Bioabsorbable Versus Stainless Steel Screw Fixation of the Syndesmosis in Pronation-Lateral Rotation Ankle Fractures: A Prospective Randomized Trial

Thirty-two patients who had pronation-lateral rotation (PLR) fractures occurring four centimeters or more proximal to the ankle joint or lower if the talus was displaced greater than one centimeter laterally were enrolled in this study. Seventeen patients were randomized to fibular plate fixation with a 4.5 ml polylactic acid (PLA) bioabsorbable syndesmotic screw, and fifteen patients randomized to fibular plate fixation with a 4.5 mm stainless steel syndesmotic screw. All thirty-two patients had uncomplicated healing of their fibular fracture without loss of reduction. There was neither evidence of osteolysis nor sterile effusion in the patients who were treated with the PLA screw. There were no wound complications in either group. No difference in range of motion or subjective complaints was noted in either group. Use of the PLA syndesmotic screw at short-term follow-up was well tolerated and avoided the need for subsequent screw removal.
Prevalence and predictors of metabolic syndrome in women with polycystic ovarian syndrome: a study from Southern India

Background: Metabolic syndrome (MBS) is a common disorder and is thought to be highly prevalent in polycystic ovarian syndrome (PCOS). The objectives were to find out the prevalence and predictors of metabolic syndrome in women with PCOS. Methods: Forty five women diagnosed with PCOS, underwent clinical and laboratory assessments for the diagnosis of metabolic syndrome, as per modified National Cholesterol Education Program’s Adult Treatment Panel III (NCEP ATP III criteria). Results: Twenty four (53.3%) subjects had metabolic syndrome. The prevalence of individual components of the metabolic syndrome among PCOS patients were: waist circumference ≥80 cm in 36 (86.6%), High Density Lipoprotein (HDL-C) less than 50 mg/dl in 42 (93.3%), triglycerides ≥150 mg/dl in 17 (37.8%), blood pressure ≥130/85 mmHg in 7 (15.6%), and fasting plasma glucose ≥100 mg/dl in 13 (28.8%). Subjects with MBS had significantly higher BMI compared to those without (P = 0.039). However, fasting insulin and free testosterone levels did not differ significantly between subjects with and without MBS. Conclusions: The metabolic syndrome and its individual components, waist circumference ≥80 cm in particular were found to be common among PCOS patients in this study. This along with high BMI being significantly associated with MBS suggests immediate need of interventions like lifestyle changes for prevention of MBS and other cardiovascular diseases. Also, as dyslipidemia was more common than impaired fasting glucose among PCOS patients, finding of one risk factor should prompt the clinician to search for other risk factors.
Do Ultraluminous X-Ray Sources Exist in Dwarf Galaxies?

A thorough search for ultraluminous X-ray source candidates within the Local Volume is made. The search spatially matches potential ULXs detected in X-ray images or cataloged in the literature with galaxies tabulated in the Catalog of Neighboring Galaxies compiled by Karachentsev et al. The specific ULX frequency (occurrence rate per unit galaxy mass) is found to be a decreasing function of host galaxy mass for host masses above ~108.5 M☉. There is too little mass in galaxies below this point to determine whether this trend continues to lower galaxy mass. No ULXs have yet been detected in lower mass galaxies. Systematic differences between dwarf and giant galaxies that may explain an abundance of ULXs in dwarf galaxies and what they may imply about the nature of ULXs are discussed.
La identidad social y el locus de control interno en habitantes pobres del sur de Nuevo León, México

Resumen Se investigaron, mediante un modelo de ecuaciones estructurales, los efectos de la identidad social, la edad y los ingresos sobre el locus de control interno en habitantes del sur de Nuevo León, México. Como los ingresos no tuvieron ningún efecto estadísticamente significativo (β =.089, p>.05), se re-especificó el modelo, dejando sólo la identidad social y la edad. Estas sí tuvieron efectos estadísticamente significativos (β=.79, p <.05 y (β= -.19, p <.05, respectivamente), alcanzando a explicar un 60,00% de la varianza del locus de control interno gracias al modelo bifactorial. Se interpretaron los resultados en términos de la carencia de poder, para entender la relación negativa de la edad sobre el locus de control interno, y se acudió a las características de permeabilidad e impermeabilidad de la teoría de la identidad social para interpretar el efecto positivo de la identidad social de un grupo de bajo estatus sobre el locus de control interno, variable entendida en muchas ocasiones como característica de personalidad. De los índices de bondad de ajuste, el modelo sólo cumplió con el criterio de la RMSEA (p <.05), el cual es uno de los indicadores específicos más efectivos.

The group was successful in enhancing clients' self-expression and social interaction. The article describes the benefits of the art therapy-Gestalt therapy group as part of a comprehensive supportive treatment program.
A Union of Insufficiencies: Strategies for Teacher Assessment in a Period of Educational Reform.

T wo years ago, my colleagues at Stanford and I were invited to initiate a program of research in the assessment of teachers. The Na tional Board for Professional Teaching Standards was more than a year away from formation (Shulman and Sykes 1986). But a new generation of ways to assess the capacities required for teaching was needed. There was wide spread dissatisfaction with the quality and character of existing test-, and observation instruments for evaluating teachers. Given the nature of the existing approaches, which com prised primarily multiple-choice tests and generic observation scales, the challenge was to find a starting point for our effort. Our work on a new set of ap proaches to teacher assessment did not emerge from an interest in mea surement or testing per se. For over three years, with the support of a grant from the Spencer Foundation, my col leagues and I had already been con ducting in-depth longitudinal studies of how new high school teachers learn to teach. More specifically, in the con-
Texture Fuzzy Segmentation using Skew Divergence Adaptive Affinity Functions

Digital image segmentation is the process of assigning distinct labels to different objects in a digital image, and the fuzzy segmentation algorithm has been successfully used in the segmentation of images from a wide variety of sources. However, the traditional fuzzy segmentation algorithm fails to segment objects that are characterized by textures whose patterns cannot be successfully described by simple statistics computed over a very restricted area. In this paper, we propose an extension of the fuzzy segmentation algorithm that uses adaptive textural affinity functions to perform the segmentation of such objects on bidimensional images. The adaptive affinity functions compute their appropriate neighborhood size as they compute the texture descriptors surrounding the seed spels (spatial elements), according to the characteristics of the texture being processed. The algorithm then segments the image with an appropriate neighborhood for each object. We performed experiments on mosaic images that were composed using images from the Brodatz database, and compared our results with the ones produced by a recently published texture segmentation algorithm, showing the applicability of our method.
Too complicated for the field? Measuring quality of care in humanitarian aid settings

While quality of care is a major concern in the western world, not many studies investigate this topic in low-income countries. Even less is known about the quality of care in humanitarian aid settings, where additional challenges from natural or manmade disasters contribute to additional challenges. This study tried to address this gap by introducing a new approach to systematically measure quality of care in a project of Médecins Sans Frontières (MSF) in Agok area, between South Sudan and Sudan. Our objective was to obtain a valid snapshot of quality of care for a MSF project in three weeks that has the potential to serve as a baseline for quality improvement strategies. The evaluation followed a cross-sectional study design to assess structural, process and outcome quality according to Donabedian's criteria of quality of care. A bundle of well-established methods for collection of quantitative and qualitative data was used to assess the project by following a triangulated mixed-methods approach. Mean structural quality scored 73% of expected performance level and mean process quality 59%. The overall mortality rate for the hospital was 3.6%. On average, less complicated cases got a better level of care than patients who were seriously ill. Significant motivational issues were discovered in staff interviews potentially affecting quality of care. The tool appeared to be quick, feasible and effective in judging quality of care in the selected project. To tap the whole potential of the approach a re-evaluation should be carried out to assess the effectiveness of implemented improvement strategies in Agok. To confirm the usefulness of the approach, more studies are needed covering the variety of different humanitarian aid settings.
Social Information Processing and the Effects of Reputational, Situational, Developmental, and Gender Factors among Children's Sociometric Groups.

Second and fifth graders (n = 120) from five sociometric status groups were individu ally interviewed for their attributional, emotional, and behavioral responses to hypo thetical social encounters with same-sex and same-grade known peers who also rep resented five sociometric statuses. Rejected children usually elicited more negative feelings, and second graders generally responded more negatively than did fifth grad ers, to nonambiguous situations when a known peer behaved appropriately. Gender differences were found in children's social information processing. Popular and ne glected girls had more negative attributions and emotions than did their male so ciometric counterparts. Neglected girls appear to be at high risk for deficient process ing of social information. Implications for social skills training are discussed.

A Proposed Intelligent Denoising Technique for Spatial Video Denoising for Real-Time Applications

With the widespread use of videos in many fields of our lives, it becomes very important to develop new techniques for video denoising. Spatial video denoising using wavelet transform has been the focus of the current research, as it requires less computation and more suitable for real-time applications. Two specific techniques for spatial video denoising using wavelet transform are considered in this work: 2D Discrete Wavelet Transform 2D DWT and 2D Dual Tree Complex Wavelet Transform 2D DTCWT. We performed an analytical analysis to investigate the performance of each of these techniques. From this analysis, we found out that each of these techniques has its advantages and disadvantages. The first technique gives less quality at high levels of noise but consumes less time, whereas the second gives high quality video while consuming a large amount of time. In this work, we introduce an intelligent denoising system that makes a tradeoff between the quality of the denoised video and the time required for denoising. The system first estimates the noise level in the video frame then chooses the proper denoising technique to apply on the frame. The simulation results show that the proposed system is more suitable for real-time applications where time is critical, while still giving high quality videos at low to moderate levels of noise.
Modes of Caldesmon Binding to Actin

Smooth muscle caldesmon binds actin and inhibits actomyosin ATPase activity. Phosphorylation of caldesmon by extracellular signal-regulated kinase (ERK) reverses this inhibitory effect and weakens actin binding. To better understand this function, we have examined the phosphorylation-dependent contact sites of caldesmon on actin by low dose electron microscopy and three-dimensional reconstruction of actin filaments decorated with a C-terminal fragment, hH32K, of human caldesmon containing the principal actin-binding domains. Helical reconstruction of negatively stained filaments demonstrated that hH32K is located on the inner portion of actin subdomain 1, traversing its upper surface toward the C-terminal segment of actin, and forms a bridge to the neighboring actin monomer of the adjacent long pitch helical strand by connecting to its subdomain 3. Such lateral binding was supported by cross-linking experiments using a mutant isoform, which was capable of cross-linking actin subunits. Upon ERK phosphorylation, however, the mutant no longer cross-linked actin to polymers. Three-dimensional reconstruction of ERK-phosphorylated hH32K indeed indicated loss of the interstrand connectivity. These results, together with fluorescence quenching data, are consistent with a phosphorylation-dependent conformational change that moves the C-terminal end segment of caldesmon near the phosphorylation site but not the upstream region around Cys595, away from F-actin, thus neutralizing its inhibitory effect on actomyosin interactions. The binding pattern of hH32K suggests a mechanism by which unphosphorylated, but not ERK-phosphorylated, caldesmon could stabilize actin filaments and resist F-actin severing or depolymerization in both smooth muscle and nonmuscle cells.
Are Dysregulated Inflammatory Responses to Commensal Bacteria Involved in the Pathogenesis of Hepatobiliary-Pancreatic Autoimmune Disease? An Analysis Using Mice Models of Primary Biliary Cirrhosis and Autoimmune Pancreatitis

The etiopathogenesis of many autoimmune disorders has not been identified. The aim of this paper is to focus on the involvement of bacterial exposure in the pathogenesis of primary biliary cirrhosis (PBC) and autoimmune pancreatitis (AIP), both of which are broadly categorized as autoimmune disorders involving hepatobiliary-pancreatic lesions. Avirulent and/or commensal bacteria, which may have important role(s) as initiating factors in the pathogenesis of autoimmune disorders such as PBC and AIP, will be emphasized.
Charge-Transfer Interactions in Organic Functional Materials

Our goal in this review is three-fold. First, we provide an overview of a number of quantum-chemical methods that can abstract charge-transfer (CT) information on the excited-state species of organic conjugated materials, which can then be exploited for the understanding and design of organic photodiodes and solar cells at the molecular level. We stress that the Composite-Molecule (CM) model is useful for evaluating the electronic excited states and excitonic couplings of the organic molecules in the solid state. We start from a simple polyene dimer as an example to illustrate how interchain separation and chain size affect the intercahin interaction and the role of the charge transfer interaction in the excited state of the polyene dimers. With the basic knowledge from analysis of the polyene system, we then study more practical organic materials such as oligophenylenevinylenes (OPVn), oligothiophenes (OTn), and oligophenylenes (OPn). Finally, we apply this method to address the delocalization pathway (through-bond and/or through-space) in the lowest excited state for cyclophanes by combining the charge-transfer contributions calculated on the cyclophanes and the corresponding hypothetical molecules with tethers removed. This review represents a step forward in the understanding of the nature of the charge-transfer interactions in the excited state of organic functional materials.
Antibiotic stewardship: Why we must, how we can

Improving our antibiotic use is critical to the safety of our patients and the future of medicine. This can improve patient outcomes, save money, reduce resistance, and help prevent negative consequences such as Clostridium difficile infection. The US Centers for Disease Control and Prevention (CDC) is undertaking a nationwide effort to appropriately improve antibiotic use in inpatient and outpatient settings. It has always been a good idea; now it is required.
Gender Differences in the Use of Intensifiers in Persian

Men and women use different linguistic forms though they might come from the same homogeneous speech community. This study is an attempt to investigate the differential usage of intensifiers in male and female speech in Persian. About four hours of naturally-occurring spontaneous conversations between male and female participants were recorded, transcribed and examined for the use of intensifiers. Frequency counts and the Chi-square test were used to analyze the data. The results indicated that women used intensifiers significantly more than men. The findings were seen to support the previous findings in this regard. They also furthered our understanding of gendered speech in Persian.
A Brillouin scattering study of the hydration of Li‐ and Na‐DNA films

We have used Brillouin spectroscopy to study the velocities and attenuation of acoustic phonons in wet‐spun films of Na‐DNA and Li‐DNA as a function of the degree of hydration at room temperature. Our data for the longitudinal acoustic (LA) phonon velocity vs water content display several interesting features and reveal effects that we can model at the atomic level as interhelical bond softening and relaxation of the hydration shell. The model for interhelical softening makes use of other physical parameters of these films, which we have determined by gravimetric, x‐ray, and optical microscopy studies. We extract intrinsic elastic constants for hydrated Na‐DNA molecules of c11 ≃ 8.0 × 1010 dynes/cm2 and c33 ≃ 5.7 × 1010 dynes/cm2, which corresponds to a Young's modulus, E ≃ 1.1 × 1010 dynes/cm2 (with Poisson's ratio, σ = 0.44). The negative velocity anisotropy of the LA phonons indicates that neighboring DNA molecules are held together by strong interhelical bonds in the solid state. The LA phonon attenuation data can be understood by the relaxational model in which the acoustic phonon is coupled to a relaxation mode of the water molecules. Na‐DNA undergoes the A to B phase transition at a relative humidity (rh) of 92% while Li‐DNA (which remains in the B form in this range) decrystallizes at an rh of 84%. We find that our Brillouin results for Na‐ and Li‐DNA are remarkably similar, indicating that the A to B phase transition does not play an important role in determining the acoustic properties of these two types of DNA.
A cloud-assisted DASH-based Scalable Interactive Multiview Video Streaming framework

Interactive multiview video streaming (IMVS) allows viewers to periodically switch viewpoint. Its user experience can be further enhanced by creating virtual views from neighboring coded views using view synthesis techniques. Dynamic adaptive streaming over HTTP (DASH) is a new standard that can adjust the quality of video streaming according to the network condition. In this paper, we propose an improved DASH-based IMVS scheme over wireless networks. The main contributions are twofold. First, our scheme allows virtual views to be generated at either the cloud-based server or the client, and can adaptively select the optimal approach based on the network condition and the cost of the cloud. Second, scalable video coding is used in our system. Simulations with the NS3 tool demonstrate the advantage of our proposed scheme over the existing approach with client-based view synthesis and single-layer video coding.
