Health-related quality of life in persons with haemophilia in Afghanistan.

INTRODUCTION: Haemophilia is the most common severe congenital bleeding disorder and can significantly influence patients' quality of life. The health-related quality of life (HRQoL) is a multi-dimensional concept that assess effect of different aspects of health status, including physical, mental, and social domains. Identification of the factors affecting the HRQoL of Persons with Haemophilia (PWH) can guide health care system to better management of patients. AIM: The aim of the present study is to evaluate HRQoL in PWH in Afghanistan. METHODS: This cross-sectional study was conducted on 100 PWH in Kabul City, Afghanistan. Data were collected using 36-Item-Short-Form Health Survey (SF-36) questionnaire and analysed using correlation coefficients and regression analysis. RESULTS: The mean scores for the SF-36 questionnaire 8 domains range from 33 ± 38.3 to 58.15 ± 20.5. The highest mean value belongs to physical function (PF) (58.15), whereas the lowest is related to restriction of activities due to emotional problems (RE) (33.00). A significant association (p < .005) was observed between all domains of SF-36 and patients' age except for PF (p = .055) and general health (GH) (p = .75). A significant association was also observed between all HRQoL domains and the severity of haemophilia (p < .001). The severity of haemophilia was the significant predictor for Physical Component Summary (PCS) and Mental Component Summary (MCS) (p < .001). CONCLUSION: Due to the reduced HRQoL in Afghan PWH, special attention by health care system should be paid to improve patients' quality of life.

ATLAS: An Adaptive Transfer Learning Based Pain Assessment System: A Real Life Unsupervised Pain Assessment Solution.

Undertreatment or overtreatment of pain will cause severe consequences physiologically and psychologically. Thus, researchers have made great efforts to develop automatic pain assessment approaches based on physiological signals using machine learning techniques. However, state-of-art research mainly focuses on verifying the hypothesis that physiological signals can be used to assess pain. The critical assumption of these studies is that training data and testing data have the same distribution. However, this assumption may not hold in reallife scenarios, for instance, the adoption of machine learning model by a new patient. Such real-life scenarios in which user's data is unlabeled is largely neglected in literature. This study compensates for the rift by proposing an adaptive transfer learning based pain assessment system (ATLAS), a novel adaptive learning system based on the transfer learning algorithm Transfer Components Analysis (TCA) to minimize the distance between training data and unlabeled testing data. Experiments were conducted on BioVid database, and the results showed our approach outperforms three existing traditional machine learning-based approaches and achieves an accuracy just 2.0% below the accuracy with labeled data.

Prevalence and determinants of self-medication with antibiotics among general population in Afghanistan.

OBJECTIVE: Self-medication with antibiotics (SMA) is a common cause of antibiotic resistance, a major public health problem. This research aimed to identify the prevalence of SMA and explore reasons for practicing SMA among people living in Kabul, Afghanistan. METHODS: A community-based cross-sectional study was conducted from May to November 2017 in 12 community pharmacies operating across Kabul, Afghanistan. Multivariable logistic regression was conducted to identify the factors associated with the use of SMA. RESULTS: Out of 385 participants, 282 (73.2%) practiced SMA during the last year. Overall, 241 (62.6%) were 'very concerned' about the use of SMA, and 156 (40.5%) highlighted it is bad to practice SMA. The top three antibiotics used for self-medication were penicillin (ATC class: J01C), metronidazole (ATC: P01AB01), and ceftriaxone (ATC: J01DD04). Economic problems, lack of time to visit doctors, and ease of use were cited as the main reasons for practicing SMA. Furthermore, female participants were less likely to practice SMA compared to male counterparts. CONCLUSION: While efforts should be directed to enforce strict drug regulations system and awareness programs, priority should be given to provide accessible, affordable, and quality health care services to increase citizen's compliance to appropriate drug prescriptions.

Assessment of Knowledge, Attitude, and Practice of Health-Care Workers Towards Hepatitis B Virus Prevention in Kabul, Afghanistan.

BACKGROUND: Hepatitis B virus (HBV) infection is a serious public health issue around the world. Health care workers (HCWs) are at high risk of HBV infection because they have direct contact with HBV infected blood and body fluids in their work. OBJECTIVE: The purpose of this study was to evaluate the knowledge, attitude, and practice (KAP) of HCWs towards hepatitis B infection in Kabul, Afghanistan. METHODS: This cross-sectional study was conducted on 502 HCWs, between November 2018 and January 2019 by a simple random sampling method. The data was collected through a self-administered structured questionnaire. Using this questionnaire, demographic characteristics and KAP of HCWs was assessed. In addition, descriptive and inferential analyses was conducted on the collected data using SPSS 16 (SPSS Inc., Chicago, IL, USA). RESULTS: The overall KAP scores of HCWs were found to be 86.58%, 34.73%, and 61.22%, respectively. Most of the participants correctly recognized the HBV infection. Among the participants, only 77.45% had undergone screening for HBV, and 56.37% had received HBV vaccine (p < 0.0001). Moreover, only 6.77% had completed the three doses of vaccination for HBV. Among the HCWs, the group with higher education level had better knowledge than the group with lower education level. However, the attitude of most of the participants towards HBV prevention was found to be inadequate (53.98%). CONCLUSION: This study shows that HCWs in Kabul, Afghanistan are at high risk of HBV infection due to low vaccination coverage and inadequate infection control. Therefore, we strongly encourage providing an accessible and compulsory vaccination program for all HCWs to improve their attitude and awareness towards HBV infection and to achieve effective infection control.

Community Behavioral and Perceived Responses in the COVID-19 Outbreak in Afghanistan: A Cross-Sectional Study.

OBJECTIVE: Community responses are important for the management of early-phase outbreaks of coronavirus disease 2019 (COVID-19). Perceived susceptibility and severity are considered key elements that motivate people to adopt nonpharmaceutical interventions. This study aimed to (i) explore perceived susceptibility and severity of the COVID-19 pandemic, (ii) examine the practice of nonpharmaceutical interventions, and (iii) assess the potential association of perceived COVID-19 susceptibility and severity with the practice of nonpharmaceutical interventions among people living in Afghanistan. METHODS: A cross-sectional design was used, using online surveys disseminated from April to May 2020. Convenience sampling was used to recruit the participants of this study. The previously developed scales were used to assess the participants' demographic information, perceived risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and perceived severity of COVID-19. Multivariate analyses were conducted to assess the potential association of perceived COVID-19 susceptibility and severity with the practice of nonpharmaceutical interventions. RESULTS: The Internet was the main source for obtaining COVID-19 information among participants in this study. While 45.8% of the participants believed it was "very unlikely" for them to get infected with COVID-19, 76.7% perceived COVID-19 as a severe disease. Similarly, 37.5% believed the chance of being cured if infected with COVID-19 is "unlikely/very unlikely." The majority of participants (95.6%) perceived their health to be in "good" and "very good" status. Overall, 74.2% mentioned that they stopped visiting public places, 49.7% started using gloves, and 70.4% started wearing a mask. Participants who believed they have a low probability of survival if infected with COVID-19 were more likely to wear masks and practice hand washing. CONCLUSIONS: It appears that communities' psychological and behavioral responses were affected by the early phase of the COVID-19 pandemic in Afghanistan, especially among young Internet users. The findings gained from a timely behavioral assessment of the community might be useful to develop interventions and risk communication strategies in epidemics within and beyond COVID-19.

Evaluation of endothelial function in exogenous subclinical hyperthyroidism and the effect of treatment.

BACKGROUND: Subclinical hyperthyroidism (SHy) is a widespread condition in which cardiovascular manifestations are frequently occur, but there is still a debate about the vascular responsiveness in it. Measuring flow-mediated dilation (FMD) and intimae-media thickness (IMT) are used to evaluate endothelial function in these patients. MATERIALS AND METHODS: Twenty-five patients with a diagnosis of exogenous SHy and 25 full matched healthy subjects were enrolled. At first FMD of brachial artery and IMT of common carotid artery were obtained from all the participants. In the second phase, in the second phase of study, the dosage of levothyroxine was reduced at least 25% of prior dosage, and this was continued until thyroid stimulating hormone became normal range. Measuring FMD and IMT was repeated after this intervention in the case group. RESULTS: The mean age of case and control groups were 38.48 ± 12.05 and 36.72 ± 11.15 years, respectively. The mean of FMD in healthy people was dramatically higher than the subclinical hyperthyroid patients (P < 0.001) but no statistically significant difference was found for IMT (P = 0.459). After intervention in the case group, FMD was meaningfully increased (P < 0.001) but IMT of common carotid artery was not considerably changed (P = 0.491). CONCLUSIONS: This study demonstrated that FMD decreased in exogenous subclinical hyperthyroid patients which could be partially restored by treatment. These findings suggest that treatment of subclinical hyperthyroid state could improve endothelial dysfunction and at the end decreased the cardiovascular complications.

Optimization of photocatalytic degradation of real textile dye house wastewater by response surface methodology.

This study evaluates the advanced oxidation process for decolorization of real textile dyeing wastewater containing azo and disperse dye by TiO2 and UV radiation. Among effective parameters on the photocatalytic process, effects of three operational parameters (TiO2 concentration, initial pH and aeration flow rate) were examined with response surface methodology. The F-value (136.75) and p-value <0.0001 imply that the model is significant. The 'Pred R-Squared' of 0.95 is in reasonable agreement with the 'Adj R-Squared' of 0.98, which confirms the adaptability of this model. From the quadratic models developed for degradation and subsequent analysis of variance (ANOVA) test using Design Expert software, the concentration of catalyst was found to be the most influential factor, while all the other factors were also significant. To achieve maximum dye removal, optimum conditions were found at TiO2 concentration of 3 g L-1, initial pH of 7 and aeration flow rate of 1.50 L min-1. Under the conditions stated, the percentages of dye and chemical oxygen demand removal were 98.50% and 91.50%, respectively. Furthermore, the mineralization test showed that total organic compounds removal was 91.50% during optimum conditions.

Effect of leptin receptor Q223R polymorphism on breast cancer risk.

OBJECTIVES: Leptin receptor (LEPR) is a member of the class I cytokine receptor super-family that is known implicated in the initiation and progression of breast cancer. We have investigated the effect of Q223R polymorphism on the breast cancer susceptibly in a sample of Iranian subjects. MATERIALS AND METHODS: We utilized a polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP) method to investigate the association of LEPR Q223R polymorphism with breast cancer risk in a case control study consisting of 100 breast cancer cases and 100 controls without breast cancer. Serum levels of leptin and soluble leptin receptor (sOB-R) were measured by ELISA method. RESULTS: The genotype (QQ, QR, and RR) distributions were 25, 56, and 19 % in breast cancer cases and 54, 40, and 6% in controls, respectively. The frequency of 223 RR genotype was significantly elevated in breast cancer cases as compared to controls (χ(2)= 20.072, P<0.001). Similar significance differences were also found in allele frequencies for Q and R between two groups (χ(2)= 19.027, P< 0.001). Additionally, there were significant association between Q223R genotypes and breast cancer risk; homozygotes for RR genotype (OR= 6.840; 95% confidence interval [CI] = 2.434-19.218), heterozygotes for QR (OR=3.024; 95% CI = 1.620-5.644, P = 0.001), and QR+RR genotype (OR= 3.522; 95% CI = 1.934-6.414, P < 0.001), respectively. CONCLUSION: Our results showed that the LEPR Q223R polymorphism is associated with increased breast cancer risk as well as tumor grade in a sample of Iranian subjects.

Strengthening the skin with topical delivery of keratinocyte growth factor-1 using a novel DNA plasmid.

Fragile skin, susceptible to decubitus ulcers and incidental trauma, is a problem particularly for the elderly and for those with spinal cord injury. Here, we present a simple approach to strengthen the skin by the topical delivery of keratinocyte growth factor-1 (KGF-1) DNA. In initial feasibility studies with the novel minimalized, antibiotic-free DNA expression vector, NTC8385-VA1, the reporter genes luciferase and enhanced green fluorescent protein were delivered. Transfection was documented when luciferase expression significantly increased after transfection. Microscopic imaging of enhanced green fluorescent protein-transfected skin showed green fluorescence in hair follicles, hair shafts, and dermal and superficial epithelial cells. With KGF-1 transfection, KGF-1 mRNA level and protein production were documented with quantitative reverse transcriptase-polymerase chain reaction and immunohistochemistry, respectively. Epithelial thickness of the transfected skin in the KGF group was significantly increased compared with the control vector group (26 ± 2 versus 16 ± 4 µm) at 48 hours (P = 0.045). Dermal thickness tended to be increased in the KGF group (255 ± 36 versus 162 ± 16 µm) at 120 hours (P = 0.057). Biomechanical assessment showed that the KGF-1-treated skin was significantly stronger than control vector-transfected skin. These findings indicate that topically delivered KGF-1 DNA plasmid can increase epithelial thickness and strength, demonstrating the potential of this approach to restore compromised skin.

Bacterial meningitis: a new risk factor.

BACKGROUND: The purpose of this study is to discuss a possible new risk factor for the bacterial meningitis. METHODS: Cerebrospinal fluid collected from 270 patients was assayed. An enzyme immunosorbent assay for the detection of Staphylococcal enterotoxins A to E was used. RESULTS: The results indicated that the frequency of Coagulase Negative Staphylococci (CoNS) was 35 (20.46%). An important finding of this research was that the CoNS isolates produced enterotoxin C and D or enterotoxin C and E. CONCLUSIONS: This is the first report of enterotoxin-producing Coagulase Negative Staphylococci isolated from CSF patients. Therefore, these enterotoxins probably act as risk factors in the bacterial invasion into central nervous system.
