Anorexia Nervosa (AN) is a disease with increasing prevalence and relatively high mortality that usually begins in adolescence. Patients with AN avoid food intake and may react specifically toward food images. We present a systematic review of fMRI studies with visual food stimulation in AN, based on a search through PubMed database under the recommendations of the PRISMA guidelines. After applying dates 2004.01.01-2021.01.01, we screened 319 papers and included 27 experimental designs, with only 7 studies focusing on adolescents. Adolescents with AN showed increased activity in the medial prefrontal cortex, the inferior frontal gyrus, the insula, the hippocampus, the fusiform gyrus, the parahippocampal gyrus and the cuneus when watching food images. Adult participants with AN revealed enhanced brain activity due to visual food stimuli in the fusiform gyrus, the inferior frontal gyrus, the lingual gyrus, the medial prefrontal cortex, the right dorsolateral prefrontal cortex, the right angular gyrus. There was deactivation detected in the parahippocampal gyrus, compared to healthy participants. We have found contrary reports according increased/decreased activation of the insula, the amygdala, the hippocampus, the hypothalamus, the anterior cingulate cortex, the thalamus, the orbitofrontal cortex in adults with AN. Although AN typically develops in adolescence, there is still very little fMRI research in this age group. Careful creation of a homogeneous group of study participants is an important factor determining the reliability and unequivocalness of the experiment. Only a detailed description of participants´ characteristics that may affect the results allows solid comparison of different studies´ findings.

Objective: This work evaluated the antioxidant defenses, anthropometric, oxidative and lipid profile parameters in hypertensive women and analyzed correlations between these variables to understand the impact of antioxidant defense in the development and progression of Systemic Arterial Hypertension (SAH). Design and Methods: The study included 154 women, 81 in the hypertensive group and 73 in the normotensive group. For the evaluation of oxidative stress parameters were analyzed the activity of the enzymes Superoxide Dismutase (SOD), Catalase (CAT), Glutathione S-Transferase (GST), vitamin C levels, Non-Protein SH groups (NPSH), Reactive Oxygen Species (ROS), Thiobarbituric Acid Reactive Substances (TBARS) and protein carbonylation. Total Cholesterol (TC), High-Density Cholesterol (HDL), LowDensity Cholesterol (LDL) and triglycerides, total height, body weight, Body Mass Index (BMI) and body fat percentage were measured. Student’s t-test and Pearson’s Correlations were performed. Results: Hypertensive women had higher body mass, fat percentage, BMI, TC, LDL and triglycerides and lower HDL. GST, SOD, CAT, vitamin C and NPSH were decreased in hypertensive women. Oxidative damage parameters were higher in the hypertensive group. Positive correlations were set in hypertensive women between Systolic Blood Pressure (SBP) and TBARS, SBP and ROS, SBP and LDL, PAS and triglycerides, LDL and TBARS, triglycerides and TBARS, triglycerides and ROS, and triglycerides and GST. Negative correlations were established between SBP and NPSH, LDL and NPSH, and triglycerides and NPSH in hypertensive women. Conclusion: The results suggest that oxidative stress, antioxidant defense reduction, lipid profile, body fat percentage and blood pressure itself interact with each other, being potential agents that favors the progression of SAH.

Soy protein is a natural component of soybeans and is known to provide a variety of health advantages. It offers advantages and is a different source of protein for folks who don’t consume meat. The purpose of this review is to familiarize readers with the value of soy beans in both the food and medical industries. Legumes, which also include peanuts, chickpeas, various beans, and pulses, contain soybeans. Soybeans are incredibly flexible because they can be made into meal, flour, and oil. Soy protein has roughly 25g of approved health claims per day, which is known to lower total cholesterol and LDL. Soy has a variety of powerful ingredients, including fiber, isoflavones, phytic acid, saponins, and trypsin inhibitors. Soy has been seen to have several harmful consequences. Numerous studies have raised concerns about the potential negative effects of it because of the allergens present and the antinutrient agents they contain, which prevent micronutrient absorption. It may also result in hypothyroidism because it lacks some essential amino acids, making it a source of incomplete protein. Additionally, it might have hormonal effects on infants later in life.

Soy consumption has been associated with many potential health benefits in reducing chronic diseases such as obesity, cardiovascular disease, insulin-resistance/type II diabetes, certain type of cancers, and immune disorders. These physiological functions have been attributed to soy proteins either as intact soy protein or more commonly as functional or bioactive peptides derived from soybean processing. These findings have led to the approval of a health claim in the USA regarding the ability of soy proteins in reducing the risk for coronary heart disease and the acceptance of a health claim in Canada that soy protein can help lower cholesterol levels. Using different approaches, many soy bioactive peptides that have a variety of physiological functions such as hypolipidemic, anti-hypertensive, and anti-cancer properties, and anti-inflammatory, antioxidant, and immunomodulatory effects have been identified. Some soy peptides like lunasin and soymorphins possess more than one of these properties and play a role in the prevention of multiple chronic diseases. Overall, progress has been made in understanding the functional and bioactive components of soy. However, more studies are required to further identify their target organs, and elucidate their biological mechanisms of action in order to be potentially used as functional foods or even therapeutics for the prevention or treatment of chronic diseases.

The Longitudinal Study of Adult Health (ELSA-BRASIL) is a multicentric and multidisciplinary cohort study aimed at investigating the incidence and risk factors of chronic diseases. Vitamin D deficiency has been associated with several comorbidities. In this context, the need to assess the impact of vitamin D on endothelial dysfunction in a large-scale study is justified. Thus, in this study, serum levels of vitamin D were determined by HPLC in 509 participants of the ELSA-BRASIL, and its association with endothelial function parameters by Peripheral Arterial Tonometry (BPA and PATratio). Reduced levels of vitamin D were shown to be associated with indicative measures of worse endothelial function. In the logistic regression model, the variables male sex, white color, increase in age, BMI, triglycerides, and vitamin D<30ng/mL were also indicative of worse endothelial function. In summary, vitamin D has presented an association with endothelial function, which may indicate a protective action of vitamin D to the vascular endothelium.

Published: March 2024

Coupling molecules to a quantized radiation field inside an optical cavity has shown great promise to modify chemical reactivity. In this work, we show that the ground state selectivity of the electrophilic bromination of nitrobenzene can be fundamentally changed by strongly coupling the reaction to the cavity, generating the \textit{ortho}- or \textit{para}-substituted products instead of the \textit{meta} product. Importantly, these are products that are not obtained from the same reaction outside the cavity. A recently developed \textit{ab initio} approach was used to theoretically compute the relative energies of the cationic Wheland intermediates, which indicate the kinetically preferred bromination site for all products. Performing an analysis of the ground state electron density for the Wheland intermediates inside and outside the cavity, we demonstrate how strong coupling induces reorganization of the molecular charge distribution, which in turn leads to different bromination sites directly dependent on the cavity conditions. Overall, the results presented here can be used to understand cavity-induced changes to ground state chemical reactivity, from a mechanistic perspective, as well as to directly connect frontier theoretical simulation to state-of-the-art, but realistic, experimental cavity conditions.
Anharmonic vibrational spectroscopy of germanium-containing clusters, Ge(x)C(4−x) and Ge(x)Si(4−x) (x = 0-4), for interstellar detection
Authors: Flowers Adam Mackenzie , Brown Alex , Klobukowski Mariusz
Published: March 2024

An extensive, high-level theoretical study on tetra-atomic germanium carbide/silicide clusters is presented. Accurate harmonic and anharmonic vibrational frequencies and rotational constants are calculated at the CCSD(T)-F12a(b)/cc-pVT(Q)Z-F12 levels of theory. With growing capabilities to discern more of the chemical composition of the interstellar medium (ISM), an accurate database of reference material is required. The presence of carbon is ubiquitous in the ISM, and silicon is known to be present in interstellar dust grains, however germanium-containing molecules remain elusive. To begin understanding the presence and role of germanium in the ISM, we present this study of the vibrational and rotational spectroscopic properties of various germanium- containing molecules to aid in their potential identification in the ISM with modern observational tools such as the James Webb Space Telescope. Structures studied herein include rhomboidal (r-), diamond (d-), and trapezoidal (t-) tetra-atomic molecules of the form Ge(x)C(4−x) and Ge(x)Si(4−x) , where x=0-4. The most promising structure for detection is r-Ge(2)C(2) via the ν4 mode with a frequency of 802.7 cm−1 (12.5 μm) and an intensity of 307.2 km mol−1. Other molecules potentially detectable, i.e., through vibrational modes or rotational transitions, include r-Ge(3)C, r-GeSi(3), d-GeC(3), r-GeC(3), and t-Ge(2)C(2).

Published: March 2024

We used Random Amplified Polymorphic DNA (RAPD) markers to investigate the genetic structure of two populations of see-see partridge (Ammoperdix griseogularis, Galliformes) from the Suleiman range, in the Pakistani Himalayan region. The see-see partridge is a vulnerable species with a distribution in the Middle East and central Asia. The percentage of polymorphic bands (94.05%), Shannon Index (H = 0.455) and Nei’s average gene diversity (I = 0.298) of A. griseogularis at species level were rather high when compared with other avian species. 17% of polymorphic loci showed statistically significant differences in their allelic frequencies. The G (Nei’s coefficient of genetic variation) values indicated low levels of differentiation (G = 0.08). A genetic distance D of 0.05 indicated that both populations were to some degree in isolation but their differentiation was not significant. Overall, our genetic data can support action plans aiming to locally preserve differentiated genetic resources that, in the future, could potentially result in ecologically and behaviourally differentiated populations. In view of the rapid environmental changes that the Himalayan region has been experiencing in the last decade, this study could help in conservation plans.
Editorial: Bridging the gap between Islamic finance and Sustainable, Responsible, and Impact Investing
Authors: Ghafoor Zeshan
Published: March 2024

In the realm of present-day economics and finance, two significant paradigms, Islamic Finance and Sustainable, Responsible and Impact (SRI) investing, have emerged as strong forces shaping investment ideologies and strategies. Although emerged as distinct fields in global finance, they potentially complement each other. Notably, the financial worth of Islamic Finance is around USD 4.5 trillion globally with an annual growth of 11 to 12 percent, while the financial worth of SRI investing is almost 10 times higher than that of Islamic finance. They have a joint core value proposition that aligns financial decisions with ethical principles while emphasizing a positive impact on society and the environment. Even though their origins and operational structure differ, it is worthwhile to explore the intersection and potential bridges between them.

Published: March 2024

Inflammasomes are immune complexes whose activation leads to the release of pro-inflammatory cytokines IL-18 and IL-1β. Type I IFNs play a role in fighting infection and stimulate the expression of IFN-stimulated genes (ISGs) involved in inflammation. Despite the importance of these cytokines in inflammation, the regulation of inflammasomes by type I IFNs remains poorly understood. Here, we analysed RNA-sequencing data from patients with monogenic interferonopathies and found an up-regulation of several inflammasome-related genes. To investigate the effect of type I IFN on the inflammasome, we treated human monocyte-derived macrophages with IFN-α and observed an increase inCASP1andGSDMDmRNA levels over time, whereasIL1BandNLRP3were not directly correlated to IFN-α exposure time. IFN-α treatment reduced the release of mature IL-1β and IL-18, but not caspase-1, in response to ATP-mediated NLRP3 inflammasome activation, suggesting regulation occurs at cytokine expression levels and not the inflammasome itself. However, more studies are required to investigate how regulation by IFN-α occurs and impacts NLRP3 and other inflammasomes at both transcriptional and post-translational levels.

Authors: Naidu Pridhivraj , Abdul Majid Abdul Halim , Chuah Francis
Published: March 2024

Purpose: Specialist doctors are the indispensable human resource asset of the healthcare industry due to their unique expertise built over time. They are the industry leaders in medical research and play a crucial role in providing specialized care producing better outcomes in overall patients’ treatment. Therefore, the increasing number of specialists leaving government health services has been concerning. In this regard, most research in specialist retention has focused on individual and job factors. However, there is scant research exploring the individual differences that may influence the intention to stay of specialists. Hence, this paper looks to contribute to the literature on specialist doctors’ retention by focusing on the role of equity sensitivity.

Design/Methodology/Approach: The study first establishes the problem of specialist doctors’ retention thru analysis of current reports, secondly investigates the past literature in the constructs relationship and theoretical underpinning to establish the theoretical basis and direction of this study.

Proposition: This paper heeds the limited theoretical precision of social exchange theory highlighted by previous studies to further specify the distinction between hedonically positive and negative values within equity sensitivity construct and in its relations with employee retention.

Implications/Originality/Value: This paper presents the theoretical ambiguity of social exchange theory suggested by prior studies in articulating the bipolarity within equity sensitivity and employee retention research and presents a proposal for the way forward from the challenges in this area of study

Published: March 2024

The aim of the study was to compare the growth rates of various pumpkin (Cucurbita maxima L.) accessions. Pumpkins from Aku I, Aku II, Awka, Ifite-Ogwari Nsukka I, and Nsukka II were the various accessions. A field study was conducted at the Ifite-Ogwari Campus of Nnamdi Azikiwe University in Anambra State. The experiment was laid out using a completely randomized design (CRD) with three replications. As experimental sample units, two (2) of the middle-most plants in each polybag were cut off and tagged. Analysis of Variance (ANOVA) was used to analyze data on vegetative growth factors at a 5% probability level and the treatment means were divided using the least significant difference (LSD 0.05). The result of the experiment revealed that all of the pumpkin accessions performed similarly in terms of the amount of time it took for them to emerge after sowing, their percentage of emergence, and their overall vegetative growth. None of the accessions were statistically different with respect to their emergence and growth parameters. However, the growth parameter evaluations were dominated, on average, by pumpkin accession from Nsukka (I and II) pumpkins. In addition, the Aku II pumpkin had the shortest days-to-emergence (3.33 days) and the greatest mean percentage of emergence (100%). Conversely, Aku I pumpkin consistently performed the lowest when it came to the factors that were looked at. For a comprehensive characterization of C. maxima, additional research at the molecular and genomic levels is advised including a greater number of accessions.

Authors: Pokhrel Saraswata , Neupane Biplab , Chapagain Sujan
Published: March 2024

Farmers in Lamjung have been unable to maximize okra performance and yield due to being unaware of the ideal fertilizer dosage. A field experiment was carried out at Sundarbazar-7, Lamjung during the period from March to June 2023 to understand the optimal N level to enhance the growth and yield of okra. A Randomized Complete Block Design (RCBD) was used to set up the experiment with the seven treatments viz. control, 40, 55, 70, 85, 100, and 115 kg N ha-1 each had three replications. A hybrid variety Arka Anamika mostly used by farmers in Lamjung was used. Recorded data on yield and yield contributing parameters were subjected to statistical analysis and results revealed a significant effect of the treatments on the yield and yield attributes of okra. Plants treated with T6(100 kg N ha-1) had the highest number of fruits per plant (13.10), fruit length (15.84cm), weight of a single pod (15.84 g), and total fruit yield of 14.74 t ha-1. The lowest number of fruits per plant (7.93), fruit length (9.29 cm), single fruit weight (9.29 g), and yield (8.12 t ha-1) were recorded from the control treatment T1 (0 kg N ha-1). Meanwhile, the impact of treatment T6 (100 kg N ha-1) was found to be effective compared to other treatments under study. Based on these findings, the experiment suggests okra farmers to use 100 kg N ha-1 to maximize okra performance and yield considering the soil health.

Authors: Shrestha Bishal , Bhandari Nirajan
Published: March 2024

Poor yield, non-uniform ripening, and delay in maturity are some serious issues faced by commercial banana growers in the country. This research was conducted in a commercial banana orchard of Chitwan from December 2021 to April 2022 in order to study the effect of different doses of ethephon on growth, maturity, and quality of banana. Five different doses of ethephon (200, 400, 600, 800, 1000 ppm) were sprayed on a banana bunch at 15th days after shooting which were compared with the control (no ethephon treatment) in RCBD design.  The maturity of the bunch was significantly hastened at a higher concentration of ethephon (above 600 ppm). Fruit length and fruit weight were also observed higher at 600 ppm (10.21 cm and 62.68 g) and 800 ppm (10.67 cm and 63.26 g) ethephon spray. The bunch treated with 600 ppm ethephon had the highest TSS (10.78oB and 23.27oB at 0 and 5 days of storage, respectively) and PPR (1.65). Considering quantitative and qualitative parameters, preharvest ethephon spray @600 ppm significantly improved growth, maturity, and quality of banana fruits.

The need to develop safe methods for radiation processing of food products to improve their quality and extend their shelf life stimulates new scientific research aimed at increasing their effectiveness. Oxidation of lipids and proteins occurred under the impact of ionizing radiation in products with a high fat and water content, such as chilled meat and fish products, leads to the formation of volatile organic compounds in the product thus giving it a specific smell and taste. During storage, biochemical processes associated with microbial enzymatic activity and auto-oxidation develop in processed refrigerated products. These processes also modify the volatile organic compounds, which affect the organoleptic properties of the product. The method of gas chromatography-mass spectrometry was used to study the behavior of volatile compounds identified in irradiated beef samples both immediately after irradiation and four days later to determine the effective dose range for the radiation processing of beef. Monitoring of the content of volatile compounds in beef samples irradiated by 1-MeV electrons within a dose range from 0.25 to 5 kGy showed that the content of certain alcohols, aldehydes, and alkanes exhibited pronounced dose- and time-dependent character. The developed mathematical model describes the dependence of the concentration of volatile compounds identified immediately after irradiation in beef samples on the irradiation dose. The model is based on the simultaneous occurrence of two competing processes: the decomposition of compounds due to their oxidation and accumulation due to oxidation of other compounds after exposure to ionizing radiation. The results obtained revealed that the effective dosage range of radiation treatment lies between 250 and 1000 Gy.

Tədqiqat işinin məqsədi miokard infarktından sonrakı stenokardiyaların inkişafında immun iltihab reaksiyalarının rolunun müəyyən edilməsi olmuşdur. Bu məqsədlə tədqiqata ürəyin işemik xəstəliyindən (ÜİX) əziyyət çəkən 110 xəstə daxil edilmişdir . Ürəyin işemik xəstəliyi diaqnozu klinik-instrumental müayinələr əsasında verifikasiya olunmuşdur. İmmun iltihab reaksiyalarının immunoferment metodla təyin edilməsi üçün C-reaktiv zülal (C-RZ), proiltihab interleykinlər [İL] - İL-6 və şişlərin nekrozu amilinin (ŞNA-α) səviyyəsi müəyyən edilmişdir.

Nəticə. Postinfarkt stenokardiyalar zamanı İL-6 səviyyəsinin artmasi , ŞNA-α hiperekspressiyası və S-RZ-in yüksək sintezi aşkar olunmuşdur. Sabit stenokardiya zamanı minimal immunoloji dəyişikliklər qeydə alınmışdır. ÜİX-nin destabilizasiyası və eləcə də ifadə olunma dərəcəsi miokard infaktinin agırlaşması ilə bağlı olan immun iltihab reaksiyalarının aktivləşməsi ilə xarakterizə olunur. İmmun iltihab reaksiyalarının qabarıq ifadə olunması miokard infarktının gedişatının proqressivləşməsi ilə assosiasiya olunur.

Təqdim olunmuş məqələdə şəkərli diabet tip 2 və onun metabolik sindromla müştərəkliyi olan xəstələrdə damar sisteminin müxtəlif yataqlarında yerləşən arteriyalarının intima-media kompleksinin qalınlığı və aterosklerotik düyünlərin rastgəlmə tezliyinin öyrəniməsinin nəticələri əks edilmişdir. Göstərilmişdir ki, şəkərli diabet tip 2 və xüsusilə onun metabolik sindromla birlikdə olan pasientlərdə hər iki öyrənilən patolojı göstərici daha tez-tez rast gəlir, bununla da damar sisteminin aterosklerotik prosessinin təsirinə qalmaq meyilliğin sübüt olmuşdur. Hemodinamik əhəmiyyətli aterosklerotik düyünlərinin rastgəlmə tezliyi müqayisə qrupuna nisbətən şəkərli diabet və xüsusilə şəkərli diabet metabolik sindromla yanaşı olan xəstələrdə əsasən geyd edilmişdir. Müqayisə qrupunda intima-media kompleksinin qalınlığının artması və aterosklerotik düyünlərin rastgəlmə tezliyi kişilər arasında daha yüksək olmuşdur, şəkərli diabet və diabet metabolik sindromla birlikdə olan xəstələrdə isə cinslə bağlı əhəmiyyətli fərglər geyd ediməmişdir. Rastgəlmə tezliyinə görə müqaisə olunan gruplarda bəzi fərqlər aşkar olundu. Beləliklə, şəkərli diabet olan xəstələrdə aterosklerotik düyünlər daha tez-tez bud arteriyasında, onun şaxələrində və dizaltı arteriyalarında; şəkərli diabetin metabolik sindromla müştərək olan xəstələrdə- ümumi bud arteriyasında, onun şaxələrində və dizaltı arteriyalarında; şəkərli diabet və metabolik sindrom olmayan xəstələrdə isə- ümumi yuxu arteriyasında, dizaltı və ümumi bud arteriyasında daha yüksək olmuşdur. Müqayisə qrupundan fərq1li olaraq yalnız şəkərli diabet və daha da çox onun metabolik sindromla müştərəkliyi zamanı multifokal aterosklerotik dəyişiklər bir neçə damarın ya da müxtəlif damar yataqlarının pozulması aşkar edilmişdir. Beləliklə, damarlarda aterosklerotik dəyişiklərinin daha tez əmələ gəlməsində, sürətli inkişafında və daha geniş yayılmasında çox əhəmiyyətli ənənəvi faktorlara (yaş, cins, zərərli vərdişlər) üstün gələn risk faktoru hər ikisinin- şəkərli diabetin və metabolik sindromunun- böyük rolu sübut olunmuşdur.

Xroniki perikardial effuziyalar bəzi hallarda önəmli xəstəlik və ölüm səbəbidir. Etiologiyasından asılı olaraq diaqnostik və müalicəvi yanaşma müxtəlifdir. Xüsusilə də xroniki effuziyalarda etioloji amil müalicədə əsas rol oynayır. Bədxassəli şiş mənşəli effuziyalarda perikardiosentez, radioterapiya, o cümlədən təkrarlayan effuziyalarda balon perikardiotomiya uyğun yanaşmadır. Perkutan balon perikardiotomiya – intravenoz sedasiya fonunda kateterizasiya laboratoriyasında aparılan bu müdaxilə şiddətli sinə ağrısı ilə müşayiət olunsada 92% hallarda uğurla nəticələnir 1.
Ürəyin anormal elektrik - keçirici sistemi

Published: March 2024

Ürək avtomatizmi - ürəkdə öz-özünə elektrik impulslarının yaranmasıdır. Bu birinci dərəcəli avtomatizm mərkəzi hesab olunan Sinus düyünunundə (SD) baş verir və atrioventrikular düyündən keçərək His – Purkinye sistemi vasitəsi ilə mədəciklərin yığılmasına səbəb olur. Bu yol ürəyin normal elektrik – keçirici sistemi hesab olunur. SD ürəyin keçirici – elektrik sisteminin əsas generatoru olaraq normada ürəyin 1 dəqiqədə 60 – 100 arasında döyünməsini təmin edir. Digər tərəfdən SD – nün özündə və eləcə də yaxınlığında azan və simpatik sinirlərin lifləri yerləşir və nisbi olaraq onların təsirinə məruz qalır. Lakin, bu sinirlər SD – nü tam təsiri altına ala bilmir. Ürəyin normal elektrik - keçirici sistemi ilə yanaşı, çox nadir hallarda impulsları qısa yolla ötürə bilən (AVD – nu görmədən) digər keçirici – anormal yollar da rast gəlinir. Belə hallarda İmpulslar SD – dən AV düyünə ötürülmədən bilavasitə mədəciklərə çatır və onların erkən oyanmasına – depolyarizasiyasına səbəb olur. Bəzən, belə hallarda qəfləti ölüm müşahidə olunur.

Torasik embriyonik venoz sistemin nadir bir anomaliyası: Sağ superior vena kavanın olmadığı persistan sol superior vena kava
Authors: Səmədli S.Ə.
Published: March 2024

Persistan sol superior vena kava torasik venoz sistemdə ən çox rast gəlinən, ancaq nadir görülən embriyologik bir qalıqdır (ümumi əhalinin 0,3-0,5%-i). Xəstələrin əksəriyyətində normal yerləşən sağ superior vena kava vardır. Birlikdə sağ superior vena kavanın olmaması nadir görülən variantdır (0,07-0,13%). Normal fetal inkişaf prosesi ərzində anterior kardinal venanın obliterasiya olmaması persistan sol superior vena kavaya səbəb olur. Xəstələrin böyük əksəriyyəti simptomsuzdur və diaqnoz görüntüləmə çalışmaları, ya da kardiovaskular proseduralar icra olunarkən təsadüfən qoyulur.Persistan sol superior vena kava santral venoz kateterizasiya, peysmeyker implantasiyası, açıq kardiotorasik əməliyyatlar kimi proseduralarda texniki problemlərə yol aça və komplikasiyaları artıra bilir.

Biz burada transtorasik exokardioqrafiyada genişləmiş koronar sinus görərək şübhələndiyimiz və kontrastlı komputerli tomoqrafiya ilə diaqnozu dəqiqləşdirdiyimiz persistan sol superior vena kava patologiyasının nadir görülən bir variantını təqdim edirik.
