Introduction: Depression during perinatal period leads to adverse pregnancy outcome and of child growth. Our study aimed to examine the burden of antenatal depression and associated risk factors among pregnant women living in rural settings of Chennai, a southern state of India.
Background. Polycystic ovarian syndrome (PCOS) is a multifaceted disorder characterized by varying clinical presentations. Objective. The aim of this study was to determine urban and rural differences in the burden of polycystic ovarian syndrome among Indian adolescent females aged 12 to 19 years. Methods. A pilot cross-sectional study was conducted for a period of one month (August-September 2013) at Balaji Hospital, Vellore, Tamil Nadu, India. The final sample included 126 study participants located in various urban (50%, n = 63) and rural (50%, n = 63) settings. Information was gathered on sociodemographic and anthropometric characteristics, clinical history, occurrence of acne and hirsutism, serum testosterone levels, obstetric history, family history of chronic diseases, menstrual history, physical activity, and dietary intake. Results. Eighteen percent of the participants were confirmed of having PCOS by recent guidelines of Rotterdam Consensus for adolescent diagnosis of PCOS (presence of all three elements). Majority of the individuals with PCOS had an average age of 16 (SD = 2) (P = .02) years with an average age of menarche 12 years (SD = 1). Conclusion. The proportion of participants diagnosed with PCOS was higher among urban participants in comparison to rural participants.
Background: Frontline healthcare workers (F-HCWs) are at the forefront of medical care providers against the novel coronavirus 2019 (COVID-19) pandemic which has life-threatening potentials. Inadequate knowledge and incorrect attitudes among HCWs can directly influence practices and lead to delayed diagnosis, poor infection control practices, and spread of disease. Objectives: The aim of this study was to assess the knowledge, attitude and practice (KAP) regarding the COVID-19 pandemic among the frontline healthcare workers (F-HCWs) working at a tertiary care hospital situated in Eastern Uttar Pradesh and to identify the factors significantly associated with KAP. Methods: A cross-sectional study was conducted among 260 health care providers across eastern Uttar Pradesh including Basti city during December 2020. Data was collected using a self-primed pretested questionnaire from the FHCWs working at a tertiary care hospital of eastern Uttar Pradesh. In this survey, a convenience sampling method was adopted. 12 items on knowledge, 10 items on attitude, and 5 items on practices related to COVID-19. The other variables consisted of 4 items on socio-demographic attributes, P-value and 95% confidence intervals (CIs) were performed to assess the attitude and practices in relation to knowledge. Results: Of the total 260 study population, 228 were interviewed online, 32 were self-administered. Knowledge and attitude of the nursing staff were highest but practice score was best for residents. Among different age groups knowledge, attitude and practices scores were highest for 35-45, 45-60 and 25-35 age groups respectively. Respondents having 5-10 years of experience had the best knowledge and the attitude score was highest for HCWs having 10-20 years’ experience but the practice score was higher for HCWs having more than 20 years’ work experience. Overall knowledge score of respondents having strong correlation with attitude (p< 0.05) and to the practice (p<0.05). Conclusion: In this survey many F-HCWs reported adequate overall knowledge with a positive attitude and adopted appropriate practices. The F-HCWs with a higher level of education and more years of experience in health care facilities had better KAP towards COVID-19.
Purpose This study is aims at evaluating the efficacy and sensitivity of specimen pooling for testing of SARS-CoV-2 virus to determine the accuracy, resource savings, and identification of borderline positive cases without impacting the accuracy of the testing. Method This study was conducted between August and October 2020, we performed COVID-19 testing by RT-PCR on the samples from varying prevalence of rural population (non-hot spot) referred to COVID laboratory, in the first step, the samples were collated into pools of 5 or 10. These pools were tested by RT-PCR. Negative pools were reported as negative whereas positive pools of 5 and 10 were then de-convoluted and each sample was tested individually. Results In the present study, we tested 1580 samples in 158 pools of 10 and 17,515 samples in 3503 pools of 5. Among 10 samples pool, 11 (13%) pools flagged positive in the first step. In the second step, among 11 pools (110 samples) de-convoluted strategy was followed in which 10 individual samples came positive. Among 5 samples pool, 164 (13%) pools flagged positive in the first step. In the second step, among 164 pools (820 samples) de-convoluted strategy was followed in which 171 individual samples came positive. The pooled sample testing strategy saves substantial resources and time during surge testing and enhanced pandemic surveillance. This approach requires around 76%–93% fewer tests in low to moderate prevalence settings and group sizes up to 5–10 in a population, compared to individual testing. Conclusion Pooled sample RT- PCR analysis strategies can save substantial resources and time for COVID-19 mass testing in comparison with individual testing without compromising the quality of outcome of the test. In particular, the pooled sample approach can facilitate mass screening in the early asymptomatic stages of COVID-19 infections.
Infection born by Coronavirus SARS-CoV-2 has swept the world within a time of a few months. It has created a devastating effect on humanity with social and economic depressions. Europe and America were the hardest hit continents. India has also lost several lives, making the country fourth most deadly worldwide. However, the infection and death rate per million and the case fatality ratio in India were substantially lower than many of the developed nations. Several factors have been proposed including the genetics. One of the important facts is that a large chunk of Indian population is asymptomatic to the SARS-CoV-2 infection. Thus, the real infection in India is much higher than the reported number of cases. Therefore, the majority of people are already immune in the country. To understand the dynamics of real infection as well as level of immunity against SARS-CoV-2, we have performed antibody testing (serosurveillance) in the urban region of fourteen Indian districts encompassing six states. In our survey, the seroprevalence frequency varied between 0.01-0.48, suggesting high variability of viral transmission among states. We also found out that the cases reported by the Government were several fold lower than the real infection. This discrepancy is majorly driven by a higher number of asymptomatic cases. Overall, we suggest that with the high level of immunity developed against SARS-CoV-2 in the majority of the districts, it is less likely to have a second wave in India.
A number of recent proposals and proposed standards have addressed adding differential services to the Internet. Although their details and tentative implementations d.iffer, most are recommending what essentially amounts to multiple levels of best-effort service. In this paper, we survey recent differential services and pricing proposals and introduce a pricing framework for a differentiated-services network that focuses on simplicity, flexibility, and ease of implementation. In particular, our model can be used in the current heterogeneous Internet without major restructuring. We focus on flat-rate, per-time and usage-based pricing, where users can change their service level on an ad-hoc basis. We also show that a sender-pays model with back-charging is simple to implement and can be effective even in complicated transactions, such as multicasting. Our approach is different from many previous proposals and consciously integrates differential services and pricing with implementation as the immediate goal. Finally, we outline future areas of research including ISP support for pricing, the dynamics of service quality and pricing in a differentiated Internet, and the latest trends and directions of QoS deployment and standardization. RSVP [2]has been proposed by the IETF's integrated services working group as a method for allocating capacity at each router in a flow's path so that, in conjunction with admission control and a bounded-delay queuing discipline, such as Weighted Fair Queuing or one or its variants [3], end-to-end QoS guarantees can be made. However, RSVP is very resource intensive (in terms of signaling and control, as well as requiring per-flow scheduling) and has not enjoyed strong support throughout the networking community. In an effortto extend IP so that it can gracefully support multiple traffic types, each with different QoS requirements, the IETF is currently developing an architecture for providing differentialservices (DS) in the Internet. This architecture defines a number of perhop behaviors (PHBs) that, when indicated in an IP packet header, define how a router should treat the packet. There is no connection setup, management, or teardown. No separate control stream is required and there is no additional overhead for DS, except at the edges of DS networks. The IETF does not explicitly recommend or define end-to-end servicesinstead it hopes to provide a rich enough set of PHBs so that arbitrary end-to-end services can be built on top of these primitives. The PHBs do not specify or recommend packet-scheduling or queuemanagement disciplines. Thus, it is up to the market (ISPs and router manufac-turers) to create and sell differential services to the Internet community. It is possible that some providers will feature multiple levels of best-effort
Diabetes is a growing public health concern in Indian subcontinent. More and more people are searching internet for health information, however, the quality of internet-based medical information is extremely variable. This study aims to evaluate quality of health information about type-II diabetes mellitus in an Indian context. We used key words 'diabetes', 'diabetes management', 'diabetes prevention' and 'diabetes monitoring' and searched over Google, Yahoo and Bing during August 2011. Two independent reviewers used DISCERN tool to assess quality of health information of the final 84 websites. Majority of the websites were '.com' and DISCERN scores were highest in 'other' category. Inter-rater reliability analysis suggests 81% (N = 17) DISCERN criteria are in substantial agreement between two reviewers. There is no significant difference between two reviewers as well as among four website categories (.com, .edu, .org and others) for reliability of publication, specific details about treatment choices and overall quality rating.
Background and Purpose: Superficial mycosis is more prevalent in tropical and subtropical countries, such as India. Regarding this, the present study was conducted to determine the epidemiology of superficial mycosis and identify the most common dermatophytic species in this region. Materials and Methods: For the purpose of the study, a total of 220 skin scraping, nail, and hair root specimens were collected. Direct microscopic examination was performed using potassium hydroxide mount. Additionally, the samples were inoculated onto Sabouraud dextrose agar (SDA) and dermatophyte test medium (DTM). The fungal colony of each isolates was stained with lactophenol cotton blue mount, and observed under microscope for species identification. Results: Out of 220 isolates, 172 samples, obtained from 108 males 64 females, were positive for skin fungal infections by either KOH mount or culture. Furthermore, 113 isolates were identified as dermatophytes, while 59 samples were found to be non-dermatophytes. Among the dermatophytes isolated from different clinical samples, Trichophyton verrucosum (42/113, 38%) was the most common species, and Tinea corporis was the most common infection (36.2%). Conclusion: As the findings indicated, dermatophytes had an isolation rate of 78%, which is higher than normal. This can be due to the fact that the majority of the patients were from a rural background (71.7%) with a low socioeconomic status and poor personal hygiene who were exposed to climatic changes.
