ABSTRACT

BACKGROUND: Recent studies have demonstrated that real-time CGM use reduce the incidence severe hypoglycemic events and impaired awareness of hypoglycemia (IAH) However, there are few real-world studies evaluating the effect of intermittently scanned continuous glucose monitoring (isCGM) on hypoglycemic episodes and hypoglycemia unawareness (IAH). The present study was designed to cover this research-practice gap. METHODS: This is a real-world, observational, prospective cohort study with 2 years of follow-up in which 60 subjects with T1D who experienced frequent hypoglycemic events were included. All the patients were invited to use isCGM type Abbott FreeStyle Libre 2® on a continuous basis for 2 years. Glucometric parameters were obtained during the initial 2 weeks using isCGM and compared with data collected for the same period at 1 year and at the end of follow-up. The IAH was evaluated using the Clarke questionnaire, and to assess psychological aspects related to hypoglycemia the Hypoglycemia Fear Survey (HFS) was used. RESULTS: After 2-years of follow-up using isCGM, we observed a decrease in glucose variability (40.3 ± 0.8 % vs. 37.1 ± 0.9 %, p = 0.003), time in low glucose range (54-69 mg/dL) (5.2 ± 0.4 % vs. 3.6 ± 0.3 %, p = 0.001), time in very low glucose range (<54 mg/dL) (3.2 ± 0.5 % vs. 0.8 ± 0.2 %, p < 0.001), less events related to low glucose levels (10.6 ± 1.1 vs 8.0 ± 1.0, p = 0.042) and a short duration of hypoglycemia episodes (106.1 ± 5.9 min vs. 85.7 ± 5.7 min, p = 0.008). In addition, participants presented a reduction of 47 % in the frequency of IAH, assessed by the Clarke questionnaire scores (24.6 % vs. 11.6 %, p = 0.034), as well as hypoglycemia fear (77.8 ± 2.4 vs 68.2 ± 2.1, p < 0.001). Furthermore, a reduction in total insulin dose was also observed (0.64 ± 0.30 UI/Kg/day vs 0.56 ± 0.11 UI/Kg/day, p = 0.018). CONCLUSIONS: In the real-world, long-term use of isCGM could reduce both hypoglycemic episodes and IAH in people with T1D.

ABSTRACT

The interactions of environmental, geographic, socio-demographic, and epidemiological factors in shaping mosquito-borne disease transmission dynamics are complex and changeable, influencing the abundance and distribution of vectors and the pathogens they transmit. In this study, 27 years of cross-sectional malaria survey data (1990-2017) were used to examine the effects of these factors on Plasmodium falciparum and Plasmodium vivax malaria presence at the community level in Africa and Asia. Monthly long-term, open-source data for each factor were compiled and analyzed using generalized linear models and classification and regression trees. Both temperature and precipitation exhibited unimodal relationships with malaria, with a positive effect up to a point after which a negative effect was observed as temperature and precipitation increased. Overall decline in malaria from 2000 to 2012 was well captured by the models, as was the resurgence after that. The models also indicated higher malaria in regions with lower economic and development indicators. Malaria is driven by a combination of environmental, geographic, socioeconomic, and epidemiological factors, and in this study, we demonstrated two approaches to capturing this complexity of drivers within models. Identifying these key drivers, and describing their associations with malaria, provides key information to inform planning and prevention strategies and interventions to reduce malaria burden.

ABSTRACT

BACKGROUND: A large number of modifiable and measurable daily actions are thought to impact mental health. The "Things You Do" refers to 5 types of daily actions that have been associated with mental health: healthy thinking, meaningful activities, goals and plans, healthy habits, and social connections. Previous studies have reported the psychometric properties of the Things You Do Questionnaire (TYDQ)-21-item (TYDQ21). The 21-item version, however, has an uneven distribution of items across the 5 aforementioned factors and may be lengthy to administer on a regular basis. OBJECTIVE: This study aimed to develop and evaluate a brief version of the TYDQ. To accomplish this, we identified the top 10 and 15 items on the TYDQ21 and then evaluated the performance of the 10-item and 15-item versions of the TYDQ in community and treatment-seeking samples. METHODS: Using confirmatory factor analysis, the top 2 or 3 items were used to develop the 10-item and 15-item versions, respectively. Model fit, reliability, and validity were examined for both versions in 2 samples: a survey of community adults (n=6070) and adults who completed an assessment at a digital psychology service (n=14,878). Treatment responsivity was examined in a subgroup of participants (n=448). RESULTS: Parallel analysis supported the 5-factor structure of the TYDQ. The brief (10-item and 15-item) versions were associated with better model fit than the 21-item version, as revealed by its comparative fit index, root-mean-square error of approximation, and Tucker-Lewis index. Configural, metric, and scalar invariance were supported. The 15-item version explained more variance in the 21-item scores than the 10-item version. Internal consistency was appropriate (eg, the 15-item version had a Cronbach α of >0.90 in both samples) and there were no marked differences between how the brief versions correlated with validated measures of depression or anxiety symptoms. The measure was responsive to treatment. CONCLUSIONS: The 15-item version is appropriate for use as a brief measure of daily actions associated with mental health while balancing brevity and clinical utility. Further research is encouraged to replicate our psychometric evaluation in other settings (eg, face-to-face services).

ABSTRACT

OBJECTIVE: The objective of this study was to determine the proportion of all published core outcome set (COS) studies that include an adverse event or harm outcome, to determine the proportion of individual versus pooled harms, and to investigate characteristics that influence their inclusion. METHODS: We examined the extent to which a sample of 100 published COS studies (from January 2021 to January 2023) include both pooled and individual harms in the final COS. One investigator extracted the information from the COS studies, which was cross-checked against previous COS investigational research, and where possible verified with COS authors or a pharmacologist. Using QualtricsTM, we conducted a personalised online survey of developers of the 100 COS to ask them about the importance, their experiences, and methodological approaches for dealing with harms within their COS development studies. RESULTS: One hundred COS were identified from 91 separate COS studies, the majority of which considered most of the minimum standards for development. Two-thirds (65%) of the COS included at least one harm outcome. In total, 1104 core outcomes were identified across the 100 COS, of which 184 (17%) were harm outcomes (154 individual vs. 56 pooled). Individual harms were more likely to be included in a final COS if they were developed for single treatment interventions (50%) compared to those being developed for multi-treatment modalities (39%). Some COS developers adopted outcome frameworks as part of their COS development process to facilitate the inclusion of harm outcomes in their final COS. A third (33%) of respondents felt that harm outcomes should be included in all COS but over half (56%) thought this would be dependent on some aspect of the scope of the COS and improved methodology and awareness of how to deal with harm outcomes in the COS development process. CONCLUSION: Harm outcomes are already included in many COS either as individual or pooled harms. It is evident that there are some challenges with regards to both the methodology and necessity to include harms within a COS (pooled or individual. COS developers should carefully consider the need to include important harms outcomes in relation to the scope of the COS that they are developing.

ABSTRACT

BACKGROUND: Foot complications in diabetes are common and destructive, resulting in substantial healthcare costs and high rates of morbidity. Coastal areas have a significantly higher burden of disease. People with diabetes experience disproportionately high rates of psychological health issues, including anxiety, depression and diabetes distress. These can affect self-management and concordance with preventive measures and treatments of foot complications, negatively impacting on outcomes. Access to psychological health services is variable across the United Kingdom and there is a paucity of high-quality evidence for the effectiveness of treatments for diabetes distress. This study aimed to explore experiences of psychosocial burden and perceptions and experiences of psychosocial support, among patients with diabetes and foot complications living in a coastal area. METHODS: Patients were eligible to participate if they had experienced diabetes-related foot complications (amputation, ulceration and/or Charcot neuroarthropathy) within the last 5 years and scored positive for diabetes distress on a validated screening tool (DDS2). Eligible patients completed cross-sectional questionnaires describing symptoms of diabetes distress (DDS17), anxiety (GAD-7) and depression (PHQ-9) and to take part in a face-to-face, semi-structured interview. Questionnaires were analysed using frequencies and interviews were analysed using reflexive thematic analysis. RESULTS: A total of 183 patients completed the DDS2 screening questionnaire. Of these, 56 (30.6%) screened positive for diabetes distress. Twenty-seven patients completed DDS17, GAD-7 and PHQ-9 questionnaires. Eleven (40.7%) participants indicated high levels of diabetes distress and four (14.8%) indicated moderate distress. Seventeen participants (age range 52-81 years; 12 men) took part in an interview. Four key themes were identified: impact of living with foot problems; emotional consequences of foot problems; experiences and perceptions of psychological support; and strategies to cope with the emotional impact of foot problems. CONCLUSION: Diabetes distress was prevalent among patients with diabetes-related foot complications. Foot problems impacted on participants' daily activities, social lives and ability to work. Despite expressing feelings of ongoing fear, worry and depression relating to their foot problems, only one participant had accessed formal psychological support. Many participants relied on talking to podiatrists at routine appointments and described developing various strategies to cope. The psychosocial burden of living with foot complications in diabetes must not be overlooked by health professionals. Findings from this study can inform the design of future services and interventions.

ABSTRACT

Carceral conditions in the United States may serve as a proxy for crises within justice and health systems. This study seeks to consider and measure prison climate from the perspective of incarcerated people. By examining within-facility differences in carceral experiences, results shed light on the complex nexus between the carceral context, health, and justice. We administered the Prison Climate Questionnaire (PCQ) to the complete population of incarcerated men in a correctional facility located in the Eastern United States. In this facility, housing units hold distinct populations, fulfill different functions, and can offer unique programming. We regress select items from the PCQ on a set of dummies corresponding to different residential units within the facility. Responses indicate low but relatively uniform perceptions of overall personal health, as well as access to, and satisfaction with, medical care. Between-unit differences emerge regarding staff relationships, experiences of discrimination, and levels of isolation. The perspectives of incarcerated people can, and should, play a role in understanding and conceptualizing the nature of the prison environment. Policy responses, especially those that impact the health and well-being of currently and formerly incarcerated people, can be informed by these perspectives.

ABSTRACT

OBJECTIVE: To identify current practices in the management of selective fetal growth restriction (sFGR) in monochorionic diamniotic (MCDA) twin pregnancies. DESIGN: Cross-sectional survey. SETTING: International. POPULATION: Clinicians involved in the management of MCDA twin pregnancies with sFGR. METHODS: A structured, self-administered survey. MAIN OUTCOME MEASURES: Clinical practices and attitudes to diagnostic criteria and management strategies. RESULTS: Overall, 62.8% (113/180) of clinicians completed the survey; of which, 66.4% (75/113) of the respondents reported that they would use an estimated fetal weight (EFW) of <10th centile for the smaller twin and an inter-twin EFW discordance of >25% for the diagnosis of sFGR. For early-onset type I sFGR, 79.8% (75/94) of respondents expressed that expectant management would be their routine practice. On the other hand, for early-onset type II and type III sFGR, 19.3% (17/88) and 35.7% (30/84) of respondents would manage these pregnancies expectantly, whereas 71.6% (63/88) and 57.1% (48/84) would refer these pregnancies to a fetal intervention centre or would offer fetal intervention for type II and type III cases, respectively. Moreover, 39.0% (16/41) of the respondents would consider fetoscopic laser surgery (FLS) for early-onset type I sFGR, whereas 41.5% (17/41) would offer either FLS or selective feticide, and 12.2% (5/41) would exclusively offer selective feticide. For early-onset type II and type III sFGR cases, 25.9% (21/81) and 31.4% (22/70) would exclusively offer FLS, respectively, whereas 33.3% (27/81) and 32.9% (23/70) would exclusively offer selective feticide. CONCLUSIONS: There is significant variation in clinician practices and attitudes towards the management of early-onset sFGR in MCDA twin pregnancies, especially for type II and type III cases, highlighting the need for high-level evidence to guide management.

ABSTRACT

PURPOSE: To examine which workplace factors contribute to health care leader well-being in rural settings. METHODS: Working with two rurally focused organizations, we administered a Rural Leader Burnout survey to executive leaders. The survey contained 25 questions; 24 were closed-item multiple choice and 1 open-ended question. The survey was based on the Mini Z 10 item burnout survey with 5 additional items for leaders. Logistic regression and qualitative content analysis determined factors associated with job satisfaction, burnout, and intent to leave (ITL). FINDINGS: There were 288 respondents (response rate 22%). Of 272 with complete data, 61.4% were women and 51.8% had worked > 10 years. About 81% reported job satisfaction, 40.2% were burned out, and 49.8% intended to leave their administrative roles within 2 years. Factors statistically associated with satisfaction were work control (OR = 3.0), values alignment with leadership (OR = 2.1), and trust in organization (OR = 2.0). Work control (OR = 0.3), trust in organization (OR = 0.4), and stress (OR = 4.1) were associated with burnout. Trust in organization (OR = 0.5), feeling valued (OR = 0.6), and stress (OR = 1.8) associated with ITL. Qualitative data revealed three themes relevant to rural leaders: (1) industry challenges, (2) daily operational issues, and (3) difficult relationships. CONCLUSIONS: These exploratory analyses demonstrate practical ways to improve work conditions to mitigate burnout and turnover in rural leaders. Promoting thriving in leaders would be an important step in maintaining the rural health care workforce.

ABSTRACT

Numerous studies have identified religious correlates of health indicators, but relatively few have been conducted among Jewish populations in Israel or the diaspora. This study investigates the possibility of a religious gradient in physical and mental health and well-being across the familiar categories of Jewish religious identity and observance in Israel: hiloni (secular), masorti lo dati (traditional, non-religious), masorti (traditional), dati (religious or Orthodox), and charedi (ultra-Orthodox). Data are from Jewish respondents aged 18 and over (N = 2916) from the Israeli sample of the new, 22-nation Global Flourishing Study, which used stratified, probability-based sampling and assessed demographic, socioeconomic, political, religious, health-related, and other variables. This analysis investigated religious differences in nine indicators of physical and mental health and well-being among Israeli Jews. Using a strategy of one-way ANOVA and ANCOVA, adjusting for complex sampling design components, a statistically significant "dose-response"-like gradient was found for eight of the outcome measures, validated by additional multiple comparison tests. For four "positively" worded indicators (physical and mental health, happiness, and life satisfaction), scores increased consistently from the hiloni to the charedi categories. For four of five "negatively" worded indicators (bodily pain, depression, anxiety, and suffering), scores decreased across the same categories. Results withstood adjusting for effects of age, sex, education, marital status, urbanicity, income, and nativity (whether born in Israel). Among Israeli Jews, greater religiousness was associated with higher levels of health and well-being and lower levels of somatic and psychological distress.

ABSTRACT

BACKGROUND AND OBJECTIVES: If the proportion of calcium intake over a whole day is related to the risk of cognitive impairment in adults is still largely unknown. This research aimed to examine the relation of dietary calcium intake at dinner versus breakfast with the risk of cognitive impairment by using data from the China Health and Nutrition Survey (CHNS). METHODS AND STUDY DESIGN: A total of 2,099 participants (including 668 cognitive impairment) in the CHNS (1997-2006) were included. The participants were categorized into 5 groups in accordance with the ratio of dietary calcium intake at dinner and breakfast (Δ = dinner/breakfast). After adjustment was conducted for a series of confounding factors, Cox hazard regression modelling was performed to discuss the relation of Δ with cognitive impairment. Dietary substitution models were used to explore the changes in cognitive impairment risk when a 5% dietary calcium intake at dinner was replaced with dietary calcium intake at breakfast. RESULTS: Participants in the highest distribution of Δ showed a greater susceptibility to cognitive impairment than those in the lowest quintile, with an adjusted hazard ratio of cognitive impairment of 1.38 (95% CI: 1.08-1.76). When maintaining total calcium intake, substituting 5% of dietary calcium intake at dinner with calcium intake at breakfast was related to an 8% decrease in the risk of cognitive impairment. CONCLUSIONS: Higher dietary calcium intake at dinner was associated with an increased risk of cognitive impairment, emphasizing the importance of appropriately distributing dietary calcium intake between breakfast and dinner.

ABSTRACT

BACKGROUND AND OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) has become a worldwide public health problem. Current evidence on the association between dietary iron intake and the risk of NAFLD is limited. The present study aimed to investigate the associations of animal-derived dietary iron (ADDI) intake, plant-derived dietary iron (PDDI) intake, and the ratio of PDDI:ADDI with NAFLD risk among U.S. adult population. METHODS AND STUDY DESIGN: This was a repeated cross-sectional study. Data were collected from the National Health and Nutrition Examination Survey (NHANES) 2007-2018. NAFLD was defined as a United States Fatty Lives Index ≥30, and dietary iron intake was assessed through two 24-h dietary recall in-terviews. Logistic regression and restricted cubic spline models were applied to examine the associations between dietary iron intake from different sources and NAFLD risk. RESULTS: A total of 9478 participants aged ≥20 years were enrolled in the present study. After adjustment for multiple confounding factors, relative to the lowest quartile, the odds ratio (OR) and 95% confidence interval (CI) of NAFLD for the highest quartile was 1.01(95% CI, 0.82-1.24) for ADDI intake, 0.82 (95% CI, 0.64-0.99) for PDDI intake, and 1.00 (95% CI, 0.81-1.24) for the PDDI: ADDI intake ratio. In stratified analysis by sex and age, the significantly negative associations of PDDI intake with NAFLD was observed in women and participants older than 45 years. Dose-response analyses indicated that NAFLD was negatively associated with PDDI intake in a non-linear manner. CONCLUSIONS: PDDI intake was negatively associated with NAFLD in U.S. adults.

ABSTRACT

Multiple sclerosis (MS) is uncommon in China and the standard of care is underdeveloped, with limited utilization of disease-modifying treatment (DMT). An understanding of real-world disease burden (including direct medical, non-medical, and indirect costs, such as loss of productivity), is currently lacking in this population. To investigate the overall burden of managing patients with MS in China, a cross-sectional survey of physicians and their consulting patients with MS was conducted in 2021. Physicians provided information on healthcare resource utilization (HCRU; consultations, hospitalizations, tests, medication) and associated costs. Patients provided data on changes in their life, productivity, and impairment of daily activities due to MS. Results were stratified by disease severity using generalized linear models, with a p value < 0.05 considered statistically significant. Patients with more severe disease had greater HCRU, including hospitalizations, consultations and tests/scans, and incurred higher direct and indirect costs and productivity loss, compared with those with milder disease. However, the use of DMT was higher in patients with mild disease severity. With the low uptake and limited efficacy of non-DMT drugs, Chinese patients with MS experience a high disease burden and significant unmet needs. Therapeutic interventions could help save downstream costs and lessen societal burden.

ABSTRACT

OBJECTIVES: This study aims to determine the awareness levels and factors affecting it, along with prevalent misconceptions about Steatotic Liver Disease (SLD) among participants with high-risk indicators. METHODS: A questionnaire with open-ended questions was utilized. Participants were recruited from two general internal medicine outpatient clinics, focusing on those with high-risk indicators for SLD. Data collection involved a questionnaire covering demographic information, self-reported clinical conditions, and open-ended questions about SLD awareness. Key focus areas included misconceptions, thematic awareness, and the relationship between awareness and educational attainment. RESULTS: The study involved 228 participants, predominantly female (70.4%), with an average age of 53.8 years. Only 33.7% showed a comprehensive understanding of all aspects of SLD. However, 90.4% provided some accurate information, though often limited or incomplete. Higher education and awareness of SLD risks were key predictors of better understanding. The logistic regression model, with an accuracy of 0.76 and recall of 0.84, found higher education inversely related to low awareness. Common misconceptions highlighted included the belief that polypharmacy or certain medications cause SLD, fatigue as an effect, and increased water intake as a treatment. Notably, seven patients mentioned artichoke consumption as a potential treatment. CONCLUSION: The findings highlight the gap between comprehensive and partial awareness of SLD among high-risk individuals. Educational level and informed understanding of SLD risks are crucial for improving awareness, emphasizing the need for specialized educational efforts and risk communication to high-risk patients.

ABSTRACT

Low-frequency electromagnetic induction (EMI) is a non-invasive geophysical method that is based on the induction of electromagnetic (EM) waves into the subsurface to quantify changes in electrical conductivity. In this study, we present an open (design details and software are accessible) and modular system for the collection of EMI data. The instrument proposed allows for the separations between the transmitter to be adjusted and up to four receiving antennas as well as the acquisition frequency (in the range between 3 and 50 kHz) to permit measurements with variable depth of investigation. The sensor provides access to raw data and the software described in this study allows control of the signal processing chain. The design specifications permit apparent conductivity measurements in the range of between 1 mS/m and 1000 mS/m, with a resolution of 1.0 mS/m and with a sampling rate of up to 10 samples per second. The sensor allows for a synchronous acquisition of a time stamp and a location stamp for each data sample. The sensor has a mass of less than 5 kg, is portable and suitable for one-person operation, provides 4 h of operation time on one battery charge, and provides sufficient rigidity for practical field operations.

ABSTRACT

The use of magnetometers arranged in a gradiometer configuration offers a practical and widely used solution, particularly in archaeological applications where the sources of interest are generally shallow. Since magnetic anomalies due to archaeological remains often have low amplitudes, highly sensitive magnetic sensors are kept very close to the ground to reveal buried structures. However, the deployment of Unmanned Aerial Vehicles (UAVs) is increasingly becoming a reliable and valuable tool for the acquisition of magnetic data, providing uniform coverage of large areas and access to even very steep terrain, saving time and reducing risks. However, the application of a vertical gradiometer for drone-borne measurements is still challenging due to the instability of the system drone magnetometer in flight and noise issues due to the magnetic interference of the mobile platform or related to the oscillation of the suspended sensors. We present the implementation of a magnetic vertical gradiometer UAV system and its use in an archaeological area of Southern Italy. To reduce the magnetic and electromagnetic noise caused by the aircraft, the magnetometer was suspended 3m below the drone using ropes. A Continuous Wavelet Transform analysis of data collected in controlled tests confirmed that several characteristic power spectrum peaks occur at frequencies compatible with the magnetometer oscillations. This noise was then eliminated with a properly designed low-pass filter. The resulting drone-borne vertical gradient data compare very well with ground-based magnetic measurements collected in the same area and taken as a control dataset.

ABSTRACT

AIM: To test the influences of patient, safety event and nurse characteristics on nurse judgements of credibility, importance and intent to report patients' safety concerns. DESIGN: Factorial survey experiment. METHODS: A total of 240 nurses were recruited and completed an online survey including demographic information and responses to eight factorial vignettes consisting of unique combinations of eight patient and event factors. Hierarchical multivariate analysis was used to test influences of vignette factors and nurse characteristics on nurse judgements. RESULTS: The intraclass coefficients for nurse judgements suggest that the variation among nurses exceeded the influence of contextual vignette factors. Several significant sources of nurse variation were identified, including race/ethnicity, suggesting a complex relationship between nurses' characteristics and their potential biases, and the influence of personal and patient factors on nurses' judgements, including the decision to report safety concerns. CONCLUSION: Nurses are key players in the system to manage patient safety concerns. Variation among nurses and how they respond to scenarios of patient safety concerns highlight the need for nurse-level intervention. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Complex factors influence nurses' judgement, interpretation and reporting of patients' safety concerns. IMPACT: Understanding nurse judgement regarding patient-expressed safety concerns is critical for designing processes and systems that promote reporting. Multiple event and patient characteristics (type of event and apparent harm, and patient gender, race/ethnicity, socioeconomic status, and communication approach) as well as participant characteristics (race/ethnicity, gender, years of experience and primary hospital area) impacted participants' judgements of credibility, degree of concern and intent to report. These findings will help guide patient safety nurse education and training. REPORTING METHOD: STROBE guidelines. PATIENT OR PUBLIC CONTRIBUTION: Members of the public, including patient advocates, were involved in content validation of the vignette scenarios, norming photographs used in the factorial survey and testing the survey functionality.

ABSTRACT

To reduce micronutrient deficiencies, Senegal mandates the fortification of refined oil with vitamin A and wheat flour with iron and folic acid. Expanding Senegal's large-scale food fortification programs to include fortified bouillon could help fill the remaining gaps in dietary micronutrient requirements. Using 7-day household food consumption data collected between 2018 and 2019, we assessed the potential contributions of bouillon fortified with vitamin A (40-250 µg/g bouillon), folic acid (20-120 µg/g), vitamin B12 (0.2-2 µg/g), iron (0.6-5 mg/g), and zinc (0.6-5 mg/g) for meeting micronutrient requirements of women of reproductive age (WRA; 15-49 years old) and children (6-59 months old). Most households (90%) reported consuming bouillon, including poor and rural households. At modeled fortification levels, bouillon fortification reduced the national prevalence of inadequacy by up to ∼20 percentage points (pp) for vitamin A, 34 pp (WRA) and 20 pp (children) for folate, 20 pp for vitamin B12, 38 pp (WRA) and 30 pp (children) for zinc, and ∼8 pp for iron. Predicted reductions in inadequacy were generally larger among poor and rural populations, especially for vitamins A and B12. Our modeling suggests that bouillon fortification has the potential to substantially reduce dietary inadequacy of multiple micronutrients and could also help address inequities in dietary micronutrient inadequacies in Senegal.

ABSTRACT

Objective: Physical activity-related interventions alleviate the severity of erectile dysfunction (ED), but it is unknown whether the recommended volume of physical activity (PA) or a higher level of physical activity reduces the likelihood of ED in adult males. We aimed to evaluate the association between the recommended volume of PA and ED among US male adults. Design: A nationally representative cross-sectional survey. Setting: National Health and Nutrition Examination Survey 2001-2004. Participants: A total of 2509 men aged ≥20 years were enrolled. Primary and secondary outcome measures: ED and PA were assessed by a standardised self-report questionnaire. Weighted logistic regression analysis and spline fitting were used to assess the relationship between PA volume and the odds of ED. Results: Among 2509 US adult males, the mean (standard error) age was 43.7 (0.46) years. A total of 61.1 % of men reached the recommended volume of aerobic PA. Compared with participants not meeting the PA guidelines, individuals who had recommended aerobic activities demonstrated a 34 % reduction in the odds of having ED (OR 0.66, 95 % CI 0.48-0.90; p = 0.011). Notably, according to the restricted cubic spline, we revealed a dose‒response pattern between PA volume and reduced odds of ED, even when exceeding the recommended PA levels. When compared to males with moderate-equivalent PA of less than 150 min/week, the odds of ED in those with moderate-equivalent PA levels of 150-300 min/week and >300 min/week decreased by 22 % and 39 %, respectively. Compared with participants who did not meet the PA guidelines, the multivariable-adjusted ORs (95 % CIs) of ED associated with adequate PA volumes were 0.37 (0.22-0.61) among non-smokers and 0.85 (0.57-1.25) among current smokers (p for interaction = 0.023). Conclusions and Relevance: Our findings supported the benefit of meeting the guideline-recommended PA equivalents or higher volumes for ED prevention. However, PA-related benefit might be significantly diminished by smoking.

ABSTRACT

Objective: No standardised approach exists to provide advice after urgent suspected cancer (USC) referral when cancer is not found. This study aimed to assess preferences and acceptability of receiving advice after USC referral related to: 1) managing ongoing symptoms, 2) responding to early symptoms of other cancers, 3) cancer screening, 4) reducing risks of future cancer. Methods: 2,541 patients from two English NHS Trusts were mailed a survey 1-3 months after having no cancer found following urgent suspected gastrointestinal or head and neck cancer referral. Participants were asked about: willingness to receive advice; prospective acceptability; preferences related to mode, timing and who should provide advice; and previous advice receipt. Results: 406 patients responded (16.0%) with 397 in the final analyses. Few participants had previously received advice, yet most were willing to. Willingness varied by type of advice: fewer were willing to receive advice about early symptoms of other cancers (88.9%) than advice related to ongoing symptoms (94.3%). Acceptability was relatively high for all advice types. Reducing the risk of future cancer advice was more acceptable. Acceptability was lower in those from ethnic minority groups, and with lower levels of education. Most participants preferred to receive advice from a doctor; with results or soon after; either face to face or via the telephone. Conclusions: There is a potential unmet need for advice after USC referral when no cancer is found. Equitable intervention design should focus on increasing acceptability for people from ethnic minority groups and those with lower levels of education.
