Numerical investigation of Merkel simplifying assumptions for the thermal analysis of forced draft wet cooling tower
Authors: Hamed Djalal
Published: July 2024

The heat-mass transfer in the packing zone of a forced draft wet cooling tower is investigated in the present study by two different one-dimensional models like Merkel model and the Klimanek and Bialecki model. Merkel's model is based on Merkel simplifying assumptions, unlike Klimanek and Bialecki's model. After the ordinary differential equations, systems are derived for both the models, then, these equations systems are solved numerically by the Runge-Kutta method, to carry out, the water and the air temperatures, the humidity, and also other proprieties variation along the packing zone. Finally, after we have compared the results of both models with the same experimental data of a laboratory cooling tower. It has been noticed that both models are very accurate; however, the differences between the results of Merkel and Klimanek and Bialecki models with the experimental data at the packing outlet, are respectively about 0.14°C and 0.67°C for the water temperature, 0.07°C and 0.17°C for the air temperature. Furthermore, the relative humidity becomes 0.89% and 0.18% less in Merkel and Klimanek and Bialecki models respectively as compared to the experimental data for the same operating condition. Finally, it is noticed that the Merkel model is advantageous because of its easier equation derivation and is slightly more accurate than the Klimanek and Bialecki model.
Traces across Time: Investigating an Unfinished Female Portrait by Sir Joshua Reynolds
Authors: Pointon Marcia
Published: July 2024

A portrait by Sir Joshua Reynolds of an unidentified female sitter depicts only a face and a diamond breast jewel. Once owned by John Ruskin and then by Kenneth Clark, the portrait offers an opportunity to examine assumptions we make when discussing historic portraiture. What may we infer from the collectors who were drawn to this enigmatic object? How do judgements about sitters’ identities change? What is meant by finish? How might traces of ownership of a particular work - what we call ‘provenance’ - contribute to our understanding of the work itself? What can we tell from the material of a painting, that is, from its pigments and support, about how an artist ran his studio? How might accessories determine meaning? I disentangle and identify some of the assumptions taken for granted when discussing portraiture while at the same time re-evaluating a disputed and neglected work.
Cancer pain: neurosurgical strategies
Authors: Meglio Mario , Cioni Beatrice , Morales Andreas , Visocchi Massimiliano
Published: July 2024

In common understanding, the term “pain” can take on different meanings: that of a specific sensation as a result of bodily evil, that of a feeling or state of deep unhappiness due to dissatisfaction of individual needs, aspirations or tendencies, that of an event or thing that produces pain, torment. Each of us uses this word to express different feelings, emotions or states of mind, making the problem of defining pain not easy to solve.

Published: July 2024

Introduction:

The study aims to assess the procedural outcomes and follow-up after transcatheter closure of ventricular septal defects (VSDs) in children utilizing the Konar-MF™ occluder (Lifetech Scientific, Shenzhen, PRC) device.

Materials and Methods:

Clinical features, demographic characteristics, and follow-up findings of children undergoing percutaneous VSD device closure were retrospectively analyzed from the medical records.

Results:

Fifty-seven patients underwent VSD closure using the Konar-MF occluder between January 2019 and April 2023. Median age and body weight of patients were 36 (5–216) months and 12.5 (3.8–42) kg, respectively. The mean size of the defect on the left ventricular side was 6.5 ± 2.4 mm on echocardiography; the mean pulmonary artery pressure was 19.1 ± 9.7 mmHg. Three patients with severe pulmonary hypertension had successful device closure. The most used device size was 8 mm × 6 mm. The initially chosen device was upsized in 4 (7.01%) patients and downsized in 1 (1.7%) patient. Forty-five patients (78.9%) had device closure through the retrograde route. The procedure was successful in 53 (93.0%) patients. Immediate shunt occlusion was achieved in 86.8% of patients. Major complications, namely, embolization (1) and moderate aortic regurgitation (1) in two patients were successfully managed by surgery. One patient with severe tricuspid regurgitation has been on close follow-up. There was no mortality. Late complications such as valve regurgitation or rhythm disturbance were not identified on a median follow-up of 6 (1.5–47) months.

Conclusion:

Transcatheter VSD closure using a Konar-MF occluder device is safe and effective, even in smaller children. The ability to deliver both anterogradely and retrogradely is a unique advantage.
Transcatheter management of superior vena cava obstruction following cardiac surgery: A case report from a resource-limited set-up
Authors: Islam Nurul , Saha Siddhartha
Published: July 2024

Obstruction of the superior vena cava (SVC) is a rare complication after cardiac surgery in infants and children. We present the case of an 8-year-old boy who underwent bi-directional Glenn shunt followed by takedown of Glenn shunt and complete repair for cyanotic congenital heart disease. After 4 years of surgery, the child developed features of superior vena caval (SVC) syndrome. Echocardiography and CT angiography revealed complete obstruction of SVC without any forward flow. Transcatheter intervention was performed successfully to re-canalize and stent the SVC to maintain its patency. The patient was doing well at follow-up appointments, with good laminar flow through the stent. In conclusion, transcatheter management of post cardiac surgery SVC obstruction was successful in this patient.
Mitral annular disjunction with atrial septal defect in children: An intriguing association
Authors: Agarwal Mridul , Relan Jay , Aggarwal Neeraj , Joshi Raja
Published: July 2024

Mitral annular disjunction (MAD) is defined as a separation between the mitral annulus and the left ventricular myocardium and is most often seen in association with mitral valve prolapse (MVP). MAD has been linked to ventricular arrhythmias in adults, independent of MVP. However, it has rarely been reported in children. We, hereby, report two cases of MAD associated with a large atrial septal defect (ASD). Thus far, there are no consensus guidelines for the management of MAD. The additional association of large ASD further complicates the decision-making in these patients. To the best of our knowledge, this is the first report of the association of MAD with ASD. We further discuss the challenges in the management of this condition.

Introduction:

Permanent pacemaker implantation (PPI) in neonates is challenging with respect to indications, device selection, implantation technique, and long-term outcomes. Complex anatomy, the need for long-term pacing with high rates, and a problematic postoperative period are the major problems.

Methods:

We prospectively followed up 22 newborns who underwent PPI below 28 days of life at our institute.

Results:

The median age at implantation was 2 days (interquartile range 1–9 days), and 9% were born preterm. The average heart rate before implantation was 46.4 ± 7.2 bpm. Maternal lupus antibodies were positive in 8 (36.4%) neonates, whereas 11 (50.0%) had associated congenital heart disease. Nineteen neonates underwent single chamber (VVI) and three underwent dual chamber (DDD) pacemaker implantation. Over a median follow-up of 46 months (range 2–123 months), the average ventricular pacing percentage was 87.5 ± 24.9%, with a stable pacing threshold. Seven children underwent pulse generator replacement due to battery depletion at a median age of 47 months. Pacing-induced ventricular dysfunction was seen in five children at a median age of 23.6 months, and two underwent upgradation to cardiac resynchronization therapy. Overall mortality was 13.6%, all due to tissue hypoperfusion and lactic acidosis in the postimplantation period.

Conclusions:

PPI in neonates has a favorable outcome with excellent lead survival. Overall mortality is 13.6%, which is predominantly in the postimplantation period and related to myocardial dysfunction.
Artificial intelligence-based model for automatic real-time and noninvasive estimation of blood potassium levels in pediatric patients
Authors: Torshizi Hamid Mokhtari , Omidi Negar , Khorgami Mohammad Rafie , Jamali Razieh , Ahmadi Mohsen
Published: July 2024

Background:

An abnormal variation in blood electrolytes, such as potassium, contributes to mortality in children admitted to intensive care units. Continuous and real-time monitoring of potassium serum levels can prevent fatal arrhythmias, but this is not currently practical. The study aims to use machine learning to estimate blood potassium levels with accuracy in real time noninvasively.

Methods:

Hospitalized patients in the Pediatric Department of the Rajaie Cardiology and Medical Research Center and Tehran Heart Center were recruited from December 2021 to June 2022. The electrocardiographic (ECG) features of patients were evaluated. We defined 16 features for each signal and extracted them automatically. The dimension reduction operation was performed with the assistance of the correlation matrix. Linear regression, polynomials, decision trees, random forests, and support vector machine algorithms have been used to find the relationship between characteristics and serum potassium levels. Finally, we used a scatter plot and mean square error (MSE) to display the results.

Results:

Of 463 patients (mean age: 8 ± 1 year; 56% boys) hospitalized, 428 patients met the inclusion criteria, with 35 patients having a high noise of ECG were excluded. After the dimension reduction step, 11 features were selected from each cardiac signal. The random forest regression algorithm showed the best performance with an MSE of 0.3.

Conclusion:

The accurate estimation of serum potassium levels based on ECG signals is possible using machine learning algorithms. This can be potentially useful in predicting serum potassium levels in specific clinical scenarios.
Prevalence of use of nonpharmacological methods of pain relief among patients following onco surgeries – A prospective, observational cohort study from a single center
Authors: Bakshi Sumitra G. , Arya K , Dhurwe Badal
Published: July 2024

Background and Aims:

For the aggressive treatment of postoperative pain, nonpharmacological methods (NPMs) are gaining importance complementary to routine multimodal pain management. The primary aim of the study was to assess the incidence of use of NPMs in our hospital. Secondary objectives were to correlate the pain scores, patient satisfaction, and percentage of time the patient was in severe pain within 72 h postsurgery with the use of NPMs when in pain/not in pain. The effect of NPMs on the physical and emotional outcome of patients as per the American Pain Society Patient Outcome Questionnaire (APS-POQ) was also assessed.

Material and Methods:

After obtaining approval from the institutional ethics committee (IEC), the trial was registered with the Clinical Trials Registry of India (CTRI). Informed consent was obtained from adult patients on the third postoperative day of elective surgeries. Their responses to the APS-POQ and to a few additional questions about their beliefs on the use of NPM were recorded.

Results:

Only one-fourth of the total study population were using NPMs for pain management in the hospital. After propensity matching for surgery and postoperative analgesia, two groups were made: one using NPM for pain relief (n = 49) and the other not using NPM (n = 98). There was no significant difference among the satisfaction score (P = 0.31), least pain score (P = 0.68), and worst pain score (P = 0.43) within 72 h postoperatively in either of the groups. Emotional and physical outcomes as per the APS-POQ were similar in both the groups.

Conclusion:

NPMs are rarely practiced and used during postoperative pain in our hospital. No difference in pain scores, patient satisfaction, and emotional and physical outcomes of the APS-POQ was seen in the group that indulged in NPMs.
Efficacy and safety of sublingual buprenorphine in managing acute postoperative pain – A systematic review
Authors: Nair Abhijit S. , Dudhedia Ujjwalraj , Bodas Prasad Vilas , Rangaiah Manmohan , Borkar Nitinkumar
Published: July 2024

Sublingual (SL) buprenorphine has been used as a modality of managing acute postoperative pain in many studies. This systematic review aimed to investigate the safety and efficacy of SL buprenorphine as an analgesic for various surgeries. After registering the protocol with PROSPERO, we searched PubMed, Cochrane Library, and Ovid databases with relevant keywords. The primary outcomes were 24-hour pain scores, and the secondary outcomes were postoperative nausea and vomiting, sedation scores, pruritus, rescue analgesia, and urinary retention. The risk of bias scale was used to identify the quality of evidence. From the 103 articles identified, four randomized-controlled trials fulfilled the inclusion criteria for qualitative analysis. The overall risk of bias was low. Most of the studies showed that the use of SL buprenorphine led to either better or comparable pain scores when compared to a control group with lesser or tolerable adverse events. There was a lot of heterogeneity across the studies in this systematic review in terms of the type of surgery performed, the comparison groups, doses of buprenorphine, and the outcomes that were assessed. Therefore, a quantitative meta-analysis was not performed. The results of this systematic review should be interpreted with caution due to heterogeneity in the methodology. Adequately powered studies with robust methodology should investigate the safety and efficacy of SL buprenorphine when used for postoperative analgesia.

Authors: Prajapati Dinesh J. , Patel Manoj , Patel Pankaj , Ganpule Arvind , Mistry Deepak
Published: July 2024

Background and Aims:

Enhanced recovery after surgery (ERAS) has been applied in various laparoscopic procedures. Intravenous lidocaine (IVL) infusion is used for laparoscopic procedures as a part of ERAS protocols. The study aimed to evaluate the role of IVL infusion in enhanced bowel recovery after laparoscopic renal surgeries.

Material and Methods:

A randomized, double-blind, placebo-control trial was conducted on 80 patients (with American Society of Anesthesiologists physical status I–II) who presented for laparoscopic renal surgeries under general anesthesia. The study period was from Oct 2018 to Sept 2019. By computer-generated codes, patients were randomly divided into two groups: L (lidocaine) and C (control). Group L received an intravenous (IV) bolus (1.5 mg/kg) of 2% lidocaine over 2 min, followed by an IV lidocaine infusion at the rate of 1.5 mg/kg/h until skin closure. Group C received the same volume of bolus followed by normal saline infusion. Patients were monitored for bowel functions, total hospital stay, and total analgesic consumption. Student’s t-test and Chi-square test were used for quantitative data and occurrence of events, respectively. P <0.05 was considered to be statistically significant.

Results:

First bowel sound, flatus, and defecation occurred in 16.4 ± 2.50, 26.7 ± 9.02, and 39.1 ± 6.31 h, respectively, in group L and 18.2 ± 2.90, 32.3 ± 3.11, and 43.3 ± 4.22 h, respectively, in group C (P = 0.006, 0.001, and 0.01, respectively). Total hospital stay was 4.0 ± 0.74 and 5.3±0.0.91 days in groups L and C, respectively (P < 0.001).

Conclusion:

The present study concluded that IVL could enhance the bowel recovery and reduce total hospital stay after laparoscopic renal surgeries.
“Weighing it Down”: Technique to Reduce the Weight of an Obturator
Authors: Nanda Aditi , Kaur Harsimran , Koli Dheeraj
Published: July 2024

Objective:

The objective during the obturator fabrication (interim or definitive) should be to reduce the weight of the obturator prosthesis. This is because the increased weight of the maxillary obturator is detrimental to the success of the prosthesis due to decreased retention (pulled by gravity), constant rubbing of prosthesis on mucosa and increased patient discomfort.

Design and Interventions:

Of the many simple baby-steps to ensure enhanced retention of the prosthesis, a simple method to reduce the weight has been described using the subtractive technique of obturator fabrication.

Results:

Reduced weight of the obturator prosthesis which makes the prosthesis more acceptable to the patient and more successful overall.

Authors: Mba Emmanuel Louis , Guduf Mohammed Ibrahim , Mshelia Nuhu Musa , Babayo Usman Deba , Misauno Michael Ayedima , Wina Felix Markus
Published: July 2024

Background:

Appendectomy could be open or laparoscopic. Laparoscopic appendectomy (LA) is gradually gaining ground in Nigeria, but its outcome is not entirely known.

Objective:

This study compared the outcomes of LA with those of open appendectomy (OA) in terms of the surgical site infection rate, post-operative pain, time to return of bowel sounds, length of hospital stay, return to normal activities and direct cost of treatment.

Patients and Methods:

This was a prospective randomised study. All patients above 18 years who were diagnosed with acute appendicitis in Federal Teaching Hospital, Gombe, were recruited after adequate counselling and consent obtained over the 18 months of the study.

Results:

Forty (40) patients were recruited with 20 on each arm. The average age was 25 years (±) 6 years and M:F was 1:1.9. The rates of surgical site infection and post-operative pain between both methods were not statistically different, while the time to return of bowel sound, the length of hospital stay and the return to normal activity were significantly reduced in LA compared to OA. However, OA was cheaper in terms of direct cost compared to LA.

Conclusion:

This study showed that LA may be the preferred method when a quicker recovery from treatment is anticipated, provided the patient can afford the direct cost of the procedure.

DFT Study and Topological Analysis of the Electron Density of the Casearvestrin
Authors: Zambrano-Angulo Michael , Mejía Sol M. , Tilvez Elkin
Published: July 2024

Casearvestrin A, B, and C secundary metabolites, with a promising anticancer potential, were computationally characterized to reveal susceptible sites to nucleophilic and electrophilic attacks, establishing the types and strength of chemical bonds and non-covalent interactions using the B3LYP/6-311++G(d,p) theory level. The chemical behavior prediction was performed by the analysis of local besides global reactivity indexes based on the analysis of the Fukui functions and the topological analysis of the electronic density according to Bader’s theory. Casearvestrin A is the most reactive molecule since it has less hardness, smallest band gap, a highest number of C-H--O weak interactions, and both type of susceptible sites, nucleophilic and electrophilic. Electrophilic attacks are most favored at oxygen atoms of the carbonyl groups, the hydroxyl group, and the cyclic ether. The length of the R chain, which differentiates this type of metabolites, is related to the number of H--H interactions, which in turn has a relationship with the dipole moment

En este artículo se presenta una simulación matemática de la versión más simple del efecto Zeeman de un campo magnético. En esta simulación, se adopta un tratamiento matricial de un problema inverso. El problema consiste en determinar una matriz a partir de un conjunto de números que, por imposición, serán los valores propios de dicha matriz. Partiendo de una matriz que presenta máxima degeneración de sus valores propios, se consideran tres simulaciones: una preservando la degeneración inicial; una rompiendo parcialmente esta degeneración, y la otra rompiendo totalmente la degeneración inicial. Se presentan consideraciones físicas que podrían corresponder a estas simulaciones.
Partial Proof of a Conjecture with Implications for Spectral Majorization
Authors: Uhlmann Jeffrey
Published: July 2024

In this paper we report on new results relating to a conjecture regarding properties of $n\times n$, $n\leq 6$, positive definite matrices. The conjecture has been proven for $n\leq 4$ using computer-assisted sum of squares (SoS) methods for proving polynomial nonnegativity. Based on these proven cases, we report on the recent identification of a new family of matrices with the property that their diagonals majorize their spectrum. We then present new results showing that this family can extended via Kronecker composition to $n>6$ while retaining the special majorization property. We conclude with general considerations on the future of computer-assisted and AI-based proofs.

This study aimed at evaluating the pH, nutrient content and nutrient loss of silage that were made of different ages Red Napier grass (Pennisetum purpureum cv. Red) and the addition of Lactobacillus plantarum. The experiment employed Nested Completely Randomized Factorial Design consisted 2 treatment factors i.e. the grass of 50, 60, 70 and 80 harvested days after planting as first factor and the addition of three levels of Lactobacillus plantarum i.e. 0, 103 and 106 cfu/g as second factor. Each factor combination was replicated 3 times. Collected data were subjected to analysis of variance followed by Duncan’s Multiple Range Test (DMRT). It was found that harvest ages did not affect pH (p>0.05) but level of L plantarum significantly (p<0.05) affect silage pH measured at day 7 and highly significantly (p<0.01) affect pH at day 14, and 21. L plantarum significantly (p<0.05) affect DM loss, and highly significant (P<0,01) affect OM loss, while the different harvesting ages gave highly significant (P<0,01) affect CP loss.The higher level of L. plantarum can increase the DM, CP and decrease levels of CF, NDF and ADF. It can be concluded that interaction between Red Napier grass of 50 harvested days after planting and addition of L. plantarum 106 cfu/g produced the good quality silage based on the relatively low weight loss of DM, OM and CP.
