0446). There was no significant difference between the median baseline values of PLR and NLR; and age ≥75, positive regional lymph node metastases (N+), and chemotherapy after RT were significantly associated with poor OS. Multivariate analysis revealed a significant association of N+ with worse OS, PFS, and CSS and that lower LCR was significantly associated with better PFS (p=0.0234). Among late toxicity events, two patients (3.38%) were suspected with therapy-related liver toxicity.

Lower LCR before RT was a better prognostic factor for postoperative RT of patients with CCA.

Many hospitals have been using nutrition support guidelines for patients with coronavirus disease 2019 (COVID-19) as outlined in the April 2020 article released by the American Society for Parenteral and Enteral Nutrition (ASPEN) and the Society of Critical Care Medicine (SCCM). Currently, there are insufficient data on the outcomes of following these guidelines.

This was a retrospective, observational study of 131 adult inpatients with COVID-19 admitted to an intensive care unit (ICU) at Banner Health to observe differences in length of stay, mortality, and number of days intubated based on the timing of nutrition support start relative to hours intubated and hours in the ICU.

There were no statistically significant differences between length of stay, mortality, or number of days intubated between patients who started nutrition support within <12 h of intubation, >12 h of intubation and <36 h in the ICU, or >36 h of intubation and those who were not intubated. Patients who started nutrition support after >36 h in the ICU had the longest lengths of stay (median [25th, 75th percentile]  = 25.5 [19.25, 35.25] days; P > 0.05) and number of days intubated (16.5 [10.0, 24.75] days; P > 0.050); however, it was not statistically significant. There was a significant difference between the three intubated groups and the nonintubated group on Sequential Organ Failure Assessment scores (P = 0.01).

Prospective, multicenter trials are needed; however, following the SCCM/ASPEN guidelines for nutrition support in patients with COVID-19 may be found to decrease length of stay and number of days intubated.

During the pandemic, the frontline healthcare workers experience intense anxiety, stress, burnout, and psychological breakdown, with severe implications on their mental and physical well-being. In addition to these implications, anxiety and stress can hinder their productivity and ability to perform their duties efficiently. The literature indicates that hospital gardens and contact with nature can help alleviate psychological distress among hospital staff. However, few studies investigated the role of outdoor spaces as areas for respite and work breaks in healthcare facilities during the pandemic. The present opinion paper highlights the challenges of job stress and psychological distress health workers face during the pandemic. This article also underscores the role of hospital outdoor spaces and garden facilities in coping with the challenges. While other measures to reduce stress among hospital staff and ensure their health and safety are important, hospital administrators and relevant government agencies should also emphasize the provision of gardens and open spaces in healthcare facilities. These spaces can act as potential areas for respite for hospital staff to help them cope with the stress and anxiety accumulated through working under crises.
During the COVID-19 pandemic, the Centers for Disease Control and Prevention (CDC) and ASHRAE provided infection control recommendations for the built environments and ventilation systems of nursing homes (NHs). The level of adoption of the suggested strategies is unknown, as little information has been obtained from NHs identifying the strategies that were implemented.

The primary goal of our study was to characterize the built environments of Colorado NHs during the COVID-19 pandemic to assess the level of adoption of CDC and ASHRAE recommendations. Our secondary goal was to identify opportunities and barriers that NHs face as they work to create health-protective built environments in the future.

We used the Nursing Home Built Environment survey to obtain data related to three main categories of CDC and ASHRAE recommendation for Colorado NHs Resident Isolation, Improved Indoor Air Quality, and Staff Separation/Support.

Key findings included (1) On average, NHs had 34% of their beds located in single-occupancy rooms; (2) seven (9%) NHs had designated COVID-positive "neighborhoods"; (3) 14 (20%) NHs had common area ventilation systems that were utilizing filters with a minimum efficiency reporting value 13 rating, or higher.

Most Colorado NHs did not fully implement the COVID-19 built environment strategies recommended by CDC and ASHRAE. While there are barriers to the adoption of many of the strategies, there are also opportunities for immediate improvements that can support the health of vulnerable NH populations as we continue to see high rates of aerosolized infectious disease spread in NH facilities.

N-duration and A1-P0 (degree of V-nasalization) are measured in consonant-vowel-nasal (CVN) and nasal-vowel-consonant (NVC) words in various prosodic structural conditions (phrase-final vs. phrase-medial; focused vs. unfocused). Korean learners show a systematic fine-tuning of the non-contrastive V-nasalization in second language (L2) English in relation to prosodic structure, although it does not pertain to learning new L2 sound categories (i.e., L2 English nasal consonants are directly mapped onto Korean nasal consonants). The prosodic structurally conditioned phonetic detail in English appears to be accessible in most part to Korean learners and was therefore reflected in their production of L2 English. Their L2 production, however, is also found to be constrained by their first language (L1-Korean) to some extent, resulting in some phonetic effects that deviate from both L1 and L2. The results suggest that the seemingly low-level coarticulatory process is indeed under the speaker's control in L2, which reflects interactions of the specificities of the phonetics-prosody interface in L1 and L2. The results are also discussed in terms of their implications for theories of L2 phonetics.In this study, 32 male Sprague-Dawley rats (8 for each group) were used in total to examine the effects of valproic acid on rat cerebellum. It was determined that the experimental group received valproic acid (600 mg/kg) on embryonic day 15 and postnatal day 11, whereas the control group was treated with saline on the same days. Moreover, on the postnatal 30th day, the cerebellums of all pups were removed and prepared for light and electron microscopy. The numerical density of granule cells in the cerebellum of experimental groups of rats increased, whereas the numerical density of Purkinje cells decreased. Furthermore, the granule cells had a smaller mean nuclear diameter in one of the experimental groups, while the Purkinje cells had in both experimental groups than those in the comparison group. Thus, the numerical density of synaptic disks and their mean diameter in the cerebellar granular layer of experimental groups were significantly decreased compared to the corresponding controls; also, the synapse-to-neurons ratio, a parameter indicating interneural connectivity, was the same. Consequently, it was seen that valproic acid administration to pups in prenatal or early postnatal days causes changes in number of neurons and synapses in the cerebellum of rats.
Type 2 diabetes mellitus (T2DM) is the ninth leading cause of mortality globally, and the prevalence continues to rise. Among individuals with T2DM, over two-thirds of deaths are caused by the cardiovascular complications of diabetes. These complications include atherosclerosis, coronary artery disease, nephropathy, stroke, thromboembolism, peripheral vascular disease. They have been long studied, and there are several theories as to the pathophysiology of how diabetes leads to these complications. The least understood mechanism is the pathophysiology linking diabetes to heart failure.

This review focuses on the mechanisms of how T2DM leads to the aforementioned complications, particularly highlighting the development of heart failure. An extensive literature review of novel therapeutic options targeting the cardiovascular effects of T2DM was completed and summarized in this review.

This review finds that most studies to date have focused on the atherosclerotic vascular complications of diabetes. The pathophysiology between T2DM and heart failure is even less understood. Currently therapies that aim to decrease the risk of heart failure in diabetes are sparse. More research is required in order to better understand the changes at a cellular level and subsequently help providers to choose therapeutics that better target cardiovascular complications.

These antibodies can activate neutrophils and the complement system resulting in vessel wall inflammation and damage. The clinical presentation of AAV varies from non-severe (non-life threatening) to severe often with potentially life-threatening multi-organ involvement. Early recognition and diagnosis are crucial. In the past two decades, advances in understanding the pathophysiology of AAV have led to development of new treatments and resulted in significant improvement in general outcomes and survival rates.
