Authors: Huddleston Christina M. , Kloepfer Kirsten M. , Jin Jay J. , Vitalpur Girish V.
Published: September 2020

Food allergy is a growing health and safety concern that affects up to 8% of school-age children. Because children spend a significant part of their day in school, and the overall number of school-age children with food allergy has been increasing, management of food allergies relies
on the collaboration of allergists, families, and schools to treat and prevent acute allergic reactions. For schools, this involves policies centered on food allergen avoidance, preparedness with epinephrine autoinjectors, adequate school personnel training, and accommodations for an equal
opportunity learning environment. Partnerships with allergists, primary care providers, students, families, school nurses, and school staff are vital for creating individualized and effective care plans that will allow all children, including those with food allergies, a safe and nurturing
learning environment.

Authors: Yu Haiyang , Ji Wenjuan , Zheng Jiapeng
Published: September 2020

The dynamic and static gelation process in porous media of the phenol formaldehyde resin gel was studied for successful application in conformance control and water shutoff. Shear rate was the most important factor affecting the dynamic gelation in porous media. Compare to static gelation in ampoule bottles and in porous media, the dynamic gelation time in porous media was extended by 2–6 times. The ability of migration and plugging after dynamic gelation was controlled by system concentration. The porous media permeability was the key factor for dynamic gelling time and strength. The quantitative relationship equation was established between dynamic gelling strength and permeability to choose the appropriate permeability for polymer gel treatment.

Published: September 2020

The motion of nanoparticles near surfaces is of fundamental importance in physics, biology, and chemistry. Liquid cell transmission electron microscopy (LCTEM) is a promising technique for studying motion of nanoparticles with high spatial resolution. Yet, the lack of understanding of how the electron beam of the microscope affects the particle motion has held back advancement in using LCTEM for in situ single nanoparticle and macromolecule tracking at interfaces. Here, we experimentally studied the motion of a model system of gold nanoparticles dispersed in water and moving adjacent to the silicon nitride membrane of a commercial liquid cell in a broad range of electron beam dose rates. We find that the nanoparticles exhibit anomalous diffusive behavior modulated by the electron beam dose rate. We characterized the anomalous diffusion of nanoparticles in LCTEM using a convolutional deep neural network model and canonical statistical tests. The results demonstrate that the nanoparticle motion is governed by fractional Brownian motion at low dose rates, resembling diffusion in a viscoelastic medium, and continuous time random walk at high dose rates, resembling diffusion on an energy landscape with pinning sites. Both behaviors can be explained by the presence of silanol molecular species on the surface of the silicon nitride membrane and the ionic species in solution formed by radiolysis of water in presence of the electron beam.

Published: September 2020

Coronavirus (COVID-19) mediated infection is a highly contagious respiratory illness that was initially found in Wuhan city of Hubei Province in China. The ongoing pandemic of the novel SARS-CoV-2 virus is affecting global health. Despite the recent success in vaccination on a trial basis, there is no treatment of the infection. Thus, establishing an effective therapeutic measure is of apex priority among biologists and healthcare professionals. Re-purposing Remdesivir, a broad-spectrum antiviral agent that inhibits viral RNA polymerase, has been found effective for the treatment of COVID-19. In this study, modification of the existing drug Remdesivir was done. In logical drug designing and development, molecular recognition plays a central role in this sphere. The anti viral function of Remdesivir is achieved by binding to RNA polymerase enzyme. The protein 7BTF is an RNA-dependent RNA polymerase that plays a crucial role in coronavirus replication and transcription machinery and it appears to be the primary target of the antiviral drug Remdesivir. The study intend to design derivative compounds form Remdesivir to screen out the a better drug against the SARS-CoV-2 virus by inhibiting the targeted protein. The efficacy of these new drugs was also tested by molecular docking calculations. The drug derivatives were docked for binding affinity and non-bond interactions. Pharmacokinetic activities of the designed drugs are also predicted. All the drugs are non-carcinogenic and chemically reactive. In our study, modified compound D-I has exhibited the best performance among Remdesivir and it’s derivatives. This study might provide an insight into the potential of a Remdesivir derivative in treating SARS-CoV-2 infection
Biosynthesis of Mycotoxin Fusaric Acid and Application of a PLP-Dependent Enzyme for Chemoenzymatic Synthesis of Substituted L-Pipecolic Acids
Authors: Hai Yang , Chen Mengbin , Huang Arthur , Tang Yi
Published: September 2020

Fusaric acid (FA) is a well-known mycotoxin that plays an important role in plant pathology. The biosynthetic gene cluster for FA has been identified but the biosynthetic pathway remains unclarified. Here, we elucidated the biosynthesis of FA, which features a two-enzyme catalytic cascade, a pyridoxal 5’-phosphate (PLP)-dependent enzyme (Fub7) and a flavin mononucleotide (FMN)-dependent oxidase (Fub9) in synthesizing the picolinic acid scaffold. FA biosynthesis also involves an off-line collaboration between a highly reducing polyketide synthase (HRPKS, Fub1) and a nonribosomal peptide synthetase (NRPS)-like carboxylic acid reductase (Fub8) in making an aliphatic alpha,beta-unsaturated aldehyde. By harnessing the stereoselective C-C bond forming activity of Fub7, we established a chemoenzymatic route for stereoconvergent synthesis of a series of 5-alkyl, 5,5-dialkyl, and 5,5,6-trialkyl-L-pipecolic acids of high diastereomeric ratio.
Identification of a Tambjamine Gene Cluster in Streptomyces Reveals Convergent Evolution of the Biosynthetic Pathway

Published: September 2020

Bacterial natural products are an immensely valuable source of therapeutics. As modern DNA sequencing efforts provide increasing numbers of microbial genomes, it is clear that the molecules produced by most natural product biosynthetic gene clusters (BGCs) remain unknown. Genome mining makes use of bioinformatic techniques to elucidate the natural products produced by these “orphan” BGCs. Here, we report the use of sequence similarity networks (SSNs) and genome neighborhood networks (GNNs) to identify an orphan BGC that is responsible for the production of the antitumor tambjamine BE-18591 in Streptomyces albus NRRL B-2362. Although BE-18591 is a close structural analogue of tambjamine YP1 produced by Pseudoalteromonas tunicata, the biosynthetic routes to produce these molecules differ significantly. Notably, the C12-alkylamine tail that is appended onto the bipyrrole core of tambjamine YP1 is derived from fatty acids siphoned from the primary metabolism of the pseudoalteromonad, whilst the S. albus NRRL B-2362 BGC encodes a dedicated system for the de novo biosynthesis of the alkylamine portion of tambjamine BE-18591. These remarkably different biosynthetic strategies represent a striking example of convergent BGC evolution, with selective pressure for the production of tambjamines seemingly leading to the emergence of separate biosynthetic pathways in pseudoalteromonads and streptomycetes that ultimately produce closely related compounds

Published: September 2020

Mycobacterium ulcerans is the causative agent of Buruli ulcer, a debilitating chronic disease that mainly affects the skin. Current treatments for Buruli ulcer are efficacious, but rely on the use of antibiotics with severe side effects. The enzyme dihydrofolate reductase (DHFR) plays a critical role in the de novo biosynthesis of folate species and is a validated target for several antimicrobials. Here we describe the biochemical and structural characterization of M. ulcerans DHFR and identified P218, a safe antifolate compound in clinical evaluation for malaria, as a potent inhibitor of this enzyme. We expect our results to advance M. ulcerans DHFR as a target for future structure-based drug discovery campaigns.
On the Variability of Ligand pKa during Homogeneously Catalyzed Aqueous Methanol Dehydrogenation
Authors: Govindarajan Nitish , Beks Hugo , Meijer E.J.
Published: September 2020

Using DFT based molecular dynamics simulationsincorporating explicit water solvent, we elucidate the varying behaviour of the ligand pKa of a molecular catalyst for methanol dehydrogenation, using the Ru(PNP) catalytic systemas a case study. The pKa of the amido ligand moiety in this catalytic system is highly sensitive to the species adsorbed on the metalcenter, resulting in a substantial variation of the ligand pKa along the catalytic cycle. Since the ligand pKa is an important characteristic that determines the exact role of the ligand during aqueous methanol dehydrogenation, this characteristic has important implications on metal ligand cooperative pathways.

Kentsel Planlamadaki Değişim ve Dönüşümün Kent Formunun Gelişimine Etkisinin İncelenmesi: Düzce Örneği
Authors: ÖZALP Mehmet Fatih , ARSLAN Hakan
Published: September 2020

Kentler ve kent makroformları dönemsel değişken dinamiklerden etkilenen, form arayış sürecinde sürekli bir değişim içinde olan ve bu değişim sonucunda da kendini sürekli yenileyen ve geliştiren canlı organizmalardır. Bu bağlamda kent formları, dış sınır çizgileri ile kentlerin kültürel, ekonomik ve sosyolojik yapıları hakkında bilgi vermektedirler. Ayrıca kent makroformları kentlerin okuma ve incelenmesinde planlayıcı ve tasarımcılara yardımcı olan bir kavram olarak da karşımıza çıkmaktadırlar. Kentler çevresel (iklim, coğrafya, topoğrafya), fiziksel (kent planlamaları, yapı adası düzenlemeleri, yapılaşma düzeni) ve sosyo-ekonomik (nüfus, kültür, yönetim biçimi) faktörlerin etkisinde kent mekânlarına ve dinamiklerine bağlı olarak çeşitli formlarda gelişme göstererek büyümektedirler. Bu doğal dinamiklere ek olarak kentlerin gelişimini etkileyen diğer bir etken ise deprem, sel, heyelan, kasırga ve tsunami gibi doğal afetlerdir. Kentin gelişimini etkileyen bir doğal afet olarak depremler, kentlerin sadece fiziksel görünümünü etkilemekle kalmayıp aynı zamanda o kentte yaşayan insanların psikososyal yapılarını, kültürlerini, ekonomik durumlarını ve yasayış biçimlerini de etkilemektedirler.
Düzce kentinin hem stratejik bir konumda olması itibariyle hem de 1999 yılında geçirmiş olduğu depremler nedeniyle Düzce kenti ve kent makroformunun tarihsel gelişimi çalışmada incelenecek çalışma alanı olarak belirlenmiştir. Bu çalışmada kentsel değişim ve dönüşüm bağlamında kent makroformunun gelişimi kent planlamalarının tarihsel süreci içerisinde ele alınarak incelenmiştir. Düzce kent makroformu; kentsel gelişimde ve kent formunun şekillenmesinde etkili olan ve belediyenin ilk imar planı olarak bilinen1987 planı, deprem sonrası durumun analiz edilmesine olanak tanıyan 2001 yılına ait plan ve şu an halen kullanılmakta olan 2016 yıllına ait imar planları üzerinden üç dönem şeklinde irdelenmiştir. Çalışmanın materyalleri imar durumları, haritalar ve hava fotoğraflarından oluşmaktadır. Araştırmada kent makroformunun geçirdiği değişim ve dönüşüm süreçlerinin bu materyaller üzerinden incelenmesi ise çalışmanın yöntemini oluşturmaktadır.
Çalışma sonucunda; deprem öncesi, deprem sonrası ve mevut duruma ait üç farklı dönemin imar planları incelenmiş ve kentsel süreçlere bağlı olarak özgün kent formunun ve değişen kentsel dokunun nasıl ortaya çıktığı ortaya konulmuştur. Ayrıca kentin var olan karakterinin, fiziksel ve kültürel formunun oluşum ve değişim dinamikleri belirlenmiştir.

Published: September 2020

Dünya nüfusunun artması ile birlikte atık miktarında da hızlı bir artış meydana gelmektedir. Sürdürülebilir bir çevre, ancak kaynakların korunarak ya da tekrar değerlendirilerek etkili bir şekilde kullanımı ile mümkündür. Atıkların sürdürülebilir bir şekilde tekrar döngüye kazandırılması en etkin yöntemlerden birisi olarak kabul görmektedir. Bu bağlamda, son dönemlerde atıktan enerji elde edilmesi de popüler konular arasındadır. Bu çalışmada, atık araç lastiklerinden piroliz yöntemi ile pirolitik yağlar elde edilmiştir. Bu yağlar, saf dizel yakıtlarla belirli oranlarda harmanlanarak bir dizel motorda kullanılabilirliği test edilmiştir. Testler 250, 500, 750 ve 1000 W motor yüklerinde gerçekleştirilmiştir. Yakıt özelliklerinin iyileştirilmesi amacıyla, dizel-prolitik yakıt karışımlarına daha sonra n-bütanol ilave edilerek karışımın oksijen içeriği zenginleştirilmiştir. Sonuçta, HC ve NO emisyonlarında önemli düşüşler elde edilmiştir. Çalışma, atık araç lastiklerinin tekrar değerlendirilerek saf dizel yakıta göre daha temiz bir şekilde yakılabileceğini ve böylece doğadan yok edilebileceğini göstermektedir. Ayrıca bu çıktılar, sürdürülebilirlik, çevre bilinci, atık yönetimi ve hızla tükenen fosil yakıtlar için de oldukça umut vericidir.
Diversity of boreal small species of Cortinarius subgenus Telamonia with Salix
Authors: Kokkonen Katri
Published: September 2020

This work presents the genetic and morphological diversity of small Cortinarius subgenus Telamonia species found from moist Salix thickets in Finland. The boreal fungi were compared with several type and other specimens from the alpine zone or similar habitats from the temperate zone. The boreal and alpine zones had many common species: nearly all boreal species grew in the alpine zone with dwarf Salix. The species often had wide distributions, extending to North America. The genetic analyses consisted of ITS and RPB2 sequences. Both genetic and morphological variation was high. The species formed complexes, where the boundaries among species were often obscure. Very close sibling species were delimited based on differences at the same sites. Twenty-three boreal species were recognized. Four of them are described here as new: C. paulus and C. paululus as sibling species to C. pauperculus J.Favre, C. rusticelloides as a sibling species to C. rusticellus J.Favre, and C. vienoi as a sibling species to C. perzonatus Reumaux. Cortinarius sagarum, a sibling species to C. comatus J.Favre and C. vulpicolor M.M.Moser & McKnight, is described as new from arctic-alpine zones.

Published: September 2020

Dalam rangka peningkatan peran-peran masyarakat dalam penanggulangan bencana, maka pemerintah Kota Padang memfasilitasi dengan terbentuknya Kelompok Siaga Bencana (KSB). Kecamatan Padang Selatan merupakan salah satu daerah yang melakukan kegiatan pemberdayaan masyarakat, fenomena yang terjadi adalah daerah yang memiliki tingkat kerentanan yang cukup tinggi. Tujuan penelitian ini adalah untuk menjelaskan dan mendeskripsikan proses pemeberdayaan masyarakat dalam pengurangan risiko bencana banjir di Kecamatan Padang Selatan.Berdasarkan dari hasil penelitian, maka dapat di ambil kesimpulan bahwa pemberdayaan masyarakat telah dilakukan oleh BPBD Kota Padang dan KSB Kecamatan Padang Selatan. Akan tetapi, dalam pemberdayaan yang dilakukan belum optimal hal ini disebabkan karena tingkat ketergantungan masyarakat yang tinggi dan tupoksi KSB Kecamatan Padang yang belum jelas dalam melakukan pemberdayaan masyarakat. Adapun saran yang dapat di sampaikan adalah : pelatihan dan sosialisasi dilakukan sebaiknya dilakukan secara merata dan berkelanjutan, serta memperjelas tupoksi KSB agar kegiatan terkait kebencanaan dapat dilakukan dengan semestinya oleh seluruh anggota.

Authors: Scott Samantha , Rivera Kenia , Rushing Ella , Manczak Erika , Rozek Christopher S , Doom Jenalee
Published: September 2020

The COVID-19 pandemic presents unique challenges for adolescents due to disruptions in school and social life. We compiled high schoolers’ open-ended responses to the following question: “What are your 3 biggest challenges right now?” (N=717). Using open and axial coding, we identified N=1902 thematic units (M=2.64, SD=.701) and 14 thematic categories, including mental health, physical health, family, friends, social connection and community, academics, missing important events, socioeconomic, routine, COVID rules and adjustment (e.g., social distancing), contraction/exposure to COVID, technology (e.g., screen time), and future plans. Adolescents most commonly reported challenges related to academics (23.7%), but also cited high numbers of challenges in mental (14.8%) and physical health (13.2%), and friend (11.4%) domains. These findings suggest that efforts should focus on helping adolescents cultivate academic skills needed during school closures, providing mental and physical health resources, and helping adolescents navigate their peer relationships in the short and long-term given ongoing remote education and social distancing due to the pandemic.

In many countries, the COVID-19 pandemic led to a period of lockdown that impacted individual’s lifestyles, in both professional and personal spheres. New problems and challenges arose, as well as opportunities. Numerous studies have examined the negative effects of lockdown measures, but few have attempted to shine light on the potential positive effects that may come out of these measures. We focused on one particular positive outcome that might have emerged from lockdown: creativity. To this end, this paper compared professional creativity (Pro-C) and everyday creativity (little-c) before and during lockdown, using a questionnaire-based study conducted on a French sample (N = 1266). We expected participants to be more creative during than prior to lockdown, in both professional and everyday spheres. Regarding professional creativity, we did not see any significant differences between the two comparison points, before and during lockdown. Regarding everyday creativity, we observed a significant increase during lockdown. Furthermore, our results suggest that participants with a lower baseline creativity (before lockdown) benefited more from the situation than those with a higher initial baseline creativity. Our results provide new insights on the impact of lockdown and its positive outcomes. These measures may have inarguably negative consequences on the physical and mental health of many, but their positive impact exists as well.
Perla: A Conversational Agent for Depression Screening in Digital Ecosystems. Design, Implementation and Validation
Authors: Arrabales Raul
Published: September 2020

Most depression assessment tools are based on self-report questionnaires, such as the Patient Health Questionnaire (PHQ-9). These psychometric instruments can be easily adapted to an online setting by means of electronic forms. However, this approach lacks the interacting and engaging features of modern digital environments. With the aim of making depression screening more available, attractive and effective, we developed Perla, a conversational agent able to perform an interview based on the PHQ-9. We also conducted a validation study in which we compared the results obtained by the traditional self-report questionnaire with Perla’s automated interview. Analyzing the results from this study we draw two significant conclusions: firstly, Perla is much preferred by Internet users, achieving more than 2.5 times more reach than a traditional form-based questionnaire; secondly, her psychometric properties (Cronbach's alpha of 0.81, sensitivity of 96% and specificity of 90%) are excellent and comparable to the traditional well-established depression screening questionnaires.

Effort-Related Decision-Making and its Underlying Processes during Childhood
Toward Curation and Personality-Driven Social Networks
Authors: Bayer Joseph , Hofstra Bas
Published: September 2020

Do humans have bigger or smaller social networks today? We reflect on the state of this research question and assert that an updated approach is needed to understand the effects of emergent technologies on network structure. Although the absolute changes in average network size are likely to remain elusive, recent perspectives converge on the idea that online technologies make it easier for individuals to shape—or curate—their social connections. Here we merge conflicting views and specify mechanisms through which curation technologies may impact personal network structure. Looking forward, we suggest personality will become more influential in network formation and maintenance when aided by technological levers. Consequently, curation technologies have the potential to increase differences in networks between types of people (for example, extroverts vs introverts) and thus generate new forms of social stratification, despite preserving a stable network size on average. The Comment concludes with empirical and theoretical implications, including the importance of attending to dispersion and examining the societal ramifications of personality-driven curation.

The use of digital screens, including television, computers, mobile phones, and smart devices, can be associated with a wide range of health outcomes. During the COVID-19 pandemic, different population groups may have been adapted to varying levels of screen time, which may have profound implications on their health and wellbeing. The available evidence suggests that screen time is associated with obesity, hypertension, type 2 diabetes, myopia, depression, sleep disorders, and many other noncommunicable diseases. This elevated burden of diseases is prevalent among individuals who have sedentary lifestyles and other unhealthy behaviors that are likely to increase during quarantine or isolation due to COVID-19. As several empirical studies have reported a rising trend of screen time during this pandemic, it is critical to assess the adverse health outcomes that may appear as its long-term consequences globally. Researchers and practitioners need to revisit the available guidelines and incorporate evidence-based interventions for preventing unhealthy screen time among the affected individuals. Such interventions may address not only unhealthy screen use behavior but also promote active lifestyles that may improve health across populations during and after this pandemic.
Utility of scatterplot patterns of automated hematology analysers in white blood cell disorders – A comparative study with peripheral blood smears
Authors: Gupta Tavish , Basu Debdatta
Published: September 2020

Background: Advances in automated blood cell counting offer new possibilities to analyse leukocyte differentials by fluorescence RNA/DNA staining combined with scattered light intensity technologies.
Aims and Objectives: The purpose of this study is to identify the scatterplot patterns in normal cell counts and various White Blood Cell (WBC) disorders and to assess their efficacy compared to a peripheral blood smear (PBS) in the diagnosis of WBC disorders.
Materials and Methods: A three-phased descriptive study analysing a total of 933 EDTA blood samples. The total leucocyte count, differential leucocyte count, scatterplot patterns as obtained by automated cell counter and PBS were studied in 405 normal samples (Phase 1) and 415 samples with WBC abnormalities (Phase 2). In phase 3, the scatterplots of 113 abnormal flagged samples were analysed and provisional diagnosis made in each case which was then compared with the diagnosis on the PBS. Sensitivity, Specificity, Positive and Negative predictive values (PPV & NPV) were calculated.
Results: A grid-based standard scatterplot of normal samples was generated as a reference plot in phase one. Based on the scatterplots obtained in known WBC abnormalities studied in phase two, the basic abnormal patterns specific to each of the individual abnormalities were discerned. The phase three study showed excellent correlation between scatterplots and PBS findings in neutrophilia, eosinophilia, lymphocytosis and leukopenia (sensitivity 92-100%, specificity 98-100%). Abnormalities suspected to be leukemia on the scatterplots had a relatively low sensitivity and PPV.
Conclusion: WBC scatterplots can be used as a screening tool as it correlates well with various WBC disorders in the PBS.

Published: September 2020

Background: Vitamin D, a fat-soluble vitamin has its receptor present in myriad of tissues and it modulates multiple cellular processes. Vitamin D deficiency is reported to be associated with coronary artery disease. Cardiovascular disease is the leading cause of mortality worldwide.
Aims and Objective: The primary outcome was to investigate if there is a correlation of 25-OH levels with the percentage of luminal stenosis, as measured with coronary angiogram. The secondary outcome was to determine the differences in angiographically proven luminal stenosis across categories of 25-OH vitamin D levels.
Materials and Methods: Thirty patients with acute coronary syndrome with diabetes mellitus were included in this cross-sectional descriptive study. All patients were tested for fasting vitamin D levels, fasting blood sugar, HbA1C and serum creatinine. Detailed history of the patients was recorded. Data was analyzed by the statistical software SPSS version 19 and p value <0.05 was considered significant. Statistical tests like Chi- square, independent t test and log regression was used.
Results: In this study 30 patients undergoing coronary angiography for acute coronary syndrome, Vitamin D levels showed severe deficiency in 6.7% (2) cases while mild deficiency was seen in 50% of the cases. Patients with single vessel disease on the coronary angiogram had lower mean HbA1C (9.18) levels in our study. Patients with triple vessel disease had poorly controlled mean HbA1C levels (10.42).
Conclusion: In this study we did not find any significant difference between the serum Vitamin D deficiency levels with patients with angiographic severity of the coronary artery disease. Patients with poorly controlled diabetes mellitus had more severe angiographic proven coronary artery disease.
A study of prevalence of microalbuminuria in recently detected type 2 diabetes and its relation to hypertension, dyslipidaemia and obesity
Authors: Acharya Shrikrishna V
Published: September 2020

Background: Microalbuminuria is one of the earliest markers of diabetic nephropathy, and if not recognized and treated early it may lead to diabetic nephropathy resulting in chronic renal failure.
Aims and Objective: The aim of the current study was to find out the prevalence of microalbuminuria among newly detected Type 2 diabetic patients and also compare prevalence of microalbuminuria in patients with or without hypertension, dyslipidaemia and obesity.
Materials and Methods: In this retrospective study, we analysed 90 patients with new onset type 2 diabetes mellitus. We divided the patients into two groups, group 1 with comorbidities like hypertension, dyslipidaemia and obesity (50 patients) and group 2 without comorbidities (40 patients). We analysed urinary microalbumin level in all patients and compared the prevalence of microalbuminuria between group 1 and group 2.
Results: In our cohort of 90 patients, urinary microalbuminuria was found in 30 patients (33.3%). When we divided these nephropathy patients to group1 and group 2, we observed that group 1 with comorbidities had higher percentage of nephropathy patients i.e 24 out of 50(48%). Group 2 with 40 patients had only 6 patients with microalbiminuria ie 6 out of 40(15%). Incidence of microalbiminuria was higher in patients with hypertension, dyslipidaemia and obesity.
Conclusions: We conclude that incidence of microalbiminuria is much more common in newly diagnosed type 2 diabetes. We also conclude that hypertension, obesity and hypercholesterolemia are risk factors for nephropathy and urinary microalbuminuria appears to be much more sensitive than serum creatinine as screening tool to detect diabetic nephropathy.
Embryological and surgical considerations of absent infra-renal part of inferior venacava and left renal vein
Authors: CK Indira , KG Arunkumar
Published: September 2020

Background: Development of inferior vena cava (IVC) is a complex process that involves the anastomoses between three pairs of embryonic veins. Specific permutations exist in the venous plane of the abdomen and pelvis resulting in variations such as single left IVC, double IVC, and left renal retroaortic vein. Anomalies of the inferior vena cava and renal veins occur infrequently but may contribute to serious morbidity throughout surgical exploration if unidentified. Most anomalies remain asymptomatic until surgical intervention or clinical presentation with thromboembolic complications.
Aims and Objective: Our research is aimed to link embryology with developmental disorder and the complications associated with the anomalous vessels in the field of surgery.
Materials and Methods: Ten IUD fetuses (ranging from 20 weeks to term fetuses) were collected from the O&G department of the college and injected locally with dilute formalin and placed in containers filled with formalin. Dissection of the fetuses was done to identify congenital anomalies.
Results: The external appearance of the 28-week-old fetus showed no gross anomaly. Examination abdominal cavity showed absent infrarenal segment of IVC and left renal vein. The right renal vein was seen running a long course to the left side with tributaries of lumbar veins and was seen continuing as the left femoral vein medial to the femoral artery. Segments of suprarenal and renal IVC were present.
Conclusion: Correlating anomalies and variations of IVC and its tributaries to embryology. However, understanding of such anomaly is necessary to avoid significant diagnostic pitfalls and in preoperative surgicaland radiological intervention planning.
