The Relationship of Serum 25-Hydroxyvitamin D at Admission and Severity of Illness in COVID-19 Patients

Med J (Ft Sam Houst Tex). 2022 Jul-Sep;(Per 22-07/08/09):54-60.

ABSTRACT

BACKGROUND: COVID-19 is a rapidly propagating respiratory virus causing a global pandemic. At the time of development of this study, not much was known about susceptibility to severe illness, especially without other known risk factors. Retrospective research suggested vitamin D level may correlate with severity of illness. This prospective, observational study seeks to determine if vitamin D level at admission is correlated with severity of illness as determined by needing intensive care unit (ICU)-level care within this first 28 days after admission. This study also looked at the relationship of vitamin D level at admission and mortality, need for ventilator, and number of hospital-free, ICU-free, and ventilator-free days in the 28 days after initial admission.

METHODS: This study is a prospective, observational study of patients admitted to Brooke Army Medical Center (BAMC), San Antonio, TX, for a diagnosis or complication of COVID-19 illness. A vitamin D level was drawn at admission and chart review was used at the end of 28 days after admission to identify outcome measures. Fisher’s Exact test was used for categorical variables, and Kruskal-Wallis test was used for all continuous variables.

RESULTS: Deficient vitamin D level at admission (less than 20ng/mL) was associated with an increased risk of requiring ICU-level care during the 28-day period after initial admission (p=0.028). Secondary outcomes measurements also favored the hypothesis, but none were statistically significant.

CONCLUSIONS: This prospective, observational study further strengthens the hypothesis vitamin D level at admission is correlated with severity of illness in COVID-19 illness; however, this small study was limited in its ability to control for confounders. It does not prove causation, nor does it imply vitamin D supplementation will prevent COVID-19 or improve outcomes in COVID-19. Further research should aim to include a larger cohort to better understand the relationship of vitamin D level and severity of illness in COVID-19 disease.

Efficacy and treatment-related adverse events of multi-targeted tyrosine kinase inhibitors in advanced non-small-cell lung cancer: a meta-analysis of randomized controlled trials

Int J Clin Pharm. 2022 Aug 11. doi: 10.1007/s11096-022-01465-w. Online ahead of print.

ABSTRACT

BACKGROUND: Multitargeted tyrosine kinase inhibitors (TKIs) are used to treat advanced non-small cell lung cancer (NSCLC). Their efficacy and safety have been studied in randomized controlled trials.

AIM: This meta-analysis aimed to summarize the most up-to-date evidence regarding the efficacy and adverse events of TKIs in NSCLC treatment.

METHOD: Randomized controlled trials were searched from PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. The intervention arm was the TKI-containing group, and the control arm was the TKI-free group. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival, and adverse events were extracted and synthesized. The last search was performed in April 2022. Two researchers independently screened articles, extracted data, and evaluated the quality of the included studies. The Cochrane risk-of-bias tool was used to assess the quality of each study. Random or fixed-effect models were used in statistical methods. I2 statistics were used to assess heterogeneity.

RESULTS: Thirty-one studies (12,517 patients) were included. Compared to the control group, the TKI group had significantly higher ORR (relative risk RR 1.52, 95% confidence interval, CI [1.29, 1.80], P < 0.05), DCR (RR 1.34, 95%CI [1.19, 1.51], P < 0.05), and prolonged PFS (hazard ratio HR 0.67, 95%CI [0.59, 0.77], P < 0.05). The TKI group showed a higher rate of adverse events (RR 1.70, 95%CI [1.34, 2.16], P < 0.05) and grade 3-5 adverse events (RR 1.59, 95% CI [1.35, 1.88], P < 0.05).

CONCLUSION: TKIs could increase ORR and DCR and prolong PFS for advanced NSCLC. Adverse events should be closely monitored.

Probabilistic Learning of Cue-Outcome Associations is not Influenced by Autistic Traits

J Autism Dev Disord. 2022 Aug 11. doi: 10.1007/s10803-022-05690-0. Online ahead of print.

ABSTRACT

According to Bayesian/predictive coding models of autism, autistic individuals may have difficulties learning probabilistic cue-outcome associations, but empirical evidence has been mixed. The target cues used in previous studies were often straightforward and might not reflect real-life learning of such associations which requires learners to infer which cue(s) among many to track. Across two experiments, we compared adult learners with varying levels of autistic traits on their ability to infer the correct cue to learn probabilistic cue-outcome associations when explicitly instructed to do so or when exposed implicitly. We found no evidence for the effect of autistic traits on probabilistic learning accuracy, contrary to the predictions of Bayesian/predictive coding models. Implications for the current Bayesian/predictive coding models are discussed.

Improving attribution of extreme heat deaths through interagency cooperation

Can J Public Health. 2022 Aug 11. doi: 10.17269/s41997-022-00672-2. Online ahead of print.

ABSTRACT

Attributing individual deaths to extreme heat events (EHE) in Canada and elsewhere is important for understanding the risk factors, protective interventions, and burden of mortality associated with climate change. However, there is currently no single mechanism for identifying individual deaths due to EHE and different agencies have taken different approaches, including (1) vital statistics coding based on medical certificates of death, (2) probabilistic methods, and (3) enhanced surveillance. The 2018 EHE in Montréal provides an excellent case study to compare EHE deaths identified by these different approaches. There were 353 deaths recorded in the vital statistics data over an 8-day period, of which 102 were potentially attributed to the EHE by at least one approach and 251 were not attributed by any approach. Only nine of the 102 deaths were attributed to the EHE by all three approaches, 23 were attributed by two approaches, and 70 were attributed by only one approach. Given that there were approximately 50 excess deaths during the EHE, it remains unclear exactly which of the total 353 deaths should be attributed to the extreme temperatures. These results highlight the need for a more systematic and cooperative approach to EHE mortality in Canada, which will continue to increase as the climate changes.

Twenty-First Century Global ADR Management: A Need for Clarification, Redesign, and Coordinated Action

Ther Innov Regul Sci. 2022 Aug 11. doi: 10.1007/s43441-022-00443-8. Online ahead of print.

ABSTRACT

Adverse drug reactions (ADRs) are estimated to be between the fourth and sixth most common cause of death worldwide, taking their place among other prevalent causes of mortality such as heart disease, cancer, and stroke. ADRs impact a broad range of populations across a wide variety of global geography and demographics, with significant mortality and morbidity burden in vulnerable groups such as older people, pediatric populations, and individuals in low-income settings. Too large a share of medicines risk management remains limited to signal detection in big ADR databases (USFDA, EMA, WHO, etc.) This resource allocation is antiquated and applied statistical signal detection methodologies have reached their limits of usefulness. In addition, existing databases are designed for short-term reactions, closely related to medication use and, thus, can only partially assess important broader consequences across geography, time, and clinical relevance. There is an urgent need change the dynamic. We need to identify (earlier and more regularly) many of the important but often overlooked or missed ADRs. Rather than assigning blame, we need to identify the root causes of the problem so they can be clearly addressed and fixed. The public health implications are profound-particularly as we recognize the importance of predicting and mitigating the next pandemic. Consequently, medicines risk management must be integrated within a broader global public health vision. To accomplish this, we need to develop the new tools and methodologies critical to assessing these public health imperatives.

Effectiveness of the SMART Sex Ed program among 13-18 year old English and Spanish speaking adolescent men who have sex with men

AIDS Behav. 2022 Aug 11. doi: 10.1007/s10461-022-03806-2. Online ahead of print.

ABSTRACT

Adolescent men who have sex with men (AMSM) have a high HIV incidence and low utilization of testing and prevention services. However, very few HIV prevention programs exist that focus on the unique sexual health needs of AMSM. SMART is a stepped care package of eHealth interventions that comprehensively address the sexual and HIV prevention needs of AMSM. This study examines the impact of the first step of SMART, “SMART Sex Ed,” on 13- to 18-year-old AMSM (n = 983) from baseline to three-month follow-up across 18 separate outcomes measuring HIV prevention attitudes, skills, and behaviors. We observed significant change from baseline to three-month post-intervention in nine HIV-related outcomes (e.g., receipt of HIV and STI test, HIV knowledge), as well as largely consistent effects across demographic subgroups (e.g., race, age, rural, low SES). Analyses observed no effects on condom use behaviors. SMART Sex Ed shows promise as an effective sexual health education program for diverse AMSM.

Dual Energy Computed Tomography Collagen Material Decomposition for Detection of Lumbar Spine Disc Extrusion and Sequestration: A Comparative Study With Greyscale Computed Tomography

Can Assoc Radiol J. 2022 Aug 10:8465371221118886. doi: 10.1177/08465371221118886. Online ahead of print.

ABSTRACT

To assess value of dual energy computed tomography (DECT) collagen material decomposition algorithm when combined with standard computed tomography (CT) in detection of lumbar disc extrusion and sequestration. Materials and Methods: Retrospective analysis of all patients with acute low back pain who had a diagnosis of lumbar spine disc extrusion and/or sequestration on Magnetic Resonance Imaging (MRI) (reference standard), and had undergone non-contrast DECT of the lumbar spine within 60 days of the MRI. Age and sex-matched control patients (n = 42) were included. Patients were grouped into standard, grey-scale CT only group and standard CT + DECT tendon images group. Two double-blinded radiologists reviewed both groups for presence of extrusion or sequestration. They also rated their diagnostic confidence on Likert 5-point scale. McNemar Chi-square test was used to compare diagnostic accuracy, unpaired t-test to compare reviewers diagnostic confidence, and Cohen’s k (kappa) test for interobserver agreement. Results: The combined group showed higher overall sensitivity (96.6% vs 87.2%), specificity (99% vs 95.4%), and diagnostic accuracy (98.7% vs 94.5%) with a lower false positive rate (1.1% vs 4.6%). McNemar Chi-square test confirmed statistical significance (P = .03 and P = .02 for Reviewers R1 and R2, respectively). The mean diagnostic confidence was also significantly higher on combined group (R1: 3.74 ± 1.1 vs 3.47 ± 1.15 (P < .01) and R2: 3.91 ± 1.15 vs 3.72 ± 1.16 [mean ± SD] (P = .02)). Conclusion: Utilizing MRI as a reference standard, DECT tendon application combined with standard CT increases the sensitivity, specificity, and accuracy of detection of lumbar spine disc extrusion and sequestration, when compared to standard CT alone.

Pharmacovigilance of cutaneous adverse drug reactions in associations with drugs and medical conditions: a retrospective study of hospitalized patients

BMC Pharmacol Toxicol. 2022 Aug 10;23(1):62. doi: 10.1186/s40360-022-00603-4.

ABSTRACT

BACKGROUND: Cutaneous adverse drug reaction (CADR) is a common problem in clinical medication. This study aimed to investigate the correlation between clinical drug application and CADR occurrence as evidence for preventive strategies and rational clinical drug use.

METHODS: We analyzed the characteristics of CADRs of 858 patients admitted to Shandong Provincial Third Hospital from March 2007 to December 2018. The most significant drugs concerning the common skin symptoms and their significance to CADR were investigated by case-non-case and multiple logistic regression analyses.

RESULTS: A total of 266 drugs were involved in 858 cases of CADR. Among the ten most relevant medications, primarily antibiotics and herbal injections, and nutritional support drugs, potassium sodium dehydroandrographolide succinate injection, and cefoperazone sodium and sulbactam sodium injection were found to be 2.1 and 1.45 times statistically more prone to CADRs than to other adverse drug reactions (ADRs), respectively. The main route of administration was intravenous (63.16%), with oral administration accounting for 25.19%. There were 747 cases of ADR, 71 of severe ADR, 2 of new and severe ADRs, and 38 cases of new ADR. Overall, 100 cases of CADR exhibited abnormal alanine aminotransferase, aspartate aminotransferase, and serum creatinine levels. The predictive factors for severe CADR occurrence included allergy and smoking histories, cefoperazone sodium, sulbactam sodium injection, levofloxacin lactate and sodium chloride injection.

CONCLUSIONS: Drug-induced CADR symptoms are commonly associated with other ARDs, predominantly rashes and pruritus, and are often accompanied by some medical conditions, especially liver and kidney damage. Detailed attention to a patient’s primary diseases, allergy history, and drug safety profile could help prevent or reverse CADR in most patients.

No travel worsens depression: reciprocal relationship between travel and depression among older adults

Ann Gen Psychiatry. 2022 Aug 10;21(1):31. doi: 10.1186/s12991-022-00405-2.

ABSTRACT

BACKGROUND: The aim of this study was to examine the bidirectional relationship between depression and travel.

METHOD: We analyzed 8524 participants’ data obtained from the 2008 to 2016 waves of the Korean Longitudinal Study of Ageing, a prospective cohort study. Depression was diagnosed using the Center for Epidemiological Studies Depression Scale: 10-Items (CES-D10), with scores of 4 or higher indicating depression. We used a generalized estimating equation and a cross-lagged panel model for statistical analysis.

RESULTS: Participants who had not traveled for one year had a 71% higher risk of suffering from depression in the following year than did those who had traveled [relative risk (RR) = 1.71, P < 0.001], and participants with depression had more than double the increased risk of not traveling than did those not currently suffering from depression (RR = 2.08, P < 0.001). The cross-lagged panel model confirmed the vicious cycle involving the amount of travel and score on the CES-D10; individuals who traveled more frequently were more likely to have lower scores on the CES-D10 (coefficient = – 0.04 to – 0.03, Ps < 0.01), and individuals with higher scores were less likely to travel (coefficient = – 0.06 to – 0.03, Ps < 0.01).

CONCLUSIONS: The risk of depression increases for people who do not travel, and a reciprocal relationship exists between travel and depression.

The positive impact of a care-physical activity initiative for people with a low socioeconomic status on health, quality of life and societal participation: a mixed-methods study

BMC Public Health. 2022 Aug 10;22(1):1522. doi: 10.1186/s12889-022-13936-w.

ABSTRACT

BACKGROUND: Overweight and obesity rates are increasing worldwide, particularly among people with a low socioeconomic status (SES). Care-physical activity (care-PA) initiatives may improve participants’ lifestyles and thereby lower overweight and obesity rates. A two-year care-PA initiative specifically developed for citizens with a low SES, X-Fittt 2.0, was offered free of charge to participants, and included 12 weeks of intensive guidance and sports sessions, and 21 months of aftercare. Here, we study the impact of X-Fittt 2.0 on health, quality of life (QoL) and societal participation using a mixed-methods design.

METHODS: Questionnaires and body measurements were taken from 208 participants at the start of X-Fittt 2.0 (t0) and after 12 weeks (t1), one year (t2) and two to three years (t3). We also held 17 group discussions (t1, n = 71) and 68 semi-structured interviews (t2 and t3). Continuous variables were analysed using a linear mixed-model analysis (corrected for gender, age at t0, height, education level and employment status at the different time points), while we used descriptive statistics for the categorical variables. Qualitative data were analysed using a thematic analysis.

RESULTS: Body weight was significantly lower at all three post-initiative time points compared with the baseline, with a maximum of 3.8 kg difference at t2. Body Mass Index, waist circumference, blood pressure and self-perceived health only significantly improved during the first 12 weeks. A positive trend regarding paid work was observed, while social visits decreased. The latter might be explained by the COVID-19 pandemic, as lockdowns limited social life. Furthermore, participants reported increased PA (including sports) and a few stopped smoking or drinking alcohol. Participants mentioned feeling healthier, fitter and more energetic. Additionally, participants’ self-esteem and stress levels improved, stimulating them to become more socially active. However, the participants also mentioned barriers to being physically active, such as a lack of money or time, or physical or mental health problems.

CONCLUSIONS: X-Fittt 2.0 improved the health, QoL and societal participation of the participants. Future initiatives should take into account the aforementioned barriers, and consider a longer intervention period for more sustainable results. More complete data are needed to confirm the findings.
