BACKGROUND: Medication use is high among nursing home (NH) residents, but there is a lack of longitudinal studies, determining medication use at admission and its evolution over time. AIM: Describing the evolution of the medication use two years after entering a NH, compared to the baseline observations and exploring the relation to the physical and mental health. METHODS: Data from the observational prospective Ageing@NH study, based on an inception cohort of newly admitted residents at NHs (65+) was used, selecting those consenting and with medication chart available...

The present longitudinal study included different school readiness factors measured in kindergarten with the aim to predict later academic achievement in second grade. Based on data of N = 134 children, the predictive power of executive functions, visual-motor coordination and physical fitness on later academic achievement was estimated using a latent variable approach. By entering all three predictors simultaneously into the model to predict later academic achievement, significant effects of executive functions and visual-motor coordination on later academic achievement were found...

Pathogenic fungi express fatty acid dioxygenases (DOX) fused to cytochromes P450 with diol or allene oxide synthase activities. The orientation of the fatty acids in the active sites of DOX was investigated with amino acid conjugates of 18:3n-3 and 18:2n-6. 9S-DOX-allene oxide synthase (AOS) oxidized the Gly, Ile, and Trp derivatives at C-9, which suggests that these conjugates enter the substrate recognition site with the omega end in analogy with fatty acids bound to cyclooxygenases and coral 8R-lipoxygenase (8R-LOX)...

Molecular dynamics simulations are used to study the dissolution of water into an adjacent, immiscible organic liquid phase. Equilibrium thermodynamic and structural properties are calculated during the transfer of water molecule(s) across the interface using umbrella sampling. The net free energy of transfer agrees reasonably well with experimental solubility values. We find that water molecules "prefer" to transfer into the adjacent phase one-at-a-time, without co-transfer of the hydration shell, as in the case of evaporation...

BACKGROUND: Thousands of individuals with Parkinson's disease (PD) in low-income countries have limited access to marketed levodopa preparations. Mucuna pruriens (MP), a levodopa-containing leguminous plant growing in tropical areas, may be a sustainable alternative therapy for indigent patients. Single-dose intake of MP proved noninferior to marketed levodopa preparations. METHODS: Fourteen PD patients with motor fluctuations and dyskinesias received MP powder (obtained from roasted seeds) and marketed levodopa/carbidopa (LD/CD) in a randomized order and crossover design over a 16-week period...

BACKGROUND: Cervical cancer is the second most prevalent cancer among women in the developing countries including Ethiopia. Precancerous lesions can be developed and risk to the development of cervical cancer over time. Early identification of the precancerous lesion and its risk factor is paramount in preventing cervical cancer. However, the determinants of cervical precancerous lesions are not well documented in Ethiopia. Therefore, this study is conducted to determine factors associated with cervical precancerous lesion among women screened for cervical cancer...

Campylobacter jejuni was longitudinally isolated from beef cattle housed in four confined feeding operations (CFOs) in southern Alberta over 18 months. All of the cattle were administered a variety of antimicrobial agents (AMAs) non-therapeutically and metaphylactically during their time in the CFOs. In total, 7966 C. jejuni isolates were recovered from cattle. More animals were colonized by the bacterium after >60 days in the CFO (i.e. interim) compared to individuals upon entry at the CFO (i.e. arrival)...

Chronic, biofilm-based bacterial infections are exceptionally difficult to eradicate due to the high degree of antibiotic recalcitrance exhibited by cells in biofilm communities. In the opportunistic pathogen Pseudomonas aeruginosa, biofilm recalcitrance is multifactorial and arises in part from the preferential expression of resistance genes in biofilms compared to exponential phase planktonic cells. One such mechanism involves ndvB, which we have previously shown to be expressed specifically in biofilms. In this study, we investigated the regulatory basis of this lifestyle-specific expression by developing an unstable GFP transcriptional reporter to observe the expression pattern of ndvB We found that, in addition to its expression in biofilms, ndvB was also upregulated in planktonic cells as they enter stationary phase...

Pyrrolizidine alkaloids (PAs) are extensively synthesized by plants and are commonly present in herbs and foodstuffs, which exhibit hepatotoxicity requiring metabolic activation by cytochrome P450 (CYP) 3A to form the electrophilic metabolites-pyrrolic ester. PAs also cause embryo toxicity, but the metabolic profiles of PAs in fetus and placenta have been far from clear. In this study, we determined the basal metabolic activation of retrorsine (RTS) in rat maternal liver, placenta and fetal liver in vitro, and examined the fetal toxicity and bioactivation of RTS in vivo...

A 45-year-old man was presented at the emergency department with altered neurological status and a 1-day history of diarrhoea and fever. The patient's sexual history revealed multiple male partners. As bacterial meningitis or viral encephalitis was suspected, treatment was started accordingly. Cerebrospinal fluid investigations only showed a slight increase of leucocytes, and microbiological studies remained negative. Stool culture revealed Shigella flexneri, after which Shigella-associated encephalopathy was suspected...

BACKGROUND: Mental health is a growing concern among older people all over the world. China has a rapidly aging population, and the number of elderly empty-nesters, who have no children or whose children have already left home, is on the rise. These older adults live alone or with a spouse. Therefore, we should be concerned about these empty-nester, especially their mental health, due to its vital role. METHODS: This cross-sectional study was performed from March to December 2015...

BACKGROUND: Gut dysbiosis is observed in several neuropsychiatric disorders exhibiting increases in anxiety behavior, and recent work suggests links between gut inflammation and such disorders. One source of this inflammation may be lipopolysaccharide (LPS), a toxic component of gram-negative bacteria. Here, we (1) determine whether oral gavage of LPS, as a model of gut-derived endotoxemia, affects anxiety-like and/or repetitive behaviors; (2) test whether these changes depend on TLR4 signaling; and (3) test the extent to which gut-derived endotoxin and TLR4 antagonism affects males and females differently...

Reproductive abnormalities are included as health complications in offspring exposed to poor prenatal nutrition. We have previously shown in a rodent model, that offspring born to nutrient restriction during pregnancy are born small, enter puberty early, and display characteristics of early ovarian aging as adults. The present study investigated whether key proteins involved in follicle recruitment and growth mediate ovarian follicle loss. Pregnant rats were randomized to: a standard diet throughout pregnancy and lactation (CON), or a calorie-restricted (50% of control) diet (UN) during pregnancy...

BACKGROUND: There is minimal evidence on the extent to which the occurrence of a severe acute exacerbation of COPD that results in hospitalization affects the subsequent disease course. Previous studies on this topic did not generate causally-interpretable estimates. Our aim was to use corrected methodology to update previously reported estimates of the associations between previous and future exacerbations in these patients. METHODS: Using administrative health data in British Columbia, Canada (1997-2012), we constructed a cohort of patients with at least one severe exacerbation, defined as an episode of inpatient care with the main diagnosis of COPD based on international classification of diseases (ICD) codes...
