RESUMO
In this study, time domain diffuse optical spectroscopy is performed in the range 600-1100 nm on 11 healthy volunteers with a portable system for the quantitative characterization of breast tissue in terms of optical properties and optically-derived blood parameters, tissue constituent concentrations, and scattering parameters. A measurement protocol involving different geometries (reflectance and transmittance), subject's positions (sitting and lying down), probing locations (outer, lower, and inner breast quadrants), and source-detector distances (2 and 3 cm) allowed us to investigate the effect of tissue heterogeneity and different measurement configurations on the results with the aim of identifying the best experimental conditions for the estimate of breast density (i.e., amount of fibro-glandular tissue in the breast) as a strong independent risk factor for breast cancer. Transmittance results, that in previous studies correlated strongly with mammographic density, are used as a reference for the initial test of the simpler and more comfortable reflectance measurement configuration. The higher source-detector distance, which probes deeper tissue, retrieves optical outcomes in agreement with higher average density tissue. Similarly, results on the outer quadrants indicate higher density than internal quadrants. These findings are coherent with breast anatomy since the concentration of dense fibro-glandular stroma is higher in deep tissue and towards the external portion of the breast, where the mammary gland is located. The dataset generated with this laboratory campaign is used to device an optimal measurement protocol for a future clinical trial, where optical results will be correlated with conventional mammographic density, allowing us to identify a subset of wavelengths and measurement configurations for an effective estimate of breast density. The final objective is the design of a simplified, compact and cost-effective optical device for a non-invasive, routine assessment of density-associated breast cancer risk.

BACKGROUND: Dysbiotic biliary bacterial profile is reported in cancer patients and is associated with survival and comorbidities, raising the question of its effect on the influence of anticancer drugs and, recently, the suggestion of perichemotherapy antibiotics in pancreatic cancer patients colonized by the Escherichia coli and Klebsiella pneumoniae. OBJECTIVE: In this study, we investigated the microbial communities that colonize tumours and which bacteria could aid in diagnosing pancreatic and biliary cancer and managing bile-colonized patients. METHODS: A retrospective study on positive bile cultures of 145 Italian patients who underwent cholangiopancreatography with PC and EPC cancer hospitalized from January 2006 to December 2020 in a QA-certified academic surgical unit were investigated for aerobic/facultative-anaerobic bacteria and fungal organisms. RESULTS: We found that among Gram-negative bacteria, Escherichia coli and Pseudomonas spp were the most frequent in the EPC group, while Escherichia coli, Klebsiella spp, and Pseudomonas spp were the most frequent in the PC group. Enterococcus spp was the most frequent Gram-positive bacteria in both groups. Comparing the EPC and PC, we found a significant presence of patients with greater age in the PC compared to the EPC group. Regarding Candida spp, we found no significant but greater rate in the PC group compared to the EPC group (11.7% vs 1.96%). We found that Alcaligenes faecalis was the most frequent bacteria in EPC than the PC group, among Gram-negative bacterial species. CONCLUSIONS: Age differences in gut microbiota composition may affect biliary habitats in our cancer population, especially in patients with pancreatic cancer. Alcaligenes faecalis isolated in the culture of bile samples could represent potential microbial markers for a restricted follow-up to early diagnosis of extra-pancreatic cancer. Finally, the prevalence of Candida spp in pancreatic cancer seems to trigger new aspects about debate about the role of fungal microbiota into their relationship with pancreatic cancer.

Knowledge of human papillomavirus transmission from the genital tract to the oral mucosa remains unsatisfactory, with poor and often inconsistent literature results. The increase in HPV-associated oral malignancies prompts further analysis of the simultaneous detection of the virus in the two anatomical areas and on the identification of genotypes to be included in future vaccines. Therefore, in this retrospective study, we evaluated orogenital HPV concurrence, hrHPV, lrHPV and type-concordance in 337 samples, as well as the prevalence of the most common genotypes not included in HPV vaccines. Concurrence was found in 12.5% (31/248) of cases, hr-concordance in 61.3% (19/31) and lr-concordance in 12.9% (4/31). Finally, type-concordance was found in 32.3% (10/31) of concurrent infections. Regarding the identification of non-vaccine genotypes, the significantly prevalent genotypes in the anogenital area were HPV66 (12.6%, p < 0.0001), HPV53 (11.1%, p < 0.0001), HPV51 (8.7%, p < 0.0001), HPV42 (8.2%, p < 0.0001) and HPV68 (5.6%, p = 0.0034) in women and HPV66 (14.6%, p = 0.0058), HPV42 (12.2%, p = 0.0428), HPV51 (12.2%, p = 0.0428), HPV53 (12.2%, p = 0.0428), HPV70 (12.2%, p = 0.0428) and HPV73 (12.2%, p = 0.0428) in men. Considering the results of our study, we recommend including the high-risk genotypes HPV51, HPV68, HPV53 and HPV66 in future HPV vaccine formulations.
RESUMO
Background: There is minimal information regarding sleep disturbance and burnout during COVID-19 in nurses working within haematology-oncology and hematopoietic stem cell transplantation (HSCT) settings.Aim: To identify socio-demographic and professional factors that predicted burnout and sleep disturbance during COVID-19 in nurses working in HSCT settings.Design/Methods: Data were collected using the Maslach Burnout Inventory and the Pittsburgh Sleep Quality Index. Descriptive statistics and linear regression examined relationships.Results: 308 responses were received. Nurses working in outpatient settings had greater emotional exhaustion (Rpartial = -0.12, n = 308, p = 0.03). Negative predictors for quality of sleep were transplant programme setting (Rpartial = -0.19, n = 308, p < 0.01) and years working in HSCT (Rpartial = -0.17, n = 308, p < 0.01). Other relationships were found on univariate analysis.Conclusion: Institutions must offer programmes for nurses to develop sleep strategies, self-care, and work-related stress management.

Genetic predisposition, environmental factors, and infectious agents interact in the development of gastric diseases. Helicobacter pylori (Hp) and Epstein-Barr virus (EBV) infection has recently been shown to be correlated with these diseases. A cross-sectional study was performed on 100 hospitalized Italian patients with and without gastric diseases. The patients were stratified into four groups. Significant methylation status differences among CDH1, DAPK, COX2, hMLH1 and CDKN2A were observed for coinfected (Hp-EBV group) patients; particularly, a significant presence of COX2 (p = 0.0179) was observed. For microsatellite instability, minor stability was described in the Hp-HBV group (69.23%, p = 0.0456). Finally, for p53 mutation in the EBV group, exon 6 was, significantly, most frequent in comparison to others (p = 0.0124), and in the Hp-EBV group exon 8 was, significantly, most frequent in comparison to others (p < 0.0001). A significant positive relationship was found between patients with infection (Hp, EBV or both) and p53 mutation (rho = 0.383, p = 0.0001), methylation status (rho = 0.432, p < 0.0001) and microsatellite instability (rho = 0.285, p = 0.004). Finally, we observed among infection and methylation status, microsatellite instability, and p53 mutation a significant positive relationship only between infection and methylation status (OR = 3.78, p = 0.0075) and infection and p53 mutation (OR = 6.21, p = 0.0082). According to our analysis, gastric disease in the Sicilian population has different pathways depending on the presence of various factors, including infectious agents such as Hp and EBV and genetic factors of the subject.

PURPOSE: Depressive disorders are the most common manifestation of psychological distress in allogenic hematopoietic stem cell transplantation. Few studies have yet investigated the relationship between therapeutic educational interventions and outcomes in these patients with specific attention to those related to mental health. Aim of this study was to understand how much educational intervention can represent a protective factor in preventing psycho-emotional distress-related issues in this setting. DESIGN: A prospective observational study of a multicenter cohort was conducted. PARTICIPANTS: Adult patients undergoing allogeneic hematopoietic stem cell transplantation. METHODS: A pre-transplant therapeutic educational programme was offered to a cohort of adult patients undergoing allo-HSCT recruited in ten transplant centers of the GITMO network between May 2018 and January 2019. Depression, Anxiety and Stress scale was used to collect data on psycho-emotional distress at admission (T0), at the day of transplant (T1) and at discharge (T2). Descriptive data were collected and reported, and comparative analyses were done among patients who were compliant with the pre-transplant educational intervention and those who did not (for any reason). FINDINGS: A cohort of 133 allo-HSCT patients was observed. In patients who did not receive pre-transplant educational intervention, higher levels of depression at admission (p = 0.01) and at the day of transplant (p = 0.03), higher levels of anxiety (p = 0.01 and p = 0.01 respectively) as well as higher levels of stress (p < 0.01 and p = 0.01) were observed. Problem solving and "face to face" interview were the best methods to provide education to patients. Those who received pre-transplant education through "face-to-face" interview reported significant low levels of depression during the whole hospital stay period (p < 0.01; p = 0.01; p = 0.01) and less anxiety and stress at admission (p < 0.05 and p = 0.01 respectively). Depression was more represented in female than male participants at T0 (16.5% vs 9.0%; p = 0.01), while among T0 and T2 the males had a significant higher increasing of depression than females (p = 0.03). CONCLUSION: Our study demonstrated that pretreatment therapeutic educational programs with specific learning modalities can be effective in limiting the potential risk of developing moderate-to-severe anxiety-depressive states and stress symptoms related to allo-HSCT. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS: Further studies are needed to confirm our results and to understand whether containing psycho-emotional distress can have any relationship with medium- and long-term post-transplant complications.
RESUMO
Nowadays, the striking numbers of infertile couples that turn to assisted reproductive technologies (ART) drive the research toward a more comprehensive understanding of the underlying causes. Male factors contribute to the inability to conceive in half of the cases, and it has been suggested that sexually transmitted infections could have a role in the onset of spermatozoa impairments. Since the impact of HPV infection on sperm quality and sperm DNA integrity is debated, we wanted to analyze its impact on conventional seminal parameters and the sperm DNA fragmentation index (DFI). Therefore, 117 semen samples of patients undergoing IVF were evaluated for the following characteristics: HPV DNA detection and sperm DNA fragmentation, concentration, motility, and morphology. The results showed a higher rate of HPV-negative patients (59.8% vs. 40.2%) and no HPV-related effect on DFI, sperm concentration, total sperm number, and total motility. Only progressive motility and morphology were found as significantly influenced by HPV positivity. Moreover, we observed a statistically significant difference in DFI when comparing high-risk HPV (HR-HPV) and low-risk HPV (LR-HPV) genotypes. Our data suggest that the presence of any HPV type, whatever the exact localization of the virions, can impair some sperm parameters, while HR-HPVs specifically affect the integrity of spermatozoa DNA.
RESUMO
Microbiotas are the range of microorganisms (mainly bacteria and fungi) colonizing multicellular, macroscopic organisms. They are crucial for several metabolic functions affecting the health of the host. However, difficulties hamper the investigation of microbiota composition in cultivating microorganisms in standard growth media. For this reason, our knowledge of microbiota can benefit from the analysis of microbial macromolecules (DNA, transcripts, proteins, or by-products) present in various samples collected from the host. Various omics technologies are used to obtain different data. Metagenomics provides a taxonomical profile of the sample. It can also be used to obtain potential functional information. At the same time, metatranscriptomics can characterize members of a microbiome responsible for specific functions and elucidate genes that drive the microbiotas relationship with its host. Thus, while microbiota refers to microorganisms living in a determined environment (taxonomy of microorganisms identified), microbiome refers to the microorganisms and their genes living in a determined environment and, of course, metagenomics focuses on the genes and collective functions of identified microorganisms. Metabolomics completes this framework by determining the metabolite fluxes and the products released into the environment. The gallbladder is a sac localized under the liver in the human body and is difficult to access for bile and tissue sampling. It concentrates the bile produced in the hepatocytes, which drains into bile canaliculi. Bile promotes fat digestion and is released from the gallbladder into the upper small intestine in response to food. Considered sterile originally, recent data indicate that bile microbiota is associated with the biliary tract's inflammation and carcinogenesis. The sample size is relevant for omic studies of rare diseases, such as gallbladder carcinoma. Although in its infancy, the study of the biliary microbiota has begun taking advantage of several omics strategies, mainly based on metagenomics, metabolomics, and mouse models. Here, we show that omics analyses from the literature may provide a more comprehensive image of the biliary microbiota. We review studies performed in this environmental niche and focus on network-based approaches for integrative studies.
RESUMO
Legionella is a ubiquitous bacterium that lives in freshwater environments and colonizes human-made water systems. Legionella pneumophila is the most virulent species, and risk factors for Legionnaires' disease include increasing age, smoking, chronic diseases, and immunodeficiency. For this reason, it is very important to assess and monitor hospital water systems in order to prevent legionellosis. We have monitored a large hospital in Palermo for four years. To determine the presence of microorganisms, according to national guidelines, we used the culture method, which is considered the gold standard for Legionella detection. Sampling was divided into five macro-areas, and a total of 251 samples were collected during the period of investigation, 49% of which were Legionella spp.-positive and 51% were Legionella spp.-negative. Positive samples with L. pneumophila. sgr 2-15 were most frequent in the Underground (55.6%, p = 0.0184), Medicine (42.9%, p = 0.0184) and Other (63.2%, p = 0.002) areas; while positive samples for L. pneumophila sgr 1 were less frequent in the Underground (0.0%, p = 0.0184) and Surgery areas (4.5%, p = 0.033), and for Legionella anisa, were less frequent in the Medicine (4.1%, p = 0.021), Oncohematology (0.0%, p = 0.0282), and Other (0.0%, p = 0.016) areas. Finally, no significant differences were observed among the areas for each isolate considered. The surveillance carried out in these years demonstrates the importance of monitoring, which allows us to analyze the conditions of hospital facilities and, therefore, prevent Legionella spp. infections.
RESUMO
BACKGROUND: Oral mucositis (OM) is one of the most debilitating effects of toxicity due to hematopoietic stem cell transplantation (HSCT) conditioning regimens. The aim of this secondary analysis of the data of a phase II study designed to assess the efficacy of a novel oral care protocol containing bovine colostrum and aloe vera to prevent oral mucositis was to compare outcomes reported by patients with those collected by healthcare professionals (HCPs). METHOD: Data on oral mucositis severity, duration, time of onset and related pain were collected from patients using the Oral Mucositis Daily Questionnaire (OMDQ). HCPs assessed the same outcomes using the World Health Organization oral mucositis scale and pain numerical rating scale. Quality of life was assessed with the 3-level EuroQol-5 dimensions. RESULTS: Fifty-nine autologous/allogeneic graft patients were recruited, 46 of whom (78.0%) experienced OM. Mean onset was 9.1 (SD ± 3.5) days after conditioning initiation, mean duration was 10.4 (SD ± 4.3) days, and the average maximum pain score was 3.7 (SD ± 2.7). Self-administration of the OMDQ detected oral symptoms at least 1 day sooner compared to objective assessments (p = 0.025). Significant differences were observed between the patient-reported and the HCP-assessment data on oral mucositis severity grading distribution (p < 0.0001) and highest pain score (p < 0.0001). Quality of life score variations were correlated with changes in oral mucositis severity during patients' hospital stay. CONCLUSIONS: Further studies are necessary to improve the understanding of these findings; a randomised controlled trial is being set up at our institution.

BACKGROUND AND OBJECTIVE: Northern Italy was one of the first European territories to deal with the Coronavirus Disease 2019 (COVID-19) outbreak. Drastic emergency restrictions were introduced to contain the spread and limit pressure on healthcare facilities. However, nurses were at high risk of developing physical, mental, and working issues due to professional exposure. The aim of this cross-sectional study was to investigate these issues among nurses working in Italian hematopoietic stem cell transplant (HSCT) centers during the COVID-19 pandemic. METHODS: Data were collected online immediately after the first "lockdown" period in order to investigate the prevalence of physical issues, sleep disorders, and burnout symptoms and explore correlations with COVID-19 territorial incidence in Northern Italian regions versus Central and Southern Italian regions. RESULTS: Three hundred and eight nurses working in 61 Italian HSCT Units responded to the survey. Depression, cough, and fever were more frequently reported by nurses working in geographical areas less affected by the pandemic (p=0.0013, p<0.0001, and p=0.0005 respectively) as well as worst sleep quality (p=0.008). Moderate levels of emotional exhaustion (mean±SD -17.4±13.0), depersonalization (5.3±6.1), and personal accomplishment (33.2±10.7) were reported without significant differences between territories. CONCLUSIONS: different COVID-19 incidence among territories did not influence nurses' burden of symptoms in the HSCT setting. However, burnout and insomnia levels should be considered by health care facilities in order to improve preventive strategies.
RESUMO
WHAT IS KNOWN AND OBJECTIVE: The aim of this survey, conducted by the Gruppo Italiano per il Trapianto di Midollo Osseo (GITMO), was to evaluate the involvement of pharmacists in the haematopoietic stem cell transplant (HSCT) program in Italian adult and paediatric centres. METHODS: A 63-item online questionnaire was developed and sent to the Italian Transplant Programs on behalf of GITMO. RESULTS AND DISCUSSION: Overall, 54.7% of the Italian HSCT centres participated in the survey (88.5% adult, 7.7% paediatric, 3.8% mixed), of which 50% were in public hospitals and 50% affiliated with public universities. Just over 80% declared that a pharmacist is involved in the HSCT centre, and 86.5% reported the presence of a documentation system to signal of adverse events, accessible by physicians, nurses and pharmacists in 57.7%. Chemotherapy drugs were centralized in the pharmacy in 98.1% of HSCT centres, while parenteral nutrition was centralized in 55.8%. The use of off-label drugs was authorized by an internal committee and by the regional health authorities in 88.5% of the centres. On univariate analysis, few statistically significant differences were found on response frequencies between public hospitals and university centres or between HSCT centres performing only autologous stem cell transplantation versus other centres performing autologous and allogeneic stem cell transplantation. WHAT IS NEW AND CONCLUSION: This survey suggests that there is good collaboration between pharmacists and physicians and nurses in Italian HSCT transplantation centres. The enhancement of pharmacists dedicated to HSCT programs could improve some problems, for example, the centralization of parenteral nutrition.

PURPOSE: Pulmonary hamartoma is the most common benign tumor of the lung. We analyzed a 20-year historical series of patients with pulmonary hamartoma undergoing surgical resection, aiming to evaluate the characteristics, the outcomes, and the association between hamartoma and lung cancer. METHODS: It was a retrospective multicenter study including the data of all consecutive patients with pulmonary hamartoma undergoing surgical resection. The end-points were to evaluate: (i) the characteristics of hamartoma, (ii) outcomes, and (iii) whether hamartoma was a predictive factor for lung cancer development RESULTS: Our study population included 540 patients. Upfront surgical or endoscopic resection was performed in 385 (71%) cases while in the remaining 155 (29%) cases, the lesions were resected 20 ± 3.5 months later due to increase in size. In most cases, lung sparing resection was carried out including enucleation (n = 259; 48%) and wedge resection (n = 230; 43%) while 5 (1%) patients underwent endoscopic resection. Only two patients (0, 2%) had major complications. One patient (0.23%) had recurrence after endoscopic resection, while no cases of malignant degeneration were seen (mean follow-up:103.3 ± 93 months). Seventy-six patients (14%) had associated lung cancer, synchronous in 9 (12%) and metachronous in 67 (88%). Only age > 70-year-old (p = 0.0059) and smokers > 20 cigarettes/day (p < 0.0001) were the significant risk factors for lung cancer. CONCLUSION: PH was a benign tumor, with no evidence of recurrence and/or of malignant degeneration after resection. The association between hamartoma and lung cancer was a spurious phenomenon due to common risk factors.

BACKGROUND: Here, we report our initial experience with subxifoid video-assisted thoracoscopic surgery (SVATS) lobectomy for the management of primary lung cancer, and compared the outcomes of SVATS with those of conventional transthoracic VATS (CVATS) lobectomies to validate its feasibility and usefulness. METHODS: The clinical data of consecutive patients undergoing VATS lobectomy via SVATS or CVATS for lung cancer were retrospectively compared. The endpoints were to evaluate the statistical differences in surgical results, postoperative pain (measured with visual analog scale [VAS] scores at 8 hours, Day 1, Day 2, Day 3, at discharge, one month and three months after surgery) and paresthesia (measured at one- month, and three months after surgery). The two groups were compared before and after matching analysis. RESULTS: Our study population included 223 patients: 84 in the SVATS and 139 in the CVATS group. The two groups were not comparable for sex (P = 0.001), preoperative comorbidity as cardiopathy (P = 0.007), BMI value (P = 0.003), left-sided procedure (P = 0.04), tumor stage (P = 0.04), and tumor size (P = 0.002). These differences were overcome by propensity score matching (PSM) analysis that yielded two well-matched groups which included 61 patients in each group. Surgical outcomes including blood loss, hospital stay and complications were similar before and after matching analysis, but SVATS compared to CVATS was associated with longer operative time before (159 ± 13 vs. 126 ± 6.3, P < 0.0001), and after matching analysis (161 ± 23 vs. 119 ± 8.3; P < 0.0001) and significant reduction of postoperative pain during the different time-points (P < 0.001), and paresthesia at one (P = 0.001), and three months (P < 0.0001). CONCLUSIONS: SVATS lobectomy is a feasible and safe strategy with surgical outcomes similar to CVATS lobectomy but with less postoperative pain and paresthesia. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: Subxifoid thoracoscopic lobectomy is a feasible and safe procedure, with potential benefits in terms of postoperative pain and paresthesia compared to conventional thoracoscopic lobectomy Our results showed that surgical outcomes including blood loss, hospital stay, morbidity and mortality are similar but subxifoid thoracoscopy was associated with significant reduction of postoperative pain and paresthesia. WHAT THIS STUDY ADDS: Subxifoid thoracoscopy is a safe procedure; compared to conventional transthoracic thoracoscopy, it avoids intercostal incisions, and spares nerve trauma, resulting in a reduction of postoperative pain and paresthesia.

Human papilloma virus infection (HPV) is the most common sexually transmitted disease. Little is known about male infection. Nonavalent vaccine against types 6/11/16/18/31/33/45/52/58 was approved and neutral gender immunization programs have been proposed. This study evaluates the potential impact of nonavalent vaccine compared to quadrivalent in male living in Sicily (Italy). 58.7% of samples were HPV positive and forty-four types of HPV were identified. A significant higher estimated coverage of nonavalent vaccine than quadrivalent was observed (64.3% vs. 45.8%), with absolute and relative additional impact of 20.1% and 47.2%, respectively. Low impact of the vaccine were calculated as the empirical probability of HPV genotypes 6/11/16/18/31/33/45/52/58 alone or in combination; the high impact as empirical probability of HPV6/11/16/18/31/33/45/52/58 genotypes alone or in association with other genotypes. The potential impact of the nonavalent vaccine vs quadrivalent was significant for low and high impact (29.7% > 18:8%; 34:6% > 26.6%, respectively). Particularly, in men with lesions and risky sexual contact was significant only for low impact (35.5% > 29.7%; 31.4% > 19.7%, respectively). In partners with positive females was significant for low impact (26.3% > 15.1%) and high impact (33.7% > 23.2%). Nonavalent vaccine offers broader protection in men with HPV positive partners, who would have a potential role in the transmission of the infection.

This paper discusses the use of advanced mathematical tools in nursing research, such as mathematical models used in medicine for description and prediction of experimental tumor growth. They are rarely used in nursing research, but fortunately in the last decade, their use is increased, mainly due to artificial intelligence and Big Data, with great benefits for further nursing development. Therefore, a strong interaction between nurses and mathematicians is needed to improve nursing research, and consequently, the nurses' performance in daily work.
RESUMO
PURPOSE: Insufficient knowledge of primary immune thrombocytopenia purpura (ITP) in the elderly, together with a lack of clinical trial data, has resulted in wide variation in treatments. Here, we present a study focused on clinical characteristics of ITP in older subjects at diagnosis integrated with the subsequent course of the disease and treatment history. METHODS: In a retrospective monoinstitutional study, we evaluated >65-year-old patients with primary ITP. Clinical characteristics at the time of diagnosis were described and analyzed. We aimed to delineate whether subsequent lines of therapy influenced the number of relapses. In addition to initial regimens, we reported subsequent treatments and the impact on relapse trends. RESULTS: A total of 50 patients (56% males, mean age 78 years) were included. With regard to clinical variables at diagnosis, statistical significance was found for Eastern Cooperative Oncology Group performance status 1 (46% of patients, p<0.0001), presence of three comorbidities (36% of patients, p<0.0001), World Health Organization grade 0 bleeding (46%, p=0.0001), and World Health Organization grade 1 bleeding (42%, p=0.0009). For bleeding sites, the most frequent were skin or mucosa (40%, p=0.0477). A decrease in platelet count was correlated with moderate or severe bleeding (ρ=-0.52, p=0.0001) and viscera or skin/mucosa + viscera site (ρ=-0.50, p=0.0002). Finally, a decreasing number of patients required treatment from first-line therapy to sixth (p<0.0001). Relapse was most frequent before second-line therapy (54%, p<0.0001) and less frequent before fivth and sixth (4%, p=0.0072; 2%, p=0.0027). CONCLUSION: ITP in older age poses considerable challenges, so specific management strategies should be considered to optimize outcomes. Our findings provide evidence of an inverse relationship between lines of therapy and timing of relapses. This study does not exclude the possibility that agents used after first-line therapy may have an impact on the response and modify the unfavorable course of ITP.
RESUMO
Background Infective endocarditis (IE) is an uncommon disease with an involved interplay of clinical and surgical team management. We aimed to define diagnosis parameters and delineate in-hospital management in patients with IE admitted in a tertiary hospital of Southern Italian. Materials and methods Fifty-six consecutive patients (42 males, 14 females; age range: 34-85 years) admitted for IE in the Infectious Diseases, Cardiac Surgery, and Cardiology units, between January 2011 and August 2017, were enrolled. Demographic data, mortality, comorbidities, specimen type, microscopy results, special histological staining performed, and antimicrobial therapy were collected and analyzed. Any comments at the multidisciplinary team meetings were recorded in minutes of and approved. Results We found 83.9% of patients with positive blood cultures. The four most common bacteria were methicillin-resistant Staphylococcus aureus (MRSA: 21.3%), methicillin-sensitive Staphylococcus aureus (MSSA: 17%), Streptococci (14.9%), and Enterococci (14.9%). Both in the univariate and multivariate analysis, we observed a significant positive correlation between surgery and complications. Particularly in the univariate analysis only, surgery was positively correlated to males and C-reactive protein (CPR) at baseline. Also, considering the most common bacteria, it resulted in a positive correlation between surgery and MRSA and Streptococci spp. and between complications and MSSA. Finally, the male gender was positively correlated to MSSA and heart complications, major arterial embolism, septic pulmonary emboli, splenic infarction, and cerebral embolism. Conclusions A blood culture test remains a critical factor for the diagnosis of IE and the antibiotic treatment of susceptible and emerging resistant bacteria. Male gender and heart complications are red flags for prompt operative management.
RESUMO
Ultrasound (US) is highly accurate in the diagnosis of small bowel obstruction (SBO). Because the indications for and timing of surgical intervention for SBO have changed over the past several decades, there is a widespread assumption that the majority of patients with simple SBO may be conservatively managed; in this scenario, staging SBO is crucial. This study evaluated the association between morphological and functional US signs in the diagnosis and staging (simple, decompensated and complicated), and the associations and prevalence of US signs correlated with clinical or surgical outcome. The US signs were divided into diagnostic (dilated bowel loops and altered kinesis) and staging criteria (extraluminal free fluid, parietal and villi alterations). We performed a retrospective, single-center cohort, observational study examining the prevalence of morphologic and functional US signs in the staging of simple, decompensated and complicated SBO. The most significant US signs were dilated bowel loops (100%), hypokinesis (90.46%), thickened walls (82.54%) and free fluid (74.60%). By linear regression, free fluid was positively correlated to US staging in both univariate and multivariate analysis; that is, the more advanced the stage of SBO, the more probable the presence of free fluid between the bowel loops. In univariate analysis only, we found a positive correlation between US staging/thickened walls and the prominence of valvulae conniventes. Additionally, the multivariate analysis indicated that parietal stratification and bowel jump kinesis were negative predictors for US staging in comparison to other US signs. In addition, we found significant associations between conservative treatment or surgery and hypokinesis (p = 0.0326), akinesis (p = 0.0326), free fluid (p = 0.0013) and prominence of valvulae conniventes (p = 0.011). Free fluid in particular was significantly less present in patients that were conservatively treated (p = 0.040). We conclude that the US staging of SBO may be crucial, with a valuable role in the initial diagnosis and staging of the pathology, saving time and reducing total radiation exposure to the patient.
RESUMO
BACKGROUND: The management of chronic diseases, particularly in children, requires an integrated physical and psychological approach to both sick children and their family. This is the case of Cystic Fibrosis (CF), a complex genetic chronic disease, where, a comprehensive evaluation of the emotional impact and an effective multidimensional approach are indicated. AIM: This study investigates on parenting stress in children and adolescents with CF and its determinants related to parents, children and the disease severity. METHODS: The study involved 34.04% adult males and 65.96% adult females (range 21-55 years) and 47 children with CF, 54.35% males and 45.65% females (range 1-17 years). The data were obtained through a Parenting Stress Index - Short Form (PSI-SF) questionnaire. According to the PSI-SF scoring system, three types of stress were detected: a typical stress pattern (normal), a high stress pattern (increased) and a defensive response, which may be considered as a high stress feature in children which requires monitoring and clinical evaluation. RESULTS: This study shows a significant presence of stress in females (60.23%), of subject married (84.62%), unemployed (69.23%) and with education level such as "middle School" (61.54%). Concerning children of parents with high stress, it resulted most frequent children with one sibling (53.85%). Finally, by univariate analysis, it resulted a significant positive correlation between parenting stress and disease degree of children. Instead by multivariate analysis, we found that the variables: Number of siblings and Birth order were a significant positive and negative predictor of parenting stress respectively. CONCLUSION: An increased stress level was detected in less than one third of parents of subjects with CF. These data may be related to the psychological support which is part of the routine management of CF care team. However, as children's features seem to act as a determinant of stress more than parental ones, the parental-child dysfunction should be the target for further integrated interventions.
