RESUMO

BACKGROUND AND PURPOSE: Dysphagia occurs in up to 50% of all patients with acute stroke. There is debate regarding which is the most effective screening tool in identifying aspiration in patients with acute stroke. We assessed the accuracy of the Sapienza Global Bedside Evaluation of Swallowing after Stroke (GLOBE-3S), which combines the Toronto Bedside Swallowing Screening Test (TOR-BSST©) with oxygen desaturation and laryngeal elevation measurement during swallowing. METHODS: We prospectively enrolled consecutive patients with stroke within 72 h of symptom onset. All patients with stroke firstly underwent a standard neurological examination, then the GLOBE-3S evaluation and finally the fiberoptic endoscopic evaluation of swallowing (FEES). Two different assessors, a neurologist and a speech pathologist, blind to both the clinical data and each other's evaluation, administered the GLOBE-3S and FEES examination. We assessed the accuracy of the GLOBE-3S in detecting post-stroke swallow impairment with aspiration using the FEES as the standard. RESULTS: We enrolled 50 patients with acute stroke, 28 of whom (56%) had swallowing impairment with aspiration at FEES evaluation. A total of 33 patients (66%) failed the GLOBE-3S evaluation. The GLOBE-3S reached a sensitivity of 100% and a specificity of 77.3% (negative predictive value, 100%; positive likelihood ratio, 4.34). The median time required for the GLOBE-3S to be performed was 297 s. CONCLUSIONS: GLOBE-3S is quick to perform at the bedside and can accurately identify aspiration in patients with acute stroke. By including the measurement of laryngeal elevation and monitoring of oxygen desaturation, it could represent a highly sensitive instrument to avoid the misdiagnosis of silent aspirators.

RESUMO

The advent of three-dimensional imaging and computer-aided surgical simulation (CASS) have brought about a paradigm shift in surgical planning. The aim of this study was to assess the accuracy of maxillary repositioning surgery using computer-aided design and manufacturing (CAD/CAM) customized titanium surgical guides and fixation plates. Thirty consecutive adult patients, 13 male and 17 female, with a mean age of 29.2 years and 25.5 years, respectively, requiring Le Fort I maxillary osteotomy, with or without simultaneous mandibular surgery, were evaluated retrospectively. All orthognathic surgeries were performed by one experienced surgeon. The pre-surgical and post-surgical volumetric imaging were superimposed to assess the linear and angular differences between the planned and actual positions of the maxilla following surgery. With the use of the CAD/CAM titanium surgical guides and fixation plates, all surgical movements were within 2mm and 4° of the planned movements, which is considered clinically insignificant. The overall root mean square error between the planned and actual surgical movements was 0.38mm in the transverse dimension, 0.64mm in the anteroposterior dimension, and 0.55mm in the vertical dimension. In regard to the centroid of the maxilla, the absolute angular difference of the maxillary centroid was 1.06° in pitch, 0.47° in roll, and 0.49° in yaw. Maxillary repositioning surgery can be performed with high accuracy using CAD/CAM titanium surgical guides and fixation plates.

RESUMO

BACKGROUND & AIMS: Gastric dysfunction in the elderly may cause reduced food intake, frailty, and increased mortality. The pacemaker and neuromodulator cells interstitial cells of Cajal (ICC) decline with age in humans, and their loss contributes to gastric dysfunction in progeric klotho mice hypomorphic for the anti-aging Klotho protein. The mechanisms of ICC depletion remain unclear. Klotho attenuates Wnt (wingless-type MMTV integration site) signaling. Here, we examined whether unopposed Wnt signaling could underlie aging-associated ICC loss by up-regulating transformation related protein TRP53 in ICC stem cells (ICC-SC). METHODS: Mice aged 1-107 weeks, klotho mice, APCΔ468 mice with overactive Wnt signaling, mouse ICC-SC, and human gastric smooth muscles were studied by RNA sequencing, reverse transcription-polymerase chain reaction, immunoblots, immunofluorescence, histochemistry, flow cytometry, and methyltetrazolium, ethynyl/bromodeoxyuridine incorporation, and ex-vivo gastric compliance assays. Cells were manipulated pharmacologically and by gene overexpression and RNA interference. RESULTS: The klotho and aged mice showed similar ICC loss and impaired gastric compliance. ICC-SC decline preceded ICC depletion. Canonical Wnt signaling and TRP53 increased in gastric muscles of klotho and aged mice and middle-aged humans. Overstimulated canonical Wnt signaling increased DNA damage response and TRP53 and reduced ICC-SC self-renewal and gastric ICC. TRP53 induction persistently inhibited G1/S and G2/M cell cycle phase transitions without activating apoptosis, autophagy, cellular quiescence, or canonical markers/mediators of senescence. G1/S block reflected increased cyclin-dependent kinase inhibitor 1B and reduced cyclin D1 from reduced extracellular signal-regulated kinase activity. CONCLUSIONS: Increased Wnt signaling causes age-related ICC loss by up-regulating TRP53, which induces persistent ICC-SC cell cycle arrest without up-regulating canonical senescence markers.

RESUMO

OBJECTIVES: Sexual violence can have a destructive impact on the lives of people. It is more common in unstable conditions such as during displacement or migration of people. On the Greek island of Lesvos, Médecins Sans Frontières provided medical care to survivors of sexual violence among the population of asylum seekers. This study describes the patterns of sexual violence reported by migrants and asylum seekers and the clinical care provided to them. METHODS: This is a descriptive study, using routine program data. The study population consisted of migrants and asylum seekers treated for conditions related to sexual violence at the Médecins Sans Frontières clinic on Lesvos Island (September 2017-January 2018). RESULTS: There were 215 survivors of sexual violence who presented for care, of whom 60 (28%) were male. The majority of incidents reported (94%) were cases of rape; 174 (81%) of survivors were from Africa and 185 (86%) of the incidents occurred over a month before presentation. Half the incidents (118) occurred in transit, mainly in Turkey, and 76 (35%) in the country of origin; 10 cases (5%) occurred on Lesvos. The perpetrator was known to the survivor in 23% of the cases. The need for mental health care exceeded the capacity of available mental care services. CONCLUSION: Even though the majority of cases delayed seeking medical care after the incident, it is crucial that access to mental health services is guaranteed for those in need. Such access and security measures for people in transit need to be put in place along migration routes, including in countries nominally considered safe, and secure routes need to be developed.

RESUMO

Large-scale, unbiased proteomics studies are constrained by the complexity of the plasma proteome. Here we report a highly parallel protein quantitation platform integrating nanoparticle (NP) protein coronas with liquid chromatography-mass spectrometry for efficient proteomic profiling. A protein corona is a protein layer adsorbed onto NPs upon contact with biofluids. Varying the physicochemical properties of engineered NPs translates to distinct protein corona patterns enabling differential and reproducible interrogation of biological samples, including deep sampling of the plasma proteome. Spike experiments confirm a linear signal response. The median coefficient of variation was 22%. We screened 43 NPs and selected a panel of 5, which detect more than 2,000 proteins from 141 plasma samples using a 96-well automated workflow in a pilot non-small cell lung cancer classification study. Our streamlined workflow combines depth of coverage and throughput with precise quantification based on unique interactions between proteins and NPs engineered for deep and scalable quantitative proteomic studies.

RESUMO

Frameworks for limiting ecosystem exposure to excess nutrients and acidity require accurate and complete deposition budgets of reactive nitrogen (Nr). While much progress has been made in developing total Nr deposition budgets for the U.S., current budgets remain limited by key data and knowledge gaps. Analysis of National Atmospheric Deposition Program Total Deposition (NADP/TDep) data illustrates several aspects of current Nr deposition that motivate additional research. Averaged across the continental U.S., dry deposition contributes slightly more (55%) to total deposition than wet deposition and is the dominant process (>90%) over broad areas of the Southwest and other arid regions of the West. Lack of dry deposition measurements imposes a reliance on models, resulting in a much higher degree of uncertainty relative to wet deposition which is routinely measured. As nitrogen oxide (NOx) emissions continue to decline, reduced forms of inorganic nitrogen (NHx = NH3 + NH4+) now contribute >50% of total Nr deposition over large areas of the U.S. Expanded monitoring and additional process-level research are needed to better understand NHx deposition, its contribution to total Nr deposition budgets, and the processes by which reduced N deposits to ecosystems. Urban and suburban areas are hotspots where routine monitoring of oxidized and reduced Nr deposition is needed. Finally, deposition budgets have incomplete information about the speciation of atmospheric nitrogen; monitoring networks do not capture important forms of Nr such as organic nitrogen. Building on these themes, we detail the state of the science of Nr deposition budgets in the U.S. and highlight research priorities to improve deposition budgets in terms of monitoring and flux measurements, leaf- to regional-scale modeling, source apportionment, and characterization of deposition trends and patterns.

RESUMO

Over the last decades, there has been a significant increase in incidence and prevalence of heart failure, a major cause of cardiac morbidity and mortality. Measurements of neurohormones, in particular B-type natriuretic peptide (BNP), can significantly improve diagnostic accuracy, and also correlate with long-term morbidity and mortality in patients with chronic heart failure presenting to the emergency department. BNP is secreted by cardiac ventricles mainly in response to wall stress and neurohormonal factors like the sympathetic nervous system, endothelins, and the rennin-angiotensin-aldosterone system. BNP increases myocardial relaxation and oppose the vasoconstrictive, sodium retaining, and natriuretic effects caused by vasoconstrictive factors. BNP is the first biomarker to prove its clinical value for the diagnosis of left ventricular systolic and diastolic dysfunction but also for the right ventricular dysfunction, guiding prognosis and therapy management. Emerging clinical data will help further refine biomarker-guided therapeutic and monitoring strategies involving BNP.

RESUMO

Late arterial hypertension has been identified as a major predictor for morbidity and mortality in aortic coarctation (AoC) patients. Few data are available about efficacy and tolerability of angiotensin converting enzyme inhibitors vs beta-blockers in young AoC patients. This study aimed to evaluate the tolerability and efficacy on 24-h blood pressure (BP) and left ventricular mass/height(2.7) (LVMI), of atenolol vs enalapril. We enrolled consecutive AoC hypertensive patients with (a) no history of BP treatment or after >48 h of withdrawn, (b) aged 6-20 years, (c) body mass index (BMI) <90th percentile for age and sex, (d) >12 months from a successful AoC repair and (e) no major associated cardiovascular abnormalities. All patient were evaluated with 24-h ambulatory BP monitoring, standard echocardiography, strain-strain rate imaging, at enrolment, 3, 6 and 12 months of treatment. We studied 51 AoC patients (13±3.9 years, BMI: 21.4±4.3 kg m(-2)). Patients were randomly assigned at atenolol treatment (n=26), or enalapril treatment (n=25). The mean follow-up duration was 11±2 months. Both drugs were able to significantly reduce 24-systolic BP (SBP; atenolol: 133±11 mm Hg vs 124±16 mm Hg, P=0.016; enalapril: 135±6 mm Hg vs 127±7 mm Hg, P=0.001). Only enalapril was able to significantly reduce LVMI (47±12 vs 39.6±10 g m(-)(2.7), P=0.016). Only in atenolol group in two cases (7.7%) drug withdrawal was needed because of adverse events. Enalapril and atenolol are similarly effective in reducing SBP. However, only enalapril demonstrated a significant reduction of LVMI. In no case, enalapril was stopped because of adverse events.

RESUMO

Recombinant interleukin-2 (rIL-2) can produce impairment of renal function with hypotension, fluid retention, elevated blood urea nitrogen, oliguria and low fractional sodium excretion; these side-effects are a common cause of reduction or interruption of rIL-2 infusion. The aim of this study was to investigate the control and treatment of renal toxicity induced by rIL-2 therapy. Here we show that dopamine, at a low dose of 2 micrograms/kg/min, completely prevented renal toxicity induced by rIL-2. While continuing rIL-2 therapy, 24-h continuous infusion of low-dose dopamine produced a rapid normalisation of urine output and a significant decrease in serum creatinine levels and body weight (P < 0.01), with an early and complete recovery of the rIL-2--impaired renal function: mean recovery time of renal function in patients treated with dopamine was significantly lower (P < 0.05) than in nontreated patients (4.8 days vs. 10 days, respectively).

RESUMO

Hepatocellular carcinoma (HCC) on liver cirrhosis (LC) is a neoplasm with a poor prognosis. Only 10-36% of patients have resectable tumors at presentation, systemic chemotherapy is seldom useful and loco-regional treatments are feasible only in selected cases. On the basis of the possible role of depression of immune function in the pathogenesis of HCC on LC, we employed thymostimulin in the treatment of patients with unresectable HCC on LC, with the aim of influencing the course of the disease. Forty-six consecutive patients with HCC were enrolled from January 1987 to December 1993. All patients, 36 males and 10 females, with a median age of 67 years (range 58-82) had coexisting LC. All patients were treated with thymostimulin (TP-1 Serono) at doses of 70 mg/day i.m. five times a week until disease progression. Eleven patients achieved an objective response, with an overall response rate of 24%. Six patients obtained a CR (13.0%) with a median duration of 19+ months (range 5+/-23). Five patients (11%) achieved PR with a median duration of 10 months (range 7+/-22). Six patients (13.0%) presented MR (median duration: 12.5 months) and 12 (26.0%) had SD (median duration: 8 months). In 17 patients (36.9%) the disease progressed. Thymostimulin treatment was well tolerated and no major side effect was observed. Thymostimulin treatment can be considered a new promising therapy for advanced HCC.

RESUMO

Aim of the study was to improve cure rate and survival of aggressive non-Hodgkin's lymphoma (NHL) with a tailored program of therapy based on histologic type, prognostic characteristics of patients and response to therapy, and with the use of differentiating or cytostatic agents such as Ara-C at low doses and alphaIFN. Fifty-four consecutive patients with aggressive NHL were treated in the induction phase with 4 sequential courses of a third generation regimen (modified CODBLAM IV), followed in responsive patients by 1 cycle of doxorubicin and cyclophosphamide and 1 cycle of high dose methotrexate with folinic acid rescue (AC-MTX). Patients who achieved partial response (PR) were treated with the combination of CCNU + vinblastine if affected by high grade NHL, or with low dose Ara-C plus alphaIFN if affected by intermediate grade NHL. Patients who obtained complete response (CR) with basal adverse prognostic factors were treated with alphaIFN as maintenance therapy for two years. Radiotherapy and surgery were effected in selected cases. Thirty-four patients (62.9%) achieved CR and 12 patients (22.2%) showed PR after induction therapy. Among the 12 patients who achieved PR, 6 prolonged CRs were obtained in 7 patients treated with Ara-C at low doses plus alphaIFN and 4 CRs were obtained in 5 patients treated with CCNU + vinblastine. After completion of treatment, 44 patients (81.5%) obtained CR, 2 patients (3.7%) showed PR and 8 patients (14.8%) presented progression of disease (PD). Fifteen patients received alphaIFN as maintenance therapy. The overall survival and failure-free survival rates are 53.7% and 50% respectively, with a median follow-up of 82 months: 27 patients remain alive, disease-free without relapses, and can be considered cured. This tailored program of therapy resulted effective and moderately toxic and may improve the outcome in aggressive NHL.

RESUMO

On the basis of a possible pathogenetic role of immunodepression in the development of hepatocellular carcinoma in patients with chronic hepatitis B/C viral infection and liver cirrhosis, we treated 34 liver cirrhosis patients (M/F 24/10; age: 14 pts less than or equal to 60 years, 20>60; Performance status: 22 0-1, 12 2-3; Childs' grade: 21 A, 13 B; ascites yes/not: 4/30) employing thymostimulin (TST), at the dosage of 50 mg/m(2) i.m. 3 times a week, until death or severe toxicity occurrence. Etiology of cirrhosis was viral in all cases. The patients were followed up every 3 months by means of clinical examination and biochemical analyses; every 6 months by checking viral serum markers, alpha-fetoprotein and by means of ultrasounds. To date, 34 patients have been treated, with a median follow-up of 6 (1-8) years. No occurrence of hepatocellular carcinoma has been observed, with a statistically significant difference between observed and expected HCC (p<0.05). Thymostimulin treatment was well tolerated. Our data seem to suggest that the immunomodulating treatment could significantly reduce the risk of HCC occurrence in patients with liver cirrhosis.

RESUMO

Intercellular adhesion molecule-1 (ICAM-1), is a cell surface molecule involved in many immunological processes. Recently, ICAM-1 has also been detected as a soluble form in sera of patients affected by different pathologies and often associated with severity of the disease. However, all these studies were carried out in patients before drug treatment. Since in vitro experiments and recent evidence in humans has indicated the possibility that some cytokines may be responsible of ICAM-1 release, we have considered the possibility of quantitating ICAM-1 in sera of patients undergoing therapy with drugs influencing cytokine regulation. Thymostimulin, which seems to belong to this category, has been used in a pilot study by some of us in the treatment of patients with liver cirrhosis associated with hepatocellular carcinoma. By using an enzymatic sandwich assay, we found significantly high circulating ICAM-1 mean values in patients affected by liver cirrhosis alone or associated with hepatocellular carcinoma or non-Hodgkin lymphoma compared to control subjects (p<0.001), Moreover, in patients with hepatocellular carcinoma or liver cirrhosis who were treated with thymostimulin, serial detection of c-ICAM-1 was carried out and patients responsive to the drug showed significantly increased values of c-ICAM-1 (p=0.006), Our study suggests that an evaluation of c-ICAM-1 levels needs to be considered in the context of the therapeutic approach, with particular attention to those drugs which may affect the regulation of the cytokine pathway.

RESUMO

Monoclonal antibody SP-2, which binds to a 90,000 daltons tumor-associated antigen termed 90K, was generated by mouse immunization with proteins released by human breast cancer cells into the culture medium (Iacobelli et al: Cancer Res 46: 3005-3010, 1986). Elevated 90K levels have been previously reported in the serum of patients with various malignancies. We investigated whether the circulating levels of 90K antigen might be related to prognosis of patients with Non-Hodgkin's Lymphomas (NHL). Serum samples were obtained from 50 apparently healthy blood donors and 81 patients with NHL. Circulating serum 90K concentrations (U/ml) were determined by a solid-phase immunoradiometric assay (IRMA) by a two-step procedure. Serum 90K levels were significantly higher in patients with NHL than in healthy controls (p=0.004). The Kaplan-Meier analysis of overall survival showed that patients with 90K-negative (serum 90K levels less than or equal to 16 U/ml) survived longer than patients with 90K-positive sera (less than or equal to 16 U/ml) (p=0.004). Multivariate regression analysis revealed that serum levels of LDH and 90K were the two independent prognostic variables for predicting overall survival. We propose that an elevated 90K antigen level in sera is a predictor of poor prognosis in NHL.

RESUMO

Fifteen patients from a series of 37 consecutive patients with aggressive NHL who achieved a complete remission (CR) with first line chemotherapy were defined at high or high-intermediate risk of relapse according to International Prognostic Risk Index and were treated with alpha IFN as maintenance therapy for two years. After a median follow-up of 62 months only 3/15 patients (20%) relapsed and 2/15 (13.3%) died in the alpha IFN treated group, favourably comparing with the expected relapse and death rate in that setting; on the other hand 40.9% of 'low risk' patients from the same series, who did not receive alpha IFN, had relapsed. alpha IFN maintenance therapy appears to result in prolonged response duration and survival in patients with aggressive and prognostically unfavourable NHL.

RESUMO

The antitumor activity and toxicity profile of a new therapeutic combination was investigated for patients with non-Hodgkin's lymphoma (NHL). The regimen consisted of mitoxantrone (10 mg/m(2)/day by intravenous (i.v.) bolus injection on day 1), etoposide (100 mg by 24 hours continuous i.v. infusion on days 1, 2, 3) and bleomycin (4 mg by i.v. bolus injection on day 1 followed by 24 hours continuous i.v. infusion at 4 mg/m2/day dose on days 1, 2, 3) (MEB). MEB chemotherapy was administered to 22 patients affected by intermediate/high grade or clinically symptomatic low grade NHL who were considered non-elegible for standard cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) chemotherapy. Major responses were achieved in 11/22 (50%) patients with 5 (23%) complete responses. Grade 3-4 neutropenia occurred in 59% of patients. The results of this study demonstrate that MEB chemotherapy possesses good antitumor activity and a manageable toxicity in a prognostically unfavourable subset of lymphoma patients.

RESUMO

High dose Verapamil (VP) infusion has been incorporated into cytotoxic chemotherapy in order to circumvent tumor cell drug-resistance. We have evaluated the cardiovascular side-effects produced by high dose VP associated to EPOCH chemotherapy in 12 patients with chemorefractory lymphoma. Continuous monitoring of right ventricular and pulmonary pressure and cardiac index was performed in three patients by a Swan-Ganz catheter. A slight reduction in cardiac index was observed 6 h after the beginning of VP infusion and was followed by spontaneous recovery within 12 h. First degree atrioventricular (AV) block was detected in 6/12 patients. Premature Ventricular Beats (PVB) occurred in one patient, and promptly disappeared after xylocaine administration. All patients experienced mild and transient hypotension, while severe hypotension was observed only in 1 patient, who promptly recovered when VP administration was discontinued. Hypokalemia was detected in 6 patients possibly as a consequence of transient activation of the renin-angiotensin system.

RESUMO

BACKGROUND: Travel health risks documented by questionnaire surveys obtained (e.g., during homebound flights) are incomplete since they miss most patients who need to be repatriated. METHODS: All patient claim files were reviewed from 1997 to 1998, of the largest Swiss travel insurance company. RESULTS: Among 242 claims, 69.4% were due to illness, 30.6% due to accidents; infections were the most frequent illnesses, the extremities were the most frequently traumatized part of the body. Although the illness-to-accident ratio was 1:5 in industrialized countries and the Caribbean, it exceeded 3:0 in some developing regions. Accident proneness was noted in the first week abroad. CONCLUSION: Even if no denominator data are available, this analysis offers an insight in travel health risks, allowing comparison of the occurrences of very different, serious, health problems abroad.
