Statement of the Problem:
Healthcare workers (HCW) are the most vulnerable group for contracting SARS-CoV-2. Assessment of seroprevalence of SARS-CoV-2 antibodies among HCW, thus can provide important data on pathogen exposure, infectivity, and adherence to personal protective equipment (PPE). The present study aimed at assessing SARS-CoV-2 seroprevalence among HCW and exploring associations with demographics, category of exposure to COVID-19 patients, preventive measures taken and relation with COVID-19 symptoms.

Method of Study:
HCWs with a minimum gap 2 weeks from last duty were eligible to participate in the study. The enrolled HCW were categorized into high-risk and low-risk category based on work in COVID-19 areas. HCWs SARS-CoV-2 specific IgG and IgM antibodies were detected using rapid immunochromatography test.

Results:
Out of 821 randomly selected HCWs, either IgM or IgG antibody was detected in 32 HCWs (32/821, 3.9%). Only IgM antibodies were detected in 14 (1.7%), only IgG was detected in 9 (1.0%), and both IgM and IgG antibodies were present in 9 HCWs. Seropositivity was significantly higher in high-risk category (5.7% vs. 2.2.%), HCWs who ever had COVID-19 related symptoms in last 3 months (5.6% vs. 2.8%), and those who had earlier tested positive for SARS-CoV-2 with real-time reverse transcriptase PCR (36.6% vs. 3.5%). Seroprevalence was highest (6.9%) among housekeeping and sanitation staff.

Conclusions:
Overall, low seroprevalence of SARS-CoV-2 antibodies in our HCWs is an indicator of effective infection control practice. HCW posted in dedicated COVID ward need more stringent implementation of infection prevention measures.

Published: August 2021

Background:
Currently, there is no data on the impact of COVID-19 on patients' income and work in India.

Methods:
We conducted a cross-sectional study at a tertiary hospital in New Delhi. We included all the patients who were ≥18 years of age and consecutively diagnosed with COVID-19 between the 1st of May 2020 to 31st July 2020. Patients were interviewed by a physician using a semi-structure questionnaire. Data were collected on socio-economic status, occupation, income loss, leaves taken, decrease in work efficiency (self-perceived) and about-facing any stigma/discrimination at the workplace.

Results:
Out of 245 patients, 190 patients were employed. A total of 126 patients (66.3%) self-reported their work was affected due to COVID-19 disease. A total of 30.5% of patients (n = 58/190) reported deduction in their salary. The median amount of salary loss was INR 10,000 (IQR 9000–25000). Decrease in income and work efficiency (self-perceived) was found to be 37.3% (n = 71) and 12.1% (n = 23), respectively. A total of 47 patients (37.3%) took personal leaves (median number – 17 days (IQR 14–25), and discrimination/stigma related to the COVID-19 at the workplace was faced by 22.6% of patients.

Conclusion:
Income and work of a substantial number of patients was affected due to COVID-19, as there was a decrease in income and work efficiency. Patients also had to take personal leaves and face stigma in the workplace. This will inform the policymakers to formulate strategies to mitigate the impact of COVID-19.

Published: August 2021

Background and Aim:
Inadequate nutrition during fetal development resulting from poor dietary habits leads to reprogramming within fetal tissues and poses as a risk factor for non-communicable diseases in later life. This study was conducted to determine the dietary habits, diversity, and predictors among pregnant women in Lagos, Nigeria.

Methods:
A descriptive cross-sectional study was conducted using a structured interviewer-administered questionnaire to obtain data from pregnant women attending primary health care centers in Lagos, Nigeria. A multistage sampling method was used to select 350 pregnant women. A food frequency questionnaire was used to assess the dietary habits while dietary diversity was measured using non-quantifiable 24-hour recall. Data were analyzed using Epi-Info version 7.2 computer software. Chi-square and t-test were used to test for associations and P value < 0.05 was considered to be statistically significant.

Results:
Only 16.7% of respondents consumed five servings of fruits and vegetables daily while the rice was the most frequent meal taken (45.4%). Meat was the commonest animal protein (20.3%) and only 30.8% had a high dietary diversity score (DDS). High DDS was significantly associated with parity of 1–3, living in a duplex or detached house, completion of at least secondary school education, and highly skilled professionals.

Conclusion:
Healthy dietary habits and high DDS were low and associated with low parity and higher socio-economic status. Nutrition intervention that encourages higher dietary diversity is needed especially among women of higher parity and lower socioeconomic status in Lagos.

Purpose:
This study assessed “model of care” (MoC) knowledge among Riyadh First Health Cluster (C1) staff (health workers and admin) at Saudi Arabia's Ministry of Health (MOH).

Methods:
This study is cross-sectional, observational, and analytic. Raw data were collected from the data warehouse of the Vision Realization Office (VRO) at the MOH. It was then entered into SPSS, Version 24, and 3,696 individuals were analyzed. Descriptive statistics were presented as numbers and percentages, and a Chi-square test was used to test for associations. The study was approved by the hospital research committee and the Institutional Review Board (HlRI-15-Dec l9-01).

Results:
The staff who knew of the transformation occurring in the healthcare sector were 98.2% male and 93.6% female (P < .001). The staff having more than 20 years of experience represented the highest level of understanding (44.4%). In contrast, a team with 0–1 years of experience had the lowest level of understanding (13.6%) (P < .001). However, the staff with 0–1 years of experience was associated with the highest agreement percentages (93.4%, 92.2%) while the staff with more than 20 years of experience was associated with a lower agreement of percentages (88.2%, 79.1%) (P < .001). Finally, we found pharmacists and primary healthcare centers to generally have the highest knowledge percentages across the studied dimensions (P < .001).

Conclusion:
The C1 staff who participated in this study had good knowledge of Saudi Arabia's MoC. We recommend future elaborating research about the Saudi MoC to compare in detail with the staff in the other sectors and reach an international benchmark.

Published: August 2021

Objective:
Studies assessing prevalence and risk factors of abdominal hernia are scarce in Saudi Arabia, that is why this study aimed to find out the prevalence and risk factors of abdominal hernia among the Saudi Population in 2020.

Methods:
A cross-sectional study was done on 500 participants. A pre-designed questionnaire included three sections: Section A consisted of sociodemographic, Section B had items for three dimensions: pain at the site of the hernia or the hernia repair, restriction of activities, cosmetic discomfort; Section C included medical history and other associated risk factors of hernia.

Results:
The prevalence of abdominal hernia in our study was found to be 38.8%. The participants in 18-25 years had less prevalence (21.2%). participants with BMI >25 (Overweight and Obese) had higher prevalence than others. The mean EuraHS-QoL score in participants who had abdominal hernia was significantly higher than patients who didn't have AH. Age >40 years, male gender, BMI >25, congenital anomalies, history of abdominal surgery, history of abdominal trauma, family history, grand multipara, chronic cough, chronic bronchitis, and smoking were potential predictive factors of AH.

Conclusion:
Abdominal hernia is a common problem in Saudi Arabia. Abdominal hernias are more common in men than women, there is an obvious relationship between obesity, history of abdominal surgery, history of abdominal trauma, family history and hernias. Early diagnosis, easily accessible health facilities and health education are important to prevent complications and improve quality of life.

Background:
Cancer is one of the leading causes of death in the pediatric age group following infections. Among the diagnostic modalities, fine needle aspiration cytology (FNAC) is increasingly recognized as it permits rapid diagnosis with low cost and complication. In this study, we emphasize the diagnostic value of FNAC and describe the cytomorphological spectrum of tumors diagnosed on FNAC in pediatric patients with or without the aid of ancillary tests.

Materials and Methods:
This retrospective study included a total of 614 patients under the age of 15 years for whom fine needle aspiration (FNA) was done during a period of 3 years with or without guidance. The cytology smears were reviewed, and the morphological spectrum was analyzed with the ancillary studies.

Results:
Aspirates from children constituted around 3.5% of the total FNAC performed in our Institute. Of the 614 cases, 336 were male, and 278 were female with age under 15 years. Neoplastic cases constituted around 72%, which included benign (2%) and malignant (98%) tumors. The spectrum include hematolymphoid neoplasms in 39.3%, small round cell tumors (SRCT) in 24.9%, Wilms tumor in 9.2%, germ cell tumors in 4.8%, spindle cell neoplasms in 4.8%, hepatoblastoma in 3.2%, and osteosarcoma in 3% of the cases. The metastatic lesions constituted 8.1% of the cases diagnosed by FNA.

Conclusion:
FNA proves to be a reliable and efficien modality in diagnosing pediatric neoplasms in the hands of a skilled cytopathologist.

SOCIO-ECONOMIC FACTORS AFFECTING FOOD SECURITY AMONG THE ELDERLY. A CRITICAL LITERATURE REVIEW
Authors: Njeri Arianna 
Published: August 2021

Purpose: Mobile technologies provide an affordable and easily accessible technology that lecturers can use effectively to assist students with their studies. The general objective of the study was to evaluate socio-economic factors affecting food security among the elderly.
Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps.
Findings: From the study findings, it is concluded that the households of the elderly persons are faced with abject poverty due to the household structures they live in, which lack food storage facilities hindering food utilization. The elderly persons are faced with health challenges that hinder them from accessing adequate and appropriate foods. They also are not able to use the available types of food due to the ailments they suffer. Elderly persons are faced by various levels of food insecurity due to the deteriorating strength and vulnerability that comes handy with aging. Farming practices by elderly persons depict that they mainly use manual labour limiting their food production. The elderly persons food utilization that entails enlightenment on food production based on food storage, feeding habits and farming methods have lowered food production thus food insecurity.
Recommendations: The study recommended that there should be established programmes that provide homes for the aged to cater for the elderly persons who live alone, sickly and too aged to undertake their daily domestic duties. In addition feeding programmers in households with elderly persons should be formulated and implemented. Relatives should be encouraged to follow up on the wellbeing of their aging parents and organize to employ care givers to keep up domestic duties that may be making it difficult for the elderly to access food. The ministry of special programmes should consider provision of relief food to households with the elderly persons who suffer severe food insecurity. They should also collaborate with the ministry of education in ensuring children who are under the care of aged people have a school feeding programme to provide at least a meal for them at school.

Published: August 2021

Energy is an important aspect for all countries. Due to the overexploitation of resources, nonrenewable resources, such as fossil fuels, are depleting day by day. This calls for alternative power sources, such as wind energy. Wind energy is a clean and inexhaustible source of energy. One of the ways of harvesting this energy is using wind turbines, which transform the kinetic energy of wind into electrical power output. Wind turbines face many problems, such as low wind hours, design issues, and so on.
The main focus of this work is to find the optimum blade angle of turbine blades, in order to produce the maximum power output, even at low wind hours. In this study, CFD analysis is done on a 5 MW wind turbine blade at wind velocities 3, 12.5 and 25 m/s, which are the cut in, rated, and cut out velocities of wind turbines, respectively. The range of angles under consideration varies from 20 to 89 °. A 3D model of the blade is analyzed using ANSYS Fluent 19.0. The optimum blade angle is identified, and the characteristics of the curves of blade angles, with respect to different parameters, are obtained.
HIGHLIGHTS

Optimum Blade angle for better moment
Pressure and velocity Characteristics at various blade angles
5MW HAWT blade moments for wind velocity of 3,12.5 and 25 m/s
The maximum moment is obtained at an angle 82 degree at various wind velocities

Published: August 2021

The strengthening and retrofitting of concrete structures are becoming an essential part of the building and its structures. When the building comes of age, there is a need to increase the structural members' strength, life, and resistivity against unfavorable environmental conditions. In the current scenario, ferrocement composites are used for structural strengthening and rehabilitation. Therefore, an experimental investigation is needed to evaluate the effectiveness of the strengthening on the square and circular reinforced concrete columns by ferrocement and micro concrete materials. The experimental results showed that the ferrocement and micro concrete techniques enhanced the stress-strain behavior and displacement limit of the square and circular RC column. The strengthening circular RC column by micro concrete gives a better performance in stress-strain behavior and displacement limit. In addition, the ferrocement and micro concrete strengthening technique is a promising and economical alternative compared to the other strengthening techniques. Also, test results were compared with ACI and CNR–DT representative load-carrying models to verify each model's reliability and accuracy. Furthermore, the TOPSIS method was adopted to find out the best solution for square and circular columns, and cost analysis was carried out.
HIGHLIGHTS

RC columns were strengthened using ferro cement and micro concrete
RC Columns under compressive concentric load were tested
Micro concrete strengthening controls deflection and enhances the load capacity of columns
The analytical approach of TOPSIS was used to find the best solution

Abstract. Commercial microwave links (CMLs) in telecommunication
networks can provide relevant information for remote sensing of
precipitation and other environmental variables, such as path-averaged
drop size distribution, evaporation, or humidity. The CoMMon field experiment (COmmercial Microwave links for urban
rainfall MONitoring) mainly focused on the rainfall observations by monitoring a 38 GHz dual-polarized CML of 1.85 km path length at
a high temporal resolution (4 s), as well as a co-located array of five
disdrometers and three rain gauges over 1 year. The dataset is
complemented with observations from five nearby weather stations. Raw
and pre-processed data, which can be explored with a custom
static HTML viewer, are available at
https://doi.org/10.5281/zenodo.4923125 (Špačková et al., 2021). The data quality is generally
satisfactory for further analysis, and potentially problematic measurements are flagged to
help the analyst identify relevant periods for specific study purposes. Finally, we encourage potential applications and discuss open issues
regarding future remote sensing with CMLs.

Published: August 2021

The demand for natural products, which are rich in biologically active compositions, grows constantly. The choice and production of such products can minimize the deficit of importance for human organism components, which are contained only in plant food. The paper contains the laboratory studying results of the chemical composition of the fruits of two Actinidia Lindl. cultivars of Federal State Budgetary Scientific Institution Federal Horticultural Research Center for Breeding, Agrotechnology, and Nursery (FSBSI FSC for Horticulture) genetic collection: Actinidia kolomikta (Rupr. et Maxim.) Maxim. and Actinidia polygama (Siebold et Zucc.) Maxim. All the presented samples are grown in field conditions. The fruits were picked up in the phase of harvest maturity while ripening. The data on antioxidant activity of water and methanol extracts, the content of phenolic compounds sum, soluble solids, and titratable acids in the fruits, and on qualitative composition of secondary metabolites (organic acids, fatty acids, mono-, di- and polysaccharides) are given in the paper. The variation limits of the parameters under study depending on the sample are presented. As a result of the laboratory studies, it was stated that A. kolomikta fruits 10 times exceed A. polygama fruits on all the stated parameters. Only the results on the soluble solids content in the fruits of both cultivars are approximately at the same level (A. kolomikta > A. polygama on 1.16%). The positive correlation between antioxidant activity and the general content of polyphenols is confirmed at both cultivars. Actinidia kolomikta genotypes Chempion and Lakomka and Actinidia polygama ones Tselebnaya and Uzorchataya showed the best results. The correct individual choice of actinidia fruits that are the best ones at the biochemical composition and the content of micronutrients allows supplying the consumers with food products.
