Publisher Copyright: © 2023 The Authors A successful attempt has been made to improve the mechanical properties of Hydroxyapatite (HAp) and reduced graphene oxide (rGO) composite nanoparticles (NPs). Various proportions of HAp and rGO were synthesized to improve the mechanical properties. HAp NPs were prepared using the wet precipitation method and further calcined to form crystalline particles. The physicochemical characterization of the HAp NPs revealed that the crystalline size and percentage of crystallinity were calculated to be 42.49 ± 1.2 nm and 44% post calcination. Furthermore, the rGO-HA composites were prepared using ball milling and obtained in the shape of pellets with different ratios of rGO (10, 20, 30, 40, 50% wt.). The mechanical properties have been evaluated through a Universal testing machine. Compared to calcined HAp (cHAp), the strength of variants significantly enhanced with the increased concentration of rGO. The compressive strength of HA-rGO with the ratio of the concentration of 60:40% by weight is a maximum of about 10.39 ± 0.43 MPa. However, the porosity has also been bolstered by increasing the concentration of rGO, which has been evaluated through the liquid displacement method. The mean surface roughness of the composites has also been evaluated from the images through Image J (an image analysis program).

Background: There is an increasing evidence for the use of thin flaps based on vascular perforators for reconstructive surgeries. The medial sural and deep inferior epigastric artery flaps offer versatility for the reconstruction of major defects of the head and neck. Objectives: “Whether medial sural artery perforator (MSAP) flap or rectus abdominis perforator flap is better for the reconstruction of glossectomy defects in terms of functional outcome?” Data Sources: PubMed, Cochrane Library, clinicaltrials.gov and hand searches. Participants and Interventions: Patients who underwent tongue reconstruction with either MSAP flap or deep inferior epigastric artery perforator (DIEAP) flap. Study Appraisal and Synthesis Methods: Based on defined study criteria 6 studies were selected according to Prisma Guidelines. The overall estimated effect was categorized as significant where P < 0.05. Results: There was no significant difference between both flaps in terms of receptor site complications (P = 0.223). Overall odds ratio (OR) for complications was 1.35 (95% confidence interval [CI]: 0.412–0.736) and the test for overall effect t value was 2.836, P < 0.05. Overall OR was 6.01 (95% CI 0.5–7.45) and the test for overall effect t value was 1.41, P < 0.05 indicating there was a statistical difference in the intelligibility of speech. Limitations: Anatomical variations, under-reporting of studies and lack of universal tool for speech intelligibility. Conclusions and Implications of Key Findings: Both the flaps are comparable in terms of functional outcome. Medium-sized defects can be reconstructed with MSAP and composite larger defects would benefit from DIEAP. In females, anterolateral thigh flap still remains the choice for composite reconstructions.

BACKGROUND: Trapdoor fractures commonly occur in children below 6 years of age. The high resiliency of bone, pneumatisation of sinuses and other factors lead to entrapment of muscle and/or soft tissue which undergoes ischaemic changes leading to residual diplopia. The timing of intervention in children ranges from 24 h to greater than 2 weeks. Early surgical intervention is particularly indicated in cases of Oculocardiac reflex. METHODS: A Prisma guided systematic review of literature was conducted with no filters on language till September 2020. Studies on paediatric orbital fractures with data on timing of intervention and clinical outcomes were considered eligible for the review. The Oxford Level Of Evidence was used to assess the strength of individual studies. RESULTS: A total of 19 studies (18 English, 1 French) were selected; except for one study all were retrospective series. The timing of intervention ranged from 24 h to more than 1 month. Most of the studies agreed that orbital fractures in children should receive early intervention preferably within 2 weeks. In case of white-eyed blowout fracture, oculocardiac reflex and trapdoor fractures with muscle entrapment surgical intervention should be carried out within 24–48 h. DISCUSSION: Children presenting with facial injuries should be thoroughly examined for signs of muscle entrapment, diplopia, nausea, vomiting and bradycardia. If present these should receive early intervention. In cases with no signs of oculocardiac reflex and muscle entrapment a treatment within 2 weeks is recommended. If diplopia is mild or resolving with minimal hypoglobus and enophthalmos a wait and watch policy should be carried out.

Introduction: The incidence of recurrence of OKC varied from 2.5%-62%. Studies have linked recurrence to treatment methods and also clinical and pathological features. The aim of this study was to evaluate the 5 year recurrence and the factors associated with recurrence in odontogenic keratocysts of the jaws.Methods: A retrospective review of records was done from the Institute’s Medical Records Directory from 2010-2021. The following data were obtained of the lesion; age at presentation, gender, site, subsite, radiographic presentation (locularity), radiographic borders, presence or absence of satellite cysts, inflammatory infiltrate, and treatment rendered presence or absence of cortical perforation and soft tissue extension and presence or absence of recurrence. Kaplan Meir estimator was used to evaluate recurrence rate and log rank test was used to compare the survival amongst groups. Cox regression analysis was used to evaluate the odds ratio to find out the possible factors influencing risk of recurrence. A p value of

A cross-sectional study was conducted to assess the utility of online teaching for general surgery postgraduate residents at the end of 1 month of online teaching during the COVID-19 lockdown. A questionnaire related to different aspects of online teaching was developed on a 5-point Likert scale from “strongly agree” to “strongly disagree”. Following a pilot study, the questionnaire was shared among surgery residents, and response collection was done. The residents who did not attend at least 90% of scheduled classes were excluded. A total of 55 resident doctors without prior experience of online teaching program were enrolled in the study. All the participants responded to all questions and submitted their responses within stipulated time. On the basis of validity testing, questions 1 and 2 were found invalid and hence deleted. The median value for the total cohort was 4 indicating that majority of residents gave affirmative response. On segregating the result with the year of residency program, similar results were found in the 1st year and 2nd year group; however, the 3rd year group showed a median of 3, thus eliciting that only 50% of 3rd year residents liked online teaching. From the present study, it can be concluded that the online teaching is a feasible alternative to the physical class among surgical postgraduates. The questionnaire utilized in the present study can be used for assessing similar online teaching protocols.

The aim of this research study to identify the role of empathy,moral judgement and social entrepreneurial education in predicting social entrepreneurial intention. And also test the mediating effect of prosocial motivation in this relationship. Through the survey, primary sample data of 755 nascent social entrepreneurs were used to test the hypotheses. The hypothesised moderated mediation condition was supported as results suggest that prosocial motivation mediated the relationship between antecedents and social entrepreneurial intentions. Besides this social entrepreneurial education showed a strong direct relationship with social entrepreneurial intentions. These findings strengthen the argument which states that there is a great need from policy, educators and universities to start courses that can imbibe the feeling of empathy. And also support system to motivates students to go for social entrepreneurship as a career choice.

Introduction Preoperative imaging is a standard practice for cochlear implant candidacy. We are discussing association between surgical feasibility and various anatomical details of middle and inner ear by both high-resolution computed tomography (HRCT) and 3T magnetic resonance imaging (MRI) in patients with bilateral sensorineural hearing loss (SNHL) and are used as a guide during surgery as well as foresee complications in cochlear implantation. Materials and Methods A total of 56 patients of aged 1 to 5 years (prelingual) and > 1 years (postlingual or perilingual) having bilateral SNHL were included in the study. HRCT temporal bone and MRI head was done in all candidates. Based on the imaging findings of CT and MRI, patients were divided into two categories (normal and abnormal). Demographic and clinical values were compared between two groups. Binary logistic regression analysis was used to identify the predictors of the outcome variable (surgical difficulty). Results Out of 56 patients, 55 underwent cochlear implantation by Veria technique, one patient having Michel’s deformity was denied surgery and was advised brain stem implant. Note that 69.1% patients had no radiological abnormality, while 30.9% patients showed abnormality including acquired disease and malformation. Out of the total study patients, 18% (n = 10) showed various type of congenital inner ear malformation. Large size of the external auditory canal (EAC), high basal turn angle (BTA), and increased distance between tympanic segment of facial canal to EAC (midpoint between level of I-S joint corresponding to EAC and exit of chordae tympanic at level of EAC), all these factors showed inverse relationship with difficulty in surgery, which were found to be statistically significant. Conclusion The imaging in cochlear implant patients is an essential tool for preoperative assessment of candidacy, surgical planning, and avoid intra- and postoperative complications. BTA and distance between tympanic segment of facial nerve and EAC (midpoint between level of I-S joint corresponding to EAC and exit of chordae tympanic at level of EAC) are important predictors for evaluating intra- and postoperative complications.

As propranolol has emerged as first-line therapy for problematic infantile hemangioma, the number of non-responders and partial responders to propranolol therapy is also increasing.The study was conducted to evaluate the response of intralesional bleomycin, triamcinolone, and a combination of both as second line of treatment for the residual hemangioma following propranolol therapy.A prospective comparative study was conducted in patients who were either non-responders or partial responders to previous propranolol treatment.The patients randomly received injection bleomycin, injection triamcinolone, and combination of both bleomycin and triamcinolone. The response to treatment was recorded clinically by using photographs. The pathological response was assessed by calculating pre-treatment and post-treatment microvessel density in biopsy of lesion from the non-cosmetic sites using immunohistochemistry.χOut of the 134 patients, 42 received bleomycin and 44 received triamcinolone and were treated with a combination of both. The overall clinical response was better in the combination group compared with the bleomycin group (The combination of bleomycin and triamcinolone is effective and safe for the treatment of residual hemangioma.

To assess the adverse effects of propranolol therapy in infantile hemangioma. An ambispective study was conducted from August 2011 to December 2019. In retrospective arm all children managed for infantile hemangioma with propranolol were included and case records were assessed for adverse reactions. In prospective arm the adverse reactions were identified on the basis of predefined criteria. A total of 514 patients (358 retrospective records) were included. A majority, 378 (73.5%) patients had an excellent response, 75 (14.5%) had partial response and 61 (11.8 %) had no response. A total of 82 (15.9%) patients experienced at least one adverse effect. Diarrhea with weight loss (27, 32.9%) and irritability with decreased sleep (21, 25.6%) were the most common adverse effects. The adverse effects in 22 (4.2%) cases lead to the discontinuation of propranolol. Younger age, low body weight and early onset were risk factors for development of severe adverse reactions. Young children with low body weight were at higher risk for adverse effects of propranolol.

Propranolol has emerged as a first line agent in the management of hemangiomas. With increased use of propranolol, studies have also focused on relapses following propranolol therapy. Our current study evaluates the role of bleomycin triamcinolone sclerotherapy for the management of propranolol resistant Infantile Hemangioma (IH). We also evaluated the role color Doppler USG for response assessment of sclerotherapy.Patients with Propranolol resistant (Non- responders/ Partial responders) IHs were included in the study. Patients received intralesional bleomycin at a dose of 0.5 IU/kg followed by intralesional injection of triamcinolone at a dose of 2mg/kg body weight. Clinically patients were grouped into excellent, partial and non responders. Doppler parameters; Resistivity index (RI), Pulsatility index(PI) and Peak systolic velocity (PSV) were used to evaluate the response to sclerotherapy. These parameters were evaluated prior to sclerotherapy and 3 months following completion of therapy. The clinical responses of the patients were compared with the change in Doppler parameters before and after treatment.A total of 115 participants were considered for analysis; 60.86% had excellent response, 32.17% had partial response and 6.95% had poor response. There was a significant change in terms of RI, PI and PSV in patients who were either excellent or partial responders. Poor responders did not have a significant change in Doppler parameters.Combined bleomycin- triamcinolone sclerotherapy is an effective therapy for the management of propranolol resistant IHs. Doppler parameters RI, PI and PSV are reliable indicators of response in the management of IH.

Study Design PRISMA-SWiM guided systematic review. Objective 1. Provide consistent evidence regarding the management of atrophic mandible fractures; 2. To search, evaluate and validate existing guidelines if any for the management; 3. Provide evidence regarding specific management of condylar fractures in the atrophic mandible; 4. To address the clinical applicability of bone grafts. Methods A systematic review was conducted using the PRISMA-SWiM protocol. PROSPERO ID: CRD42021235111. Studies with adequate data on outcome, treatment methods were selected. Isolated case reports, case series, and non-human studies were excluded. Quality assessment was done using Newcastle -Ottawa scale. The level of evidence was assessed using Oxford Level of Evidence. Results Mandibular body was the most common type of fracture. Self falls and RTA were the most common etiologies. Condylar fracture was most commonly managed conservatively with ORIF employed in few studies. For the mandible compression and non-compression osteosynthesis were used. Bone grafts were used in cases with segmental defects or cases requiring augmentation. Conclusions There is lack of proper evidence to definitely conclude any single treatment modality. However, the consensus is towards ORIF. Reconstruction plates are preferred by many authors. However, unilateral fractures may be managed by miniplates. Bilateral fractures require more rigid fixations. Open reduction and internal fixation of condylar fracture is indicated in cases with displacement or low-level fractures.

Propranolol has evolved as a first line management of infantile haemangiomas. Nevertheless, the resistance to propranolol has warranted alternative treatment modalities. We hypothesize that combination of medical and surgical therapy (sandwich therapy) to be beneficial in the management.Patients were divided into three groups (total=31), Group A (bleomycin sclerotherapy), Group B (surgical group), Group C (sandwich therapy). A p valuelt;0.05 was taken as significant.In Group A 54.5% of patients had excellent response, 27.3% partial response and 18.2% had no response. Comparing cosmetic outcome, 25% of patients in Group B and 16.7% of patients in Group C had excellent upshot. On the contrary 18.2% of patients in bleomycin had unsatisfactory and 18.2% had poor cosmetic outcome. Sandwich therapy was cosmetically more acceptable than Bleomycin sclerotherapy (p- value = 0.049). In terms of recurrence, sandwich therapy differed significantly from surgical therapy with fewer recurrences (p-value= 0.049).Sandwich therapy is superior to bleomycin sclerotherapy in terms of cosmetic outcome and has fewer recurrences compared to surgical group and requires single stage resection. However, further studies with the help of Doppler ultrasound are required in this regard.

Lymphangioma of the tongue is a rare lymphatic malformation, and various authors have reported the successful use of sirolimus for its treatment. However, the safety of sirolimus in children needs further evaluation so that those who do not respond are not necessarily exposed to its potential adverse effects. We hypothesised that assessment of lymphangiogenesis can be used to predict whether the patient will respond to sirolimus, so we organised a prospective study after ethics committee approval had been given. After clinical and histological diagnoses of lymphangioma of the tongue had been confirmed, 16 patients were given sirolimus 0.8mg/day in three divided doses. Clinical response was assessed and compared with lymphatic microvessel density (LMVD), which was calculated immunohistochemically using the monoclonal antibody D2-40 as the lymphatic endothelial marker. Nine patients responded well, five partially, and two failed to respond. Mean (SD) LVD among the good responders was 21.00 (3.74), whereas among non-responders it was 8.00 (4.24). There was a significant difference in mean LVD between good responders, partial responders, and non-responders (p=0.04). Sirolimus is effective in treating children with lymphangioma of the tongue, and lymphangiogenesis is a useful therapeutic predictive marker.

Herein, we have reported the exfoliation of laponite (L) in the presence of carboxymethyl cellulose (CMC) and the formation of CMC–laponite (CMC–L) nanocomposite gel. Analysis of CMC–L complex using XRD confirmed that the addition of CMC actually exfoliates laponites. The interplanar spacing of laponite was observed to increase from 0.74 to 0.98 nm when concentration of CMC, CCMC, increased from 0 to 0.5% w/v in aqueous solution of laponite having concentration of laponite, CL = 1% w/v. Time-dependent scattering intensity studied by dynamic light scattering on CMC–L complex (CCMC = 0.5% w/v, CL = 1% w/v) in aqueous medium illustrated that the exfoliation progresses with the passage of time. It was further observed that the CMC–L complex (CL = 1% w/v, CCMC ≥ 0.5% w/v) forms gel, and the strength of gel increases with the increase in CMC concentration in aqueous medium owing to interaction between exfoliated laponite and CMC. Furthermore, microstructure of the gels and their mesh size were studied using small-angle neutron scattering (SANS). SANS study revealed the fact that with the increase in CCMC from 0.5 to 2% w/v in CMC–L gels, mesh size, ξ decreases from 0.29 to 0.24 nm. This decrease in mesh size is responsible for sustained drug release of methylene blue which was chosen as a cationic model drug. The obtained drug release profile was fitted with different release kinetic models, and it was found that release profile follow first-order kinetic model.

Purpose The purpose of this paper is to identify the entrepreneurial intention (EI) among nascent entrepreneurs in the Indian context by using Shapero’s theory of entrepreneurial event as the research framework. Design/methodology/approach A 34-item questionnaire was responded to 250 nascent entrepreneurs who are engaged in executing the new business idea or creating new ventures and enroled in the universities in India. The questions measured perceived desirability, perceived feasibility, entrepreneurial educational background, entrepreneurial self-efficacy, perceived social pressure and previous work experience in entrepreneurial activities towards entrepreneurship intention. The data were collected by employing a systematic random sampling method. The sample represents 174 male and 76 female nascent entrepreneurs belonging to various disciplines. Structural equation modelling has been used for data analysis. Findings The results show that the proposed model in the present study explains 51 per cent of the variance, explaining the entrepreneurship intention. Entrepreneurial self-efficacy was found to be the strongest predictor of EI (β=0.397 at pβ=0.285 at p Research limitations/implications More than limitation this research study adds to the existing literature of the EI by using a different set of the sample. Mostly EI studies used student sample to measure intentions. Kolvereid and Isaksen used a sample of entrepreneurs to measure EI and achieved very different results. Therefore, this research study extends the work of Kolvereid and Isaksen by using a sample of nascent social entrepreneurs. Practical implications The finding of this research study will facilitate policy makers and educators to promote entrepreneurial activities at the university level. Based on the results and findings of the study, the educators may improve upon the support system to help and motivate students to opt for social entrepreneurship as their career choice. Originality/value Ajzen (1988) emphasised that the relative significance of the antecedents of intention will vary depending on which stage of intention is under scrutiny. This is one of its kinds of research study that used a sample of nascent entrepreneurs in the Indian context. Findings of this research will be helpful in predicting how the intention process of nascent entrepreneurs works especially in developing countries.

Main limitation of classical technique is limited access to cochlea in terms of cochlear rotations and related structures, thus causing difficulty in electrode insertion. Veria technique allows full access to cochlea after raising tympanomeatal flap. To our best knowledge this is first clinic-radiological study for Veria technique studying distance between tympanic segment of facial nerve and posterior wall of external auditory canal (EAC) demonstrating facial nerve safety. Prospective study was done on 50 patients having bilateral sensori-neural hearing loss. Patients underwent cochlear implant surgery irrespective of age and gender. Preoperative high-resolution computed tomography temporal bone and magnetic resonance imaging head was done, distance between tympanic segment of facial nerve and posterior wall of EAC and basal turn angle were measured. Intraoperative NRT followed by orbito-meatal X-ray was done in post operative period. 25 (50%) were male, 25 (50%) female. 35 patients (70%) showed that the distance between tympanic segment of facial nerve and posterior wall of EAC was more than 3 mm with mean 4.41 mm (± 0.63 SD). Distance calculated was greater in older age group than younger group. Patient having inner ear malformation, mean was 3.96 mm (± .44 SD). Whereas patients having acquired disease, mean distance was 4.30 mm (± .47 SD). On gender comparison of basal turn angle score, no significant difference was observed male (54.34° ± 4.48°) versus female (55.66° ± 4.15°) (p = 0.282). Mean of basal turn angle (BTA) in ≤ 5 years age group was 54.89° ± 3.65°, in 6–10 years age group was 55.21° ± 5.23° and in age group ≥ 11 years was 54.93° ± 4° with no significant difference in mean value between the groups (p = 0.282). High jugular bulb was seen in 4 patients (2 in right side, 2 in left side), hypoplastic jugular bulb was seen in 10 patients (9 in left, 1 in right), otosclerosis in 2 patients. Veria technique is safe for facial nerve, as preoperatively distance between tympanic segment of facial nerve and posterior canal wall can be identified. It is suitable method for rotated cochlea (identified preoperatively through BTA) and deformed cochlea as it offers a wide visibility and accessibility as compared to posterior tympanotomy approach. BTA and distance between posterior canal wall of EAC and tympanic segment of facial nerve should be done in all cases to see any cochlear rotation and feasibility of surgery.

Adenomatous hyperplasia of the salivary glands usually affects the parotid gland. Within the oral cavity, palate is the most common site. However, this lesion occurs in adults and till date no case has been documented in neonates. Angiolipomas are a variant of congenital lipomas which undergoes vascular proliferation. Angiolipomas of the oral cavity have not been documented till date among neonates. We herein report the first case of combined angiolipoma of the floor of the mouth with adenomatous proliferation of the minor salivary glands in a neonate. The case was managed through surgical excision, and the follow-up was uneventful. Histopathology confirmed the diagnosis.

Osteomyelitis is an inflammatory infectious disease that affects bone and bone marrow. Histopathology remains the gold standard method for diagnosis, but imaging modalities also play an important role. We systematically reviewed five articles with comparative studies on plain films, computed tomography (CT) scan, magnetic resonance imaging (MRI), cone beam computed tomography (CBCT), positron emission tomography (PET), single photon-emission computed tomography (SPECT), scintigraphy, and SPECT/CT. Scintigraphy and SPECT/CT has the highest sensitivity of 100%. PET is only to be used in cases of follow up. Orthopantomography (OPG) is the most common initial diagnostic tool despite its low sensitivity. CT provides the necessary specificity needed for radionuclide imaging, which has the highest negative predictive value of 100% and a positive predictive value >95%. SPECT/CT with 100% sensitivity and 85% specificity can be considered as the imaging modality of choice for initial diagnosis and follow up.

Different techniques of the management of sagittal maxillary fractures have been described with different advantages and disadvantages. We herein present our experience and results of managing these cases by reversing pre-activated maxillary expanders and evaluation of its efficacy. A prospective study was conducted from April 2016 to February 2020 including all the patients managed for sagittal palatal fractures using the modified technique. The patients were evaluated for healing, occlusion and complications. A total of five patients with sagittal palatal fracture were managed. The mean Glasgow Coma (GCS) score and injury severity score (ISS) of patients were 11.6 ± 2.4 and 15.2 ± 4.3, respectively. Both had a significant strong negative correlation with a correlation coefficient of − 0.889 (p = 0.44). The median duration for initiating the treatment for facial fractures was 2 days (range 2–12 days). All patients achieved satisfactory outcomes and tolerated this technique well. No obvious complications were found. This method could produce enough transversal force to reduce fractured fragments and then serve as an external fixator to maintain stability for bony healing.

Prunus dulcis (almond) is one of the most commonly ingested dry fruits by peoples in their routine diet plan due to its high nutrition content. However, almond peels are not eaten and thrown as a waste material. The reason is that the peels are not easily digested in human body due to its low solubility in aqueous medium. Also, the peels contain low amount of cyanides. Surprisingly, almond peels also contain various active bio-compounds which have not been explored properly for any industrial purpose. With the idea of utilizing a waste material and checking solution dependability, the aqueous and methanolic extracts of almond peels have been prepared and investigated by experimental techniques and theoretical tools. The protection efficiency of the extracts in reduction of mild steel (MS) dissolution in 0.1 M HCl has been determined by electrochemical methods (impedance analysis and polarization behavior). The results shows that methanolic and aqueous extracts avert 93% and 85% mild steel loss respectively, which portray that methanolic extract is more effective than aqueous extract. This fact is supported by the surface analysis of mild steel samples done by HRSEM and AFM. UV–vis and FTIR spectroscopy analysis reveals the reason that methanol can extract more phytochemcial constituents of almond peels than water. The free energies of adsorption (ΔG°) for both extract's molecules have been determined based on adsorption coefficient (Kads) obtained from Langmuir isotherm fitting of inhibition data, which suggest that adsorption is neither pure physical nor pure chemical, i.e., mixed type. DFT modeling and Monte carlo simulation techniques are also explored to investigate theoretical adsorption and inhibition characteristics of the molecules, which supports the interpretation of the experimental results.

Psoriatic arthritis (PsA) is associated with increased cardiovascular morbidity and mortality. Higher disease activity has been associated with increased rates of mortality in PsA. The objectives of the study were to describe the trends for hospitalisations from acute myocardial infarction (AMI) amongst patients with underlying PsA.All adult hospitalisations for AMI with and without PsA from 2004-2014 in the nationwide in-patient sample (NIS) database were captured. A propensity score-matching model was also developed for comparative outcome analysis and reduce the potential of selection bias.From 2004 to 2014, 4778 unmatched weighted hospitalisations were estimated for AMI with underlying PsA. Mean age for hospitalisations with AMI and PsA was lower (average age in years: 63.1±11.5 vs. 67.5±14.4; p-value0.05), with a higher percentage being males (62.7% vs. 60.4%, p-value0.05). When adjusted for confounding factors, overall mortality was found to be signi cantly lower in hospitalisations with PsA (2.21% vs. 5.8%, p-value0.05). After propensity matching analyses, in-hospital mortality in PsA cohort continued to be signi cantly lower when compared to the matched cohort without PsA (1.79% vs. 5.71%, Odds ratio=0.3, p-value 0.002).The study suggests that overall rates of mortality in AMI with underlying PsA are lower compared to those without PsA. A decrease in cardiovascular mortality from AMI in PsA re ects that even though PsA is associated with an increased prevalence of cardiovascular risk factors, the trends in mortality are similar or even better than those for the general population.

Geospatial information, including satellite information, is a vital part of crop yield prediction since it can give normal, predictable, target data. Distinguishing geospatial designs and measure changes that happen require exceptional systems to be used. Different monetary and organic variables impact the yield production and variables prompt losses to farmers. These dangers can be evaluated when proper numerical or measurable strategies are connected with soil, climate and past yield data. This article reviews different models utilized for crop yield forecasting. The focus of this problem is the increasing size of the data. Here, various approaches adopted by researchers are detailed with their field of accuracy for prediction. Some of issues related to the papers are also discussed. The techniques of knowledge extraction and storage were also discussed in this work.
