RESUMO
Background: Development of computer-based software, termed electronic glucose management system (eGMS), offers an alternative strategy to manage diabetic ketoacidosis (DKA) compared with institution-specific paper protocols by integrating glucose and insulin titration into the electronic medical record. Objective: To evaluate the safety and efficacy of eGMS versus a paper-based DKA protocol in an urban academic medical center. Methods: Single-center, retrospective analysis of patients admitted for DKA. The primary objective of this study was the time to transition from intravenous to subcutaneous insulin after resolution of DKA pre- and post-eGMS implementation. Secondary outcomes included incidence of hypoglycemia while on an insulin infusion, intensive care unit (ICU) length of stay, and total hospital length of stay. Results: Time to DKA resolution was similar in both groups with a median time of 8.6 versus 8.8 hours in the paper-based (n = 133) and eGMS groups (n = 84), respectively (P = 0.43). Hypoglycemia occurred more frequently in the paper-based group compared with eGMS during insulin infusion (14 vs 3 patients, P = 0.06). The median ICU (36.5 vs 41.4 hours; P = 0.05) and hospital length of stay (67.9 vs 77.8 hours; P = 0.05) were shorter in the paper-based group compared with the eGMS group. Conclusion and Relevance: Similar rates of DKA resolution were seen for patients managed with a paper-based protocol compared with eGMS. Patients in the paper-based protocol had a shorter ICU and hospital length of stay; however, eGMS had improved clinically relevant safety outcomes.
RESUMO
Exposure to air pollution, including criteria pollutants such as fine particulate matter (PM2.5) and ozone (O3), has been associated with morbidity and mortality in mammals. As a genetically homogenous population that is closely monitored for health, dairy cattle present a unique opportunity to assess the association between changes in air pollution and mammalian health. Milk yield decreases in the summer if temperature and humidity, measured by the Temperature Humidity Index (THI). As O3 levels increase with warmer temperatures, and summer PM2.5 may increase with wildfire smoke, dairy cows may serve as a useful sentinel species to evaluate subacute markers of inflammation and metabolic output and ambient pollution. Over two years, we assessed summertime O3 and PM2.5 concentrations from local US EPA air quality monitors into an auto-regressive mixed model of the association between THI and daily milk production data and bulk tank somatic cell count (SCC). In unadjusted models, a 10 unit increase THI was associated with 28,700 cells/mL (95% CI: 17,700, 39,690) increase in SCC. After controlling for ambient air pollutants, THI was associated with a 14,500 SCC increase (95% CI: 3,400, 25,680), a 48% decrease in effect compared to the crude model. Further, in fully adjusted models, PM2.5 was associated with a 105,500 cells/mL (95% CI: 90,030, 121,050) increase in SCC. Similar results were found for milk production. Results were amplified when high PM2.5 days (95th percentile of observed values) associated with wildfire smoke were removed from the analyses. Our results support the hypothesis that PM2.5 confounds the relationships between THI and milk yield and somatic cell count. The results of this study can be used to inform strategies for intervention to mitigate these impacts at the dairy level and potentially contribute to a model where production animals can act as air quality sentinels.

This article describes how an acute care organization in Texas, a peer review mandated state, created a nonpunitive peer feedback structure and process for nursing staff. Strategies were targeted to improve patient outcomes. A peer feedback committee designed, implemented, and evaluated the feedback model to coexist with the state-required formal peer review committee structure. Peer feedback provided opportunities to advance skill development, enhance quality improvement, improve patient outcomes, and support a culture of safety within the healthcare environment.

In 2020-2021, a Colorado corrections facility experienced four COVID-19 outbreaks. Case counts, attack rates (ARs) in people who are detained or incarcerated (PDI), and mitigation measures used in each outbreak were compared to evaluate effects of combined strategies. Serial PCR testing, isolation/quarantine, and masking were implemented in outbreak 1. Daily staff antigen testing began in outbreak 2. Facility-wide COVID-19 vaccination started in outbreak 3 and coverage increased by the end of outbreak 4 (PDI: <1% to 59%, staff: 27% to 40%). Despite detection of variants of concern, outbreaks 3 and 4 had 97% lower PDI ARs (both 1%) than outbreak 2 (29%). Daily staff testing and increasing vaccination coverage, with other outbreak mitigation strategies, are important to reduce COVID-19 transmission in congregate settings.

Eight people with human body louse-borne Bartonella quintana infections were detected among people experiencing homelessness (PEH) in Denver during January-September 2020, prompting a public health investigation and community outreach. Public health officials conducted in-person interviews with PEH to more fully quantify body lice prevalence, transmission risk factors, access to PEH resources, and how the COVID-19 pandemic has affected resource access. Recent body lice exposure was reported by 35% of 153 interview participants. In total, 75% of participants reported reduced access to PEH services, including essential hygiene activities to prevent body lice, during Colorado's COVID-19 stay-at-home orders. Future pandemic planning should consider hygiene resource allocation for PEH populations to prevent emerging and reemerging infections such as B. quintana.

Physical inactivity remains a global epidemic leading to an estimated 5 million preventable deaths per year. Although there exist numerous public-health campaigns aimed at increasing physical activity (PA), a potentially fruitful but underexplored avenue to promote both human and animal health is veterinary-prescribed PA programs. The aim of this study was to determine the feasibility and acceptability of incorporating veterinary-prescribed PA programming into a diverse array of clinic settings. Participants (n = 722 veterinary-clinic staff (VS); n = 1028 dog owners (DOs)) completed an online survey assessing: (a) the perceived importance of PA for promoting health and preventing disease, (b) willingness to participate in a veterinary-prescribed PA program, and (c) potential benefits and barriers of such a program. Both groups of participants indicated that PA is important for both human and animal health (97% and 98% of VS and 92% and 93% of DOs said PA is very or extremely important for animal and human health, respectively). Additionally, most participants in both groups expressed an interest in participating in a veterinary-prescribed PA program in the future, with only 11% of DOs and 10% of VS saying they were not interested. Benefits and barriers of this type of intervention for both practitioners and patients were also identified. Incorporating veterinary-prescribed PA programming into veterinary clinics seems to be acceptable to both DOs and VS. Additionally, many VS believe such programming would be feasible at their clinics; thus, pursuing such programs appears to be a promising avenue for promoting human and animal health.

Phosphorylation of l-serine-containing enkephalin analogs has been explored as an alternative to glycosylation in an effort to increase blood-brain barrier permeability and CNS bioavailability of peptide pharmacophores. Two enkephalin-based peptides were modified for these studies, a set related to DTLES, a mixed µ/δ-agonist, and one related to DAMGO, a highly selective µ-agonist. Each unglycosylated peptide was compared to its phosphate, its mono-benzylphosphate ester, and its ß-d-glucoside. Binding was characterized in membrane preparations from Chinese hamster ovary cells expressing human µ, δ and κ-opiate receptors. Antinociception was measured in mice using the 55 °C tail-flick assay. To estimate bioavailability, the antinociceptive effect of each opioid agonist was evaluated after intracerebroventricular (i.c.v.) or intravenous administration (i.v.) of the peptides. Circular dichroism methods and high-field nuclear magnetic resonance were used in the presence and absence of sodium dodecylsulfate to understand how the presence of a membrane might influence the peptide conformations.

Today's biobanks must work to take full advantage of collected samples, while maximizing sample quality and minimizing costs to sustain operations for a long period of time. This is a tall order that will require collaboration and compromise for both end-users and collection sites. This article discusses the efforts of the Génome Québec-Centre Hospitalier Affilié Universitaire Régional de Chicoutimi Biobank to fractionate blood samples for the simultaneous preservation of plasma and DNA-containing layers while minimizing resources required for shipping and transport. This article also describes methods for successful reproducible application of the plasma-depleted blood sample to GenPlates (GenVault, Carlsbad, CA).
RESUMO
Bone morphogenetic protein-15 (BMP-15) and growth and differentiation factor-9 (GDF-9) are oocyte-secreted factors that play essential roles in human folliculogenesis and ovulation. Their bioactivity is tightly regulated through phosphorylation, likely to occur within the Golgi apparatus of the secretory pathway. Here we show that Golgi apparatus casein kinase (G-CK) catalyzes the phosphorylation of rhBMP-15 and rhGDF-9. rhBMP-15, in particular, is an excellent substrate for G-CK. In each protein a single residue is phosphorylated by G-CK, corresponding to the serine residue at the sixth position of the mature region of both rhBMP-15 and rhGDF-9, whose phosphorylation is required for biological activity.

Two technologies for dry-state, ambient temperature transport of biospecimens were evaluated in this study. Umbilical cord blood (UCB) samples from 4 individuals were transported at ambient temperature using GenPlates, and the DNA recovered was compared with DNA purified directly from granulocytes of the same UCB samples. GenTegra™ DNA tubes were then used to transport the DNA from California to North Carolina and New Zealand, either immediately after drying or following 30 days of storage at 25°C and 76°C. The integrity of the recovered DNA was thoroughly tested using 2 human leukocyte antigens (HLA)-typing techniques (bead array and sequencing), as well as microarray-based whole-genome scanning. HLA-typing results were the same for all samples whether the DNA had been stored for 3 days during transport or 30 days at either 25°C or 76°C. There were no differences in the HLA-typing results of DNA recovered from UCB samples stored in GenPlates compared with DNA extracted directly from granulocytes. Moreover, the microarray analysis revealed call rates of >99.5% for every sample, regardless of storage method, with a statistical concordance of 99.99% between the UCB samples stored in GenPlates compared with DNA extracted directly from granulocytes. These results indicate that both GenPlates and GenTegra are viable methods of storing and transporting UCB (stem cell) biospecimens in a dry state. The quality and quantity of DNA recovered using both technologies are sufficient for complex genotyping using a number of different methods.
