Cultivo e uso racional de plantas medicinais e fitoterápicos / Cultivation and rational use of medicinal and herbal plants / Cultivo y uso racional de plantas medicinales y herbáceas

A utilização de plantas medicinais como alternativa terapêutica vem atingindo um público cada vez maior. Assim, os fitoterápicos podem atuar como forma opcional de terapêutica levando em consideração o menor custo, e cujos benefícios se somam aos da terapia convencional. Com isso, o objetivo deste trabalho foi enfatizar a importância do cultivo e do uso racional de medicamentos fitoterápicos e plantas medicinais. Para tanto, foram incluídos artigos em português e inglês inseridos no banco de dados: Scielo, Google acadêmico, além de revistas eletrônicas, livros com embasamento científico de referência e base de dados do Ministério da Saúde entre os anos de 2018 a 2022. As plantas medicinais e os medicamentos fitoterápicos podem provocar efeitos adversos, interferir no efeito de medicamentos utilizados concomitantemente, além da possibilidade de causar intoxicações pela presença de contaminantes em produtos de baixa qualidade. Para a produção de bioativos, em níveis quali e quantitativamente adequados, o cultivo das plantas medicinais deve ser cuidadosamente realizado, através de técnicas adequadas para preservação do solo e plantio são essenciais, como a utilização de adubos verdes e a cobertura vegetal, que além de protegerem o solo da radiação solar, prevenir a evaporação excessiva da água e melhorar as características físicas, químicas e biológicas do sol. Esses critérios influenciam a qualidade do fitoterápico, portanto a fim de garantir a eficácia terapêutica, as plantas devem ser corretamente cultivadas, coletadas, identificadas e conservadas. Sendo assim, conclui-se que a utilização de plantas medicinais para tratamentos tem sido cada vez mais indicada pelos profissionais da saúde, ressaltando a importância do uso seguro e racional, com alerta para as suas consequências.

The use of medicinal plants as a therapeutic alternative has been reaching a growing public. Thus, herbal medicines can act as an optional form of therapy taking into account the lowest cost, and whose benefits are added to those of conventional therapy. Thus, the objective of this work was to emphasize the importance of the cultivation and rational use of herbal medicines and medicinal plants. To this end, articles in Portuguese and English inserted in the database: Scielo, Google academic, in addition to electronic journals, books with scientific reference base and database of the Ministry of Health between the years 2018 to 2022 were included. herbal medicines can cause adverse effects, interfere with the effect of medicines used concomitantly, in addition to the possibility of causing poisoning due to the presence of contaminants in low-quality products. For the production of bioactives, at qualitatively and quantitatively appropriate levels, the cultivation of medicinal plants must be carefully carried out, through techniques cultivated for soil preservation and planting are essential, such as the use of green manures and vegetation cover, which in addition to protect the soil from solar radiation, prevent excessive water evaporation and improve the physical, chemical and biological characteristics of the sun. These criteria influence the quality of the herbal medicine, therefore, in order to guarantee therapeutic efficacy, as the plants must be correctly cultivated, collected, identified and conserved. Therefore, it is concluded that the use of medicinal plants for treatments has been increasingly indicated by health professionals, emphasizing the importance of safe and rational use, with an alert to its consequences.

Iron salt supplementation during gestation and gestational diabetes mellitus

ABSTRACT OBJETIVE To evaluate the association between the use of iron salts during the first two trimesters of gestation in non-anemic women and the development of gestational diabetes mellitus. METHODS The study used maternal data from the 2015 Pelotas Birth Cohort. All non-anemic women at the 24th week of gestation (n = 2,463) were eligible for this study. Gestational diabetes mellitus was self-reported by women. Crude and adjusted logistic regression were performed considering level of significance = 0.05. RESULTS Among the women studied, 69.7% were exposed to prophylactic iron supplementation in the first two trimesters of gestation. The prevalence of gestational diabetes mellitus among those exposed was 8.7% (95%CI: 7.4-10.1) and 9.3% (95%CI: 7.4-11.6) among those who were not exposed. Iron supplementation was not associated with increased risk of gestational diabetes mellitus in crude (OR = 0.9; 95%CI: 0,7-1,3) and adjusted analysis (OR = 1.1; 95%CI :0,8-1,6). CONCLUSIONS The results suggest that routine iron use in non-anemic pregnant women does not increase the risk of developing gestational diabetes. This evidence supports the existing national and international guidelines, in which prophylactic iron supplementation is recommended for all pregnant women as soon as they initiate antenatal care in order to prevent iron deficiency anemia.

Estudantes de medicina e medicamentos: melhoramentos e outros usos / Medical students and medicines: improvements and other uses

A presente pesquisa tem por objeto as percepções de estudantes de medicina de uma instituição de ensino superior (IES) privada do interior do Estado do RJ em torno de substâncias ditas de uso para performance. Neste trabalho, elas são entendidas como substâncias, prescritas ou não, utilizadas para o propósito de melhorar alguma função cognitiva ou de humor. Investigamos como as ideias, valores, formação profissional em curso e condições materiais de acesso a medicamentos e outras substâncias colaboram na formação de práticas de uso de medicamentos (prescritos ou não), suplementos e/ou vitaminas por estudantes de medicina. A metodologia de pesquisa utilizada contou com dois procedimentos: 1) a aplicação de um questionário online para mapear os consumos terapêuticos de performance pelos estudantes; 2) entrevistas semiestruturadas em profundidade com estudantes que se voluntariaram a falar sobre suas experiências de uso. Como resultados encontrados, destacam-se práticas de uso de substâncias acionadas pelos estudantes de acordo com suas necessidades acadêmicas ou de vida

This research assumes aims to analyze the perceptions of medical students from a private higher education institution, located in the interior of the State of Rio de Janeiro (RJ), regarding substances used for performance. In this study, they are understood as substances, prescribed or not, used for the purpose of improving some cognitive function or mood. We investigated how ideas, values, ongoing professional training, and material conditions of access to medicines and other substances collaborate in the formation of practices for the use of medicines (prescribed or not), supplements and/or vitamins by medical students. The research methodology adopted was composed of two procedures: 1) the application of an online questionnaire to map the therapeutic consumption of performance by the students; 2) semi-structured interviews with students, who voluntarily talked about their experiences of use. Among the results found, there are practices of substance use triggered by students according to their academic or life needs.

Estimating the Theoretical Cost Implications of Funding New Drugs Considered Not to Be Cost-Effective.

This study aims to estimate the theoretical excess expenditure that would be incurred by the Irish state-payer, should drugs be reimbursed at their original asking ("list") price rather than at a price at which the drug is considered cost-effective. In Ireland, all new drugs are evaluated by the National Centre for Pharmacoeconomics. For this study, drugs that were submitted by pharmaceutical companies from 2012 to 2017 and considered not cost-effective at list price were reviewed. A total of 43 such drugs met our inclusion criteria, and their pharmacoeconomic evaluations were further assessed. The price at which the drug could be considered cost-effective (cost-effective price) at the upper cost-effectiveness threshold used in Ireland (€ 45 000/quality adjusted life-year) was estimated for 18 drugs with an available cost-effectiveness model. Then, for each drug, the list price and cost-effective price (both per unit) were both individually applied to 1 year of national real-world drug utilization data. This allowed the estimation of the expected expenditures under the assumptions of list price paid and cost-effective price paid. The resulting theoretical excess expenditure, the expenditure at list price minus the expenditure at the cost-effective price, was estimated to be €108.2 million. This estimate is theoretical because of the confidentiality of actual drug prices. The estimation is calculated using the list price and likely overestimates the actual excess expenditure, which would reduce to zero if cost-effective prices are agreed. Nevertheless, this estimate illustrates the importance of a process to assess the value of new drugs so that potential excess drug expenditure is identified.

Factors associated with the appropriate use of ultra-broad spectrum antibiotics, meropenem, for suspected healthcare-associated pneumonia.

ABSTRACT: Pneumonia is a common disease-causing hospitalization. When a healthcare-associated infection is suspected, antibiotics that provide coverage for multi-drug resistant (MDR) or extended-spectrum beta-lactamase (ESBL) bacteria are frequently prescribed. Limited data is available for guidance on using meropenem as a first-line empiric antimicrobial in hospitalized patients with risk factors for MDR/ESBL bacterial infections.This was a single-center, retrospective study designed and conducted to identify factors associated with positive cultures for MDR/ESBL pathogens in hospitalized patients with suspected healthcare-associated pneumonia.Of the 246 patients, 103 patients (41%) received meropenem. Among patients prescribed meropenem, MDR/ESBL pathogens were detected in only 20 patients (13%). Patients admitted from a skilled nursing facility/long-term acute care (SNF/LTAC) or with a history of a positive culture for MDR/ESBL pathogens were significantly associated with positive cultures of MDR/ESBL pathogens during the hospitalization (odds ratio [95% confidence intervals], 31.40 [5.20-189.6] in SNF/LTAC and 18.50 [2.98-115.1] in history of culture-positive MDR/ESBL pathogen). There was no significant difference in mortality between the 3 antibiotic groups.Admission from a SNF/LTAC or having a history of cultures positive for MDR/ESBL pathogens were significantly associated with a positive culture for MDR/ESBL pathogens during the subsequent admission. We did not detect significant association between meropenem use as a first-line drug and morbidity and mortality for patients admitted to the hospital with suspected healthcare-associated pneumonia, and further prospective studies with larger sample size are needed to confirm our findings.

Medicine reviews: do they reduce benzodiazepine use in older Australians?

OBJECTIVES: Medicine reviews are an opportunity to identify and address inappropriate prescribing. The aim of this study was to explore changes in benzodiazepine use among older Australians following a medicine review. STUDY TYPE: Retrospective observational cohort study using linked administrative data. METHODS: We used Medicare Benefits Schedule and Pharmaceutical Benefits Scheme claims from a random 10% sample of Medicare beneficiaries. We identified people aged 65 years or older who received a medicine review in 2013-14 and were using benzodiazepines at the time of review. We identified a propensity score matched comparison cohort of those using benzodiazepines who did not receive a review. Two outcome measures were used: any benzodiazepine use and changes to the quantity of benzodiazepines dispensed (diazepam equivalents) from baseline to 90 and 180 days following a medicine review. RESULTS: We identified 4002 people using benzodiazepines on the day of their medicine review, of whom approximately one-third discontinued benzodiazepines within 90 days (29.7%) and 180 days (36.4%;) after the review. We observed a similar discontinuation rate in the comparison group (32.6%, p = 0.006; and 38.0%, p = 0.12, respectively). In people who were dispensed lower quantities of benzodiazepines (less than 250 mg of diazepam equivalents in the 90 days before the medicine review), we found that 50.3% ceased using benzodiazepines or used lower quantities (measured as diazepam equivalents) following the medicine review (28.7% and 19.7% respectively). We also observed a reduction in the quantities used in people where initial exposure was high (3.4% ceased; 59.4% decreased). We observed a similar change in volume within the matched comparison group. CONCLUSIONS: Medicine reviews are not associated with any additional reduction in benzodiazepine use among older adults, up to 180 days after review, beyond what was observed in the general population.

Drug utilization study and cost analysis of adult ß-thalassemia major patient therapy at Dr. Soetomo General Hospital Surabaya.

OBJECTIVES: The main therapy of ß-thalassemia major are blood transfusion and iron chelation drugs. However, those therapies also have some adverse effects and problems such as iron overload, transfusion reactions, nutritional deficiencies, and patient compliance problems. Those arising problems also have an impact on therapy cost. Hence, this study was designed to analyze drug utilization study and cost of therapy in ß-thalassemia major adult patients at Dr. Soetomo General Hospital Surabaya. METHODS: This research was conducted in descriptive observational-retrospective design using secondary data obtained from patient's medical records and billing registrations from January 1-December 31, 2019. RESULTS: There were 18 patients out of 233 patients that were analyzed. Deferasirox was the most administered drug with doses between 500 mg/day-1,500 mg/day while deferiprone was ranged between 1,500 and 4,500 mg/day. Patients also received transfusion reaction drugs with dexamethasone injection 5 mg/ml which was administered the most. The most administered supplement was folic acid 1 mg. Patients had an increase in serum ferritin due to low compliance. Deferasirox had the most adherence number of patients with decrease of serum ferritin. The two highest costs of direct medical components were top-up medicines and consumable medical supplies. Overall, the hospital gained profit from national health insurance claims. CONCLUSIONS: The most administered chelating agent was deferasirox. Deferasirox also had the most adherence number of patients with decreased number of serum ferritin. However, deferasirox also yielded the highest cost. Yet, overall, the hospital gained profit from national health insurance claims.

Impact of mass and systematic antibiotic administration on antibiotic resistance in low- and middle-income countries? A systematic review.

Antibiotic consumption is a key driver of antimicrobial resistance (AR), particularly in low- and middle-income countries (LMICs) where risk factors for AR emergence and spread are prevalent. However, the potential contribution of mass drug administration (MDA) and systematic drug administration (SDA) of antibiotics to AR spread is unknown. We conducted a systematic review to provide an overview of MDA/SDA in LMICs, including indications, antibiotics used and, if investigated, levels of AR over time. This systematic review is reported in accordance with the PRISMA statement. Of 2438 identified articles, 63 were reviewed: indications for MDA/SDA were various, and targeted populations were particularly vulnerable, including pregnant women, children, human immunodeficiency virus (HIV)-infected populations, and communities in outbreak settings. Available data suggest that MDA/SDA may lead to a significant increase in AR, especially following azithromycin administration. However, only 40% of studies evaluated AR. Integrative approaches that evaluate AR in addition to clinical outcomes are needed to understand the consequences of MDA/SDA implementation, combined with standardised AR surveillance for timely detection of AR emergence.

Prevalence and Predictors of Multivitamin Supplement Use After Stroke in Ghana.

BACKGROUND: Multivitamins are commonly used supplements in high income countries, but their net benefit-risk, remains inconclusive. Little is known about the prevalence and predictors of multivitamin supplementation among individual with chronic illnesses in sub-Saharan Africa, especially stroke. PURPOSE: To assess the frequency and factors associated with of use of multivitamin supplement among stroke survivors in Ghana. METHODS: We analyzed prospectively collected data on consecutively encountered stroke survivors seen at an out-patient clinic in Ghana between January 2018 and March 2020. We collected baseline demographic and clinical details, and use of multivitamins among other secondary prevention medications prescribed. We assessed factors associated with multivitamin supplementation using a multivariable logistic regression analysis. RESULTS: Among 1,101 stroke survivors, 324 (29.4%) were on multivitamin supplements. Factors independently associated with multivitamin use were being divorced (OR 2.88; 95% CI: 1.52-5.47), time since diagnosis of index per each month increase (OR 0.99; 95% CI: 0.99-1.00), and number of prescribed classes of antihypertensive medications (OR 0.81; 95% CI: 0.72-0.92). CONCLUSION: Nearly a third of stroke survivors in this Ghanaian sample were on multivitamin supplementation, with select socio-clinical factors being linked to this practice. Future studies should examine how/if this practice is interfering with optimal stroke outcomes.

Attitudes towards and use of cannabis in New Zealand patients with inflammatory bowel disease: an exploratory study.

AIMS: We aimed to assess the use of and attitudes towards cannabis use (medicinal and recreational) by people with IBD in New Zealand. METHODS: People with IBD were invited to complete an anonymous online questionnaire. Participants were recruited via postal mail using a hospital database of patients with IBD (developed by the Gas-troenterology Department at Dunedin Public Hospital) and via online recruitment (advertised on the Crohn's and Colitis New Zealand website, Facebook page and e-mail list). Inclusion criteria were ages 18+ and self-reported confirmed IBD diagnosis. RESULTS: In total, 378 participants completed the questionnaire, with 334 eligible responses. Partici-pants were predominantly New Zealand European (84%) and female (71%). Sixty-one percent of re-spondents had CD and 34% UC. Overall, 51% of respondents reported having ever used cannabis. Of those, 63% reported use as recreational and 31% for reduction of IBD symptoms. Users were more likely to be younger (on average by 6.4 years), with on-going symptoms, unemployed or self-employed and current or ex-smokers. There were no differences by disease status or severity. Symp-toms most reported as improved by cannabis use were abdominal pain/cramping, nausea/vomiting and loss of appetite. Fifty-four percent of participants reported that if cannabis were legal, they would request it for medicinal use to help manage their symptoms. CONCLUSIONS: Overall, our research aligns with previous observational research that reports im-provements in symptoms of IBD with cannabis use. Studies of a higher evidence level (eg, RCTs) would be needed to guide prescribing. In the meantime, this research provides useful background to clini-cians about patients' views and experiences.

Characterization of individuals with osteoarthritis in the United States and their use of prescription and over-the-counter supplements.

PURPOSE: Osteoarthritis (OA) is a frequently occurring, chronic condition; however, few studies describe the clinical characteristics of individuals with OA and the treatments they use to manage their symptoms. We conducted a study to characterize the OA population in the US and describe the nonsurgical management used by this population based on consumer research data collected through an online survey. METHODS: Data from the 2017 US National Health and Wellness Survey (NHWS) for adults aged ≥35 years were used to evaluate the relationship between OA and certain study participant characteristics and to identify the most commonly used treatment options. NHWS data were collected through a survey of individuals drawn from the internet panel maintained by Lightspeed Research (Bridgewater, New Jersey) and its panel partners. Weighted estimates were generated using data from the 2016 Current Population Survey (Annual Demographics File) of the US Census Bureau. Comparisons between the general and OA populations were made based on body mass index (BMI), exercise frequency, and comorbid diagnoses of hypertension or diabetes. Among the OA population, the use of dietary supplements, prescription or over-the-counter (OTC) treatments with chondroitin with or without glucosamine (Ch ± Gl), prescription treatment by time since OA diagnosis, and utilization of a physical therapist were also recorded. RESULTS: The prevalence of OA in the overall population was 17.6 % and was higher for individuals with a BMI ≥ 25 (21.9 %), patients diagnosed with hypertension or diabetes (36.2 %), and those who did not exercise regularly (19.0 %). Adults without OA were more likely to exercise regularly (12 days per month or more) than adults diagnosed with OA. Ch ± Gl (6.0 %) was the most commonly used OTC dietary supplement in the OA population, followed by omega-3 fatty acids (2.8 %), vitamin D (1.9 %), calcium (1.1 %), and multivitamins (0.7 %). Individuals using Ch ± Gl were more likely to use OTC only products (75.4 % vs 37.3 %) or prescription medications, namely non-steroidal anti-inflammatory drugs (NSAIDs) and/or opioids, and OTC products (24.6 % vs 13.0 %) compared with individuals not using Ch ± Gl, while individuals not using Ch ± Gl were more likely to be untreated (30.3 % vs 0) or to use prescription medications only (19.4 % vs 0). Nearly 32 % of individuals with OA reported using prescription treatments, and the likelihood of using a prescription treatment increased with number of years since OA diagnosis (<3 years: 27.5 %; ≥21 years: 32.5 %). The pharmaceutical products used by this population primarily consisted of nonsteroidal anti-inflammatory drugs, acetaminophen and opioids. Approximately 13 % of patients with OA had visited a physical therapist in the past 6 months. CONCLUSIONS: The prevalence of OA was higher in those with a high BMI, and comorbid diabetes or hypertension. Individuals with OA using Ch ± Gl primarily reported use of OTC products only or used them in combination with prescription products. The likelihood of using prescription products increased with the length of OA history. These data provide valuable new information about demographics, clinical characteristics, and commonly used prescription and OTC treatments and dietary supplements in the OA population.

Comparative associations between anticholinergic burden and emergency department visits for anticholinergic adverse events in older Korean adults: a nested case-control study using national claims data for validation of a novel country-specific scale.

BACKGROUND: Considering the limited generalizability of previous anticholinergic burden scales, the Korean Anticholinergic Burden Scale (KABS) as a scale specific to the Korean population was developed. We aimed to validate the KABS by detecting the associations between high anticholinergic burden, measured with the KABS, and emergency department (ED) visits compared to the pre-existing validated scales in older Korean adults. METHODS: A nested case-control study was conducted using national claims data. The cases included the first anticholinergic ED visits between July 1 and December 31, 2016. Anticholinergic ED visits were defined as ED visits with a primary diagnosis of constipation, delirium, dizziness, fall, fracture, or urinary retention. Propensity score-matched controls were identified. Average daily AB scores during 30 days before the index date were measured. Multivariate logistic regression analyses were performed. RESULTS: In total, 461,034 were included. The highest proportion of those with high AB was identified with KABS (5.0%). Compared with those who had a KABS score of 0, older adults with a score ≥ 3 were at higher risk for overall anticholinergic ED visits (aOR, 1.62, 95% CI, 1.53-1.72), as well as visits for falls/fractures (aOR: 1.54, 95% CI: 1.40-1.69), dizziness (aOR: 1.44, 95% CI: 1.30-1.59), delirium (aOR: 2.96, 95% CI: 2.28-3.83), constipation (aOR: 1.84, 95% CI: 1.68-2.02), and urinary retention (aOR: 2.13, 95% CI: 1.79-2.55). High AB by KABS showed a stronger association with overall anticholinergic ED visits and visits due to delirium and urinary retention than those by other scales. CONCLUSIONS: In conclusion, KABS is superior to pre-existing scales in identifying patients with high AB and predicting high AB-related ED visits in older Korean adults.

Prescribers' compliance with summary of product characteristics of dabigatran, rivaroxaban and apixaban-A European comparative drug utilization study.

Despite a tremendous increase of direct oral anticoagulants (DOACs) prescriptions in recent years, only few data is available analysing prescribers' adherence to Summary of Product Characteristics (SmPC). We aimed to assess adherence to registered indications, contraindications, special warnings/precautions, and potential drug-drug interactions for three DOAC compounds (dabigatran, rivaroxaban, and apixaban) in six databases of five European countries (The Netherlands, United Kingdom, Spain, Denmark, and Germany). We included adult patients (≥18 years) initiating DOACs between 2008 and 2015. For several SmPC items, broad definitions were used due to ambiguous SmPC terms or lacking data in some databases. Within the study period, a DOAC was initiated in 407 576 patients (rivaroxaban: 240 985 (59.1%), dabigatran: 95 303 (23.4%), and apixaban: 71 288 (17.5%)). In 2015, non-valvular atrial fibrillation was the most common indication (>60% in most databases). For the whole study period, a substantial variation between the databases was found regarding the proportion of patients with at least one contraindication (inter-database range [IDR]: 8.2%-55.7%), with at least one special warning/precaution (IDR: 35.8%-75.2%) and with at least one potential drug-drug interaction (IDR: 22.4%-54.1%). In 2015, the most frequent contraindication was "malignant neoplasm" (IDR: 0.7%-21.3%) whereas the most frequent special warning/precaution was "prescribing to the elderly" (≥75 years; IDR: 25.0%-66.4%). The most common single compound class interaction was "concomitant use of non-steroidal anti-inflammatory drugs" (IDR: 3.0%-25.3%). Contraindications, special warnings/precautions, and potential drug-drug interactions were present in a relevant number of new DOAC users. Due to broad definitions used for some SmPC terms, overall proportions for contraindications are prone to overestimation. However, for unambiguous SmPC terms documented in the databases sufficiently, the respective estimates can be considered valid. Differences between databases might be related to "true" differences in prescription behaviour, but could also be partially due to differences in database characteristics.

Children with Heterozygous Familial Hypercholesterolemia in the United States: Data from the Cascade Screening for Awareness and Detection-FH Registry.

OBJECTIVE: To describe enrollment characteristics of youth in the Cascade Screening for Awareness and Detection of FH Registry. STUDY DESIGN: This is a cross-sectional analysis of 493 participants aged <18 years with heterozygous familial hypercholesterolemia recruited from US lipid clinics (n = 20) between April 1, 2014, and January 12, 2018. At enrollment, some were new patients and some were already in care. Clinical characteristics are described, including lipid levels and lipid-lowering treatments. RESULTS: Mean age at diagnosis was 9.4 (4.0) years; 47% female, 68% white and 12% Hispanic. Average (SD) highest Low-density lipoprotein cholesterol (LDL-C) was 238 (61) mg/dL before treatment. Lipid-lowering therapy was used by 64% of participants; 56% were treated with statin. LDL-C declined 84 mg/dL (33%) among those treated with lipid-lowering therapy; statins produced the greatest decline, 100 mg/dL (39% reduction). At enrollment, 39% had reached an LDL-C goal, either <130 mg/dL or ≥50% decrease from pre-treatment; 20% of those on lipid-lowering therapy reached both goals. CONCLUSIONS: Among youth enrolled in the Cascade Screening for Awareness and Detection of FH Registry, diagnosis occurred relatively late, only 77% of children eligible for lipid-lowering therapy were receiving treatment, and only 39% of those treated met their LDL-C goal. Opportunities exist for earlier diagnosis, broader use of lipid-lowering therapy, and greater reduction of LDL-C levels.

Calcium daily intake and the efficacy of a training intervention on optimizing calcium supplementation therapy: A clinical audit.

BACKGROUND AND AIMS: Calcium is an essential element for human health, with key roles in the prevention and therapy of multifactorial conditions. Calcium dietary intake is often insufficient in the general population. The aim of this study was to perform a clinical audit for general practitioners (GPs) to understand the efficacy of training intervention on doctors' awareness about dietary calcium and supplements. METHODS AND RESULTS: General practice outpatients were enrolled (Before Clinical Audit, BCA) from the same sanitary district, and calcium dietary intake was evaluated with a validated questionnaire, also collecting information about the consumption of calcium and vitamin D supplements. Then, a training intervention with a frontal lesson and discussion with GPs involved was performed. After one month of this intervention, a second outpatient enrolment was performed (Post Clinical Audit, PCA) in the same general practices to evaluate differences in nutritional suggestions and supplement prescription by GPs. In BCA, the calcium dietary intake was low, with nobody reaching 1000 mg as suggested by the guidelines. Only 6.6% and 24.5% took calcium and vitamin D supplements, respectively; in the PCA, these percentages increased to 28% and 78% for calcium and vitamin D supplements, respectively (p < 0.01 PCA vs BCA). There were no differences in calcium dietary intake between BCA and PCA. CONCLUSION: Training intervention on GPs was successful to sensitize them regarding calcium intake problems; GPs tended to increase the prescription of supplements but not to suggest changes in dietary habits.

The impact of pulse oximetry and Integrated Management of Childhood Illness (IMCI) training on antibiotic prescribing practices in rural Malawi: A mixed-methods study.

BACKGROUND: The misdiagnosis of non-malarial fever in sub-Saharan Africa has contributed to the significant burden of pediatric pneumonia and the inappropriate use of antibiotics in this region. This study aims to assess the impact of 1) portable pulse oximeters and 2) Integrated Management of Childhood Illness (IMCI) continued education training on the diagnosis and treatment of non-malarial fever amongst pediatric patients being treated by the Global AIDS Interfaith Alliance (GAIA) in rural Malawi. METHODS: This study involved a logbook review to compare treatment patterns between five GAIA mobile clinics in Mulanje, Malawi during April-June 2019. An intervention study design was employed with four study groups: 1) 2016 control, 2) 2019 control, 3) IMCI-only, and 4) IMCI and pulse oximeter. A total of 3,504 patient logbook records were included based on these inclusion criteria: age under five years, febrile, malaria-negative, and treated during the dry season. A qualitative questionnaire was distributed to the participating GAIA providers. Fisher's Exact Testing and odds ratios were calculated to compare the prescriptive practices between each study group and reported with 95% confidence intervals. RESULTS: The pre- and post-exam scores for the providers who participated in the IMCI training showed an increase in content knowledge and understanding (p<0.001). The antibiotic prescription rates in each study group were 75% (2016 control), 85% (2019 control), 84% (IMCI only), and 42% (IMCI + pulse oximeter) (p<0.001). An increase in pneumonia diagnoses was detected for patients who received pulse oximeter evaluation with an oxygen saturation <95% (p<0.001). No significant changes in antibiotic prescribing practices were detected in the IMCI-only group (p>0.001). However, provider responses to the qualitative questionnaires indicated alternative benefits of the training including improved illness classification and increased provider confidence. CONCLUSION: Clinics that implemented both the IMCI course and pulse oximeters exhibited a significant decrease in antibiotic prescription rates, thus highlighting the potential of this tool in combatting antibiotic overconsumption in low-resource settings. Enhanced detection of hypoxia in pediatric patients was regarded by clinicians as helpful for identifying pneumonia cases. GAIA staff appreciated the IMCI continued education training, however it did not appear to significantly impact antibiotic prescription rates and/or pneumonia diagnosis.

[Strategies to reduce antibiotic use with the help of complementary and integrative medicine]. / Stratégies de réduction de l'usage d'antibiotiques à l'aide de la médecine complémentaire et intégrative.

Limiting antibiotic use is urgent due to increasing antibiotic resistance and the long-term implications of a disturbed microbiome. Data on antibiotic use of physicians integrating conventional and complementary medicine show that a significant reduction of antibiotic use in primary care is possible. In the setting of non-complicated infections in out-patient medicine, open dialogue with the patient, recognizing the importance of fever and reducing antipyretic use are general measures that can help reduce patients' concerns, and increase their trust in a well-functioning immune system and a treatment approach without antibiotics. Accumulating evidence suggests that complementary medicine strategies are useful in the management of common infections without antibiotics.

Vu l'augmentation de la résistance aux antibiotiques et les conséquences qu'implique, à long terme, un microbiote perturbé, il est urgent de limiter leur consommation. Les données obtenues chez les médecins intégrant médecines conventionnelle et complémentaire montrent un recours aux antibiotiques diminué dans les soins primaires. Une communication adaptée, la compréhension de l'importance de la fièvre et la diminution de la prise d'antipyrétiques sont autant d'étapes clés pouvant aider les patients à surmonter leurs craintes, à renforcer leur confiance en leur système immunitaire et en un traitement sans antibiotiques en cas d'infections simples. Un nombre croissant d'études démontre ainsi que les outils de la médecine complémentaire peuvent contribuer à la gestion des infections courantes sans antibiotiques.

The association between hydroxyurea adherence and opioid utilization among Texas Medicaid enrollees with sickle cell disease.

BACKGROUND: Individuals with sickle cell disease (SCD) suffer from recurrent catastrophic pain crises that are often managed by opioid analgesics. Being adherent to hydroxyurea has been associated with decreased health care resource use for pain; however, evidence of its association with opioid use is limited. OBJECTIVE: To determine if adherence to hydroxyurea is associated with opioid use among patients with SCD. METHODS: This retrospective study used Texas Medicaid data from September 1, 2011, to August 31, 2016 (study period). The index date was the date of hydroxyurea initiation. Patients who were aged 2-63 years at the index date, had ≥ 1 inpatient or ≥ 2 outpatient SCD diagnoses during the study period, had ≥ 1 hydroxyurea prescription during the identification period (September 1, 2011-August 31, 2015), had no diagnosis of other indications for hydroxyurea during the study period, and were continuously enrolled for at least 12 months after the index date were included. Hydroxyurea adherence was measured using medication possession ratio (MPR). The study outcomes (measured 1-year post-index) were (a) opioid use; (b) number of opioid prescriptions; (c) strong opioid use (morphine, hydromorphone, fentanyl, and methadone); (d) number of strong opioid prescriptions; (e) high-dose opioid use (≥ 50 mg morphine milligram equivalent [MME]); and (f) days supply for opioid prescriptions. Covariates included demographic (age and gender) and clinical (vaso-occlusive crisis [VOC], avascular necrosis, iron overload, acute chest syndrome, and blood transfusion) characteristics. Descriptive, bivariate (chi-square and Wilcoxon-Mann-Whitney tests), multiple logistic regression, and negative binomial regression analyses were performed. RESULTS: 1,146 patients (18.3 [12.3] years) met the inclusion criteria. Of these, 19.6% were adherent to hydroxyurea (defined as MPR ≥ 80%) and mean (SD) MPR was 48.3% (29.7%). In the 1 year following hydroxyurea initiation, 923 (80.5%) patients had ≥ 1 opioid prescription with 7.6 (9.4) opioid prescriptions per patient, while 259 (22.6%) patients had ≥ 1 strong opioid prescription with 1.5 (4.4) strong opioid prescriptions per patient. Average (SD) opioid dose was 41.7 (74.3) mg MME, and 27.1% had high daily MME doses (≥ 50 mg MME). Average (SD) opioid days supply was 83.1 (112.2) days. After adjusting for covariates, compared with being nonadherent, being adherent to hydroxyurea was associated with a 50.5% decreased risk of having strong opioids (OR = 0.495, 95% CI = 0.278-0.879, P = 0.0165). Additionally, SCD-related complications (VOC, avascular necrosis, and iron overload) and older age were significant factors associated with opioid use and higher MME. Post hoc analyses showed that being adherent to hydroxyurea was significantly associated with lower probabilities of experiencing SCD-related complications. CONCLUSIONS: Results showed that patients with SCD are moderately adherent to hydroxyurea. Being adherent to hydroxyurea was found to be associated with a lower risk of receiving a prescription for strong opioids. Findings suggest that close monitoring and interventions to improve adherence may help mitigate strong opioid use among these patients.
