Abstract
Glyphosate is used worldwide as a compound of pesticides and is detectable in many environmental compartments. It enters water bodies primarily through drift from agricultural areas so that aquatic organisms are exposed to this chemical, especially after rain events. Glyphosate is advertised and sold as a highly specific herbicide, which interacts with the EPSP synthase, an enzyme of the shikimate metabolism, resulting in inhibition of the synthesis of vital aromatic amino acids. However, not only plants but also bacteria can possess this enzyme so that influences of glyphosate on the microbiomes of exposed organisms cannot be excluded. Those influences may result in subtle and long-term effects, e.g., disturbance of the symbiotic interactions of bionts with microorganisms of their microbiomes. Mechanisms how the transformation product aminomethylphosphonic acid (AMPA) of glyphosate might interfere in this context have not understood so far. In the present study, molecular biological fingerprinting methods showed concentration-dependent effects of glyphosate and AMPA on fish microbiomes. In addition, age-dependent differences in the composition of the microbiomes regarding abundance and diversity were detected. Furthermore, the effect of exposure to glyphosate and AMPA was investigated for several fish pathogens of gut microbiomes in terms of their gene expression of virulence factors associated with pathogenicity. In vitro transcriptome analysis with the fish pathogen Yersinia ruckeri revealed that it is questionable whether the observed effect on the microbiome is caused by the intended mode of action of glyphosate, such as the inhibition of EPSP synthase activity.

Abstract
Recently, we predicted theoretically that in cavities that support several longitudinal modes, strong coupling can occur in very different manners, depending on the system parameters. Distinct longitudinal cavity modes are either entangled with each other via the material or independently coupled to the exciton mode. Here, we experimentally demonstrate the transition between those two regimes as the cavity thickness is gradually increased while maintaining fixed coupling strength. We study the properties of the system using reflection and emission spectroscopy and show that even though the coupling strength is constant, different behavior in the spectral response is observed along the coupling-decoupling transition. In addition, we find that in such multimode cavities, pronounced upper polariton emission is observed, in contrast to the usual case of a single-mode cavity. Furthermore, we address the ultrafast dynamics of the multimode cavities by pump-probe spectroscopic measurements and observe that the transient spectra significantly change through the transition.

Abstract
The common occurrence of antibiotic-resistance genes (ARGs) originating from pathogenic and facultative pathogenic bacteria pose a high risk to aquatic environments. Low removal of ARGs in conventional wastewater treatment processes and horizontal dissemination of resistance genes between environmental bacteria and human pathogens have made antibiotic resistance evolution a complex global health issue. The phenomenon of regrowth of bacteria after disinfection raised some concerns regarding the long-lasting safety of treated waters. Despite the inactivation of living antibiotic-resistant bacteria (ARB), the possibility of transferring intact and liberated DNA containing ARGs remains. A step in this direction would be to apply new types of disinfection methods addressing this issue in detail, such as light-based advanced oxidation, that potentially enhance the effect of direct light interaction with DNA. This study is devoted to comprehensively and critically review the current state-of-art for light-driven disinfection. The main focus of the article is to provide an insight into the different photochemical disinfection methods currently being studied worldwide with respect to ARGs removal as an alternative to conventional methods. The systematic comparison of UV/chlorination, UV/H2O2, sulfate radical based-AOPs, photocatalytic processes and photoFenton considering their mode of action on molecular level, operational parameters of the processes, and overall efficiency of removal of ARGs is presented. An in-depth discussion of different light-dependent inactivation pathways, influence of DBP and DOM on ARG removal and the potential bacterial regrowth after treatment is presented. Based on presented revision the risk of ARG transfer from reactivated bacteria has been evaluated, leading to a future direction for research addressing the challenges of light-based disinfection technologies.

Abstract
OBJECTIVE Biochemical joint changes contribute to posttraumatic osteoarthritis (PTOA) development following anterior cruciate ligament reconstruction (ACLR). The purpose of this longitudinal cohort study was to compare tibiofemoral cartilage composition between ACLR patients with different serum biochemical profiles. We hypothesized that profiles of increased inflammation (monocyte chemoattractant protein-1 [MCP-1]), type-II collagen turnover (type-II collagen breakdown [C2C]:synthesis [CPII]), matrix degradation (matrix metalloproteinase-3 [MMP-3] and cartilage oligomeric matrix protein [COMP]) preoperatively to 6-months post-ACLR would be associated with greater tibiofemoral cartilage T1ρ relaxation times 12-months post-ACLR. DESIGN Serum was collected from 24 patients (46% female, 22.1 ± 4.2 years old, 24.0 ± 2.6 kg/m2 body mass index [BMI]) preoperatively (6.4 ± 3.6 days post injury) and 6-months post-ACLR. T1ρ Magnetic Resonance Imaging (MRI) was collected for medial and lateral tibiofemoral articular cartilage at 12-months post-ACLR. A k-means cluster analysis was used to identify profiles based on biomarker changes over time and T1ρ relaxation times were compared between cluster groups controlling for sex, age, BMI, concomitant injury (either meniscal or chondral pathology), and Marx Score. RESULTS One cluster exhibited increases in MCP-1 and COMP while the other demonstrated decreases in MCP-1 and COMP preoperatively to 6-months post-ACLR. The cluster group with increases in MCP-1 and COMP demonstrated greater lateral tibial (adjusted mean difference = 3.88, 95% confidence intervals [1.97-5.78]) and femoral (adjusted mean difference = 12.71, 95% confidence intervals [0.41-23.81]) T1ρ relaxation times. CONCLUSION Profiles of increased serum levels of inflammation and matrix degradation markers preoperatively to 6-months post-ACLR are associated with MRI changes consistent with lesser lateral tibiofemoral cartilage proteoglycan density 12-months post-ACLR.

Abstract
INTRODUCTION Prevalence of obesity and associated diseases, including type 2 diabetes mellitus, dyslipidaemia and non-alcoholic fatty liver disease (NAFLD), are increasing. Underlying mechanisms, especially in humans, are unclear. Bariatric surgery provides the unique opportunity to obtain biopsies and portal vein blood-samples. METHODS The BARIA Study aims to assess how microbiota and their metabolites affect transcription in key tissues and clinical outcome in obese subjects and how baseline anthropometric and metabolic characteristics determine weight loss and glucose homeostasis after bariatric surgery. We phenotype patients undergoing bariatric surgery (predominantly laparoscopic Roux-en-Y gastric bypass), before weight loss, with biometrics, dietary and psychological questionnaires, mixed meal test (MMT) and collect fecal-samples and intra-operative biopsies from liver, adipose tissues and jejunum. We aim to include 1500 patients. A subset (approximately 25%) will undergo intra-operative portal vein blood-sampling. Fecal-samples are analyzed with shotgun metagenomics and targeted metabolomics, fasted and postprandial plasma-samples are subjected to metabolomics, and RNA is extracted from the tissues for RNAseq-analyses. Data will be integrated using state-of-the-art neuronal networks and metabolic modeling. Patient follow-up will be ten years. RESULTS Preoperative MMT of 170 patients were analysed and clear differences were observed in glucose homeostasis between individuals. Repeated MMT in 10 patients showed satisfactory intra-individual reproducibility, with differences in plasma glucose, insulin and triglycerides within 20% of the mean difference. CONCLUSION The BARIA study can add more understanding in how gut-microbiota affect metabolism, especially with regard to obesity, glucose metabolism and NAFLD. Identification of key factors may provide diagnostic and therapeutic leads to control the obesity-associated disease epidemic.

Abstract
OBJECTIVE To determine whether World Trade Center (WTC)-exposure intensity and post-traumatic stress disorder (PTSD) are associated with subjective cognitive change in rescue/recovery workers. METHOD The population included 7875 rescue/recovery workers who completed a subjective cognition measure, the Cognitive Function Instrument (CFI), between 3/1/2018 and 2/28/2019 during routine monitoring, indicating whether they had experienced cognitive and functional difficulties in the past year. Higher scores indicated greater self-perceived cognitive change. Probable PTSD, depression, and alcohol abuse were evaluated by validated mental health screeners. Logistic regression assessed the associations of WTC exposure and current PTSD with top-quartile (≥2) CFI score, and of early post-9/11 PTSD with top-quartile CFI in a subpopulation (N = 6440). Models included demographics, smoking, depression, and alcohol abuse as covariates. RESULTS Mean age at CFI completion was 56.7 ± 7.7 (range: 36-81). Participants with high-intensity WTC exposure had an increased likelihood of top-quartile CFI score (odds ratio[OR] vs. low exposure: 1.32, 95%CI: 1.07-1.64), controlling for covariates. Current and early PTSD were both associated with top-quartile CFI (OR: 3.25, 95%CI: 2.53-4.19 and OR: 1.56, 95%CI: 1.26-1.93) respectively. CONCLUSIONS High-intensity WTC exposure was associated with self-reported cognitive change 17 years later in rescue/recovery workers, as was PTSD. Highly WTC-exposed subgroups may benefit from additional cognitive evaluation and monitoring of cognition over time.

Abstract
BACKGROUND Few studies have evaluated the impact of Baby Friendly Hospital Initiative (BFHI) implementation on underserved populations in the United States. We undertook this study in New Mexico, a large southwestern state with a diverse population and limited health care access. METHODS A quasi-experimental, retrospective cohort design was used to compare short-term breastfeeding duration between a pre-BFHI and a post-BFHI cohort. Among the post-BFHI cohort, logistic regression models were fitted to predict short-term breastfeeding duration from both individual and cumulative exposure to inpatient maternity care practices (Steps 4 to 9). RESULTS Implementation of the BFHI and cumulative exposure to the Ten Steps increased short-term duration of any breastfeeding and exclusive breastfeeding at 2-6 weeks postpartum. Exposure to all six of the inpatient Ten Steps increased the odds of any breastfeeding by 34 times and exclusive breastfeeding by 24 times. Exposure to Step 9 ("Give no pacifiers or artificial nipples") uniquely increased the likelihood of any breastfeeding at 2-6 weeks postpartum by 5.7 times, whereas Step 6 ("Give infants no food or drink other than breastmilk") increased the rate of exclusive breastfeeding by 4.4 times at 2-6 weeks postpartum. CONCLUSION These findings demonstrate that the Baby Friendly Hospital Initiative can have a positive impact on breastfeeding among underserved populations.

Abstract
The high use of antibiotics in human and veterinary medicine has led to a wide spread of antibiotics and antimicrobial resistance into the environment. In recent years, various studies have shown that antibiotic residues, resistant bacteria and resistance genes, occur in aquatic environments and that clinical wastewater seems to be a hot spot for the environmental spread of antibiotic resistance. Here a representative statistical analysis of various sampling points is presented, containing different proportions of clinically influenced wastewater. The statistical analysis contains the calculation of the odds ratios for any combination of antibiotics with resistant bacteria or resistance genes, respectively. The results were screened for an increased probability of detecting resistant bacteria, or resistance genes, with the simultaneous presence of antibiotic residues. Positive associated sets were then compared, with regards to the detected median concentration, at the investigated sampling points. All results show that the sampling points with the highest proportion of clinical wastewater always form a distinct cluster concerning resistance. The results shown in this study lead to the assumption that ciprofloxacin is a good indicator of the presence of multidrug resistant P. aeruginosa and extended spectrum β-lactamase (ESBL)-producing Klebsiella spec., Enterobacter spec. and Citrobacter spec., as it positively relates with both parameters. Furthermore, a precise relationship between carbapenemase genes and meropenem, regarding the respective sampling sites, could be obtained. These results highlight the role of clinical wastewater for the dissemination and development of multidrug resistance.

Abstract
ObjectivesThe purpose of this study was to evaluate the functionality of potato starch (PS), rice starch (RS), and plum concentrate (PC) as a replacement for phosphates in clean label curing brines, determined by the industry significant attributes of smokehouse yields, sensory analysis, and color scores.Materials and MethodsFresh inside ham pieces (Semimembranosus + Adductor) (n = 80), USDA-IMPS # 402F, were denuded and split into halves. Inside ham pieces were randomly assigned to one of four treatments including: a control containing traditional curing ingredients (CON), and three treatments with natural curing alternatives containing either plum concentrate (PC), potato starch (PS), or rice starch (RS) as phosphate replacement. Clean label treatment hams (CLT) were evaluated in conjunction with a traditional processed ham control (CON). The control brine was made with the addition of phosphate; whereas, the three clean label treatment brines received phosphate replacement inclusion via the vacuum tumbler. The ham pieces from all treatments were injected to approximately 125% of their fresh weight using a multi- needle injector. Hams were vacuum tumbled with a target post tumble weight of 130%. Inclusion rates for treatments included 2.25% (PS, RS) and 1.1% (PC) of the projected final meat block weight. Hams were then tumbled for 2 h at –15 mm Hg and 12 RPM (industry standard). Hams were cooked to an internal temperature of 62.7°C without the addition of smoke and chilled in accordance with USDA-FSIS Appendix B. They were then vacuum packaged and held under refrigeration (4°C) for 21d. Hams were evaluated for smokehouse yields, sensory analysis, and color scores. Ham samples were evaluated for: initial and sustained juiciness, initial and sustained tenderness, off flavors, ham flavor intensity, and mouth feel. Ham slices were held vacuum packaged, under refrigeration for an additional 7d, and then evaluated for L*, a*, b* color space values at 28d post cooking to simulate a retail setting. Differences in treatment results were analyzed using the MIXED models procedure of SAS.ResultsHams treated with PS had the highest cooking and overall yield (P < 0.05), PC hams had the lowest cooking and overall yield (P < 0.05), and RS hams were comparable to CON. The CLT were darker and less red than CON (P < 0.05). Similarly, CON had the highest a* value (P < 0.05) indicating a significant redder color compared to PS, RS, and PC; additionally, CON had a higher b* (P < 0.05) compared to clean label treatments. The CON had decreased tenderness compared to CLT (P < 0.05). For all other sensory attributes CLT was comparable to CON. Trained sensory analysis determined all phosphate replacements maintained or improved sensory attributes over the control. Cooking yields were improved by PS, held similar by RS, and decreased significantly by PC when compared to the control. Both PS and RS should be considered acceptable phosphate replacements in natural curing brines.ConclusionBased on research presented, PS and RS are suitable replacement for phosphates in natural curing brines based on similar or improved yields, and similar or improved sensory attributes. Due to its extreme cooking loss PC is not a recommended phosphate replacement.

Abstract
ObjectivesThe objective of this study was to determine if an increased brine temperature could impact smokehouse yield, sensory characteristics, and color scores of bacon.Materials and MethodsFresh pork bellies (n = 30) were randomly assigned to one of three brine temperatures: –1°C (COLD), 10°C (MED), and 21°C (WARM). Bellies were injected using a multi-needle injector at 13% of the green weight containing a 1.5% salt inclusion level. All bellies were heat treated in a smokehouse to 50°C. Bellies were chilled for 24 h to an internal temperature of 4°C. After chilling, weights were measured to calculate smokehouse yield. Bellies were tempered to –4°C, sliced 4 mm in thickness, and vacuum packaged into 0.22 kg packages. Samples from each treatment were placed under UV lighting to mimic a retail setting. Trained sensory and color panels were conducted on d 1, 7, 14, 21, 28, and 35. Panelists evaluated sliced bacon packages for cured color intensity, cured color characterization, cured color fading, and off odor. Samples were cooked in a convection oven for 15 min at 177°C and were evaluated for saltiness, oxidized flavor, and flavor intensity. Data were analyzed using the MIXED models procedure of SAS. Least-squares means were computed for each dependent variable, and statistically separated by a pair-wise t-test with predetermined α = 0.05.ResultsGreen weight pump percentage, smokehouse weight percentage, and chilled weight percentage for all treatments were similar (P > 0.05). Trained sensory panel results revealed no significant differences (P > 0.05) for salt flavor between treatments on d 1, 28, and 35. The MED brine was more acceptable than the COLD and WARM brines for salt flavor on d 7 and 14 (P < 0.05). Oxidized flavor on d 1, 7, 14, 21, and 28 were similar for all treatments (P > 0.05), but by d 35 the COLD treatment had significantly less oxidized flavor than the MED and WARM treatments. No significant differences (P > 0.05) were found for flavor intensity between treatments for each day. No differences (P > 0.05) were found between treatments on d 1, 7, or 14 for cured color intensity and characterization. However, on d 21 and 35 the MED brine temperature had the most intense cured color (P < 0.05). On d 35, cured color characterization for the MED brine revealed a darker cured color (P < 0.05) compared to the COLD treatment but was similar to the WARM treatment. Cured color fading showed no differences (P > 0.05) between treatments on d 1, 7, 14, 21, and 28. On d 35 the COLD brine exhibited significantly (P < 0.05) higher levels of cured color fading compared to both the MED and WARM brines. No significant differences were found between treatments for all days for off odor (P > 0.05); however, d 35 was significantly higher than all other days within treatments (P < 0.05).ConclusionProcessing yields were not significantly affected by brine temperature. Salt flavor and flavor intensity were not affected by brine temperature. In conclusion, cured meat color and oxidized flavor can be affected by brine temperature.

Abstract
The World Health Organization (WHO) has identified the spread of antibiotic resistance as one of the major risks to global public health. An important transfer route into the aquatic environment is the urban water cycle. In this paper the occurrence and transport of antibiotic microbial resistance in the urban water cycle are critically reviewed. The presence of antibiotic resistance in low impacted surface water is being discussed to determine background antibiotic resistance levels, which might serve as a reference for treatment targets in the absence of health-based threshold levels. Different biological, physical and disinfection/oxidation processes employed in wastewater treatment and their efficacy regarding their removal of antibiotic resistant bacteria and antibiotic resistance geness (ARGs) were evaluated. A more efficient removal of antibiotic microbial resistance abundances from wastewater effluents can be achieved by advanced treatment processes, including membrane filtration, ozonation, UV-irradiation or chlorination, to levels typically observed in urban surface water or low impacted surface water.

Abstract
Biofilm-forming bacteria are ubiquitous in the environment and also include biofilm-forming pathogens. Environmental biofilms may form a reservoir for risk genes and may act as a challenge for human health. Examples of the health relevance of biofilms are the increase in antibiotic resistant bacteria hosted in biofilms in hospital and environment and consequently the interaction of these bacteria with human cells, e.g. in the immune system. Although data concerning the occurrence and spread of resistant bacteria within hospital care units are available, the fate of these bacteria in the environment and especially in the aquatic environment has barely been investigated. Once antibiotic resistant bacteria have entered the environment, a back coupling by ingestion or other possible entry into the host has to be prevented. Therefore a strategy to investigate paths of entry, accumulation and spread of resistant bacteria in environmental compartments has been developed using quantitative determination of genetic resistance determinants. Additionally a bacterial bioassay assessed bioeffectivity thresholds of low antibiotic concentrations. This approach enables an evaluation of the potential of contaminated waters to exert a selection pressure on bacterial communities and thus promote the persistence of resistant organisms. Completed with an indicator system for the identification of sources of multiresistant bacteria a concept for monitoring and evaluation of environmental compartments with respect to their potential of antibiotic resistance dissemination is suggested.

Abstract
An increasing proportion of humanity lives in urban environments where they spend most of their lives indoors. Recent molecular studies have shown that bacterial assemblages in built environments (BEs) are extremely diverse, but BE fungal diversity remains poorly understood. We applied culture-independent methods based on next-generation sequencing (NGS) of the fungal internal transcribed spacer to investigate the diversity and temporal dynamics of fungi in restrooms. Swab samples were collected weekly from three different surfaces in two public restrooms (male and female) in San Diego, CA, USA, over an 8-week period. DNA amplification and culturing methods both found that the floor samples had significantly higher fungal loads than other surfaces. NGS sequencing of floor fungal assemblages identified a total of 2550 unique phylotypes (~800 per sample), less than half of which were identifiable. Of the known fungi, the majority came from environmental sources and we found little evidence of known human skin fungi. Fungal assemblages reformed rapidly in a highly consistent manner, and the variance in the species diversity among samples was low. Overall, our study contributes to a better understanding of public restroom floor fungal communities.

Abstract
OBJECTIVE Pre-implantation genetic diagnosis (PGD) is required in order to screen and diagnose embryos of patients at risk of having a genetically affected offspring. A biopsy to diagnose the genetic profile of the embryo may be performed either before or after cryopreservation. The aim of this study was to determine which biopsy timing yields higher embryo survival rates. STUDY DESIGN Retrospective cohort study of all PGD patients in a public IVF unit between 2010 and 2013. Inclusion criteria were patients with good-quality embryos available for cryopreservation by the slow freezing method. Embryos were divided into two groups: biopsy before and biopsy after cryopreservation. The primary outcome was embryo survival rates post thawing. RESULTS Sixty-five patients met inclusion criteria. 145 embryos were biopsied before cryopreservation and 228 embryos were cryopreserved and biopsied after thawing. Embryo survival was significantly greater in the latter group (77% vs. 68%, p < 0.0001). CONCLUSION Cryopreservation preceding biopsy results in better embryo survival compared to biopsy before cryopreservation.

Abstract
The objectives of the present work are to evaluate long-term benefit of nonexcitatory gastric electrical stimulation (GES) by the DIAMOND(®) device on glycemic control and body weight in patients with type 2 diabetes inadequately controlled with oral agents and to determine the magnitude of the modulating effects of fasting plasma triglyceride (FTG) levels on these effects of GES. Sixty one patients with type 2 diabetes [HbA1c > 7.0% (53 mmol/mol) to < 10.5% (91 mmol/mol)] were implanted with the DIAMOND(®) GES device and treated with meal-mediated antral electrical stimulation for up to 36 months. The effects of baseline HbA1c and FTG on glycemic control, body weight, and systolic blood pressure were measured. GES reduced mean HbA1c by 0.9% and body weight by 5.7%. The effects were greater in patients with normal fasting plasma triglycerides (NTG) as compared to those with hypertriglyceridemia. The mean decrease in HbA1c in patients with NTG averaged 1.1% and was durable over 3 years of follow-up. ANCOVA indicated that improvement in HbA1c was a function of both baseline FTG group (p = 0.02) and HbA1c (p = 0.001) and their interaction (p = 0.01). Marked weight loss (≥ 10%) was observed in a significant proportion of NTG patients by 12 months of treatment and persisted through the 3 years. GES improves glycemic control and reduces body weight by a triglyceride-dependent mechanism in patients with type 2 diabetes inadequately controlled on oral agents. It is postulated that this is through a gut-brain interaction that modulates effects on the liver and pancreatic islets.

Abstract
Antibiotics are emerging contaminants, which wing to their bioactivity, may lead to short-term and long-term alterations of natural microbial communities in aquatic environment. We investigated the effects of antibiotics on biofilm bacterial communities in the Llobregat River (Northeast Spain). Three sampling sites were selected: two less polluted sites and one hotspot. River water was collected from each site and used both as inoculum and medium for growing biofilms in independent mesocosms. After 25d of biofilm colonization, we exposed the colonized biofilms to river waters from the downstream sites (progressively contaminated by antibiotics). A control from each site was maintained where the growing biofilm was always exposed to water from the same site. The bacterial community composition, bacterial live/dead ratio and extracellular enzyme activities of the biofilms were measured before and 9d after exposing the biofilms to increasing contaminated waters. Sixteen antibiotic compounds were detected in the water from the three sampling sites. At each site, the antibiotics present in the highest concentrations were sulfonamides, followed by quinolones and macrolides. Bacterial communities of biofilms grown with the three river waters differed markedly in their structure, but less so in terms of functional descriptors. After switching the medium water to increasing pollution, biofilms exhibited increased levels of actinobacteria (HGC), a trend that was associated to the higher antibiotic concentrations in the water. These biofilms also showed increased bacterial mortality, and decreased extracellular leucine-aminopeptidase and alkaline phosphatase. There was a significant correlation between antibiotic concentrations and biofilm responses. Our results indicate that the continuous entrance of antibiotics in running waters cause significant structural and functional changes in microbial attached communities.

Abstract
BACKGROUND Non-stimulatory, meal-mediated electrical stimulation of the stomach (TANTALUS-DIAMOND) improves glycaemic control and causes modest weight loss in patients with Type 2 diabetes who are inadequately controlled on oral anti-diabetic medications. The magnitude of the glycaemic response in clinical studies has been variable. A preliminary analysis of data from patients who had completed 6 months of treatment indicated that the glycaemic response to the electrical stimulation was inversely related to the baseline fasting plasma triglyceride level. METHOD An analysis of 40 patients who had had detailed longitudinal studies for 12 months. RESULTS Twenty-two patients with fasting plasma triglycerides ≤ 1.7 mmol/l had mean decreases in HbA1c after 3, 6 and 12 months of gastric contraction modulation treatment of -15 ± 2.1 mmol/mol (-1.39 ± 0.20%), -16 ± 2.2 mmol/mol (-1.48 ± 0.20%) and -14 ± 3.0 mmol/mol (-1.31 ± 0.26%), respectively. In contrast, 18 patients with fasting plasma triglyceride > 1.7 mmol/l had mean decreases in HbA1c of -7 ± 1.7 mmol/mol (-0.66 ± 0.16%), -5 ± 1.6 mmol/mol (-0.44 ± 0.18%) and -5 ± 1.7 mmol/mol (-0.42 ± 0.16%), respectively. Pearson's correlation coefficient between fasting plasma triglyceride and decreases in HbA1c at 12 months of treatment was 0.34 (P < 0.05). Homeostasis model assessment of insulin resistance was unchanged during 12 months of treatment in patients with high baseline fasting triglycerides, while it progressively improved in patients with low fasting plasma triglycerides. Patients with low fasting plasma triglycerides had a tendency to lose more weight than those with high fasting plasma triglycerides, but this did not achieve statistical significance. CONCLUSIONS The data presented suggest the existence of a triglyceride lipotoxic mechanism that interferes with gastric/neural mediated pathways that can regulate glycaemic control in patients with type 2 diabetes. The data suggest the existence of a triglyceride lipotoxic pathway that interferes with gastric/neural mediated pathways that can regulate glycaemic control.

Abstract
Urban wastewater treatment plants (UWTPs) are among the main sources of antibiotics' release into various compartments of the environment worldwide. The aim of the present paper is to critically review the fate and removal of various antibiotics in wastewater treatment, focusing on different processes (i.e. biological processes, advanced treatment technologies and disinfection) in view of the current concerns related to the induction of toxic effects in aquatic and terrestrial organisms, and the occurrence of antibiotics that may promote the selection of antibiotic resistance genes and bacteria, as reported in the literature. Where available, estimations of the removal of antibiotics are provided along with the main treatment steps. The removal efficiency during wastewater treatment processes varies and is mainly dependent on a combination of antibiotics' physicochemical properties and the operating conditions of the treatment systems. As a result, the application of alternative techniques including membrane processes, activated carbon adsorption, advanced oxidation processes (AOPs), and combinations of them, which may lead to higher removals, may be necessary before the final disposal of the effluents or their reuse for irrigation or groundwater recharge.

Abstract
Urban wastewater treatment plants (UWTPs) are among the main sources of antibiotics' release into the environment. The occurrence of antibiotics may promote the selection of antibiotic resistance genes (ARGs) and antibiotic resistant bacteria (ARB), which shade health risks to humans and animals. In this paper the fate of ARB and ARGs in UWTPs, focusing on different processes/technologies (i.e., biological processes, advanced treatment technologies and disinfection), was critically reviewed. The mechanisms by which biological processes influence the development/selection of ARB and ARGs transfer are still poorly understood. Advanced treatment technologies and disinfection process are regarded as a major tool to control the spread of ARB into the environment. In spite of intense efforts made over the last years to bring solutions to control antibiotic resistance spread in the environment, there are still important gaps to fill in. In particular, it is important to: (i) improve risk assessment studies in order to allow accurate estimates about the maximal abundance of ARB in UWTPs effluents that would not pose risks for human and environmental health; (ii) understand the factors and mechanisms that drive antibiotic resistance maintenance and selection in wastewater habitats. The final objective is to implement wastewater treatment technologies capable of assuring the production of UWTPs effluents with an acceptable level of ARB.

Abstract
We demonstrate that photochromic molecules enable switching from the weak- to ultrastrong-coupling regime reversibly, by using all-optical control. This switch is achieved by photochemically inducing conformational changes in the molecule. Remarkably, a Rabi splitting of 700 meV is measured at room temperature, corresponding to 32% of the molecular transition energy. A similar coupling strength is demonstrated in a plasmonic structure. Such systems present a unique combination of coupling strength and functional capacities.

Abstract
AIMS The aim of this study is to investigate the safety and effectiveness of Excimer laser-assisted lead extraction in Europe. The final European multi-centre study experience is presented. METHOD AND RESULTS The Excimer is a cool cutting laser (50 degrees C) with a wavelength of 308 nm. The energy is emitted from the tip of a flexible sheath and is absorbed by proteins and lipids, 64% of the energy is absorbed at a tissue depth of 0.06 mm. The sheath is positioned over the lead, and the fibrosis surrounding the lead is vaporized while advancing the sheath without damaging other leads. From August 1996 to March 2001, 383 leads (170 atrial, 213 ventricular) in 292 patients (mean age 61.6 years, range 13-96) were extracted at 14 European centres. Mean implantation time was 74 months (3-358). Most frequent indications were pocket infection (26%), non-functional leads (21%), patient morbidity (21%), septicaemia or endocarditis (14%), erosion (5%), and lead interference (8%). Median extraction time was 15 min (1-300). Complete extraction was achieved in 90.9% of the leads and partial extraction in 3.4%. Extraction failed in 5.7% of the leads. Major complications = perforations caused 10/22 (3.4/5.7%) of the failures. Most partially extracted patients were considered clinically successful, as only minor lead parts without clinical significance were left. Femoral non-laser technique was used to remove 8/12 of the non-complication failures. The total complication rate, including five minor complications (1.7%), was 5.1%. No in-hospital mortality occurred. CONCLUSION Pacing and implantable cardioverter-defibrillator leads can safely, effectively, and predictably be extracted. Open-heart extractions can be limited to special cases. The results indicate that the traditional policy of abandoning redundant leads, instead of removing them, may be obsolete in many patients.

Abstract
PURPOSE Determination of skeletal development in children is important. The most used evaluation method is to study left hand X-ray based on the standards depicted by Greulich and Pyle. The aim of our study was to compare the accuracy of a new sonographically based method with the standard method. MATERIAL AND METHODS 160 consecutive evaluated children and adolescents (77 male, 83 female) who received a X-ray of the left hand were evaluated. Ultrasound examination of the same hand was performed on the same day using the BonAge system (Sunlight Medical Ltd., Israel). This system evaluates the relationship between the velocity of the wave (speed of sound) passing thorough the distal radial and ulna epiphysis and growth, using gender- and ethnicity-based algorithms. Three experienced investigators (U1-U3) analysed the X-ray and assigned bone age scores based on the Greulich and Pyle atlas (G and P). The investigators were blinded to the calendary age (CA) of the patient and also for the BonAge result. Correlation between BonAge system results and G and P was performed using SPSS 12.0.1. RESULTS In 152 patients BonAge measurement could be performed successfully. The correlation between the three investigators using the G and P method was between 0.977 and 0.980; correlation between the BonAge system and the investigators (U1-U3) was 0.902 and 0.920. The paired t-test showed no significant differences between the BonAge system and the three investigators and also for the comparison between U1 and U2. There were significant differences between U1 vs. U3 and U2 vs. U3 (p < 0.05). DISCUSSION The BonAge device demonstrates the ability to produce an sufficient assessment of bone age using an ultrasound method. The results are correlated with conventional skeletal age evaluation using the G and P method. Advantages of the ultrasound device are objectivity, lack of ionizing radiation, and easy accessibility. In the case of first investigation X-ray is necessary to look for dissociated skeletal age, dysplasia, and mineralisation.
