Telemonitoring in patients with asthma: a systematic review.

BACKGROUND: Monitoring and managing asthma using technology can help increase patient adherence and achieve better asthma control. This study aimed to evaluate the effectiveness of telemonitoring using smartphones and telephone communication compared to usual outpatient clinical evaluation in patients with asthma. DATA SOURCES: This systematic review was conducted in 2023. Databases PubMed, Scopus, Web of Science, and the Google Scholar search engine, were searched from 2013 to 2022. DATA SELECTION: The selected studies were randomized clinical trials that used telemonitoring in patients with asthma. The quality of the studies was evaluated using the JADAD scale. Data were collected using a data extraction form, and the findings were synthesized narratively. This systematic review was conducted following the PRISMA checklist. RESULTS: Initially, 4,147 articles were found, of which 14 were included in the study. The results showed that in some cases, telemonitoring using smartphones and telephone communication in patients with asthma is effective, while in other studies, its effectiveness was not observed. CONCLUSIONS: Telemonitoring using smartphones and telephone communication in patients with asthma can be considered an appropriate strategy to reduce the use of healthcare resources and improve quality of life. However, further studies are recommended to investigate the effectiveness of each of these technologies and their specific outcomes.

Follow-Up of Coronavirus Infected Patients Using Telemedicine in a Referral Pulmonary Center.

BACKGROUND: Telemedicine is considered an innovative approach for management and follow up of communicable diseases, when person to person contact has the risk of disease dissemination, such as the situation being experienced with corona virus infection. The aim of this study was to evaluate the role of telemedicine in patient follow-up and patient compliance in different communication methods. MATERIALS AND METHODS: All patients discharged from a referral pulmonary hospital dedicated to coronavirus infected patients were given instructions on follow-up of symptoms. One group received messages via short message system regarding the severity of their symptoms. For the other group a mobile application was specially designed for tracking their well-being on a daily basis. Severity of symptoms and course of disease were monitored in each group for a two-month period. RESULTS: A total 1091 patients with mean age of 53.96± 17.95 years were enrolled in the study. In the first group 406 (60.14%) messages were successfully sent, from which 150 (36.94%) patients replied. Also, 243(35%) patients contacted us by making phone calls. Of the total patients in the second group, 153(64%) patients started using the mobile application. Chief complaint of patients was mainly cough, shortness of breath, fatigue, and myalgia. Deep vein thrombosis, hyperglycemia, post kidney transplant patient and bloody diarrhea were among the reported cases. CONCLUSION: Patient follow-up during epidemics, especially when the disease course is unknown, is an important step in both successful patient management and disease control. This study showed the role of telemedicine for patient follow-up, mostly in detecting special situations. But, in order to be successful patient education and active follow-up are important factors that must be considered.

High-Frequency Jet Ventilation in Nonintubated Patients.

OBJECTIVES: High-frequency jet ventilation (HFJV) is a convenient method for providing ventilation during fiberoptic bronchoscopy. We describe an incipient approach of high-frequency jet ventilation via the working channel of a flexible bronchoscope for nonintubated patients who suffer from hypoxemia during bronchoscopy. The aim of this study was to test the efficacy of this incipient approach and determine the possible complications related to it. MATERIALS AND METHODS: Sixteen patients who had oxygen saturation below 70% that did not resolve with nasal oxygen for 20 s during interventional bronchoscopy were included in the study. High-frequency jet ventilation was administrated via the working channel of a bronchoscope for 3 min. Arterial blood gas circumscriptions were compared before and after jet ventilation. RESULTS: Oxygen saturation increased to >90% in all patients 30 s after jet ventilation. Mean arterial oxygen saturation pressure increased from 54.84 to 111.98 mmHg with jet ventilation (p=0.0001). Arterial carbon dioxide tension decreased after jet ventilation. The body mass index had no consequential effect on arterial carbon dioxide pressure after jet ventilation in our patients (p=0.1). Complications such as pneumothorax and working channel damage were not observed. CONCLUSION: High-frequency jet ventilation via the working channel of the bronchoscope is a novel method that can provide optimal ventilation with minimal complications to nonintubated patients suffering from hypoxemia during bronchoscopy. This method also reduces the duration of bronchoscopy procedures.

Role of Telemedicine in Pace of Consultation and Physicians' Satisfaction in Thoracic Surgery ICU.

BACKGROUND: Despite various applications of tele-ICU, there are still many questions about its costs and advantages in ICU. Some of its advantages are accelerating consultations and bringing physicians' satisfaction from tele-consultation outcomes. The aim of this study is to discuss these advantages. MATERIALS AND METHODS: Initially a telemedicine network was implemented and in the case of having no related specialist, the physicians used telemedicine network to perform specialized tele-consultation to thoracic surgery ICU patients. ICU patient's documents during a year before tele-consultation were studied and delay time in consultation was recorded and compared between the two phases. Finally, the physicians' satisfaction with tele-consultation was evaluated. RESULTS: Fifty-eight tele-consultations in various medical fields were carried out, of which 27 were neurology cases. From the time of receiving a consultation request to its performance, the mean time was 1.3 days in tele-consultation. Tele-consultations were given 2.5 times faster than face to face method. In evaluation of physicians' satisfaction, 82.75% of them were fully satisfied from tele-consultation, 12.06% were partly satisfied and 5.17% were not satisfied. CONCLUSION: Since the length of hospitalization in ICU is crucial due to heavy costs of treatment, high risk of contamination and limited beds, performing timely consultation is a key factor in reducing hospitalization period. Tele-consultation in thoracic surgery ICU not only accelerates patient care, but also results in higher physician satisfaction.

Third study on WHO MPOWER Tobacco Control Scores in Eastern Mediterranean countries 2011-2015.

This study was conducted to quantify the implementation of the MPOWER policies and to assess any possible changes across Eastern Mediterranean Region (EMR) countries. In this comparative cross-sectional study based on 10 categories mentioned in MPOWER report 2015 a checklist was designed. Seven questions were scored from 0-4 and three from 0-3. The 22 EMR countries were ranked and compared by their total score on a scale of 0-37. The highest scores were achieved by Egypt and the Islamic Republic of Iran. Pakistan, Sudan and Yemen showed progress, while Bahrain, Jordan, Kuwait, Oman, and the Syrian Arab Republic had decreased scores. The total score of the EMR countries had decreased compared to 2013. Thus, there remains a need for greater focus on tobacco taxation and smoke-free policies to address this retrograde step.

Electronic cigarette, effective or harmful for quitting smoking and respiratory health: A quantitative review papers.

BACKGROUND: In recent years, electronic cigarettes (ECs) have been heavily advertised as an alternative smoking device as well as a possible cessation method. We aimed to review all published scientific literature pertaining to ECs and to present a simple conclusion about their effects for quitting smoking and respiratory health. METHODS: This was a cross-sectional study with a search of PubMed, limited to English publications upto September 2014. The total number of papers which had ECs in its title and their conclusions positive or negative regarding ECs effects were computed. The number of negative papers was subtracted from the number of positive ones to make a score. RESULTS: Of the 149 articles, 137 (91.9%) were accessible, of which 68 did not have inclusion criteria. In the 69 remaining articles, 24 studies supported ECs and 45 considered these to be harmful. Finally, based on this evidence, the score of ECs (computed result with positive minus negative) was -21. CONCLUSION: Evidence to suggest that ECs may be effective and advisable for quitting smoking or a safe alternative for smoking is lacking and may instead harm the respiratory system. However, further studies are needed.

Home spirometry: Assessment of patient compliance and satisfaction and its impact on early diagnosis of pulmonary symptoms in post-lung transplantation patients.

Telemedicine is useful in monitoring patients, and in particular those, such as lung transplant recipients, suffering from chronic illnesses. This prospective cohort study was conducted on 15 lung transplant recipients. The patients provided physicians with data from spirometry as well as their clinical respiratory symptoms via SMS messages. In cases where spirometry results or clinical symptoms required follow-up, the monitoring physician contacted the patient according to guidelines and gave appropriate instructions. Qualitative assessment of satisfaction showed that the sense of increased support from medical staff was rated highest (92.9%). Telespirometry is an efficient method of monitoring lung transplant recipients which leads to patient satisfaction, compliance, adherence to study and sense of security. Nevertheless, for optimal implementation of this method, thorough training of both medical staff and patients is required.

Time trend of smoking scenes in Iranian movies during the past three decades (1982-2011): a historical analysis.

BACKGROUND: Evidence from the USA and elsewhere has linked smoking depictions in movies with youth smoking initiation. Prior research has not focused on depictions in films produced in the Middle East, however. OBJECTIVE: We reviewed the 10 most commercially successful Iranian films released each year over three decades (1982-2011) to determine trends in depictions of tobacco use over time. METHODS: Each movie was reviewed in its entirety, and depictions of smoking were recorded and classified as direct (characters holding or using tobacco products) and indirect (tobacco products appearing in the frame, but not being used). Time trends in average duration of direct, indirect and total smoking depictions were analysed using linear regression and Cohen's κ coefficient. RESULTS: The mean duration of tobacco depictions in the most commercially successful Iranian films fluctuated yearly over the 3 decades, but with an overall significant upward trend (p<0.005). The proportion of movies depicting tobacco consumption during the three decades was 36% (1982-1991), 60% (1992-2001) and 74% (2002-2011), respectively. The average proportion of total movie time for these depictions (0.75%, 1.41%, 2.08%) increased significantly (p<0.005) over the 3 decades as did the average duration of smoking depictions,(39.1, 67 and 99.3 s, respectively, p<0.005). CONCLUSIONS: The significant increase in the proportion of movies depicting tobacco consumption and in the duration of smoking depictions over the past 30 years underscores the need for increased regulation of the Iranian film industry to minimise this important source of influence on tobacco initiation in young people.

Comparison of Tobacco Control Programs Worldwide: A Quantitative Analysis of the 2015 World Health Organization MPOWER Report.

BACKGROUND: A report of the activities of countries worldwide for six main policies to control tobacco use is published once every 2 years by the World Health Organization (WHO). Our objective was to perform a quantitative analysis for it in countries and regions to make a simple view of its programs. METHODS: This was a cross-sectional study by filling out a validated checklist from the 2015 WHO Report (MPOWER). All ten MPOWER measures got scores and were entered independently by two individuals and a third party compared the values. RESULTS: Fifteen countries, which acquired the highest scores (85% of total 37), included Panama and Turkey with 35, Brazil and Uruguay with 34, Ireland, United Kingdom, Iran, Brunei, Argentina, and Costa Rica with 33, and Australia, Nepal, Thailand, Canada, and Mauritius with 32 points. CONCLUSIONS: Comparison of scores of different countries in this respect can be beneficial since it creates a challenge for the health policymakers to find weakness of the tobacco control programs to work on it.

Key Policy Makers' Awareness of Tobacco Taxation Effectiveness through a Sensitization Program.

The implementation of 5 of the 6 WHO MPOWER program in Iran is satisfactory; the only notable shortcoming is the lack of tobacco taxation increases. This study was designed to increase key policy makers' awareness of tobacco taxation effectiveness through a sensitization program in Iran. This analytical and semi-experimental study in 2014 included 110 tobacco control key policy makers, who were trained and received educational materials on the importance of tobacco taxation. A valid and reliable questionnaire was completed before and three months after intervention. Data were analyzed using mean (SD), t-Test and analysis of variance. The mean (SD) scores at pre- and post-test were 2.7 ± 3 and 8.8 ± 1 out of 10, respectively. Paired t-tests demonstrated a significant difference in the pre- post-test knowledge scores. Increasing knowledge and promoting favorable attitudes of policy makers can lead to greater attention which could in turn change tobacco taxation policies.

Assessment of Different Quit Smoking Methods Selected by Patients in Tobacco Cessation Centers in Iran.

BACKGROUND: Health systems play key roles in identifying tobacco users and providing evidence-based care to help them quit. This treatment includes different methods such as simple medical consultation, medication, and telephone counseling. To assess different quit smoking methods selected by patients in tobacco cessation centers in Iran in order to identify those that are most appropriate for the country health system. METHODS: In this cross-sectional and descriptive study, a random sample of all quit centers at the country level was used to obtain a representative sample. Patients completed the self-administered questionnaire which contained 10 questions regarding the quality, cost, effect, side effects and the results of quitting methods using a 5-point Likert-type scale. Percentages, frequencies, mean, T-test, and variance analyses were computed for all study variables. RESULTS: A total of 1063 smokers returned completed survey questionnaires. The most frequently used methods were Nicotine Replacement Therapy (NRT) and combination therapy (NRT and Counseling) with 228 and 163 individuals reporting these respectively. The least used methods were hypnotism (n = 8) and the quit and win (n = 17). The methods which gained the maximum scores were respectively the combined method, personal and Champix with means of 21.4, 20.4 and 18.4. The minimum scores were for e-cigarettes, hypnotism and education with means of 12.8, 11 and 10.8, respectively. There were significant differences in mean scores based on different cities and different methods. CONCLUSIONS: According to smokers' selection the combined therapy, personal methods and Champix are the most effective methods for quit smoking and these methods could be much more considered in the country health system.

Quit Smoking Experts' Opinions toward Quality and Results of Quit Smoking Methods Provided in Tobacco Cessation Services Centers in Iran.

BACKGROUND: One of the core responsibilities of health system is to treat tobacco dependence. This treatment includes different methods such as simple medical consultation, medication, and telephone counseling. To assess physicians' opinions towards quality and result of different quit smoking methods provided in tobacco cessation services centers in Iran. METHODS: In this cross-sectional and descriptive study, random sampling of all quit centers at country level was used to obtain a representative sample size of 100 physicians. Physicians completed a self-administered questionnaire which contained 10 questions regarding the quality, cost, effect, side effects, and the results of quitting methods using a 5-point Likert-type scale. Percentages, frequencies, mean, T-test, and variance analyses were computed for all study variables. RESULTS: Most experts preferred to use combination quit smoking methods and then Nicotine Replacement Therapy (NRT) with 26 and 23, respectively. The least used methods were quit line and some methods without medication with 3 cases. The method which gained the maximum scores were telephone consultation, acupuncture, Willpower, Champix, combined method, and Interactive Voice Response (IVR) with the mean of 23.3, 23, 22.5, 22, 21.7 and 21.3, respectively. The minimum scores were related to e-cigarette, some methods without medication, and non-NRT medication with the mean of 12.3, 15.8 and 16.2, respectively. There were no significant differences in the mean of scores based on different cities (P = 0.256). Analysis of variance in mean scores showed significant differences in the means scores of different methods (P < 0.000). CONCLUSIONS: According to physicians acupuncture, personal methods and Champix are the most effective methods and these methods could be much more feasible and cost effective than other methods.

Use of Bispectral Index Score for Interventional Bronchoscopy Procedures.

BACKGROUND: Interventional bronchoscopic procedures are novel diagnostic and therapeutic methods in pulmonology, which may be unpleasant and dangerous to the patients; therefore, sedation and in some cases general anaesthesia are recommended. But adjusting the level of sedation is a challenge. In this study we intended to define a range of bispectral index (BIS) score suitable for these procedures. MATERIALS AND METHODS: All patients referred to our interventional bronchoscopy unit were enrolled in the study. Sedation was induced using midazolam, sufentanil, and propofol with the patient breathing spontaneously. The target level of sedation was to reach a Ramsay sedation score of 3 and patient tolerance in performing the procedure. The BIS score was recorded at baseline and every five minutes thereafter. Correlation between different BIS values, propofol dosage, duration of procedure, and awakening time was evaluated. RESULTS: A total of 70 patients were enrolled in this study with a mean age of 50± 16 years and 34 (48.6%) of them were males. The mean baseline BIS was 96±3.7, and the mean time to reach "stable BIS" ("stable time") was 7.9±6 minutes. The mean "stable BIS" was 52±13.5 and 70% of patients had stable BIS between 40 and 60. CONCLUSION: BIS is a useful objective tool for evaluation of sedation, which can guide us through bronchoscopy and related procedures. According to our observational study, reaching the mean BIS level of 52±13.5 is required to prevent complications and ensure feasibility of the procedure.

The second study on WHO MPOWER tobacco control scores in Eastern Mediterranean Countries based on the 2013 report: improvements over two years.

BACKGROND: Following MPOWER's 2011 report, a study was conducted to quantify the implementation of MPOWER tobacco control policies in the Eastern Mediterranean Region (EMR) in 2013 to assess any possible change during the last two years.  METHODS: In this cross sectional study, based on 10 categories mentioned in MPOWER 2013, a checklist was designed and its scoring was agreed upon by Iranian and international tobacco control specialists. Seven questions were scored from 0 - 4 and 3 from 0 - 3. The 22 countries were ranked by their total score on a scale of 0 to 37.  RESULTS: Among the 22 countries in the EMR, Iran, Kuwait, Egypt, Lebanon, Gaza and West bank and Jordan were scored 31, 28, 28, 26, 25 and 25 respectively. 14 countries scored more than 50%, a small improvement; 5 countries have seen their scores fall, and three countries received the same score as last time. The highest overall improvement was attributed to the warning label, and the sharpest decline was observed in the consumption category. CONCLUSION: There has been a slight overall improvement in tobacco control planning, although the desired levels have yet to be reached and some countries in the region have fared worse.

Prevalence and risk factors of asthma and allergic diseases in primary schoolchildren living in Bushehr, Iran: phase I, III ISAAC protocol.

Asthma and allergic diseases present a major health burden. Information on the prevalence of these diseases indicates that these diseases are increasing in various parts of the world. It was hoped that this study would be helpful to health system policy-makers in planning allergy prevention programs in the region.The prevalence of asthma and allergic diseases and relation between the various risk factors involved were assessed among schoolchildren in the city of Bushehr, Iran. The ISAAC Phase I and III questionnaires were completed by parents of 1280 children aged 6-7 years and self-completed by 1115 students aged 13-14 years.The prevalence of atopic eczema, allergic rhinitis and asthma among 6-7 year-old students were 12.1%, 11.8% and 6.7%, respectively. While, the prevalence of these diseases among 13-14 year-old students were found to be 19%, 30% and 7.6%, respectively. There was an association between asthma and allergic rhinitis as well as eczema (p<0.05). Consumption of fast food as a risk factor was significantly associated with asthma (p=0.03).The prevalence of asthma and allergic diseases was high among schoolchildren in the city of Bushehr, Iran. Also an association was observed between the fast food consumption and asthma.

A comparative study on tobacco cessation methods: a quantitative systematic review.

BACKGROUND: During recent years, there have been many advances in different types of pharmacological and non-pharmacological tobacco control treatments. In this study, we aimed to identify the most effective smoking cessation methods used in quit based upon a review of the literature. METHODS: We did a search of PubMed, limited to English publications from 2000 to 2012. Two trained reviewers independently assessed titles, abstracts and full texts of articles after a pilot inter-rater reliability assessment which was conducted by the author (GH). The total number of papers and their conclusions including recommendation of that method (positive) or not supporting (negative) was computed for each method. The number of negative papers was subtracted from the number of positive ones for each method. In cases of inconsistency between the two reviewers, these were adjudicated by author. RESULTS: Of the 932 articles that were critically assessed, 780 studies supported quit smoking methods. In 90 studies, the methods were not supported or rejected and in 62 cases the methods were not supported. Nicotine replacement therapy (NRT), Champix and Zyban with 352, 117 and 71 studies respectively were the most supported methods and e-cigarettes and non-Nicotine medications with one case were the least supported methods. Finally, NRT with 39 and Champix and education with 36 scores were the most supported methods. CONCLUSIONS: Results of this review indicate that the scientific papers in the most recent decade recommend the use of NRT and Champix in combination with educational interventions. Additional research is needed to compare qualitative and quantitative studies for smoking cessation.

Thoracoscopic lobectomy in a patient with permanent tracheostomy.

One Lung Ventilation (OLV) is the preferred method of anesthesia in the vast majority of thoracic operations, especially thoracoscopic procedures. Although double lumen endotracheal tubes are usually used to conduct OLV during thoracic operations, in patients with permanent tracheostomy, because of short trachea, keeping these tubes safe in place is usually difficult. Thus, OLV in patients with permanent tracheostomy may be challenging or even impossible. Herein, we report a patient with permanent tracheostomy who underwent successful OLV and thoracoscopic lobectomy.

Anaesthesia Management During Interventional Bronchoscopic Procedures: Laryngeal Mask Airway or Rigid Bronchoscope.

OBJECTIVE: Interventional bronchoscopy procedures are novel and effective modes of diagnosing and treating airway lesions. Airway management and ventilation are a major concern, especially when considering the fire hazard of ventilating during endobronchial thermal therapies. The aim of this study was to evaluate the usage of laryngeal mask airway (LMA) compared to rigid bronchoscopy for the ventilation of patients undergoing diagnostic or therapeutic interventional bronchoscopy procedures. METHODS: During this prospective randomised clinical trial study, patients were randomly allocated to two groups for ventilation: LMA and rigid bronchoscopy. Vital signs, including blood pressure, heart rate and percentage of blood O2 saturation before and during the procedure, degree of sore throat after recovery and physician's satisfaction, were recorded. RESULTS: A total of 83 patients, including 45 in the "LMA" and 38 in the "rigid" groups, were enrolled in this study. Their mean age was 51±17 years, and 59 (71%) were male. There was a statically significant difference between "rigid" and "LMA" categories regarding the decrease in O2 during the procedure in proportion to baseline figures (p=0.028). Haemodynamic parameters were better maintained using LMA compared to rigid bronchoscopy. CONCLUSION: Laryngeal mask ventilation maintains better oxygenation and haemodynamic stability and ensures physicians' and patients' satisfaction regarding ease of use, airway access and fewer complications compared to rigid bronchoscopy. Therefore, LMA can be introduced as a reliable alternative for ventilation during interventional airway procedures.

Role of laryngeal mask airway in interventional bronchoscopy procedures for upper tracheal stenosis: case series.

BACKGROUND: Bronchoscopic interventional procedures are novel means of treating airway lesions which are less invasive and well tolerated for patients with endo-luminal lesions, but managing the airway and oxygenating the patient in a field that is shared by both anesthesiologist and bronchoscopist is a major concern. Also in cases with subglottic and upper tracheal stenotic lesions an airway device placed inside the lumen interferes with the procedure and occasionally bears the hazard of ignition. Therefore, an airway device placing above the glottis with effective oxygenation is required. Laryngeal mask airway is a supra-glottic device which facilitates assisted or spontaneous positive pressure ventilation. METHODS: In this study, eight patients with subglottic stenoses due to different etiologies are presented who underwent fiberoptic bronchoscopy and therapeutic interventions through laryngeal mask. RESULTS: In all these patients, we experienced simple access to the vocal cord, glottis and trachea and also the lesion, besides effective oxygenation of the patient. Furthermore, bronchoscopist and patients were both comfortable with the procedures. CONCLUSION: Laryngeal mask airway could be regarded as a reliable alternative for airway management during interventional bronchoscopic procedures, especially when they are located near the glottis or in the upper third of the trachea.
