Overactive bladder negatively affects erectile function and promotes premature ejaculation: findings from large representative population-level study.

PURPOSE: The effect of overactive bladder (OAB) on sexual health has been evaluated extensively for women but much less for men. Therefore, the aim of this study was to evaluate the relationship between OAB and men's sexual activity and the effect of OAB on erectile dysfunction (ED) and premature ejaculation (PE) in a large representative cohort of men at the population level. METHODS: This study was based on computer-assisted web interviews that used validated questionnaires. The most recent census and the sample size estimation calculations were employed to produce a population-representative pool. RESULTS: The study included 3001 men, representative of the population in terms of age and place of residence. The frequency of sexual intercourse was higher for respondents without OAB symptoms compared with persons who had OAB (p = 0.001), but there was no association between OAB symptoms and number of sexual partners (p = 0.754). Regression models did not confirm the effect of OAB on sexual activity (odds ratio 0.993, CI 0.974-1.013, p = 0.511). Both ED and PE were more prevalent in respondents with OAB symptoms compared with persons who lacked those symptoms (p < 0.001). Importantly, the effect of OAB on ED or PE was independent of age, comorbidities, and lifestyle habits (regression coefficients of 0.13 and 0.158 for ED and PE, respectively). CONCLUSION: Overactive bladder did not significantly affect men's sexual activity, but it significantly correlated with ED and PE. Our results suggest a need in daily clinical practice to screen for OAB symptoms for persons who report ED or PE.

Extracellular vesicles from the mycoparasitic fungus Trichoderma harzianum.

Trichoderma harzianum is a filamentous fungus that can act as a mycoparasite, saprophyte, or a plant symbiotic. It is widely used as a biological control agent against phytopathogenic fungi and can also be used for plant growth promotion and biofortification. Interaction between T. harzianum and phytopathogenic fungi involves mycoparasitism, competition, and antibiosis. Extracellular vesicles (EVs) have been described as presenting a central role in mechanisms of communication and interaction among fungus and their hosts. In this study, we characterized extracellular vesicles of T. harzianum produced during growth in the presence of glucose or S. sclerotiorum mycelia. A set of vesicular proteins was identified using proteomic approach, mainly presenting predicted signal peptides.

Gender representation at scientific congresses: focus on functional and female urology-a study from the EAU Young Academic Urologist Functional Urology Group.

PURPOSE: Female representation at scientific conferences is crucial for encouraging women pursuing an academic career. Nevertheless, gender inequity at urological conferences is common place and women are often stereotyped choosing functional urology. However, there is no evidence whether female representation is higher in functional urology. This investigations aims to analyze gender representation at functional urology sessions. METHODS: National and international urological congresses between 2019 and 2021 with a focus on functional urology and female urology sessions were evaluated. Congresses were categorized as national or international. Session type, topic, gender of chairs and speakers of the identified sessions were recorded. In addition, affiliation and medical specialty were collected for chairs. RESULTS: A total of 29 congresses were evaluated. Out of a total of 2893 chairs and speakers, 1034 (35.7%) were women and 1839 (63.6%) were men. This represents an overall gender gap of 27.9% for functional urology sessions. No significant differences in gender representation between national and international congresses could be identified (p = 0.076). When considering gender distribution of chairs, the gap was more pronounced by 35.5%. Furthermore, men were more likely to be invited to be a speaker in plenary and podiums sessions. CONCLUSIONS: Gender inequality is present in functional urology sessions. There is a need for greater efforts to achieve gender equality. An important step to remedy the situation is the inclusion of women in scientific program committees. Furthermore, support by the leadership of urological societies and academic departments is essential to herald a lasting change in gender inequality.

Development of Neurogenic Detrusor Overactivity after Thoracic Spinal Cord Injury Is Accompanied by Time-Dependent Changes in Lumbosacral Expression of Axonal Growth Regulators.

Thoracic spinal cord injury (SCI) results in urinary dysfunction, which majorly affects the quality of life of SCI patients. Abnormal sprouting of lumbosacral bladder afferents plays a crucial role in this condition. Underlying mechanisms may include changes in expression of regulators of axonal growth, including chondroitin sulphate proteoglycans (CSPGs), myelin-associated inhibitors (MAIs) and repulsive guidance molecules, known to be upregulated at the injury site post SCI. Here, we confirmed lumbosacral upregulation of the growth-associated protein GAP43 in SCI animals with bladder dysfunction, indicating the occurrence of axonal sprouting. Neurocan and Phosphacan (CSPGs), as well as Nogo-A (MAI), at the same spinal segments were upregulated 7 days post injury (dpi) but returned to baseline values 28 dpi. In turn, qPCR analysis of the mRNA levels for receptors of those repulsive molecules in dorsal root ganglia (DRG) neurons showed a time-dependent decrease in receptor expression. In vitro assays with DRG neurons from SCI rats demonstrated that exposure to high levels of NGF downregulated the expression of some, but not all, receptors for those regulators of axonal growth. The present results, therefore, show significant molecular changes at the lumbosacral cord and DRGs after thoracic lesion, likely critically involved in neuroplastic events leading to urinary impairment.

Prognostic Factors in Penile Cancer: Should We Avoid Inguinal Lymph Node Staging?

INTRODUCTION: Penile cancer (PC) is a rare neoplasm, mostly in developed countries. Herewith, we evaluate the main prognostic factors of patients with PC undergoing surgery. METHODS: This is a retrospective analysis of prognostic factors of overall survival in 65 patients with PC treated at a tertiary referral center over the last 15 years (2004-2018). RESULTS: Almost half (48%) of the patients were diagnosed at an advanced local stage pT3/4. Thirty-eight (58%) patients underwent inguinal lymphadenectomy, and 25 (66%) were negative for lymph node (LN) invasion. Overall survival was 80% at a median follow-up of 31 months. In the multivariate analysis, the main factors of poor prognosis were nodal staging (pN) (p = 0.008) and perineural invasion (p = 0.023). The presence of LN metastasis and perineural invasion in the primary tumor increased the risk of death by 29 (hazard ratio 29.0, 95% confidence interval 2.4-354.2) and 13 (hazard ratio 12.7, 95% confidence interval 1.4-112.0) times, respectively. DISCUSSION/CONCLUSION: Late diagnosis of PC has a negative impact on overall survival, as nodal invasion correlates with survival. Despite the high number of negative inguinal lymphadenectomy, we continue to advocate aggressive surgical treatment of this disease due to the poor prognosis associated with LN metastasis.

Top-down characterization of endogenous protein complexes with native proteomics.

Protein complexes exhibit great diversity in protein membership, post-translational modifications and noncovalent cofactors, enabling them to function as the actuators of many important biological processes. The exposition of these molecular features using current methods lacks either throughput or molecular specificity, ultimately limiting the use of protein complexes as direct analytical targets in a wide range of applications. Here, we apply native proteomics, enabled by a multistage tandem MS approach, to characterize 125 intact endogenous complexes and 217 distinct proteoforms derived from mouse heart and human cancer cell lines in discovery mode. The native conditions preserved soluble protein-protein interactions, high-stoichiometry noncovalent cofactors, covalent modifications to cysteines, and, remarkably, superoxide ligands bound to the metal cofactor of superoxide dismutase 2. These data enable precise compositional analysis of protein complexes as they exist in the cell and demonstrate a new approach that uses MS as a bridge to structural biology.

Improving Intraoperative Communication in Trauma: The Educational Effect of the Joint DSTC™-DATC™ Courses.

BACKGROUND: Operative management of severe trauma requires excellent communication among team members. The surgeon and anesthesiologist need to interact efficiently, exchanging vital information. The Definitive Surgical Trauma Care (DSTC) and Definitive Anesthesia Trauma Care (DATC) courses provide an excellent opportunity for teamwork training. Our goal was to study the impact of the joint DSTC-DATC courses in candidates' self-reported assessment in communication skills and techniques in a simulated intraoperative trauma scenario. METHODS: Study population consists of 93 candidates (67 surgeons and 26 anesthesiologists) participating in four consecutive joint DSTC-DATC courses in May and June 2019 in Brazil (3) and in Portugal (1). Median age was 30 years; 53 (60%) of subjects were male (46 senior residents and 47 specialists). All participants attended joint lectures, case discussions and surgical skills session, emphasizing intraoperative communication. Post-course survey on several aspects of perioperative communication (responses on a Likert scale) was conducted with participants being asked which aspects of intraoperative communication they valued the most. RESULTS: All participants responded to the survey. Results displayed an increase in the self-assessed importance of team briefing and intraoperative communication, particularly routine periodic communication, rather than only at critical moments. Postoperative team debriefing was also valued as highly relevant. Closed-loop and direct, by-name communication were highly rated. Self-reported communication skills improved significantly during the course. CONCLUSIONS: Joint training in the DSTC-DATC courses improved candidates' perception and skills on proficient intraoperative communication. Further studies should address both the durability of these changes and the potential impact on patient care.

An informatic framework for decoding protein complexes by top-down mass spectrometry.

Efforts to map the human protein interactome have resulted in information about thousands of multi-protein assemblies housed in public repositories, but the molecular characterization and stoichiometry of their protein subunits remains largely unknown. Here, we report a computational search strategy that supports hierarchical top-down analysis for precise identification and scoring of multi-proteoform complexes by native mass spectrometry.

Characterizing the Structure and Oligomerization of Major Royal Jelly Protein 1 (MRJP1) by Mass Spectrometry and Complementary Biophysical Tools.

Royal jelly (RJ) triggers the development of female honeybee larvae into queens. This effect has been attributed to the presence of major royal jelly protein 1 (MRJP1) in RJ. MRJP1 isolated from royal jelly is tightly associated with apisimin, a 54-residue α-helical peptide that promotes the noncovalent assembly of MRJP1 into multimers. No high-resolution structural data are available for these complexes, and their binding stoichiometry remains uncertain. We examined MRJP1/apisimin using a range of biophysical techniques. We also investigated the behavior of deglycosylated samples, as well as samples with reduced apisimin content. Our mass spectrometry (MS) data demonstrate that the native complexes predominantly exist in a (MRJP14 apisimin4) stoichiometry. Hydrogen/deuterium exchange MS reveals that MRJP1 within these complexes is extensively disordered in the range of residues 20-265. Marginally stable secondary structure (likely antiparallel ß-sheet) exists around residues 266-432. These weakly structured regions interchange with conformers that are extensively unfolded, giving rise to bimodal (EX1) isotope distributions. We propose that the native complexes have a "dimer of dimers" quaternary structure in which MRJP1 chains are bridged by apisimin. Specifically, our data suggest that apisimin acts as a linker that forms hydrophobic contacts involving the MRJP1 segment 316VLFFGLV322. Deglycosylation produces large soluble aggregates, highlighting the role of glycans as aggregation inhibitors. Samples with reduced apisimin content form dimeric complexes with a (MRJP12 apisimin1) stoichiometry. The information uncovered in this work will help pave the way toward a better understanding of the unique physiological role played by MRJP1 during queen differentiation.

Native GELFrEE: a new separation technique for biomolecular assemblies.

The cadre of protein complexes in cells performs an array of functions necessary for life. Their varied structures are foundational to their ability to perform biological functions, lending great import to the elucidation of complex composition and dynamics. Native separation techniques that are operative on low sample amounts and provide high resolution are necessary to gain valuable data on endogenous complexes. Here, we detail and optimize the use of tube gel separations to produce samples proven compatible with native, multistage mass spectrometry (nMS/MS). We find that a continuous system (i.e., no stacking gel) with a gradient in its extent of cross-linking and use of the clear native buffer system performs well for both fractionation and native mass spectrometry of heart extracts and a fungal secretome. This integrated advance in separations and nMS/MS offers the prospect of untargeted proteomics at the next hierarchical level of protein organization in biology.

Secretomic survey of Trichoderma harzianum grown on plant biomass substrates.

The present work aims at characterizing T. harzianum secretome when the fungus is grown in synthetic medium supplemented with one of the four substrates: glucose, cellulose, xylan, and sugarcane bagasse (SB). The characterization was done by enzymatic assays and proteomic analysis using 2-DE/MALDI-TOF and gel-free shotgun LC-MS/MS. The results showed that SB induced the highest cellulolytic and xylanolytic activities when compared with the other substrates, while remarkable differences in terms of number and distribution of protein spots in 2-DE gels were also observed among the samples. Additionally, treatment of the secretomes with PNGase F revealed that most spot trails in 2-DE gels corresponded to N-glycosylated proteoforms. The LC-MS/MS analysis of the samples identified 626 different protein groups, including carbohydrate-active enzymes and accessory, noncatalytic, and cell-wall-associated proteins. Although the SB-induced secretome displayed the highest cellulolytic and xylanolytic activities, it did not correspond to a higher proteome complexity because CM-cellulose-induced secretome was significantly more diverse. Among the identified proteins, 73% were exclusive to one condition, while only 5% were present in all samples. Therefore, this study disclosed the variation of T. harzianum secretome in response to different substrates and revealed the diversity of the fungus enzymatic toolbox.

Impaired resolution of inflammation in human chronic heart failure.

BACKGROUND: Lipoxins (LXs) are proresolving and anti-inflammatory eicosanoids whose role in chronic heart failure (CHF) pathogenesis has never been investigated. This study evaluated levels of LXs in CHF patients, its relationship with disease severity and correlation with established CHF biomarkers. The effect of low-dose aspirin [acetylsalicylic acid (ASA)] on the levels of LXs was also studied. MATERIALS AND METHODS: Lipoxin A4 (LXA4 ), 15-epi-lipoxin A4 (15-epi-LXA4 ) and myeloperoxidase (MPO) concentration and activity were evaluated by immunoenzymatic and spectrophotometric assays in 34 CHF patients [New York Heart Association (NYHA) functional class I to IV]. B-type natriuretic peptide (BNP), troponin, myoglobin, C-reactive protein (CRP) and uric acid (UA) were also analyzed. RESULTS: Patients were stratified into mild-to-moderate CHF (NYHA, classes I and II) and severe CHF (NYHA classes III and IV). Severe patients had lower plasma LXA4 (0·262 ± 0·034 vs. 0·362 ± 0·039 ng/mL, P < 0·05) and decreased urinary 15-epi-LXA4 levels (2·28 ± 0·44 vs. 4·88 ± 1·03 µg/day, P < 0·05) besides exhibiting increased plasma BNP (1464 ± 442 vs. 555 ± 162 pg/mL, P < 0·05) and MPO activity (45·15 ± 11·56 vs. 15·90 ± 2·80 µmol/min/mg protein, P < 0·05). Plasma LXA4 was inversely correlated with BNP, troponin, myoglobin, CRP, UA and MPO activity. ASA treatment was associated with higher urinary excretion of 15-epi-LXA4 (7·70 ± 1·48 vs. 2·06 ± 0·30 µg/day, P < 0·05) in mild-to-moderate CHF patients and lower BNP levels in both groups. CONCLUSIONS: Higher severity of CHF is associated with reduced levels of LXs. Plasma LXA4 appears to be a valuable marker for risk stratification in CHF. Furthermore, the ASA-related increase in urinary 15-epi-LXA4 suggests enhanced renal synthesis of this eicosanoid and may represent a disregarded benefit of ASA.

A sex-associated sequence identified by RAPD screening in gynogenetic individuals of turbot (Scophthalmus maximus).

Understanding the genetic basis of sex determination mechanisms is essential for improving the productivity of farmed aquaculture fish species like turbot (Scophthalmus maximus). In culture conditions turbot males grow slower than females starting from eight months post-hatch, and this differential growth rate is maintained until sexual maturation is reached, being mature females almost twice as big as males of the same age. The goal of this study was to identify sex-specific DNA markers in turbot using comparative random amplified polymorphism DNA (RAPD) profiles in males and females to get new insights of the genetic architecture related to sex determination. In order to do this, we analyzed 540 commercial 10-mer RAPD primers in male and female pools of a gynogenetic family because of its higher inbreeding, which facilitates the detection of associations across the genome. Two sex-linked RAPD markers were identified in the female pool and one in the male pool. After the analysis of the three markers on individual samples of each pool and also in unrelated individuals, only one RAPD showed significant association with females. This marker was isolated, cloned and sequenced, containing two sequences, a microsatellite (SEX01) and a minisatellite (SEX02), which were mapped in the turbot reference map. From this map position, through a comparative mapping approach, we identified Foxl2, a relevant gene related to initial steps of sex differentiation, and Wnt4, a gene related with ovarian development, close to the microsatellite and minisatellite markers, respectively. The position of Foxl2 and Wnt4 was confirmed by linkage mapping in the reference turbot map.

Detrusor Overactivity After Partial Bladder Outlet Obstruction Is Associated With High Urinary Adenosine Triphosphate Levels in Female Wistar Rats.

PURPOSE: Bladder outlet obstruction (BOO) commonly causes detrusor overactivity (DO). In this study, a post hoc analysis of previous obtained data, we investigate if DO occurring in initial phases of BOO is associated with changes in urinary adenosine triphosphate (ATP) levels. METHODS: Adult female Wistar rats were submitted to partial BOO (pBOO) or to sham obstruction. Cystometry was performed at 3 or 15 days after pBOO and saline voided was collected for ATP determination. Normality was tested using Shapiro-Wilk test. The mean frequency of voiding contractions (VCs) of the sham-operated animals at 15 days after surgery, plus or minus 3 standard deviations, was used to represent the normal range. Statistical analyses were performed using the chi-square and Mann-Whitney tests. RESULTS: DO was indicated by a VC frequency greater than or equal to 0.9 VCs/min. DO was observed in 63% of animals at 3 days and in 33% at 15 days following pBOO. ATP levels were significantly higher in rats with DO compared to those without DO. CONCLUSION: The DO phenotype, occurring in the initial phases of BOO, is associated with comparatively high urinary ATP levels.

A Peculiar Cause of Shock: Analysing Two Clinical Cases.

Introduction: Pheochromocytoma is a rare neoplasia arising from the adrenal medulla that secretes catecholamines. Those afflicted by this condition can present a wide range of symptoms. One of the most common is paroxysmic hypertension. Interestingly, although rare, some patients present with shock. We describe two cases of pheochromocytoma in which the initial presentation was shock. Case 1. 49 year-old woman, with a history of resistant hypertension, presented to the emergency department with thoracic pain and fever. EKG, echocardiogram (ECC), and myocardial necrosis markers were compatible with Takotsubo syndrome (TS). CT demonstrated a staghorn calculus, hydronephrosis, and signs compatible with xanthogranulomatous pyelonephritis in the right kidney. Additionally, and incidentally, it revealed a 60 mm nodule on the right adrenal gland. Piperacillin/tazobactam was started immediately, and the patient was submitted to urgent upper urinary tract drainage. This procedure was complicated by a cardiorespiratory arrest that was treated with adrenaline administration. The patient was admitted to the ICU due to multifactorial shock and started alpha and, posteriorly, beta blockage. Biochemical adrenal incidentaloma endocrinologic study was negative (under hemodialysis). Multiorgan failure progressively improved. After 2 weeks, the patient was submitted to a laparoscopic transperitoneal right adrenalectomy. No complications were reported. Histological analysis revealed a pheochromocytoma. Case 2. 28-year-old woman presented to the emergency department with headaches and nausea. Vitals were compatible with shock. CT revealed an incidental 72 mm mass on the right adrenal. EKG, ECC, and myocardial necrosis markers were compatible with TS. The patient was started on alpha and, posteriorly, beta blockage. Adrenal incidentaloma endocrinological study demonstrated high urinary catecholamines. Right transperitoneal adrenalectomy was performed. No complications were noted. Histological analysis revealed a pheochromocytoma. Conclusion: Pheochromocytoma can present with complex, enigmatic, and rare clinical pictures. Clinicians should be wary of the possibility of this diagnosis when managing adrenal masses.

Revealing Corynebacterium glutamicum proteoforms through top-down proteomics.

Corynebacterium glutamicum is a bacterium widely employed in the industrial production of amino acids as well as a broad range of other biotechnological products. The present study describes the characterization of C. glutamicum proteoforms, and their post-translational modifications (PTMs) employing top-down proteomics. Despite previous evidence of PTMs having roles in the regulation of C. glutamicum metabolism, this is the first top-down proteome analysis of this organism. We identified 1125 proteoforms from 273 proteins, with 60% of proteins presenting at least one mass shift, suggesting the presence of PTMs, including several acetylated, oxidized and formylated proteoforms. Furthermore, proteins relevant to amino acid production, protein secretion, and oxidative stress were identified with mass shifts suggesting the presence of uncharacterized PTMs and proteoforms that may affect biotechnologically relevant processes in this industrial workhorse. For instance, the membrane proteins mepB and SecG were identified as a cleaved and a formylated proteoform, respectively. While in the central metabolism, OdhI was identified as two proteoforms with potential biological relevance: a cleaved proteoform and a proteoform with PTMs corresponding to a 70 Da mass shift.

Incidence of urological cancers in neurological patients: a review of the literature from the EAU Young Academic Urologist Functional Group.

INTRODUCTION: Urological cancers can be challenging in the diagnosis and treatment of patients with neurological diseases. As a result, there are still uncertainties regarding the incidence and risk factors favouring the development of urological cancers in these patients. The aim of this study was to review the available evidence regarding the incidence for the development of urological cancers in neurological patients to provide a basis for future recommendations and research. EVIDENCE ACQUISITION: A narrative review of the literature in Medline and Scopus up to June 2019 was performed. EVIDENCE SYNTHESIS: After screening 1729 records, 30 retrospective studies were retained. For bladder cancer (BC), 21 articles were identified, including a total of 673,663 patients. Among these patients, 4744 had a diagnosis of BC (1265 females, 3214 males, gender not reported in 265). In this group, 2514 were diagnosed with BC associated with a neurological disease. For prostate cancer (PC), 14 articles were identified, including a total of 831,889 men. Among these patients, 67,543 had a diagnosis of PC and 1457 had PC and a neurological disease. Two articles reported kidney cancer (KC), one reported testicular cancer (TC) and none described penile cancer or urothelial carcinomas of the upper urinary tract in neurological patients. CONCLUSIONS: The incidence of urological cancers, especially BC and PC, in patients with neurological diseases appears comparable to the general population. However due to the paucity of studies, specific recommendations for the management are lacking in neurologically disabled patients. In this report we investigated the frequency of urinary tract cancers in patients with neurological diseases. We conclude that urological cancers, especially bladder and prostate cancer, in patients with neurological diseases occur with similar frequency as in the general population.

Sudden-Onset Disaster Mass-Casualty Incident Response: A Modified Delphi Study on Triage, Prehospital Life Support, and Processes.

The application and provision of prehospital care in disasters and mass-casualty incident response in Europe is currently being explored for opportunities to improve practice. The objective of this translational science study was to align common principles of approach and action and to identify how technology can assist and enhance response. To achieve this objective, the application of a modified Delphi methodology study based on statements derived from key findings of a scoping review was undertaken. This resulted in 18 triage, eight life support and damage control interventions, and 23 process consensus statements. These findings will be utilized in the development of evidence-based prehospital mass-casualty incident response tools and guidelines.

Secretome analysis of the fungus Trichoderma harzianum grown on cellulose.

Trichoderma harzianum is a mycoparasitic filamentous fungus that produces and secretes a wide range of extracellular hydrolytic enzymes used in cell wall degradation. Due to its potential in biomass conversion, T. harzianum draws great attention from biofuel and biocontrol industries and research. Here, we report an extensive secretome analysis of T. harzianum. The fungus was grown on cellulose medium, and its secretome was analyzed by a combination of enzymology, 2DE, MALDI-MS and -MS/MS (Autoflex II), and LC-MS/MS (LTQ-Orbitrap XL). A total of 56 proteins were identified using high-resolution MS. Interestingly, although cellulases were found, the major hydrolytic enzymes secreted in the cellulose medium were chitinases and endochitinases, which may reflect the biocontrol feature of T. harzianum. The glycoside hydrolase family, including chitinases (EC 3.2.1.14), endo-N-acetylglucosaminidases (EC 3.2.1.96), hexosaminidases (EC 3.2.1.52), galactosidases (EC 3.2.1.23), xylanases (EC 3.2.1.8), exo-1,3-glucanases (EC 3.2.1.58), endoglucanases (EC 3.2.1.4), xylosidases (EC 3.2.1.37), α-L-arabinofuranosidase (EC 3.2.1.55), N-acetylhexosaminidases (EC 3.2.1.52), and other enzymes represented 51.36% of the total secretome. Few representatives were classified in the protease family (8.90%). Others (17.60%) are mostly intracellular proteins. A considerable part of the secretome was composed of hypothetical proteins (22.14%), probably because of the absence of an annotated T. harzianum genome. The T. harzianum secretome composition highlights the importance of this fungus as a rich source of hydrolytic enzymes for bioconversion and biocontrol applications.

Analytical tool for optimization of position sensors based on eddy currents effect.

This paper proposes an open-source tool for a fast and precise calculation of the inductance of planar coils in the presence of conductive targets. This tool, based on Grover equations, is versatile to any coil and target geometries. The performance of this tool has been validated by comparing the analytical results with experimental data and Finite Element Model (FEM) simulations. When compared with the experimental measurements, the developed analytical model and the FEM simulation retrieved similar results, with differences below 4%. The proposed tool, in addition to requiring less computing resources, is significantly faster than FEM simulations. This shows the effectiveness of the proposed approach for the analytical calculation of the inductance of planar coils in the presence of conductive plates. It combines accuracy, versatility, speed, and no need for high computational resources.
