The aim of this study was to evaluate the short-term impact of a group crisis intervention for children aged 9-15 years from five refugee camps in the Gaza Strip during ongoing war conflict. Children were selected if they reported moderate to severe posttraumatic stress reactions, and were allocated to group intervention (N=47) encouraging expression of experiences and emotions through storytelling, drawing, free play and role-play; education about symptoms (N=22); or no intervention (N=42). Children completed the CPTSD-RI and the CDI pre- and post-intervention. No significant impact of the group intervention was established on children's posttraumatic or depressive symptoms. Possible explanations of the findings are discussed, including the continuing exposure to trauma and the non-active nature of the intervention. PMID:15981138

This paper presents a novel optical angiography system, and introduces its medical applications. We developed the optical enhanced imaging system which can observe the blood and lymphatic vessels as the Indocyanine green (ICG) fluorescence image. The imaging system consists of 760nm light emitted diode (LED) as excite light, CCD camera as a detector, a high-pass optical filter in front of the CCD and video processing system. The advantage of ICG fluorescence method is safe (radiation free), high sensitive, real time monitoring of blood and/or lymphatic flow, small size, easy to operate and cost effective compared to conventional X-ray angiography or scintigraphy. We have applied this method to several clinical applications such as breast cancer sentinel lymph node (SLN) navigation, lymph edema diagnostic and identification of liver segmentation. In each application, ICG fluorescence method shows useful result. It's indicated that this method is promising technique as optical angiography.

The near-infrared (NIR) laser radiation due to its high penetration depth is widely used in phototherapy. In application to skin appendages a high selectivity of laser treatment is needed to prevent light action on surrounding tissues. Indocyanine Green (ICG) dye may provide a high selectivity of treatment due to effective ICG uploading by a target and its narrow band of considerable absorption just at the wavelength of the NIR diode laser. The goal of this study is to demonstrate the efficacy of the NIR diode laser phototherapy in combination with topical application of ICG suggested for soft and thermal treatment of acne vulgaris. 28 volunteers with facile or back-located acne were enrolled. Skin sites of subjects were stained by ICG and irradiated by NIR laser-diode light (803 or 809 nm). Untreated, only stained and only light irradiated skin areas served as controls. For soft acne treatment, the low-intensity (803 nm, 10 - 50 mW/cm2, 5-10 min) or the medium-intensity (809 nm, 150 - 190 mW/cm2, 15 min) protocols were used. The single and multiple (up to 8-9) treatments were provided. The individual acne lesions were photothermally treated at 18 W/cm2 (803 nm, 0.5 sec) without skin surface cooling or at 200 W/cm2 (809 nm, 0.5 sec) with cooling. The results of the observations during 1-2 months after the completion of the treatment have shown that only in the case of the multiple-wise treatment a combined action of ICG and NIR irradiation reduces inflammation and improves skin state during a month without any side effects. At high power densities (up to 200 W/cm2) ICG stained acne inflammatory elements were destructed for light exposures of 0.5 sec. Based on the concept that hair follicle, especially sebaceous gland, can be intensively and selectively stained by ICG due to dye diffusion through pilosebaceous canal and its fast uptake by living microorganisms, by vital keratinocytes of epithelium of the canal and sebaceous duct, and by rapidly proliferating

Targeted delivery of therapeutic and imaging agents using surface modified nanovectors has been explored immensely in recent years. The growing demand for site-specific and efficient delivery of nanovectors entails stable surface conjugation of targeting moieties. We have developed a polymeric nanocapsule doped with Indocyanine green (ICG) with potential for targeted and deep tissue optical imaging and phototherapy. Our ICG-loaded nanocapsules (ICG-NCs) have potential for covalent coupling of various targeting moieties and materials due to presence of amine groups on the surface. Here, we covalently bioconjugate polyethylene glycol(PEG)-coated ICG-NCs with monoclonal antibody against HER2 through reductive amination-mediated procedures. The irreversible and stable bonds are formed between anti- EGFR and aldehyde termini of PEG chains on the surface of ICG-NCs. We confirm the uptake of conjugated ICG-NCs by ovarian cancer cells over-expressing HER2 using fluorescent confocal microscopy. The proposed process for covalent attachment of anti-HER2 to PEGylated ICG-NCs can be used as a methodology for bioconjugation of various antibodies to such nano-constrcuts, and provides the capability to use these optically active nano-probes for targeted optical imaging of ovarian and other cancer types.

Indocyanine green (ICG) is an FDA-approved infrared chromophore used for various biomedical applications such as cardiac and hepatic function evaluation, and ophthalmic angiography. Despite its clinical applications, freely dissolved ICG binds non-specifically to various plasma proteins resulting in changes in its near infrared (NIR) emission properties and rapid elimination from the vasculature. To overcome these shortcomings, we have encapsulated ICG within polymeric nano-constructs composed of poly allylamine hydrochloride (PAH) cross-linked with di-sodium hydrogen phosphate (Na2HPO4). To optimize the photophysical properties of nano-encapsulated ICG (NE-ICG) for clinical imaging applications, we report measurements of fluorescent quantum yield (φ) of NE-ICG. Specifically, we constructed capsules of three different diameters (~130, ~240, and ~450 nm). Our preliminary results indicate that NE-ICG shows less quantum yield compared to freely-dissolved ICG. We determined that the 240 nm diameter capsule to have the highest φ and 450 nm diameter capsules to have the least φ at room temperature.

The variety of nanoparticles developed by numerous investigators has presented a diverse platform for various optical imaging applications in biomedicine. We have previously reported that the FDA-approved chromophore Indocyanine Green (ICG) can be successfully encapsulated by cross-linked poly-allylamine hydrochloride (PAH)-Disodium Monophosphate (Na2HPO4) to form a nanoparticle for near-infrared imaging applications. The diameter of the constructs is dependent on the charge ratio between the polymer and salt used to encapsulate the chromophore. Modifications of the synthesis methods can alter the photophysical properties of the capsules, either through the adjustment of the charge ratio between PAH and Na2HPO4 or concentration of ICG successfully impregnated into the capsule. Through understanding the effects of tuning the nanoparticle properties, the photophysical characteristics of the constructs can be optimized. Here we present the results of adjusting the diameter of the nanoparticle and amount of ICG on the hydrodynamic diameters, absorption and fluorescence characteristics, and the relative fluorescence quantum yield. Optimizing the photophysical properties of the constructs can lead to increased imaging sensitivity and contrast for potential translational applications, including tumor imaging, which may utilize these nanoconstructs.

Optical nano-materials present a promising platform for targeted molecular imaging of cancer biomarkers and its photodestruction. Our group is investigating the use of polymeric nanoparticles, loaded with indocyanine green, an FDA-approved chromophore, as a theranostic agent for targeted intraoperative optical imaging and laser-mediated destruction of ovarian cancer. These ICG-loaded nanocapsules (ICG-NCs) can be functionalized by covalent attachment of targeting moieties onto their surface. Here, we investigate ICG-NCs functionalized with anti-HER2 for targeted fluorescence imaging and laser-mediated destruction of ovarian cancer cells in vitro. ICG-NCs are formed through ionic cross-linking between polyallylamine hydrochloride chains and sodium phosphate ions followed by diffusion-mediated loading with ICG. Before functionalization with antibodies, the surface of ICG-NCs is coated with single and double aldehyde terminated polyethylene glycol (PEG). The monoclonal anti-HER2 is covalently coupled to the PEGylated ICG-NCs using reductive amination to target the HER2 receptor, a biomarker whose over-expression is associated with increased risk of cancer progression. We quantify uptake of anti-HER2 conjugated ICG-NCs by ovarian cancer cells using flow cytometery. The in-vitro laser-mediated destruction of SKOV3 cells incubated with anti-HER2 functionalized ICG-NCs is performed using an 808 nm diode laser. Cell viability is characterized using the Calcein and Ethidium homodimer-1 assays following laser irradiation. Our results indicate that anti-HER2 functionalized ICG-NCs can be used as theranostic agents for optical molecular imaging and photodestruction of ovarian cancers in-vitro.

Photodynamic hyperthermal therapy (PHT) with indocyanine green (ICG) is a combination of photodynamic therapy (PDT) and hyperthermia (HT). The low toxicity of ICG with an absorption wavelength of 700-800 nm is thought to make it a good candidate as a photosensitizer for PHT. Upon irradiation, ICG produces oxygen radicals and generates heat. The optimal concentration of ICG and the PHT post-irradiation time effects were evaluated by the cytotoxicity of the treatment on B16F10 murine melanoma. The cytotoxicity of PHT was determined based on the morphology of apoptotic and necrotic cells under phase-contrast microscope, confocal laser scanning microscope (CLSM) with DAPI and Annexin V-FITC/PI double staining, and cell surface structure evaluation by scanning electron microscopy (SEM). The use of ICG at a concentration of 150 µM was selected, as cell proliferation was inhibited from 0 to 24 hr post-PHT with a 3-fold decrease in cell viability (P<0.001) compared to the control group. A morphological observation revealed apoptotic and some degree of necrotic features in the PHT-treated cells. PMID:22134111

A qualitative method using focus group discussions (FGDs) was applied in this study to identify people's perceptions on newspaper reporting pertaining to the Southern Separatist Movement (SSM) by different Yemeni newspapers. This paper also looked into the attitudes towards the movement and the popularity of the issue of Yemeni unification. Five FGD groups with a total of 30 participants discussed the subject and some other aspects related to it. The findings of the focu19 groups showed that the southern crisis and SSM had shaken the people's trust on the current form of the unity. The discussion with the groups revealed that media in general and the selected four papers from various political persuasions have no credibility and objectivity, but these papers are trying to instill democratic values which is consistent with their ideology, which have a serious impact on the value of liberal democracy. The participants assured that reporting on the southern cause and the SSM indicated the absence of professional journalism in the media and the political discourse in general. PMID:26110101

Movies acquired from fundus imaging using Indocyanine Green (ICG) and a scanning laser ophthalmoscope provide information for identifying vascular and other retinal abnormalities. Today, the main limitation of this modality is that it requires esoteric training for interpretation. A straightforward interpretation of these movies by objective measurements would aid in eliminating this training barrier. A software program has been developed and tested that produces and visualizes 2D maps of perfusion measures. The program corrects for frame-to-frame misalignment caused by eye motion, including rigid misalignment and warp. The alignment method uses a cross-correlation operation that automatically detects the distance due to motion between adjacent frames. The d-ICG movie is further corrected by removing flicker and vignetting artifacts. Each pixel in the corrected movie sequence is fit with a least-squares spline to yield a smooth intensity temporal profile. From the dynamics of these intensity curves, several perfusion measures are calculated. The most effective of these measures include a metric that represents the amount of time required for a vessel to fill with dye, a metric that represents the diffusion of dye, and a metric that is affected by local blood volume. These metrics are calculated from movies acquired before and after treatment for a neovascular condition. A comparison of these before and after measures may someday provide information to the clinician that helps them to evaluate disease progression and response to treatment.

renewed economic progress in Russia. Russian scientists could also be an important source of support for democratic norms: sociologists of science have long argued that scientists tend to support democracy because it provides them with the freedom in which their research can flourish. At the same time, a more recent study suggests that funding shortages may override the researcher's need for freedom and drive scientists to align themselves with the economic policies espoused by Nationalists and Communists in order to survive. Therefore, much turns on the question: ''What is the state of science in Russia today?'' The good news is that focus group interviews with Russian nuclear physicists conducted in October 2001 suggest that the ''science in crisis'' image is one-sided and misleading. Though scientists still complained about low salaries, lack of respect in society, and other similar issues, the participants in the focus groups also expressed positive sentiments about recent changes in the field of science. To be sure, the financing of science remains at a considerably lower level than during the heyday of Soviet times. Yet, it is now possible to earn a decent living as a scientist because of the greater availability of foreign and domestic grants and contracts. In addition, state funding has stabilized over the past few years. Thus, it is more accurate to say that Russian science is in a state of transition rather than in a state of crisis.

Fluorescent properties of ICG depends on solvent. Fluorescent characteristics of ICG rubber rings and optimized detection system condition were identified. The fluorescent rubber rings are produced by drying mixture of ICG solution and liquid rubber. LED and laser light sources were used to test differences between them. Other variables are ICG molar concentration (100, 80, 60, 40, 20, 10μM), excitation light spectrum (740, 760, 785nm) and angle of view (0~80°). We observed that ICG ring emitted fluorescence at longer wavelength than in blood and aqueous state. Observation angle between 0 and 50 provided similar brightness of images, while others are significantly less luminous. Excitation light between 740~760nm ensured non-overlapping spectrums of excitation light and fluorescence emission. PMID:27280060

Purpose: To evaluate a method of control of diode laser fluence leading to a reproducible ICG-enhanced selective photocoagulation of blood vessels. This method would use the chromophore clearance, i.e. ICG blood concentration decay to adapt the laser fluence. Materials and Methods: A skin flap window was used on hamsters. After a 15 mg/kg ICG solution injection, photocoagulation of vessels were performed. Results: Selective photocoagulation of blood vessels was obtained only during the first 10 minutes. The fluence required to obtain a selective photocoagulation of vessels (F) was modelized using a one compartment phamacokinetic equation: F equals Of(1-e-t/(tau )). The best fit was obtained for a time constant (tau) equals 4.8 min and Of equals 300 J/cm2 (correlation coefficient r2 equals 0.996). During the first 10 minutes, the fluence required for selective photocoagulation of vessels was increased by a factor 4.5. Conclusion: Fluence required for a selective photocoagulation of vessels was correlated to ICG blood concentration decay. The time constant was equivalent to ICG half-life time in human blood. These results demonstrate that diode laser ICG-enhanced photocoagulation can be controlled by monitoring the ICG blood clearance.

The effects of Ovosiston, Non-Ovlon, Anacyclin, Eugynon, and Deposiston, all oral hormonal contraceptives, on 75 women in fertile age and on the half-life of Ujoviridin (ICG - indocyanine green) were studied prior to treatment as well as late in the second, sixth, and twelfth cycles of treatment. ICG half-life was found to be extended in the adaptation phase only in response to Deposiston. ICG is recommended for time-related diagnosis of liver changes in women on hormonal contraceptives.

Indocyanine green (ICG) is an FDA-approved, strongly photo-absorbent/fluorescent probe that has been incorporated into a clinically-relevant PEGylated liposome as a flexible optoacoustic contrast agent platform. This study describes the engineering of targeted PEGylated liposome-ICG using the anti-MUC-1 "humanized" monoclonal antibody (MoAb) hCTM01 as a tumour-specific theranostic system. We aimed to visualise non-invasively the tumour accumulation of these MoAb-targeted liposomes over time in tumour-bearing mice using multispectral optoacoustic tomography (MSOT). Preferential accumulation of targeted PEGylated liposome-ICG was studied after intravenous administration in comparison to non-targeted PEGylated liposome-ICG using both fast growing (4T1) and slow growing (HT-29) MUC-1 positive tumour models. Monitoring liposomal ICG in the tumour showed that both targeted and non-targeted liposome-ICG formulations preferentially accumulated into the tumour models studied. Rapid accumulation was observed for targeted liposomes at early time points mainly in the periphery of the tumour volume suggesting binding to available MUC-1 receptors. In contrast, non-targeted PEGylated liposomes showed accumulation at the centre of the tumour at later time points. In an attempt to take this a step further, we successfully encapsulated the anticancer drug, doxorubicin (DOX) into both targeted and non-targeted PEGylated liposome-ICG. The engineering of DOX-loaded targeted ICG liposome systems present a novel platform for combined tumour-specific therapy and diagnosis. This can open new possibilities in the design of advanced image-guided cancer therapeutics. PMID:25445515

Erythrocyte-based nanoparticle platforms can offer long circulation times not offered by traditional drug delivery methods. We have developed a novel erythrocyte-based nanoparticle doped with indocyanine green (ICG), the only FDA-approved near-infrared chromophore. Here, we report on the absorption and fluorescence emission characteristics of these nanoparticles fabricated using ICG concentrations in the range of 161-323 μM. These nanoparticles may serve as biocompatible optical materials for various clinical imaging and phototherapeutic applications.

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer due in part to a lack of highly robust cytotoxic or molecular-based therapies. Recent studies investigating ligand-mediated Wnt/β-catenin signaling have highlighted its importance in pancreatic cancer initiation and progression, as well as its potential as a therapeutic target in PDAC. The small-molecule ICG-001 binds cAMP-responsive element binding (CREB)-binding protein (CBP) to disrupt its interaction with β-catenin and inhibit CBP function as a coactivator of Wnt/β-catenin-mediated transcription. Given its ability to inhibit Wnt/β-catenin-mediated transcription in vitro and in vivo, as well as its efficacy in preclinical models of colorectal cancer and other Wnt-driven diseases, we examined ICG-001 and its potential role as a therapeutic in PDAC. ICG-001 alone significantly inhibited anchorage-dependent and -independent growth of multiple PDAC lines, and augmented in vitro growth inhibition when used in combination with gemcitabine. ICG-001 had only variable modest effects on PDAC apoptosis and instead mediated PDAC growth inhibition primarily through robust induction of G₁ cell-cycle arrest. These effects, however, seemed decoupled from its inhibition of Wnt/β-catenin-mediated transcription. DNA microarrays performed on PDAC cells in the context of ICG-001 treatment revealed ICG-001 altered the expression of several genes with well-established roles in DNA replication and cell-cycle progression, including direct actions on SKP2 and CDKN1A. ICG-001 also significantly prolonged survival in an in vivo orthotopic xenograft model of PDAC, indicating ICG-001 or derived compounds that disrupt CBP activity are potentially useful small-molecule therapeutics for pancreatic cancer.

Virulence of the intracellular pathogen Rhodococcus equi depends on a 21.3-kb pathogenicity island located on a conjugative plasmid. To date, the only nonregulatory pathogenicity island-encoded virulence factor identified is the cell envelope-associated VapA protein. Although the pathogenicity islands from porcine and equine R. equi isolates have undergone major rearrangements, the virR operon (virR-icgA-vapH-orf7-virS) is highly conserved in both, suggesting these genes play an important role in pathogenicity. VirR and VirS are transcriptional regulators controlling expression of pathogenicity island genes, including vapA. Here, we show that while vapH and orf7 are dispensable for intracellular growth of R. equi, deletion of icgA, formerly known as orf5, encoding a major facilitator superfamily transport protein, elicited an enhanced growth phenotype in macrophages and a significant reduction in macrophage viability, while extracellular growth in broth remained unaffected. Transcription of virS, located downstream of icgA, and vapA was not affected by the icgA deletion during growth in broth or in macrophages, showing that the enhanced growth phenotype caused by deletion of icgA was not mediated through abnormal transcription of these genes. Transcription of icgA increased 6-fold within 2 h following infection of macrophages and remained significantly higher 48 h postinfection compared to levels at the start of the infection. The major facilitator superfamily transport protein IcgA is the first factor identified in R. equi that negatively affects intracellular replication. Aside from VapA, it is only the second pathogenicity island-encoded structural protein shown to play a direct role in intracellular growth of this pathogenic actinomycete. PMID:24549327

Light-induced inhibition of intracellular molecules holds great promise for a selective treatment of cancer and other diseases. Challenges for the targeting of intracellular proteins are the synthesis of effective photoimmuno-conjugates and their functional delivery inside living cells. In earlier studies we have shown, that photodynamic inactivation of the nuclear Ki-67 protein leads to an effective elimination of proliferating tumor cells. Here we show a selective treatment for EGFR and Ki-67 positive cancer cells after light-controlled delivery of indocyanine green (ICG) photo-immunoconjugates. The Ki-67 antibody TuBB-9, which recognizes an active state of the protein, was labeled with different ratios of ICG and encapsulated into immuno-liposomes that selectively deliver the conjugates to EGFR overexpressing cells. To overcome endosomal entrapment of the delivered agents, ovarian carcinoma cells were treated with the photosensitizer benzoporphyrin monoacid derivative (BPD) and irradiated first for endosomal escape of the TuBB-9-ICG constructs. 24 h after irradiation TuBB-9-ICG antibodies showed a relocalization from spots in the cytoplasm to the cell nucleus. A second irradiation of the delivered TuBB-9-ICG led to a significant elimination of cells after Ki-67 inactivation.

Incidents of intentional food contamination can produce ripple effects in consumers such as reduced trust and increased anxiety. In their postcrisis communication, food companies often direct the blame at the perpetrator in an effort to mitigate potential losses and regain consumer trust. The attempt to placate consumers may, in itself, potentially create psychological ripple effects in message readers. This study examined the interacting influence of two message characteristics: identity of the perpetrator of the crime (in-group/out-group membership), and the attribution of blame (reason why the perpetrator committed the crime), with message receiver characteristic (cultural identity) on psychological ripple effects such as blame, trust, anxiety, and future purchase intention. Results indicated that although group membership of the perpetrator was not significant in predicting outcomes for the organization, the attribution communicated in the message was. American message receivers blamed the organization more and trusted it less when personal dispositional attributions were made about the perpetrator. Asian message receivers blamed the organization more and trusted it less when situational attributions were made about the perpetrator. Lowered trust in the company and increased anxiety correlated with lower purchase intent for both American and Asian message receivers. Implications for crisis message design are discussed.

Responding to the recent work of Andrew Gamble, the article discusses the extent to which the British situation can be described in terms of crisis. It suggests that an essential element of crisis is that of political and social contestation, and explores the terms on which contestation is taking shape in and around British education.

En-face OCT acquired simultaneously with paired confocal ophthalmoscopic (CO) images provides unprecedented point-to-point correlation between surface and subsurface anatomy of the retina. An advanced prototype of a dual channel OCT/CO instrument was developed in terms of signal to noise ratio and image size. The system can operate in A, B and C-scan regimes. The design is such that there is a strict pixel to pixel correspondence between the OCT and confocal images. An extensive array of clinic pathologies were studied including macular degeneration, central serous retinopathy (CSR), macular hole, macular pucker, cystoid macular edema (CME), diabetic maculopathy, and macular trauma. We report observation of reoccurring patterns in the en-face OCT images which could be identified with different diseases. The system can also simultaneously produce en-face OCT and indocyanine green (ICG) fluorescence images where the same source is used to produce the OCT image and excite the ICG. The system is compact and assembled on a chin rest and it enables the clinician to visualise the same area of the eye fundus in terms of both en face OCT slices and ICG angiograms, displayed side by side. The images are collected by fast en-face scanning (T-scan) followed by slower scanning along a transverse direction and depth scanning. The system is capable of providing chosen OCT B-scans at selected points from the ICG image.

Sera of negroes of African origin and of indians, living in a malaria endemic village on the Pacific Coast of Colombia, were analyzed to see if they could block intraerythrocytic Plasmodium falciparum growth in vitro. A group of mestizos from a malaria-free city in Colombia was used as a negative control. Blood of each individual was studied for the presence of circulating parasites by thick and thin smears and their sera for antimalarial antibodies by IFAT and IRMA techniques. The inhibition of the intraerythrocytic growth induced by these sera was assessed by [3H]Hypoxanthine incorporation. All groups showed inhibitory activity independent of their exposure to malaria. Negro sera had the highest inhibitory activity even following the removal of antibody, and also the highest antimalarial antibody titers. The group of indians had reduced inhibitory activity and lower antibody titers compared to the negro sera. In the group of mestizos, who reported no malaria exposure, 14% had antibodies to asexual blood forms of P. falciparum and 60% induced significant inhibition. PMID:2283155

Indocyanine Green (ICG) is clinically used as a fluorescent dye for imaging purposes. Its rapid circulation kinetics and minimal toxicity has prompted investigation into ICG's utility as a photosentitizer for therapeutic applications. Traditionally, optically mediated tumor therapy has focused on photodynamic therapy, which employs a photochemical mechanism resulting from the absorption of low intensity CW laser light by localized photosensitizers such as Photofrin II, Benzoporphyrin Derivative (BPD), ICG. Treatment of cutaneous vascular malformations such as port-wine stains, on the other hand, is based on a photothermal mechanism resulting from the absorption of high intensity pulsed laser light by hemoglobin. In this study, we compared the effectiveness of combining photochemical and photothermal mechanisms during application of ICG in conjunction with laser irradiation with the intention that the combined approach may lead to a reduction in the threshold dose of pulsed laser light required to treat hypervascular malformations. The blood vessels in rabbit ears were used as an in vivo model for targeted vasculature. Irradiation of the ears with IR light (λ=785 nm, Δτ = 3 min, Io = 120 mW) was used to elicit photochemical damage, while photothermal damage was brought about using pulses from a ruby laser (λ=694 nm, τ = 3 ms) with different fluences. For the combined modality, photochemical damage was induced first and followed by photothermal irradiation. This modality was compared with photothermal irradiation alone. The effectiveness of each irradiation scheme was assessed using histopathological analysis. We present preliminary data that suggests that pretreatment with photodynamic therapy before photothermal coagulation results in more severe vascular damage with lower photothermal fluence levels. The results of this study provide the foundation work for further exploration of the therapeutic potentials of photochemical and photothermal effects during

We demonstrate the feasibility of mapping a sentinel lymph node (SLN) and urinary bladder by using modified single-walled carbon nanotubes (SWNTs) as a nonionizing photoacoustic (PA) contrast agent. To improve the PA sensitivity, indocyanine green (ICG) was conjugated with SWNTs and the optical absorption of SWNTs-ICG was enhanced by approximately four times compared to that of plain SWNTs at a concentration of 0.3 µM. In vivo PA imaging results showed that the SLN and bladder were clearly visualized due to accumulation of SWNTs-ICG. This implies that the SWNTs-ICG could be potentially utilized to identify SLNs in breast cancer patients and tracking vesicoureteral reflux in combination with PA imaging.

We recently reported construction of a new type of optical nano-construct composed of genome-depleted plant infecting brome mosaic virus (BMV) doped with Indocyanine green (ICG), an FDA-approved chromophore. We refer to these constructs as optical viral ghosts (OVGs) since only the capsid protein (CP) subunits of BMV remain to encapsulate ICG. To utilize OVGs as effective nano-probes in fluorescence imaging applications, their fluorescence quantum yield needs to be maximized. In this study, we investigate the effect of altering the CP to ICG mass ratio on the fluorescent quantum yield of OVGs. Results of this study provide the basis for construction of OVGs with optimal amounts of CP and ICG to yield maximal fluorescence quantum yield.

The influence of bacterial lectin on photochemically induced fat cell lipolysis was studied. Resulting capsules were tested for ICG absorption by optical spectra measurements. To separate released and encapsulated ICG supernatant was removed and capsules were redispered in pure deionized water. Supernatant and capsule suspension spectra were measured separately. It was also found that pretreatment of tissue by lectin leads to acceleration of lipolysis at photochemical treatment. The data obtained can be used to enhance efficiency of photochemical therapy.

Laser assisted vascular repair is a new optimized technique based on the use of ICG-infused chitosan patch to close a vessel wound, with or even without few supporting single stitches. We present an in vivo experimental study on an innovative end-to-end laser assisted vascular anastomotic (LAVA) technique, performed with the application of ICGinfused chitosan patches. The photostability and the mechanical properties of ICG-infused chitosan films were preliminary measured. The in vivo study was performed in 10 New Zealand rabbits. After anesthesia, a 3-cm segment of the right common carotid artery was exposed, thus clamped proximally and distally. The artery was then interrupted by means of a full thickness cut. Three single microsutures were used to approximate the two vessel edges. The ICG-infused chitosan patch was rolled all over the anastomotic site and welded by the use of a diode laser emitting at 810 nm and equipped with a 300 μm diameter optical fiber. Welding was obtained by delivering single laser spots to induce local patch/tissue adhesion. The result was an immediate closure of the anastomosis, with no bleeding at clamps release. Thus animals underwent different follow-up periods, in order to evaluate the welded vessels over time. At follow-up examinations, all the anastomoses were patent and no bleeding signs were documented. Samples of welded vessels underwent histological examinations. Results showed that this technique offer several advantages over conventional suturing methods: simplification of the surgical procedure, shortening of the operative time, better re-endothelization and optimal vascular healing process.

The current standard of care in determining the need to excise and graft a burn remains with the burn surgeon, whose clinical judgment is often variable. Prior work suggests that minimally invasive perfusion technologies are useful in burn prognostication. Here we test the predictive capabilities of Laser Doppler Imaging (LDI) and indocyanine green dye (ICG) angiography in the prediction of burn scarring 28 days after injury using a previously validated porcine burn model that shows vertical progression injury. Twelve female Yorkshire swine were burned using a 2.5 × 2.5 cm metal bar at variable temperature and application times to create distinct burn depths. Six animals (48 injuries total) each were analyzed with LDI or ICG angiography at 1, 24, 48, and 72 h following injury. A linear regression was then performed correlating perfusion measurements against wound contraction at 28 days after injury. ICG angiography showed a peak linear correlate (r(2)) of .63 (95% CI .34 to .92) at 48 h after burn. This was significantly different from the LDI linear regression (p < .05), which was measured at r(2) of .20 (95% CI .02 to .39). ICG angiography linear regression was superior to LDI at all timepoints. Findings suggest that ICG angiography may have significant potential in the prediction of long-term burn outcomes.

Atherosclerosis is a major cause of cardiovascular and cerebrovascular diseases that have high mortality and disability rates. Because of its unclear pathogenic mechanism and heterogeneous distribution feature, it is still a big challenge to achieve precise diagnosis and therapy of atherosclerosis at its early stage in vivo. Herein, we fabricated a new ICG@PEG-Ag2S nanoprobe by a simple self-assembly of DT-Ag2S QDs, amphipathic C18/PEG polymer molecules and ICG. The ICG@PEG-Ag2S nanoprobe showed relatively long blood retention and was selectively accumulated in the region of atherosclerotic plaque due to the lipophilicity of the C18 chain to the atherosclerosis microenvironment, and thus the atherosclerosis was real-time monitored by high contrast-enhanced photoacoustic (PA) imaging of ICG. Combining the high signal-to-noise ratio (SNR) and high spatial resolution fluorescence imaging of Ag2S QDs in the second near-infrared window (NIR-II) and related histological assessment in vitro, the feasibility of this new nanoprobe for atherosclerosis targeting in an Apoe(-/-) mouse model was verified. Additionally, hemolysis and coagulation assays of the ICG@PEG-Ag2S revealed its decent hemocompatibility and no histological changes were observed in the main organs of the mouse. Such a simple, multifunctional nanoprobe for targeting and PA imaging of atherosclerosis will have a great potential for future clinical applications. PMID:26853187

Organic dyes have found increasing use a s sensitizers in laser surgical procedures, due to their high optical absorbances. Little is known, however, about the nature of the degradation products formed when these dyes are irradiated with a laser. Previous work in our laboratories has shown that irradiation of polymeric and biological tissues with CO2 and Nd:YAG lasers produces a host of volatile and semivolatile by-products, some of which are known to be potential carcinogens. This work focuses on the identification of the chemical by-products formed by diode laser and Nd:YAG laser irradiation of indocyanine green (ICG) and carbon black based ink sensitized tissues, including bone, tendon and sheep's teeth. Samples were mounted in a 0.5-L Pyrex sample chamber equipped with quartz optical windows, charcoal filtered air inlet and an outlet attached to an appropriate sample trap and a constant flow pump. By-products were analyzed by GC/MS and HPLC. Volatiles identified included benzene and formaldehyde. Semi-volatiles included traces of polycyclic aromatics, arising from the biological matrix and inks, as well as fragments of ICG and the carbon ink components. The significance of these results will be discussed, including the necessity of using appropriate evacuation devices when utilizing lasers for surgical procedures.

This study documents the effect of players' dismissals on team performance in professional soccer. Our aim was to determine whether the punishment meted out for unacceptable player behaviour results in reduced team performance. The official web site of the German Soccer Association was used for coding data from games played in the first Bundesliga between the 1963 - 64 and 2003 - 04 (n = 41) seasons. A sample of 743 games where at least one red card was issued was used to test hypotheses derived from crisis theory (Bar-Eli & Tenenbaum, 1989a). Players' dismissals weaken a sanctioned team in terms of the goals and final score following the punishment. The chances of a sanctioned team scoring or winning were substantially reduced following the sanction. Most cards were issued in the later stages of matches. The statistics pertaining to outcome results as a function of game standing, game location, and time phases - all strongly support the view that teams can be considered conceptually similar to individuals regarding the link between stress and performance. To further develop the concept of team and individual psychological performance crisis in competition, it is recommended that reversal theory (Apter, 1982) and self-monitoring and distraction theories (Baumeister, 1984) be included in the design of future investigations pertaining to choking under pressure.

Near infrared intra-operative optical imaging is an emerging technique with clear implications for improved cancer surgery by enabling a more distinct delineation of the tumor margins during resection. This modality has the potential to increase the number of patients having a curative radical tumor resection. In the present study, a new uPAR-targeted fluorescent probe was developed and the in vivo applicability was evaluated in a human xenograft mouse model. Most human carcinomas express high level of uPAR in the tumor-stromal interface of invasive lesions and uPAR is therefore considered an ideal target for intra-operative imaging. Conjugation of the flourophor indocyanine green (ICG) to the uPAR agonist (AE105) provides an optical imaging ligand with sufficiently high receptor affinity to allow for a specific receptor targeting in vivo. For in vivo testing, human glioblastoma xenograft mice were subjected to optical imaging after i.v. injection of ICG-AE105, which provided an optimal contrast in the time window 6–24 h post injection. Specificity of the uPAR-targeting probe ICG-AE105 was demonstrated in vivo by 1) no uptake of unconjugated ICG after 15 hours, 2) inhibition of ICG-AE105 tumor uptake by a bolus injection of the natural uPAR ligand pro-uPA, and finally 3) the histological colocalization of ICG-AE105 fluorescence and immunohistochemical detected human uPAR on resected tumor slides. Taken together, our data supports the potential use of this probe for intra-operative optical guidance in cancer surgery to ensure complete removal of tumors while preserving adjacent, healthy tissue.

As one of 13 new `Centres of Excellence' awarded by the Norwegian Research Council with a 10-year funding schedule, the International Centre for Geohazards (ICG) was established at the Norwegian Geotechnical Institute (NGI), in January 2003. The Centre is formed through a co-operation between several institutions, which in addition to NGI are the Gelogical Survey of Norway (NGU), Norwegian Seismic Array (NORSAR), University of Oslo (UiO) and the Norwegian University for Science and Technology (NTNU). The Centre is located in the NGI building in Oslo, Norway. Funding is for 10 years, and the centre is staffed by researchers from the partner institutions, visiting scientists, post-doctoral fellows and Ph.D. students. With the ultimate goal of geohazard mitigation and preventing the loss of lives and damage to infrastructure and environment, key research topics of the Centre are: Unsaturated soils and mechanisms for precipitation-induced slides in steep slopes; Risk and vulnerability analysis for geohazards; Earthquake hazard, vulnerability and risk evaluation; Rock slope failures - models and risks; Landslides in soft clay slopes (quick clay), fjord margins and coastal zones; GIS applications to geohazards; SAR applications to geohazards; Slide dynamics and mechanics of disintegration; Tsunami modelling and prediction; and Offshore Geohazards. As prospecting for hydrocarbons move into increasingly deeper waters of the world's continental margins, research on offshore geohazard forms an important activity of the new centre. Main offshore geohazards include slope instability, effects of shallow gas and gas hydrates on the behaviour of seafloor sediments, mud volcanism and diapirism. Of these, slope instability is considered to be the major hazard, because of the potentially serious third party impact. The current offshore geohazards project within ICG consists of three main themes: Assessment of offshore geohazards (site surveys); Geophysical methods for offshore

Regular monitoring of brain perfusion at the bedside in neurointensive care is desirable. Currently used imaging modalities are not suited for constant monitoring and often require a transport of the patient. Noninvasive near infrared spectroscopy (NIRS) in combination with an injection of a safe dye (indocyanine green, ICG) could serve as a quasi-continuous brain perfusion monitor. In this work, we evaluate prerequisites for the development of a brain perfusion monitor using continuous wave (cw) NIRS technique. We present results from a high-resolution diffuse optical tomography (HR-DOT) experiment in humans demonstrating the separation of signals from skin from the brain. This technique can help to monitor neurointensive care patients on a regular basis, detecting changes in cortical perfusion in time.

Laser welding of microvessels provides several advantages over conventional suturing techniques: surgical times reduction, vascular healing process improvement, tissue damage reduction. We present the first application of biopolymeric patches in an in vivo laser assisted procedure for vessel repair. The study was performed in 20 New Zealand rabbits. After anesthesia, a 3-cm segment of the right common carotid artery was exposed and clamped proximally and distally. A linear lesion 3 mm in length was carried out. We used a diode laser emitting at 810 nm and equipped with a 300 μm diameter optical fiber. To close the cut, ICG-loaded chitosan films were prepared: chitosan is characterized by biodegradability, biocompatibility, antimicrobial, haemostatic and wound healing-promoting activity. ICG is an organic chromophore commonly used in the laser welding procedures to mediate the photothermal conversion at the basis of the welding effect. The membranes were used to wrap the whole length of the cut, and then they were welded in the correct position by delivering single laser spots to induce local patch/tissue adhesion. The result is an immediate closure of the wound, with no bleeding at clamps release. The animals were observed during follow-up and sacrificed after 2, 7, 30 and 90 days. All the repaired vessels were patent, no bleeding signs were documented. The carotid samples underwent histological examinations. The advantages of the proposed technique are: simplification of the surgical procedure and shortening of the operative time; good strength of the vessel repair; decreased foreign-body reaction, reduced inflammatory response and improved vascular healing process.

To overcome the intensive light scattering in the biological tissue, diffuse optical tomography (DOT) in the near infrared range for breast lesion detection usually is combined with other imaging modalities such as ultrasound, X-ray, and MRI, to provide guidance. However, the guided imaging modalities may depend on different contrast mechanics compared to the optical contrast in the DOT. As a result, they can't provide reliable guidance for diffuse optical tomography because some lesions may not be detectable by a non-optical modality but yet have high optical contrast. An imaging modality which can provide the guidance from optical contrast is desirable for DOT. In this paper, we present a system that combines diffuse optical tomography and photoacoustic tomography (PAT), to detect and characterize the deeply-seated targets embedded in a turbid medium. Photoacoustic tomography utilizes a short-pulsed laser beam to penetrate into tissue diffusively. Upon absorption of the light by the target, photoacoustic waves are generated and used to reconstruct, at ultrasound resolution, the optical absorption distribution that reveals optical contrast. The combined system used in the experiment combines a 64-channel photoacoustic system with a frequency-domain diffused optical system. To further improve the contrast, the exogenous contrast agent, indocyanine green (ICG) is used. Our experiment results show that the combined system can detect a tumormimicking phantom up to 2.5 cm in depth and 10 μM in concentration. Mice experiments also confirmed that the combined system can detect the tumor region and monitor the ICG uptake and washout in the tumor region. This method can potentially improve the accuracy to detect the small breast lesions or any lesions which are sensitive to the reference change, such as the lesions located on the chest wall.

The flight of 500,000-800,000 Rwandan refugees into the North Kivu region of Zaire in July, 1994, overwhelmed the world's response capacity. During the first month after the influx, almost 50,000 refugees died, an average crude mortality rate of 20-35 per 10,000 per day. This death rate was associated with explosive epidemics of diarrhoeal disease caused by Vibrio cholerae 01 and Shigella dysenteriae type 1. 3-4 weeks after the influx of refugees, acute malnutrition rates among children under 5 years old ranged between 18 and 23%. Children with a recent history of dysentery and those in households headed by women were at higher risk of malnutrition. A well-coordinated relief programme, based on rapidly acquired health data and effective interventions, was associated with a steep decline in death rates to 5 to 8 per 10,000 per day by the second month of the crisis. The prevention of high mortality due to diarrhoeal disease epidemics in displaced populations relies primarily on the prompt provision of adequate quantities of disinfected water, basic sanitation, community outreach, and effective case management of ill patients. In the emergency phase, effective, low-technology measures include bucket chlorination at untreated water sources, designated defaecation areas, active case-finding through community outreach, and oral rehydration. Relief agencies must place increased emphasis on training personnel in relevant skills to address major public health emergencies caused by population displacement. PMID:7646638

Clinical surveys show a continuous increase of antimicrobial resistance related to the frequency of the administrated medication. The antimicrobial photodynamic therapy (aPDT) is an effective adjuvant to reduce the need of antibiotics in dentistry, especially in periodontics. The antimicrobial effect of lightactivated photosensitizers in periodontics is demonstrated in clinical studies and case reports. Indocyanine green (ICG) as a new adjuvant shows the high potential of antiphlogistic and antimicrobial effects in combination with laser-light activation. In trying to answer the question of just how far the influence of temperature is acting on bacteria, this study was carried out. The influences of ICG at different concentrations (0.01 up to 1 mg/ml) in combination with a culture medium (brain-heart-infusion) and a bacteria culture (Streptococcus salivarius) at different optical densities (OD600 0.5 and 0.1) were investigated under laser-light activation. Laser activation was carried out with diode laser at 810 nm and two different power settings (100 mW/300 mW). The pulse repetition rate was 2 kHz. Taking account of the fiber diameter, distance and spot size on the sample surface, the applicated intensities were 6.2 and 18.7 W/cm2. Total irradiation time was 20 s for all meaurements. Transmitted laser power and temperature increase in the culture medium as well as in the bacteria culture were determined. Additionally the influence of ICG regarding bacterial growth and bactericidal effect was investigated in the bacteria culture without laser irradiation. Without laser, no bactericidal effect of ICG was observed. Only a bacteriostatic effect could be proved. In dependence of the ICG concentration and the applied intensities a temperature increase of ΔT up to 80°C was measured.

The abundance of heterogeneous biomedical data from a variety of sources demands the development of strategies to address data integration and management issues, so that the data can be used effectively in clinical practices and biomedical research. This research presents an Informatics Infrastructure for Integrating Clinical, Genomics and Environmental Data (ICGED) and provides a roadmap that envisions utilizing the clinical and biomedical resources in our case study. This work describes a data integration approach, proposed by ICGED, with a two-fold purpose: personalized medicine and biomedical data storage and sharing platform. It describes our experiences integrating disease specific clinical and genomics datasets with Data Integration and Analysis Tools (DIAT)--using Informatics for Integrating Biology and the Bedside, and discusses work in progress and future work for extending DIAT, and the development of Risk Assessment and Prediction Tools, Clinical Decision Support Systems and a Bioinformatics Data Warehouse.

Fluorescent tomography has been hindered by poor tissue penetration and weak signal which results in poor spatial resolution and quantification accuracy. Recently, it has been reported that activatable temperature responsive fluorescent probes which respond to focused ultrasound heating can improve the resolution and quantification of fluorescent tomography in deep tissue. This has lead to a new imaging modality, "Temperature-modulated fluorescent tomography." This technique relies on activatable thermo-sensitive fluorescent nanocapsules for whose fluorescence quantum efficiency is temperature dependent. Within a 4-5° C temperature range, the fluorescent signal increase more than 10-fold. In this molecular probe, Indocyanine Green (ICG) is encapsulated inside the core of a thermo-reversible pluronic micelle. Here we show the fluorescence response and temperature range of the nanocapsules which have been optimized for a higher temperature range to be used for in vivo animal imaging. We report on the feasibility of these temperature-sensitive reversible nanocapsules for in vivo applications by studying the pharmacokinetics in a subcutaneous mouse tumor model in vivo.

Metastasis is one of the major cancer complications, since the malignant cells detach from the primary tumor and reaches other organs or tissues. The sentinel lymph node (SLN) is the first lymphatic structure to be affected by the malignant cells, but its location is still a great challenge for the medical team. This occurs due to the fact that the lymph nodes are located between the muscle fibers, making it visualization difficult. Seeking to aid the surgeon in the detection of the SLN, the present study aims to develop a widefield fluorescence imaging device using the indocyanine green as fluorescence marker. The system is basically composed of a 780nm illumination unit, optical components for 810nm fluorescence detection, two CCD cameras, a laptop, and dedicated software. The illumination unit has 16 diode lasers. A dichroic mirror and bandpass filters select and deliver the excitation light to the interrogated tissue, and select and deliver the fluorescence light to the camera. One camera is responsible for the acquisition of visible light and the other one for the acquisition of the ICG fluorescence. The software developed at the LabVIEW® platform generates a real time merged image where it is possible to observe the fluorescence spots, related to the lymph nodes, superimposed at the image under white light. The system was tested in a mice model, and a first patient with tongue cancer was imaged. Both results showed the potential use of the presented fluorescence imaging system assembled for sentinel lymph node detection.

Superior cluneal nerve (SCN) entrapment neuropathy is a known cause of low back pain. Although surgical release at the entrapment point of the osteofibrous orifice is effective, intraoperative identification of the thin SCN in thick fat tissue and confirmation of sufficient decompression are difficult. Intraoperative indocyanine green video angiography (ICG-VA) is simple, clearly demonstrates the vascular flow dynamics, and provides real-time information on vascular patency and flow. The peripheral nerve is supplied from epineurial vessels around the nerve (vasa nervorum), and the authors now present the first ICG-VA documentation of the technique and usefulness of peripheral nerve neurolysis surgery to treat SCN entrapment neuropathy in 16 locally anesthetized patients. Clinical outcomes were assessed with the Roland-Morris Disability Questionnaire before surgery and at the latest follow-up after surgery. Indocyanine green video angiography was useful for identifying the SCN in fat tissue. It showed that the SCN penetrated and was entrapped by the thoracolumbar fascia through the orifice just before crossing over the iliac crest in all patients. The SCN was decompressed by dissection of the fascia from the orifice. Indocyanine green video angiography visualized the SCN and its termination at the entrapment point. After sufficient decompression, the SCN was clearly visualized on ICG-VA images. Low back pain improved significantly, from a preoperative Roland-Morris Questionnaire score of 13.8 to a postoperative score of 1.3 at the last follow-up visit (p < 0.05). The authors suggest that ICG-VA is useful for the inspection of peripheral nerves such as the SCN and helps to identify the SCN and to confirm sufficient decompression at surgery for SCN entrapment.

Multispectral optoacoustic tomography (MSOT) is a powerful modality that allows high-resolution imaging of photo-absorbers deep within tissue, beyond the classical depth and resolution limitations of conventional optical imaging. Imaging of intrinsic tissue contrast can be complemented by extrinsically administered gold nanoparticles or fluorescent molecular probes. Instead, we investigated herein generation of re-engineered clinically-used PEGylated liposomes incorporating indocyanine green (LipoICG) as a contrast strategy that combines materials already approved for clinical use, with strong photo-absorbing signal generation available today only from some metallic nanoparticles (e.g. gold nanorods). Using MSOT we confirmed LipoICG as a highly potent optoacoustic agent and resolved tissue accumulation in tumor-bearing animals over time with high-sensitivity and resolution using two tumor models of different vascularisation. We further showcase a paradigm shift in pharmacology studies and nanoparticle investigation, by enabling detailed volumetric optical imaging in vivo through the entire tumor tissue non-invasively, elucidating never before seen spatiotemporal features of optical agent distribution. These results point to LipoICG as a particle with significant advantageous characteristics over gold nanoparticles and organic dyes. PMID:25453969

Background. The most significant risk following major hepatectomy is postoperative liver insufficiency. Current preoperative assessment of the future liver remnant relies upon assumptions which may not be valid in the setting of advanced resection strategies. This paper reports the feasibility of the ALIIVE technique which assesses the liver remnant with ICG clearance intraoperatively during vascular exclusion. Methods. 10 patients undergoing planned major liver resection (hemihepatectomy or greater) were recruited. Routine preoperative assessment included CT and standardized volumetry. ICG clearance was measured noninvasively using a finger spectrophotometer at various time points including following parenchymal transection during inflow and outflow occlusion before vascular division, the ALIIVE step. Results. There were one case of mortality and three cases of posthepatectomy liver failure. The patient who died had the lowest ALIIVE ICG clearance (7.1%/min versus 14.4 ± 4.9). Routine preoperative CT and standardized volumetry did not predict outcome. Discussion/Conclusion. The novel ALIIVE technique is feasible and assesses actual future liver remnant function before the point of no return during major hepatectomy. This technique may be useful as a check step to offer a margin of safety to prevent posthepatectomy liver failure and death. Further confirmatory studies are required to determine a safety cutoff level. PMID:26106254

On November 27-28, 2012, the Kandilli Observatory and Earthquake Research Institute (KOERI) joined other countries in the North-eastern Atlantic, the Mediterranean and Connected Seas (NEAM) region as participants in an international tsunami response exercise. The exercise, titled NEAMWave12, simulated widespread Tsunami Watch situations throughout the NEAM region. It is the first international exercise as such, in this region, where the UNESCO-IOC ICG/NEAMTWS tsunami warning chain has been tested to a full scale for the first time with different systems. One of the systems is developed in the project Collaborative, Complex, and Critical Decision-Support in Evolving Crises (TRIDEC) and has been validated in this exercise among others by KOERI. KOERI, representing the Tsunami National Contact (TNC) and Tsunami Warning Focal Point (TWFP) for Turkey, is one of the key partners in TRIDEC. KOERI is responsible for the operation of a National Tsunami Warning Centre (NTWC) for Turkey and establishes candidate Tsunami Watch Provider (TWP) responsibilities for the Eastern Mediterranean, Aegean, Marmara and Black Seas. Based on this profound experience KOERI is contributing valuable requirements to the overall TRIDEC system and is responsible for the definition and development of feasible tsunami-related scenarios in the context of UNESCO-IOC ICG/NEAMTWS activities. However, KOERI's, most important input focuses on testing and evaluating the TRIDEC system according to specified evaluation and validation criteria in order to meet ICG/NEAMTWS requirements. The TRIDEC system will be implemented in three phases, each with a demonstrator. Successively, the demonstrators are addressing related challenges. The first and second phase system demonstrator, deployed at KOERI's crisis management room has been designed and implemented, firstly, to support plausible scenarios for the Turkish NTWC to demonstrate the treatment of simulated tsunami threats with an essential subset of a NTWC

Analysis of calls made to a northern Canadian Inuit crisis line in the territory of Nunavut between 1991 and 2001 revealed that the majority of users were adult females who called to discuss problems primarily related to relationships and loneliness/boredom. Younger callers tended to make prank calls. The volunteer staff used mostly empathetic…

A new sensitive fluorescence imaging system was developed for the real-time identification of sentinel lymph nodes (SLNs) in patients with early breast cancer. The purpose of this study was to evaluate the utility of a color charge-coupled device camera system for the intraoperative detection of SLNs and to determine its clinical efficacy and sensitivity in patients with operable breast cancer. We assessed a total of 168 patients diagnosed with or suspected of having early-stage breast cancer without metastasis in SLNs. The intraoperative detection of SLNs was performed using the conventional Indigo Carmine dye (indigotindisulfonate sodium) technique combined with a new Indocyanine green (ICG) imaging system (HyperEye Medical System: HEMS, MIZUHO IKAKOGYO, Japan) to map SLNs, in which the lymphatic vessels and SLNs were visualized transcutaneously with illuminating ICG fluorescence. Between January 2012 and May 2013, SLNs were successfully identified in all 168 patients (detection rate: 100%). By histopathology, the sensitivity was 93.8% for the detection of the metastatic involvement of SLNs (15 of 16 nodal-positive patients). After a median follow-up of 30.5 months, none of the patients presented with axillary recurrence. These results suggest that the HEMS imaging system is a feasible and effective method for the detection of SLNs in breast cancer. Furthermore, the HEMS device permitted the transcutaneous visualization of lymphatic vessels under light conditions, thus facilitating the identification and detection of SLNs without affecting the surgical procedure, together with a high sensitivity and specificity.

We investigated the kinetics of a bolus intravenous administrated normal saline by using near-infrared diffuse optical technique, and compared it with the kinetics of a non-targeted contrast agent indocyanine green (ICG) on small animal tumor model. Two-compartment model was used to fit the dynamic curves at early stage, which considered saline and ICG as either a negative or positive contrast agent. The purposes of the designed experiment reported here are to (1) study the effect of saline administration on optical pharmacokinetics; (2) investigate the possibility of using normal saline as contrast agent for the study of tumor pathophysiology. The study indicates that saline has different contrast mechanism as ICG, and saline can provide enough optical contrast for the tumor kinetic study.

The impedance cardiography (ICG) is widely used for beat-to-beat noninvasive evaluation of the left ventricular stroke volume and contractility. It implies the correct determination of the ejection start and end points and the amplitudes of certain peaks in the differentiated impedance cardiogram. An accurate identification of ejection onset by ICG is often problematic, especially in the cardiologic patients, due to peculiar waveforms. Using a simple theoretical model, we tested the hypothesis that two major processes are responsible for the formation of impedance systolic wave: (1) the changes in the heart geometry and surrounding vessels produced by ventricular contraction, which occur during the isovolumic phase and precede ejection, and (2) expansion of aorta and adjacent arteries during the ejection phase. The former process initiates the preejection wave WpE and the latter triggers the ejection wave WEj. The model predicts a potential mechanism of generating the abnormal shapes of dZ/dt due to the presence of preejection waves and explains the related errors in ICG time and amplitude parameters. An appropriate decomposition method is a promising way to avoid the masking effects of these waves and a further step to correct determination of the onset of ejection and the corresponding peak amplitudes from 'pathologically shaped' ICG signals.

Hypertensive crisis is an acute emergency requiring aggressive management. Its incidence has decreased in recent years but still is prevalent in the medical community. From review of past and present treatment regimens, the following recommendations can be considered. (1) In the treatment of malignant hypertension with associated CHF, sodium nitroprusside is still an excellent agent. It has a rapid onset of action and blood pressure can be easily titrated. Nitroglycerin is also another agent that can be used in this situation. (2) In the treatment of malignant hypertension with associated aortic dissection, trimethophan camsylate is the preferred agent. An alternative choice is the combination of nitroprusside and labetalol. (3) In the treatment of malignant hypertension with associated myocardial ischemia, an excellent choice is nitroglycerin. Labetalol also should be considered in this situation. (4) In the treatment of hypertension during pregnancy, hydralazine is still a good choice. Labetalol has also been shown to be efficacious. (5) In the treatment of malignant hypertension with associated cerebral ischemia, the following drugs should be considered: nitroprusside, nitroglycerin, and labetalol. The most important attribute of these agents is that they are nonsedating and rapid in onset. (6) In the treatment of postoperative hypertension the choices best suited are labetalol, enalapril, nitroprusside, and nitroglycerin. These agents are rapid in onset and all can be administered intravenously. PMID:2670090

We describe applications of silica (core)/gold (shell) nanoparticles and ICG dye to photothermal treatment of phantoms, biotissue and spontaneous tumor of cats and dogs. The laser irradiation parameters were optimized by preliminary experiments with laboratory rats. Three dimensional dynamics of temperature fields in tissue and solution samples was measured with a thermal imaging system. It is shown that the temperature in the volume region of nanoparticles localization can substantially exceed the surface temperature recorded by the thermal imaging system. We have demonstrated effective optical destruction of cancer cells by local injection of plasmon-resonant gold nanoshells and ICG dye followed by continuous wave (CW) diode laser irradiation at wavelength 808 nm.

Introduction Near infrared (NIR) technology has recently garnered much interest as a tool for intraoperative image–guided surgery in various surgical sub–disciplines. In urology, although nascent, NIR technology is also fostering much enthusiasm. This review discusses the two major fluorophores, indocyanine green (ICG) and methlyene blue (MB), with NIR guidance in experimental and clinical urology. The authors aim to illustrate and analyze the currently available initial studies to better understand the potential and practicability of NIR–guided imaging in the diagnosis and surgical outcome improvement. In the first part of the study we analyzed problems associated with sentinel lymph node biopsy, NIR–guided detection and imaging of tumors. Material and methods PubMed and Medline databases were searched for ICG and MB use in urological settings, along with data published in abstracts of urological conferences. Results Although NIR–guided ICG and MB are still in their initial phases, there have been significant developments in major domains of urology, including uro–oncological surgery: 1) sentinel lymph node biopsy, 2) detection and imaging of tumors Conclusions Much like in other fields of surgical medicine, the application of NIR technology in urology is at its early stages. Therefore, more studies are needed to assess the true potential and limitations of the technology. However, initial developments hint towards a pioneering tool that may influence various aspects of urology. PMID:25140227

Sentinel lymph node (SLN) mapping is emerging as an effective method for surgical staging of different gynecologic malignancies. Near-infrared (NIR) technology using a fluorescent dye such as indocyanine green (ICG) represents an interesting and feasible method for SLN mapping even in traditional open surgeries by applying video telescope operating microscope (VITOM) system technology. We report our preliminary experience in 12 women who underwent surgical nodal staging for early-stage vulvar and uterine or cervical cancer. Surgical and pathological outcomes are described, and the VITOM II ICG system's intraoperative image quality, handling and docking, and teaching value are assessed. The general impression of the surgical staff was that the VITOM II system is easy to use, and that the image quality of the anatomic structures is impressive. Traditional open SLN mapping with ICG appears to be easy to perform and reproducible, providing a new tool in the management of patients with gynecologic malignancies. Moreover, we believe that this technology has great potential as an operative teaching and learning modality for trainers for open surgical cases. Additional studies involving the VITOM system with a large sample size of patients are needed to confirm these promising results. PMID:26921484

Objective Various methods, including the indocyanine green (ICG) clearance test, the Child–Turcotte–Pugh score (CTP), model for end-stage liver disease (MELD), and MELD combined with serum sodium concentration (MELD-Na), have been used widely in liver function evaluation in patients with end-stage liver disease. In this study, we compared the ability of these methods to predict mortality in patients with decompensated hepatitis B cirrhosis. Methods A total of 98 patients with decompensated hepatitis B cirrhosis were included in this study and followed up for 12 months. The ICG-derived measurements (ICG-PDR, ICG-R15, EHBF), CTP, MELD, and MELD-Na were obtained within 2 days after patients’ admission and patients’ survival at 1, 3, 6, and 12 months was recorded. Receiver operating curve was used to evaluate the ability of these methods to predict mortality in these patients with decompensated hepatitis B cirrhosis. Results At 1 month, 3 months, 6 months and 12 months, the cumulative number of deaths and liver transplant recipients was 12 (12.2%), 17 (17.3%), 21 (21.4%) and 25 (25.5%), respectively. The ICG-derived measurements, CTP, MELD, and MELD-Na of nonsurvivors were significantly different compared with that in survivors. All methods yielded viable values in predicting short-term and medium-term prognosis for patients with decompensated hepatitis B cirrhosis, with most area under the curve exceeding 0.8. Moreover, the ICG-derived measurements showed a significant correlation with that of CTP, MELD, and MELD-Na. Conclusion All four methods, ICG clearance test, CTP, MELD, and MELD-Na, provided reliable prediction of mortality in patients with decompensated hepatitis B cirrhosis for both short-term and medium-term prognosis.

In cosmology we are facing the dark energy crisis: How can we survive huge vacuum energy, meanwhile living with tiny dark energy? For the solution to this crisis, we raise several clues and hints, in particular, supersymmetry and the double hierarchy, Mp-MSM-MDE (Planck-Standard Model-dark energy scales). These two clues naturally lead to a solution with a supersymmetry-breaking brane-world. The train of thought from the clues to the solution is elucidated.

We examined the effects of photodynamic hyperthemal therapy (PHT), which is a combination of photodynamic therapy (PDT) and hyperthermia (HT), on the apoptosis and cell cycle progression of murine melanoma B16F10 cells. The percentage of apoptotic cell was determined by flow cytometry using fluorescein isothiocyanate (FITC)-conjugated Annexin V and propidium iodide (PI) double staining. The cell cycle analysis was performed by PI staining with flow cytometry. The expression of cyclins and heat shock protein 70 (Hsp70) were examined by a Western blotting analysis. PHT induces death in B16F10 cells, and PHT-mediated apoptosis occurred acutely and persistently in vitro. Our study demonstrated that PHT using indocyanine green (ICG) and near infrared (NIR) light source induces apoptosis and G0/G1 cell cycle arrest in the B16F10 cells. PMID:22146339

Antibiotics are essential for both treating and preventing infectious diseases. Paradoxically, despite their importance as pillars of modern medicine, we are in danger of losing antibiotics because of the evolution and dissemination of resistance mechanisms throughout all pathogenic microbes. This fact, coupled with an inability to bring new drugs to market at a pace that matches resistance, has resulted in a crisis of global proportion. Solving this crisis requires the actions of many stakeholders, but chemists, chemical biologists, and microbiologists must drive the scientific innovation that is required to maintain our antibiotic arsenal. This innovation requires (1) a deep understanding of the evolution and reservoirs of resistance; (2) full knowledge of the molecular mechanisms of antibiotic action and resistance; (3) the discovery of chemical and genetic probes of antibiotic action and resistance; (4) the integration of systems biology into antibiotic discovery; and (5) the discovery of new antimicrobial chemical matter. Addressing these pressing scientific gaps will ensure that we can meet the antibiotic crisis with creativity and purpose. PMID:27622298

A naturalistic experiment tested the proposition that police time could be saved in nondangerous crisis intervention calls through the use of citizen participants. Results showed that police officers who used citizen intervention spent less time per call than officers who did not. However, police time was not saved in family disturbance calls. Family disturbance control group calls were rated by police as having a higher degree of physical danger present than other calls. PMID:3673956
``The history of science, to my knowledge,'' wrote Thomas Kuhn, describing the years just prior to the development of matrix and wave mechanics, ``offers no equally clear, detailed, and cogent example of the creative functions of normal science and crisis.'' By 1924, most quantum theorists shared a sense that there was much wrong with all extant atomic models. Yet not all shared equally in the sense that the failure was either terribly surprising or particularly demoralizing. Not all agreed, that is, that a crisis for Bohr-like models was a crisis for quantum theory. This paper attempts to answer four questions: two about history, two about memory. First, which sub-groups of the quantum theoretical community saw themselves and their field in a state of crisis in the early 1920s? Second, why did they do so, and how was a sense of crisis related to their theoretical practices in physics? Third, do we regard the years before 1925 as a crisis because they were followed by the quantum mechanical revolution? And fourth, to reverse the last question, were we to call into the question the existence of a crisis (for some at least) does that make a subsequent revolution less revolutionary?

We conducted a longitudinal survey of public response to the economic crisis to understand the trajectory of risk perception amidst an ongoing crisis. A nation-wide panel responded to seven surveys beginning in late September 2008 at the peak of the crisis and concluded in October 2009. At least 600 respondents participated in each survey, with 413 completing all seven surveys. Our online survey focused on perceptions of risk (savings, investments, retirement, job), negative emotions toward the financial crisis (sadness, anxiety, fear, anger, worry, stress), confidence in national leaders to manage the crisis (President Obama, Congress, Treasury Secretary, business leaders), and belief in one's ability to realize personal objectives despite the crisis. We employed latent growth curve modeling to analyze change in risk perception throughout the crisis. Our results suggest that, in general, people's perceptions of risk appear to decrease most rapidly during the initial phase of a crisis and then begin to level off. Negative emotion about the crisis was the most predictive of increased risk perception, supporting the notion of risk as feelings. Belief in one's ability to realize personal objectives was also predictive. Confidence in national leaders, however, was not predictive of perceived risk. Finally, our results demonstrate that groups may experience a crisis differently depending on a combination of personal characteristics such as gender, income, numeracy, and political attitude. Risk management and communication should work in sync with these mechanisms and differences across groups. PMID:22150242

The sovereign debt crisis in the euro area has not yet been solved and recent developments in Spain and Italy have further deteriorated the situation. In this paper we develop a new approach to analyze the ongoing Eurozone crisis. Firstly, we use Maximum Spanning Trees to analyze the topological properties of government bond rates’ dynamics. Secondly, we combine the information given by both Maximum and Minimum Spanning Trees to obtain a measure of market dissimilarity or disintegration. Thirdly, we extend this measure to include a convenient distance not limited to the interval [0, 2]. Our empirical results show that Maximum Spanning Tree gives an adequate description of the separation of the euro area into two distinct groups: those countries strongly affected by the crisis and those that have remained resilient during this period. The measures of market dissimilarity also reveal a persistent separation of these two groups and, according to our second measure, this separation strongly increased during the period July 2009-March 2012.

Modern crises present decision makers with many agonizing management choices. Very often a crisis manager is confronted with a plethora of conflicting information and given very little time to choose an appropriate course of action. Although contemporary methods of systems analysis have been used in attempts to organize data and clarify options, they have generally been of little use in presenting an accurate picture of an opponent's values and perceptions. Thus it is clear that we must now make use of the improved communications and technological devices at our disposal if crises are to be avoided or resolved with minimum damage. Our proposal to establish international model-oriented computer-assisted conferences is designed to promote greater cooperation and understanding among scientists and crisis managers of differing nations by enabling them to share images of themselves and one another. With better information and more rational options available, the chances of catastrophic misunderstanding or miscalculation can be meaningfully reduced. We have proposed a possible scenario for the initial implementation of such a system to combat famine, and hope that the same approach might be used in other areas over time. The ultimate goal is a system by which specialists of all persuasions cooperate so that international crises will be resolved on the bases of mutual benefits without resort to armed conflict.

Most medical malpractice cases are tried under the civil tort of negligence and are often triggered by adverse outcomes. These proceedings are aimed primarily at determining whether the conduct of a health care provider was reasonable. Such legal actions have mostly been subject to state jurisdiction. Increasingly, a number of factors are converging that are threatening the continued practice of medicine in some states and hence patients' access to care. These include higher amounts of monetary damages awarded to successful plaintiffs, consequent rising malpractice premiums, and the threatened economic insolvency of medical liability insurance carriers as a result of the broader economic downturn. The result is a serious public health dilemma. The national scope of the problem has been considered a crisis, which has prompted unprecedented federal legislative proposals directed toward providing new and preemptive parameters for capitated noneconomic damages, restrictions on certain civil procedures affecting lawsuit outcomes, and methods for attorney compensation, which some states have either not previously addressed or found unconstitutional. A survey of different states' problems and common issues should assist the reader in understanding the nature of the crisis and proposed solutions. PMID:17411514

We model the spreading of a crisis by constructing a global economic network and applying the susceptible-infected-recovered (SIR) epidemic model with a variable probability of infection. The probability of infection depends on the strength of economic relations between a given pair of countries and the strength of the target country. It is expected that a crisis that originates in a large country, such as the USA, has the potential to spread globally, such as the recent crisis. Surprisingly, we also show that countries with a much lower GDP, such as Belgium, are able to initiate a global crisis. Using the k-shell decomposition method to quantify the spreading power (of a node), we obtain a measure of 'centrality' as a spreader of each country in the economic network. We thus rank the different countries according to the shell they belong to, and find the 12 most central ones. These countries are the most likely to spread a crisis globally. Of these 12, only six are large economies, while the other six are medium/small ones, a result that could not have been otherwise anticipated. Furthermore, we use our model to predict the crisis spreading potential of countries belonging to different shells according to the crisis magnitude.

When you are ill and consult a physician for his or her expertise, many times laboratory testing is part of the clinical workup. This testing is critical to the physician’s ability to diagnose the patient’s condition. What if testing was not available … because there was no one to do the testing? Although seemingly far-fetched, this scenario could play itself out in the next ten years due to an impending manpower crisis in laboratory medicine. The profession of Medical Technology, also known as Clinical Laboratory Science, is experiencing a shortage of qualified individuals for a variety of reasons – not the least of which is the closure of almost 70% of the schools teaching this critical profession. Health care workers (HCW) rely on accurate and timely clinical laboratory results in order to make decisions for their patients. Because ∼ 70% of patient care decisions are based on clinical laboratory results, it is important to have a well-trained supply of laboratory professionals. This article will give an overview of the situation and the possible causes of this shortage, and pose challenges to our profession as to how this crisis can be averted. Visibility of this profession must be a prime focus of this effort in order for the population in general to be aware of the role Clinical Laboratory Scientists play in the health care consortium. This effort should begin early in the educational process, potentially as early as Middle School (junior high school), bringing awareness of the profession not only to students but to educators as well.

There is no "complete safety" in the medical treatment. Unavoidable events or human errors may frighten the patients' safety. Because of its characteristics, emergency medicine is one of the medical fields where treating the patients under the vast safety is difficult. It is inevitable to understand the background of human errors in the emergency medicine under the "SHEL" model. The implementation of the safety measures, such as minimum encounter, minimum probability, multiple detections, and minimum damage is helpful to prevent unfortunate outcomes. Since the emergency medicine treats the severely injured or critical ill patients, its daily works are the picture of the crisis management, and the most suitable environment to train the crisis management competence. The person in charge of crisis management of the institution should put the emergency department to practical use of medical staffs' crisis management training. PMID:26915239

The current economic crisis is not just another rough spell. Today's mix of urgency, high stakes, and uncertainty will continue even after the recession ends. The immediate crisis--which we will get through with policy makers' expert technical adjustments--sets the stage for a sustained, or even permanent, crisis, a relentless series of challenges no one has encountered before. Instead of hunkering down and relying on their familiar expertise to deal with the sustained crisis, people in positions of authority--whether they are CEOs or managers heading up a company initiative--must practice what the authors call adaptive leadership. They must, of course, tackle the underlying causes of the crisis, but they must also simultaneously make the changes that will allow their organizations to thrive in turbulent environments. Adaptive leadership is an improvisational and experimental art, requiring some new practices. Like Julie Gilbert, who overcame internal resistance to reorient Best Buy toward female purchasers, adaptive leaders get things done to meet today's challenges and then modify those things to thrive in tomorrow's world. They also embrace disequilibrium, using turbulence as an opportunity to build crucial new capacities, as Paul Levy did to rescue Beth Israel Deaconess Medical Center from a profound financial crisis. Finally, adaptive leaders, such as Egon Zehnder, the founder of an executive search firm, draw out the leadership skills that reside deep in the organization, recognizing the interdependence of all employees and mobilizing everyone to generate solutions.

Coastal areas are staggering under an onslaught of human activity. We are presently in the process of destroying 70 percent of the world`s 600,000 square kilometers of coral reefs, an ecosystem containing some 200,000 different species and rivaling tropical rain forests in biodiversity. A combination of pollution, habitat destruction, and gross overfishing has led to the collapse of major fisheries and paved the way for malnutrition and disease in regions where people fish for subsistence. Globally, little is being done to manage the crisis of our coasts. Management strategies, if they exist at all, often deal with economic development along a wafer-thin strip of coastal land. Resource degradation is ignored, and watershed management is mostly rhetoric. Although some 55 countries have drawn up coastal management plans, only a handful have been properly implemented. Coasts must be managed in an integrated manner that takes into account the full range of human activities. Initiating this process is costly, time-consuming, and difficult. Yet we have more than three decades of accumulated experience to draw on.
The crisis in American mining is discussed. The discussion focuses on the outlook for coal in the overall energy picture. Because of the Arab oil embargo of 1973, the Iranian disruption of 1979, and the tenfold increase in oil prices over the past decade, radical changes have taken place in energy supply and demand patterns. Two of the most important of these changes relate to investment. First, large investments have been made in energy-efficient plants, equipment, buildings, and vehicles. Their effect will restrain energy demand growth for the foreseeable future. Second, investments have been made in fuel-switching, from oil to coal and nuclear power. As a result the oil demand at the end of this century will be at approximately the same level as it is today. Natural gas demand is also likely to be flat. Coal demand, on the other hand, is expected to increase steadily over the long term. Recent conditions in the coal industry are reviewed, and a specific 10-year forecast is given.

Thyroid crisis, also known as thyroid storm, is a rare complication of thyrotoxicosis that results in a hypermetabolic and hyperadrenergic state. This condition requires prompt recognition and treatment because the mortality from thyroid crisis approaches 30%. Thyrotoxicosis alone will usually not progress to thyroid crisis. Thyroid crisis will typically be precipitated by some concomitant event such as infection, iodine-containing contrast agents, medications such as amiodarone, pregnancy, or surgery. Trauma is a rare precipitator of thyroid crisis. Several published studies have reported thyroid crisis resulting from blunt or penetrating neck trauma. Significant systemic trauma, such as motor vehicle accidents, has also been reported to precipitate thyroid crisis. It is very unusual for minor trauma to precipitate thyroid crisis. In the present study, we report the case of a patient who had incurred relatively minor maxillofacial trauma and developed thyroid crisis 2 weeks after the initial trauma. PMID:25085805

Past economic crises have increased the impact of communicable diseases especially on groups particularly vulnerable to the social and health consequences of the recession. However, it has been shown that the impact of these crises largely depends on the response of governments and the inhabitants of affected countries. We describe the consequences of the current crisis in the causal chain of infectious disease, including the response of the health system, and explore whether there is evidence of its impact in Spain. It is assumed that the possible effect of the crisis on living and working conditions is due to individual and social debt coupled with high unemployment as defining features of the crisis. We highlight the potential negative consequences of healthcare cuts on vulnerable populations, which have been partly excluded with the recent reform of health coverage. We compare mortality and morbidity data between two periods: before and after 2008, integrating, where possible, observed trends and institutional reports. Overall, no effect on infectious disease has been detected so far, although some signs of worsening, which could be compatible with the effects of the crisis, have been observed and need to be monitored and confirmed. We review the limitations of data sources that may not be sufficiently sensitive or up-to-date to detect changes that may require a latency period to become manifest. Instead of cutting resources, surveillance of these diseases should be improved, and an equitable social health response, which targets the population most affected by the crisis, should be guaranteed.

We live in troubling times. The economic crisis fills us with anxiety. Young, unemployed and throes to finish living worse fear that their parents are not able to take charge of the situation. What has happened to that Spain and Europe, less than four years ago seemed to land of opportunities for native and foreign, have become hostile territories? The economic crisis does not explain everything; It is only a symptom that the basis on which we were building the future were not as firm. It is true that the crisis has brought to bare the obscenity of speculative financial capitalism. It is also true that this crisis can be the great opportunity to build the world on a human and sustainable economic basis, i.e.,just the opposite of the current submission to the dictatorship of the financial markets. But the contemporary crisis has deep and extensive roots. I will refer to other crises, as important or more than the economic one, because to glimpse the future it is essential to carefully track the present and discover the "weak signals" the latent opportunities that await we become them realities.

To handle increased asaultive behavior on three psychiatric units while keeping staff and other patients safe, a Crisis Response Team was developed consisting of staff from psychiatry and officers from security. A written manual included the new policies and procedures and teaching content for verbal and physical deescalation techniques. A special inservice education program for assaultive crisis management was implemented. This model can be replicated in other areas of healthcare where it is necessary to deal with patients who lose verbal or physical control. PMID:11998671

The 1997 Indonesian financial crisis resulted in severe economic dislocation and political upheaval, and the detrimental consequences for economic welfare, physical health, and child education have been established in several studies. The crisis also adversely impacted the psychological well-being of the Indonesian population. Comparing responses of the same individuals interviewed before and after the crisis, we document substantial increases in several different dimensions of psychological distress among male and female adults across the entire age distribution. In addition, the imprint of the crisis can be seen in the differential impacts of the crisis on low education groups, the rural landless, and residents in those provinces that were most affected by the crisis. Elevated levels of psychological distress persist even after indicators of economic well-being such as household consumption had returned to pre-crisis levels, suggesting the deleterious effects of the crisis on the psychological well-being of the Indonesian population may be longer lasting than the impacts on economic well-being.

Vygotsky's The Historical Significance of the Crisis in Psychology (1926-1927) is an important text in the history and philosophy of psychology that has only become available to scholars in 1982 in Russian, and in 1997 in English. The goal of this paper is to introduce Vygotsky's conception of psychology to a wider audience. I argue that Vygotsky's argument about the "crisis" in psychology and its resolution can be fully understood only in the context of his social and political thinking. Vygotsky shared the enthusiasm, widespread among Russian leftist intelligentsia in the 1920s, that Soviet society had launched an unprecedented social experiment: The socialist revolution opened the way for establishing social conditions that would let the individual flourish. For Vygotsky, this meant that "a new man" of the future would become "the first and only species in biology that would create itself." He envisioned psychology as a science that would serve this humanist teleology. I propose that The Crisis is relevant today insofar as it helps us define a fundamental problem: How can we systematically account for the development of knowledge in psychology? I evaluate how Vygotsky addresses this problem as a historian of the crisis. PMID:22520196

Urgent action is needed to fight the alarming spread of HIV/AIDS that infected 1.3 million people in Southeast Asia last year alone, Malaysia's foreign minister said July 24, 2000. Syed Hamid said the Association of Southeast Asian Nations (ASEAN) should tackle at regional and national level an epidemic that was taking its most drastic toll among the region's youth. "HIV/AIDS not only represents a major public health and social problem but is a serious challenge to development as well," Syed Hamid told the opening ceremony of ASEAN's 33rd annual foreign ministers' meeting. The crisis requires commitment at the "highest political level," he said, warning that HIV/AIDS could become a transnational problem within the 10-member group. Foreign ministers have recommended their leaders discuss the crisis later this year at an informal summit in Singapore and hold a summit on HIV/AIDS in conjunction with the 7th ASEAN Summit in Brunei next year. "I think people recognized the importance and the adverse impacts on our social development," Syed Hamid told reporters later. "I think it is a real issue that we cannot run away from." Among ASEAN members, Thailand, Cambodia, and Myanmar have some of the highest infection rates in Asia of HIV, the virus that causes AIDS. PMID:12349742

Data derived from the Encuesta Nacional de Fecundidad y Salud (ENFES) confirm that overall levels of infant mortality in Mexico have been steadily declining. However, a more specific analysis furnishes evidence that this decline has occurred at varying rates within different social groups, reflecting an increase in social inequalities. The analytical strategy used in this article leads to three basic conclusions: (1) the impact of the economic crisis on infant mortality is reflected not in a reversal of the declining trend but an increase in social inequalities; (2) certain variables universally accepted as determinants of infant mortality, such as mother's education, seem nonsignificant for some social sectors; and (3) certain biodemographic characteristics assumed to have a uniform mortality-related behavior vary among sectors, suggesting that even these constants are determined by social factors.

The global economic and financial crisis is having and impact on the Italian healthcare system which is undergoing a devolution process from the central government to regions and where about one third of the regional governments (mainly in the central and southern part of the country) are facing large financial deficits. The paper briefly describes the current macro scenario and the main responses taken to face the crisis and highlights the downside risks of introducing "linear" cuts in the allocation of resources. While justified by the risk of a national debt default, present fiscal policies might increase inequalities in access to care, deteriorate overall health indicators and population wellbeing, and sharpen existing difference in the quality of care between regions. Preliminary evidence shows that the crisis is affecting the quality of nutrition and the incidence of psychiatric disorders. During this difficult financial situation Italy is also facing the risk of a major reduction in investments for preventive medicine, Evidence Based Medicine infrastructures, health information systems and physical capital renewal. This cost-cutting strategy may have negative long term consequences Also, important achievement in terms of limiting waiting lists, improving continuity of care and patients' centeredness, and promoting integration between social and health care may be negatively affected by unprecedented resources' cuts. It is essential that in such a period of public funding constraints health authorities monitor incidence of diseases and access to care of the most vulnerable groups and specifically target interventions to those who may be disproportionally hit by the crisis.

Second strikes are dominated by submarine launched missiles in the absence of defenses, but shift to aircraft at modest levels of defense. Defenses protect some retaliatory missiles, but not enough to retaliate strongly. With defenses, missiles should be vestigial and could be eliminated without penalty. Then aircraft could also be significantly reduced without impacting stability. The combination of parameters that maximizes cost effectiveness also maximizes midcourse effectiveness and crisis stability. 15 refs., 20 figs.

) and 95 in 2011, during the financial crisis (mean age 41.0 years, women 65%). There is an increase of suicide attempts by 35.71%. There were no statistically significant differences between the two periods regarding the gender and age of attempters. There was a statistically significant increase of unemployed (p=0.004), as well as of married/widowed/divorced (p=0.02) suicide attempters during the crisis. There was not statistically significant difference in the severity of suicide attempts before and during the economic crisis or the severity of psychopathology of the attempters. The financial crisis is probably associated with upward trend in attempted suicide of the Athens population. Most affected are those who are unemployed, married, widowed, divorced. Suicide prevention programs are essential for the accurate and timely identification and the immediate and effective management of this special high risk group of attempters during the financial crisis.

Starting in 2008 several European countries experienced a financial crisis. Historically, diseases whose prevention and treatment depend highly on the continuity of healthcare re-emerge during political and financial crises. Evidence suggests that the current financial crisis has had an impact on the health and welfare of Europeans and that population health status and morbidity as well as mortality patterns may change in the coming years. At the same time decisions about expenditure for health services may impact the ability of public health providers to respond. It is expected that the current crisis will further exacerbate socioeconomic and health inequalities and novel vulnerable groups will emerge in addition to existing ones. We review the available evidence and discuss how the current crisis may have an impact on vaccine-preventable diseases and influence vaccination coverage rates in Europe. PMID:25739315

The crisis of medical liability has resulted in drastic increases in insurance premiums and reduced access for patients to specialty care, particularly in areas such as obstetrics/gynecology, neurosurgery, and orthopaedic surgery. The current liability environment neither effectively compensates persons injured from medical negligence nor encourages addressing system errors to improve patient safety. The author reviews trends across the nation and reports on the efforts of an organization called "Doctors for Medical Liability Reform" to educate the public and lawmakers on the need for solutions to the chaotic process of adjudicating medical malpractice claims in the United States.

The classification and management of hypertensive crisis have been recently reviewed in the context of both European and American guidelines. The key points for proper blood pressure control in severe arterial hypertension are: 1 - Distinction between urgent intervention and emergencies 2 - Choice of the best drug(s) 3 - Choice of the correct route of administration. In patients with renal disease, beside the common causes of hypertension/ hypertensive crises, kidney-specific causes should be taken into account such as renal parenchymal hypertension, renovascular hypertension, sclerodermic crises, and preeclampsia.

This paper examines the impact in Australia of the global financial crisis on the baby boom cohort approaching later life. Data from national focus groups of people aged 50 to 64 years (N = 73), conducted in late 2008, found widespread but variable concern and uncertainty concerning work and retirement plans and experiences. A national survey (N = 1,009) of those aged 50 to 64 years in mid-2009 reported lower levels of financial satisfaction compared with other life domains; many planned to postpone retirement. Findings are interpreted in the context of policies and markets that differed significantly from those in the United States, notwithstanding the global nature of the financial crisis. PMID:23837628

Following a brief summary of research relating to midlife crisis, a theory of the midlife crisis is presented that is based on the philosophical insights of Plato and Heidegger: The emotional pain at midlife is associated with a collapse of a person's ontic field (relationships with others, to things, and to institutions) or a stagnation of a…

The research-based NETWASS prevention model aims to enable school staff to identify students experiencing a psychosocial crisis that could lead to severe targeted school violence and to initiate appropriate support measures. A detailed analysis of the adolescent psychosocial crisis is conducted at an early stage by evaluating possible warning behaviors, crisis symptoms, a student’s individual and social background, and resources. The model was implemented in 98 schools. During the project duration of seven months staff from 59 schools reported 99 cases of a student’s psychosocial crisis. Three experts conducted a content analysis of the reported qualitative data focusing on crisis symptoms of the students as well as the initiated measures. Results show a broad spectrum of risk factors, whereas aggressive behavior of students was reported most frequently. On the basis of theoretical assumptions, the reported cases were divided into three distinct risk groups. A total of eight high-risk cases were observed and reported by the school staff. The school staff mostly reacted to the student crisis by initiating resource-orientated measures, the expertise of child and youth therapists was mostly requested for the high risk cases. By describing the impact of cases and choice of measures undertaken, the study aims to give an overview of incidents schools as well as clinical psychologists and therapists are confronted with.

Reviews of public health emergency responses have identified a need for crisis leadership skills in health leaders, but these skills are not routinely taught in public health curricula. To develop criteria for crisis leadership in public health, published sources were reviewed to identify attributes of successful crisis leadership in aviation, public safety, military operations, and mining. These sources were abstracted to identify crisis leadership attributes associated with those disciplines and compare those attributes with crisis leadership challenges in public health. Based on this review, the following attributes are proposed for crisis leadership in public health: competence in public health science; decisiveness with flexibility; ability to maintain situational awareness and provide situational assessment; ability to coordinate diverse participants across very different disciplines; communication skills; and the ability to inspire trust. Of these attributes, only competence in public health science is currently a goal of public health education. Strategies to teach the other proposed attributes of crisis leadership will better prepare public health leaders to meet the challenges of public health crises. PMID:24274133

The U.S. oil and gas industry has been dramatically weakened by the recent oil price collapse. Domestic drilling activity reached a new post-World War II low during the summer of 1986. Given a weak, unstable oil price outlook, U.S. capability will continue to deteriorate. In the last year U.S. imports of foreign oil have risen significantly, and if market forces alone dominate, U.S. dependence is expected to rise from 32% in 1983 to the 50 to 70% level in the not-too-distant future. The 1973 oil embargo and the subsequent attempts to improve U.S. energy security vividly demonstrated the huge costs and long periods of time required to change our energy system. These facts, coupled with the nation's generally short-term orientation, suggest a strong likelihood of a new U.S. energy crisis in the early to middle 1990s. PMID:17775008

Α number of previous articles have dealt with the negative impact of the Greek Economic crisis on public health, including significant increases in major depression prevalence and suicide and homicide rates. The mentally ill seem to represent a vulnerable social group, with particular difficulties in this context. The number of compulsory assessments and involuntary admissions was recorded by reviewing patient records in the Department of Psychiatry of the University Hospital of Patras, through years 2006-2013. Compulsory assessments increased from 176 in 2006 to 262 in 2009 and 354 in 2013, representing a 48.86% and 101.13% increase in the first and the fifth year of economic crisis, respectively. The assessments resulted in 160 involuntary admissions in 2006, which escalated to 262 admissions (63.75% rise) in 2013. Even though a rise in involuntary placements could be attributed to other factors as well, it may also partly represent a not so evident side of the Greek economic crisis. PMID:27110884

In October 1957 the Soviet Union launched the first Earth-circling artificial satellite and the crisis that resulted led to numerous actions in the United States aimed at "remediating" a Cold War crisis. This included the establishment of a separate civilian space agency charged with the conduct of an official program of scientific and technological space exploration, consolidation of Department of Defense space activities, the passage of the National Defense Education Act, the creation of a Presidential Science Advisor, and a host of lesser actions. The politics of these changes is fascinating, and has been interpreted as an appropriate political response to a unique crisis situation. Interest groups, all for differing reasons, prodded national leaders to undertake large-scale efforts, something the president thought unnecessarily expensive and once set in place impossible to dismantle. But was the Sputnik crisis truly a crisis in any real sense? Was it made into one by interest groups who used it for their own ends? This paper will trace briefly some of the major themes associated with the IGY and Sputnik and describe the political construction of the crisis as it emerged in 1957- 1958. It will also discuss something about the transformation of federal science and technology that took place in the aftermath of the "crisis" and how it set in train a series of processes and policies that did not unravel until the end of the Cold War.

Children and adolescents in the United States and in many countries are projected to have shorter life spans than their parents, partly because of the obesity crisis engulfing the developed world. Exposure to electronic media is often implicated in this crisis because media use, including electronic game play, may promote sedentary behavior and increase consumption of high-calorie foods and beverages that are low in nutritional value. Electronic games, however, may increase children’s physical activity and expose them to healthier foods. We examine the role of electronic games in the pediatric obesity crisis and their contribution to more favorable health outcomes. PMID:23483693

Socioeconomic development in China has resulted in rapid urbanization, which includes a large amount of people making the transition from rural areas to cities. Many have speculated that this mass migration may have worsened the water crisis in many parts of the country. However, this study shows that the water crisis would be more severe if the rural-to-urban migration did not occur.

We apply the Random Matrix Theory and complex network techniques to 20 global financial indices and study the correlation and network properties before and during the financial crisis of 2008 respectively. We find that the largest eigenvalue deviate significantly from the upper bound which shows a strong correlation between financial indices. By using a sliding window of 25 days we find that largest eigenvalue represent the collective information about the correlation between global financial indices and its trend indicate the market conditions. It is confirmed that eigenvectors corresponding to second largest eigenvalue gives useful information about the sector formation in the global financial indices. We find that these clusters are formed on the basis of the geographical location. The correlation network is constructed using threshold method for different values of threshold θ in the range 0 to 0.9, at θ=0.2 the network is fully connected. At θ=0.6, the Americas, Europe and Asia/Pacific form different clusters before the crisis but during the crisis Americas and Europe are strongly linked. If we further increase the threshold to 0.9 we find that European countries France, Germany and UK consistently constitute the most tightly linked markets before and during the crisis. We find that the structure of Minimum Spanning Tree before the crisis is more star like whereas during the crisis it changes to be more chain like. Using the multifractal analysis, we find that Hurst exponents of financial indices increases during the period of crisis as compared to the period before the crisis. The empirical results verify the validity of measures, and this has led to a better understanding of complex financial markets.

When and how often to release information on television are important issues in crisis and emergency risk communication. There is a lot of crisis information, including warnings and news, to which people should have access, but most of it is not significantly urgent to interrupt the broadcasting of television programmes. Hence, the right timing for the release of crisis information should be selected based on the importance of the crisis and any associated communication requirements. Using recursive methods, this paper builds an audience coverage model of crisis information release. Based on 2007 Household Using TV (HUT) data for Hefei City, China, the optimal combination of broadcasting sequence (with frequencies between one and eight times) is obtained using the implicit enumeration method. The developed model is applicable to effective transmission of crisis information, with the aim of reducing interference with the normal television transmission process and decreasing the psychological effect on audiences. The same model can be employed for other purposes, such as news coverage and weather and road information. PMID:20572851

Last May, the New York State Dental Association and the New York State Dental Foundation convened the first "Oral Health Stakeholders' Summit on the Future of Special Needs Dentistry, Hospital Dentistry and Dental Education." The summit was chaired by David J. Miller, then NYSDA President Elect, and Carl H. Tegtmeier, then chair of the NYSDA Council on Dental Health Planning and Hospital Dentistry. It brought together experts, called to frame the issues and provide information necessary for a reasoned response. And it sought input from attendees to develop recommendations to ensure that patients with intellectual and developmental disabilities, as well as an aging population with Alzheimer's disease and dementia, have access to appropriate oral health care in the years ahead. Over 100 participants, representing dentistry, hospital training programs, third-party payers, state government offices and related patient support associations, attended the two-day event in Albany. They focused on the impact of reductions in funding, the transition of Medicaid services into a managed care model, a loss of service providers and the need for expanded training programs. They heard from speakers epresenting a broad spectrum of those involved in he oral health care of patients with intellectual and evelopmental disabilities, the Alzheimer's Association, dental educators and researchers, hospital dentistry and the benefits industry, whose presentations focused on a looming oral health crisis threatening access to dental care for patients with disabilities.

Minister of Health continued in 1982 to champion self-sufficiency despite a changed economic climate, but by early 1984 Costa Rica had to abandon its plan to wean the health sector from outside aid. In 1982 the health sector became the center of a nationwide debate. Representatives of the large agricultural export sector, who usually support free-market solutions to economic problems, lobbied for "reprivatization" of medical care. Those committed to expansion of the welfare state argued from the other extreme. The government offered concessions to both groups. The debate did end in 1986, most likely because of the overall easing of the economic crisis. The government needs to maintain state control over the health system while not exceeding its austerity budget and not reducing health services. PMID:3108317

The objectives of the SESPAS 2014 Report are as follows: a) to analyze the impact of the economic crisis on health and health-related behaviors, on health inequalities, and on the determinants of health in Spain; b) to describe the changes in the Spanish health system following measures to address the crisis and assess its potential impact on health; c) to review the evidence on the health impact of economic crises in other countries, as well as policy responses; and d) to suggest policy interventions alternative to those carried out to date with a population health perspective and scientific evidence in order to help mitigate the impact of the economic downturn on health and health inequalities. The report is organized in five sections: 1) the economic, financial and health crisis: causes, consequences, and contexts; 2) the impact on structural determinants of health and health inequalities; 3) the impact on health and health-related behaviors, and indicators for monitoring; 4) the impact on health systems; and 5) the impact on specific populations: children, seniors, and immigrants. There is some evidence on the relationship between the crisis and the health of the Spanish population, health inequalities, some changes in lifestyle, and variations in access to health services. The crisis has impacted many structural determinants of health, particularly among the most vulnerable population groups. Generally, policy responses on how to manage the crisis have not taken the evidence into account. The crisis may contribute to making public policy vulnerable to corporate action, thus jeopardizing the implementation of healthy policies. PMID:24863987

Objective To systematically identify, critically appraise, and synthesise empirical studies about the impact of the 2008 financial crisis in Europe on health outcomes. Design Systematic literature review. Data sources Structural searches of key databases, healthcare journals, and organisation based websites. Review methods Empirical studies reporting on the impact of the financial crisis on health outcomes in Europe, published from January 2008 to December 2015, were included. All selected studies were assessed for risk of bias. Owing to the heterogeneity of studies in terms of study design and analysis and the use of overlapping datasets across studies, studies were analysed thematically per outcome, and the evidence was synthesised on different health outcomes without formal meta-analysis. Results 41 studies met the inclusion criteria, and focused on suicide, mental health, self rated health, mortality, and other health outcomes. Of those studies, 30 (73%) were deemed to be at high risk of bias, nine (22%) at moderate risk of bias, and only two (5%) at low risk of bias, limiting the conclusions that can be drawn. Although there were differences across countries and groups, there was some indication that suicides increased and mental health deteriorated during the crisis. The crisis did not seem to reverse the trend of decreasing overall mortality. Evidence on self rated health and other indicators was mixed. Conclusions Most published studies on the impact of financial crisis on health in Europe had a substantial risk of bias; therefore, results need to be cautiously interpreted. Overall, the financial crisis in Europe seemed to have had heterogeneous effects on health outcomes, with the evidence being most consistent for suicides and mental health. There is a need for better empirical studies, especially those focused on identifying mechanisms that can mitigate the adverse effects of the crisis. PMID:27601477

This article describes the history and the prevailing orientations of group psychotherapy in Italy (psychoanalytically oriented, psychodrama, CBT groups) and particularly group analysis. Provided free of charge by the Italian health system, group psychotherapy is growing, but its expansion is patchy. The main pathways of Italian training in the different group psychotherapy orientations are also presented. Clinical-theoretical elaboration on self development, psychopathology related to group experiences, and the methodological attention paid to objectives and methods in different clinical groups are issues related to group therapy in Italy. Difficulties in the relationship between research and clinical practice are discussed, as well as the empirical research network that tries to bridge the gap between research and clinical work in group psychotherapy. The economic crisis in Italy has led to massive cuts in health care and to an increasing demand for some forms of psychological treatment. For these reasons, and because of its positive cost-benefit ratio, group psychotherapy is now considered an important tool in the national health care system to expand the clinical response to different forms of psychological distress. PMID:26401793
The Commonwealth of Puerto Rico is an organized nonincorporated territory of the United States with a population of more than 3.5 million U.S. citizens. The island has been the focus of much recent attention due to the recent default on its debt (estimated at more than $70 billion), high poverty rates, and increasing unemployment. Less attention, however, has been given to the island's healthcare system, which many believe is on the verge of collapsing. Healthcare makes up 20% of the Puerto Rican economy, and this crisis affects reimbursement rates for physicians while promoting the disintegration of the island's healthcare infrastructure. A major contributor relates to a disparity in federal funding provided to support the island's healthcare system when compared with that provided to the states in the mainland and Hawaii. Puerto Rico receives less federal funding for healthcare than the other 50 states and the District of Columbia even though it pays its share of social security and Medicare taxes. To make matters worse, the U.S. Center for Medicaid and Medicare Services is planning soon to implement another 11% cut in Medical Advantage reimbursements. This disparity in support for healthcare is considered responsible for ∼$25 billion of Puerto Rico's total debt. The impact of these events on the health of Puerto Ricans in the island cannot be entirely predicted, but the loss of healthcare providers and diminished access to care are a certainty, and quality care will suffer, leading to serious implications for those with chronic medical disorders including respiratory disease.

The present article analyzes the impact of the economic crisis on food consumption in Spain, the most affected social profiles, and the consequences of changing patterns of food consumption on health. This article is based on official reports and previous empirical studies. The crisis has affected diet and food consumption. Families are attempting to spend less money on food. Food insecurity is rising and the most affected groups are those spending a higher proportion of their income on food. Cuts in food spending run parallel with unhealthy eating habits that encourage obesity. Consequently, the crisis contributes to undermining the right to a healthy diet, recognized by the International Covenant on Economic, Social and Cultural Rights of the United Nations. PMID:24863995
In the wake of the financial crisis, sovereign debt crisis has emerged and is severely affecting some countries in the European Union, threatening the viability of the euro and even the EU itself. This paper applies recent developments in econophysics, in particular the minimum spanning tree approach and the associate hierarchical tree, to analyze the asynchronization between the four most affected countries and other resilient countries in the euro area. For this purpose, daily government bond yield rates are used, covering the period from April 2007 to October 2010, thus including yield rates before, during and after the financial crises. The results show an increasing separation of the two groups of euro countries with the deepening of the government bond crisis.

This research explores the transformation of rape crisis centers and whether directors, staff, interns, and volunteers see changes as beneficial or detrimental to rape crisis centers and the victims they serve. Data from 63 interviews with directors, staff, interns, and volunteers from six rape crisis centers located in four East Coast states indicate that although centers may have been formed for different reasons depending on when they opened, all have become more professional, rely less on volunteers, engage in more collaboration with other agencies, and have largely abandoned their traditional activism agenda. Traditional activism through political protests and membership in consciousness raising groups has been replaced by community education and outreach. Some of these changes are viewed as positive whereas others are viewed as negative. PMID:22083657

The financial crisis in Europe has posed major threats and opportunities to health. We trace the origins of the economic crisis in Europe and the responses of governments, examine the effect on health systems, and review the effects of previous economic downturns on health to predict the likely consequences for the present. We then compare our predictions with available evidence for the effects of the crisis on health. Whereas immediate rises in suicides and falls in road traffic deaths were anticipated, other consequences, such as HIV outbreaks, were not, and are better understood as products of state retrenchment. Greece, Spain, and Portugal adopted strict fiscal austerity; their economies continue to recede and strain on their health-care systems is growing. Suicides and outbreaks of infectious diseases are becoming more common in these countries, and budget cuts have restricted access to health care. By contrast, Iceland rejected austerity through a popular vote, and the financial crisis seems to have had few or no discernible effects on health. Although there are many potentially confounding differences between countries, our analysis suggests that, although recessions pose risks to health, the interaction of fiscal austerity with economic shocks and weak social protection is what ultimately seems to escalate health and social crises in Europe. Policy decisions about how to respond to economic crises have pronounced and unintended effects on public health, yet public health voices have remained largely silent during the economic crisis.

The surprising social phenomena of the Arab Spring and the Occupy Wall Street movement posit the question of whether the active role of committed groups may produce political changes of significant importance. Under what conditions are the convictions of a minority going to dominate the future direction of a society? We use a Cooperative Decision Making (CDM) model to study the effect of committed minorities on group behavior in time of crisis. The CDM model has been shown to generate consensus through a phase-transition process that at criticality establishes long-range correlations among the individuals within a model society. In a condition of high consensus, the correlation function vanishes, thereby making the network recover the ordinary locality condition. However, this state is not permanent and times of crisis occur when there is an ambiguity concerning a given social issue. The correlation function within the cooperative system becomes similarly extended as it is observed at criticality. This combination of independence (free will) and long-range correlation makes it possible for very small but committed minorities to produce substantial changes in social consensus.

The last six years the global community is facing an economic crisis that first appeared in USA. This crisis has a lot of impacts especially in health sector. Unemployment, job insecurity and the loss of disposable income have a significant impact in health too. The main objective of this research was to investigate the quality of life of the general population in Greece during the financial crisis. To collect the data it has been used the Greek version of Short Form (36) Health Survey (SF-36v2). In general, income, level of education, cohabitation and parenthood had a significant impact in quality of life. As a conclusion, unemployed participants' score was lower in the entire dimensions and in the two summary scales too. PMID:26152994

There is an epistemological crisis in genomics. At issue is what constitutes scientific knowledge in genomic science, or systems biology in general. Does this crisis require a new perspective on knowledge heretofore absent from science or is it merely a matter of interpreting new scientific developments in an existing epistemological framework? This paper discusses the manner in which the experimental method, as developed and understood over recent centuries, leads naturally to a scientific epistemology grounded in an experimental-mathematical duality. It places genomics into this epistemological framework and examines the current situation in genomics. Meaning and the constitution of scientific knowledge are key concerns for genomics, and the nature of the epistemological crisis in genomics depends on how these are understood. PMID:19440447
