Strategies for Piloting a Breast Health Promotion Program in the Chinese-Australian Population

In Australia, women from non–English-speaking backgrounds participate less frequently in breast cancer screening than English-speaking women, and Chinese immigrant women are 50% less likely to participate in breast examinations than Australian-born women. Chinese-born Australians comprise 10% of the overseas-born Australian population, and the immigrant Chinese population in Australia is rapidly increasing. We report on the strategies used in a pilot breast health promotion program, Living with Healthy Breasts, aimed at Cantonese-speaking adult immigrant women in Sydney, Australia. The program consisted of a 1-day education session and a 2-hour follow-up session. We used 5 types of strategies commonly used for cultural targeting (peripheral, evidential, sociocultural, linguistic, and constituent-involving) in a framework of traditional Chinese philosophies (Confucianism, Taoism, and Buddhism) to deliver breast health messages to Chinese-Australian immigrant women. Creating the program's content and materials required careful consideration of color (pink to indicate femininity and love), symbols (peach blossoms to imply longevity), word choice (avoidance of the word death), location and timing (held in a Chinese restaurant a few months after the Chinese New Year), communication patterns (the use of metaphors and cartoons for discussing health-related matters), and concern for modesty (emphasizing that all presenters and team members were female) to maximize cultural relevance. Using these strategies may be beneficial for designing and implementing breast cancer prevention programs in Cantonese-speaking Chinese immigrant communities

Pink verrucous plaque in a man with systemic mastocytosis

Porokeratosis ptychotropica is a rare and commonly misdiagnosed subtype of porokeratosis involving the body folds. We present a 53-year-old man with systemic mastocytosis who presented with a pruritic, verrucous plaque in the gluteal fold that showed multiple cornoid lamellae on histopathologic evaluation, diagnostic of porokeratosis ptychotropica. Various treatments have been reported, including topical corticosteroids, retinoids, vitamin D analogs, calcineurin inhibitors, imiquimod, phototherapy, cryotherapy, or ablative laser therapy, but recurrences are common

Transmission Dynamics of COVID-19 in Ghana and the Impact of Public Health Interventions

This study characterized COVID-19 transmission in Ghana in 2020 and 2021 by estimating the time-varying reproduction number (Rt) and exploring its association with various public health interventions at the national and regional levels. Ghana experienced four pandemic waves, with epidemic peaks in July 2020 and January, August, and December 2021. The epidemic peak was the highest nationwide in December 2021 with Rt ≥ 2. Throughout 2020 and 2021, per-capita cumulative case count by region increased with population size. Mobility data suggested a negative correlation between Rt and staying home during the first 90 days of the pandemic. The relaxation of movement restrictions and religious gatherings was not associated with increased Rt in the regions with fewer case burdens. Rt decreased from \u3e 1 when schools reopened in January 2021 to \u3c 1 after vaccination rollout in March 2021. Findings indicated most public health interventions were associated with Rt reduction at the national and regional levels

The Use of Penalized Regression Analysis to Identify County-Level Demographic and Socioeconomic Variables Predictive of Increased COVID-19 Cumulative Case Rates in the State of Georgia

Systemic inequity concerning the social determinants of health has been known to affect morbidity and mortality for decades. Significant attention has focused on the individual-level demographic and co-morbid factors associated with rates and mortality of COVID-19. However, less attention has been given to the county-level social determinants of health that are the main drivers of health inequities. To identify the degree to which social determinants of health predict COVID-19 cumulative case rates at the county-level in Georgia, we performed a sequential, cross-sectional ecologic analysis using a diverse set of socioeconomic and demographic variables. Lasso regression was used to identify variables from collinear groups. Twelve variables correlated to cumulative case rates (for cases reported by 1 August 2020) with an adjusted r squared of 0.4525. As time progressed in the pandemic, correlation of demographic and socioeconomic factors to cumulative case rates increased, as did number of variables selected. Findings indicate the social determinants of health and demographic factors continue to predict case rates of COVID-19 at the county-level as the pandemic evolves. This research contributes to the growing body of evidence that health disparities continue to widen, disproportionality affecting vulnerable populations

Personality disorders in Asians: Summary, and a call for cultural research

Epidemiological studies show relatively low rates of personality disorder (PD) in Asian-origin samples, but these low rates may result from a lack of understanding about what constitutes PD in Asian cultural contexts. Research on etiology, assessment, and treatment has rarely been extended to incorporate ways in which culture might shape PDs in general, let alone among Asians in particular. PDs did not officially change in DSM-5, but an alternative dimensional system may help link the Asian PD literature to non-clinical personality research. Personality and culture are deeply intertwined, and the research literature on Asian PDs - and on PDs more generally - would benefit greatly from more research unpacking the cultural mechanisms of variation

A unique “turn-on” fluorescence signalling strategy for highly specific detection of ascorbic acid using carbon dots as sensing probe

Carbon dots (CDs) that showed strong blue fluorescence were successfully synthesised from sodium alginate via furnace pyrolysis. The single step pyrolytic synthesis was simple to perform while yielded CDs with high photostability, good water solubility and minimum by-products. In order to design the probe with “turn-on” sensing capability, the CDs were screened against a series of metal cations to first “turn-off” the fluorescence. It was found that ferric ions (Fe3þ) were most responsive and effective in quenching the fluorescence of CDs. Based on this observation, the conditioning of the probe was performed to ensure the fluorescence was completely quenched, while not overloading the system with Fe3þ. At the optimised condition, the CDs-Fe3þ mixture served as a highly specific detection probe for ascorbic acid (AA). The analytical potential of the probe was evaluated and showed a good linear range of response for AA concentration of 24–40 μg/mL. The selectivity study against other possible co-existing species was carried out and proved that our unique “turn-on” fluorescence signalling strategy was highly effective and selective towards AA as the target analyte. The probe was demonstrated for quantification of AA in real samples, which was the commercially available vitamin C supplement. The result showed good accuracy with minimum deviation from standard method adopted for validation purpose

Facile synthesis of carbon nanoparticles from sodium alginate via ultrasonic-assisted nano-precipitation and thermal acid dehydration for ferric ion sensing

Carbon nanoparticles have emerged as a promising alternative to the well-known quantum dots in many biological applications due to their excellent optical properties and biocompatibility. It has received considerable attentions from researchers especially in the aspects of producing these carbon nanomaterials via easier and cheaper synthetic routes. On this motivation, we hereby report an economical and facile synthesis of carbon nanoparticles from alginate via a simple two-step procedure; nano-precipitation through ultrasonication followed by thermal acid carbonisation. Nano-precipitation was first performed on the alginate stock solution to produce nanoparticles with controlled morphology. Precipitation was performed in acidic solution that has coagulated the alginate chains into nanoparticles. Ultrasonic treatment was found crucial to assist the formation of nanoparticles that were more homogenous in the size distribution at around 100 nm. The shape was also more spherical as compared to those without ultrasonic treatment. In the carbonisation step, thermal dehydration was employed using concentrated sulphuric acid that has successfully converted the preformed alginate nanoparticles into carbon nanoparticles. The carbon nanoparticles isolated showed high fluorescence even without further surface passivation. The fluorescence of these carbon nanoparticles were utilised for sensitive and selective sensing of ferric ions and it was evaluated to have a linear analytical dynamic range up to 25 μM with a limit of detection (LOD) as low as 1.06 μM. The system was successfully employed to detect ferric ions in real water sample

Double Red Blood Cell Donation Eligibility and Interest

Introduction: The process of double RBC donation by apheresis (DRBC), which facilitates the donation of two units of red blood cells (RBC) in a single donation session, was estimated to account for approximately 4% of blood donations in 2005, and is believed to be growing at a rate of 40% per year. Blood shortages in this country could be corrected by converting as few as 10% of current single unit whole blood donors to DRBC donors. Advantages of DRBC donation may include reduction in donor-related exposures in recipients, improved cost-effectiveness of the donation process, and improved convenience for donors. The safety profile of DRBC has been found to be equal to, and in some cases better than that of single unit whole blood donation, especially in young donors (/o). DRBC donors have been shown to restore 92% of RBC volume in 4 weeks without iron supplementation, and to have no significant differences in hemoglobin, serum iron, or ferritin when compared with single unit whole blood donors six months after donation. Our study seeks to quantify the number of current single unit whole blood donors who are both eligible for and interested in DRBC donation.https://scholarworks.uvm.edu/comphp_gallery/1031/thumbnail.jp

Variations and Hybridization Compatibility of Single Basidiospore Isolates of Pleurotus sajor-caju (Fr.) Sings

Pleurotus sajor-caju (Fr.) Sings, a mushroom of the family Pleurotaceae, is gaining popularity due to its high nutrient content and capability of growing on various agricultural wastes. There is a need to breed new strain of P. sajor-caju to meet the rising demands of the increasing human population. Strain improvement is achievable through selection and hybridization. Unfortunately, there is limited information regarding the genetic variations of P. sajor caju in Malaysia. Therefore, this study is of interest to document the morphological variations of single basidiospore isolates and to generate hybrids. A total of 200 single basidiospore isolates (SB) obtained from a commercialized strain of P. sajor-caju were obtained from local supermarket in Kuching, Sarawak, and cultured individually on potato dextrose agar. These 200 SBs were characterized morphologically and divided into three main groups based on colony morphology i.e. scattered, rough and smooth. Variations can still be observed in each main group. From each main group, SBs representing the variations were further categorized based on their colony diameter growth after 7 days of post inoculation (CD-7dpi), i.e. slow growing CD-7dpi (SGCD-7), medium fast growing CD-7dpi (MFGCD-7) and fast growing CD-7dpi (FGCD-7). Ten FGCD-7 and ten SGCD-7 isolates were selected for hybridization. The selected SBs were hybridized in all possible pairings without repetition. Sixteen hybridized isolates were recognized and characterized based on CD-7dpi. For all FGCD-7 pairings, SGCD-7 pairings, and between FGCD-7 and SGCD-7 pairings, hybridized isolates had higher CD-7dpi than at least one of its parents were identified. The new hybridized isolates are interesting materials for future study
