    Aim: Despite the endemicity of typhoid in Kelantan, epidemiological data showing typhoid association to age, sex,ethnicity and district of patients is limited. This retrospective study investigated the statistical association of thesevariables from a retrieved registry.Methodology and results: Cross-tabulation using SPSS was used to analyze 1394 cases of confirmed typhoid patientsadmitted to various hospitals in Kelantan state over a six-year period. Fourteen age groups with a five-year rangeinterval were generated. There was a significant association between typhoid infection and sex of subjects, wherebyfemales were generally more susceptible than males. Ethnicity and district of typhoid patients did not show significantassociation.Conclusion, significance and impact of study: The observation of an increased number of typhoid cases with a malepredominance in the age group 5-14 and female predominance in the 20-60 age group calls for improved hygiene,continued public health education, together with better laboratory diagnostics to identify carriers, are some measures tocontrol this disease

    Daily nevirapine (NVP) prophylaxis to HIV-exposed infants significantly reduces breast-milk HIV transmission. We assessed NVP-resistance in Indian infants enrolled in the "six-week extended-dose nevirapine" (SWEN) trial who received single-dose NVP (SD-NVP) or SWEN for prevention of breast-milk HIV transmission but who also acquired subtype C HIV infection during the first year of life.Standard population sequencing and cloning for viral subpopulations present at > or =5% frequency were used to determine HIV genotypes from 94% of the 79 infected Indian infants studied. Timing of infection was defined based on when an infant's blood sample first tested positive for HIV DNA. SWEN-exposed infants diagnosed with HIV by six weeks of age had a significantly higher prevalence of NVP-resistance than those who received SD-NVP, by both standard population sequencing (92% of 12 vs. 38% of 29; p = 0.002) and low frequency clonal analysis (92% of 12 vs. 59% of 29; p = 0.06). Likelihood of infection with NVP-resistant HIV through breast-milk among infants infected after age six weeks was substantial, but prevalence of NVP-resistance did not differ among SWEN or SD-NVP exposed infants by standard population sequencing (15% of 13 vs. 15% of 20; p = 1.00) and clonal analysis (31% of 13 vs. 40% of 20; p = 0.72). Types of NVP-resistance mutations and patterns of persistence at one year of age were similar between the two groups. NVP-resistance mutations did differ by timing of HIV infection; the Y181C variant was predominant among infants diagnosed in the first six weeks of life, compared to Y188C/H during late breast-milk transmission.Use of SWEN to prevent breast-milk HIV transmission carries a high likelihood of resistance if infection occurs in the first six weeks of life. Moreover, there was a continued risk of transmission of NVP-resistant HIV through breastfeeding during the first year of life, but did not differ between SD-NVP and SWEN groups. As with SD-NVP, the value of preventing HIV infection in a large number of infants should be considered alongside the high risk of resistance associated with extended NVP prophylaxis.ClinicalTrials.gov NCT00061321

    Endophytes vs tree pathogens and pests: can they be used as biological control agents to improve tree health?

    Like all other plants, trees are vulnerable to attack by a multitude of pests and pathogens. Current control measures for many of these diseases are limited and relatively ineffective. Several methods, including the use of conventional synthetic agro-chemicals, are employed to reduce the impact of pests and diseases. However, because of mounting concerns about adverse effects on the environment and a variety of economic reasons, this limited management of tree diseases by chemical methods is losing ground. The use of biological control, as a more environmentally friendly alternative, is becoming increasingly popular in plant protection. This can include the deployment of soil inoculants and foliar sprays, but the increased knowledge of microbial ecology in the phytosphere, in particular phylloplane microbes and endophytes, has stimulated new thinking for biocontrol approaches. Endophytes are microbes that live within plant tissues. As such, they hold potential as biocontrol agents against plant diseases because they are able to colonize the same ecological niche favoured by many invading pathogens. However, the development and exploitation of endophytes as biocontrol agents will have to overcome numerous challenges. The optimization and improvement of strategies employed in endophyte research can contribute towards discovering effective and competent biocontrol agents. The impact of environment and plant genotype on selecting potentially beneficial and exploitable endophytes for biocontrol is poorly understood. How endophytes synergise or antagonise one another is also an important factor. This review focusses on recent research addressing the biocontrol of plant diseases and pests using endophytic fungi and bacteria, alongside the challenges and limitations encountered and how these can be overcome. We frame this review in the context of tree pests and diseases, since trees are arguably the most difficult plant species to study, work on and manage, yet they represent one of the most important organisms on Earth

    Across thenation, the demand for energy is outpacing supply. Whereas the generation of Electricityis limited. Hence the effective management of existing energy generation is essential.You cannot manage what you cannot measure.Energy monitoring serves an effective guidance for energy management. The system discussed in the paper monitors and controlsthe electrical appliances.Electrical appliances (e.g.,T.V. fan, air conditioning units, heating appliances, bulbs) can be monitored and controlled using IOT technology from overall the world. The system includes a smart device application, a cloud-based database, an Application Programming Interface (API) and a hardware development is proposed. The usage energy data from each unit to be controlled and storedin a cloud based database that can be analysesand recorded for energy conservation and analysis.On the other hand, Governmentelectricity revenue is worm-eatenby power theft, incorrect meter reading and billing.

    The development of mental health services within primary care in India: learning from oral history.

    BACKGROUND: In India very few of those who need mental health care receive it, despite efforts of the 1982 National Mental Health Programme and its district-level component the District Mental Health Programme (DMHP) to improve mental health care coverage. AIMS: To explore and unpack the political, cultural and other historical reasons for the DMHP's failures and successes since 1947 (post-independence era), which may highlight issues for today's current primary mental health care policy and programme. METHODS: Oral history interviews and documentary sourcing were conducted in 2010-11 with policy makers, programme managers and observers who had been active in the creation of the NMHP and DMHP. RESULTS: The results suggest that the widely held perception that the DMHP has failed is not entirely justified, insofar that major hurdles to the implementation of the plan have impacted on mental health coverage in primary care, rather than faults with the plan itself. These hurdles have been political neglect, inadequate leadership at central, state and district levels, inaccessible funding and improperly implemented delivery of services (including poor training, motivation and retention of staff) at district and community levels. CONCLUSION: At this important juncture as the 12th Five Year Plan is in preparation, this historical paper suggests that though the model may be improved, the most important changes would be to encourage central and state governments to implement better technical support, access to funds and to rethink the programme leadership at national, state and district levels
