ABSTRACT
Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBCs 7.97 ×103mm-3, RBCs 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

ABSTRACT
Abstract Newcastle disease (ND) is an infectious, highly contagious and lethal disease of avian species. It is considered that ducks are natural reservoir or carrier for Newcastle disease virus (NDV) and are resistant against different strains of NDV. Current study was designed to evaluate the pathogenesis of Newcastle disease in domestic ducks through histopathology, immunohistochemistry (IHC) and serum biochemical changes. For this purpose, eighty ducks were reared for 42 days and divided in two groups A and B. Ducks in group A were challenged with (NDV) at rate of 0.1 ml of ELD50 (virus titer 107.32/100µl) on second week of age, whereas Group B was control negative. Splenomegaly, atrophy of thymus and necrotic lesion in kidney were observed on 9th day of post infection. Hepatic degeneration and mononuclear cell infiltration were noticed in proventriculus and intestine in challenged ducks. Viral antigen detected in lungs, intestine, proventriculus and lymphoid organs of infected ducks through IHC. Albumin and total protein values were significantly low in infected groups A as compared to control group B. ALT, AST, and ALP values were significantly high in infected group A. On 5th and 7th day of post infection oropharyngeal swabs were negative for NDV and cloacal swabs were positive for NDV through Reverse transcriptase polymerase chain reaction. It is concluded that ducks are susceptible to NDV and virulent strain of NDV caused disease in ducks.
Resumo A doença de Newcastle (DN) é uma doença infecciosa, altamente contagiosa e letal de espécies aviárias. Considera-se que os patos são reservatórios ou portadores naturais do vírus da doença de Newcastle (VDN) e são resistentes a diferentes cepas de VDN. O presente estudo foi desenvolvido para avaliar a patogênese da DN em patos domésticos por meio de histopatologia, imuno-histoquímica (IHQ) e alterações bioquímicas séricas. Para este propósito, 80 patos foram criados por 42 dias e divididos em dois grupos A e B. Os patos do grupo A foram submetidos ao VDN a uma taxa de 0,1 ml de ELD50 (título viral de 107,32 / 100 µl) na segunda semana de idade, enquanto o Grupo B foi controle negativo. Esplenomegalia, atrofia do timo e lesão necrótica no rim foram observadas no 9º dia pós-infecção. Degeneração hepática e infiltração de células mononucleares foram observadas no proventrículo e intestino em patos infectados. Antígeno viral foi detectado em pulmões, intestino, proventrículo e órgãos linfoides de patos infectados por IHQ. Os valores de albumina e proteína total foram significativamente baixos no grupo A infectado em comparação com o grupo B. Os valores de ALT, AST e ALP foram significativamente altos no grupo A. No 5º e no 7º dia após a infecção, os esfregaços orofaríngeos foram negativos para VDN, enquanto os esfregaços cloacais foram positivos para VDN por meio da reação em cadeia da polimerase via transcriptase reversa. Conclui-se que os patos são suscetíveis ao VDN e à cepa virulenta de VDN que causou doenças em patos.
ABSTRACT
Abstract Domestic donkey plays a key role as a draft animal in rural economy of Pakistan where its population is increasing every year. The complete mtDNA control region of forty randomly sampled donkeys was PCR- amplified and sequenced bi-directionally using specific primers. Distinct mtDNA haplotypes obtained in the current study (KY446001KY446011) were subjected to haplotype (h) and nucleotide diversity () measures using DnaS as well as to phylogenetic, Network, and AMOVA analyses. There were a total 27 polymorphic sites present within 11 unique mtDNA haplotypes from the studied 40 animals from different regions. Neighbor-joining network and median-joining network both illustrated the splitting of all these haplotypes into two well-defined Nubian and Somali lineages, confirming African maternal origin of Pakistani domestic donkey. Diversity parameters h (0.967± 0.037) and (0.02917± 0.00307) were found to reveal high levels of genetic diversity in Pakistani donkeys. AMOVA demonstrated only 1% of genetic differences between two mtDNA maternal lineages, pointing to lack of population substructure in Pakistani donkeys as is the case with worldwide domestic donkey population. Pakistani donkeys have African maternal origin and high levels of mtDNA diversity. High genetic diversity may be due to non-selective breeding and heteroplasmy. We herein provide the first report on mtDNA diversity of control region in Pakistani domestic donkey.
Resumo O burro doméstico possui um papel fundamental como animal de tração na economia rural do Paquistão, onde a população desse animal está aumentando a cada ano. A região de controle de mtDNA completa de 40 burros amostrados aleatoriamente foi ampliada por PCR e sequenciada bidirecionalmente por intermédio de primers específicos. Haplótipos distintos de mtDNA obtidos no estudo atual (KY446001 KY446011) foram submetidos a medidas de haplótipo (h) e diversidade de nucleotídeos () por meio de DnaS, bem como análises filogenéticas, de rede e AMOVA. Havia um total de 27 sítios polimórficos presentes em 11 haplótipos de mtDNA exclusivos dos 40 animais estudados de diferentes regiões. A rede de união de vizinhos e a rede de união mediana ilustram a divisão de todos esses haplótipos em duas linhagens núbias e somalis bem definidas, confirmando a origem materna africana do burro doméstico do Paquistão. Os parâmetros de diversidade h (0,967 ± 0,037) e (0,02917 ± 0,00307) revelaram altos níveis de diversidade genética em burros paquistaneses. AMOVA demonstrou apenas 1% de diferenças genéticas entre as duas linhagens maternas de mtDNA, apontando a falta de subestrutura populacional em burros paquistaneses, como é o caso da população mundial de burros domésticos. Os burros paquistaneses têm origem materna africana e altos níveis de diversidade de mtDNA. A alta diversidade genética pode ser por causa da reprodução não seletiva e de heteroplasmia. Aqui, fornecemos o primeiro relatório sobre a diversidade do mtDNA da região de controle em burros domésticos do Paquistão.
ABSTRACT
Abstract Aquatic insect fauna remains an important tool for bio indication of environmental disturbance, while maintaining a healthy aquatic system. The purpose of the study was to document and to identify the diversity and distribution patterns of aquatic insect, a highly ignored aspect from the Qatar. Following the standard procedures, the samples were collected from aquatic habitats during the period October 2015 to May 2017 on monthly basis. A total of 11,287 individuals, belonging to 6 orders were captured. Dipterans were the abundant with the percentages of 71.01 (n=8,015), while the lowest percentage was observed for Coleoptera 0.04 (n=05). Twelve insects families were identified, among these five were reported under Diptera, followed by Hemiptera (03), while Coleoptera, Tricoptera, Odonata, and Ephemeroptera were represented by single families. Among the selected localities, Dipterans were collected from 10 stations, followed by Hemiptera (9), Coleoptera (4), Odonota (4), Ephemeroptera (3) and Trichoptera (1) respectively. Among the water bodies samples, streams were the most preferred habitats (n=2,767), while drinking water pools were the least (27). Moreover, the highest Simpson diversity index of 1.48 and lowest of 0.47 was recorded for flooded sewage pool and plastic containers respectively, while the low evenness values were observed for ponds, and less than 1 Margalefs diversity values were seen for all habitats. This study documents the patterns of the diversity and distribution of aquatic insects, and provides a baseline for the future studies from Qatar.
Resumo A fauna aquática de insetos continua sendo uma ferramenta importante para a bioindicação de distúrbios ambientais, ao mesmo tempo em que mantém um sistema aquático saudável. O objetivo do estudo foi documentar e identificar a diversidade e os padrões de distribuição dos insetos aquáticos, um aspecto altamente ignorado no Catar. Seguindo os procedimentos padrão, as amostras foram coletadas em hábitats aquáticos durante o período de outubro de 2015 a maio de 2017, mensalmente. Um total de 11.287 indivíduos, pertencentes a seis ordens, foram capturados. Dípteros foram os mais abundantes, com as porcentagens de 71,01 (n = 8.015), enquanto a menor porcentagem foi observada para Coleópteros 0,04 (n = 05). Doze famílias de insetos foram identificadas, destas, cinco foram registradas sob Diptera, seguido por Hemiptera (03), enquanto Coleoptera, Tricoptera, Odonata e Ephemeroptera foram representados por famílias únicas. Dentre as localidades selecionadas, Dipterans foram coletados em 10 estações, seguidos por Hemiptera (9), Coleoptera (4), Odonota (4), Ephemeroptera (3) e Trichoptera (1), respectivamente. Entre as amostras de corpos d'água, os riachos foram os hábitats mais preferidos (n = 2.767), enquanto as piscinas de água potável foram os menos (27). Além disso, o maior índice de diversidade de Simpson de 1,48 e o menor de 0,47 foi registrado para piscina de esgoto inundada e recipientes de plástico, respectivamente, enquanto os valores de baixa uniformidade foram observados para lagoas e menos de 1 valores de diversidade de Margalef foram observados para todos os hábitats. Este estudo documenta os padrões de diversidade e distribuição de insetos aquáticos e fornece uma linha de base para os estudos futuros do Catar.
ABSTRACT
Abstract Objective This systematic review aims to describe the relationship between psychological resilience and mood disorders. Methods This is a systematic review and meta-analysis. The following databases were searched on November 6, 2020: PubMed, PsycINFO, and Embase. Results Twenty-three articles were included and the majority of the studies included (95.7%) showed that psychological resilience has a positive impact in mood disorders. Our meta-analysis showed that individuals with bipolar disorder presented significantly lower levels of psychological resilience compared to controls (standardized mean difference [SDM]: -0.99 [95% confidence interval {95%CI}: -1.13 to -0.85], p < 0.001). In addition, individuals with depression had significantly lower levels of psychological resilience compared to controls (SDM: -0.71 [95%CI -0.81 to -0.61], p < 0.001). Conclusion Our results showed that individuals with mood disorders are less resilient than individuals without mood disorders. Our findings reinforce the importance of investigating interventions that may help to improve psychological resilience considering its positive impact in the context of mood disorders.

Purpose: We aimed to determine whether Descemet抯 membrane (DM) scrolling occurs primarily along the vertical or horizontal axis and establish whether oval trephination along the axis of least scrolling can reduce the grade of the scroll. Methods: The longest limbus?to?limbus axis on 28 sclerocorneal discs was taken as the horizontal axis. The horizontal (n = 7) or (right angles to it) vertical (n = 6) axis was marked on DM before peeling it off. The direction and grade of scrolling was observed. Narrow strips (3�mm wide) were then cut along the two axes (n = 4 each) and the scrolling pattern was observed. Ellipses (7 � 9 mm) of DM were punched along the two axes (n = 6 each) and the scrolls graded. Immunofluorescent staining for elastin on horizontal and vertical tissue sections from three DM samples was performed. The intensity and thickness of elastin staining were measured. Results: Twenty?four (85.72%) DM samples showed scrolling along the horizontal axis, none showed scrolling along the vertical axis, and four (14.28%) samples showed a spiral scroll, regardless of which axis was marked (grade 3.7 and 3.6). Vertically oval discs showed significantly reduced scrolling (grade 1.2) compared to horizontally oval discs (grade 3.5). Narrow strips of DM showed a similar scrolling pattern. Immunohistology showed no difference in any of the parameters examined along the two axes or from the center to the periphery. Conclusion: DM scrolls primarily along the horizontal axis. Vertically oval DM samples show minimal scrolling, which can be an advantage in DMEK. Differential scrolling is not determined by the distribution of elastin.
ABSTRACT
Purpose: Glaucoma influences vision?related quality of life (VRQoL) of an individual in various ways. There are very limited studies on the Indian population and the northern part of India. Therefore, we conducted the present study to evaluate VRQoL in glaucoma patients as well as the association between the severity of glaucoma and VRQoL. Methods: An institution?based, cross?sectional, analytical study was conducted from August 2022 to October 2022 involving 190 participants (95 glaucoma patients and 95 controls). The glaucoma quality of life?15 (GQL?15) questionnaire was explained in their vernacular language by the interviewer. The scoring was given according to the validated scoring algorithm for the questionnaire. Results: Mean GQL score in the control group was 19.66 ± 5.5 and in glaucoma cases was 32.8 ± 10.2, whereas the mean score of mild glaucoma cases was 22.3 ± 4.83, moderate glaucoma cases was 36.3 ± 4.09, and severe glaucoma cases was 47.24 ± 3.03. Therefore, as the severity of glaucoma increases, the GQL score also increases, indicating poorer quality of life. Visual field loss was strongly positively correlated (correlation coefficient = 0.759, P < 0.01) with the GQL?15 score, while a weaker positive correlation was found with best corrected visual acuity (BCVA), cup disc ratio, and duration of treatment. Conclusion: Besides controlling or reducing intraocular pressure (IOP) to the target level, the goal of glaucoma treatment should be to provide an individual with good functional vision to maintain an acceptable quality of life. It would also help in providing patients with the best possible treatment, not only in terms of good vision but also in maintaining or improving their overall quality of life.
ABSTRACT
Background: Healthcare workers (HCWs) in India are facing physical and psychological pressure. The pandemic has significant psychological impacts. Hence, we wanted to assess the mental stress and social stress among HCWs during the second wave of COVID-19. Aim and Objectives: Assessment of the mental distress among HCWs of tertiary care level institution during second wave of COVID-19 with the following objectives: (1) To know the sociodemographic characteristics of the HCWs of tertiary care center and (2) to assess the psychological stress among healthcare workers of a tertiary health center. Material and Methods: It is a cross-sectional and observational study conducted in hospital setting, in a tertiary care setting. Data were collected from 196 HCWs of the institute. Institutional ethical clearance was taken before the study. Structured questionnaire included sociodemographic variables, work-related variables, and variables to assess social stress. We used hospital anxiety and depression scoring questionnaire to assess anxiety and depression. Data were collected through personal interviews and online through Google forms after taking informed consent. Descriptive statistics and Chi-square tests are used analyzed using Statistical Package for the Social Sciences Version 21 for Statistical analysis. Results: A total of 196 HCWs, 121 doctors, 74 nursing staff, and one ward staff participated in the study. Nursing staff were at higher risk for anxiety and depression, that is, 29% and 25% than others. Females were slightly more anxious (29%) and depressed (17%) than males. HCWs who are Muslim by religion were at more mental distress. Media exposure of more than 3 h had increased risk of mental distress. HCWs with other frontline COVID warrior as a partner were both anxious (40%) and depressed (20%). Anxiety (35%) was more among those who’s family members got COVID positive. About 25% of them faced social stigma, 55% of them faced issue of isolation with in the community, and 14% of them faced acts of violence which is unacceptable. Conclusions: Although its second wave HCWs are still having psychological distress which needs to be addressed. Social stress that they are facing is significant and is associated with higher anxiety and depression, which has to be taken seriously.
ABSTRACT
Background: Thymectomy has been identified as Constructive and active strategy for patients with Myasthenia gravis and thymic masses which have been done classically by Open Sternotomy technique and nowadays new Minimally invasive approaches have also been introduced. In this paper , Subxiphoid Uniportal VATS(Video Assis Method : ted Thoracoscopic Surgery) Thymectomy through a single port technique by utilizing the Subxiphoid approach has been discussed.

In the near future ,the Subxiphoid approach has the potential to become Conclusion: GOLD STANDARD for Thymectomy and various other conditions
ABSTRACT
Introduction: The medical curriculum, the medium of instruction and evaluation in India, is primarily English. While it has the advantage of preparing Indian medical graduates to represent and interact globally, it also translates into learning difficulties for a substantial population of Indian medical students. Hindi is the common language of communication among majority of the population in Uttar Pradesh.Madhya Pradesh Government in India has already started the option of pursuing the allopathic graduate medical course in Hindi. There is paucity of data regarding opinion of medical professionals about implementation of Medical Education in Hindi in Uttar Pradesh and nearby states. Objective: To assess the attitude and opinion of medical students and medical professionals towards using Hindi in Medical Education. Method: A cross-st stsectional web-based online survey was conducted between 1 December 2022 and 31 January 2023. Undergraduate medical students, interns, residents and faculty from medical colleges, hospitals of Uttar Pradesh and neighbouring states (Uttarakhand and Bihar) were contacted to participate in this survey using pretested structured questionnaire. Results: A total of 1606 participants responded and answered the questionnaire and 1575 responses were found complete and used in analysis.Most participants (52.8%) believed that Medical Education in Hindi would attract more students from Hindi backgrounds to join the medical field. Similarly, 58.9% of participants were of the opinion that Medical Education in Hindi would improve communication with patients. However, about half of the participants (49.5%) perceived teaching in Hindi as a hurdle in acquiring higher education. Conclusion: More than half of the participants thought that medical education in Hindi will attract more students from Hindi backgrounds to join the medical field. Similarly, Medical Education in Hindi was perceived to improve communication skills with patients, at least where Hindi is a vernacular language by majority of the participants.
ABSTRACT
Peripheral or generalized edema is an uncommon complication of insulin therapy in diabetes mellitus. The exact cause is yet not known. It is transient and self-limiting in nature. However, diuretics and aldosterone antagonists have been used in some cases. We report the case of a 14-year-old boy with newly diagnosed Type 1 diabetes who developed edema after the commencement of insulin therapy. Other causes of edema were excluded from the study. The child was managed conservatively and edema seemed to start decreasing after 72 h and completely disappear in 2 weeks.
ABSTRACT
@#Introduction: Burnout is a growing trend among medical students worldwide. The aim of this study was to determine the prevalence and factors associated with burnout among medical students at a public university in Malaysia. Methods: A cross-sectional study was conducted among 1st through 5th year medical students at a public university using a simple random sampling method in recruiting participants. In this study, The Maslach Burnout Inventory-General Survey for Student (MBI-SS) was used and burnout is defined as severely emotionally exhausted and severely depersonalised. Results: A total of 328 medical students were recruited with a with response rate of 88.6%. The burnout prevalence was 10.1%. Based on multivariate logistic regression, presence of smartphone addiction with adjusted (odds ratio (OR) 7.37, 95% confidence interval (CI) = 1.67, 32.49), course choice not based on personal interest or due to family pressure (OR 2.72, 95% CI = 1.08, 6.85) and the presence of family relationship problems (OR = 3.58, 95% CI = 1.27, 10.04) are more likely to be associated with burnout among the medical students. Conclusion: Our study has shown that every tenth medical students suffers from burnout. Medical students who are addicted to smartphone, have chosen medical course against individual interest or because of family pressure and have family relationship problems are at risk of getting burnout. Intervention is required to address this issue for the future well-being of medical students.
ABSTRACT
Abstract The current study was carried out to estimate the prevalence and diversity of ectoparasites in rock pigeons in different regions of Punjab, Pakistan. A total of 120 birds were captured from March 2017 to February 2019. The ectoparasites were collected by standard procedures and preserved in 70% ethanol containing one drop of glycerin. Data related to age, health status, sex, type of area, sampling location and season were collected using a standardized form. Ectoparasites were identified based on morphological characteristics by using identification keys. Ninety-six (80%) birds were infested with ectoparasites. A total of seven families and thirteen species of different ectoparasites were observed. Mainly, seven species of lice, two species of flies, one species of tick and three species of mites were recovered from infested birds. The female pigeons were more often infested (89.02%) than male pigeons (60.52%). The prevalence was found higher during summer (100%) as compared to other seasons. The infestation rate was higher in Industrial area (97.50%) as compared to other regions. The highest prevalence of ectoparasites (100%) was recorded from Sargodha district. There was significant (P < 0.05) variation among number of ectoparasites on wing, chest, tail and neck within age groups, seasons and ecological zones. The occurrence of parasites in relation to area, age, health status, sex and season were significant. The infestation rate of parasites in rock pigeon is high in different districts of Punjab. It is recommended that these wild birds infested with multiple species of ectoparasites could be the potential source of infestations in domesticated birds if they come in contact with them. The contact of domesticated birds should be prevented from wild birds to minimize the chance of cross species transmission of ectoparasites.
Resumo O presente estudo foi realizado para estimar a prevalência e diversidade de ectoparasitas em pombos-das-rochas em diferentes regiões de Punjab, Paquistão. Um total de 120 aves foram capturadas de março de 2017 a fevereiro de 2019. Os ectoparasitas foram coletados por procedimentos padrão e preservados em etanol 70% contendo uma gota de glicerina. Os dados relativos à idade, estado de saúde, sexo, tipo de área, local de amostragem e época do ano foram coletados em formulário padronizado. Os ectoparasitas foram identificados com base nas características morfológicas por meio de chaves de identificação. Noventa e seis (80%) aves estavam infestadas com ectoparasitas. Um total de sete famílias e treze espécies de diferentes ectoparasitas foram observados. Principalmente, sete espécies de piolhos, duas espécies de moscas, uma espécie de carrapato e três espécies de ácaros foram recuperadas de aves infestadas. Os pombos fêmeas foram infestados mais frequentemente (89,02%) do que os pombos machos (60,52%). A prevalência encontrada foi maior no verão (100%) em comparação com as outras estações. A taxa de infestação foi maior na área Industrial (97,50%) em relação às demais regiões. A maior prevalência de ectoparasitas (100%) foi registrada no distrito de Sargodha. Houve variação significativa (P <0,05) entre o número de ectoparasitas na asa, tórax, cauda e pescoço dentro das faixas etárias, estações do ano e zonas ecológicas. A ocorrência de parasitas em relação à área, idade, estado de saúde, sexo e estação do ano foi significativa. A taxa de infestação de parasitas em pombo-correio é alta em diferentes distritos de Punjab. Recomenda-se que essas aves selvagens infestadas com várias espécies de ectoparasitas possam ser a fonte potencial de infestações em aves domesticadas se entrarem em contato com elas. O contato de aves domesticadas deve ser evitado com aves selvagens para minimizar a chance de transmissão cruzada de ectoparasitas.

BACKGROUND@#Cardiovascular disease is a significant contributor to the disease burden in geriatric patients. Underlying systemic inflammation is thought to be the cause of age-related changes in the bone marrow and a major risk factor for atherosclerosis. The purpose of the study was to assess the accuracy of these hematological biomarkers in predicting 30-day mortality in older patients with acute coronary syndrome (ACS).@*METHODS@#This was a prospective observational study of 601 older adult patients (age > 60 years) with ACS who underwent percutaneous coronary intervention over two years (2017-2019). The relationship between baseline hematological parameters and mortality was assessed during the 30-day follow-up. Logistic regression analysis and receiver operating characteristic curve analysis were done to evaluate for diagnostic accuracy of various hematological parameters.@*RESULTS@#The mean age of presentation was 77 ± 17 years. The mean neutrophil-lymphocyte ratio (NLR) value was 5.07 ± 4.90 and the mean platelet-lymphocyte ratio (PLR) value was 108.65 ± 85.82. On univariate analysis, total leucocyte count [odds ratio (OR) = 0.85, P = 0.021], hematocrit (OR = 0.91, P = 0.018), NLR (OR = 1.10, P = 0.001) and PLR (OR = 1.05, P = 0.001) were associated with mortality. On receiver operating characteristic curve analysis, NLR predicted mortality with 68.1% and PLR with 65.7% accuracy. On multivariate analysis, NLR (OR = 1.096, 95% CI: 1.006-1.15, P = 0.035) was an independent predictor of 30-day mortality.@*CONCLUSIONS@#For the risk classification of all elderly ACS patients, we highly advise using NLR rather than the total white blood cell count.
ABSTRACT
Background@#A written asthma action plan (WAAP) is one of the treatment strategies to achieve good asthma control in children. @*Methods@#This randomized controlled trial was conducted to observe the effect of WAAP on asthma control and quality of life using the Asthma Control Questionnaire and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) at baseline and after 3 months. A repeated measure analysis of variance was used to analyze the mean score difference between the two groups. @*Results@#There was no significant difference in mean score for asthma control at baseline between groups (F[degree of freedom (df)]=1.17 [1, 119], P=0.282). However, at 3 months, a significant difference in mean scores between groups was observed (F[df]=7.32 [1, 119], P=0.008). The mean±standard deviation (SD) scores in the intervention and control groups were 0.96±0.53 and 1.21±0.49, respectively. For the analysis of the PAQLQ, no significant difference was observed in the mean score for the quality of life baseline in both groups. There were significant mean score changes for the quality of life (F[df]=10.9 [1, 119], P=0.001) at 3 months follow-up, where those in the intervention group scored a mean±SD score of 6.19±0.45, and those in the control group scored 5.94±0.38. A time-group interaction analysis using repeated-measures analysis of variance showed significant differences in mean score changes (F[df]=5.03 [1, 116], P=0.027) and (F[df]=11.55 [1, 116], P=0.001) where a lower mean score was observed in the intervention group, indicating better asthma control and quality of life, respectively. A significant (P<0.001) negative Pearson correlation between asthma control and quality of life (-0.65) indicated a moderate correlation. @*Conclusion@#WAAP, along with standard asthma treatment, improves asthma care.
