Gastrointestinal hemorrhage is a common cause of hospital admission. However, there are little data to inform practice around blood count monitoring-a cornerstone of management. We hypothesized that more frequent testing leads to increased resource utilization without improvement in patient outcomes.
This retrospective observational cohort study examined all patients admitted to a large academic medical institution primarily for gastrointestinal bleeding between July 10, 2014, and January 1, 2018. We identified 1150 patients admitted for gastrointestinal hemorrhage. SL-327 Patients under 18, who developed bleeding while hospitalized, or who were transferred were excluded. The primary outcome was the number of complete blood counts collected in the first 48 hours of admission. Propensity matched analysis was performed to assess blood transfusion, units of blood transfused, time-to-endoscopy, mortality, and 30-day readmission rate.
On average, 5.6 complete blood counts were collected in the first 48 hours; 67% of the cohort was transfused (average of 2.6 units of packed red blood cells). When matched for comorbidity, anticoagulant use, location (ward vs. intensive care unit), vital signs, hemoglobin level, and international normalized ratio, patients having more frequent monitoring had similar hospital length of stay and mortality rates, but were more likely to receive a blood transfusion (0.93 vs 0.76, P < .05), and if transfused, receive more blood (4 vs 2 units, P < .05).
Blood count monitoring occurs more frequently than is likely necessary, is associated with a higher likelihood of blood transfusion, and does not affect patient outcomes, suggesting patient care may be improved by less frequent monitoring.

In this study, by screening a mutant library, a gene related with bicarbonate transport, slr1512, was found involved in HL acclimation in model cyanobacterium Synechocystis sp. PCC 6803. Comparative growth analysis showed that the slr1512 knockout mutant dramatically enhanced the tolerance of Synechocystis towards long-term HL stress (200 μmol photons m-2 s-1) than the wild type, achieving an enhanced growth by ~1.95-folds after 10 d. The phenotype differences between Δslr1512 and the wild type were analyzed via absorption spectrum and chlorophyll a content measurement. In addition, the accessible bicarbonate controlled by slr1512 and decreased PSII activity were demonstrated, and they were found to be the key factors affecting the tolerance of Synechocystis against HL stress. Further analysis confirmed that intracellular bicarbonate can significantly affect the activity of photosystem II, leading to the altered accumulation of toxic ROS under HL. Finally, a comparative transcriptomics was applied to determine the differential responses to HL between Δslr1512 and the wild type. This work provides useful insights to long-term acclimation mechanisms towards HL and valuable information to guide the future tolerance engineering of cyanobacteria against HL.
Adverse mental health consequences of COVID-19, including anxiety and depression, have been widely predicted but not yet accurately measured. There are a range of physical health risk factors for COVID-19, but it is not known if there are also psychiatric risk factors. In this electronic health record network cohort study using data from 69 million individuals, 62 354 of whom had a diagnosis of COVID-19, we assessed whether a diagnosis of COVID-19 (compared with other health events) was associated with increased rates of subsequent psychiatric diagnoses, and whether patients with a history of psychiatric illness are at a higher risk of being diagnosed with COVID-19.
We used the TriNetX Analytics Network, a global federated network that captures anonymised data from electronic health records in 54 health-care organisations in the USA, totalling 69·8 million patients. TriNetX included 62 354 patients diagnosed with COVID-19 between Jan 20, and Aug 1, 2020. We created cohorts of patients who had been diagnos14 to 90 days after COVID-19 diagnosis was 18·1% (95% CI 17·6-18·6), including 5·8% (5·2-6·4) that were a first diagnosis. The incidence of a first diagnosis of dementia in the 14 to 90 days after COVID-19 diagnosis was 1·6% (95% CI 1·2-2·1) in people older than 65 years. A psychiatric diagnosis in the previous year was associated with a higher incidence of COVID-19 diagnosis (relative risk 1·65, 95% CI 1·59-1·71; p<0·0001). This risk was independent of known physical health risk factors for COVID-19, but we cannot exclude possible residual confounding by socioeconomic factors.
Survivors of COVID-19 appear to be at increased risk of psychiatric sequelae, and a psychiatric diagnosis might be an independent risk factor for COVID-19. Although preliminary, our findings have implications for clinical services, and prospective cohort studies are warranted.

Loneliness is experienced by a third of older adults in the UK and is a modifiable potential risk factor for depressive symptoms. It is unclear how the association between loneliness and depressive symptoms persists over time, and whether it is independent of related social constructs and genetic confounders. We aimed to investigate the association between loneliness and depressive symptoms, assessed on multiple occasions during 12 years of follow-up, in a large, nationally representative cohort of adults aged 50 years and older in England.
We did a longitudinal study using seven waves of data that were collected once every 2 years between 2004 and 2017, from adults aged 50 years and older in the English Longitudinal Study of Ageing (ELSA). The exposure was loneliness at baseline (wave two), measured with the short 1980 revision of the University of California, Los Angeles Loneliness Scale (R-UCLA). The primary outcome was a score indicating severity of depression measured at six subsequent timepoints (wainated. Associations between loneliness and depressive symptoms remained after 12 years of follow-up, although effect sizes were smaller with longer follow-up.
Irrespective of other social experiences, higher loneliness scores at baseline were associated with higher depression symptom severity scores during 12 years of follow-up among adults aged 50 years and older. Interventions that reduce loneliness could prevent or reduce depression in older adults, which presents a growing public health problem worldwide.

All experimental data, from different phospholipid-copolymer compositions, concentrations and temperatures are fitted with one model. This model allows the determination of the separate contributions from vesicular populations of different lamellarity and size. MPOx copolymers are proved to modify both the size and lamellarity of DPPC liposomes. The gradient copolymer with higher hydrophilic content induces shrinkage of the uni- and bi-lamellar DPPC vesicles. The copolymer with lower hydrophilic content causes dramatic changes on the lamellarity of DPPC vesicles by the formation of hexa-lamellar vesicles. The tendency of multi-lamellar vesicles to transform into uni-lamellar ones as temperature increases is more pronounced in the presence of the copolymers. These findings may have direct implications on the drug loading and release properties of liposomes and their interactions with cells.The spread of acquired drug resistance and of microorganisms naturally resistant to antibiotics is a major threat to global health, leading to an urgent need for novel antimicrobial compounds. Exogenous nitric oxide (NO) represents an attractive and promising antimicrobial approach, showing both bactericidal and biofilm dispersal activities. Numerous studies have been performed to develop NO donor scaffolds, including small molecules, macromolecular compounds, nanoparticles (NPs), and polymeric materials. This approach has resulted in successful outcomes, with some NO-releasing compounds entering clinical practice. In this review, we highlight the importance of this strategy, with a focus on lung infections.
To estimate the effect of skin-to-skin care (SSC) on biobehavioral measures of stress (anxiety and salivary cortisol) and attachment (attachment scores and salivary oxytocin) of mothers before and after their infants' neonatal cardiac surgery.
A prospective interventional, baseline response-paired pilot study.
Cardiac center of a large, metropolitan, freestanding children's hospital.
Thirty women whose infants were hospitalized for neonatal cardiac surgery.
Participants acted as their own controls before, during, and after SSC at two time points once before and once after surgery. We measured the stress response of mothers, as indicated by self-reported scores of anxiety and maternal salivary cortisol, and maternal-infant attachment, as indicated by self-reported scores and maternal salivary oxytocin.
Significant reductions in self-reported scores of anxiety and salivary cortisol were found as a result of SSC at each time point, as well as increased self-reported attachment. No significant differences were found in oxytocin.
Our findings provide initial evidence of the benefits of SSC as a nurse-led intervention to support maternal attachment and reduce physiologic and psychological stress responses in mothers of infants with critical congenital heart disease before and after neonatal cardiac surgery.

As our understanding of T cell metabolism increases, so does our appreciation of its inherent complexity. The metabolic heterogeneity of T cells that reside in different locations, such as lymphoid and non-lymphoid tissues, presents a challenge to developing therapies that exploit metabolic vulnerabilities. The roots of metabolic heterogeneity are only beginning to be understood. Here, we propose four factors that contribute to the adaptation of T cells to their dynamic tissue environment (1) functional status of T cells, (2) local factors unique to the tissue niche, (3) type of inflammation, and (4) time spent in a specific tissue. We review emerging concepts about tissue-specific metabolic reprogramming in T cells with particular attention to explain how such metabolic properties are used as an adaptation mechanism. Adaptation of immune cells to the local microenvironment is critical for their persistence and function. Here, Varanasi et al.
