These guidelines have been written to provide a straightforward approach to managing hypertension in the community. We have intended that this brief curriculum and set of recommendations be useful not only for primary care physicians and medical students, but for all professionals who work as hands-on practitioners. We are aware that there is great variability in access to medical care among communities. Even in so-called wealthy countries there are sizable communities in which economic, logistic, and geographic issues put constraints on medical care. And, at the same time, we are been reminded that even in countries with highly limited resources, medical leaders have assigned the highest priority to supporting their colleagues in confronting the growing toll of devastating strokes, cardiovascular events, and kidney failure caused by hypertension. Our goal has been to give sufficient information to enable health care practitioners, wherever they are located, to provide professional care for people with hypertension. All the same, we recognize that it will often not be possible to carry out all of our suggestions for clinical evaluation, tests, and therapies. Indeed, there are situations where the most simple and empirical care for hypertension—simply distributing whatever antihypertensive drugs might be available to people with high blood pressure—is better than doing nothing at all. We hope that we have allowed sufficient flexibility in this statement to enable responsible clinicians to devise workable plans for providing the best possible care for patients with hypertension in their communities. Note: This preferably should be a fasting sample so that a fasting blood glucose level and more accurate lipid profiles can be obtained. Several lifestyle interventions have been shown to reduce blood pressure. Apart from contributing to the treatment of hypertension, these strategies are beneficial in managing most of the other cardiovascular risk factors. In patients with hypertension that is no more severe than stage 1 and is not associated with evidence of abnormal cardiovascular findings or other cardiovascular risks, 6 to 12 months of lifestyle changes can be attempted in the hope that they may be sufficiently effective to make it unnecessary to use medicines. However, it may be prudent to start treatment with drugs sooner if it is clear that the blood pressure is not responding to the lifestyle methods or if other risk factors appear. Also, in practice settings where patients have logistical difficulties in making regular clinic visits, it might be most practical to start drug therapy early. In general, lifestyle changes should be regarded as a complement to drug therapy rather than an alternative. Starting treatment: (see the algorithm in the Figure). Treatment with drugs should be started in patients with blood pressures >140/90 mm Hg in whom lifestyle treatments have not been effective. (Note: As discussed earlier in Section 12 on Nonpharmacologic Treatment, drug treatment can be delayed for some months in patients with stage 1 hypertension who do not have evidence of abnormal cardiovascular findings or other risk factors. In settings where healthcare resources are highly limited, clinicians can consider extending the nondrug observation period in uncomplicated stage 1 hypertensive patients provided there is no evidence for an increase in blood pressure or the appearance of cardiovascular or renal findings). In patients with stage 2 hypertension (blood pressure ≥160/100 mm Hg), drug treatment should be started immediately after diagnosis, usually with a 2-drug combination, without waiting to see the effects of lifestyle changes. Drug treatment can also be started immediately in all hypertensive patients in whom, for logistical or other practical reasons, the practitioner believes it is necessary to achieve more rapid control of blood pressure. The presence of other cardiovascular risk factors should also accelerate the start of hypertension treatment. Note: There is an assumption, unless otherwise stated, that all drugs in a class are similar to each other. We only mention individual agents if they have an important property that is not shared by the others in its class. Table 2 provides a list of commonly used antihypertensive drugs and their doses. Note: Thiazides plus β-blockers are also an effective combination for reducing blood pressure, but since both classes can increase blood glucose concentrations this combination should be used with caution in patients at risk for developing diabetes. The authors of this statement acknowledge that there are insufficient published data from clinical trials in hypertension to create recommendations that are completely evidence-based, and so inevitably some of our recommendations reflect expert opinion and experience. We also should point out that because of the major differences in resources among points of care it is not possible to create a uniform set of guidelines. For this reason we have written a broad statement on the management of hypertension and have not presumed to anticipate the conditions or shortfalls that might exist in particular communities. We expect that experts who are familiar with local circumstances will feel free to use their own judgment in modifying our recommendations and to create practical instructions to help guide front-line practitioners in providing the best care possible. The authors of this statement would welcome comments and suggestions from colleagues. We recognize that in this initial version of the guidelines there will probably be omissions, redundancies, and inaccuracies. Please feel free to get in touch with us either by letters to the Journal or by personal communication.

OBJECTIVES: Women with a sonographic short cervix in the mid-trimester are at increased risk for preterm delivery. This study was undertaken to determine the efficacy and safety of using micronized vaginal progesterone gel to reduce the risk of preterm birth and associated neonatal complications in women with a sonographic short cervix. METHODS: This was a multicenter, randomized, double-blind, placebo-controlled trial that enrolled asymptomatic women with a singleton pregnancy and a sonographic short cervix (10-20 mm) at 19 + 0 to 23 + 6 weeks of gestation. Women were allocated randomly to receive vaginal progesterone gel or placebo daily starting from 20 to 23 + 6 weeks until 36 + 6 weeks, rupture of membranes or delivery, whichever occurred first. Randomization sequence was stratified by center and history of a previous preterm birth. The primary endpoint was preterm birth before 33 weeks of gestation. Analysis was by intention to treat. RESULTS: Of 465 women randomized, seven were lost to follow-up and 458 (vaginal progesterone gel, n=235; placebo, n=223) were included in the analysis. Women allocated to receive vaginal progesterone had a lower rate of preterm birth before 33 weeks than did those allocated to placebo (8.9% (n=21) vs 16.1% (n=36); relative risk (RR), 0.55; 95% CI, 0.33-0.92; P=0.02). The effect remained significant after adjustment for covariables (adjusted RR, 0.52; 95% CI, 0.31-0.91; P=0.02). Vaginal progesterone was also associated with a significant reduction in the rate of preterm birth before 28 weeks (5.1% vs 10.3%; RR, 0.50; 95% CI, 0.25-0.97; P=0.04) and 35 weeks (14.5% vs 23.3%; RR, 0.62; 95% CI, 0.42-0.92; P=0.02), respiratory distress syndrome (3.0% vs 7.6%; RR, 0.39; 95% CI, 0.17-0.92; P=0.03), any neonatal morbidity or mortality event (7.7% vs 13.5%; RR, 0.57; 95% CI, 0.33-0.99; P=0.04) and birth weight < 1500 g (6.4% (15/234) vs 13.6% (30/220); RR, 0.47; 95% CI, 0.26-0.85; P=0.01). There were no differences in the incidence of treatment-related adverse events between the groups. CONCLUSIONS: The administration of vaginal progesterone gel to women with a sonographic short cervix in the mid-trimester is associated with a 45% reduction in the rate of preterm birth before 33 weeks of gestation and with improved neonatal outcome.

OBJECTIVE: Preterm birth is the leading cause of perinatal morbidity and mortality worldwide. Treatment of preterm labor with tocolysis has not been successful in improving infant outcome. The administration of progesterone and related compounds has been proposed as a strategy to prevent preterm birth. The objective of this trial was to determine whether prophylactic administration of vaginal progesterone reduces the risk of preterm birth in women with a history of spontaneous preterm birth. METHODS: This randomized, double-blind, placebo- controlled, multinational trial enrolled and randomized 659 pregnant women with a history of spontaneous preterm birth. Between 18 + 0 and 22 + 6 weeks of gestation, patients were assigned randomly to once-daily treatment with either progesterone vaginal gel or placebo until either delivery, 37 weeks' gestation or development of preterm rupture of membranes. The primary outcome was preterm birth at </= 32 weeks of gestation. The trial was analyzed using an intent-to-treat strategy. RESULTS: Baseline characteristics were similar in the two treatment groups. Progesterone did not decrease the frequency of preterm birth at </= 32 weeks. There was no difference between the groups with respect to the mean gestational age at delivery, infant morbidity or mortality or other maternal or neonatal outcome measures. Adverse events during the course of treatment were similar for the two groups. CONCLUSION: Prophylactic treatment with vaginal progesterone did not reduce the frequency of recurrent preterm birth (</= 32 weeks) in women with a history of spontaneous preterm birth. The effect of progesterone administration in patients at high risk for preterm delivery as determined by methods other than history alone (e.g. sonographic cervical length) requires further investigation.

OBJECTIVE: To investigate the efficacy of vaginal progesterone to prevent early preterm birth in women with sonographic evidence of a short cervical length in the midtrimester. METHODS: This was a planned, but modified, secondary analysis of our multinational, multicenter, randomized, placebo-controlled trial, in which women were randomized between 18 + 0 and 22 + 6 weeks of gestation to receive daily treatment with 90 mg of vaginal progesterone gel or placebo. Cervical length was measured with transvaginal ultrasound at enrollment and at 28 weeks of gestation. Treatment continued until either delivery, 37 weeks of gestation or development of preterm rupture of membranes. Maternal and neonatal outcomes were evaluated for the subset of all randomized women with cervical length < 28 mm at enrollment. The primary outcome was preterm birth at </= 32 weeks. RESULTS: A cervical length < 28 mm was identified in 46 randomized women: 19 of 313 who received progesterone and 27 of 307 who received the placebo. Baseline characteristics of the two groups were similar. In women with a cervical length < 28 mm, the rate of preterm birth at </= 32 weeks was significantly lower for those receiving progesterone than it was for those receiving the placebo (0% vs. 29.6%, P = 0.014). With progesterone, there were fewer admissions into the neonatal intensive care unit (NICU; 15.8% vs. 51.9%, P = 0.016) and shorter NICU stays (1.1 vs. 16.5 days, P = 0.013). There was also a trend toward a decreased rate of neonatal respiratory distress syndrome (5.3% vs. 29.6%, P = 0.060). CONCLUSION: Vaginal progesterone may reduce the rate of early preterm birth and improve neonatal outcome in women with a short sonographic cervical length.

AIM: The aim of this analysis of renal biopsies in people with type 2 diabetes was to know the prevalence and nature of non-diabetic renal disease (NDRD) and to note its correlation with the duration of diabetes, extent of proteinuria and presence or absence of retinopathy. METHODS: From January 2000 to December 2004, 160 people with type 2 diabetes with clinically suspected NDRD underwent renal biopsy reported by a single pathologist. The case records of these patients were retrospectively analysed. Based on the biopsy findings, patients were grouped as Group I, isolated NDRD; Group II, NDRD with underlying diabetic glomerulosclerosis; and Group III, isolated diabetic glomerulosclerosis. The relation of histology with clinical profile in each group was noted and statistically analysed using strata 6 software. RESULTS: Of the 160 patients studied, 118 were males and 42 were females (2.8:1). The average age was 51.35 years (30-79). Indications for renal biopsy included: nephrotic syndrome in 55 (34.37%), acute renal failure (ARF) in 49 (30.62%), rapidly progressive renal failure (RPRF) in 24 (15%), absent retinopathy in 19 (11.87%), haematuria in 10 (6.25%) and acute on chronic renal failure (CRF) in three (1.87%) patients. Group I included 68 patients (42.50%), Group II included 48 patients (30%) and Group III included 44 patients (27.50%). The mean duration of diabetes was 5.37, 10.12 and 6.86 years in Groups I, II and III respectively. The duration of diabetes was significantly less in Group I compared with Group II and III combined (5.37 vs 8.53; P < 0.001). Diabetic retinopathy was absent in 61 (38.13%) patients, of whom 41 (67.21%) had isolated NDRD. The most common NDRD were acute interstitial nephritis (18.1%), post infectious glomerulonephritis (17.24%), membranous nephropathy (11.20%) and focal segmental glomerulosclerosis (7.75%). CONCLUSIONS: Prevalence of NDRD (either isolated or superimposed on underlying diabetic glomerulosclerosis) is very high in appropriate clinical settings. The shorter duration of diabetes and the absence of retinopathy, especially when associated with nephrotic proteinuria, strongly predict NDRD.

BACKGROUND: While many studies have compared the efficacy of Pap cytology, visual inspection with acetic acid (VIA) and human papillomavirus (HPV) DNA assays for the detection cervical intraepithelial neoplasia and cancer, few have evaluated the program effectiveness. METHODS AND FINDINGS: A population-based sample of 5603 women from Medchal Mandal in Andhra Pradesh, India were invited to participate in a study comparing Pap cytology, VIA, and HPV DNA screening for the detection of CIN3+. Participation in primary screening and all subsequent follow-up visits was rigorously tracked. A 20% random sample of all women screened, in addition to all women with a positive screening test result underwent colposcopy with directed biopsy for final diagnosis. Sensitivity, specificity, positive and negative predictive values were adjusted for verification bias. HPV testing had a higher sensitivity (100%) and specificity (90.6%) compared to Pap cytology (sensitivity = 78.2%; specificity = 86.0%) and VIA (sensitivity = 31.6%; specificity = 87.5%). Since 58% of the sample refused involvement and another 28% refused colposcopy or biopsy, we estimated that potentially 87.6% of the total underlying cases of CIN3 and cancer may have been missed due to program failures. CONCLUSIONS: We conclude that despite our use of available resources, infrastructure, and guidelines for cervical cancer screening implementation in resource limited areas, community participation and non-compliance remain the major obstacles to successful reduction in cervical cancer mortality in this Indian population. HPV DNA testing was both more sensitive and specific than Pap cytology and VIA. The use of a less invasive and more user-friendly primary screening strategy (such as self-collected swabs for HPV DNA testing) may be required to achieve the coverage necessary for effective reduction in cervical cancer mortality.

BACKGROUND: Thyroid hormones influences glucose homeostasis. The association of insulin resistance in overt hypothyroidism is well proven, but very less information is available about insulin action on subclinical hypothyroidism. OBJECTIVE: This study was done to evaluate the association between thyroid hormones and insulin resistance in subclinical hypothyroidism (SCH). MATERIALS AND METHODS: Thirty subjects diagnosed as SCH and 30 age matched euthyroids were included. Serum TSH, FT3, FT4, fasting plasma glucose and insulin were estimated. Homeostasis Model Assessment was used to assess insulin resistance (HOMA- IR). RESULTS AND CONCLUSION: Serum TSH levels were significantly increased in SCH (14.20 ± 5.23 μU/ml) when compared with euthyroids (2.24 ±1.43μU/ml; P< 0.0001). Serum FT3, FT4 levels in SCH (2.96±0.80 pg/ml & 1.15 ± 0.52 ng/dl) were within the normal range. The mean insulin levels were significantly elevated in SCH (9.07±3.41 μU/ml) when compared with euthyroids (5.28± 2.18 μU/ml; P-value < 0.0001). The mean HOMA IR was significantly elevated in SCH (2.03 ± 0.95) when compared with euthyroids (1.05±0.45, P-value < 0.0001). TSH levels positively and moderately correlated with insulin (r= 0.43 P=0.03) and HOMA IR (r =0.48; P= 0.01). FT3 levels negatively and strongly correlated with insulin (r= -0.5, P=0.004) and moderately with HOMA IR (r= -0.38, P= 0.04). FT4 levels negatively and weakly correlated with insulin and IR (r= - 0.11, P=0.54; r= - 0.07, P=0.69 respectively). To conclude, SCH is associated with insulin resistance. Hence there is an increased risk of insulin resistance associated disorders such as metabolic syndrome, cardiovascular events in SCH.

OBJECTIVES: Our aim was to determine if (1) Hybrid Capture 2 and a PCR-based method were comparable for detection of high-risk human papillomavirus (HPV) clinician-collected and self-collected samples were equally efficient to detect HPV and cervical cancer precursor lesions, and (3) if participation rates improved with home-based versus clinic-based self collection. METHODS: Samples were selected from women participating in a cervical cancer screening study according to HPV, visual inspection with acetic acid, or Pap smear screening results. From 432 of 892 selected women, split sample aliquots were tested for HPV DNA using both the Hybrid Capture 2 assay and the Roche prototype line blot assay. Women from a subset of villages were recruited at two separate time points for clinic-based self-collection and home-based self-collection, and participation rates were compared. RESULTS: Pairwise agreement between self- and clinician-collected samples was high by both Hybrid Capture 2 (90.8% agreement, kappa = 0.7) and PCR (92.6% agreement, kappa = 0.8), with significantly increased high-risk HPV detection in clinician-collected specimens (McNemar's P < 0.01). Ability to detect precursor lesions was highest by PCR testing of clinician-collected samples and lowest by Hybrid Capture 2 testing of self-collected samples (11 of 11 and 9 of 11 cases of cervical intraepithelial neoplasia grade 2/3 and cancer detected, respectively). Participation in home-based screening was significantly higher than clinic-based screening (71.5% and 53.8%, respectively; P < 0.001) among women ages 30 to 45 years. CONCLUSION: The combination of improved screening coverage and a high single test sensitivity afforded by HPV DNA testing of home-based self-collected swabs may have a greater programmatic effect on cervical cancer mortality reduction compared with programs requiring a pelvic exam.

BACKGROUND: Dengue surveillance data in India are limited and probably substantially underestimate the burden of disease. A community-based study was undertaken to assess the prevalence of dengue-specific immunoglobulin G (IgG) antibodies in children across India and to examine historical dengue exposure rates. Potential associations between socio-economic factors and dengue seroprevalence were also assessed (registered at ctri.nic.in: CTRI/2011/12/002243). METHODS: A convenience sample of 2609 healthy children aged 5-10 years was enrolled; these children were registered at or were living in the vicinity of eight centres located at six geographically distinct sites across India. Blood samples were drawn to test for the presence of dengue IgG antibodies using ELISA. Serotype-specific neutralizing antibody titres were measured in dengue IgG-positive children using dengue plaque reduction neutralization tests. Socio-demographic and household information was collected using a questionnaire. RESULTS: Overall, 2558/2609 children had viable samples with laboratory results for dengue IgG. Dengue IgG seroprevalence across all sites was 59.6% (95% confidence interval 57.7-61.5%): the lowest (23.2%) was in Kalyani, West Bengal, and the highest (80.1%) was in Mumbai. Seroprevalence increased with age. Multivariate analysis suggested associations with household water storage/supply and type of housing. Half of the subjects with positive IgG results presented a multitypic profile, indicating previous exposure to more than one serotype. CONCLUSIONS: The overall dengue seroprevalence suggests that dengue endemicity in India is comparable to that in highly endemic countries of Southeast Asia. Additional prospective studies are required to fully quantify the disease burden, in order to support evidence-based policies for dengue prevention and control in India.

BACKGROUND: Acute diarrhea accounts for a huge burden of infectious diseases in under-five children. OBJECTIVE: This systematic review was carried out to study the prevalence and associated risk factors of diarrhea among Indian children aged <5 years. METHODS: Papers were identified by a comprehensive electronic search of relevant medical subject heading (MeSH) terms in PubMed. Identified articles were independently reviewed against inclusion/exclusion criteria and rated for quality. 15 articles were abstracted and reviewed to identify the reported prevalence and risk factors for childhood diarrhea. Meta-analysis was done for calculating the pooled prevalence of diarrhea and point estimates of risk factors using random effects model with use of appropriate population weights, and depicted using forest plot. RESULTS: The overall prevalence of diarrhea between 2002 and 2013 was 21.70% (95% confidence interval [CI]: 11.24-34.46). The significantly associated risk factors were malnutrition (odds ratio [OR]: 1.73, 95% CI: 1.53-1.96) and anemia (OR: 1.71, 95% CI: 1.29-2.28) in child, and low socioeconomic status (OR: 7.14, 95% CI: 2.19-23.32). Age of the child <24 months, not breastfeeding, mothers' low literacy status and untreated drinking water did not show a significant association. Sex of the child, religion, higher education of mothers, and seasonality were found to be inconsistently associated in single studies. CONCLUSION: It was concluded that there is sufficient evidence on the association of childhood diarrhea with socio-demographic factors, but evidence on other contributory factors including breastfeeding and vaccination is inconclusive. There is need to conduct more analytical studies on lesser known risk factors of diarrhea to establish their risk factors in Indian children.

BACKGROUND: Renal dysfunction, increased xanthine oxidase activity and oxidative stress in placenta contributes to the elevated uric acid levels in preeclampsia (PE). OBJECTIVE: To determine serum uric acid and creatinine in hypertensive disorders of pregnancy and correlate with fetal outcome. MATERIALS AND METHODS: Pregnant women ≥32 weeks of gestation. Study population included 3 groups, 31 normotensive pregnant (NP) women as controls, 30 pregnant women with gestational hypertension (GH) and 30 with PE. RESULT: =0.87). CONCLUSION: Serum uric acid is a better diagnostic and predictive marker for PE and fetal outcome respectively.

We found a large number of false-positive readings by visual inspection with acetic acid (VIA) in a study of cervical cancer screening strategies (VIA, human papillomavirus HPV DNA testing, and Pap cytology) in a periurban community in Andhra Pradesh, India. We evaluated whether these false-positive readings might be occurring as a result of infections with Epstein-Barr virus (EBV) or cytomegalovirus (CMV), prevalent latent herpesviruses known to be shed from the female genital tract. While we found that there was no association between VIA results and the presence of EBV or CMV in the cervix, we did find a high prevalence of both viruses: 20% for EBV and 26% for CMV. In multivariate analyses, CMV prevalence was associated with younger age, lack of running water in the home, and visually apparent cervical inflammation. EBV prevalence was associated with older age and a diagnosis of cervical intraepithelial neoplasia grade 1 or greater. The biological and clinical implications of these viruses at the cervix remain to be determined. The strong association between the presence of EBV and cervical disease warrants future exploration to determine whether EBV plays a causal role in disease development or if it is merely a bystander in the process.

OBJECTIVES: Objectives were to study prevalence of frailty among Indian oldest old population, and to detect its correlates. METHODS: A cross sectional community based study was done including 200 healthy participants aged ≥80 years, randomly sampled from Hyderabad city in India. They completed an administered questionnaire and physical function tests including SPPB, grip strength. Cognitive function was assessed using MMSE and depression using GDS. Blood pressure, haemoglobin, and fasting blood sugar were measured for all participants. Frailty was defined using Fried phenotype criteria. Logistic regression was done to identify independently associated correlates. RESULTS: The prevalence of frailty syndrome was 83.4% in our study population. Frailty among men was 80.3% and among women was 84.7%, and it increased with increasing age. The independent correlates which increased the odds of frailty were poor physical performance (SPPB) (OR: 4.21; 95% CI: 1.12-15.83), depression (OR: 3.35; 95% CI: 1.29-8.73), chronic joint pains (OR: 4.90; 95% CI: 1.97-12.18) and COPD (OR: 3.01; 95% CI: 1.03- 8.78), while hypertension showed inverse association (OR: 0.33;95% CI: 0.11-0.94). CONCLUSION: The prevalence of frailty among the oldest old is very high. Geriatric medicine protocols must include routine screening for frailty, while also including early detection of poor physical performance, depression, COPD and osteoarthritis.

BACKGROUND: Coronary artery disease (CAD) is the leading cause of morbidity and mortality in patients with type 2 diabetes mellitus (T2DM). The purpose of the present study was to discriminate the Indian CAD patients with or without T2DM by using multiple pathophysiological biomarkers. METHODS: Using sensitive multiplex protein assays, we assessed 46 protein markers including cytokines/chemokines, metabolic hormones, adipokines and apolipoproteins for evaluating different pathophysiological conditions of control, T2DM, CAD and T2DM with CAD patients (T2DM_CAD). Network analysis was performed to create protein-protein interaction networks by using significantly (p < 0.05) altered protein markers in each disease using STRING 10.5 database. We used two supervised analysis methods i.e., between class analysis (BCA) and principal component analysis (PCA) to reveals distinct biomarkers profiles. Further, random forest classification (RF) was used to classify the diseases by the panel of markers. RESULTS: Our two supervised analysis methods BCA and PCA revealed a distinct biomarker profiles and high degree of variability in the marker profiles for T2DM_CAD and CAD. Thereafter, the present study identified multiple potential biomarkers to differentiate T2DM, CAD, and T2DM_CAD patients based on their relative abundance in serum. RF classified T2DM based on the abundance patterns of nine markers i.e., IL-1β, GM-CSF, glucagon, PAI-I, rantes, IP-10, resistin, GIP and Apo-B; CAD by 14 markers i.e., resistin, PDGF-BB, PAI-1, lipocalin-2, leptin, IL-13, eotaxin, GM-CSF, Apo-E, ghrelin, adipsin, GIP, Apo-CII and IP-10; and T2DM _CAD by 12 markers i.e., insulin, resistin, PAI-1, adiponectin, lipocalin-2, GM-CSF, adipsin, leptin, Apo-AII, rantes, IL-6 and ghrelin with respect to the control subjects. Using network analysis, we have identified several cellular network proteins like PTPN1, AKT1, INSR, LEPR, IRS1, IRS2, IL1R2, IL6R, PCSK9 and MYD88, which are responsible for regulating inflammation, insulin resistance, and atherosclerosis. CONCLUSION: We have identified three distinct sets of serum markers for diabetes, CAD and diabetes associated with CAD in Indian patients using nonparametric-based machine learning approach. These multiple marker classifiers may be useful for monitoring progression from a healthy person to T2DM and T2DM to T2DM_CAD. However, these findings need to be further confirmed in the future studies with large number of samples.

Agriculture plays a very vital role in every individual life. Without food there exists no life in this world. For that to happen, proper yield of crops is necessary. But these days getting proper yield of crops is a tough task as they are affected with some diseases during their growth and sometimes it remains unnoticed by the farmer and this in turn results in the un-proper yield of crops. This paper focuses upon detection of such diseases which occur on a paddy crop using the concept of artificial intelligence and CNN. The diseases encountered by a paddy crop is stored in the database i.e., raspberry pi and when the farmer clicks the photo of the crop, the pi analyzes that picture and compares with the database pictures using the concepts of convolutional neural network and artificial intelligence and thus depicts the output whether the crop is affected with a particular or not and thus finally alerts the farmer about the disease.

BACKGROUND: Awareness regarding fever is reportedly low among Indian urban parents, leading to its over- management among under five children. We attempted to study the awareness and fever management practices of South Indian urban parents. The objectives were to find the awareness of parents regarding childhood fever management, and correlates of practices. METHODS: One hundred parents of under-five children with history of fever in past three months were randomly selected and interviewed using a predesigned tool. Children's weight and height was measured. Awareness scores for causes of fever and fever management were constructed. Logistic regression was done to identify correlates of incorrect practices. RESULTS: 95% parents were aware about correct temperature above which fever became harmful. Awareness score for causes of fever was poor (<1) among 41% parents. Mothers' complications awareness scores were better than fathers (p<0.05). 81% parents used antibiotics; only 18% consulted a doctor before doing so. 17% parents using antibiotics did not complete the prescribed course. The independent correlates of poor fever management practices were working parents (OR: 6.28; 95%CI: 1.7-23.16), lesser number of children (OR: 3.08; 95%CI: 1.01-9.37), poor compliance for antipyretics (OR: 9.20; 95%CI: 1.64-51.52) and giving antipyretics without consulting doctors (OR: 5.43; 95%CI: 1.69-17.47). Poor knowledge of available pediatric antipyretic preparations was negatively correlated (OR: 0.13; 95%CI: 0.02-0.64). CONCLUSION: Fever awareness was fair among urban parents. Mothers had better awareness than fathers. Increased awareness for correct fever management of under-five children is desirable among urban parents to reduce misuse of antibiotics and antipyretics.

The southern state of Andhra Pradesh (AP) has one of the highest rates of HIV-1 infection in India. Estimates of HIV infection in rural areas have begun to approximate the urban. Methods of HIV transmission in rural India are poorly understood. We examined risk factors for HIV transmission in a group of rural villages in AP through the use of a sexual-network analysis survey - the Indian Health and Family Life Survey (IHFLS). The study sample included 20 HIV-positive and 40 HIV-negative matched controls randomly selected from a population-based, voluntary counselling and testing program in rural AP. HIV-1 status was confirmed by Western Blot. The 405-item IHFLS is based upon the National Health and Life Survey which has been validated in the US and China. The sample mean age was 37 years and 22% were of a tribal caste. Among female respondents, none were commercial sex workers (CSWs) and there were no significant social or behavioral associations with HIV infection. Among male respondents, ever having bought sex and having more than one lifetime partner were found to be significantly associated with HIV infection (p=0.002 and p=0.017). Amongst sub-populations, all men who had sex with men (MSM) were married. Tribals were more likely to report a concurrent sexual relationship (p=0.04). All high-risk men, including MSM, men who buy sex and men with multiple lifetime female partners did not use condoms. Public health interventions aimed at reducing HIV transmission in rural AP should consider targeting sub-populations of men who engage in covert MSM or CSW, high-risk tribal caste members and at-risk wives.

OBJECTIVES: We aimed to determine the feasibility and effectiveness of an intervention anchored on mHealth and task sharing strategy of involving non-physician health workers (NPHW) on population level detection, treatment and control of hypertension and diabetes in India. METHODS: Non-physician health workers (NPHWs) equipped with tablet computers that were linked with point-of-care devices for blood pressure (BP) and blood sugar measurements visited households, screened adult individuals for hypertension and diabetes from two randomly selected villages in the Medchal district, Telangana, India. Further, they digitally connected those individuals with hypertension and diabetes to a study physician via Skype, and handed over a printed e-prescription. Medication adherence checks, BP and fasting blood sugar measurements were done once a month and doctor consultations once in three months during follow-up. RESULTS: Among 2456 eligible individuals, 1751 and 1686 individuals were screened for hypertension and diabetes, respectively. Prevalence of hypertension was 23·6% (95% CI 21·6%-25·6%) and among them 38.9% were newly detected. Prevalence of diabetes was 11·2% (9·7%-12·7%) and 28.6% of them were newly detected. After 24 months of intervention, control of BP and blood sugar was achieved in 54.0% and 34·1% of individuals with hypertension and diabetes, respectively. Blood pressure control rate improved by 12% (7.9%-16.0%) in known hypertensive individuals over the intervention period. INTERPRETATION: This research demonstrates the feasibility and local acceptability of a mHealth intervention strategy anchored on NPHWs guided by physicians for detection, treatment and regular follow-up of individuals with hypertension and diabetes in a community setting in India.

BACKGROUND: Hypertensive disorders are the most common in pregnancy. Several studies showed a positive correlation between elevated maternal serum uric acid (UA), serum creatinine and adverse maternal and fetal outcomes, but only a few studies are available on serum cystatin C and maternal and fetal outcomes. The present study was undertaken to study the association of serum UA, creatinine and cystatin C with maternal and fetal outcomes. METHODS: Out of 116 pregnant women 69 women had no hypertension and 47 had hypertension with or without proteinuria. Serum UA, creatinine and cystatin C was measured by modified Uricase method, modified kinetic Jaffe's reaction and particle-enhanced immunonephelometric assay respectively. Multivariate logistic regression was performed to determine the independent effects of serum UA, creatinine and cystatin C on maternal and fetal outcomes using stata 13.1. RESULTS: The adjusted odds ratio (OR) was 3.73 (95% CI: 1.18-11.75; P=0.024) for UA; 15.79 (95% CI: 3.04-81.94; P=0.001) for creatinine and 2.03 (95% CI: 0.70-5.87; P=0.192) for cystatin C in hypertensive disorders of pregnancy. All the three renal parameters were not significantly associated with birth weight, gestational age of delivery and mode of delivery after adjusting for the confounding factors. CONCLUSIONS: Serum creatinine and uric acid are independent risk factors for hypertensive disorders of pregnancy. High serum uric acid is associated with low birth weight and delivery by caesarian section whereas high serum creatinine with preterm delivery only before adjustment for confounding factors and not after adjustment. Serum cystatin C was not significantly associated with the maternal and fetal outcomes.
