Examining the Relationship Between the Gasoline A Market and the Prices of Hydrous Ethanol and Sugar to the Producer in Brazil
Authors: Lima Eduarda Ferreira Pacheco de Andrade , Melo André de Souza 
Published: October 2024

Objective: The aim of this article is to discuss the relationship between the gasoline A, sugar and alcohol markets in Brazil from May 2003 to February 2018.

Theoretical Framework: The sugarcane-alcohol sector has been affected by various policies, such as the Proálcool program, the intervention in ethanol blending in gasoline, and more recently, RENOVABIO. Thus, the market structure, in which gasoline and the sugarcane-alcohol sector are embedded, has shown a strengthening in the correlation of commodity prices, as highlighted in the literature.

Materials and Methods: Prices of gasoline A, hydrous ethanol and producer sugar were used to estimate an autoregressive vector model (VAR). Dummies were included in the system to determine the following events: the crisis of 2008, the interventionist policy of restraining gasoline prices in Brazil (between April 2011 and June 2014) and the time when flex-fuel vehicles became the largest part of the car fleet in the country (from 2012).
Results: The results suggested that there are links between the gasoline market and the sugar and alcohol sector, mainly with hydrous ethanol, which is a substitute for fossil fuel in consumption.

Research Implications: Therefore, it is crucial that the federal government consider the consequences that gasoline price controls can generate in the sugar and ethanol industry, so that producers do not suffer from greater business risks, as it has been in recent years.

Value: The literature extensively explores the price relationship between sugar and ethanol with gasoline C (common gasoline). This article innovates by observing in greater depth the price of gasoline A and its dynamics with the sugarcane-alcohol sector.

Frequency of t(11;22)(q24;q12) in Ewing’s Sarcoma using Fluorescence in Situ Hybridisation Technique
Authors: Gadhia P. K. , Vaniawala Salil 
Published: October 2024

Objectives:
Ewing’s sarcoma (ES) is a rare and aggressive cancer that primarily affects bone and adjacent soft tissues. It is characterised by the presence of the chromosomal translocation t(11;22)(q24;q12) in approximately 85–90% of cases. This translocation leads to the fusion of the EWSR1 gene on chromosome 22 with the FLI1 gene on chromosome 11, resulting in the production of the EWSR1-FLI1 fusion protein, which is crucial for oncogenesis. This research aims to investigate EWSR1 gene translocation using fluorescence in situ hybridisation (FISH).

Materials and Methods:
The study evaluated the prevalence of EWSR1 rearrangements using FISH. We analysed 39 tumour samples with the EWSR1 Dual Color Break Apart Probe Kit.

Results:
The study included 39 suspected cases of ES, comprising 21 males (53.8%) and 18 females (46.2%), with a median age of 17 years. Out of these, 11 males and eight females tested positive for ES.

Conclusion:
The study highlights the importance of FISH as a diagnostic tool for ES and its potential in differentiating ES from other small round-cell tumours.

Published: October 2024

Background and Objective
The continuum of care (CoC) is an important approach that should be prioritized for improving maternal health. The World Health Organization recommends working with individuals, families, and communities to ensure continuous care throughout pregnancy, childbirth, and the postpartum period. The purpose of this study was to assess the impact of an intervention on the awareness of the CoC among main caregivers and the completion of CoC among pregnant women.

Methods
During the COVID-19 pandemic, a community-based quasi-experimental study was conducted in two townships of the Yangon Region, including 200 pairs of pregnant women and their caregivers. The intervention focused on providing health education sessions and distributing pamphlets to caregivers in the intervention group. The study aimed to assess the awareness of main caregivers about CoC and completion of CoC among pregnant women. A key predictor variable for evaluating the outcome was receiving an intervention package by the main caregivers in the intervention. The analysis used logistic regression, including the propensity score model, and was conducted using STATA vs 15.1.

Results
The final analysis included 193 pairs. Most main caregivers were husbands: 47 were husbands in the intervention and 59 in the control group, while 24 mothers were included in both groups. The awareness of CoC for maternal health among main caregivers from the intervention group was 9.97 times higher than those from the control group (AOR = 9.97, 95% CI: 5.12 to 19.43, p < 0.001). The completion of CoC among women from the intervention group was 2.17 times higher than those from the controls (AOR = 2.17, 95% CI 1.08 to 4.37, p < 0.05). The awareness of main caregivers was found to be a significant predictor for completion of CoC.

Conclusion and Global Health Implications
Health education intervention for main caregivers could improve CoC completion among pregnant women. It provided baseline information for further interventions at the family level for improving CoC among pregnant women in the future.

Authors: Singh Yogindher , Rajamohanan Remya Raj , Vasudevan Senthilvel , Kuruvila Sheela 
Published: October 2024

Objectives:
The objective of this study was to determine the effectiveness of intralesional injection of bleomycin in the management of difficult-to-treat and resistant cutaneous warts.

Material and Methods:
A total of 54 patients were enrolled in the study, of whom 52 completed it. We administered 0.1% bleomycin over the warts and conducted follow-up at 4, 8, and 12 weeks. If the warts were not completely clear, we administered the next dose of intralesional bleomycin at each visit until the third visit. If the lesions resolved at the third visit, we conducted a telephonic interview for the next follow-up at the end of 12 weeks to record any recurrence of warts and residual side effects.

Results:
Out of 54 patients enrolled in the study, two were lost to follow-up. About 49 (94.2%) patients had clearance of warts at the end of the study period. About 45 (86.5%) patients had complete resolution of lesions after the first session. Three patients achieved complete clearance after the second treatment session. One patient achieved complete clearance at the end of the 12th week. One patient showed a partial response at the end of the 12-week treatment. There was no response for two patients at the end of 12 weeks. Two patients were lost to follow-up.

Conclusion:
The present study demonstrates that intralesional bleomycin is an efficient and safe treatment option in the management of resistant and difficult-to-treat warts.

MODIFIED ALGORITHM OF PARTICLE SWARM OPTIMIZATION, FOCUSED ON THE TASK OF MONITORING BY A GROUP OF ROBOTS
Authors: Кан Л. , Карпенко А.П. 
Published: October 2024

В работе предложен новый алгоритм глобальной оптимизации PSO+, который представляет собой модификацию канонического алгоритма роя частиц PSO. Модификация направлена на обеспечение возможности использования алгоритма PSO+ для решения задач групповой робототехники, сводящихся к локализации глобального экстремума некоторой скалярной целевой функции. Модификация заключается в ограничении скорости частиц популяции и, главное, в замене концепции близости частиц: вместо близости в топологическом пространстве, используемом алгоритмом PSO, алгоритм PSO+ построен на основе близости частиц в пространстве поиска.
The paper proposes a new algorithm named PSO+ for global optimization, which is a modification of the canonical algorithm PSO for the swarm of particles. The modification is aimed at ensuring the possibility of using the algorithm PSO+ for solving problems of group robotics, which boil down to localizing the global extreme of a certain scalar objective function. The modification consists in limiting the particle velocity and, most importantly, in replacing the concept of particle proximity: instead of proximity in the topological space used by the algorithm PSO, the algorithm PSO+ is based on the proximity of particles in the search space.

Background : Acute appendicitis is the most common cause of surgical acute abdomen. Perforation of appendicitis is associated with increase risk of postoperative complications and mortality. Routine peritoneal drainage after appendectomy for perforated appendicitis remains a topic of debate. Objectives: To evaluate the benefit of abdominal drainage post open appendectomy for perforated appendicitis and to study the impact of abdominal drainage on post-operative complications and on length of hospital stay. Methods: A cross-sectional, observational, prospective study was conducted among 85 Patients with perforated appendicitis who underwent open appendectomy Al-Thawra Modern General Hospital and Al-Kuwait University Hospital in Sana'a city from March 2022 to March 2023..Data was analyzed using the statistic package SPSS 23. Results: 85 patients were classified into two groups based on intra-operative insertion of abdominal drainage. There were 50 patients in the drain group compared to 35 patients in the no-drain group. In both groups, majority of patients were male. Most of patients in both groups were in the age group (11-25 years). The main complain of patients was pain, which started around umbilicus, then shifted to right iliac fossa. All patients in both group had tenderness in right iliac fossa. Fever and rebound tenderness were prominent signs in both groups. Leukocytosis was present in 68 % of patients in the drain group compared to 80% in the no drain group. Most of patients in both groups had longer duration of symptoms for three days and more. The tip of appendix was the most common site of perforation in both groups. Surgical site infection occurred in 5 patients (10%) in the drain group compared to 2 patients (5.7%) in the no-drain group. Intra-abdominal abscess occurred in one patient in each the drain group and the no-drain group. Postoperative ileus occurred in one patient in the drain group compared to no patients in the no-drain group.
Detection of airborne wild waterbird-derived DNA demonstrates potential for transmission of avian influenza virus via air inlets into poultry houses, the Netherlands, 2021 to 2022
Authors: Bossers Alex , de Rooij Myrna MT , van Schothorst Isabella , Velkers Francisca C , Smit Lidwien AM 
Published: October 2024

Background
Outbreaks of highly pathogenic avian influenza (HPAI) on poultry farms and in wild birds worldwide persists despite intensified control measures. It causes unprecedented mortality in bird populations and is increasingly affecting mammalian species. Better understanding of HPAI introduction pathways into farms are needed for targeted disease prevention and control. The relevance of airborne transmission has been suggested but research involving air sampling is limited and unequivocal evidence on transmission routes is lacking.

Aim
We aimed to investigate whether HPAI virus from wild birds can enter poultry houses through air inlets by characterising host materials through eukaryote DNA sequencing.

Methods
We collected particulate matter samples in and around three HPAI-affected poultry farms which were cleared and decontaminated before sampling. Indoor measurements (n = 61) were taken directly in the airflow entering through air inlets, while outdoor air samples (n = 60) were collected around the poultry house. Positive controls were obtained from a bird rehabilitation shelter. We performed metabarcoding on environmental DNA by deep sequencing 18S rRNA gene amplicons.

Results
We detected waterbird DNA in air inside all three, and outside of two, poultry farms. Sequences annotated at species level included swans and tufted ducks. Waterbird DNA was present in all indoor and outdoor air samples from the bird shelter.

Conclusion
Airborne matter derived from contaminated wild birds can potentially introduce HPAI virus to poultry houses through air inlets. The eDNA metabarcoding could assess breaches in biosecurity for HPAI virus and other pathogens potentially transmitted through air via detection of their hosts.
