The prevalence of unhealthy substance use (USU) among medical inpatients can vary, and prior research has not characterized the prevalence of USU among patients cared for by a teaching service (TS) and a nonteaching hospitalist service (NTHS). The objective of this study was to compare the prevalence of USU among patients cared for by a TS and an NTHS. We conducted a cross-sectional study from February to June 2009 at a community teaching hospital. Within 24 hours of admission, all eligible internal medicine admissions to the TS or NTHS were screened for USU, using the Alcohol Use Disorders Identification Test-Consumption and Drug Abuse Screening Test. Patients screening positive then underwent a diagnostic interview and blinded chart review to increase case finding and to assess whether each patient's admission was related to USU. There were 414 eligible and consenting patients out of 656 patients identified. Patients on the TS were younger and more likely to be current smokers, male, unmarried, non-white, and unemployed (p<.01 for all comparisons). TS patients were more likely to have evidence of USU (29.2% vs. 12.3%; p<.01). Among all admissions to the TS, 22.2% were deemed to be probably or possibly due to USU, as compared with only 3.7% of admissions to the NTHS (p<.01). Medical TSs care for a greater share of patients with USU as compared with an NTHS. These data highlight the need for expanded medical resident training in the diagnosis and management of USU.

BackgroundRetracted articles continue to be cited after retraction, and this could have consequences for the scientific community and general population alike. This study was conducted to analyse the association of retraction on citations received by retracted papers due to misconduct using two-time frames: during a postretraction period equivalent to the time the article had been in print before retraction; and during the total postretraction period.MethodsQuasiexperimental, pre–post evaluation study. A total of 304 retracted original articles and literature reviews indexed in MEDLINE fulfilled the inclusion criteria. Articles were required to have been published in a journal indexed in MEDLINE from January 2013 through December 2015 and been retracted between January 2014 and December 2016. The main outcome was the number of citations received before and after retraction. Results were broken down by journal quartile according to impact factor and the most cited papers during the preretraction period were specifically analysed.ResultsThere was an increase in postretraction citations when compared with citations received preretraction. There were some exceptions however: first, citations received by articles published in first-quartile journals decreased immediately after retraction (p<0.05), only to increase again after some time had elapsed; and second, postretraction citations decreased significantly in the case of articles that had received many citations before their retraction (p<0.05).ConclusionsThe results indicate that retraction of articles has no association on citations in the long term, since the retracted articles continue to be cited, thus circumventing their retraction.

Our study suggests that unhealthy substance use is more likely to be detected on a Teaching Service than on a Hospitalist Service.

Introduction:Delusional disorder is traditionally considered a less severe clinical entity than schizophrenia or schizoaffective disorder. From the dimensional approach to psychiatric diagnostic classification it might be necessary redefine the diagnostic classification of psychosis.Aim:To assess differences found in psychopathology, neuropsychology and functioning among schizophrenia, schizoaffective disorder and delusional disorder.Methods:59 patients were included in this study. 30 out of them presented a diagnostic of schizophrenia, 15 patients delusional disorder and 14 schizoaffective disorder. All of them were assessed through different scales including PANSS, GAF, SIX, SCIP and DKEFS Stroop. To compare the different groups ANOVA, Post hoc Bonferroni analysis and X2 test were carried out.Results:We found statistically significant differences regarding negative symptoms between patients with schizophrenia and delusional disorder, being those less intense and severe in the last ones. In that way, a inversely proportional trend regarding negative and positive PANNS subtypes between schizophrenia and delusional disorder was observed.Conclusions:In spite of the fact that the delusional disorder is considered less severe disease than other psychosis we only found a less degree of severity for negative symptoms. Further studies with greater sample size must be conducted.
