Effects of ActiGraph's filter, epoch length and non-wearing time algorithm on step counts in people with COPD.

The influence of the ActiGraph® processing criteria on estimating step counts in chronic obstructive pulmonary disease (COPD) remains uncertain. This study aimed to assess the influence of filters, epoch lengths and non-wearing time (NWT) algorithms on steps/day in people with COPD. ActiGraph GT3X+ was worn on the waist for seven days. Steps were detected using different filters (normal and low-frequency extension [LFE]), epoch lengths (15s and 60s), and NWT algorithms (Choi and Troiano). Linear mixed-effects model was applied to assess the effects of filter, epoch length, NWT algorithm on steps/day. Lin's concordance correlation and Bland-Altman were used to measure agreement. A total of 136 people with COPD (107 male; 69 ± 8 years; FEV1 51 ± 17% predicted) were included. Significant differences were found between filters (p < 0.001), but not between epoch lengths or NWT algorithms. The LFE increased, on average, approximately 7500 steps/day compared to the normal filter (p < 0.001). Agreement was poor (<0.3) and proportional bias was significant when comparing steps/day computed with different filters, regardless of the epoch length and NWT algorithm. Filter choice but not epoch lengths or NWT algorithms seem to impact measurement of steps/day. Future studies are needed to recommend the most accurate technique for measuring steps/day in people with COPD.

Factors associated with non-pharmaceutical interventions compliance during COVID-19 pandemic: a Portuguese cross-sectional survey.

BACKGROUND: The use of non-pharmaceutical interventions (NPI) is one of the main tools used in the coronavirus disease 2019 (COVID-19) pandemic response, including physical distancing, frequent hand washing, face mask use, respiratory hygiene and use of contact tracing apps. Literature on compliance with NPI during the COVID-19 pandemic is limited. METHODS: We studied this compliance and associated factors in Portugal, between 28th October 2020 and 11th January 2021 (Portuguese second and third waves of the pandemic), using logistic regressions. Data were collected through a web-based survey and included questions regarding NPI compliance, COVID-19-related concerns, perception of institutions' performance, agreement with the measures implemented and socio-demographic characteristics. RESULTS: From the 1263 eligible responses, we found high levels of compliance among all COVID-19 related NPI, except for the contact tracing app. Females and older participants showed the highest compliance levels, whereas the opposite was observed for previously infected participants. There was heterogeneity of COVID-19 NPI compliance across Portuguese regions and a clear gradient between concern, government performance's perception or agreement and compliance. CONCLUSIONS: Results suggested areas for further study with important implications for pandemic management and communication, for future preparedness, highlighting other factors to be accounted for when recommending policy measures during public health threats.

Effects of change in hospital treatment payment policy for Palestinian refugees in Lebanon: a health economics analysis.

BACKGROUND: In 2016, the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) changed from covering the full cost of secondary care in contracted public and private hospitals in Lebanon, Jordan, to requesting that these hospitals pay 10% of the costs. Meanwhile, services at UNWRA-contracted Palestine Red Crescent Society (PRCS) hospitals remained fully covered. We did a health economics analysis to assess the effects this policy change on the demand for secondary care in UNRWA hospitals. METHODS: We assessed the difference in use of different types of hospital (demand) from January to May, 2016, and June, 2016, to October, 2017, before and after the payment policy change. Data were collected by UNWRA from each hospital's database, including individual-level inpatient information for 22 193 Palestinian refugees in Lebanon who were admitted to secondary care at UNRWA-contracted hospitals (public, private, and PRCS). We used regression analyses to estimate the effects on demand for the different hospital types, length of stay, and total costs of treatment to UNWRA and patients. FINDINGS: Around 64% of patients attended PRCS, 26% private, and 9% public hospitals. According to our econometric estimations, after June, 2016, patients were 16% more likely to choose a PRCS hospital over the other types of hospital. Mean length of stay in PRCS hospitals increased, leading to a 20% chance of patients staying 1 day longer in PRCS hospitals than in public or private hospitals. However, the length of stay in public and private hospitals decreased (by an average of 22% at public and 28% at private hospitals), giving an overall decrease in length of stay of 13%. In terms of bill value (ie, total costs to UNRWA and to patients), we found no difference between before and after the policy change. INTERPRETATION: The introduction of the UNWRA cost-sharing component for secondary care led patients to attend PRCS hospitals more often and for longer periods of time. The finding that no effect was seen on costs for UNRWA or patients suggests that the 10% cut in cover at public and private hospitals did not save any money for UNWRA because patients managed to accommodate the increase by changing their hospital preference The study is limited in that it cannot argue causality between the policy and the results found because there is no control group. Nevertheless, robustness testing, including assessing the year 2017, supports our results. This study contributes to the literature on the impacts of co-payments in health care in a very specific context of poverty and conflict that has rarely been subject to scrutiny and provides feedback to UNRWA on a health-care system measure, relevant for future policy designs. FUNDING: None.

Osteosarcoma-Derived Exosomes as Potential PET Imaging Nanocarriers for Lung Metastasis.

Lung metastases represent the most adverse clinical factor and rank as the leading cause of osteosarcoma-related death. Nearly 80% of patients present lung micrometastasis at diagnosis not detected with current clinical tools. Herein, an exosome (EX)-based imaging tool is developed for lung micrometastasis by positron emission tomography (PET) using osteosarcoma-derived EXs as natural nanocarriers of the positron-emitter copper-64 (64 Cu). Exosomes are isolated from metastatic osteosarcoma cells and functionalized with the macrocyclic chelator NODAGA for complexation with 64 Cu. Surface functionalization has no effect on the physicochemical properties of EXs, or affinity for donor cells and endows them with favorable pharmacokinetics for in vivo studies. Whole-body PET/magnetic resonance imaging (MRI) images in xenografted models show a specific accumulation of 64 Cu-NODAGA-EXs in metastatic lesions as small as 2-3 mm or in a primary tumor, demonstrating the exquisite tropism of EXs for homotypic donor cells. The targetability for lung metastasis is also observed by optical imaging using indocyanine green (ICG)-labeled EXs and D-luciferin-loaded EXs. These findings show that tumor-derived EXs hold great potential as targeted imaging agents for the noninvasive detection of small lung metastasis by PET. This represents a step forward in the biomedical application of EXs in imaging diagnosis with increased translational potential.

Co-payments and equity in care: enhancing hospitalisation policy for Palestine refugees in Lebanon.

BACKGROUND: This paper measures the impact of introducing a 10% co-payment on secondary care hospitalization costs for Palestine refugees living in Lebanon (PRL) in all UNRWA contracted hospitals, except for the Red Crescent Society. This ex-post analysis provides a detailed insight on the direction and magnitude of the policy impact in terms of demand by hospital type, average length of stay and treatment costs. METHODS: With a complete population episode level dataset, we use multinomial logit, negative binomial, and linear models to estimate impacts on the different dependent variables, controlling for disease, patient and hospital characteristics. RESULTS: After the implementation patients were at least 4 pp (p <0.01) more likely to choose a Red Crescent Society hospital for secondary care, instead of one with co-payment. Average length of stay was not affected in general, despite the increase in control at all UNRWA contracted hospitals. Except for the decrease in UNRWA contribution, did not find a statistically significant impact of the co-payment on costs, nor for the provider or for the patient. Findings suggest that introducing a 10% co-payment for secondary hospital care had an impact on patients' health care budget, leading to demand shifts towards cheaper options - i.e., patients had to chose care based on financial constraints rather than on their treatment preferences. CONCLUSION: Before changing healthcare payment schemes in different types of hospitals, facilities offering free of charge treatment should be assessed and prepared for potential demand shifts to avoid overcapacity and the collapse of health care services for such a fragile population. In addition, exemptions from co-payments should be considered for patients with severe health conditions and financial constraints, who, according to our results, are the most likely to change their pattern of care due to an increase in treatment costs.

Applying the Ottawa Ankle Rules in a Pediatric Emergency Department.

OBJECTIVES: Ankle and midfoot injuries constitute one of the most frequent reasons to visit the pediatric emergency department (ED). The aims of the study were (1) to determine the feasibility of the Ottawa Ankle Rules (OARs) in a pediatric ED and its reliability to safely manage ankle and midfoot injuries and (2) to verify the impact in reducing the number of radiographs, healthcare costs, and time spent in the ED. METHODS: The prospective study enrolled 90 patients for the control group and 94 for the case group. For the control group, the standard of practice was registered. In the case group, before beginning enrolment, an instruction of how to apply the OARs were given to all clinicians. After that, OARs were applied according to patient complaints. A follow-up call was made for both groups. RESULTS: The mean age of the control group was 11.9 years (standard deviation, 3.267 years), whereas in the case group was 11.3 years (standard deviation, 3.533 years). Demographic and injury characteristics were similar in both groups. A significant statistical difference was verified in the number of radiographs (P = 0.001) with a reduction of 16.7% in the case group. Patients who did not perform radiography, in the case group, spent at least 1 hour less than the ones who did. The OARs have shown a sensitivity of 100% (95% confidence interval, 39.76-100.00) and specificity of 23.33% (95% CI, 15.06-33.43) with a negative predictive value of 100%. CONCLUSIONS: The OARs are an important clinical instrument with a high sensitivity and negative predictive value, which allows clinicians to avoid unnecessary exposure to radiation without missing clinically relevant fractures.

A Portuguese trial using dignity therapy for adults who have a life-threatening disease: Qualitative analysis of generativity documents.

OBJECTIVES: Dignity therapy (DT) is a brief, individualized intervention, which provides terminally ill patients with an opportunity to convey memories, essential disclosures, and prepare a final generativity document. DT addresses psychosocial and existential issues, enhancing a sense of meaning and purpose. Several studies have considered the legacy topics most frequently discussed by patients near the end of life. To date, no Portuguese study has done that analysis. METHOD: We conducted a qualitative analysis of 17 generativity documents derived from a randomized controlled trial (RCT). Inductive content analysis was used to identify emerging themes. RESULTS: From the 39 RCT participants receiving DT, 17 gave consent for their generativity document to undergo qualitative analysis. Nine patients were female; mean age of 65 years, with a range from 46 to 79 years. Seven themes emerged: "Significant people and things"; "Remarkable moments"; "Acknowledgments"; "Reflection on the course of life"; "Personal values"; "Messages left to others"; and "Requests and last wishes". SIGNIFICANCE OF RESULTS: Generativity document analysis provides useful information for patients nearing death, including their remarkable life moments and memories, core values, concerns, and wishes for their loved ones. Being conscious of these dominant themes may allow health providers to support humanized and personalized care to vulnerable patients and their families, enhancing how professionals perceive and respond to personhood within the clinical setting.

Identification of cattle poisoning by Bifenthrin via earwax analysis by HS/GC-MS.

The use of pyrethroids has increased over recent years, and corresponds to a higher exposure of animals to pesticide residues in the environment and diet. Here, an outbreak of pyrethroid poisoning in beef cattle was reported occurring in Midwestern Brazil. After veterinary evaluation, it was observed that the bovines presented common pyrethroid intoxication symptoms. Aiming to identify the cattle poising by pyrethroid, earwax samples were collected from two groups: exposed and nonexposed animals from the same farm. Blind earwax analyses of the bovines were carried out using headspace/gas chromatography-mass spectrometry (HS/GC-MS). The HS/GC-MS analysis detected the presence of bifenthrin in the earwax analysis of the exposed animals, confirmed by the comparison of its MS fragments with a bifenthrin standard, and also by its retention time relative to the internal standard. In summary, HS/GC-MS analysis of earwax emerges as a tool that can be used in the detection and monitoring of bifenthrin poisoning in cattle, as a useful veterinary diagnosis that ensures animal health and the safety of their products.

Lifestyle-Integrated Functional Exercise for People With Dementia: A Pilot Study.

The objective of this study was to explore the feasibility and preliminary effectiveness of the Lifestyle-Integrated Functional Exercise for People with Dementia (LiFE4D) on health-related physical fitness, cognitive function, physical activity, and respiratory and upper limb functions. A randomized controlled pilot study was conducted (control group: usual care; experimental group: usual care and LiFE4D). The feasibility of LiFE4D was determined considering recruitment, protocol acceptability, adherence, and safety. Measures of health-related physical fitness, cognitive function, physical activity, and respiratory and upper limb functions were assessed at the baseline and 3 months. Twelve participants (8 [66.7%] female, 82 [72.2-84] years) were included, six per group. Recruitment was challenging. LiFE4D was acceptable with excellent adherence and no major adverse events. Cardiorespiratory endurance (effect size = 1.64, 95% confidence interval [CI; 0.33, 2.95]) and balance (effect size = 1.46, 95% CI [0.19, 2.73]) improved after LiFE4D. LiFE4D seems to be feasible and safe, and it shows potential to significantly improve the health-related physical fitness of people with dementia.

In Vivo Tracking of Extracellular Vesicles by Nuclear Imaging: Advances in Radiolabeling Strategies.

Extracellular vesicles (EVs) are naturally secreted vesicles that have attracted a large amount of interest in nanomedicine in recent years due to their innate biocompatibility, high stability, low immunogenicity, and important role in cell-to-cell communication during pathological processes. Their versatile nature holds great potential to improve the treatment of several diseases through their use as imaging biomarkers, therapeutic agents, and drug-delivery vehicles. However, the clinical translation of EV-based approaches requires a better understanding of their in vivo behavior. Several imaging technologies have been used for the non-invasive in vivo tracking of EVs, with a particular emphasis on nuclear imaging due to its high sensitivity, unlimited penetration depth and accurate quantification. In this article, we will review the biological function and inherent characteristics of EVs and provide an overview of molecular imaging modalities used for their in vivo monitoring, with a special focus on nuclear imaging. The advantages of radionuclide-based imaging modalities make them a promising tool to validate the use of EVs in the clinical setting, as they have the potential to characterize in vivo the pharmacokinetics and biological behavior of the vesicles. Furthermore, we will discuss the current methods available for radiolabeling EVs, such as covalent binding, encapsulation or intraluminal labeling and membrane radiolabeling, reporting the advantages and drawbacks of each radiolabeling approach.

Ascaris Suum Infection Downregulates Inflammatory Pathways in the Pig Intestine In Vivo and in Human Dendritic Cells In Vitro.

Ascaris suum is a helminth parasite of pigs closely related to its human counterpart, A. lumbricoides, which infects almost 1 billion people. Ascaris is thought to modulate host immune and inflammatory responses, which may drive immune hyporesponsiveness during chronic infections. Using transcriptomic analysis, we show here that pigs with a chronic A. suum infection have a substantial suppression of inflammatory pathways in the intestinal mucosa, with a broad downregulation of genes encoding cytokines and antigen-processing and costimulatory molecules. A. suum body fluid (ABF) suppressed similar transcriptional pathways in human dendritic cells (DCs) in vitro. DCs exposed to ABF secreted minimal amounts of cytokines and had impaired production of cyclooxygengase-2, altered glucose metabolism, and reduced capacity to induce interferon-gamma production in T cells. Our in vivo and in vitro data provide an insight into mucosal immune modulation during Ascaris infection, and show that A. suum profoundly suppresses immune and inflammatory pathways.

Reliability, Validity, and Ability to Identify Fall Status of the Balance Evaluation Systems Test, Mini-Balance Evaluation Systems Test, and Brief-Balance Evaluation Systems Test in Older People Living in the Community.

OBJECTIVES: To assess the reliability, validity, and ability to identify fall status of the Balance Evaluation Systems Test (BESTest), Mini-BESTest, and Brief-BESTest, compared with the Berg Balance Scale (BBS), in older people living in the community. DESIGN: Cross-sectional. SETTING: Community centers. PARTICIPANTS: Older adults (N=122; mean age ± SD, 76±9y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants reported on falls history in the preceding year and completed the Activities-Specific Balance Confidence (ABC) Scale. The BBS, BESTest, and the Five Times Sit-To-Stand Test were administered. Interrater (2 physiotherapists) and test-retest relative (48-72h) and absolute reliabilities were explored with the intraclass correlation coefficient (ICC) equation (2,1) and the Bland and Altman method. Minimal detectable changes at the 95% confidence level (MDC95) were established. Validity was assessed by correlating the balance tests with each other and with the ABC Scale (Spearman correlation coefficients-ρ). Receiver operating characteristics assessed the ability of each balance test to differentiate between people with and without a history of falls. RESULTS: All balance tests presented good to excellent interrater (ICC=.71-.93) and test-retest (ICC=.50-.82) relative reliability, with no evidence of bias. MDC95 values were 4.6, 9, 3.8, and 4.1 points for the BBS, BESTest, Mini-BESTest, and Brief-BESTest, respectively. All tests were significantly correlated with each other (ρ=.83-.96) and with the ABC Scale (ρ=.46-.61). Acceptable ability to identify fall status (areas under the curve, .71-.78) was found for all tests. Cutoff points were 48.5, 82, 19.5, and 12.5 points for the BBS, BESTest, Mini-BESTest, and Brief-BESTest, respectively. CONCLUSIONS: All balance tests are reliable, valid, and able to identify fall status in older people living in the community. Therefore, the choice of which test to use will depend on the level of balance impairment, purpose, and time availability.

Value for money of medicine sampling and quality testing: evidence from Indonesia.

BACKGROUND: Substandard and falsified medicines (SFMs) are a public health concern of global importance. Postmarket surveillance in the form of medicine sampling and quality testing can prevent and detect SFM, however, there is remarkably scarce evidence about the cost and value for money of these activities: how much do they cost and how effective are they in detecting SFM? METHODS: Between February and October 2022, Systematic Tracking of At Risk Medicines (STARmeds) collected and analysed for quality 1274 samples of 5 medicines from physical and online retail outlets in 7 Indonesian districts. We collated data on the resources consumed by STARmeds, related to all stages of medicines sampling and quality testing including design, fieldwork and laboratory analysis. We used activity-based costing principles to calculate the financial and economic cost of medicine quality surveillance from the perspective of a hypothetical medicines' regulator. We calculated the cost per day and per week of fieldwork, per sample collected and per substandard sample. We used bootstrapping to capture uncertainty in the number of samples collected, by seller location type (urban, rural and online). RESULTS: The total cost of sampling and testing medicines from the market was US$712 964 (current 2022 values). Laboratory costs represented the largest share (70%), followed by other direct costs (12%) and indirect costs (7%). On average, it costs STARmeds US$479 (95% CI US$462 to US$516) to collect one medicine sample and US$5990 (95% CI US$5601 to US$6258) to identify one substandard sample. CONCLUSION: Our findings bring urgently needed and novel information on the cost and value for money of medicine quality surveillance. These may support planning and budgeting of the Indonesian pharmaceutical regulator, but also of regulators and researchers elsewhere, particularly in low-income and middle-income settings, as well as international organisations with health regulation and quality of care remits.

ENPP1 induces blood-brain barrier dysfunction and promotes brain metastasis formation in HER2-positive breast cancer.

BACKGROUND: Brain metastasis (BrM) is a devastating end-stage neurological complication that occurs in up to 50% of HER2+ breast cancer patients. Understanding how disseminating tumor cells manage to cross the blood-brain barrier (BBB) is essential for developing effective preventive strategies. We identified the ecto-nucleotidase ENPP1 as specifically enriched in the secretome of HER2+ brain metastatic cells, prompting us to explore its impact on BBB dysfunction and BrM formation. METHODS: We used in vitro BBB and in vivo premetastatic mouse models to evaluate the effect of tumor-secreted ENPP1 on brain vascular permeability. BBB integrity was analyzed by real-time fluorescence imaging of 20 kDa Cy7.5-dextran extravasation and immunofluorescence staining of adherens and tight junction proteins. Pro-metastatic effects of ENPP1 were evaluated in an experimental brain metastatic model. RESULTS: Systemically secreted ENPP1 from primary breast tumors impaired the integrity of BBB with loss of tight and adherens junction proteins early before the onset of BrM. Mechanistically, ENPP1 induced endothelial cell dysfunction by impairing insulin signaling and its downstream AKT/GSK3ß/ß-catenin pathway. Genetic ablation of ENPP1 from HER2+ brain metastatic cells prevented endothelial cell dysfunction and reduced metastatic burden while prolonging the overall and metastasis-free survival of mice. Furthermore, plasmatic ENPP1 levels correlate with brain metastatic burden and inversely with overall survival. CONCLUSIONS: We demonstrated that metastatic breast cancer cells exploit the ENPP1 signaling for cell transmigration across the BBB and brain colonization. Our data implicate ENPP1 as a potential biomarker for poor prognosis and early detection of BrM in HER2+ breast cancer.

Politics and confidence toward the COVID-19 vaccination: A Brazilian cross-sectional study.

This study has the aim of assessing the Brazilian perceptions, influencing factors and political positioning on the confidence concerning COVID-19 vaccination. To achieve the objective, the methods rely on a cross-sectional survey of Brazilian citizens, distributed through different social networks. The sample is composed of 1,670 valid responses, collected from almost all Brazilian states and state capitals. To analyze the data and give a clear view of the variables' relationship, the study used bivariate and comparative graphs. Results show a higher level of confidence in vaccines from Pfizer and AstraZeneca, while the lower level of confidence is associated with vaccines from Sinopharm and Sputinik5. Vaccine efficacy is the most significant influencing factor that helps in the decision to get vaccinated. Also, individuals are less willing to get vaccinated if their political preferences are related to the right-wing. The results led to three main health and social implications: i) the vaccination strategy campaigns should take in count vaccine efficacy and political aspects; ii) the vaccination process should be adapted to regions with different political positions; and iii) a reinforcement in the educational policies of the vaccine's importance to the public health, to avoid the politization of a health issue.

Retrieving biodiversity data from multiple sources: making secondary data standardised and accessible.

Biodiversity data, particularly species occurrence and abundance, are indispensable for testing empirical hypothesis in natural sciences. However, datasets built for research programmes do not often meet FAIR (findable, accessible, interoperable and reusable) principles, which raises questions about data quality, accuracy and availability. The 21st century has markedly been a new era for data science and analytics and every effort to aggregate, standardise, filter and share biodiversity data from multiple sources have become increasingly necessary. In this study, we propose a framework for refining and conforming secondary biodiversity data to FAIR standards to make them available for use such as macroecological modelling and other studies. We relied on a Darwin Core base model to standardise and further facilitate the curation and validation of data related including the occurrence and abundance of multiple taxa of a region that encompasses estuarine ecosystems in an ecotonal area bordering the easternmost Amazonia. We further discuss the significance of feeding standardised public data repositories to advance scientific progress and highlight their role in contributing to the biodiversity management and conservation.

Influence of Lemongrass Essential Oil (Cymbopogon flexuosus) Supplementation on Diabetes in Rat Model.

(1) Background: Species of the genus Cymbopogon and its essential oil are known for their antioxidant and hypoglycemic effects. This study aimed to investigate the impact of the essential oil of Cymbopogon flexuosus (EOCF), and its major component, citral, on glycemic, lipid, antioxidant parameters, and oxidative stress in a type 1 diabetes (DM1) rat model. (2) Methods: Initially, EOCF was analyzed by Gas chromatography-mass spectrometry (GC-MS) and the antioxidant activity of EOCF and citral was evaluated. Next, male Wistar rats (3 months old, 200-250 g) induced with DM1 using Streptozotocin (STZ) were divided into four groups: negative control supplemented with an 80% Tween solution, two groups of animals supplemented with EOCF (32 mg/kg and 64 mg/kg) and with citral (32 mg/kg), and treated for 14 days. Measurements of blood glucose levels and body weight were taken; after euthanasia, biochemical markers, including lipid profile, uric acid, alanine aminotransferase (ALT), and aspartate aminotransferase (AST), were evaluated. (3) Results: The predominant compounds in EOCF were α-citral (53.21%) and neral (19.42%), constituting 72.63% citral. EOCF showed good antioxidant activity, significantly greater than citral. EOCF supplementation demonstrated a mitigating effect on glycemic, lipid, and hepatic abnormalities induced by DM1. (4) Conclusions: EOCF emerges as a promising therapeutic option for the management of DM1.

Predictors of poor neurodevelopmental outcomes of very preterm and very low birth weight infants.

BACKGROUND: Despite recent improvements, premature infants remain at high risk for long-term morbidity and poorer neurodevelopment, particularly very preterm (VP) and very low birth weight (VLBW). The aim of this study was to describe neurodevelopmental outcomes at two years and identify potential predictors of worse performance. METHODS: In a retrospective cohort, a two-years' neurodevelopmental evaluation was analyzed. Multivariable regressions were used to study the association of perinatal history with neurodevelopmental outcomes. Subjects included VP and/or VLBW born at a Portuguese III-level perinatal center between 2011-2017. Milestones outcomes were assessed using the Griffiths' Mental Development Scales. RESULTS: One hundred seventy-seven infants were included. Two-years milestones were not achieved in 18.6% in language domain and 7.3% in motor function, 4.5% wore glasses and 1.1% auditory prosthesis/cochlear implant. Almost 30% needed intervention, 18.6% occupational therapy, 16.4% physiotherapy and 13.6% speech therapy. Griffiths' Mental Development Scales was performed in 139, with a mean global quotient of 98.3 and hearing/speech as the least quoted scale. Global development delay (GDD) was present in 14.8% and cerebral palsy in 2.8%. Multivariate analysis by logistic regression adjusted to gestational age, birth weight and confounding variables, revealed a statistically significant association between GDD and hydrocephalus with shunt/reservoir (OR:19.01), retinopathy of prematurity stage ≥2 (OR:7.86) and neonatal sepsis (OR:3.34). CONCLUSIONS: Consistent with recent studies, preterm are at increased risk of neurodevelopmental impairment, mainly due to GDD and language delay, rather than cerebral palsy. In this population, hydrocephalus, retinopathy of prematurity and neonatal sepsis were strongly associated with poorer outcomes. Insight into these factors is essential to refer patients for specific early intervention programs.

Influence of Seasonal Hazards on Water, Sanitation, and Hygiene-Related Behavior and Implications for Cholera Transmission in Bangladesh.

Most cholera outbreaks in Bangladesh are seasonal, peaking in the dry and post-monsoon periods. Therefore, we investigated whether changes in water, sanitation, and hygiene (WASH) behavior in three populations in Bangladesh during the year could help explain why these two periods are particular to cholera transmission. The study used a mixed-method design, including a repeated cross-sectional study, focus group discussions, and key informant interviews. Through a repeated cross-sectional study, WASH-related variables were assessed during the dry, monsoon, and control seasons in 600 households from coastal Satkhira, inland Sirajganj, and the Dhaka slums. Seasonal behavioral changes were observed in all study areas. Dhaka and Satkhira had an increased mean distance to water sources during the dry and monsoon seasons (Dhaka: control season, 12 m [95% CI, 11-13]; dry season, 36 m [95% CI, 18-55]; and monsoon season, 180 m [95% CI, 118-243]; Satkhira: control season, 334 m [95% CI, 258-411]; dry season, 669 m [95% CI, 515-822]; and monsoon season, 2,437 m [95% CI, 1,665-3,209]). The participants attributed this to pollution of the usual water source. Perceived water quantity was lowest during the dry season in Dhaka and Sirajganj, and during the monsoon season in Satkhira. Handwashing with soap declined in all areas during the dry and monsoon seasons. Open defecation was frequent among children younger than 5 years, increasing during seasonal climate hazards. Results show that WASH-related behavior changed seasonally, increasing the risk of cholera transmission through multiple hygiene-related transmission pathways. Future research would benefit by ensuring that the length of studies covers all seasons throughout the year and also by looking in more detail at people's behavior and hygiene practices.

Lifestyle integrated functional exercise for people with interstitial lung disease (iLiFE): A mixed-methods feasibility study.

BACKGROUND: People with interstitial lung disease (ILD) present low levels of physical activity (PA) and spend most of their time at home, especially in advanced stages of the disease. The Lifestyle Integrated Functional Exercise for people with ILD (iLiFE) embedding PA in patients' daily routines was developed and implemented. OBJECTIVES: This study aimed to explore the feasibility of iLiFE. METHODS: A pre/post mixed-methods feasibility study was conducted. Feasibility of iLiFE was determined by participant recruitment/retention, adherence, feasibility of outcome measures and adverse events. Measures of PA, sedentary behaviour, balance, muscle strength, functional performance/capacity, exercise capacity, impact of the disease, symptoms (i.e., dyspnoea, anxiety, depression, fatigue and cough) and health-related quality of life were collected at baseline and post-intervention (12-weeks). Semi-structured interviews with participants were conducted in-person immediately after iLiFE. Interviews were audio-recorded, transcribed and analysed by deductive thematic analysis. RESULTS: Ten participants (5♀, 77±3y; FVCpp 77.1 ± 4.4, DLCOpp 42.4 ± 6.6) were included, but only nine completed the study. Recruitment was challenging (30%) and retention high (90%). iLiFE was feasible, with excellent adherence (84.4%) and no adverse events. Missing data were associated with one dropout and non-compliance with the accelerometer (n = 1). Participants reported that iLiFE contributed to (re)gain control in their daily life, namely through improving their well-being, functional status and motivation. Weather, symptoms, physical impairments and lack of motivation were identified as threats to keep an active lifestyle. CONCLUSIONS: iLiFE seems to be feasible, safe and meaningful for people with ILD. A randomised controlled trial is needed to strengthen these promising findings.
