RESUMO

BACKGROUND: Healthcare-associated infections (HAIs), or nosocomial infections, represent a significant burden in terms of mortality, morbidity, length of stay and costs for patients hospitalized in intensive care units (ICUs). Surveillance systems are recommended by national and international institutions to gather data on HAIs in order to develop and evaluate interventions that reduce the risk of HAIs. STUDY DESIGN: Here we describe the methodology and the results of the surveillance system implemented in the ICU of the Policlinico Umberto I, a large teaching hospital in Rome, from April 2016 to October 2018. METHODS: The multimodal infection surveillance system integrates four different approaches: i) active surveillance of inpatients; ii) environmental microbiological surveillance; iii) surveillance of isolated microorganisms; and iv) behavioral surveillance of healthcare personnel. Data were collected on catheter-related bloodstream infections, ventilation-associated pneumonia, catheter-associated urinary tract infections and primary bloodstream infections that developed in patients after 48 h in the ICU. For environmental surveillance 14 points were selected for sampling (i.e. bed edges, medication carts, PC keyboards, sink faucets). The system of active surveillance of HAIs also included surveillance of microorganisms, consisting of the molecular genotyping of bacterial isolates by pulsed-field gel electrophoresis (PFGE). From 1 November 2016, monitoring of compliance with guidelines for hand hygiene (HH) and proper glove or gown use by healthcare personnel was included in the surveillance system. After the first six months (baseline phase), a multimodal intervention to improve adherence to guidelines by healthcare personnel was conducted with the ICU staff. RESULTS: Overall, 773 patients were included in the active surveillance. The overall incidence rate of device-related HAIs was 14.1 (95% CI: 12.2-16.3) per 1000 patient-days. The monthly device-related HAI incident rate showed a decreasing trend over time, with peaks of incidence becoming progressively lower. The most common bacterial isolates were Klebsiella pneumoniae (20.7%), Acinetobacter baumannii (17.2%), Pseudomonas aeruginosa (13.4%) and Staphylococcus aureus (5.4%). Acinetobacter baumannii and Klebsiella pneumoniae showed the highest proportion of isolates with a multidrug-resistant profile. A total of 819 environmental samples were collected, from which 305 bacterial isolates were retrieved. The most frequent bacterial isolates were Acinetobacter baumannii (27.2%), Staphylococcus aureus (12.1%), Enterococcus faecalis (11.1%), Klebsiella pneumoniae (5.2%) and Pseudomonas aeruginosa (4.7%). All Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae environmental isolates were at least multidrug-resistant. Genotyping showed a limited number of major PFGE patterns for both clinical and environmental isolates of Klebsiella pneumoniae and Acinetobacter baumannii. Behavioral compliance rates significantly improved from baseline to post-intervention phase. CONCLUSIONS: By integrating information gathered from active surveillance, environmental microbiological surveillance, surveillance of bacterial isolates and behavioral surveillance of healthcare personnel, the multimodal infection surveillance system returned a precise and detailed view of the infectious risk and microbial ecology of the ICU.

RESUMO

PURPOSE OF REVIEW: This review paper aims to provide a complete and updated overview on the clinical and pathophysiological aspects of Takotsubo syndrome (TTS), including prognosis, therapy, and the association with cerebrovascular conditions. RECENT FINDINGS: TTS is an increasingly recognized non-ischemic cardiomyopathy characterized by sudden, temporary weakening of the myocardium, of which the pathogenesis is unknown. Although pathogenesis of TTS remains unclear, a complex interaction between catecholamine-mediated stimulation, myocardial stunning, and subsequent stress-related myocardial dysfunction seems to be the main pathophysiological mechanism. Stroke is linked to TTS by a dual relationship since it may induce TTS by catecholamine release even if TTS itself also may be complicated by left ventricular thrombi leading to stroke. Given its possible complications, including the association with neurological diseases, both cardiologist and neurologists should be aware about TTS in order to diagnose it promptly and to initiate appropriate therapeutic measures.

RESUMO

A survey of arsenic and phosphorus in Pampean streams of Buenos Aires province was performed. Nitrates and ammonia were also determined. Stream water was sampled as well as stream sediment and filamentous algae. Results show that 32 streams exceeded the arsenic recommended guidelines for human consumption of 10 µg L-1 and six exceeded recommended values for aquatic organisms' protection of 50 µg L-1. The average concentration found was 36.54 µg L-1 and areas with more concentration of As are located in the southern region of the province, in streams that are tributaries of the Atlantic Ocean. Other regions with high As concentration are the Matanza River tributaries and the Arrecifes River tributaries. No differences of As concentration was found between stream sediments. Also, no seasonal pattern of As concentration was observed in one stream sampled during a year, but a positive correlation between As and the conductivity (p = 0.0002) and pH (p = 0.01) of the streams was found. Also, As bioaccumulation was detected for all the algae sampled, but no correlation between As accumulated and As in the stream water was found. Ammonia levels exceeded recommended guidelines for human consumption in the Argentinean law in 30 streams. The characterization performed in this study provides relevant information on the distribution of arsenic and its origin and mobility.

RESUMO

Background: The aim of our study was to assess how total intra-venous anaesthesia (TIVA) achieved by propofol and remifentanil continuous infusion could ensure proper success of the endobronchial laser therapy, in optimal conditions for the endoscopist, determining at the same time an adequate hypnosis and a good analgesia. Methods: We studied 50 patients (28M - 22F), ASA class I-IV, mean age 42 ± 32.5 years , subjected to laser endoscopy to repair tracheal stenosis. TIVA was performed in all patients, and spontaneous breathing was maintained. Results: 10.2% of patients experienced episodes of coughing during induction. The depth of the anaesthesia plan, monitored by BIS, was 55 ± 5. The awakening was fast in all patients, with an Aldrete score of 7.71 ± 1.14 at 1 minute and 9.31 ± 1.12 at 10 minutes. Conclusion: The results of this study allow us to state that the continuous infusion of propofol and remifentanil proved to be the gold standard in patients ASA I-II-III undergoing endobronchial laser therapy. The use of TIVA has also allowed to perform endoscopic intervention on patients who suffered from a significant decrease of both cardiac and respiratory functions.

RESUMO

Cervical dystonia is a syndrome characterized by anomalous postures and unintentional repetitive movements of the head and the neck. Aim of this study is to show the effectiveness of the combined treatment botulinum toxin-FKT through the use of a recent methodic of investigation, myoton, and of the classical clinical evaluations, such as Tsui and VAS scales. 15 patients (9 females, 6 males) have been selected. During the initial visit and in the following controls, performed every month, patients have been submitted to physiatric examination, clinical evaluation of the dystonia through the Tsui scale, clinical evaluation of the pain through the VAS scale, myometric evaluation. We obtained a statistical reduction of muscular tone values in passive elongation (t0=16,34±1,23) until 4 month (t4 =16,11±1,23), when we performed a second infiltration. After 4 months from the second infiltration (t8=15,99±1,11) value did not present more some statistical correlation and was necessary to perform a new infiltration. Values of elasticity, stiffness, Tsui and VAS scale followed the same course of the tone. Our study demonstrates that combined treatment botulinum toxin-FKT is effective. It emerges that if to the treatment with botulinum toxin follows a suitable FKT treatment, the effect of the drug lasts 4 months and not 3 months as described by the literature. Our study has underlined that using myometric measurement we can consider least changes in muscular tone, elasticity and stiffness; we have a broader view of the spastic muscle, and we can better plan appropriate rehabilitative care for each patient.

RESUMO

The word dysphagy was suggested by Nicolatopoulos (1907) and derives from the ancient Greek "duz", which means "difficulty" and "katapinein", which means "to swallow". Generally, the dysphagia is defined on the basis of its origin: oral, pharynx and oesophagus, otherwise by its mechanical or neurological aetiology. The symptoms are dependent on the nature of the lesions in the affected organs. The swallow is a complex motor sequence dependent on the coordinate contraction of the muscle of mouth, of larynx and of the oesophagus. The mechanical action of the swallow helps the liquid or solid food progression from mouth to stomach thanks to cooperation of 31 muscles and 5 cranial nerves and allows swallowing about 580 times approximately. The dysphagy in neurological diseases is mainly due to the following reasons. Increase of vascular cerebral disease, increase of population age and increase of road and work traumas. The difficulties in swallowing causes heavy social problems like meager diet, social isolation and worsening of quality of life. The speech rehabilitation requires the involvement of care givers through a re-educational program that takes place in two periods: the first of relaxation, and the second of restoration of phonodeglutition praxis.

RESUMO

Athletes who undergo strenuous exercise, especially in endurance sports, frequently use herbal supplements in order to have a better performance. In this review we try to find out if the most common herbal supplements (Echinacea, Rhodiola, Ginseng) are effective in the empowerment of performance or in the modulation of the immune system. It seems that the prevalent effect is adaptogenic rather than ergogenic, with a better tolerance of the exercise induced stress, related to enhancement of the whole immune system and decrease of the oxidative damage.

RESUMO

A new preparation of botulinum toxin type A called NT 201, free from complexing proteins, potentially with low antigenicity has been used in the therapy of spasticity in stroke patients. This was an open-label study reported the safety and the efficacy of one-year treatment with NT 201 evaluating the therapeutic effect on functional disability and on quality of life in upper limb spasticity after stroke. Patients received a botulinum toxin therapy in the upper injected intramuscularly. After inoculation, patients were submitted to a motor rehabilitation program for upper limb injected three times/week. Re-treatment was permitted at 12 weeks after the prior treatment. Safety assessment included evaluation of adverse events and efficacy was measured by Modified Ashworth Scale for spasticity (MAS), Spasm Frequency Score (SFS) for the daily spasms, and Disability Assessment Scale (DAS) for disability. Of 35 consecutive patients (13 women and 12 men) screened for study eligibility, 20 (6 women and 14 men) patients (mean age 63,4±7,03) were included in this study and were submitted to NT 201 therapy for one year. At the baseline, botulinum toxin dose in the upper limb ranged from 160 to 450U, whereas total dose in the last treatment administrated was reduced respect the first injections ranging from 120 to 350U. All the enrolled patients completed the year-long study and reported an improvement of clinical picture. MAS, was statistically (px003C;0,001) reduced in all muscles at T1 (mean score ±SD: 2.65±0.67) and T2 (mean score±SD: 2.55±0.60) in comparison to the baseline T0 (mean score±SD: 3.9 ±0.78). Significant reduction (px003C;0,001) from baseline T0 (mean score ±SD: 3.25±0.78) was also noted in SFS at T1 (mean score ±SD: 1.55±0.51) and T2 (mean score±SD :1.30±0.47). The DAS score showed a reduction of the T1score (mean score ±SD: 1.70±0.47) and T2 score (mean score ±SD: 1,40 ±0,50) respect to baseline T0 score (mean score ±SD: 2,65 ±0,48) statistically significant (p≤003C;0,001). No adverse effects were observed in these patients. NT 201 appeared to be an efficacious and well-tolerated long-term treatment option for patients with upper limb spasticity after stroke, obtaining a substantial improvement in functional disability, muscle hypertone, and daily spasms.

RESUMO

Antimuscarinic drugs are the first line pharmacotherapy for overactive bladder, but they are not always effective to achieve complete continence. Nevertheless in some patients urodynamic investigations reveal insufficient effects with continuing incontinence events even with dose optimization. The aim of this study is to evaluate the effect of association of Oxybutynin chloride, Trospium chloride and Solifenacin succinate administered orally for a minimum of 12 weeks in subjects with suprasacral spinal cord injury with urge-incontinence, urodynamic–proven neurogenic detrusor overactivity dysfunction and detrusor-external sphincter dyssynergia to improve level of continence, reduce the risks of urologic complications and enhance QOL. This study was a randomized, double blind, controlled, balanced-parallel-groups investigation of orally administed Oxybutynin in addition to Trospium chloride in the first group and Oxybutynin in addition to Solifenacin in the other group. A total of 12 patients with neurogenic detrusor overactivity and clean intermittent catheterization were allocated into two treatment groups: 5 mg tablet of Oxibutinin and 20 mg tablet of Trospium Chloride were administered respectively 3 times a day and 4 times a day in the first group (Group A). 5 mg tablet of Oxibutinin and 10 mg tablet of Solifenacin were administered respective 3 times a day and once daily in the second group (Group B). In both group of patients we found a significant decrease in incontinence episodes, with an improvement of bladder compliance, bladder capacity and volume voided. Side effects were higher in patients of group B, but in generally well tolerated. In conclusion, a combined antimuscarinic treatment might be a right option for patients affected by neurogenic bladder refractory to previous antimuscarinic monotherapy, and might slow down or delay other more invasive treatments.

RESUMO

Baclofen is now used in treatment of patients with severe spasticity secondary to neurological diseases through the direct infusion of the drug into the subarachnoid space with an implanted programmable pump. Among patients whose quality of life improved after the use of intrathecal systems, a very important role belongs to people with multiple sclerosis (MS): a disease that due to a great variety of symptoms and signs, seriously affects the activities of daily living. Among the clinical manifestations of MS are also found mental health problems including depression mood. The drugs most commonly offered, for treatment of depression in patients with MS, are selective serotonin reuptake inhibitors (SSRIs), reuptake inhibitors of serotonin and norepinephrine (SNRIs) and tricyclic antidepressants (TCA). Duloxetine presents a high affinity for transporters reuptake of serotonin and noradrenalin, and exerts its activity on both molecules. In addiction, Duloxetine has demonstrated very effective in treatment of depressive disorders of mood as demonstrated by scientific evidences about the utility of Duloxetine in the modulation of painful physical symptoms associated with depression and in treatment of pain associated with diabetic neuropathy. The purpose of our study is to evaluate the effects of antidepressant therapy with duloxetine, 60 mg/day in 7 patients with multiple sclerosis treated with intrathecal baclofen for spastic modulation of tone. The experience we gained, according to data from several multicenter trials confirmed the efficacy of Baclofen intrathecally administered, especially with regards to modulation of spasticity. Our study also showed, although the limitations of a small sample size still, a good clinical response to combined treatment Baclofen intrathecal/duloxetine 60 mg/day.

RESUMO

Bacterial numbers over refrigerated shelf-life were enumerated in high-temperature, short-time (HTST) commercially pasteurized fluid milk for 15 mo before and 15 mo after reducing pasteurization temperature from 79.4°C (175°F) [corrected] to 76.1°C (169°F). Total bacterial counts were measured in whole fat, 2% fat, and fat-free milk products on the day of processing as well as throughout refrigerated storage (6°C) at 7, 14, and 21 d postprocessing. Mean total bacterial counts were significantly lower immediately after processing as well as at 21 d postprocessing in samples pasteurized at 76.1°C versus samples pasteurized at 79.4°C. In addition to mean total bacterial counts, changes in bacterial numbers over time (i.e., bacterial growth) were analyzed and were lower during refrigerated storage of products pasteurized at the lower temperature. Lowering the pasteurization temperature for unflavored fluid milk processed in a commercial processing facility significantly reduced bacterial growth during refrigerated storage.

RESUMO

Abstract: Catheter dislocation and fracture with migration of central venous lines have been reported in the International literature. Catheter fracture with consequent migration has been observed in 0.5-3.0% and may either be consequent to catheter removal or it can occur spontane-ously. Our case report concerns the migration of a Hickman catheter connected to a venous port to the right atrium in a 61-year old patient. A literature up-to-date has been performed to assess the risk of port-a-cath positioning. The position of catheter tip is considered critical for the risk of migration, that is greater as higher the tip localization respect to the carina. The aim of our study is to underline the critical role of X-ray to visualize the exact location of the catheter tip, regard-less of the approach used for catheter positioning.

RESUMO

AIM: To determine whether the duration of respiratory distress symptoms in severe COVID-19 pneumonia affects the need for invasive mechanical ventilation and clinical outcomes. MATERIALS AND METHODS: An observational multicentre cohort study of patients hospitalised in five COVID-19-designated ICUs of the University Hospitals of Emilia-Romagna Region. Patients included were adults with pneumonia due to SARS-CoV-2 with PaO2/FiO2 ratio <300 mmHg, respiratory distress symptoms, and need for mechanical ventilation (invasive or non-invasive). Exclusion criteria were an uncertain time of respiratory distress, end-of-life decision, and mechanical respiratory support before hospital admission. MEASUREMENTS AND MAIN RESULTS: We analysed 171 patients stratified into tertiles according to respiratory distress duration (distress time, DT) before application of mechanical ventilation support. The rate of patients requiring invasive mechanical ventilation was significantly different (p < 0.001) among the tertiles: 17/57 patients in the shortest duration, 29/57 in the intermediate duration, and 40/57 in the longest duration. The respiratory distress time significantly increased the risk of invasive ventilation in the univariate analysis (OR 5.5 [CI 2.48-12.35], p = 0.003). Multivariable regression analysis confirmed this association (OR 10.7 [CI 2.89-39.41], p < 0.001). Clinical outcomes (mortality and hospital stay) did not show significant differences between DT tertiles. DISCUSSION: Albeit preliminary and retrospective, our data raised the hypothesis that the duration of respiratory distress symptoms may play a role in COVID-19 patients' need for invasive mechanical ventilation. Furthermore, our observations suggested that specific strategies may be directed towards identifying and managing early symptoms of respiratory distress, regardless of the levels of hypoxemia and the severity of the dyspnoea itself.

RESUMO

Analytical tools that accurately predict the performance of raw milk following its manufacture into commercial food products are of economic interest to the dairy industry. To evaluate the ability of currently applied raw milk microbiological tests to predict the quality of commercially pasteurized fluid milk products, samples of raw milk and 2% fat pasteurized milk were obtained from 4 New York State fluid milk processors for a 1-yr period. Raw milk samples were examined using a variety of tests commonly applied to raw milk, including somatic cell count, standard plate count, psychrotrophic bacteria count, ropy milk test, coliform count, preliminary incubation count, laboratory pasteurization count, and spore pasteurization count. Differential and selective media were used to identify groups of bacteria present in raw milk. Pasteurized milk samples were held at 6°C for 21 d and evaluated for standard plate count, coliform count, and sensory quality throughout shelf-life. Bacterial isolates from select raw and pasteurized milk tests were identified using 16S ribosomal DNA sequencing. Linear regression analysis of raw milk test results versus results reflecting pasteurized milk quality consistently showed low R(2) values (<0.45); the majority of R(2) values were <0.25, indicating small relationship between the results from the raw milk tests and results from tests used to evaluate pasteurized milk quality. Our findings suggest the need for new raw milk tests that measure the specific biological barriers that limit shelf-life and quality of fluid milk products.

RESUMO

BACKGROUND: There is considerable uncertainty as to the significance of a high sperm DNA fragmentation index (DFI) for achieving a successful pregnancy. METHODS: The sperm DFI of 124 patients undergoing 192 IVF cycles and of 96 patients undergoing 155 ICSI cycles was determined using the sperm chromatin structure assay on neat sperm. RESULTS: The rate of continuing pregnancies in ICSI cycles (but not in IVF cycles) showed significant negative correlation (r = -0.184, P = 0.022) with the DFI value. A threshold value of DFI which showed a significant difference (P = 0.005) in rate of continuing pregnancies between higher and lower DFI levels was found for ICSI cycles to be > or = 19%, but no such threshold was found for IVF cycles. However, if the threshold of > or = 30% was used for IVF cycles there was a non-significant lowering of the rates of continuing pregnancy and implantation at the higher DFI levels. DFI level had no effect on fertilization rate or on the percentage of embryos having more than 4 cells at Day 3 after fertilization. A high DFI level had a marked significant effect (P = 0.001) on implantation rate in ICSI cycles but not in IVF cycles. A significant positive correlation (r = 0.268, P = 0.001) between DFI and sperm midpiece defects was also noted in the ICSI patients. CONCLUSIONS: These observations may help to resolve the issues about how, and to what extent, sperm DNA damage impacts upon the success of IVF and ICSI procedures.

RESUMO

BACKGROUND: A key moderator of wound healing is oxygen. Wound healing is a dynamic and carefully orchestrated process involving blood cells, cytokines, parenchymal cells (i.e. fibroblasts and mesenchymal stem cells) and extracellular matrix reorganization. Human adipose derived stem cells as well as human fibroblasts produce soluble factors, exhibit diverse effects on inflammation and anti inflammation response and are involved in wound healing processes.Hyperbaric oxygen therapy is an effective adjunct treatment for ischemic disorders such as chronic infection or chronic wounds. In vitro effects of hyperbaric oxygen therapy on human cells were presented in many studies except for those on mono- and co-cultures of human adipose derived stem cells and fibroblasts. OBJECTIVE: The aim of this study was to investigate the effects of hyperbaric oxygen therapy on mono- and co-cultures of human adipose derived stem cells and fibroblasts. METHODS: Mono- and co-cultures from human adipose derived stem cells and fibroblasts were established. These cultures were exposed to hyperbaric oxygen therapy every 24 h for five consecutive days. Measuring experiments were performed on the first, third and fifth day. Therapy effects on the expression of VEGF, IL 6 and reactive oxygen species were investigated. RESULTS: After exposure to hyperbaric oxygen, cell culturess showed a significant increase in the expression of VEGF after 3 and 5 days. All cultures showed significantly reduced formation of reactive oxygen species throughout the experiments. The expression of IL-6 decreased during the experiment in mono-cultures of human adipose derived stem cells and co-cultures. In contrast, mono-cultures of human skin fibroblasts showed an overall significantly increased expression of IL-6. CONCLUSIONS: Hyperbaric oxygen therapy leads to immunmodulatory and proangiogenetic effects in a wound-like enviroment of adipose derived stem cells and fibroblasts.

RESUMO

BACKGROUND AND PURPOSE: Increasing evidence suggests a direct role of the TAR DNA-binding protein 43 (TDP-43) in neurodegeneration. Mutations in the TARDBP gene, which codes for TDP-43, have been recently reported in familial and sporadic amyotrophic lateral sclerosis (ALS) cases. METHODS: To further define the spectrum and frequency of TARDBP mutations, we present genetic analysis data on TARDBP in 314 ALS mainly Italian patients, including 16 subjects with non-SOD1 familial ALS. RESULTS: We identified four heterozygous missense mutations in five unrelated ALS patients (1.6%). Two of these mutations (p.G348C and p.A382T) were detected in carriers coming from families with an autosomal dominant transmission of different geographic origin (Belgian and Italian, respectively). The Belgian pedigree showed several affected members within five generations and with variable clinical features. Two novel mutations (p.G294V and p.G295S) were identified in two sporadic cases. CONCLUSION: The identification of five ALS patients carrying TARDBP alterations extends the spectrum of TARDBP mutations and supports the pathological role of TDP-43 in motor neurone disease. Our findings provide evidence that TARDBP mutations are not frequent in Italian sporadic ALS patients (1%); however, combined with the literature, our data further support TARDBP mutations as a relevant cause of familial ALS.

RESUMO

The aim of this trial was to evaluate the effects of alpha-lipoic acid (ALA) and gamma-linolenic acid (GLA) and the beneficial effect of physical exercise on positive sensory symptoms and neuropathic pain in patients with compressive radiculopathy syndrome from disc-nerve root conflict. Often these painful syndromes after the acute event, tend to recurr becoming subacute or chronic syndromes that become for the period of interest disabiling is an event very important in these cases proper prevention, based on a maintenance drug therapy and the strengthening exercises of paravertebral muscles, flexibility exercises on the spine and when needed on the reduction of body weight. In this Observational Cohort, two-arm trial, 203 patients were enrolled and divided into two groups, the first, ALA and GLA group, (n = 101) received oral dose of 600 mg of alpha-lipoic acid (ALA) and 360 mg of gamma-linolenic acid (GLA) and a rehabilitation program for six weeks, the second (n = 102) treated with only rehabilitation program. Patients were recruited at the centre of Physical Medicine and Rehabilitation, they underwent a physiatric examination at the primary outcome (t0) and secondary outcomes were recorded at monitoring visits scheduled at two weeks = t1, four weeks = t2, six weeks = t3, and at the same has been administered the following scale: VAS scale, SF-36, Oswestry Low Back Pain Disability Questionnaire, Aberdeen Back Pain Scale (ABPS), Revised Leeds Disability Questionnaire (LDQ), Roland and Morris Disability Questionnaire. Significant improvements was noted in the ALA and GLA group for paresthesia, stabbing and burning pain, as showed by VAS (Visual Analogue Scale), Oswestry Low Back Pain Disability Questionnaire, Aberdeen Low Back Pain Scale; also, improvements of quality of life has been noted, in the same group, as showed by SF-36, LDQ (Revised Leeds Disability Questionnaire), Roland and Morris disability questionnaire. All these outcome measure showed statistically significant decreases. Oral treatment with alpha-lipoic acid (ALA) and gamma-linolenic acid (GLA) for six weeks in synergy with rehabilitation therapy improved neuropathic symptoms and deficits in patients with radicular neuropathy.

RESUMO

Rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis are commonly thought of as inflammatory diseases that affect younger individuals. Although the initial presentation of these diseases is common in a patients twenties or thirties, they usually persist for the duration of the patients life. In addition, up to one-third of patients with RA have disease onset after 60 years of age. Anti-TNF-a therapies now have well-recognized safety profiles that have been demonstrated in the usual clinical trial populations for these diseases, but such populations under-represent patients > or =65 years of age. This retrospective study aims to determine the safety profiles for etanercept, infliximab and adalimumab in patients of 65 years or more, undergoing anti-TNF treatment for an active inflammatory disease such as rheumatoid arthritis, ankylosing spondylitis or psoriatic arthritis, or skin disease like psoriasis. Our data show that admitting elderly patients into anti-TNF therapeutic regimens is a safe option and that it grants these patients access to the best current therapeutic option, possibly leading to better disease outcome. Quality of life in elderly patients affected by arthritis or psoriasis, often reduced by comorbidities, is as important as quality of life in younger patients. Applying the recommended screening before using biological treatment helps to reduce adverse events related to the therapy, and the application of the same screening in elderly patients seems to lead to comparable results.

RESUMO

To determine the microbial ecology of pasteurized milk within the United States, 2% fat pasteurized fluid milk samples were obtained from 18 dairy plants from 5 geographical areas representing the Northeast, Southeast, South, Midwest, and West. Of the 589 bacterial isolates identified using DNA sequence-based subtyping methods, 346 belonged to genera characterized as gram-positive endospore-forming bacteria (i.e., Bacillus and Paenibacillus). Of the 346 gram-positive endospore-forming bacteria isolated in the present study, 240 were classified into 45 allelic types identical to those previously identified from samples obtained in New York State, indicating the widespread presence of these microbes in fluid milk production and processing systems in the United States. More than 84% of the gram-positive spore-forming isolates characterized at d 1, 7, and 10 were of the genus Bacillus, whereas more than 92% of isolates characterized at d 17 of shelf life were of the genus Paenibacillus, indicating that the predominant gram-positive spoilage genera shifts from Bacillus spp. to Paenibacillus spp. during refrigerated storage.
