COVID-19 has been declared as a global pandemic by the World Health Organization (WHO) since its outbreak in December 2019. In India, as of May 12th 2021, the total number of coronavirus cases and associated deaths are 2,35,57,676 and 2,56,617 respectively. To control the spread of the virus effectively, social distancing, self-isolation and quarantine, lockdowns and mass inoculation are vital. In this paper we propose a deterministic epidemic model which is an extension of the SEIR model to understand the disease dynamics.The proposed model has eight compartments, Susceptible1, Susceptible2, Exposed, Infected, Quarantined, Isolated, Recovered and Dead and is termed as the S1S2EIQJRD model. The basic reproduction number Ris derived for the proposed model and it is shown that for the disease dies out and for the disease is endemic. Numerical simulations for the growth of the virus across India through the span of the outbreak are obtained. The simulation is done on real data and the results obtained may be used to make suitable inferences about the dynamics of the disease and appropriate measures can be taken to control its spread.
自2019年12月新冠肺炎疫情爆发以来,世界卫生组织(世卫组织)已宣布其为全球大流行。在印度,截至2021年5月12日,冠状病毒病例总数和相关死亡人数分别为2,35,57,676和2,56,617。为有效控制疫情传播,保持社会距离、自我隔离检疫、居家隔离和大规模接种至关重要。在本文中,我们提出了一个确定性流行病模型,它是SEIR模型的扩展,以理解疾病动力学。提出的模型有8个隔间,分别是易感区1、易感区2、暴露区、感染区、隔离区、隔离区、恢复区和死亡区,被称为S1S2EIQJRD模型。为所提出的模型导出了基本繁殖数,并表明该疾病会灭绝,并且该疾病是地方性的。在整个暴发期间,获得了病毒在印度各地生长的数值模拟。对实际数据进行了模拟,所得结果可用于对疾病的动态进行适当的推断,并可采取适当的措施来控制其传播。

Background: Diabetes is a major public health challenge in the present phase of socio-demographic and epidemiological transition leading to various complications causing high mortality and morbidity. Diabetes is often not diagnosed in early phase especially in rural areas. This study was carried out to observe changing trends, prevalence of diabetes and its association with major risk factors in rural community. Methods: A community based cross sectional study was carried out among 700 individuals (306 men and 394 women) aged 18-65 years living in villages under rural field practice area of Dr. Pinnamaneni Siddhartha Institute of Medical Sciences and Research Foundation, Chinaoutpally, Krishna district, Andhra Pradesh. Information on socio-demographic data, dietary habits and life style was obtained. Height, weight,blood pressure and capillary blood glucose were measured. Conclusion: The prevalence of diabetes is about 22.6% of the study subjects of whom 11.9% are known and 10.7% are newly diagnosed. The prevalence of Diabetes is increasing at an alarming rate even in rural population and nearly half of them aren’t aware of their diabetes status. Diabetes when detected early can prevent lot of complications and improve the quality of life of the individual.

Background: generalized anxiety disorder is a mental health disorder manifested by a lot of worry with no real cause and more intense than situation need. Few publications on anxiety among preschool anxiety in Iraq. Objective: to report on generalized anxiety disorder among preschool children in Iraq (prevalence and determinant factors). Methods: A total 423 preschool children was included in the study. They were recruited from 4 public and 4 private kindergartens. They were selected randomly from Al-Rusafa Al-Thania Education directorate (one out 3 directorates in Al-Rusafa). Spence Child Anxiety Scale-parent version was used to assess the anxiety. Results: Generalized anxiety disorder was observed in 37.4% of children. Among the ages 4, 5, and 6 years, generalized anxiety disorder was observed in 37.2%, 35% and 4.3%, respectively. Rate of the disorder among males was 34.2% and among females was 40.2%. In public kindergartens the rate of the disorder was significantly higher (43%)than in private ones (31.6%). In low, middle and high socioeconomic status the rate of disorder were 57.7%, 29.2% and 34.4%, respectively. Paternal and maternal educational levels were significantly affecting the rate of generalized anxiety disorder (p = 0.003 and 0.009, respectively). The rate of the disorder among preschool children cared by one parent was significantly higher (86.6%) than those cared by both parents (27.4%) (p=0.0001). Conclusion: A high prevalence of generalized anxiety disorder among preschool children was observed. Private kindergarten showed lower rate of the disorder than the public ones.
背景:广泛性焦虑障碍是一种心理健康障碍,表现为大量的无真实原因的担忧,比情况需要更强烈。关于伊拉克学龄前儿童焦虑的出版物很少。目的:报道伊拉克学龄前儿童广泛性焦虑障碍(患病率及决定因素)。方法:对423名学龄前儿童进行调查。他们分别来自4所公立幼儿园和4所私立幼儿园。他们是从Al-Rusafa Al-Thania教育理事会(Al-Rusafa 3个理事会中的一个)中随机选出的。采用斯宾塞儿童焦虑量表-家长版进行焦虑评估。结果:37.4%的患儿存在广泛性焦虑障碍。在4岁、5岁和6岁儿童中,广泛性焦虑障碍的发生率分别为37.2%、35%和4.3%。男性患病率为34.2%,女性患病率为40.2%。公办幼儿园的患病率(43%)明显高于私立幼儿园(31.6%)。低、中、高社会经济地位人群的精神障碍发生率分别为57.7%、29.2%和34.4%。父亲和母亲的受教育程度显著影响广泛性焦虑障碍的发生率(p分别= 0.003和0.009)。单亲照料的学龄前儿童的障碍发生率(86.6%)显著高于双亲照料的学龄前儿童(27.4%)(p=0.0001)。结论:广泛性焦虑障碍在学龄前儿童中有较高的患病率。民办幼儿园儿童的儿童心理障碍发生率低于公办幼儿园。

Background: Bangladesh is trying to shape out coronavirus disease of 2019 (COVID-19) pandemic with limited frontiers resources science March 2020. Among all frontier, Bangladeshi nurses are also playing a dynamic role to control infection through direct contact with COVID patients. Objective: This research aims to identify the level and predictors of poor knowledge of nursing students toward the COVID-19. Method: This study was a quantitative type of cross-sectional study with 150 participants randomly selected from 226 students of the Armed Forces Medical Institute located in Dhaka Cantonment of Dhaka city of Bangladesh. Data were collected by using a pre-tested questionnaire through a telephonic interview by trained and experienced interviewers. Analysis was done by using univariate, multivariate techniques followed by regression modeling. Result: Overall level of knowledge was observed poor (67.3%) among more than half of BSc nursing students. A greater part of nursing students got poor knowledge on the preventive measures to reduce transmission of COVID 19 (98.7%;40.20±12.39) & management of COVID 19 (94.7%;40.20±12.39). In terms of predicting the causes of poor knowledge, this study found that BSc nursing students of the second year (AOR= 2.53, p < 0.01) are more likely to have poor knowledge on COVID-19 compared to another educational group. Conclusion: Nurses are the frontiers to mitigate COVID-19 and manage the affected people effectively. Therefore, knowledge of them needs to be perfect to ensure the proper practice to prevent COVID-19. Thus, an enthusiastic and demonstrative learning system is required to make them knowledgeable enough against COVID-19.
背景:孟加拉国正试图在有限的前沿资源下应对2019年冠状病毒病(COVID-19)大流行。在所有边境地区,孟加拉国护士也在通过与COVID - 19患者直接接触来控制感染方面发挥着积极作用。目的:了解护生对新型冠状病毒肺炎的认知水平及其影响因素。方法:本研究采用定量横断面研究,随机从孟加拉国达卡市达卡军营武装部队医学研究所226名学生中抽取150名参与者。数据由经过培训和经验丰富的采访者通过电话采访使用预先测试的问卷收集。分析采用单变量、多变量技术,然后进行回归建模。结果:半数以上护生整体知识水平较差(67.3%)。大部分护生对减少COVID - 19传播的预防措施(98.7%;40.20±12.39)和COVID - 19管理(94.7%;40.20±12.39)的知识贫乏。在对知识贫乏原因的预测方面,本研究发现本科护生二年级对新冠肺炎知识贫乏的发生率高于其他学历组(AOR= 2.53, p < 0.01)。结论:护士是防控新冠肺炎疫情、有效管理患者的前沿阵地。因此,需要充分了解这些知识,以确保正确预防COVID-19。因此,需要一个充满热情和示范性的学习系统,以使他们对COVID-19有足够的了解。

Aims: The aim of this study is to determine, compare the Cg-A levels in saliva and plasma in periodontal healthy, in patients with periodontal disease and correlate the same with the stress factor. Materials and Methods: The study involved thirty subjects. There were categorized into three groups with Group I (10 subjects with healthy periodontal status), Group II (10 subjects with mild to moderate periodontitis) and Group III (10 subjects with severe periodontitis). The clinical parameters such as plaque index, gingival bleeding index, clinical attachment loss and probing depth were recorded. Stress was measured using Holme and Rahe stress rating scale. Blood and Saliva sample were collected and Serum Plasma and Saliva CgA levels evaluated using ELISA. The data obtained from all the three groups were analyzed using SPSS Systat 12 software. The mean variables between the three groups were analysed using Kruskal Wallis test. The correlation between the variables and the stress scores was assessed by Pearson’s correlation test. Results: The results of the study showed significantly higher CgA levels in saliva and plasma of patients with severe periodontitis compared with moderate periodontitis and healthy individuals (P < 0.05). There was also a positive correlation between stress scores and Salivary, Serum CgA levels and all clinical parameters. Conclusion: A significant association between elevated Cg A levels in saliva and plasma with periodontal disease was present in our study. The results suggest that Salivary and Plasma Cg A can be considered as a useful biomarker for evaluating etiopathogenesis of Periodontitis.
目的:本研究的目的是测定、比较牙周健康者和牙周病患者唾液和血浆中Cg-A的水平,并将其与应激因素联系起来。材料与方法:本研究共涉及30例受试者。将患者分为三组:ⅰ组(10例牙周健康)、ⅱ组(10例轻中度牙周炎)和ⅲ组(10例重度牙周炎)。记录牙菌斑指数、牙龈出血指数、临床附着丧失、探诊深度等临床参数。应力测量采用Holme和Rahe应力评定量表。采集血样和唾液,采用ELISA法测定血清、血浆和唾液CgA水平。采用SPSS Systat 12软件对三组数据进行分析。采用Kruskal - Wallis检验分析三组间的平均变量。采用Pearson相关检验评估各变量与压力得分之间的相关性。结果:研究结果显示,重度牙周炎患者唾液和血浆中CgA水平明显高于中度牙周炎和健康人群(P < 0.05)。应激评分与唾液、血清CgA水平及各项临床指标均呈正相关。结论:在我们的研究中,唾液和血浆中Cg A水平升高与牙周病存在显著关联。结果表明,唾液和血浆Cg A可作为评估牙周炎发病机制的有用生物标志物。

Introduction: Contact tracing commenced in districts of Western Rajasthan in March 2020 to control the spread of Covid-19.It was an ongoing process involving isolation and sampling of contacts. Multi department Quick and Rapid response teams (Q/RRT) worked continuously as the pandemic passed through different stages. The objectives of the study was to compare the challenges faced during contact tracing and document good practices in place. Methods: A cross –sectional study was done among contact tracers using a semi structured questionnaire in Google forms in three districts of Pali, Jodhpur and Barmer. Keeping power of study at 80%, 5% error and 95% confidence interval, assuming 50% prevalence of effective contact tracing and 10 % non-response total 400, i.e 133 participants from each district. Results: Major challenges faced by tracers were resistance to contact sampling (64%)lack of training (49%), and random sampling workload (47%). Overall 36% of contacts had downloaded the Aarogya setu app but among them only 68% were using the app. Trainings, workload distribution and inter-sectoral coordination was best in Jodhpur, Barmer and Pali respectively. Conclusions: Trainings helped in better field management of resistance to sampling among contacts. Excessive workload of lab technicians lead to errors in reporting. Transport for sampling of contacts was a challenge in remote areas. The Aarogya setu app was not used by all contacts. Regular feedback meetings by local administration helped in effective contact tracing.
导语:为控制Covid-19的传播,拉贾斯坦邦西部地区于2020年3月开始追踪接触者。这是一个持续的过程,涉及对接触者进行隔离和抽样。随着大流行经历不同阶段,多部门快速反应小组(Q/RRT)不断开展工作。该研究的目的是比较接触者追踪过程中面临的挑战,并记录现有的良好做法。方法:在巴利、焦特布尔和巴默三个地区使用半结构化问卷对接触者进行横断面研究。假设有效接触者追踪率为50%,无应答率为10%,总共400人,即来自每个地区的133名参与者,将研究效力保持在80%,5%误差和95%置信区间。结果:示踪人员面临的主要挑战是对接触抽样的抗拒(64%)、缺乏培训(49%)和随机抽样工作量(47%)。总体而言,36%的联系人下载了Aarogya setu应用程序,但其中只有68%的人在使用该应用程序。培训、工作量分配和部门间协调在焦特布尔、巴默和巴利语分别是最好的。结论:培训有助于更好地管理接触者的抽样抗性。实验室技术人员的过度工作量导致报告错误。在偏远地区,运送接触者取样是一项挑战。并不是所有联系人都使用了Aarogya setu应用。地方行政部门定期召开反馈会议有助于有效追踪接触者。

Multi department Quick and Rapid response teams (Q/RRT) worked continuously as the pandemic passed through different stages. The objectives of the study was to compare the challenges faced during contact tracing and document good practices in place. Methods: A cross –sectional study was done among contact tracers using a semi structured questionnaire in Google forms in three districts of Pali, Jodhpur and Barmer. Keeping power of study at 80%, 5% error and 95% confidence interval, assuming 50% prevalence of effective contact tracing and 10 % non-response total 400, i.e 133 participants from each district. Results: Major challenges faced by tracers were resistance to contact sampling (64%)lack of training (49%), and random sampling workload (47%). Overall 36% of contacts had downloaded the Aarogya setu app but among them only 68% were using the app. Trainings, workload distribution and inter-sectoral coordination was best in Jodhpur, Barmer and Pali respectively. Conclusions: Trainings helped in better field management of resistance to sampling among contacts. Excessive workload of lab technicians lead to errors in reporting. Transport for sampling of contacts was a challenge in remote areas. The Aarogya setu app was not used by all contacts. Regular feedback meetings by local administration helped in effective contact tracing.","PeriodicalId":13368,"journal":{"name":"Indian Journal of Public Health Research and Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78557267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Delivery of healthcare services needs to be rooted in frameworks supporting community engagement. Our organization delivers primary eyecare through two different models. These case studies quantitatively analyse the impact of community collaboration on the effectiveness of these models-camps and vision centres. Methods: Camp data from two rural blocks of north India comparing first year of operations in 2016 with that of 2017; April-September 2017 data from two underperforming vision centreswas compared to data from same period in 2018.Natural interventions in camps included visits of local leaders to surgical centre, health talks spreading awareness regarding eyecare plusour organization, and local partners helping counsel patients, while for vision centres,staff was trained to conduct regular health talks and meetings in nearby villages. For camps, before and after data on attendance, proportion of people over 50, proportion of people getting operated among those advised and acquisition cost were analysed,for vision centres referral from these centres wereanalysed. Results: Parameters for both models showed improvement inthe second year. Conclusion: Sustained presence in the community and collaboration with local stakeholders increases effectiveness of service delivery at primary level.
背景:卫生保健服务的提供需要植根于支持社区参与的框架。我们的组织通过两种不同的模式提供初级眼科保健。这些案例研究定量分析了社区合作对这些模式——营地和愿景中心——有效性的影响。方法:来自印度北部两个农村地区的营地数据,比较2016年和2017年第一年的运营情况;将两个表现不佳的视觉中心2017年4月至9月的数据与2018年同期的数据进行了比较。营地的自然干预措施包括当地领导人访问外科中心,举行保健讲座,传播关于眼科保健和组织的认识,以及当地合作伙伴帮助为病人提供咨询,而对于视力中心,培训工作人员定期在附近村庄举行保健讲座和会议。对于营地,分析了出席的前后数据,50岁以上的人的比例,被建议的人中接受手术的人的比例和获得成本,对于视力中心,分析了这些中心的转诊。结果:两种模型的参数在第二年均有改善。结论:在社区的持续存在和与当地利益相关者的合作提高了初级服务提供的有效性。

Objective: To study the prevalence of thyroid disorders and its correlation with menstrual disorders. Methods: 100 women aged between 15 and 45 years who attended gyne OPD in Sraswathi medical college, U.P, were included for this cross-sectional study. The study group comprised 50 patients presented with menstrual complaints. The control group consisted of 50 women of same age group with complaints other than menstrual disorders. Thyroid function tests, anti-TPO antibody estimation, and endometrial sampling were done in all patients. Results: In patients with menstrual disorders, 44 % had thyroid disorders in which subclinical hypothyroidism was prevalent in 20 %, overt hypothyroidism in 14 %, and overt hyperthyroidism in 8 % of the women. Autoimmune thyroid antibodies were present in 30 % patients of women with menstrual disorders. On endometrial sampling, hypothyroid patients mainly had proliferative endometrium (42.85 %) whereas hyperthyroid had atrophic endometrium (60 %). Conclusions: Thyroid dysfunction is an important causative etiology of menstrual abnormalities. Assessment of thyroid function should be done in all patients with menstrual disorders to avoid unnecessary interventions like curettage and hysterectomy.
目的:了解甲状腺疾病的患病率及其与月经紊乱的关系。方法:100名年龄在15 - 45岁的妇女,她们在Sraswathi医学院妇科门诊就诊,upp,纳入本横断面研究。研究小组包括50名出现月经不适的患者。对照组为50例同年龄段除月经紊乱外有其他症状的女性。所有患者均进行甲状腺功能检查、抗tpo抗体检测和子宫内膜取样。结果:在月经紊乱的患者中,44%患有甲状腺疾病,其中亚临床甲状腺功能减退占20%,明显甲状腺功能减退占14%,明显甲状腺功能亢进占8%。自身免疫性甲状腺抗体存在于30%的女性月经紊乱患者中。子宫内膜取样显示,甲状腺功能减退患者以增生性子宫内膜为主(42.85%),甲状腺功能亢进患者以萎缩性子宫内膜为主(60%)。结论:甲状腺功能障碍是月经异常的重要病因。所有月经紊乱的患者都应进行甲状腺功能评估,以避免不必要的干预,如刮宫和子宫切除术。
