RESUMO

INTRODUCTION: Weight gain during chemotherapy for breast cancer is a well-documented adverse effect. The purpose of this study was to investigate how multidisciplinary weight management involving endocrinology, dietitian, and exercise physiology care, in a real-life healthy weight clinic (HWC) would impact body weight and mass composition in breast cancer women post-adjuvant chemotherapy compared to a cohort of non-cancer women who have been matched by age, ethnicity, smoking, and menopausal status. METHODS: Body weight (kg), BMI (kg/m2), skeletal muscle mass (SMM %), fat mass (FM %), and waist circumference (cm) were collected at baseline of the first HWC appointment, 3 months after baseline, and 6 months after baseline. A total of 32 women were included, 11 in the breast cancer cohort and 21 in the control cohort, that matched inclusion and exclusion criteria based on a retrospective chart review from 28 July 2017 to 19 July 2021. RESULTS: By 6 months, the breast cancer women had a mean weight change of -6.99 kg (SD = 3.87, p = 0.003, n = 11) and change in BMI by -2.72 kg/m2 (SD = 1.62, p = 0.004, n = 11). There was a change in SMM of 1.21% (SD = 0.73, p = 0.005, n = 11), a change in FM of -2.76% (SD = 1.33, p = 0.002, n = 11), and a change in waist circumference of -8.13 cm (SD = 4.21, p = 0.031, n = 3). By 6 months in the breast cancer cohort, there was a larger change in body weight in women who did not have MetS (-8.72 kg, SD = 2.41, n = 6) in comparison to women with MetS (-2.65 kg, SD = 3.75 kg, n = 3) (p = 0.045). CONCLUSION: Findings indicate that multidisciplinary weight management has a positive role in early-stage breast cancer survival through improving body weight and mass composition. These results can add to the development of long-term treatment plans for survivors in order to shine a light on ways to reduce risk recurrence and chronic disease mortality.

RESUMO

BACKGROUND: Smartphone apps have shown potential in enhancing weight management in Western populations in the short to medium term. With a rapidly growing obesity burden in Asian populations, researchers are turning to apps as a service delivery platform to reach a larger target audience to efficiently address the problem. OBJECTIVE: This systematic review and meta-analysis aims to determine the efficacy of interventions that incorporate apps in facilitating weight loss and health behavior change in the Asian population. METHODS: A total of 6 databases were searched in June 2020. The eligible studies included controlled trials in which an app was used in the intervention. The participants were aged 18 years or older and were of Asian ethnicity. A meta-analysis to test intervention efficacy, subgroup analyses, and post hoc analyses was conducted to determine the effects of adding an app to usual care and study duration. The primary outcome was absolute or percentage weight change, whereas the secondary outcomes were changes to lifestyle behaviors. RESULTS: A total of 21 studies were included in this review, and 17 (81%) were selected for the meta-analysis. The pooled effect size across 82% (14/17) of the randomized controlled trials for weight change was small to moderate (Hedges g=-0.26; 95% CI -0.41 to -0.11), indicating slightly greater weight loss achieved in the intervention group; however, this may not be representative of long-term studies (lasting for more than a year). Supplementing multicomponent usual care with an app led to greater weight loss (Hedges g=-0.28; 95% CI -0.47 to -0.09). Asian apps were largely culturally adapted and multifunctional, with the most common app features being communication with health professionals and self-monitoring of behaviors and outcomes. CONCLUSIONS: More evidence is required to determine the efficacy of apps in the long term and address the low uptake of apps to maximize the potential of the intervention. Future research should determine the efficacy of each component of the multicomponent intervention to facilitate the designing of studies that are most effective and cost-efficient for weight management.

RESUMO

Vaginal dilation, currently considered as the first-line therapy for vaginal aplasia in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, is a safe and effective treatment that aims to create a functional neovagina. However, rigid vaginal dilators classically described in the literature usually cause physical discomfort and side effects that can lead to vaginal necrosis. Here, we present two cases of MRKH syndrome patients with vaginal agenesis whose main complaint was the inability to have sexual intercourse with their partners. Considering unavailability of acrylic dilators and previous studies reporting good responses with the use of silicone dilators in women with post-radiotherapy vaginal stenosis, the medical team and patients opted for creation of a neovagina through the daily use of silicone vaginal dilators. Patient 1 developed an 8-cm vagina after 6 months of treatment and had a satisfactory sex life with her partner. Patient 2 developed a 7-cm vagina and reported significant symptom improvement. None of the patients developed side effects after the treatment. The use of inexpensive and easily accessible silicone vaginal dilators may be an effective and noninvasive alternative with few side effects for women with vaginal agenesis, particularly in the developing countries.

RESUMO

BACKGROUND: Young adults (18-35 years) remain among the lowest vegetable consumers in many western countries. The digital era offers opportunities to engage this age group in interventions in new and appealing ways. OBJECTIVE: This systematic review evaluated the efficacy and external validity of electronic (eHealth) and mobile phone (mHealth) -based interventions that promote vegetable intake in young adults. METHODS: We searched several electronic databases for studies published between 1990 and 2015, and 2 independent authors reviewed the quality and risk of bias of the eligible papers and extracted data for analyses. The primary outcome of interest was the change in vegetable intake postintervention. Where possible, we calculated effect sizes (Cohen d and 95% CIs) for comparison. A random effects model was applied to the data for meta-analysis. Reach and representativeness of participants, intervention implementation, and program maintenance were assessed to establish external validity. Published validation studies were consulted to determine the validity of tools used to measure intake. We applied the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to evaluate the overall quality of the body of evidence. RESULTS: Of the 14 studies that met the selection criteria, we included 12 in the meta-analysis. In the meta-analysis, 7 studies found positive effects postintervention for fruit and vegetable intake, Cohen d 0.14-0.56 (pooled effect size 0.22, 95% CI 0.11-0.33, I(2)=68.5%, P=.002), and 4 recorded positive effects on vegetable intake alone, Cohen d 0.11-0.40 (pooled effect size 0.15, 95% CI 0.04-0.28, I(2)=31.4%, P=.2). These findings should be interpreted with caution due to variability in intervention design and outcome measures. With the majority of outcomes documented as a change in combined fruit and vegetable intake, it was difficult to determine intervention effects on vegetable consumption specifically. Measurement of intake was most commonly by self-report, with 5 studies using nonvalidated tools. Longer-term follow-up was lacking from most studies (n=12). Risk of bias was high among the included studies, and the overall body of evidence was rated as low quality. The applicability of interventions to the broader young adult community was unclear due to poor description of external validity components. CONCLUSIONS: Preliminary evidence suggests that eHealth and mHealth strategies may be effective in improving vegetable intake in young adults; whether these small effects have clinical or nutritional significance remains questionable. With studies predominantly reporting outcomes as fruit and vegetable intake combined, we suggest that interventions report vegetables separately. Furthermore, to confidently establish the efficacy of these strategies, better-quality interventions are needed for young adults, using valid measures of intake, with improved reporting on costs, sustainability and long-term effects of programs.

RESUMO

INTRODUCTION: Smartphone lifestyle applications (apps) and wearable fitness-tracking devices collect a wealth of data that could provide research insights to support prevention and treatment of obesity and chronic diseases. The aim of this study was to pilot a survey to explore patterns of behavioral tracking using smartphone lifestyle apps and individuals' willingness to share their app-generated data. METHODS: A cross-sectional Web-based survey was conducted within a university setting. The 35-item survey asked participants about their self-tracking patterns; use of lifestyle apps and wearable devices; how their self-tracked health data could be useful to them; and any restrictions they would impose on sharing personal data. Responses were tabulated and analyzed for trends. RESULTS: The survey was completed by 101 participants. On average, 3.1 (standard deviation [SD] ±1.9) health and fitness apps were installed by current app users (n = 85), with MyFitnessPal, MapMyRun, Nike+, and Fitbit being most popular. Most participants were willing to share their personal health data for research (77%). Those who did not normally share their health-tracking data were more likely than sharers to be concerned about privacy (odds ratio [OR] = 5.93; 95% confidence interval [95% CI] = 2.09-16.78), as were those not identifying with the quantified-self movement compared with those who were (OR = 5.04; 95% CI = 1.64-15.50). DISCUSSION: Participants were generally willing to share personal data, thus increasing the potential for these data to inform public health research and for use in targeted personalized program and intervention development. CONCLUSIONS: Opportunities for partnerships between researchers and commercial app developers or industry could improve public health research and practice.

RESUMO

AIM: This review of systematic reviews synthesised evidence on the impact of dietary interventions on anthropometric and biochemical measures associated with schizophrenia and metabolic syndrome. Secondly, an aim to identify intervention elements associated with greater dietary adherence and behaviour change. METHODS: Five databases were searched from 2000-March 2023. Eligible reviews included adults, majority diagnosed with schizophrenia, dietary intervention components and at least one anthropometric or biochemical outcome related to metabolic syndrome. Two independent reviewers performed article selection, data extraction, and quality assessment. RESULTS: Seven systematic reviews, consisting of 79 unique primary papers were included. No reviews exclusively examined dietary interventions. Nutrition education and counselling administered alongside physical activity were common. All reviews favoured intervention over the control to reduce body weight, body mass index, and waist circumference. Glycaemic control, blood pressure and triglycerides were not routinely reported with mixed effects following interventions. There was insufficient data to examine any trends for dropout rates, dietary adherence, and behaviour change. There was both low (n = 3/7) and high (n = 4/7) risk of bias and degree of study overlap was very high (16.4 %). The level of evidence was rated as suggestive (n = 2/7), weak (n = 2/7), non-significant (n = 1/7) and ungraded (n = 2/7). CONCLUSION: Dietary interventions administered alongside lifestyle therapies can reduce anthropometric measurements for consumers living with schizophrenia and prescribed antipsychotic medications. Higher quality reviews with greater strength and credibility of evidence are required. Uniform reporting of intervention elements is also necessary for cross comparison of efficacious elements and synthesis of evidence at higher levels to advance dietetic practice and inform future policies.

RESUMO

BACKGROUND: The prevalence and healthcare cost of metabolic dysfunction-associated steatotic liver disease (MASLD) has increased alongside the epidemic surge in obesity and Type 2 diabetes. Weight loss through lifestyle modification remains the primary effective therapy for MASLD. Incorporation of mobile technology in lifestyle interventions has been previously found to be efficacious and cost-effective in facilitating weight loss. However, there is a paucity of studies that have successfully translated lifestyle research into clinical service for weight loss to alleviate disease burden. Our study aimed to describe the process of translating a mobile technology-enabled trial into a tertiary hospital outpatient dietetics service for patients with MASLD. METHODS: The Iowa Model of Evidence-Based Practice to Improve Quality Care was used as a framework for this paper to guide implementation at the organizational level. RESULTS: Regular engagement of key operational staff and the hospital management team facilitated open discussions of the challenges faced and enabled rapid implementation of strategies that contributed to the smooth piloting of the service. A service adoption rate of 81% was achieved. Preliminary outcome evaluation found that the percentage of patients achieving ≥ 5% weight loss from baseline at 6 months was comparable at 54% and 52% for the service and trial groups, respectively. CONCLUSIONS: Evaluation of the implementation process found that a hybrid model of care (in-person consultation supplemented with app coaching) preserved interpersonal connections while maximizing the convenience and scalability of mobile app-enabled service. Although high digital acceptance and adoption rates propelled by COVID-19-supported telehealth, it is prudent to assess patient's access to technology and digital literacy and offer resources to help them benefit from telehealth services.

RESUMO

AIM: This systematic review and meta-analysis aimed to investigate the impact of COVID19 lockdown on the anthropometric and glycaemic outcomes of adults with type 2 diabetes mellitus (T2DM) and assess whether socioeconomic status (SES) was relevant to these changes. METHODS: A search of three databases was conducted. Meta-analyses using random effects models were undertaken to combine anthropometric and glycaemic measures pre- and post-confinement. Subgroup analyses according to SES were also conducted. RESULTS: This systematic review of 19 articles demonstrated that prolonged pandemic-related confinement is associated with a deterioration in both anthropometric and glycaemic outcomes among adults with T2DM. Furthermore, SES was found to be relevant to these changes. Specifically, BMI (kg/m2) showed an increase in mean difference of 0.72 (95% CI; 0.13, 1.31; p<0.05) between pre and post lockdown cohorts. High income countries displayed a greater increase in BMI compared to their lower middle-income counterparts. Regarding, fasting blood glucose (FBG), a statistically significant difference was observed in the upper middle-income group (mean difference: 5.10; 95% CI: 2.92, 7.27), and high-income group (mean difference: 6.03; 95% CI: 0.04, 12.02). There were no significant changes to weight, waist circumference, or HbA1C over the lockdown period. CONCLUSION: Our findings suggest adults with T2DM may have received less effective care over the lockdown period, particularly in high income countries. Clinics and care providers may need to adopt more intensive contact and treatment plans in the post lockdown period to prevent lasting impacts on disease progression and metabolic sequelae.

RESUMO

There is a rising prevalence of non-communicable diseases (NCDs) in Papua New Guinea (PNG), adding to the disease burden from communicable infectious diseases and thus increasing the burden on the healthcare system in a low-resource setting. The aim of this review was to identify health and nutrition promotion programs conducted in PNG and the enablers and barriers to these programs. Four electronic databases and grey literature were searched. Two reviewers completed screening and data extraction. This review included 23 papers evaluating 22 health and nutrition promotion programs, which focused on the Ottawa Charter action areas of developing personal skills (12 programs), reorienting health services (12 programs) and strengthening community action (6 programs). Nineteen programs targeted communicable diseases; two addressed NCDs, and one addressed health services. Enablers of health promotion programs in PNG included community involvement, cultural appropriateness, strong leadership, and the use of mobile health technologies for the decentralisation of health services. Barriers included limited resources and funding and a lack of central leadership to drive ongoing implementation. There is an urgent need for health and nutrition promotion programs targeting NCDs and their modifiable risk factors, as well as longitudinal study designs for the evaluation of long-term impact and program sustainability.

RESUMO

While a large proportion of the population in Papua New Guinea (PNG) maintain a subsistence lifestyle, exposure to modernisation and industrialisation since European contact has influenced a transition towards Western diets. This review aimed to scope and summarise the published research on dietary intake among Pacific Islander adults in PNG. Four electronic databases and grey literature were searched. Two reviewers completed the screening and data extraction. Fourteen studies were included from the Highlands (n = 7), Southern (n = 5), Momase (n = 1) and both the Highlands/Southern region (n = 1). No studies were from the Islands region. The majority of the studies were published prior to the year 2000 (n = 9). Geographical region and degree of urbanisation had an impact on dietary intake. Urban areas reported higher intakes of energy, protein and fat compared to rural areas. In the Southern region, a variety of foods, including sago, taro, kaukau, cooked banana, coconut and cassava contributed to energy intake, while kaukau was the main energy and protein source in the Highlands. The main foods contributing to protein in the Southern region were fresh fish, land animals and purchased animals. This review highlights an evidence gap regarding dietary intake research. Within the context of international initiatives, there is an urgent call for research aimed at understanding the social and cultural contextualisation of dietary behaviours in PNG.

RESUMO

INTRODUCTION: The Finnish Geriatric Intervention Study (FINGER) led to the global dementia risk reduction initiative: World-Wide FINGERS (WW-FINGERS). As part of WW-FINGERS, the Australian AU-ARROW study mirrors aspects of FINGER, as well as US-POINTER. METHOD: AU-ARROW is a randomized, single-blind, multisite, 2-year clinical trial (n = 600; aged 55-79). The multimodal lifestyle intervention group will engage in aerobic exercise, resistance training and stretching, dietary advice to encourage MIND diet adherence, BrainHQ cognitive training, and medical monitoring and health education. The Health Education and Coaching group will receive occasional health education sessions. The primary outcome measure is the change in a global composite cognitive score. Extra value will emanate from blood biomarker analysis, positron emission tomography (PET) imaging, brain magnetic resonance imaging (MRI), and retinal biomarker tests. DISCUSSION: The finalized AU-ARROW protocol is expected to allow development of an evidence-based innovative treatment plan to reduce cognitive decline and dementia risk, and effective transfer of research outcomes into Australian health policy. Highlights: Study protocol for a single-blind, randomized controlled trial, the AU-ARROW Study.The AU-ARROW Study is a member of the World-Wide FINGERS (WW-FINGERS) initiative.AU-ARROW's primary outcome measure is change in a global composite cognitive score.Extra significance from amyloid PET imaging, brain MRI, and retinal biomarker tests.Leading to development of an innovative treatment plan to reduce cognitive decline.

RESUMO

BACKGROUND: Exercise is known to reduce adverse side effects of androgen-deprivation therapy (ADT) on quality of life, bone health and fatigue for prostate cancer (PCa) patients. We conducted a systematic review with meta-analysis to evaluate the effect of multidisciplinary interventions on body composition and metabolic syndrome (MetS) in ADT-treated PCa patients. METHODS: A systematic review and meta-analysis were conducted based on searches of EMBASE, MEDLINE, CENTRAL and Scopus databases from inception to March 2023. Participants included ADT-treated PCa patients who received multidisciplinary interventions including exercise, diet, nutrition, pharmacotherapy, bariatric surgery, or psychological/behavioural therapy. Primary outcomes were changes in body composition and MetS, with prostate-specific antigen (PSA) as a secondary outcome. After meta-analysis, results were reported in mean difference, 95% confidence interval and p-value, with forest plots. Additionally, we conducted subgroup analyses to compare the effect of different interventions. RESULTS: Thirty-three articles met the eligibility criteria out of 1443 articles and 28 studies were included in meta-analysis. Of 33 studies, 17 included exercise-only interventions and 10 included exercise + diet/nutrition interventions, but no studies included diet/nutrition-only interventions. All studies employed multidisciplinary approaches in developing or delivering the interventions. Most studies (85%) had low-moderate risk of bias, thus providing good evidence to this review. Overall, interventions had a positive effect on body composition measures; lean mass (LM):0.82 kg (95% CI:0.47,1.17;p < 0.00001), body fat mass (BFM):-0.68 kg (95% CI:-1.12,-0.24;p = 0.002), fat-free mass:0.75 kg (95% CI:0.14,1.37;p = 0.02) and body fat percentage (BFP):-0.99% (95% CI:-1.29,-0.68;p < 0.00001), as well as on MetS; waist circumference:-1.95 cm (95% CI:-3.10,-0.79;p = 0.0009), systolic blood pressure:-3.43 mmHg (95% CI:-6.36,-0.50;p = 0.02) and diastolic blood pressure:-2.48 mmHg (95% CI:-4.19,-0.76;p = 0.005). Subgroup-analyses showed that a combined approach including exercise + diet/nutrition was most effective in improving BFP, WC, SBP and DBP whereas exercise was more effective in improving LM and BFM. CONCLUSIONS: In ADT-treated PCa patients, multidisciplinary interventions, especially those combining exercise and diet/nutrition, can improve body composition and metabolic health.

RESUMO

Background: Non-communicable diseases (NCDs) are a major threat to health and development and account for 75% of deaths in the Pacific Islands Countries and Territories (PICTs). Childhood obesity has been identified as a main risk factor for NCDs later in life. This review compiled overweight and obesity (OWOB) prevalence (anthropometric data) for children aged six to 12 years old living in the Pacific region and identified possible related causes. Methods: We conducted a systematic search using PubMed, Google Scholar and ScienceDirect for articles published between January 1980 and August 2022. We also searched for technical reports from Ministries of Health. Guided by the eligibility criteria, two authors independently read the selected articles and reports to extract and summarise relevant information related to overweight and obesity. Results: We selected 25 articles, two worldwide analyses of population-based studies and four national reports. Information revealed that childhood OWOB prevalence reached 55% in some PICTs. This review also indicated that age, gender and ethnicity were linked to children's weight status, while dietary practices, sleep time and level of physical activity played a role in OWOB development, as well as the living environment (socio-economic status and food availability), parenting practices and education level. Conclusion: This review highlighted that anthropometric data are limited and that comparisons are difficult due to the paucity of surveys and non-standardized methodology. Main causes of overweight and obesity are attributed to individual characteristics of children and behavioural patterns, children's socio-economic environment, parenting practices and educational level. Reinforcement of surveillance with standardised tools and metrics adapted to the Pacific region is crucial and further research is warranted to better understand root causes of childhood OWOB in the Pacific islands. More robust and standardized anthropometric data would enable improvements in national strategies, multisectoral responses and innovative interventions to prevent and control NCDs.


In the Pacific region, populations have gained faster access to modern lifestyles in the past few decades, causing fundamental changes in the way people move about and eat (including food choices, physical activity, and sedentary time) and a dramatic increase in noncommunicable diseases. This is mainly the case in young generations since they are particularly exposed to an environment that can drive to overweight and obesity. This scoping review aims to summarize the prevalence and known causes of overweight and obesity for children aged six to 12 years old living in the Pacific region and identified possible related factors. This work highlighted that causes of overweight and obesity are mainly attributed to individual characteristics of children and behavioural patterns, children's socio-economic environment, parenting practices and educational level.

RESUMO

Single-molecule localization microscopy enables three-dimensional fluorescence imaging at tens-of-nanometer resolution, but requires many camera frames to reconstruct a super-resolved image. This limits the typical throughput to tens of cells per day. While frame rates can now be increased by over an order of magnitude, the large data volumes become limiting in existing workflows. Here we present an integrated acquisition and analysis platform leveraging microscopy-specific data compression, distributed storage and distributed analysis to enable an acquisition and analysis throughput of 10,000 cells per day. The platform facilitates graphically reconfigurable analyses to be automatically initiated from the microscope during acquisition and remotely executed, and can even feed back and queue new acquisition tasks on the microscope. We demonstrate the utility of this framework by imaging hundreds of cells per well in multi-well sample formats. Our platform, implemented within the PYthon-Microscopy Environment (PYME), is easily configurable to control custom microscopes, and includes a plugin framework for user-defined extensions.

RESUMO

Knowing the type and quality of the most popular foods consumed by a population can be useful in the design of technologies for monitoring food intake and interventions. The aim of this research was to determine the most frequently consumed foods and beverages among the Australian population and provide recommendations for progressing the design of dietary assessment technologies. Analysis of the first 24 h recall of the most recent Australian National Nutrition and Physical Activity Survey was conducted. The most popular foods and beverages consumed by energy (kJ) and by frequency were calculated. There were 4515 separate foods and beverages reported by 12,153 people. Overall, the top 10 foods that contributed most energy included full fat milk, beer, white rice, white bread, red wine, cola soft drinks, bananas, red apples, wholewheat breakfast cereal and white sugar. The five most frequently reported foods and beverages were tap water, black tea, full fat milk, instant coffee, and sugar. Understanding the most popular foods and beverages consumed can support innovations in the design of digital tools for dietary surveillance and to reduce under-reporting and food omissions. These findings could also guide the development of more tailored and relevant food databases that underpin these technologies.

RESUMO

With the global rise in obesity and the metabolic syndrome, double diabetes is increasingly prevalent in patients with type 1 diabetes. This review investigated the effects of diet on weight management and metabolic outcomes in patients with double diabetes. MEDLINE, CENTRAL, EMBASE, PsycINFO, CINAHL, ERIC, and Web of Science databases were searched through September 2020. Population- or individual-level dietary interventions, and observational studies investigating dietary patterns in adults with type 1 diabetes and overweight or obesity, were eligible for inclusion. The quality of studies was assessed. Four eligible studies were included in this review, comprising two randomized controlled trials, one pretest-posttest study, and one cross-sectional study. Study populations included between 10 and 1040 participants. Dietary interventions included the Mediterranean diet, low-fat diet, intermittent fasting, continuous energy restriction, and a combination of fasting and a standardized low-calorie diabetic diet (LCD). Significant weight loss was observed within groups for low-fat diet, Mediterranean diet, fasting, LCD with fasting, intermittent fasting, or continuous energy restriction, but there were no between-group differences. Weight maintenance was only achieved in interventions where fasting or intermittent fasting were present. Dietary interventions in published data failed to demonstrate effects on metabolic syndrome. Larger sample, high-quality trials conducted over longer periods are urgently required to determine the efficacy of diet for weight management and improving metabolic outcomes in individuals with double diabetes. This would provide much needed evidence-based guidance for dietary interventions, which are well known to be the cornerstone of clinical care.

RESUMO

Despite the obesity epidemic, there are relatively few multidisciplinary obesity services in Australia, and only limited data on the effectiveness of these services. The aim of this study was to evaluate the effectiveness of a university hospital-based weight management clinic-the 'Healthy Weight Clinic' in supporting patients to achieve clinically significant weight loss (≥5% reduction in body weight), weight maintenance, and changes in body composition. A retrospective review was conducted to determine weight and associated health outcomes in patients who attended an initial consultation in the first 2 years of the clinic-between March 2017 and March 2019. Follow up was at least 1 year for all patients. Patients who underwent bariatric surgery were excluded. Of 213 total patients, 172 patients attended more than one follow-up consultation for lifestyle modification. Mean weight change and percentage total weight change at last follow-up was -6.2 kg (SD 7.4) and - 6.0% (SD 6.9), respectively. For every additional clinic follow-up, there was 21.4% increased odds of achieving clinically significant weight loss, and for every additional month of follow-up, there was 10.1% increased odds of achieving clinically significant weight loss. Twenty percent of patients (34/172) maintained ≥5% of initial body weight loss for at least 1 year. Body composition measurements were also favourable, with significant changes in percentage skeletal muscle mass of +0.8% (SD 1.5) and in percentage fat mass by -1.4% (SD 3.2). Regular support in a structured holistic multidisciplinary obesity service enables patients to achieve clinically meaningful weight loss and improved skeletal muscle mass to body fat ratio, and maintain this loss for at least 1 year. Improved weight loss was associated with more patient visits and longer duration of attendance at the clinic.

RESUMO

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is the putative cause of coronavirus disease 2019 (COVID-19), a serious disease that has severely impacted the world. Although vaccines have been developed, it will take time to inoculate the global population. Current guidelines have focused on the treatment of severe cases in hospital settings; however, a void has been created regarding appropriate measures for those in the initial stage of COVID-19 and those experiencing moderate disease severity progressing to desaturation. We assessed clinical outcomes in patients with COVID-19 with pneumonia at initial presentation treated with corticosteroids. Methods: Data of 177 consecutive high-risk patients with COVID-19, monitored by telemedicine, were collected and analyzed. Of those, 68 patients were in the initial inflammatory phase of the disease without desaturation and received corticosteroids. The outcomes were evaluated after a follow up of 14 days. Four patients were immediately referred to the hospital because they had explicit desaturation at presentation. Results: After 14 days, all patients in the inflammatory phase at presentation who were treated with corticosteroids before desaturation were alive and without complications. However, of the four patients with desaturation, one died at the hospital. Conclusion: In this study, the use of corticosteroids during the initial pulmonary phase of COVID-19 before desaturation, in addition to daily monitoring of patients, prevented disease progression, decreased the risk of complications and incidence of hospitalization and death. However, additional studies with larger number of patients are needed to confirm these findings.

RESUMO

The study of food consumption, diet, and related concepts is motivated by diverse goals, including understanding why food consumption impacts our health, and why we eat the foods we do. These varied motivations can make it challenging to define and measure consumption, as it can be specified across nearly infinite dimensions-from micronutrients to carbon footprint to food preparation. This challenge is amplified by the dynamic nature of food consumption processes, with the underlying phenomena of interest often based on the nature of repeated interactions with food occurring over time. This complexity underscores a need to not only improve how we measure food consumption but is also a call to support theoreticians in better specifying what, how, and why food consumption occurs as part of processes, as a prerequisite step to rigorous measurement. The purpose of this Perspective article is to offer a framework, the consumption process framework, as a tool that researchers in a theoretician role can use to support these more robust definitions of consumption processes. In doing so, the framework invites theoreticians to be a bridge between practitioners who wish to measure various aspects of food consumption and methodologists who can develop measurement protocols and technologies that can support measurement when consumption processes are clearly defined. In the paper we justify the need for such a framework, introduce the consumption process framework, illustrate the framework via a use case, and discuss existing technologies that enable the use of this framework and, by extension, more rigorous study of consumption. This consumption process framework demonstrates how theoreticians could fundamentally shift how food consumption is defined and measured towards more rigorous study of what, how, and why food is eaten as part of dynamic processes and a deeper understanding of linkages between behavior, food, and health.

RESUMO

BACKGROUND: There are concerns that tamoxifen is less effective in Asian women because of the high prevalence of impaired function cytochrome P450 2D6 (CYP2D6) polymor-phisms. AIM: To evaluate how knowledge of CYP2D6 genotype impacted the choice of hormonal agent and how CYP2D6 genotype and agent were associated with clinical outcomes. METHODS: Eighty-two women were recruited. Seventy-eight completed CYP2D6 genotyping and were categorized into poor, intermediate (IM) and extensive or ultra metabolizer phenotypes. Women with poor metabolizer and IM phenotypes were recommended aromatase inhibitors as the preferred agent. RESULTS: More than 70% of the women had an IM phenotype, 32% an extensive or ultra metabolizer phenotype, and 0% had a poor metabolizer phenotype. Regardless of genotype, more women opted for aromatase inhibitors. Overall, 80% of women completed 5 years of hormonal therapy. Five women developed recurrence, 3 contralateral breast cancer, 5 died, and 1 was diagnosed with a second primary cancer. Five-year recurrence-free and overall survival were slightly better in women with the extensive or ultra metabolizer phenotype compared to those with the IM phenotype, though not statistically significant [P = 0.743, hazard ratio (HR): 1.441, 95% confidence interval (CI): 0.191 to 10.17 and P = 0.798, HR: 1.327, 95%CI: 0.172 to 9.915, respectively]. Women receiving aromatase inhibitors also appeared to have a better, but also nonsignificant, 5-year recurrence-free and overall survival (P = 0.253, HR: 0.368, 95%CI: 0.031 to 0.258 and P = 0.292, HR: 0.252, 95%CI: 0.005 to 4.951, respectively). CONCLUSION: The IM phenotype was highly prevalent but was not associated with clinical outcome.
