Evaluation of the Association between Inhaler technique and Adherence in Asthma Control: Cross-Sectional Comparative Analysis Study between Amman and Baghdad

Purpose: Asthma is a chronic condition affecting millions of people all around the world. Asthma has no cure, but disease control is essential and highly recommended. However, the available tools for asthma control assessment don’t include factors such as inhaler technique and adherence. This study aimed to assess the correlation between inhaler techniques, adherence, and level of asthma control in two different healthcare settings; Jordan and Iraq. Patients and methods: A cross-sectional observational study was con-ducted over six months, from January to August 2018, in two public hospitals in Amman (Jordan) and Baghdad (Iraq). Asthmatic patients were interviewed to assess their inhaler technique, adherence, and asthma control. The researcher personally visited both public hospitals, conducting face-to-face interviews with patients at the hospital outpatient clinics. Validated questionnaires were used for patient assessment, including demographics, asthma history and medication use, the patient’s inhaler technique, adherence, and asthma control. Results: A total of 300 patients entered the study, with a mean age of 45.54 ± 13.71. The asthma control test showed very poor asthma control for patients living in both countries (Amman n=78 (52.0%) vs. Baghdad n=106 (70.0%)). An asthma knowledge assessment showed that most asthmatic patients in both countries didn’t follow their asthma medication plan (Amman n=78 (52.0%) vs. Baghdad n=93 (62.0%). Conclusion: In both Jordan and Iraq, asthma patients were found to be poorly controlled. Knowledge of patients was inadequate, probably leading to the poorly managed chronic disease. The results of this study highlight the significance of the pharmacist’s role in recognizing asthmatic patients requiring assistance. Furthermore, they underscore the pharmacist’s pivotal contribution to delivering patient education and counseling, ultimately resulting in enhanced asthma control. (AU)

Video-based teach-to-goal intervention on inhaler technique on adults with asthma and COPD: A randomized controlled trial.

BACKGROUND: Incorrect use of inhalers is a problem associated with poor patient outcomes. Despite improvement in the technique after verbal educations, this deteriorates over-time requiring re-enforcement through different educative strategies. This study aimed to assess the impact of a novel video-based teach-to-goal (TTG) educational intervention on: mastery of inhaler technique, disease control, medication adherence and disease-related quality of life (QoL) over-time among asthma and COPD patients. METHODS: This prospective, open-label, randomized controlled trial was registered in ClinicalTrials.gov: Identifier NCT05664347. After baseline assessment participants received either a verbal (control group) or a video-based (intervention group) TTG strategy. After 3-month the intervention was assessed for impact on the intended outcomes. Inhaler technique was assessed using standardized checklists, disease control using the Asthma control test and COPD assessment test respectively for asthma and COPD patients while adherence using the Morisky Green Levine scale. For QoL, the mini asthma quality of life questionnaire and the St. George respiratory questionnaire were used for asthmatic and COPD patients, respectively. Differences in outcomes between intervention-control groups were analyzed using either Chi-Square (X2)/Fisher Exact or Mann Whitney test. The impact of intervention on outcomes over-time was examined using either McNemar or Wilcoxon test. RESULTS: At baseline, intervention (n = 51) and control (n = 52) groups had comparable demographic/clinical characteristics. At follow-up, inhaler technique improved among intervention group compared to control group (93.4% vs 67%) and to baseline (93.4% to 49.5%), (P<0.05). Similarly, medication adherence ameliorated among the intervention group in comparison to control group (88.2% to 61.5%) and to baseline (88.2% to 66.7%), (P<0.05). In regards to disease control, results showed an amelioration among the intervention group compared to baseline (35.3% to 54.9%) (P<0.05). QoL scores improved significantly among asthma patients (intervention group) at follow-up vs baseline. Better scores were also observed for COPD patients compared to controls, (P<0.05). CONCLUSION: Video-based (TTG) was effective in enhancing inhaler technique over time as well as improving disease control, medication adherence, and QoL.

Real-World Effectiveness of Four Types of COVID-19 Vaccines.

BACKGROUND: There is a scarcity of evidence regarding the real-world effectiveness of coronavirus disease 2019 (COVID-19) vaccines. This was the first study to evaluate the effectiveness of four types of vaccines against asymptomatic and symptomatic infection, and COVID-19 outcomes among the general population. METHODS: This was a matched comparison group quasi-experimental study conducted in Jordan between 1 January and 29 August 2021. In the first part of the study, 1200 fully vaccinated individuals were matched with 1200 unvaccinated control participants. In order to measure vaccine effectiveness, the infection rates of both vaccinated and unvaccinated groups were calculated. The second part of the study included measuring specific anti-SARS CoV-2 immune cells and antibodies. RESULTS: BNT162b2 (Pfizer, New York, NY, USA) showed a significantly higher effectiveness against asymptomatic COVID-19 infection (91.7%) and hospitalization (99.5%) than BBIBP-CorV (Sinopharm, Beijing, China) (88.4% and 98.7%, respectively) and ChAdOx1 nCoV-19 (AstraZeneca, Cambridge, UK) (84.3%, and 98.9%, respectively). The effectiveness rates of the Sputnik V (Gamaleya Research Institute, Moscow, Russia) vaccine against asymptomatic, symptomatic, and hospitalization were 100%, 100%, and 66.7%, respectively. The highest median anti-spike (S) IgG values were seen in individuals who received BNT162b2 (2.9 AU/mL) and ChAdOx1 nCoV-19 (2.8 AU/mL) vaccines. The levels of anti-S IgG were significantly decreased after 7 months of vaccination with BNT162b2 and BBIBP-CorV. There were significant decreases in the median number of neutralizing antibodies one month and seven months after receiving BNT162b2 (from 88.5 to 75.2 4 Bioequivalent Allergen Unit per milliliter/mL), BBIBP-CorV (from 69.5 to 51.5 BAU/mL), and ChAdOx1 nCoV-19 (from 69.2 to 58.BAU/mL) vaccines. The highest percentage of T cells specific to COVID-19 vaccine was found in individuals who received BNT162b2 (88.5%). CONCLUSION: All four vaccines evaluated in this study showed effectiveness against asymptomatic COVID-19 infection, symptomatic infection, hospitalization, and death. Furthermore, BNT162b2, BBIBP-CorV, and ChAdOx1 nCoV-19 induced high levels of immunology markers within one month of vaccination.

Assessing Anxiety and Depression Among Students Post-COVID-19: Exploring Associating Factors.

Background: The COVID-19 pandemic has had a large impact on global mental health including anxiety and depression rates, many factors affected the vulnerability to these psychological conditions amongst university students. Aim: To explore the level of anxiety and depression of university students living in Jordan. Methods: A cross-sectional study design was conducted in which an electronic survey was created and distributed, university students residing in Jordan participated in the study. Results: A total of 1241 students were enrolled in the study. The mean anxiety score among males and females was (9.68 (SD = 4.10)) and (10.46 (SD = 4.14)), respectively. 42.1% of males had "abnormal" anxiety score compared to 48.4% females. The mean depression score among males (7.77 (SD = 4.31)) was similar to that for the females (7.64 (SD = 4.14)), and 26.0% of the males had "abnormal" depression score compared to 22.6% of the females. Factors affecting anxiety scores included younger age, being a female, taking medication/s, or drinking two cups of coffee or more a day. Conclusion: With 46% and 24% of students suffering from abnormal anxiety and depression respectively, it is important for education policy makers to take immediate measures to allocate students in need of psychological assessment and help to deliver suitable interventions.

Assessing adherence to medications: Is there a difference between a subjective method and an objective method, or between using them concurrently?

Background: Patients’ adherence to medication can be assessed by several subjective or objective methods. The Global Initiative for Asthma (GINA) has recommended the use of both measures simultaneously. Objective: To assess patients’ adherence to medication using a subjective or an objective method separately, and via using a combination of both methods. As well as identifying the degree of agreement between the two methods. Methods: Participants who met the study inclusion criteria completed the Adherence to Asthma Medication Questionnaire (AAMQ). A retrospective audit was conducted in order to extract pharmacy refill records for the previous twelve months. The patients’ pharmacy refill records were expressed using the Medication Possession Ratio (MPR). Data were analyzed using the Statistical Package for Social Science. The degree of agreement was determined by Cohen’s kappa coefficient (κ). Results: In terms of the difference in the ability of each method to identify non-adherent patients, a higher percentage of non-adherent patients were identified using the self-reported AAMQ (61.4%) compared to the pharmacy refill records (34.3%). When both methods, in combination, were used to assess adherence, the percentage of non-adherent patients was 80.0%, which is higher than each method when used separately. Twenty percent of the patients were considered adherent on both assessment methods, while 15.7% were considered non-adherent via both methods. Consequently, the AAMQ and pharmacy refill records agreed on 35.7% of the patients. The degree of agreement analysis showed a low correlation between the two methods. Conclusion: The combination strategy resulted in a higher percentage of non-adherent patients, compared to using a subjective (the AAMQ) or an objective (the pharmacy refill records) method. The GINA guideline proposition may be supported by the present study’s findings. (AU)

Development and validation of the Adherence to Asthma Medication Questionnaire (AAMQ).

Background: Adherence to medication is the cornerstone to achieve the best treatment outcome. Pharmacists are healthcare professionals found in a pivotal position to assess asthmatic patients' adherence to medication. A brief, reliable, and valid measure of patients adherence to mediations is useful to enable the pharmacists to deliver that vital service. Objective: To develop a reliable and valid adherence assessment tool for asthmatic patients. Methods: The Adherence to Asthma Medication Questionnaire (AAMQ-13) was developed based on an extensive literature review, followed by applying the Delphi technique, and then it was pilot-tested by 55 patients. The final AAMQ-13 was completed by 213 patients. Psychometric evaluation was assessed including reliability, criterion validity, and construct validity. Results: The AAMQ-13 is a feasible 13-item questionnaire, as it can be completed within an average of two minutes. It has high reliability (Cronbach's alpha= 0.87). Criterion-concurrent validity was established by comparing the AAMQ-13 to the Test of the Adherence to Inhaler (TAI) and the pharmacy refill records. Criterion-convergent validity was established by comparing the AAMQ-13 to the Asthma Control Test (ACT) questionnaire and the Positive Health Behaviors Scale (PHBS). Construct validity was established through AAMQ-13 factor analysis which revealed two factors explaining 51.76% of the total variance. Conclusion: The AAMQ-13 is a reliable and valid questionnaire with several desirable characteristics as it has high reliability, good criterion validity, and strong construct validity. The AAMQ-13 is a suitable questionnaire that can identify non-adherent patients and reveal the reasons behind their non-adherence : Asthma; Adherence to medication; Compliance; Questionnaire; Self-report; Scale; Survey.

Active Safety Surveillance of Four Types of COVID-19 Vaccines: A National Study from Jordan.

BACKGROUND: Although the Pfizer-BioNTech (BNT162b2), Oxford-AstraZeneca (ChAdOx1 nCoV-19), Sinopharm (BBIBP-CorV), and Sputnik V coronavirus disease 2019 (COVID-19) vaccines have been granted emergency approval in many nations, their safety has never been studied and compared in one community-based study. This study aimed to investigate and compare the incidence, nature, severity, and predictors of adverse events following immunization (AEFIs) with COVID-19 vaccines. METHOD: This was a prospective observational study conducted in Jordan between 1 January and 21 September 2021. A team of pharmacists and nurses (n = 407) collected the local and systemic AEFIs of four COVID-19 vaccines by prospectively contacting participants registered in the national vaccination program platform. A red-flag technology was inserted to classify and track rare and serious AEFIs. RESULTS: This study included 658,428 participants who were vaccinated with 1,032,430 doses; 610,591, 279,606, 140,843, and 1390 participants received the first and second doses of the BNT162b2, BBIBP-CorV, ChAdOx1 nCoV-19, and Sputnik V vaccines, respectively. The overall incidence of AEFIs was 28.8%, and the overall rates of systemic, local, and immediate hypersensitivity AEFIs were 22.2%, 18.8%, and 0.5%, respectively. The highest proportions of immediate hypersensitivity AEFIs and systemic AEFIs were reported after administration of the Sputnik V vaccine and ChAdOx1 nCoV-19 first dose, respectively. The most severe AEFIs were reported after ChAdOx1 nCoV-19 first dose and BNT162b2 second dose. The hospitalization and mortality rates after vaccination were 20 in 10,000 and 1 in 10,000, respectively. Based on red-flag tracking, the top three outcome events were lymphadenopathy (157.9/100,000), anxiety disorders (136.6/100,000), and lower respiratory tract infection (100.9/100,000), with Guillain-Barré syndrome (1.8/100,000), vasculitis (3.0/100,000), and myopericarditis (4.8/100,000) being the least common. CONCLUSION: The incidence rates of local, systemic, and immediate hypersensitivity AEFIs of four COVID-19 vaccines occur frequently. High incidence rates of rare and serious AEFIs were reported in this study. Younger participants, females, those who had previously had COVID-19, and smokers were more likely to encounter AEFIs.

Hospital unit costs in Jordan: insights from a country facing competing health demands and striving for universal health coverage.

BACKGROUND: Public providers in Jordan are facing increasing health demands due to human crises. This study aimed to benchmark the unit costs of hospital services in public providers in Jordan to provide insights into the outlook for public health care costs. METHODS: The unit costs of hospital services per admission, inpatient days, outpatient visits, emergency visits and surgical operations were estimated using the standard average costing method (top-down) for the fiscal year 2018-2019. The unit costs per inpatient day were estimated for nine specialities and staff in Jordanian dinars (exchange rate JOD 1 = USD 1.41). RESULTS: The average unit cost per admission in Jordan was JOD 782.300 (USD 1101.80), the per inpatient day cost was JOD 236.600 (USD 333.20), the per bed day cost was JOD 172.900 (USD 244.90), the per outpatient visit cost was JOD 58.400 (USD 82.30), the per operation cost was JOD 449.600 (USD 633.20) and the per emergency room visit cost was JOD 31.800 (USD 44.80). The specialities of ICU/CCU and OB/GYN presented the highest unit costs per inpatient day across providers: JOD 377.800 (USD 532.90) and JOD 362.600 (USD 510.70), respectively. The average salaried unit cost of staff depended mainly on year of employment. Nonetheless, the unit costs varied depending on the service utilization, type of service and organizational outlet. CONCLUSIONS: Knowledge of how unit costs vary across public providers in Jordan is essential to outline cost control strategies and inform future research. Institutionalization of the cost information system and high-level governmental support are necessary to generate a routine practice of collecting and sharing cost information.

Pharmacists-physicians collaborative intervention to reduce vaccine hesitancy and resistance: A randomized controlled trial.

PURPOSE: Given their negative influence on community health, vaccine hesitancy and resistance are emerging challenges that require healthcare intervention. Therefore, this study aimed to assess the impact of physician-pharmacist collaborative health coaching on rates of hesitancy and resistance for a COVID-19 vaccine. METHODS: After an initial assessment of rates of hesitancy and resistance for a COVID-19 vaccine was conducted, hesitant and resistant participants were approached, recruited, and randomized into an active and control group. Pharmacists-physicians collaborative coaching intervention was delivered to active group subjects over two months through Facebook live sessions. The outcome measures were assessed in both groups before coaching, directly after coaching, and a month after coaching. RESULTS: The proportions of hesitancy and resistance for a COVID-19 vaccine among subjects in the active group were significantly reduced from 64.3% and 35.7% before coaching to 20.1% and 7.8% directly after coaching, respectively. These proportions were further reduced to 11.1% and 3.3% a month after coaching, respectively. Furthermore, the mean scores for knowledge on, and attitude towards COVID-19 vaccine were significantly increased from 4.6 ± 1.8 and 4.1 ± 1.7 before coaching to 7.5 ± 3.1 and 8.9 ± 3.8 directly after coaching, respectively. However, the change in mean score of beliefs about COVID-19 vaccines among active group subjects was not significant. CONCLUSION: High rates of hesitancy and resistance for a COVID-19 vaccine were found in Jordan. These rates can be significantly reduced through online pharmacists-physicians collaborative coaching, which can also improve knowledge of and attitude towards COVID-19 vaccines.

A three-phase population based sero-epidemiological study: Assessing the trend in prevalence of SARS-CoV-2 during COVID-19 pandemic in Jordan.

The evolution of the COVID-19 pandemic in Jordan during the first 10 months of the epidemic was peculiar and can be easily categorized in three different phases: a first period featuring a very low number of reported cases, a second period with exponential growth from August with up to 8000 cases on the 18th November 2020, and a third phase with steady and progressive decline of the epidemiological curve. With the aim of better determine the entity of the population exposed to SARS-CoV-2, the Jordan Ministry of Health with the support of the WHO launched three rounds of the nationwide sero-prevalence survey. Using population proportionate to size (PPS) methodology, around 5000 individuals were selected from all Jordan governorates. Blood samples were collected from all participants and ELISA assays for total IgM, IgG antibodies to COVID-19 were used for testing at the National Public Health Laboratory. Results revealed that seroprevalence dramatically increased over time, with only a tiny fraction of seropositive individuals in August (0.3%), to increase up to more than 20-fold in October (7.0%) and to reach one-third of the overall population exposed by the end of 2020 (34.2%). While non age-specific trends were detected in infection rates across different age categories, in all three rounds of the seroprevalence study two out of three positive participants did not report any sign and/or symptom compatible with COVID-19. The serial cross-sectional surveys experience in Jordan allowed to gain additional insights of the epidemic over time in combination with context-specific aspects like adherence to public health and social measures (PHSM). On the other hand, such findings would be helpful for planning of public health mitigation measures like vaccinations and tailored restriction policies.

ATTACHED, DETACHED and WITHOUT inhaler technique coaching tools to optimize pMDI use competence, asthma control and quality-of-life in asthmatic adults.

BACKGROUND: Poor pressurized metered dose inhaler (pMDI) technique is prevalent, which will diminish treatment gains. In a two-visit study, two novel pMDI training devices with feedback mechanisms; Trainhaler (THR) and Flo-Tone CR (FTCR), were evaluated alongside the traditional verbal inhaler training (VT) in asthma outpatients. METHODS: On visit 1, 18-60 year-old asthmatics with incorrect pMDI use [including peak inhalation flow (PIF) >60 L/min] signed consent and baseline pMDI technique, lung function, asthma control and quality-of-life were measured. Participants were randomized to receive pMDI technique training using VT, THR or FTCR. One hour post-training, the pMDI coordination and PIF were re-assessed. The THR and FTCR patients were given their assigned tools to take home to facilitate regular training. All outcomes were re-evaluated 6-8 weeks later (visit 2). RESULTS: Ninety-two asthmatics completed visit 1 (46 attended visit 2). Pre-training, 61.3% (VT), 61.5% (THR) and 65.0% (FTCR) patients similarly made ≥2 pMDI errors with mean PIFs 175.2, 187.1 and 158.9 L/min, respectively. pMDI use was significantly improved 1 h post-training. The subjects that completed visit 2 had significantly, yet equally, maintained the improved inhaler use; only 28.0% (VT), 26.2% (THR) and 21.7% (FTCR) patients made ≥2 pMDI errors with PIF improvements; 115.3, 94.6 and 96.1 L/min, respectively. Clinical outcomes remained comparable. CONCLUSIONS: VT improves the overall pMDI technique, however patients gradually forget their VT. The THR and FTCR devices are retained by the patients as their self-monitoring, all-time personal trainers that boost and maintain their VT between routine clinic visits.

Inhaler technique education and asthma control among patients hospitalized for asthma in Jordan.

OBJECTIVES: To investigate the effect of inhaler technique education delivered by a clinical pharmacist to patients hospitalised for asthma, on inhaler technique scores and asthma control at three months post-discharge. METHODS: This pre-post interventional study in Jordan enrolled patients who had been admitted for asthma and were using controller medication by Accuhaler [Diskus] (ACC), Turbuhaler (TH) or Pressurized metered dose inhalers (pMDI). Inhaler technique was assessed using published checklists (score 0-9). Asthma symptom control was assessed by Asthma Control Test (ACT, range 5-25). Patients were assessed on admission (baseline), pre-discharge, and 3 months later. All patients received a 'Show-and-Tell' inhaler technique counseling service prior to discharge. RESULTS: Baseline data were available for 140 patients, 71% females, mean age 52.7 (SD 16.64) years, mean ACT score 10.0 (SD 4.8). Mean inhaler score was 7.5 (SD 1.52) with no significant difference between the inhaler groups (p = 0.174). After pre-discharge training, all patients had correct technique (score 9/9). After 3 months, mean inhaler scores were significantly higher than at baseline (8.14 (SD 0.87, p < 0.001), with mean change significantly higher for TH 1.21 (SD 2.25) and ACC 0.85 (SD 0.97) than pMDI (0.16; SD 0.72), p = 0.001. Symptom control improved significantly for all patients, with a mean increase in ACT score of 7.54 (SD 8.18), with no significant difference between the inhaler device groups (p = 0.326). CONCLUSIONS: Patients hospitalized for asthma achieved correct inhaler technique after training by a pharmacist, and maintained better technique at 3 months than on admission. Significant improvements in ACT scores were documented for all inhaler groups.

An intronic single-nucleotide polymorphism (rs13217795) in FOXO3 is associated with asthma and allergic rhinitis: a case-case-control study.

BACKGROUND: Asthma and allergic rhinitis are respiratory diseases with a significant global burden. Forkhead box O3 (FOXO3) is a gene involved in the etiology of a number of respiratory diseases. The objective of this study is to assess the association of rs13217795, an intronic FOXO3 single-nucleotide polymorphism, with asthma and allergic rhinitis. METHODS: In this case-case-control genetic association study, genotyping was conducted using the PCR-RFLP method. Genotype-based associations were investigated under the general, recessive, and dominant models of disease penetrance using binomial logistic regression; and, allele-based associations were tested using Pearson's chi-squared test. RESULTS: The final study population consisted of 94 controls, 124 asthmatics, and 110 allergic rhinitis patients. The general and recessive models of disease penetrance were statistically significant for both case-control comparisons. Under the general model, the odds of the asthma phenotype were 1.46 (0.64 to 3.34) and 3.42 (1.37 to 8.57) times higher in heterozygotes and derived allele homozygotes, respectively, compared to ancestral allele homozygotes. The corresponding odds ratios for the allergic rhinitis phenotype were 1.05 (0.46 to 2.40) and 2.35 (0.96 to 5.73), respectively. The dominant model of disease penetrance was not statistically significant. The minor allele in all study groups was the ancestral allele, with a frequency of 0.49 in controls. There was no deviation from Hardy-Weinberg equilibrium in controls. Both case-control allele-based associations were statistically significant. CONCLUSIONS: Herein we present the first report of the association between rs13217795 and allergic rhinitis, and the first independent verification of the association between rs13217795 and asthma. Marker selection in future genetic association studies of asthma and allergic rhinitis should include functional polymorphisms in linkage disequilibrium with rs13217795.

Molecular evidence for the absence of an association between Simkania negevensis and respiratory diseases.

Simkania negevensis has been implicated in respiratory diseases. This study aimed to unveil the aetiological role of this bacterium in community-acquired pneumonia (CAP) and bronchitis in Jordanian adults. Nasopharyngeal samples were collected from 98 CAP or bronchitis patients and 96 control individuals, and tested for Simkania nucleic acids using a PCR assay. The overall prevalence of the bacterial DNA in patients was markedly high and reached 57.1 %. Intriguingly, Simkania DNA was detected in 62.5 % of the nasopharyngeal swabs collected from apparently healthy controls (P>0.05). The DNA positivity in the bronchitis and CAP subgroups was 57.7 and 56.9 %, respectively, percentages that are approximately comparable to the DNA positivity assessed for the entire patient population. Simkania is most likely not a causative agent of CAP or bronchitis, despite its remarkable high prevalence. This organism, in the nasopharynx, is potentially harmless to the host and may coexist in a commensal relationship.

Effect of novel inhaler technique reminder labels on the retention of inhaler technique skills in asthma: a single-blind randomized controlled trial.

Inhaler technique can be corrected with training, but skills drop off quickly without repeated training. The aim of our study was to explore the effect of novel inhaler technique labels on the retention of correct inhaler technique. In this single-blind randomized parallel-group active-controlled study, clinical pharmacists enrolled asthma patients using controller medication by Accuhaler [Diskus] or Turbuhaler. Inhaler technique was assessed using published checklists (score 0-9). Symptom control was assessed by asthma control test. Patients were randomized into active (ACCa; THa) and control (ACCc; THc) groups. All patients received a "Show-and-Tell" inhaler technique counseling service. Active patients also received inhaler labels highlighting their initial errors. Baseline data were available for 95 patients, 68% females, mean age 44.9 (SD 15.2) years. Mean inhaler scores were ACCa:5.3 ± 1.0; THa:4.7 ± 0.9, ACCc:5.5 ± 1.1; THc:4.2 ± 1.0. Asthma was poorly controlled (mean ACT scores ACCa:13.9 ± 4.3; THa:12.1 ± 3.9; ACCc:12.7 ± 3.3; THc:14.3 ± 3.7). After training, all patients had correct technique (score 9/9). After 3 months, there was significantly less decline in inhaler technique scores for active than control groups (mean difference: Accuhaler -1.04 (95% confidence interval -1.92, -0.16, P = 0.022); Turbuhaler -1.61 (-2.63, -0.59, P = 0.003). Symptom control improved significantly, with no significant difference between active and control patients, but active patients used less reliever medication (active 2.19 (SD 1.78) vs. control 3.42 (1.83) puffs/day, P = 0.002). After inhaler training, novel inhaler technique labels improve retention of correct inhaler technique skills with dry powder inhalers. Inhaler technique labels represent a simple, scalable intervention that has the potential to extend the benefit of inhaler training on asthma outcomes. ASTHMA: REMINDER LABELS IMPROVE INHALER TECHNIQUE: Personalized labels on asthma inhalers remind patients of correct technique and help improve symptoms over time. Iman Basheti at the Applied Science Private University in Jordan and co-workers trialed the approach of placing patient-specific reminder labels on dry-powder asthma inhalers to improve long-term technique. Poor asthma control is often exacerbated by patients making mistakes when using their inhalers. During the trial, 95 patients received inhaler training before being split into two groups: the control group received no further help, while the other group received individualized labels on their inhalers reminding them of their initial errors. After three months, 67% of patients with reminder labels retained correct technique compared to only 12% of controls. They also required less reliever medication and reported improved symptoms. This represents a simple, cheap way of tackling inhaler technique errors.

Role of Chlamydia pneumoniae in community-acquired pneumonia in hospitalized Jordanian adults.

INTRODUCTION: This study investigated the role of Chlamydia pneumoniae in the etiology of community-acquired pneumonia (CAP) in Jordanian adults. METHODOLOGY: Eighty hospitalized CAP patients and 110 healthy adults were enrolled. Overall prevalences of C. pneumoniae IgG antibodies in sera and the rate of acute infection were estimated, using the microimmunofluorescence method (MIF), at titers of 1:16 and 1:512, respectively. Moreover, a nested polymerase chain reaction (PCR) was used to detect C. pneumoniae DNA in nasopharyngeal and blood Buffy coat samples. RESULTS: Overall chlamydial IgG prevalence was higher in CAP cases than controls (70% versus 61.8%). Similarly, higher rate of acute infection was found in patients than in controls (16.3% versus 5.5%). By focusing on subjects testing positive at 1:16, acute infection was detectable in 23.2% of CAP cases, compared with 8.8% of seropositive controls. Chlamydial DNA was confirmed in 8.2% and 8.8% of nasopharyngeal specimens from controls and patients, respectively. Moreover, 10.9% and 7.5% of Buffy coats from controls and cases, respectively, were PCR-positive. When performances of both assays for detection of the pathogen were assessed, the sensitivities of MIF and PCR were low and comparable. However, MIF demonstrated higher specificity, positive predictive value, and negative predictive value than PCR. CONCLUSIONS: MIF-based data indicate that C. pneumoniae could be a potential causal agent of CAP in Jordan. This study may serve as a basis to elucidate the exact role C. pneumoniae and other co-infecting pathogens in the etiology of respiratory tract disease.

Home medication management review in outpatients with chronic diseases in Jordan: a randomized control trial.

BACKGROUND: Medication Management Review (MMR) is a patient-focused, structured and collaborative health care service provided in the community setting to optimize patient understanding and quality use of medicines. OBJECTIVE: To conduct a randomized control trial of the MMR program in Jordan, by a pharmacist identifying treatment related problems (TRPs) through home visits, assessing type and frequency of TRPs, and eventual effect of resolving TRPs identified by the pharmacist and accepted by the physician on the health status of participating patients. SETTING: Outpatient clinic at the Jordan University Hospital, Amman, Jordan. METHOD: Consecutive patients from outpatient clinics who were eligible for the study were recruited and randomly distributed into two groups (control and intervention). All patients were visited at home by the pharmacist who delivered only for intervention group counseling regarding self-reported adherence, frequency of monitoring and education regarding pharmacological and non-pharmacological therapy. After identifying TRPs, the pharmacist sent a letter to the physician with certain recommendations for patients in the intervention group only. Physician ticked the approved recommendations and returned the report to the pharmacist, allowing the pharmacist to convey the approved changes to the patients. Patients were referred back to their physicians for confirmation of any changes in treatment. Both groups were reassessed after 2-3 months during their regular follow-up visits to their physicians. MAIN OUTCOME MEASURE: To assess the impact of home medication review on the number of TRPs and self-reported adherence in outpatients with chronic diseases via hospital-based clinics in Jordan. RESULTS: A total of 158 TRPs were identified in 112 patients; mean TRP number was 1.63 per patient. As a result of the pharmacist intervention, there was a significant decrease in number of TRPs in the intervention group, the change in the mean was (1.23 (±1.19), P < 0.001) versus the control group (0.29 (±1.24), P = 0.114). After 3 months, a reduction in non-adherence was observed in the intervention (-0.81 (±1.48), P < 0.001) in contrast to no change in self-reported adherence in the control (0.22 (± 1.12), P = 0.168) group. CONCLUSION: Overall, home-based medication review for patients with chronic conditions decreased the total number of TRPs and improved patient self-reported adherence.

Association Between Gasdermin A and Gasdermin B Polymorphisms and Susceptibility to Adult and Childhood Asthma Among Jordanians.

INTRODUCTION: Gasdermin A (GSDMA) and gasdermin B (GSDMB) have been associated with childhood, and to a lesser extent with adult, asthma in many populations. AIMS: In this study, we investigated the association between GSDMA and GSDMB variants and the incidence of adult and childhood asthma among Jordanians. METHODS: Subjects were divided into two groups: adults and children. Within the adult group there were 129 asthma patients and 111 healthy controls. In the pediatric group there were 98 asthma patients and 112 healthy children. Gasdermin A (GSDMA) (rs7212938, T/G) and Gasdermin B (rs7216389, T/C) polymorphisms were genotyped using the PCR-RFLP method. Three analysis models were applied to the genotype data: co-dominant, dominant and recessive. RESULTS: An association between the GSDMB T/C single nucleotide polymorphism (SNP) genotype and the incidence of childhood asthma was found (< 0.05). GSDMB T/C SNP in children also showed a very high tendency toward significance with p = 0.0532 in the single locus analysis. In adults, no significant differences in the allelic frequencies of any of the SNPs analyzed were found between the case and control populations. At the haplotype level, GC haplotype was found to be associated with the risk of asthma in children while none of the tested haplotypes were found to be associated with asthma risk in adults. CONCLUSIONS: The findings of this study confirm the previously reported association between the GSDMB gene and the risk of childhood asthma.

Sex-specific parameters of ascending aorta, descending aorta and pulmonary trunk by computed tomographic angiography with impact of age, hypertension, smoking and diabetes / Parámetros específicos de la parte ascendente de la aorta, parte descendente de la aorta y tronco pulmonar analizados mediante angiografía por tomografía computadorizada relacionados con el sexo, impacto de la edad, hipertensión, tabaquismo y diabetes

This study aims at establishing whether transverse diameter (TD) and cross sectional-area (CSA) of the ascending aorta (AA), descending aorta (DA) and pulmonary trunk (PT) measured by computerized tomographic angiography (CTA) altered by sex, age, hypertension, smoking and diabetes. CTA examinations of the TD and CSA of the AA, DA and PT of 100 patients aged 49.5±16.9 years (range 16­78 years) selected between January 2009 to May 2011 from those referred to Radiology Department, Jordan University Hospital, Faculty of Medicine, University of Jordan, Amman, Jordan for advanced evaluation. Measurements were made in the axial plane at the upper border of the six thoracic vertebrae. Patients were divided into three age groups. Significance of differences in parameters between age groups was calculated. Assessment ratios were considered. It was found that parameters of the three arteries were significantly larger in men than in women (P= < 0.05) and increased with age. Hypertension increased diameters of AA and DA in both genders (P= 0.001) and of PT in men (P= 0.01). Smoking significantly decreased parameters of PT in men (P= 0.01). Diabetes increased parameters of the three arteries in both genders, significantly increased parameters of PT in men (P= <0.05) and parameters of DA in women (P= <0.05). It is concluded that studied parameters were larger in men and increased with age of our patients. Distinctive differences in measurements appeared in hypertensive, smokers, and diabetic patients.

El objetivo fue determinar si el sexo, edad, hipertensión, tabaquismo y la diabetes alteran el diámetro transversal (DT) y área transversal (AT) de la parte ascendente de la aorta (AA), parte descendente de la aorta (AD) y tronco pulmonar (TP), medidos por angiografía por tomografía computadorizada (ATC). Exámenes de ATC de 100 pacientes de 49,5±16,9 años (rango 16­78 años) fueron seleccionados entre enero del año 2009 a mayo del año 2011 por el Departamento de Radiología, Hospital de la Universidad de Jordania, Facultad de Medicina de la Universidad de Jordania, Amman, Jordania para una evaluación avanzada del DT y AT de la AA, AD y TP. Las mediciones se realizaron en el plano axial en el margen superior de las seis vértebras torácicas. Los pacientes fueron divididos en tres grupos según edad. Se determinó la existencia de significancia estadística de los diferentes parámetros entre los grupos etarios. La evaluación de las razones también fueron consideradas. Se encontró que los parámetros de las tres arterias fueron significativamente mayores en los hombres que en las mujeres (p= <0,05) y que aumentaron con la edad. La hipertensión aumentó los diámetros de la AA y AD en ambos sexos (p= 0,001) y del TP en los hombres (p= 0,01). En fumadores disminuyeron significativamente los parámetros del TP en los hombres (p= 0,01). La diabetes aumentó los parámetros de las tres arterias en ambos sexos. Ademas, aumentaron significativamente los parámetros del TP en los hombres (p= <0,05) y los parámetros de la AD en las mujeres (p = <0,05). Se concluye que los parámetros estudiados eran mayores en los hombres y aumentaron con la edad de nuestros pacientes. Diferencias distintivas en las mediciones aparecieron en hipertensos, fumadores y pacientes diabéticos.
