RESUMEN

INTRODUCTION: Asthma is a common condition affecting millions of children globally. The main goal of this study is to assess factors related to asthma management, particularly atopy level and the impact of genetic variants of the vitamin D receptor (VDR) gene. METHODS: Asthmatic children were enrolled in an outpatient respiratory clinic. Information on patients' medication adherence, medical and medication factors, and sociodemographic were gathered. Spirometry FEV1% and FVC% measurements, and the asthma control test were used to evaluate the severity of asthma, and genotyping of the VDR gene and radioallergosorbent test (RAST) were conducted. Regression analyses were conducted to evaluate variables associated with asthma control and spirometry measures. RESULTS: A total of 313 participants (67.4% males) were recruited in the current study. The mean age was 9.37 (±3.45) years. The mean score for adherence was 4.26 (±2.52), and only 46% of the participants had controlled asthma. Forward conditional stepwise binary regression showed that low and moderate Inhaled corticosteroids (ICS) dose (OR= 0.42 (95% CI 0.20-0.90), p = 0.026; OR = 0.371 (95% CI 0.2-0.72), p = 0.003, respectively) decreased the odds of being in the controlled asthma group, while higher inhaler score (OR = 2.75 (95% CI 2.17-3.49, p < 0.001)) increased the odds of being in the controlled asthma group. However, results found no association between VDR genotype and asthma control, spirometry values or hospitalization due to asthma. CONCLUSIONS: The results indicated that many of the asthma patients had poorly controlled asthma. Factors that were associated with poor asthma control included poor inhaler technique.

RESUMEN

INTRODUCTION: The integration of Artificial Intelligence (AI) in medical education and practice is a significant development. This study examined the Knowledge, Attitudes, and Practices (KAP) of health professions' students in Jordan concerning AI, providing insights into their preparedness and perceptions. METHODS: An online questionnaire was distributed to 483 Jordanian health professions' students via social media. Demographic data, AI-related KAP, and barriers were collected. Quantile regression models analyzed associations between variables and KAP scores. RESULTS: Moderate AI knowledge was observed among participants, with specific understanding of data requirements and barriers. Attitudes varied, combining skepticism about AI replacing human teachers with recognition of its value. While AI tools were used for specific tasks, broader integration in medical education and practice was limited. Barriers included lack of knowledge, access, time constraints, and curriculum gaps. CONCLUSIONS: This study highlights the need to enhance medical education with AI topics and address barriers. Students need to be better prepared for AI integration, in order to enable medical education to harness AI's potential for improved patient care and training.

RESUMEN

Morin (3,5,7,2',4'-pentahydroxyflavone; MR) is a bioactive plant polyphenol whose therapeutic efficacy is hindered by its poor biopharmaceutical properties. The purpose of this study was to develop a nanoparticle (NP) formulation to enhance the bioactivity and oral bioavailability of MR. The nanoprecipitation technique was employed to encapsulate MR in lipid-cored poly(lactide-co-glycolide) (PLGA) NPs. The optimal NPs were about 200 nm in size with an almost neutral surface charge and a loading efficiency of 82%. The NPs exhibited sustained release of MR within 24 h. In vitro antioxidant assays showed that MR encapsulation did not affect its antioxidant activity. On the other hand, anti-inflammatory assays in lipopolysaccharide-stimulated macrophages revealed a superior anti-inflammatory activity of MR NPs compared to free MR. Furthermore, oral administration of MR NPs to mice at a single dose of 20 mg/kg MR achieved a 5.6-fold enhancement in bioavailability and a prolongation of plasma half-life from 0.13 to 0.98 h. The results of this study present a promising NP formulation for MR which can enhance its oral bioavailability and bioactivity for the treatment of different diseases such as inflammation.

RESUMEN

Background: People perform sports for better health and wellbeing. However, the use of doping agents is emerging among young adults. This study investigated aspects related to doping agents. Methods: A reliable self-administered questionnaire (Cronbach's alpha =0.72, Pearson's r = 0.89) was used to assess knowledge, attitudes, and practicalities related to the use of doping agents. Results for pharmacists as health care providers (HCP, n=550) were compared with non-healthcare providers (Non-HCP, n=319). Results: Among pharmacists, 82.9% knew the definition of doping agents vs. 72.4% of non-HCP (P<0.001). However, 36.7% of pharmacists vs. 39.6% of non-HCP incorrectly classified doping agents (P=0.02). The majority of responders (89.8%) supported having an anti-doping authority, yet, only 15% were aware of the anti-doping organizations. The majority of responders (83%) did not receive an official education related to doping agents. Enhancing physical performance was perceived as a leading driver (82.1%) to use doping agents. More than 90% of responders supported awareness in the community. The perceived best tool for awareness was social media and TV sites, as suggested by pharmacists (95.0%) and non-HCP (92.1%, P=0.312). A total of 6.1% had ever used doping agents (3.6% pharmacist vs. 9.8% non-HCP, P<0.001). Almost half of the users utilized a diet or medication to counteract the side effects of doping agents. Within pharmacists, males received more requests to provide doping agents (41.9%) compared with females (23.8%, P<0.001). Conclusion: It is crucial to enhance professional and legal knowledge and public awareness about doping agents, not only for non-HCP but also for HCPs. Applying more restrictions on doping agents is strongly recommended.

RESUMEN

BACKGROUND: To assess antimicrobial prescribing in a Northern Ireland hospital (Antrim Area Hospital (AAH)) and compare them with those of a hospital in Jordan (Specialty Hospital). METHODS: Using the Global-PPS approach, the present study surveyed patients admitted to the hospital in 2015, the prescribed antibiotics, and a set of quality control indicators related to antibiotics. RESULTS: Ultimately, 444 and 112 inpatients in the AAH and the Specialty Hospital, respectively, were surveyed. For the medical group, 165 inpatients were prescribed 239 antibiotics in the AAH, while 44 patients in the Specialty Hospital were prescribed 65 antibiotics. In relation to the surgical group, 34 inpatients treated for infection were prescribed 66 antibiotics in the AAH, while 41 patients in the Specialty Hospital treated for infection were prescribed 56 antibiotics. For the medical patients, the most frequently prescribed antibiotics in the AAH were a combination of penicillins (18.8%) and penicillins with extended spectrum (18.8%). For the surgical patients, the most frequently prescribed antibiotics in the AAH were imidazole derivatives (24.2%). For the medical and surgical patients in the Specialty Hospital, the most frequently prescribed antibiotics were third-generation cephalosporins (26.2 and 37.5%, respectively). In medical patients, compliance to guidelines was 92.2% in the Specialty Hospital compared to 72.0% in the AAH (p < 0.001). In surgical patients, compliance to guidelines was 92.7% in the Specialty Hospital compared to 81.8% in the AAH (p = 0.012). CONCLUSIONS: The present study highlighted differences in the utilisation of antimicrobials between two hospitals in two distinct regions and benchmarked antibiotic prescriptions across two hospitals.

RESUMEN

(1) Background: First aid administered during road accidents can save millions of lives. However, the knowledge and attitudes of the Jordanian population towards first aid are lacking. This study aimed to examine the knowledge, attitudes, and barriers to performing first aid among the Jordanian population during road accidents. (2) Methods: An online questionnaire was developed and distributed using various Jordanian social media platforms. The questionnaire collected the participants' sociodemographic details and assessed their first aid knowledge, attitudes toward first aid, and barriers preventing the participants from performing first aid in emergencies. (3) Results: 732 participants participated in this study. The median knowledge score regarding first aid items was 9 (7-10) out of the maximum possible score of 15. The median first aid attitude score was 24 (22-27) out of a maximum possible score of 30. The most commonly reported barrier to performing first aid among the participants was "lack of first aid training" (76.78%), followed by "lack of knowledge about first aid" (75.81%) and "fear of performing first aid" (57.51%). The participants with lower income levels exhibited more negative attitudes towards first aid (4). Conclusions: This study underscores the urgent need for enhanced first aid training and awareness in Jordan. The participants' first-aid knowledge overall was limited, although positive attitudes toward first-aid delivery were observed. The findings emphasize the need for regular and structured first-aid training courses, addressing barriers such as fear and misinformation and ensuring accessibility across all socioeconomic levels to improve preparedness for road traffic accidents and other emergencies. This comprehensive approach can better equip the Jordanian population to effectively manage emergencies and improve public health outcomes.

RESUMEN

Purpose: Asthma is a major chronic disease of all ages, globally. Exacerbations are a significant problem for asthmatic patients. Despite advances in asthma management and efforts to identify asthma triggers, viral infections of the respiratory tract remain the most frequent triggers of asthma exacerbations. This study explored knowledge, attitudes, and practices (KAP) of asthmatic patients towards receiving the influenza vaccine. Patients and Methods: This cross-sectional study enrolled 397 adult asthmatic patients visiting the outpatient respiratory clinics of three Jordanian medical facilities. Results: The research included 66.4% females, with a median age of 32 years. The results showed that 42.4% of enrolled asthmatics had never received the flu vaccine and only 51.1% reported that they intended to take the vaccine in the current year. Most of those who had been vaccinated at least once in their lifetime reported that the side effects were mild (61.8%). Variables that decreased refusal/hesitancy towards receiving the flu vaccine in the current year included having well-controlled asthma (RRR = 0.193, 95% Cl (0.053-0.698), p =0.012), and high knowledge about asthma and flu (RRR= 0.916, 95% Cl (0.847-0.990), p =0.028, respectively). Conclusion: A small number of the participants adhered to vaccinating against the flu which is due to lack of knowledge about the asthma, flu, and the vaccine. To address this challenge, we propose targeted health education campaigns, collaboration with healthcare providers, and utilization of digital platforms.

RESUMEN

The human microbiome encodes more than three million genes, outnumbering human genes by more than 100 times, while microbial cells in the human microbiota outnumber human cells by 10 times. Thus, the human microbiota and related microbiome constitute a vast source for identifying disease biomarkers and therapeutic drug targets. Herein, we review the evidence backing the exploitation of the human microbiome for identifying diagnostic biomarkers for human disease. We describe the importance of the human microbiome in health and disease and detail the use of the human microbiome and microbiota metabolites as potential diagnostic biomarkers for multiple diseases, including cancer, as well as inflammatory, neurological, and metabolic diseases. Thus, the human microbiota has enormous potential to pave the road for a new era in biomarker research for diagnostic and therapeutic purposes. The scientific community needs to collaborate to overcome current challenges in microbiome research concerning the lack of standardization of research methods and the lack of understanding of causal relationships between microbiota and human disease.

RESUMEN

SARS-CoV-2 (COVID-19) vaccines are critical for containing serious infections. However, as COVID-19 evolves toward more transmissible varieties and serum antibody levels in vaccinated persons steadily decline over time, the likelihood of breakthrough infections increases. This is a cross-sectional study based on an online questionnaire for Jordanian adults (n = 915) to determine how individuals who have finished the current vaccination regimen feel about a prospective COVID-19 booster shot and what factors might influence their decision. Almost half of the participants (44.6%) intended to get the booster dose of the COVID-19 vaccine. The most frequently mentioned reasons for participants' reluctance to get the COVID-19 vaccine booster dose were "The benefits of booster dose have not been scientifically proven" (39.8%), followed by "I took the last dose a short time ago, and there will be no need to take the booster dose for at least a year" (24.6%). In turn, "I was infected with COVID-19; thus, I do not require the booster dose" was the least reported reason (13.1%). These findings highlight the considerable hesitancy toward COVID-19 booster immunization among Jordanians, as well as the variables associated with vaccine hesitancy and the most frequently mentioned reasons for hesitancy, which will aid in creating excellent campaigns regarding booster doses.

RESUMEN

Medication Adherence Report Scale questionnaire (MARS-5) and the Beliefs about Medication Questionnaire-specific (BMQ-specific) are well known tools to assess adherence to medication and beliefs of chronic patients. However, validated Arabic versions of such questionnaires are lacking. We aim to validate the Arabic versions of BMQ-specific and MARS-5. In this study, a cross-sectional study was performed between November 2019 and March 2020. Participants were reached from secondary and tertiary care clinics in Jordan. Exploratory factor analysis (EFA) and Confirmatory Factor analysis (CFA) were conducted to validate the employed questionnaires on the tested sample. The internal consistency of the questionnaires was assessed by calculating Cronbach's alpha, and Cronbach's alpha if item is deleted. A total of 485 patients who met the inclusion criteria were recruited. The mean age of the participants was 57.14 years (22-82 years); and 39% of the participants were older than 65 years. The most common chronic diseases reported by participants were hypertension and diabetes mellitus, 35.7 and 32.2% respectively. EFA suggested two-factor model for BMQ-specific and one-factor model for MARS-5 which was confirmed by CFA analyses. The resulted Cronbach's alphas of the questionnaires ranged from 0.89-0.93. Both analyses showed that the Arabic versions of both MARS-5 and BMQ-specific are valid and can be used for the suggested study population. Further validation-based research may enhance the transcultural adaptation of such questionnaires.

RESUMEN

Alzheimer's disease (AD) is a polygenic multifactorial neurodegenerative disease that, after decades of research and development, is still without a cure. There are some symptomatic treatments to manage the psychological symptoms but none of these drugs can halt disease progression. Additionally, over the last few years, many anti-AD drugs failed in late stages of clinical trials and many hypotheses surfaced to explain these failures, including the lack of clear understanding of disease pathways and processes. Recently, different epigenetic factors have been implicated in AD pathogenesis; thus, they could serve as promising AD diagnostic biomarkers. Additionally, network biology approaches have been suggested as effective tools to study AD on the systems level and discover multi-target-directed ligands as novel treatments for AD. Herein, we provide a comprehensive review on Alzheimer's disease pathophysiology to provide a better understanding of disease pathogenesis hypotheses and decipher the role of genetic and epigenetic factors in disease development and progression. We also provide an overview of disease biomarkers and drug targets and suggest network biology approaches as new tools for identifying novel biomarkers and drugs. We also posit that the application of machine learning and artificial intelligence to mining Alzheimer's disease multi-omics data will facilitate drug and biomarker discovery efforts and lead to effective individualized anti-Alzheimer treatments.

RESUMEN

The question of whether children should be vaccinated against COVID-19 is currently being argued. The risk-benefit analysis of the vaccine in children has been more challenging because of the low prevalence of acute COVID-19 in children and the lack of confidence in the relative effects of the vaccine and the disease. One of the most convincing arguments for vaccinating healthy children is to protect them from long-term consequences. The aim of this study was to assess Jordanian parents' intention to vaccinate their children. This is an Internet-based cross-sectional survey. The researchers prepared a Google Forms survey and shared the link with a number of Jordanian Facebook generic groups. Data were gathered between September and November 2021. In this study, convenience sampling was used. Knowledge about COVID-19 and preventive practices against COVID-19 were calculated for each participant. A total of 819 participants completed the survey (female = 70.9%). Of these, 274 (30.2%) participants intended to vaccinate their children, whereas the rest were either unsure 176 (21.5%) or intended not to vaccinate their children 396 (48.4%). The variables that increased the odds of answering "No" vs "Yes" to "will you vaccinate your children against COVID-19" included not willing to take the vaccines themselves (OR 3.75; CI, 1.46-9.62) and low protective practice group (OR 1.73;CI, 1.12-2.68). Participants had significant levels of refusal/hesitancy. Several barriers to vaccination were identified; attempts to overcome these should be stepped up.

RESUMEN

OBJECTIVE: Cost-effectiveness analyses that consider all currently used antiemetics in the case of emetogenic chemotherapy-induced nausea and vomiting (CINV) have not been performed yet. We aim to compare the cost-effectiveness of olanzapine (OLA), or/and neurokinin-1 receptor antagonists (NK-1-RAs), in combination with palonosetron (PAL) and dexamethasone (DEX) in preventing highly emetogenic CINV. METHODS: Two decision analytic models were constructed. The first model was based on overall complete response (CR); the second model was based on rate of absence of nausea. Four antiemetic regimens PAL + DEX, NK-1-RAs + PAL + DEX, OLA + PAL + DEX, and PAL + NK-1-RA + DEX + OLA were compared in terms of cost, overall CR and rate of absence of nausea. Base case incremental cost-effectiveness ratio (ICER) estimates were calculated. The study was from the US payer perspective. RESULTS: In terms of CR, the PAL + NK-1-RA + DEX + OLA was associated with the highest gains in the percentage of CR among all treatment regimens at base case ICERs of $4220 versus PAL + DEX, $4656 versus NK-1-RA + PAL + DEX, $16,471 versus OLA + PAL + DEX. In term of rate of absence of nausea, the PAL + NK-1-RA + DEX + OLA was associated with the highest rate of absence of nausea among all the treatment regimens at base case ICERs of $2291 versus PAL + DEX, $1304 versus NK-1-RA + PAL + DEX, $2657 versus OLA + PAL + DEX. CONCLUSION: from an economic perspective, our study revealed that whether to use overall CR or/and rate of absence of nausea as determinants in the antiemetic decision for the CINV patients, the CR-based-, and rate of absence of nausea-based cost-effectiveness analyses, showed negotiable ICER estimates for the treatment PAL + NK-1-RA + DEX + OLA over the combinations PAL + DEX, NK-1-RA + PAL + DEX, and OLA + PAL + DEX regimens.

RESUMEN

Introduction: Adherence to medications is very crucial for an optimized clinical outcome in the management of chronic diseases. Beliefs about medications and other factors can significantly affect adherence to chronic medications. The objective of the present research was to identify the associated factors of adherence to medication in Jordanian patients with chronic diseases utilizing a stepwise binary logistical regression model. Methods: A cross-sectional study was carried out between November 2018 and March 2020. The participants were reached from secondary and tertiary care setting clinics in Jordan. The recruited patients were asked to report their attitudes of adherence to medications and beliefs about medications via filling out the MARS-5 and BMQ-specific tools. Sociodemographic data were also collected from the recruited patients and included in the regression model. A stepwise binary logistical regression model was applied to identify the associated factors of adherence to chronic medications in the tested sample. Results: A total of 485 patients who met the inclusion criteria were recruited. The mean age of the participants was 57.14 (age ranged from 22 to 82 years). Around 39% of the participants were older than 65 years. Most of the patients were either hypertensive or diabetic (35.7% and 32.2%, respectively). The logistic regression model indicated that necessity beliefs are strongly associated with adherence (OR 4.22), while concerns beliefs, dosage frequency and having medical insurance were negatively associated with adherence (OR 0.73, 0.74 and 0.26, respectively), with a p-value ≤ 0.05. Conclusions: Both the MARS-5 and BMQ-specific questionnaires were applied successfully on the tested sample. Better attention should be paid to the logistic regression model variables that were associated with adherence in order to guarantee optimal treatment outcomes in the treatment of chronic diseases.

RESUMEN

Lactate dehydrogenase (LDH) is a key enzyme in the last step of glycolysis, playing a role in the pyruvate-to-lactate reaction. It is associated with the prognosis and metastasis of many cancers, including breast cancer. In this study, we investigated the changes in LDH gene expression and lactate concentrations in the culture media during tamoxifen resistance development in the MCF-7 cell line, and examined LDHB promoter methylation levels. An upregulation of 2.9 times of LDHB gene expression was observed around the IC50 concentration of tamoxifen in treated cells, while fluctuation in LDHA gene expression levels was found. Furthermore, morphological changes in the cell shape accompanied the changes in gene expression. Bisulfate treatment followed by sequencing of the LDHB promoter was performed to track any change in methylation levels; hypomethylation of CpG areas was found, suggesting that gene expression upregulation could be due to methylation level changes. Changes in LDHA and LDHB gene expression were correlated with the increase in lactate concentration in the culture media of treated MCF-7 cells.

RESUMEN

OBJECTIVES: The aim of this study was to explore the trend of ischemic heart disease (IHD) admission and the prescriptions of IHD medications in England and Wales. METHODS: A secular trends study was conducted during the period of 1999 to 2019. We extracted hospital admission data for patients from all age groups from the Hospital Episode Statistics database in England and the Patient Episode Database for Wales. Prescriptions of IHD medications were extracted from the Prescription Cost Analysis database from 2004 to 2019. The chi-squared test was used to assess the difference between the admission rates and the difference between IHD medication prescription rates. The trends in IHD-related hospital admission and IHD-related medication prescription were assessed using a Poisson model. The correlation between hospital admissions for IHD and its IHD medication-related prescriptions was assessed using the Pearson correlation coefficient. RESULTS: Our study detected a significant increase in the rate of cardiovascular disease (CVD) medication prescriptions in England and Wales, representing a rise in the CVD medications prescription rate of 41.8% (from 539,334.95 (95% CI = 539,286.30-539,383.59) in 2004 to 764,584.55 (95% CI = 764,545.55-764,623.56) in 2019 prescriptions per 100,000 persons), with a mean increase of 2.8% per year during the past 15 years. This increase was connected with a reduction in the IHD hospital admission rate by 15.4% (from 838.50 (95% CI = 836.05-840.94) in 2004 to 709.78 (95% CI = 707.65-711.92) in 2019 per 100,000 persons, trend test, p < 0.01), with a mean decrease of 1.02% per year during the past 15 years and by 5% (from 747.43 (95% CI = 745.09-749.77) in 1999 to 709.78 (95% CI = 707.65-711.92) in 2019 per 100,000 persons, trend test, p < 0.01) with a mean decrease of 0.25% per year during the past two decades in England and Wales. CONCLUSION: The rate of hospitalisation due to IHD has decreased in England and Wales during the past two decades. Hospitalisation due to IHD was strongly and negatively correlated with the increase in the rates of dispensing of IHD-related medications. Other factors contributing to this decline could be the increase in controlling IHD risk factors during the past few years. Future studies exploring other risk factors that are associated with IHD hospitalisation are warranted.

RESUMEN

BACKGROUND: Hypoxic condition induces molecular alterations which affect the survival rate and chemo-resistant phenotype of cancer cells. OBJECTIVE: The aim of this study is to investigate the influence of intermittent hypoxic conditions on the expression of glucose metabolism genes in breast cancer MCF7 cell line. METHODS: The gene expression was analyzed using a polymerase chain reaction-array method. In addition, the cell resistance, survival and migration rates were examined to assure the hypoxic influence on the cells. RESULTS: 30 hypoxic episodes induced the Warburg effect through significant (p-value < 0.05) upregulation of the expression of PCK2, PHKG1, ALDOC, G6PC, GYS2, ALDOB, HK3, PKLR, PGK2, PDK2, ACO1 and H6PD genes that are involved in glycolysis, were obtained. Furthermore, the expression of the major gluconeogenesis enzyme genes was significantly (ANOVA, p-value < 0.05) downregulated. These molecular alterations were associated with increased MCF7 cell division and migration rate. However, molecular and phenotypic changes induced after 30 episodes were normalized in MCF7 cells exposed to 60 hypoxic episodes. CONCLUSION: It is concluded, from this study, that 30 intermitted hypoxic episodes increased the survival rate of MCF7 breast cancer cells and induced the Warburg effect through upregulation of the expression of genes involved in the glycolysis pathway. These results may increase our understanding of the molecular alterations of breast cancer cells under hypoxic conditions.

RESUMEN

Alfuzosin is a medication approved by the US Food and Drug Administration to treat benign prostatic hyperplasia symptoms. Bioequivalence studies are demanded by regulatory authorities to evaluate the expected in vivo biological similarity of 2 formulations of a medication. The aim of this study is to assess the bioavailability of the generic (test) and branded (reference) formulations of 10-mg alfuzosin extended-release tablets after oral administration to healthy adults under fed conditions. The study used a comparative randomized, single-dose, 2-way crossover open-label study design. Thirty-three participants were recruited and completed the clinical assessment. The pharmacokinetic parameters maximum plasma concentration (Cmax ), area under the plasma concentration-time curve (AUC0-t ), AUC extrapolated to infinity (AUC0-∞ ), time to maximum concentration, and elimination half-life were estimated to prove bioequivalence. The confidence intervals for the log-transformed test/reference ratios for alfuzosin 110.7% (98.0-124.9) and 112.0% (101.9-123.1) for Cmax and AUC0-t respectively, which are within the allowed limits specified by the regulatory authorities (80-125% for Cmax and AUC0-t ). The test formulation can therefore be prescribed as an alternative to the reference for symptomatic treatment of benign prostatic hyperplasia.

RESUMEN

Dalfampridine is a medication that is approved by the US Food and Drug Administration to improve walking impairments in patients with multiple sclerosis (MS). The branded dalfampridine is enormously expensive; hence, the availability of generic dalfampridine will provide better access to the medication, especially for uninsured patients with MS. Bioequivalence studies are demanded by the regulatory authorities to allow the marketing of new generics of dalfampridine. The aim of this study was to assess the bioavailability of the generic (test) and branded (reference) formulations of 10 mg dalfampridine of extended-release tablets after oral administration to healthy adults under fed conditions. The current report methodology was based on a comparative, randomized, single-dose, 2-way crossover open-label study design. Twenty-seven subjects were given a single dose of the test dalfampridine tablet and completed the clinical study. The pharmacokinetic parameters Cmax and AUC0→t, Kel , AUC0→∞ , tmax , and t1/2el were estimated to prove bioequivalence. The confidence intervals for the log-transformed test/reference ratios for dalfampridine 100.96% (97.09%-104.97%) and 99.77% (95.81%-103.87%) for Cmax and AUC0→∞ , respectively, were within the allowed limit specified by the regulatory authorities (80%-125%). Hence, clinically, the test tablet can be prescribed as an alternative to the reference for the indication of improving walking impairments in patients with MS.

RESUMEN

BACKGROUND: Newspapers are considered one of the most viewed and influential media sources in both the United Kingdom and United States. However, information about how newspapers portray health care apps to the readers has been lacking. OBJECTIVE: This study investigated the reporting on health care apps in newspapers published in the United Kingdom and United States. METHODS: The Nexis UK database was used to identify and select relevant articles. Systematic content analysis of the articles that met the inclusion criteria (articles of any format that contained reference to health care apps or medical apps) within the highest circulated newspapers in the United Kingdom and United States over a period of 10 years (2006-2015) was conducted. Interrater reliability of coding was established using a 10% sample of the chosen articles. RESULTS: A total of 220 (151 UK and 69 US) relevant newspaper articles were retrieved. Health care apps were most frequently reported on in the Daily Mail and The Guardian (UK newspapers) and in the New York Times and the Washington Post (US newspapers). An exponential rise in published scientific articles (PubMed) on health care-related apps was noted during the study period. A total of 26.4% (58/220) and 19.1% (42/220) of the retrieved newspaper articles appeared in the features and main news sections, respectively. General information about health care apps was the main theme coved by the newspapers (45.9%, 101/220). Most of the articles represented a societal point of view (72.3%, 159/220). The main focus of the articles was on general health matters (48.2%, 106/220) and specific disease matters (36.8%, 81/220). Diabetes was the most frequently mentioned disease in the articles. A high proportion (91.4%, 201/220) of the articles mentioned benefits of using health care apps mainly for personalized care, whereas 24.1% (53/220) of the articles commented on related risks such as anxiety and confidentiality issues. Almost half (45.9%, 101/220) of the articles mentioned potential facilitators to the use of apps; less than 10% (16/220) discussed barriers. Most of the articles (83.6%, 184/220) were judged as having balanced judgment on the present topic and more than half (60.0%, 132/220) of the articles were judged to be of generally low quality. CONCLUSIONS: Health care apps were not widely reported in newspaper articles in the United Kingdom and United States over the study period; however, there appeared to be much more recent interest. Characteristically, the articles focused more frequently on societal impact and on general health rather than on disease-specific apps.
