RESUMEN

BACKGROUND: Indirect effects of the COVID-19 pandemic on communities in fragile and conflict-affected settings may be severe due to reduced access and use of healthcare, as happened during the 2015 Ebola Virus Disease outbreak. Achieving a balance between short-term emergency response and addressing long-term health needs is particularly challenging in fragile and conflict-affected settings such as South Sudan, given the already significant barriers to accessing healthcare for the population. This study sought to characterise the effect of COVID-19 on healthcare access and South Sudan's healthcare response. This can inform efforts to mitigate the potential impacts of COVID-19 or other epidemiological threats, and contribute to understanding how these may be balanced for greater health system resilience in fragile contexts. METHODS: We conducted a mixed methods study in three of South Sudan's states, combining data from a cross-sectional quantitative household survey with qualitative interviews and Focus Group Discussions. RESULTS: Even though some fears related to COVID-19 were reported, we found these did not greatly dissuade people from seeking care and do not yield significant consequences for health system programming in South Sudan. The pillars of the response focused on risk communication and community engagement were effective in reaching communities through different channels. Respondents and participants reported behaviour changes that were in line with public health advice. We also found that the implementation of COVID-19 response activities sometimes created frictions between the national government and international health actors, and that COVID-19 caused a greater reliance on, and increased responsibility for, international donors for health planning. CONCLUSIONS: Given the fact that global priorities on COVID-19 are greatly shifting, power dynamics between international health agencies and the national government may be useful to consider in further COVID-19 planning, particularly for the vaccine roll-out. South Sudan must now navigate a period of transition where COVID-19 vaccine roll-out continues and other domestic health burdens are re-prioritised.

RESUMEN

The human response to the COVID-19 pandemic set in motion an unprecedented shift in human activity with unknown long-term effects. The impacts in marine systems are expected to be highly dynamic at local and global scales. However, in comparison to terrestrial ecosystems, we are not well-prepared to document these changes in marine and coastal environments. The problems are two-fold: 1) manual and siloed data collection and processing, and 2) reliance on marine professionals for observation and analysis. These problems are relevant beyond the pandemic and are a barrier to understanding rapidly evolving blue economies, the impacts of climate change, and the many other changes our modern-day oceans are undergoing. The "Our Ocean in COVID-19″ project, which aims to track human-ocean interactions throughout the pandemic, uses the new eOceans platform (eOceans.app) to overcome these barriers. Working at local scales, a global network of ocean scientists and citizen scientists are collaborating to monitor the ocean in near real-time. The purpose of this paper is to bring this project to the attention of the marine conservation community, researchers, and the public wanting to track changes in their area. As our team continues to grow, this project will provide important baselines and temporal patterns for ocean conservation, policy, and innovation as society transitions towards a new normal. It may also provide a proof-of-concept for real-time, collaborative ocean monitoring that breaks down silos between academia, government, and at-sea stakeholders to create a stronger and more democratic blue economy with communities more resilient to ocean and global change.

RESUMEN

PURPOSE: This study aims to know what proportion of culture day 5 pre-blastocyst-stage embryos develop into blastocysts by culture day 6 and what patient and cycle characteristics are associated with delayed blastocyst formation. METHODS: A retrospective observational cohort analysis was performed including a total of 9886 embryos from 1008 IVF cycles in 835 patients, who underwent treatment between January 1, 2016, and December 31, 2018. Autologous fresh in vitro fertilization (IVF) cycles at a single academic center were included in the analysis. Embryos were group-cultured using single-step culture media. Blastulation was defined as the presence of a new blastocyst. Usable blastulation was defined as the presence of a new good or excellent quality, expanded, hatching, or hatched blastocysts. RESULTS: The mean blastulation rate between days 5 and 6 of extended embryo culture was 30.9%. The mean percentage of embryos developing into usable blastocyst-stage embryos was 19.8%. The factors associated with blastulation on day 6 included the total number of embryos and the number of pre-blastocysts on day 5, as well as the use of ICSI. Age, the number of total embryos, those remained in culture and pre-blastocysts, as well as the blastulation rate on day 5 were associated with usable blastulation. CONCLUSION: It is important to know the usable blastocyst development rate between culture days 5 and 6 in order to adequately counsel patients debating whether to proceed with fresh ET on day 5 or forego ET with the expectation that embryos will be biopsied for PGT and/or cryopreserved on culture day 6. Our findings provide evidence to help guide patients in this difficult decision.

RESUMEN

BACKGROUND: This study investigated the efficacy and tolerability of wearing frozen gloves (FGs) during chemotherapy to prevent chemotherapy-induced peripheral neuropathy (CIPN) as reported by patients and influence on quality of life (QoL). PATIENTS AND METHODS: Cancer patients starting treatment with oxaliplatin, docetaxel or paclitaxel between February 2013 and May 2016 at the medical oncology department were eligible. Patients were randomized into groups wearing FGs on both hands during treatment and those not wearing FGs during treatment. Self-reported CIPN and QoL were measured with the European Organisation for the Research and Treatment of Cancer Quality of Life (EORTC QLQ) CIPN20 and QLQ-C30 at four time points: baseline (t0), after three cycles (t1), end of chemotherapy (t2) and after 6 months (t3). RESULTS: The study included 180 patients with 90 patients in both arms. They mostly underwent treatment of colorectal or breast cancer. Thirty-one patients (34%) discontinued FGs, mainly due to discomfort. Intention-to-treat analyses showed no important differences in reported EORTC QLQ CIPN20 subscales between the FG group and control group; however, the analyses showed the patients experienced reduced tingling in fingers/hands [ß = -10.20, 95% confidence interval (CI) = -3.94 to -3.14, P = 0.005] and less trouble opening a jar or bottle due to loss of strength in hands (ß = -6.97, 95% CI = -13.53 to -0.40, P = 0.04) in the FG group compared with the control group. Per-protocol analyses showed similar results: reduced aching or burning pain in fingers/hands (ß = -4.37, 95% CI = -7.90 to -0.83, P = 0.02) and cramps in hands (ß = -3.76, 95% CI = -7.38 to -0.14, P = 0.04). Differences in tingling in fingers/hands at t1 were clinically relevant. In addition, those treated with FGs reported overall better QoL (ß = 4.79, 95% CI = 0.37 to 9.22, P = 0.03) and physical functioning (ß = 5.66, 95% CI = 1.59 to 9.73, P = 0.007) than the control. No difference in dose reductions was observed. CONCLUSIONS: No difference in CIPN subscales was reported between intervention arms. Wearing FGs might reduce some neuropathy symptoms in the hands, potentially resulting in a better QoL; however, one-third of the FG group discontinued the study before the end of treatment. Future studies should focus on the method of limb hypothermia to prevent CIPN. TRIAL REGISTRATION NUMBER: NL39650.015.12.

RESUMEN

OBJECTIVE: Exercise is one of the most potent strategies available to support cognitive health with age, yet substantial variability exists. Sexual dimorphism is evident for brain and immune functioning, the latter being implicated as important pathway for exercise. We examined the moderating role of sex on the relationship between physical activity and systemic inflammatory and brain health outcomes in support of more personalized approaches to behavioral interventions. METHODS: Our discovery cohort included 45 typically aging women matched on age (±5y) and education (±2y) to 45 men (mean age = 72.5; Clinical Dementia Rating = 0) who completed self-reported current physical activity (Physical Activity Scale for Elderly), blood draw, neuropsychological evaluation, and brain MRI. An independent sample of 45 typically aging women and 36 men who completed the same measures comprised a replication cohort. Plasma was analyzed for 11 proinflammatory cytokine and chemokine markers via MesoScale Discovery. RESULTS: Discovery cohort: Reported physical activity did not differ between sexes (150 vs. 157, p = 0.72). There was a significant interaction between sex and physical activity on chemokine markers MDC, MIP-1b, MCP-4, and eotaxin-3 (ps < 0.03), with a similar trend for MCP-1 and INFγ (ps < 0.09). Men who reported greater activity demonstrated lower inflammatory markers, an effect attenuated-to-absent in women. An interaction between sex and physical activity was also observed for parahippocampal volumes (p = 0.02) and cognition (processing speed and visual memory; ps < 0.04). Again, the beneficial effect of physical activity on outcomes was present in men, but not women. Replication cohort analyses conferred a consistent effect of sex on the relationship between physical activity and immune markers; models examining neurobehavioral outcomes did not strongly replicate. Across cohorts, post-hoc models demonstrated an interaction between sex and activity-related inflammatory markers on total gray matter volume and visual memory. Men with higher inflammatory markers demonstrated poorer brain structure and function, whereas inflammatory markers did not strongly relate to neurobehavioral outcomes in women. CONCLUSIONS: Greater physical activity was associated with lower markers of inflammation in clinically normal older men, but not women - an effect consistently replicated across cohorts. Additionally, men appeared disproportionately vulnerable to the adverse effects of peripheral inflammatory markers on brain structure and function compared to women. Immune activation may be a male-specific pathway through which exercise confers neurobehavioral benefit.

RESUMEN

AIM: For many European countries, including Germany, no valid estimates are available on age at diagnosis of Type 2 diabetes. Thus, we aimed to estimate the age at diagnosis in Germany. METHODS: Age at diagnosis of Type 2 diabetes in Germany was estimated based on Type 2 diabetes prevalence and incidence and the age distribution of the German population. Age- and sex-specific incidence and prevalence in 2014/2015, based on claims data from statutory health insurance (n= 69 000 000, ~85% of the German population), and the age pyramid for Germany in 2015 were used for the calculation. Age at Type 2 diabetes diagnosis was stratified by sex. CIs were estimated using bootstrap methods. In addition, the age range in which 50% of the population received a diagnosis of Type 2 diabetes was calculated (the interquartile range). RESULTS: The mean ± sd age at Type 2 diabetes diagnosis in 2015 was 61.0 ± 13.4 years (95% CI 60.9-61.0) in men. Women were diagnosed ~2 years later than men (mean age 63.4 ± 14.9 years; 95% CI 63.4-63.5). The age range in which 50% of the population was diagnosed with diabetes was 53-72 years for men and 54-76 years for women. CONCLUSIONS: The sex differences are mainly attributable to a higher incidence of Type 2 diabetes in men than women during middle age and the higher absolute number of women in the older ages. The early age at diabetes diagnosis compared to average life expectancy means that the risk of diabetes-related complications is increased.

RESUMEN

BACKGROUND: There is increasing evidence that long-term complications in organic acidemias are caused by impaired mitochondrial metabolism. Currently, there is no specific biomarker to monitor mitochondrial dysfunction in organic acidemias. Serum fibroblast growth factor 21 (FGF-21) is a biomarker for mitochondrial disease and could be a candidate to monitor mitochondrial function in the deleterious course of disease. METHODS: Data of 17 patients with classical organic acidemias (11 propionic acidemia (PA), four methylmalonic acidemia (MMA) and two isovaleric acidemia (IVA) patients) were included. The clinical course was evaluated; metabolic decompensations and long-term complications were correlated with plasma FGF-21 levels. Cardiomyopathy, prolonged QT interval, renal failure, and optic neuropathy were defined as long-term complications. RESULTS: Patients ages ranged from 16 months up to 32 years. Serious long-term complications occurred in eight patients (five PA and three MMA patients). In MMA and PA patients plasma FGF-21 levels during stable metabolic periods were significantly higher in patients with long-term complications (Mdn = 2556.0 pg/ml) compared to patients without (Mdn = 287.0 pg/ml). A median plasma FGF-21 level above 1500 pg/ml during a stable metabolic period, measured before the occurrence of long-term complications, had a positive predictive value of 0.83 and a negative predictive value of 1.00 on long-term complications in MMA and PA patients. CONCLUSION: This study demonstrates the potential role of FGF-21 as a biomarker for long-term complications in classical organic acidemias, attributed to mitochondrial dysfunction.

RESUMEN

Prevalence of invasive ß-haemolytic streptococci (BHS) at a tertiary care hospital and molecular diversity of S. pyogenes and S. dysgalactiae was studied. Between 2012 and 2016, all blood culture sets (n = 55,839), CSF (n = 8413) and soft tissue (n = 20,926) samples were analysed for BHS positivity using HYBASE software. Molecular profiles of 99 S. pyogenes and S. dysgalactiae were identified by sequencing of M protein genes (emm types) and multiplex PCR typing of 20 other virulence determinants. Streptococci contributed to 6.2% of blood, 10.7% of CSF and 14.5% of soft tissue isolates, being among the most common invasive isolates. The overall rates of invasive S. pyogenes, S. agalactiae, S. dysgalactiae and S. pneumoniae were 2.4, 4.4, 2.1, and 5.3%. Whereas S. pneumoniae was 1.5% more common in CSF samples, BHS isolates were 2-fold and 11-fold higher in bacteraemia and invasive soft tissue infections. Genetic BHS typing revealed wide molecular diversity of invasive and noninvasive group A and group G BHS, whereas one emm-type (stG62647.0) and no other virulence determinants except scpA were detected in invasive group C BHS. BHS were important invasive pathogens, outpacing S. pneumoniae in bacteraemia and invasive soft tissue infections. The incidence of S. dysgalactiae infections was comparable to that of S. pyogenes even with less diversity of molecular virulence. The results of this study emphasise the need for awareness of BHS invasiveness in humans and the need to develop BHS prevention strategies.

RESUMEN

AIM: To describe for the first time the direct costs of Type 2 diabetes treatment by analysing nationwide routine data from statutory health insurance in Germany. METHODS: This cost-of-illness-study was based on a 6.8% random sample of all German people with statutory health insurance (4.3 out of 70 million people). The healthcare expenses show direct per capita costs from the payer perspective. Healthcare expenses for physicians, dentists, pharmacies, hospitals, sick benefits and other healthcare costs were considered. Per capita costs, cost ratios for people with Type 2 diabetes and without diabetes as well as diabetes-attributable costs were calculated. RESULTS: Per capita costs for people with Type 2 diabetes amounted to €4,957 in 2009 and €5,146 in 2010. People with Type 2 diabetes had 1.7-fold higher health expenses than people without diabetes. The largest differences in health expenses were found for prescribed medication from pharmacies (cost ratio diabetes/no diabetes: 2.2) and inpatient treatment (1.8). Ten percent of the total statutory health insurance expense, in total €16.1 billion, was attributable to the medical care of people with Type 2 diabetes. CONCLUSIONS: This nationwide study indicates that one in 10 Euros of healthcare expenses is spent on people with Type 2 diabetes in Germany. In the future, national statutory health insurance data can be used to quantify time trends of costs in the healthcare system.

RESUMEN

No studies have evaluated the association between the dietary inflammatory index (DII) and colorectal adenoma recurrence. DII scores were calculated from a baseline food frequency questionnaire. Participants (n = 1727) were 40-80 years of age, enrolled in two Phase III clinical trials, who had ≥1 colorectal adenoma(s) removed within 6 months of study registration, and a follow-up colonoscopy during the trial. Multiple logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). No statistically significant associations were found between DII and odds of colorectal adenoma recurrence [ORs (95% CIs) = 0.93 (0.73, 1.18) and 0.95 (0.73, 1.22)] for subjects in the second and third DII tertiles, respectively, compared to those in the lowest tertile (Ptrend = 0.72). No associations were found for recurrent colorectal adenoma characteristics, including advanced recurrent adenomas, large size, villous histology, or anatomic location. While our study did not support an association between a proinflammatory diet and colorectal adenoma recurrence, future studies are warranted to elucidate the role of a proinflammatory diet on the early stages of colorectal carcinogenesis.

RESUMEN

Since the first description of Wohlfahrtiimonas chitiniclastica in 2008, a number of well described case reports demonstrating its pathogenic role in humans have been published. Infections may be closely linked to flies, such as Wohlfahrtia magnifica, Lucilia sericata, Chrysomya megacephala or Musca domestica. These insects are potent vectors for the distribution of W. chitiniclastica causing local or systemic infections originating from wounds infested with fly larvae. However, other potential sources of transmission of W. chitiniclastica have been described such as soil or chicken meat. Infections in humans reported to date comprise wound infections, cellulitis, osteomyelitis and sepsis. This review summarizes all the literature available up to now and gives the current knowledge about this emerging human pathogen. Additionally, four patients with proven W. chitiniclastica infections treated at Dresden University Hospital between 2013 and 2015, are included. Special focus was placed on microbiological identification and antibiotic susceptibility testing of the pathogen.

RESUMEN

BACKGROUND: Accumulating evidence supports an effect of aspirin in reducing overall cancer incidence and mortality in the general population. We reviewed current data and assessed the benefits and harms of prophylactic use of aspirin in the general population. METHODS: The effect of aspirin for site-specific cancer incidence and mortality, cardiovascular events was collated from the most recent systematic reviews. Studies identified through systematic Medline search provided data regarding harmful effects of aspirin and baseline rates of harms like gastrointestinal bleeding and peptic ulcer. RESULTS: The effects of aspirin on cancer are not apparent until at least 3 years after the start of use, and some benefits are sustained for several years after cessation in long-term users. No differences between low and standard doses of aspirin are observed, but there were no direct comparisons. Higher doses do not appear to confer additional benefit but increase toxicities. Excess bleeding is the most important harm associated with aspirin use, and its risk and fatality rate increases with age. For average-risk individuals aged 50-65 years taking aspirin for 10 years, there would be a relative reduction of between 7% (women) and 9% (men) in the number of cancer, myocardial infarction or stroke events over a 15-year period and an overall 4% relative reduction in all deaths over a 20-year period. CONCLUSIONS: Prophylactic aspirin use for a minimum of 5 years at doses between 75 and 325 mg/day appears to have favourable benefit-harm profile; longer use is likely to have greater benefits. Further research is needed to determine the optimum dose and duration of use, to identify individuals at increased risk of bleeding, and to test effectiveness of Helicobacter pylori screening-eradication before starting aspirin prophylaxis.

RESUMEN

BACKGROUND: Body mass index (BMI), a measure of obesity typically assessed in middle age or later, is known to be positively associated with pancreatic cancer. However, little evidence exists regarding the influence of central adiposity, a high BMI during early adulthood, and weight gain after early adulthood on pancreatic cancer risk. DESIGN: We conducted a pooled analysis of individual-level data from 20 prospective cohort studies in the National Cancer Institute BMI and Mortality Cohort Consortium to examine the association of pancreatic cancer mortality with measures of central adiposity (e.g. waist circumference; n = 647 478; 1947 pancreatic cancer deaths), BMI during early adulthood (ages 18-21 years) and BMI change between early adulthood and cohort enrollment, mostly in middle age or later (n = 1 096 492; 3223 pancreatic cancer deaths). Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards regression models. RESULTS: Higher waist-to-hip ratio (HR = 1.09, 95% CI 1.02-1.17 per 0.1 increment) and waist circumference (HR = 1.07, 95% CI 1.00-1.14 per 10 cm) were associated with increased risk of pancreatic cancer mortality, even when adjusted for BMI at baseline. BMI during early adulthood was associated with increased pancreatic cancer mortality (HR = 1.18, 95% CI 1.11-1.25 per 5 kg/m(2)), with increased risk observed in both overweight and obese individuals (compared with BMI of 21.0 to <23 kg/m(2), HR = 1.36, 95% CI 1.20-1.55 for BMI 25.0 < 27.5 kg/m(2), HR = 1.48, 95% CI 1.20-1.84 for BMI 27.5 to <30 kg/m(2), HR = 1.43, 95% CI 1.11-1.85 for BMI ≥30 kg/m(2)). BMI gain after early adulthood, adjusted for early adult BMI, was less strongly associated with pancreatic cancer mortality (HR = 1.05, 95% CI 1.01-1.10 per 5 kg/m(2)). CONCLUSIONS: Our results support an association between pancreatic cancer mortality and central obesity, independent of BMI, and also suggest that being overweight or obese during early adulthood may be important in influencing pancreatic cancer mortality risk later in life.

RESUMEN

BACKGROUND: Irreversible electroporation (IRE) is a new technique for tumour cell ablation that is reported to involve non-thermal-based energy using high voltage at short microsecond pulse lengths. In vivo assessment of the thermal energy generated during IRE has not been performed. Thermal injury can be predicted using a critical temperature model. The aim of this study was to assess the potential for thermal injury during IRE in an in vivo porcine model. METHODS: In vivo continuous temperature assessments of 86 different IRE procedures were performed on porcine liver, pancreas, kidney and retroperitoneal tissue. Tissue temperature was measured continuously throughout IRE by means of two thermocouples placed at set distances (0·5 cm or less, and 1 cm) from the IRE probes within the treatment field. Thermal injury was defined as a tissue temperature of 54°C lasting at least 10 s. Tissue type, pulse length, probe exposure length, number of probes and retreatment were evaluated for associations with thermal injury. In addition, IRE ablation was performed with metal clips or metal stents within the ablation field to determine their effect on thermal injury. RESULTS: An increase in tissue temperature above the animals' baseline temperature (median 36·0°C) was generated during IRE in all tissues studied, with the greatest increase found at the thermocouple placed within 0·5 cm in all instances. On univariable and multivariable analysis, ablation in kidney tissue (maximum temperature 62·8°C), ablation with a pulse length setting of 100 µs (maximum 54·7°C), probe exposure of at least 3·0 cm (maximum 52·0°C) and ablation with metal within the ablation field (maximum 65·3°C) were all associated with a significant risk of thermal injury. CONCLUSION: IRE can generate thermal energy, and even thermal injury, based on tissue type, probe exposure lengths, pulse lengths and proximity to metal. Awareness of probe placement regarding proximity to critical structures as well as probe exposure length and pulse length are necessary to ensure safety and prevent thermal injury. A probe exposure of 2·5 cm or less for liver IRE, and 1·5 cm or less for pancreas, with maximum pulse length of 90 µs will result in safe and non-thermal energy delivery with spacing of 1·5-2·3 cm between probe pairs.

RESUMEN

Gamow-Teller (GT) transitions in atomic nuclei are sensitive to both nuclear shell structure and effective residual interactions. The nuclear GT excitations were studied for the mass number A = 42, 46, 50, and 54 "f-shell" nuclei in ((3)He, t) charge-exchange reactions. In the (42)Ca → (42)Sc reaction, most of the GT strength is concentrated in the lowest excited state at 0.6 MeV, suggesting the existence of a low-energy GT phonon excitation. As A increases, a high-energy GT phonon excitation develops in the 6-11 MeV region. In the (54)Fe → (54)Co reaction, the high-energy GT phonon excitation mainly carries the GT strength. The existence of these two GT phonon excitations are attributed to the 2 fermionic degrees of freedom in nuclei.

RESUMEN

OBJECTIVE: International research shows that oncology staff suffers more from burnout than other healthcare professionals. Burnout is common among oncologists. The prevalence of emotional exhaustion, depersonalization, and low personal accomplishment appears to be significantly higher among physicians. Detecting burnout is highly relevant, because it affects the personal well-being and quality of life of the healthcare professional. A national study on the prevalence of burnout in oncology was never conducted in Flanders (Dutch-speaking part of Belgium). METHODS: The Cédric Hèle institute spread anonymous questionnaires among 923 healthcare workers in oncology (physicians, social workers, psychologists, nurses, and specialist-nurses) in Flanders. The questionnaire consisted of two parts. The first part contained questions concerning demographic and job features. The second part included the Dutch version of the Maslach Burnout Inventory. RESULTS: Five hundred and fifty subjects participated in the survey (response rate of 59.5%). Of the medical oncologists, 51.2% suffered from emotional exhaustion, 31.8% from depersonalization, and 6.8% from a lack of personal accomplishment. Multivariate analysis of variance suggested a significantly elevated level of emotional exhaustion and depersonalization in oncologists compared with other professionals. Logistic regression indicated that the following variables have predictive value on risk of burnout: gender, profession, and combining work in a university hospital with work in a private hospital. CONCLUSION: The CHi research showed a significantly increased level of burnout-components in professionals working in oncology, especially in medical oncologists. These results should have an impact on the daily clinic of oncology, and could be guidance for further research.

RESUMEN

BACKGROUND: Studies have shown that somatostatin reduces the occurrence of postoperative pancreatic fistula. However, no study to date has analyzed the cost effectiveness of this treatment. The purpose of this study was to analyze the cost effectiveness of prophylactic somatostatin use with respect to pancreatectomy. METHODS: Review of prospectively collected 2002 patient hepato-pancreatico-biliary database from January 2007 to May 2012. Patients received somatostatin prophylactically at the discretion of their surgeon. Data were analyzed using univariate analysis to determine if somatostatin had an effect on imaging costs, lab costs, "other" costs, PT/OT costs, surgery costs, room and board costs, and total hospital costs. RESULTS: A total of 179 patients underwent pancreatectomy at a single teaching institution. Median total hospital costs were 90,673.50 (59,979-743,667) for patients who developed a postoperative pancreatic fistula versus 86,563 (39,190-463,601) for those who did not (p = 0.004). Median total hospital costs were 89,369 (39,190-743,667) for patients who were administered somatostatin versus 85,291 (40,092-463,601) for patients who did not (p = 0.821). CONCLUSIONS: Pancreatic fistulas significantly increase hospital costs, and somatostatin has been shown to decrease the rate of pancreatic fistula formation. Somatostatin has no significant effect on hospital costs.

RESUMEN

INTRODUCTION: Less invasive spine surgery (LISS) has become well-established for thoracolumbar burst fractures without neurological deficits. However, notable controversy persists regarding the adequacy of LISS for more unstable AO type B and C injuries, as it does not allow for formal open fusion. MATERIALS AND METHODS: In this cross-sectional survey experienced spine surgeons of the Dutch Spine Society were invited to participate (56 participants). They were asked to indicate the most appropriate treatment for AO type B1, B2 (L1: A1 and L1: A3), B3 and C (L1: A4) injuries at level Th12-L1. Taking into account: age, AO N0-N1, or polytrauma. Specific agreement between participants was obtained applying Variation Ratio (VR). RESULTS: A significant level of overall agreement was observed for AO type-B1 injuries with 73.8% of participants opting for percutaneous short-segment fixation (VR 0.775). For AO type-B3 injuries, 79.4% of participants favored percutaneous long-segment fixation (VR 0.794). for AO type-B2 injuries, there was less overall agreement (VR 0.571-0.657). Nonetheless, when considering all AO type-B injuries combined, percutaneous fixation emerged as the most preferred treatment option with substantial agreement (VR 0.871-0.923). Conversely, for AO type-C injuries, there was less agreement among the participants (VI 0.411), 26.5% of them chose additional open spinal fusion. CONCLUSION: For all AO type-B injuries there was substantial agreement to treat these fractures with percutaneous techniques. For AO type-C injuries, the survey results do not support a consensus. Nevertheless, the responses raise important questions about the necessity of spinal fusion for such injuries.

RESUMEN

A randomized phase-II study was performed in low/int-1 risk MDS (IPSS) to study efficacy and safety of lenalidomide without (arm A) or with (arm B) ESA/G-CSF. In arm B, patients without erythroid response (HI-E) after 4 cycles received ESA; G-CSF was added if no HI-E was obtained by cycle 9. HI-E served as primary endpoint. Flow cytometry and next-generation sequencing were performed to identify predictors of response. The final evaluation comprised 184 patients; 84% non-del(5q), 16% isolated del(5q); median follow-up: 70.7 months. In arm A and B, 39 and 41% of patients achieved HI-E; median time-to-HI-E: 3.2 months for both arms, median duration of-HI-E: 9.8 months. HI-E was significantly lower in non-del(5q) vs. del(5q): 32% vs. 80%. The same accounted for transfusion independency-at-week 24 (16% vs. 67%), but similar in both arms. Apart from presence of del(5q), high percentages of bone marrow lymphocytes and progenitor B-cells, a low number of mutations, absence of ring sideroblasts, and SF3B1 mutations predicted HI-E. In conclusion, lenalidomide induced HI-E in patients with non-del(5q) and del(5q) MDS without additional effect of ESA/G-CSF. The identified predictors of response may guide application of lenalidomide in lower-risk MDS in the era of precision medicine. (EudraCT 2008-002195-10).

RESUMEN

Legionnaires' disease is diagnosed predominantly by urinary antigen detection, and patient isolates are rarely available. The lipopolysaccharide (LPS) epitope pattern of isolates detected by monoclonal antibodies is an accepted marker for the phenotyping of L. pneumophila serogroup 1 strains into monoclonal subgroups. L. pneumophila LPS is the dominant antigen in patients' urinary specimens. By using commercially available microtiter wells coated with rabbit anti-Legionella serogroup 1 IgG as the catching antibody, LPS components in urine specimens were bound and detected separately by corresponding monoclonal antibodies of the Dresden Panel. The subtyping of LPS on urinary antigen molecules by using enzyme-linked immunosorbent assay (ELISA) allows deducing of first evidences for the identity/non-identity of environmental isolates and the legionellosis pathogen. Most importantly in our study, urinary antigen typing possesses high probability to distinguish (or does not distinguish) if the pathogen belongs to the MAb 3/1-negative L. pneumophila strains, which are widespread contaminants of water systems, but represent the minority of patient isolates.
