Developmental Measures: The Zika Virus, Microcephaly, and Histories of Global Northern State Anxieties

This project seeks to understand anxious and fearful responses to the Zika virus and microcephaly that began circulating widely in February, 2016. My project works to uncover racial histories embedded in the contemporary scientific and medical practice of measuring head circumference. By arguing that microcephaly is a racialized metric of civilizational and human development, I show that responses to Zika’s proliferation invoke state security because Global Northern states imagine microcephaly as a developmental, economic, and cultural lag. Dominant scientific and medical characterizations of microcephaly constitute modern, developed states as such by making political conceptions of normalcy and capacity seem natural: microcephaly is marked as “abnormal” in the scientific literature that instructs the measurement, surveillance, and diagnosis developmental and cognitive disabilities. Seemingly disparate contemporary moments and histories–among them the 2016 Rio Olympics, histories of racial purity and contamination, phrenology, and eighteenth-century racialized notions of sexuality—are inextricably linked to ideals and practices of white, bourgeois subjectivity. Like the diagnostic category of microcephaly, these ideals and practices are inherently unstable and insecure: they cannot exist nor materialize without the economic and social exploitation of racialized and disabled populations

Are obesity and rheumatoid arthritis interrelated

OBJECTIVES In recent years, both the prevalence of obesity and the incidence of RA have been rising. Our aim was to assess the association between overweight or obesity and rheumatoid arthritis (RA). DESIGN Patients who were diagnosed with RA were compared with population-based controls, matched for age and sex (by a ratio of 1:5). Body measurements and smoking status were collected from medical records. Body mass index was classified in WHO categories of underweight, normal, overweight and obese (<18.5, 18.5-<25, 25-<30, ≥30 kg/m2 ). χ2 and t-tests and logistic regression models were used to compare the study groups and to assess the association between obesity and RA. SETTING A cross-sectional analysis performed utilizing the database of Clalit Health Services, the largest healthcare provider organisation in Israel. Data were collected from the beginning of computerised database usage (around year 2000) until 2015. PARTICIPANTS CHS covers over 4.4 million enrollees, of which all RA patients and matched controls were selected. MAIN OUTCOME MEASURES Proportion of obesity (BMI≥30.0 kg/m2 ) among RA patients and controls. RESULTS The study included 11 406 patients with RA and 54 701 controls. The proportion of obese subjects among RA patients was higher in comparison with controls, (33.4% vs 31.6%, respectively). In multivariate regression model, smoking and obesity were found to be associated with RA, whereas male gender was found as inversely related to RA. CONCLUSIONS Our findings demonstrate that obesity is significantly associated with RA. This finding underlines the role that obesity plays in inflammation and autoimmune conditions

In situ measurement of humidity induced changes in the refractive index and thickness of polyethylene glycol thin films

6th International Conference on PhotonicsHumidity induced changes in the refractive index and thickness of polyethylene glycol (PEG) thin films are in situ determined by optical waveguide spectroscopy. PEG brushes are covalently attached to the surface of a thin gold film on a borosilicate crown glass (BK7) using a grafting-from chemical synthesis technique. The measurements are carried out in an attenuated total internal reflection setup. At low humidity levels, both the refractive index and the thickness change gradually due to swelling of the PEG thin films upon water intake. At around 80% relative humidity, a steep decrease in the refractive index and a steep increase in the thickness are observed as a result of a phase change from a semicrystalline state to a physical gel state. The hydrogenation of PEG films causes a less pronounced phase change from a semicrystalline state to a gel state. Due to fewer ether oxygen atoms available for the water molecules to make hydrogen bonding, the polymer has a more stable structure than before and the phase change is observed to shift to higher humidity levels. It is discussed that such a humidity induced change in the index of refraction can be utilized in constructing of a PEG based humidity sensor.Czech & Slovak Soc Photonc; Act M Agcy; Czech Tech Univ; Acad Sci Czech Republic; Slovak Acad Sci; Meopta Prerov; SPIE; SPIE Europe; European Opt Soc; Opt Soc Ame

Long-Term Follow-Up of Flexible Bronchoscopic Treatment for Bronchial Carcinoids with Curative Intent

Background. Typical pulmonary carcinoids represent less than 5% of primary lung tumors. In patients with typical bronchial carcinoid, formal surgical resection still remains the gold-standard treatment. Data regarding long-term outcome in using flexible bronchoscope-based modalities under conscious sedation is very limited. Objectives. We sought to investigate, over extended follow-up period, the effectiveness of endobronchial resection for carcinoid tumors with curative intent using flexible bronchoscopy. Methods. Nd:YAG laser photoresection using flexible bronchoscope under conscious sedation. Follow-up included repeat bronchoscopy every 6 months and chest CT every year. Results. Ten patients aged 24 to 70 years with endobronchial carcinoid were treated. The tumor location was variable: 2 left Main bronchus, 1 left upper lobe bronchus, 2 right main bronchus, 2 right middle lobe bronchus and 3 right lower lobe bronchus. No major complications were observed. The patients required between 2 and 4 procedures. Patients were followed for a median period of 29 months with no evidence of tumor recurrence. Conclusions. Endobronchial laser photoresection of typical bronchial carcinoids using flexible bronchsocopy under conscious sedation is an effective treatment modality for a subgroup of patients that provides excellent long-term results that are similar to outcome obtained by more invasive procedures

Enthesitis: Much More Than Focal Insertion Point Inflammation

Purpose of Review Recognition of the importance of enthesitis as the pivotal pathological process underpinning spondyloarthropathies (SpA) has increased in recent years. Thus, we summarized the current knowledge on the pathogenic role of enthesitis on SpA shown by both animal models and human studies in vivo. Recent Findings Experimental models have shown several SpA-like diseases that commence at entheses and are linked to nail disease as well as dactylitis, two important entheseal-associated conditions in humans. Frequently, enthesitis is not the primary outcome measure in studies of peripheral PsA and SpA although arguably it is the key parameter being indirectly assessed in spinal disease in ankylosing spondylitis. The use of different agents including JAK, IL-17, and IL-23 inhibitors contributes significantly to our understanding of enthesitis in terms of involved immune pathways. Summary Enthesitis and enthesis organ inflammation may be the primary pathological process underlying SpA associated skeletal inflammation. Emergent studies are beginning to elucidate the molecular basis for this type of joint inflammatory response

The Impact of Intermittent Fasting (Ramadan Fasting) on Psoriatic Arthritis Disease Activity, Enthesitis, and Dactylitis: A Multicentre Study

Intermittent circadian fasting, namely Ramadan, is a common worldwide practice. Such fasting has a positive impact on psoriasis, but no data exist on its role in psoriatic arthritis (PsA)—a disease that is clearly linked to body mass index. We enrolled 37 patients (23 females and 14 males) with a mean age 43.32 ± 7.81 and they fasted for 17 h for one month in 2016. The baseline PsA characteristics were collected and 12 (32.4%) patients had peripheral arthritis, 13 (35.1%) had axial involvement, 24 (64.9%) had enthesitis, and 13 (35.1%) had dactylitis. Three patients (8.1%) were treated with methotrexate, 28 (75.7%) with TNF-α blockers, and 6 (16.2%) with IL-17 blockers. After a month of intermittent fasting, C-reactive protein (CRP) levels decreased from 14.08 ± 4.65 to 12.16 ± 4.46 (p < 0.0001), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) decreased from 2.83 ± 1.03 to 2.08 ± 0.67 (p = 0.0078), Psoriasis Area Severity Index (PASI) decreased from 7.46 ± 2.43 to 5.86 ± 2.37 (p < 0.0001), and Disease Activity index for PSoriatic Arthritis (DAPSA) decreased from 28.11 ± 4.51 to 25.76 ± 4.48 (p < 0.0001). Similarly, enthesitis improved after fasting, with Leeds Enthesitis Index (LEI) decreasing from 2.25 ± 1.11 to 1.71 ± 0.86 (p < 0.0001) and dactylitis severity score (DSS) decreasing from 9.92 ± 2.93 to 8.54 ± 2.79 (p = 0.0001). Fasting was found to be a predictor of a decrease in PsA disease activity scores (DAPSA, BASDAI, LEI, DSS) even after adjustment for weight loss. IL-17 therapy was found to be an independent predictor of decreases in LEI after fasting. These preliminary data may support the use of chronomedicine in the context of rheumatic diseases, namely PsA. Further studies are needed to support our findings

Causes of Sudden Death Related to Sexual Activity : Results of a Medicolegal Postmortem Study from 2001 to 2005

Sexual activity (SA), combined with organic heart disease, may cause sudden death (SD). However, the causes of SD related to SA are not known well. The aim of this study was to assess the causes of SD related to SA. From August 2001 to November 2005, all autopsies (n=1,379) performed at Kyungpook National University were prospectively searched for SD cases related to SA. Fourteen cases (46±11 yr old, 9 males) of SD related to SA were found. All were heterosexual. The toxicologic study was negative in all. Ten cases were witnessed; during SA in 4 cases, just after SA in another 4 cases, 2 and 5 hr after in 1 each case. In 4 unwitnessed cases the victims were found dead less than 12 hr from the end of their SA. The partners were steady extramarital partners (n=8), prostitutes (n=2), marital partner (n=1) and unknown (n=3). The causes of the SD were as follows; coronary artery disease in 6, subarachnoid hemorrhage with ruptured berry aneurysm in 4, fibromuscular dysplasia of the atrioventricular nodal artery in 2, and unknown in 2. Coronary artery disease and subarachnoid hemorrhage with ruptured berry aneurysm were important as causes of SD related to SA
