Relative Bioavailability and Food Effect of Asciminib Pediatric Mini-tablet Formulation Compared to the Reference Tablet Formulation in Healthy Adult Participants.

Asciminib, a first-in-class allosteric BCR::ABL1 inhibitor that works by Specifically Targeting the ABL Myristoyl Pocket (STAMP) is used in the treatment of chronic myeloid leukemia. We describe a randomized, single-dose, open-label, four-period crossover study in healthy adult participants (N = 24) which evaluated the relative bioavailability of a single 40-mg dose of asciminib in pediatric formulation (1-mg mini-tablets) compared with the reference adult tablet under fasted conditions. Additionally, the effect of food on the bioavailability of the mini-tablet formulation was evaluated. Under fasted conditions, asciminib exposure was similar for both formulations (geometric mean [Gmean ] area under the concentration-time curve from time 0 to infinity [AUCinf ] 5970 and 5700 ng ×h/mL, respectively). Food decreased the AUCinf and maximum plasma concentration (Cmax ) of the asciminib mini-tablets; this effect was more pronounced with a high-fat meal (Gmean ratios [90% confidence interval]: fasted/low-fat meal, 0.42 [0.38-047], 0.32 [0.28-0.37], respectively; fasted/high-fat meal, 0.30 [0.27-0.34], 0.22 [0.19-0.25], respectively). The mini-tablets were assessed to be easy to ingest with good palatability. Asciminib doses for a pivotal pediatric clinical trial will be defined using physiologically based pharmacokinetic modeling, which will consider the age and the higher food effect observed with the mini-tablets.

Allergen-specific immunotherapy and COVID-19: What happened?

BACKGROUND: The COVID-19 infection played a key role in the discontinuation of patient treatment, such as allergen-specific immunotherapy, in chronic diseases. OBJECTIVES: We conducted a retrospective observational study at Verona University Hospital, Verona, Italy, to assess the level of adherence to sublingual immunotherapy (SLIT) in patients affected by allergic rhinitis and mild asthma. MATERIALS AND METHODS: We compared and analysed data related to first prescription and collection of 5-grass-pollen 300-index of reactivity (IR) SLIT and tablet lyophilisate, containing 75,000 standardized quality tablet units (SQ-T) allergen extract of grass-pollen from Phleum pratense L, for the five-year period 2017-2021.In particular we considered the group of naïve patients from 2017 who completed pre-COVID treatment (2017-2019) and the group of naïve patients from 2019 who completed treatment during the COVID period (2019-2021). The significance test used was Student's t-test, and P ˂ 0.05 was considered as statistically significant. RESULTS: In the three-year period 2017-2019, 264 naïve patients began treatment in 2017, of these 181 continued in 2018, 135 continued in 2019. Instead, for the period 2017-2019, there were 226 naïve patients in 2019; of these 139 continued in 2020, and 102 in 2021. CONCLUSIONS: COVID-19 did not seem to influence adherence to SLIT, which declined independently even in during the pre-pandemic 3-year period.

High persistence and low adverse events burden in cladribine treated MS patients from Argentina.

BACKGROUND: Early initiation with high efficacy therapies seems to be better than an escalation approach in terms of disability prevention in patients with relapsing-remitting MS (RRMS). Although efficacy and safety of cladribine tablets have been shown in clinical trials, real-world evidence (RWE) studies from Latin America are scarce. OBJECTIVE: To describe the baseline characteristics of patients enrolled in the Argentina Patient Support Program (PSP) for cladribine tablets (Adveva®), with at least 1 treatment course, evaluate treatment persistence, adverse event reports from PSP patients and reported relapses characterization. METHODS: Anonymized data routinely collected by Adveva® team of patients that received the first dose of cladribine from April 16th 2018 to March 31st 2021 were analyzed. Treatment persistence was defined as the percentage of patients that initiated year 2 (Y2) from the population of patients with elapsed time since year 1 (Y1) cladribine tablet initiation of at least 18 months. In addition, using the pharmacovigilance data, reported adverse events and the time elapsed from treatment initiation to relapse were analyzed. RESULTS: The present analysis included 269 patients (mean age: 41.7 ± 16 years) that had initiated Y1 of cladribine tablets treatment between April 16th 2018 and March 31st 2021. Although only 29.4% (79/269) of our population was treatment naïve, the ratio of naïve/switch patients that initiated cladribine tablets increased from April 2018-March 2019 to April 2020-March 2021. From the 110 patients with elapsed time since treatment initiation ≥18 months, 101 patients initiated Y2 indicating a persistence level of 91.8%. During follow-up, 425 adverse events were reported, mainly MS relapse (8.9%, 38/425), fatigue (3.8%, 16/425) and headache (3.5%, 15/425). Lymphopenia and infections were rarely reported by RRMS patients treated with cladribine tablets. MS relapse was more frequently reported in patients switching from a previous treatment (87.5%, 27/32) than in the naïve cohort (12.5%, 5/32). CONCLUSIONS: The first real life experience in RRMS patients from Latin America demonstrated that the Adveva® enrolled support program patients have a high persistence level to oral treatment with cladribine tablets. Our results also confirmed the known safety profile of cladribine tablets, with a low incidence of lymphopenia and infections.

Research Progress of Raman Spectroscopy and Raman Imaging in Pharmaceutical Analysis.

The analytical investigation of the pharmaceutical process monitors the critical process parameters of the drug, beginning from its development until marketing and post-marketing, and appropriate corrective action can be taken to change the pharmaceutical design at any stage of the process. Advanced analytical methods, such as Raman spectroscopy, are particularly suitable for use in the field of drug analysis, especially for qualitative and quantitative work, due to the advantages of simple sample preparation, fast, non-destructive analysis speed and effective avoidance of moisture interference. Advanced Raman imaging techniques have gradually become a powerful alternative method for monitoring changes in polymorph distribution and active pharmaceutical ingredient distribution in drug processing and pharmacokinetics. Surface-enhanced Raman spectroscopy (SERS) has also solved the inherent insensitivity and fluorescence problems of Raman, which has made good progress in the field of illegal drug analysis. This review summarizes the application of Raman spectroscopy and imaging technology, which are used in the qualitative and quantitative analysis of solid tablets, quality control of the production process, drug crystal analysis, illegal drug analysis, and monitoring of drug dissolution and release in the field of drug analysis in recent years.

A Prescription for Internet: Feasibility of a Tablet Loaner Program to Address Digital Health Inequities.

OBJECTIVE: The coronavirus disease 2019 pandemic accelerated the adoption of telehealth technologies. Persistent disparities in telecommunication devices, internet connectivity, and digital literacy, however, undermine the potential for telemedicine to reduce barriers to health care access. Health systems may have a role in addressing these structural inequities. We describe the operationalization and feasibility of an internet-enabled tablet loaner program at a freestanding children's hospital. METHODS: Between October 2020 and October 2021, pediatricians enrolled families through ambulatory clinics at an academic urban freestanding children's hospital. Eligibility criteria included difficulty accessing virtual care due to lack of stable internet or device. Tablets featured an unlimited data package, access to the patient portal, and virtual visit platform. A private technology company managed device configuration and distribution. To characterize program impact, we compared the proportion of completed clinical encounters during the intervention compared with a preintervention period (March 2020-October 2020) and conducted a qualitative survey with program participants. Participant and visit characteristics were obtained from the electronic medical record and summarized with descriptive statistics. RESULTS: A total of 111 families participated in the tablet loaner program, the majority of whom were Hispanic (51.4%) and black, non-Hispanic (26.1%), and publicly insured (64.9%). Between the preintervention and intervention periods, there was a significant increase in completed video- and phone-based virtual visits (75.3 vs. 79.1%, p = 0.038). The proportion of video-based only visits increased from 82.9 to 88.9%. p < 0.001. Families reported that the tablet improved the patient's ability to receive medical care (93.7%) and was easy to use (93.9%). CONCLUSION: The tablet loaner initiative was associated with an improvement in markers of virtual visit engagement and health care experience. Efforts to expand telemedicine equity must consider technological access and digital literacy as well as broad coalitions across industry, government, and community organizations.

Overcoming Access Barriers for Veterans: Cohort Study of the Distribution and Use of Veterans Affairs' Video-Enabled Tablets Before and During the COVID-19 Pandemic.

BACKGROUND: During the COVID-19 pandemic, as health care services shifted to video- and phone-based modalities for patient and provider safety, the Veterans Affairs (VA) Office of Connected Care widely expanded its video-enabled tablet program to bridge digital divides for veterans with limited video care access. OBJECTIVE: This study aimed to characterize veterans who received and used US Department of VA-issued video-enabled tablets before versus during the COVID-19 pandemic. METHODS: We compared sociodemographic and clinical characteristics of veterans who received VA-issued tablets during 6-month prepandemic and pandemic periods (ie, from March 11, 2019, to September 10, 2019, and from March 11, 2020, to September 10, 2020). Then, we examined characteristics associated with video visit use for primary and mental health care within 6 months after tablet shipment, stratifying models by timing of tablet receipt. RESULTS: There was a nearly 6-fold increase in the number of veterans who received tablets in the pandemic versus prepandemic study periods (n=36,107 vs n=6784, respectively). Compared to the prepandemic period, tablet recipients during the pandemic were more likely to be older (mean age 64 vs 59 years), urban-dwelling (24,504/36,107, 67.9% vs 3766/6784, 55.5%), and have a history of housing instability (8633/36,107, 23.9% vs 1022/6784, 15.1%). Pandemic recipients were more likely to use video care (21,090/36,107, 58.4% vs 2995/6784, 44.2%) and did so more frequently (5.6 vs 2.3 average encounters) within 6 months of tablet receipt. In adjusted models, pandemic and prepandemic video care users were significantly more likely to be younger, stably housed, and have a mental health condition than nonusers. CONCLUSIONS: Although the COVID-19 pandemic led to increased distribution of VA-issued tablets to veterans with complex clinical and social needs, tablet recipients who were older or unstably housed remained less likely to have a video visit. The VA's tablet distribution program expanded access to video-enabled devices, but interventions are needed to bridge disparities in video visit use among device recipients.

Vaccination Opportunities in Multiple Sclerosis Patients Treated with Cladribine Tablets.

COVID 19 pandemic and mass vaccination campaigns have revealed the situation of the most vulnerable patients. In this work, we focused our attention to patients who have Multiple Sclerosis (MS), particularly in treatment with cladribine tablets, trying to understand if and when it is possible to administer the vaccine successfully. In light of the novel topic, we studied the existing literature and analysed experiences with previous vaccinations, such as influenza and VZV, as well as data from countries where vaccination campaigns had already begun. Overall, we have taken into account the mechanism of action, the pharmacokinetic/pharmacodynamic of cladribine, and the changes in the immune system after its administration, together with the preliminary data about the humoral response to influenza, VZV, and SARS-CoV-2 vaccinations in cladribine treated patients. In conclusion, data showed that the use of cladribine tablets seems to permit flexibility regarding vaccination timing and we suggest that vaccination in those patients should be safe and effective. The current COVID 19 pandemic has re-ignited the interest in vaccines and vaccination procedures. The importance of including fragile individuals has increased as a result of mass vaccination. Millions of patients with multiple sclerosis (MS) around the world are debating whether they can safely receive their vaccine shot with the same efficacy despite receiving immune-modulating or immune-suppressive treatments. In the absence of conclusive empirical data, we will review and discuss the available evidence and the reasonable conclusions for one specific treatment, namely cladribine tablets (Mavenclad).

Simultaneous determination of nirmatrelvir and ritonavir in human plasma using LC-MS/MS and its pharmacokinetic application in healthy Chinese volunteers.

Paxlovid, a copackaged medication of nirmatrelvir tablets (150 mg) and ritonavir tablets (100 mg) developed by Pfizer, is one of the first orally accessible COVID-19 antiviral medicines to be approved for emergency usage. In this research, an efficient LC-MS/MS method for simultaneous determination of nirmatrelvir and ritonavir in human plasma was established and validated with remdesivir as an internal standard. Chromatographic separations were carried out on a Thermo BDS Hypersil C18 column (4.6 × 100 mm, 2.4 µm) using deionized water and methanol as mobile phase, both added with 0.1% (v/v) formic acid. Based on the positive electrospray ionization mode, nirmatrelvir and ritonavir were analyzed by selective reaction monitoring. Excellent precision, accuracy, recovery, and linearity were demonstrated, covering the range of 50-5000 ng/mL for nirmatrelvir and 10-1000 ng/mL for ritonavir. Then, the established method was used for determining the pharmacokinetic profile of Paxlovid in healthy Chinese volunteers. The pharmacokinetic parameters, including Cmax , Tmax , t1/2 , and AUC0 - ∞ of Western volunteers, correspond well with the results of this pharmacokinetic investigation.

Additively manufactured electrodes for the electrochemical detection of hydroxychloroquine.

Although studies have demonstrated the inactivity of hydroxychloroquine (HCQ) towards SARS-CoV-2, this compound was one of the most prescribed by medical organizations for the treatment of hospitalized patients during the coronavirus pandemic. As a result of it, HCQ has been considered as a potential emerging contaminant in aquatic environments. In this context, we propose a complete electrochemical device comprising cell and working electrode fabricated by the additive manufacture (3D-printing) technology for HCQ monitoring. For this, a 3D-printed working electrode made of a conductive PLA containing carbon black assembled in a 3D-printed cell was associated with square wave voltammetry (SWV) for the fast and sensitive determination of HCQ. After a simple surface activation procedure, the proposed 3D-printed sensor showed a linear response towards HCQ detection (0.4-7.5 µmol L-1) with a limit of detection of 0.04 µmol L-1 and precision of 2.4% (n = 10). The applicability of this device was shown to the analysis of pharmaceutical and water samples. Recovery values between 99 and 112% were achieved for tap water samples and, in addition, the obtained concentration values for pharmaceutical tablets agreed with the values obtained by spectrophotometry (UV region) at a 95% confidence level. The proposed device combined with portable instrumentation is promising for on-site HCQ detection.

Evaluation of the Effect of Garlic Tablet as a Complementary Treatment for Patients with Diabetic Retinopathy.

Purpose: The aim of this study was to investigate the effectiveness of garlic (Allium sativum L.) tablets as a complimentary herbal medication in diabetic macular edema. Methods: A total of 91 diabetic participants (117 eyes) with central involved macular edema underwent a double-blind randomized trial. The patients used garlic tablets (500 mg) (2 tab/day) or placebo for 4 weeks and subsequently were examined by an expert ophthalmologist. Clinical manifestations including the best-corrected visual acuity (BCVA, logMAR), central macular thickness (CMT, µm), and intraocular pressure (IOP) were measured as the main outcomes. Results: BCVA was significantly improved by a 0.18 decrease in mean logMAR value in the garlic-treated patients in comparison with 0.06 in the control ones (P value = 0.027). CMT was decreased in both groups by a 102.99 µm decrease in the garlic group compared to 52.67 µm in the placebo group, albeit in a nonsignificant manner (P value: 0.094). IOP was decreased in the garlic group by 1.03 mmHg (P value: 0.024) and increased by 0.3 mmHg (P value: 0.468) in the placebo group. Conclusion: Our trial suggests that garlic supplements can improve visual acuity, decrease the CMT and lower the IOP, and can be considered as an adjuvant treatment in patients with diabetic macular edema. Garlic was satisfactorily tolerated in diabetic patients, and no significant adverse effect interrupting the safety profile was observed.

Real-world evidence for cladribine tablets in multiple sclerosis: further insights into efficacy and safety.

Cladribine (CLAD) is a purine nucleoside analog approved in tablet form to treat highly active multiple sclerosis (MS). CLAD tablets are the first oral therapy with an infrequent dosing schedule, administered in two annual treatment courses, each divided into two treatment cycles comprising 4-5 days of treatment. The efficacy and safety of CLAD tablets have been verified in randomized controlled clinical trials. Clinical observational studies are performed in more representative populations and over more extended periods, and thus provide valuable complementary insights. Here, we summarize the available evidence for CLAD tablets from post-marketing trials, including two observational, four long-term extensions, and two comparative studies. The patients in the post-marketing setting differed from the cohort recruited in the pivotal phase III trials regarding demographics and MS-related disability. The limited number of studies with small cohorts corroborate the disease-modifying capacity of oral CLAD and report on a durable benefit after active treatment periods. Skin-related adverse events were common in the studies focusing on safety aspects. In addition, single cases of CLAD-associated autoimmune events have been reported. Lastly, CLAD tablets appear safe regarding COVID-19 concerns, and patients mount a robust humoral immune response to SARS-CoV­2 vaccination. We conclude that the current real-world evidence for CLAD tablets as immune reconstitution therapy for treatment of MS is based on a small number of studies and a population distinct from the cohorts randomized in the pivotal phase III trials. Further research should advance the understanding of long-term disease control after active treatment periods and the mitigation of adverse events.

Longitudinal humoral response in MS patients treated with cladribine tablets after receiving the second and third doses of SARS-CoV-2 mRNA vaccine.

BACKGROUND: Multiple sclerosis (MS) patients receive immunomodulatory treatments which can influence their ability to maintain vaccine specific serological response overtime. MS patients treated with cladribine tablets developed a positive serology response following two doses of mRNA COVID-19 vaccine. However, there is only limited data regarding the effect of cladribine tablets on long-term humoral response after the second and the third booster. METHODS: Serology response to SARS-CoV-2 was tested in healthy controls (HCs) and MS patients treated with cladribine tablets 6 and 9-12 months after the second dose, and 1 and 3-6 months following the third booster-dose of the BTN162b2 mRNA vaccine. RESULTS: Thirty-five out of 36 MS patients treated with cladribine tablets and 100% (46/46) of HCs had a positive serology response up to 10 months after the second vaccine dose. In addition, all cladribine tablets -treated MS patients (22/22) and HCs (24/24) had a positive robust serology response following the third vaccine with a positive humoral response sustain up to 6 months. One month after the third vaccine dose IgG levels were significantly lower in patients treated with cladribine tablets compared to HCs (15,598+11,313 vs 26,394+11,335, p<0.01). Six-month post second vaccine and 3-6 months post third vaccine there was no difference in IgG levels between the groups (1088.0 ± 1072.0 vs 1153.0 ± 997.1, p = 0.79; 5234+4097 vs 11,198+14,679, p = 0.4). CONCLUSION AND RELEVANCE: MS patients treated with cladribine tablets have sustained positive vaccine specific serology response following the second and third SARS-CoV-2 vaccine dose.

Ameliorating Atopy by Compensating Micronutritional Deficiencies in Immune Cells: A Double-Blind Placebo-Controlled Pilot Study.

BACKGROUND: Functional iron deficiency facilitates allergy development and amplifies the symptom burden in people experiencing allergies. Previously we selectively delivered micronutrients to immune cells with ß-lactoglobulin as carrier (holoBLG), resulting in immune resilience and allergy prevention. OBJECTIVE: The clinical efficacy of a food for special medical purposes-lozenge containing ß-lactoglobulin with iron, polyphenols, retinoic acid, and zinc (holoBLG lozenge) was assessed in allergic women. METHODS: In a randomized, double-blind, placebo-controlled pilot study, grass- and/or birch pollen-allergic women (n = 51) were given holoBLG or placebo lozenges over 6 months. Before and after dietary supplementation, participants were nasally challenged and the blood was analyzed for immune and iron parameters. Daily symptoms, medications, pollen concentrations, and well-being were recorded by an electronic health application. RESULTS: Total nasal symptom score after nasal provocations improved by 42% in the holoBLG group versus 13% in the placebo group. The combined symptom medication score during the birch peak and entire season as well as the entire grass pollen season improved in allergic subjects supplemented with the holoBLG lozenge by 45%, 31%, and 40%, respectively, compared with the placebo arm. Participants ingesting the holoBLG lozenge had improved iron status with increased hematocrit values, decreased red cell distribution width, and higher iron levels in circulating CD14+ cells compared with the placebo group. CONCLUSIONS: Targeted micronutrition with the holoBLG lozenge seemed to be effective in elevating the labile iron levels in immune cells and reducing the symptom burden in allergic women in this pilot study. The underlying allergen-independent mechanism provides evidence that dietary nutritional supplementation of the immune system is one of the ways to combat atopy.

Development and validation of capillary zone electrophoresis and high-performance liquid chromatography methods for the determination of oral anticoagulant edoxaban in pharmaceutical tablets.

The incidence of thrombotic complications in SARS-CoV-2 infections has become a global concern; thus, anticoagulants are an integral part of the treatment. Edoxaban (EDX) is an oral anticoagulant suitable for pharmacologic thromboprophylaxis. Herein, two novel analytical methods for EDX determination in tablets are developed and validated using capillary zone electrophoresis (CZE) and high-performance liquid chromatography (HPLC). Operating conditions such as the electrolyte's concentration and pH value, injection time, volume, and the capillary temperature, were optimized. The methods were successfully validated by establishing the linearity, intra- and inter-day precisions (relative standard deviation [%]), accuracy, and robustness. Adequate separation of excipients and degradation products of EDX generated by stress degradation conditions demonstrated the stability-indicating capability of the methods. The analytical procedures were linear in the range of 25-125 µg/ml (r > 0.999), with the limits of detection and quantification of 3.26 and 10.87 µg/ml for CZE and 0.740 and 2.78 µg/ml for HPLC. Although both methodologies are suitable for determining EDX in tablets, CZE provides a greener alternative due to low-cost analysis using less organic solvents and minimizing waste generation.

Improved absorption of itraconazole tablet by co-administration with lemon beverages in a lung transplant recipient: A case report.

After lung transplantation, itraconazole (ITCZ) is used as a prophylaxis for aspergillosis. ITCZ is a weak base with high lipophilicity, and the dissolution and absorption of ITCZ tablets and capsules are pH dependent. Therefore, ITCZ may not achieve sufficient serum concentrations in patients with higher gastric pH because of its poor bioavailability. We report a case of a woman in fifties with post-COVID-19 respiratory failure who successfully underwent lung transplantation, followed by improved bioavailability of ITCZ tablets when given with acidic lemon beverages. The patient was initially administered ITCZ oral solution; this was discontinued because of its unpleasant taste, nausea, and vomiting. The ITCZ oral solution was replaced with ITCZ tablets 78 days after transplantation; however, serum concentrations of ITCZ and hydroxy-ITCZ were below the detection limit (100 ng/mL). We co-administered ITCZ tablets with commercially available lemon beverages. Subsequently, serum concentrations of ITCZ and hydroxy-ITCZ increased to 341 and 673 ng/mL, respectively, on the 125th day after transplantation. Infection with fungi, including Aspergillus spp., was not observed in this case. The patient had no adverse events such as gastric ulcer or hyperglycemia. These results suggest that the co-administration of lemon beverages and ITCZ tablets may help achieve better absorption of ITCZ in patients taking acid suppressants.

Aversion liquid-filled drug releasing capsule (3D-RECAL): A novel technology for the development of immediate release abuse deterrent formulations using a fused deposition modelling (FDM) 3D printer.

COVID19 has caused a significant socioeconomic burden worldwide. Opioid crisis was further intensified with the increasing number of opioid overdose/misuse related deaths in last two years. Abusers have adopted newer/efficient methods for manipulating and abusing commercial opioid formulations. Food and Drug Administration (FDA) has been strategizing tirelessly to prevent misuse/abuse of prescription opioids. One of the strategies is to develop an abuse deterrent formulation (ADF). The current study aims to develop a novel 3D printed drug-releasing capsule shell filled with an aversion liquid (3D-RECAL). Primarily, metformin hydrochloride (MT, model drug) loaded printable filaments of polyvinyl alcohol was prepared using hot melt extrusion. Following extrusion, a 3D printed capsule shell was designed and fabricated using a single nozzle fuse deposition modelling 3D printer. An aversion liquid to be filled in 3D-RECAL capsules was prepared by combining sudan black and sodium polyacrylamide starch in oil base. Mechanical analysis of extruded filaments suggested that the filaments with 20%w/w MT had a higher mechanical strength compared to other drug loadings. Instantaneous gelling and large black non-snortable particles were formed during solvent extraction and physical manipulation studies, respectively. Due to the drug being embedded in the capsule shell, MT release was immediately started with >85% of MT release within 45 mins in 0.1 N HCl. Due to the everlasting need for the newer efficient ADF technologies, 3D-RECAL can be a step in the right direction towards saving lives, providing safe and effective measures to deterring abusers.

Traditional use and safety evaluation of combination Traditional Chinese Medicine in European registration: with XiaoYao Tablets as an example.

Mental health disorders such as stress, anxiety, depression and insomnia caused by COVID-19 have attracted worldwide attention. Traditional Chinese medicines (TCMs) have been proven to be a safe and effective option for treating mental health disorders. Recently, after assessing its efficacy and safety fully, the Netherlands Medicines Evaluation Board approved XiaoYao Tablets as a traditional herbal medicinal product (THMP), indicated for an alternative self-care for patients in Europe to relieve the symptoms of mental stress and exhaustion. Despite the fact that TCMs have gradually become one of the therapeutic choices worldwide, to-date, only a few TCMs have been successfully registered in the European Union (EU) as THMPs, and XiaoYao Tablets is the first successfully registered combination TCM from China. In this article, traditional use efficacy and clinical safety of XiaoYao Tablets in the treatment of mental health disorders were summarized and analyzed from the perspective of traditional use registration (TUR). Additionally a safety evolution pathway of combination TCMs was established. This article will not only seek to enhance our understanding about traditional use efficacy and clinical safety of XiaoYao Tablets, but also summarize the experience of XiaoYao Tablets as the first successfully registered combination TCM from China, which could serve as role model for the others to overcome registration difficulties in the EU.

Mental Health Service Use, Suicide Behavior, and Emergency Department Visits Among Rural US Veterans Who Received Video-Enabled Tablets During the COVID-19 Pandemic.

Importance: Suicide rates are rising disproportionately in rural counties, a concerning pattern as the COVID-19 pandemic has intensified suicide risk factors in these regions and exacerbated barriers to mental health care access. Although telehealth has the potential to improve access to mental health care, telehealth's effectiveness for suicide-related outcomes remains relatively unknown. Objective: To evaluate the association between the escalated distribution of the US Department of Veterans Affairs' (VA's) video-enabled tablets during the COVID-19 pandemic and rural veterans' mental health service use and suicide-related outcomes. Design, Setting, and Participants: This retrospective cohort study included rural veterans who had at least 1 VA mental health care visit in calendar year 2019 and a subcohort of patients identified by the VA as high-risk for suicide. Event studies and difference-in-differences estimation were used to compare monthly mental health service utilization for patients who received VA tablets during COVID-19 with patients who were not issued tablets over 10 months before and after tablet shipment. Statistical analysis was performed from November 2021 to February 2022. Exposure: Receipt of a video-enabled tablet. Main Outcomes and Measures: Mental health service utilization outcomes included psychotherapy visits, medication management visits, and comprehensive suicide risk evaluations (CSREs) via video and total visits across all modalities (phone, video, and in-person). We also analyzed likelihood of emergency department (ED) visit, likelihood of suicide-related ED visit, and number of VA's suicide behavior and overdose reports (SBORs). Results: The study cohort included 13 180 rural tablet recipients (11 617 [88%] men; 2161 [16%] Black; 301 [2%] Hispanic; 10 644 [80%] White; mean [SD] age, 61.2 [13.4] years) and 458 611 nonrecipients (406 545 [89%] men; 59 875 [13%] Black or African American; 16 778 [4%] Hispanic; 384 630 [83%] White; mean [SD] age, 58.0 [15.8] years). Tablets were associated with increases of 1.8 psychotherapy visits per year (monthly coefficient, 0.15; 95% CI, 0.13-0.17), 3.5 video psychotherapy visits per year (monthly coefficient, 0.29; 95% CI, 0.27-0.31), 0.7 video medication management visits per year (monthly coefficient, 0.06; 95% CI, 0.055-0.062), and 0.02 video CSREs per year (monthly coefficient, 0.002; 95% CI, 0.002-0.002). Tablets were associated with an overall 20% reduction in the likelihood of an ED visit (proportion change, -0.012; 95% CI, -0.014 to -0.010), a 36% reduction in the likelihood of suicide-related ED visit (proportion change, -0.0017; 95% CI, -0.0023 to -0.0013), and a 22% reduction in the likelihood of suicide behavior as indicated by SBORs (monthly coefficient, -0.0011; 95% CI, -0.0016 to -0.0005). These associations persisted for the subcohort of rural veterans the VA identifies as high-risk for suicide. Conclusions and Relevance: This cohort study of rural US veterans with a history of mental health care use found that receipt of a video-enabled tablet was associated with increased use of mental health care via video, increased psychotherapy visits (across all modalities), and reduced suicide behavior and ED visits. These findings suggest that the VA and other health systems should consider leveraging video-enabled tablets for improving access to mental health care via telehealth and for preventing suicides among rural residents.

Different Doses, Forms, and Frequencies of Zinc Supplementation for the Prevention of Diarrhea and Promotion of Linear Growth among Young Bangladeshi Children: A Six-Arm, Randomized, Community-Based Efficacy Trial.

BACKGROUND: Children in resource-limited settings remain vulnerable to zinc deficiency and its consequences. OBJECTIVES: To evaluate the effects of different doses, durations, and frequencies of zinc supplementation on the incidence of diarrhea and change in linear growth among young children. METHODS: We conducted a randomized, partially double-blind, controlled, 6-arm, community-based efficacy trial in Dhaka, Bangladesh. Children aged 9-11 mo were randomly assigned to receive 1 of the following interventions for 24 wk: 1) standard micronutrient powder (MNP) containing 4.1 mg zinc and 10 mg iron, daily; 2) high-zinc (10 mg), low-iron (6 mg) (HiZn LoFe) MNP, daily; 3) HiZn (10 mg) LoFe (6 mg)/HiZn (10 mg), no-iron MNPs on alternating days; 4) dispersible zinc tablet (10 mg), daily; 5) dispersible zinc tablet (10 mg), daily for 2 wk at enrollment and 12 wk; 6) placebo powder, daily. Primary outcomes were incidence of diarrhea and change in length-for-age z-score (LAZ) over the 24-wk intervention period. Home visits were conducted twice weekly to assess diarrhea and other morbidity. Incidence and prevalence outcomes were compared among groups with Poisson regression; continuous outcomes were compared using ANCOVA. RESULTS: A total of 2886 children were enrolled between February 2018 and July 2019. The mean incidence and prevalence of diarrhea among all participants was 1.21 episodes per 100 d and 3.76 d per 100 d, respectively. There were no differences in the incidence or prevalence of diarrhea across intervention groups. The decline in LAZ was slightly smaller among children in the daily HiZn LoFe MNP group compared with the placebo powder group (P < 0.05). CONCLUSIONS: The dose of zinc in MNPs as well as the duration and frequency of supplementation evaluated in this trial were not effective in reducing diarrhea; however, the daily HiZn LoFe MNP formulation offered modest improvements in linear growth among young children. This trial was registered at clinicaltrials.gov as NCT03406793.

A Review of Sublingual Sufentanil Tablet (SST) and its Utility as an Analgesic Agent for Pain Procedures.

PURPOSE OF REVIEW: Sedation for pain medicine procedures provides a unique challenge for proceduralists. Many patients dealing with pain are on chronic opioids and require higher doses of sedation for adequate procedural comfort. Chronic pain patients have various comorbidities including depression, neuropsychiatric disorders, peripheral vascular disease, and renal impairment, among others [1]. These confounding variables make the overall treatment of their pain condition much more challenging. RECENT FINDINGS: For patients requiring intravenous (IV) sedation for their pain procedures, the constant need for access may render them a "difficult stick" over time. Another factor to consider is the increasing requirements by the hospital system needing IV sedatives and analgesics in the intensive care unit and operating rooms during the coronavirus (COVID-19) pandemic. Sublingual sufentanil (SST) provides an excellent analgesic option for patients undergoing interventional pain procedures. The use of SST allows hospitals to preserve IV agents for more critical areas and mitigates the difficulty of obtaining IV access in patients.
