The Relation Between Domestic Violence and Professional, Contact Sports: It's Complicated.

Learning theories provide explanations for domestic violence; they can also aid in our understanding of the relation between contact sports and domestic violence. Notably, language used during sporting events and athletes' behaviors being rewarded both on and off the field can influence the behaviors of viewers. Adubato (2016) found a statistically significant relation between an increase in domestic violence arrests and the kick-off times of Philadelphia Eagles football games. Here, we replicate and extend this work to Chicago and Boston. We examine quantitative, hourly data from the Chicago and Boston Police Departments and compare mean domestic violence arrests in an 8-hour period from the average Bears' and Patriots' (football) kick-off times, respectively, to the same time period on non-football Sundays, major holidays, and days of rival Blackhawks' and Bruins' (hockey) games, respectively. Results show a significant difference in average domestic violence arrests between hockey games and non-football Sundays in Chicago only. This work highlights the importance of context in examining domestic violence nationally and has implications for domestic violence policies in professional sports' organizations.

Long-Term Acute Care Hospital Outcomes of Mechanically Ventilated Patients With Coronavirus Disease 2019.

OBJECTIVES: To describe the clinical characteristics and outcomes of adult patients with coronavirus disease 2019 requiring weaning from prolonged mechanical ventilation. DESIGN: Observational cohort study of patients admitted to two long-term acute care hospitals from April 1, 2020, to March 31, 2021. SETTING: Two long-term acute care hospitals specialized in weaning from prolonged mechanical ventilation in the Chicagoland area, Illinois, United States. PATIENTS: Adult (≥ 18 yr old) ICU survivors of respiratory failure caused by severe acute respiratory syndrome coronavirus 2 pneumonia receiving prolonged mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the study period, 158 consecutive patients were transferred to the long-term acute care hospitals for weaning from prolonged ventilation. Demographic, clinical, and laboratory data were collected and analyzed. Final date of follow-up was June 1, 2021. Prior to long-term acute care hospital transfer, median length of stay at the acute care hospital was 41.0 days and median number of ventilator days was 35. Median age was 60.0 years, 34.8% of patients were women, 91.8% had a least one comorbidity, most commonly hypertension (65.8%) and diabetes (53.2%). The percentage of weaning success was 70.9%. The median duration of successful weaning was 8 days. Mortality was 9.6%. As of June 1, 2021, 19.0% of patients had been discharged home, 70.3% had been discharged to other facilities, and 1.3% were still in the long-term acute care hospitals. CONCLUSIONS: Most patients with coronavirus disease 2019 transferred to two Chicago-area long-term acute care hospitals successfully weaned from prolonged mechanical ventilation.

Ultrasound and non-ultrasound imaging techniques in the assessment of diaphragmatic dysfunction.

Diaphragm muscle dysfunction is increasingly recognized as an important element of several diseases including neuromuscular disease, chronic obstructive pulmonary disease and diaphragm dysfunction in critically ill patients. Functional evaluation of the diaphragm is challenging. Use of volitional maneuvers to test the diaphragm can be limited by patient effort. Non-volitional tests such as those using neuromuscular stimulation are technically complex, since the muscle itself is relatively inaccessible. As such, there is a growing interest in using imaging techniques to characterize diaphragm muscle dysfunction. Selecting the appropriate imaging technique for a given clinical scenario is a critical step in the evaluation of patients suspected of having diaphragm dysfunction. In this review, we aim to present a detailed analysis of evidence for the use of ultrasound and non-ultrasound imaging techniques in the assessment of diaphragm dysfunction. We highlight the utility of the qualitative information gathered by ultrasound imaging as a means to assess integrity, excursion, thickness, and thickening of the diaphragm. In contrast, quantitative ultrasound analysis of the diaphragm is marred by inherent limitations of this technique, and we provide a detailed examination of these limitations. We evaluate non-ultrasound imaging modalities that apply static techniques (chest radiograph, computerized tomography and magnetic resonance imaging), used to assess muscle position, shape and dimension. We also evaluate non-ultrasound imaging modalities that apply dynamic imaging (fluoroscopy and dynamic magnetic resonance imaging) to assess diaphragm motion. Finally, we critically review the application of each of these techniques in the clinical setting when diaphragm dysfunction is suspected.

Current and future targeted therapies for severe asthma: Managing treatment with biologics based on phenotypes and biomarkers.

Asthma is a respiratory disorder with considerable heterogeneity in aetiology, triggers, clinical characteristics and response to therapy. This diversity reflects different inflammatory pathways that can be subdivided into clinically similar categories called phenotypes, or pathogenically comparable groups called endotypes. In recent years, a great amount of research has been dedicated to the investigation and understanding of the heterogeneity of asthma pathophysiology and to the identification of treatable traits, biomarkers, mediators and therapeutic targets. Severe asthma is defined as an uncontrolled disease despite a maximal conventional therapeutic approach. While, to date, some target therapies showing improvements in lung function, asthma symptoms and a reduction of the annual rate of exacerbations in patients with severe asthma have been already approved, other treatments are currently being studied, specifically targeting Type 2 asthma. Further progress however, is still needed to tackle the molecular pathways for non-Type 2 asthma. The aim of the present narrative review is to discuss and examine the indication, mechanisms of action and therapeutic effects of currently available and emerging biologic agents for the treatment of severe asthma.

Rationale underlying the measurement of fractional exhaled nitric oxide in systemic sclerosis patients.

Systemic sclerosis (SSc) is an autoimmune disease characterised by tissue fibrosis leading to vascular injury. Nitric oxide (NO) has been implicated in the pathogenesis of autoimmune diseases. A deficiency in basal NO production by the constitutive endothelial isoform of nitric oxide synthase may promote vasoconstriction and vascular wall thickening. In January 2017, we searched the PubMed/Medline, Cochrane Library and Enbase/Medline databases for studies analysing physio-pathological correlations with lung fractional exhaled NO (FeNO) production. This review describes the rationale underlying possible applications of FeNO measurements in the management of SSc. Measuring NO levels at multiple expiratory flow rates makes it possible to distinguish airway NO production and distal airway/alveolar NO concentration (ANOC), and there is increasing evidence indicating that it may be useful in many non-respiratory conditions. FeNO levels are increased in SSc patients with fibrosing lung disease, whereas those with pulmonary hypertension have relatively low FeNO levels, thus suggesting that NO plays an important role in regulating pulmonary vascular resistance in SSc. However, a number of studies have shown increased ANOC in SSc patients without increased FeNO levels. The relationship between lung diffusing capacity for carbon monoxide and ANOC may be related to increased alveolar membrane thickness impeding NO diffusion or alveolar inflammation in SSc lung disease. The findings concerning the usefulness of FeNO measurements in SSc patients are discordant, but the available papers suggest that ANOC is a more accurate indicator of progressive lung dysfunction and an increase in ANOC could assess the extent of interstitial lung disease non-invasively.

Fungal Keratitis: Diagnosis, Management, and Recent Advances.

Fungal keratitis is one of the major causes of microbial keratitis that may lead to corneal blindness. Many problems related to diagnosis and therapy are encountered in fungal keratitis, including difficulty in obtaining laboratory diagnoses and the availability and efficacy of antifungal medications. Intensive and prolonged use of antifungal topical preparations may not be enough. The use of antifungal medications is considered the main treatment for fungal keratitis. It is recommended to start antifungal therapy after confirmation of the clinical diagnosis with a smear or positive cultures. Topical application of antifungal medications is a mainstay for the treatment of fungal keratitis; however, systemic, intra-stromal, or intra-cameral routes may be used. Therapeutic keratoplasty is the main surgical procedure approved for the management of fungal keratitis with good success rate. Intrastromal corneal injection of antifungal medications may result in steady-state drug levels within the corneal tissue and prevent intervals of decreased antifungal drug concentration below its therapeutic level. In cases of severe fungal keratitis with deep stromal infiltration not responding to treatment, intracameral injection of antifungal agents may be effective. Collagen cross-linking has been proposed to be beneficial for cases of fungal keratitis as a stand-alone therapy or as an adjunct to antifungal medications. Although collagen cross-linking has been extensively studied in the past few years, its protocol still needs many modifications to optimize UV fluence levels, irradiation time, and concentration of riboflavin to achieve 100% microbial killing.

Anti-Inflammatory and Anti-Oxidant Properties of N-Acetylcysteine: A Fresh Perspective.

N-acetyl-L-cysteine (NAC) was initially introduced as a treatment for mucus reduction and widely used for chronic respiratory conditions associated with mucus overproduction. However, the mechanism of action for NAC extends beyond its mucolytic activity and is complex and multifaceted. Contrary to other mucoactive drugs, NAC has been found to exhibit antioxidant, anti-infective, and anti-inflammatory activity in pre-clinical and clinical reports. These properties have sparked interest in its potential for treating chronic lung diseases, including chronic obstructive pulmonary disease (COPD), bronchiectasis (BE), cystic fibrosis (CF), and idiopathic pulmonary fibrosis (IPF), which are associated with oxidative stress, increased levels of glutathione and inflammation. NAC's anti-inflammatory activity is noteworthy, and it is not solely secondary to its antioxidant capabilities. In ex vivo models of COPD exacerbation, the anti-inflammatory effects have been observed even at very low doses, especially with prolonged treatment. The mechanism involves the inhibition of the activation of NF-kB and neurokinin A production, resulting in a reduction in interleukin-6 production, a cytokine abundantly present in the sputum and breath condensate of patients with COPD and correlates with the number of exacerbations. The unique combination of mucolytic, antioxidant, anti-infective, and anti-inflammatory properties positions NAC as a safe, cost-effective, and efficacious therapy for a plethora of respiratory conditions.

Early lung diffusion abnormalities and airways' inflammation in children with type 1 diabetes.

BACKGROUND AND AIMS OF THE STUDY: Type 1 diabetes (T1D) impacts lung function and exercise capacity in adults, but limited information is available in children. We hypothesize that T1D causes alterations in pulmonary function and cardiorespiratory fitness, i.e., exercise capacity, at early stages of the disease, due to the presence of inflammation and vascular damage. Therefore, we aim to investigate pulmonary function before and after exercise in children with T1D as compared to age matched healthy controls. METHOD: Twenty-four children with T1D and twenty healthy controls underwent body plethysmography, diffusion lung capacity for carbon monoxide and fractional exhaled nitric oxide at rest and after cardio-pulmonary exercise test. RESULTS: In children with T1D, baseline total lung capacity and diffusion lung capacity for carbon monoxide were reduced as compared to healthy controls. Children with T1D also showed a reduced exercise capacity associated with poor aerobic fitness. Accordingly, diffusion lung capacity for carbon monoxide tended to increase with exercise in healthy controls, while no change was observed in children with T1D. Fractional exhaled nitric oxide was significantly higher at baseline and tended to increase with exercise in children with T1D, while no changes were observed in healthy controls. CONCLUSIONS: Altered diffusion lung capacity for carbon monoxide, increased fractional exhaled nitric oxide and a poor aerobic fitness to exercise suggests the presence of early pulmonary abnormalities in children with T1D.

Assessing the anti-collagenase activity and phytochemical evaluation of eight plants cultivated in Egypt; developing a validation method for the ellagic acid content in Chrysophyllum oliviforme using HPLC-DAD.

Preventing aging signs is a vast cosmetic quest hence; the authors felt the necessity to focus on emerging new plant extracts by the evaluation of anti-aging potential of eight plants cultivated in Egypt. Total phenolics (TPC), total flavonoids content (TFC) and collagenase assay were performed; only four plants were subjected to (ORAC) assay, ferrozine iron metal chelation assay and (HPLC) analysis against polyphenolic standard; validation method according to ICH guidelines for ellagic acid content in C. oliviforme by HPLC-DAD was performed, molecular docking simulation was implemented by (MOE) module. C. oliviforme exhibited the highest anti-collagenase with the lowest (IC50), (TPC = 299.70 ± 16.97 mg/GAE), method of validation of C. oliviforme extract following the ICH guidelines of ellagic acid content (147.446 ± 0.00041 mg/g); C. oliviforme was the most potent extract and was standardized to be reproducible for the industrial scale.

Acute dyspnea in the emergency department: a clinical review.

Acute dyspnea represents one of the most frequent symptoms leading to emergency room evaluation. Its significant prognostic value warrants a careful evaluation. The differential diagnosis of dyspnea is complex due to the lack of specificity and the loose association between its intensity and the severity of the underlying pathological condition. The initial assessment of dyspnea calls for prompt diagnostic evaluation and identification of optimal monitoring strategy and provides information useful to allocate the patient to the most appropriate setting of care. In recent years, accumulating evidence indicated that lung ultrasound, along with echocardiography, represents the first rapid and non-invasive line of assessment that accurately differentiates heart, lung or extra-pulmonary involvement in patients with dyspnea. Moreover, non-invasive respiratory support modalities such as high-flow nasal oxygen and continuous positive airway pressure have aroused major clinical interest, in light of their efficacy and practicality to treat patients with dyspnea requiring ventilatory support, without using invasive mechanical ventilation. This clinical review is focused on the pathophysiology of acute dyspnea, on its clinical presentation and evaluation, including ultrasound-based diagnostic workup, and on available non-invasive modalities of respiratory support that may be required in patients with acute dyspnea secondary or associated with respiratory failure.

Ultrasonographic Assessment of Diaphragmatic Function and Its Clinical Application in the Management of Patients with Acute Respiratory Failure.

Acute respiratory failure (ARF) is a common life-threatening medical condition, with multiple underlying etiologies. In these cases, many factors related to systemic inflammation, prolonged use of steroids, and lung mechanical abnormalities (such as hyperinflation or increased elastic recoil due to pulmonary oedema or fibrosis) may act as synergic mechanisms leading to diaphragm dysfunction. The assessment of diaphragm function with ultrasound has been increasingly investigated in the emergency department and during hospital stay as a valuable tool for providing additional anatomical and functional information in many acute respiratory diseases. The diaphragmatic ultrasound is a noninvasive and repeatable bedside tool, has no contraindications, and allows the physician to rapidly assess the presence of diaphragmatic dysfunction; this evaluation may help in estimating the need for mechanical ventilation (and the risk of weaning failure), as well as the risk of longer hospital stay and higher mortality rate. This study presents an overview of the recent evidence regarding the evaluation of diaphragmatic function with bedside ultrasound and its clinical applications, including a discussion of real-life clinical cases.

A Positive Versus Negative Interaction Memory Affects Parole Officers' Implicit Associations Between the Self-Concept and the Group Parolees.

Background: Parole officers are one of many actors in the legal system charged with interpreting and enforcing the law. Officers not only assure that parolees under their supervision comply with the terms of their release, but also monitor and control parolees' criminal behavior. They conduct their jobs through their understanding of their official mandate and make considered and deliberate choices while executing that mandate. However, their experiences as legal actors may impact their implicit cognitions about parolees. This experiment is the first of its kind to examine implicit (i.e., automatic) associations between the self and parolees among actors of the legal system. Objective: The present study examines the implicit cognitive consequences of the quality of the parole officer-parolee relationship from the perspective of the parole officer; specifically, whether parole officers who are reminded of positive experiences with parolees implicitly associate more with the group parolees than those reminded of a negative experience. In addition, we explore the moderating effects of parole officers' subjective professional orientation and identification. Method: Eighty-four New Jersey parole officers participated in the study. First, an experimental manipulation of either a past positive or negative experience was administered via a writing task. Participants then completed an Implicit Association Test (IAT) to measure associations between the self-concept of parole officers with parolees who are part of the group criminal, followed by measures of professional orientation and identification. Results: Participants who were reminded of a positive experience with a parolee exhibited stronger associations between self and the group parolee when compared to those who were reminded of a negative experience. Neither professional orientation nor parole officer group identification were related to implicit associations and did not moderate the effect of the past experience reminder on implicit associations. Conclusion and Implications: Implicit cognitions of parole officers may influence their behaviors and interactions with those whom they supervise. Positive reminders affect implicit self-associations with parolees presumably via empathy, which is known to affect the quality of therapeutic and supervision relationships; thus, theoretically, leading to improved outcomes for both officers and parolees.

Perioperative Complications and Anesthesia Practices in Managing Patients With Quadriplegia Undergoing Surgery: A Systematic Review.

Quadriplegia is associated with a multitude of health complications affecting numerous organ systems. Complications during the perioperative periods are not uncommon in this patient population due to abnormal responses to surgical stressors. Such complications include autonomic dysreflexia, cardiac ischemia, and respiratory compromise. Currently, there is no clear consensus on the ideal technique for perioperative anesthesia management in this population. In addition, the relationship between the perioperative complications and anesthesia practices have not been explored in-depth. Therefore, we aimed to investigate perioperative complications in the context of anesthesia that are associated with patients with quadriplegia undergoing various surgical procedures. Our PRISMA compliant systematic review included 12 articles covering the literature from inception to January 12, 2021. The review showed complications being pulmonary, cerebral, but most importantly and commonly cardiac in nature, with many patients suffering hypertension, and many others hypotension. In addition, our review showed that autonomic dysreflexia is common and in majority of patients, it was managed successfully with good recovery. Based on our findings, the use of anesthesia, either general or spinal, can be considered. Future studies are needed to elucidate the exact mechanisms involved in perioperative complications and anesthetic management that are associated with patients with quadriplegia. This review will aid in developing general recommendations based on the information available in the literature to guide perioperative management of this vulnerable patient population.

A reappraisal of inspiratory capacity in chronic obstructive pulmonary disease: clinical correlates and role of long-acting muscarinic antagonists and long-acting ß2 agonists.

INTRODUCTION: In patients with chronic obstructive pulmonary disease (COPD), static and dynamic hyperinflation, together with expiratory flow limitation and gas exchange abnormalities, is one of the major causes of dyspnea, decreased exercise performance and ventilatory failure. An increase in functional residual capacity (FRC) is accompanied by a decrease in inspiratory capacity (IC), which is a volume readily available, repeatable, and simple to measure with any spirometer. Changes in IC and FRC after bronchodilation, contrary to changes in FEV1, have been closely associated with improvements in dyspnea and exercise performance. We systematically searched PubMed and Embase databases for clinical trials that assessed the effects of dual bronchodilation on inspiratory capacity in patients with COPD. AREAS COVERED: Despite their pivotal role in COPD, IC and static volumes have rarely been considered as primary outcomes in randomized clinical trials assessing the efficacy of bronchodilators. Available studies on dual bronchodilation have shown a significant and persistent positive impact on IC focusing mainly on patients with moderate-to-severe COPD, whereas dynamic hyperinflation is also present at milder disease stages. EXPERT OPINION: This narrative review discusses the pathophysiological and clinical importance of measuring IC in patients with COPD and how IC can be modified by maximizing bronchodilation combining long-acting muscarinic antagonists and long-acting ß2 agonists.

The ameliorative effects of cinnamon oil against ethanol-induced gastric ulcer in rats by regulating oxidative stress and promoting angiogenesis.

Cinnamon is one of the herbal resources belonging to the Lauraceae family, is commonly used in traditional medicine and as a flavoring agent. It has antioxidant and anti-inflammatory activities. Therefore, the present study was performed to evaluate the gastroprotective effect of cinnamon on ethanol-induced gastric ulcer in comparison to omeprazole. In Wistar rats, gastric ulcers were induced using one oral dose of 70% ethanol (5 ml/kg b. w.) Cinnamon oil at doses of 2.5 ml/kg body weight and omeprazole (a reference drug) at a dose of 20 mg/kg body weight were orally administrated daily for 7 days before ulcer induction. 1 h after ethanol administration blood samples were collected and then the stomachs of sacrificed rats were subjected to biochemical, macroscopic and histological, and immunohistochemical studies. Oral administration of cinnamon oil significantly attenuated gastric ulcer as revealed by a significant increase in the gastric levels of enzymatic and non-enzymatic antioxidants namely CAT, SOD, GSH-Px, and GSH with a concomitant reduction in MDA level compared with those in the ethanol group. Pre-treatment of cinnamon oil markedly improved the level of TNF-α and PGE content. Furthermore, cinnamon oil pre-treatment significantly increased the immunoreactivity of VEGF while decreasing the immunoreactivity of COX-II. These results were further supported by histopathological findings which revealed the curing effect of cinnamon oil on the microscopic changes induced by ethanol toxicity. Cinnamon oil showed a potential gastroprotective effect on ethanol-induced gastric ulcer comparable to the gastroprotective effect of omeprazole, and its effect may be mediated through suppression of oxidative stress and gastric inflammation and promotion of angiogenesis.

Acute Improvements of Oxygenation with Cpap and Clinical Outcomes in Severe COVID-19 Pneumonia: A Multicenter, Retrospective Study.

It is not known if the degrees of improvement in oxygenation obtained by CPAP can predict clinical outcomes in patients with COVID-19 pneumonia. This was a retrospective study conducted on patients with severe COVID-19 pneumonia treated with CPAP in three University hospitals in Milan, Italy, from March 2020 to March 2021. Arterial gas analysis was obtained before and 1 h after starting CPAP. CPAP failure included either death in the respiratory units while on CPAP or the need for intubation. Two hundred and eleven patients (mean age 64 years, 74% males) were included. Baseline median PaO2, PaO2/FiO2 ratio (P/F), and the alveolar-arterial (A-a) O2 gradient were 68 (57−83) mmHg, 129 (91−179) mmHg and 310 (177−559) mmHg, respectively. Forty-two (19.9%) patients died in the respiratory units and 51 (24.2%) were intubated. After starting CPAP, PaO2/FiO2 increased by 57 (12−113; p < 0.001) mmHg, and (A-a) O2 was reduced by 68 (−25−250; p < 0.001) mmHg. A substantial overlap of PaO2, P/F, and A-a gradient at baseline and during CPAP was observed in CPAP failures and successes; CPAP-associated improvements in oxygenation in both groups were similar. In conclusion, CPAP-associated improvements in oxygenation do not predict clinical outcomes in patients with severe COVID-19 pneumonia.

Predictors of Helmet CPAP Failure in COVID-19 Pneumonia: A Prospective, Multicenter, and Observational Cohort Study.

Background: Continuous positive airway pressure (CPAP) can be beneficial in acute respiratory failure (ARF) due to coronavirus (COVID-19) pneumonia, but delaying endotracheal intubation (ETI) in nonresponders may increase mortality. We aimed at investigating the performance of composite respiratory indexes as possible predictors of CPAP failure in ARF due to COVID-19. Methods: This was a multicenter, prospective, observational, and cohort study conducted in the respiratory units of three University hospitals in Milan and in a secondary care hospital in Codogno (Italy), on consecutive adult patients with ARF due to COVID-19 pneumonia that underwent CPAP between March 2020 and March 2021. ETI transfer to the intensive care unit or death is defined CPAP failure. Predictors of CPAP failure were assessed before T0 and 1 hour after T1 CPAP initiation and included mROX index (ratio of PaO2/FiO2 to respiratory rate), alveolar-to-arterial (A-a) O2 gradient, and the HACOR (heart rate, acidosis, consciousness, oxygenation, and respiratory rate) score. Results: Three hundred and fifty four patients (mean age 64 years, 73% males) were included in the study; 136 (38.4%) satisfied criteria for CPAP failure. A-a O2 gradient, mROX, and HACOR scores were worse in patients who failed CPAP, both at T0 and T1 (p < 0.001 for all parameters). The HACOR score was associated with CPAP failure (odds ratio-OR-for every unit increase in HACOR = 1.361; 95%CI: 1.103-1.680; p=0.004; AUROC = 0.742; p < 0.001). CPAP failure was best predicted by a threshold of 4.50 (sensitivity = 53% and specificity = 87%). Conclusions: The HACOR score may be a reliable and early predictor of CPAP failure in patients treated for ARF in COVID-19 pneumonia.

Keep on tailoring CMV management in lung transplantation: 24 versus 12-month CMV hyperimmune globulins regimen effects in combined universal prophylaxis.

BACKGROUND: In lung transplantation (LTx), Cytomegalovirus (CMV) management is based on prophylaxis or pre-emptive therapy. CMV hyperimmune globulins (CMV IG) added to prophylactic antiviral agents reduce CMV manifestations and acute rejection. The length of prophylaxis regimens is variable among studies with different results. METHODS: We conduced, after demonstrating efficacy of 12 months prophylaxis on acute rejections and CMV pneumonia, a single center retrospective study comparing, during the second year after LTx, clinical effects of a long (24 months) versus short (12 months) course of combined CMV prophylaxis scheme, based on antiviral agents and CMV IG. RESULTS: We included 120 patients, 70 received a long (24 months) and 50 a short (12 months) prophylaxis. The long prophylaxis group, at 18th month, had a lower rate of neutrophilic alveolitis in BAL (63.6% vs. 94.4%, P=0.029). No other statistically significant differences were observed among the two groups of patients although we observed a reduction in both CMV (56.4% vs. 76.0% P=n.s.) and bacterial infections (23.7% vs. 32.0%, P=n.s.) during the 18th month of follow-up. We did not observe differences among two groups in acute rejection rate on transbronchial lung biopsies. CONCLUSIONS: The combined long prophylaxis course based on antiviral agents and CMV IG provides a reduction trend in CMV or bacterial infections even if not statistically significant. The significant reduction in neutrophilia in BAL compared to the cohort undergoing prophylaxis for 12 months should be carefully interpreted. An 18-month prophylaxis could be a good suggestion to be tested by other larger prospective studies.
