Safety and Feasibility of Enhanced Recovery after Surgery in Pediatric Colostomy Closure.

Aims: To study the safety and feasibility of enhanced recovery after surgery (ERAS) protocol in pediatric colostomy closure. Materials and Methods: Retrospective observational study of children who underwent colostomy closure. Data were collected from the electronic medical records and telephonic follow-up calls of patients from October 2013 to October 2023, in the Department of Pediatric Surgery of a Tertiary level Medical College. The parameters obtained were age, gender, type of stoma, primary diagnosis, discrepancy in luminal diameters, time to reach full feeds, postoperative hospital stay, and complications. The protocol followed for colostomy closure included the following-no bowel preparation or nasogastric tube, no overnight fasting, single dose of antibiotic prophylaxis, avoiding opioids, packing proximal stoma till mobilization and starting early oral feeds postoperatively. The continuous parameters were expressed as mean ± standard deviation or median (range) while the descriptive parameters were expressed as number and percentage. Results: A total of 90 patients were included in the study. Most of the patients had colostomy for anorectal malformation. Five of them had significant luminal discrepancy of 4 or more times. Full feeds were reached within 2 days in 79 patients. Postoperative hospital stay was 2-3 days in 62 patients. Six patients stayed for more than 5 days, due to complications requiring further management. We noted surgical site infection in 6 patients all of whom were managed with regular wound dressings and fecal fistula in 4 cases, two of which resolved spontaneously. Conclusion: ERAS protocol in colostomy closure reduces the hospital stay and is cost effective, with early recovery and no added complications.

Exploring the macrominerals and heavy metals profile of deep-sea fishes: A pioneering study on trawl bycatch and discards in the Arabian Sea.

This study assesses macrominerals (Na, K, Ca, Mg, P) and heavy metals (As, Cd, Cr, Cu, Ni, Pb, Se, Sn, Mn, Co, Fe, and Zn) content of deep-sea fish bycatch in the Arabian Sea, offering insights into their nutritional value, toxicant levels and health implications. Variations in Ca, K, P, Mg, and Na levels across species highlight mineral diversity. Setarches guentheri has the highest Ca (7716 mg/kg ww), K (2030.5 mg/kg ww), and P (13,180 mg/kg ww) concentrations. Dactyloptena orientalis exceeds the Cd limit (0.1284 mg/kg ww). Elevated Se levels in fishes were noted, with Dactyloptena orientalis (0.8607 mg/kg ww), Satyrichthys laticeps (0.7303 mg/kg ww), and Snyderina guentheri (0.6193 mg/kg ww). Fish like Pterygotrigla hemisticta contains high Zn (32 mg/kg ww), meeting Recommended Dietary Allowance limits. Deep-sea fish have safe heavy metal levels, but Cd, Se, and Zn exceed acceptable limits. It has been concluded that the consumption of fish species will not pose a potential health risk to humans.

Estimation of human somatype using inter-canine and inter-premolar distances of the maxillary arch.

Context: The establishment of a correlation between tooth dimensions and body size is crucial within the realm of forensic odontology. While numerous investigations have focused on the association between tooth morphology or width and stature, limited reports exist regarding the correlation between overall body structure or build and odontogenic parameters. This study focuses on finding a correlation between inter-arch dimensions and the body build of an individual. Aims: This study aimed to examine the potential correlation between an individual's somatotype (body build) and the measurements of inter-canine and inter-premolar maxillary arch widths. Study Settings: Dayananda Sagar College of Dental Sciences. Study Design: A cross-sectional study. Methods and Material: The sample size of the study was 153 individuals aged 18-25 years. Impressions for the maxillary arch were taken, study models were made and inter-arch measurements were taken using a digital Vernier calliper. For body build measurements, Heath-Carter somatotype measuring technique was used. The collected data were entered into an Excel sheet, and statistical analysis was done. Statistical Analysis Used: Principal component analysis. Results: On using principal component analysis, it was seen that there exists no correlation between body build of an individual when compared to inter-canine and inter-premolar distances. Conclusions: While no positive correlation has been seen between the odontometric parameters and specific body type, it can be argued that this can be due to the cited limitations of the study. Hence, we conclude with the note that a more detailed study would offer more viable and credible results.

A 33-Year-Old Woman With Breathing Difficulty, Inspiratory Wheeze, and Hemoptysis.

CASE PRESENTATION: A 33-year-old teacher from Ghana with no medical comorbidities and no relevant family history came to our pulmonology department with progressive difficulty in breathing, wheezing, and stridor for 6 months. Similar episodes had been treated previously as bronchial asthma. She was being treated with high-dose inhaled corticosteroids and bronchodilators but had no relief. The patient also described two episodes of large quantities of hemoptysis (> 150 mL) in the previous week. A general physical examination revealed a tachypneic young woman with an audible inspiratory wheeze. Her BP was 128/80 mm Hg; pulse, 90 beats/min; and respiratory rate, 32 breaths/min. There was a hard, minimally tender, nodular swelling of 3 × 3 cm in the midline neck felt just below the cricoid cartilage, moving with deglutition and protrusion of the tongue, with no retrosternal extension. There was no cervical or axillary lymphadenopathy. Laryngeal crepitus was present.

Estimation of ALU Repetitive Elements in Plasma as a Cost-Effective Liquid Biopsy Tool for Disease Prognosis in Breast Cancer.

BACKGROUND: Liquid biopsy is widely recognized as an efficient diagnostic method in oncology for disease detection and monitoring. Though the examination of circulating tumor cells (CTC) is mostly implemented for the assessment of genomic aberrations, the need of complex methodologies for their detection has impeded its acceptance in low-resource settings. We evaluated cell-free DNA (cfDNA) as a liquid biopsy tool and investigated its utility in breast cancer patients. METHODS: Total cell-free DNA was extracted from the plasma of breast cancer patients (n = 167) with a median follow-up of more than 5 years, at various stages of the disease. Quantitative PCR was performed to estimate the copy numbers of two fractions of ALU repetitive elements (ALU 115 and ALU 247), and DNA integrity (DI) was calculated as the ratio of ALU 247/115. Mutations in TP53 and PIK3CA in the cfDNA were estimated by next-gen sequencing (NGS) in a subset of samples. Associations of the levels of both the ALU fragments with various clinico-pathological factors and disease-free survival at various stages were examined. Nomogram models were constructed with clinical variables and ALU 247 levels to predict disease-free survival and the best performing model was evaluated by decision curve analysis. RESULTS: DI and ALU 247 levels were significantly lower (p < 0.0001) in the post-operative plasma when compared to their pre-surgery levels. DI and ALU 247 were found to be significantly higher in patients with metastasis (p < 0.05). Patients with higher levels of ALU 247 in their post-operative plasma had significant poor disease-free survival (p = 0.005). Higher levels of ALU 247 in the circulation also correlated with low tumor-infiltrating lymphocytes (TIL) within their primary tumors in the ER-negative breast cancer subtype (p = 0.01). Cox proportional hazard analysis confirmed ALU 247 as an independent variable of disease-free survival both in univariate and multivariate analysis [HR 1.3 (95% CI 1.047 to 1.613, p = 0.017)]. The nomogram model showed that the addition of ALU 247 with other variables significantly improved (C-index 0.823) the predictive ability of the model. CONCLUSION: Our results confirm the utility of cfDNA as an evolving liquid biopsy tool for molecular analysis. Evaluation of larger fragments of cfDNA estimated through ALU 247 can provide vital information concurrent with the pathological process of disease evolution in breast cancer and warrants expansion to other cancer types.

Establishing the reliability of incisive papilla and palatal rugae patterns in individual identification.

Context: The study of palatal rugae forms an important basis of human identification, especially due to mass disasters where routinely used techniques may not be helpful. Aims: This study aimed at evaluating the palatal rugae and incisive papilla on the basis of shape. Settings and Design: The study was conducted in 280 individuals (males and females) among dental students of Dayananda Sagar College of Dental Sciences. Materials and Methods: The study included 280 students from Dayananda Sagar College and out-patients from the orthodontics department. Pictures of rugae and the incisive papilla were taken from individuals aged 10-36 using a camera, mirror, and lighting. Two investigators analysed the shape of the rugae and incisive papilla using classification systems by Thomas and Kotze, and Ortman and Tsao, respectively. Statistical Analysis Used: The data were statistically analysed using SPSS 20.0 software, and a significance level of P ≤ 0.05 was used. Results: The results suggested that rugae showing a wavy shape were the most common pattern in both the genders. Significant differences were observed in the curved rugae type between males and females. In incisive papillae evaluation, the pear shape was the most common, with the triangular shape being the least common. Conclusions: It can be concluded that evaluation of palatal rugae along with the incisive papilla can be an important tool for identification of an individual and for evaluating various ethnic populations.

Oral Atenolol versus Propranolol in the Treatment of Infantile Hemangioma: A Systematic Review and Meta-Analysis.

Background: Infantile hemangioma (IH) is the most common benign vascular tumor of infancy. Propranolol is considered first-line therapy for IH. However, it is associated with side effects. Therefore, there was a need for alternative therapy. Atenolol, a selective b1-blocker may be free from such side effects. Hence, the present study aims to develop a more accurate estimate of the safety and efficacy of atenolol compared to propranolol in the treatment of IH. Methodology: A search of various literature databases (PubMed, Embase, Ovid, Scopus, Cochrane Central, CINAHL, Web of Science, and Google Scholar) was done to identify studies which compared propranolol versus atenolol in the treatment of IH. The combined odds ratio along with corresponding 95% confidence intervals (CIs) were evaluated using a fixed-effects model. Results: A total of 300 articles were screened of which five studies including 116 patients in atenolol arm and 138 patients in the propranolol arm were analyzed. Atenolol was comparable to propranolol in terms of efficacy as no significant difference was seen between both the treatment arms in terms of hemangioma activity score (mean difference 0.25 [95% CI;‒0.21, 0.71]) and complete response (odds ratio [OR] =0.43; 95% CI; 0.17, 1.11; P = 0.08,). Atenolol therapy was better than propranolol in terms of safety, i.e., serious/potentially serious side effect, (OR = 0.11; 95% CI; 0.02, 0.51; P = 0.005) and wheezing/bronchial hyperreactivity (OR = 0.11; 95% CI; 0.02, 0.51; P = 0.005). Conclusion: The present meta-analysis provides evidence that atenolol has got a comparable efficacy and better safety profile with propranolol.

Comparison of dexmedetomidine in two different doses on emergence agitation in children under sevoflurane anaesthesia: A double-blind randomised controlled trial.

BACKGROUND AND AIMS: Emergence agitation (EA) in children is one of the most common postoperative problems encountered in the recovery room. Sevoflurane has been strongly associated with EA owing to its lower solubility and rapid recovery. Dexmedetomidine has been found to reduce the incidence of EA. This study was designed to evaluate the effectiveness of dexmedetomidine in two doses in reducing EA in children. METHODS: This was a prospective double-blinded randomised study done on eighty children aged 5-14 years undergoing adenotonsillectomy/tonsillectomy under sevoflurane anaesthesia. Patients in Group A (n = 40) received 0.3 µg/kg/h and patients in group B (n = 40) received 0.5 µg/kg/h infusion after a bolus dose of 0.5 µg/kg of dexmedetomidine. The primary objective was to compare two different doses of dexmedetomidine on EA in the postoperative period. The secondary objectives were to assess the pain and perioperative haemodynamics in the recovery room. The anaesthesiologist blinded to the study charted the paediatric anaesthesia emergence delirium score (PAED), perioperative haemodynamic parameters, objective pain score and rescue medications if given. The data were analysed using Student's unpaired t-test, Chi-square test, repeated measures Analysis of Variance (ANOVA) and Mann-Whitney U test wherever appropriate. RESULTS: The incidence of EA was comparable between both groups (P = 0.960). The haemodynamic parameters (P > 0.05) and the objective pain score (P = 0.810) also did not show a statistically significant difference. CONCLUSION: A lower dose of dexmedetomidine (0.3 µg/kg/h) is equally effective as a higher dose (0.5 µg/kg/h) after a bolus dose of 0.5 µg/kg in decreasing EA.

Clinically relevant cell culture models and their significance in isolation, pathogenesis, vaccine development, repurposing and screening of new drugs for SARS-CoV-2: a systematic review.

BACKGROUND: In-Vitro/Cellular evidence is the backbone and vital proof of concept during the development of novel therapeutics as well as drugs repurposing against COVID-19. Choosing an ideal in-vitro model is vital as the virus entry is through ACE2, CD147, and TMPRSS2 dependant and very specific. In this regard, this is the first systematic review addressing the importance of specific cell lines used as potential in-vitro models in the isolation, pathogenesis, and therapeutics for SARS-COV-2. METHODS: We searched 17 literature databases with appropriate keywords, and identified 1173 non-duplicate studies. In the present study, 71 articles are included after a careful, thorough screening of the titles and their abstracts for possible inclusion using predefined inclusion/exclusion criteria (PRISMA Guidelines). RESULTS: In the current study, we compiled cell culture-based studies for SARS-CoV-2 and found the best compatible In-Vitro models for SARS-CoV-2 (Vero, VeroE6, HEK293 as well as its variants, Huh-7, Calu-3 2B4, and Caco2). Among other essential cell lines used include LLC-MK2, MDCKII, BHK-21, HepG2, A549,T cell leukemia (MT-2), stems cells based cell line DYR0100for differentiation assays, and embryo-specific NIH3T3 cell line for vaccine production. CONCLUSION: The Present study provides a detailed summary of all the drugs/compounds screened for drug repurposing and discovery purpose using the in-vitro models for SARS-CoV-2 along with isolation, pathogenesis and vaccine production. This study also suggests that after careful evaluation of all the cell line based studies, Kidney cells (VeroE6, HEK293 along with their clones), liver Huh-7cells, respiratory Calu-3 cells, and intestinal Caco-2 are the most widely used in-vitro models for SARS-CoV-2.

miRNAs: Critical mediators of breast cancer metastatic programming.

MicroRNA mediated aberrant gene regulation has been implicated in several diseases including cancer. Recent research has highlighted the role of epigenetic modulation of the complex process of breast cancer metastasis by miRNAs. miRNAs play a crucial role in the process of metastatic evolution by facilitating alterations in the phenotype of tumor cells and the tumor microenvironment that promote this process. They act as critical determinants of the multi-step progression starting from carcinogenesis all the way to organotropism. In this review, we focus on the current understanding of the compelling role of miRNAs in breast cancer metastasis.

The complementary nature of multimodal imaging in the management of an anomalous aortic origin of the right coronary artery from the left coronary cusp.

Anomalous aortic origins of coronary arteries (AAOCA) are congenital abnormalities involving the origin and course of coronary arteries and present with diverse clinical manifestations in patients ranging from asymptomatic incidental findings to sudden cardiac death. The current case describes a patient with an anomalous right coronary artery with an anterior interarterial course originating from a separate ostium at the left coronary cusp. By utilizing complementary multimodality imaging techniques including fractional flow reserve (FFRCT), we obtained a comprehensive functional and anatomic assessment resulting in appropriate surgical therapy and a good clinical outcome.

Hydralazine-Induced Dual Antineutrophil Cytoplasmic Antibody Positive Vasculitis and Nephritis.

Drug-induced autoimmunity occurs when exposure to a causative agent leads to serologic or clinical autoimmune responses. Syndromes that may be associated with drug-induced autoimmunity include antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) and drug-induced lupus (DIL). When drug-induced autoimmunity involves the kidney, histological patterns of injury include pauci-immune glomerulonephritis (GN), which occurs with AAV, and immune complex-mediated GN, which is associated with DIL. We present a case of hydralazine-induced dual ANCA-positive vasculitis and nephritis.

Calciphylaxis in the Setting of Hemodialysis, Liver Cirrhosis, and Warfarin Therapy for Atrial Fibrillation: An Argument for Alternative Anti-Embolic Therapy.

Calciphylaxis, also referred to as calcific uremic arteriolopathy, is a rare, life-threatening cutaneous systemic disease that typically occurs in the setting of end-stage renal disease (ESRD). ESRD is the most recognized risk factor for calciphylaxis but it is not the sole risk factor. Calciphylaxis has also been associated with liver cirrhosis with or without concurrent renal disease. The current case describes a patient who developed calciphylaxis in the setting of hemodialysis, liver cirrhosis, and atrial fibrillation managed with warfarin therapy, all risk factors for calciphylaxis. The need for alternatives to warfarin therapy, specifically in patients with atrial fibrillation on hemodialysis for ESRD who are at increased risk for calciphylaxis, is discussed. Specifically, the left atrial appendage occluder device is described and the need for interdisciplinary management of these patients is stressed.

COVID-19 pandemic: A review based on current evidence.

In December 2019, severe acute respiratory syndrome-coronavirus-2, a novel coronavirus, initiated an outbreak of pneumonia from Wuhan in China, which rapidly spread worldwide. The clinical characteristics of the disease range from asymptomatic cases or mild symptoms, which include nonspecific symptoms such as fever, cough, sore throat, headache, and nasal congestion to severe cases such as pneumonia, respiratory failure demanding mechanical ventilation to multi-organ failure, sepsis, and death. As the transmission rate is quite alarming, we require an effective therapeutic strategy to treat symptomatic patients and adopt the preventive measures in order to contain the infection and prevent community transmission. Coronavirus disease 2019 (COVID-19) pandemic is a public health emergency of international concern, hence repurposing of the drugs is an attractive and a feasible option because PK/PD profile, toxicity profile, and drug interactions are already known. This review emphasizes on the different aspects of COVID-19 such as the epidemiology, etiopathogenesis, diagnosis, and preventive measures to be adopted in order to fight this pandemic. It also highlights upon the ethics preparedness and challenges faced by a developing country like India during such an outbreak. The review focuses on the various approaches adopted till date for developing effective therapeutic strategies including combination of drugs, vaccine therapy, and convalescent plasma therapy to combat this viral outbreak.

Athlete Biological Passport: Need and Challenges.

The Athlete Biological Passport programme was initiated in 2009 by the World Anti-Doping Agency for making the anti-doping programme more effective and stronger. There are three modules in this ABP programme: haematological, steroidal and endocrinological. Currently, the first two modules have been implemented. The newer products such as recombinant human erythropoietin, recombinant proteins, and peptides are similar to those produced naturally. Hence, detection of these substances even with advanced techniques is difficult. Therefore, the concept of ABP came into existence which is based on longitudinal monitoring of biological markers and their variations over a period of time. The ABP does not rely upon the detection of a particular prohibited substance but it reflects the changes in biological markers collated over an athlete's career. Hence, athletes can be monitored through constant interpretation of the passport data. There are many advantages with the implementation of this programme; however, there are various issues which may lead to false interpretation of passport data that must be taken into consideration.
