Unmasking of subclinical keratoconus with Descemet membrane endothelial keratoplasty in Fuchs endothelial dystrophy
Authors: Yung Madeline , Li Jennifer Y.
Published: December 2022

We report a case of Fuchs endothelial corneal dystrophy (FECD) with concurrent forme fruste keratoconus (KCN) that was unmasked with Descemet membrane endothelial keratoplasty (DMEK) in the right eye, but not with Descemet-stripping automated endothelial keratoplasty (DSAEK) in the left eye. The patient was a 65-year-old female with FECD who underwent uncomplicated combination cataract surgery and DMEK in the right eye. She subsequently developed intractable monocular diplopia associated with inferior displacement of the thinnest point of the cornea and subtle steepening noted on posterior corneal curvature on Scheimpflug tomography. The patient was diagnosed with forme fruste KCN. Altering the surgical plan to combine cataract surgery and DSAEK in the left eye successfully circumvented the development of symptomatic visual distortion. This is the first case providing comparable data from contralateral eyes in the same patient regarding the outcome of DMEK versus DSAEK in eyes with concurrent forme fruste KCN. DMEK appeared to unmask posterior corneal irregularities and resulted in visual distortion, whereas DSAEK did not. The additional stromal tissue in DSAEK grafts appears to help normalize alterations of the posterior corneal curvature and may be the preferred endothelial keratoplasty for patients with concurrent mild KCN.

Published: December 2022

Background:

Currently, the high expression of fetal hemoglobin (HbF) in sickle cell disease is treated by hydroxyurea (HU). However, potential adverse effect regarding the use of HU is a major concern. Therefore, the search for an alternative therapeutic agent is necessary. By using K562 cells as a model, this research aimed to determine the effect of erythropoietin (EPO) and stem cell factor (SCF) combination therapy on the expression of BCL11A, KLF1, and the ERK of mitogen-activated protein kinase (MAPK) pathway.

Methods:

K562 cells were treated with SCF, EPO, and a combination of SCF and EPO for 24 h. Real-time quantitative polymerase chain reaction was performed to detect γ-globin mRNA expression. Western blotting was performed to determine the expression of BCL11A, KLF1, and ERK of the MAPK pathway.

Results:

In contrast to HU, the treatment with SCF and EPO, either separately or together, preserved the expression of the γ-globin gene. In addition, SCF and EPO treatment had no effect on the expression of BCL11A or KLF1 in K562 cells. After receiving SCF and EPO treatment, the ERK signaling of the MAPK remained unaltered.

Conclusions:

We conclude that the expression of the γ-globin gene, BCL11A, KLF1, and ERK of the MAPK pathway is unaffected by the combination of EPO and SCF.
In silico-based Identification of Some Selected Phytoconstituents in Ageratum conyzoides Leaves as Potential Inhibitors of Crucial Proteins of Blastomyces dermatitidis
Authors: Sakyiamah Maxwell Mamfe , Larbi Evans Boakye , Kwofie Samuel Kojo
Published: December 2022

Background:

Blastomyces
dermatitidis poses health threats to humans due to the frequency of infections (blastomycosis) and the increasing resistance to existing standard antifungal drugs. Moreover, the use of experimental in vitro and in vivo approaches in search for potent drug candidates is costly and time-consuming. The aim of this study was to evaluate the pharmacological properties of some reported phytoconstituents of Ageratum
conyzoides against key enzymes of B.
dermatitidis using in
silico approach.

Methods:

A total of 29 reported bioactive compounds previously isolated from the leaves of A.
conyzoides were randomly selected by a literature survey and their 3D Structure Data File (SDF) structures were downloaded from PubChem database. Applying molecular docking and dynamics simulation techniques, the phytoconstituents (ligands) were docked with the binding ligand pocket of three simulated enzymes; Saccharomyces
cerevisiae lanosterol 14-alpha demethylase, human squalene epoxidase, and thymidylate synthase from Pneumocystis
carinii using AutoDock 4.0 software and the poses that showed lowest binding energies were visualized using LigPlot+.

Results:

The results obtained from the docking studies of the selected phytoconstituents in A.
conyzoides leaves showed that 4 out of the 29 ligands (sitosterol, catechin, stigmasterol, and 5-benzamido-4-oxo-6-phenylhexanoic acid) interacted with and showed very good binding affinity toward the 3 crucial antifungal drug target receptors, and exhibited significant inhibition compared to the standard drugs.

Conclusion:

Therefore, sitosterol, catechin, stigmasterol, and 5-benzamido-4-oxo-6-phenylhexanoic acid from A.
conyzoides leaves hold a promising potential to be explored for their antifungal activities.

Published: December 2022

Background:

Streptococcus pyogenes is a significant pathogen that causes various types of human diseases which range from mild to fatal illness. This work was designed to assess the value of symptoms in the prediction of disease and macrolides resistance.

Methods:

We conducted a cross-sectional hospital-based study during 2020–2021 in Kosti Teaching Hospital (Kosti city, Sudan) to evaluate the link between symptoms with Group A Streptococcus (GAS) infection. Streptococcal tonsillitis was diagnosed by throat swabs culture, and macrolides resistance was detected by phenotypic and genotypic methods.

Results:

There was no significant variation in the mean of reported symptoms between gender and residence. Macrolides resistance and resistance genes had no significant effect on symptoms. On correlation analysis, age and education level were negatively correlated with symptoms score.

Conclusions:

The study highlights the link between symptoms with GAS tonsillitis and suggests the requirement for more care in children.

Published: December 2022

Background:

Vipera berus berus and Vipera berus
nikolskii are the most widely spread Old World vipers in Europe, who contribute to almost all cases of snakebites on this territory. Their venoms are known to cause proteolysis, thrombocytopenia, induction of neurotoxicity and haemorrhage, among which proteolytic action constitute to the possible affection of all metabolic pathways in the targeted organs and in the whole organism.

Methods:

The influence of the viper venoms on the adrenal glands and testicles of injected rats was studied through the analysis of the concentration of proteins (Bradford method), evaluation of the qualitative protein profile (disc electrophoresis), distribution of active proteolytic molecules in the studied tissues (enzyme electrophoresis) and estimation of the appearance of low molecular weight molecules.

Results:

The decline of the number of the total protein, the alterations of the protein composition and the enzymatic redistribution were declared to appear in these organs under the action of the studied venoms proving the assumption of the proteolysis activation. Whereas, the increase in the level of low molecular weight molecules has emerged showing the onset of the state of toxicity.

Conclusion:

the study of the influence of the V. berus berus and V. berus nikolskii venoms on the protein balance of adrenal glands and testicles was performed, showing the impact on the amount of total proteins, its redistribution and connection with toxicity and proving the onset of pathological process.

Authors: Atere Adedeji David , Chukwuemeka Cinderella Ebele , Popoola Olayiwola Akanji , Olawoye Temiloluwa Deborah
Published: December 2022

Background:

Gestational diabetes mellitus(GDM) is carbohydrate intolerance that causes hyperglycemia in pregnancy. It increases maternal and perinatal mortality. This study aims to determine the relationship between gestational diabetes and plasma iron and methemoglobin levels.

Methods:

The study included 40 GDM patients, 30 nongestational diabetes pregnant women (NGPW) attending the antenatal clinic of Federal Medical Centre, Owo, and 30 women with neither diabetes nor pregnancy (NDNP). Ten milliliters of venous blood was collected from each individual and dispensed into an appropriate bottle. Fasting blood sugar (FBS), serum level of iron (Fe2+), methemoglobin (MetHb) concentration, and packed cell volume (PCV) were determined using standard laboratory techniques. The data were properly analyzed statistically, and P < 0.05 was considered statistically significant.

Results:

The mean value of MetHb and Fe2+ was significantly higher among GDM and NGPW when compared with NDNP (P < 0.05) while the mean value of PCV was considerably lower (P < 0.05). Furthermore, there was a significant positive correlation between FBS and PCV in GDM, while FBS had a negative correlation with only Fe2+ in GDM.

Conclusion:

It was concluded that elevated serum iron levels and MetHb were found to be associated with the development of GDM in this study, and could thus be used as biomarkers for assessment.
Plasmid-mediated AmpC β-Lactamase Gene Analysis in Klebsiella Pneumoniae Clinical Isolates
Authors: Jomehzadeh Nabi , Ahmadi Khadijeh , Shaabaninejad Hasti , Eslami Gholamali
Published: December 2022

Background:

In Gram-negative bacteria, including Klebsiella
pneumoniae, the production of AmpC beta-lactamase enzymes is one of the main resistance mechanisms for beta-lactam antibiotics. This study aimed to investigate the phenotypic and molecular characteristics of AmpC beta-lactamases in K.
pneumoniae clinical isolates in Southwest Iran.

Methods:

This study was conducted on 55 K.
pneumoniae strains collected from various clinical samples. Identification of isolates was done using routine bacteriological and biochemical tests. After performing the antibiotic sensitivity test, the cefoxitin-resistant strains were analyzed using the phenotypic test in terms of the production of AmpC beta-lactamase enzymes. Finally, the frequency of plasmid-mediated AmpC genes was determined using a polymerase chain reaction test.

Results:

Out of the 55 isolates, 63.6% (n = 35) were obtained from urine, 9.1% (n = 5) from blood, 12.7% (n = 7) from wounds, and 14.6% (n = 8) from sputum. The highest resistance rate was observed against amoxicillin (98.2%), followed by cefotaxime (78.2%) and ceftriaxone (72.7%). According to the phenotypic tests, the prevalence of AmpC producers was 25.4%. Of all isolates, 36.3% (20/55) harbored different AmpC-associated genes, and bla
MOX, bla
CIT, bla
EBC, and bla
DHA genes were detected in 1, 2, 8, and 13 strains, respectively. None of the isolates harbored bla
ACC and bla
FOX genes.

Conclusion:

It is important to revise the prescription policy of effective antibiotics in this region, since a significant prevalence of AmpC beta-lactamase-producing isolates has made antibiotic resistance a serious concern.
The Prediction of Lung Cancer Prognosis with Blood Lipid Levels and Ratios at the Time of Diagnosis
Authors: Arslan Ferhat , Yalçin Selim , Karahan Irfan
Published: December 2022

Background:

Emerging evidence has linked lipid metabolism disorder with lung diseases, but the relationship between blood lipid profile and lung cancer risk is controversial and inconclusive. It was aimed to investigate the relationship of lipid levels and ratios at the time of diagnosis to the prognosis prediction of lung cancer.

Methods:

Sociodemographic and disease-related clinical characteristics of 92 patients diagnosed with lung cancer were reviewed retrospectively. Patients with available lipid parameters at the time of diagnosis were evaluated. Hemogram parameters of the patients included in the study, creatinine and estimated glomerular filtration rate, alanine aminotransferase level, albumin level, C-reactive protein level, as well as total cholesterol (TC)/high-density cholesterol (HDL) ratio, non-HDL/HDL ratio, low-density lipoprotein/HDL ratio, and triglyceride/HDL ratios were examined.

Results:

The mean age at presentation was 64.2 ± 9.1 years. The distribution of lung cancers is 6 (6.5%) for small cell lung cancer (SCLC) and 86 (93.5%) for non-SCLC. The median follow-up period of the patients is 12 months. During the follow-up, 63 (68.5%) of the patients died. In the univariate analysis, increased non-HDL/HDL ratio was related to mortality. In multivariate analysis, disease stage, albumin level, and TC level were found to be variables affecting the mortality.

Conclusion:

TC levels at the time of diagnosis can be a guide in determining the prognosis. More experimental studies are needed to elucidate the relationship between the lipid metabolism and lung cancer etiology and to determine the role of lipid levels and ratios in prognosis prediction.
Conundrum of Cranial Ewing’s Sarcoma: Facts to Consider
Authors: Bhardwaj Sheeba , Paul Diptajit , Kaushal Vivek
Published: December 2022

ABSTRACT

Peripheral primitive neuroectodermal tumor of cranium or primary cranial Ewing’s sarcoma (ES) is an isolated phenomenon. So far, <100 cases are documented. The literature revealed good outcomes in favor of cranial ES due to less chances of distant metastasis; however, standardized treatment strategy is yet to developed. Here, we depicted the aggressive course of cranial ES by reporting the same in an 18-year-old young boy having right-sided scalp swelling of the 10-month duration. Despite providing combined modalities of treatment, the young boy departed his life with a short time of 12 months after diagnosis. Our case revealed the importance of early diagnosis in cranial ES. Strong emphasis should be given to employ different therapeutic approaches at the right time. Combination chemotherapy should be started as early possible and adjuvant radiotherapy is always recommended in subtotal resection. More case studies in future will also guide about independent prognostic markers of cranial ES.
Intensive integrated yoga therapy on lipid profile, body composition, and insulin resistance among Type 2 diabetes mellitus
Authors: Bilagi Ashween , Kurian Jintu , Bilagi Shilpa
Published: December 2022

Background:

Insulin resistance (IR) is a leading cause of the onset of Type 2 diabetes mellitus (T2DM) among overweight and obese individuals irrespective of their age. This study aimed at assessing the impact of 2 weeks of intensive integrated yoga therapy (IIYT) among overweight individuals diagnosed with T2DM identified with higher IR.

Methodology:

The current single-group longitudinal pre–post study enrolled adults (n = 30) from a residential health-care center, Bengaluru (India), who were subjected to IIYT, comprising practices at physical, emotional, and intellectual levels incorporating āsana (postures), prānāyāma (breathing exercise), kriyā (internal cleansing technique), meditation, notional correction, counseling, yogic diet, and devotional sessions. Pre- and postoutcome measures were homeostatic model assessment for IR (HOMA-IR), fasting serum insulin, lipid profile, body composition, and anthropometric measurements.

Results:

A significant reduction in HOMA-IR (35.69%, p < 0.001), fasting insulin (28%, p < 0.001), fasting glucose (12.3%, p = 0.039), triglycerides (15.43%, p = 0.003), very low-density lipoprotein (15.5%, p = 0.003), body mass index (2.4%, p < 0.001), weight (2.3%, p < 0.001), hip circumference (1.01%, p < 0.001), waist circumference (1.4%, p < 0.001), and body fat percentage (1.8%, p = 0.039) and a significant increase in lean mass percentage (0.95%, p = 0.045) and water percentage (0.99%, p = 0.04) were observed among the subjects.

Conclusion:

Regular practice of IIYT regulates lipid and anthropometric measures and increases lean body mass, thereby managing IR, among overweight Type 2 diabetes. However, future works might confirm the findings of the present study.

Introduction:

Prisoners are vulnerable to mental health-related problems. The present study was conducted to determine the effect of 6 months Yoga practice on the mental health of jail inmates. The study's main objective was to assess the impact of 6 months of Yoga practice on the mental health of Jail inmates.

Materials and Methods:

A total of 37 Tihar Jail inmates (27 males and 10 females) participated in the study. With the help of questionnaires, anxiety, depression, stress, aggression, physical health, psychological health, and general well-being of the jail inmates were assessed. The study employed a Single Group Repeated Measures design. Pre and posttest methods were adopted in the study.

Results:

Significant reduction in stress and aggression and improvement in physical health, psychological health, and general well-being were found after 6 months Yoga-training; however, there was no significant reduction in anxiety and depression in the combined group. In male inmates, anxiety, depression, stress, and aggression were reduced significantly, and their physical health, psychological health, and general well-being significantly improved after 6 months of Yoga training. In female inmates, aggression got reduced after 6 months of regular Yoga practice; but no significant changes were found in other parameters.

Conclusion:

Regular Yoga practice for 6 months significantly improved the mental health of Tihar Jail inmates, especially male inmates. However, there is a need to conduct more studies to confirm the results.
Heavy metals determination and microbial assessment of some species of frozen fish sold at Utako Market, Abuja, Nigeria
Authors: Useh M.U. , Etuk-Udoh G. , Uzama D.
Published: December 2022

This work assessed heavy metals [Copper (Cu), Iron (Fe), Cadmium (Cd), Zinc (Zn) and Lead (Pb)] concentrations and microbial load in the tissue (skin, fillet and gills) of some frozen fishes [Clupea harengus (herring), Scomber scombrus (Mackerel), Urophycis tenuis (White hake)] sold in Utako market using Flame Atomic Absorption Spectrophotometer (AAS) and standard microbiological procedures. The results obtained revealed that the concentrations of all the heavy metals determined except Zinc (Zn) were above the Food and Agriculture Organization (FAO) and World Health Organization (WHO) permissible limits in fresh water fish and fishery products. The total aerobic plate count (APC) was between 2.15×103 cfu/g and 47.6×103 cfu/g, total coliform count ranged from 1.85 × 103 cfu/g to 2.03 × 103 cfu/g and fungal counts ranged between 6.02x102 cfu/g and 18.3x102 cfu/g. The microbiological study showed that the skin had more load compared to other studied tissues and in all, the microbial load except APC also exceeded the FAO/WHO acceptable limits for frozen fish products. This study indicated that the products were not ideal for consumption due to bioaccumulation of these heavy metals and the issue of post-harvest contaminants that can multiply in case of defrosting which may impact negatively on the consumers. It is recommended that there should be proper handling and examination of frozen foods and they should be properly cooked before consumption.

Postawa Francji i jej belgijskiej sojuszniczki wobec wojny polsko-bolszewickiej
Authors: Łaptos Józef

The Stance of France and Belgium Toward the Polish-Bolshevik War

The article is an attempt to underline the difference in the conduct of foreign policy by two allied countries. One of them – France, had the opinion of the most powerful state in Europe after World War I, and the other – Belgium, was a small country that decided to abandon its neutrality (imposed by the great powers in 1839). Such an alliance, salutary for strengthening the security guarantees towards the former occupant, brought with it fears of domination and instrumental treatment. In matters of eastern policy, both countries were concerned about the loss of numerous investments and capital investments in tsarist Russia. It was through this prism that the Polish-Bolshevik war was assessed. The second factor that distinguished the two countries in their approach to the war was the different composition of the government. While in France the electoral victory of the National Bloc facilitated the conduct of politics, the government of catholic-socialist coalition in Belgium faced serious obstacles from the socialists, which was manifested in the decision concerning the transit of weapons to Poland. French aid in the form of weapons supplies and support for Poland from the diplomatic side led to an alliance with Poland. Belgium took advantage of the end of the war to establish, above all, economic cooperation.

The Greek welfare state has faced multidimensional crises from the first period of its existence until now. From the traditional unstable democratic and institutional context to the financial crisis, which exacerbated social problems, and from the latter to the pandemic, which posed challenges for the immediate handling of the health needs as well as long term necessities for measures in order to address the economic shortcomings of the pandemic, the Greek welfare state has been in a permanent strain. This study aims to present the main historical as well as contemporary challenges of the Greek welfare state and to draw some conclusions about its role in the post-covid era as well as to emphasize the main directions in order to address old and new social problems, always with reference to relative empirical data.
Utopia of the New Town – Implemented or Degraded? Novi Beograd, Nowa Huta and Tirana e Re in a Socialist and Post-Socialist Perspective
Authors: Bogusławska Magdalena , Czekalski Tadeusz
Published: December 2022

The paper follows in the assumption that the transformations of central-European and Balkan cities taking place in the second half of the 20th century can be considered a symptom of complex economic, social and political processes related to the development and decline of the culture of socialism. Changes after the Second World War were closely interconnected with the urbanization project, which was implemented in two ways – either by rebuilding, reorganizing and resemantizing old cities, or by creating cities and urban communities – in a modernist spirit – from scratch. We consider these issues by comparing three examples of cities with different historical experience, which shaped their identities within culturally and politically different frames of reference.

The subject of thus oriented considerations is the question of what happened to the socialist utopia which at the end of the 20th century was put to the test. What was its fate depending on various politically – but also culturally-motivated scenarios of political transformation? In what way and by whom is its heritage appropriated in the 1990’s? While analyzing the fate of the utopia of the new city from a post-communist perspective, it should be noted that although individual projects did not meet the ideals and hopes of their designers, they proved to be an impulse that released social activityqualitatively different from existing traditional patterns and initiated a thorough redefinition of urban identities.

Authors: Hari Kumar Raveendran Pillai  , Mayadevi Nanappan  , Mini Valiyakulam Prabhakaran  , Shenil Pushpangadan Sathyabhama
Published: December 2022

Detection, diagnosis, and localization of switching faults in electric drives are extremely important for operating a large number of induction motors in parallel. This study aims to present the design and development of switching fault detection, diagnosis, and localization strategy for the induction motor drive system (IMDS) by using a novel diagnostic variable that is derived from discrete wavelet transform (DWT) coefficients. The distinctiveness of the proposed algorithm is that it can identify single/multiple switch open and short faults and locate the defective switches using a single mathematical computation. The proposed algorithm is tested by simulation in MATLAB/Simulink and experimentally validated using the LabVIEW hardware-in-the-loop platform. The results demonstrate the robustness and effectiveness of the proposed technique in identifying and locating faults.
A influência do preço das commodities para a formação da taxa de câmbio: um estudo empírico para países da América Latina
Authors: Corcelli Caique
Published: December 2022

Este trabalho se propõe verificar a hipótese de “commodity currency” para um conjunto de países da América Latina (Brasil, México, Chile, Uruguai e Colômbia). Segundo a literatura da área, países nos quais as exportações de commodities compreendem parte importante da pauta de exportação e do PIB teriam sua taxa de câmbio influenciada pela dinâmica desses preços no mercado internacional. Uma segunda hipótese de investigação é se o peso do setor no PIB de fato influencia a magnitude do efeito. Para tanto é utilizado um modelo de Mínimos Quadrados Generalizados para o período de 1998 a 2016. Os principais resultados deram razão a hipótese de "commodity currency", mas a segunda hipótese não se verificou. O grau de abertura da conta financeira e de capitais e principalmente a existência de um amplo mercado de câmbio futuro parecem ser a explicação mais provável das diferentes elasticidades preço da taxa de câmbio entre os países.
DA HIPÓTESE DE MERCADOS EFICIENTES ÀS FINANÇAS COMPORTAMENTAIS
Authors: Varella Angelo Cruz do Nascimento , Santos Roberta Teodoro
Published: December 2022

Um dos principais objetos de discussão em Finanças pauta-se na validade das premissas adotadas pela teoria clássica, amplamente estabelecida na década de 1970, destacando-se a racionalidade dos agentes econômicos. Na década seguinte, dada a crescente quantidade de evidências empíricas demonstrando um excesso de volatilidade no modelo dominante, surgem explicações comportamentais e axiomas psicológicos antes desconsiderados. Estas novas linhas de pensamento culminam na origem do promissor campo de estudos denominado de Finanças Comportamentais. O objetivo deste trabalho é analisar a complexa evolução desse segmento acadêmico que atualmente configura uma relevante vertente dentro da área de Finanças. Trata-se de um estudo qualitativo, no qual utiliza-se a técnica de revisão narrativa como metodologia. Os resultados evidenciam a evolução e consolidação da Psicologia e das teorias comportamentais no universo das Finanças, equiparando essa vertente às linhas clássicas de pensamento, que também permanecem em destaque na literatura, em função de suas relevantes modelagens matemáticas.
Cultivating Capital: Sustaining the STEM Identities of Rural Latinx Youth
Authors:   North Carolina State University, De La Torre Corina , Dobis Corrie
Published: December 2022

This paper seeks to explore how rural Latinx students’ STEM identity development can be fostered by utilizing their cultural capital. Using both a community cultural wealth and science identity model, this paper reviews previous literature to conceptualize how and why rural Latinx youth are continuously underrepresented within STEM education and future career pathways. When forming STEM identities and aspirations for the future, Latinx students draw from six forms of capital- aspirational, linguistic, familial, social, navigational, and resistant. Throughout this paper, we discuss each of these six forms of capital wealth and the value rural Latinx students can bring into STEM educational spaces. Supporting rural Latinx students’ STEM identity development is a vital key to the disruption of systemic inequalities that perpetuate societal and institutional spaces. Conclusions drawn from the literature showcase how cultural wealth sustains the development of Latinx students’ STEM identities. Future considerations need to focus on the STEM disparities that still exist for this population of students, but specifically those in rural communities.

Zollinger-Ellison Syndrome is a rare disease caused by tumors called "Gastrinomas", causing high levels of gastrin that produces acid hypersecretion and even gastric ulcers. We present a 20-year-old patient with a 2-month history of pain in the epigastrium accompanied by nausea, vomiting, and weight loss with a history of upper gastrointestinal bleeding from a duodenal ulcer, which on physical examination revealed a tumor in the epigastrium. Contrast-enhanced abdominal CT showed a tumor mass in the tail of the pancreas. She underwent surgery, performing a corporocaudal pancreatectomy and splenectomy, with favorable post-surgical evolution. The anatomopathological study reports pancreatic gastrinoma.

Girl-child is a biological female offspring from birth to eighteen (18) years of (Offorma, 2009). Girls’ education is also about ensuring that girls learn and feel safe while in school; complete all levels of education with the skills to effectively compete in the labor market; learn the socio-emotional and life skills necessary to navigate and adapt to a changing world; make decisions about their own lives and contribute to their communities and the world (Tembon & Fort, 2008). Community radio is a radio of the people by the people and for the people which need to broadcast developmental programs. Community radio should be able to broadcast educational related programs like youth speak up, especially with respect to Girl-child education. This will help change the perception of the local people about educating the girl-child. It is within this perspective that, community radio can be used as a tool towards enhancing Girl-child education towards an ameliorated national development within Kumbungu District using the Mixed Method Approach (Quantitative and Qualitative methods), and informants’ interviews and; Semi-structured questionnaires for household interviews to assess how community-based radio can be used to bring about effective Girl-Child education. The study also used both secondary and primary data with the help of self-administered questionnaire. 150 respondents were interviewed within 5 communities in the study area using both simple random and purposive sampling. It was realized that, there was least participation of members in programing within the study area. It was also found that factors such as age, marital status, and community radio influence, perception of Girl-Child education and program influenced were independent variables that influenced effective radio programs listening towards Girl-Child education.

Protection of employees against sexual harassment: The development, successes and shortcomings of the South African legal system
Authors: Calitz Karin
Published: December 2022

Despite extensive protection for employees against sexual harassment in the workplace, South African workplaces are still riddled with this harmful conduct. The severe consequences for victims and workplaces necessitate an analysis of the development of South African law to establish its successes, but also the shortcomings that continue to exist. Although there is a matrix of laws protecting employees against sexual harassment, the Employment Equity Act 55 of 1998, which regards harassment as a form of discrimination, is still the primary statute. In this article I argue that the tendency to focus on sexual harassment as a dignity and equality issue does not take sufficient cognisance of sexual harassment as a multifaceted issue involving criminal conduct, which threatens employees’ employment security and impacts on employees’ health and safety. An analysis of case law indicates that many employers have not adopted a policy on sexual harassment, and that some employers and the Commission for Conciliation, Mediation and Arbitration commissioners do not deal with sexual harassment in a gender-sensitive way, which is an approach endorsed by the International Labour Organization’s Violence and Harassment Convention 190 of 2019. This Convention emphasises the need for an inclusive, integrated approach to combat harassment. To align the protection of victims of harassment with the Convention, South Africa adopted a Code of Good Practice on the Prevention and Elimination of Harassment in the Workplace in 2022. This Code, dealing with different kinds of harassment, including sexual harassment, replaced the 2005 Code of Good Practice on the Handling of Sexual Harassment Cases in the Workplace. By comparing the 2005 Code and related jurisprudence to the 2022 Code, the article considers whether sexual harassment is likely to be addressed more effectively under the 2022 Code. The 2022 Code has made certain improvements to the 2005 Code, but the altered definition of sexual harassment indicates the difficulties created by adopting one code to cover both misconduct and discrimination. In addition, aspects of the Convention, such as protecting the health and safety of employees, are not dealt with effectively in the 2022 Code. A separate code should be issued in terms of the Occupational Health and Safety Act to address the psychosocial safety of employees and the compensation of victims in terms of the Compensation for Injuries and Diseases Act 130 of 1993.

Understanding the challenges and nature of land administration in the Tamale Metropolis, Northern Region, Ghana
Authors: Amakye Kingsford Gyasi , Ameyibor Mawusi Y.
Published: December 2022

Land plays an integral role in almost every economic activity. Land administration, therefore, is critical for the national development of a country. It is the hope and aspiration of many to own landed property for various reasons such as for residential, agricultural, and commercial purposes amongst others. Some African countries over the years have embarked on several land administration and land registration reforms to stimulate growth and reduce poverty amongst its people and these programmes are yielding positive results in some of these countries. This paper used semi-structured questionnaires to elicit information from fifty-one (51) participants in the Tamale Metropolitan Assembly, including traditional leaders, members of the general public who have ever registered their lands with the Lands Commission and Divisional heads at the Lands Commission, through randomly and purposefully selected sampling, respectively. This paper reveals that there are still teething challenges affecting land administration in Tamale which include the cost of land, cost of registration, corruption, weak coordination among land sector agencies, encroachment of state land, poor record-keeping on the land transaction and unidentified traditional land boundaries. This paper recommends effective coordination among land sector stakeholders including the land commission, land use and spatial planning authority and the traditional authorities for meaningful reforms on land administration.

This study was conducted in the savannah agroecological zone of Ghana to assess the different sheep management systems and identify potential stressors that compromise sheep productivity under these systems. A questionnaire and on-farm observations were used to obtain data from 176 farms on management system types, resources, husbandry practices and productivity. Four management systems were identified in the study area, namely extensive (41.5%), semi-intensive (38.1%), intensive (6.3%) and tethering (14.2%). Feeding systems used were free grazing/scavenging (24.43%), herded grazing (17.05%), zero-grazing/intensive feeding (6.25%), grazing plus supplementation (38.07%) and restricted grazing in the rainy season (14.2%). Most (87%) farmers under the extensive system did not house their sheep at all, but 88.1% of farmers using the semi-intensive system housed their sheep year round. Floor spacing per sheep was 1.06, 2.31, 2.17 and 1.47 sheep/m2 for the intensive, semi-intensive, extensive, and tethering, respectively. Preweaning mortality was significantly higher (40%) than post-weaning to yearling (34.9%) and adult mortality rates (14.3%) (ꭓ2 = 292, P <0.001). The extensive system has the highest (32.8%) mortality rate and the intensive system the least (14.9%) (ꭓ2 = 151, P <0.001). Reproductive indices (lambing percentage, age at first lambing, lambing intervals, and abortion rates) were all significantly influenced by the management system, with sheep managed under the semi-intensive and intensive systems performing better than sheep managed under the extensive system and tethering. Extensive management and tethering of sheep may expose Djallonké sheep to disease stress, chronic undernutrition, heat stress and walking stress compared to sheep under more intensive systems.

Purpose: This paper presents a brief overview which is linked to the bank network and its role in IT. It is also about the study of the role of the Government which has also played a proactive role in this by formulating policies and providing infrastructure, there are some advantages and disadvantages too, which need to be examined, and challenges faced by banking sectors and a few key positive and negative opinions on basis of SWOT analysis.
Methodology: The data has been collected from a variety of sources, including newspapers, research papers, websites, and journals. The information has been analyzed and synthesized to provide a comprehensive overview of the topic.
Findings: This research aims to provide a comprehensive overview of the extant research on the impact of information technology (IT) on banking. The findings suggest that IT has had a positive impact on banking in terms of efficiency, profitability, and customer service. However, the findings also reveal that IT has harmed employment in the banking sector. The banking sector in India is passing through tectonic changes with the onslaught of digital technologies. Traditional banks, which were dependent on human interaction and paperwork, are today struggling to keep pace with the new-age disruptors such as mobile payments, peer-to-peer lending, etc. They can now easily switch between banks depending on their needs and requirements. At the same time, banks are also looking to partner with FinTech to gain a competitive edge.
Originality: A robust banking system makes the lives of the average individual easier, its real impact is felt in the smooth functioning of businesses. The smooth flow of credit and mobilizing of savings are the hallmarks of an economy with an effective banking system.
Research Type: Descriptive Study.

Background and aims: Prescription drug monitoring programs (PDMPs) were implemented to decrease dangerous opioid prescribing but have had variable results. This report details how automatic PDMP review changed opioid prescribing across a statewide medical system.Design: An observational study.Setting: Fourteen hospital networks in the United States.Cases: Healthcare encountered from July 1, 2016 to June 30, 2019.Intervention: Starting from July 1, 2018, the patient’s PDMP data would be displayed automatically to providers in the unified electronic medical record (EMR) whenever the provider began to write for an opioid prescription.Measurements: Outcomes were prescriptions per encounter (PPE) and the morphine milligram equivalents (MME) per prescription. Outcomes were stratified by practice location, medication prescribed, and diagnosis. All data, including whether the prompt was triggered for a given encounter and whether a prescription was given, were extracted from the EMR. An interrupted time-series analysis was used to determine how PPE and MME changed in response to the implementation of automatic PDMP review.Findings: Of the 624,488 encounters examined, 18.37 percent (n = 114,710) were in emergency departments, 56.79 percent were admissions (n = 354,634), and 24.84 percent (n = 155,144) were outpatient visits. Opioid prescriptions were started and then canceled 24 percent of the time after the PDMP was shown. There was a decline in MME (βOverall + Policy Trends = –3.17, p = <0.0001), which was driven by inpatient (βOverall + Policy Trends = –2.10, p < 0.0001) and outpatient providers (βOverall + Policy Trends = –3.24, p < 0.01). A decline in MME was seen in all medication categories (–1.72 < βOverall + Policy Trends < –5.87, p < 0.01). There were no changes in these trends after excluding encounters for severe and acute pain.Conclusions: Automated PDMP review is associated with fewer prescriptions and smaller doses without decreasing appropriate use.
