Abstract
We investigated the role of Coefficient of Variation (CoV), a first-order texture parameter derived from 18F-FDG PET/CT, in the prognosis of Non-Small Cell Lung Cancer (NSCLC) patients. Eighty-four patients with advanced NSCLC who underwent 18F-FDG PET/CT before therapy were retrospectively studied. SUVmax, SUVmean, CoV, total Metabolic Tumor Volume (MTVTOT) and whole-body Total Lesion Glycolysis (TLGWB) were determined by an automated contouring program (SUV threshold at 2.5). We analyzed 194 lesions: primary tumors (n = 84), regional (n = 48) and non-regional (n = 17) lymph nodes and metastases in liver (n = 9), bone (n = 23) and other sites (n = 13); average CoVs were 0.36 ± 0.13, 0.36 ± 0.14, 0.42 ± 0.18, 0.30 ± 0.14, 0.37 ± 0.17, 0.34 ± 0.13, respectively. No significant differences were found between the CoV values among the different lesion categories. Survival analysis included age, gender, histology, stage, MTVTOT, TLGWB and imaging parameters derived from primary tumors. At univariate analysis, CoV (p = 0.0184), MTVTOT (p = 0.0050), TLGWB (p = 0.0108) and stage (p = 0.0041) predicted Overall Survival (OS). At multivariate analysis, age, CoV, MTVTOT and stage were retained in the model (p = 0.0001). Patients with CoV > 0.38 had significantly better OS than those with CoV ≤ 0.38 (p = 0.0143). Patients with MTVTOT ≤ 89.5 mL had higher OS than those with MTVTOT > 89.5 mL (p = 0.0063). Combining CoV and MTVTOT, patients with CoV ≤ 0.38 and MTVTOT > 89.5 mL had the worst prognosis. CoV, by reflecting the heterogeneity of glycolytic phenotype, can predict clinical outcomes in NSCLC patients.

Abstract
BACKGROUND Advances in treatment and optimization of chemotherapy protocols have greatly improved survival in cancer patients. Unfortunately, treatment can cause a reduction in left ventricular (LV) ejection fraction (EF) leading to cancer therapy-related cardiac dysfunction (CTRCD). We conducted a scoping review of published literature in order to identify and summarize the reported prevalence of cardiotoxicity evaluated by noninvasive imaging procedures in a wide-ranging of patients referred to cancer treatment as chemotherapy and/or radiation therapy. METHODS Different databases were checked (PubMed, Embase, and Web of Science) to identify studies published from January 2000 to June 2021. Articles were included if they reported data on LVEF evaluation in oncological patients treated with chemotherapeutic agents and/or radiotherapy, measured by echocardiography and/or nuclear or cardiac magnetic resonance imaging test, providing criteria of CTRCD evaluation such as the specific threshold for LVEF decrease. RESULTS From 963 citations identified, 46 articles, comprising 6841 patients, met the criteria for the inclusion in the scoping review. The summary prevalence of CTRCD as assessed by imaging procedures in the studies reviewed was 17% (95% confidence interval, 14-20). CONCLUSIONS The results of our scoping review endorse the recommendations regarding imaging modalities to ensure identification of cardiotoxicity in patients undergoing cancer therapies. However, to improve patient management, more homogeneous CTRCD evaluation studies are required, reporting a detailed clinical assessment of the patient before, during and after treatment.

Abstract
PURPOSE We assessed the impact of COVID-19 infection on cardiovascular events in patients with suspected or known coronary artery disease (CAD) referred to stress single-photon emission computed tomography myocardial perfusion imaging (MPS). METHODS A total of 960 consecutive patients with suspected or known CAD were submitted by referring physicians to stress MPS for assessment of myocardial ischemia between January 2018 and June 2019. All patients underwent stress-optional rest MPS. Perfusion defects were quantitated as % of LV myocardium and expressed as total perfusion defect (TPD), representing the defect extent and severity. A TPD ≥ 5% was considered abnormal. RESULTS During a mean follow-up of 27 months (range 4-38) 31 events occurred. Moreover, 55 (6%) patients had a COVID-19 infection. The median time from index MPS to COVID-19 infection was 16 months (range 6-24). At Cox multivariable analysis, abnormal MPS and COVID-19 infection resulted as independent predictors of events. There were no significant differences in annualized event rate in COVID-19 patients with or without abnormal MPS (p = 0.56). Differently, in patients without COVID-19, the presence of abnormal MPS was associated with higher event rate (p < .001). Patients with infection compared to those without had a higher event rate in the presence of both normal and abnormal TPD. CONCLUSION In patients with suspected or known CAD, the presence of COVID-19 infection during a short-term follow-up was associated with a higher rate of cardiovascular events.

Abstract
Purpose
The Covid-19 pandemic has placed health-care systems and their facilities throughout the world under immense pressure. The pandemic has highlighted the crucial role of health-care facilities design in looking beyond the ongoing crisis and considering how hospitals can better prepare for unexpected future health situations. This study aims to investigate how hospitals reacted to the crisis in terms of their physical spaces, which architectural features permitted the necessary transformations, and how this data can inform hospital design research in the future.
Design/methodology/approach
The research adopted a qualitative and multi-method approach to case studies. Data was collected directly (field survey and interviews) and indirectly (literature, periodicals, specialised websites, webinars, conferences and forums), and a strengths, weaknesses, opportunities, threats analysis supported the data evaluation.
Findings
Hospitals’ responses to the crisis were guided by a host of variables depending on the specific intervention context and risk scenario. Some key issues emerged as particularly meaningful to drive future research in hospital design, namely, architectural typology, layout and spatial proximities, technological systems, the quality of care spaces, the role of public spaces, facility management tools to drive the transformation, territorial health care networks and new technologies.
Originality/value
The paper suggests that the current crisis can be transformed into an opportunity, in terms of research and innovation, to rethink and improve the quality and efficiency of health-care spaces, restoring their crucial role of promoting health by design.

Abstract
OBJECTIVES The aim of this study is to assess the levels and diagnostic accuracy of a set of bone resorption biomarkers, including TRAP-5, RANKL, and OPG in symptomatic and asymptomatic apical lesions and controls. MATERIALS AND METHODS Apical tissues from symptomatic and asymptomatic apical periodontitis patients and periodontal ligaments from healthy teeth extracted for orthodontic reasons were processed for tissue homogenization and the levels of TRAP-5, RANKL, and OPG were determined by multiplex assay. Marker levels were analyzed by Kruskal Wallis test, and diagnostic accuracy was analyzed with ROC curves. RESULTS Higher levels of RANKL, OPG, and RANKL/OPG ratio were determined in both types of apical lesions compared to healthy periodontal ligament, whereas higher TRAP-5 levels were found only in symptomatic apical lesions (p < 0.05). OPG, RANKL, and RANKL/OPG ratio showed diagnostic potential to identify apical lesions versus healthy controls (AUC = 0.69, p < 0.05); while TRAP-5 showed a potential to discriminate symptomatic versus asymptomatic apical periodontitis (AUC = 0.71, p < 0.05) and healthy controls (AUC = 0.83, p < 0.05). CONCLUSIONS Apical lesions showed higher RANKL and OPG levels than healthy tissues. TRAP-5 levels were the highest in symptomatic apical lesions, suggesting that these represent a progressive state, and showed diagnostic potential. CLINICAL RELEVANCE Clinically symptomatic apical periodontitis might represent biologically progressive apical lesions based on TRAP5 levels. TRAP5 has diagnostic potential to identify these lesions, representing a candidate prognostic biomarker.

Abstract
The lack of updated neonatal reference values for hematological parameters impacts significantly with clinical management of both healthy and sick newborns. The present pilot study was thus aimed at assessing updated hematological Italian reference values in late preterm and term newborns. From January 2004 to December 2008 hematological laboratory tests were performed in 1175 newborns (820 healthy and 355 sick controls) between 33-41 weeks of gestation, during the first four days after birth. Hematological parameters were sorted for gender and gestational age and statistically analyzed. No gender-related differences were observed at different weeks of gestation and no significant differences were found when study population was sub-grouped for late preterm and term newborns. During the first 4 days of life erythrocytes and platelets remained stable whilst white blood cell counts and differentials were significantly modified. This study shares updated reference values for hematological parameters in the early phases after birth and offers additional support for improving the management of sick infants.

Abstract
BACKGROUND The literature on the involvement of mannose-binding lectin (MBL) in human immunodeficiency virus (HIV) transmission and acquired immunodeficiency syndrome (AIDS) is conflicting. Polymorphisms in the MBL2 gene reduce the level of protein and alter its structure. Thus, we investigated whether MBL2 alleles and plasma concentrations of MBL are associated with perinatal HIV transmission and disease progression. METHODS Frequencies of MBL2 allelic variants (B, C, D, and X) were estimated among 345 HIV-exposed children and 147 blood donors. AIDS-free time was evaluated for different MBL2 genotypes and MBL plasma levels. The median duration of follow-up was 96.5 months. RESULTS In the Argentinean population, gene frequencies of MBL2 variants were 18%, 15%, and 3% for the X, B, and D alleles, respectively, with no identified C allele. The haplotype XA/XA was associated with an 8-fold risk of acquiring HIV-1 (P= .054; odds ratio [OR], 8.11 [95% confidence interval {CI}, 0.96-67.86]) and almost a 3-fold risk of progression to pediatric AIDS (P= .026; OR, 2.81 [95% CI, 1.14-7.47]). We also found an independent positive correlation between the rate of AIDS progression and MBL plasma concentration (P= .008; OR, 1.28 [95% CI, 1.07-1.55]). CONCLUSIONS Our results demonstrate that homozygosity for the MBL2 promoter genotype XA/XA is an important genetic determinant of HIV-1 acquisition through vertical transmission and the pathogenesis of pediatric HIV/AIDS, via a mechanism that remains to be established.

Abstract
Objective To assess the rate of protocol-defined treatment failure and safety of lopinavir/ritonavir (LPV/r) and saquinavir/ritonavir (SAQ/r). Design Open-label, prospective, randomized (1:1), international multi-centre trial. Methods Adult HIV-1-infected patients were assigned LPV/r 400/100 mg twice daily or SAQ/r 1000/100 mg twice daily with two or more nucleoside reverse transcriptase inhibitors (NRTIs)/non-NRTIs. All patients, whether on or off the assigned treatment, were followed for 48 weeks. Results Of 339 randomized patients, 324 initiated assigned treatment (intention-to-treat/exposed [ITT/e] population). At 48 weeks, treatment failure occurred in 29/163 (18%) and 53/161 (33%) of patients in the LPV/r and SAQ/r arms, respectively (ITT/e, P=0.002, log rank test). In an analysis that also considered those patients who discontinued treatment as having failed treatment (ITT/e/discontinuation=failure), 40/161 (25%) LPV/r-treated individuals versus 63/161 (39%) SAQ/R-treated individuals failed treatment ( P=0.005, log rank test). Discontinuation of the assigned treatment occurred in 23/163 (14%) patients in the LPV/r-treated group, compared with 48/161 (30%) in the SAQ/r-treated group (ITT/e; P=0.001). The primary reasons for premature discontinuation were non-fatal adverse events (LPV/r: 12/163; SAQ/r: 21/161) and patients’ choice (LPV/r: 7/163; SAQ/r: 8/161). In the on-treatment analysis of time to treatment failure, no difference was observed between the two arms ( P=0.27, log rank test). Conclusion LPV/r had better antiretroviral effects compared with SAQ/r at the doses and in the formulations studied. This may have been a result of patients’ preferences and ability to adhere to assigned therapy, rather than a result of differences in the intrinsic potency of the study protease inhibitors.

Abstract
Objective To evaluate health-related quality of life (HRQoL) changes in patients treated with indinavir three-times daily after switching to a twice-daily indinavir/ritonavir regimen or continuing with the same regimen. Methods Patients on HAART including indinavir three-times-daily with undetectable viral load were randomly assigned to continue with this therapy or to change to a twice-daily indinavir/ritonavir (800/100 mg) regimen. The Medical Outcomes Study HIV Health Survey (MOS-HIV) questionnaire was used as the HRQoL measure. Results A total of 118 patients participated in the study, of which 59 (50%) were randomly assigned to continue with the three-times-daily regimen. Patients had a mean age of 39 years and 80% of them were male. At baseline, subjects included in the three-times-daily group presented a significantly greater number of symptoms than subjects in the twice-daily group, but no statistically significant differences were observed in MOS-HIV scores between the groups. In the intention-to-treat (ITT) analysis, a reduction in HRQoL scores was observed in both groups, which was greater in the twice-daily group. In the per protocol analysis, reduction of HRQoL was minimal. Conclusions A HRQoL deterioration, greater in the twice-daily group, was observed in this study in the ITT analysis, while HRQoL remained stable in both groups in patients who continued with and tolerated the allocated regimen.

Abstract
If CC chemokine receptor 5 (CCR5)-dependent mechanisms at the time of initial virus exposure are important determinants of virus entry and disease outcome, then the polymorphisms in CCR5 that influence risk of transmission and disease progression should be similar; this hypothesis was tested in a cohort of 649 Argentinean children exposed perinatally to human immunodeficiency virus type 1 (HIV-1). Two lines of evidence support this hypothesis. First, CCR5 haplotype pairs associated with enhanced risk of transmission were the chief predictors of a faster disease course. Second, some of the haplotype pairs associated with altered rates of transmission and disease progression in children were similar to those that we previously found influenced outcome in European American adults. This concordance suggests that CCR5 haplotypes may serve as genetic rheostats that influence events occurring shortly after initial virus exposure, dictating not only virus entry but, by extension, also the extent of early viral replication.

Abstract
The effects of chemokine and chemokine receptor genetic polymorphisms such as stromal derived factor 1 (SDF1-3'A), CCR2-64I, and CCR5-delta32 associated with HIV-1 transmission and/or rate of disease progression in infected study subjects remain highly controversial and have been analyzed primarily only in adults. We have investigated whether these polymorphisms may provide similar beneficial effects in children exposed to HIV-1 perinatally. The prevalence of CCR2-64I allele was significantly increased (p = .03) and the CCR2-64I genotype distribution was not in Hardy-Weinberg equilibrium, among HIV-1-exposed uninfected infants. Moreover, in the HIV-1-infected group, a delay to AIDS progression was observed among carriers of CCR2-64I allele. This is the first report that suggests a protective role of CCR2-64I allele in mother-to-infant HIV-1 transmission and documents a delay in disease progression, after the child has been infected with HIV-1. However, SDFI-3'A and CCR5-delta32 alleles did not modify the rate of HIV-1 transmission or disease progression in HIV-1-infected children.

Abstract
The authors retrospectively analyzed 863 episodes of neutropenia and fever in 635 children with cancer or hematological disease hospitalized between October 1988 and November 1994. The most frequent underlying diseases were solid tumors (45%) and acute lymphoblastic leukemia (29%). Clinical site of infection could be determined in 454 (53%) episodes. Bacteremia was documented in 114 (13%) cases. Gram-positive cocci were the microorganisms most frequently isolated (47% of the cases). Noninfectious complications could be determined in 140 (16%) episodes, and were mainly severe bleeding and metabolic impairment. The episodes were divided in two groups for comparative evaluation: group A, 404 episodes, study period 1988-1991, and group B, 459 episodes, 1992-1994. According to the results, more patients in group A than group B were younger than 1 year old and had profound neutropenia; fewer patients in group A than group B had an endovascular catheter, a higher frequency of manifest clinical site of infection at admission, and a prevalence of isolation of gram-negative bacilli. A higher percentage of patients in group B had neutropenia of more than 14 days, gram-positive cocci in culture, and lower mortality. Multivariate analysis by logistic regression in 340 patients revealed that the presence of a severe noninfectious complication, severe neutropenia, and positive blood culture correlated with high mortality rate (p < or = 0.001).

Abstract
Early and accurate diagnosis of HIV-1 infection in infants born to HIV-1-seropositive mothers is of great importance. Polymerase chain reaction (PCR), HIV culture, and p24 antigen detection assays were evaluated for their ability to detect the presence of HIV in 195 infants at risk of perinatal infection. Using the Centers for Disease Control and Prevention guidelines for assessing HIV infection status in children younger than 18 months, 70 infants (36%) were diagnosed as HIV-1 infected and 125 (64%) lacked virologic and clinical evidence of infection. PCR and HIV culture were the most sensitive laboratory markers, detecting 100% and 98% of positive samples, respectively, regardless of age at testing. HIV-1 p24 antigen assay was detected in 26 of 38 positive samples but not in negative samples. PCR was performed with three different sets of primers (SK38/SK39-SK19-gag, SK68/SK69-SK70-env, and SK150/SK431-SK102-gag). The sensitivity/specificity of the individual assays were for SK19, 96.1%/94.25%; SK70, 89.6%/100%; and SK102, 100%/100%. A sample was considered HIV-1 positive when two positive PCR results were obtained with two different pairs of primers, and negative if the sample was negative when three sets of primers were used. False-positive results were occasionally obtained with probe SK19 in six seroreverter infants before serologic status was known. This suggested that the infection was caused by nonreplicative strains or were false-positive results probably by nonspecific amplification due to cross-reaction with other microorganisms; contamination was discarded because there was no specific amplification with the other two primers. All the HIV-1-infected infants were correctly identified with PCR; all except one could be identified with coculture and only 68.4% were confirmed with p24 antigen assay. No seroreverter infant was misdiagnosed using the criteria selected.

Abstract
Viral infections of the nervous system make up a wide range of disorders with a mainly benign outcome. However, in some cases there is severe, morbimortality. In viral encephalitis there is direct involvement of the brain parenchyma which is seen clinically as reduced consciousness, convulsions and/or focal neurological deficit. The especial attraction of some viruses for particular cells or structures determines the variety of clinical findings. The incidence and frequency of the various agents depends on several factors (geographical location of a certain virus, age and general health of the population concerned, etc.). In areas free of arbovirus the commonest aetiologies are; varicella, herpes simplex, parotiditis and enterovirus. Modern treatment (transplants, chemotherapy) of previously fatal diseases and the AIDS epidemic have increased the number of immunodeficient patients; the population is susceptible to viral infections of the nervous system which are infrequent (e.g. cytomegalovirus, papovavirus) or which follow a different course (e.g. measles, enteroviruses) to that in immunocompetent patients. Specific conditions are reviewed. Improvement in the general health and sanitation of the population, and the universal use and development of new vaccines will significantly reduce the incidence of viral encephalitis. Improved prognosis will be related to the use of modern laboratory techniques which permit early, sensitive, specific diagnosis and the development of antiviral agents.

Abstract
BACKGROUND Previously we demonstrated that monocyte phagolysosomal fusion is impaired in chronic HIV infection in adult patients. METHODS We studied the phagolysosomal fusion of peripheral blood monocytes from 45 children vertically infected with HIV, 38 noninfected infants born to HIV-positive mothers and 14 children born to HIV-seronegative women, by a cytomorphologic method in which acridine orange is used as a fusion marker. RESULTS The mean percentages of phagolysosomal fusion +/-SD were 42 +/- 16.1 for HIV-positive children, 55.3 +/- 15.5 for HIV-negative infants born to HIV-infected mothers and 58.2 +/- 12.7 for normal controls. Monocyte phagolysosomal fusion of HIV-infected children was significantly decreased in comparison to noninfected and normal infants (P < 0.001), while there was no difference between the two latter groups. Phagolysosomal fusion impairment in HIV-infected infants inversely correlated with age (r = -0.4527; P < 0.002) and directly correlated with CD4+ T cell counts (r = 0.393; P = 0.03). Moreover, phagolysosomal fusion strongly correlated with clinical manifestations; this function was significantly impaired in moderately and severely symptomatic HIV-infected children with respect to those who remained asymptomatic or mildly symptomatic (P < 0.05). CONCLUSIONS Our results suggest that monocyte function in HIV-infected children progressively deteriorates, closely related to the severity of the clinical symptoms.

Abstract
A total of 64 psychiatric patients were tested with the Italian version of the Karolinska Psychodynamic Profile in order to investigate interobserver and test-retest reliability. The mean inter-observer agreement coefficients (rho) ranged from 0.75 to 0.80 with less experienced psychiatrists, while the mean rho value was higher (0.96) with more experienced raters. Test-retest values were good, ranging from 0.53 to 0.93. Overall, reliability was comparable with that reported in the original Swedish study.

Abstract
The aim of this study was to determine the causes of fever of unknown origin, to evaluate new diagnostic tests and to elucidate risk factors for chronic or life-threatening disorders. The medical records of 113 children who had undiagnosed fever for at least 3 weeks were reviewed. Infection (N = 41) was the most frequent cause of fever of unknown origin. Respiratory tract infections were the most common causes in infants and endocarditis and tuberculosis were more frequent in older children. Neoplastic disorders (N = 11) occurred in children older than one year. Juvenile rheumatoid arthritis (N = 9) was the most common collagen-vascular disorder (N = 15). Miscellaneous disorders and factitious fever occurred in 21 and 4 cases, respectively. Twenty-two patients remained undiagnosed. History and physical examination led to a final diagnosis in 81% of cases. Abdominal ultrasonography was performed in 71 patients (61%) and was helpful for diagnosis in 15%. Children with life-threatening or chronic disorders (N = 58) were older than those with self-limiting conditions (N = 55; P = 0.017). Cardiovascular and articular signs and symptoms were more frequent in the former group (P = 0.01).

Abstract
Thirty patients with endocarditis caused by penicillin-susceptible streptococci were enrolled in one of two groups in this study. Fifteen patients received ceftriaxone (2 g once daily) for 4 weeks; the other 15 received the same dosage of ceftriaxone for 2 weeks and then received oral amoxicillin (1 g four times a day) for 2 weeks. For the 27 patients treated predominantly as outpatients, 380 days of hospitalization were avoided. Clinical cure was achieved for all patients in both groups. We conclude that ceftriaxone, alone or followed by a course of amoxicillin, is an efficacious mode of treatment for infective endocarditis caused by penicillin-susceptible streptococci. Treatment with these agents can be administered predominantly on an outpatient basis.
