RESUMEN

Closed university buildings proved to be one of the main hot spots for virus transmission during pandemics. As shown during the COVID-19 pandemic, physical distancing is one of the most effective measures to limit such transmission. As universities prepare to manage in-class activities, students' adherence to physical distancing requirements is a priority topic. Unfortunately, while physical distancing in classrooms can be easily managed, the movement of students inside common spaces can pose high risk of close proximity. This paper provides an experimental analysis of unidirectional student movement inside a case-study university building to investigate how physical distancing requirements impact student movement and grouping behaviour. Results show general adherence with the minimum required physical distancing guidance, but spaces such as corridors pose higher risk of exposure than doorways. Doorway width, in combination with group behaviour, affect the students' capacity to keep the recommended physical distance. Furthermore, questionnaire results show that students report higher perceived vulnerability while moving along corridors. Evidence-based results can support decision-makers in understanding individuals' exposure to COVID-19 in universities and researchers in developing behavioural models in preparation of future outbreaks and pandemics.

RESUMEN

The sterile insect technique is used around the world to suppress or eradicate populations of Ceratitis capitata (Wiedemann) with successful results. It consists of inundative releases of sterile insects into a wide area to reduce reproduction in a field population of the same species. It is necessary to know the dispersion of the sterile males in the field in order to define the maximum distance between the release points that ensures the distribution of the sterile flies in the entire target area. The release methods may vary depending on the area to be covered and the resources available. Manual ground release requires less technology. The aim of this research was to estimate the ability of sterile males to survive and disperse in the field, in the two main areas of citrus production in Uruguay. A release of 20,000 sterile males of C. capitata TslV8 (-inv D53) was performed at the central point of each area defined for the trials. Around these points, a network of 54 Jackson traps baited with trimedlure was installed forming five concentric rings, which were placed on days 1, 3, 5, and 7 after the release and were removed at 24 h in all cases. The emergence rate, flight ability, dispersion, and longevity were estimated. The standard distances obtained by the regression models were 127 m and 131 m for Salto and San José respectively. In Salto, the traps had catches until the eighth day, and in San José, there were no catches after the sixth day.

RESUMEN

OBJECTIVE: Posttraumatic stress disorder (PTSD) is often difficult to treat, and many patients do not achieve full remission. Complementary and integrative health approaches, such as mindfulness meditation, are intended to be integrated with evidence-based treatment. This study examined the efficacy of mindfulness-based stress reduction (MBSR) in the treatment of PTSD in U.S. military veterans. METHODS: Veterans with a diagnosis of PTSD (N=214) were randomly assigned to either 90-minute group MBSR or present-centered group therapy (PCGT) for eight weeks. Follow-up assessments were obtained at baseline and weeks 3, 6, 9 (primary endpoint), and 16. RESULTS: Both the MBSR and PCGT groups achieved significant improvement in PTSD as measured by the Clinician-Administered PTSD Scale for DSM-IV (CAPS-IV), with no statistically significant differences between groups. However, compared with PCGT, the MBSR group showed a statistically significant improvement in PTSD on the self-reported PTSD Checklist for DSM-IV over the nine weeks. This difference was not maintained posttreatment, at week 16. Strengths of the study include its large sample size, multisite design, active control group, single-blind outcome ratings, fidelity monitoring, large minority representation, and randomized approach. The study was limited by its high attrition rate and low representation of women. CONCLUSION: Both MBSR and PCGT appear to have beneficial effects in treating PTSD in veterans, with greater improvement observed in self-reported PTSD symptoms in the MBSR group. No differences between groups were observed on the CAPS-IV scale.

RESUMEN

We evaluated whether the obesity-associated years of life lost (YLL) have decreased over calendar time. We implemented a meta-analysis including only studies with two or more serial body mass index (BMI) assessments at different calendar years. For each BMI category (normal weight: BMI 18.5 to <25 [reference]; overweight: BMI 25 to <30; grade 1 obesity: BMI 30 to <35; and grade 2-3 obesity: BMI ≥ 35), we estimated the YLL change between 1970 and 1990. Because of low sample sizes for African-American, results are reported on Caucasian. Among men aged ≤60 years YLL for grade 1 obesity increased by 0.72 years (P < 0.001) and by 1.02 years (P = 0.01) for grade 2-3 obesity. For men aged >60, YLL for grade 1 obesity decreased by 1.02 years (P < 0.001) and increased by 0.63 years for grade 2-3 obesity (P = 0.63). Among women aged ≤60, YLL for grade 1 obesity decreased by 4.21 years (P < 0.001) and by 4.97 years (P < 0.001) for grade 2-3 obesity. In women aged >60, YLL for grade 1 obesity decreased by 3.98 years (P < 0.001) and by 2.64 years (P = 0.001) for grade 2-3 obesity. Grade 1 obesity's association with decreased longevity has reduced for older Caucasian men. For Caucasian women, there is evidence of a decline in the obesity YLL association across all ages.

RESUMEN

A rapid rise in the number of tobacco users in Saudi Arabia has occurred in the past decade, particularly among the youth. This study identified socio-cultural determinants of tobacco use and explored possible approaches to prevent adolescents' tobacco use in Saudi Arabia. A cross-sectional survey was administered using a self-administered questionnaire for collecting information on risk and protective factors for tobacco use among middle school students. School selection was stratified by region, gender, and type (public or private). Of 1,186 7-9th grade students, 1,019 questionnaires were analyzed. Risk factors affecting tobacco use included all important others' perceptions; mother, sister, friend, teacher and important person's tobacco use; pressure to use tobacco from brother, sister, friend and important persons; easy access to tobacco and frequent skipping of classes. Protective factors for tobacco use included family's perception; friend, teacher and important person's tobacco use; parents' help; support from family, friends, and teachers; accessibility to tobacco; school performance and family income, father's education, and district of residence. The findings of this study show clear gender differences in social influences and attitudes towards tobacco use. Religious beliefs and access to tobacco products were significantly associated with attitudes towards tobacco use and future intention of use. Developing and implementing effective gender specific school-based tobacco prevention programs, strict reinforcement of tobacco control policies, and a focus on the overall social context of tobacco use are crucial for developing successful long-term tobacco prevention programs for adolescents.

RESUMEN

OBJECTIVE: To investigate 1-year change in financial capacity in relation to conversion from amnestic mild cognitive impairment (MCI) to dementia. METHODS: Seventy-six cognitively healthy older controls, 25 patients with amnestic MCI who converted to Alzheimer-type dementia during the study period (MCI converters), and 62 patients with MCI who did not convert to dementia (MCI nonconverters) were administered the Financial Capacity Instrument (FCI) at baseline and 1-year follow-up. Performance on the FCI domain and global scores was compared within and between groups using multivariate repeated-measures analyses. RESULTS: At baseline, controls performed better than MCI converters and nonconverters on almost all FCI domains and on both FCI total scores. MCI converters performed below nonconverters on domains of financial concepts, cash transactions, bank statement management, and bill payment and on both FCI total scores. At 1-year follow-up, MCI converters showed significantly greater decline than controls and MCI nonconverters for the domain of checkbook management and for both FCI total scores. The domain of bank statement management showed a strong trend. For both the checkbook and bank statement domains, MCI converters showed declines in procedural skills, such as calculating the correct balance in a checkbook register, but not in conceptual understanding of a checkbook or a bank statement. CONCLUSIONS: Declining financial skills are detectable in patients with mild cognitive impairment (MCI) in the year before their conversion to Alzheimer disease. Clinicians should proactively monitor patients with MCI for declining financial skills and advise patients and families about appropriate interventions.

RESUMEN

BACKGROUND: In gastric juice, high levels of the carcinoembryonic antigen (CEA) and the carbohydrate antigen 19-9 (CA 19-9) have been found to correlate with precancerous lesions and gastric cancer. So far, sampling of gastric juice has required upper endoscopy. In place of this invasive procedure, we investigated a new tool for the quantitation of tumor markers in gastric juice. MATERIALS AND METHODS: The study population consisted of healthy controls and consecutive subjects with suspected gastric cancer or dyspepsia/epigastric distress. Patients were asked to swallow a small gelatine capsule (14 mm in length and 5 mm in diameter) containing a pierced plastic cover and surrounding a piece of absorbent paper. The capsule was left in the gastric cavity for 60 min to allow saturation of the absorbent paper with gastric juice. A 45-50 cm length of nylon thread connected to the inner capsule was used to remove the device from the gastric cavity. After processing the absorbent paper for radioimmunoassay, CEA and CA 19-9 levels were correlated to the findings of upper endoscopy and biopsies of gastric mucosa or suspected lesions. RESULTS: The endogastric capsule did not cause any side-effects and 62 participants were fully compliant to the procedure. Assessable gastric juice samples were taken from 23 patients with gastric cancer, 15 patients with intestinal metaplasia or dysplasia, 12 patients with gastritis and 12 controls without gastric diseases. In the 12 samples of gastric juice from control patients, mean values of CEA and CA 19-9 were 1.1 +/- 0.9 ng/ml and 16 +/- 7.5 ng/ml, respectively. The mean levels of both markers were found to increase according to the severity of gastric lesions and in patients with cancer, mean CEA and CA 19-9 levels were 513 +/- 627 ng/ml and 545 +/- 510 ng/ml, respectively. Patients with precancerous lesions and cancer showed higher levels of CEA and CA 19-9 than patients with normal findings or gastritis (P <0.001). CONCLUSIONS: The endogastric capsule is a simple, non-invasive tool for the measurement of CEA and CA 19-9 levels in gastric juice. These values may discriminate between normal or minor pathologic changes and precancerous lesions or carcinomas. Further investigations are warranted, since this may represent a new method for gastric cancer screening.

RESUMEN

BACKGROUND: Currently, there is no instrument that provides an accurate and simple method of monitoring pressure ulcer healing in clinical practice. This article reports the two studies that were conducted to assess the validity of the Pressure Ulcer Scale for Healing (PUSH) as a tool to monitor healing of stage II-IV pressure ulcers. METHODS: Subjects in both studies (N = 103 and N = 269) were elderly (mean Study 1, 75 years, mean Study 2, 80 years), and the majority were women (Study 1, 51%, Study 2, 70%). Study data were extracted from patients' permanent records. RESULTS: Principal components analysis confirmed that the PUSH tool accounted for 58% to 74% of the wound healing variance over a 10-week period in Study 1 and 40% to 57% of the wound healing variance over a 12-week period in Study 2. In addition, multiple regression analysis, used to measure the sensitivity of the model to total healing, showed PUSH accounted for 39% of the variance in 6 weeks and 31% of the variance over 12 weeks (p <.001; Studies 1 and 2, respectively). CONCLUSIONS: Data from these two studies confirmed that the PUSH tool, with the components of length times width, exudate amount, and tissue type, is a valid and sensitive measure of pressure ulcer healing. It is a practical approach that provides clinically valid data regarding pressure ulcer healing. Further testing is needed to confirm these findings.

RESUMEN

A phase III, randomized, double-blind, multi-institutional vaccinia melanoma oncolysate (VMO) trial was performed for patients with stage III (AJCC) melanoma. When compared with the control vaccinia virus (V) therapy, VMO therapy did not show clinical efficacy in the final analysis of data from this trial. However, the data did allude to significant therapeutic efficacy with VMO therapy if it had been compared with an observation arm. Therefore, a comparative overview statistical analysis was performed to identify the therapeutic efficacy of VMO. This review compares VMO results with data from the treatment and observation arms of other prominent randomized anti-melanoma biologic trials (i.e., ECOG EST 1684; SWOG, IFN-gamma (J. Natl. Cancer Inst. 87 (1995) 1710); WHO IFN-alfa-2a (ASCO 14 (1995) 410); Mayo IFN-alfa-2a (J. Clin. Oncol. 13 (1995) 2776); French IFN-alfa-2a (ASCO 15 (1996) 437). The analysis was carried out comparing the disease-free interval (DFI) and overall survival (OS). The analysis shows that the VMO results are fairly comparable to the results of the treatment arms from the ECOG and Mayo trials at the 5-year mark; percent DFI 0.37, 0.37, and 0.4, percent OS 0.48, 0.46, 0.47, respectively. In some cases, VMO DFI is superior to the observation arms from other studies; ECOG, Mayo, and WHO; 0.37 versus 0.26, 0.3, 0.27 (4 years), respectively. These comparative results suggest that the vaccinia arm is not a true observation arm in the VMO trial, and the VMO could have shown an enhanced efficacy had the trial included a no-treatment observation control arm.

RESUMEN

As individuals with significant functional deficits are discharged earlier from the hospital, health care professionals are challenged to develop cost-effective intervention programmes that will assist family members to manage caregiving problems in the home. The literature suggests that social problem-solving can positively influence the physical and psychological well-being of individuals. This paper describes a social problem-solving training procedure provided primarily by telephone to assist family caregivers to manage caregiving issues in the home.

RESUMEN

OBJECTIVE: We previously reported the resolution of syringohydromyelia without cerebellar tonsillar ectopia in five patients after posterior fossa decompression of the so-called Chiari 0 malformation. A sixth patient is described. In this study, the anatomy of the posterior fossa is analyzed using radiological imaging, enabling features of the posterior fossa in this uncommon subgroup of children to be characterized. METHODS: Multiple measurements were made on magnetic resonance imaging studies in six children with Chiari 0 malformation to determine the position of the brainstem relative to the foramen magnum. Fifty children with normal magnetic resonance imaging studies of the brain were used as controls. RESULTS: All children with a Chiari 0 malformation were found to have the following positive results: obices that were located more than 2 standard deviations below normal, an increase in the anteroposterior midsagittal distance of the spinomedullary junction at the level of the foramen magnum, an increase in the angle between the floor of the fourth ventricle and clivus, and an increase in the anteroposterior midsagittal distance of the foramen magnum. CONCLUSION: The findings of this study suggest that the contents of the posterior fossa are indeed compromised and/or distorted in patients with syringohydromyelia but no tonsillar ectopia. In this group, the brainstem was caudally displaced more than 3 standard deviations below normal.

RESUMEN

PURPOSE:Severe abdominal pain secondary to chronic pancreatitis is often multifactorial in origin. Lateral pancreaticojejunostomy (LPJ) is currently the accepted surgical treatment of choice when the main pancreatic duct is dilated. Chemical ablation of the celiac plexus for the treatment of intractable pain in chronic pancreatitis has been used without clear benefit. The aim of this study is to compare treatment outcomes of 2 groups of patients with the diagnosis of chronic pancreatitis and intractable abdominal pain (LPJ alone versus LPJ with intraoperative alcohol celiac ablation).Between 1994 and 1997, 34 patients underwent LPJ to control intractable pain secondary to chronic pancreatitis. These patients were divided into 2 groups, group 1 was LPJ only (16 patients) and group 2 was LPJ and intraoperative celiac ablation with 50% absolute alcohol (18 patients). Preoperative diagnosis and treatment criteria were similar for both groups. The clinical characteristics and outcome of both groups were retrospectively analyzed. Fisher exact test was used for statistical analysis.Demographic characteristics were similar in both groups. Pain control at short- and long-term follow-up was significantly improved in group 2 compared with group 1 (p < 0.035).Intraoperative celiac ablation in addition to LPJ appears to have a better response than does LPJ alone. Even though the number of patients is small, these results provide a basis for pursuing a prospective, randomized study to definitively answer this question.

RESUMEN

BACKGROUND: A significant correlation exists between disability and the volume of black holes (BHL VOL), defined as hypointense lesions on T1-weighted cranial magnetic resonance imaging. A consistent correlation has also been reported between urinary myelin basic protein-like material (MBPLM) and the transition toward secondary progression (SP) from relapsing-remitting (RR) multiple sclerosis (MS). OBJECTIVE: To improve the management of MS through a noninvasive and cost-effective test for monitoring disease activity or disease status. DESIGN AND METHODS: From 662 patients with MS (86 with RR MS, 259 with SP MS without continued attacks, and 317 with SP MS with continued attacks), 24-hour urine samples were obtained at enrollment in the phase 3 Linomide (roquinimex) drug study. The urine specimens were analyzed for MBPLM and correlated with clinical features and findings on cranial magnetic resonance imaging. RESULTS: Significant but weak correlations existed between urinary MBPLM and BHL VOL in all patients with MS (r = 0.114, P =.003; n = 662), patients with SP MS without attacks (r = 0.185, P =.003; n = 259), and all patients with SP MS (r = 0.122, P =.003; n = 576). No significant correlations were detected in the RR MS group or any of the disease groups or subgroups whose Expanded Disability Status Scale score was 5.0 or lower. In subgroup analysis, the most significant correlation was detected between urinary MBPLM after adjustment for creatinine and BHL VOL in patients with SP MS with an Expanded Disability Status Scale score of 5.5 or higher but without continued relapses (r = 0.417, P<.001; n = 138). CONCLUSIONS: In patients with advanced SP MS, urinary MBPLM may possibly serve as an indicator of failed remission and axonal damage. Urinary MBPLM correlates with disease status in MS, especially the transition of RR MS to SP MS with advancing disability.

RESUMEN

BACKGROUND: Body composition and resting energy expenditure (REE) have not been examined longitudinally during puberty. OBJECTIVE: The purpose of this longitudinal study was to examine the influence of pubertal maturation on REE relative to body composition in African American and white children. DESIGN: The study included 92 white and 64 African American children (mean age at baseline: 8.3 and 7.9 y, respectively) from Birmingham, AL. The children had 2-5 annual measurements of fat mass (FM), lean mass (LM), and REE. The Tanner stages of the children ranged from 1 to 5. Mixed-model repeated-measures analyses were used to test the change in REE relative to body composition with increasing Tanner stage among ethnic and sex groups. RESULTS: LM increased from Tanner stage 1 to subsequent stages. FM relative to LM decreased from Tanner stage 1 to stages 3, 4, and 5 but not from stage 1 to stage 2. The African American children had relatively higher limb LM and lower trunk LM than did the white children. REE declined with Tanner stage after adjustment for ethnicity, sex, FM, and LM. This decline was significant from Tanner stage 1 to stages 3, 4, and 5 but not to Tanner stage 2. After adjustment for age, Tanner stage, FM, and LM or LM distribution, REE was significantly higher in white than in African American children (by approximately 250 kJ/d). CONCLUSION: In a large sample of children at various Tanner stages, we found an ethnic difference in REE after adjustment for age, Tanner stage, FM, and LM that was not explained by the difference in LM distribution.

RESUMEN

OBJECTIVE: To determine the factors predictive of damage in a multiethnic (Hispanic, African American, and Caucasian) LUMINA (lupus in minority populations, nature versus nurture) cohort of patients with systemic lupus erythematosus (SLE) with disease duration of < or =5 years at enrollment (T0). METHODS: Variables (socioeconomic/demographic, clinical, immunologic, immunogenetic, behavioral, and psychological) were measured at T0 and annually thereafter. Disease damage was measured with the Systemic Lupus International Collaborating Clinics Damage Index (SDI), and disease activity was measured with the Systemic Lupus Activity Measure. The relationship between the different variables and the SDI at the last visit (TL) was examined (mean followup from diagnosis to TL 61 months; adjusted for disease duration). Poisson regression was used to identify the independent association between the different variables and SDI scores at TL. RESULTS: Seventy-two Hispanics, 104 African Americans, and 82 Caucasians were included. One-half of patients had not accrued any damage. Caucasians had the lowest SDI scores at T0, and Hispanics had the highest scores at TL. Renal damage occurred more frequently among Hispanics and African Americans, while integument damage was more frequent among African Americans. Neuropsychiatric (20%), renal (16%), and ocular (15%) damage occurred most frequently among all patients. Independent predictors of SDI at TL were age, corticosteroid use (maximum dose at T0), number of American College of Rheumatology (ACR) criteria met, disease activity, and abnormal illness-related behaviors. Other variables were less consistently associated with damage accrual (poverty in African Americans, lack of HLA-DRB1*0301 in Hispanics, presence of HLA-DQB1*0201 and acute onset of SLE in Caucasians). CONCLUSION: Damage in SLE occurs from the outset in some, but not all, patients; Hispanics accrue damage more rapidly. Disease factors (corticosteroid use, number of ACR criteria met, disease activity, and acute-onset type) are important, but age and abnormal illness-related behaviors also contribute to overall damage in SLE.

RESUMEN

This study was designed to assess the perceived optimal profiles of African Americans versus white Americans. A survey was conducted using profile silhouettes of 30 African American and 30 white patients, ranging in age from 7 to 17 years. Twenty white orthodontists, 18 African American orthodontists, 20 white laypersons, and 20 African American laypersons evaluated the profiles. The preference of each rater for each of the 60 profiles was scored on an attached visual analog scale. Eighteen cephalometric variables were measured for each profile, and statistical analyses were performed on the profiles that had a mean rating of 60 or greater from an analog scale of 0 to 100. The results show the following 6 cephalometric variables were significant: Z-angle, skeletal convexity at A-point, upper lip prominence, lower lip prominence, nasomental angle, and mentolabial sulcus. All raters preferred the African American sample to have a greater profile convexity than they preferred for the white sample. The raters preferred the African American sample with upper and lower lips that were more prominent compared with the white sample. However, only the choice of the African American orthodontists for the African American sample was significantly different for this parameter. The white orthodontists gave the highest mean scores for the profile chosen, whereas the African American laypersons gave the lowest scores.

RESUMEN

OBJECTIVES: To investigate the consistency of physician judgments of treatment consent capacity (competency) for patients with Alzheimer's disease (AD) when specific legal standards (LS) for competency are used, and to identify the LS most clinically relevant to experienced physicians. DESIGN: Control and AD patient participants were videotaped being administered a measure of capacity to consent to medical treatment. Study physicians viewed videotapes of these assessments individually and made competency judgments for each participant under different LS followed by their own personal judgment of competency. SETTING: A university medical center. PARTICIPANTS: Participants were 10 older controls and 21 patients with AD (10 with mild and 11 with moderate AD). Five physicians with experience assessing the competency of AD patients were recruited from the geriatric psychiatry, geriatric medicine, and neurology services of a university medical center. MEASUREMENTS: The 31 participants were videotaped performing on a measure of treatment consent capacity (Capacity to Consent to Treatment Instrument) (CCTI). The CCTI consists of two clinical vignettes (A-neoplasm and B-cardiac) that test competency under five LS. Vignette A and B assessments were videotaped separately for each participant (total videotapes for sample = 62). Each study physician viewed each videotaped vignette individually, made judgments under each of the LS (competent or incompetent), and then made his/her own personal competency judgment. Physicians were blinded to participant diagnosis. Within participant group, consistency of physician judgments was evaluated across LS and personal judgments using percentage agreement and kappa. Agreement between personal and LS judgments for the AD group was evaluated for each physician using logistic regression. RESULTS: As expected, physicians as a group generally demonstrated very high percentage agreement in their LS and personal competency judgments for the control group. For the AD group, mean percentage judgment agreement among physicians ranged from a high of 84% (LS1) (evidencing a treatment choice) to a low of 67% (LS3) (appreciating consequences of treatment choice). Mean percentage agreement for personal competency judgments was 76%. For the AD sample, kappa analyses for physicians as a group demonstrated significant agreement not attributable to chance for LS5 (understanding treatment situation/choices) (k = 0.57, P = .001), LS4 (providing rational reasons for treatment choice) (k = 0.39, P = .04), and also for personal judgments (k = 0.48, P = .009). Analysis of LS judgment agreement within physician indicated that physicians applied the LS as discrete standards. Within-physician and for the AD sample, personal competency judgments were associated significantly with judgments on LS5 (P = .001), LS4 (P = .004), and LS3 (P < .04). CONCLUSIONS: Experienced physicians demonstrated significant agreement assessing competency in AD patients when judgments were based upon specific legal standards. Personal competency judgments of physicians showed a substantially higher level of agreement than found in a previous study, where specific LS were not used. These results suggest that consistency of physician competency judgments can be enhanced if they are guided by knowledge of specific LS. Physicians' personal competency judgments were most closely associated with comprehension and reasoning LS, the most conservative and clinically appropriate standards for deciding competency.

RESUMEN

PURPOSE: To determine key characteristics or factors associated with rehabilitation participation during the first year following discharge for persons with either traumatic brain injury (TBI), spinal cord injury (SCI), intra-articular fracture (IAF), or burn injury (BURNS). METHOD: Medical records and longitudinal survey [telephone questionnaire] data were collected for persons in the four injury groups and analyzed using hierarchical logistic regression procedures for each domain of factors. RESULTS: The only significant predictors with odds ratios greater than one were those for vocational rehabilitation participation. TBI patients lacking private insurance were 2.6 times more likely to participate in vocational rehabilitation; older SCI and TBI patients are about twice as likely to participate in vocational rehabilitation; and finally those with IAF or BURNS who are married at 12 months post discharge are 11.5 and 4.4 times respectively more likely to participate in vocational rehabilitation. CONCLUSION: Those lacking valuable socio-economic resources, such as private insurance (for TBI) and social support systems provided by marriage (for BURNS and IAF patients) are much more likely to be referred to vocational rehabilitation. This is true for older SCI and TBI patients as well. Lacking such resources, patients may be viewed by referral agents as less likely to benefit from in or outpatient rehabilitation.

RESUMEN

Radiographic studies of methotrexate (MTX) treated and minocycline treated patients with rheumatoid arthritis (RA) are reviewed. A formal metaanalysis of publications of RA treated with MTX was undertaken at the time when MTX was used for patients with established RA. Thus the conclusions of that metaanalysis may not be applicable to patients treated with MTX earlier in the course of their disease. On the other hand, there are no sufficient data to conduct a formal metaanalysis of patients with RA treated with minocycline.
