Objectives: To determine the frequency of pre-hospital aspirin use in patients presenting with ST- segment elevation myocardial infarction and to assess the demographic and clinical characteristics of the patients taken pre-hospital aspirin.
Methodology: It was a prospective study conducted at tertiary care hospital for the duration of six months. About 657 patients aged between 18-80 years, of either gender and diagnosed with ST-elevation myocardial infraction were included in the study. Use of pre-hospital aspirin after symptoms was assessed in all patients, then followed and outcomes such as discharge status and length of hospital in days were evaluated.
Results: Overall mean age was 54.60±12.06 years and most of them were males (79.1%). About 254 patients (38.7%) received aspirin before transfer to hospital and 403 patients (61.3%) received aspirin after arrival in hospital. Frequency of pre-hospital use of aspirin was significantly associated with gender (p=0.001), educational status (p=0.006), and monthly income (p=0.003). The mean rank of length of hospital stay was similar significantly lower in STEMI patients who received pre-hospital aspirin as compared to those who did not receive pre-hospital aspirin (p=0.001). Moreover, the death rate was lower in patients with pre-hospital aspirin administration as compared to those who did not receive pre-hospital aspirin (1.2%vs2%). However, the difference between pre-hospital aspirin use and discharge status was not statistically significant (p=0.434).
Conclusion: Frequency of pre-hospital aspirin use was lower in patients with STEMI. Gender, educational status, and socio-economic status were the significant factors for pre-hospital aspirin use.

Objectives: The presence of concomitant obstructive coronary artery disease (CAD) in patients with valvular heart disease (VHD) carries significant prognostic implications. Therefore, the objective of this study was to determine the frequency and severity of obstructive CAD in patients undergoing valvular heart surgery for rheumatic heart disease (RHD) at a tertiary care hospital in Karachi, Pakistan.
Methodology: This descriptive study included patients of either gender, between 40 to 70 years of age, diagnosed with RHD on transthoracic echocardiography, and undergone valvular heart surgery. As a routine, pre-operative diagnostic coronary angiography was performed and the presence and severity of obstructive CAD were recorded.
Results: Among 126 patients, 73% (92) were male, and the mean age was 48.3 ± 7.1 years. Smoking was the most common risk factor with a frequency of 22.2%, followed by hypertension (7.1%) and diabetes (4.8%). Obstructive CAD was observed in 24.6% with 19.4% single-vessel disease, 16.1% with two-vessel disease, and 64.5% with three-vessel disease. The presence of obstructive CAD was found to be positively associated with older age (p=0.040) and type of RHD (p=0.048).
Conclusion: The obstructive concomitant CAD is prevalent in around 1/4th of patients, most of them with multi-vessel diseases, undergoing valvular heart surgery for rheumatic heart disease. It has been further observed that older age and the type of RHD are positively associated with the incidence of concomitant CAD in these patients.

Published: April 2023

Objectives: This is a real world prospective study to evaluate the effects of Neprlysin Inhibition (ARNI) using sacubitril/valsartan in patients with heart failure with reduced ejection fraction (HFrEF).
Methodology: This was an outpatient study on patients of HFrEF (EF<40%) and stable blood pressure after obtaining informed consent. Consecutive patients were enrolled and followed at 6 and 12 weeks. Detailed clinical and echocardiographic examinations were performed on all visits. Biochemistry evaluating ProBNP, renal profile, HbA1C and electrolytes were performed in 24 patients at baseline and follow-up.
Results: We enrolled 80 patients, but 63 patients could be followed. Mean age was 53.54±13.32 years and 55% were males. After 12 weeks treatment improvement in NYHA functional class was seen in 66% and improvement by more than one grade in 31% (p<0.01). Pro-BNP reduced from 3552.71±1804.74 at the baseline to 723±930 on the second FU visit (p<0.002).  Structural improvement was seen in 33% of patients. Left ventricular (LV) end-diastolic diameter (EDD) reduced by 3.49 mm and LV end systolic diameter (ESD) by 3.97 mm (p<0.014). Fractional shortening (FS) increased by 2.07% and EF by 3.52 (p<0.01). Patients tolerated the drug well, but most could not tolerate the higher recommended dosage. Renal status, electrolytes, and HbA1C did not alter significantly.
Conclusion: Treatment with sacubitril/valsartan in addition to the guideline directed medical therapy (GDMT) resulted in marked reduction in ProBNP, significant improvement in functional class and enhancement of cardiac pumping activity with reduction in LVEDD and LVESD and improvement in FS and EF.

Objectives: Objective of this study was to assess the difference in terms of presentation and in-hospital course between patients with right vs. left dominant arterial circulation undergoing “primary percutaneous coronary intervention (PCI)” for culprit proximal left anterior descending artery (LAD).
Methodology: We included consecutive adult (≥18 years) patients diagnosed with STE-ACS undergoing primary PCI for culprit proximal LAD. Patients were categorized into right vs. left dominant circulation on left heart catheterization. Demographic, clinical characteristics, presentation, and hospital course were compared between the matched (propensity matched) and unmatched cohort of patients with right vs. left dominance.
Results: We included 775 patients, out of which 81.3% (630) were males and mean age was 54.59 ± 11.3 years. On coronary angiogram left dominance was observed in 14.3% (111). Single vessel disease was higher with left compared to right dominant system, 53.2% vs. 43.5%, respectively. The rate of slow flow/no-reflow (15.4% vs. 7.2%; p=0.0.230), heart failure (9.3% vs. 6.3%; p=0.299), and in-hospital mortality (5.1% vs. 3.6%, p=0.493) were not different between right vs. left dominance, respectively. In the matched cohorts, the frequency of slow flow/no-reflow (15.3% vs. 7.2%; p=0.056), heart failure (6.3% vs. 6.3%; p>0.999), and mortality (5.4% vs. 3.6%, p=0.493) were not different between right vs. left dominance, respectively.
Conclusion: No significant increase in complications and outcomes is witnessed among patients with left dominant arterial circulation undergoing primary PCI for culprit proximal LAD. However, careful handling of left main during intervention is warranted due lack of support from right system.

Published: April 2023

Objectives: To assess the knowledge about valvular heart disease among the patients who are already diagnosed with rheumatic valvular heart disease (RVHD).
Methodology: In this cross-sectional study was conducted at the outpatient of a tertiary care cardiac centre. We included consecutive patients of either gender between 18 to 60 years of age with the established diagnosis of RVHD. Their knowledge and awareness regarding the disease itself and regarding its primary and secondary prevention and treatment options was assessed with the help of a structured self-developed questionnaire.
Results: Among the study sample of 505 patients, 255 (50.5%) were male and overall mean age was 37.3 ± 10.9 years. A majority (90.3%) of the patients had household income of ≤ PKR 40,000 and 35.3% were illiterate. More than 41% were not aware of their diagnosis, 40% were aware of childhood infection as the cause of RVHD. About 40% of the patients could not recall history of fever/sore throat in past. About 19.8% of the patients considered percutaneous transvenous mitral commissurotomy as complete cure for RVHD and 46.3% of the patients were not aware of a prophylactic treatment. Only 33.9% considered the need to maintain good dental hygiene as part of the prophylactic treatment.
Conclusion: High incidence of lack of awareness regarding their disease and its prophylaxis in our study population is alarming. To improve the RHD awareness, sessions and seminars should be arranged in the general population. Further studies are required to identify the cause and hence identifying measures to improve awareness.

Counting prime numbers in arithmetic sequences
Authors: Suárez Suri Pedro Roberto
Published: April 2023

This paper presents the theoretical elements that support the calculation of the prime number counting function, π(x), based on properties of the sequences (6n-1) and (6n+1), n ≥ 1. As a result, Sufficient primality criteria are exposed for the terms of both sequences that support a deterministic computational algorithm that reduces the number of operations in calculating the function π(x) by exonerating all multiples of 3 from the analysis. In analyzing the primality of a particular term, the divisions by factor 3 are excluded. Such an algorithm can be applied to the search for prime numbers in each sequence separately, a possibility that allows approximately half the time of number search in practical applications.

Published: April 2023

Self-healing concrete has emerged as a promising solution to mitigate the degradation and deterioration of concrete structures over time. However, to fully realize the potential of self-healing concrete in practical applications, its long-term durability needs to be thoroughly investigated. This study aims to evaluate the long-term durability of self-healing concrete by assessing its resistance to fatigue, creep, and corrosion over an extended period. Experimental testing will be conducted on different types of self-healing concrete samples, including those containing different healing agents and those subjected to different environmental conditions. The mechanical properties, such as compressive strength, flexural strength, and toughness, will be evaluated periodically to assess the effectiveness of the self-healing mechanism over time. The durability performance of the self-healing concrete will also be compared to traditional concrete to determine its advantages and limitations. The results of this study will provide a better under-standing of the long-term durability of self-healing concrete and will contribute to its wider adoption in the construction industry.

Authors: Das Jayabrata , Maiti Debabrata
Published: April 2023

Transition metal catalyzed remote C-H activation offers a powerful tool to modify architecture of organic molecules. Remote or distal C-H activation of aromatic and aliphatic compounds presents more challenge than proximal sites due to the inaccessibility of these sites in formation of energetically favorable organometallic pre-transition states. Nonetheless, recent years have witnessed remarkable progress in reaching out and functionalizing distal C-H bonds. With the advancement of this field, synthetic modifications of organic molecules have become more step and atom economical, and have shown great promise to revolutionize synthetic organic chemistry.

Authors: Ahmed Ahmed Abdulrahman , Hussein Juma’a Qadir
Published: April 2023

The structure and production of persuasive writing are regarded to be significantly influenced by metadiscourse, a new and fascinating area of study that is based on the norms and expectations of those involved. Metadiscourse markers are observed as social activities that encourage contact among writers, readers, speakers, and listeners. In other words, authors must represent their identities in their writings in a way that makes sense to their readers. However, some words are used in writer's identity study in a way that can lead audiences to perceive them incorrectly. The primary goals of this study were to examine the metadiscourse indicators that were used most frequently in Q1 Scopus-index articles. The 10 Q1 Scopus-indexed linguistics articles from the Journal of Pragmatics that were used as study data ranged from (2020 to 2022). On the basis of Hyland's (2005a) model of metadiscourse markers, the data were qualitatively examined. The findings indicate that 2407 metadiscourse markers were employed in the entire dataset. There were 1785/74.1587 % of interactive metadiscourse markers compared to 622/25.8412 % of interactional metadiscourse markers.. Remarkably, it was found that metadiscourse markers were regarded as an essential tool for enhancing effective communication between authors and readers, establishing helpful possibilities for how well readers comprehend the material, and aiding them in differentiating facts from opinions while reading a text. Finally, the study suggests expanded use of metadiscourse-based analysis in academic writing generally and in high rank research articles in particular.

Authors: Khalaf Meethaq Khamees , Al Hiyali Huda Tariq Juma’a Abed
Published: April 2023

The aim of the current study is to investigate the discoursal function of modality in presidential victory speech. The victory speech of Biden in 2020 has been selected as the data source in the present qualitative study. The data of this study has been attained through purposive sampling from ‘The Washington Post’. The analysis is restricted to clauses that are found in the speech by tabulated them and analyzing each type of modality. Modality is used as a linguistic system which reflects the social role, power, and the type of formality relationship. In addition, modality can reflect the speaker judgments toward certain topics. To this end, The Hallidayan Systemic Functional Linguistics (SFL) 2014 was adopted as a theoretical framework to study language structure and function. Major findings reveal that three types of modality were used in Biden’s speech. Inclination was used (20) times in the speech and probability was used (26) times, and obligation was used only (4) times. In addition, the fourth type (usuality) was not used in Biden’s victory speech.

DEPRESSÃO INFANTIL: UMA REALIDADE INVISÍVEL
Authors: Ferreira Janayna dos Santos
Published: April 2023

O objetivo deste trabalho é trazer a viabilização de uma maior compreensão acerca do que é a depressão infantil, assim como das questões intrínsecas da mesma, como na forma da realização do diagnóstico. Sua metodologia consiste em uma revisão bibliográfica, de natureza descritiva. A coleta de dados foi realizada nas bases SciELO, PubMed, BVS e Google Acadêmico, nos idiomas inglês e português, publicados nos últimos 5 anos (2017-2022). Trinta textos foram avaliados na íntegra. Considerando os critérios de inclusão e exclusão, apenas 11 artigos foram selecionados para análise. Depois desta excursão feita pelo tema, percebe-se a necessidade de um olhar mais aguçado sobre nossas crianças, precisando de cautela, pois se de um lado há a preocupação em diagnosticar e tratar o mais rápido possível a depressão infantil, por outro lado deve-se tomar cuidado para não confundir estados normais do humor ou fases de desenvolvimento da criança com um quadro nosológico.
