Bone mineral density in adults with Down syndrome.

This study analyzed data of bone mineral density (BMD) from a large cohort of adults with Down syndrome (DS). BMD was found to decrease with age more rapidly in these subjects than in the general population, exposing adults with DS to an increased risk of osteoporosis and bone fracture. INTRODUCTION: Down syndrome (DS) in adulthood presents with a high prevalence of osteoporosis. However, in DS, bone mineral density (BMD) can be underestimated due to short stature. Furthermore, the rate of age-related decline in BMD and its association with gender in DS has been rarely evaluated or compared with the general population. The present study is aimed at assessing the variation of BMD with age and gender in a sample of adults with DS and to compare these data with those of the general population, after adjusting for anthropometric differences. METHODS: Adults with DS, aged 18 or older, were assessed dual-energy-X-ray-absorptiometry (DXA) at the femoral neck and at the lumbar spine. They were compared with the general population enrolled in the National Health and Nutrition Examination Survey (NHANES) 2009-2010 dataset. Bone mineral apparent density (BMAD) was calculated for each individual. RESULTS: DXA was evaluated in 234 subjects with DS (mean age 36.93 ± 11.83 years, ranging from 20 to 69 years; 50.4% females). In the lumbar spine both mean BMD (DS 0.880 ± 0.141 vs. NHANES 1.062 ± 0.167, p < 0.001) and BMAD (DS 0.138 ± 0.020 vs. NHANES 0.152 ± 0.020, p < 0.001) were significantly lower in the DS sample than in the NAHNES cohort. The same trend was observed at the femoral neck in both BMD (DS 0.658 ± 0.128 vs. NHANES 0.835 ± 0.137, p < 0.001) and BMAD (DS 0.151 ± 0.030 vs. NHANES 0.159 ± 0.028, p<0.001). Age was associated with lower femoral neck BMAD in both samples; importantly, this association was significantly stronger in the DS sample. In the lumbar spine region, no significant association between BMAD and age could be observed in both samples. CONCLUSIONS: Adults with DS have lower bone mineral density compared to the general population and they experience a steeper decline with age. Early screening programs are needed in DS population.

Smad7 positively regulates keratinocyte proliferation in psoriasis.

BACKGROUND: Transforming growth factor (TGF)-ß1 exerts inhibitory effects on keratinocyte proliferation. OBJECTIVES: To examine whether Smad7, a known inhibitor of TGF-ß1 signalling, is involved in psoriasis-associated keratinocyte hyperproliferation. METHODS: Smad7 was evaluated in skin sections of patients with psoriasis and healthy controls and in mice with Aldara-induced skin pathology by real-time polymerase chain reaction and immunohistochemistry. To assess whether Smad7 positively regulates in vivo keratinocyte growth, mice treated with Aldara received daily cutaneous administration of Smad7 antisense oligonucleotide (AS). Keratin (K)6 and K16, cell-cycle-associated factors, cell-cycle and cell proliferation were evaluated in HaCaT cells either treated with Smad7 AS or transfected with Smad7 plasmid and in mice given Smad7 AS. RESULTS: Smad7 was highly expressed in keratinocytes of patients with psoriasis and of mice treated with Aldara. In HaCaT cells, Smad7 knockdown inhibited cell growth, reduced K6 and K16 expression and promoted accumulation of cells in the S-phase of the cell cycle. Smad7-deficient keratinocytes exhibited reduced levels of CDC25A protein, a phosphatase that facilitates progression of cells through the S-phase, and hyperphosphorylation of eukaryotic initiation factor 2 (eIF2)α, a negative regulator of CDC25 protein translation. Consistently, Smad7 overexpression in HaCaT cells was followed by induction of K6 and K16 and increased cell proliferation. Topical application of Smad7 AS to Aldara-treated mice reduced epidermal thickness. CONCLUSIONS: Our data show that Smad7 is overexpressed in human and murine psoriasis and suggest a key role of this molecule in the control of keratinocyte proliferation.

Inequality in 30-day mortality and the wait for surgery after hip fracture: the impact of the regional health care evaluation program in Lazio (Italy).

INTERVENTIONS: that address inequalities in health care are a priority for public health research. We evaluated the impact of the Regional Health Care Evaluation Program in the Lazio region, which systematically calculates and publicly releases hospital performance data, on socioeconomic differences in the quality of healthcare for hip fracture. DESIGN: Retrospective cohort study. SETTING: and participants We identified, in the hospital information system, elderly patients hospitalized for hip fracture between 01 January 2006 and 31 December 2007 (period 1) and between 01 January 2009 and 30 November 2010 (period 2). MAIN OUTCOME MEASURES: We used multivariate regression models to test the association between socioeconomic position index (SEP, level I well-off to level III disadvantaged) and outcomes: mortality within 30 days of hospital arrival, median waiting time for surgery and proportion of interventions within 48 h. RESULTS: We studied 11 581 admissions. Lower SEP was associated with a higher risk of 30-day mortality in period 1 (relative risk (RR) = 1.42, P = 0.027), but not in period 2. Disadvantaged people were less likely to undergo intervention within 48 h than well-off persons in period 1 (level II: RR = 0.72, P < 0.001; level III: RR = 0.46, P < 0.001) and period 2 (level II: RR = 0.88, P = 0.037; level III: RR = 0.63, P < 0.001). We observed a higher probability of undergoing intervention within 48 h in period 2 compared with the period 1 for each socioeconomic level. CONCLUSION: This study suggests that a systematic evaluation of health outcome approach, including public disclosure of results, could reduce socioeconomic differences in healthcare through a general improvement in the quality of care.

Gender may be related to the side of the motor syndrome and cognition in idiopathic Parkinson's disease.

BACKGROUND: and Sex and cognitive profile may be related to the laterality of motor symptoms in idiopathic Parkinson's disease. INTRODUCTION: Parkinson's disease (PD) is well recognised as an inherently asymmetric disease with unilateral onset of motor symptoms. The laterality of motor symptoms may be linked to sex, clinical and demographic variables, and neuropsychological disorders. However, the available data are inconsistent. This study aimed to explore the potential association between the laterality of motor symptoms and clinical and demographic variables and deficits in specific cognitive domains. MATERIAL AND METHODS: We retrospectively recruited 97 participants with idiopathic PD without dementia; 60 presented motor symptoms on the left side and 37 on the right side. Both groups were comparable in terms of age, age at disease onset, disease duration, and severity of the neurological deficits according to the Unified Parkinson's Disease Rating Scale and the Hoehn and Yahr scale. RESULTS: Participants with left-side motor symptoms scored lower on the Schwab and England Activities of Daily Living scale. Our sample included more men than women (67% vs. 33%). Both sexes were not equally represented in the 2 groups: there were significantly more men than women in the group of patients with left-side motor symptoms (77% vs. 23%), whereas the percentages of men and women in the group of patients with right-side motor symptoms were similar (51% vs. 49%). Both groups performed similarly in all neuropsychological tasks, but women, independently of laterality, performed better than men in the naming task. CONCLUSION: We found a clear prevalence of men in the group of patients with left-side motor symptoms; this group also scored lower on the Schwab and England Scale. Female sex was predictive of better performance in the naming task. Sex should always be considered in disorders that cause asymmetric involvement of the brain, such as PD.

Socio-demographic differences in adherence to evidence-based drug therapy after hospital discharge from acute myocardial infarction: a population-based cohort study in Rome, Italy.

WHAT IS KNOWN AND OBJECTIVE: Adherence to evidence-based drug therapy after acute myocardial infarction has increased over the last decades, but is still unsatisfactory. Our objectives are to set out to analyse patterns of evidence-based drug therapy after acute myocardial infarction (AMI), and evaluating socio-demographic differences. METHODS: A cohort of 3920 AMI patients discharged from hospital in Rome (2006-2007) was selected. Drugs claimed during the 12 months after discharge were retrieved. Drug utilization was defined as density of use (boxes claimed/individual follow-up; chronic use = 6+ boxes/365 days) and therapeutic coverage, calculated through Defined Daily Doses (chronic use: ≥80% of individual follow-up). Patterns of use of single drugs and their combination were described. The association between poly-therapy and gender, age and socio-economic position (small-area composite index based on census data) was analysed through logistic regression, accounting for potential confounders. RESULTS AND DISCUSSION: Most patients used single drugs: 90·5% platelet aggregation inhibitors (antiplatelets), 60·0%ß-blockers, 78·1% agents acting on the renin-angiotensin system (ACEIs/ARBs), 77·8% HMG CoA reductase inhibitors (statins). Percentages of patients with ≥80% of therapeutic coverage were 81·9% for antiplatelets, 17·8% for ß-blockers, 64·4% for ACEIs/ARBs and 76·1% for statins. The multivariate analysis showed gender and age differences in adherence to poly-therapy (females: OR = 0·84; 95% CI 0·72-0·99; 71-80 years age-group: OR = 0·82; 95% CI 0·68-0·99). No differences were observed with respect to socio-economic position. WHAT IS NEW AND CONCLUSION: The availability of information systems offers the opportunity to monitor the quality of care and identify weaknesses in public health-care systems. Our results identify specific factors contributing to non-adherence and hence define areas for more targeted health-care interventions. Our results suggest that efforts to improve adherence should focus on women and older patients.

Role of the association of high-risk HPV identified by real-time PCR in cervical preneoplastic lesions.

OBJECTIVE: To evaluate the effects of infection in multiple types of high-risk human papilloma virus (HPV) in cervical preneoplastic lesions in patients undergoing colposcopy following a diagnosis of atypical squamous cells of unknown significance (ASCUS) and low-grade squamous intraepithelial (LSIL) cytology. MATERIALS AND METHODS: Between 2009 and 2010, 2,500 patients were recruited with a mean age of 35 +/- 5 years. Screening for cervical cancer was performed and in case of ASCUS and LSIL the patients underwent colposcopy. The tests for the detection and typing of viral DNA (HPV - DNA test) were performed on cervical swab with real-time PCR amplification. RESULTS: The prevalence of infection was 70% (1579/2256) in the patients recruited. In relation to the degree of preneoplastic lesions some high-risk HPV viral genotypes were identified: HPV 16 (319/1466), HPV 18 (164/1466), HPV 45 (76/1466), HPV 31 (215/1466), HPV 52 (145/1466), HPV 58 (55/1466) HPV 56 (79/1466), HPV 51 (110/1466), HPV 6(138/1466), HPV 11 (88/1466), HPV 42 (34/1466), HPV 53 (43/1466). In case of high-grade lesions of CIN (CIN2 and CIN3) a greater HPV co-infection was detected and in particular the association from 16 to 18 (70%), 16-33 (18%) and 16 to 52 (12%). CONCLUSIONS: Infection caused by the simultaneous presence of multiple HPV genotypes appears to be associated with a significantly increased risk of high-grade lesions of CIN or invasive cancer than the presence of single viral infections. The infection with multiple HPV types is a significant risk factor for high-grade lesions of CIN in women undergoing colposcopy for ASCUS cytology/LSIL. The use of real-time PCR has shown the ability not only to identify the different types of HPV, but also to monitor quantitatively the same over time, and during the study phase, to evaluate the sensitivity and specificity of the method in comparison with other techniques.

The role of hypertension, body mass index, and serum leptin levels in patients with endometrial hyperplasia during premenopausal period.

OBJECTIVES: to investigate whether body mass index (BMI), hypertension (HTN), diabetes, age, and physical activity can be considered risk factors for endometrial simple hyperplasia in premenopausal women. Furthermore this study was undertaken to determine whether serum concentration of leptin in patients with BMI>or= 30 kg / m2 with endometrial hyperplasia deviate from values in patients with normal endometrium. MATERIALS AND METHODS: The authors enrolled 167 hyperplasia cases and 282 controls. Demographic characteristics and data on age, diabetes, hypertension, BMI, physical activity, and anthropometric parameters were collected. Leptin concentration in serum was measured with immunoenzymatic test kit from IBL. Univariable and multivariable analysis were performed to verify the association among age, HTN, BMI, physical activity, diabetes, and the presence of uterine hyperplasia. Furthermore the authors evaluated the correlation between BMI and leptin level (with Pearson's linear correlation) in women with simple hyperplasia and in controls. RESULTS: The prevalence of hyperplasia found was 34.4%. The following factors were independently associated with increased risk of endometrial hyperplasia: HTN (odds ratio 3.19, 95% confidence interval 1.20-8.48, p<0.020) and BMI>or=30 Kg/m2 (odds ratio 6.43, 95% confidence interval 3.92-10.53, p<0.000). Mean leptin concentration in serum was higher in patients who had endometrial hyperplasia than in controls (p<0.005) and the leptin levels depended on BMI. CONCLUSIONS: The following are risk factors for endometrial hyperplasia in premenopausal women: BMI>or=30 kg/m2 and HTN (blood pressure>or=130/85 or in therapy). Leptin appears to participate in proliferative processes of the endometrium, depending on BMI. Current guidelines may need to be reconsidered.

Profiling hospital performance to monitor the quality of care: the case of COPD.

Comparative outcomes data are widely used to monitor quality of care in the cardiovascular area; little is available in the respiratory field. We applied validated methods to compare hospital outcomes for chronic obstructive pulmonary disease (COPD) exacerbation. From the hospital information system, we selected all hospital admissions for COPD exacerbation in Rome (for 2001-2005). Vital status within 30 days was obtained from the municipality mortality register. Each hospital was compared to a pool of hospitals with the lowest adjusted mortality rate (the benchmark). Age, sex and several potential clinical predictors were covariates in logistic regression analysis. 12,756 exacerbated COPD patients were analysed (mean age 74 yrs, 71% males). Diabetes, hypertension, ischaemic heart disease, heart failure and arrhythmia were the most common coexisting conditions. The average crude mortality in the benchmark group was 3.8%; in the remaining population it was 7.5% (range 5.2-17.2%). In comparison with the benchmark, the relative risk of 30-day mortality varied widely across the hospitals (range 1.5-5.9%). A large variability in 30-day mortality after COPD exacerbation exists even considering patients' characteristics. Although these results do not detect mechanisms related to worse outcomes, they may be useful to stimulate providers to revision and improvement of COPD care management.

Traumatic right atrial rupture bridge to definitive repair with extra-corporeal life support.

Cardiac injury secondary to non-penetrating trauma is more common than thought, albeit, the injury is usually minor and goes undiagnosed without significant sequelae in most cases. Blunt cardiac rupture is much rarer accounting for <0.05% of all trauma cases but lethal in most circumstances. We present a case report of a young trauma victim who presented with both right atrial rupture and traumatic atrial septal disruption (ASD) requiring extra-corporeal life support (ECLS) and surgical repair. Blunt cardiac trauma with chamber rupture and septal disruption is a devastating injury. Stopping the hemorrhage and using ECLS gave our patient time to stabilize before definitive management of her traumatic ASD.

Treatment of Strongyloides stercoralis hyperinfection-associated septic shock and acute respiratory distress syndrome with drotrecogin alfa (activated) in a renal transplant recipient.

We report a case of Strongyloides stercoralis hyperinfection syndrome in a renal transplant recipient complicated by septic shock, acute respiratory distress syndrome, and Klebsiella pneumoniae superinfection. The patient was treated successfully with drotrecogin alfa (activated), parenteral ivermectin, albendazole, and piperacillin/tazobactam. This outcome suggests that drotrecogin alfa (activated) may be useful therapy for transplant recipients who develop severe sepsis or septic shock secondary to potentially lethal opportunistic infections.

DIA-MCIS: an importance sampling network randomizer for network motif discovery and other topological observables in transcription networks.

MOTIVATION: Transcription networks, and other directed networks can be characterized by some topological observables (e.g. network motifs), that require a suitable randomized network ensemble, typically with the same degree sequences of the original ones. The commonly used algorithms sometimes have long convergence times, and sampling problems. We present here an alternative, based on a variant of the importance sampling Monte Carlo developed by (Chen et al.). AVAILABILITY: The algorithm is available at http://wwwteor.mi.infn.it/bassetti/downloads.html

Laterality in Parkinson's disease may predict motor and visual imagery abilities.

Experimental evidence suggests that motor imagery (MI) engages the same neural substrates supporting actual motor activities and is likely impaired when such substrates are damaged, as in Parkinson's disease (PD). MI intuitively relies on visual imagery (VI), because mental simulations of physical movements depend on the visual retrieval of these movements. Although VI is generally considered a right hemispheric function, the hemispheric dominance of MI is still in dispute. Disparities in sidedness of motor disturbances are a distinctive feature of PD, and recent findings indicate that such disparities may similarly characterize cognition. Specifically, the deficits observed may depend upon which hemisphere is principally involved. Essentially, MI and VI are cognitive tasks subject to differential impairment and reflecting the prevalence of hemispheric impairment in PD. Motor imagery (assessed by the Vividness of Motor Imagery Questionnaire [VMIQ]) and VI (assessed by the Vividness of Visual Imagery Questionnaire [VVIQ] and Test of Visual Imagery Control [TVIC]) were examined in patients with asymmetric PD and in healthy elderly control subjects (HC group). VMIQ scores were similar in PD laterality subsets and the HC group, but VVIQ scores were significantly lower in both PD groups compared with the HC group. TVIC scores were significantly lower in the presence of left motor (right hemispheric) impairment and were predictive of left motor (right hemispheric) impairment. We suspect that MI is strongly reliant on VI and that language may mediate these two functions, to the extent that both are evoked through verbal stimuli. Working memory, both visual and verbal, is also involved in MI and VI tasks. Without due attention to laterality of symptoms, any training incorporating MI and VI may not deliver expected outcomes in the setting of asymmetric PD symptomatology.

Influenza outbreaks and hospital bed occupancy in Rome (Italy): current management does not accommodate for seasonal variations in demand.

OBJECTIVE: Our goal was to assess how different hospital wards react to influenza epidemics, and whether related specialties cooperate in coping with winter bed crises. STUDY DESIGN: The Lazio Hospital Information System (HIS) dataset from July 1998 to June 2001 was used for the study. The HIS collects data on all hospital discharges. We considered diagnosis-related groups (DRG) as the reason for hospital stay and used DRG to classify admissions as influenza related or influenza unrelated. Time series analysis of daily bed occupancy in different specialty areas by influenza-related and influenza-unrelated cases was performed. Generalized additive models (GAMs) were used to take the effect of short-term and seasonal bed occupancy into account on influenza-related occupancy. RESULTS: Influenza-related bed occupancy ranges from 770 patients/day during the influenza season to 525 patients/day during the rest of the year. Daily occupancy by influenza-related cases represents 2.8% of total hospital occupancy and 7% of general medicine occupancy during the influenza season. When comparing the influenza season with the rest of the year, general medicine occupancy by influenza-related cases increases by 51% versus the 25-32% increase in other specialty wards. Little change in daily occupancy by influenza-unrelated cases was observed in all specialties when comparing the influenza season with the rest of the year. CONCLUSIONS: Hospital specialty wards react poorly and single handedly to a minor and predictable burden. Any winter bed crisis in the Lazio region is probably the result of defective management of available beds more than excess in demand.

Th17-type cytokines, IL-6 and TNF-α synergistically activate STAT3 and NF-kB to promote colorectal cancer cell growth.

Colorectal cancers (CRCs) often show a dense infiltrate of cytokine-producing immune/inflammatory cells. The exact contribution of each immune cell subset and cytokine in the activation of the intracellular pathways sustaining CRC cell growth is not understood. Herein, we isolate tumor-infiltrating leukocytes (TILs) and lamina propria mononuclear cells (LPMCs) from the tumor area and the macroscopically unaffected, adjacent, colonic mucosa of patients who underwent resection for sporadic CRC and show that the culture supernatants of TILs, but not of LPMCs, potently enhance the growth of human CRC cell lines through the activation of the oncogenic transcription factors signal transducer and activator of transcription 3 (STAT3) and nuclear factor-kappa B (NF-kB). Characterization of immune cell complexity of TILs and LPMCs reveals no differences in the percentages of T cells, natural killer T cells, natural killer (NK) cells, macrophages and B cells. However, T cells from TILs show a functional switch compared with those from LPMCs to produce large amounts of T helper type 17 (Th17)-related cytokines (that is, interleukin-17A (IL-17A), IL-17F, IL-21 and IL-22), tumor necrosis factor-α (TNF-α) and IL-6. Individual neutralization of IL-17A, IL-17F, IL-21, IL-22, TNF-α or IL-6 does not change TIL-derived supernatant-driven STAT3 and NF-kB activation, as well as their proproliferative effect in CRC cells. In contrast, simultaneous neutralization of both IL-17A and TNF-α, which abrogates NF-kB signaling, and IL-22 and IL-6, which abrogates STAT3 signaling, reduces the mitogenic effect of supernatants in CRC cells. IL-17A, IL-21, IL-22, TNF-α and IL-6 are also produced in excess in the early colonic lesions in a mouse model of sporadic CRC, associated with enhanced STAT3/NF-kB activation. Mice therapeutically given BP-1-102, an orally bioavailable compound targeting STAT3/NF-kB activation and cross-talk, exhibit reduced colon tumorigenesis and diminished expression of STAT3/NF-kB-activating cytokines in the neoplastic areas. These data suggest that strategies aimed at the cotargeting of STAT3/NF-kB activation and interaction between them might represent an attractive and novel approach to combat CRC.

Serum levels of 3alpha-androstanediol glucuronide in hirsute and non hirsute women.

This study has evaluated the behaviour of 3alpha-androstanediol glucuronide (3alpha-diol G) in 170 women of whom 85 had polycystic ovary syndrome (PCOS), 35 had idiopathic hirsutism (IH) and 50 had regular cycles (control group). Of the women with PCOS, 45 were hirsute (PCOS-H) and 40 were non hirsute (PCOS-NH). Women in the control group were not hirsute. Hirsutism was assessed by the same physician using the Ferriman-Gallway score. The body mass index (BMI) was estimated in all of the women. Plasma concentrations of 3alpha-diol G were elevated only in hirsute patients, both with PCOS and with IH. Even in PCOS-NH, concentrations of 3alpha-diol G were higher compared with controls (P < 0.001), but significantly lower (P < 0.001) than those of the PCOS-H and of the IH groups. The behaviour of 3alpha-diol G was not affected by BMI.

Coronary artery bypass graft surgery: socioeconomic inequalities in access and in 30 day mortality. A population-based study in Rome, Italy.

OBJECTIVES: To evaluate whether coronary artery bypass graft (CABG) surgery is equally provided among different socioeconomic status (SES) groups in accordance with need. To estimate the association between SES and mortality occurring 30 days after CABG surgery. DESIGN: Individual socioeconomic index assigned with respect to the characteristics of the census tract of residence (level I = highest SES; level IV = lowest SES). Comparison of age adjusted hospital admission rates of ischaemic heart disease (IHD) and CABG surgery among four SES groups. Retrospective cohort study of all patients who underwent CABG surgery during 1996-97. SETTING: Rome (2 685 890 inhabitants) and the seven cardiac surgery units in the city. PARTICIPANTS: All residents in Rome aged 35 years or more. A cohort of 1875 CABG patients aged 35 years or more. MAIN OUTCOME MEASURES: Age adjusted hospitalisation rates for CABG and IHD and rate of CABG per 100 IHD hospitalisations by SES group, taking level I as the reference group. Odds ratios of 30 day mortality after CABG surgery, adjusted for age, gender, illness severity at admission, and type of hospital where CABG was performed. RESULTS: People in the lowest SES level experienced an excess in the age adjusted IHD hospitalisation rates compared with the highest SES level (an excess of 57% among men, and of 94% among women), but the rate of CABG per 100 IHD hospitalisations was lower, among men, in the most socially disadvantaged level (8.9 CABG procedures per 100 IHD hospital admissions in level IV versus 14.1 in level I rate ratio= 0.63; 95% CI 0.44, 0.89). The most socially disadvantaged SES group experienced a higher risk of 30 day mortality after CABG surgery (8. 1%) than those in the highest SES group (4.8%); this excess in mortality was confirmed even when initial illness severity was taken into account (odds ratio= 2.89; 95% CI 1.44, 5.80). CONCLUSIONS: The universal coverage of the National Health Service in Italy does not guarantee equitable access to CABG surgery for IHD patients. Factors related to SES are likely to influence poor prognosis after CABG surgery.

Inequality in health: socioeconomic differentials in mortality in Rome, 1990-95.

STUDY OBJECTIVE: Population groups with a lower socioeconomic status (SES) have a greater risk of disease and mortality. The aim of this study was to investigate the relation between SES and mortality in the metropolitan area of Rome during the six year period 1990-1995, and to examine variations in mortality differentials between 1990-92 and 1993-95. DESIGN: Rome has a population of approximately 2,800,000, with 6100 census tracts (CTs). During the study period, 149,002 deaths occurred among residents. The cause-specific mortality rates were compared among four socioeconomic categories defined by a socioeconomic index, derived from characteristics of the CT of residence. MAIN RESULTS: Among men, total mortality and mortality for the major causes of death showed an inverse association with SES. Among 15-44 year old men, the strong positive association between total mortality and low SES was attributable to AIDS and overdose mortality. Among women, a positive association with lower SES was observed for stomach cancer, uterus cancer and cardiovascular disease, whereas mortality for lung and breast cancers was higher in the groups with higher SES. Comparing the periods 1990-92 and 1993-95, differences in total mortality between socioeconomic groups widened in both sexes. Increasing differences were observed for tuberculosis and lung cancer among men, and for uterus cancer, traffic accidents, and overdose mortality among women. CONCLUSIONS: The use of an area-based indicator of SES limits the interpretations of the findings. However, despite the possible limitations, these results suggest that social class differences in mortality in Rome are increasing. Time changes in lifestyle and in the prevalence of risk behaviours may produce differences in disease incidence. Moreover, inequalities in the access to medical care and in the quality of care may contribute to an increasing differentials in mortality.

Treatment of aggressive non-Hodgkin's lymphoma in elderly patients with thiotepa, Novantrone (mitoxantrone), vincristine, prednisone (TNOP).

The aging of the population and the increased incidence of non-Hodgkin's lymphoma will result in a large number of elderly patients with this disorder. Newer therapies will be required for this group of patients. This article reports a new therapy for elderly patients with diffuse aggressive non-Hodgkin's lymphoma. Patients were treated with TNOP (thiotepa 20 mg/m(2), mitoxantrone (Novantrone) 10 mg/m(2), vincristine (Oncovin) 1 mg/m(2) all on day 1 and prednisone 60 mg/m(2) on days 1 through 5 of a 21-day course. Twenty-six patients were enrolled on study. The patients' ages ranged from 66 years to 87 years, with a mean age of 75.5 years. Eleven patients had a partial response (42%) and 4 patients had a complete response (15%) for a total response of 57%. Eighty-one percent of patients survived 1 year and 54% survived for 2 years. The median survival was 26 months. Hematologic and nonhematologic toxicity was tolerable. We believe that TNOP is an excellent therapeutic option in this group of elderly patients, particularly in the palliative setting.
