Plastics have become strong environmental stressors of coastal marine ecosystems. Their introduction into the marine ecosystem is subjected to different mechanisms, including the inadequate disposal of solid waste and dumping of wastewater. In addition, their chemical composition makes them resistant to variables such as temperature and salinity of water. These polymers are degraded and fragmented mainly due to the action of the waves, which results in the formation of smaller particles called microplastics. Microplastics are characterized by being persistent in the environment due to their low biodegradation, and although they have a maximum size of 5 mm, there is a wide range of sizes suggested by different authors. According to their use, microplastics can be classified as primary when they are recognized at first sight, and as secondary, when they are gradually divided. Microplastics have become a potential risk to the health of marine species due to their small size, and the risk to human health due to to frequent tourist places such as beaches.

This analysis evaluated the relationship between treatment-free interval (TFI, in PALOMA-2)/disease-free interval (DFI, in PALOMA-3) and progression-free survival (PFS) and overall survival (OS, in PALOMA-3), treatment effect in patients with bone-only disease, and whether intrinsic subtype affects PFS in patients receiving palbociclib.

Data were from phase 3, randomized PALOMA-2 and PALOMA-3 clinical studies of hormone receptor‒positive/human epidermal growth factor receptor 2‒negative (HR+ /HER2-) advanced breast cancer (ABC) patients receiving endocrine therapy plus palbociclib or placebo. #link# Subpopulation treatment effect pattern plot (STEPP) analysis evaluated the association between DFI and PFS and OS. PFS by luminal subtype and cyclin-dependent kinase (CDK) 4/6 or endocrine pathway gene expression levels were evaluated in patients with bone-only disease; median PFS and OS were estimated by the Kaplan-Meier method.

Median durations of TFI were 37.1 and 30.9months (PALOMA-2) and DFI were 49.2 and 52.0 or intrinsic molecular subtype, including patients with bone-only disease.

Most pediatric palliative care (PPC) services are inpatient consultation services and do not reach patients and families in the outpatient and home settings, where a vast majority of oncology care occurs. We explored whether an embedded pediatric palliative oncology (PPO) clinic is associated with receipt and timing of PPC and hospital days in the last 90days of life.

Oncology patients (ages 0-25) with a high-risk event (death, relapse/progression, and/or phase I/II clinical trial enrollment) between 07/01/2015 and 06/30/2018 were included. PPO clinic started July 2017. Two cohorts were defined pre-PPO (high-risk event(s) occurring 07/01/2015-06/30/2017) and post-PPO (high-risk event(s) occurring 07/01/2017-06/30/2018). Descriptive statistics were performed; demographic, disease course, and outcomes variables across cohorts were compared.

A total of 426 patients were included (pre-PPO n = 235; post-PPO n = 191). Forty-seven patients with events in both pre- and post-PPO cohorts were included in the post-PPO cohort. Mean age at diagnosis was 8years. Diagnoses were evenly distributed among solid tumors, brain tumors, and leukemia/lymphoma. Post-PPO cohort patients received PPC more often (45.6% vs. 21.3%, p < 0.0001), for a longer time before death than the pre-PPO cohort (median 88 vs. 32days, p = 0.027), and spent fewer days hospitalized in the last 90days of life (median 3 vs. 8days, p = 0.0084).

A limited-day, embedded PPO clinic was associated with receipt of PPC and spending more time at home in patients with cancer who had high-risk events. Continued improvements to these outcomes would be expected with additional oncology provider education and PPO personnel.

We outline five reasons that patients with advanced cancer would benefit from comprehensive assessments that include questions about cognitive complaints. Advanced cancer has all the characteristics that would lead to cognitive changes. Patients with advanced cancer may have a higher risk for cognitive impairment due to aggressive chemotherapies, higher symptom burden, and greater psychosocial distress. This commentary contextualizes how cognitive complaints may relate to multiple factors relevant to the advanced cancer patient. By simply asking the patient about their perceived cognitive changes, we argue this may be a stepping stone to finding non-pharmacological ways to address cognitive impairment.Plants in their natural environment are often exposed to fluctuating light because of self-shading and cloud movements. As changing frequency is a key characteristic of fluctuating light, we speculated that rapid light fluctuation may induce rapid photosynthetic responses, which may protect leaves against photoinhibition. To test this hypothesis, maize seedlings were grown under fluctuating light with various frequencies (1, 10, and 100 cycles of fluctuations/10 h), and changes in growth, chlorophyll content, gas exchange, chlorophyll a fluorescence, and P700 were analyzed carefully. Our data show that though the growth and light-saturated photosynthetic rate were depressed by rapidly fluctuating light, photosynthesis induction was clearly speeded up. Furthermore, more rapid fluctuation of light strikingly reduced the chlorophyll content, while thermal dissipation was triggered and enhanced. The chlorophyll a fluorescence induction kinetics and P700 absorption results showed that the activities of both photosystem II and photosystem I decreased as the frequency of the fluctuating light increased. In all treatments, the light intensities of the fluctuating light were kept constant. Therefore, rapid light fluctuation frequency itself induced the acceleration of photosynthetic induction and the enhancement of photoprotection in maize seedlings, which play important roles in protecting photosynthetic apparatus against fluctuating high light to a certain extent.Sepsis is a major cause of acute kidney injury (AKI) among patients in the intensive care unit. However, the numbers of basic science papers for septic AKI account for only 1% of all publications on AKI. This may be partially attributable to the specific pathophysiology of septic AKI as compared to that of the other types of AKI because it shows only modest histological changes despite functional decline and often requires real-time functional analysis. To increase the scope of research in this field, this article reviews the basic research information that has been reported thus far on the subject of septic AKI, mainly from the viewpoint of functional dysregulation, including some knowledge acquired with multiphoton intravital imaging. Moreover, the efficacy and limitation of the potential novel therapies are discussed. Finally, the author proposes several points that should be considered when designing the study, such as monitoring the long-term effects of the intervention and reflecting the clinical settings for identifying the molecular mechanisms and for challenging the intervention effects.

Peritonitis is one of the major complications of peritoneal dialysis (PD). Although several reports have indicated seasonality of peritonitis, the observation periods were short, and there were no reports from Japan. Therefore, the purpose of this study was to investigate the long-term seasonality of peritonitis in a single institution in Japan.

Of 126 patients who started PD in our hospital between January 1, 2009, and December 31, 2018, 25 patients (15 men, 10 patients with diabetes) developed peritonitis with a total of 42 episodes. The median age at onset was 63years, and the median duration from the start of PD to the onset of peritonitis was 22months.

The 10-year incidence of peritonitis was 0.12 episodes per patient-year. Compared with the reference season of winter (December-February), the incidence rate ratios (95% confidence interval) for spring (March-May), summer (June-August), and autumn (September-November) were 1.75 (0.65-4.75), 1.56 (0.57-4.31), and 2.42 (0.94-6.23), respectively. In addition, no seasonality of Gram-positive and Gram-negative organisms was observed.

No seasonality was evident in the incidence of PD-related peritonitis in our hospital over a 10-year period. These findings suggest that the development of peritonitis in Japanese PD patients is not affected by seasonality.

A total of 113 VRE isolates, 89 E. faecium (VREfm) and 24 E. link2 faecalis (VREfs), were collected in the study period. All strains showed high-level resistance to vancomycin; 107 also showed teicoplanin resistance. Altogether, 84 VREfm and 20 VREfs carried vanA, whereas 5 VREfm and 1 VREfs carried vanB. MLST analysis documented that 89 VREfm isolates mainly belonged to ST78, ST80, and ST117. Most strains were isolated from 2001 to 2007, ST78 being the predominant clone. VREfm re-emerged in 2016 with a prevalence of the ST80 lineage. link3 Most VREfs were isolated from 2001 to 2006; although they belonged to 7 different STs, there was a prevalence of ST88 and ST6. Notably, ST88 was sporadically recovered throughout the study period. The increasing rate of VREfm isolation from 2016 to 2018 may be related to the influx of new successful clones and to the renewed and widespread use of vancomycin. Improved infection control measures in hospital wards should be adopted to limit the spread of new epidemic VRE strains.The world is witnessing a serious public health threat in the wake of the third corona virus pandemic, a novel corona virus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]). The Corona Virus Disease-19 (COVID-19) is not limited to the respiratory system but has widespread involvement including the gastrointestinal (GI) tract and liver, with evidence of prolonged fecal shedding and feco-oral transmission. This finding has stirred up a hornet's nest of not only a newer modality of the spread of the virus but also a risk of the unpredictable duration of the infective potential of the shedders. ARV-771 reviewed the literature on fecal shedding and possible implications on prevention and surveillance strategies. The pandemic is changing the management of underlying chronic diseases such as inflammatory bowel disease (IBD) and other diseases. Moreover, for the gastroenterologist, doing endoscopic procedures in this COVID-19 era poses a high risk of contamination, as it is an aerosol-generating procedure. There is a daily influx of data on this disease, and multiple societies are coming up with various recommendations.
