Obesity is a major health problem in children & adults. Due to physiological changes during growing up in children and adolescents, it is difficult to develop one simple index for measurement of overweight & obesity. So, this study was carried out to identify simple methods like neck, waist, wrist, and mid upper arm circumference used as screening tools for overweight & obesity.: To correlate neck, waist, wrist & mid upper arm circumference with BMI for prediction of overweight. This was a cross-sectional study done on healthy urban school going children in the age group of 9 -17 years old. After measuring height and weight, BMI (body mass index) was calculated and nutritional status was classified. BMI was compared to neck, waist, wrist & mid upper arm circumferences to find out correlation. Cut off values of all four parameters to predict overweight & obesity were obtained by analysing the ROC (receiver operating characteristics) curve.: Total 907 students of age group 9 to 17 years old were screened. Correlation of Neck circumference (NC), Waist circumference (WC), Wrist Circumference (WrC) and Mid Upper Arm Circumference (MUAC) with BMI by Pearson’s correlation coefficient were correlated positively. The bland Altman plots showed higher concentration of points at the 95% limit of agreement (±1.96 SD) and that the mean difference in Z-score of two tests was equal or close to zero. AUROC for NC was 0.81, for WC 0.9, for WrC 0.811 and for MUAC 0.893.Neck circumference, Waist circumference, Wrist circumference and Mid upper arm circumference can be used as a screening test for predicting overweight or obesity in adolescents.

Ventilator Associated Pneumonia (VAP) is the second most common nosocomial infection in the United States, with high mortality and morbidity. Duration of hospital stay increased in average of 7 to 9 days with increase in treatment cost of $40,000 per patient. However, clinical evidence on the incidence of this infection is poor, especially from ICUs in India. : To study the incidence, risk factors and etiological agents in ICU patients developing VAP in a tertiary care hospital in India.In this study, patients who were kept on ventilator for more than 48 hours in ICU were enrolled. To clinically diagnose VAP, the modified clinical pulmonary infection score (CPIS) and clinical criteria were used as a screening tool. A full clinical history of the patients was documented, as well as the date of admission to the ICU, the date of initiation of mechanical ventilation, and the method of access to the patients' airway. A standard PROFORMA was used and the collected data was observed and analysed further. : In the present study out of 45 patients enrolled for the study, only 6 patients (13.3%) showed VAP. The presence of early VAP was observed in 3 patients whereas late VAP was also observed in 3 patients. The male and female patients exhibited similar incidences of VAP. The patients with an age group more than 70 years showed a maximum (37.5%) prevalence of VAP. Clinical features like fever and increased amount of secretions were found to be associated with the occurrence of VAP. Smoking and diseases like hypertension, kidney disease, malignancy and chronic lung disease were non-significantly associated with VAP. Whereas disease states like coma and enteral nutrition were found to be significantly associated with VAP. Acinetobacter and Klebsiella were the most common organisms isolated in our institution.: VAP remains a significant concern to patients admitted to an ICU for mechanical ventilation, highlighting the critical need for preventive measures.
To study the radiation induced oral mucositis in head and neck cancer - A prospective study
Authors: S Vijayakumar 
Published: April 2022

Patients suffering from Head and Neck Cancers (HNC), when treated with radiotherapy (RT), often experience Oral mucositis (OMS) side effects. OMS can complicate the treatment and worsen the management of HNC. The Radio-oncologist should find a way to minimize the incidence of OMS during the treatment of HNC. To study the Radiation-induced OMS in HNC patients and its associated factors. This prospective study was performed from October 2018 to September 2019. Total 80 patients of with HNC, who were treated with RT, were enrolled for the study with informed consent. In the study, 40 patients received RT and 40 received concurrent chemo-Radiotherapy (CCRT). Amongst 80 patients included in the study, 72.5% were found to be male. Poor oral hygiene was observed in 77.5% of patients in the study. The tongue cancer (35%) and Cancer of Stage IVa (47.5%) were more prevalent in the patients under study. OMS was observed maximum (60%) in 1 to 4 weeks of treatment. Inflammation response of epithelial mucosa to chemo- radiotherapy cytotoxic effects leads to mucositis, a painful side effect. This study gives proper understanding of Radiation-induced OMS and identifies the predisposing factors for OMS.

Etiology of cervical cancer consist of many factors like genetics, environmental factors etc. Fingertip patterns are formed under genetic control early in development but may be affected by environmental factors during first trimester of pregnancy. These patterns may represent the genetic makeup of a person and therefore his/her predisposition to certain diseases including carcinoma cervix. So this formed the basis of our study where we evaluated fingertip patterns as anatomical marker of carcinoma cervix. An analytical and comparative study done on 100 histo-pathologically confirmed cervical cancer patients and 100 age-matched normal healthy controls. Their fingerprints were analyzed to assess the association of cervical cancer with the fingertip patterns. Fingerprints were obtained by ‘Ink method’ as it was mentioned by Cummins and Midlo. Data on differences in patterns of cases and controls were tested for it’s statistical significance. Statistically significant lower number of arch patterns was observed in the fingerprints of both hands combinedly of the cancer patients as compared to controls. It was also seen that the percentage frequency of arch pattern when compared separately for right and left hands of cancer patients and controls, the frequency of arch pattern was statistically significantly lower in left hands of cases than controls. So it can be concluded that there are significant difference in fingertip patterns of cervical cancer patients from healthy people and Dermatoglyphics i.e., the study of ridge pattern on the finger, palm and soles may be utilized to identify the people at risk of carcinoma cervix.

Published: April 2022

Background: Proton Pump Inhibitors (PPIs) are the most common medicine for the treatment and prophylaxis of acid peptic conditions. The inappropriate use of the PPIs, mainly the intravenous form of pantoprazole may lead to excessive cost and unexpected adverse effects.
Objectives: The present study aimed to evaluate the use of intravenous pantoprazole in the International Heart Center in the north of Iran.
Methods: The current retrospective study was performed on 215 patients hospitalized in Fatemeh Zahra Hospital in Sari City, Iran. Patients’ demographics, the type and doses of pantoprazole, and other relevant clinical data were recorded from their documentation. The appropriate use of pantoprazole was evaluated according to recommendations provided by Medscape 2020, and UpToDate 2020.
Results: Prescribing PPI was appropriate for 53.5% of the examined patients; however, the majority of intravenous prescription cases were inappropriate (76.7%). Oral PPIs could have been used in 93.5% of the cases; however, they received the parenteral form of pantoprazole. The main cause of pantoprazole prescription in the explored hospital was stress ulcer prophylaxis, with the median 4/18 days used, which internal specialists in most of the cases (45.6%) prescribed.
Conclusion: In the current study, administrating intravenous pantoprazole was inappropriate in most of the cases. As a result of this improper administration, the extensive cost is exposed to the healthcare system, i.e., likely to be unsafe for patients. Accordingly, risk and indication evaluation for the prescription of pantoprazole should be a priority in each patient. Finally, it seems necessary to determine a protocol for PPI prescription per hospital for the rational use of drugs.

La alternancia ser/estar ha inspirado numerosos estudios y, consecuentemente, una significativa variedad de conceptos técnicos. Ante este panorama, proponemos avanzar hacia un refinamiento de los parámetros aspectuales empleados, con énfasis en los niveles lingüísticos en los que se originan y en la diferenciación entre semántica léxica/construccional. A partir de diagnósticos específicos, proponemos: primero, que ser y estar se alejan de la noción estándar de cópula y verbo estativo y son cuanto menos ambiguas respecto al tipo eventivo de las construcciones que articulan; segundo, que propiedades asignadas en la literatura no responden a lacópula, sino a la construcción; tercero, que la delimitación [boundedness] capta más eficientemente las situación de ser/estar, como propiedad semántica diferente y lógicamente distinguible de la perfectividad y telicidad.

Authors: Lawrence Lucy Ongaya , Muathe Stephen Makau 
Published: April 2022

This study aims to examine the effect of customer loyalty programs on customer buying behavior in supermarkets in Nairobi City County, Kenya. Specifically, the study sought to establish the effect of reward programs, point accumulation programs, and reward frequency programs on customer buying behavior. A descriptive research design was employed, and questionnaires and interview guides were used to collect data. A sample of 384 respondents was selected from a target population of 985,016 using the non-probabilistic purposive sampling method. Findings indicate that consumers’ level of preference for the particular supermarket loyalty programs was high in specific supermarkets. It was also found that points’ redemption rates differed among the supermarkets. The majority of the supermarkets allowed customers to redeem their points at any time and customers preferred benefits connected to frequent visits and fast points reimbursement based on the reward method used. The study concluded that point cumulative program and reward method program positively and significantly affects consumer buying behavior but reward frequency negatively and significantly affected customer buying behavior. The study recommended that the point accumulation program should be made easier for customers by the marketing departments in the supermarkets.
WPD-logy as a tool of the improvement of education in the 21st century
Authors: Donskikh O. A. , Razumov V. I. 
Published: May 2022

The introduction to the article describes the situation that has developed in the system of higher education in Russia after Perestroika and has led to an unambiguous predominance of administration over professionally significant employees.The objective of the article is to arrange a detailed analysis of the reasons for the inversely proportional relationship between the level of creativity and the level of bureaucratization that is emerging in modern conditions. As an example, such an aspect of bureaucratic activity as the development and implementation of standards, represented, in particular, by the work programs of disciplines (WPD) and work programs of practices (WPP), is taken.The main research methodology is a comparative and comparative historical analysis, which allows to identify the features of the activities for the creation of WPD and WPP, which is considered necessary to improve the level of methodological work and the corresponding improvement in the quality of teaching.The result of the study allows us to show that the organization of methodological work is built hierarchically, with methodologists at the upper levels, and all teachers, including professors, at the lower levels. The work of the making of educational programs has turned, on the one hand, into a separate discipline, and, on the other hand, into a process, completely autonomous from educational and scientific activities. It is necessary not for educational activities, but exclusively for passing confirmations from authorities (attestations). In addition, rigid and constantly changing requirements for standards (including changes of the standards themselves) are reinforced by additional requirements for the quality of teaching staff, which are growing according to the awareness of the ineffectiveness of previous measures. This practice is considered in the context of the global trend of transformation of universities from “universities of culture” to the “universities of excellence” (in Bill Readings’ terminology).The authors of the article come to conclusion that as a result of the ongoing educational policy, a situation arises not just of imitation of education, but of imitation of imitation. The heyday of the WPD-logy is an important modern indicator that the real trajectory of development of most universities in modern Russia actually demonstrates a sign ificant decline of the level teaching.

Abstract
The sediment bedding direction and loading-unloading have significant effect on permeability of coal sample. The coal samples taken from Zhangcun Coal Mine in Shanxi were used to measure coal permeability with different sediment beddings under the effect of loading and unloading by the triaxial coal-rock seepage experimental apparatus. The influence of gas pressure, loading-unloading, and sediment bedding direction on the permeability of coal samples was analyzed, and the functional relationship among these parameters was recovered by fitting. The results show that the permeability of all vertical, dip, and horizontal bedding coal samples decreases exponentially with the increase of effective stress during stress loading, while the permeability of three kinds of bedding coal samples increases exponentially with the decrease of effective stress during stress unloading. Under the same gas pressure, the fracture space of coal samples with vertical and dip bedding is more likely to be compressed and closed at the initial stage of loading, resulting in great decrease of the permeability. In the initial stage of unloading, the microcracks and natural beddings in coals gradually expand and connect. Due to the well development of fractures, the permeability of vertical bedding coal samples increases greatly, while the permeability of dip and horizontal bedding coal samples increases slightly. In the loading process, the permeability of coal sample is vertical bedding &gt; dip bedding &gt; horizontal bedding in order. For the tested samples, the permeability of vertical bedding coal samples is 1.3 to 2.8 times that of dip or horizontal bedding coal samples. In the unloading process, the permeability of the vertical bedding coal samples was 2.8 to 3.3 times that of the dip or horizontal bedding coal samples.

Abstract
In recent years, plant-based nanoparticle synthesis and research attained significant attraction due to its potential biological application. Presently studies in bio-nanotechnology have attained fascinating attention due to the use of nanoparticles in various fields of life. We used aqueous leaf extract of Alpinia calcarata to synthesize silver nanoparticles (AgNPs) and characterized them using UV-vis spectra, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and other techniques. These AgNPs' antibacterial and anticancer properties were also investigated. SEM analysis depicted the uniformly distributed spherical nanoparticles with 20 to 22 nm size. EDX analysis revealed the presence of silver ions with a strong signal. Gram-positive and negative human pathogenic bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumoniae), and Pseudomonas aeruginosa were inhibited by the synthesized AgNPs. Antibacterial activities of the AgNPs were directly proportional to the concentration. The diameter of the zone of inhibition of AgNPs on bacteria varies from species to species. AgNPs were also found to have anticancer action against the MFC7 human breast cancer cell line. The anticancer activity of synthesized AgNPs was directly proportional to the concentration. The IC50 of this AgNP on the MCF7 cell line was determined using a linear regression equation and found to be 219.64 µg/ml. Thus, A. calcarata aqueous leaf extract can be used to synthesize AgNPs in an eco-friendly manner, and these AgNPs can be used in anticancer and antibacterial medicines, food, and cosmetic industries after clinical studies.

Abstract

In the post-COVID-19 era, port congestion has become the norm, and the digitalization of shipping has accelerated due to the sporadic occurrence of global outbreaks. How to promote blockchain technology to improve the efficiency of port customs clearance and logistics transparency has become a hot research question. In this paper, we investigate the value of blockchain-based vertical cooperation led by a port or a shipping company in a one-to-two shipping service competition model. Meanwhile, we discuss consumer surplus and social welfare under different cooperation frameworks. We find that i) investment in blockchain technology can significantly increase the profits of port and shipping supply chain participants. ii) From the point of view of profit, when the investment efficiency of ports and shipping companies satisfies a certain relationship, there is a balanced strategy for both parties to invest in blockchain technology. iii) The more intense the competition for the services of shipping companies on the blockchain nodes, the lower the level of blockchain technology to improve the logistics capabilities of the port and shipping supply chain node companies. iv) From the perspective of maximizing consumer surplus and social welfare, the port’s investment in blockchain technology brings more consumer surplus and social welfare. The abovementioned findings can provide a reference for the daily operations of ports and shipping companies and present decision support for the government to formulate blockchain technology promotion policies.

Abstract
In the present study, a new hybridization strategy for predicting the groundwater table (GWT) and drought analysis is presented. Therefore, a hybrid of the bi-directional long short-term model (BLSTM) and the Harris hawk optimization (HHO) algorithm, namely the BLSTM–HHO algorithm, is applied. In this algorithm, the lagged data of the GWT are used as the input, whereas the current GWT data are used as the output. Additionally, the standalone BLSTM, the long short-term model (LSTM), artificial neural networks (ANN), Seasonal Autoregressive Integrated Moving Average (SARIMA), and the Autoregressive Integrated Moving Average (ARIMA) are employed as benchmark simulating algorithms. The results show that the BLSTM–HHO algorithm has more accuracy than the other investigated simulating algorithms based on the different evaluation criteria such as relative root mean squared error (RRMSE), Nash–Sutcliffe coefficient (NSE), and refined Willmott index (dr). The prediction results (from 2018 to 2022) in all three investigated aquifers show the decline of the GWT (−5.40 m for Brojen aquifer, −7.23 m for Javanmardi aquifer, and −5.81 m for Shahrekord aquifer). Accordingly, the drought analysis by the ground resource index (GRI) in the investigated areas shows that drought is expected to be continued for the next 5 years with an increasing magnitude of severity.
