Risk Topics Discovery and Trend Analysis in Air Traffic Control Operations—Air Traffic Control Incident Reports from 2000 to 2022
Authors: Liu Wenquan , Zhang Honghai , Shi Zongbei , Wang Yufei , Chang Jing , Zhang Jinpeng
Published: August 2023

The safety of air traffic control (ATC) operations is an important cornerstone for the sustainable development of the civil aviation industry. In order to clarify the risk factors in the control operation process and to achieve digital representation of the safety risks of civil aviation control operations, starting from the ATC incident reports, we fully mine the safety risk information and unspoken rules of ATC operations. A risk perception model for air traffic control operations safety based on the Latent Dirichlet Allocation (LDA) topic model and the Semantic Network Based on BERT (BSN) model is suggested. First, 17 risk topics and keywords were found in the incident reports collected using the LDA topic model. These topics included those pertaining to the stage of aircraft operation, human factors in control operation, and the sector or airspace operation status and structure. The findings indicate that while most risk subjects have not changed significantly, they do show an upward tendency. Human factors and operational rules and procedures account for the highest share of all key causes, and they also have a significant impact on how risk topics evolve over time. Finally, the BSN model in the air traffic control field was built based on the keywords of each risk issue in order to highlight any potential correlations between distinct risk topics. The results show that some risk topics have interrelated risk characteristics, and there are regularities of mutual evolution between these risk topics. The relevant research results can better mine air traffic control unsafe information and lay a foundation for accurately perceiving air traffic control operations risks.

Authors: Frangioudakis Khatib Georgia , Collins Julia , Otness Pierina , Goode James , Tomley Stacey , Franklin Peter , Ross Justine
Published: August 2023

Asbestos remains ubiquitous in the Australian built environment. Of the 13 million tonnes of asbestos products installed in earlier decades, an estimated 50% remain in situ today. Because of the extensive past use of asbestos, and the increasing age of these products, the potential for exposure to asbestos fibres in both indoor and outdoor environments remains high, even while the actual asbestos exposure levels are mostly very low. Sources of these exposures include disturbance of in situ asbestos-containing materials (ACMs), for example during renovations or following disaster events such as fires, cyclones and floods. Our understanding of the risk of asbestos-related disease arising from long-term low-level or background exposure, however, is poor. We provide the most up-to-date review of asbestos exposure risks currently affecting different groups of the Australian population and the settings in which this can manifest. From this, a need for low-level asbestos monitoring has emerged, and further research is required to address whether current exposure monitoring approaches are adequate. In addition, we make the case for proactive asbestos removal to reduce the risk of ongoing asbestos contamination and exposure due to deteriorating, disturbed or damaged ACMs, while improving long-term building sustainability, as well as the sustainability of limited resources.

Authors: Ngongoni Chipo Nancy , Wasswa William , Chibi Moredreck
Published: August 2023

The COVID-19 pandemic led to a global surge of health care innovations aimed at curbing the pandemic. Some of the innovations were newly developed whereas others were modifications of existing technologies to suit the COVID-19 response. With the world achieving some level of normalcy, the question is what will become of these innovations. This study reviewed and analysed 1003 innovations that were utilised for the COVID-19 response to assess if they are still being utilised to strengthen health systems. The paper goes on to identify, profile and showcase 48 innovations and trace their evolution to support and strengthen Primary Health Care. Through this analysis and narration, four strategic pillars of collaboration, governance, innovation design and strategy emerge as factors that help explain the successful integration of these innovations in Primary Health Care. Under these pillars emerged nine key aspects of strategic inter-industry collaborations, standardisation and supportive policies, minimalistic and modular designs, off-grid capabilities, interoperability, data infrastructure, interoperability, data analytics including security and privacy, and the design of technology around ecosystems and platforms. The overall aim of this study is to inform the dynamics around the improvement of scaling and increase the sustainability of innovations across the African region to strengthen health systems and promote innovation.
Evaluation of Sustainable Slope Stability with Anti-Slide Piles Using an Integrated AHP-VIKOR Methodology
Authors: Tuskan Yesim , Basari Ender
Published: August 2023

The sustainable design of major civil engineering projects, such as landslide management and slope stability, provides new opportunities for our society regarding the global energy crisis. These sources offer an effective solution to environmental issues and human energy needs. Slope stability, as a critical aspect of ensuring public safety and protection of infrastructure, often leads to disastrous consequences, highlighting the significance of designing effective and sustainable measures to mitigate the risks associated with landslides. Although anti-slide piles have become a widely used method to enhance slope stability, this paper investigates how the Analytic Hierarchy Process (AHP) and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methodologies can be combined to achieve a sustainable design for anti-slide piles, simultaneously considering environmental, economic, safety, and technical factors. Through the integration of AHP-VIKOR and a case study, this paper demonstrates an effective approach to prioritizing sustainability in the design process of anti-slide pile systems, evaluating five main criteria—slope stability, sustainability, anti-slide pile capacity, cost, and ease of construction—and five sub-criteria. The proposed methodology is validated through a case study, wherein various design alternatives for anti-slide piles are evaluated based on sustainable requirements. The results indicate that the slope stability criterion has the highest weight of 0.404, followed by anti-slide pile capacity (0.283), sustainability (0.129), and cost (0.146) criteria. The ease of construction has the lowest weight of 0.038. As a result of the evaluations, it has been seen that, if the sustainability criteria are included in the analyses, the anti-slide pile alternatives are determined in the range of ξ = 0.1–0.3 and s/D = 2.0–3.0, compared to the scenarios where only the economic and technical criteria are satisfied. A pile geometry of diameter, D = 1.00 m, is the most sustainable value within the selected pile spacing intervals, meeting the criteria of slope safety, pile capacity, cost, and ease of construction. This hybrid approach allows for a more balanced consideration of a multi-criteria decision, while considering the sustainability aspects of anti-slide pile selection.

Published: August 2023

Hepatotoxic microcystins (MCs) are produced and released by the harmful bloom-forming cyanobacteria, which severely threaten drinking water safety and human health due to their high toxicity, widespread distribution, and structural stability. The linearized microcystinase (MlrB) further hydrolyses the poisonous linearized MCs produced by the microcystinase-catalysed MCs to form tetrapeptides. Here, the purification and activity of MlrB were investigated. The results showed that the linearized products generated by 12.5 mg/L MC-LR and MC-RR were removed by purified recombinant MlrB at a protein concentration of 1 mg/L within 30 min. The high catalytic activity of MlrB can be obtained via heterologous expression and affinity purification, which lays the foundation for further studies on the properties and mechanism of MCs biodegradation enzymes.

Published: August 2023

Alternaria mycotoxins are a class of important, agriculture-related hazardous materials, and their contamination in ruminant feeds and products might bring severe toxic effects to animals and even human beings. To control these hazardous compounds, a reliable and sensitive LC-MS/MS (liquid chromatography–tandem mass spectrometry) method was established for simultaneous determination of six target Alternaria mycotoxins in ruminant feeds, including ALT (Altenuene), AME (Alternariol Monomethyl Ether), AOH (Alternariol), ATX-Ι (Altertoxins I), TeA (Tenuazonic Acid), and TEN (Tentoxin). This developed analytical method was used for the determination of the presence of these substances in cattle and sheep feeds in Xinjiang Province, China. The results revealed that Alternaria mycotoxins are ubiquitously detected in feed samples. Especially, AME, AOH, TeA, and TEN are the most frequently found mycotoxins with a positive rate over 40% and a concentration range of 4~551 µg/kg. The proposed method could be applied for exposure investigation of Alternaria mycotoxins in ruminant feeds and for the reduction in the health risk to animals and even consumers.

Toxoplasma gondii is deemed a successful parasite worldwide with a wide range of hosts. Currently, a combination of pyrimethamine and sulfadiazine serves as the first-line treatment; however, these drugs have serious adverse effects. Therefore, it is imperative to focus on new therapies that produce the desired effect with the lowest possible dose. The designation and synthesis of sulfonamide-1,2,3-triazole hybrids (3a–c) were performed to create hybrid frameworks. The newly synthesized compounds were loaded on chitosan nanoparticles (CNPs) to form nanoformulations (3a.CNP, 3b.CNP, 3c.CNP) for further in vitro investigation as an anti-Toxoplasma treatment. The current study demonstrated that all examined compounds were active against T. gondii in vitro relative to the control drug, sulfadiazine. 3c.CNP showed the best impact against T. gondii with the lowest IC50 value of 3.64 µg/mL. Using light microscopy, it was found that Vero cells treated with the three nanoformulae showed remarkable morphological improvement, and tachyzoites were rarely seen in the treated cells. Moreover, scanning and transmission electron microscopic studies confirmed the efficacy of the prepared nanoformulae on the parasites. All of them caused parasite ultrastructural damage and altered morphology, suggesting a cytopathic effect and hence confirming their promising anti-Toxoplasma activity.

Published: August 2023

Forests are critical water supply regions that are increasingly threatened by natural and anthropogenic disturbance. Evaluation of runoff-generating processes within harvested and undisturbed headwater catchments provides insight into disturbance impacts on water quality and drinking water treatability. In this study, an extensive hydrologic dataset collected at the experimental Turkey Lakes Watershed (TLW) located on the Canadian Shield was used to quantify sources of stormflow in legacy clear-cut (24-years post harvesting) and forested (control) headwater catchments using an end member mixing analysis (EMMA) model. Stream water, groundwater, soil water, and throughfall water quality were evaluated during spring snowmelt, stormflow, and fall wet-up. Groundwater chemistry was similar to stream water chemistry in both catchments, suggesting that groundwater is a major contributor to stream flow. The water chemistry in small wetlands within the study catchments was comparable to stream water chemistry, suggesting that wetlands are also important contributors to stream flow. Differences in wetland position between the legacy clear-cut and control catchments appeared to have a greater influence on source contributions than legacy harvesting. Results from this study provide insight into runoff-generation processes that reflect event/seasonal flow dynamics and the impacts on water quality.
Innovative Urban Blue Space Design in a Changing Climate: Transition Models in the Baltic Sea Region
Authors: Burda Izabela Maria , Nyka Lucyna
Published: August 2023

Waterfront areas in cities are subject to constant changes. The desire to integrate the transformed waterside areas with the urban fabric involves shaping high-quality public spaces related to water, which are often referred to as urban blue spaces (UBS). The aim of the research was to examine the transformation processes of urban waterfront areas in the Baltic Sea Region and identify emerging transition models and types of blue public spaces. The methodological framework of this study is based on qualitative analysis of urban form with respect to coastal and riverine waters. An introductory analysis of 50 cases of transformations was conducted, and 12 were selected for further investigation: Tallinn, Pärnu (Estonia), Copenhagen, Køge, Aarhus (Denmark), Helsinki, Turku (Finland), Stockholm, Malmö, Luleå, Sundsvall, and Ystad (Sweden). As the outcome of the study, the authors indicate that the existing hard land–water interfaces were transformed into soft transition zones where new types of blue public spaces were created with different relationships to water. Synergies were identified between public space design, flood protection measures, and climate adaptation schemes. Finally, the findings highlight the need to verify the existing planning regulations and make them more flexible and effective in guiding the sustainable waterfront design processes.

Published: August 2023

Huge amounts of fresh water are used in the concrete industry every day. The quantity and quality of water play important roles in determining the quality, strength, setting time, and durability of cement-based materials (CBMs), such as paste, mortar, and concrete. Freshwater systems are under pressure due to climate changes, industrialisation, population growth, urbanisation, and the lack of proper water resource management. The lack of potable water has resulted in the search for possible alternatives, such as seawater, treated industrial wastewater, treated sewage wastewater, carwash service station wastewater, wastewater from ready-mix concrete plants, and wastewater from the stone-cutting industry. All of these water resources can be used in concrete to achieve adequate industry standards for the physical and chemical characteristics of concrete. This study is a comprehensive review of the existing information regarding the effects of alternate water resources on the fresh, physical, strength, and durability properties of CBMs. The review shows that the research on the utilisation of wastewater in CBMs is limited. The development of different procedures and methods is urgently needed to utilise various wastewaters in concrete production. The usage of various wastewaters in concrete construction overcomes their adverse impacts on the environment and human health.
The burden of acute eye conditions on different healthcare providers: a retrospective population-based study
Authors: Rawlings Anna , Hobby Angharad E , Ryan Barbara , Carson-Stevens Andrew , North Rachel , Smith Mathew , Gwyn Sioned , Sheen Nik , Acton Jennifer H
Published: August 2023

Background

The demand for acute eyecare exponentially outstrips capacity. The public lacks awareness of community eyecare services.

Aim

To quantify the burden of acute eyecare on different healthcare service providers in a national population through prescribing and medicines provision by GPs, optometrists, and pharmacists, and provision of care by accident and emergency (A&E) services. A secondary aim was to characterise some of the drivers of this burden.

Design and setting

A retrospective data-linkage study set in Wales, UK.

Method

Analysis of datasets was undertaken from the Secure Anonymised Information Linkage Databank (GP and A&E), the Eye Health Examination Wales service (optometry), and the Common Ailments Scheme (pharmacy) during 2017–2018.

Results

A total of 173 999 acute eyecare episodes delivered by GPs (168 877 episodes) and A&E services (5122) were identified during the study. This resulted in 65.4 episodes of care per 1000 people per year. GPs prescribed a total of 87 973 653 prescriptions within the general population. Of these, 820 693 were related to acute eyecare, resulting in a prescribing rate of 0.9%. A total of 5122 eye-related and 905 224 general A&E attendances were identified, respectively, resulting in an A&E attendance rate of 0.6%. Optometrists and pharmacists managed 51.8% (116 868) and 0.6% (2635) of all episodes, respectively. Older females and infants of both sexes were more likely to use GP prescribing services, while adolescent and middle-aged males were more likely to visit A&E. GP prescribing burden was driven partially by economic deprivation, access to services, and health score. Season, day of the week, and time of day were predictors of burden in GP and A&E.

Conclusion

Acute eyecare continues to place considerable burden on GP and A&E services in Wales, particularly in urban areas with greater economic deprivation and lower overall health. This is likely to increase with a rapidly ageing population. With ongoing pathway development to better utilise optometry and pharmacy, and improved public awareness, there may be scope to change this trajectory.

Marine organisms perform a sea of diel rhythmicity. Planktonic diel dynamics have been shown to be driven by light, energy resources, circadian rhythms, and the coordinated coupling of photoautotrophs and heterotrophic bacterioplankton. Here, we explore the diel fluctuation of viral production and decay and their impact on the total and active bacterial community in the coastal and open seawaters of the South China Sea. The results showed that the night-production diel pattern of lytic viral production was concurrent with the lower viral decay at night, contributing to the accumulation of the viral population size during the night for surface waters. The diel variations in bacterial activity, community composition, and diversity were found highly affected by viral dynamics. This was revealed by the finding that bacterial community diversity was positively correlated to lytic viral production in the euphotic zone of the open ocean but was negatively related to lysogenic viral production in the coastal ocean. Such distinct but contrasting correlations suggest that viral life strategies can not only contribute to diversifying bacterial community but also potentially piggyback their host to dominate bacterial community, suggesting the tightly synchronized depth-dependent and habitat-specific diel patterns of virus–host interactions. It further implies that viruses serve as an ecologically important driver of bacterial diel dynamics across the ocean, highlighting the viral roles in bacterial ecological and biogeochemical processes in the ocean.

Published: August 2023

The death of children under-five years is one of the critical issues in public health and the need for improving child survival continues to be a matter of urgent concern. In this study, we develop a predictive model in order to examine the risk factors of under-five mortality in Nigeria. The study utilized data from 2018 Nigeria Demographic and Health survey. The demographic and mortality data of 127,545 children were extracted and univariate and multivariate logistic regression models were employed. The results revealed that under-five mortality was 143 deaths per 1,000 live births in Nigeria. The likelihood of death was higher among males compared to females children (OR = 1.893, P<0.05). First and second birth order have a lower chances of decreasing odds of under-five children (OR = 0.737, P<0.05) and (OR = 1.888, P<0.05).The under-five mortality was higher among children born to mothers who belong to other religions compared to Christians. Islam (OR = 1.689, P<0.05) and traditionalist (OR = 2.705, P<0.05) respectively. Public servant (OR = 1.881, P<0.05) and unmarried mother (OR = 1.896, P<0.05) were increased the odds of dying chances of under-five mortality in Nigeria. Children of mothers without education experienced more death compared to mothers who attended post-secondary education (OR = 3.372, P<0.05). Sex of child, birth order, religion, marital status, maternal occupation and maternal education were significant factors associated with under-five mortality in Nigeria. Thus, planning and implementing relevant strategies that focus on those identified risks factors of under-five mortality is required for improvement of child survival in Nigeria.

Flood disasters can occur at any time when the factors for the amount of river water discharge and rainfall intensity tend to be high, so preparations and ways of handling are needed to anticipate flood disasters quickly, precisely, and accurately for the Surabaya Public Works Service. One of the steps to predict and analyze the status of the flood disaster alert level is by calculating predictions based on rainfall and the amount of river water discharge. This study uses the Long-Short Term Memory (LSTM) algorithm to predict rainfall and river water discharge on the Jagir River in Surabaya. The LSTM method is a model commonly used for predictions based on time series data. The data obtained are rainfall data and water discharge on the Jagir River, Surabaya, which will be used as training and testing data to make predictions. The results of implementing the LSTM method using data training of 70% and data testing of 30% on rainfall data using the best epoch, namely at epoch ten by producing tests on data testing can have a Mean Absolute Error (MAE) performance of 4.5 and Root Mean Square Error (RMSE) of 9.7. Whereas the water discharge variable uses the best epoch, namely at epoch 75, by producing data testing data which can have a Mean Absolute Error (MAE) performance of 11.49 and a Root Mean Square Error (RMSE) of 9.63.

One of the little-studied and promising ways to increase the yield of crops is the use of nanoparticles, especially of the biological origin. Recently, research has been carried out in this direction, however, there is still very little information and it is unambiguous. In this regard, the purpose of this study was to obtain silver nanoparticles (AgNPs) with use of Pseudomonas stutzeri and Bacillus sp. bacteria, which expressed high biosynthetic activity, and to determine their effect on the germination of wheat seeds. The culture liquids containing AgNPs were used to treat wheat seeds (Unumli bugdoy variety). The treated seeds were placed in Petri dishes with moistened filter paper to germinate during 7 days. The received AgNPs were characterized by UV spectroscopy and AFM. It was determined that strains of Pseudomonas stutzeri and Bacillus sp. possess the ability to synthesize oval and spherical AgNPs ranging in size from 5 to 100 nm. It was revealed that the treatment of wheat seeds with a cultural liquid containing biogenic AgNPs stimulated seeds’ germination, and also had a stimulating effect on the growth of roots and stems of plants, the accumulation of the dry matter mass of the roots and the aerial part of the seedlings.

Authors: Erdirençelebi Dilek , Yiğit Recep
Published: August 2023

Biomethanation and dewaterability characteristics of primary sludge (PS), secondary sludge (SS) and mixed sludge (MS) fractions were assessed after anaerobic stabilization under parallel batch and continuous mixing conditions at 35℃ in order to investigate the performance of the separate digestion system. Similar methane conversion/yield values were obtained in PS, SS and MS digestion with continuous mixing’s positive effect only in PS digestion. Continuous mixing resulted in 50% increase in the methane yield (600(+/-100) mL/g VSadd.d. SS digestion produced a comparable methane yield at 650(+/-100) mL/g VSadd.d showing no effect due to mixing pattern. Settling and dewaterability characteristics of the stabilized PS were superior to stabilized SS samples. A reverse relationship was obtained between settling and dewaterability characteristics where intermittent mixing enhanced settling ability while continuous mixing resulted in higher dewaterability of the stabilized sludges. Polyelectrolyte (PE) addition showed a negative effect on the settleability of the sludges. Low degree mixing resulted in 50% sludge volume reduction and an SVI of 64 mL/g VS compared to 25% volume reduction and 82 mL/g SVI in the continuous mixing mode for the stabilized PS. A similar trend for the stabilized SS but weaker values with 25% volume reduction and an SVI 182 mL/g in the intermittent mixing mode compared to 15% volume reduction and 200 mL/g VS SVI indicated a much lower settleability in the continuous mixing mode and compared to stabilized PS.

Authors:   Korea Trade Research Association, Lee Da-Sol
Published: August 2023

Purpose – Although the importance and necessity of “sustainable supply chain management (SCM)” is emphasized, it is often not realized due to conflicting results, the long time required, and large-scale changes brought about by sustainability. This study used the innovation resistance model to confirm the influence of sustainable SCM innovation resistance factors and dynamic capabilities on adoption intentions. This approach made it possible to understand the factors that hinder adoption of sustainability practices and to identify the relationships among influencing factors. It should also help to establish effective policies or strategies. Design/methodology – Through a literature review, the characteristics of sustainable SCM were classified into relative advantage, compatibility, perceived risk, and complexity. The effects of these innovation characteristics on innovation resistance in sustainable SCM and the effects of innovation resistance on adoption intentions were confirmed. In addition, the effects of SCM capabilities on innovation resistance and adoption intentions were analyzed, and the mediating effect of innovation resistance was analyzed. Findings – Compatibility, perceived risk, and flexibility had significant effects on innovation resistance. In turn, innovation resistance had a significant effect on adoption intention, and flexibility had a significant effect on intention to adopt. A partial mediating effect of resistance to innovation was confirmed. Originality/value – Although many previous studies have acknowledged trade-offs with sustainability, most sustainable SCM studies dealt with the correlations among positive drivers of adoption, practices, and performance. This study confirmed the process of accepting sustainable SCM innovation in a single model and is expected to serve as a cornerstone for future sustainable SCM adoption studies. In addition, our findings should help establish effective policies or strategies to activate SSCM adoption by identifying the factors that hinder the adoption of sustainable SCM.

Introduction: The educational process is one of the leading factors determining health of schoolchildren. Identification of pathologic afflictions among students can contribute to targeted development of health promotion activities and significantly reduce risks of diseases related to learning.
Objective: To compare prevalence rates in elementary, secondary and high school students.
Materials and methods: In January 2021 to October 2022, 498 schoolchildren passed comprehensive medical examinations. They were subdivided into three cohorts: cohort 1 consisted of 132 elementary school students (median age = 8 (7; 9) years), cohort 2 included 257 secondary school students (13 (11; 14) years), and cohort 3 comprised 109
high school students aged 16 (16; 17) years. The prevalence was assessed based on doctors’ statements; the data and statistics were analyzed using Jamovi.
Results: Diseases of the musculoskeletal and digestive systems and endocrine disorders were found to be the most prevalent among the students (68.9–87.5 per 100 examined). The highest fold difference was established between high and elementary school students for the prevalence rates of tension-type headache (32.1), chronic gastritis and duodenitis (22.9), myopia (5.1), and scoliosis (2.9). We observed a direct relationship between educational stages and the development of those diseases.
Conclusions: Our findings indicate the need of including additional examinations by neurologists and otolaryngologists at different ages in the procedure for conducting health checkups of minors. The focus, content and scope of health promotion, disease prevention, and outreach activities of pediatricians and preventive medicine physicians should be determined taking into account age-specific prevalence rates and the established association between stages of school education and certain health disorders.

Introduction: The number of mental and behavioral disorders in juvenile convicts tends to increase and worsen, since this contingent often has a burdened heredity and is prone to development of chronic diseases, and is also committed to the abuse of psychoactive substances.
Objective: To study mental health and mental characteristics of minor convicts incarcerated in juvenile corrections of the Federal Penitentiary Service of Russia based on long-term data of statistical analysis and psychological testing.
Materials and methods: We used forms of departmental statistical observation to study mental health of juvenile convicts. Psychological characteristics of 122 juvenile male convicts aged 15–17 years were assessed in 2021 using the Eysenck Personality Questionnaire and Leonhard–Shmishek Test and then compared with those observed in a similar age and sex group of adolescents. To establish specifics of the incidence in the juvenile convicts, we also compared their disease rates with those registered and sex-adjusted in teenagers aged 15–17 years. We calculated extensive and intensive indicators, 95 % confidence intervals, and statistical significance of differences using the t-tests and the χ-square test.
Results: The incidence of mental and behavioral disorders in juvenile convicts incarcerated in juvenile corrections was 10.9 times higher than the standardized incidence in 15 to 17-year-old adolescents (14,050.6 ± 3,881.3 and 1,290.4 ± 427.9, respectively; p < 0.01). We established a low proportion of melancholics (2.9 % (95 % CI: 0.9–7.2), p < 0.05) and the predominance of stable types of temperament in those convicts.
Conclusions: The incidence of mental and behavioral disorders in juvenile convicts incarcerated in juvenile corrections is 11 times higher than the sex-standardized incidence in their 15 to 17-year-old peers. Hyperthymic and excitable types of personality accentuation prevail in them with a pronounced tendency to stable types of temperament.

Authors: Hamouda Tamer , Omran Tarek , Shaalan Ayman
Published: August 2023

Background: Minimal invasive valve surgery is the new trend in cardiac surgery. Many obstacles are present to increase the number of cases operated on with minimally invasive surgery. Minimal invasive surgery is technically demanding in obese patients with uncertain outcomes. In this study, we compared minimal invasive mitral and tricuspid valve surgery (MIVS) in obese patients with high BMI (body mass index) to normal BMI.

Method: We included 240 cases who underwent MIVS. These cases were divided into two groups. Group I (n=120) included patients with BMI >30 Kg/m2, and Group II (n=120) had BMI ≤30 Kg/m2.

Result: There was no in-hospital mortality in both group. Postoperative wound infection was nonsignificantly higher in Group I (9 (7.5%) vs. 2 (1.67%); P= 0.059). Drainage (450± 112 vs. 240± 230 ml; P<0.001), mechanical ventilation time (13.4± 1.3 vs. 6.4± 6.8 h; P<0.001), and ICU stay (2± 0.4 vs. 3.5± 1.3 days, P<0.001) were significantly higher in Group I. New onset atrial fibrillation was significantly higher in obese patients (P= 0.029). There were no differences between both groups in other outcomes.

Conclusion: Minimally invasive surgery in obese patients had satisfactory outcomes compared to those with normal BMI. Obesity should not be considered a contraindication for minimally invasive surgery.
Timing of repair of ischemic ventricular septal rupture; results of early vs. late repair
Authors: Fouly Mohamed , Mousa Tarek
Published: August 2023

Background: The optimal time to repair ischemic ventricular septal rupture (VSR) is debatable. We compared the outcomes, including operative mortality, between patients who underwent early vs. late VSR repair.

Methods: Twenty-eight patients presented with VSR were included in this study. Patients were grouped according to the timing of repair into two groups; the early repair group (n= 12) and the late repair group (n= 16). The primary endpoint was operative mortality.

Results: There was no difference in age, gender, and associated comorbidities between between early and late repair. Anteroapical VSR was the most common type in both groups. There was no difference in the number of bypass grafts in both groups. Ischemic (95 (88- 142.5) vs. 137 (120- 147.5) min; P= 0.028) and cardiopulmonary bypass times (123.5 (115.5- 177.5) vs. 172.5 (152.5- 185) min; P= 0.023) were significantly shorter in patients who had delayed repair. Nine patients (75%) had operative mortality in the early repair group versus three patients (18.75%) in the late repair group (P= 0.006). There were no differences in blood loss, stroke, wound infection, ICU, and ward stay among the surviving patients.

Conclusion: Delayed repair of ischemic ventricular septal rupture could be associated with lower mortality in properly selected patients. Additionally, the delayed repair could decrease the ischemic and cardiopulmonary bypass times.

Published: August 2023

Background: Minimally invasive mitral valve surgery (MIMVS) is associated with less surgical trauma. However, its advantages over the conventional approach are controversial. This study aims to compare the early postoperative pain, hospital stay, and pulmonary function between minimally invasive and conventional mitral repair.

Methods: Fifty patients with non-ischemic mitral valve disease who had mitral valve repair between 2017 and 2019 were included in the study. Patients were randomly divided into two equal groups. Group A (n=25) included patients who had minimally invasive mitral valve repair via anterolateral mini-thoracotomy with video assistance, and Group B (n=25) included patients who had mitral valve repair via median sternotomy.

Results: The cross-clamp (99.45±16.01 vs. 87. 5±19.16 min; p= 0.058) and the total bypass times (134.08±27.38 vs. 120.71±22.18 min; p= 0.35) were nonsignificantly longer in Group A. Operative time was significantly longer in Group A (207.08±44.31 vs. 173.54±28.25 min; p= 0.001). The ICU stay in Group (A) was 2.58±1.44 days, and in Group (B), the ICU stay was 3.75±1.77 days (p= 0.001). The hospital stay was 7.87±1.59 days in Group A, and 14.5 ±5.05 days in Group B (P<0.001). Postoperative FEV1 was  2.06±0.63 L in Group A and 1.39±0.43 L in Group B (p= 0.001). There was no difference in postoperative ejection fraction between both groups (p= 0.9).

Conclusion: Minimal invasive mitral valve repair could reduce postoperative pain, length of ICU, and hospital stay and improve the postoperative respiratory function when compared to the conventional approach.
