Decoding the ocean's microbiological secrets for marine enzyme biodiscovery

A global census of marine microbial life has been underway over the past several decades. During this period, there have been scientific breakthroughs in estimating microbial diversity and understanding microbial functioning and ecology. It is estimated that the ocean, covering 71% of the earth's surface with its estimated volume of about 2 x 10(18) m(3) and an average depth of 3800 m, hosts the largest population of microbes on Earth. More than 2 million eukaryotic and prokaryotic species are thought to thrive both in the ocean and on its surface. Prokaryotic cell abundances can reach densities of up to 10(12) cells per millilitre, exceeding eukaryotic densities of around 10(6) cells per millilitre of seawater. Besides their large numbers and abundance, marine microbial assemblages and their organic catalysts (enzymes) have a largely underestimated value for their use in the development of industrial products and processes. In this perspective article, we identified critical gaps in knowledge and technology to fast-track this development. We provided a general overview of the presumptive microbial assemblages in oceans, and an estimation of what is known and the enzymes that have been currently retrieved. We also discussed recent advances made in this area by the collaborative European Horizon 2020 project 'INMARE'

Long-term outcomes of the global tuberculosis and COVID-19 co-infection cohort

Background: Longitudinal cohort data of patients with tuberculosis (TB) and coronavirus disease 2019 (COVID-19) are lacking. In our global study, we describe long-term outcomes of patients affected by TB and COVID-19. Methods: We collected data from 174 centres in 31 countries on all patients affected by COVID-19 and TB between 1 March 2020 and 30 September 2022. Patients were followed-up until cure, death or end of cohort time. All patients had TB and COVID-19; for analysis purposes, deaths were attributed to TB, COVID-19 or both. Survival analysis was performed using Cox proportional risk-regression models, and the log-rank test was used to compare survival and mortality attributed to TB, COVID-19 or both. Results: Overall, 788 patients with COVID-19 and TB (active or sequelae) were recruited from 31 countries, and 10.8% (n=85) died during the observation period. Survival was significantly lower among patients whose death was attributed to TB and COVID-19 versus those dying because of either TB or COVID-19 alone (p<0.001). Significant adjusted risk factors for TB mortality were higher age (hazard ratio (HR) 1.05, 95% CI 1.03-1.07), HIV infection (HR 2.29, 95% CI 1.02-5.16) and invasive ventilation (HR 4.28, 95% CI 2.34-7.83). For COVID-19 mortality, the adjusted risks were higher age (HR 1.03, 95% CI 1.02-1.04), male sex (HR 2.21, 95% CI 1.24-3.91), oxygen requirement (HR 7.93, 95% CI 3.44-18.26) and invasive ventilation (HR 2.19, 95% CI 1.36-3.53). Conclusions: In our global cohort, death was the outcome in >10% of patients with TB and COVID-19. A range of demographic and clinical predictors are associated with adverse outcomes

The bone-degrading enzyme machinery: From multi-component understanding to the treatment of residues from the meat industry

Highlights: • Characterization of enzymes from bone-degrading marine microbiomes. • Enzymes degrade sialo/glyco-proteins at multiple conditions of pH and temperatures. • Enzyme cocktails are useful for valorising bone residues in biorefinery industry. Abstract: Many microorganisms feed on the tissue and recalcitrant bone materials from dead animals, however little is known about the collaborative effort and characteristics of their enzymes. In this study, microbial metagenomes from symbionts of the marine bone-dwelling worm Osedax mucofloris, and from microbial biofilms growing on experimentally deployed bone surfaces were screened for specialized bone-degrading enzymes. A total of 2,043 taxonomically (closest match within 40 phyla) and functionally (1 proteolytic and 9 glycohydrolytic activities) diverse and non-redundant sequences (median pairwise identity of 23.6%) encoding such enzymes were retrieved. The taxonomic assignation and the median identity of 72.2% to homologous proteins reflect microbial and functional novelty associated to a specialized bone-degrading marine community. Binning suggests that only one generalist hosting all ten targeted activities, working in synergy with multiple specialists hosting a few or individual activities. Collagenases were the most abundant enzyme class, representing 48% of the total hits. A total of 47 diverse enzymes, representing 8 hydrolytic activities, were produced in Escherichia coli, whereof 13 were soluble and active. The biochemical analyses revealed a wide range of optimal pH (4.0–7.0), optimal temperature (5–65 °C), and of accepted substrates, specific to each microbial enzyme. This versatility may contribute to a high environmental plasticity of bone-degrading marine consortia that can be confronted to diverse habitats and bone materials. Through bone-meal degradation tests, we further demonstrated that some of these enzymes, particularly those from Flavobacteriaceae and Marinifilaceae, may be an asset for development of new value chains in the biorefinery industry

Appropriateness of antiplatelet therapy for primary and secondary cardio- and cerebrovascular prevention in acutely hospitalized older people

Aims: Antiplatelet therapy is recommended for the secondary prevention of cardio- and cerebrovascular disease, but for primary prevention it is advised only in patients at very high risk. With this background, this study aims to assess the appropriateness of antiplatelet therapy in acutely hospitalized older people according to their risk profile. Methods: Data were obtained from the REPOSI register held in Italian and Spanish internal medicine and geriatric wards in 2012 and 2014. Hospitalized patients aged ≥65 assessable at discharge were selected. Appropriateness of the antiplatelet therapy was evaluated according to their primary or secondary cardiovascular prevention profiles. Results: Of 2535 enrolled patients, 2199 were assessable at discharge. Overall 959 (43.6%, 95% CI 41.5–45.7) were prescribed an antiplatelet drug, aspirin being the most frequently chosen. Among patients prescribed for primary prevention, just over half were inappropriately prescribed (52.1%), being mainly overprescribed (155/209 patients, 74.2%). On the other hand, there was also a high rate of inappropriate underprescription in the context of secondary prevention (222/726 patients, 30.6%, 95% CI 27.3–34.0%). Conclusions: This study carried out in acutely hospitalized older people shows a high degree of inappropriate prescription among patients prescribed with antiplatelets for primary prevention, mainly due to overprescription. Further, a large proportion of patients who had had overt cardio- or cerebrovascular disease were underprescribed, in spite of the established benefits of antiplatelet drugs in the context of secondary prevention

Risk factors for three-month mortality after discharge in a cohort of non-oncologic hospitalized elderly patients: Results from the REPOSI study

Background: Short-term prognosis, e.g. mortality at three months, has many important implications in planning the overall management of patients, particularly non-oncologic patients in order to avoid futile practices. The aims of this study were: i) to investigate the risk of three-month mortality after discharge from internal medicine and geriatric wards of non-oncologic patients with at least one of the following conditions: permanent bedridden status during the hospital stay; severely reduced kidney function; hypoalbuminemia; hospital admissions in the previous six months; severe dementia; ii) to establish the absolute risk difference of three-month mortality of bedridden compared to non-bedridden patients. Methods: This prospective cohort study was run in 102 Italian internal medicine and geriatric hospital wards. The sample included all patients with three-months follow-up data. Bedridden condition was defined as the inability to walk or stand upright during the whole hospital stay. The following parameters were also recorded: estimated GFR <= 29 mL/min/1.73 m(2); severe dementia; albuminemia << 2.5 g/dL; hospital admissions in the six months before the index admission. Results: Of 3915 patients eligible for the analysis, three-month follow-up were available for 2058, who were included in the study. Bedridden patients were 112 and the absolute risk difference of mortality at three months was 0.13 (CI 95% 0.08-0.19, p << 0.0001). Logistic regression analysis also adjusted for age, sex, number of drugs and comorbidity index found that bedridden condition (OR 2.10, CI 95% 1.12-3.94), severely reduced kidney function (OR 2.27, CI 95% 1.22-4.21), hospital admission in the previous six months (OR 1.96, CI 95% 1.22-3.14), severe dementia (with total or severe physical dependence) (OR 4.16, CI 95% 2.39-7.25) and hypoalbuminemia (OR 2.47, CI 95% 1.12-5.44) were significantly associated with higher risk of three-month mortality. Conclusions: Bedridden status, severely reduced kidney function, recent hospital admissions, severe dementia and hypoalbuminemia were associated with higher risk of three-month mortality in non-oncologic patients after discharge from internal medicine and geriatric hospital wards

Prognostic value of degree and types of anaemia on clinical outcomes for hospitalised older patients

Study objective This study investigated in a large sample of in-patients the impact of mild-moderate-severe anaemia on clinical outcomes such as in-hospital mortality, re-admission, and death within three months after discharge. Methods A prospective multicentre observational study, involving older people admitted to 87 internal medicine and geriatric wards, was done in Italy between 2010 and 2012. The main clinical/laboratory data were obtained on admission and discharge. Based on haemoglobin (Hb), subjects were classified in three groups: group 1 with normal Hb, (reference group), group 2 with mildly reduced Hb (10.0–11.9 g/dL in women; 10.0–12.9 g/dL in men) and group 3 with moderately-severely reduced Hb (<10 g/dL in women and men). Results Patients (2678; mean age 79.2 ± 7.4 y) with anaemia (54.7%) were older, with greater functional impairment and more comorbidity. Multivariable analysis showed that mild but not moderate-severe anaemia was associated with a higher risk of hospital re-admission within three months (group 2: OR = 1.62; 95%CI 1.21–2.17). Anaemia failed to predict in-hospital mortality, while a higher risk of dying within three months was associated with the degree of Hb reduction on admission (group 2: OR = 1.82;95%CI 1.25–2.67; group 3: OR = 2.78;95%CI 1.82–4.26) and discharge (group 2: OR = 2.37;95%CI 1.48–3.93; group 3: OR = 3.70;95%CI 2.14–6.52). Normocytic and macrocytic, but not microcytic anaemia, were associated with adverse clinical outcomes. Conclusions Mild anaemia predicted hospital re-admission of older in-patients, while three-month mortality risk increased proportionally with anaemia severity. Type and severity of anaemia affected hospital re-admission and mortality, the worst prognosis being associated with normocytic and macrocytic anaemia

Pattern of in-hospital changes in drug use in the older people from 2010 to 2016

Purpose: To assess the pattern of in-hospital changes in drug use in older patients from 2010 to 2016. Methods: People aged 65 years or more acutely hospitalized in those internal medicine and geriatric wards that did continuously participate to the REgistro POliterapie Società Italiana di Medicina Interna register from 2010 to 2016 were selected. Drugs use were categorized as 0 to 1 drug (very low drug use), 2 to 4 drugs (low drug use), 5 to 9 drugs (polypharmacy), and 10 or more drugs (excessive polypharmacy). To assess whether or not prevalence of patients in relation to drug use distribution changed overtime, adjusted prevalence ratios (PRs) was estimated with log-binomial regression models. Results: Among 2120 patients recruited in 27 wards continuously participating to data collection, 1882 were discharged alive and included in this analysis. The proportion of patients with very low drug use (0-1 drug) at hospital discharge increased overtime, from 2.7% in 2010 to 9.2% in 2016. Results from a log-logistic adjusted model confirmed the increasing PR of these very low drug users overtime (particularly in 2014 vs 2012, PR 1.83 95% CI 1.14-2.95). Moreover, from 2010 to 2016, there was an increasing number of patients who, on polypharmacy at hospital admission, abandoned it at hospital discharge, switching to the very low drug use group. Conclusion: This study shows that in internal medicine and geriatric wards continuously participating to the REgistro POliterapie Società Italiana di Medicina Interna register, the proportion of patients with a very low drug use at hospital discharge increased overtime, thus reducing the therapeutic burden in this at risk population

Prognostic relevance of glomerular filtration rate estimation obtained through different equations in hospitalized elderly patients

The estimated glomerular filtration rate (eGFR) is a predictor of important outcomes and its reduction has been associated with the risk of all-cause mortality in both general population and elderly patients. However while reduced renal function is common in older people, the best method for estimating GFR remains unclear, especially in an acute care setting. Most studies analyzing the accuracy of eGFR in the elderly were carried out in different heterogeneous settings. In this study, we compare the prognostic value of different formulas estimating GFR in predicting the risk of in-hospital morbidity and mortality within 3 months from discharge in elderly hospitalized patients. Data were extracted from \u201cRegistro Politerapia Societ\ue0 Italiana di Medicina Interna (REPOSI)\u201d. Patients with available creatinine values at hospital admission were selected and eGFR was calculated according to the different formulas: Cockcroft-Gault, Modification of Diet in Renal Disease equation, Chronic Kidney Disease Epidemiology Collaboration, Berlin Initiative Study and Full Age Spectrum. 4621 patients were included in the analysis. Among these, 4.2% and 14.2% died during hospitalization and within 3 months from discharge, respectively. eGFR &gt; 60 ml/min/1.73 m2 at admission was associated with a very low risk of mortality during the hospital stay and within 90 days from discharge, while an eGFR &lt; 60 ml/min/1.73 m2 was associated with unfavorable outcomes, although with a poor level of accuracy (AUC 0.60\u20130.66). No difference in predictive power between different equations was found. Physicians should be aware of the prognostic role of eGFR in a comprehensive assessment of elderly in-patients
