Changing patterns of cancer incidence in the early- and late-HAART periods: the Swiss HIV Cohort Study

The advent of highly active antiretroviral therapy (HAART) in 1996 led to a decrease in the incidence of Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), but not of other cancers, among people with HIV or AIDS (PWHA). It also led to marked increases in their life expectancy.

Very late coronary stent thrombosis of a newer-generation everolimus-eluting stent compared with early-generation drug-eluting stents: a prospective cohort study

Early-generation drug-eluting stents releasing sirolimus (SES) or paclitaxel (PES) are associated with increased risk of very late stent thrombosis occurring >1 year after stent implantation. It is unknown whether the risk of very late stent thrombosis persists with newer-generation everolimus-eluting stents (EES).

Early and late urodynamic assessment of ileal orthotopic bladder substitutes combined with an afferent tubular segment

PURPOSE: Limited information is available concerning changes in the urodynamic characteristics of orthotopic bladder substitutes with time. Therefore, we compared early and late urodynamic results in patients with an ileal orthotopic bladder substitute combined with an afferent tubular segment. MATERIALS AND METHODS: Of 139 patients surviving at least 5 years after cystoprostatectomy and ileal orthotopic bladder substitution with an afferent tubular segment 119 underwent urodynamic assessment, including 66 at a median of 9 months (early) and 77 at a median of 62 months (late). Of these patients 24 were assessed at each time point. Simultaneously all patients were asked to complete a bladder diary and questionnaire regarding continence for at least 3 days in the week preceding the urodynamic study. RESULTS: Urodynamic parameters were comparable in patients who were evaluated early and late postoperatively. In addition, median values at early and late urodynamic evaluation in the 24 patients with the 2 examinations showed no statistically significant differences for volume at first desire to void (300 vs 333 ml, p = 0.85), pressure at first desire to void (12 vs 13 cm H2O, p = 0.57), maximum cystometric capacity (450 vs 453 ml, p = 0.84), end filling pressure (19 vs 20 cm H2O, p = 0.17), reservoir compliance (25 vs 28 ml/cm H2O, p = 0.58) or post-void residual urine volume (5 vs 15 ml, p = 0.27). CONCLUSIONS: Urodynamic results after 5 years of living with an ileal orthotopic bladder substitute with an afferent tubular segment show grossly unchanged urodynamic characteristics. Patients maintain a reservoir capacity and micturition pattern consistent with a normal life-style. Reservoir pressure remained low, thereby protecting and preserving upper tract function. To achieve these results patients must be regularly followed, and the causes of bacteriuria, increased post-void residual urine and bladder outlet obstruction must be recognized and dealt with accordingly.

Early and late coronary stent thrombosis of sirolimus-eluting and paclitaxel-eluting stents in routine clinical practice: data from a large two-institutional cohort study

BACKGROUND: Stent thrombosis is a safety concern associated with use of drug-eluting stents. Little is known about occurrence of stent thrombosis more than 1 year after implantation of such stents. METHODS: Between April, 2002, and Dec, 2005, 8146 patients underwent percutaneous coronary intervention with sirolimus-eluting stents (SES; n=3823) or paclitaxel-eluting stents (PES; n=4323) at two academic hospitals. We assessed data from this group to ascertain the incidence, time course, and correlates of stent thrombosis, and the differences between early (0-30 days) and late (>30 days) stent thrombosis and between SES and PES. FINDINGS: Angiographically documented stent thrombosis occurred in 152 patients (incidence density 1.3 per 100 person-years; cumulative incidence at 3 years 2.9%). Early stent thrombosis was noted in 91 (60%) patients, and late stent thrombosis in 61 (40%) patients. Late stent thrombosis occurred steadily at a constant rate of 0.6% per year up to 3 years after stent implantation. Incidence of early stent thrombosis was similar for SES (1.1%) and PES (1.3%), but late stent thrombosis was more frequent with PES (1.8%) than with SES (1.4%; p=0.031). At the time of stent thrombosis, dual antiplatelet therapy was being taken by 87% (early) and 23% (late) of patients (p<0.0001). Independent predictors of overall stent thrombosis were acute coronary syndrome at presentation (hazard ratio 2.28, 95% CI 1.29-4.03) and diabetes (2.03, 1.07-3.83). INTERPRETATION: Late stent thrombosis was encountered steadily with no evidence of diminution up to 3 years of follow-up. Early and late stent thrombosis were observed with SES and with PES. Acute coronary syndrome at presentation and diabetes were independent predictors of stent thrombosis.

Differences in the EEG profiles of early and late responders to antipsychotic treatment in first-episode, drug-naive psychotic patients

The aim of this study was to search for differences in the EEG of first-episode, drug-naive patients having a schizophrenic syndrome which presented different time courses in response to antipsychotic treatment. Thirteen patients who fulfilled DSM-IV diagnosis for schizophrenia or schizophreniform disorder participated in this study. Before beginning antipsychotic treatment, the EEG was recorded. On the same day psychopathological ratings were assessed using the ADMDP system, and again after 7 and 28 days of treatment. The resting EEG (19 leads) was subject to spectral analysis involving power values for six frequency bands. The score for the schizophrenic syndrome was used to divide the patients into two groups: those who displayed a clinically meaningful improvement of this syndrome (reduction of more than 30%) after 7 days of treatment (early responders, ER) and those who showed this improvement after 28 days (late responders. LR). Analysis of variance for repeated measures between ER, LR and their matched controls with the 19 EEG leads yielded highly significant differences for the factor group in the alpha2 and beta2 frequency band. No difference was found between the slow-wave frequency bands. Compared to controls the LR group showed significantly higher alpha2 and beta2 power and, in comparison to the ER group, significantly higher alpha2 power. There were no significant differences between the ER and the control group. These findings point to differences in brain physiology between ER and LR. The implications for diagnosis and treatment are discussed.
