Probiotics Reduce Inflammation in Antiretroviral Treated, HIV-Infected Individuals: Results of the "Probio-HIV" Clinical Trial

BACKGROUND: HIV infection results in damage to the gastrointestinal (GI) tract, microbial translocation and immune activation. These are not completely normalized with combined antiretroviral therapy (cART). Moreover, increate morbidity and mortality of cART-treated HIV-infected individuals is associated with inflammation. METHODS: In order to enhance GI tract immunity, we recruited and treated 20 HIV-infected humans with cART supplemented with probiotics and followed inflammation and immunological parameters (clinical trial number NCT02164344). 11 HIV seronegative subjects were included as control group. The enumeration of CD4+, CD8+, CD38+ and HLA-DR+ lymphocytes were evaluated on peripheral blood; HIV-RNA levels, sCD14, d-dimer, C-reactive protein (CRP) high sensitivity C-reactive protein (hsCRP), IL-6 and Lipopolysaccharide Binding Protein (LBP) were assayed on plasma. RESULTS: We observe that cART does not normalize the levels of immune activation in HIV positive patients anyway inflammation and markers of microbial translocation were significantly reduced with probiotic supplementation. Patients show a clear and statistically significant reduction in the levels of immune activation on CD4 T-lymphocytes, for both markers CD38 and HLA-DR and their simultaneous expression, LBP and hsCRP plasma levels after probiotic diet supplementation settling to values comparable to controls. CONCLUSIONS: Supplementing cART with probiotics in HIV-infected individuals may improve GI tract immunity and there by mitigate inflammatory sequelae, ultimately improving prognosis

Comparison between hospitalized patients affected or not by COVID-19 (RESILIENCY study)

Dear Editor, in the recent report of Munblit and coworkers [1], authors observed that the combination of clinical features was sufficient to diagnose COVID-19 indicating that laboratory testing is not critical in real-life clinical practice. To date, all patients admitted to Emergency Department with acute respiratory failure and/or fever should be considered as a suspected SARS-CoV-2 infection [2-3], and an early recognition of etiology and the prompt therapeutic management are crucial to improve survival [4-5]. From March to July 2020, we performed a prospective, multicenter study (RESILIENCY study). During the study period, all patients hospitalized for suspected or confirmed COVID-19 were prospectively recruited in 3 large hospitals in Rome, Italy. All patients with suspected SARS-CoV-2 infection, admitted to the hospital in case of fever and/or hypoxemic respiratory failure (PaO2 <60 mmHg at rest in ambient air) or of exacerbation of underlying diseases or severe symptoms not manageable outside the hospital, were evaluated according to a predefined protocol (see Figure 1). Overall, 653 patients were included in the study: 309 (47.3%) patients with confirmed COVID-19 and 344 (52.7%) without COVID-19, hospitalized for other causes. Baseline characteristics and outcomes of the study population showed that the main causes of hospitalization among patients without COVID-19 were: acute heart failure (47%), bacterial pneumonia (38.5%), and pulmonary embolism (9.2%). Overall, 67 (21.7%) patients of COVID-19 group and 45 (13.1%) hospitalized for other causes were admitted to intensive care unit; 30-day mortality was observed in 59 (19%) patients of COVID-19 group and 62 (18%) of non-COVID-19 group. The multivariate analysis about risk factors for COVID-19 etiology at time of hospitalization showed that dry cough (OR 3.76, CI 95% 1.98-7.92, P<0.001), duration of fever>3 days (OR 5.21, CI 95% 2.34-9.21, P<0.001), lymphocytopenia (OR 1.98, CI 95% Downloaded from https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciaa1745/5989494 by Sapienza Università di Roma user on 01 December 2020 Accepted Manuscript 3 1.27-4.22, P=0.002) and PaO2/FiO2 ratio<250 (OR 4.98, CI 95% 2.22-9.71, P<0.001) were independently associated with COVID-19 etiology, while procalcitonin value>1 ng/ mL (OR 0.21, CI 95% 0.08-0.82, p<0.001), and lactate>2 mmol/L (OR 0.41, CI 95% 0.15-0.77, p<0.001) were associated with non-COVID-19 etiology. Finally, analysis about predictors of 30-day mortality showed that age (per-year increase OR 1.33; CI 95% 1.11-2.10; p<0.001), cardiovascular disease (OR 4.58; CI 95% 2.07-8.25; p<0.001), and ICU admission (OR 2.1; CI 95% 1.48-4.4; p<0.001) were independently associated with all-cause 30-day mortality, while the use of low-molecularweight heparin (OR 0.22, CI 95% 0.03-0.45, p=0.002) was associated with survival. The findings of the present study can be summarized as follows:1) the prompt identification of specific clinical characteristics (like dry cough or duration of fever>3 days), and laboratory findings (like lymphocytopenia, PaO2/FiO2 ratio<250, procalcitonin value>1 ng/ mL, and lactate>2 mmol/L) can help physicians to distinguish rapidly between COVID19 or other etiologies [6]; 2) the application of a standard approach to management of patients with acute respiratory failure and/or fever associated with the knowledge of clinical and laboratory characteristics of COVID-19 can early drive physicians to therapeutic choices; and 3) age, cardiovascular disease, and ICU admission show an independent association with all-cause 30-day mortality [7], while the use of low-molecular-weight heparin was associated with survival [8]. In conclusion, COVID-19 syndrome is characterized by a heterogeneous clinical, laboratoristic, and radiological presentation, especially at its onset [9]. However, the application of a standard approach to management of patients with acute respiratory failure and/or fever and the knowledge of clinical and laboratory characteristics of COVID-19 can early drive therapeutic choic

Safety and efficacy of treatment with vitamin K antagonists in patients managed in a network of anticoagulation services or as routine general care

This is a retrospective, record-linkage study aimed at comparing the effectiveness and safety of two management models of vitamin K antagonists: a Network model (NAS), in which anticoagulation clinics and general practitioners (GP) share the same management software and database, and an individual General Practitioners model. Main outcomes were thromboembolic events (TE), major bleeding (MB) and all-cause mortality. Crude incidence rate and sub-distribution hazard ratio were calculated. Fine and Grey models were used to calculate SHR in multi-variable analysis. 9,418 patients in the NAS and 5,508 in the Routine General Care (RGC) cohort were included. Patients in the NAS cohort had a lower incidence of TE and mortality in respect to the RGC (sHR 0.76%, 95% CI 0.64-0.90 and 0.82%, 95% CI 0.75-0.89, respectively). More patients in the NAS than in the RGC cohort attained a Time in Therapeutic Range >60% (62.2% vs 35.7%, p<0.001). No statistically significant difference was found in MB incidence. This study shows that the NAS model for vitamin K antagonist oral anticoagulants management significantly improves the TTR and reduces the incidence of TE and mortality, without affecting the MB rate

Opinions, positions and experiences of members of the Argentine Anthropology Society concerning the impact of mega-mining on society and heritage

Entre el 23 de febrero y el 20 de abril de 2012, la Sociedad Argentina de Antropología abrió una convocatoria a sus 700 socios para conocer sus opiniones, posiciones y experiencias acerca de los megaproyectos de minería. La iniciativa surgió como producto de la solicitud de uno de los miembros de la SAA, preocupado por los conflictos ocurridos en las provincias cordilleranas de La Rioja, Catamarca y Tucumán a raíz de la instalación de grandes emprendimientos mineros. Las discusiones en torno a este tema tienen larga data en la ciudadanía, pero en esta última década y, en especial, en estos últimos meses, habían cobrado un lugar destacado tanto por la magnitud e implicancia de aquellos eventos como por el alcance mediático que tuvo la problemática a escala nacional. En ese marco, quienes conformamos la Comisión Directiva expresamos públicamente nuestro repudio a los hechos de violencia y represión acaecidos ante las manifestaciones de protesta ocurridas sobre poblaciones del Noroeste argentino y reconocimos las transformaciones que sobre la vida social, económica, cultural, ecológica y política generan estos emprendimientos. Pero además, consideramos oportuna aquella solicitud y decidimos invitar a todos los socios a manifestar sus opiniones al respecto.Sociedad Argentina de Antropologí

Prognosis of screen-detected breast cancers: results of a population based study

BACKGROUND: The reduced mortality rate from breast carcinoma among women offered screening mammography is demonstrated after 15–20 years of follow-up. However, the assessment of 5-year overall and event-free survival could represent an earlier measure of the efficacy of mammography screening program (MSP). METHODS: All cases of breast cancer diagnosed in the Province of Modena between years 1996 and 2000 in women aged 50 to 69 years, were identified through the Modena Cancer Registry (MCR). Stage of disease and treatment information were obtained from clinical records. All the events occurring up to June 30, 2003 were retrieved by experienced monitors. Five-year overall and event-free survival were the principal end-points of the study. RESULTS: During a 5-year period, 587 primary breast cancers were detected by the MSP and 471 primary breast cancers were diagnosed out of the MSP. The screen-detected breast cancers were smaller, more likely node negative, with low histological grade, low proliferative activity and positive receptors status. Furthermore, the breast cancer diagnosed through the MSP more frequently received a conservative surgery. The 5-year survival rate was 94% in the screen-detected group, versus 84% in the other group (p = 0.0001). The rate of 5-year event-free survival was 89% and 75% for the MSP participants and not participants, respectively (p = 0.0001). CONCLUSIONS: Our data confirm a favourable outcome of screen-detected breast cancers in terms of five-year overall and event-free survival, which reflect the good quality assurance parameters of the MSP. Finally, a cancer registry should be implemented in every area covered by screening programs

Beta-Blocker Use in Older Hospitalized Patients Affected by Heart Failure and Chronic Obstructive Pulmonary Disease: An Italian Survey From the REPOSI Register

Beta (β)-blockers (BB) are useful in reducing morbidity and mortality in patients with heart failure (HF) and concomitant chronic obstructive pulmonary disease (COPD). Nevertheless, the use of BBs could induce bronchoconstriction due to β2-blockade. For this reason, both the ESC and GOLD guidelines strongly suggest the use of selective β1-BB in patients with HF and COPD. However, low adherence to guidelines was observed in multiple clinical settings. The aim of the study was to investigate the BBs use in older patients affected by HF and COPD, recorded in the REPOSI register. Of 942 patients affected by HF, 47.1% were treated with BBs. The use of BBs was significantly lower in patients with HF and COPD than in patients affected by HF alone, both at admission and at discharge (admission, 36.9% vs. 51.3%; discharge, 38.0% vs. 51.7%). In addition, no further BB users were found at discharge. The probability to being treated with a BB was significantly lower in patients with HF also affected by COPD (adj. OR, 95% CI: 0.50, 0.37-0.67), while the diagnosis of COPD was not associated with the choice of selective β1-BB (adj. OR, 95% CI: 1.33, 0.76-2.34). Despite clear recommendations by clinical guidelines, a significant underuse of BBs was also observed after hospital discharge. In COPD affected patients, physicians unreasonably reject BBs use, rather than choosing a β1-BB. The expected improvement of the BB prescriptions after hospitalization was not observed. A multidisciplinary approach among hospital physicians, general practitioners, and pharmacologists should be carried out for better drug management and adherence to guideline recommendations

Antidiabetic Drug Prescription Pattern in Hospitalized Older Patients with Diabetes

Objective: To describe the prescription pattern of antidiabetic and cardiovascular drugs in a cohort of hospitalized older patients with diabetes. Methods: Patients with diabetes aged 65 years or older hospitalized in internal medicine and/or geriatric wards throughout Italy and enrolled in the REPOSI (REgistro POliterapuie SIMI—Società Italiana di Medicina Interna) registry from 2010 to 2019 and discharged alive were included. Results: Among 1703 patients with diabetes, 1433 (84.2%) were on treatment with at least one antidiabetic drug at hospital admission, mainly prescribed as monotherapy with insulin (28.3%) or metformin (19.2%). The proportion of treated patients decreased at discharge (N = 1309, 76.9%), with a significant reduction over time. Among those prescribed, the proportion of those with insulin alone increased over time (p = 0.0066), while the proportion of those prescribed sulfonylureas decreased (p &lt; 0.0001). Among patients receiving antidiabetic therapy at discharge, 1063 (81.2%) were also prescribed cardiovascular drugs, mainly with an antihypertensive drug alone or in combination (N = 777, 73.1%). Conclusion: The management of older patients with diabetes in a hospital setting is often sub-optimal, as shown by the increasing trend in insulin at discharge, even if an overall improvement has been highlighted by the prevalent decrease in sulfonylureas prescription

The “Diabetes Comorbidome”: A Different Way for Health Professionals to Approach the Comorbidity Burden of Diabetes

(1) Background: The disease burden related to diabetes is increasing greatly, particularly in older subjects. A more comprehensive approach towards the assessment and management of diabetes’ comorbidities is necessary. The aim of this study was to implement our previous data identifying and representing the prevalence of the comorbidities, their association with mortality, and the strength of their relationship in hospitalized elderly patients with diabetes, developing, at the same time, a new graphic representation model of the comorbidome called “Diabetes Comorbidome”. (2) Methods: Data were collected from the RePoSi register. Comorbidities, socio-demographic data, severity and comorbidity indexes (Cumulative Illness rating Scale CIRS-SI and CIRS-CI), and functional status (Barthel Index), were recorded. Mortality rates were assessed in hospital and 3 and 12 months after discharge. (3) Results: Of the 4714 hospitalized elderly patients, 1378 had diabetes. The comorbidities distribution showed that arterial hypertension (57.1%), ischemic heart disease (31.4%), chronic renal failure (28.8%), atrial fibrillation (25.6%), and COPD (22.7%), were the more frequent in subjects with diabetes. The graphic comorbidome showed that the strongest predictors of death at in hospital and at the 3-month follow-up were dementia and cancer. At the 1-year follow-up, cancer was the first comorbidity independently associated with mortality. (4) Conclusions: The “Diabetes Comorbidome” represents the perfect instrument for determining the prevalence of comorbidities and the strength of their relationship with risk of death, as well as the need for an effective treatment for improving clinical outcomes

Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both

Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population

Prescription appropriateness of anti-diabetes drugs in elderly patients hospitalized in a clinical setting: evidence from the REPOSI Register

Diabetes is an increasing global health burden with the highest prevalence (24.0%) observed in elderly people. Older diabetic adults have a greater risk of hospitalization and several geriatric syndromes than older nondiabetic adults. For these conditions, special care is required in prescribing therapies including anti- diabetes drugs. Aim of this study was to evaluate the appropriateness and the adherence to safety recommendations in the prescriptions of glucose-lowering drugs in hospitalized elderly patients with diabetes. Data for this cross-sectional study were obtained from the REgistro POliterapie-Società Italiana Medicina Interna (REPOSI) that collected clinical information on patients aged ≥ 65 years acutely admitted to Italian internal medicine and geriatric non-intensive care units (ICU) from 2010 up to 2019. Prescription appropriateness was assessed according to the 2019 AGS Beers Criteria and anti-diabetes drug data sheets.Among 5349 patients, 1624 (30.3%) had diagnosis of type 2 diabetes. At admission, 37.7% of diabetic patients received treatment with metformin, 37.3% insulin therapy, 16.4% sulfonylureas, and 11.4% glinides. Surprisingly, only 3.1% of diabetic patients were treated with new classes of anti- diabetes drugs. According to prescription criteria, at admission 15.4% of patients treated with metformin and 2.6% with sulfonylureas received inappropriately these treatments. At discharge, the inappropriateness of metformin therapy decreased (10.2%, P &lt; 0.0001). According to Beers criteria, the inappropriate prescriptions of sulfonylureas raised to 29% both at admission and at discharge. This study shows a poor adherence to current guidelines on diabetes management in hospitalized elderly people with a high prevalence of inappropriate use of sulfonylureas according to the Beers criteria
