Suboptimal uptake, retention, and adherence of daily oral PrEP among people with OUD receiving HCV treatment

Introduction Daily oral pre-exposure prophylaxis (PrEP) with tenofovir/emtricitabine (TDF/FTC) prevents HIV among people who inject drugs (PWID). Despite rising HIV incidence and injection drug use, PrEP use remains low and there is limited research about uptake, adherence, and retention among PWID. Methods The ANCHOR investigation evaluated a community-based care model collocating hepatitis C (HCV) treatment, medication for opioid use disorder (OUD), and PrEP in individuals in Washington, DC-Baltimore. PrEP counseling was conducted from HCV treatment Day 0 until Week 24. Subjects could start any time during this window, were followed for 48 weeks, and were assessed for adherence by self-report and dried bloodspot TDF analysis. Results 198 participants were enrolled, of whom 185 (93%) were HIV-negative. Twenty-nine individuals (15.7% of HIV-negative cohort) initiated PrEP. 116 participants (62.7%) met 2014 CDC PrEP criteria due to IDU (82, 44.3%), sex (9, 4.9%), or both practices (25, 13.5%). Providers recommended PrEP to 94 individuals (50.8%), and recommendation was associated with PrEP uptake. Median treatment duration was 104 days (IQR 28, 276), with 8 participants retained through Week 48. Adherence was variable over time by self-report and declined by TDF analysis. No HIV seroconversions occurred. Conclusions This cohort of people with HCV and OUD experienced low uptake of PrEP despite the majority meeting CDC criteria. High rates of disruption and discontinuation, compounded by variable adherence, made TDF/FTC a suboptimal prevention strategy. Emerging modalities like long-acting formulations may address these barriers, but PWID have been excluded from their development to date.

Toxicology of Ngirimbo: Analysis to Determine the Levels of Trace and Heavy Metals, Moisture, Nicotine, pH and Microbial Assessment.

Introduction: Tobacco and other similar/related products represent a substantial proportion of recreationally-used substances in Malawi. Ngirimbo is a smokeless substance taken orally to reduce tobacco smoking. This study aimed to determine the toxicological characteristics of Ngirimbo in terms of pesticide residues, microbial, trace and heavy metal contaminants, herbal compounds, and nicotine, moisture, and pH levels. Methods: Samples were analysed using atomic absorption spectrophotometry, titration, X-ray fluorescence spectroscopy, UV-visible Spectrophotometer, gas chromatography-mass spectrometry, pH and gravimetric analysis, ISO4833, ISO21527, ISO16654, and ISO6579. Results: From a total of 12 samples, 5 samples contained nicotine ranging from 0.08–0.84%, while the remaining 7 samples showed no trace of nicotine. Sample pH ranged from 6.68 to 8.32, and moisture content from 12.87–47.11%. Samples had no detectable contamination with chlorine or pesticide residue. Heavy metals tested: Cadmium, Nickel, Lead, and Copper were found to be below the detection limit of 0.01mg/kg. On the other hand, X-ray fluorescence spectroscopy analysis revealed the presence of Nickel, Bromine, Rubidium, Strontium, Zirconium, Molybdenum, Rhodium, Cadmium, Chromium, and Tellurium. Samples had good levels of Calcium, Iron, Potassium, Sodium, and Zinc ranging from 23mg/kg to 57,800mg/kg. Samples contained phytocompounds and herbal material of medicinal relevance. In terms of the microbiological content, Escherichia coli and Salmonella were absent, while Moulds and Yeast were present at a level of <1cfu/g, with the total plate count varying across all samples between 1,400cfu/g and 640,000cfu/g. Conclusion: These findings demonstrate that the current state of Ngirimbo available in Malawi is toxic and a hazard to human health. Implications: Prolonged use of Ngirimbo may lead to users developing mouth cancers or thermal burns to the oral mucosal membrane. Further, Ngirimbo consumers are at risk of developing dental caries, known to harbour microorganisms and development of infectious diseases. The control and regulation of Ngirimbo is highly recommended to maximise its capacity for use as a treatment/medication for tobacco replacement while minimising the negative impact on public health. Further work needs to be done to quantify the contents of Ngirimbo, and develop tolerance limits so that it may be used as a nicotine and tobacco replacement product.

Changing from telephone to videoconference for pre-treatment pharmacist consults in cancer services: Impacts to funding and time efficiency

Introduction: This study examined the reimbursement opportunity and the time efficiency of a standard care model of unscheduled telephone consults compared to scheduled videoconference consults for obtaining pre-treatment medication histories for patients with cancer. Methods: Data related to (a) the available and the claimed activity-based funding for both models and (b) the number of contacts and the duration of each contact to complete the patient’s medication history via either unscheduled telephone or scheduled videoconference consults were collected and compared. Results: Data was collected for 86 telephone and 56 videoconference consults. The actual activity-based funding claimed for telephone consults was $0, even though $86 of activity-based funding was available for each consult. This represented a $0 reimbursement for the staff time spent conducting the telephone consults, and a missed opportunity to claim $86 per consult. Activity-based funding was claimed for all but one videoconference consult with an average of $205 received per consult, when $221 per consult was available. Videoconference consults were an average of 2.3 min shorter than telephone consults. Discussion: When compared to unscheduled telephone consults, the scheduled videoconference consults represented increased reimbursement and equivalent time efficiency for the cancer pharmacist completing pre-treatment medication histories.

Prophylactic and Anaphylactic Approaches Towards COVID 19 in India – An Overview

Coronaviruses can cause a variety of disorders in the respiratory and gastrointestinal systems. Anything from a simple cold to something more serious like the Middle East Respiratory Syndrome (MERS-CoV) or SARS can induce breathing issues (SARS-CoV). The inquiry focused on COVID 19 symptoms, diagnosis, and treatment. Medication and immunizations were used to treat nCOV. Vaccines are currently being used all around the world to prevent disease. The approved vaccine candidates in India through September 2021 are listed on this work. These data are critical for future COVID 19 treatment reference and will be quite useful.

An adolescent with binge drinking

Alcohol use disorder (AUD) occurs in approximately 5% of adolescents. The diagnosis of AUD requires the presence of at least two signs or symptoms of problematic alcohol use. Adolescent AUD differs from adult AUD in several ways. Adolescents are more likely to engage in binge drinking rather than daily drinking. They are also less likely to experience tolerance or withdrawal and are more likely to engage in risk-taking behaviors related to substance use. All adolescents should be screened for alcohol and other substance use. A motivational interviewing approach should be used. Treatment includes individual and family therapy; parent involvement is an essential component of treatment. Medication options include naltrexone, acamprosate, and disulfiram.

Investigating the prevalence and risk of chemotherapy-induced neuropathy among cancer patients.

12078 Background: Neuropathy is a common side effect of some chemotherapies. Clinical and other factors may confer neuropathy risk, but rates and risk factors across neuropathy-causing chemotherapies are incompletely understood. Methods: We examined 15 chemotherapy drugs known to confer neuropathy. Within a broad population of cancer patients who underwent treatment with these agents at the University of Chicago Medicine between 2012-2018, we determined prevalence of chemotherapy-induced neuropathy, defined as patients with initiation of a neuropathy treatment medication (amitriptyline, carbamazepine, duloxetine, gabapentin, or pregabalin) after starting chemotherapy. We then analyzed chemotherapy-induced neuropathy risk for different drugs and based on clinical demographic factors. Results: We analyzed 7,866 patients (65.3% White, 53.7% Female, 27.6% Black/African-American, 5.6% Hispanic or Latino, 3.1% Asian/Mideast Indian, 2.4% More than one Race, 0.2% American Indian or Alaska Native, 0.2% Native Hawaiian/Other Pacific Islander). The overall prevalence of chemotherapy-induced neuropathy was 24.3% across our patient population. Black/African-American patients had an increased risk of chemotherapy-induced neuropathy compared to the rest of the patient cohort (OR 1.4, 95% CI 1.3-1.6, P = 1.6e-10). Females also exhibited an increased risk of chemotherapy-induced neuropathy compared to males (OR 1.2, 95% CI 1.1-1.3, P = 1.5e-3). Conclusions: Certain chemotherapy agents confer substantial risk of chemotherapy-induced neuropathy, and risk is increased in Blacks and females. Future work will investigate additional risk-modifying factors including the potential role of germline polymorphisms on chemotherapy neuropathy risk.[Table: see text]

Impact of guideline-based medical therapy on malignant arrhythmias and mortality among heart failure patients implanted with a primary prevention ICD/CRTD

Funding Acknowledgements Type of funding sources: None. Background In contrast with the well-established impact of heart failure (HF) medical treatment reducing HF hospitalizations and improving survival, its impact on ventricular arrhythmia (VA) is based mainly on circumstantial evidence. Aim To evaluate prevalence of HF medical treatment and its impact on VA and overall survival among HF patients implanted with primary prevention ICD/CRTD. Methods Single center retrospective analysis of all HF patients implanted with ICD/CRTD as primary prevention. Patients" indication for implant according to guidelines was confirmed by a senior EP physician. Thereafter, the association of HF medications and dose (% guideline recommended target dose) of beta-blockers (BB), Angiotensin-antagonists (AgA), Mineralocorticoid-antagonsits (MRA), and Anti-Arrhythmic Drugs (AAD) with VA episodes and overall mortality was analyzed, based on patients" medical records and device clinic regular interrogations. Results 186 HF patients qualifying for primary prevention ICD/CRTD implant according to HF and device guidelines, were included. Their mean ± SD age 66.4 ± 12 years, 15.1% female, 79 (42.5%) implanted with an ICD and 107 (57.5%) with CRTD. During 3.8 [2.1;6.7] (median[IQR]) years; 52 (28%) had VA and 77 (41.4%) died. Treatment (medication, % of patients) included: BB (83%), AgA (87%), MRA (59%), and AAD (43.5%). Doses were 25[12.5;50]% of target for BB or AgA and 25[0;50]% of target for MRA. Treatment with &gt;25% target dose of BB was associated with significantly reduced VA incidence. In a multivariable model including age, gender, diabetes, heart rate, and medication doses, increased BB dose was significantly and independently associated with reduced VA (HR 0.443 95%CI 0.222-0.885; p = 0.021). Kapkan-Myer analysis for survival without VA according to each medication group dose, supported reduced VA among patients receiving &gt; median dose of BB (Figure 1). Multivariable model for overall mortality including age, gender, renal disease, VA, and medical treatment; VA was associated with increased mortality (HR 2.672; 95% CI 1.429-4.999; p = 0.002) while AgA treatment was significantly and independently associated with reduced mortality (HR 0.515; 95% CI 0.285-0.929; p = 0.028). Conclusions In this cohort of real-life HF patients discharged after primary prevention ICD/CRTD implant, most of the patients were prescribed with guideline-based HF medications albeit with low doses. Higher BB dose was associated with reduced VA, while treatment with AgA was associated with improved survival. Abstract Figure. Survival without VA according to HF medi

Mab-Mig: Registry of the Spanish Neurological Society of Erenumab for Migraine Prevention. Three-Months Results

Background Erenumab was approved in Europe for migraine prevention in patients with ≥4 monthly migraine days (MMD). In Spain, Novartis started a personalized managed access program which allowed free access to erenumab before official reimbursement. The Headache Study Group of the Spanish Neurological Society started a registry to monitor real-world safety and efficacy, and all Spanish headache experts were invited to participate. Methods Patients fulfilled ICHD3 criteria for migraine and had ≥ 4MMD. Sociodemographic and clinical data were registered as well as MMD, headache frequency (MHD), prior and concomitant preventive treatment, medication overuse headache (MOH), migraine evolution, adverse events, and PROs: HIT6, MIDAS, and PGIC. A >50% reduction of MMD after 3 months was considered as response. Results We included 210 patients (female 86.7%, mean age 46.4 years old) from 22 hospitals from February 2019 – to – June 2020. Most patients (89.5%) suffered from chronic migraine with a mean evolution of 8.6 years. MOH was present in 70% of patients, and 17.1% had migraine with aura. Average of prior preventive treatment failure was >7 (BoNT/A had been used by 95.2%). Most patients (67,6%) started with erenumab 70mg. 61% of patients were also taking oral preventive drugs or getting simultaneous BoNT/A (27.6%). Responder rate was 37.1% and the mean reduction of MMD was -6.28 and MHD: -8.6. Regarding PROs: MIDAS: -35 p., HIT6: -11.6 p., PIGC: 4.7 p. Predictors of good response were: HIT6 score ( p =0.01), prior preventive treatment failures ( p =0.026), absence of MOH ( p =0.039), and simultaneous BoNT/A treatment ( p <0.001). 20% had adverse event, but only two of them were severe (0.9%) which led to treatment discontinuation. Mild constipation was the most frequent adverse event (8.1%). Conclusion In real-life, in a personalized managed access program, erenumab shows a good profile of efficacy and an excellent safety in migraine prevention in our cohort of refractory patients.

Impact of Guideline-Based Medical Therapy on Malignant Arrhythmias and Mortality among Heart Failure Patients Implanted with Cardioverter Defibrillator (ICD) or Cardiac Resynchronization-Defibrillator device (CRTD)

Aim: To evaluate prevalence of heart failure (HF) medical treatment and its impact on ventricular arrhythmia (VA) and survival among patients implanted with primary prevention ICD/CRTD. Methods and results: The association of treatment and dose (% guideline recommended target) of beta-blockers (BB), Angiotensin-antagonists (AngA), Mineralocorticoid-antagonsits (MRA), and Anti-Arrhythmic Drugs (AAD) after ICD/CRTD implant with VA episodes and mortality was analyzed. We included 186 patients, meanSD age 66.412 years, 15.1% female, 79(42.5%) implanted with an ICD and 107(57.5%) with CRTD. During 3.8 [2.1;6.7] (median[IQR]) years; 52(28%) had VA and 77(41.4%) died. Treatment (medication, % of patients) included: BB (83%), AngA (87%), MRA (59%), and AAD (43.5%). Median doses were 25[12.5;50]% of target for BB or AngA and 25[0;50]% of target for MRA. Treatment with >25% target dose of BB was associated with reduced incident VA. In a multivariable model including age, gender, diabetes, heart rate, and medication doses, increased BB dose was significantly and independently associated with reduced VA (HR 0.443 95%CI 0.222-0.885; p=0.021). On multivariable model for overall mortality including age, gender, renal disease, VA, and medical treatment; VA was associated with increased mortality (HR 2.672; 95% CI 1.429-4.999; p=0.002) and AngA treatment was significantly and independently associated with reduced mortality (HR 0.515; 95% CI 0.285-0.929; p=0.028). Conclusions: In this cohort of real-life HF patients discharged after ICD/CRTD implant, most of the patients were prescribed with guideline-based HF medications albeit with low doses. Higher BB dose was associated with reduced VA, while treatment with AngA was associated with improved survival.
