Microbial food-borne diseases are still frequently reported despite the implementation of microbial quality legislation to improve food safety. Among all the microbial agents, viruses are the most important causative agents of food-borne outbreaks. The development and application of a new generation of sequencing techniques to test for viral contaminants in fresh produce is an unexplored field that allows for the study of the viral populations that might be transmitted by the fecal-oral route through the consumption of contaminated food...

BACKGROUND: No clear association between hepatitis B virus (HBV) infection and atopic dermatitis (AD) has been established. Some studies have reported that subjects with HBV had an increased risk of atopy; other studies reported an inverse association between HBV seropositivity and allergic diseases. OBJECTIVE: We evaluated the association between AD and hepatitis B antigen (HBsAg) positivity using Korean National Health and Nutrition Examination Survey data. METHODS: In total, 14,776 participants aged > 19 years were included in the analysis...

Escherichia coli ordinarily resides in the lower gastrointestinal tract in humans, but some strains, known as Uropathogenic E. coli (UPEC), are also adapted to the relatively harsh environment of the urinary tract. Infections of the urine, bladder and kidneys by UPEC may lead to potentially fatal bloodstream infections. To survive this range of conditions, UPEC strains must have broad and flexible metabolic capabilities and efficiently utilize scarce essential nutrients. Whole-organism (or "omics") methods have recently provided significant advances in our understanding of the importance of metabolic adaptation in the success of UPECs...

OBJECTIVE: Rheumatoid arthritis (RA) is clinically an undulant disease, and reasons for flare or remission vary. We aimed to identify factors potentially associated with disease flare and remission. MATERIAL AND METHODS: Two hundred and seventy-four patients with RA who were admitted to our center between January 2010 and January 2016 were included. Disease activity was evaluated using disease activity score 28 (DAS 28); functional status was evaluated using the modified Health Assessment Questionnaire (m-HAQ), a questionnaire that comprises flare or remission domains such as psychological stress and mood status, physical trauma, nutrition regimen, infection, antibiotic use, and seasonal weather changes...

Several herbivorous insects and plant-associated microorganisms control the phytohormonal balance, thus enabling them to successfully exploit the plant by inhibiting plant defences and withdrawing plant resources for their own benefit. The leaf-mining moth Phyllonorycter blancardella modifies the cytokinin (CK) profile of mined leaf-tissues, and the insect symbiotic bacteria Wolbachia is involved in the plant manipulation to the benefit of the insect host. To gain a deeper understanding into the possible origin and dynamics of CKs, we conducted an extensive characterization of CKs in larvae and in infected apple leaves...

REVIEW
Cho Naing, Maxine A Whittaker
BACKGROUND: Pressure ulcers, also known as bed sores, pressure sores or decubitus ulcers develop as a result of a localised injury to the skin or underlying tissue, or both. The ulcers usually arise over a bony prominence, and are recognised as a common medical problem affecting people confined to a bed or wheelchair for long periods of time. Anabolic steroids are used as off-label drugs (drugs which are used without regulatory approval) and have been used as adjuvants to usual treatment with dressings, debridement, nutritional supplements, systemic antibiotics and antiseptics, which are considered to be supportive in healing of pressure ulcers...

BACKGROUND: Hyperspectral imaging is an emerging means of assessing plant vitality, stress parameters, nutrition status, and diseases. Extraction of target values from the high-dimensional datasets either relies on pixel-wise processing of the full spectral information, appropriate selection of individual bands, or calculation of spectral indices. Limitations of such approaches are reduced classification accuracy, reduced robustness due to spatial variation of the spectral information across the surface of the objects measured as well as a loss of information intrinsic to band selection and use of spectral indices...

Lijun Wang, Fang Tian
With the rapid development of critical care medicine (CCM) in China, there are increases in the number of intensive care units (ICUs), the scale of one center ICU and the team. Subspecialty construction of CCM is of great concerns for personnel training as well as discipline development, and is currently one of the urgent problems that need to be resolved. Experience of CCM subspecialty construction from Europe and the United States is lacking and it is necessary to propose some opinions on innovation to construct CCM subspecialties with Chinese characteristics...

BACKGROUND: With the increase in elderly population, life-threatening chronic diseases are increasing, simultaneously increasing the need for palliative care centers (PCCs). OBJECTIVES: To evaluate the factors affecting the length of stay (LOS) and discharge of patients from a PCC. METHODS: A retrospective scan was made of the records of patients followed up in the PCC between January 2013 and March 2016. A record was made of patient age, gender, diagnosis, conditions/comorbidities, Glasgow Coma Scale, Karnofsky Performance Scale, LOS, prognosis (exitus or surviving), percutaneous endoscopic gastrostomy (PEG), tracheostomy, mechanical ventilator, nutrition (total parenteral nutrition [TPN] or enteral nutrition), and the results of cultures taken during stay in PCCs (blood, tracheal aspirate, urine, rectal swab, wound)...

Bacterial obligate intracellular parasites are clinically significant animal and human pathogens. Central to the biology of these organisms is their level of adaptation to intracellular replication niches associated with physicochemical and nutritional constraints. While most bacterial pathogens can adapt to a wide range of environments, severe niche restriction-an inability to thrive in diverse environments-is a hallmark of bacterial obligate intracellular parasites. Herein the physicochemical and nutritional factors underlying the physiological basis for niche restriction in the zoonotic bacterial obligate intracellular parasite and Q fever agent Coxiella burnetii are characterized...

PURPOSE OF REVIEW: The aim of this study was to review the most recent aspects of nutrition and its impact on health-related quality of life (HRQOL) in patients with chronic hepatitis C (CHC). RECENT FINDINGS: Low HRQOL scores have been found in all stages of hepatitis C virus (HCV) infection. Of the factors linked to HRQOL, three aspects should be emphasized, nutritional status, physical activity and mental health status. Regarding the nutrition and metabolic conditions, a broad spectrum of nutritional disorders may impact on HRQOL of patients with CHC...
