ABSTRACT

Abstract Introduction Radiotherapy provides excellent outcome in early stage glottic cancer; however, the optimal radiotherapy dose fractionation remains unknown. Objective To investigate the outcome of patients with T2N0M0 treated with either hypofractionated (HypoFxn) or conventionally fractionated radical (ConFxn) radiotherapy. Methods According to our institutional protocol, patients with T2N0M0 glottic cancer can be treated either with ConfFxn or HypoFxn radiotherapy, as per clinician's and patient's choice, following shared decision making discussing the advantages and disadvantages of both modalities. A total of 77 patients with T2N0M0 squamous cell carcinoma of glottis treated with either HypoFxn 55Gy in 20 fractions (n = 19) or ConFxn 63 to 65Gy in 30 fractions (n = 58) were included. Results With median follow-up of 3.4 years, there was no significant difference in disease-free survival (median: HypoFxn = 65.2 months, and ConFxn = 75.3 months; p = 0.874), local recurrence free survival rates (median: HypoFxn = 78.8 months vs. ConFxn = 81.2 months; p = 0.274), and overall survival (median: HypoFxn = 65.9 months vs. ConFxn = 67.7 months; p = 0.532). Elective neck irradiation was given to 43 patients, all in the ConFxn group, and this was associated with poorer local control (p = 0.027). The use of radiotherapy modality, three-dimensional conformal radiotherapy (3DRT) versus intensity modulated radiotherapy (IMRT), was not a prognostic factor (p = 0.36). In the HypoFxn group, grade III acute dysphagia requiring nasogastric tube was 16%, compared with 25% in the ConFxn group (p = 0.446). Conclusion HypoFxn radiotherapy provides a comparable treatment outcome with acceptable toxicity. The addition of prophylactic irradiation of the neck lymph nodes has no impact on regional control.

ABSTRACT

Abstract: Olive is grown in semi-arid climatic conditions; however, little is known about mineral changes in olive plant and nutrient requirements during the production period. Hence, the current study was conducted under Pothwar agro-climatic conditions in order to select appropriate stage of macronutrients (N, P, K) application in relation to soil and leaf nutritional status during 2017 and 2018 growing seasons. Soil and leaf analysis were performed at four different phenological stages (i.e. flowering, fruit setting, fruit enlargement and fruit maturity stages). The results revealed that the assessed macronutrient in leaf and soil varied significantly among varieties, phenological stages and growing year. The results revealed also that nitrogen level was found to decrease from fruit set (1.56%) to fruit enlargement stage (1.47%). Leaf and soil N, P and K contents were found higher before the flowering (stage 1) and depleted after fruit harvesting (stage 4), regardless of olive varieties. However, high yielding varieties showed lower nutrients after fruit harvesting (stage 4). Therefore, N content in leaf and soil gradually decreased during fruit growth and development. Whereas, K content in leaf and soil sharply declined from fruit maturity to fruit ripening stage. Overall, the trend of nutrient depletion showed that plants need phosphorus for fruit setting, nitrogen before and after fruit setting, and potash after pit hardening or at oil accumulation stages.

ABSTRACT

Introduction: Having a good health-related quality of life (HRQoL) is important to ensure good job performance. However, it is subjective and it cannot be measured easily. This study aimed to evaluate HRQoL among universityhealthcare academics in public andprivate universities.Method:In this study,a stratified random sampling approach was employed. The strata were created based on departments in the universities. Arandom sample from each stratum was taken in a number proportional to the stratum's size when compared to the overall target population. A validated questionnaire comprising two sections was administered online to collect the data. Descriptive and inferential statistical analysis (Mann-Whitney U test and Kruskal Wallis H test) were applied using SPSS version 22.Results: Out of all the total 130 respondents, 57 (43.8%) were from a private university and the other 73 (56.2%) were from a public university. There were 61 (46.9%) male respondents and 69 (53.1%) female respondents. HRQoL according to the studied domains of the DUKE health profile was associated with various demographic and socioeconomic variables such as type of institution, department/faculty, age, gender, number of children,and years of experience.Conclusion:The demographic and socioeconomic variables were strongly associated with the HRQoL among university healthcare academics.

ABSTRACT

Introduction: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) appears to be the main reason for hospitalization among chronic obstructive pulmonary disease (COPD) patients. This study aimed to evaluate the substantial economic burden of COPD in terms of out-of-pocket costs (OOPCs) among COPD patients. Methods: This study consisted of 67 consenting patients with AECOPD. A cross-sectional study was performed via convenience sampling. Data were gathered based on per episode of exacerbation and the calculation of OOPCs was done based on direct and indirectcosts. Results:This study showed that the mean length of hospital stay for four severity levels (according to GOLD guidelines) was 3.4, 7.2, 10.3 and 14.1 days, respectively. The mean OOPCs per episode of exacerbation according to the severity level were 139.1, 153.3, 171.4 and 365.8 USD, respectively Conclusion: Impacts of OOPCs regarding AECOPD episodes on healthcare resources are worthy of attention. Cost estimation from patients’ perspective especially OOPCs estimation is important in decision and policy-making to improve healthcare states of a population

ABSTRACT

Introduction:During Hajj and Umrah season, asthma-related acute admissions produce the enormous burden on healthcare facilities and causes delay in admissions for more severe cases, e.g. myocardial infarction,cardiac failureand severe trauma cases. Therefore, the snapshot of asthma-related admissions during the Hajj and Umrah season was determined by asthma-related admissions and medication use and economic burden during Hajj and Umrah pilgrimage season. Methodology:All asthma-related admissions during the month of Ramadan (fasting month) and Hajj pilgrimage were assessed from patients’data retrospectively. The convenience sampling strategy was used to retrievestudy variables. Statistical Package for Social Science (SPSS) Version 22.0 was used to analyze the data.Results:A total of 271 patients were selected as per inclusion criteria, the majority of them were males 153 (56.5%), while most of them were Saudi 70 (35.8%) and Egyptians 86 (31.7%). During hospitalization, the common treatment for acute exacerbations was inhaled corticosteroids 224 (86.3%), IV corticosteroids 129 (47.6%), Inhaled short-acting beta-agonists 244 (90%) and inhaled bronchodilators (ipratropium bromide) 237(87.5 5%). Conclusion:This periodic mapping of asthma-related admissions and its management during these massive gathering events is indeed a significant effort to explore issues of acute asthma exacerbations management and to provide information to plan for future interventions and policies.

ABSTRACT

Introduction:Chronic obstructive pulmonary disease (COPD) imparts a substantial economic burden on an individual and society. Exacerbation of COPD (ECOPD) is the primary cost driver for this burden as it usually associated with hospital admissions of COPD patients. The present study aimed to determine the direct costs of acute ECOPD among COPD patients.Methods:A total of 90 eligible patients with acute ECOPD who were admitted to the hospital were involved in this study. A convenient sampling technique was used during data collection. Cost data were collected according to the expenditures and existing information. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 23.0. TheSpearman's rank test was used to observe the differences (correlations) between the Govt perspective and the patient perspective.Results:The direct costs per episode of acute ECOPD were determined according to the Anthonisen criteria for evaluating acute ECOPD. The mean direct costs for severity III, severity I and severity I were 89.1, 134.8 and 178.2 USD respectively. The cost of acute ECOPD was positively associated with disease severity, length of hospital stay and the number of co-morbidities.Conclusion:Acute ECOPD patients consume a considerable amount of healthcare resources and pose a significant economic burden on the government

ABSTRACT

Introduction:The role of community pharmacists (CPs) has kept on changing. Due to the evolving role of CPs, it is important to know its impact on the health-related quality of life (HRQoL) among CPs. Besides, the literature on the HRQoL of CPs is not being enriched, there is an urge to carry out a study to evaluate the HRQoL among CPs. This study aimed to examine the association between the socio-demographic factors and the HRQoLamongCPs. Methodology: A set of questions related to the HRQoL has been adopted from a pre-validated questionnaire, the Duke Health Profile and contextualized it to measure study outcomes. The target population in this study was the registered CPs that were practicing. The site of the study included all the chain and independent pharmacies. Statistical Package for Social Science (SPSS)version 22.0 was used to analyze the data and the significance level was set at p≤0.05. Variousdomains of the Duke Health Profile (DHP) were calculated using the provided formula Results: A total of 172 respondents were included in this study. Several HRQoL domains were significantly associated with socio-demographic factors. The univariate analysis illustrated that mental and general healthstatehad significant associations with age, practice setting was significantly associated with the mental health state, the salary was significantly associated with self-esteem and mental health was significantly associated with length of service and practice setting. Dysfunction dimensions of anxiety, anxiety-depression, and pain were significantly associated withgender. Conclusion: Gender, age, length of service, salary and practice setting were the risk factors for HRQoL among CPs

ABSTRACT

Aims: This study aimed to assess the current levels of job and workplace satisfactionamong community pharmacists (CPs) and to explore the factors that can affect their job and workplace satisfaction. Methods: A self-administered research tool (questionnaire) was developed based on previously published literature. After its reliability and validity measurements, the questionnaire was distributed to the target population and data was collected. Data wereentered into Statistical Package for Social Science (SPSS) ver. 22.0 and analyzed using descriptive statistics, chi-square,and multiple regression analysis. The level of significance (α) was set at 0.05.Results: CPs reported high satisfaction (76.7%) concerning their jobs. Only 23.3% of them were not satisfied with their current job. Univariate analysis showed that job and workplace satisfactionamong CPs was not significantly associated with gender, age, length of service, position and salary. However, the univariate analysis demonstrated a significant difference between practice settings and job and workplace satisfactionwith p= 0.013. Among the respondents, those who worked in the chain pharmacies (83.7%) expressed greater job and workplace satisfaction, which is 16% higher than those working in independent pharmacies (67.6%). Therefore, practice setting was shown as the predictor of job and workplace satisfactionamong CPs by using multiple regression analysis. Conclusion: Overall, CPswere relatively satisfied with their current job. Our results had reinforced previous studies that reported that practice settings can affect pharmacists’ job and workplace satisfaction.

ABSTRACT

Introduction:Medication errors caused devastating consequences affecting both the healthcare system and the patient’s trust. Junior doctors, pharmacists, and nurses are prone to make these mistakes. Thus, this study served a purpose to evaluate the pharmacological knowledge of the healthcare students (HCSs) i.e. pharmacy, medical, and nursing studentsthroughdetecting errors in the prescriptions, as this will reflect their performance once they come in real practice.Methodology:A cross-sectional, descriptive study was conducted using a validated research tool consisting ofdemographics attributes (gender, race, duration of pre-university and age) as well as three prescriptions. The research tool was distributed to final year HCSs. Demographic data of the respondents were required to investigate the contributing factors in medication errors’ identification. Data obtained were analyzed using descriptive and inferential statistics by using SPSS ver. 22.Results: 197 students responded to this study. Findings show that pharmacy students yield high percentages compared to medical and nursing students in identifying errors in the prescriptions. 91.1% of pharmacy students were successful in recognizing the errors in prescription 1, 55.0% in prescription 2 whereas 96.2% in prescription 3. There wasa significantassociation betweenthe age of the respondents and their ability in identifying the errors (p=0.012). No significant relationship was observed between race, gender and duration of pre-university in identifying the mistakes in the prescriptions (p>0.05).Conclusion: Pharmacy students had the highest percentage ofmedication error identification rates probably in light of the pharmacy curriculum focuses mainlyon pharmacology and therapeutic monitoring. This study portrays the importance of additional clinical training in undergraduate programs to enhance student’s pharmacological knowledge and their attitude towards patient safety practices

ABSTRACT

Formation of stones in the gall bladder is known as cholelithiasis. About 10% to 20% of Western population are suffering from gall stones and this percentage is increasing day by day. Biochemically gall stones are classified into black pigment stones, brown pigment stones and cholesterol stones. Gall stones can be anatomically located at two possible sites; in the gall bladder known as cholelithiasis and in the common bile duct known as choledocholithiasis. Gall stones may present with symptoms known as symptomatic gallstones or without symptoms known as asymptomatic gallstones. The major causes of gallstones are high cholesterol diet, low bile salt levels, decreased gall bladder motility etc. Obesity, female gender, family history, rapid weight loss and vitamin B12 or folic acid deficiency are considered as important risk factors in the development of gall stones. The clinical presentations include acute cholecystitis and febrile illness with pain and tenderness in the right upper quadrant (Murphy sign). Generalized body weakness and weight loss are considered as generalized symptoms of gallstones. The complications include cholangitis, empyema of gall bladder, pancreatitis, abscess formation, porcelain gall bladder and gall bladder perforation. The differential diagnosis of gall stones is carried out based on endoscopy, ALT and AST serum levels. Non-surgical treatment for gall stones is oral dissolution therapy. The standard surgical treatment for gall stones is cholecystectomy.

ABSTRACT

The aggravating threat for today's agriculture is provision of food security to ever-escalating population utilizing scarce resources. Water scarcity is restraining humans to produce more from drops of water in place of gallons. Root is present at soil-plant interface and is main water extractor for plant. Its growth pattern varies as soil moisture conditions fluctuates. Present pot study consisting of two factors i.e. organic substrates (Farm manure, Poultry Manure and Molasses) and different water stress levels {50, 75, 100 and 125% of available water contents (AWCs)} using maize as test crop to assess their impact on different growth parameters (especially root growth). The experiment was conducted using completely randomized design CRD under factorial arrangement. Root length (44.5 cm), root fresh & dry biomass (71.1 g and 24.3 g, respectively), root diameter (1.73 mm), root volume (0.24 cm3) and root length density (7.4 x 10-3 cm cm-3) were observed in farm manure treated pots at 75% AWC that was statistically indistinguishable from all other treatments at same water level and 100% water availability but eloquently greater than plants of all treatments at 50% and 125% available water contents. Shoot length, dry and fresh weights were observed greater in plants having 100% available moistures. They were statistically at par with 75% water treated plants. Comparing treatments for all the parameters in multivariate cluster analysis it was concluded that 75% available water contents produce almost similar to 100% along with the benefit of water security.


A ameaça agravante para a agricultura atual é a provisão de segurança alimentar para populações cada vez maiores, utilizando recursos escassos. A escassez de água está restringindo os seres humanos a produzir mais a partir de gotas de água no lugar de galões. A raiz está presente na interface solo-planta e é o principal extrator de água para a planta. Seu padrão de crescimento varia conforme as condições de umidade do solo flutuam. O presente estudo em vaso é constituído por dois fatores, ou seja, substratos orgânicos (esterco bovino, esterco de aves e melaço) e diferentes níveis de stress hídrico {50, 75, 100 e 125% do teor de água disponível (AWCs)} utilizando milho como cultura de teste para avaliar o seu impacto em diferentes parâmetros de crescimento (especialmente crescimento de raiz). O experimento foi conduzido utilizando delineamento experimental inteiramente casualizado, em arranjo fatorial. Raiz radicular (44,5 cm), biomassa seca e fresca da raiz (71,1 ge 24,3 g, respectivamente), diâmetro radicular (1,73 mm), volume radicular (0,24 cm3) e densidade radicular (7,4 x 10-3 cm cm-3) foram observados em vasos tratados com esterco de fazenda a 75% AWC que foi estatisticamente indistinguível de todos os outros tratamentos no mesmo nível de água e 100% de disponibilidade de água, mas eloqüentemente maior que plantas de todos os tratamentos a 50% e 125% de conteúdo de água disponível. O comprimento do rebento, peso seco e fresco foram maiores nas plantas com 100% de umidade disponível. Eles foram estatisticamente equivalentes a 75% de plantas tratadas com água. Comparando os tratamentos para todos os parâmetros na análise multivariada de clusters, concluiu-se que 75% do conteúdo de água disponível produz quase o mesmo que 100%, juntamente com o benefício da segurança hídrica.

ABSTRACT

Restoration, preservation and sustainability of agricultural resources including soil demands biologically and economically viable farming practices. For boosting physico-chemical properties of soil from 2012 to 2015, three legumes including cowpea, cluster bean and soybean were intercropped with sorghum in 40-60, 75-25 and 100-100 seed blending ratios, while pure stand of sorghum was kept for comparison. Correlation studies were also conducted to determine linear or inverse relationship between physiological and agronomic attributes with green forage yield of sorghum. Results revealed that intercropping systems were not effective in significantly improving the physical properties of soil, however soybean and sorghum mixed seeded crop in 100-100 seed ratio resulted in the highest total and available nitrogen especially during last two years of the study and it was followed by mixed seeded crop of cluster bean and sorghum (100-100 seed ratio), while pure stand of sorghum appeared to be the most exhaustive farming system. Correlation analysis depicted a linear relationship between all agronomic attributes (seedling count, plant population at harvest, plant height, stem diameter, number of leaves and leaf area per plant, fresh and dry weights per plant) and physiological growth parameters (leaf area index and leaf area duration, crop growth rate and net assimilation rate) with forage yield of sorghum. Thus, legumes inclusion was found to be effective in restoring soil fertility, while long term legumes inclusion by following rotation may be suggested.


A restauração, a preservação e a sustentabilidade dos recursos agrícolas, incluindo o solo, exigem práticas agrícolas biologicamente e economicamente viáveis. Para aumentar as propriedades físico-químicas do solo de 2012 a 2015, três leguminosas, incluindo feijão-fradinho, guar e soja, foram consorciadas com sorgo nas proporções de mistura de 40-60, 75-25 e 100-100, enquanto que o sorgo puro foi mantido por comparação. Estudos de correlação também foram conduzidos para determinar a relação linear ou inversa entre atributos fisiológicos e agronômicos com a produtividade de forragem verde do sorgo. Os resultados revelaram que os sistemas consorciados não foram eficazes em afetar significativamente as propriedades físicas do solo, no entanto, soja e sorgo misturados na proporção de sementes 100-100 resultou no maior nitrogênio total e nitrogênio disponível, especialmente durante os últimos dois anos do estudo e foi seguido do plantio de sementes mistas de guar e sorgo (100-100 rácio de semente), enquanto a monocultura de sorgo parecia ser o sistema de agricultura mais exaustivo. A análise de regressão mostrou uma correlação linear entre todos os atributos agronômicos (contagem de plântulas, população de plantas na colheita, altura de planta, diâmetro de caule, número de folhas e área foliar por planta, peso fresco e seco por planta) e parâmetros de crescimento fisiológico (índice de área foliar e duração da área foliar, taxa de crescimento da cultura e taxa de assimilação líquida) com o rendimento de forragem do sorgo. Assim, a inclusão de leguminosas foi eficaz no aumento da fertilidade do solo, enquanto a inclusão de leguminosas a longo prazo por rotação de diferentes leguminosas é sugerida.
