Dengue Outbreaks

Dengue is unquestionably one of the biggest health concerns in India and for many other developing countries. Unfortunately, many people have lost their lives because of it. Every year, approximately 390 million dengue infections occur around the world among which 500,000 people are seriously infected and 25,000 people have died annually. Many factors could cause dengue such as temperature, humidity, precipitation, inadequate public health, and many others. In this paper, we are proposing a method to perform predictive analytics on dengue’s dataset using KNN: a machine-learning algorithm. This analysis would help in the prediction of future cases and we could save the lives of many.

Gendered Stereotypes

Background: Marketing of food supplements in Greece in print media has not been examined and this study is the first attempt to provide a comparative statistical analysis. Methods: Lifestyle magazines that were distributed all over Greece and aimed at women and men were collected in the years 2014 and 2016. Five criteria with their subcriteria were developed and were related to the branding of the food supplements; their quality characteristics; the information given about health concerns; photographs of people who promoted food supplements and to claims of their suitability. Results: It seems that in terms of product branding, women’s magazines were more likely to be targeted. Some quality characteristics such as information about the ingredients of food supplements or information about banned substances were more likely to be seen in women’s magazines in 2016. In 2014 and 2016, not all advertisements provided information about health concerns and among those which informed readers about health concerns, differentiation in target audiences was observed. Photographs that showed people promoting food supplements as well as claims of suitability for various categories of consumers, seem to be gendered in 2014 but this trend was not strong enough in 2016. Conclusion: It can be argued that the marketing of food supplements was aggressive and gendered in 2014 and changed in 2016 with better information on public health but had retained some gendered stereotypes.

This chapter introduces ethical issues that arise in the context of biosecurity: policies and actions intended to prevent the development or emergence, or mitigate the consequences, of serious biological threats. These threats could include deliberate biological weapon attacks (bioterrorism), pandemics, emerging infectious diseases, or major laboratory accidents. The basic values that underpin these public health concerns are first introduced. Ethical issues that arise before, during, and following a biosecurity crisis are then examined, including issues of resource allocation, dual-use research, and the possibility of quarantine. Their resolution requires trade-offs among different ethical values, including utility, fairness, and liberty.

Salmonellosis caused by non-typhoidal Salmonellaenterica from poultry products is a major public health concern worldwide. This study aimed at estimating the pathogenicity and antimicrobial resistance in S. enterica isolates obtained from poultry birds and their food products from different areas of Pakistan. In total, 95/370 (25.67%) samples from poultry droppings, organs, eggs, and meat were positive for Salmonella. The isolates were further identified through multiplex PCR (mPCR) as Salmonella Typhimurium 14 (14.7%), Salmonella Enteritidis 12 (12.6%), and other Salmonella spp. 69 (72.6%). The phenotypic virulence properties of 95 Salmonella isolates exhibited swimming and/or swarming motility 95 (100%), DNA degrading activity 93 (97.8%), hemolytic activity 92 (96.8%), lipase activity 87 (91.6%), and protease activity 86 (90.5%). The sopE virulence gene known for conferring zoonotic potential was detected in S. Typhimurium (92.8%), S. Enteritidis (100%), and other Salmonella spp. (69.5%). The isolates were further tested against 23 antibiotics (from 10 different antimicrobial groups) and were found resistant against fifteen to twenty-one antibiotics. All isolates showed multiple drug resistance and were found to exhibit a high multiple antibiotic-resistant (MAR) index of 0.62 to 0.91. The strong biofilm formation at 37 °C reflected their potential adherence to intestinal surfaces. There was a significant correlation between antimicrobial resistance and the biofilm formation potential of isolates. The resistance determinant genes found among the isolated strains were blaTEM-1 (59.3%), blaOxA-1 (18%), blaPSE-1 (9.5%), blaCMY-2 (43%), and ampC (8.3%). The detection of zoonotic potential MDR Salmonella in poultry and its associated food products carrying cephalosporin and quinolone resistance genes presents a major threat to the poultry industry and public health.

Hurricanes Katrina And Rita

AbstractIntroduction:During 2005, Hurricanes Katrina and Rita struck the US Gulf Coast, displacing approximately two million people. With >250,000 evacuees in shelters, volunteers from the American Red Cross (ARC) and other nongovernmental and faith-based organizations provided services. The objective of this study was to evaluate the composition, pre-deployment training, and recognition of scenarios with outbreak potential by shelter health staff.Methods:A rapid assessment using a 36-item questionnaire was conducted through in-person interviews with shelter health staff immediately following Hurricanes Katrina and Rita. Data were collected by sampling at shelters located throughout five ARC regions in Texas. The survey focused on: (1) public health capacity; (2) level of public health awareness among staff; (3) public health training prior to deployment; and (4) interest in technical support for public health concerns. In addition, health staff volunteers were asked to manage 11 clinical scenarios with possible public health implications.Results:Forty-three health staff at 24 shelters were interviewed. Nurses comprised the majority of shelter health volunteers and were present in 93% of shelters; however, there were no public health providers present as staff in any shelter. Less than one-third of shelter health staff had public health training, and only 55% had received public health information specific to managing the health needs of evacuees. Only 37% of the shelters had a systematic method for screening the healthcare needs of evacuees upon arrival. Although specific clinical scenarios involving case clusters were referred appropriately, 60% of the time, 75% of all clinical scenarios with epidemic potential did not elicit proper notification of public health authorities by shelter health staff. In contrast, clinical scenarios requiring medical attention were correctly referred >90% of the time. Greater access and support from health and public health experts was endorsed by 93% of respondents.Conclusions:Public health training for sheltering operations must be enhanced and should be a required component of pre-deployment instruction. Development of a standardized shelter intake health screening instrument may facilitate assessment of needs and appropriate resource allocation. Shelter health staff did not recognize or report the majority of cases with epidemic potential to public health authorities. Direct technical support to shelter health staff for public health concerns could bridge existing gaps and assist surveillance efforts.

Worker Health

Routine office or computer work are of public health concerns due to their sedentary nature. Sit- stand desks may be prescribed for employees based on medical or ergonomic factors. Sit-stand or active workstations, either assigned to individual workers or made available in “unassigned” office areas are also making inroads into the workplace with the goal of reducing sedentary work, varying (alternating) work postures, improving productivity, or accommodating workers with musculoskeletal symptoms. This diverse panel will present recent research and practice findings and invite audience participation in a discussion of this trending topic. Studies examining the effects of sit-stand or active workstations on physiological and cardiovascular outcomes will be reported. The effects on movement patterns, performance and productivity will also be examined. Real workplace interventions and examples of practices will be presented. The goal is to provide a forum to share our understanding about the benefits and limitations of various office workstation designs and discuss research needs.

Usutu virus (USUV) is a flavivirus that mainly infects wild birds through the bite of Culex mosquitoes. Recent outbreaks have been associated with an increased number of cases in humans. Despite being a growing source of public health concerns, there is yet insufficient data on the virus or host cell targets for infection control. In this work we have investigated whether the cellular kinase Akt and USUV polymerase NS5 interact and co-localize in a cell. To this aim, we performed co-immunoprecipitation (Co-IP) assays, followed by confocal microscopy analyses. We further tested whether NS5 is a phosphorylation substrate of Akt in vitro. Finally, to examine its role in viral replication, we chemically silenced Akt with three inhibitors (MK-2206, honokiol and ipatasertib). We found that both proteins are localized (confocal) and pulled down (Co-IP) together when expressed in different cell lines, supporting the fact that they are interacting partners. This possibility was further sustained by data showing that NS5 is phosphorylated by Akt. Treatment of USUV-infected cells with Akt-specific inhibitors led to decreases in virus titers (>10-fold). Our results suggest an important role for Akt in virus replication and stimulate further investigations to examine the PI3K/Akt/mTOR pathway as an antiviral target.
