Earth, gender and food security: Maria Zaloumis’ journey of feminising Agric-business in Zambia
Authors: Mwale Nelly 
Published: May 2023

This article explores the interconnectedness of the earth, gender and food security in the Zambian context using the narrative of Maria Zaloumis (a female Zambian farmer) in the public sphere. It draws on a narrative research design by the restorying of Maria’s trajectory in Agric-business as informed by the African ecofeminist theory. The study shows that Maria was described as an emerging young farmer and an emblem of female entrepreneurship. Her trajectory mirrored the intersection of the earth, gender and food security through her portrayal as a woman who endured life tragedies of losing a child, and being a victim of gender-based violence in her marriage. She drew inspiration from her mother (venturing into farming was linked to her mother), the earth (farming was an outlet for healing from her marital challenges) and religion (attributed her success to God as a member of the Baptist church). Maria’s account which resonates with the injustice suffered by the earth and shared by women through the environmental crises affirms that in the midst of suffering, women could still contribute to food security by turning a crisis into an opportunity and fostering a life-affirming theology.Contribution: The article contributes to scholarship on the earth, gender and food security by bringing to the fore the ways in which women have contributed to changing the Agric-business landscape through the intersection of the earth, gender and religion from the Zambian context. It also adds a new perspective to women’s empowerment and the preservation and stewardship of mother earth.
Is periodontal infection a risk factor for thromboembolic disease? A systematic review
Authors: Devi Oinam Monica , Gupta Jyoti , Chahal Gurparkash Singh , Jain Ashish 
Published: May 2023

Background:
Venous thromboembolism (VTE) is a rising major health problem comprising pulmonary embolism (PE) and deep vein thrombosis. It is of concern due to premature mortality, increased morbidity, and associated healthcare costs and hospitalization. Periodontitis can increase the risk of VTE by way of systemic inflammation induced by infection that can contribute to hypercoagulability and platelet aggregation. This systematic review aims to synthesize all the evidence concerning periodontal infection as a risk factor for thromboembolic disease.

Materials and Methods:
A search for articles published from 1967 till December 2020 was conducted in the PubMed (MEDLINE), Scopus, and EMBASE data bases.

Results:
Five hundred and five articles were retrieved after running search strategies in PubMed, Scopus, and EMBASE search databases. Based on the inclusion criteria, three clinical studies, two case series, and ten case reports were included for qualitative analysis. The presence of periodontal disease was reported to influence the occurrence of venous thromboembolic disease with a statistical significance of <0.010. Case series and case reports of septic PE due to periodontal disease showed complete resolution of lung lesions and subsiding of symptoms after dental treatment and antimicrobial therapy.

Conclusions:
The results of this systematic review suggested for an association between periodontal disease and the incidence of thromboembolic disease. As most of the included/available studies are case series and case reports, the strength of evidence is weak. Evidence generated from well-designed longitudinal controlled clinical trials may be helpful to further assess the strength of the association.

Avocado is a healthy fruit and the consumption is continuously growing worldwide. The fruit contains polyphenolic compounds with antioxidant effects. Globally, research has been devoted to exploring the fruit quality, especially compounds with antioxidant effects, from different avocado-growing sites. However, the fruit quality of the Tanzanian avocado has so far not been investigated. In this study, the contents of polyphenols in peel, pulp and seed of avocados sampled in south-western Tanzania are described. The levels of total polyphenolic and flavonoid contents were measured, and antioxidant activity was evaluated using a 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The total polyphenolic content was highest in the seed and lowest in the peel (424 and 200 mg GAE/100 g DW, respectively). As for the total flavonoid content, the pulp had the highest value of 36.98 mg RE/100 g DW, while the seed had the lowest value of 32.54 mg RE/100 g DW. The overall average half maximal effective concentration (EC50) values in decreasing order, corresponding to an increasing antiradical activity, were 4.90 (peel), 3.63 (seed) and 3.24 µg/mL (pulp). The seed and peel possessed high levels of total polyphenolic and flavonoid content, thus demonstrating substantial antioxidant capacity. Seed and peel can potentially be processed and included in the diet to provide inexpensive antioxidant ingredients of natural origin. Consumption of the seed will not only improve human health but also reduce the environmental pollution, as many thousand tonnes of avocado seeds are produced in Tanzania per year; a huge amount currently remains as waste.

Published: May 2023

The access to electricity is still not reliable in Tanzania. Whilst, there are several locations within the country that have wastewater cites that are not economically used to produce electricity. At the University of Dar es Salaam (UDSM), there are main grid power, and few scattered solar panels. This study was intended to bridge the divide between the current increasing power demands of the UDSM by exploiting not so much used sources, such as electric energy from wastewater. This study was undertaken to develop a Microbial Fuel Cell (MFC) prototype fed by sewage in Dar es Salaam, for electricity generation using cost effective materials for the cathode compartment. The collection of samples took place using sewage substrates from the UDSM oxidation ponds. The untreated sewage was collected from oxidation ponds. Preliminary experiments were carried out to identify the cathode and substrate that produced better results in terms of volts and current output. Aluminium produced the most desirable results compared to copper, stainless steel and mild steel in all the substrates. On the other hand, untreated sewage with aluminium/carbon electrodes produced higher voltage and current compared to treated sewage with the same electrodes. Thereafter, a prototype of the MFC was developed by connecting three single chambered cells in series of 628 cm3 volume of untreated sewage with aluminium and carbon electrodes. The prototype generated a stable voltage of 1.73 V and a current of 0.07 mA recorded for a period of one hour. The power generated was enough to light a 6.25 mW LED bulb of 25 mA across a 100 Ω resister. Therefore, untreated sewage produced more power in MFCs with aluminium/carbon electrodes compared to the other tested materials.

Authors: Hakami Emad , Alsomali Ahlam , Senitan Mohammed 
Published: May 2023

Background: Healthcare workers in direct contact with confirmed COVID-19 patients often face a negative impact on psychological health. This study aims to examine the prevalence of anxiety and depression among nurses caring for COVID-19 patients.
Methods: A cross-sectional survey was conducted during the COVID-19 pandemic from January 2022 to April 2022 at King Faisal Specialist Hospital and Research Center in Riyadh, Saudi Arabia. The prevalence of depression and anxiety was assessed using the Patient Health Questionnaire (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7) questionnaire. Kruskal–Wallis’s test was used to compare the total scores of the PHQ-9 and GAD-7 with respect to demographic characteristics. P<0.05 was considered statistically significant.
Results: A total of 123 nurses were included in the study. Most of them were females (69.92%), aged 30–39 years (45.53%), had a bachelor's degree in nursing (75.61%), and had more than ten years of experience (3830.89%). The depression and anxiety prevalence in the study was 78.1% and 72.4%, respectively. Nurses aged 30–39 years were significantly associated with depressive symptoms. Female nurses showed significantly higher scores for depression and anxiety than males 74.42% and 67.45%, respectively.
Conclusion: The findings suggest that nurses are at risk for developing depression and anxiety. Therefore, regular mental health screening is necessary for nurses, particularly during a pandemic.

Introduction: One of the satellite imagery analysis companies, Head Of Simularty, based in the United States, found that there has been pollution to the marine environment in the South China Sea area, precisely in the Spratly Islands, namely the coral island of Whitsun Reef which is still part of the Exclusive Economic Zone of the Philippines.Purposes of the Research: Aims to find out and analyze the regulation of international law on pollution in the South China Sea and to find out and analyze the form of accountability of the Chinese State due to marine pollution carried out under international environmental law. Methods of the Research: This legal research uses normative juridical research, case approach, statutory approach, and conceptual approach, primary and secondary legal materials, legal material procedures using primary legal materials which are then associated with secondary legal materials and processing and analysis of legal materials using qualitative descriptive analysis.Results of the Research: The results showed that China had violated international environmental law obligations as stipulated in the Stockholm Declaration 1972, Rio Declaration 1992, UNCLOS 1982 and MARPOL 73/78. Furthermore, marine pollution carried out by the State of China in the territory of the Exclusive Economic Zone of the Philippine State has opposed the provisions of international environmental law as stipulated in the 1972 Stokcholm Declaration and UNCLOS 1982 which states that it prohibits any country from taking acts of pollution against the environment against both its own territory and in the jurisdiction of other countries. Therefore, it is necessary to have accountability efforts that must be carried out due to the pollution actions carried out.

Subjective Age and Health Care Avoidance Among Aging Men Living With or Without HIV
Authors: Seau Quinn , Ware Deanna , Plankey Michael W. 
Published: May 2023

Introduction Negative aging perceptions have been shown to influence one’s health care–seeking behaviors; this relationship has not been studied among middle-aged and aging adults living with HIV. The current study uses data from the Multicenter AIDS Cohort Study (MACS) to investigate the association between subjective age and health care avoidance. Objective To examine the hypothesis that adults living with HIV who perceive themselves as older, after adjustment for covariates, would be more likely to avoid care than their HIV-negative counterparts who perceive themselves as older. Methods The MACS is a prospective study of more than 7000 sexual minority men living with and without HIV from 4 metropolitan US areas. The Understanding Patterns of Healthy Aging in Men Who Have Sex With Men sub-study of the MACS was conducted from April 2016 to March 2019. Current analyses use cross-sectional data on 1118 participants from this sub-study from October 2016 to March 2017. Logistic regression was used to produce odds ratios and 95% CIs examining the association between subjective age and health care avoidance. Covariates included age, HIV status, race and ethnicity, education, and comorbid conditions. Further analyses were conducted among persons living with HIV, which included CD4 counts and viral load detection as covariates. Results In the full sample and sample of people living with HIV, after adjustment for covariates, there was a positive association between older subjective age and health care avoidance and a negative association between younger subjective age and health care avoidance, albeit both not statistically significant. Living with HIV was positively associated with health care avoidance, but not statistically significant. Conclusions Future studies with larger sample sizes are needed to elucidate the significance of subjective age and health care avoidance. Aside from the pivotal role of health care avoidance, the field of HIV and aging may benefit from identifying other psychological, physiological, and behavioral mechanisms by which perceptions of aging influence health.

ÖZET
Dili, düşünceyi ve mantığı yepyeni bir perspektifle ele alan Yalçın Koç, Batı ve İslam felsefelerinde şimdiye kadar dil, düşünce ve mantık alanlarında yapılan çalışmaların sadece önermesel dille sınırlı kaldığını, halbuki dil ve dolayısıyla mantığın katmanlı (Koç’un deyimiyle, arkitektonik) bir yapıya sahip olmasından dolayı dilin bu katmanlar çerçevesinde ele alınması gerektiğini düşünür. Koç’a göre önermesel dil, dil arkitektoniğinin sadece belli bir katmanını oluşturur ve bu anlamda diğer katmanlarla varoluşsal bir ilişki içerisindedir. Bu makalede, Koç’un dilin mahiyeti, sınırı, zemini ve kaynağına dair görüşünü, onun katmanlı (arkitektonik) dil anlayışı çerçevesinde ele almaya çalışacağız.

Authors: Wang Zichuan 
Published: May 2023

This paper introduces Fermat’s little theorem (FLT), which says that any integer raised to power is congruent to modulo . This paper will give several proofs of FLT, using methods including number theory and group theory, together with generalizations of FLT in different directions. FLT is an important result in number theory and group theory. It has multiple generalizations and corollaries, and one of its corollaries is the foundation of RSA cryptography. The effort made trying to prove FLT stimulated researches in many fields in mathematics, and FLT is crucial and fundamental in research of modern cryptography.
The Effect of Resident Involvement in Hip Fracture Surgery: An Analysis of a Single Institution Before and After the Addition of an Orthopaedic Surgical Residency
Authors: Dutcher Lincoln T. , Helal Asadullah , Doucet Dakota W. , Jones Alan L. 
Published: May 2023

Introduction:
Hip fractures are common injuries that are associated with serious morbidity/mortality in the elderly and represent a substantial financial burden to healthcare systems. Previous studies demonstrated that resident involvement in orthopaedic surgeries is associated with increased surgical time and cost, with equivocal or worse outcomes. This study evaluated outcomes of hip fracture surgery at one institution, before and after the introduction of an orthopaedic residency program.

Methods:
A retrospective chart review divided patients who underwent hip fracture surgery between January 2015 and January 2018 into two groups based on resident involvement. Outcomes including surgical time, length of stay (LOS), readmission rate, and direct/indirect costs were compared as were the American Society of Anesthesiologists physical status score and procedure conducted.

Results:
Six hundred sixty-two hip fracture surgeries were performed in 36 months. Residents were engaged in 303 cases (45.8%) with no notable differences in the two groups regarding American Society of Anesthesiologists score, procedure conducted, or readmission rate. With resident involvement, surgical time was significantly longer (91.2 versus 78.9 minutes, P-value = 0.004), whereas LOS was significantly shorter (5.2 versus 5.6 days, P-value = 0.003). Finally, there were significant reductions in direct costs (8% reduction; P < 0.001) and OR implant costs (12% reduction; P < 0.001), but significant increase in indirect costs (7% increase; P < 0.001).

Discussion:
Surgical experience is critical in orthopaedic training. There are concerns regarding potential negative effects of resident involvement on surgical outcomes and healthcare costs. While resident involvement was associated with slightly increased surgical times and indirect costs, it also led to decreased LOS and direct costs. We believe this is the first study to compare patient outcomes at one institution before and after resident involvement. Our findings demonstrated, compared with attendings alone, resident involvement resulted in an overall improvement rather than compromise in patient care.
