Human chromosome 16 conservation in primates

A study was made of the organization of the chromosome orthologous to HSA16 in primates using a panel of 8 BAC probes spanning human chromosome 16. The probes were used in FISH experiments on great apes and on representatives of the Old World monkeys, New World monkeys, and lemurs. The domestic cat was used as an outgroup. The results indicate that 16p and 16q were separate chromosomes in a primate ancestor. They fused in a Catarrhini ancestor giving rise to the present day form found in HSA, great apes, and Old World monkeys. Several rearrangements were found in New World monkeys.     

PERCEPTUA.ND LEXICA.ACTORS IN A CAS.F LETTER-BY-LETTER READING

We report the case of a letter-by-letter reader (MJ) who showed normal processing of single letters and who could normally access the orthographic input lexicon when presented with letter names for aural recognition, or when allow ed enough tim e to process a visually presented letter string. However, MJ showed severe difficulties in simultaneously processing multiple letters and other simple visual stimuli. Furthermore, she does not have normal access to lexical orthographic representations and their meanings when stimuli are presented for too brief a time to allow for serial processing of the letter string. We found no evidence of (partial) lexical or semantic access without corresponding recognition of the letters in a word: No signs of implicit reading were observed w hen the input stimuli were controlled for the relevant visual features; “implicit reading” was only obtained under conditions that allowed sophisticated guessing. This pattern of results is interpreted as indicating that LBL reading (at least in MJ) results from damage to prelexical processing mechanisms. In MJ's case, the deficit reflects the degraded transfer of information from a normal visual processing system in the right hemisphere to a normal language processing system in the left hemisphere.

Human papillomavirus infection and cervical intraepithelial neoplasia in dialyzed patients

Human papillomavirus (HPV) infection is a risk factor for the development of cervical intraepithelial neoplasia (CIN). The incidence of certain cancers such as HPV-associated CIN is higher among dialysis patients than in the general population. In the literature there are few studies on the prevalence of HPV infection among dialyzed women and almost all of these studies concerned women with positive Pap smears. We enrolled 73 hemodialyzed women attending our center from January 2009 to December 2010; 29 denied informed consent and 44 underwent Pap tests and cervical curettage for HPV (mean age 62 ± 15 years). We found HPV positivity in 6 women (prevalence 13.6%). The prevalence of CIN in our sample was also 13.6% (6/44), 83.3% of which HPV related. Since cervical curettage for HPV is a cheap and easy to perform test with high specificity and sensitivity, we believe it is worthwhile including it in the pre-transplant workup of such women to lower the incidence of CIN in dialyzed patients and transplant recipients.     

Information and communication technology in chronic diseases: a patient’s opportunity

The increasing aging population, the prevalence of chronic diseases and rising costs have brought about some unique health care challenge to our global society. In response to the unmet health care needs, researchers are actively seeking for innovative solutions that target for (1) prevention of diseases and (2) personalized diagnosis and treatment. It is envisaged that by taking preventive measures for health monitoring, diagnosing and treating patients with a personalized approach at an early stage of disease development, health care will be more cost effective and sustainable. The authors provide an overview of the advancements in Information and Communication Technology (ICT), and explain how some innovative health solutions, through the use of Telemedicine, can now be an opportunity for patients and their family.     

Postremission therapy with repeated courses of high-dose cytarabine,idarubicin, and limited autologous stem cell support achieves a very good long-term outcome in European leukemia net favorable and intermediate-risk acute myeloid leukemia

Consolidation treatment in acute myeloid leukemia (AML) patients achieving complete remission (CR) is warranted. High-dose cytarabine (HDAC) is considered first choice in favorable risk and an option in intermediate-risk AML. However, its optimal dose and schedule, as well as the benefit of additional chemotherapy agents remain controversial. Herein, we report on the long-term outcome of consecutive unselected AML patients treated with repeated courses of HDAC, with the addition of idarubicin, followed by autologous peripheral blood stem cell (PBSC) support, in order to limit toxicity, according to Northern Italy Leukemia Group (NILG) AML-01/00 study (EUDRACT number 00400673). Among 338 patients consecutively diagnosed from 2001 to 2017 at our center, 148 with high-risk AML (adverse cytogenetic, isolated FLT3-internal tandem duplication mutation, refractory to first induction) were addressed to allogeneic stem cell transplant. All other cases, 186 patients (55%), median age 53 (range 19–75), were considered standard-risk and received the NILG AML-01/00 program. After achieving CR, patients were mobilized with cytarabine 8 g/sqm to collect autologous CD34+-PBSC and received three consolidation cycles with HDAC (20 g/sqm) plus idarubicin (20 mg/sqm) per cycle, followed by reinfusion of limited doses of CD34+ PBSC (1-2x106/kg). The program was completed by 160 (86%) patients. Toxicity was acceptable. Neutrophils recovered a median of 10 days. Treatment-related mortality was 3/160 (1.8%). After a median follow-up of 66.4 months, overall survival (OS) and relapse-free survival (RFS) at 5-years were 61.4% and 52.4%, respectively. Twenty-eight selected patients aged >65 had similar outcomes. According to European leukemia net-2010 classification, the OS and RFS at 5-years were 76.4% and 65% in favorable risk, without differences between molecular subgroups, 52.3% and 47.2% in Intermediate-I, 45.2% and 36.5% in Intermediate-II risk patients, respectively. In conclusion, consolidation including repeated courses of high dose cytarabine and idarubicin, with limited PBSC support, proved feasible and very effective in nonhigh risk patients. The incorporation of novel agents in its backbone may be tested to further improve patient's prognosis.     

A pilot study of nurse-led, home-based telecardiology for patients with chronic heart failure

We assessed the feasibility of home-based telecardiology for patients with chronic heart failure (CHF). Seventy-four CHF patients were enrolled into a programme of telephone follow-up and single-lead electrocardiography (ECG) monitoring. The patients transmitted their ECG data by fixed telephone line to a receiving station, where a nurse was available for an interactive teleconsultation. Patients were followed up for a mean (SD) of 307 (108) days; 1467 calls were analysed (213 ad hoc consultations and 1254 scheduled consultations). A total of 124 cardiovascular events were recorded. Modifications to therapy were suggested in response to 119 calls; hospital admissions were suggested for 13 patients, further investigations for 7 and a consultation with the patient's general practitioner for 13. No action was taken after 1330 calls. Twenty-two ECG abnormalities were recorded. In 63 patients receiving the beta-blocker carvedilol, the mean dosage increased from 36 to 42 mg. In the previous year there were 1.8 hospitalizations per patient, while in the follow-up period there were 0.2 hospitalizations per patient. Following up CHF patients using a nurse-led telecardiology programme seems to be feasible and useful.     

Clinicopathological features of primary cutaneous B-cell lymphomas from an academic regional hospital in central Italy: no evidence of Borrelia burgdorferi association

We reviewed the clinico-pathological features of 73 primary cutaneous B-cell lymphomas (PCBCLs), diagnosed in 10 years in Marche region in central Italy, which included 16 marginal zone lymphomas (MZL), 33 follicle centre lymphomas (FCL) and 24 diffuse large B cell lymphomas (DLBCL). We also investigated the presence of Borrelia burgdorferi in tissues by polymerase chain reaction. Differences in age, sex, location site, response to therapy, disease recurrence and 5-year disease-specific survival were observed among the 3 histological groups. Specific DNA sequences of Borrelia burgdorferi were not detected in any of the 73 cases of PCBCL. We conclude that PCBCLs in Marche region behave according to the literature data and do not seem to be associated with Borrelia burgdorferi. Additional investigations should be performed on other possible etiologies, at least in our geographical area.
