OBJECTIVE

The objective of this study was to establish the effect of endoscopic endonasal surgery on longitudinal quality of life (QOL) in patients with anterior skull base meningioma.

METHODS

A prospectively collected cohort of consecutively operated anterior skull base meningiomas was analyzed. All cases were performed using the endoscopic endonasal approach (EEA). Sinonasal-specific and overall QOL were measured using the 22-Item Sinonasal Outcome Test and the Anterior Skull Base Questionnaire longitudinally (at 3 weeks, 6 weeks, and 3, 6, and 12 months) across the first postoperative year. The relationship between surgical and QOL outcomes to clinical and radiological characteristics was analyzed using multivariate regression.

RESULTS

Fifty cases were available, with a mean age of 61.5 years and female predominance (74.0%). Visual dysfunction and headache were the most common presenting symptoms, and tumors commonly took origin from the planum (46.0%), tuberculum (44.0%), and olfactory groove (24.0%). Median tumor volume was 4.6 cm3. Visual improvement was noted in 73.1% of cases with preoperative field deficits, while nonimprovement was associated with greater tumor height (p = 0.04). Gross-total resection was not possible in patients with 360° vessel encasement and high-grade cavernous sinus extension with ophthalmoplegia. Postoperative diabetes insipidus was observed only in cases with suprasellar extension. Sinonasal-specific QOL worsened transiently after surgery but returned to baseline levels after 3 weeks. Olfaction and taste scores returned to preoperative baseline scores within the year. Overall QOL at presentation was worse in those with larger tumors (p = 0.04) and visual failure (p = 0.04) and better in those presenting with headache (p = 0.04). Transient worsening of QOL was seen in the first 3 weeks, which returned to baseline by 6 weeks, and then improved to above preoperative levels at 6 months and beyond. Worse QOL at baseline (p = 0.01) and visual improvement (p = 0.01) predicted QOL improvement after surgery.

CONCLUSIONS

Longitudinal QOL in anterior skull base meningioma has been examined for the first time. Endoscopic endonasal surgery improves overall QOL after a transient 3-week worsening due to the sinonasal morbidity of the approach. Visual function is intimately tied to QOL, with worse vision associated with worse preoperative QOL, and QOL improving in parallel with visual restoration after surgery. The EEA is associated with better visual outcomes and should be the preferred approach in accessible tumors.

The COVID-19 outbreak has had a serious impact on investment activities in Indonesia. One of the aspects of concern in the midst of the coronavirus outbreak is the decrease in investor interest in capital market activities in Indonesia. Therefore, it can be predicted that there is a potential decrease in the level of profit (return) that will be received by shareholders. The purpose of this study is to investigate the influence of liquidity and systematic risks on returns. The analysis tool used to test the influence between panel variables is the analysis of panel data regression. The findings of this study are that liquidation has no significant effect on the return of company shares. In addition, the second finding proves that systematic risk has a positive and significant effect on the return of the company's shares. Our findings are reinforced by the results of robustness test statistically, which confirms that companies that have a high beta value, then the return of the company's shares will tend to be high.

The present study aims to identify the promotion of family and community participation in basic education schools and their involvement in various aspects, to this end, a review of the available state of the art was carried out, based on key terminologies and the grouping by categories of this fact, which is evident in other states of the region and the world. It also aims to publicize the results of the analysis carried out. We found that educational policies lack solid guidelines or few efforts are made to promote participation. Likewise, that educational management only encourages basic levels of participation: informative and collaborative. In addition, there is no pedagogical management in place that allows for this involvement in a positive way, despite the recognition of its importance in improving student learning.

El presente proyecto se lo ha realizado en la Unidad Educativa Benemérita Sociedad Filantrópica en el séptimo grado de educación básica, periodo lectivo 2015 – 2016. El objetivo de la investigación fue examinar la influencia de la lectura crítica en la calidad del aprendizaje significativo mediante un estudio bibliográfico y análisis estadístico de campo. En la investigación se emplearon encuestas que se aplicaron a docentes, directivos y estudiantes del plantel, el análisis de los datos detalló la falta de interés que presentan los estudiantes hacia la lectura, tornando compleja la comprensión de la misma. Desde la perspectiva de los estudiantes, las lecturas realizadas en clase se tornan teóricas y tediosas, lo cual los direcciona a distraerse con facilidad dentro del proceso de enseñanza-aprendizaje. Esto ha creado barreras al momento de fomentar la interacción activa entre los miembros de la clase. Por otra parte, se constató que algunos docentes no aplicaban actividades dinámicas que relacionen los contenidos educativos con diversas experiencias vividas minimizando el desarrollo de aprendizajes significativos en los estudiantes. Esta serie de aspectos fundamentaron la elaboración de una propuesta que permita al docente aplicar actividades innovadoras que puedan adaptarse a los diferentes contenidos educativos presentes en el área de Lengua y Literatura.

Published: January 2022

The effect of utilising energy derived from fossil sources on the environment has aroused research interest in alternative and sustainable energy sources. Synthesis gas, a mixture of carbon monoxide (CO) and hydrogen can be used as starting materials in hydrogenation reactions to produce chemical intermediates that can be used in various processes. This study investigates the robustness of applying a fine Gaussian support vector machine algorithm for predicting light olefins from catalytic CO hydrogenation using magnesia nanoparticles-based catalysts. The datasets obtained from the CO hydrogenation reaction consist of input parameters such as magnesia nanoparticles contents, reaction temperature, and reactor pressure, and the output parameters which include CO conversions and the selectivity of light olefins (CH4, C2H6, C2H4 C3H8, C4H8, and C3H6). The dataset was trained and employed for the prediction of the light olefins using a support vector machine with an inbuilt Fine Gaussian Kernel function. The performance of the support vector machine was evaluated using the coefficient of determination (R2), root mean squared error (RMSE), mean square error (MSE), and the mean absolute error (MAE). The support vector machine showed significant potential in the prediction of CO conversion, CH4 selectivity, C2H6 selectivity, and C2H4 selectivity as indicated by R2 of 0.770, 0.800, 0.730, and 0.930, respectively. While less predictive performance was obtained for the prediction of C3H8 selectivity, C4H8 selectivity and C3H6 selectivity as indicated by R2 of 0.630, 0.610, and 0.320, respectively.

Background: Retinal neurodegeneration is evident in early diabetic retinopathy (DR) which may be associated with other neurodegenerative diseases like Alzheimer's disease (AD). Objective: To investigate diabetes and DR as a risk marker of present and incident AD. Methods: A register-based cohort study was performed. We included 134,327 persons with diabetes above 60 years of age, who had attended DR screening, and 651,936 age- and gender-matched persons without diabetes. Results: At baseline, the prevalence of AD was 0.7% and 1.3% among patients with and without diabetes, respectively. In a multivariable regression model, patients with diabetes were less likely to have AD at baseline (adjusted OR 0.63, 95% CI 0.59–0.68). During follow-up, incident AD was registered for 1473 (0.35%) and 6,899 (0.34%) persons with and without diabetes, respectively. Compared to persons without diabetes, persons with diabetes and no DR had a lower risk to develop AD (adjusted HR 0.87, 95% CI 0.81–0.93), while persons with diabetes and DR had higher risk of AD (adjusted HR 1.24, 95% CI 1.08–1.43). When persons with diabetes and no DR were used as references, a higher risk of incident AD was observed in persons with DR (adjusted HR 1.34, 95% CI 1.18–1.53). Conclusion: Individuals with diabetes without DR were less likely to develop AD compared to persons without diabetes. However, individuals with DR had a 34% higher risk of incident AD, which raise the question whether screening for cognitive impairment should be done among individuals with DR.
A numerical method for approximating the solution of fuzzy fractional optimal control problems in caputo sense using legendre functions
Authors: Mirvakili M. , Allahviranloo T. , Soltanian F.
Published: January 2022

Fractional order differential equations accurately model dynamic systems and processes. In some of the fractional optimal control problems (FOCPs), due to the ambiguity in the initial conditions and the transfer of ambiguity to the solution, it is necessary to use fuzzy mathematics. In this paper, a numerical method is presented to approximate the solution for a class of Fuzzy Fractional Optimal Control Problems (FFOCPs) using the Legendre basis functions. The fuzzy fractional derivative is described in the Caputo sense. The performance index of an FFOCP is considered as a function of both the state and the control variables, and the dynamic constraints are expressed by a set of Fuzzy Fractional Differential Equations (FFDEs). After obtaining Euler–Lagrange equations for FFOCPs and the necessary and sufficient conditions for the existence of solutions, using the definition of generalized Hukuhara differentiability (types I, II), the problem is considered in two cases. Then the distance function and an approach similar to the variational type along with the Lagrange multiplier method are used to formulate and solve the equations in a system. Time-invariant and time-varying examples are provided to assess the presented method. Numerical results show a similar trend for the state and control variables for various numbers of Legendre polynomials. Also, the convergence of state and control variables for the time-invariant system can be seen, and the same is true for control variables for the time-varying system.
Model for evaluating the security of wireless sensor network with fuzzy number intuitionistic fuzzy information
Authors: Li Feng
Published: January 2022

Many experts and scholars focus on the Maclaurin symmetric mean (MSM) equation, which can reflect the interrelationship among the multi-input arguments. It has been generalized to different fuzzy environments and put into use in various actual decision problems. The fuzzy data intuitionistic fuzzy numbers (FNIFNs) could well depict the uncertainties and fuzziness during the security evaluation of Wireless Sensor Network (WSN). And the WSN security evaluation is frequently viewed as the multiple attribute decision-making (MADM) issue. In this paper, we expand the generalized Maclaurin symmetric mean (GMSM) equation with FNIFNs to propose the fuzzy number intuitionistic fuzzy generalized MSM (FNIFGMSM) equation and fuzzy number intuitionistic fuzzy weighted generalized MSM (FNIFWGMSM) equation in this study. A few MADM tools are developed with FNIFWGMSM equation. Finally, taking WSN security evaluation as an example, this paper illustrates effectiveness of the depicted approach. Moreover, by comparing and analyzing the existing methods, the effectiveness and superiority of the FNIFWGMSM method are further certified.
A new three-way group decision-making model based on geometric heronian mean operators with q-rung orthopair uncertain linguistic information
Authors: Wang Huidong , Zhang Yao , Bai Chuanzheng
Published: January 2022

As an effective tool for three-way decisions (3WD) problems, decision-theoretic rough sets (DTRSs) have raised increasing attention recently. In view of the advantages of q-rung orthopair uncertain linguistic variables (q-ROULVs) in depicting uncertain information, a new DTRSs model based on q-ROULVs is proposed to solve three-way group decision-making (3WGDM) problems. Firstly, the loss function of DTRSs is depicted by q-ROULVs and a q-rung orthopair uncertain linguistic DTRSs model is constructed subsequently. Secondly, to aggregate different experts’ evaluation results on loss function in group decision-making (GDM) scenario, the q-rung orthopair uncertain linguistic geometric Heronian mean (q-ROULGHM) operator and the q-rung orthopair uncertain linguistic weighted geometric Heronian mean (q-ROULWGHM) operator are presented. Related properties of the proposed operators are investigated. Thirdly, to compare the expected loss of each alternative, a new score function of q-ROULVs is defined and the corresponding decision rules for 3WGDM are deduced. Finally, an illustrative example of venture capital in high-tech projects is provided to verify the rationality and effectiveness of our method. The influence of different conditional probabilities and parameter values on decision results is comprehensively discussed.
Detection of insecticide detoxification enzymes activities in Aedes aegypti mosquito, the vector of dengue fever in Saudi Arabia
Authors: Algamdi Abdullah G. , Mahyoub Jazem A.
Published: January 2022

In this study, the sensitivity of Aedes aegypti mosquitoe larvae to four types of pesticides two phosphorous-based and two pyrethroid insecticides was investigated. The larvae revealed approximately 1.126-fold more susceptibility to Safrotin (LC50 = 0.127 ppm) than Fendure (LC50 = 0.143) in the case of phosphorous-based pesticides and approximately 1.265-fold more susceptibility to AlphaQuest (LC50 = 0.0347 ppm) than Klash (LC50 = 0.0439) in the case of pyrothroid insecticides. Comparison between groups revealed that AlphaQuest was more effective than Klash, Safrotin and Fendure by approximately 1.3, 3.6 and 4.1-fold, respectively. The presence of enzyme activities relevant to insecticide resistance was often evaluated using enzyme assays to detect the underlying resistance mechanisms that may not be detected using bioassays. In this study, the results revealed significant decrease in the activity of esterase, glutathione- S- transferase and acetylcholine esterase enzymes to varying degrees. There were significant increases in catalase and total glutathione activity in all treatments compared to the control. The study concluded that this variation in enzyme activities is due to the type and purity of the additive compound and the source and purity of the active ingredient. The study recommends using the catalase enzyme and total glutathione as a biomarker indication for pesticide synergistic intoxication in aquatic animals.

Authors: Kotowski Susan E. , Davis Kermit G. , Barratt Clare L.
Published: January 2022

BACKGROUND: Teachers have had to deal with many of the negative aspects of COVID-19 over the past year. The demands associated with the sudden requirement to teach remotely, and later having to manage hybrid (both in person and online) learning may be having adverse effects on the mental and physical health of teachers. OBJECTIVE: To determine whether COVID-19 continued to impact teacher stress, burnout, and well-being a year into the pandemic. METHODS: An online survey was sent out to 5300 teachers in public and private schools, and 703 completed the survey. RESULTS: Stress and burnout continue to be high for teachers, with 72% of teachers feeling very or extremely stressed, and 57% feel very or extremely burned out. Many teachers struggled to have a satisfactory work-family balance (37% never or almost never; 20% only has sometimes). CONCLUSION: School systems must start to deal with the mental and physical health of teachers before a large number of them leave the profession.
Strengths and Weaknesses of the Russian Concept for the Development of Production and Use of Electric Vehicles Until 2030
Authors: Iosifov Valeriy I. , Ratner Pavel D.
Published: January 2022

Russia has not yet paid due attention to the issues of the transition to electric transport. Only in August 2021, the Russian Government approved a Concept for the development of production and use of electric road transport in the Russian Federation for the period up to 2030. The aim of this study is analysis the Concept from the point of view of world experience in stimulating the development of the electric vehicle market.  The study showed that the most elaborated directions of the Concept for the development of production and use of electric road transport in the Russian Federation for the period up to 2030 are the direction of creating a national production of batteries and hydrogen fuel cells, as well as the direction of creating national production facilities and localizing foreign production of electric vehicles, including cars with hydrogen fuel cells. The least developed direction of the Concept is the direction of creating a national base for certification and testing of electric vehicles, which indicates the problem of a lack of competencies in the scientific and technical sphere.
Energy Mix Optimization from Energy Security Perspective Based on Stochastic Models
Authors: Maman Yaser Kanani , Maleki Abbas
Published: January 2022

As a problem, generally, energy security components do not interfere with the calculation of the optimal energy supply situation. Energy security indices so-called 'passive indices' cannot illustrate comprehensive optimal situation. In this paper, we are looking to find a solution to make a framework of the impact of energy security on energy supply in order to obtain comprehensive analysis of the economic optimal point. Method is based on the competition of energy costs to meet demand during the study period. Threats that have been addressed in the energy security are seen as risky and stochastic parameters in the model. The nature of these parameters is of uncertainty type, therefore, based on the probable scenarios of the stochastic model, the perspective of the energy supply system is drawn up based optimizing the supply of different carrier energy. We apply this method on Iran's import of gasoline as a national threat of energy supply.  According to the results, in the period when there are threats of energy imports, energy storage is a low-cost and safe way to compensate for the damage caused by threats. Assuming an annual growth of 5%, capacity can be increased to 8 million barrels during the threat period. The optimal index varies in this period between 0.04 and 0.06.
Nurse care for diabetic foot patient
Authors: Cunha Amanda Priscilla da
Published: January 2022

Introduction: The diabetic foot also called by a multifaceted pathophysiological state is characterized by lesions that arise from the feet of the person with diabetes without adequate treatment and specific care. It is estimated that the incidence of diabetic foot ulcer reaches 6.3% of diabetic patients and its prevalence approaches 10%, and people with low socioeconomic status are the greatest victims. In view of this evidence, the work is based on the following problem: What care do nurses develop in patients with diabetic feet? General objective: To evidence the care of diabetic foot related to the practice of nurses. Methodology: An integrative review was conducted in the Specialized Bibliographic Database in nursing (BDENF), latin american and caribbean literature in health sciences (LILACS) and the Scientific Electronic Library Online (SCIELO) and which resulted in seven articles. Results: The studies showed how the care of nurses with diabetic foot health education, continuing and permanent education, evaluation techniques to diabetic foot that involve physical examinations and self-care of patients with diabetic feet. It is reinforced that this care should be performed as a priority by nurses, since nurses have specific and qualified care to the patient in their main attributions. Conclusion: It is concluded, therefore, that the study identified several forms of care provided by nurses and that all these forms are important for the continuity of treatment and the prevention of complications, however, it is up to the nurse to be a professional who values the quality of their care based on theoretical concepts that lead to frequent training.
Effects of Electromagnetic Treatment on Growth and Photosynthesis of Three Common Freshwater Phytoplankton Species
Authors: Levieva Jennifer Bello
Published: January 2022

A study was done using three common freshwater phytoplankton species of Chlorella vulgaris, Microcystis aeruginosa, and Cyclotella pseudostelligera, where the effects of two low power electromagnetic fields (EMF) on phytoplankton growth and photosynthesis were assessed. Growth was quantified by direct cell count and photosynthetic rates were measured as oxygen production with an oxygen probe. Results showed that maximum densities of C. vulgaris and M. aeruginosa were increased by application of an EMF, as was the growth rate of M. aeruginosa, and there were also differences in respiration rates. C. pseudostelligera, in contrast, had lower growth rates and maximum cell densities when exposed to EMF. These results may be attributed to differences in cell structures, particularly differences in the composition of cell membranes, and charge environments. Future studies should focus on mixed cultures as well as examining how specific cellular responses such as nutrient uptake may differ in response to EMF.

Published: January 2022

The aim of this paper is to describe daily patterns and changes in time use of people dealing with elderly informal care in Poland. Based on Time Use Survey 2004 and 2013 we show that with increasing population of adults requiring care the profile of average caregiver also changes. We observe more caregivers. More often they are women and more often are retired. In consequence average time spent on caregiving also increases. We conclude that this trend will continue and therefore both market and state suppy of the caregiving services is required.

Bu çalışmada, yapay zekâ temelli tahmin yöntemlerinden Yapay Sinir Ağları (YSA) ve bir üstel düzeltim yöntemi olan Holt Winters’ ile Türkiye’de sıfır otomobil satış adetlerinin tahminlemesi gerçekleştirilmiştir. Çalışmada, bağımlı değişken “otomobil satış adetleri” iken; bağımsız değişkenler “döviz kuru, tüketici güven endeksi, gayrisafi yurt içi hasıla (GSYHİ) ve reel kesim güven endeksi” olarak seçilmiştir. Türkiye İstatistik Kurumu (TÜİK), Türkiye Cumhuriyeti Merkez Bankası ve Otomobil Distribütörleri Derneği’nden alınan 2015 – 2020 yılları arasındaki aylık veriler üzerinde çeşitli normalizasyon yöntemleri denenmiş, çoklu regresyon analizi yapılmış ve değişkenlik katsayısı hesaplanmıştır. Minimum hata performansı gösteren istatiksel normalizasyon yöntemi (Z-Skor) seçilerek geçmiş verilerden hareketle ağ mimarisi ve çeşitli parametreler belirlenmiş ve YSA’nın ileri beslemeli geri yayılım algoritması kullanılarak 2019 ve 2020 yıllarında gerçekleşen sıfır otomobil satış adetleri tahmin edilmiştir. Ardından, YSA’nın performansı çeşitli performans göstergelerine göre Holt Winters’ yöntemi ile karşılaştırılarak yorumlanmıştır. YSA’nın Holt Winters’ yöntemine kıyasla daha iyi sonuç verdiği tespit edilmiş ve tahminlerdeki sapmaların sebepleri yorumlanmıştır.
Extremely Rare Transitional Cell Carcinoma of The Round Uterine Ligament - Histopathogenesis, Immunohistochemical Analysis, Prognosis and Optimal Complex Treatment
Authors: Marinova Lena , Evgeniev Nikolay , Solakova Guler
Published: January 2022

For the first time in the English medical literature is presented an extremely rare transitional cell carcinoma of the round uterine ligament. Transitional cell carcinoma (TCC) of the ovary was first defined by Austin and Norris in 1987. Malignant primary tumors arising in the uterine broad ligament are extremely rare. To date, its pathogenesis is unclear. In the discussion we focus on the pathomorphological and immunohistochemical analysis of transitional cell carcinomas in the genital tract and their differential diagnosis from transitional cell carcinomas of the urinary tract / ureter and bladder. Due to the high malignant potential, the prognosis is unfavorable and requires optimal complex treatment, including radical surgery followed by systemic chemotherapy.
Effect of Treatment with Dextroamphetamine Sulfate on Weight Loss Up To 5 Years in Women Unable to Lose Weight by Dieting and Its Efficacy on Some Other Unusual Manifestations of The Increased Cellular Permeability Syndrome
Authors: Check Jerome H , Check Diane , liss Joanne R
Published: January 2022

Purpose: To evaluate the efficacy of treatment with dextroamphetamine sulfate of refractory weight loss by dieting related to fluid retention secondary to the increased cellular permeability syndrome over a 5-year period. Methods: Women were excluded for pathological causes of fluid retention, e.g., hypothyroidism, Cushing’s syndrome, heart failure, or renal or hepatic disease. Dextroamphetamine sulfate was initiated at 15mg extended-release capsules with the option of increasing the dosage as necessary up to a maximum of 60mg a day. Results: Forty-four percent of the women lost at least 10% of their initial body weight in 6 months and 42% still lost at least 10% by 5 years. For the first 4 years there were about 15% who lost about 15% of their initial body weight. At 5 years only 7% failed to have any weight reduction compared to their initial weight. Conclusion: The amphetamines seemed to cause weight reduction by diminishing fluid retention rather than causing caloric reduction.
The Portryal of Christianity in Achebe’s Arrow of God: A Postcolonial Perspective
Authors: Tatang Iskarna
Published: January 2022

AbstractThe emergence of postcolonial criticism makes the voice of Africans’ colonial experience heard and seriously considered. In some ways, this voice is a little bit different from what the European poets or novelists have expressed in their literary texts. For most Europeans, colonialism is perceived as a civilizing force that benefits and progresses to the colonized African societies, primarily through one of its arms: Christianity. Although this religion, as most missionaries propose, has nothing to do with the worldly affair, such as a lust for natural resources and colony, it becomes an important cultural element to help the Europeans conquer the colonized African natives. During the era of colonialism, Christianity in Western discourse is perceived as a means of setting the African natives free from the barbaric traditional belief and savage way of life. Through Christianity, the colonized African natives are educated and taught to live a more modern and civilized life. However, some African writers at times give a different perspective on Christianity. This article explores how Christianity is portrayed through the characters and conflicts in Arrow of God (1964), a novel written by a Nigerian named Chinua Achebe. This portrayal can lead to a postcolonial discourse the novel intends to propose.

Keywords: Christianity, colonialism, postcolonial criticism, postcolonial discourse

Abstrak

Munculnya kritik sastra poskolonial menjadikan suara yang mengekspresikan pengalaman kolonialisme dapat didengar dan sungguh-sungguh dapat diberi perhatian. Suara ini dalam beberapa hal agak eberbeda dengan apa yang disampaikan oleh novelis dan penyair Eropa dalam karya-karya mereka. Bagi kebanyakan orang Eropa, kolonialisme dipandang sebagai kekuatan pemberadaban yang dapat memberikan keuntungan dan kemajuan bagi masyarakat Afrika yang terjajah, terutama melalui salah satu tangan kanannya, yaitu agama Kristen. Meskipun agama ini tidak terkait dengan urusan nafsu dunia, seperti keinginan untuk menguasai sumber daya alam maupun tanah koloni seperti yang sering dikatakan oleh para misionaris, agama ini menjadi elemen penting untuk membantu kaum kolonial Eropa manaklukkan orang-orang pribumi Afrika. Selama masa kolonial, agama Kristen dalam wacana Barat dipandang sebagai media untuk membebaskan orangorang Afria dari kepercayaan tradisional yang barbar dan cara hidup yang tidak beradab. Melalui agama ini, orang-orang pribumi Afrika dididik dan diajar untuk menghidupi kehidupan yang lebih modern dan beradab. Namun demikian, beberapa sastrawan Afrika memberikan perspektif yang berbeda terhadap agama Kristen. Artikel ini akan mengeksplorasi bagaimana agama Kristen digambarkan melalui tokoh dan konflik dalam novel Arrow of God (1964) karya sastrawan Nigeria, Chinua Achebe. Gambaran ini akan menuntun pembaca pada wacana poskolonial yang dibangun oleh novel ini.

Cotton production trends in Pakistan: An integrative review
Authors: Mehmood Ch Khalid , Ashraf Saleem , Ashraf Ijaz
Published: January 2022

Cotton is regarded as a cash crop in Pakistan and the country is ranked 5th in terms of production and 3rd importer in the world as well. Cotton production in Pakistan is under huge pressure and it's continuously declining over the period. This review aimed at exploring the different reasons for the cotton production decline. This review comprises two major sections. In the first section, percentage change in area, production and yield of cotton in Punjab, Sindh and Pakistan is calculated from 1990-2020. This analysis indicated a drastic decline in area, production and the average yield of cotton in the country. In the second section, previously published literature is consolidated to explore the different constraints causing change in the area, production and average yield of cotton. The major constraints causing the sweeping decline included environmental constraints, climate change, water-related constraints, agronomic constraints and socio-economic related constraints. This study concludes that cotton crop decline is not in favor of cotton associated industry, farming groups and national economy and it is much needed to bring reforms for the revival of cotton crop. This study urges further research on exploring the reasons that are compelling farmers to reduce the cotton area, quitting cotton cultivation or switching to other crops.
