Published: August 2022

Context: The SLC6A4 gene encodes the serotonin transporter. Mutations in this gene can lead to various diseases, such as diabetes. Diabetes is one of the most common metabolic disorders with a genetic background. This review study evaluated the role of SLC6A4 gene polymorphisms in the risk of diabetes. Evidence Acquisition: In this review article, a literature search was conducted in scientific databases, including Google Scholar and PubMed, to find studies published within 2000 to 2021 on the role of SLC6A4 gene polymorphisms on the risk of diabetes. Results: Some genetic and environmental factors are involved in the development of diabetes. Additionally, the association between diabetes and disorder in different genes has been investigated in numerous studies. The discovery of these genetic changes in diabetes might shed light on the functional role of genetic mutations in the development of diabetes. Conclusions: Further genomic research is needed to determine the possible role of SLC6A4 gene polymorphisms in diabetes and obesity.

Authors: Yu Pengcheng , Pan Yeting , Xue Chao , Fang Rui
Published: August 2022

Introduction: Foreign bodies (FBs) in the external auditory canal (EAC) are common in pediatric otorhinolaryngology. Although clinicians have tried many methods and tools to treat these patients, removing the spherical FBs embedded deep in EAC is still a challenge. Occasionally successful removal of such FBs requires local or general anesthesia. Case Presentation: Here, we developed a simple and novel 3-dimensional (3D) printing tool to successfully treat a child suffering from a spherical FB in EAC. The child received no further treatment, and no complications developed afterward. Conclusions: It is challenging to remove spherical FBs in EAC. We developed a tiny, safe, and cheap tool to treat a child with such a FB in EAC. The clinical outcome was satisfactory.

Authors: Soheilipour Fahimeh , Pishgahroudsari Mohadeseh , Pazouki Abdolreza
Published: August 2022

Background: There is little data about the surgical outcomes of different procedures in children. Objectives: We aimed to compare the difference in three-year surgical outcomes between laparoscopic sleeve gastrectomy laparoscopic sleeve gastrectomy (LSG) and one-anastomosis gastric bypass one-anastomosis gastric bypass (OAGB) in children undergoing these procedures. Methods: A total of 96 children aged ≤ 19 years were listed for bariatric surgery to be included in this prospective study. Demographic characteristics, such as age and gender, and anthropometric indices, including height, weight, body mass index, waist circumference, and hip circumference, as well as postoperative complications, were recorded. The participants underwent LSG and OAGB by the same surgical team. The variables were compared between the groups at baseline and 1, 3, 6, 12, 24, and 36 months after surgery. Results: At follow-up, the OAGB group had a higher waist circumference after 1 and 3 month(s) (P = 0.011 and 0.005, respectively) and higher hip circumference 3 months after surgery (P = 0.035). Time significantly affected the trend of changes in weight, body mass index, waist circumference, and hip circumference (P < 0.001). There were no cases of postoperative complications. Conclusions: Our experience showed that LSG had better outcomes after three months, while LSG and OAGB had favorable outcomes on the weight and body mass index (BMI) of children with morbid obesity until three years after surgery.

Published: August 2022

Background: Melanoma is one of the most serious types of skin cancer and one of the leading causes of cancer-related mortality worldwide. Objectives: This study aimed to investigate the association between 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) scan findings and the pathological characteristics of primary tumors in patients with malignant melanoma. Patients and Methods: In this cross-sectional study, the baseline data of 103 patients with cutaneous or mucosal melanoma (stage III or IV) were recorded, and tumor characteristics and PET/CT scan findings were analyzed. The association between each pathological finding and PET/CT results was also investigated. Results: Patients without a free margin had a significantly higher mean standardized uptake value (SUVmax) of lung metastasis compared to patients with a free margin (3.12 vs. 1.69; P = 0.047). Also, patients with ulceration had a significantly higher mean SUVmax of lung metastasis compared to patients without ulceration (3.28 vs. 1.81; P = 0.041). Based on the results, increased primary tumor thickness was associated with a higher SUVmax of lung metastasis. However, there was no significant association between the metastasis type (single vs. multiple) and free margin, ulceration, or Ki-67 protein. The mean SUVmax of lung metastasis was significantly higher in mucosal melanoma compared to cutaneous melanoma. However, the mean SUVmax values of other metastases (bone, liver, and lymph nodes), even the primary lesion itself, were not significantly different between cutaneous melanoma and mucosal melanoma. Conclusion: The primary tumor margin status, ulceration, tumor thickness, primary tumor location (cutaneous vs. mucosal), and the presence of lung metastasis were significantly associated with PET/CT scan findings.

Background: Information literacy is a capability that enables individuals to create, sustain, and deepen communication with others, which can be effective in many organizational dimensions such as organizational ethics and career development. Objectives: This study aimed to determine the relationship of information literacy and professional ethics with career development among Zahedan University of Medical Sciences (ZAUMS) staff. Methods: Using systematic sampling, this cross-sectional study was conducted on 238 ZAUMS staff in southeast Iran in 2018. Data were collected through individual interviews using standard questionnaires Information Literacy, Professional Ethics, and Career Development. The data were analyzed using SPSS-v21 software and descriptive statistics, one-way ANOVA, and t-test. Results: Of 237 individuals, 116 (48.7%) were males with a mean age of 38 years. The information literacy and career development scores were in the moderate range (means of 170 and 56, respectively), while the professional ethics score of the majority was poor, with a mean of 32. There was a significant direct relationship between information literacy (coefficient = 0.189) and professional ethics (coefficient = 0.391) with career development (P < 0.05). Multivariate linear regression showed that an increased level of employees' access to information had significant positive effects on career development (β = 0.878, P < 0.01). Also, an increase in the level of career development (performance evaluation, workplace environment, supervision status, and educational factors) and professional ethics (loyalty and respect to others) was associated with increased levels of information literacy (P < 0.05). Conclusions: Information literacy and professional ethics could increase career development. Therefore, it could improve organizational productivity. It is suggested that professional ethics workshops and courses be held to improve staff's information literacy.

Published: August 2022

In this article, we have introduced a new method that can improve the corrosion resistance of AZ31 alloy. We compared the biodegradation of AZ31 alloy foil treated with a high current density impulse (HCDI), laser irradiation (LI) and HCDI-LI with that of the untreated one. The rate of the biodegradation of AZ31 alloy treated with HCDI-LI was lower than those of the untreated one, the alloy treated with HCDI or LI. Thus, the improved corrosion resistance of the AZ31 alloy treated with HCDI-LI allows its use for medical purposes.

Published: August 2022

Amino acids are one of the main particles in a living organism. They perform many different functions, such as structural, receptor, energetic and enzymatic functions [1]. The aim of the investigation was to identify and evaluate the qualitative composition of free amino acids in samples of Cirsium vulgare material using gas chromatography–mass spectrometry (GC-MS). Our objectives were to apply the gas chromatography– mass spectrometry (GC-MS) method for free amino acids from Cirsium vulgare raw materials grown in Lithuania and determine the qualitative composition of free amino acids from extracts of Cirsium vulgare raw materials: roots, leaves, flowers and seeds. MTBSTFA (N-methyl-N-(tertbutyldimethylsilyl) trifluoroacetamide) was selected for derivatisation in free amino acid analysis. Applying gas chromatography–mass spectrometry with compound derivatisation and based on the mass spectral database free amino acids were identified in bull thistle raw material: L-alanine, glycine, L-valine, L-leucine, L-isoleucine, L-proline, L-serine, L-threonine, L-phenylalanine, L-lysine, L-tyrosine, L-aspartic acid and L-glutamic acid. Studies have shown that the qualitative composition of free amino acids depends on the plant vegetation phase and plant parts.

Published: August 2022

A method for the determination of amizone and amixin in the same sample and in their mixture with antibiotics (ceftriaxone, tetracycline, ampicillin and levofloxacin) was developed using reversed-phase highperformance liquid chromatography equipped with a photodiode array detector. A SunFire C18 column, a mobile phase consisting of sodium perchlorate buffer (pH = 2.5) and acetonitrile (75:25), at a flow rate of 0.8 ml/min, was used. The analytes were identified at 205 and 265 nm. The specificity, linearity, precision parameters, LOD and LOQ were evaluated during the validation of the methodology, and the correlation coefficients of amizone and amixin were 0.9992 and 0.9998, respectively. This method can also be used for the determination of amizone and amixin and their presence in a mixture with antibiotics in the environment.

Published: August 2022

We aimed to demonstrate that breath analysis can be used as a method for the detection of potentially harmful compounds in food after their ingestion. Development of such a method could be adapted as a tool for detection of food intoxication. To achieve this, we compared the levels of pyridine (Py) and furfuryl alcohol (FFA) found in breath with the quantity of these compounds ingested when drinking coffee. Coffee drink beverages were prepared in the laboratory and consumed by volunteers (n = 5). An aliquot of coffee was analysed using high performance liquid chromatography with diode-array detection (HPLC-DAD) to quantify Py and FFA in the beverage. Breath samples were collected several times over a 45 min period after ingestion of coffee and analysed by thermal desorption coupled to gas chromatography/mass spectrometry (TD/GC-MS). The levels of Py and FFA found in coffee ranged from 0.2 to 3 mg/cup of coffee, and from 7 to 30 mg/cup of coffee, respectively. The levels of these compounds detected in breath ranged from 7 to 1200 ng/l breath for Py and from 1 to 760 ng/l breath for FFA. Several parameters can influence the levels of these chemicals in breath, especially the collection time of the breath sample.

An Asymptotic High-Frequency Solution for Scattering from an Electrically Wide Triangular Cavity
Authors: Bozorgi M.
Published: August 2022

An asymptotic solution based on high-frequency approximations is proposed to determine the scattered waves from a wide empty isosceles triangular cavity. The modal method based on cylindrical wavefunction expansion with the physical optics technique is used to find analytical expressions for the unknown expansion coefficients and significantly improve the time efficiency of calculations. Some assumptions and simplifications are made to reduce the complexity of the problem while still being accurate for wide triangular cavities. Comparisons are achieved to illustrate the validity and time efficiency of the suggested solution.

Authors: Tiwari Priyadarshini , Diwar Seema
Published: August 2022

Introduction: Management of critically ill obstetric population admitted to Intensive Care Unit (ICU) remains a significant hurdle in developing countries. Aim: To examine demographic characteristics, diagnoses, clinical outcomes, and performance of modified Sequential Organ Failure Assessment (SOFA) score between survivors and non survivors in all obstetric admissions to the ICU. Materials and Methods: This was a longitudinal study conducted in a 12-bedded obstetric ICU at 850 bedded Netaji Subhash Chandra Bose Medical College, Madhya Pradesh, India from March 2016 to August 2017. Clinical profile and outcomes of ICU patients were analysed for total 367 obstetric ICU admission. To determine mortality outcomes of the study population, a modified SOFA score was used to take into account physiological changes in pregnancy. All statistical analyses were performed using Statistical Package for Social Sciences (SPSS) version 15.0 (Inc., Chicago, Illinois, USA). Receiver Operating Characteristics (ROC) curve analyses of SOFA score as a predictor of mortality, and optimum cutoff point value was determined. Results: The mean age of the study population was 24.7±4.0 years. Eclampsia (35.7%) and preeclampsia (13.62%) were the leading indications of admission. The survival of patients was associated significantly with low SOFA scores with mean SOFA score of 6.48±2.804 among survivors and 10.42±3.579 among non survivors (p-value=0.001). Conclusion: Eclampsia and preeclampsia were the leading cause of ICU admission, that can be preventable. Higher SOFA score was related to higher mortality in the obstetric patients requiring ICU.

Published: August 2022

Introduction: Surgical Site Infections (SSIs) remain a significant postoperative complication after abdominal surgeries, even with the advancement of infection control practices. The emergence of drug resistance to routine antibiotics was a challenge to infected wound management. Aim: To analyse the host risk factors and bacterial flora associated with abdominal surgical site infections and to evaluate the changes in the prevalence and antibiotic susceptibility pattern over the years. Materials and Methods: A cross-sectional study was done among 150 abdominal surgery cases admitted to a Government Medical College Thrissur, (referral hospital) in Kerala, India for one year, from September 2010 to August 2011. Host risk factors were analysed by clinical details and preoperative investigations. Samples were collected from the wound site on the third day of surgery using sterile swabs for bacteriological analysis. Repeated samples were taken in case of suspected wound infection to identify the types of pathogen if any. Statistical analysis was done using Microsoft excel and open Epi software. The results were compared with the similar studies conducted in this institution during 2015-2016 and 2016-2017 to know the changes in prevalence and antimicrobial sensitivity. Result: Out of 150 cases higher infection rate was found in patients >60 years 5 (17.2%), emergency surgeries 16 (21.6%), large intestinal surgeries 4 (44.4%), with diabetes 5 (26.32%), patients on steroids and obese 3 (37.5%). Colonisers were present in 34.7% abdominal surgical wounds. Infection rate of 14.7% in abdominal surgeries was reduced to 11.2% and 10% between the years 2015-16 and 2016-17 respectively. Higher infection rate was noticed in patients with premorbid risk factors. When compared with the similar studies conducted in the same institute, Pseudomonas and Acinetobacter with E. coli and S. aureus were found to be most common wound pathogens and resistance to ciprofloxacin and ceftriaxone were increased. Amikacin, piperacillin tazobactam and imipenem were useful but decreasing in sensitivity were noticed. Conclusion: Bacterial colonisation with endogenous flora was the primary source of SSIs. Good infection control practices, early identification of the pathogen and treatment with an appropriate antibiotics can reduce the development of resistant organisms and cross infection. The use of antimicrobials for prophylaxis and treatment needed to be modified according to the antimicrobial sensitivity report and local susceptibility pattern.

Introduction: Thrombocytopenia is now a day’s common haematological finding with various aetiologies is the situation where there is low blood platelet count. Aetiology for thrombocytopenia is multi factorial which makes the management challenging. Aim: To study the clinicopathological spectrum of thrombocytopenia in population of Sangli district, Maharashtra, India. Materials and Methods: A cross-sectional study was conducted in a tertiary care centre in Sangli district, Maharashtra, India, for a period of two years from July 2019 to June 2021. It included 920 patients with platelet count<1.5 lakh/mm3 irrespective of their age group. The clinical profile laboratory data and complications of patients with a platelet count of less than 1,50,000/mm3 were analysed and tabulated. All the collected data was tabulated in MS-Excel and analysed in Statistical Package for the Social Sciences (SPSS) version 20.0 where frequency distribution was used test study variables. Results: The total sample size was 920 with 546 (59.35%) males and 374 (40.65%) females. Out of 920 patients, majority 392 (42.61%) were diagnosed with infections that lead to thrombocytopenia where dengue was identified as the most common cause having 173 (18.80%) cases followed by other infection and other diseases. Conclusion: Dengue was observed to be the most common infectious disease causing thrombocytopenia in this study. The present study might help in categorising the level of infection i.e., mild or severe thrombocytopenia. Early signs of bleeding could stop further complications and transformation into high risk towards different morbidities respectively.

A Copula-Based Approach for Modelling the Dependence between Inflation and Exchange Rate in Kenya
Authors: Tracy Kaneza , Waititu Helen , Sewe Stanley
Published: August 2022

In this study, we modeled the dependence structure between inflation and exchange rate using the copula approach. To formulate a bivariate copula, we used ARMA+GARCH to model serial dependence for each univariate series of returns. Both for in ation and exchange rate, it was found that the student t distribution was the best marginal distribution. Then, we transformed the standardized residuals from those marginal distributions (student t) into uniform over the range [0; 1]. To estimate the copula, we used a parametric approach. Gumbel copula was found to be the best to capture the dependence. We investigated the time-varying dependence using change-point detection based on copula. We found that there is a significant change in the nature of dependence over the period under consideration. The change in the nature of dependence between the two variables was in line with the prevailing macro-economics conditions during the period under review. We recommend to the future researchers to consider studying time-varying dependence between those two variables and investigate also the change in copula parameters in values with time. We also recommend including other macroeconomic variables while modeling the relationship between in ation and exchange rate.

Published: August 2022

The present study was conducted during the year 2021-22 by following Ex-Post-Facto research design with objective of studying the perception and utilization of services of RBKs among the farmers of western blocks of Chittoor district, India. The foremost constraint expressed by farmers were dearth of timely sourcing of quality inputs and services it might be due to meager performance of RBK in the study area/quite few number of farmers aware of the activities carried out by the RBK. Very few (<5%) of the farmers have perception and utilization towards organic certification, availing organic inputs like neem cake, vermicompost, neem oil, natural farming products, IPM kits, biofertilizers and bio-fungicides the plausible reason might be that implementation of Farmer Field School programme for creating awareness about the scientific methods of agricultural production and to achieve higher agricultural income at lower cost on cluster basis by RBKs and provision of IPM kits and organic inputs to those cluster farmers might have resulted in lesser perception and utilization.

Curry leaf being perishable commodity and is mostly subjected to excessive post-harvest losses and quantity deterioration in a short span of time. Pre-harvest management system can minimize the losses of curry leaf and by enhancing the shelf life. Thus the present research was conducted to evaluate the effect of chemical spray on shelf life extension and quality of curry leaf. The experimental treatments were comprised of three chemicals (salicylic acid, sodium carbonate and ascorbic acid) at different concentration and the total number of treatments were ten and replicated thrice following completely randomized design (CRD). The results revealed that pre-harvest application of salicylic acid (SA) @ 100 ppm retains the freshness of curry leaf with extended shelf life without any deterioration in quality. On comparison between treatments, salicylic acid @ 100 ppm delayed physiological loss in weight (25.19%), retained chlorophyll content (1.195 mg/g) and ascorbic acid content (3.510 mg/100g). This was followed by ascorbic acid (AA) @ 100 ppm which prevented the degradation of beta-carotene in curry leaf upto seven days of storage at ambient condition. GC-MS analysis of bioactive compounds extracted from essential oil of curry leaf confirmed the presence of limonene compound in salicylic acid treated sample which is related with extending the shelf life. Hence individual and combined effect of  SA @ 100 ppm followed by AA @ 100 ppm considered to be the best pre-harvest treatment for enhancing shelf life and maintaining the quality of curry leaf.

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are very common “over-the-counter” commonly abused drugs used in treating fever, pain and inflammatory conditions. They inhibit prostaglandins and can cause kidney disease and hypertension, particularly in stressed states like dehydration and exercises.

Objectives: To access prescription pattern and effects of common NSAIDs on the kidneys.

Methods: One hundred frequent NSAIDs users (daily use > 4 weeks) and 100 healthy controls, who had no known risk factor for kidney disease and gave consent were recruited. Blood samples for serum electrolytes, urea and creatinine, haemoglobin concentration and urine samples for dip strip, and 24 hour protein were collected and analysed.

Results: The mean age of the controls, all NSAIDs users, NSAIDs users without kidney dysfunction (KD) and NSAIDs users with KD were 46.04 + 14.21 years, 46.5 + 14.2 years, 41.84 years + 14.52 yrs and 63.04 + 4.21 years respectively, P=0.03. The mean estimated glomerular filtration rate (eGFR) was significantly lower in frequent NSAIDs users than controls, P<0.001. Ibuprofen was the most nephrotoxic and, nephrotoxicity was positively related to combination therapy (P<0.001) and duration of use (P=0.03). Herbal medicines significantly increased the risk of KD, P=0.01. Predictors of KD were advancing age, longer duration of NSAIDs use, Ibuprofen use and combined NSAIDs.

Conclusion: Frequent NSAIDs use, common in Orthopaedic units, could be complicated by kidney dysfunction. Ibuprofen, followed by ketoprofen, was the most nephrotoxic. Observed risk factors for NSAIDs induced nephrotoxicity included advancing age, herbal remedies, Ibuprofen and combination therapy.

The impact of hypertension as being the leading cause of death in industrialized societies pressed the importance of low-cost and accessible therapeutic agents present in food sources. This study was undertaken to evaluate the in-vitro Angiotensin-converting Enzyme (ACE) inhibitory activity of flavonoid-rich Onion and Shallot bulb extracts. Ethyl acetate, Butanol and Aqueous fractions of onion and shallot bulb extracts at varying concentrations were obtained through purification by solvent extraction. Positive control was the prototype ACE-inhibitor, Captopril. ACE-inhibitory activity was determined using the ACE-kit commercially manufactured by Dojindo, Inc. (Japan). All fractions of onion and shallot bulb extracts exhibited greater than 50% inhibitory activity towards ACE.  The aqueous fractions of both bulbs showed the highest ACE-inhibitory activity exceeding the flavonoid standard, Quercetin, and were comparable with the prototype ACE-I, Captopril.

Based on the study findings, onion and shallot bulbs can be potential sources of bioactive compounds that can inhibit the activity of ACE which can be used to provide a natural, perhaps safer, cost-effective alternative in reducing blood pressure.

Aims: To describe a Neovascular Glaucoma Secondary to Bloch-Sulzberger Syndrome.

Presentation of Case: A.B.F. female, 23 years old, claimed significant pain sensation and hyperemia in the left eye (LE) for 45 days, without triggering factors. She came to the consultation with a previous diagnosis of Bloch-Sulzberger Syndrome with pigmented lesions in the lower limbs since childhood, being followed up by dermatology since then.

Discussion: The diagnosis of IP (Incontinentia Pigmenti) is complex because it mimics other dermatoses. The impairment in other systems, such as the ophthalmic system, with the possibility of loss of vision and functional disability is a reality. The natural history of retinal lesions is not fully understood. Vascular changes seem to start in the first weeks of life and progress after birth for weeks or months, and may stabilize at any stage, leaving numerous sequelae.

Conclusions: Incontinentia pigmenti is difficult to diagnose and, at each evolutionary stage, presents many differential diagnoses. Eye injuries can lead to blindness as a consequence of ischemic events that can start soon after birth.
The impact of COVID‐19 workflow changes on radiation oncology incident reporting
Authors: Volpini Matthew E. , Lekx‐Toniolo Katie , Mahon Robert , Buckley Lesley
Published: August 2022

Background

The Ottawa Hospital's Radiation Oncology program maintains the Incident Learning System (ILS)—a quality assurance program that consists of report submissions of errors and near misses arising from all major domains of radiation. In March 2020, the department adopted workflow changes to optimize patient and provider safety during the COVID‐19 pandemic.

Purpose

In this study, we analyzed the number and type of ILS submissions pre‐ and postpandemic precautions to assess the impact of COVID‐19‐related workflow changes.

Methods

ILS data was collected over six one‐year time periods between March 2016 and March 2021. For all time periods, the number of ILS submissions were counted. Each ILS submission was analyzed for the specific treatment domain from which it arose and its root cause, explaining the impetus for the error or near miss.

Results

Since the onset of COVID‐19‐related workflow changes, the total number of ILS submissions have reduced by approximately 25%. Similarly, there were 30% fewer ILS submissions per number of treatment courses compared to prepandemic data. There was also an increase in the proportion of “treatment planning” ILS submissions and a 50% reduction in the proportion of “decision to treat” ILS submissions compared to previous years. Root cause analysis revealed there were more incidents attributable to “poor, incomplete, or unclear documentation” during the pandemic year.

Conclusions

COVID‐19 workflow changes were associated with fewer ILS submissions, but a relative increase in submissions stemming from poor documentation and communication. It is imperative to analyze ILS submission data, particularly in a changing work environment, as it highlights the potential and realized mistakes that impact patient and staff safety.

Although myelitis is the second most common presentation in adults with myelin oligodendrocyte glycoprotein (MOG) antibody‐associated disease (MOGAD), studies on MOG‐IgG seroprevalence in patients with myelitis episodes are sparse. Herein, we investigated MOG‐IgG seroprevalence in Korean adults who exhibited myelitis since 2017. Among 151 adults with acute myelitis, 11 (7.3%) tested positive for MOG‐IgG by the initial screening and 10 (6.6%) patients were finally diagnosed with MOGAD during the study period. This study is the first to provide data on MOG‐IgG seroprevalence in adults with myelitis and supports the clinical utility and importance of MOG‐IgG testing in myelitis episodes.

Published: August 2022

Lattice structures are known for their superior performance in weight reduction, stiffness, and increased manufacturability, but when materials need to be adaptive, multifunctional, and with tunable properties, functionally graded lattice structures (FGLS) play a crucial role in innovative solutions. Recent digital manufacturing technologies offer ideal conditions for creating lattice structures with high geometrical complexity and functional gradients. However, the design and development of these inherently complex structures often require the use of specialized methods and software tools. As researchers venture from diverse areas into the research of FGLS in search of novel applications, it is important to choose adequate design tools. Herein, an overview of methods and software for the design of FGLS is presented, identifying geometrical parameters of common lattice topologies and ways to manipulate them to create functional gradients. Fifty software applications or methods are listed, dedicated to the design of single material lattices produced by additive manufacturing processes. Typical applications of the reviewed software are identified, and FGLS design methods are compared. Generative Design seems more suited as an explorative process, Topology Optimization is an established efficiency‐focused design process, and Machine Learning is considered a promising data‐driven approach for the design of innovative FGLS.

Published: August 2022

Laser cladding of superalloys provides an attractive and cost‐efficient technique for near‐net shape manufacturing, remanufacturing, or individualized repair of components. While the weldability of γ' hardened Ni‐base superalloys is limited, Co‐base superalloys should have a lower susceptibility for cracking during welding due to a lower γ' solvus temperature and less segregation than Ni‐base superalloys. The weldability of the Co‐base superalloy CoWAlloy2Mod and the resulting mechanical properties at 950 °C are investigated. In the as‐welded condition of CoWAlloy2Mod, a fine dendritic microstructure without forming cracks and limited porosity is found. After a three‐step heat treatment, recrystallized, equiaxed grains and a high γ' volume fraction are obtained leading to a very good strength. CoWAlloy2Mod shows a significantly higher strength and creep strength than the conventional weld filler Co‐alloy PWA795.
