 [1.11-1.16]; ≥65 years: RR = 0.64 [0.62-0.65]), and count of distinct psychiatric medications prescribed in the prior year (RR = 1.14; 1.13-1.14). Women veterans with PTSD were 67% more likely to initiate a GDM, where more than half of this effect was explained by bipolar disorder, age, and prior psychiatric medication. After adjustment, women veterans remained at 22% greater risk for an incident GDM, suggesting that other factors remain unidentified and warrant further investigation.

European Journal of Cardio-thoracic... Jun 2024The causal association between immune cell traits and aortic aneurysm remains unknown.
OBJECTIVES
The causal association between immune cell traits and aortic aneurysm remains unknown.
METHODS
We performed a bidirectional two-sample Mendelian randomization analysis to explore the causality between 731 immune cell characteristics and the risk of abdominal aortic aneurysm and thoracic aortic aneurysms through publicly available genetic data, respectively. To examine heterogeneity and horizontal pleiotropy, Cochran's Q test and MR-Egger intercept were utilized. Additionally, multivariable Mendelian randomization analysis and meta-analysis were performed in further analysis.
RESULTS
We found that 20 immune phenotypes had a suggestive causality on abdominal aortic aneurysm, and 15 immune phenotypes had a suggestive causal effect on thoracic aortic aneurysm. After further false discovery rate adjustment (q value <0.1), CD20 on IgD+ CD38- B cell (q = 0.053) and CD127 on CD28+ CD4+ T cell (q = 0.096) were associated with an increased risk of abdominal aortic aneurysm, respectively, indicating a significant causality between them. After adjusting for smoking, there is still statistical significance between CD127 on CD28+ CD4+ T cell and abdominal aortic aneurysm. However, after adjusting for lipids, no statistical significance can be observed between CD127 on CD28+ CD4+ T cells and abdominal aortic aneurysm. Furthermore, there is still statistical significance between CD20 on IgD+ CD38- B cells and abdominal aortic aneurysm after adjusting for lipids and smoking, which was further identified by meta-analysis.
CONCLUSIONS
We found a causal association between immune cell traits and aortic aneurysm by genetic methods, thus providing new avenues for future mechanism studies.

BACKGROUND
Therapeutic drug monitoring (TDM) is strongly recommended for olanzapine due to its high pharmacokinetic variability. This study aimed to investigate the impact of various clinical factors on olanzapine plasma concentrations in patients with psychiatric disorders.
METHODS
The study used TDM data from the PsyMetab cohort, including 547 daily dose-normalized, steady-state, olanzapine plasma concentrations (C:D ratios) from 248 patients. Both intrinsic factors (eg, sex, age, body weight) and extrinsic factors (eg, smoking status, comedications, hospitalization) were examined. Univariate and multivariable, linear, mixed-effects models were employed, with a stepwise selection procedure based on Akaike information criterion to identify the relevant covariates.
RESULTS
In the multivariable model (based on 440 observations with a complete data set), several significant findings emerged. Olanzapine C:D ratios were significantly lower in smokers (β = -0.65, P < 0.001), valproate users (β = -0.53, P = 0.002), and inpatients (β = -0.20, P = 0.025). Furthermore, the C:D ratios decreased significantly as the time since the last dose increased (β = -0.040, P < 0.001). The male sex had a significant main effect on olanzapine C:D ratios (β = -2.80, P < 0.001), with significant interactions with age (β = 0.025, P < 0.001) and body weight (β = 0.017, P = 0.011). The selected covariates explained 30.3% of the variation in C:D ratios, with smoking status accounting for 7.7% and sex contributing 6.9%. The overall variation explained by both the fixed and random parts of the model was 67.4%. The model facilitated the prediction of olanzapine C:D ratios based on sex, age, and body weight.
CONCLUSIONS
The clinical factors examined in this study, including sex, age, body weight, smoking status, and valproate comedication, remarkably influence olanzapine C:D ratios. Considering these factors, in addition to TDM and the clinical situation, could be important for dose adjustment.

The global escalation of obesity has made it a worldwide health concern, notably as a leading risk factor for cardiovascular disease (CVD). Extensive evidence corroborates its association with a range of cardiac complications, including coronary artery disease, heart failure, and heightened vulnerability to sudden cardiac events. Additionally, obesity contributes to the emergence of other cardiovascular risk factors including dyslipidaemia, type 2 diabetes, hypertension, and sleep disorders, further amplifying the predisposition to CVD. To adequately address CVD in patients with obesity, it is crucial to first understand the pathophysiology underlying this link. We herein explore these intricate mechanisms, including adipose tissue dysfunction, chronic inflammation, immune system dysregulation, and alterations in the gut microbiome.Recent guidelines from the European Society of Cardiology underscore the pivotal role of diagnosing and treating obesity to prevent CVD. However, the intricate relationship between obesity and CVD poses significant challenges in clinical practice: the presence of obesity can impede accurate CVD diagnosis while optimizing the effectiveness of pharmacological treatments or cardiac procedures requires meticulous adjustment, and it is crucial that cardiologists acknowledge the implications of excessive weight while striving to enhance outcomes for the vulnerable population affected by obesity. We, therefore, sought to overcome controversial aspects in the clinical management of heart disease in patients with overweight/obesity and present evidence on cardiometabolic outcomes associated with currently available weight management interventions, with the objective of equipping clinicians with an evidence-based approach to recognize and address CVD risks associated with obesity.

Pakistan Journal of Medical Sciences 2024To determine trend of following medical advice and safety of high-risk diabetic patients during Ramadan practicing updated IDF DAR guidelines.
OBJECTIVE
To determine trend of following medical advice and safety of high-risk diabetic patients during Ramadan practicing updated IDF DAR guidelines.
METHODS
The cross-sectional study was conducted at Outpatient Department of Diabetes, Endocrinology and Metabolic Disorders Hayatabad Medical Complex Peshawar, Pakistan from April to June 2022, and comprised of high-risk diabetic patients (>6.0) based on updated IDF-DAR guidelines 2022 intending to fast. A questionnaire was designed to document patient risk factors score, type and duration of diabetes, HbA1c, comorbidities and complications developed during Ramadan. Data was analyzed using SPSS 20.
RESULTS
Among all 130 participants, 78(60%) followed medical advice and did not fast and 52(40%) patients fasted against medical advice during month of Ramadan. Out of 130 participants, 89.2% were having type-2 diabetes Mellitus, 55.4% were female and mean age of participants was 52+14.6.40%. In fasting group, 57.7% were in the age range of 16 to 50 years while in non-fasting group 69.2% participants were more than 50 years old (P-value 0.031). There were 80.8% female participants in fasting group versus 38.5% in non-fasting group (P-value 0.001). Hypoglycemia occurred in 58.3% patients in fasting group and 29.3% non-fasting group. (P-value 0.021). On the other hand, 27.8% patients in fasting group and 55.2% of non-fasting group had hyperglycemia (P-value 0.025).
CONCLUSION
Despite advised against fasting in these high-risk patients as per IDF DAR guidelines, almost half of patients fasted considering fasting a religious obligation. Those who fasted had significant hypoglycemia despite adjustment of medications as in guidelines. There is need of more intensive education before fasting, especially in high-risk diabetic patients.
