Benefits and Safety of Empiric Antibiotic Treatment Active Against KPC-K. pneumoniae in Febrile Neutropenic Patients with Acute Leukemia Who are Colonized with KPC-K. pneumoniae. A 7-Years Retrospective Observational Cohort Study.

Purpose: To evaluate the benefits and safety of the empiric antibiotic treatment (EAT) active against KPC-K. pneumoniae in febrile neutropenic patients with acute leukaemia (AL) who are colonised by KPC-K. pneumoniae. Patients and Methods: A 7-year (2013-2019) retrospective observational cohort study was conducted at the Haematology, Sapienza Rome University (Italy) on 94 febrile neutropenia episodes (FNE) in AL patients KPC-K. pneumoniae carriers treated with active EAT. Results: Eighty-two (87%) FNE were empirically treated with antibiotic combinations [38 colistin-based and 44 ceftazidime-avibactam (CAZAVI)-based], 12 with CAZAVI monotherapy. Successful outcomes were observed in 88/94 (94%) FNE, 46/49 (94%) microbiologically documented infections, and 24/27 (89%) gram-negative bloodstream infections (GNB-BSI). Mortality due to infective causes was 4.2% (2.1% within 1 week). KPC-K. pneumoniae infections caused 28/94 FNE (30%) and KPC-K. pneumoniae-BSI was documented in 22 FNE (23.4%) (85% of GNB-BSI), in all cases patients received active EAT, and 21 survived. KPC-K.pneumoniae-BSI mortality rate was 4.5%. CAZAVI-based EAT showed better results than colistin-based EAT (55/56 vs 33/38, p = 0.037), overall and without EAT modification (41/56 vs 20/38, p = 0.02). Empirical combinations including CAZAVI were successful in 98% of cases (43/44 vs 33/38 for colistin-based EAT, p = 0.01), without modifications in 82% (36/44 vs 20/28, p = 0.02). All deaths occurred in patients treated with colistin-based EAT (4/38 vs 0/56, p = 0.02). CAZAVI-containing EAT was the only independent factor for an overall successful response (HR 0.058, CI 0.013-1.072, p = 0.058). Nephrotoxicity occurred in 3(8%) patients undergoing colistin-based EAT (none in those undergoing CAZAVI-based EAT, p = 0.02). Conclusion: KPC-K. pneumoniae infections are frequent in colonised AL patients with FNE. EAT with active antibiotics, mainly CAZAVI-based combinations, was effective, safe, and associated with low overall and KPC-K. pneumoniae-BSI-related mortality.

Acute hepatitis-like presentation with cholestasis of CBFB-MYH11-positive acute myeloid leukemia in an adult male: a case report.

BACKGROUND: Liver involvement in adults with acute myeloid leukemia is uncommon. Most of the case reports describe acute liver failure or obstructive jaundice, while acute hepatitis is rarely mentioned. We report a patient with acute myeloid leukemia who presented with clinical, biochemical, and radiological signs of acute hepatitis that totally regressed after chemotherapy. CASE PRESENTATION: A 38-year-old Caucasian man presented with fever, cough, and mild fatigue. Laboratory workup showed anemia, thrombocytopenia, severe leukocytosis, transaminitis, and hyperbilirubinemia. Imaging of the abdomen (ultrasound and magnetic resonance) showed hepatomegaly, splenomegaly, upper limits portal veins diameters, increased thickness of the gallbladder wall, and significant abdominal lymph nodes. Peripheral blood smear and bone marrow evaluation were consistent with acute myeloid leukemia, and liver biopsy showed massive sinusoidal and portal infiltration by leukemic cells. After remission-inducing chemotherapy, there was complete normalization of liver function tests, and liver, spleen, and portal vein size. CONCLUSIONS: This case highlights the importance of taking acute myeloid leukemia into account as a possible cause of liver damage to make a rapid diagnosis and start appropriate treatment that may lead to hematological remission and hepatic dysfunction resolution.

Autologous stem cell transplantation in favorable-risk acute myeloid leukemia: single-center experience and current challenges.

BACKGROUND: Autologous stem cell transplantation (ASCT) has gained growing consideration as a treatment option for favorable-risk acute myeloid leukemia (FR-AML) in first complete remission (CR1), compared with chemotherapy. MATERIALS AND METHODS: We report the long-term outcomes of 117 consecutive patients with FR-AML fit for intensive chemotherapy diagnosed in our center between 1999 and 2020, who underwent ASCT. RESULTS: Sixty-five of the 117 were eligible for intensive post-remission treatment, and 42 of those 65 received ASCT. Median follow up was 132 months. Overall survival (OS) and disease-free survival (DFS) were 75% and 76%. Higher doses of CD34 + stem cell infusions negatively impacted DFS in multivariate analysis. Core-binding factor (CBF) leukemia was an independent prognostic factor for improved DFS. No differences based on pre-transplant measurable residual disease (MRD) were observed. In CBF leukemia, 10-year DFS is 72% for MRD-positive patients versus 100% for MRD negative patients. CONCLUSIONS: ASCT is effective and safe in FR-AML patients. In CBF leukemia, ASCT provides excellent results regardless of achievement of bone marrow MRD negativity. In NPM1-mutated/FLT3-wild type (mNPM1) AML, early molecular response seems to have more impact on prognosis. Prospective investigation of the role of gemtuzumab ozogamicin in this setting is ongoing.

Physicians' Perceptions of Clinical Utility of a Digital Health Tool for Electronic Patient-Reported Outcome Monitoring in Real-Life Hematology Practice. Evidence From the GIMEMA-ALLIANCE Platform.

Digital health tools are increasingly being used in cancer care and may include electronic patient-reported outcome (ePRO) monitoring systems. We examined physicians' perceptions of usability and clinical utility of a digital health tool (GIMEMA-ALLIANCE platform) for ePRO monitoring in the real-life practice of patients with hematologic malignancies. This tool allows for the collection and assessment of ePROs with real-time graphical presentation of results to medical staff. Based on a predefined algorithm, automated alerts are sent to medical staff. Participating hematologists completed an online survey on their experience with the platform. Of the 201 patients invited to participate between December 2020 and June 2021 (cut-off date for current analysis), 180 (90%) agreed to enter the platform and had a median age of 57 years. Twenty-three hematologists with a median age of 42 years and an average of 17 years of experience in clinical practice were surveyed. All hematologists agreed or strongly agreed that the platform was easy to use, and 87%, agreed or strongly agreed that ePROs data were useful to enhance communication with their patients. The majority of physicians (78%) accessed the platform at least once per month to consult the symptom and health status profile of their patients. The frequency of access was independent of physician sex (p=0.393) and years of experience in clinical practice (p=0.404). In conclusion, our preliminary results support the clinical utility, from the perspective of the treating hematologist, of integrating ePROs into the routine cancer care of patients with hematologic malignancies.

Reduced transmission of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-KP) in patients with haematological malignancies hospitalized in an Italian hospital during the COVID-19 pandemic.

OBJECTIVES: During the lockdown that started in Italy on 10 March 2020 to address the COVID-19 pandemic, aggressive procedures were implemented to prevent SARS-CoV-2 transmission in SARS-CoV-2-negative patients with haematological malignancies. These efforts progressively reduced Klebsiella pneumonia carbapenemase-producing K. pneumoniae (KPC-KP) spread among these patients. Here we evaluated the potential effects of measures against COVID-19 that reduced KPC-KP transmission. PATIENTS AND METHODS: We analysed KPC-KP spread among 123 patients with haematological malignancies, hospitalized between March and August 2020, who were managed using measures against COVID-19. Their outcomes were compared with those of 80 patients hospitalized during the preceding 4 months (November 2019-February 2020). RESULTS: During March-August 2020, 15.5% of hospitalized patients were KPC-KP positive, compared with 52.5% in November 2019-February 2020 (P < 0.0001); 8% and 27.5% of patients in these two groups were newly KPC-KP positive, respectively (P = 0.0003). There were eight new KPC-KP-positive patients during January 2020 and none during June 2020. The weekly rate of hospitalized KPC-KP-positive patients decreased from 50% during March 2020 to 17% during August 2020. Four KPC-KP bloodstream infections (BSIs) were experienced by 123 patients (3%) in March-August 2020, and seven BSIs (one fatal) by 80 patients (8%) in November 2019-February 2020 (P = 0.02). Consumption and expense of ceftazidime/avibactam administered to KPC-KP-positive patients significantly decreased in March-August 2020. CONCLUSIONS: Aggressive strategies to prevent SARS-CoV-2 transmission were applied to all hospitalized patients, characterized by high levels of KPC-KP endemicity and nosocomial transmission. Such measures prevented SARS-CoV-2 infection acquisition and KPC-KP horizontal transmission. Reduced KPC-KP spread, fewer associated clinical complications and decreased ceftazidime/avibactam consumption represented unexpected 'collateral benefits' of strategies to prevent COVID-19.

Reduced mortality from KPC-K.pneumoniae bloodstream infection in high-risk patients with hematological malignancies colonized by KPC-K.pneumoniae.

BACKGROUND: KPC-K.pneumoniae bloodstream infection (KPC-KpBSI) mortality rate in patients with hematological malignancies is reported about 60%. The initial treatment active against KPC-K.pneumoniae is crucial for survival and KPC-K.pneumoniae rectal colonization usually precedes KPC-KpBSI. We evaluated the impact on KPC-KpBSI mortality of the preemptive use of antibiotics active against KPC-K.pneumoniae, as opposed to inactive or standard empiric antibiotics, for the empiric treatment of febrile neutropenia episodes in patients with hematological malignancy identified as KPC-K.pneumoniae intestinal carriers. METHODS: We compared the outcomes of KPC-KpBSIs occurring in high-risk hematological patients known to be colonized with KPC-K.pneumoniae, during two time periods: March2012-December2013 (Period 1, initial approach to KPC-K.pneumoniae spread) and January2017-October2018 (Period 2, full application of the preemptive strategy). The relative importance of the various prognostic factors that could influence death rates were assessed by forward stepwise logistic regression models. RESULTS: KPC-KpBSI-related mortality in hematological patients identified as KPC-K.pneumoniae carriers dropped from 50% in Period 1 to 6% in Period 2 (p < 0.01), from 58 to 9% in acute myeloid leukemia carriers(p < 0.01). KPC-KpBSIs developed in patients identified as KPC-K.pneumoniae carriers were initially treated with active therapy in 56% and 100% of cases in Period 1 and Period 2, respectively (p < 0.01), in particular with an active antibiotic combination in 39 and 94% of cases, respectively(p < 0.01). The 61% of KPC-KpBSI observed in Period 1 developed during inactive systemic antibiotic treatment (none in Period 2, p < 0.01), fatal in the 73% of cases. Overall, KPC-KpBSI-related mortality was 88% with no initial active treatment, 11.5% with at least one initial active antibiotic (p < 0.01), 9% with initial active combination. Only the initial active treatment resulted independently associated with survival. CONCLUSIONS: In high-risk hematological patients colonized by KPC-K.pneumoniae, the empiric treatment of febrile neutropenia active against KPC-K.pneumoniae reduced KPC-KpBSI-related mortality to 6% and prevented fatal KPC-KpBSI occurrence during inactive systemic antibiotic treatment.

Insomnia in patients with advanced lung cancer admitted to palliative care services.

AIM: To assess the prevalence of insomnia and possible associated factors in patients with advanced lung cancer admitted to different settings of palliative care. METHODS: Secondary analysis of a consecutive sample of patients with advanced lung cancer receiving palliative care. Epidemiological and clinical data, treatments received in the last month, Karnofsky status, Edmonton Symptom Assessment System (ESAS), Athens Insomnia Scale and the Hospital Anxiety and Depression Scale (HADS), as well as concomitant medical treatment were recorded. RESULTS: One-hundred-eight-two patients with advanced lung cancer were surveyed. The mean age was 69.9 years (SD 10.8), and 121 patients (66%) were men. The majority of patients showed consistent levels of insomnia. A poor Karnofsky level, pain, nausea, and drowsiness, time from diagnosis (1-3 years), HADS anxiety, and HADS depression, were positively associated with insomnia. CONCLUSIONS: About 50% of patients with advanced lung cancer admitted to palliative care services had relevant insomnia. Several factors associated with insomnia have been identified and should prompt physicians for a careful examination and subsequent treatment.

Early Palliative Home Care versus Hospital Care for Patients with Hematologic Malignancies: A Cost-Effectiveness Study.

Background: There is paucity of data on the potential value of early palliative home care for patients with hematologic malignancies. Objective: To compare costs, use of resources, and clinical outcomes between an early palliative home care program and standard hospital care for active-advanced or terminal phase patients. Patients and Methods: In this real-life, nonrandomized comparative study, the allocation of advanced/terminal phase patients to either home or hospital was based on pragmatic considerations. Analysis focused on resources use, events requiring blood unit transfusions or parenteral therapy, patient-reported symptom burden, mean weekly cost of care (MWC), cost-minimization difference, and incremental cost-effectiveness ratio (ICER). Results: Of 119 patients, 59 patients cared at home were more debilitated and had a shorter survival than the 60 in hospital group (p = 0.001). Nevertheless, symptom burden was similar in both groups. At home the mean weekly number of transfusions (1.45) was lower than that at hospital (2.77). Higher rate of infections occurred at hospital (54%) versus home (21%; <0.001). MWC for hospitalization was significantly higher in a 3:1 ratio versus home care. Compared with hospital, domiciliary assistance produced a weekly saving of € 2314.9 for the health provider, with a charge of € 85.9 for the family, and was cost-effective by an ICER of € -7013.9 of prevented days of care for avoided infections. Conclusions: Current findings suggest that costs of early palliative home care for patients with hematologic malignancies are lower than standard hospital care costs. Domiciliary assistance may also be cost-effective by reducing the number of days to treat infections.

Nonmelanoma skin cancer associated with Hydroxyurea treatment: Overview of the literature and our own experience.

Nonmelanoma skin cancer is the most common malignant tumor in the fair skin population, with each year several millions of diagnosed cases. Their most common risk factors are fair skin, a history of excessive ultraviolet light exposure, chronic inflammatory skin conditions, exposure to radiation, and contact with arsenic. Certain drugs can also be associated with a higher risk of nonmelanoma skin cancer. These include hydroxyurea, which acts as a metabolic inhibitor of ribonucleotide reductase and a potent nonalkylating myelosuppressive agent. It is used for the treatment of various myeloproliferative disorders, including chronic myeloid leukemia, polycythemia vera, and essential thrombocytopenia. Several publications describe an increased occurrence of skin manifestations following hydroxyurea treatment. A growing body of evidence indicates a possible role of hydroxyurea in skin cancer progression. In this review article, we summarize some relevant observations about the association of hydroxyurea and skin cancer, and we describe our own clinical experiences to provide up to date recommendations about the care of patients on hydroxyurea therapy.

[Assessment of burnout in health care personnel in hematological unit of a teaching hospital]. / Valutazione del burnout nel personale dipendente del reparto di Ematologia di un Policlinico Universitario.

OBJECTIVES: Working in such circumstances can lead to a typical emotional stress called "burnout". The aim of this study was to evaluate the perceived state of physical and mental health, and verify the existence of burnout among health care workers of Hematology unit in a Teaching Hospital. METHODS: Anonymous questionnaires were administered to healthcare professionals (physicians, nurses, health care workers). It includes socio demographic variables, the Maslach Burnout Inventory (MBI) and SF12 also. The MBI captures three dimensions of burnout: emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (RP); whereas the SF12 defines two quality of life scores: Mental Score (MCS) and Physical Score (PCS). RESULTS: Of 120 operators 70 individuals responded to the study. The questionnaire shows that the burnout levels were high in the followed part of the sample: 40% have high level of EE; 24% of DP; 15% of RP. The correlation analysis between SF12 and MBI undelines followed significance: r = -0.576 with p minor than 0.001 between EE and MCS; r = 0.557 with p minor than 0.001 between EE and DP. The three multivariate analysis refer that: the EE is associated indirectly to PCS and MCS with p mionr than 0.05; the DP is directly and significantly (p minor than 0.05) associated to MCS, "years of work" and to female gender. The RP dimension no underlines significant associations with variables studied. CONCLUSIONS: The findings were consistent with the type of work and assisted patients (chronic patient, often with poor prognosis and low expectations in terms of care and survival) that contribute to stressful situations. Personal fulfillment, instead, seems to be quite high in this contest. The relatively small sample couldn't represent the world of health care workers in hematological units, but there is no doubt that a systematic assessment of burnout, to investigate the causes of burnout are main elements to identify the potential solutions to address the phenomenon. Additional investigations of the MBI dimensions using biggest samples would be useful to confirm the results in order to generate burnout reduction measures by institutional and national policies.

Oral prolonged-release Oxycodone-Naloxone: analgesic response, safety profile, and factors influencing the response in advanced cancer patients.

BACKGROUND: Oxycodone-Naloxone (OXN) aims to reduce opioid-related constipation while being successfully analgesic. METHODS: We evaluated the analgesic response, prevalence, and severity of side effects in 176 cancer patients with moderate to severe pain and treated with OXN. Patients were followed for 28 days and evaluated every seven. Pain intensity, changes of therapy, and adverse drug reactions were recorded at each visit. The primary efficacy endpoint was the proportion of responders (≥30% reduction of pain intensity from baseline to final) and final average pain score ≤4 on a 0-10 scale. RESULTS: Average and worst pain intensity, and breakthrough pain (BTP) prevalence decreased over time and 81.3% of patients were responders. The starting daily dose of OXN was raised from 25.1±13.0 mg to 44.1±29.9 mg, and dose escalation >5%/day was observed in 19.4% of patients; 40.8-46.2% and 11.0-17.0% experienced any and severe grade of constipation during the follow-up visit, respectively. Digestive system tumor, thyroid endocrinopathies, psychological irritability, and BTP increased the risk of analgesic non-response. CONCLUSIONS: OXN had strong analgesic effect in moderate to severe cancer pain patients: the safety profile is in line with the common adverse effects of opioids and severe constipation was uncommon.

Mental and physical well-being in oncology-hematology-unit personnel.

Health care workers (HCWs) in university hematology units (UHUs) face high job demand that can have adverse health effects. This cross-sectional study investigated the relationship between some job stressors and health-related quality of life among HCWs of 3 UHUs in Rome. Work-related stress was measured with the Demand-Control Questionnaire; health-related functioning with the mental component score (MCS) and physical component score (PCS) of the Short Form 12 Survey; positivity with the Positivity Scale. Data of 201 respondents were analyzed. Job demand was inversely associated with MCS (p = .05) and PCS (p = .049); job control was directly associated with PCS (p < .001) and MCS (p = .024). A high positivity scale score and high decision latitude score predicted high MCS and PCS. High job demand score predicted low MCS and PCS scores. Reduced job stressors and enhanced positive attitudes can improve HCWs' health-related quality of life.

Voriconazole treatment in adults and children with hematological diseases: can it be used without measurement of plasma concentration?

Indication and timing of trough plasma-voriconazole (VCZ)-concentration (t-PVC) measurement during VCZ treatment is a debated issue. Patterns of t-PVC were prospectively evaluated in pediatric (50 courses) and adult (95 courses) hematologic patients. Efficacy patterns were defined: adequate, t-PVC always ≥1 mcg/ml; borderline, at least one t-PVC measurement <1 mcg/ml but median value of the measurements ≥1 mcg/ml; inadequate, median value of the measurements <1 mcg/ml. Toxicity patterns were defined: favorable, t-PVC always ≤5 mcg/ml; borderline, one or more t-PVC measurements >5 mcg/ml but median value of the measurements ≤5 mcg/ml; unfavorable, median value of the measurements >5 mcg/ml. In children and adults the mean t-PVCs were higher during intravenous treatments. The t-PVC efficacy pattern was adequate, borderline and inadequate in 48%, 12%, and 40% of courses, respectively, in children, and in 66.3%, 16.8%, and 16.8% of courses, respectively, in adults. Adequate efficacy pattern was more frequent in children with body weight above the median (≥25 kg) (OR 4.8; P = .011) and in adults with active hematological disease receiving intravenous therapy (OR 3.93; P = .006). Favorable toxicity pattern was more frequent in children receiving VCZ daily dosage below the median (<14 mg/kg) (OR 4.18; P = .027) and in adults with body weight below the median (<68 kg) (OR 0.22; P = .004). T-PVC measurement is generally needed, however, a non t-PVC guided approach may be considered in heavier adults receiving intravenous VCZ. The risk of supratherapeutic levels does not seem an absolute indication for t-PVC monitoring.

Carbapenem-resistant Klebsiella pneumoniae in high-risk haematological patients: factors favouring spread, risk factors and outcome of carbapenem-resistant Klebsiella pneumoniae bacteremias.

BACKGROUND: Carbapenem-resistant Klebsiella pneumoniae (CRKP) spread and infections in patients with haematological malignancies are a serious concern especially in endemic areas. Treatment failures and delay in appropriate therapy for CRKP infections are frequent and the mortality rate associated with CRKP bacteremia in neutropenic haematological patients is reported about 60%. METHODS: Haematological patients harboring CRKP hospitalized between February 2012 and May 2013 in an Italian Teaching hospital were examined. Conditions favouring CRKP spread in a haematological unit, risk factors for bacteremia in CRKP-carriers and for CRKP bacteremia-related death were evaluated in this observational retrospective study. RESULTS: CRKP was isolated in 22 patients, 14 (64%) had bacteremia. Control measures implementation, particularly the weekly rectal screening for CRKP performed in all hospitalized patients and contact precautions for CRKP-carriers and newly admitted patients until proved CRKP-negative, reduced significantly the CRKP spread (14 new carriers identified of 131 screened patients vs 5 of 242 after the intervention, p = 0.001). Fifty-eight percent of carriers developed CRKP bacteremia, and acute myeloid leukemia (AML) resulted independently associated with the bacteremia occurrence (p = 0.02). CRKP bacteremias developed mainly during neutropenia (86%) and in CRKP-carriers (79%). CRKP bacteremias were breakthrough in 10 cases (71%). Ten of 14 patient with CRKP bacteremias died (71%) and all had AML. The 70% of fatal bacteremias occurred in patients not yet recognized as CRKP-carriers and 80% were breakthrough. Initial adequate antibiotic therapy resulted the only independent factor able to protect against death (p = 0.02). CONCLUSIONS: The identification of CRKP-carriers is confirmed critical to prevent CRKP spread. AML patients colonized by CRKP resulted at high risk of CRKP-bacteremia and poor outcome and the adequacy of the initial antibiotic therapy may be effective to improve survival. To limit the increase of resistance, the extensive use of antibiotics active against CRKP should be avoided, but in the setting of high CRKP pressure and high-risk CRKP-colonized haematological patients, timely empiric antibiotic combinations active against CRKP could be suggested as treatment of febrile neutropenia.

Background and episodic breathlessness in advanced cancer patients followed at home.

BACKGROUND: The aim of this study was to assess the phenomenon of episodic breathlessness in advanced cancer patients followed by palliative care services at home. METHODS: A consecutive sample of patients with advanced cancer, admitted to home care for a period of six months, was surveyed. The presence of background breathlessness and episodic breathlessness, their intensity, and drugs used for their treatment were collected. Factors inducing episodic breathlessness, and its influence on daily activities were investigated. RESULTS: Three hundred forty-seven advanced cancer patients admitted to home palliative care were surveyed. The prevalence of breathlessness was 35.3%. The mean intensity of breathlessness was 3.8 (SD 1.96), out of a maximum score of 10 for worst imaginable. Sixty patients (49.2%) were receiving drugs for background breathlessness. In the multivariate analysis the risk of breathlessness increased with cardiovascular disease, chronic obstructive pulmonary disease, and lung cancer while it decreased in patients with a better performance status. The prevalence of episodic breathlessness in patients with background breathlessness was 79.5% and its mean intensity was 7.1 (SD 1.5, range 2-10). The mean duration of episodic breathlessness was 28.6 minutes (SD 47.1, range 1-300 minutes). Forty-three patients (44.3%) were receiving one or more drugs as needed. The majority of episodic breathlessness events were triggered by activity. Episodic breathlessness was interfering with daily activities in 65 patients (67%). Episodic breathlessness wasn't associated with any variable taken into consideration. CONCLUSION: This study showed that episodic breathlessness frequently occurs in advanced cancer patients admitted to home care, is severe in intensity, is triggered in most cases by activity, and is characterized by a short duration which requires rapid measures.

Tapentadol PR for Pain Syndromes in Real Life Patients with Hematological Malignancy.

BACKGROUND: More than 50% of oncohematological patients suffer from pain syndrome, mostly originating from the bone, which often include nociceptive and neuropathic complaints. Tapentadol, a recently available treatment option for cancer pain, exerts a dual analgesic mechanisms (opioid and noradrenergic), allowing for a high clinical efficacy as well as for a reduction in adverse events compared to traditional opioids. AIM: To explore the safety and efficacy of tapentadol as a suitable agent for the pain management in the setting of oncohematology. METHODS: Our observational study included 36 patients with basal pain intensity (NRS) ranging from 5 to 10. Tapentadol prolonged release (PR) was given at the initial dose of 50 mg BID and careful titrated according to the achieved pain control. RESULTS: Tapentadol PR was given at the dosages ranging from 200 and 260 mg/day after a careful titration, allowed for a clinically (-7 points NRS) remarkable reduction of pain intensity without any significant side effects. CONCLUSION: In oncohematological patients on pain, tapentadol PR was effective and well tolerated, so representing a suitable treatment option in this difficult setting.

Do the smoking intensity and duration, the years since quitting, the methodological quality and the year of publication of the studies affect the results of the meta-analysis on cigarette smoking and Acute Myeloid Leukemia (AML) in adults?

BACKGROUND: The aim was to perform a systematic review and meta-analysis on the relationship between tobacco smoking and the onset of acute myeloid leukemia (AML) in adults. METHODS: PubMed and Scopus databases were systematically searched. In the meta-analysis, random or fixed effects models were used according to the presence of heterogeneity. Study quality was assessed using the Newcastle-Ottawa Scale. RESULTS: Twenty-seven articles were included. Case-control and cohort meta-analyses show that current, ever and former smokers have a significant increased risk to develop AML compared to never smokers [current: OR=1.36 (1.11-1.66) and RR=1.52 (1.10-2.14); ever: OR=1.25 (1.14-1.38) and RR=1.45 (1.10-1.90); former: OR=1.21 (1.03-1.41) and RR=1.45 (1.08-1.94)]. Moreover, increasing smoking intensity and duration is associated with an increase of the risk, OR shift from 1.14 (1-20 pack/years) to 2.36 (>40 pack/years). DISCUSSION AND CONCLUSION: Smoking may have a significant role in AML onset in a multistep pathogenesis.
