Authors:   Instytut Nafty i Gazu – Państwowy Instytut Badawczy, Turkiewicz Anna , Janiga Marek ,   Instytut Nafty i Gazu – Państwowy Instytut Badawczy
Published: September 2023

This paper refers to several aspects of research studies supporting the oil and gas industry – in particular underground gas storage (UGS) in depleted deposits and salt caverns – and focuses on questions related to the formation of hydrogen sulphide contamination in reservoir conditions as well as on methods for limiting unfavourable biogenic phenomena. The main problem found at gas storage facilities is the activity of sulphate reducing bacteria (SRB). The elimination or limitation of H2S generation in microbiologically contaminated environments have been the subject of many extensive studies. Biocides, biocorrosion inhibitors and H2S scavengers are widely applied to protect reservoir structure, gas storage infrastructure as well as water-based drilling fluids from the negative effects of bacterial activity. One of the most popular biocidal products, recommended for oil and gas industry are triazine derivatives, laboratory tested in the presented biomonitoring studies. Triazine products prove very effective in biomass reduction and elimination of anaerobic bacteria, especially SRB. Before any industrial operation (based on technology of using biocides), it was necessary to analyse the sulphur compounds in the stored natural gas in different exploitation gas wells of UGS. It was also necessary to investigate the selection of a specific biocidal product and its proper concentration. A concentration that is too low may even stimulate the microbial growth; since the substance is not toxic for microorganisms, they may start to metabolise it. Moreover, the wrong choice of biocides may even generate an economic loss or environmental hazard. Generally, the application of biocides, H2S scavengers and nitrate-based treatment are one of the most effective world strategies to decrease microbiological contamination, which affects various areas of the oil and gas industry. These products have also been successfully applied to control bacterial growth in Polish natural gas wells. The issue of the influence of microorganisms and biomass on the permeability of reservoir rocks was also presented. In addition, the paper refers to biodegradation processes, that take place in the environment of drilling fluids. Also, the issue of choice of biocide/H2S scavenger preparations for industrial applications is presented. The choice of chemicals includes efficiency tests of nanoparticles in contaminated media.
Analysing Picture Books that Challenge Gender Stereotypes Multimodally
Authors: Moya-Guijarro Jesús , Ventola Eija
Published: September 2023

This paper identifies the transitivity strategies used in six picture books that aim to challenge gender stereotypes. They were selected because of the large number of commonalities they share; they are all authentic texts, written in English and were not created for experimental purposes. In addition, the selected stories are intended for children (four to nine years old). The theoretical frameworks adopted are SFL (Halliday 2004) and Visual Social Semiotics (Kress and van Leeuwen 2006, Painter et al. 2013). The findings show that the meaning load carried by embedded images (action plus reaction), together with verbal and mental processes of perception, provides essential cues for fostering progressive gender discourses. The analysis also demonstrates that metonymies are essentially used to highlight important aspects of the plot that challenge gender stereotypes.

The paper describes the ways in which participation in the Messina OVP (Online Video Project) on schools in the British Isles during and after the Covid crisis has proved beneficial for the students in question, both in terms of acquiring textual competences and as regards creating new interactive communities (Vasta and Baldry 2020; Baldry et al 2022).
Experiencia, ética y sujeto en el último Foucault
Authors: Pulido Cortés Oscar , Espinel Bernal Óscar Orlando , Díaz Bernal Juan Guillermo , Lara Buitrago Paola Andrea , Camargo Palencia Martín Emilio , Suárez Vaca María Teresa , Morales Mora Lola María
Published: September 2023

Este libro es una apuesta por relacionar tres conceptos/categorías (experiencia, ética, sujeto) que se convierten en posibilidades teórico/metodológicas para comprender el pensamiento de Foucault en la última etapa de producción académica y reconocer las potencialidades que ofrece para el desarrollo de investigaciones y estudios en los diversos campos de las ciencias humanas y sociales, pero principalmente, en la esfera de la educación y la filosofía. Esta hipótesis de trabajo se asume describiendo cómo Foucault en esta última etapa de su trabajo realiza un tránsito en la manera de comprender el poder desplazándose desde el esquema de la lucha de fuerzas (agonística, dominio o modelo bélico) hacia las artes de gobierno, privilegiando un nuevo grupo de tecnologías de constitución de sujetos que están en la frontera entre las tecnologías de poder y las tecnologías del yo. Tales tecnologías son identificadas como tecnologías de gobierno y uno de sus rasgos fundamentales es que en su concepción producen condiciones de aceptabilidad que conducen a los sujetos, convencidos de su agenciamiento en medio de espacios de libertad, a tomar decisiones y establecer códigos de conducta y valoración. Lo interesante de esta tecnología es que los objetivos y escenarios de libertad son espacios creados, calculados y gestionados de tal manera que sea posible conducir las conductas de los sujetos mediante la confluencia e identidad de intereses.
Tras las heridas de lo que somos, arte y nihilismo en la Era del vapor
Authors: Ávila Vásquez Manuel Oswaldo
Published: September 2023

El libro busca reflexionar a propósito del nihilismo en la
época de su consumación. Hacer el diagnóstico de nuestro
propio tiempo, de lo que somos. Así, el asunto que nos mueve
es la pregunta por el sentido de nuestra época y su posible
interpretación. Y esto, en una época en la que, gracias al
nihilismo y sus innumerables expresiones, se ha terminado
por intensificar la descomunal grieta que ha caracterizado la
relación existente entre los seres humanos y de ellos con la
naturaleza. Una grieta tan enorme como aquella hecha arte
en la obra de Doris Salcedo Shibboleth. De ahí que, la presente
indagación tenga como objetivo pensar el nihilismo a partir
de un “diálogo pensante” con el arte, hacer patente la herida
que somos, a partir de un diálogo sensible con la filosofía. Hoy
estos dos diálogos no solo se deben implicar mutuamente,
sino constituirse en una urgencia si se quiere trascender el
mero ejercicio académico del filosofar.

Published: September 2023

XVIII. yüzyılın büyük çoğunluğunda daha çok askeri alanla sınırlı kalan, fakat yüzyılın sonlarına doğru kapsamı daha da büyüyen batılılaşma yönündeki değişim ve dönüşüm politikaları, Tanzimat’la birlikte topyekûn niteliğine kavuşmuştur. Bu durum, neredeyse tamamen devlet adamlarının öncülüğünde gerçekleşen ve daha çok devlet kurumlarında değişimi öngören batılılaşmaya, XIX. yüzyılın ortalarından sonra, sivil bir boyut kazandırmıştır. Beyoğlu ise bunun merkezi durumundadır. Beyoğlu, tutum ve davranışlarıyla, görünüm ve yaşayış tarzlarıyla Avrupalılar gibi olmak anlamına gelen alafrangalığın merkezi haline gelmiştir. Buna karşılık Haliç’in hemen karşı yakasındaki semtlerde yaşayanlar geleneksel hayatlarına devam edip, ülkenin zor zamanlarında canlarıyla ve mallarıyla sorumluluk üstlenmeye devam etmişlerdir. Böylelikle iki ayrı İstanbul oluşmuştur: Alafranga İstanbul, alaturka İstanbul. Bu araştırma Alafranga İstanbul’u temsil eden Beyoğlu’nu konu edinmekte, batılılaşma adı altında Beyoğlu’nda yaşananları ortaya koyma amacı taşımaktadır.
Keabsahan Penutupan Perbatasan oleh Spanyol Selaku Negara Anggota Uni Eropa dalam Menghadapi Pandemi Covid-19
Authors: Sumhudi Faizin Achmad
Published: September 2023

AbstractThis article aims to identify and analyze the legitimacy of the border closure by Spain against Portugal as a member state of the European Union in the face of the Covid-19 pandemic. This article is a normative legal research that used a combination of the statute approach and the conceptual approach. The closing of the border by Spain is basically an action that is contrary to the Treaty on Establishing the European Union which requires the opening of borders, but the Covid-19 pandemic is an urgent situation that forces Spain to close its border with Portugal for the health and safety of its citizens. So the closing of the border by Spain is a justifiable action because it has a strong legal basis, namely Article 43 of the Spanish Constitution and Article 4 of the International Convention on Civil and Political Rights (ICCPR).
Keywords: Sovereignty, European Union, Border, Covid-19
AbstrakArtikel ini bertujuan untuk mengetahui dan menganalisis keabsahan penutupan perbatasan oleh Spanyol terhadap Portugal selaku negara anggota Uni Eropa dalam menghadapi Pandemi Covid-19. Artikel ini merupakan penelitian hukum normatif yang menggunakan kombinasi antara pendekatan perundang-undangan (statute approach) dan pendekatan konseptual (conceptual approach). Terhadap artikel ini, diperoleh kesimpulan bahwa pada dasarnya penutupan perbatasan ini akan menjadi tindakan yang berlawanan dengan Traktat Pembentukan Uni Eropa yang menghendaki terbukanya perbatasan sehingga memudahkan laju perdagangan barang dan jasa, akan tetapi pandemi Covid-19 adalah sebuah keadaan mendesak yang memaksa Spanyol harus menutup perbatasannya dengan Portugal demi kesehatan dan keselamatan warga negaranya. Maka penutupan perbatasan yang dilakukan oleh Spanyol merupakan tindakan yang dapat dibenarkan karena memiliki dasar hukum yang kuat, yaitu Pasal 43 Konstitusi Spanyol dan Pasal 4 Konvensi Internasional mengenai Hak Sipil dan Politik (ICCPR).

The Effect of The Minimum Age Limit for Marriage After The Enactment of Law Number 16 of 2019 Concerning Amendments to Law Number 1 of 1974 Concerning Marriage on The Determination of Marriage Dispensation at The Lumajang Religious Court
Authors: Muhammad Faiqul Hammam Novriansyah
Published: September 2023

AbstractMarriage is a legal act. As a legal act, the legal subject who conducts an event must meet the requirements. One of the requirements for humans as legal subjects to be able to be declared capable of carrying out legal actions is to be mature, while the determination of the age limit of children contained in the construction of legislation in Indonesia varies. Likewise, the age limit relates to the rights given to someone when he is considered capable of acting in law, in this case, in carrying out marriage. Marriage is not only an inner bond but a bond between the two. Inner birth ties in marriage mean that between the husband and wife in question, there must be a genuine intention to create a happy and eternal family. Generally, every person who wants a family is sure that his household will want to live harmoniously. Keywords: Marriage; Immature People; Quality Offspring.

The aim of this study was to determine the prevalence and distribution of dermatologic diseases and treatments in pediatric patients between the ages of 0-2 and the relation between skin diseases and age, gender and application year in private healthcare providers. The study was retrospectively analysed and conducted at dermatology department in a private hospital and private dermatology clinics. A total of 482 patients aged 0-2 years of outpatient admissions from January 1, 2015, to December 1, 2022 were included the study. The most common diseases group were eczemas (53.6%), nevus and benign skin tumors (8.3%), viral diseases (6%), pigmentation disorders (5.7%), and parasitic infections (4%). The dermatitis group was statistically significantly higher in 0-1 age group than 1-2 age. Atopic dermatitis was the most common diagnosis. The viral infections, parasitic infections, nail diseases, and dermatoses due to physical factors were higher in 1-2 age group (p<0.05). Benign skin tumors were commonly observed in girls and 0-1 age group (p<0.05). The topical treatment were usually prescribed to the patients. Systemic treatment was commonly prescribed in 1-2 age (p=0.007) and follow-up decision was usually given to girls than boys (p=0.001). Viral and bacterial infections were observed in higher rates after coronavirus disease 2019 pandemic (p<0.05). New studies in specific pediatric age groups will help to better understand the frequency of dermatological diseases and treatments and also studies conducted at different levels of health care may contribute better to develop health care policies, designing preventive health services and education programmes.

Published: September 2023

INTRODUÇÃO: O câncer de próstata é o segundo tipo mais comum de neoplasia maligna entre os homens e com maior prevalência em idosos, a idade é um fator de risco notável para a incidência e mortalidade por essa doença. Considera-se que os hábitos de vida, genética e fatores ambientais também interferem para o desenvolvimento da doença, o que demanda estratégias de investigação precoce das neoplasias malignas para possibilitar sucesso no tratamento e sobrevida. OBJETIVO: Descrever e avaliar o perfil epidemiológico de óbitos por neoplasia maligna de próstata no Estado do Tocantins, Brasil, durante os anos de 2014-2019. METODOLOIGIA: Trata-se de um estudo epidemiológico utilizando dados disponibilizados na base de dados do DATASUS e pelo Sistema de Informação sobre Mortalidade (SIM). RESULTADOS: Foram retirados 752 casos no período do estudo. Demonstrou-se que homens brancos, maiores de 70 anos, com, no mínimo, 3 anos escolaridade, casados e moradores de microrregiões com maior concentração populacional ao apresentarem municípios com mais de 50 mil habitantes, com o local do óbito sendo os hospitais, compõem o perfil epidemiológico dos óbitos por neoplasia maligna de próstata no estado do Tocantins entre 2014 e 2019. Denotou-se pouca variação nas variáveis analisadas entre os anos estudados, o que evidencia pouca mudança do cenário estadual. CONCLUSÃO: Tendo em vista o cenário de desigualdade ao enfrentamento do câncer prostático no Tocantins, a detecção e o tratamento precoce a partir de programas de rastreio com profissionais capacitados em populações vulneráveis em áreas de menor acesso aos serviços de saúde compõe medidas eficazes de prevenção para alterar a situação de saúde.permitiu identificar a prevalência de casos e óbitos em indivíduos do sexo masculino sendo jovens a faixa etária com mais internações e adultos com mais óbitos.

Published: September 2023

This note describes an observation of a Dusky Woodswallow Artamus cyanopterus employing a seldom observed and unusual defensive behaviour against a Peregrine Falcon Falco peregrinus. Instead of mobbing or fleeing, the Woodswallow hid beneath a branch to avoid detection and potential predation. We discuss various predator-avoidance and defensive behaviours and explain the advantages of hiding as a quick and safer survival strategy. This observation reveals additional tactics used by woodswallows and expands our understanding of avian predator avoidance. Understanding these unconventional strategies broadens our knowledge of defensive behaviours in passerine birds
Stochastic modeling and computational simulations of HBV infection dynamics
Authors: Alsammani Abdallah
Published: September 2023

This study investigates the stochastic dynamics of hepatitis B virus (HBV) infection using a newly proposed stochastic model. Contrary to deterministic models that fail to encapsulate the inherent randomness and fluctuations in biological processes, our stochastic model provides a more realistic representation of HBV infection dynamics. It incorporates random variability, thereby acknowledging the changes in viral and cellular populations and uncertainties in parameters such as infection rates and immune responses. We examine the solution's existence, uniqueness, and positivity for the proposed model, followed by a comprehensive stability analysis. We provide the necessary and sufficient conditions for local and global stability, offering deep insight into the infection dynamics. Furthermore, we utilize numerical simulations to corroborate our theoretical results. This research provides a robust tool for understanding the complex behavior of HBV dynamics, contributing significantly to the ongoing quest for more effective HBV control and prevention strategies.
Dilemma and Countermeasures for Digital Governance of Renewable Energy in China under the "Dual Carbon" Goal
Authors: Lin Jia-xin
Published: September 2023

Digital technology makes energy systems more dynamic, efficient, reliable and sustainable. Promoting the digital governance of renewable energy is not only a key part of energy transformation, but also an important initiative to cope with the global energy crisis, which provides a new impetus for realizing the goal of net-zero emissions. In order to achieve the "dual-carbon" goal, China has been actively promoting energy reform and enhancing the wide application of digital technologies in the development and utilization of renewable energy. The digital governance system and governance capacity of renewable energy is an important support for the modernization of the national governance system and governance capacity. Although the digital governance of renewable energy in China has better policy support and advantages, the dilemmas it faces are still relatively prominent, including unsound laws and policies, insufficient governance capacity, and security loopholes in digital technology, etc. Therefore, this paper proposes a problem-oriented approach to the digital governance of renewable energy. Therefore, this paper puts forward problem-oriented optimization suggestions to innovate the legal system of renewable energy digital governance, promote the digital transformation of China's renewable energy industry, provide development space for renewable energy digital governance in a diversified mode, and enhance the digital governance capacity by improving the renewable energy security system.
Structure and High-Temperature Oxidation Properties of an Al-Co-Y diffusion Coating prepared on TiAl-Nb alloy at a Low Temperature

Published: September 2023

Abstract: An Al-Co-Y diffusion coating was prepared on a TiAl alloy by pack cementation process at a low temperature range of 650-720 ℃. The influence of different activators and co-deposition temperatures on the coating’s microstructure and formation process, and high temperature oxida-tion performance was studied. The results showed that NaF was a more suitable activator for preparing the Al-Co-Y diffusion coating on TiAl alloy compared to NH4Cl and AlCl3. A more compact coating structure can be obtained when deposition was performed at 680 ℃ using NaF as the activator. The coating was mainly composed of a TiAl3 outer layer, a TiAl2 inner layer, and a thin Al-rich TiAl inter-diffusion layer. The growth of the coating exhibited a positive linear correlation between coating thickness increase and the square root of deposition time. The high-temperature oxidation tests showed that a dense scale mainly composed of Al2O3 and a small amount of TiO2 formed on the coating after oxidation at 950 ℃ for 100 h. The scale possessed excellent high-temperature oxidation resistance, with a parabolic rate constant of the oxidation weight gain approximately 4.9×10-3 mg2/cm4 h, which is lower than that of the TiAl substrate by about three orders of magnitude, and lower than that of the pure Al diffusion coating more than one order of magnitude.

Published: September 2023

Low Pathogenicity Avian Influenza virus subtype H9N2 causes decreased egg production and two of the four defined H9N2 poultry lineages (G1 and Y280) have been associated with human infections. The high positive test results for the H9N2 virus in the LBMs of the Greater Jakarta area in 2021 can be a source of transmission for the surrounding area. This study aims to determine the prevalence and risk factors that play a role in the H9N2 contamination in the LBMs to obtain a multivariate analysis model. A cross-sectional study was conducted on 87 vendors and 124 broiler chickens from 44 LBMs randomly selected in Tangerang City, North Jakarta, and Bekasi City. Samples were taken as equipment swabs at the stall of poultry carcass vendors, tracheal swabs, and cloacal swabs of broiler chicken. The test used was Real-Time Reverse Transcription Polymerase Chain Reaction. Data analysis was performed using univariate, bivariate, and multivariate analysis with logistic regression. The prevalence of H9N2 virus contamination at the LBM level in Greater Jakarta in 2022 was 77.27% (95% CI, α 7%), while the prevalence at the vendor level was 54.02% (95% CI, α 5%). The risk factors for H9N2 virus contamination with a significant p-value<0.05 include the positive results on equipment swab samples, positive results on both equipment and broiler swabs, and the use of carcass sink.  The multivariate analysis model of H9N2 virus contamination at the vendor level was Logit P (H9N2=1 | x) = 0.29924 - 2.42176PPE + 1.58691carcass sink. The risk factor contributing to increase H9N2 contamination is using carcass sinks, while PPE is the one that reduces H9N2 contamination.

Published: September 2023

Red ginger is one of the commodities much needed by the people of Indonesia. The increase in public demand has not been matched by an increase in red ginger production. Efforts to increase red ginger production can be done with effective fertilization. This study aims to determine the appropriate dose of ZA+KCl fertilization for good growth and yield of red ginger. This research was conducted in March-August 2021 in the experimental area of Pelem, Wonorejo, Jatiyoso, Karanganyar, Central Java with coordinates 7°43'24.7”S 111°05'31.2”E with an altitude of 762  ASL. This study used a Randomized Completed Block Design (RCBD) with one factor and 4 treatments, namely D0 (control), D1 (ZA 225 kg.ha-1+KCl 50kg.ha-1), D2 (ZA 450 kg.ha-1+ KCl 100 kg.ha-1) and D3 (ZA 675 kg.ha-1+KCl 150 kg.ha-1) were repeated 6 times each. The results showed that the application of several doses of fertilizer did not increase plant height, number of leaves, dry weight of straw but could increase the number of tillers per clump by 37.11% and the number of tillers per plot by 27.10%. The results of regression analysis showed that D2 had a trend to increase fresh weight and storage weight of rhizomes with an average of 1.9 t.ha-1 and 1.5 t.ha-1. This research needs to be further developed by improving environmental influences to increase the growth and yield of red ginger.

Using the 2021 Public Health Workforce Interest and Needs Survey, we examined the association between local public health agency rural versus urban location in the United States (n = 29 751) and individual local public health staff reports of skill proficiencies, training needs, turnover risk, experiences of bullying due to work as a public health professional, and posttraumatic stress disorder symptoms attributable to COVID-19.

Results. Rural staff had higher odds than urban staff of reporting proficiencies in community engagement, cross-sectoral partnerships, and systems and strategic thinking as well as training needs in data-based decision-making and in diversity, equity, and inclusion. Rural staff were also more likely than urban staff to report leaving because of stress, experiences of bullying, and avoiding situations that made them think about COVID-19.

Conclusions. Our findings demonstrate that rural staff have unique competencies and training needs but also experience significant stress.

Public Health Implications. Our findings provide the opportunity to accurately target rural workforce development trainings and illustrate the need to address reported stress and experiences of bullying. (Am J Public Health. 2023;113(6):689–699. https://doi.org/10.2105/AJPH.2023.307273 )
Public Health Impacts of Vaccines for COVID-19 and Beyond: Opportunities to Overcome Technical and Regulatory Barriers for Randomized Trials
Authors: Kennedy-Shaffer Lee
Published: September 2023

The COVID-19 pandemic has revealed the importance of the population-scale effects of both diseases and interventions. Vaccines have had an enormous impact, greatly reducing the suffering caused by COVID-19. Clinical trials have focused on individual-level clinical benefits, however, so the broader effects of the vaccines on preventing infection and transmission, and their overall effect at the community level, remain unclear.

These questions can be addressed through alternative designs for vaccine trials, including assessing different endpoints and randomizing at the cluster instead of individual level. Although these designs exist, various factors have limited their use as preauthorization pivotal trials. They face statistical, epidemiological, and logistical limitations as well as regulatory barriers and uncertainty.

Addressing these hindrances through research, communication, and policy can improve the evidence base of vaccines, their strategic deployment, and population health, both in the COVID-19 pandemic and in future infectious disease outbreaks.

To assess factors associated with timely second-dose completion, we analyzed COVID-19 vaccine data from community-based and mobile vaccine clinics in Maryland. Overall, 85.3% of patients received a timely second dose. Factors associated with a timely second dose included Latino ethnicity (adjusted odds ratio [AOR] = 1.5; 95% confidence interval [CI] = 1.1, 2.0) and receipt of the first dose at community-based vaccine clinics (AOR = 2.1; 95% CI = 1.8, 2.5). Future health initiatives for underserved communities should focus on establishing vaccine clinics in trusted community spaces with culturally sensitive support.

COVID-19 has disproportionately affected Indigenous communities. The Whiteriver Service Unit (WRSU) took an integrated public health–health care system delivery approach in collaboration with the White Mountain Apache Tribe to decrease the case fatality rate (CFR). The WRSU performed daily data analyses identifying risk factors, expeditiously treating and proactively vaccinating people during at-home visits. The WRSU’s CFR was 0.3% lower than Arizona’s (P = .04). Among communities disproportionally affected, an integrated approach using data to drive real-time decision-making among a culturally competent workforce can contribute to decreased CFR.

Impact of a Permitless Concealed Firearm Carry Law in West Virginia, 1999–2015 and 2016–2020
Authors: Lundstrom Eric W. , Pence Jacob K. , Smith Gordon S.
Published: September 2023

We used firearm mortality and sales data to assess the impact of HB 4145, a May 2016 law that legalized concealed firearm carry without a permit in West Virginia. Firearm mortality was significantly higher (29%) in the years after the enactment of the law; handgun mortality was also higher (45% increase), whereas long gun deaths and firearm sales were unaffected. This may suggest that HB 4145 increased rates of firearm-related mortality in West Virginia without affecting firearm sales in the state.

Published: September 2023

Background:

Sacral (S1) pedicle screw misplacement in posterior percutaneous fixation (PPF) can be related to anatomical variability and a lack of reliable radiographic landmarks. This study highlights a reproducible anatomical landmark (the “V” sign) for the safe localization of the S1 pedicle entry point under fluoroscopy.

Methods:

Human cadavers (n = 14) were dissected for the anatomical description of the “V” landmark and its relationship with the entry point of the S1 pedicle screw. The “V” landmark was defined medially by the lateral border of the superior articulating process of S1 and laterally by the posterior projection of the sacral ala. The mean distance was measured between the bottom point of the “V” landmark and the anatomical entry point to the S1 pedicle (V-S1 entry point distance). A similar measurement was conducted on computed tomography (CT) scans of 135 patients who underwent PPF using the “V” sign as a landmark for S1 pedicle screw placement (270 screws). These were retrospectively evaluated for appropriateness of S1 screw entry points and for proper S1 screw alignment and breaches.

Results:

In the 14 cadavers, irrespective of the laterality and sex, the V-S1 entry point distance averaged 11.7 mm. On the medial-lateral axis, all entry points converged within 2 mm of a vertical line intersecting the base of the “V.” Additionally, the CT scan analysis (135 patients, 270 screws) revealed an optimal entry point for 100% of the screws and a 3.3% (n = 9 screws) breach rate. Six of the 9 identified breaches were minor, and only 1 (0.4% of the 270 screws) warranted revision.

Conclusions:

The “V” sign serves as a reliable anatomical and radiographic landmark for identifying the S1 pedicle entry point under fluoroscopic guidance. This landmark can help surgeons overcome the radiographic ambiguity of the sacral anatomy and ultimately reduces the rate of S1 pedicle screw misplacement.

Published: September 2023

Background: Nonvariceal upper gastrointestinal bleeding (NVUGIB) is one of the most common medical emergencies and often represents a life-threatening event. The aim of this study is to find potential predictive factors associated with 30-day mortality in patients with NVUGIB. Methods and Results: Our prospective study was conducted in Mother Teresa Hospital between May 2022 and December 2022. A total of 224 patients (aged >18 years) with NVUGIB were included in the study. Demographical and clinical characteristics, endoscopic findings, and laboratory tests were reviewed during a 30-day follow-up period. Logistic regression was employed to identify the independent predictors of mortality. The mean age of the 224 patients enrolled in the study was 63.21±16.3 years and most patients (72.8%) were male. One hundred fifty (66.9%) patients had comorbidities. The most common endoscopic diagnoses underlying NVUGIB episodes were duodenal ulcers (53.1%). Recurrent bleeding was recorded in 50(22.3%) patients. Out of 224 patients included in the study, 24(10.7%) died within 30 days of admission, 20(8.9%) died during hospitalization, and 4(1.8%) died after discharge. The mean age of death was 76.42±12.59 years; 95.8% of deaths were associated with one or more major comorbidities. In the multivariate logistic regression, after the exclusion of confounding factors, low red blood cell (RBC) (P=0.043, OR=0.413, CI 95%: 0.176-0.974), warfarin (P=0.036, OR=10.547, CI 95%: 1.165-95.462), and Rockall score (RS) >5 (P=0.034, OR=4.107, CI 95%: 1.114-15.139) were found to be independent predictive factors for mortality. Conclusion: The 30-day mortality rate remained high after NVUGIB, especially during hospitalization. Low RBC, warfarin, and RS>5 were independent factors of mortality in patients with NVUGIB.

Published: September 2023

Background: All types of chromosomal aberrations have an impact on the development of dermatoglyphs, which changes both their quantitative and qualitative characteristics. This study aims to compare the quantitative characteristics of dermatoglyphs between individuals with Down syndrome and those with normal karyotypes in the Kosova Albanian population. Methods and Results: The quantitative characteristics of digitopalmar dermatoglyphs were analyzed on 104 individuals (54 men and 50 women) with Down syndrome from Kosova's Albanian population. The dermatoglyphs of 403 Albanians from Kosova with normal karyotypes (the control group) were also analyzed quantitatively. Using the method devised by Cummins and Midlo, dermatoglyph traces were obtained and analyzed. We analyzed the quantitative features of both the dermatoglyphs of the fingers and the dermatoglyphs of the palms of the hands. Moorhead and Seabright's peripheral blood culture technique was utilized to analyze the karyotypes of individuals with Down syndrome. A total of 40 dermatoglyphic variables were analyzed. When the quantitative dermatoglyphic features of men with Down syndrome and the control group were compared, significant differences were discovered in 20 of the dermatoglyphic variables. Significant differences were discovered in 21 of the dermatoglyphic variables when the features of women with Down syndrome and the control group were compared. One of the most distinctive characteristics of Down syndrome was the breadth of the atd angle, which should be taken into consideration. Compared to the control group's males and females, the males and females with Down syndrome exhibit wider atdT angles (161.91° vs. 92.60° [P<0.0001] and 165.48° vs. 94.75° [P<0.0001], respectively). Conclusion: The size of atd angles is the factor that most closely identifies people with Down syndrome.
