Implementation of Combined Machine Learning with the Big Data Model in IoMT Systems for the Prediction of Network Resource Consumption and Improving the Data Delivery.

In recent years, health applications based on the internet of medical things have exploded in popularity in smart cities (IoMT). Many real-time systems help both patients and professionals by allowing remote data access and appropriate responses. The major research problems include making timely medical judgments and efficiently managing massive data utilising IoT-based resources. Furthermore, in many proposed solutions, the dispersed nature of data processing openly raises the risk of information leakage and compromises network integrity. Medical sensors are burdened by such solutions, which reduce the stability of real-time transmission systems. As a result, this study provides a machine-learning approach with SDN-enabled security to forecast network resource usage and enhance sensor data delivery. With a low administration cost, the software define network (SDN) design allows the network to resist dangers among installed sensors. It provides an unsupervised machine learning approach that reduces IoT network communication overheads and uses dynamic measurements to anticipate link status and refines its tactics utilising SDN architecture. Finally, the SDN controller employs a security mechanism to efficiently regulate the consumption of IoT nodes while also protecting them against unidentified events. When the number of nodes and data production rate varies, the suggested approach enhances network speed. As a result, to organise the nodes in a cluster, the suggested model uses an iterative centroid technique. By balancing network demand via durable connections, the multihop transmission technique for routing IoT data improves speed while simultaneously lowering the energy hole problem.

Utility of serum and salivary lactate dehydrogenase and uric acid levels as a diagnostic profile in oral squamous cell carcinoma patients.

Background: Lactate dehydrogenase (LDH), an intra-cellular enzyme present in all cells of the body, catalyses the final step of anaerobic glycolysis. This intra-cellular enzyme is released into the extra-cellular space after tissue disintegration, which is evident in oral squamous cell carcinoma (OSCC). However, investigations comparing Lactate dehydrogenase (LDH) levels in OSCC and healthy controls have shown conflicting findings in both serum and saliva samples. Further, Uric acid's anti-oxidant activity has been demonstrated in several diseases. Several cancers have been linked to increased uric acid levels. However, uric acid levels in oral squamous cell cancer have varied. There exists limitted research comparing serum and salivary uric acid with OSCC. Thus, the present investigation was conducted to evaluate the combined diagnostic abilities of serum and salivary LDH and uric acid in OSCC. Aim and Objective: To compare and correlate LDH and uric acid levels in serum and salivary samples of OSCC patients and healthy individuals. Material and Methods: LDH levels and uric acid levels were measured using an enzymatic method in serum and salivary samples of OSCC cases (n = 18) and healthy individuals (n = 18). Results: This study indicated statistically significant elevated levels of LDH in serum and saliva samples of OSCC patients when compared to healthy individuals. Furthermore, serum and salivary uric acid were higher in OSCC patients than in controls. This increased levels of uric acid was significant only in serum but not in saliva samples. However, salivary uric acid was found to be co-relating with serum uric acid. In addition to this, the receiver operating characteristic (ROC) curve when plotted to assess combined diagnostic abilities of all the investigations to predict oscc, indicating the diagnostic ability to be 77%. Conclusion: This study found an increase in uric acid levels in OSCC patients, which contradicts previous existing litratures. Salivary uric acid and LDH levels may be effective indicators for OSCC screening. However, because of the limited sample size, these findings should be viewed with caution.

Seeing the National Education Policy 2020 through the lens of early child development.

Early childhood education is the foundation for future academic success and life skills. India's third National Educational Policy emphasises on improving the quality of early learning. This curriculum aligns with the basic theories and stages of early child development, which if effectively implemented leads to holistic development and learning.

Characterization of plastic debris from surface waters of the eastern Arabian Sea-Indian Ocean.

The quantity of floating plastic debris (FPD) is continuously being increased in the oceans. To assess their size, structure, and composition along the eastern Arabian Sea (EAS), FPD samples were collected by using a surface plankton net. The microplastic size fraction (0.5-5 mm) was the most prevalent accounting for >50% of the total, followed by mesoplastics (5-25 mm; ~40%) and macroplastics (>25 mm; ~10%). The collected FPDs were categorized into five different types and eight colours. Attenuated Total Reflectance-Fourier Transform Infrared Spectrometry (ATR-FTIR) analysis of the plastics revealed that polypropylene, polyethylene, and nylon were the most dominant polymers, and these comprised mostly of fibre/fishing line. The abundance of FPD in the EAS (0.013 ± 0.012 no.s/m3) was found to be very low compared to elsewhere. The prevalent microplastics presence in the oceans might have occurred mainly by the degradation of larger items. It increases bioavailability, and hence, is a risk to marine ecosystems.

A Case Report of Cardiobacterium hominis Endocarditis in a Pregnant Woman.

Infective endocarditis (IE) is an infrequent endovascular disease, which can result in significant mortality and morbidity. Staphylococcus aureus and viridans streptococci remain the most common etiological agent. Cardiobacterium hominis, a member of the HACEK (Haemophilus species, Aggregatibacter species, Cardiobacterium hominis, Eikenella corrodens, and Kingella species) group of fastidious gram-negative bacillus, is a part of normal upper respiratory flora and a rare cause implicated in IE. Cases of Cardiobacterium hominis endocarditis are being increasingly reported in last few years due to advancement in automated blood culture system such as BacT/ALERT Virtuo® and identification system such as MALDI-TOF MS (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry). We herein report a first case of Cardiobacterium hominis endocarditis in a pregnant woman at 20 weeks of gestation. Following spontaneous abortion and evacuation of the fetus, appropriate surgical intervention under heparinized condition and pathogen-directed medical intervention was initiated in this patient. This case report highlights the importance of appropriate antimicrobial therapy, which augments earlier resolution of the disease.

Coronavirus disease 2019 and the inevitable increase in screen time among Indian children: Is going digital the way forward?

The world is facing an unprecedented crisis due to the Coronavirus disease catastrophe. The pandemic has been ravaging for the past six months claiming human lives, causing financial loss, and job insecurity. Children are susceptible to the psychosocial aspects of this pandemic. Being locked indoors there is exorbitant media exposure among children. The debate of digital media technology is now challenged by the pandemic. Digital technology is a boon during this crisis being a platform for both education and recreation. In the background of this inadvertent increases screen exposure we discuss the various health concerns and the need to balance media appropriately to carry it forward during this crisis which shows no sign of waning.

Synchronous double malignancy of lip and submandibular salivary gland with rare histology.

In the modern era, there is an increase in the incidence of double malignancies owing to the remarkable improvement in cancer diagnostics and patient survival. Double malignancies can be either synchronous or metachronous. Synchronous double malignancy can present either at the same time or within 6 months of diagnosis of the first one. We present a case of double malignancy of lip and submandibular salivary gland, diagnosed in a 55-year-old male, who presented with ulceroproliferative lesion of the upper lip and a hard swelling in the right submandibular gland. The tissue diagnosis was suggestive of squamous cell carcinoma of the lip and mucoepidermoid carcinoma of the submandibular gland. The patient underwent successful wide local excision of the lip and submandibular gland along with prophylactic supraomohyoid neck dissection. This case is reported for the rarity in site and histopathology of double malignancy.

Squamous Cell Carcinoma of the Breast Mimicking Chronic Breast Abscess.

Primary squamous cell carcinoma (SCC) of the breast is an exceedingly rare malignancy, and there are no clear management protocols for SCC of the breast. We report a 45-year-old female patient who presented with the recurrent breast abscess and a large fungating SCC of the breast with fixed ipsilateral axillary nodes. She was offered modified radical mastectomy. During the follow-up visits, she was observed to have developed multiple vertebral metastases. She had palliative chemotherapy. However, the patient succumbed to the disease within 6 months of the diagnosis.

Ascaridial Volvulus: An Uncommon Cause of Ileal Perforation.

Ascariasis is a common worm infestation in developing and under-developed countries. It is caused by the ingestion of food contaminated with Ascaris eggs from faeces and is more common in places with poor sanitation. Almost 25% of the world population is infested by Ascaris lumbricoides. Although ascariasis is a chronic disease, it can present as acute abdomen rarely. The wandering nature of Ascaris in and out of the bowel causes various abdominal complications such as intestinal obstruction, perforation, biliary ascariasis, pancreatic ascariasis, liver abscess, appendicitis, and Meckel's diverticulitis. Intestinal obstruction is the most common complication seen in children and is usually due to mechanical bowel obstruction, volvulus or intussusception. Mechanical obstruction by a bolus of worms is the most common cause of bowel obstruction. Perforation of bowel is rarely reported and it usually occurs in the diseased segment of bowel or following trauma. Perforation of an ileal volvulus secondary to ascariasis has been reported rarely. We present a 4-year-old boy who presented to the emergency room with features of bowel perforation and sepsis, after unsuccessful management for intestinal obstruction in another hospital. On laparotomy, the small bowel was teaming with Ascaris worms. Ileum showed a volvulus with closed loop obstruction and perforation. Peritoneal lavage with resection and ileostomy was done, which was closed at a later date. Anti-helminthic agents were started postoperatively and the boy recovered uneventfully.

Right atrial appendage tachycardia: A rare cause of tachycardia induced cardiomyopathy in a 4-year-old child.

We present a rare case of tachycardiomyopathy in a 4-year-old girl. The child had incessant atrial tachycardia (AT) and refractory heart failure. Right atrial appendage (RAA) was localised as the source of the ectopic tachycardia. The child underwent successful radiofrequency ablation (RFA) using 3-D electroanatomical mapping. Fluoroscopy was used sparingly only to rule out underlying anomalies. The left ventricular functions returned to normal by one month after the procedure. RAA AT is rare in very young children and usually necessitates surgical appendectomies. RFA is a challenge in such age groups and there are very few published literature on RAA AT in very young children.

Meckel's Diverticulitis Masquerading as Acute Pancreatitis: A Diagnostic Dilemma.

Meckel's diverticulum is a remnant of the proximal part of the vitellointestinal duct and is the most common congenital anomaly of the gastrointestinal tract. It may either remain asymptomatic or present with myriad of clinical presentations. Gastrointestinal bleeding is the most common presentation in children whereas it is intestinal obstruction in the case of adults. We report a 9-year-old boy who presented with acute onset of periumbilical pain and nonbilious vomiting. His clinical and laboratory parameters were unremarkable, except for serum amylase levels. He was conservatively managed initially as acute pancreatitis with paralytic ileus. However, the child deteriorated in a course of 2 days with bilious vomiting, abdominal distension, and dehydration. Imaging was suggestive of an ileoileal intussusception, and exploratory laparotomy identified Meckel's diverticulum as the lead point for the intussusception. The histopathological examination revealed inflamed heterotopic pancreatic tissue at the apex of the diverticulum thus explaining the elevated amylase levels. This case is reported to highlight the atypical presentation of Meckel's diverticulum and the high clinical suspicion warranted in diagnosing such concomitant intussusception.

Rare Presentation of Congenital Diaphragmatic Hernia in a Sexagenarian.

Congenital diaphragmatic hernia (CDH) usually presents in the neonatal period, and about 10% of reported cases occur in adults. The most common type is Bochdalek's hernia, which occurs through a defect in the posterolateral portion of the diaphragm with an estimated prevalence of 1 in 2500 live births. CDH in adults presents with gastrointestinal or respiratory symptoms, which can be acute or intermittent. We report a case of CDH diagnosed in a 55-year-old man, who presented with acute onset of chest pain and dyspnea with insignificant past history. This patient was initially evaluated medically for myocardial infarction followed by intercostal chest drainage placement, before a definitive diagnosis of CDH was made. This case is reported for its rarity and to highlight the high index of suspicion needed to diagnose CDH in adulthood. This is specially important as CDH, masquerades as other acute conditions in older individuals thereby delaying the diagnosis.

Effectiveness of flow inflating device in providing Continuous Positive Airway Pressure for critically ill children in limited-resource settings: A prospective observational study.

BACKGROUND AND AIMS: Noninvasive ventilation (NIV) is an emerging popular concept, which includes bi-level positive airway pressure or continuous positive airway pressure (CPAP). In settings with scarce resources for NIV machines, CPAP can be provided through various indigenous means and one such mode is flow inflating device - Jackson-Rees circuit (JR)/Bain circuit. The study analyses the epidemiology, various clinical indications, predictors of CPAP failure, and stresses the usefulness of flow inflating device as an indigenous way of providing CPAP. METHODS: A prospective observational study was undertaken in the critical care unit of a Government Tertiary Care Hospital, from November 2013 to September 2014. All children who required CPAP in the age group 1 month to 12 years of both sexes were included in this study. They were started on indigenous CPAP through flow inflating device on clinical grounds based on the pediatric assessment triangle, and the duration and outcome were analyzed. RESULTS: This study population included 214 children. CPAP through flow inflating device was successful in 89.7% of cases, of which bronchiolitis accounted for 98.3%. A prolonged duration of CPAP support of >96 h was required in pneumonia. CPAP failure was noted in 10.3% of cases, the major risk factors being children <1 year and pneumonia with septic shock. CONCLUSION: We conclude that flow inflating devices - JR/Bain circuit are effective as an indigenous CPAP in limited resource settings. Despite its benefits, CPAP is not a substitute for invasive ventilation, as when the need for intubation arises timely intervention is needed.

Vulval Microglandular Adenosis-like Neoplasm With Chondromyxoid Stroma: Report of a Unique Case.

Microglandular adenosis of the breast is an uncommon lesion which can mimic tubular carcinoma. It is composed of small round tubules lined by a single layer of flat or cuboidal epithelial cells, often with eosinophilic colloid-like material within the lumen. The absence of a myoepithelial cell layer and preservation of basement membrane around the tubules are characteristic features. We report the first case of a vulval "neoplasm" in a 60-yr-old woman showing features identical to microglandular adenosis of the breast except for the presence of an unusual chondromyxoid stroma. This case reinforces the analogy between vulval lesions derived from anogenital mammary-like glands and breast lesions and also adds a new entity to the list of lesions arising from these glands.

Value added products with popular low grade rice varieties of Andhra Pradesh.

Eight Popular Low Grade Rice Varieties (PLRVs) MTU 3626, MTU 1001, MTU 1010, MTU 4870 and NLR 145, NLR 34242, NLR 30491, NLR 34449, (developed and released by ANGR agricultural University, Andhra Pradesh) having poor cooking quality were selected for the study. ANGRAU variety BPT 5204 popularly consumed as staple rice was used as check. Eight products of traditional/commercial importance were standardized incorporating PLRVs as a major ingredient in the form of rice flour (burfi, noodles and extruded snack product and vennaundalu (butter coated balls), palathalikalu (dough rolled into strips, steamed/cooked in milk); rice semolina (instant kheer mix and instant upma mix), and flaked rice (nutritious bar). The products were evaluated for nutritional, cooking quality characteristics, consumer acceptability and shelf-life. Consumer acceptability of the PLR products was carried out with 60 farm women based on 9 point hedonic scale. Shelf-life of the products (packed in both metalized PP and PE pouches) was evaluated monthly for chemical, microbiological and sensory parameters. Energy values of control and PLR products showed no significant difference. Upon cooking, PLR Noodles showed no significant difference with water absorption and volume but more (p < 0.05) solid loss and cooked weight. Utilization of PLR flakes in nutritious bar resulted in highly crispy and crunchy texture, enhanced flavor and taste as compared to control. The percent total solids and suspended solids were more (though not significant) in PLR kheer and palathalikalu. Extruded product (control and PLR) showed no significant difference with length, diameter, weight and volume expansion ratio and water absorption index (WAI). Consumer acceptability was high for PLR products palathalikalu (95%), instant kheer mix (92%) and extruded product (88%). As per sensory scores, all the PLR products were well accepted with no observable changes in flavor or taste upon storage. PLR products showed increased (P < 0.05) trend for moisture and FFA content from initial to 90 days of storage. The lowest TPC was observed for noodles and highest for burfi (though in safe limits). Extruded snacks (control and PLR) showed no microbial growth during the entire storage period. Considering the poor marketability of PLRVs for consumption as staple rice, the study signifies the utilitarian value of PLRVs in making products of convenience/commercial importance.

Isolation and characterization of fluorescent pseudomonads and their effect on plant growth promotion.

Seven isolates of fluorescent pseudomonads were evaluated for their effect on plant growth promoting traits, both under normal and saline conditions using tomato plants. Fifteen rhizosphere samples from crop fields' of rice, chilly, ragi, beans and garden soils from different regions of India were collected and used for further study. They were characterized morphologically and biochemically which led to a conclusion that they may belong to genus Pseudomonas. They were also analyzed for their plant growth promoting activities such as production of indole acetic acid, siderophore, hydrogen cyanide and ammonia. It was observed that all the isolates were able to produce these compounds, but to varying extent. But, isolate JUPF37 produced highest followed by JUPF32. Study showed that out of seven isolates of fluorescent pseudomonads, JUPF37 showed highest plant growth promoting traits both under normal and saline conditions.

Comparative evaluation of levels of C-reactive protein and PMN in periodontitis patients related to cardiovascular disease.

BACKGROUND: Numerous cross-sectional studies have suggested that chronic periodontitis is a risk factor for cardiovascular diseases. There is evidence that periodontitis and cardiovascular diseases are linked by inflammatory factors including C-reactive protein. The purpose of the study was to investigate the levels of CRP and PNM cells as a marker of inflammatory host response in the serum of chronic periodontitis patients and in patients with CVD. MATERIALS AND METHODS: Study population included 75 patients; both male and female above 35 years were included for the study. The patients were divided into three groups of 25 each - Group I: Chronic periodontitis patients with CVD, Group II: Chronic periodontitis patients without CVD and Group III: Control subjects (without chronic periodontitis and CVD). Patients with chronic periodontitis had ≥8 teeth involved with probing depth (PD) ≥5 mm involved. The control group had PD ≤ 3 mm and no CVD. Venous blood was collected from the patients and C-reactive protein levels were analyzed by immunoturbidimetry. PMN was recorded by differential count method. RESULTS: On comparison, OHI-S Index, GI, mean PD, CRP and PMN values showed significant difference from Group I to III. CRP level was highly significant in Group I when compared with Group II and Group III. PMN level was highly significant in Group I when compared with Group III PMN level which was not significant. CONCLUSION: This study indicated that periodontitis may add the inflammation burden of the individual and may result in increased levels of CVD based on serum CRP levels. Thus, controlled prospective trials with large sample size should be carried out to know the true nature of the relationship if indeed one exists.

Uncommon Peritoneal Anomaly of Spleen Associated with the Unusual Relationship of Spleen with the Left Lobe of the Liver

Though congenital anomalies of the spleen are quite common, the peritoneal anomalies of the spleen are very rare. In the present case, we observed two unusual phrenico-splenic ligaments connecting the spleen to the diaphragm. Apart from this, the left lobe of the liver was elongated and was related to the diaphragmatic surface of the spleen. The splenic artery had a straight course to the spleen, indicating the possible restricted movements of the spleen. Knowledge of such unusual relation of spleen is essentially important for the surgeons as the elongated left lobe of the liver might get ruptured in addition to the spleen in the fractures of the left 9th, 10th and 11th ribs. Awareness of the straight course of the splenic artery is also of importance to Radiologists performing arterial splenoportography.

"Blow-torch phenomenon" during laser assisted excision of a thyroglossal cyst at the base of the tongue.

We report a case of blow-torch phenomenon encountered during diode laser assisted excision of a thyroglossal cyst in a child. This is first such case report from India and highlights an unusual complication which anesthesiologists need to be aware of due to the increasing use of operative laser.

Mandibular symphysis graft versus iliac cortical graft in reconstructing floor in orbital blow out fracture: A comparative study.

AIM: The purpose of this study was to clinically and radiologically assess and compare the outcome of internal orbital reconstruction with an iliac bone graft and mandibular symphysis graft in orbital blow out fractures. MATERIALS AND METHODS: Eight consecutive patients with unilateral orbital blow out fractures were enrolled in this prospective study. CT scan imaging and volumetric assessment of the orbit was done for all patients using GE Discovery VCT Workstation 4.4. Patients with defect of area less than 2 cm(2) and orbital volume expansion of less than 4.7 cm(3) were treated with mandibular symphysis graft, in contrast the others were treated with a medial cortical graft from the anterior ilium. At each follow-up visit, globe posture, diplopia, and eye movements were assessed. Coronal and sagittal computed tomography and volumetric assessment were used to observe graft posture, bone defects and contour. RESULTS: Group I cases showed that orbital volume changes of less than 2cm(3) can be effectively reduced. Group II cases showed that orbital volume changes of more than 4.5 cm(3) could not be effectively restored in spite of using large iliac graft. All eight patients had satisfactory correction of hypoglobus. Diplopia and ocular motility restriction resolved in all affected patients post operatively between 4(th) day and 2(nd) week. At 3-month follow-up, computed tomography demonstrated that the middle section of the orbital floor was well elevated in all 8 orbits. All grafts were still in situ, with density measured in Hounsfield units revealed that the Mandible Symphyseal graft was denser. CONCLUSION: The mandibular symphysis graft is a good, simple reconstructive option in small orbital floor defects with orbital volume change less than 4.71 ml. In larger defects with huge orbital volume changes that require more volume of graft, iliac graft is useful albeit, perfect, volumetric restoration is not always possible.
