RESUMEN

During the response to the COVID-19 pandemic, doctors will be redeployed into roles with which they are unfamiliar. Adequate training must be provided to reacquaint doctors with medical ward practice, supporting psychological wellbeing and patient safety. Here we describe a cross-skilling programme in North Bristol NHS Trust designed to address colleague anxiety and support wellbeing during redeployment.

RESUMEN

BACKGROUND: The effectiveness of healthy food promotion on food and beverage sales in real-world food retail settings has been shown in randomised trials. The effectiveness of restrictions on the promotion of unhealthy food is, however, less clear. We aimed to assess the effect of restricted unhealthy food promotion, specifically those items contributing most to free sugar sales, on food and beverage sales. METHODS: In this community-level pragmatic, partially randomised, parallel group trial, stores were randomly assigned by a statistician using a single sequence of random assignments to the intervention group, in which a co-designed strategy restricted merchandising of unhealthy food, or to a control group of usual retail practice. The trial was done in partnership with an organisation operating 25 stores in remote Australia. The primary analysis was based on difference in weekly sales with the strategy compared with no strategy in free sugar from all foods and beverages (g/total MJ; primary outcome), targeted food or beverages (weight and free sugars; g/total MJ), and gross profit (AU$) using mixed models. This trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12618001588280. FINDINGS: Between June 13 and Aug 15, 2018, 20 stores were recruited; ten stores were randomly assigned to the intervention group and ten stores to the control group. The trial was done between Sept 2 and Dec 2, 2018. The Healthy Stores 2020 strategy resulted in a reduction in sales of free sugar of 2·8% (95% CI -4·9 to -0·7). Targeted beverages were reduced by 8·4% (-12·3 to -4·3) and associated free sugar by 6·8% (-10·9 to -2·6), sugar-sweetened soft drinks by 13·2% (-18·5 to -7·6), and associated free sugar by 13·4% (-18·7 to -7·7). Reductions in sales of free sugar from confectionery of 7·5% (-14·3 to -0·2) and in weight sold (-4·6%, -11·1 to 2·3) resulted; however, the reduction in weight was not statistically significant. No differences in sales of table sugar and sweet biscuits were observed. Gross profit was not impacted adversely; a small increase resulted (5·3%, 0·3 to 10·5). INTERPRETATION: Restricted merchandising of unhealthy foods and beverages, while allowing for complementary merchandising of healthier foods and beverages in a real-world store setting and co-designed with retailers, can achieve both public health and business relevant gains.

RESUMEN

Emergency airway management is often complicated by the presence of blood, emesis or other contaminants in the airway. Traditional airway management education has lacked task-specific training focused on mitigating massive airway contamination. The Suction Assisted Laryngoscopy and Airway Decontamination (SALAD) technique was developed in order to address the problem of massive airway contamination both in simulation training and in vivo. We review the evidence describing the dangers associated with airway contamination, and describe the SALAD technique in detail.

RESUMEN

PURPOSE: To validate whether prostate-specific antigen (PSA) level after neoadjuvant androgen suppression (neoAS) is associated with long-term outcome after neoAS and external beam radiation therapy (RT) with concurrent short-term androgen suppression (AS) in patients with prostate cancer. METHODS AND MATERIALS: This study included 2404 patients. The patients were treated with neoAS before RT and concurrent AS (without post-RT AS) and were pooled from NRG Oncology/RTOG trials 9202, 9408, 9413, and 9910. Multivariable models were used to test associations between the prespecified dichotomized post-neoAS, pre-RT PSA level (≤0.1 vs >0.1 ng/mL) groupings, and clinical outcomes. RESULTS: The median follow-up for surviving patients was 9.4 years. The median post-neoAS, pre-RT PSA level was 0.3 ng/mL, with 32% of patients having levels ≤0.1 ng/mL. Race, Gleason score, tumor stage, node stage, pretreatment PSA level, and duration of neoAS were associated with the groups of patients with PSA levels ≤0.1 and >0.1 ng/mL. In univariate analyses, post-neoAS, pre-RT PSA level >0.1 ng/mL was associated with increased risks of biochemical failure (hazard ratio [HR], 2.04; P < .0001); local failure (HR, 2.51; P < .0001); distant metastases (HR, 1.73; P = .0006); cause-specific mortality (HR, 2.36; P < .0001); and all-cause mortality (HR, 1.24; P = .005). In multivariable models that also included baseline and treatment variables, post-neoAS, pre-RT PSA level >0.1 ng/mL was independently associated with increased risk of biochemical failure (HR, 2.00; P < .0001); local failure (HR, 2.33; P < .0001); and cause-specific mortality (HR, 1.75; P = .03). CONCLUSIONS: Patients with a PSA level >0.1 ng/mL after neoAS and before the start of RT had less favorable clinical outcomes than patients whose PSA level was ≤0.1 ng/mL. The role of post-neoAS, pre-RT PSA level relative to PSA levels obtained along the continuum of medical care is not presently defined but could be tested in future clinical trials.

RESUMEN

BACKGROUND: Discretionary food and beverages (products high in saturated fat, added sugars, and salt) are detrimental to a healthy diet. Nevertheless, they provide 42% of total energy and account for 53% of food and beverage expenditure for remote living Aboriginal and Torres Strait Islander Australians, contributing to the excessive burden of chronic diseases experienced by this population group. OBJECTIVE: The aim of this study is to test an intervention to reduce sales of discretionary products, in collaboration with the Arnhem Land Progress Aboriginal Corporation (ALPA), which operates 25 stores in very remote Australia, by reducing their merchandising and substituting with core products in remote Australian communities. METHODS: We will use a community-level randomized controlled pragmatic trial design. Stores randomized to the intervention group will be supported by ALPA to reduce merchandising of 4 food categories (sugar, sugar-sweetened beverages, sweet biscuits, and confectionery) that together provide 64% of energy from discretionary foods and 87% of total free sugars in very remote community stores. The remaining stores (50% of total) will serve as controls and conduct business as usual. Electronic store sales data will be collected at baseline, 12-weeks intervention, and 24-weeks postintervention to objectively assess the primary outcome of percent change in purchases of free sugars (g/megajoule) and secondary business- and diet-related outcomes. Critical to ensuring translation to improved store policies and healthier diets in remote Indigenous Australia, we will conduct (1) an in-depth implementation evaluation to assess fidelity, (2) a customer intercept survey to investigate the relationship between customer characteristics and discretionary food purchasing, and (3) a qualitative study to identify policy supports for scale-up of health-enabling policy action in stores. RESULTS: As of August 2018, 20 stores consented to participate and were randomized to receive the intervention or continue usual business. The 12-week strategy ended in December 2018. The 24-week postintervention follow-up will occur in May 2019. Trial results are expected for 2019. CONCLUSIONS: Novel pragmatic research approaches are needed to inform policy for healthy retail food environments. This research will greatly advance our understanding of how the retail food environment can be used to improve population-level diet in the remote Australian Aboriginal and Torres Strait Islander context and retail settings globally.

RESUMEN

BACKGROUND: Evidence is mounting that price discounts can be effective in improving diet. This study examined the effectiveness of a 20% price discount on food and drink purchases with and without consumer education in remote Indigenous Australia. METHODS: A 20% discount on fruit, vegetables, water, and artificially sweetened soft drinks was applied for 24 weeks in 20 communities in remote Indigenous Australia where the community store was managed by the Arnhem Land Progress Aboriginal Corporation (ALPA) or Outback Stores (OBS) in a stepped-wedge randomised trial. Communities were randomly allocated to a fixed framework of five sets of four stratified by store association; ten stores (two in each set) were randomly assigned to receive consumer education. A store from each of the ALPA and OBS store groups (contained in separate opaque envelopes) was selected, and stores in turn continued to be consecutively allocated to the fixed store set framework, starting with the first store slot in the first store set, until all stores had been allocated. The effect of the discount on the weight of fruit and vegetables purchased (the primary endpoint) was assessed using weekly store sales data and mixed models per protocol. We did sensitivity analyses by repeating the analyses with the outliers included and repeating the analyses for the primary outcome measure removing each store one at a time. This trial was registered with Australian New Zealand Clinical Trials Registry, number ACTRN12613000694718. FINDINGS: Weekly store sales data on all food and drink products sold in 20 stores were collected from July 1, 2012, to Dec 28, 2014. Price discount alone was associated with a 12·7% (95% CI 4·1-22·1) increase in purchases in grams of fruit and vegetables combined (primary outcome), and a 19·8% (6·2-35·1) increase post discount (after vs before); an effect of 12 g and 18 g per capita per day. Sensitivity analyses did not modify the results for the primary outcome measure. INTERPRETATION: A 20% discount can only increase fruit and vegetable purchases to help protect against obesity and diet related disease to a certain extent. Large discounts might have a greater impact than small discounts. Creative merchandising approaches to consumer education could also be considered alongside fiscal interventions to achieve marked improvements in diet.

RESUMEN

Mature oak (Quercus spp.) leaves, although abundantly available during the plants' developmental cycle, are rarely exploited as viable sources of genomic DNA. These leaves are rich in metabolites difficult to remove during standard DNA purification, interfering with downstream molecular genetics applications. The current work assessed whether in situ dark adaptation, to deplete sugar reserves and inhibit secondary metabolite synthesis could compensate for the difficulties encountered when isolating DNA from mature leaves rich in secondary metabolites. We optimized a rapid, commercial kit based method to extract genomic DNA from dark- and light-adapted leaves. We demonstrated that in situ dark adaptation increases the yield and quality of genomic DNA obtained from mature oak leaves, yielding templates of sufficiently high quality for direct downstream applications, such as PCR amplification and gene identification. The quality of templates isolated from dark-adapted pin oak leaves particularly improved the amplification of larger fragments in our experiments. From DNA extracts prepared with our optimized method, we identified for the first time partial segments of the genes encoding 18S rRNA and isoprene synthase (IspS) from pin oak (Quercus palustris), whose full genome has not yet been sequenced.

RESUMEN

OBJECTIVE: To explore availability, variety and frequency consumption of traditional foods and their role in alleviating food insecurity in remote Aboriginal Australia. METHODS: Availability was assessed through repeated semi-structured interviews and consumption via a survey. Quantitative data were described and qualitative data classified. RESULTS: Aboriginal and non-Indigenous key informants (n=30 in 2013; n=19 in 2014) from 20 Northern Territory (NT) communities participated in interviews. Aboriginal primary household shoppers (n=73 in 2014) in five of these communities participated in a survey. Traditional foods were reported to be available year-round in all 20 communities. Most participants (89%) reported consuming a variety of traditional foods at least fortnightly and 71% at least weekly. Seventy-six per cent reported being food insecure, with 40% obtaining traditional food during these times. CONCLUSIONS: Traditional food is consumed frequently by Aboriginal people living in remote NT. Implications for public health: Quantifying dietary contribution of traditional food would complement estimated population dietary intake. It would contribute evidence of nutrition transition and differences in intakes across age groups and inform dietary, environmental and social interventions and policy. Designing and conducting assessment of traditional food intake in conjunction with Aboriginal leaders warrants consideration.

RESUMEN

Vulvar cancer is a rare carcinoma constituting only 4% of gynecologic malignancies and 0.6% of female cancers. Most chemotherapy regimens have been created from extrapolation from anal and cervical cancer research. Advanced stages have the worst prognosis and oftentimes invasive surgical procedures are needed to cure disease with high recurrence rates. Case. A 50 yo G2P2 presented for a 2 cm mass in her right labia. The patient underwent a partial radical vulvectomy and bilateral superficial and deep inguinal lymph node dissection. Bilateral inguinal lymph nodes were positive for residual disease. The patient underwent whole pelvic radiation with cisplatin as a radiosensitizer. The primary tumor was epidermal growth factor receptor (EGFR) positive and cetuximab, a monoclonal antibody to EGFR, was added. The patient underwent seven cycles of chemotherapy including cisplatin and cetuximab with adjuvant radiation therapy to the pelvis. She currently is without evidence of disease recurrence since completing treatment 4 years ago. Conclusion. One previous case report showed short-term palliative success of five months for recurrent, metastatic vulvar cancer. This case suggests that cetuximab could possibly be used in initial management of patients with advanced stages of vulvar cancer to improve prognosis.

RESUMEN

Salivary gland cancers are rare and represent approximately 5% of all head and neck cancers and only 0.3% of all malignancies. The majority (75%) of salivary gland tumors occur in the parotid gland, and while benign lesions are more common, mucoepidermoid carcinoma (MEC) makes up 40-50% of malignant parotid gland tumors. No randomized controlled trials exist regarding the role of adjuvant radiation for patients who undergo surgical resection of low-grade MECs. Herein, we report two cases of successful postoperative radiation therapy in low-grade, pT2N0 MEC of the parotid gland. The role of adjuvant radiation therapy for patients with MEC of the parotid gland is based on data from institution reviews and lacks data from randomized controlled trials. Per our review of the literature, the pathological findings of positive surgical margins and/or perineural invasion in two patients with low-grade MEC of the parotid gland warranted adjuvant radiation for improved local control after partial parotidectomy. Both patients tolerated postoperative radiation therapy with only mild side effects and, at last follow-up, five years after completion of therapy, had no clinical or radiographic evidence of either local recurrence or distant metastasis.

RESUMEN

BACKGROUND: Indigenous Australians suffer a disproportionate burden of preventable chronic disease compared to their non-Indigenous counterparts--much of it diet-related. Increasing fruit and vegetable intakes and reducing sugar-sweetened soft-drink consumption can reduce the risk of preventable chronic disease. There is evidence from some general population studies that subsidising healthier foods can modify dietary behaviour. There is little such evidence relating specifically to socio-economically disadvantaged populations, even though dietary behaviour in such populations is arguably more likely to be susceptible to such interventions.This study aims to assess the impact and cost-effectiveness of a price discount intervention with or without an in-store nutrition education intervention on purchases of fruit, vegetables, water and diet soft-drinks among remote Indigenous communities. METHODS/DESIGN: We will utilise a randomised multiple baseline (stepped wedge) design involving 20 communities in remote Indigenous Australia. The study will be conducted in partnership with two store associations and twenty Indigenous store boards. Communities will be randomised to either i) a 20% price discount on fruit, vegetables, water and diet soft-drinks; or ii) a combined price discount and in-store nutrition education strategy. These interventions will be initiated, at one of five possible time-points, spaced two-months apart. Weekly point-of-sale data will be collected from each community store before, during, and for six months after the six-month intervention period to measure impact on purchasing of discounted food and drinks. Data on physical, social and economic factors influencing weekly store sales will be collected in order to identify important covariates. Intervention fidelity and mediators of behaviour change will also be assessed. DISCUSSION: This study will provide original evidence on the effectiveness and cost-effectiveness of price discounts with or without an in-store nutrition education intervention on food and drink purchasing among a socio-economically disadvantaged population in a real-life setting.

RESUMEN

A case of monophasic intra-articular synovial sarcoma in the right knee of a 39-year-old active duty serviceman treated with a transfemoral amputation is presented. The patient was evaluated for right knee pain and fullness. After further workup, the patient underwent computed tomography guided biopsy, with the tissue specimen consistent with intra-articular synovial sarcoma. The patient elected for a transfemoral amputation rather than limb or joint-sparing surgery. The gross specimen measured 3.5 × 3.0 × 1.7 cm in the posteromedial knee. No metastatic lesions were seen on positron emission tomography-computed tomography. Chemotherapy and radiation therapy have not been utilized. The transfemoral amputation adds to the uniqueness of this report and is discussed with a review of the multimodality treatment toward intra-articular synovial sarcoma in prior published literature.

RESUMEN

Primary lymphoma of the breast is a rare entity in the field of oncological medicine and represents <0.5% of all breast malignancies. A definitive diagnosis is obtained by excisional biopsy as the clinical and radiographical presentation is similar to the more common primary breast carcinoma. Unlike primary breast carcinoma, localized radiation therapy is the mainstay of treatment. We report on a case of primary follicular lymphoma of the breast in a 67-year-old Caucasian woman treated with localized radiation as well as coinciding literature review regarding outcomes of different treatment modalities.

RESUMEN

Among its many functions, the ubiquitin-proteasome system regulates substrate-specific proteolysis during the cell cycle, apoptosis, and fertilization and in pathologies such as Alzheimer's disease, cancer, and liver cirrhosis. Proteasomes are present in human and boar spermatozoa, but little is known about the interactions of proteasomal subunits with other sperm proteins or structures. We have created a transgenic boar with green fluorescent protein (GFP) tagged 20S proteasomal core subunit α-type 1 (PSMA1-GFP), hypothesizing that the PSMA1-GFP fusion protein will be incorporated into functional sperm proteasomes. Using direct epifluorescence imaging and indirect immunofluorescence detection, we have confirmed the presence of PSMA1-GFP in the sperm acrosome. Western blotting revealed a protein band corresponding to the predicted mass of PSMA1-GFP fusion protein (57 kDa) in transgenic spermatozoa. Transgenic boar fertility was confirmed by in vitro fertilization, resulting in transgenic blastocysts, and by mating, resulting in healthy transgenic offspring. Immunoprecipitation and proteomic analysis revealed that PSMA1-GFP copurifies with several acrosomal membrane-associated proteins (e.g., lactadherin/milk fat globule E8 and spermadhesin alanine-tryptophan-asparagine). The interaction of MFGE8 with PSMA1-GFP was confirmed through cross-immunoprecipitation. The identified proteasome-interacting proteins may regulate sperm proteasomal activity during fertilization or may be the substrates of proteasomal proteolysis during fertilization. Proteomic analysis also confirmed the interaction/coimmunoprecipitation of PSMA1-GFP with 13/14 proteasomal core subunits. These results demonstrate that the PSMA1-GFP was incorporated in the assembled sperm proteasomes. This mammal carrying green fluorescent proteasomes will be useful for studies of fertilization and wherever the ubiquitin-proteasome system plays a role in cellular function or pathology.

RESUMEN

BACKGROUND: Very high levels of ionizing radiation exposure have been associated with the development of soft-tissue sarcoma. The effects of lower levels of ionizing radiation on sarcoma development are unknown. This study addressed the role of low to moderately high levels of ionizing radiation exposure in the development of soft-tissue sarcoma. METHODS: Based on the Life Span Study cohort of Japanese atomic-bomb survivors, 80,180 individuals were prospectively assessed for the development of primary soft-tissue sarcoma. Colon dose in gray (Gy), the excess relative risk, and the excess absolute rate per Gy absorbed ionizing radiation dose were assessed. Subject demographic, age-specific, and survival parameters were evaluated. RESULTS: One hundred and four soft-tissue sarcomas were identified (mean colon dose = 0.18 Gy), associated with a 39% five-year survival rate. Mean ages at the time of the bombings and sarcoma diagnosis were 26.8 and 63.6 years, respectively. A linear dose-response model with an excess relative risk of 1.01 per Gy (95% confidence interval [CI]: 0.13 to 2.46; p = 0.019) and an excess absolute risk per Gy of 4.3 per 100,000 persons per year (95% CI: 1.1 to 8.9; p = 0.001) were noted in the development of soft-tissue sarcoma. CONCLUSIONS: This is one of the largest and longest studies (fifty-six years from the time of exposure to the time of follow-up) to assess ionizing radiation effects on the development of soft-tissue sarcoma. This is the first study to suggest that lower levels of ionizing radiation may be associated with the development of soft-tissue sarcoma, with exposure of 1 Gy doubling the risk of soft-tissue sarcoma development (linear dose-response). The five-year survival rate of patients with soft-tissue sarcoma in this population was much lower than that reported elsewhere.

RESUMEN

Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare cutaneous neoplasm microscopically similar to undifferentiated nasopharyngeal carcinoma. It is typically nonaggressive and is treated with wide local excision. However, we present a case of a patient with a regional recurrence and more aggressive LELCS with perineural invasion and positive margins for which he was treated with wide local excision followed by chemoradiation. We discuss the use of chemoradiation for this patient and review the literature, specifically pertaining to treatment of more aggressive cases of LELCS.

RESUMEN

The use of staging imaging modalities with increased sensitivity has led to an increase in the incidence of detection of simultaneous malignancies. These cases require careful evaluation and discussion in a multidisciplinary setting to establish a treatment plan that optimizes the outcome with respect to each malignancy, particularly when treatment modalities overlap. We report a case of a patient diagnosed with axillary nodal diffuse large B-cell lymphoma (DLBCL) in a community hospital where staging workup also revealed synchronous bilateral breast carcinomas. To our knowledge, this is only the second case report of a patient with three synchronous primary malignancies: bilateral breast carcinomas and axillary DLBCL. The only other similar case report had no role for radiation or chemotherapy in the management of the indolent follicular lymphoma.

RESUMEN

As a tropical archipelagic nation, the Philippines is particularly susceptible to coastal hazards, which are likely to be exacerbated by climate change. To improve coastal hazard management and adaptation planning, it is imperative that climate information be provided at relevant scales and that decision-makers understand the causes and nature of risk in their constituencies. Focusing on a municipality in the Central Philippines, this study examines local meteorological information and explores household perceptions of climate change and coastal hazard risk. First, meteorological data and local perceptions of changing climate conditions are assessed. Perceived changes in climate include an increase in rainfall and rainfall variability, an increase in intensity and frequency of storm events and sea level rise. Second, factors affecting climate change perceptions and perceived risk from coastal hazards are determined through statistical analysis. Factors tested include social status, economic standing, resource dependency and spatial location. Results indicate that perceived risk to coastal hazards is most affected by households' spatial location and resource dependency, rather than socio-economic conditions. However, important differences exist based on the type of hazard and nature of risk being measured. Resource dependency variables are more significant in determining perceived risk from coastal erosion and sea level rise than flood events. Spatial location is most significant in determining households' perceived risk to their household assets, but not perceived risk to their livelihood.

RESUMEN

To report on a suspected case of idiopathic radiation recall dermatitis in an individual nine months after radiation and chemotherapy treatment of squamous cell carcinoma of the right tonsil. Radiation recall dermatitis is the development of a reaction in a previously irradiated area of skin after the administration of an aggravating medication. A review of the literature revealed several cases of radiation recall dermatitis that occur following radiation therapy and the institution of chemotherapy. Other medications have also been implicated in radiation recall dermatitis; however, this patient has not started any new medications since completion of his combined therapy. The patient developed this skin reaction in a distribution pattern identical to the area that received the highest radiation dose suggesting a possible link between radiation recall dermatitis and radiation dose. Radiation recall dermatitis is a reaction that is typically seen shortly after the reinstitution of chemotherapy during radiation therapy. This case illustrates that other medical etiologies are possible and suggests a relationship between radiation recall dermatitis and the total radiation dose an area receives.
