Abstract
Background and Purpose—
Many patients with acute ischemic stroke are not eligible for thrombolysis or mechanical reperfusion therapies due to contraindications, inaccessible vascular occlusions, late presentation, or large infarct core. Sphenopalatine ganglion (SPG) stimulation to enhance collateral flow and stabilize the blood-brain barrier offers an alternative, potentially more widely deliverable, therapy.
Methods—
In a randomized, sham-controlled, double-masked trial at 41 centers in 7 countries, patients with anterior circulation ischemic stroke not treated with reperfusion therapies within 24 hours of onset were randomly allocated to active SPG stimulation or sham control. The primary efficacy outcome was improvement beyond expectations on the modified Rankin Scale of global disability at 90 days (sliding dichotomy), assessed in the modified intention-to-treat population. The initial planned sample size was 660 patients, but the trial was stopped early when technical improvements in device placement occurred, so that analysis of accumulated experience could be conducted to inform a successor trial.
Results—
Among 303 enrolled patients, 253 received at least one active SPG or sham stimulation, constituting the modified intention-to-treat population (153 SPG stimulation and 100 sham control). Age was median 73 years (interquartile range, 64–79), 52.6% were female, deficit severity on the National Institutes of Health Stroke Scale was median 11 (interquartile range, 9–15), and time from last known well median 18.6 hours (interquartile range, 14.5–22.5). For the primary outcome, improved 3-month disability beyond expectations, rates in the SPG versus sham treatment groups were 49.7% versus 40.0%; odds ratio, 1.48 (95% CI, 0.89–2.47);
P
=0.13. A significant treatment interaction with stroke location (cortical versus noncortical) was noted,
P
=0.04. In the 87 patients with confirmed cortical involvement, rates of improvement beyond expectations were 50.0% versus 27.0%; odds ratio, 2.70 (95% CI, 1.08–6.73);
P
=0.03. Similar response patterns were observed for all prespecified secondary efficacy outcomes. No differences in mortality or serious adverse event safety end points were observed.
Conclusions—
SPG stimulation within 24 hours of onset is safe in acute ischemic stroke. SPG stimulation was not shown to statistically significantly improve 3-month disability above expectations, though favorable outcomes were nominally higher with SPG stimulation. Beneficial effects may distinctively be conferred in patients with confirmed cortical involvement. The results of this study need to be confirmed in a larger pivotal study.

Usage characteristics and adverse event rates of the direct puncture and pull techniques for percutaneous endoscopic gastrostomy in patients with malignant tumors of the upper aerodigestive tract. Endosc Int Open 2018; 6:E29-E35. [PMID: 29340295 PMCID: PMC5766340 DOI: 10.1055/s-0043-121879] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2017] [Accepted: 09/12/2017] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND AND STUDY AIMS Patients with malignant tumors of the upper gastrointestinal tract are at risk of weight loss. Early supportive nutrition therapy is therefore recommended and usually requires placement of a percutaneous endoscopic gastrostomy (PEG). The aim of this study was to compare adverse events and usage characteristics of the direct puncture technique with those of the traditional pull technique when used in patients with endoscopically passable tumors. The primary endpoint was the rate of inflammatory adverse events (AEs) at the gastrostomy fistula. The secondary endpoint was the long-term rate of puncture-site metastases. PATIENTS AND METHODS One hundred twenty patients (median age 56; IQR 36, 86 years) were randomized and treated per protocol in this prospective open randomized single-center study. Follow-ups were conducted on the third and seventh post-interventional days, after 1, 3 and 6 months and the last follow-up 5 years after intervention. RESULTS Within the short-term follow-up period of 6 months after PEG placement, AEs were noted in 47 patients (39.2 %). These included 22 inflammations and 16 device dislocations and were mainly found in the puncture group (33 vs. 14 in the pull group) with a significantly increased incidence in the first month after PEG insertion ( P = 0.001). Evaluation of the 5-year data did not reveal any significant differences. The gastrostomy tube was used in 101 patients (84.2 %) (range 18 days to 5 years). CONCLUSIONS Our results favor the pull technique for patients with endoscopically passable tumors of the upper gastrointestinal tract due to less short-term adverse events. Both systems contributed equally to secure long-term use.

Factors associated with non-participation and dropout among cancer patients in a cluster-randomised controlled trial. Eur J Cancer Care (Engl) 2017; 27. [PMID: 28134477 DOI: 10.1111/ecc.12645] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/05/2016] [Indexed: 12/01/2022]
Abstract
We investigated the impact of demographic and disease related factors on non-participation and dropout in a cluster-randomised behavioural trial in cancer patients with measurements taken between hospitalisation and 6 months thereafter. The percentages of non-participation and dropout were documented at each time point. Factors considered to be potentially related with non-participation and dropout were as follows: age, sex, marital status, education, income, employment status, tumour site and stage of disease. Of 1,338 eligible patients, 24% declined participation at baseline. Non-participation was higher in older patients (Odds Ratio [OR] 2.1, CI: 0.6-0.9) and those with advanced disease (OR 2.0, CI: 0.1-1.3). Dropout by 6 months was 25%. Dropout was more frequent with increased age (OR 2.8, CI: 0.8-1.2), advanced disease (OR 3.0, CI: 1.0-1.2), being married (OR 2.4, CI 0.7-1.1) and less frequent with university education (OR 0.4, CI -1.3 to -0.8) and middle income (OR 0.4, CI -0.9 to -0.7). When planning clinical trials, it is important to be aware of patient groups at high risk of non-participation or dropout, for example older patients or those with advanced disease. Trial designs should consider their special needs to increase their rate of participation.

Impact of socio-economic position on cancer stage at presentation: Findings from a large hospital-based study in Germany. Int J Cancer 2016; 139:1696-702. [PMID: 27244597 DOI: 10.1002/ijc.30212] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2015] [Revised: 03/23/2016] [Accepted: 04/19/2016] [Indexed: 12/20/2022]
Abstract
We explored the relationship between socio-economic characteristics and cancer stage at presentation. Patients admitted to a university hospital for diagnosis and treatment of cancer provided data on their education, vocational training, income, employment, job, health insurance and postcode. Tumor stage was classified according to the Union International Contre le Cancer (UICC). To analyze disparities in the likelihood of late-stage (UICC III/IV vs. I/II) diagnoses, logistic regression models adjusting for age and gender were used. Out of 1,012 patients, 572 (59%) had late-stage cancer. Separately tested, increased odds of advanced disease were associated with post-compulsory education compared to college degrees, with apprenticeship and no vocational training, with unemployment, disability pension, jobs with a low hierarchy level, blue collar jobs and with low income. Health insurance and community size were not related with late-stage cancer. Jointly modelled, there was evidence for an independent effect of unemployment (odds ratio (OR) 1.7, CI 1.0-2.8), disability pension (OR 1.8, CI 1.0-3.2) and very low income (OR 2.6, CI 1.1-6.1) on the likelihood of advanced disease stage. It is of great concern that these socio-economic gradients occur even in systems with equal access to health care.

Abstract
OBJECTIVES Co-occurrence of oral lichen planus (OLP) and chronic hepatitis C virus (HCV) infection suggests a strong association, but the relation between mucocutaneus, autoimmune lichen planus and HCV infection remains unclear. In areas with higher prevalence of HCV infection in general population, like Japan and southern Europe, 20 to 40 % of patients with OLP test positive for anti-HCV antibodies, whereas in German populations, a co-occurrence of 4.2 to 16 % was reported. MATERIAL AND METHODS We screened 143 patients with histopathologically proven OLP for prevalence of anti-HCV antibodies. Additionally, we examined 51 anti-HCV-positive subjects with current or past HCV infection for clinical symptoms of OLP. In all patients, confirmatory diagnosis was made by the detection of HCV RNA via reverse transcription-polymerase chain reaction (RT-PCR). A randomized control group comprised 109 blood sera samples of patients without any characteristics of OLP. RESULTS The results of all patients showed no co-occurrence in either cohort. CONCLUSION In conclusion, no association between oral lichen planus and chronic HCV infection in our study population was found. CLINICAL RELEVANCE Anti-HCV antibody screening in patients with confirmed oral lichen planus is not indicated routinely in central Germany.

Effect of a structured psycho-oncological screening and treatment model on mental health in cancer patients (STEPPED CARE): study protocol for a cluster randomized controlled trial. Trials 2014; 15:482. [PMID: 25491069 PMCID: PMC4295289 DOI: 10.1186/1745-6215-15-482] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2014] [Accepted: 11/20/2014] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND High levels of emotional distress in cancer patients often goes unnoticed in daily clinical routine, resulting in severe undertreatment of mental health problems in this patient group. Screening tools can be used to increase case identification, however, screening alone does not necessarily translate into better mental health for the patient. Doctors play a key role in providing basic emotional support and transferring the patients in need of such specific support to mental health professionals. This study investigates whether a stepped care model, combining screening, doctor consultation and professional psycho-oncological service in a structured way, improves the emotional wellbeing of cancer patients. METHODS/DESIGN This study is a cluster randomized trial with two parallel groups (intervention vs. care as usual), set in an academic hospital. Participants are cancer patients, a total of 1,000 at baseline. The intervention consists of stepped psychosocial care. Step one: screening for distress, step two: feedback of screening results to the doctor in charge of the patient and consultation with the patient, and step three: based on a shared patient-doctor decision, either transferal to the consultation liaison (CL) service or not. The outcome will be emotional well-being half a year after baseline, ascertained with the Hospital Anxiety and Depression Scale. Randomization will be done by the cluster randomization of wards. DISCUSSION Mental health problems not only cause emotional suffering but also direct and indirect costs. This calls for timely and adequate psychosocial support, especially as we know that such support is effective. However, not every cancer patient can and must be treated by a mental health professional. Allocating limited resources most sensibly and economically is of crucial importance for our healthcare system to ensure the best quality of care to as many patients as possible. It is the hope of the STEPPED CARE trial that this model is both effective and efficient, and that it can be implemented in other hospitals as well, if proven to be effective.

Co-morbid mental health conditions in cancer patients at working age--prevalence, risk profiles, and care uptake. Psychooncology 2013; 22:2291-7. [PMID: 23494948 DOI: 10.1002/pon.3282] [Citation(s) in RCA: 45] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2012] [Revised: 02/16/2013] [Accepted: 02/18/2013] [Indexed: 12/14/2022]
Abstract
OBJECTIVE This study examined the prevalence of mental health conditions in cancer patients, the role of socioeconomic position in relation to that, and the use of professional mental health care. METHODS Prospective cohort with measurements at the beginning of inpatient treatment (baseline) and 3, 9, and 15 months after baseline using structured clinical interviews based on DSM-IV, questionnaires, and medical records. RESULTS At baseline, 149 out of 502 cancer patients (30%) were diagnosed with a mental health condition. Prevalence was associated with unemployment (odds ratio [OR] 2.0), fatigue (OR 1.9), and pain (OR 1.7). Of those with mental health conditions, 9% saw a psychotherapist within 3 months of the diagnosis, 19% after 9 months, and 11% after 15 months. Mental health care use was higher in patients with children ≤18 years (OR 3.3) and somatic co-morbidity (OR 2.6). There was no evidence for an effect of sex on the use of mental health care. CONCLUSION Few cancer patients with psychiatric disorders receive professional mental health care early enough. If patients are unemployed or if they suffer from fatigue or pain, special attention should be paid because the risk of having a mental health condition is increased in these patients.

Transforming growth factor-beta receptor type 1 (TGFBR1) is not associated with non-syndromic cleft lip with or without cleft palate in patients of Central European descent. Int J Pediatr Otorhinolaryngol 2009; 73:1334-8. [PMID: 19586667 DOI: 10.1016/j.ijporl.2009.06.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2009] [Revised: 05/31/2009] [Accepted: 06/08/2009] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Transforming growth factor-beta (TGF-β) type 1 receptor (also known as activin receptor-like kinase 5, ALK5) is expressed in palatal tissue during embryogenesis. Experimental studies in transgenic mice with a genetic deletion of Alk5 showed that TGF-β type 1 receptor is required for upper lip and midline fusion of the hard and soft palate. In humans, association of TGF-β type 1 receptor gene (TGFBR1) and the development of non-syndromic cleft lip with or without cleft palate (NSCL/P) had been observed in a multiethnic sample of Chinese, Philippine, Indian and Turkish families. In order to re-evaluate the relevance of these findings, we carried out a family-based association study among 218 NSCL/P families of Central European descent. METHODS Genomic DNA was obtained from peripheral blood of 218 complete parent-offspring triads with NSCL/P. The sample comprised 14 patients with cleft lip only (CLO) and 204 patients with cleft lip and palate (CLP). Genotyping and transmission disequilibrium test (TDT) were performed on all 218 triads with a total of 17 tagging single-nucleotide polymorphisms (SNPs). We also performed testing for extended haplotypes and a log-linear model by Weinberg was used to screen parent-of-origin effects. Furthermore the use of estimates for the relative risks (RR) of Weinberg's model was obtained. RESULTS TDT analysis revealed no significant transmission distortion, neither at the level of individual markers nor at the level of haplotypes. Similarly negative results were obtained when we restricted our analysis to the subgroup of patients with CLP (n=204). Relative risk calculations (RR) of the children's and mothers' genotypes obtained negative results, after correction of p-values for multiple testing. Likewise application of Weinberg's log-linear model did not find any evidence for parent-of-origin effects in our sample. CONCLUSION Despite the ample evidence supporting the role of TGF-β type 1 receptor as a critically important and widespread morphogenetic regulator of craniofacial development in murine models, our results do not support TGFBR1 as major risk factor for NSCL/P in patients of Central European descent.

Abstract
Objective: The 677C→T allele in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene has been implicated in the etiology of nonsyndromic cleft lip and palate (CL/P). This study involved a family-based association study of the MTHFR polymorphism. Patients/participants: We examined 181 patients with CL/P of central European descent and their parents for this variant. Results: The transmission disequilibrium test (TDT) did not confirm an association between the MTHFR 677C→T polymorphism and nonsyndromic CL/P as previously suggested (p = .36). When comparing the offspring of mothers with periconceptional use of folate to those without, no statistically significant differences were found (p = .708). Conclusion: Our data suggest that the MTHFR 677C→T polymorphism does not make a major contribution to the occurrence of CL/P among central Europeans.

Abstract
BACKGROUND AND OBJECTIVES Despite the availability of initial data on sentinel lymph node biopsy (SLNB) in OSCC, its value in clinical practice remains unclear. The aim of this study is to evaluate the feasibility and potential of SLNB as a reliable staging procedure in early stage SCC of the lips and the oral mucosa. METHODS From 2001 to 2004, 40 patients with early stage SCC of the lips and oral cavity were enrolled. The main inclusion criteria were: cN0 category by MRI and ultrasound, tumor category T1-T2, for certain sites also T3. Patients with positive SLN underwent MRND and/or radiation. Patients with negative SLN were monitored monthly. RESULTS In eight patients, the SLN were positive. Two patients with negative SLN subsequently developed nodal disease (5% false negatives). Twenty-one patients have a follow-up longer than 24 months. Five patients died (one from nodal disease, one from local recurrence, and three from unrelated causes). One patient developed a second primary tumor, the remaining patients are free of disease. CONCLUSIONS SLNB may contribute to more targeted lymph node dissection strategies. Further studies will have to ensure the safety of this procedure in comparison to selective neck dissection.

Abstract
Worldwide an estimated 1.5-2 billion people are infested with helminths. Over the last decades, in industrialized countries prevalence rates of human helminthic infections were decreased by means of wastewater and food control. In this article, we review the geographic distributions as well as the impact on the public health system of the most prevalent helminthiases. Special emphasis is given to Echinococcus, Enterobiasis, and Toxocariasis. Intestinal larvae or eggs of helminths can be detected in faeces. Pinworms are collected with a strip of cellophane tape with the sticky side towards the anus. Tissue helminthosis, like Toxocariasis or Trichinosis are associated with eosinophilia and can be diagnosed with sensitive immunological methods or by biopsy. Infection with Echinococcus multilocularis is the most serious parasitic disease in central Europe. Although current therapeutic options are limited, 5 year survival rates were markedly improved by the combination of medical and surgical treatment.

Abstract
Human helminthic infestations are extraordinarily common in tropical regions and represent a significant burden for those countries and their populations. The risk of intestinal helminthoses is further increased by poverty. Particularly in children helminthoses lead to malnutrition (ascariasis etc) or iron and protein deficiency (ancylostomiasis). Tropical helminthoses like schistosomiasis and filariasis can cause severe organ damage, starvation, and early death. In contrast, returning travellers very rarely acquire tropical helminthoses, if they follow simple hygienic rules. Furthermore, the worm burden in returning travelers hardly ever is high enough to cause severe illness. Therefore, tropical helminthosis is more common in immigrants from endemic areas compared to returning travelers.
