Abstract
Background
Linea alba hernias are relatively rare types of hernias. They manifest as small protrusions situated in the linea alba between the umbilicus and xiphoid cartilage. Usually, hernia contents comprise the pre-peritoneal fat, omentum, and gastrointestinal tract. However, very few cases of linea alba hernias involving the hepatic round ligament have been reported, to date.

Case presentation
An 80-year-old woman presented with upper abdominal pain and a 1-week history of a mass in the upper midline. Abdominal computed tomography revealed adipose tissue protruding from the abdominal wall contiguous with the hepatic round ligament, suggesting a linea alba hernia. During surgery, the hernial sac content was found to be a mass, which was resected. A linea alba hernia defect measuring 20 mm was repaired using a mesh. Histopathological findings revealed that the mass included mature adipocyte proliferation with broad fibrous septa, which was diagnosed as fibrolipoma of the hepatic round ligament.

Conclusions
We report the first case of a linea alba hernia involving fibrolipoma of the hepatic round ligament worldwide and describe the clinical features, diagnosis, and surgical procedure with a literature review.

Published: May 2023

Abstract
Background
Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. It is generally diagnosed and surgically repaired early in life, with good overall outcomes.

Case presentation
We report the case of a patient incidentally diagnosed with paucisymptomatic TOF at the age of 56 years old, during investigations for carbon monoxide poisoning. The patient had a history of thyroidectomy, arterial hypertension, and four uncomplicated vaginal deliveries.

Conclusions
This case shows us that some patients with TOF can reach older ages without surgical correction. Late surgical repair should be meticulously decided on a case basis.

Abstract
Background
The incidence of typhoid fever is increasing in Egypt. The Widal test is the evaluation most widely used in Egypt for diagnosis, but it has many drawbacks; therefore, new diagnostic tools are needed. Our aim was to evaluate the diagnostic accuracy of the onsite typhoid IgG/IgM combo rapid test in diagnosing typhoid fever.

Method
Blood specimens were collected from 90 patients (of all ages) who presented with fever of more than 4 days’ duration. The OnSite Combo test and the Widal test were performed for all patients.

Results
The OnSite Combo test results were positive in approximately 24% of all patients; the Widal test results were positive in 18.9%; and typhoid was diagnosed through blood culture in 32.2%. The OnSite Combo test had 72.4% sensitivity, 98.4% specificity, a positive predictive value of 95.5%, and a negative predictive value of 88.2%. In contrast, the Widal test had 51.7% sensitivity, 69.7% specificity, a positive predictive value of 88.2%, and a negative predictive value of 80.8%.

Conclusions
The onsite combo test was more efficacious than the Widal test in diagnosing typhoid fever.

Abstract

Context
There is no early, first-trimester risk estimation available to predict later (gestational week 24-28) gestational diabetes mellitus (GDM); however, it would be beneficial to start an early treatment to prevent the development of complications.

Objective
We aimed to identify early, first-trimester prediction markers for GDM.

Methods
The present case–control study is based on the study cohort of a Hungarian biobank containing biological samples and follow-up data from 2545 pregnant women. Oxidative–nitrative stress-related parameters, steroid hormone, and metabolite levels were measured in the serum/plasma samples collected at the end of the first trimester from 55 randomly selected control and 55 women who developed GDM later.

Results
Pregnant women who developed GDM later during the pregnancy were older and had higher body mass index. The following parameters showed higher concentration in their serum/plasma samples: fructosamine, total antioxidant capacity, testosterone, cortisone, 21-deoxycortisol; soluble urokinase plasminogen activator receptor, dehydroepiandrosterone sulfate, dihydrotestosterone, cortisol, and 11-deoxycorticosterone levels were lower. Analyzing these variables using a forward stepwise multivariate logistic regression model, we established a GDM prediction model with a specificity of 96.6% and sensitivity of 97.5% (included variables: fructosamine, cortisol, cortisone, 11-deoxycorticosterone, SuPAR).

Conclusion
Based on these measurements, we accurately predict the development of later-onset GDM (24th-28th weeks of pregnancy). Early risk estimation provides the opportunity for targeted prevention and the timely treatment of GDM. Prevention and slowing the progression of GDM result in a lower lifelong metabolic risk for both mother and offspring.
Recasting the Villain in the Communitarian American Dream: Obama in Osawatomie and the 2012 Election
Authors: Rowland Robert C. 
Published: May 2023

Abstract
President Barack Obama faced very difficult electoral prospects in the summer of 2011. A slow economic recovery, along with Republican efforts to block his agenda, had undercut his message of hope and change. Obama's speech in Osawatomie, Kansas has been widely recognized as a crucial moment in his successful 2012 campaign. Obama's speech was important not because he supported new policies but because it corrected a major flaw in the community-oriented narrative at the core of his message. Obama reenergized his retelling of the American Dream by shifting the villain in his narrative from partisanship to the greedy rich.

Authors: Roifman Chaim M. , Vong Linda 
Published: May 2023

Severe combined immunodeficiency (SCID) is caused by critical genetic defects affecting the immune system. Early diagnosis and intervention are essential for preventing life-threatening infections, end-organ damage, and complications. Newborn screening for SCID is currently performed in many provinces and territories across Canada. The SickKids Newborn Screening Centre in Toronto, Ontario, is a quaternary referral centre that has evaluated SCID newborn screen-positive infants since the program’s introduction in 2013. Here, we provide updated algorithms for clinical investigation and follow-up of infants with an initial positive screen. Statement of novelty: We provide algorithms for the clinical follow-up of SCID newborn screen-positive infants at a quaternary referral centre.
Why do certain cancer cells alter functionality and fuse?
Authors: Dittmar Thomas , Sieler Mareike , Hass Ralf 
Published: May 2023

Abstract
Cancer cell fusion represents a rare event. However, the surviving cancer hybrid cells after a post-hybrid selection process (PHSP) can overgrow other cancer cells by exhibiting a proliferation advantage and/or expression of cancer stem-like properties. Addition of new tumor properties during hetero-fusion of cancer cells e.g. with mesenchymal stroma-/stem-like cells (MSC) contribute to enhanced tumor plasticity via acquisition of new/altered functionalities. This provides new avenues for tumor development and metastatic behavior. Consequently, the present review article will also address the question as to whether cancer cell fusion represents a general and possibly evolutionary-conserved program or rather a random process?
Pricing weather derivatives in an uncertain environment
Authors: Ali Zulfiqar , Hussain Javed , Bano Zarqa 
Published: May 2023

Abstract
This article deals with the problem of finding a pricing formula for weather derivatives based on temperature dynamics through an uncertain differential equation. Weather-related derivatives are being employed more frequently in alternative risk portfolios with multiple asset classes. We first propose an uncertain process that uses data from the past to describe how the temperature has changed. Despite this, pricing these assets is difficult since it necessitates an incomplete market framework. The volatility is described by a truncated Fourier series, and we provide a novel technique for calculating this constant using Monte Carlo simulations. With this approach, the risk is assumed to have a fixed market price.

Authors: Wangdi Mani 
Published: May 2023

This study investigated the effectiveness of video clips in enhancing the learning achievement of eighth-grade students in mathematics at Sonamthang Lower Secondary School. An experimental method using a pre-test and post-test was employed as the research design. The experimental group comprised 28 eighth-grade students. Data were analysed in two parts: test score analysis and students’ opinion analysis. Paired sample t-test and descriptive statistics were computed using Google Sheets Add-on XLMiner Analysis ToolPak to determine the differences in the pre-test and post-test scores. The results revealed that the pre-test mean was statistically insignificant, while the post-test mean showed a significant difference between the experimental and control group. Therefore, the study concludes that the use of video clips enhances students’ test scores and also increases their ability to solve higher-order thinking questions. Further, students’ opinion analysis indicated a preference for learning mathematics using video clips. As such, it was recommended that teachers use video clips as an instructional tool to enhance students’ academic achievement and foster motivation.

To study the statistics of the epidemiology, co-morbidities, clinical presentations, management and prognosis of the study group. This is a retrospective study conducted in a tertiary care hospital in South India, among 100 subjects, between May 2021 and August 2021 when the Mucor mycosis cases were frequently being diagnosed and treated amongst COVID-19 infected patients. The results showed that 34.0% were between 51-60 years with 100% patients confirmed COVID positive through RTPCR tests. 86.0% had confirmed mucor on CT scan. 50.0% had both eyes vision of 6/60 on presentation. 67.% had periorbital swelling with 51% having prior co-morbidities.63.0% patients received tablet Posaconazole 30mg as medical treatment and 60.0% required no surgical management.10.0% required orbital exenteration and 21.0% required partial maxillectomy.2% experienced orbital apex syndrome as associated complications.97.0% were discharged post treatment with 3% mortality. There was a positive correlation of medical management with respect to anterior segment and posterior segment findings P&#60;0.001 and P=0.79. There was a positive correlation between surgical treatment and anterior and posterior segment findings P&#60;0.001 and P=0.43. There was a positive correlation between co-morbidities and death P&#60;0.001, with 32.0% uncontrolled diabetics. This study shows that immune suppression is directly related to infectivity by mucor mycosis. In order to contain symptomatology and grave prognosis amongst patients, early diagnosis, affordable treatment and follow-up including patient education about the etiology and pathogenesis of the disease must be available.

Published: May 2023

Background: Millions of people's lives, as well as their physical and mental health, were put in jeopardy when COVID-19 emerged. The pandemic resulted in a high death rate. Health protocols prevented the bereaved from attending the funeral. As a result, many people faced unfinished mourning. This study was conducted with the aim of identifying the meaning of mourning and the strategies used by bereaved spouses
Methods: The research method was qualitative and based on descriptive phenomenological strategy. Among the bereaved people who met the criteria to enter the research, 15 people were selected using the purposeful sampling method and using semi-structured interviews until saturation was reached. The data were coded using the Colaizi method and finally the results were analyzed using the Max Quda software.
Results: After extracting the research findings in the form of 460 concepts, 27subcategories, and 9 main categories, they were represented as an educational package. Major themes were the obligation to hold mourning, social feedback from others, gradual healing, the experience of widowhood, existential emptiness, psychological collapse, the progressive repercussions of widowhood, and comprehensive self-talk about complicated pathological effects of death and mourning
Conclusion: Considering Coronavirus disease (COVID-19) and the lack of mourning for the loss of a spouse, health care practitioners must address these women's psychological and social needs. Thus, knowing these problems can assist health care workers and bereaved women's families in minimizing the psychological challenges of acute sorrow.

Authors: Haradanhalli Ravish , Kumari Nitu , Mandya Ramya , Surendran Jithin 
Published: May 2023

Background: World Health Organization (WHO) estimates that seeking prompt and appropriate healthcare could reduce child deaths by nearly 30%. In this background, the present study was conducted to 1. assess the health services utilization for diarrhoea and ARI (acute respiratory infections) among under-5 children in South Bengaluru, 2. determine the factors influencing mothers for utilization of health services.
Methods: Authors conducted a cross-sectional study in 10 randomly selected wards of South Bengaluru from July, 2019 to January, 2020 using multistage sampling. 432 mothers with under-5 children were interviewed regarding morbidities of their children in the previous one month and the health services they utilised, using a semi-structured questionnaire derived from multiple indicator cluster survey (MICS) by UNICEF. Data were analysed using SPSS 21.0 for descriptive statistics and logistic regression.
Results: 95 of the participants had illnesses in the past one month; but, only 41 had used health facilities for treatment, mainly in the private sector (68.3%). The reasons for non-utilization of healthcare services were negligence (36.9%), long waiting time at the center (22.4%), financial constraints (20.4%) and mothers’ jobs (9.6%). The most significant factors influencing the health services utilisation were: literacy status of the mother (predisposing factor), low socio-economic status/ BPL (below poverty line) families (enabling factor), and severity of symptoms (need factor).
Conclusion: Utilisation of healthcare services for under-five morbidities in the studied population was inadequate. The influencing factors have to be addressed on a priority basis to fulfil the goal of universal health coverage.
