The pandemic outbreak of Coronavirus disease 2019 (COVID-19) has drastically changed the picture of global healthcare. With the rapid emergence of novel variants of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that rendered the currently available therapeutic and diagnostic approaches inefficient in containing the transmission of infection, it becomes important to focus on strategies to break the transmission chain. The major approach to contain the spread of infection is the promotion of adequate hand hygiene practices in public as hands are an important source of pathogenic microbes. Hand hygiene is an important part of everyday life for maintaining a healthy and disease-free lifestyle. With the outbreak of the pandemic, people are now understanding the importance of hand hygiene practices. The global market of hand sanitizers has experienced rapid growth and high demand. This review aims to discuss the use of sanitizers during the period of COVID-19 and their role in controlling the transmission of infection. It also focuses on global market trends, the advancements in the development of sanitizer formulations, and the limitations of commercial sanitizers. Therefore, the formulation of an effective hand disinfectant is crucial for preventing future pandemic outbreaks. Full article

This population-based study aimed at providing an overview of drug prescription patterns during pregnancy in the Italian region of Lombardy from 2010 to 2020. The cohort consisted of 780,075 deliveries identified from the regional healthcare utilization databases. The prevalence of drugs’ dispensed prescriptions was estimated as the proportion of pregnant women with at least one prescription out of the total deliveries over the entire pregnancy and by trimester. Drugs were classified according to the Anatomical Therapeutic Chemical code. In addition, interrupted time series analysis was conducted to investigate temporal trends of antibiotics’ use during the onset of the COVID-19 pandemic. A total of 497,515 women (63.8%) used at least a drug, including vitamins and minerals, at some point during pregnancy. Vitamins, minerals, and anti-anaemic preparations were prescribed in 20.8%, 13.3%, and 18.3% of deliveries over the trimesters of pregnancy. Folic acid was the most prescribed drug, with about one woman out of four, followed by iron preparations, progestogen, and antibiotics (prescription rate, respectively: 15.9%, 10.2%, and 9.8%). A decreasing trend in the dispensing of antibiotics emerged during the entire study period; however, a significant further decrease following the spread of the pandemic was observed. Further evidence is needed to monitor the use of drugs during pregnancy, determinants, and implications. Full article

Introduction: Given the increasing adult use of amphetamine and methylphenidate and their high misuse potential, we examined suspected suicide attempts and other intentional misuse and medical outcomes and their associations with co-used other substances among amphetamine and methylphenidate exposure cases aged 50+. Methods: Using the 2015–2021 U.S. National Poison Data System (N = 7701 amphetamine and/or methylphenidate cases), we fit two generalized linear models for a Poisson distribution with a log link function, with suspected suicide attempt versus intentional misuse and major medical effect/death versus other outcomes as the dependent variables. Results: Of all amphetamine/methylphenidate exposure cases, suspected suicide attempts and intentional misuse were 28.4% and 13.2%, respectively. Benzodiazepine use was associated with a higher likelihood, but any illicit drug use was associated with a lower likelihood of suspected suicide attempts compared to intentional misuse. The type of stimulant involved (amphetamine or methylphenidate) was not significant. The co-use of antidepressants (IRR = 1.43, 95% CI = 1.16–1.76), prescription opioids (IRR = 1.48, 95% CI = 1.21–1.81), drugs for cardiovascular disease (IRR = 1.51, 95% CI = 1.20–1.90), antipsychotics (IRR = 1.26, 95% CI = 1.02–1.55), or illicit drugs (IRR = 2.40, 95% CI = 1.82–3.15) was associated with a higher likelihood of major effect/death. Conclusions: Suspected suicide attempts or intentional misuse accounted for more than 40% of amphetamine or methylphenidate exposure cases aged 50+. The higher likelihood of major effect/death in cases involving antidepressants, antipsychotics, and cardiovascular disease drugs also suggests the confounding effects of comorbid mental and physical health problems. Careful monitoring of those who were prescribed amphetamine or methylphenidate and use other substances is needed. Full article

Background: Identifying patients with diabetes mellitus (DM) is often performed in epidemiological studies using electronic health records (EHR), but currently available algorithms have features that limit their generalizability. Methods: We developed a rule-based algorithm to determine DM status using the nationally aggregated EHR database. The algorithm was validated on two chart-reviewed samples (n = 2813) of (a) patients with atrial fibrillation (AF, n = 1194) and (b) randomly sampled hospitalized patients (n = 1619). Results: DM diagnosis codes alone resulted in a sensitivity of 77.0% and 83.4% in the AF and random hospitalized samples, respectively. The proposed algorithm combines blood glucose values and DM medication usage with diagnostic codes and exhibits sensitivities between 96.9% and 98.0%, while positive predictive values (PPV) ranged between 61.1% and 75.6%. Performances were comparable across sexes, but a lower specificity was observed in younger patients (below 65 versus 65 and above) in both validation samples (75.8% vs. 90.8% and 60.6% vs. 88.8%). The algorithm was robust for missing laboratory data but not for missing medication data. Conclusions: In this nationwide EHR database analysis, an algorithm for identifying patients with DM has been developed and validated. The algorithm supports quantitative bias analyses in future studies involving EHR-based DM studies. Full article

Though it is well documented that antidepressants are associated with an increased risk of falls in older adults at the drug class level, the comparative risk between individual antidepressants for fall injury in older adults with depression is unknown. Currently, clinicians are making decisions at the drug class level without consideration of the potential that there could be safer choices within classes. We compared the risk of fall injury among initiators of bupropion, duloxetine, fluoxetine, paroxetine, and venlafaxine to those of (es)citalopram and, separately, sertraline. We performed a retrospective cohort study using the MarketScan^® Medicare Supplemental claims from 2007 to 2019. Individuals had incident depression (washout in previous continually enrolled year) with a first antidepressant claim up to three months after depression diagnosis. Individuals were followed for the first three months of antidepressant use until the first occurrence of fall injury, change/discontinuation of antidepressant, discontinued insurance coverage, or end of study. Propensity score inverse probability of treatment-weighted Cox proportional hazards models estimated hazard ratios (HRs) and 95% confidence intervals for each antidepressant comparison and fall injury. We identified 114,505 individuals (mean age 76.6 years, 68% female, 97% without prior fall). A higher risk of fall injury was associated with initiating bupropion (HR 1.20 to 1.61), duloxetine (HR 1.27 to 1.36), paroxetine (HR 1.14 to 1.22), and venlafaxine (HR 1.22 to 1.34) when compared to (es)citalopram or sertraline. New use of duloxetine, bupropion, paroxetine, and venlafaxine was associated with a higher risk of fall injury compared to (es)citalopram and sertraline. Full article

More than 3 years have passed since the emergence of COVID-19. On 8 May 2023, COVID-19 in Japan was downgraded to Category 5 by the Infectious Disease Control Law. In Japan, at the beginning of the COVID-19 pandemic in 2020, cases of infection and deaths from severe disease were few compared with those in Western countries. However, in the medical field, screening for COVID-19 was given top priority, resulting in confusion and proving disadvantageous for many patients. The overreaction to COVID-19 as the most important issue in society can be attributed largely to statements by infectious disease experts. In addition, the mRNA vaccine emerged in 2021, and most of the population was vaccinated up to two times within a short period of less than 1 year because infectious disease experts strongly promoted vaccination. After 2022, when vaccination progressed and the Omicron strain, which is an attenuated strain, became the mainstay of SARS-CoV-2, the number of severe cases of COVID-19 decreased significantly; however, the number of infected people increased dramatically instead. A significant portion of the population is thought to have hybrid immunity due to vaccination plus natural infection and maintains high antibody titer levels. Henceforth, additional vaccination should be given preferentially to those who will benefit most from it. Conversely, measures against COVID-19 caused serious damage to the economy and society. Policies that not only address countermeasures against infection, but also those that encompass the economy and society as a whole, are necessary. Full article

COVID-19 pandemic-related pressures on primary care may have driven the inappropriate continuation of antibiotic prescriptions. Yet, prescribing modality (repeat/non-repeat) has not previously been investigated in a pandemic context. With the approval of NHS England, we conducted a retrospective cohort study of >19 million English primary care patient records using the OpenSAFELY-TPP analytics platform. We analysed repeat/non-repeat prescribing frequency in monthly patient cohorts between January 2020 and 2022. In-depth analysis was conducted on January 2020 (“pre-pandemic”) and January 2021 (“pandemic”) cohorts (with a particular focus on repeat prescribing). Per-patient prescribing and clinical conditions were determined by searching primary care records using clinical codelists. Prescriptions in a 6-month lookback period were used to delineate repeat prescribing (≥3 prescriptions) and non-repeat prescribing (1–2 prescriptions). Associations between demographics (e.g., age, sex, ethnicity) and prescribing were explored using unadjusted risk ratios. The frequency of clinical conditions among prescribed patients was examined. Antibiotic prescribing declined from May 2020; non-repeat prescribing declined more strongly than repeat prescribing (maximum declines −26% vs. −11%, respectively). Older patients were at a higher risk of prescribing (especially repeat prescribing). Comorbidities were more common among repeat- vs. non-repeat-prescribed patients. In the pandemic cohort, the most common clinical conditions linked to repeat prescribing were COPD comorbidity and urinary tract infection. Our findings inform the ongoing development of stewardship interventions in England, targeting patient groups wherein there is a high prevalence of repeat prescribing. Full article

Late adverse events (LAEs) are an important cause of illness and disability in childhood cancer survivors (CCSs) and increase the risk of mortality. The aim of this cross-sectional study was to describe the frequency and severity of treatment-related LAEs in Mexican CCSs. The study period was between September 2018 and April 2019. We tested a sample of 82 CCSs at the Hospital Infantil de México Federico Gómez. We considered an LAE to be any medical effect related to treatment after ending cancer therapy. All LAEs were classified according to severity (using the grades of Common Terminology Criteria for Adverse Events v.5.0), diagnosis and time of occurrence after treatment. The treatment-related LAE frequency was 11.0% (95% CI; 4.2–17.8%). A total of 11 LAEs were identified in nine patients. Slightly over half of the patients were male (54.9%). The most frequent diagnosis was acute lymphoblastic leukemia (45.1%). The body systems involved in LAEs were the endocrine (55.6%), neurological (22.2%), auditory (11.1%) and renal (11.1%) systems. Obesity was the most frequent LAE (45.4%). Most LAEs were classified as grade 1 and 2 (60%). The median follow-up was 6.5 years. The odds ratio was used as a measure of association to identify characteristics associated with the LAEs. We identified that the age at diagnosis (OR = 0.71, 95% CI, 0.51–0.99; p = 0.046) and chemotherapy-only group (OR = 0.03, 95% CI, 0.00–0.86, p = 0.040) were associated with LAEs. This is the first study that describes the frequency and severity of LAEs in Mexican childhood cancer survivors. Full article

Background: The extensive use of antibiotics has contributed to the development of antibiotic resistance. Understanding the factors behind the attitude of physicians in prescribing antibiotics may be useful to address educational interventions to sensitize them to a more rational use of these drugs. This study aimed to evaluate the general practitioners’ (GPs) characteristics potentially associated with antibiotic prescription in community-dwelling adults from 2000 to 2019. Method: Multivariable linear regression models were performed to evaluate the association of GPs’ characteristics with the mean number of different antibiotics prescribed and the mean number of Defined Daily Doses (DDD) prescribed per patient. Results: We found that GPs older than 60 years prescribed a smaller number of different antibiotics per patient compared to 30–40 years old GPs (mean (standard error) 1.4 (0.5) vs. 1.8 (0.4)). In contrast older GPs prescribed more DDD compared to younger ones (28.9 (0.1) vs. 27.3 (0.3)). GPs prescribed 29 (0.1) DDD for >200 patients on polypharmacy vs. 28 (0.1) DDD for <100 patients on polypharmacy. The mean number of DDD prescribed increased by 5 units and by 16 units for each refill and switch, respectively. Conclusions: Age and number of patients in polypharmacy in charge were found to be associated with higher antibiotic prescriptions. The knowledge of the GPs-related factors could allow the stakeholders to design interventions to sensitize them to a more appropriate use of antibiotics in view of the increasing issue of antibiotic resistance.

We examined eligibility criteria from recent oncology clinical trials to see whether real-world data (RWD) from electronic health records (EHRs) could be used to create external control groups for clinical trials. Trials were identified from the Aggregate Analysis of ClinicalTrials.gov database; the selected trials were for oncology drugs approved by the FDA in 2020. Verbatim text from trial inclusion and exclusion criteria was qualitatively assessed by an expert panel to determine if criteria could be ascertained from structured and unstructured EHR data. Identified criteria were categorized (cancer-related, comorbidity-related, demographic, functional status, and trial operations) and subcategorized. Among 53 identified trials, 20 met the requirements for study inclusion, which included 463 eligibility criteria. Percentages of criteria by category were as follows: cancer-related factors (46%), comorbidities (20%), functional status (18%), trial operations (14%), and demographics (2%). For 18 of the 20 trials, 80% of the eligibility criteria could be ascertained with RWD; for 4 of the 20, it was 100%. When trial operation-specific criteria were excluded, all 20 met the 100% threshold. Our study indicates that both structured and unstructured data from community-based oncology-specific EHRs can be used for determining patient eligibility for external control arms for clinical trials.

This study aimed to systematically review and explore the impact of study methods on the cost of managing adverse drug reactions (ADRs) among hospitalized patients to guide policymakers and researchers. A literature search was conducted in MEDLINE, EMBASE, CINAHL, Cochrane Library, and Google Scholar. The search was restricted to studies from 2000 to 2017. Two authors independently reviewed the studies, assessed their risk of bias, and extracted information for analysis. Data abstraction was based on the study design, ADR reporting, and costing approaches. Of 677 studies identified, 12 were included for analysis. All studies defined ADR according to WHO classifications. The percentage of admission due to ADR ranged from 0.03% to 17.11%. All studies adopted a healthcare provider perspective, using either a micro-costing (n = 7), case-mix group costing (n = 3), or average-per-diem costing (n = 2) approach. The cost per ADR widely fluctuated from USD 65.00 to USD 12,129.90 based on various factors. The micro-costing approach generally had a lower cost compared to other approaches. The cost per ADR in high-income countries was also 10 times higher than in lower- or middle-income countries. This study evidenced that the methodological heterogeneity across studies has resulted in a wide range of cost estimations for ADR management. Full article

Propylene glycol (PG) and benzyl alcohol (BA) have been shown to inhibit the metabolizing enzyme for acetaminophen in the liver. Ethanol has unpredictable effects on acetaminophen metabolism. Critically ill neonates commonly receive drug formulations containing PG, BA, and ethanol as excipients. Until now, there have been no reports on the influence of BA, PG, and ethanol as excipients in patients undergoing concomitant acetaminophen therapy. We devised the present study to evaluate whether any significant differences in plasma acetaminophen concentrations, liver function tests, and serum creatinine exist between neonates receiving excipients containing drugs compared to those without. We included neonates that were administered intravenous acetaminophen with at least one concomitant drug containing either BA, PG, or ethanol as excipients. Plasma acetaminophen concentrations and levels of liver function were evaluated using tests. The doubling of alanine aminotransferase levels was considered to be a marker of hepatotoxicity. Elevation of serum creatinine >1.5 times higher than the baseline value was considered to be indicative of an acute kidney injury. Fifty-seven neonates were recruited in the study. No significant differences in the serum acetaminophen concentrations, liver and renal function tests, and rates of successful closure of ductus arteriosus were observed between the groups. No significant changes in the serum acetaminophen levels and the clinical outcomes were observed due to the presence of BA, PG, or ethanol in concomitant drugs as excipients. Probably, drugs containing these excipients can be safely administered, and even formulations containing these excipients with acetaminophen are likely to be safe for critically ill neonates.

People with HIV (PWH) experience higher rates of cardiovascular events (CVEs) compared with the general population. A substantial body of evidence supports that select biomarkers of inflammation (soluble CD14 [sCD14], soluble CD163 [sCD163], highly sensitive C-reactive protein [hs-CRP], interleukin-6 [IL-6]) and coagulation (D-dimer) are elevated in PWH and related to increased rates of CVEs. Our previous work showed that smoking compared with nonsmoking was associated with significantly elevated sCD14, a biomarker of monocyte activation. We aimed to explore the effect of electronic cigarette (EC) provision on inflammatory biomarkers in PWH who smoked daily and then switched to an EC. Nineteen PWH were enrolled in a pilot study in which an EC and e-liquid were provided weekly for 8 weeks. Blood specimens for inflammatory biomarker analysis were obtained at baseline (BL) and at week 8. Biomarker levels were high at BL and did not differ significantly at week 8. There were small nonsignificant reductions in sCD163 and CRP levels. Non-significant increases in IL-6, D-dimer, and sCD14 levels were also noted. Use of ECs for 8 weeks does not appear to significantly increase or decrease inflammatory biomarker levels in SWH. Further research with larger samples and a control group is needed. Full article

COVID-19 antiviral medications approved or authorized for emergency use by the U.S. Food and Drug Administration are reported to have high efficacy in preventing severe illness, hospitalizations, and deaths. However, reports for some of these antivirals use relative risk reductions from clinical trials without absolute risk reductions. The present paper reappraises recently published clinical trial data for the COVID-19 antivirals paxlovid, remdesivir, and molnupiravir, and reports absolute risk reductions, relative risk reductions, as well as number needed to treat to reduce severe illness, hospitalizations, and deaths. Relative risk reductions are 88.88% for paxlovid (95% CI: 72.13–95.56%), 86.48% for remdesivir (95% CI: 41.41–96.88%), and 30.41% for molnupiravir (95% CI: 0.81–51.18%), while absolute risk reductions are much lower at 5.73% for paxlovid (95% CI: 3.79–7.68%), 4.58% for remdesivir (95% CI: 1.79–7.38%), and 2.96% for molnupiravir (95% CI: 0.09–5.83%). Low absolute risk reductions and the high number of patients needed to treat to reduce severe COVID-19 infections, hospitalizations, and deaths challenge the clinical efficacy of antivirals approved or authorized by the U.S Food and Drug Administration. These findings apply to other populations with similar control event rates. Accurate information should be disseminated to the public when selecting treatments for COVID-19. Full article

Atrial fibrillation has been described as a global epidemic with a three-fold increase in prevalence in the last 50 years. As the prevalence of atrial fibrillation continues to grow, multiple landmark trials have been designed to determine the best method to treat atrial fibrillation. Initial trials have stated that rate control was not inferior to rhythm control, however, as the efficacy of rhythm control of atrial fibrillation has improved, a benefit in rhythm control has been shown. Because of this trend towards increased rhythm control, more patients have been placed on anti-arrhythmic medications. This paper will review the epidemiology and clinical impact of the utilization of anti-arrhythmic medications. As we enter the era of rhythm control, increased awareness is needed regarding the monitoring and potential adverse events that can occur with these medications. Providers must balance the increased emphasis on rhythm control with the overall clinical impact on their patients due to drug-to-drug interactions and adverse effects that can occur with different co-morbidities. If the clinical momentum towards rhythm control continues, real-world data analysis will be needed to evaluate the clinical impact of the use, risk, and benefits of anti-arrhythmic medications.
