Brain & guitar neck melanoma: A new 22-year experience with recurrence pursuing sentinel lymph node biopsy.
Indigenous peoples in Canada and other settler colonial nations experience barriers to healing in the health care system and their communities. Drawing on four sequential sharing circles and indepth interviews with 11 Indigenous men, this article shares the stories of Indigenous men and their healing journeys with the aim of improving culturally safe support in the community. In sharing their stories, these men identified coping with colonialism, as well as trauma and grief, as barriers in their healing journey. They also described finding strength in cultural role models, fathering, as well as ceremony and connecting to the land. We discuss the implications of these findings for service provision and decolonizing community health services.Within Miami-Dade County, Black women experience disproportionate rates of HIV incidence and prevalence. Status disclosure to sexual partners is central to mitigating the HIV epidemic and ensuring a healthier lifestyle for those living with the virus. The disclosure processes model (DPM) posits that barriers such as stigma and negative outcome expectations often facilitate disclosure avoidance. Therefore, this study investigated the utility and acceptability of an entertainment-education (EE) short film, 90 DAYS, for disclosure among Black women living with HIV in Miami-Dade County. Employing photo-elicitation (Harper, 2002), focus groups were conducted with 48 participants. After screening the 90 DAYS film about stigma and disclosure, participants were asked semi-structured questions based upon extant EE and DPM literature. Via inductive and deductive processes, five themes were derived from the data. Participants found the 90 DAYS film to be an empowering counter-narrative that could be used to overcome multiple disclosure-related factors. They felt it provided a social script for how to disclose to their sexual partners. A novel finding of this investigation was that respondents asserted the film could facilitate safer disclosure events. Additional themes included the film being a resource of hope for young and newly diagnosed women; and an educational tool for the community. Altogether, findings lend promise to the use of EE for addressing disclosure avoidance among Black women living with HIV.The letter is devoted to a method for determining electric equivalent circuit parameters of piezoelectric ceramic transducers from their resonance characteristics. These parameters represent equivalents of mechanical damping, effective weight of the oscillating element, compliance of the mechanical element and static capacitance associated with the transducer material. This method is considered cost efficient, focuses on transducers commonly available on the market and is presented on a specific transducer - transmitter. The acquired parameters are important for performing subsequent simulations and defining their suitability for a particular application. However, these parameters are not included in the usual technical documentation of the commercially available piezoelectric ceramic transducers. The key part of this letter is an iterative process of finding the parameters. Before starting the iteration process, it is very important to set default values of these parameters. Then, a linearized system of equations, based on expressing a real part of the impedance, is used to determine these parameters. The advantage of this method is its simplicity to measure only the two above-mentioned characteristics, from which the required parameters can be then calculated. Thus, there is no need for expensive circuit analyzers, which are able to determine these parameters directly. Although the iterative process includes a large number of steps, and therefore can be relatively time consuming, it can be performed on a commercially available computer technology.Baseband Delay-Multiply-and-Sum (BB-DMAS) beamforming takes advantage of the baseband spatial coherence of receiving aperture to improve image resolution and contrast. Meanwhile, the side-lobe clutter and noise level can also be effectively suppressed in BB-DMAS beamforming due to their low coherence when being detected by channels in different spatial locations. BB-DMAS scales the magnitude of channel signal by p-th root and restores the output dimensionality by p-th power after channel summation. Higher p value introduces more spatial coherence into DMAS beamforming and provides higher image resolution at the cost of background speckle quality. Cerivastatin sodium mouse In this study, a computationally efficient integration of BB-DMAS with minimum-variance (MV) beamforming is developed so that the image resolution can be drastically improved with low p value (e.g. p less then 2) while maintaining the speckle quality. For each image pixel, the proposed MV-DMAS only requires single MV estimation to optimize the aperture apodization for DMAS beamforming. Our simulation results show that, with p = 1.5, the -6-dB lateral width of wire reflector noticeably improves from 0.22 mm to 0.13 mm by adopting MV estimation in BB-DMAS beamforming. In MV-DMAS, the suppression of uncorrelated random noises also remains effective. Experimental results not only confirm the superior resolution in MV-DMAS beamforming but also demonstrates comparable image contrast and speckle quality to BB-DMAS counterpart. In conclusion, MV-DMAS beamforming can provide improvement in image resolution while maintaining the other image quality metrics using an efficient combination of moderate spatial coherence and MV estimation of receiving aperture apodization in ultrasonic imaging.The aim of this study was to investigate the clinical risk factors, phenomenology and the impact of clozapine induced obsessive-compulsive symptoms (OCS) in patients with schizophrenia. One hundred twenty-two patients receiving clozapine treatment for at least 6 weeks were assessed with Structured Clinical Interview for Axis-I Disorders for DSM-IV, Positive and Negative Syndrome Scale, Yale-Brown Obsessive Compulsive Scale and Checklist, Calgary Depression Scale, Clinical Global Impression Scale and WHO-Disability Assessment Schedule-II. Information about past and current clinical status were gathered through clinical interviews and medical records. With clozapine 44.3% of the patients had de novo OCS, 33.6% had OCS both before and after clozapine, 21.3% didn't report any OCS. Clozapine doses, clozapine and norclozapine plasma levels were not significantly different. Severity of OCS was affected by clozapine and norclozapine plasma levels, and correlated with increased disability. Obsessions were less in clozapine induced OCS group, and compulsions, especially of checking subtypes, were predominant, compared to the group with prior history of OCS, who reported a significant increase in checking compulsion after clozapine treatment.
