A Displasia Ectodérmica (DE) é uma desordem genética rara que afeta cabelos, pêlos, unhas e dentes, resultando em manifestações orais significativas, geralmente percebidas na infância.  O objetivo deste trabalho foi revisar na literatura a atuação do cirurgião-dentista frente à DE em pacientes pediátricos. Tratou-se de uma revisão integrativa de literatura, descritiva, com abordagem qualitativa, realizada no período de agosto de 2020 a maio de 2021, no portal da Biblioteca Virtual em Saúde (BVS), Scielo e Pubmed, sendo selecionados 18 artigos do tipo relato de caso. A média de idade dos pacientes dos estudos variou entre 2 a 14 anos. As manifestações intraorais comumente encontradas foram a hipodontia e oligodontia, seguidas de alterações morfólogicas, enquanto que a anodontia foi considerada rara em casos de DE. O grau de complexidade da síndrome e a manifestação dos sintomas irão ditar a escolha do tratamento, que pode variar entre as resinas compostas, ortodontia e próteses parciais fixas ou remomíveis e totais. A atuação do cirurgião-dentista desde o diagnóstico até a reabilitação definitiva auxilia o paciente em seu amplo aspecto biopsicossocial, reduzindo, portanto, os impactos negativos na qualidade de vida dos individuos afetados.

A Pneumonia Associada à Ventilação Mecânica (PAVM) consiste na infecção respiratória mais comum nas Unidades de Terapia Intensiva (UTIs), surgindo no período entre 48-72 horas após a intubação orotraqueal e a instalação da ventilação mecânica (VM). O objetivo deste estudo foi revisar fundamentos teóricos sobre a atuação do cirurgião-dentista (CD) na prevenção da PAVM. Tratou-se de uma revisão integrativa de literatura, com abordagem qualitativa, realizada no período de fevereiro a outubro de 2021 nos portais Google Acadêmico, Scientific Electronic Library Online (Scielo), PubMed e Biblioteca Virtual em Saúde (BVS), através dos descritores: ‘‘Cirurgião-dentista’’, ‘‘Pneumonia Associada à Ventilação Mecânica’’, ‘‘Odontologia’’, ‘‘COVID-19’’, ‘‘Pandemias’’, ‘‘Infecções nosocomiais’’, ''Dentist'', ‘‘Pneumonia, Ventilator-Associated’’, ''Dentistry'', ''COVID-19'', ''Pandemics'' e “Nosocomial Infenctions” previamente consultados no Descritores em Ciências da Saúde (DeCS) e no Medical Subject Headings (MeSH), sendo selecionados 26 artigos para síntese. Mediante a análise bibliográfica, 12 estudos dos tipos observacionais e experimentais constataram a redução dos índices de PAVM através da implementação de protocolos de higiene oral com digluconato de clorexidina a 0,12%, associados ou não, a escovação mecânica. Além disso, foi percebido que pacientes diagnosticados com COVID-19 e submetidos à VM, apresentaram maior predisposição para desenvolver a PAVM. Assim, a inclusão do CD na equipe hospitalar permite a implementação de protocolos preventivos padronizados que reduzem consideravelmente a incidência da enfermidade.
Non-Hermitian mosaic dimerized lattices

Published: June 2022

Non-Hermitian systems have attracted much attention during the past few years, both theoretically and experimentally. The existence of non-Hermiticity can induce multiple exotic phenomena that cannot be observed in Hermitian systems. In this work, we introduce a new non-Hermitian system called the non-Hermitian mosaic dimerized lattice. Unlike the regular nonreciprocal lattices where asymmetric hoppings are imposed on every hopping term, here in the mosaic dimerized lattices the staggered asymmetric hoppings are only added to the nearest-neighboring hopping terms with equally spaced sites. By investigating the energy spectra, the non-Hermitian skin effect (NHSE), and the topological phases in such lattice models, we find that the period of the mosaic asymmetric hopping can influence the system’s properties significantly. For a system with real system parameters, we find that as the strength of asymmetric hopping increases, the energy spectra of the system under open boundary conditions will undergo a real-imaginary or real-complex transition. As to the NHSE, we find that when the period is odd, there appears no NHSE in the system and the spectra under open boundary conditions (OBCs) and periodic boundary conditions (PBCs) are the same (except for the topological edge modes under OBCs). If the period of the mosaic asymmetric hopping is even, the NHSE will emerge and the spectra under different boundary conditions exhibit distinctive structures. The PBC spectra form loop structures, indicating the existence of point gaps that are absent in the spectra under OBCs. The point gap in the PBC spectrum is shown to be the topological origin of the NHSE under OBCs, which also explains the NHSE in our mosaic dimerized lattices. To distinguish whether the bulk states of the system under OBCs are shifted to the left or right end of the one-dimensional lattice due to the NHSE, we define a new variable called the directional inverse participation ratio (dIPR). The positive dIPR indicates that the state is localized at the right end while the negative dIPR corresponds to the states localized at the left end of the one-dimensional lattice. We further study the topological zero-energy edge modes and characterize them by calculating the Berry phases based on the generalized Bloch Hamiltonian method. In addition, we also find that the topological edge modes with nonzero but constant energy can exist in the system. Our work provides a new non-Hermitian lattice model and unveils the exotic effect of mosaic asymmetric hopping on the properties of non-Hermitian systems.

Published: June 2022

Sleep strongly affects synaptic strength, making it critical for cognition, especially learning and memory formation. Whether and how sleep deprivation modulates human brain physiology and cognition is not well understood. Here we examined how overnight sleep deprivation vs overnight sufficient sleep affects (a) cortical excitability, measured by transcranial magnetic stimulation, (b) inducibility of long-term potentiation (LTP)- and long-term depression (LTD)-like plasticity via transcranial direct current stimulation (tDCS), and (c) learning, memory, and attention. The results suggest that sleep deprivation upscales cortical excitability due to enhanced glutamate-related cortical facilitation and decreases and/or reverses GABAergic cortical inhibition. Furthermore, tDCS-induced LTP-like plasticity (anodal) abolishes while the inhibitory LTD-like plasticity (cathodal) converts to excitatory LTP-like plasticity under sleep deprivation. This is associated with increased EEG theta oscillations due to sleep pressure. Finally, we show that learning and memory formation, behavioral counterparts of plasticity, and working memory and attention, which rely on cortical excitability, are impaired during sleep deprivation. Our data indicate that upscaled brain excitability and altered plasticity, due to sleep deprivation, are associated with impaired cognitive performance. Besides showing how brain physiology and cognition undergo changes (from neurophysiology to higher-order cognition) under sleep pressure, the findings have implications for variability and optimal application of noninvasive brain stimulation.

Published: June 2022

Background: Hypertensive disorders of pregnancy (HDP) complicate 10% of pregnancies. They are the main cause of maternal mortality and require a multidisciplinary team to address them. Objectives: The aim of this study was to quantify the prevalence and define the characteristics and outcome of HDP in a center with a program focused on its management. Methods: This was a continuous and prospective registry from November 2019 to July 2021 that included all patients with HDP [chronic hypertension (CHT), gestational hypertension (GHT), early-onset preeclampsia (EPE), late preeclampsia (LPE), superimposed preeclampsia (SIPE) and eclampsia] who met the inclusion criteria. Patients without medical coverage that prevented long-term outpatient follow-up at the institution were excluded. Baseline charact ristics and evolution, treatment and persistent HT after puerperium were evaluated. The incidence of intrauterine growth retardation (IUGR), preterm delivery, maternal mortality and neonatal death within the first 28 days of life was analyzed. Results: Among a total f 5825 deliveries/caesarean sections, 152 patients with GHT (37.5%), EPE (19.7%), LPE (38.8%), SIPE (3.3%), and eclampsia (0.6%) who met the inclusion criteria were included in the study. Mean age was 36.4±5.6 years. Aspirin was administered to 38.1% of patients. The most commonly used antihypertensive drugs were labetalol (65.8%) and enalapril (44.1%) during pregnancy and puerperium, respectively. There was no maternal mortality, and neonatal mortality was 3.6%. Persistent HT was 20.0%. Conclusion: Late preeclampsia was the most frequent HDP in the population analyzed. More than half of the patients who developed HDP did not receive preventive treatment with aspirin, showing a deficit in the identification of the population at risk. One in 5 HDP patients remained with CHTN after puerperium.

Published: June 2022

Introduction: Tympanoplasty is the surgery performed in Chronic Otitis Media (COM) to improve the hearing function and prevent ear discharge. Platelet Rich Fibrin (PRF) is one of the materials that can be used to improve the graft uptake and hearing outcome. It is obtained by centrifugation of blood. The PRF contains leukocytes, cytokines, structural glycoproteins and growth factors which accelerates healing. It has been used in various surgical procedures to improve the outcome. Aim: To determine the efficacy of autologous PRF in closure of tympanic membrane perforation after tympanoplasty and to study the influence of PRF on the hearing outcome in the study population. Materials and Methods: This prospective interventional study was conducted in Department of Ear, Nose and Throat at SDM Medical College, Dharwad, Karnataka, India, from November 2018 to June 2020. The study included 60 patients with safe type of COM, who underwent tympanoplasty. Two group were made, group A consisted of 30 consecutive patients with safe type COM who underwent tympanoplasty with PRF application and group B, consisted of 30 patients who underwent tympanoplasty without PRF application. The outcome was assessed by endoscopic evaluation every month for 3 months to look for graft uptake. Hearing gain was evaluated by Pure Tone Audiometry (PTA) after 3 months of surgery. Statistical analysis was done using Chi-square test. Results: Group A had 29 cases with complete tympanic membrane closure and only one failure. However in group B, three out of 30 cases had failure. Thus, the overall the success rate was 96.66% in group A and 90% in group B. Postoperative PTA in group A showed that 18 cases (60%) had an improvement of >15 dB whereas in group B, 12 cases (40%) had hearing improvement of >15 dB. Conclusion: Considering the higher success rate of tympanoplasty with group A compared to group B and no noticeable side effects, it is recommended that tympanoplasty with autologous PRF should be preferred.

Published: June 2022

The stabilization capability of rice husk ash (RHA) and Ordinary Portland cement (OPC) was scrutinized using laboratory scrutiny. Three soils (Soil A, B, and C) were improved with various percentages (via weight of dry soil) at 0, 2, 4, 6, 8, and 10% for all stabilizing agents and compacted via BSL (British Standard light) energy. Their impacts were assessed on the strength physiognomies such as UCS (unconfined compressive strength), OMC (optimum moisture content), California bearing ratio (CBR), and MDD (maximum dry density tests based on ASTM (American Standard Testing Materials) codes. The result reveals the optimum values for three lateritic samples, A, B, and C, illustrated a reduction in plasticity for rice husk ash (RSA) stabilizer from 17.32%, 12.67%, and 19.07% (at 6% cement) to 16.32%, 9.90% and 17.00% (at 6% cement and 6% RHA) respectively. Likewise, the optimum Triaxial test result for RHA at 6% with a specified cement content of 6% are A (Deviation stress 595.45KN/m2, Cohesion 10KN/m2, Angle of internal friction 280, and Shear stress 175.5KN/m2), B (Deviation stress 514.75KN/m2, Cohesion 9KN/m2, Angle of internal friction 280 and Shear stress 168.5KN/m2), and C (Deviation stress   530.58KN/m2, Cohesion 10KN/m2, Angle of internal friction 290 and Shear stress  162.0KN/m2.
Validation of ANSYS Model of Experimental Test Rig Simulating the Flow Inversion in RRs
Authors: Elnaggar Sayed
Published: June 2022

The experimental setup was built to simulate the flow inversion in natural circulation loops in research reactors (RRs). In an effort to recognize the buildup of natural circulation in RRs, pool type upward flow after the pump coasts down due to power loss, by Abdel-Latif et al. [1], was investigated. The setup consists of two vertically stacked pipes that simulate the two branches, one of which contains a test section that is composed of electrically heated, corresponding channels that simulate the core. The second one, represents the portion of the coming back pipe that is involved in the growing of core natural circulation. Several experimental tests under various conditions as the branch’s initial temperature are performed. The channel’s coolant and surface temperatures were monitored. In this study, the thermal-hydraulic (TH) behaviour of the setup is complemented by theoretical analysis using the ANSYS Fluent 17.2 code. The ANSYS Fluent model is validated against the measured values. Typically, the setup is nodlized and a code input is being prepared. The results show that ANSYS Fluent 17.2 qualitatively predicts the thermal hydraulic behaviour and associated flow inversion phenomenon of such facilities. There is a difference between the predicted and measured values, especially for the channel’s surface temperature.

Authors: Richard Mulenga
Published: June 2022

Objectives: To analyze the effect or impact of Digital Services Trade on economic growth (GDP) of a panel of Low, Middle and High Income Countries.

Study Design: Panel Quantitative Study.

Methodology: Dynamic Difference GMM (Diff-GMM) and System GMM (Sys-GMM), Panel pooled OLS (POLS) and Fixed Effects (FE) models were employed in the analyses.

Results: The System GMM estimator seems to predict that, ceteris paribus, a 1 unit increase in digital services exports significantly impacts GDP growth in Low and High Income countries panels in the short run by 5.7% and 52.4% respectively. The panel POLS models estimate that digital services exports cause a significant long run increase in GDP in High income countries by 39.67% relative to 6.68% in the panel of Middle Income countries and negative growth in Low income countries of 7.74%. The FE models predict that for every 1 unit increase in the number of people using the internet, GDP significantly increases by 42.7%, 27.8% and 0.03% in the Middle, High, and Low Income countries panels respectively.

Conclusion: The findings of this study indicate that generally, digital services trade seems to have a significant positive effect on GDP of all country panels. However, Low and Middle Income countries are lagging behind. Therefore, this study recommends that, to promote digital trade driven economic growth, the panel of Low and Middle Income countries’ policy makers should increase investments in both institutional and physical digital infrastructure that enable more people, Small and Medium enterprises(SMEs) and rural populations have access to stable, high speed and affordable digital services.

A Survey work was designed to explore the present status of carp fattening and socio-economic standing of the fish farmers of three upazillas of Dinajpur district such as Dinajpur Sadar, Parbatipur, and Birampur, and was continued until June 2021 from July 2020. Several methodological tools, including participatory rural appraisal (PRA) and primarily a questionnaire survey were used to collect data from 59 fish farmers. The majority of the farmers were between the ages of 41–50, where 45% of them had four to five family members, representing 71.19% nuclear and 28.81% joint families. Large number of the farmers (28.81%) could only sign their names. Approximately 81.35% were Muslims and 18.65% belonged to the Hindus where near about half of the farmers’ (47.46%) annual income were in between BDT 1,00,001-2,0,000. Paka sanitary was utilized by 49.15% respondents. All the farmers drank from tube wells and had access to electricity. The typical pond size was 0.31-40 ha (27.12%), with an average depth of 1.7 m. Farmers owned 59.33% of the ponds, on the other hand, 40.67% were leased ponds and 79.66% had the provision of groundwater for cultivation; however, 50.84% exchanged water whenever required. About 57.63% prepared the ponds and applied 123.5 kg/ha of salt, 12.35-44.5 kg/ha of TSP, and 12.35-75.25 kg/ha of urea. To boost carp growth, 83.08% employed availed growth promoters. Indian major carp and exotic carp were considered for this purpose and have had only fish lice as a constraint throughout the nine to ten months of cultivation period. Commercial feeds were utilized by 40.68% farmers and 81.35% maintained a feeding frequency of two times a day. Majority of them (72.89%) sold live fishes. Lack of scientific knowledge, shortage of high-quality seeds and feeds, lack of funds, and lack of marketing facilities were found to be the main obstructions.
Study on Genetic Variability Estimates of Jackfruit [Artocarpus heterophyllus Lam.] Germplasm at Northern Regions of Tripura State, India
Authors: Debnath Abhijit , Deb Prahlad
Published: June 2022

The experiment was undertaken, during 2019-21, for the purpose of estimation of the genetic variability existing within different quantitative traits among various locally available jackfruit (Artocarpus heterophyllus Lam.) germplasm at northern region of Tripura state. High magnitudes for G.C.V., heritability, genetic advance and genetic advance as percentage of mean were observed for yield, fruit productivity, fruit stalk length and fruit core weight, which might have more role in  improvement of these traits through proficient selection process. Comparatively low genetic advance with high heritability estimates for some of the traits like - seed width, seed length and total sugar content of ripe fruit, could be indicating towards the fact that direct selection based on these characters would be less effective.  Characters such as, number of fruit per cluster, shelf life of fruit and reducing sugar content exhibited wide range of differences between G.C.V. and P.C.V. Hence improvement of these traits by means of selection may not be effective at all.

Bacitracin is a hexapeptide antibiotic, with a substituted thiazolidine nucleus, produced by some strains of B. licheniformis. It is mainly active against Grampositive bacteria, although many differences in susceptibility exist among the bacterial species.Alpharma A.S. Norway has produced bacitracin for use in human medicine since 1954. Until 1998, the fermentation waste from the production of bacitracin was added to animal feed in some European countries, including Norway, to promote growth of pigs and domestic fowl. In 1998, fermentation waste containing bacitracin as a food additive was banned by the EU to reduce the risk of developing bacitracin-resistant bacteria in animals, and the subsequent possible transfer of such bacteria to humans via the food chain. Use of fermentation waste containing bacitracin as a feed additive has not been officially banned in Norway, but it is no longer used for this purpose. Alpharma is therefore actively seeking alternative uses for their production waste. As the waste material is rich in nutrients, the company proposes that it could be developed as a soil additive by fermenting it with chipped bark and lime. The Norwegian Food Safety Authority (Mattilsynet) commissioned the Panel on Biological Hazards of the Norwegian Scientific Committee for Food Safety (Vitenskapskomitéen for mattrygghet) to develop a risk assessment regarding the use of composted waste material from Alpharma’s production of bacitracin, as a soil additive. In response, an ad hoc Working Group of experts was appointed with the mandate to draft a risk assessment which should include the following elements: assessment of risk to human health and/or the environment in relation to residual content of bacitracin in the finished soil additive product and assessment of the risk in relation to dissemination of the production strain and antimicrobial resistance genes.  The Panel on Biological Hazards concludes that the risks to human health and the environment posed by residual bacitracin present in the finished product are minimal. Furthermore, as Bacillus licheniformis is considered essentially non-pathogenic, occurring rarely as an opportunistic pathogen, the risk posed by this bacterium to human health or the environment is very low. It is reasonable to assume that during the early composting process horizontal transfer of bacitracin and erythromycin resistance genes, from the B. licheniformis producer strain to environmental bacteria, will exceed background levels. However, this is considered to represent a low risk to human health and the environment.

Simplex is a new herbicide in Norway containing the active substances aminopyralid and fluroxypyr. Aminopyralid is a new active substance in Norway, but fluroxypyr is found in several authorized products. The application concerns use in established grassland for forage, established ley and pasture and in grass at the first year of sowing. The Norwegian Scientific Committee for Food Safety (VKM) has on a request from the Norwegian Food Safety Authority performed a risk assessment on human health of the active substance and the product. The risk assessment of the product was approved at a meeting May 11 2010 by VKMs Scientific Panel on Pesticides (Panel 2). VKM’s Panel 2 concludes as following: 

Both Simplex and the active substance aminopyralid are characterized as extremely irritating to the eye based on persistent irritation to the eyes of rabbits. The product Simplex is also found irritating to the rabbit skin.  

Aminopyralid has low acute toxicity and is not shown to have genotoxic potential, or to be teratogenic or toxic to the reproduction in animals. There may however be a carcinogenic effect of aminopyralid based on an increased number of uterine sarcomas in mice. The main target organs for sub-chronic and chronic toxicity were the caecum (rats), the stomach (dogs, inflammation) and the liver (dogs, hyperthropy). No adverse effects for chronic toxicity were seen in mice. Rabbit was the most sensitive species for toxicity and the no observed effect levels (NOAELs) derived from studies in this species serve as base for calculations of values for acceptable daily intake (ADI) and acceptable operator exposure level (AOEL).  

The estimated risk for operator is assessed as minimal both by use of boom spraying (46% of AOEL) and knapsack sprayers (81% of AOEL).  

However, as a result of the hazard classification, a faceshield and gloves are necessary personal protective equipment (PPE) to be worn during mixing and loading operations, due to the risk of serious damage to the eyes and skin irritation.

Objective: The current study is to compare the economics of rice cultivation by Conventional method (CR) versus Direct sowing with drum seeder (DSR) and to rank the constraints faced by DSR adopted farmers.

Methods: Cost concepts were used for comparative economic analysis and Garrett ranking technique was used for analysing the constraints faced by the DSR adopted farmers. The present study was conducted in Nalgonda district of Telangana with sample of 80 farmers.

Findings: Direct sowing with drum seeder was proved to be cost effective and profitable compared to conventional rice cultivation. Cost C2 of DSR (81518.9 Rs./ha) was lower than Cost C2 of CR (87535.4 Rs./ha). Net returns of DSR (44839.2 Rs./ha) was higher when compared to CR (41784 Rs./ha).

Conclusion: It is evident from the results of the economic analysis and the feedback received from the farmers that, direct sowing of rice with drum seeder with proper weed management was feasible and most practical alternative for the farmers to go for rice cultivation in the event of uncertain monsoon, increased cost of cultivation and labour shortage besides resource optimization in Telangana state. Therefore, DSR is considered to be the best alternative for rice cultivation addressing the issues of conventional system.

Published: June 2022

Aims: In present time, salinity and alkalinity of the soils are serious problems in India as well as in Gujarat. These soils are usually supposed to be originated as a result of high water table, arid and semi-arid weather, ingress the sea, water, saline nature of barren materials, poor drainage and salt deposition through wind-blown particles. The current study aimed to study the soil chemical properties and organic carbon in soils of Northern Saurashtra coastal region (Jamnagar, Devbhumi Dwarka and Porbandar district) of Gujarat.

Study Design: Field survey and laboratory analysis

Place and Duration of Study: The twenty surface soil samples were collected from each taluka viz. Jodiya, Jamnagar and Lalpur talukas of Jamnagar district, Khambhalia, Dwarka and Kalyanpur talukas of Devbhumi Dwarka district and Porbandar taluka of Porbandar district of Northern Saurashtra Coastal region of Gujarat during May, 2019 and analysed in laboratory of Department of Soil Science & Agricultural Chemistry, JAU, Junagadh (Gujarat) during 2019-2021.

Methodology: In this field-laboratory investigation, 141 grid-based surface (0-15 cm) soil samples were collected from farmer’s field, through the use of GPS at the distance of 0-5, 5-10, 10-15 and 15-20 km from coastal line and analysed for different chemical properties. Sampling sites were selected based on geographical situation, climate and local data of taluka. In laboratory, the collected samples were analysed for SOC, EC2.5, CaCO3, CEC and water-soluble ions.

Results: On the basis of analyzed data, it can be concluded that soil EC2.5 was found beyond to its critical or marginal limit up to 0 to 5 km distance from sea coast. The soil organic carbon status of Northern Saurashtra coastal region was found in medium (5.14 g kg-1) category. The soils are calcareous in nature (CaCO3 121.20 g kg-1) with alkaline in reaction (pH2.5 7.58).

Conclusion: The EC2.5, CaCO3, CEC and water-soluble ions except K+ were decreased, while pH2.5 and SOC were slightly increased with increasing the distance from sea coast. The content of organic carbon in soil was noted below to its critical limit up to 10 km distance from sea coast in Northern Saurashtra which might be due to salinity hazard and shallow light texture.

Objective: There are different anti-inflammatory drugs that are being used in patients with moderate to severe COVID-19 infection. However, in mild to moderate COVID-19 infection, Nimesulide treatment might impede the inflammation with a superior safety profile. Therefore, this study is intended to assess the anti-inflammatory, analgesic and antipyretic activity of Nimesulide in mild to moderate Covid-19 infection.

Methodology: This was an uncontrolled longitudinal study conducted at Pakistan Institute of Medical Sciences Islamabad. The duration of the study was about six months. A total of 66 patients were enrolled. All the patients received Nimesulide 100 mg along with 10 ml sucralfate suspension two times a day for five days. Patients with elevated C-reactive protein or further comorbidities were prescribed 250 mg azithromycin two times a day for five days. Patients with elevated D-dimer (above 500) or other comorbidities were prescribed enoxaparin in a dose of 60 mg subcutaneously once daily for five days. The Primary outcome was estimated in terms of a percent change in oxygen saturation, hospitalization, or death.

Results: The results showed that 31(47.0%) were females and 35(53.0%) were males. The mean oxygen saturation on presentation was 93%±7.9. 24(36.36%) of the patients had D-dimer levels < 250 ng/ml, while 30(45.45%) of the patients had D-dimer levels >250 ng/ml with significant difference between them (p=0.025). 16(24.24%) patients received enoxaparin while 49(74.24%) patients did not received enoxaparin and found a significant difference between the mean change in oxygen saturation of them (p<0.001). 47(71.2%) patients received azithromycin while 19(28.8%) patients did not received azithromycin and found a significant difference between the mean change in oxygen saturation of them (p=0.03).

Conclusion: This study concluded that Nimesulide treatment resulted in a rapid temperature fall within five days. Furthermore, oxygen saturation was also significantly improved in patients treated with Nimesulide.
