The Perceived Informational Needs of Family Caregivers of Children Hospitalized in a Burn Department: A Cross-sectional Study.

Children are most vulnerable to burn injuries, and their families are their most important source of support. Therefore, it is necessary to identify the information needs of such parents and support them to help children adapt to the new situation, recover to pre-accident conditions, and reintegrate into school and society. This study aimed to investigate the perceived information needs of family caregivers of children admitted to the burn wards of hospitals. This cross-sectional study was conducted on 200 family caregivers of children admitted to the burn ward of a hospital in Tabriz, Iran. Participants were selected through convenience sampling, and the required data were collected by using questionnaires on socio-demographic information, information needs, information resources, and information acquisition methods. The obtained data were analyzed statistically using descriptive statistics (mean, standard deviation, frequency, and percentage) and inferential statistics (Mann-Whitney, Kruskal-Wallis, and Spearman correlation tests). Results indicated that the greatest informational need among family caregivers was related to the child's condition. The treatment team was identified as the most important source of information for them. It was found that information should be provided in a comprehensive and understandable manner, while maintaining honesty and human dignity. The study findings contribute to our understanding of the specific information needs of family caregivers in managing the medical care of children with burns. These findings can serve as a basis for interventions and support services aimed at meeting the needs of these families and improving the quality of care for children with burns.

Adherence to Immunosuppressants among Adult Patients after Allogeneic Hematopoietic Stem-Cell Transplantation (Allo-HSCT): A Cross-Sectional Study.

Background: The level of adherence to drug therapy after allogeneic hematopoietic stem-cell transplantation (Allo-HSCT) can affect the patient's outcome, and poor adherence is one of the factors in first-year mortality after HSCT. Material and Methods: This study assessed adherence to cyclosporine and prednisolone as the immunosuppressant regimen in 110 post-HSCT patients (> 18 years). Demographic characteristics, clinical information, and cyclosporine levels were obtained. A validated Persian medication adherence scale was used to assess adherence to cyclosporine and prednisolone. Results: For 110 patients, the calculated mean of the total score of cyclosporine and prednisolone was 7.73 ± 0.62 and 7.63 ± 0.73, respectively. Poor adherence to medication in this population was 27.7% and 22.7% to prednisolone and cyclosporine, respectively. A significant correlation was observed between adherence total score and cyclosporine levels at the third- and fourth-month post-transplant (r = 0.52, P < 0.001 and r = 0.60, P = 0.001). In the first, second, and third months, the mean of cyclosporine levels in the high adherence level was higher than the moderate and poor adherence levels. Additionally, there was an association between adherence score and the level of cyclosporine. One score increase in adherence scale on average increased cyclosporine level by 34.48 ng/ml. Conclusion: In this study, medication non-adherence was high, which indicates the need for more careful monitoring of post-HSCT patients' medication use. This is even more crucial currently since it has been confirmed that adherence can affect cyclosporine levels as the most effective immunosuppressant agent in preventing graft-versus-host disease (GVHD).

A nationwide study on consumption of opioid analgesics in Iran from 2000 to 2018.

BACKGROUND: Opioid analgesics play a unique role in pain management. National opioid consumption studies could provide indirect evidence of pain management in a country. National, regional, and global opioid consumption have been studied in other countries so far; however, conducting a focused study to illuminate the consumption of opioid analgesics over the past decades in Iran seemed necessary. AIM: The main objective of this study was to determine the consumption of opioid analgesics and explore the trend of their use during 19 years in Iran. METHOD: Iran pharmaceutical wholesale data were used to extract the annual consumption figures of the opioid analgesics in group N02A of the World Health Organization (WHO) Anatomical Therapeutic Chemical classification and were available in Iran (morphine, fentanyl, pethidine, and oxycodone as strong opioids and, tramadol and pentazocine as weak opioids), from 2000 to 2018. Using Defined Daily Dose (DDD) by WHO and Oral Morphine Equivalent (OMEQ), the amount of annual consumption was determined in DDD/1000 inhabitants/Day (DID) and OMEQ (mg)/1000 inhabitants/Day (OID). RESULTS: Total opioid analgesic utilization based on DID and OID increased 31.12-fold (from 0.0196 to 0.61) and 21.06-fold (from 1.97 to 41.5 mg) over 19 years, respectively with a significant sharp increase from 2003 to 2006 (ß = 1.78 (DID), P value < 0.001). Medications that constituted 70% of annual opioid analgesics utilization were morphine in 2000, compared to tramadol in 2018. The annual weak and strong opioids share were 86.7% and 13.2% in 2018, respectively. CONCLUSION: Despite considerable growth in the consumption of opioid analgesics in Iran over nearly two decades, the consumption amount remained low, which might signal sub-optimal pain management. On the other hand, misuse and abuse seem to be the main reason behind significant increases in the consumption of opioid analgesics with less controlled distribution.

Post-surgery Survival in Patients with Adenocarcinoma of Stomach Using Multistate Model.

PURPOSE: Stomach neoplasms are the fifth common cancer worldwide. The related factors for survival following stomach neoplasms are well-studied; however, information on recurrent events is limited. This study aimed to identify the related factors on recurrent and deaths following stomach neoplasms. METHODS: In this cohort study, information on 672 patients with adenocarcinoma who were hospitalized during 1995-2012 was used. Multistate models were applied to determine the effective factors on recurrent and death events. RESULTS: Median of survival time (months) and 5-year survival was estimated as 24.5 and 25%, respectively. The probability of death was 57% for non-recurrent patients, which increased to 88% among recurrent patients. Hazard of death was 49% lower for females (Hazard Ratio (HR):0.51, P = 0.009) while females had higher hazard of death following recurrent (HR:3.55, P < 0.001). Male patients and those with cardia involvement had higher risk of recurrence. A significant effect of age on the risk of death among patients with and without recurrence was estimated (HR:1.02, 1.03; P = 0.001 for both). Age, cardia involvement, and disease stage are amongst the effective factors on non-recurrent death while complement treatments increased the non-recurrent and recurrent survival. CONCLUSION: In patients, effects of some factors for survival may vary throughout the course of disease and depend on recurrence status. We found that while female patients experienced lower recurrence, they had higher risk of death following recurrence. Age, tumor location, and type of therapy were risk factors for non-recurrent death. Finally, tumor location and type of surgery had significant effects on recurrence.

A topical gel of tea tree oil nanoemulsion containing adapalene versus adapalene marketed gel in patients with acne vulgaris: a randomized clinical trial.

Adapalene is used for treatment of acne vulgaris, a common dermatological disease. Nano-based carriers have been developed to improve solubility and bioavailability of adapalene and other acne treatment drugs. In our previous report, tea tree oil nanoemulsion containing adapalene gel (TTO NE + ADA Gel) showed appropriate physical and biological properties such as stability, viscosity, pH, size, morphology and biocompatibility in an animal model. The present study was designed to assess efficacy and safety of the TTO NE + ADA Gel in comparison with 0.1% adapalene marketed gel (ADA Marketed Gel). A total of 100 patients were randomized to receive TTO NE + ADA Gel or ADA Marketed Gel, once daily at night, for 12 weeks. Analysis for efficacy was conducted by acne lesion count (total, inflammatory and non-inflammatory) and acne severity index at weeks 4, 8 and 12 using generalized estimating equation along with the safety assessments in each measurement for assessing dryness, erythema, burning sensation and irritation. Significantly better reduction in total, inflammatory, and non-inflammatory acne lesions were reported for TTO NE + ADA Gel as compared to the ADA Marketed Gel overall and on each measurement occasion (p value < 0.001 for all). Mean acne severity index also reduced with TTO NE + ADA Gel significantly in comparison with ADA Marketed Gel (p value < 0.001). Dryness was the most common adverse effect reported in both groups and it was higher in TTO NE + ADA Gel group. In conclusion, TTO NE + ADA Gel compared to ADA Marketed Gel appears more effective in the treatment of acne vulgaris, with no important change in adverse effects.

Detection of influenza epidemics using hidden Markov and Serfling approaches.

OBJECTIVE: Detection of epidemics is a critical issue in epidemiology of infectious diseases which enable healthcare system to better control it. This study is devoted to investigating the 5-year trend in influenza and severe acute respiratory infection cases in Iran. The epidemics were also detected using the hidden Markov model (HMM) and Serfling model. STUDY DESIGN: In this study, we used SARI data reported in the World Health Organization (WHO) FluNet web-based tool from August 2011 to August 2016. METHODS: SARI data in Iran from August 2011 to August 2016 were used. We applied the HMM and Serfling model for indicating the two epidemic and non-epidemic phases. The registered outbreak activity recorded on the WHO website was used as the gold standard. The coefficient of determination was reported to compare the goodness of fit of the models. RESULTS: Serfling models modified by 30% and 35% of the data had a sensitivity of 91.67% and 95.83%, while for 15%, 20% and 25% were 70.83%, 79.17% and 83.33%, respectively. Sensitivity of HMM and autoregressive HMM (AHMM) was 66.67% and 92.86%. All fitted models have a specificity of over 96%. The R2 for HMM and AHMM was calculated 0.73 and 0.85, respectively, showing better fitness of these models, while R2 was around 50% for different types of Serfling models. CONCLUSIONS: Both modified Serfling and HMM were acceptable models in determining the epidemic points for the detection of weekly SARI. The AHMM had better fitness, higher detection power and more accurate detection of the incidence of epidemics than Serfling model and high sensitivity and specificity. In addition to AHMM, Serfling models with 30% and 35% modification can be used to detect epidemics due to approximately the same accuracy but the simplicity of the calculations.

Assessment of Antibiotic Dispensing Practice in Community Pharmacies of Tehran, for 2 Common Infectious Symptoms, Using Simulated Patient Method.

Resistance to antibiotics is a worldwide concern and community pharmacies can play a strategic role in controlling this issue through rationalizing antibiotic consumption. Considering that dispensing any type of antibiotics without a prescription is prohibited according to Iran's regulations, this study was conducted to quantify the rate of antibiotic dispensing without a prescription by pharmacists in Tehran, Iran. A descriptive cross-sectional study was conducted from September 2016 through May 2017. Two scenarios of common infectious symptoms including sore throat and dysuria were simulated by pharmacy student in three different regions of Tehran. Each scenario was performed in three levels of demand including requesting for any medicine, asking for a stronger medicine, and direct request for an antibiotic. A total of 388 pharmacy visits were acceptable including 195 and 193 pharmacies for dysuria and sore throat, respectively. Antibiotics were provided in 39.9% of dysuria (67.5% in the first level of demand) and in 52.3% of sore throat (49% in the first level of demand) simulations. The time devoted by the pharmacists to each case was less than 60 second in more than 90% of the cases. The completion of the course of antibiotic therapy was emphasized by pharmacists in only 18% of cases in both scenarios. Our findings revealed that antibiotic dispensing without a prescription is a routine practice in community pharmacies in Tehran, Iran. Unfortunately, patient assessment and evaluation of the symptoms are not performed properly by pharmacists as well.

Out of Pocket Payment and Affordability of Medication for Geriatric Patients in Tehran, Iran.

BACKGROUND: Considering the importance of high out-of-pocket (OOP) payment (OOPP), as a marker of health system performance, and affordability of medications in the elderly, this study was conducted to determine these issues. METHODS: In this cross-sectional study, prescriptions of patients aged 65 yr or older from 5 university-affiliated pharmacies in Tehran, Iran were evaluated from Jan to Mar 2014. Prescriptions were selected from four insurance organizations. We used the prescriptions data regarding patients' demographics and the prescribers as well as the sales data for OOP. Affordability was calculated by considering the daily salary of an unskilled worker. RESULTS: Totally, 1467 prescriptions were analyzed. Mean age of patients was 73.89(6.66) yr. Mean (SE) of reimbursable and OOPP of the prescriptions were 203820 (10831) and 230252 (10634) IRR (Iranian Rials) respectively (equivalent to 81.6 (4.33) and 92.17 (4.33) US$ respectively). Subspecialists imposed higher expenditures for patients and insurance organizations. Patients referred to the ophthalmologists paid less OOP. Nearly 50% of the total prescription costs was paid as OOP. The mean OOPP was averagely equal to 1.41(0.065) daily salary. These prescriptions were unaffordable for 36.2% of patients. CONCLUSION: The OOPP was higher than the insurance goal of 30% for outpatients in Iran. More than one-third of elderly patients could not afford their single prescription. Due to the health consequences of the unaffordability of medications, corrective actions are needed by the insurance organizations and the health system.

Adherence to medications, self-care activity, and HbA1c status among patients with type 2 diabetes living in an urban area of Iran.

BACKGROUND: Appropriate pharmacotherapy, self-care and adherence to medications are crucial to diabetes control. We aimed to study the diabetes care and glycemic control in patients with type two diabetes living in an urban area of Iran. METHODS: In this cross-sectional study, patients with type 2 diabetes who attended a referral university affiliated community pharmacy and an accredited pathobiology laboratory in the 17th district of Tehran were evaluated. Data including demographics, medical and drug history were collected. Self-care activity (Diabetes Self-care Activity Measurement Scale) and medication adherence (8-item Morisky Medication Adherence scale) were also assessed. After completing the questionnaires, the patients were referred to the laboratory for Hemoglobin A1c test. RESULTS: Three hundred forty-eight patients (60.3% females) were recruited. The mean (SD) of patients' age was 55.82 (12.72) and 75.3%of them were Illiterate or had primary education. Mean (SD) of Hemoglobin A1c levels was 8.39 (2.03) and 33% of patients had levels higher than 9%. Among study patients, 186 (53.4%) patients received monotherapy for diabetes type 2 and 200 (57.5%) patients had low adherence to medications. Physical activity, blood glucose self-monitoring and foot care were domains of self-care with the fewest practice. Re-using a pen or syringe needle more than once was reported by 83% of patients and mean (SD) time of re-using a pen needle was 9.11 (8.74). CONCLUSION: Poor glycemic control, low medication adherence, inadequate self-care activities, signals of inappropriate pharmacotherapy and inadequate medical visits and monitoring in the study patients highlight the importance of providing accessible and affordable health care services in the region. Moreover, educational needs of the patients should be considered especially in an area in which the majority of patients are old and illiterate and have low socioeconomic status.

High-dimensional additive hazards regression for oral squamous cell carcinoma using microarray data: a comparative study.

Microarray technology results in high-dimensional and low-sample size data sets. Therefore, fitting sparse models is substantial because only a small number of influential genes can reliably be identified. A number of variable selection approaches have been proposed for high-dimensional time-to-event data based on Cox proportional hazards where censoring is present. The present study applied three sparse variable selection techniques of Lasso, smoothly clipped absolute deviation and the smooth integration of counting, and absolute deviation for gene expression survival time data using the additive risk model which is adopted when the absolute effects of multiple predictors on the hazard function are of interest. The performances of used techniques were evaluated by time dependent ROC curve and bootstrap .632+ prediction error curves. The selected genes by all methods were highly significant (P < 0.001). The Lasso showed maximum median of area under ROC curve over time (0.95) and smoothly clipped absolute deviation showed the lowest prediction error (0.105). It was observed that the selected genes by all methods improved the prediction of purely clinical model indicating the valuable information containing in the microarray features. So it was concluded that used approaches can satisfactorily predict survival based on selected gene expression measurements.
