A semi-Markov model with pathologies for Long-Term Care Insurance

Most Long-Term Care (LTC) Insurance products rely on definitions for functional disability based on the Activities of Daily Living (ADL). While functional disability may reflect the level of care required by the insured life, it is not on its own a good predictor of lifespan in LTC, which strongly depends on the underlying pathology responsible for disability. Indeed, cancer and respiratory diseases are associated with extremely short lifespan while dementia and neurological diseases make for much longer claims. Pathologies are therefore responsible for heterogeneity in the data, which makes estimation of mortality in LTC a difficult issue. As a consequence the associated literature is still scarce. In this paper, we study the mortality in LTC associated with 4 different groups of pathologies: cancer, dementia, neurological diseases and other causes based on data from a French LTC portfolio. We consider a semi-Markov framework, where mortality in LTC depends on both age at claim inception and time already spent in LTC. We first derive the incidence rate in LTC and mortality rate associated with each group of pathologies and for both males and females. To do so, we rely on local likelihood methods that we apply directly to transition intensities of the model. We then combine those transition intensities to get a second-step estimator of the overall mortality in LTC, which proves more accurate than a direct estimate regardless of the pathology. Finally our results indicates that the peak of mortality following entry in LTC observed in the data is mostly due to the cancer group.
AtomicNet: a novel approach to identify the crystal structure of each simulated atom

The study of crystal structure in the process of plastic deformation is essential to analyse the properties of materials and help to understand the deformation mechanism. With the rapid development of computer hardware and algorithms, great efforts have been paid for atomic simulation with computer science. However, most existing methods can only identify known structures in advance and consider unknown structure as unrecognized ones. In this work, we propose a method to identify crystal structure among atomistic simulations of crystalline materials. First, we develop a new characterization to describe each atom’s local space information, i.e. local spatial characteristics and utilize mutual information to simplify the characteristics. Then, the multi-layer perceptron neural network is used for the classification on the simplified characteristics. With the proposed method, we can not only identify the crystal structures of the surface of atoms, but also obtain the value of probability of each crystal structure. Our work provides significant insights for finding new mechanisms in structure transformation in material science field.
The microbiology of chronic osteomyelitis in a developing world setting

OBJECTIVES: The primary aim of this study was to identify the microorganisms that cause chronic osteomyelitis in a developing world clinical setting and to characterise the antibiotic sensitivity profile of these pathogens. Furthermore, we aimed to determine whether the causative organisms vary in relation to physiological status of the host, the HIV status of the patient or the cause of the infection (post-traumatic, post-operative and haematogenous. METHODS: We performed a retrospective review of consecutive adult patients treated curatively for chronic osteomyelitis of long bones, over a two-year period. Patient charts were reviewed and data extracted in respect of patient demographics, the cause of infection, physiological status of the host in accordance with the Cierny and Mader classification, HIV status, surgical treatment strategy and causative organism. RESULTS: A total of 108 organisms were identified in the 60 patients included in the study. Multiple organism were cultures in 45% of patients, a single Gram-positive organism in 22% and a single Gram-negative organism in 26% of patients. In four cases (7%) no causative organism was cultured. The most prevalent organisms were Enterobacteriaceae (34%), Staphylococcus spp. (29%), Pseudomonas aeruginosa (11%), and Enterococcus spp. (9%). Many isolates were found to be resistant to commonly used empirical anti-microbial agents. Seventy per cent of Enterobacteriaceae spp. were resistant to either cefuroxime and/or ampicillin-clavulanic acid. Seventy-seven per cent of Staphylococcus aureus isolates were susceptible to cloxacillin. More than 50% of Pseudomonas aeruginosa strains were resistant to meropenem, imipenem, piperacillin-tazobactam or cefepime. There was a significant association between the aetiology of the infection and the microorganisms involved (p-value < 0.01). The bacterial pathogen profile was, however, not associated with the physiological status of the host (p=0.22) or the HIV status of the patient. CONCLUSION: While the majority of haematogenous chronic osteomyelitis still involved a solitary Gram-positive organism, the incidence of Gram-negative infections was found to be higher than previously reported. Contiguous chronic osteomyelitis was mostly polymicrobial in nature and solitary infections involving a Gram-negative organism was most common in the post-traumatic group. The bacterial pathogen did not vary in relation to the HIV status of the patient or the physiological status of the host.
Gender implications for survival in South Asia.

Health status and life expectancy have improved and increased respectively in India. Males have however made the greatest strides forward with the position of women deteriorating relative to men over the period 1900-1970. For the age group under-1 year to late 30s females face higher mortality than males. Following this period steeply rising male mortality minimized the disparity. In the early years through age 10 sex and age segregation within the traditional peasant family leads to health treatment differentials between boys and girls. Greater resources are invested in caring for male offspring. Later over ages 20-30 years women suffer comparatively inadequate nutritional input in face of the extra strains of pregnancy childbirth lactation and menstruation. Factors supporting this differential treatment nutrition and subsequent mortality are however being eroded by education waning subsistence production and developing female autonomy. Note is made that this latter factor has thus far done more to reduce overall child mortality than to reduce differential mortality according to gender. It may also be noted that a females chances of survival depend more upon the general mortality level in her place of residence than her gender.
A Ka-Band Wideband Dual-Polarized Magnetoelectric Dipole Antenna Array on LTCC

A Ka-band wideband dual-polarized magnetoelectric (ME) dipole antenna with the feeding structure consisting of two orthogonal L-shaped probes with different heights is presented based on the low-temperature cofired ceramic (LTCC) technology. A simulated overlapped impedance bandwidth of 42.5% is achieved together with an isolation of higher than 24 dB between the two input ports and stable radiation characteristics over the operating band. By combining the radiating elements with a single-layered feed network composed of microstrip lines, a $4\times 4$ dual-polarized ME dipole antenna array is designed, fabricated, and measured. An overlapped impedance bandwidth of 45% that can cover the entire Ka-band, a gain up to 16.1 dBi, and stable symmetrical radiation patterns in the two orthogonal planes with cross polarization of less than −15 dB are experimentally confirmed. With advantages of the compact geometry, wide operating band, and promising radiation performance, the proposed antenna array with dual polarization would be attractive for millimeter-wave wireless applications in Ka-band.
Distributed output‐feedback finite‐time tracking control of nonaffine nonlinear leader‐follower multiagent systems

The distributed output‐feedback tracking control for a class of networked multiagents in nonaffine pure‐feedback form is investigated in this article. By introducing a low‐pass filter and some auxiliary variables, we first transform the nonaffine system into the affine form. Then, the finite‐time observer is designed to estimate the states of the newly derived affine system. By applying the fraction dynamic surface control approach and the neural network‐based approximation technique, the distributed output‐feedback control laws are proposed and it is proved that the tracking errors converge to an arbitrarily small bound around zero in finite time. Finally, some simulation examples are provided to confirm the effectiveness of the developed method.
Mining of Primary Healthcare Patient Data with Selective Multimorbid Diseases

Despite a large volume of research on the prognosis, diagnosis and overall burden of multimorbidity, very little is known about socio-demographic characteristics of multimorbid patients. This thesis aims to analyze the socio-demographic characteristics of patients with multiple chronic conditions (multimorbidity), focusing on patient groups sharing the same combination of diseases. Several methods were explored to analyze the co-occurrence of multiple chronic diseases as well as the associations between socio-demographics and chronic conditions. These methods include disease pair distributions over gender, age groups and income level quintiles, Multimorbidity Coefficients for measuring the concurrence of disease pairs and triples, and k−modes clustering to examine the demographics of patients with the same chronic condition. The experiments suggest that patient income quintile is not associated with multimorbidity rates, although gender and age group may play an important role in prevalence of multimorbidity and diagnosis of certain disease combinations.
Co-occurrence Networks do not Support Identification of Biotic Interactions

We assess a body of work that has attempted to use co-occurrence networks to infer the existence and type of biotic interactions between species. Although we see considerable interest in the approach as an exploratory tool for understanding patterns of co-occurrence of species, we note and describe numerous problems in the step of inferring biotic interactions from the co-occurrence patterns. These problems are both theoretical and empirical in nature, and limit confidence in inferences about interactions rather severely. We examine a series of examples that demonstrates striking discords between interactions inferred from co-occurrence patterns and previous experimental results and known life-history details.
Níveis Elevados de Netrina-1 e IL-1β em Mulheres Idosas com SCA: Pior Prognóstico no Acompanhamento de Dois Anos

Resumo Fundamento Vários marcadores têm sido avaliados quanto a um potencial impacto nas decisões clínicas ou na predição de mortalidade na síndrome coronariana aguda (SCA), incluindo Netrina-1 e IL-1β. Objetivo Examinamos o valor prognóstico de Netrina-1 e IL-1β em pacientes com SCA (2 anos de acompanhamento). Métodos Avaliamos Netrina-1, IL-1β e outros fatores de risco em amostras de soro de 803 pacientes. Curvas de Kaplan-Meier e regressão de Cox foram usadas para análise de óbito por todas as causas, óbito por doenças cardiovasculares (DCV) e desfecho combinado de infarto agudo do miocárdio (IAM) fatal ou novo IAM não fatal, considerando p < 0,05. Resultados Houve 115 óbitos por todas as causas, 78 óbitos por DCV e 67 eventos no desfecho combinado. Níveis de Netrina-1 acima da mediana (> 44,8 pg/mL) foram associados a pior prognóstico (óbito por todas as causas e por DCV) em mulheres idosas, mesmo após o ajuste do modelo (HR: 2,08, p = 0,038 e HR: 2,68, p = 0,036). Níveis de IL-1β acima da mediana (> 13,4 pg/mL) em mulheres idosas foram associados a risco aumentado para todos os desfechos após o ajuste (todas as causas - HR: 2,03, p = 0,031; DCV - HR: 3,01, p = 0,013; desfecho combinado - HR: 3,05, p = 0,029). Para homens, não foram observadas associações entre Netrina-1 ou IL-1β e os desfechos. Conclusão Níveis séricos elevados de Netrina-1 e IL-1β mostraram associação significativa com pior prognóstico em idosas do sexo feminino. Eles podem ser úteis como indicadores prognósticos em SCA.

Synthesis of Yttrium and Cobalt Doped Bismuth Ferrite Nanoparticles for Electrical and Magnetic Properties

Abstract A series of Yttrium (Y) and Cobalt (Co) co-doped bismuth ferrite (BFO) ceramics (Bi1-xYxFe1-yCoyO3) were fabricated by sol-gel method. The precursors used are [Bi(NO3)3.5H2O], [Fe(NO3)3.9H2O], [Y(NO3)3.6H2O] and [Co(NO3)2.6H2O]. X-ray diffraction (XRD) pattern confirms the formation of the pure phase bismuth ferrite (BFO) after annealing at 600 C for 2 hrs. The chemical bonding between Fe-O and Bi-O were identified by Fourier Transform Infrared Spectroscopy (FTIR) analysis. The electric polarization, magnetic properties and dielectric properties of the doped samples were enhanced with increasing content of Y and Co.

A prospective study to evaluate the efficacies of low volume and high volume caudal epidural steroid injections in the treatment of lumbar degenerative disc disease

Background: To evaluate the efficacy of low volume corticosteroid injections in the treatment of radiculopathy associated with lumbar degenerative diseases by comparing with that of conventional high-volume injection and appreciate the advantages of the technique. Study was a prospective comparative study. Setting was the operating room. Methods: 52 patients, they were randomized into two groups. Among them, 27 had undergone caudal epidural steroid injection (CESI) with low volume and 25 with high volume injections of triamcinolone. Intervention of the study was caudal epidural steroid injection (CESI) to all patients in both groups. Low volume group received 5 ml and highvolume group received 15 ml diluted triamcinolone solution. They were evaluated with the visual analog scale, Oswestry low back disability questionnaire, short form 12, relief of claudication and neurological disability. Results: There was no statistically significant difference in the clinical improvement between the two groups. However, there are definite distinct advantages of low volume injection such as lesser pain at injection site and no complications that warrant admission. Conclusions: The low volume technique of CESI is superior to the traditional high-volume technique in this study. Despite earlier concepts that low volume injections failed to penetrate the proximal epidural spaces, present study conclusively proved that it is superior to high volume injections.
Sportausübung 2 Jahre nach Rekonstruktion des vorderen Kreuzbands bei Sportlern, die 1 Jahr lang nicht zum Sport zurückgekehrt waren: Prospektives Follow-up der Körperfunktion und psychologische Faktoren bei 122 Sportlern

Physiotherapeutischer Hintergrund Die VKB-Ruptur gehört zu den häufigsten Sportverletzungen und hat trotz Operation und intensiver Nachbehandlung oft eine schlechte Prognose bezüglich Wiedererlangen des ursprünglichen Sportniveaus und späteren Langzeitfolgen. Inzwischen wurden viele Scores und Empfehlungen veröffentlicht, die zumeist eine Rückkehr zum Sport nach 6–12 Monaten befürworten [2]. Insbesondere unter den Amateursportlern erreicht jedoch nach einer Verletzung lediglich 1 Drittel innerhalb 1 Jahres wieder das ursprüngliche Niveau [1].
Surface Pressure a More Skillful Predictor of Normalized Hurricane Damage than Maximum Sustained Wind

Atlantic hurricane seasons have a long history of causing significant financial impacts, with Harvey, Irma, Maria, Florence, and Michael combining to incur more than 345 billion USD in direct economic damage during 2017–2018. While Michael’s damage was primarily wind and storm surge-driven, Florence’s and Harvey’s damage was predominantly rainfall and inland flood-driven. Several revised scales have been proposed to replace the Saffir–Simpson Hurricane Wind Scale (SSHWS), which currently only categorizes the hurricane wind threat, while not explicitly handling the totality of storm impacts including storm surge and rainfall. However, most of these newly-proposed scales are not easily calculated in real-time, nor can they be reliably calculated historically. In particular, they depend on storm wind radii, which remain very uncertain. Herein, we analyze the relationship between normalized historical damage caused by continental United States (CONUS) landfalling hurricanes from 1900–2018 with both maximum sustained wind speed (Vmax) and minimum sea level pressure (MSLP). We show that MSLP is a more skillful predictor of normalized damage than Vmax, with a significantly higher rank correlation between normalized damage and MSLP (rrank = 0.77) than between normalized damage and Vmax (rrank = 0.66) for all CONUS landfalling hurricanes. MSLP has served as a much better predictor of hurricane damage in recent years than Vmax, with large hurricanes such as Ike (2008) and Sandy (2012) causing much more damage than anticipated from their SSHWS ranking. MSLP is also a more accurately-measured quantity than is Vmax, making it an ideal quantity for evaluating a hurricane’s potential damage.
Rotational snapping: Illusory rhythmicity induced by global and local motion binding

The complexity of human perceptual system has often been investigated through its atypical function; the illusion. Here, I introduce a new visual illusion induced by rotational motion binding, which leads to a gestalt perception of illusory object rhythmically popping out and fading away. In this illusion, observers reported non-existing rhythm out of rotating Gabor patches (e.g., local rotation) that also have orbital trajectory with opposite direction (e.g., global rotation), only under the particular combinations of parameters. This illusory rhythmicity was four times faster than the average of global/local rotational speed. Image reconstruction using the response-triggered average revealed the rhythmicity is explained by the circular alignment of array, demonstrating the effect of repeated contour integration and its perceptual consequences.
Endothelial barrier dysfunction, loss of microcirculatory flow and organ failure in sepsis: current clinical view of sepsis and links to basic research

Sepsis and septic shock are major healthcare problems, affecting millions of people around the world each year, with an increasing incidence. In the last decades clinical and basic research have significantly improved the understanding of the complex pathophysiology of sepsis. This led to the new sepsis definition (“Sepsis-3”) which abandoned the view that sepsis is predominately defined the various immunological responses. Rather, sepsis is now defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. This view with a focus on the establishment of organ failure warrants the intensified research for therapeutic attempts to prevent and treat organ failure in sepsis. In this context, it is increasingly recognized that microvascular endothelial barrier dysfunction followed by loss of microcirculatory flow are key events leading to organ failure that should be therapeutically targeted. This review summarizes the current clinical view of the novel sepsis definition and connects it to basic research aspects of endothelial barrier regulation and loss of microcirculatory flow and thus organ protection.
Phenolphthalein Method as a Simple and Low Cost Test for Detection of Fecal Occult Blood

Background: Colorectal cancer is one of the main causes of cancer related death worldwide. Different investigation showed that screening with fecal occult blood is able to reduce incidence of colorectal cancer in a given area. To provide a simple and cost effective test for screening of colorectal cancer in this work sensitivity of phenolphthalein method in detection of occult blood has been investigated. Methods: In this descriptive study alcohol pyramidon and phenolphthalein methods were used to estimate the minimum amount of human occult blood which can be detected in distilled water and fecal samples. Then 100 fecal samples were examined by the two tests. Results: Alcohol pyramidon method detected minimum amount of 0.125 µL blood in 1 ml distilled water while phenolphthalein methods detected minimum amount of 0.0312 µL blood in 1 mL distilled water. In another experiment Alcohol pyramidon method detected minimum amount of 1 µL blood in 1 mL fecal sample while phenolphthalein methods detected minimum amount of 0.25 µL blood in about 1 mL fecal sample. Phenolphthalein method provided more positive results when 100 fecal samples were tested. Conclusion: phenolphthalein method is a sensitive, simple and economy test for colorectal cancer screening which can be used both in labs and at home.
