Randomized trial on the effects of an EMDR intervention on traumatic and obsessive symptoms during the COVID-19 quarantine: a psychometric study.

Introduction: It has been suggested that the COVID-19 pandemic was a potentially traumatic occurrence that may have induced generalized anxiety and discomfort, particularly in susceptible populations like individuals with mental illnesses. The therapeutic approach known as eye movement desensitization and reprocessing (EMDR) has been shown to be successful in helping patients process traumatic events and restore wellbeing. Nevertheless, little is known about the precise processes through which EMDR fosters symptom recovery. Methods: In order to disentangle these issues, we conducted a randomized controlled trial (ClinicalTrials.gov Identifier NCT06110702) with 107 participants who were selected from university hospitals as a sample of investigation. Random assignments were applied to the participants in order to assign them to the experimental and control groups. The experimental group, but not the control group, underwent an 8-week EMDR intervention. Body perception, disgust, and emotions of guilt and shame, as well as mental contamination and posttraumatic and obsessive-compulsive symptoms, were investigated before and after the EMDR intervention. Results: The EMDR intervention was able to improve all of the variables investigated. Path analysis showed that body perception was able to predict both disgust and emotions of guilt and shame. Disgust was able to predict both mental contamination and obsessive-compulsive symptoms, while guilt and shame were able to predict post-traumatic symptoms. Conclusions: EMDR is an effective therapy for the treatment of post-traumatic and obsessive symptoms that acts through the promotion of improvement of the emotions of guilt/shame and disgust, respectively. Implications for clinical practice are examined. Clinical trial registration: https://www.clinicaltrials.gov, identifier NCT06110702.

REDISCOVER guidelines for borderline-resectable and locally advanced pancreatic cancer: management algorithm, unanswered questions, and future perspectives.

The REDISCOVER guidelines present 34 recommendations for the selection and perioperative care of borderline-resectable (BR-PDAC) and locally advanced ductal adenocarcinoma of the pancreas (LA-PDAC). These guidelines represent a significant shift from previous approaches, prioritizing tumor biology over anatomical features as the primary indication for resection. Condensed herein, they provide a practical management algorithm for clinical practice. However, the guidelines also highlight the need to redefine LA-PDAC to align with modern treatment strategies and to solve some contradictions within the current definition, such as grouping "difficult" and "impossible" to resect tumors together. Furthermore, the REDISCOVER guidelines highlight several areas requiring urgent research. These include the resection of the superior mesenteric artery, the management strategies for patients with LA-PDAC who are fit for surgery but unable to receive multi-agent neoadjuvant chemotherapy, the approach to patients with LA-PDAC who are fit for surgery but demonstrate high serum Ca 19.9 levels even after neoadjuvant treatment, and the optimal timing and number of chemotherapy cycles prior to surgery. Additionally, the role of primary chemoradiotherapy versus chemotherapy alone in LA-PDAC, the timing of surgical resection post-neoadjuvant/primary chemoradiotherapy, the efficacy of ablation therapies, and the management of oligometastasis in patients with LA-PDAC warrant investigation. Given the limited evidence for many issues, refining existing management strategies is imperative. The establishment of the REDISCOVER registry ( https://rediscover.unipi.it/ ) offers promise of a unified research platform to advance understanding and improve the management of BR-PDAC and LA-PDAC.

Validation of the Italian version of the Neuroception of Psychological Safety Scale (NPSS).

Research on the neuroscience of fear in both humans and non-humans has suggested that a lack of acquisition of safety cues might be a biological hallmark of posttraumatic stress disorder (PTSD). Danger perception, and in particular, feeling as one's own life is in danger, is thought to represent a major predictor of PTSD. Persistent danger perception is concurrently associated with a persistence of lack of safety. However, despite several research efforts, no validated psychometric tools exist regarding psychological safety as a unique core construct in the domain of a soothing-contentment system. By including social, compassionate, and bodily components, the Neuroception of Psychological Safety Scale (NPSS), neurophysiologically rooted in the polyvagal theory, aims to specifically assess psychological safety. Originally developed in English, we employed a rather large non clinical sample to validate our Italian translation of the NPSS (n = 338) and the scale was found to retain a three-factor structure. In light of its positive moderate correlations with the Unconditional Self-Kindness Scale (ρ = 0.376) and the Self-Compassion Scale-Short-Form (ρ = 0.481), good convergent validity and robust psychometric properties were shown by the NPSS. The Subjective Traumatic Outlook Questionnaire (ρ = -0.283) and the three subscales of the Body Perception Questionnaire-22-Body Awareness (ρ = -0.103), Supradiaphragmatic Reactivity (ρ = -0.234), and Body Awareness/Subdiaphragmatic Reactivity (ρ = -0.146)-were found to have weak negative correlations with the NPSS, which further demonstrated its good discriminant validity. Eventually, the NPSS was found to show good test-retest reliability (intraclass correlation coefficient = 0.922; three-week time interval), and its usage is fostered in clinical and research contexts where the evaluation of psychological safety is of relevance.

REDISCOVER International Guidelines on the Perioperative Care of Surgical Patients With Borderline-resectable and Locally Advanced Pancreatic Cancer.

OBJECTIVE: The REDISCOVER consensus conference aimed at developing and validating guidelines on the perioperative care of patients with borderline-resectable (BR-) and locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: Coupled with improvements in chemotherapy and radiation, the contemporary approach to pancreatic surgery supports the resection of BR-PDAC and, to a lesser extent, LA-PDAC. Guidelines outlining the selection and perioperative care for these patients are lacking. METHODS: The Scottish Intercollegiate Guidelines Network (SIGN) methodology was used to develop the REDISCOVER guidelines and create recommendations. The Delphi approach was used to reach a consensus (agreement ≥80%) among experts. Recommendations were approved after a debate and vote among international experts in pancreatic surgery and pancreatic cancer management. A Validation Committee used the AGREE II-GRS tool to assess the methodological quality of the guidelines. Moreover, an independent multidisciplinary advisory group revised the statements to ensure adherence to nonsurgical guidelines. RESULTS: Overall, 34 recommendations were created targeting centralization, training, staging, patient selection for surgery, possibility of surgery in uncommon scenarios, timing of surgery, avoidance of vascular reconstruction, details of vascular resection/reconstruction, arterial divestment, frozen section histology of perivascular tissue, extent of lymphadenectomy, anticoagulation prophylaxis, and role of minimally invasive surgery. The level of evidence was however low for 29 of 34 clinical questions. Participants agreed that the most conducive means to promptly advance our understanding in this field is to establish an international registry addressing this patient population ( https://rediscover.unipi.it/ ). CONCLUSIONS: The REDISCOVER guidelines provide clinical recommendations pertaining to pancreatectomy with vascular resection for patients with BR-PDAC and LA-PDAC, and serve as the basis of a new international registry for this patient population.

Fish Intake in Relation to Fatal and Non-Fatal Cardiovascular Risk: A Systematic Review and Meta-Analysis of Cohort Studies.

Epidemiological studies have shown that eating fish significantly reduces cardiovascular disease (CVD) incidence and mortality. However, more focused meta-analyses based on the most recent results from prospective cohort studies are needed. This systematic review and meta-analysis aims to update the association between fish intake and cardiovascular disease (CVD) risk using recent prospective studies. A systematic review and meta-analysis following the PRISMA guideline was conducted based on a random effects synthesis of multivariable-adjusted relative risks (RRs) of high vs. low categories of fish intake in relation to CVD incidence and mortality. Non-linear meta-regression was applied to investigate the shape of the association between fish intake and CVD risk. Sensitivity analysis and stratifications by type of CVD outcome, type of fish intake and type of cooking were performed. Based on 18 papers reporting 17 independent estimates of CVD risk (1,442,407 participants and 78,805 fatal and non-fatal CVD events), high vs. low intake of fish corresponded to about 8% reduced CVD risk (RR = 0.93 [0.88-0.98]). According to a non-linear dose-response meta-regression, 50 g of fish intake per day corresponded to a statistically significant 9% reduced fatal and non-fatal CVD risk (RR = 0.92 [0.90-0.95]). Similarly, fish intake in the range of a weekly intake of two to three portions of fish with a size of 150 g resulted in 8% fatal and non-fatal CVD risk reduction (RR = 0.93 [0.91-0.96]). The recommended two portions of fish a week reduces the risk of CVD outcomes by approximately 10%. A full portion of fish a day reduces CVD risk by up to 30%.

Increasing incidence and prevalence of metabolic syndrome in people living with HIV during the COVID-19 pandemic.

Introduction: The aim of this study was to analyze the impact of COVID-19 pandemic restrictions on the prevalence and incidence of metabolic syndrome (MS), and to identify predictors of new MS cases in people living with HIV (PLWH). Methods: This cohort study included PLWH followed at the IRCCS San Raffaele, Milan, Italy, with at least one body mass index (BMI) determination during the pre-pandemic period (1 December 2018 to 29 February 2020) and the pandemic period (1 March 2020 to 31 May 2021). MS diagnosis was based on NCEP ATP III 2005 criteria. Univariable Poisson regression model was used to compare MS incidence rates. Univariable mixed linear models estimated the crude mean change in metabolic parameters during each time period. Multivariable Cox proportional hazards model was used to assess risk factors for MS. Results: This study included 1,564 PLWH, of whom 460 and 1,104 were with and without a diagnosis of MS, respectively, at the beginning of the pre-pandemic period, with an overall prevalence of MS of 29.4%. During the pre-pandemic period, 528/1,564 PLWH had MS, with a prevalence of 33.8% (95%CI = 31.5%-36.1%), while during the pandemic period, the number of PLWH with a diagnosis of MS increased to 628/1,564, with a prevalence of 40.2% (95%CI 37.8%-42.6%; McNemar's test: p < 0.0001). Similarly, the MS incidence rate increased from 13.7/100 person-years of follow-up (PYFU; 95%CI = 11.7-16.0) in the pre-pandemic period to 18.5/100 PYFU (95%CI = 16.2-21.1) in the pandemic period (p = 0.004), with 201 subjects developing MS during the pandemic period. In addition, we observed a significant increase in the crude mean change during the pandemic period compared with the pre-pandemic period for: total cholesterol, LDL cholesterol, plasma glucose, blood pressure, and atherosclerotic cardiovascular disease (ASCVD) risk score. Finally, after adjustment for HIV risk factors, HBV, HCV, ART duration, duration of virologic suppression and use of INSTIs, age [adjusted hazard ratio (AHR) per 3 years older = 1.12 (95%CI = 1.08-1.17)], sex [AHR female vs. male = 0.62 (95%CI = 0.44-0.87)] and CD4+ cell count [AHR per 100 cells/µL higher = 1.05 (95%CI = 1.01-1.09)] were associated with the risk of MS. Conclusion: The COVID-19 pandemic affected the metabolic profile of PLWH and increased the prevalence and incidence of MS.

The integrative process promoted by EMDR in dissociative disorders: neurobiological mechanisms, psychometric tools, and intervention efficacy on the psychological impact of the COVID-19 pandemic.

Dissociative disorders (DDs) are characterized by a discontinuity in the normal integration of consciousness, memory, identity, emotion, perception, bodily representation, motor control, and action. The life-threatening coronavirus disease 2019 (COVID-19) pandemic has been identified as a potentially traumatic event and may produce a wide range of mental health problems, such as depression, anxiety disorders, sleep disorders, and DD, stemming from pandemic-related events, such as sickness, isolation, losing loved ones, and fear for one's life. In our conceptual analysis, we introduce the contribution of the structural dissociation of personality (SDP) theory and polyvagal theory to the conceptualization of the COVID-19 pandemic-triggered DD and the importance of assessing perceived safety in DD through neurophysiologically informed psychometric tools. In addition, we analyzed the contribution of eye movement desensitization and reprocessing (EMDR) to the treatment of the COVID-19 pandemic-triggered DD and suggest possible neurobiological mechanisms of action of the EMDR. In particular, we propose that, through slow eye movements, the EMDR may promote an initial non-rapid-eye-movement sleep stage 1-like activity, a subsequent access to a slow-wave sleep activity, and an oxytocinergic neurotransmission that, in turn, may foster the functional coupling between paraventricular nucleus and both sympathetic and parasympathetic cardioinhibitory nuclei. Neurophysiologically informed psychometric tools for safety evaluation in DDs are discussed. Furthermore, clinical and public health implications are considered, combining the EMDR, SDP theory, and polyvagal conceptualizations in light of the potential dissociative symptomatology triggered by the COVID-19 pandemic.

Engineered Tissue Graft for Repair of Injured Infraspinatus Rotator Cuff Tendon.

Rotator cuff tears constitute a vast majority of shoulder-related injuries, occurring in a wide population range and increasing in incidence with age. Current treatments for full thickness tears use suture to secure the ruptured tendon back to its native attachment site and often retear due to improper enthesis regeneration. To reduce the occurrence of retear, our laboratory developed an engineered tendon graft for rotator cuff repair (ETG-RC) to serve as an underlayment to traditional suture repair. We hypothesize the ETG-RC will aid in the repair of the torn rotator cuff tendon by promoting the regeneration of a functional enthesis. This devitalized graft fabricated from ovine-derived bone marrow stromal cells was evaluated for biomechanical and histomorphology properties in an ovine infraspinatus rotator cuff repair model. Compared with a current standard practice Suture-Only model, the ETG-RC repair showed comparable high strain-to-failure forces, greater fibrocartilage deposition, regeneration of zonal gradients, and Shapey's fibers formation, indicative of enthesis regeneration. Enthesis regeneration after rotator cuff repair should repair mechanical properties and alleviate the need for subsequent surgeries required due to retear. The ETG-RC could potentially be used for repairing other tendon injuries throughout the body.

Treatment success of rescue regimens after dual therapy failure in people living with HIV in a real-life setting.

OBJECTIVES: Few data on management of two-drug regimen (2DR) failure in people living with HIV (PLWH) are available. METHODS: Retrospective study of treatment-experienced PLWH on a 2DR who experienced virological failure (VF) [two consecutive viral loads (VLs) ≥50 copies/mL, single VL ≥1000 copies/mL, or antiretroviral therapy (ART) switch after single VL ≥50 copies/mL with previous blips] or discontinuation for toxicity (baseline). Integrase strand transfer inhibitor (INSTI)-based [one INSTI plus one nucleoside reverse transcriptase inhibitor (NRTI) (n = 78) or one non-NRTI (n = 20)] or boosted protease inhibitor (PI/b)-based [one PI/b plus one NRTI (n = 116) or one INSTI (n = 12)] 2DRs were included. Probabilities of treatment success (TS), VF and discontinuation for any other cause of rescue regimens were estimated by Kaplan-Meier curves. A stepwise Cox model was performed to assess predictors of TS. RESULTS: Overall, 226 PLWH were evaluated: at baseline, 144 individuals discontinued 2DR for toxicity and 82 had VF [median viraemia 81 (63-212) copies/mL]; 171 switched therapy (49.7% to triple regimen, 40.9% to different 2DR), while 55 (exclusively with VF) maintained failing regimens. Probabilities of 12- and 24-month TS were 75.6% and 64.7%, respectively. Higher TS probabilities were observed in individuals who switched ART at 2DR failure (P = 0.003) and PLWH who discontinued 2DR for toxicity (P = 0.008). Therapy switch was the only predictor of TS (P = 0.002). CONCLUSIONS: Overall probability of rescue regimens' TS introduced after 2DR failure is good. Prompt ART switch after 2DR failure is advisable.

Validation and Psychometric Properties of the Italian Version of the Unconditional Self-Kindness Scale (USKS).

Western psychology and social sciences have long emphasized the value of a positive attitude toward oneself. Previous research had developed psychometric tools assessing self-compassion, defined as being open to and moved by one's own suffering. However, self-compassion did not describe whether people actually applied such protective factors when acutely faced with threats. The Unconditional Self-Kindness Scale (USKS) was developed as a tool to measure the behavioral response of self-kindness during an acute presence of threat to the self and not just as a general attitude when threat is absent. Since it can be experienced even in the most challenging situations and may promote resilience, this kindness may be defined as unconditional. We validated the Italian version of the USKS and found that the scale retained a one-factor structure. The USKS showed sound psychometric properties and good convergent validity since it was found to show very strong correlations with the Self-Compassion Scale-Short-Form and the Reassure Self subscale of the Forms of Self-criticizing/Attacking and Self-Reassuring Scale (FSCRS). In addition, the USKS showed good discriminant validity since it was found to show a negative moderate correlation and a negative strong correlation with the HS subscale and with the IS subscale of the FSCRS, respectively. Finally, the USKS showed good test-retest reliability and its use is encouraged in clinical and research settings in which the assessment of a positive attitude toward oneself during an acute presence of threat to the self is of interest.

Selective Disruption of Perineuronal Nets in Mice Lacking Crtl1 is Sufficient to Make Fear Memories Susceptible to Erasure.

The ability to store, retrieve, and extinguish memories of adverse experiences is an essential skill for animals' survival. The cellular and molecular factors that underlie such processes are only partially known. Using chondroitinase ABC treatment targeting chondroitin sulfate proteoglycans (CSPGs), previous studies showed that the maturation of the extracellular matrix makes fear memory resistant to deletion. Mice lacking the cartilage link protein Crtl1 (Crtl1-KO mice) display normal CSPG levels but impaired CSPG condensation in perineuronal nets (PNNs). Thus, we asked whether the presence of PNNs in the adult brain is responsible for the appearance of persistent fear memories by investigating fear extinction in Crtl1-KO mice. We found that mutant mice displayed fear memory erasure after an extinction protocol as revealed by analysis of freezing and pupil dynamics. Fear memory erasure did not depend on passive loss of retention; moreover, we demonstrated that, after extinction training, conditioned Crtl1-KO mice display no neural activation in the amygdala (Zif268 staining) in comparison to control animals. Taken together, our findings suggest that the aggregation of CSPGs into PNNs regulates the boundaries of the critical period for fear extinction.

Evaluation of HIV-DNA and residual viremia levels through week 96 in HIV-infected individuals who continue a two-drug or switch to a three-drug integrase strand transfer inhibitor-based regimen.

OBJECTIVES: To investigate HIV-DNA and residual viremia (RV) levels over 96 weeks (W96) in virologically-suppressed HIV-1-infected individuals enrolled in the Be-OnE Study. Individuals were randomised to continue a two-drug regimen with dolutegravir (DTG) plus one reverse transcriptase inhibitor (RTI) or to switch to elvitegravir/cobicistat/emtricitabine/tenofovir-alafenamide (E/C/F/TAF). STUDY DESIGN: Total HIV-DNA and RV were evaluated at baseline, W48 and W96 using droplet digital polymerase chain reaction (ddPCR) technique. Potential relationships between viro-immunological parameters and between/within arms were also assessed. RESULTS: Median (interquartile range [IQR]) HIV-DNA was 2247 (767-4268), 1587 (556-3543) and 1076 (512-2345) copies/106 CD4+T-cells at baseline, W48 and at W96, respectively; RV was 3 (1-5), 4 (1-9) and 2 (2-4) copies/mL, respectively, with no significant differences between arms. A significant reduction in HIV-DNA and RV from baseline to W96 was observed in the E/C/F/TAF arm (HIV-DNA: -285 [-2257; -45], P=0.010; RV: -1 [-3;0], P=0.007). In the DTG + 1 RTI arm, HIV-DNA and RV levels remained stable (HIV-DNA: -549 [-2269;+307], P=0.182; RV: -1 [-3;+1], P=0.280). For both HIV-DNA and RV, there were no significant changes over time between the arms. A positive correlation was found between baseline HIV-DNA and HIV-DNA at W96 (E/C/F/TAF: Spearman correlation coefficient (rs)=0.726, P=0.0004; DTG + 1 RTI: rs=0.589, P=0.010). In general, no significant correlations were found between HIV-DNA, RV and immunological parameters over time. CONCLUSIONS: In virologically-suppressed individuals, there was a small reduction in HIV-DNA and HIV-RNA levels from baseline to W96 in individuals who switched to the E/C/F/TAF arm compared with those who remained on DTG + 1 RTI. However, there were no significant differences between the two arms in the changes in HIV-DNA and HIV-RNA over time.

Inflammation burden score in multidrug-resistant HIV-1 infection.

OBJECTIVES: Four-class drug-resistant (4DR) people living with HIV (PLWH) are a fragile population with a high burden of disease. No data on their inflammation and T-cell exhaustion markers are currently available. METHODS: Inflammation, immune activation and microbial translocation biomarkers were measured through ELISA in 30 4DR-PLWH with HIV-1 RNA ≥ 50 copies/mL, 30 non-viremic 4DR-PLWH and 20 non-viremic non-4DR-PLWH. Groups were matched by age, gender and smoking habit. T-cell activation and exhaustion markers were assessed by flow cytometry in 4DR-PLWH. An inflammation burden score (IBS) was calculated from soluble marker levels and associated factors were estimated through multivariate regression. RESULTS: The highest plasma biomarker concentrations were observed in viremic 4DR-PLWH, the lowest ones in non-4DR-PLWH. Endotoxin core immunoglobulin G showed an opposite trend. Among 4DR-PLWH, CD38/HLA-DR and PD-1 were more expressed on CD4+ (p = 0.019 and 0.034, respectively) and CD8+ (p = 0.002 and 0.032, respectively) cells of viremic compared to non-viremic subjects. An increased IBS was significantly associated with 4DR condition, higher values of viral load and a previous cancer diagnosis. CONCLUSIONS: Multidrug-resistant HIV infection is associated with a higher IBS, even when viremia is undetectable. Therapeutic approaches aimed to reduce inflammation and T-cell exhaustion in 4DR-PLWH need to be investigated.

Dietary Fatty Acids and Inflammation: Focus on the n-6 Series.

Among the polyunsaturated fatty acids (PUFAs), those belonging to the n-3 (or ω3) series, i.e., alpha-linolenic (ALA), eicosapentaenoic (EPA), and docosahexaenoic (DHA) acids have been studied for decades from a pharma-nutritional viewpoint, namely in relation to cardiovascular health. More recent research is focusing on n-6 PUFAs, e.g., linoleic acid (LA), whose levels of consumption are much higher than those of n-3 and that cannot be used "pharmacologically". Perhaps because of this, the biological actions of n-6 PUFAs have not been investigated in details as those of their n-3 counterparts. However, an increasing body of evidence underscores their healthful actions on the cardiovascular system. Among the critiques to n-6 PUFAs and, particularly, LA there is the fact that they are precursors of pro-inflammatory eicosanoids. Hence, the hypothesis posits that we should reduce their intakes precisely to avoid increasing systemic, low-grade inflammation, i.e., one of the major etiological agents in degenerative diseases. In this narrative review, we address the issue of whether n-6 PUFAs are indeed pro-inflammatory, we discuss the most recent evidence of their role(s) in human health and prognosis, and we conclude that adequate intakes of n-6 fatty acids are associated with better cardiovascular health and child development.

Role of Portion Size in the Context of a Healthy, Balanced Diet: A Case Study of European Countries.

Over the past decades, a generalised increase in food portion sizes has probably contributed to the growing global obesity epidemic. Increasing awareness of appropriate portion sizes could contribute to reversing this trend through better control of calorie intake. In this study, a comparison of standard portion sizes in European countries for various food categories shows a wide variability of their importance for food, nutrient, and energy consumption according to government and institutional websites. On the other hand, the overall averages appear to be largely in line with the values indicated by the Italian Society of Human Nutrition, which is the most comprehensive and detailed document among those evaluated. The exceptions are milk and yoghurt, for which the reference portions in Europe are generally higher, and vegetables and legumes, for which portions are smaller than those reported in the Italian document. Moreover, the portion sizes of staple foods (e.g., pasta and potatoes) vary according to different food traditions. It is reasonable to consider that the creation of harmonised standard reference portions common to the European countries, based on international guidelines and scientific evidence, would significantly contribute to consumers' nutritional education and ability to make informed choices for a healthy diet.

Antibiotic appropriateness for Gram-negative bloodstream infections: impact of infectious disease consultation.

BACKGROUND: We investigated the role of infectious disease consultation (IDC) on therapeutic appropriateness in Gram-negative bloodstream infections (GNBSIs) in a setting with a high proportion of antibiotic resistance. Secondary outcomes were in-hospital mortality and the impact of rapid diagnostic tests (RDTs). METHODS: Retrospective study on hospitalised patients with GNBSIs. Therapy was deemed appropriate if it had the narrowest spectrum considering infection and patients' characteristics. Interventional-IDC (I-IDC) group included patients with IDC-advised first appropriate or last non-appropriate therapy. Time to first appropriate therapy and survival were evaluated by Kaplan-Meier curves. Factors associated with therapy appropriateness were assessed by multivariate Cox proportional-hazard models. RESULTS: 471 patients were included. High antibiotic resistance rates were detected: quinolones 45.5%, third-generation cephalosporins 37.4%, carbapenems 7.9%. I-IDC was performed in 31.6% of patients (149/471), RDTs in 70.7% (333/471). The 7-day probability of appropriate treatment was 91.9% (95% confidence interval [95%CI]: 86.4-95.8%) vs. 75.8% (95%CI: 70.9-80.4%) with and without I-IDC, respectively (p-value = 0.0495); 85.5% (95%CI: 81.3-89.1%) vs. 69.4% (95%CI: 61.3-77.2%) with and without RDTs, respectively (p-value = 0.0023). Compared to RDTs alone, the combination with I-IDC was associated with a higher proportion of appropriate therapies at day 7: 81.9% (95%CI: 76.4-86.7%) vs. 92.6% (95%CI: 86.3-96.7%). At multivariate analysis, I-IDC and RDTs were associated with time to first appropriate therapy [adjusted hazard-ratio 1.292 (95%CI: 1.014-1.647) and 1.383 (95%CI: 1.080-1.771), respectively], with no impact on mortality. CONCLUSIONS: In a setting with a high proportion of antibiotic resistance, IDC and RDTs were associated with earlier prescription of appropriate therapy in GNBSIs, without impact on mortality.

Non-Union Scoring System (NUSS): Is It Enough in Clinical Practice?

Introduction: Bone consolidation defects represent a real orthopedic challenge because of the absence of validated treatment guidelines that can assist the surgeon in his choices. The aim of this study is to evaluate the appropriateness of the Non-Union Scoring System NUSS treatment protocol in the management of long bone non-unions by comparing it to the experience-based therapeutic approach carried out in our facility. Materials and Methods: We conducted a comparative outcome study of a retrospective series of 89 patients surgically treated for long bone non-union in our facility vs. clinical results reported by Calori et al. obtained following the NUSS treatment protocol. Results: Radiographic healing was reached in 13/13 non-unions (100%) in group NUSS 1, in 58/62 (93.5%) in group NUSS 2, and in 13/14 (92.9%) in group NUSS 3. The mean time to radiographic healing was 5.69 ± 2.09 months in group 1, 7.38 ± 3.81 months in group 2 and 9.23 ± 2.31 months in group 3. 91% of patients in group I, 69% in group II and 48% in group III received what would be considered by the NUSS treatment protocol an "overtreatment", especially from a biological stand point. The comparative outcome analysis shows that our case series achieved significantly higher global healing rates (p value = 0.017) and shorter radiological healing times in groups NUSS 1 and 2 (p value < 0.001). Conclusion: From the results obtained, we can assume that the NUSS treatment protocol might underestimate the necessary therapies, particularly from a biological point of view.

LDL-cholesterol control in the primary prevention of cardiovascular diseases: An expert opinion for clinicians and health professionals.

AIMS: Although adequate clinical management of patients with hypercholesterolemia without a history of known cardiovascular disease is essential for prevention, these subjects are often disregarded. Furthermore, the scientific literature on primary cardiovascular prevention is not as rich as that on secondary prevention; finally, physicians often lack adequate tools for the effective management of subjects in primary prevention and have to face some unsolved relevant issues. This document aims to discuss and review the evidence available on this topic and provide practical guidance. DATA SYNTHESIS: Available algorithms and risk charts represent the main tool for the assessment of cardiovascular risk in patients in primary prevention. The accuracy of such an estimate can be substantially improved considering the potential contribution of some additional risk factors (C-reactive protein, lipoprotein(a), family history of cardiovascular disease) and conditions (environmental pollution, sleep quality, socioeconomic status, educational level) whose impact on the cardiovascular risk has been better understood in recent years. The availability of non-invasive procedures to evaluate subclinical atherosclerosis may help to identify subjects needing an earlier intervention. Unveiling the presence of these conditions will improve cardiovascular risk estimation, granting a more appropriate intervention. CONCLUSIONS: The accurate assessment of cardiovascular risk in subjects in primary prevention with the use of algorithms and risk charts together with the evaluation of additional factors will allow physicians to approach each patient with personalized strategies, which should translate into an increased adherence to therapy and, as a consequence, a reduced cardiovascular risk.
