Authors: Thambireddy Supriya , Nirmala SVSG , Nuvvula Sivakumar
Published: November 2023

Introduction: Bowlby suggests that children develop internal working models in earlier stages depending on their attachment relationships with parents. In paediatric dental clinics, children tend to display various behaviours depending on their attachment style, which can affect the communication and treatment outcomes with the child dentist. Aim: To determine the prevalence of attachment styles in 9 to 12 years old school children and to assess the association of attachment styles with the age and gender of the children. Materials and Methods: A descriptive cross-sectional study was conducted on a total of 384 school children aged 9 to 12 years, in the Nellore district using the cluster sampling method. Attachment styles were measured using a 15-item questionnaire developed from the Attachment Questionnaire for Children (AQ-C). The children were instructed and then asked to read and rate the extent to which each questionnaire item described themselves. Data were analysed statistically using the chi-square test for prevalence of attachment styles, Pearson correlation, and multiple regression analysis for age and gender associations. The level of significance was set at p≤0.05. Results: The study found that 64.10% (n=246) of all participants exhibited a secure attachment style, while 7% (n=27) and 28.9% (n=111) displayed avoidant and ambivalent attachment styles, respectively. Age showed a significant association with secure (p=0.006) and ambivalent (p=0.026) attachment styles. However, gender did not show any association with attachment styles. Conclusion: The study concluded that the secure attachment style was the most prevalent, followed by ambivalent and avoidant attachment styles, regardless of gender. Age was found to be significantly associated with secure and ambivalent attachment styles.

Authors: Noah Kufre , Anagboso Martin O. , Iyanyi Uchechukwu L. , Ajaghaku Daniel L. , Okokon Jude E.
Published: November 2023

Aim: The antidotal potential of Hippocratea africana root, which is used locally to cure poisoning, was studied in rats.

Methodology: The hepatoprotective activity of the root extract (200-600 mg/kg), fractions (dichloromethane (DCM) and aqueous, 400 mg/kg) and Silymarin (100 mg/kg), were investigated against paracetamol-induced liver injury in rats. Assay of liver function parameters, markers of antioxidative stress in addition to liver histological analysis were employed to evaluate the hepatoprotective potential of root extract and fractions.

Results: Administration of the root extract (200-600 mg/kg) caused significant (P < .05-.001) increases in the blood levels of total protein and decreases in direct and total bilirubin, and the liver biomarker enzymes ALT, AST, and ALP caused by paracetamol administration.  Most of the time, the effects were dose-dependent. When compared to the negative control group of animals (organotoxic-treated animals), the histology of the liver sections from animals treated with extract, fractions, and silymarin revealed a decrease in pathological characteristics. These histological observations suggest significant hepatoprotective potentials which were in line with the chemical pathological alterations.

Conclusion: The outcome of the study indicated that root extract and fractions of Hippocratea africana have antioxidative stress potentials and hepatoprotective action against harmful substances, maybe as a result of its phytochemical constituents' activity.

Authors: Nabi Muhammad Mutie Un , Shahid Muhammad , Shahzadi Kiran , Basit Muhammad Abdul , Ali Abid , Hussain Zunaira , Ali Qurban
Published: November 2023

Abiotic stressors include things like heat, cold, drought, and salt that plants have to withstand. These are the main and ongoing agricultural challenges that lower crop production. In the end, modifications to components, nutrient control, and biosynthetic ability hinder or even stop plant development. Stress is an environmental factor that, in terms of genetics, prevents full genetic expression. These markers are divided into many types based on their intended use: Simple sequence repeat (SSR) markers are a great tool for determining stress tolerance, but RAPD (random amplified polymorphic DNA) markers are useful for identifying and screening hybrids based on salinity and drought stress resistance. These markers are also necessary for the QTL (Quantitative Trait Loci) mapping of genes linked to stress. These ancestor genes control the production of dehydrins and saltol in response to dryness and salinity, respectively. DNA markers enable the use of innovative approaches and marker modification in marker-assisted breeding to increase tolerance to abiotic stress.

Authors: Gujre Shruti , Mishra Vikash Prasad , Tilwari Anita , Azad Anand Rao , Kher Deepak
Published: November 2023

In the Rabi season of 2022, a comprehensive agricultural experiment was conducted at the Instructional Farm of the Department of Agronomy, located within the Faculty of Agriculture at SAGE University in Bhopal, Madhya Pradesh. The primary objective of this experiment was to assess the influence of varying levels of phosphorus, in conjunction with the application of Phosphorus Solubilizing Bacteria (PSB), on the growth and yield parameters of field pea. This research was undertaken using a randomized block design, with a factorial arrangement that was replicated three times to ensure the reliability and robustness of the findings.

The experiment encompassed seven distinct treatment combinations, which spanned the spectrum from a control group to different percentages of the recommended dose of phosphorus (RDF), including 100%, 80%, 60%, 40%, and 20% of the RDF. The results obtained from this meticulous study unveiled significant impacts of phosphorus levels and the application of Phosphorus Solubilizing Bacteria on several critical growth and yield parameters of field pea. The effects of these factors were observed at multiple stages of the plant's growth, particularly at 30, 60, and 90 days after sowing (DAS). The treatment combination that included 30:60:30 kg per hectare of phosphorus and 200 g per hectare of PSB exhibited outstanding results, with the maximum plant height at 30, 60, and 90 DAS, registering measurements of 39.29 cm and 59.29 cm, respectively.

Remarkably, this specific treatment regimen also led to the highest number of branches per plant at both 60 and 90 DAS, with impressive counts of 7.80 and 9.20 branches, respectively. Furthermore, the combined impact of phosphorus and Phosphorus Solubilizing Bacteria had a profound influence on key yield parameters. Notably, the treatment featuring the combination of 30:60:30 kg per hectare of phosphorus and 200 g per hectare of PSB resulted in the highest values for critical yield parameters, such as the number of pods per plant (17.59), seed yield per hectare (1070 kg), and straw yield per hectare (2142 kg). These findings underscore the pivotal role of this specific treatment regimen in enhancing crop productivity and maximizing overall yield. The results of this experiment offer valuable insights into optimizing phosphorus management practices in the cultivation of field pea, ultimately contributing to improved agricultural sustainability and food security in the region. This research serves as an important contribution to the field of agronomy and provides practical guidance for farmers and researchers alike.
Photovoltaics: Panacea to Africa Sustainable Development
Authors: Okoro Ugochukwu Kingsley
Published: November 2023

African countries are falling behind in attaining the sustainable development goals. They are in dire need of electricity, which had been declared the essential tool to achieve most goals, to meet their population’s utilizable energy requirement. With renewables being globally adopted energy options to save the changing climate and preserve the environment and biodiversity, photovoltaic (PV) is advocated to remedy the energy deficiency for sustainable development. All over Africa indicates viability in PV energy owing to the incident global solar radiation (Gh). Nigeria being a case study shows awareness of PV energy, which has manifested in the attitude towards its penetration and the expected benefits. With the anticipated threat of climate change on PV performances, the projected incident Gh across Nigeria has shown two epochs which are yet viable for PV energy by the year 2100. Foreseeable challenges in the PV penetration and investments have been presented as wrongdoings and whistleblowing is advocated as the policy that will ensure the PV penetration for sustainable development.

Published: November 2023

The main objective of this study, as mentioned on the title, is to determine whether there is any effect of music on physical task performance. Three different kind of music were used in this study: easy listening/slow music, hard rock music, and subject's own favorite music. The same physical task without music was also conducted for every subject as the control. To simulate the physical task, each subject has to walk on a treadmill at a constant speed (3 MPH) and inclination (4º) for six minutes. Enough rest was given after a subject finished each task. Four undergraduate and six graduate students were volunteered as subjects in this study. They are three females and seven males. Statistical analysis software programs were used to analyze the results. It is shown from this study that slow music and favorite music have significant effect on the physical task. The heart rate is significantly lower when the subjects listened to a slow music or their favorite music while performing a physical task compared with performing the same task without listening to any music. The heart rate is not significantly different when subjects listened to hard rock music compared with no music listened. On the other hand, VO2 consumption is not significantly different between without music and with all kind of music. Therefore, according to this study, it is beneficial to listen to a certain kind of music while performing a physical task since they lower the heart rate.

Published: November 2023

The management of supermarket usually has some assumptions about the customers' expectation. Sometimes these assumtions do not reflect the nature of customers' expectations. Because of this miss perception, the supermarket looses its profit and becomes inefficient. This research was carried out in order to find out the customers' expectation on facilities and services of the supermarkets according to the servqual dimensions. The outcomes will be mapped into Kano categorizations. The researcher asked the customer dan manager of four supermarkets to fill the prepared questionnaires. Based on the result of customers' questionnaires, tangible, reliability and assurance dimensions were categorized as one dimensional. While responsiveness and emphaty dimensions were categorized as indifferent. Based on the result of managers' questionnaires, all servqual dimensions were categorized as one dimensional. After comparing the results of customers' and managers' questionnaires, there are three of four supermarkets which are match each other.

Abstract in Bahasa Indonesia :

Manajemen supermarket pada umumnya memiliki asumsi-asumsi mengenai harapan konsumen yang belum tentu sama dengan harapan konsumen sesungguhnya.

Role of Patient Sorting in Avoidable Hospital Stays in Medicare Advantage vs Traditional Medicare
Authors: Xu Jianhui (Frank) , Anderson Kelly E. , Liu Angela , Miller Brian J. , Polsky Daniel
Published: November 2023

Importance

Unlike traditional Medicare (TM), Medicare Advantage (MA) plans limit in-network care to a specific network of Medicare clinicians. MA plans thus play a role in sorting patients to a subset of clinicians. It is unknown whether the performance of physicians who treat MA and TM beneficiaries is different.

Objective

To examine whether avoidable hospital stay differences between MA and TM can be explained by the primary care clinicians who treat MA and TM beneficiaries.

Design, Setting, and Participants

This was a cross-sectional study of a nationally representative sample of MA and TM beneficiaries in 2019 with any of 5 chronic ambulatory care–sensitive conditions (ACSCs). The relative risk (RR) of avoidable hospital stays in MA compared with TM was estimated with inverse probability of treatment-weighted Poisson regression, both without and with clinician fixed effects. The degree to which the estimated MA vs TM difference could be explained by patient sorting was calculated by comparing the 2 RR estimates. Data were analyzed between February 2022 and April 2023.

Exposure

Enrollment in MA.

Main Outcome and Measures

Whether a beneficiary had avoidable hospital stays in 2019 due to any of the ACSCs. Avoidable hospital stays included both hospitalizations and observation stays.

Results

The study sample comprised 1 323 481 MA beneficiaries (mean [SD] age, 75.4 [7.0] years; 56.9% women; 69.3% White) and 1 965 863 TM beneficiaries (mean [SD] age, 75.9 [7.4] years; 57.1% women; 82.5% White). When controlling for the primary care clinician, the RR of avoidable hospital stays in MA vs TM changed by 2.6 percentage points (95% CI, 1.72-3.50; P < .001), suggesting that compared with TM beneficiaries, MA beneficiaries saw clinicians with lower rates of avoidable hospital stays. This effect size was statistically significant to explain the 2% lower rate of avoidable hospital stays in MA than in TM.

Conclusions and Relevance

In this cross-sectional study of MA and TM beneficiaries, the lower rate of avoidable hospital stays among MA beneficiaries than TM beneficiaries was attributable to MA beneficiaries visiting clinicians with lower rates of avoidable hospital stays. The patient sorting that occurs in MA plays a critical role in the lower rates of avoidable hospital stays compared with TM.
mRNA SARS-CoV-2 Vaccination Before vs During Pregnancy and Omicron Infection Among Infants
Authors: Goh Orlanda , Pang Deanette , Tan Janice , Lye David , Chong Chia Yin , Ong Benjamin , Tan Kelvin Bryan , Yung Chee Fu
Published: November 2023

Importance

Infants younger than 6 months are at risk of severe SARS-CoV-2 infection. Data are lacking on the optimum timing for maternal vaccination and estimated effectiveness against Omicron variants, including XBB, for infants.

Objective

To investigate maternal vaccination against Omicron variants, including XBB, and the association of vaccination timing during pregnancy vs prior to pregnancy and risks of SARS-CoV-2 infection among infants aged 6 months or younger.

Design, Setting, and Participants

This population-based cohort study was conducted between January 1, 2022, and March 31, 2023. Singapore’s national dataset was used to study infants born at greater than 32 weeks’ gestation between January 1, 2022, and September 30, 2022. The study included infants whose parents had a confirmed SARS-CoV-2 infection from the date of birth up to 6 months of age. Of 21 609 infants born during this period, 7292 (33.7%) had at least 1 parent infected with SARS-CoV-2 before the age of 7 months. Statistical analysis was performed from April to July 2023.

Exposure

Infants’ mothers were unvaccinated, vaccinated prior to pregnancy, or vaccinated with a messenger RNA (mRNA) SARS-CoV-2 vaccine during pregnancy.

Main Outcome and Measure

Infants were considered infected if they had a positive polymerase chain reaction test.

Results

Among 7292 infants included in this study, 4522 (62.0%) had mothers who were Chinese, 527 (7.2%) had mothers who were Indian, 2007 (27.5%) had mothers who were Malay, and 236 (3.2%) had mothers who were other ethnicity; 6809 infants (93.4%) were born at full term, and 1272 infants (17.4%) were infected during the study period. There were 7120 infants (97.6%) born to mothers who had been fully vaccinated or boosted as of 14 days prior to delivery. The crude incidence rate was 174.3 per 100 000 person-days among infants born to mothers who were unvaccinated, 122.2 per 100 000 person-days among infants born to mothers who were vaccinated before pregnancy, and 128.5 per 100 000 person-days among infants born to mothers who were vaccinated during pregnancy. The estimated vaccine effectiveness (VE) was 41.5% (95% CI, 22.8% to 55.7%) among infants born to mothers vaccinated during pregnancy. Infants of mothers who received vaccination prior to pregnancy did not have a lower risk for infection (estimated VE, 15.4% [95% CI, −17.6% to 39.1%]). A lower risk for Omicron XBB infection was only observed among mothers vaccinated with the third (booster) dose antenatally (estimated VE, 76.7% [95% CI, 12.8% to 93.8%]).

Conclusions and Relevance

In this population-based cohort study, maternal mRNA vaccination was associated with a lower risk of Omicron SARS-CoV-2 infection among infants up to 6 months of age only if the vaccine was given during the antenatal period. These findings suggest that mRNA vaccination during pregnancy may be needed for lower risk of SARS-CoV-2 infection among newborns.
