A qualitative study of a structured approach to prevention and screening - the BETTER WISE project. BMC FAMILY PRACTICE 2021; 22:153. [PMID: 34275453 PMCID: PMC8287802 DOI: 10.1186/s12875-021-01503-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Accepted: 06/22/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND This qualitative study is a sub-component of BETTER WISE, a comprehensive and structured approach that proactively addresses chronic disease prevention, screening, and cancer survivorship, including screening for poverty and addressing lifestyle risks for patients aged 40 to 65. Patients (n = 527) from 13 primary care clinics (urban, rural, and remote) in Alberta, Ontario, and Newfoundland & Labrador, Canada agreed to participate in the study and were invited to a one-hour prevention visit delivered by a Prevention Practitioner (PP) as part of BETTER WISE. We identified the key components of a BETTER WISE prevention visit based on patients' and primary care providers' perspectives. METHODS Primary care providers (PPs, physicians and their staff) participated in 14 focus groups and 19 key informant interviews to share their perspectives on the BETTER WISE project. Of 527 patients who agreed to participate in the study and were invited for a BETTER WISE prevention visit with a PP, we received 356 patient feedback forms. We also collected field notes and memos and employed thematic analysis using a constant comparative method focusing on the BETTER WISE prevention visit. RESULTS We identified four key themes related to a BETTER WISE prevention visit: 1) Creating a safe environment and building trust with patients: PPs provided sufficient time and a safe space for patients to share what was important to them, including their concerns related to poverty, alcohol consumption, and mental health, topics that were often not shared with physicians; 2) Providing personalized health education: PPs used the BETTER WISE tools to provide patients with a personalized overview of their health status and eligible screening; 3) Non-judgmental empowering of patients: Instead of directing patients on what to do, PPs evoked patients' preferences and helped them to set goals (if desired); and 4) Integrating care for patients: PPs clarified information from patients' charts and surveys with physicians and helped patients to navigate resources within and outside of the primary care team. CONCLUSIONS The results of this study underscore the importance of personalized, trusting, non-judgmental, and integrated relationships between primary care providers and patients to effectively address chronic disease prevention, screening, and cancer survivorship as demonstrated by the BETTER WISE prevention visits. TRIAL REGISTRATION This qualitative study is a sub-component of the BETTER WISE pragmatic, cRCT, trial registration ISRCTN21333761 (date of registration 19/12/2016).

Antitumoral synergism between a copper(II) complex and cisplatin improves in vitro and in vivo anticancer activity against melanoma, lung and breast cancer cells. Biochim Biophys Acta Gen Subj 2021; 1865:129963.

Abstract
BACKGROUND Intrinsic resistance of cancer cells is a major concern for the success of chemotherapy, and this undesirable feature stimulates further research into the design of new compounds and/or alternative multiple drug chemotherapy protocols. METHODS In this study, we investigated the antitumoral potential of the coordination compounds [Cu(HPClNOL)Cl]Cl (1), [Fe(HPClNOL)Cl2]NO3(2) and [Mn(HPClNOL)Cl2] (3). Using the human, MCF-7 and A549, and the murine melanoma, B16-F10, cell lines, we determined the cytotoxicity, DCFH oxidation, disruption of mitochondrial membrane potential (ΔΨm), Sub-G1 and TUNEL positive cells, and caspase 8 and 9 activities. Fractional inhibitory concentration (FIC) and xenograft models were also assessed to evaluate the efficacy of antitumoral potential. RESULTS We observed that only complex 1 was cytotoxic. The treatment of cancer cells with complex 1 triggered ROS generation and promoted the disruption of ΔΨm. Complex 1 increased the number of Sub-G1 and TUNEL positive cells, and the measurement of caspase 8 and 9 activity confirmed that apoptosis was triggered by the intrinsic pathway. FIC demonstrated that the combination of complex 1 with cisplatin was additive for the A549 cells whilst it was synergic for MCF-7 and B16-F10. Treatment with complex 1, either alone or combined with cisplatin, reduced tumor growth on xenograft models. CONCLUSIONS The present study brings new clues regarding the mechanism of action of [Cu(HPClNOL)Cl]Cl, either alone or in combination with cisplatin. GENERAL SIGNIFICANCE These results indicate that complex 1, administered either singly or in combination with current drugs, has real potential for use in cancer therapy.

Abstract
BACKGROUND Lymphogranuloma venereum (LGV) is a sexual transmitted infection (STI), currently endemic within the population of men who have sex with men (MSM) of Western Countries. L2B variant has been reported as the predominant strain in the current LGV epidemics, although a shift towards L2-434 has been observed in some European countries. OBJECTIVES To evaluate and characterize the population with LGV infection diagnosed in Centro Hospitalar Universitário de Lisboa Central, Lisbon, Portugal. METHODS A retrospective analysis of all LGV diagnoses between 2016 and 2019 was performed. The diagnosis was established through ompA-genotyping of samples yielding a positive result to Chlamydia trachomatis (CT). All considered samples were retrieved from the clinician activity, through swabbing and urine analysis and CT infection diagnosis was obtained using real-time PCR. RESULTS During the period studied 16 279 CT diagnostics tests were employed, with a striking increase from 2016 (n = 467) to 2019 (n = 9362). A total of 1602 diagnoses of CT were established, from which 168 (10.5%) corresponded to LGV, with both infections showing a rising evolution, between 2016 and 2019, of 2.9 and 2.7 times, respectively. The majority of the LGV strains were genotyped as L2/434 (67.3%; n = 113). LGV predominantly affected MSM and men who have sex with men and women (97.0%; n = 163). Anorectal infection was the most prevalent one (90.5%; n = 152), being proctitis the main clinical presentation (76.2%; n = 128). Absence of symptoms was reported in almost 15% of the cases (n = 24). The presence of concomitant infection with human immunodeficiency virus was dominant (73.2%; n = 123) and the prevalence of one or more STI co-infections was about 60.1% (n = 99). CONCLUSIONS An increasing evolution of CT and LGV testing and diagnosing was observable throughout the studied period. Characteristics of the population are similar with those described within LGV epidemics. In accordance with recent European studies, predominance towards L2 genotype was identified.

Introduction
Modern societies function 24h/day which accounts for shift work (SW) encompassing already more than 20% of the European workforce. While the relationship between blood pressure (BP) and cardiovascular events is a continuous, hypertension (HTN) remains the major preventable cause of cardiovascular disease (CVD) in our continent. SW has been associated with sleep disturbances, circadian misalignment and unhealthy behaviours, possibly conducting to several chronic diseases. Therefore, we aimed to determine if shift workers have higher BP values and/or HTN risk.
Methods
This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search was performed on MEDLINE, EMBASE and Cochrane electronic databases. Included studies reported HTN diagnosis using current thresholds and/or BP values, in both shift workers and in a control group of day workers. SW was categorized in 4 subgroups, focused mostly on night work. Pooled mean difference and 95% Confidence Intervals (95%IC) were estimated for continuous outcomes, Systolic BP (SBP) and diastolic BP (DBP), and pooled Odds Ratio and 95%IC were determined for HTN risk. The Newcastle-Ottawa Quality Assessment Scale was used for quality evaluation of included studies.
Results
Forty-five independent studies were included engaging 117252 workers. Of these, 41 studies were included in the meta-analysis for SBP, 39 for DBP and 14 for HTN. Most studies provided cross-sectional data (n = 42), were developed in Asia (n = 21), in an industrial setting (n = 25) and included only men (n = 26). Most studies were rated as satisfactory quality (n = 23) with confounder adjustment being the weakest parameter.
We found a statically significant increase for both systolic and diastolic BP among permanent night workers, 2.52mmHg [0.75–4.29] and 1.77mmHg [0.39–3.15] respectively. Amongst rotational shift workers, both with and without night work, we found a significant increase only for SBP, namely 1.28 mmHg [0.18–2.39] and 0.65 mmHg [0.07–1.22]. For HTN risk, none of SW types showed significant differences.
Conclusions
Certain groups of shift workers may be at special risk for increased BP. This is the first review assessing the impact of SW specifically on BP values. Although the increases were generally modest, these may play an important role among already susceptible individuals exposed overtime. The effect of SW was more consistent for SBP, which has a major impact on CVD risk. Hence, occupational health services should embrace a holistic CVD preventive approach including atypical risk factors such as SW, with active monitoring across the lifespan of more vulnerable workers.

Abstract
Cervical remodeling is a critical component in both term and preterm labor in eutherian mammals. However, the molecular mechanisms underlying cervical remodeling remain poorly understood in the mare. The current study compared the transcriptome of the equine cervix (cervical mucosa (CM) and stroma (CS)) during placentitis (placentitis group, n = 5) and normal prepartum mares (prepartum group, n = 3) to normal pregnant mares (control group, n = 4). Transcriptome analysis identified differentially expressed genes (DEGs) during placentitis (5310 in CM and 907 in CS) and during the normal prepartum period (189 in CM and 78 in CS). Our study revealed that cervical remodeling during placentitis was dominated by inflammatory signaling as reflected by the overrepresented toll-like receptor signaling, interleukin signaling, T cell activation, and B cell activation pathways. These pathways were accompanied by upregulation of several proteases, including matrix metalloproteinases (MMP1, MMP2, and MMP9), cathepsins (CTSB, CTSC, and CTSD) and a disintegrin and metalloproteinase with thrombospondin type 1 motifs (ADAMTS1, ADAMTS4, and ADAMTS5), which are crucial for degradation of cervical collagens during remodeling. Cervical remodeling during placentitis was also associated with upregulation of water channel-related transcripts (AQP9 and RLN), angiogenesis-related transcripts (NOS3, ENG1, THBS1, and RAC2), and aggrecan (ACAN), a hydrophilic glucosaminoglycan, with subsequent cervical hydration. The normal prepartum cervix was associated with upregulation of ADAMTS1, ADAMTS4, NOS3 and THBS1, which might reflect an early stage of cervical remodeling taking place in preparation for labor. In conclusion, our findings revealed the possible key regulators and mechanisms underlying equine cervical remodeling during placentitis and the normal prepartum period.

Abstract
Introduction Sleep represents an important process in the stable behavioural and emotional functioning of the individual and is an important health indicator. Personality is related with academic and occupational achievement, quality of interpersonal relationships, but also with sleep. Concerning personality, individuals with lower emotional stability have greater sensitivity to stress and maladaptive sleep-related behaviour. Objectives The main goal of this study is to analyze the relation between sleep quality and personality in college students. Methods This study employed a correlational design. A sample of 220 Portuguese students (84.9% females), with mean age of 19.5 years (sd=3.4), from different health courses, filled in the Pittsburgh Sleep Quality Questionnaire and HEXACO-60, during a single individual session. A descriptive statistical analysis, a Pearson correlation analyses and the t Student test, for independent samples, were performed. Results The results showed a predominance of poor sleep quality among students (96.3%). The more prevalent HEXACO dimensions are: Conscientiousness (X=32.6; sd=4.2) and Emotionality (X=31.2; sd=5.2). When exploring personality differences between sleep groups (GSG=Good Sleep Group; PSG=Poor Sleep Group) a significant difference was found in mean scores of the dimension Emotionality. It was observed that the PSG revealed higher levels of Emotionality than the GSG (PSG=31.5; sd=5.1; PSG=26.3; sd=4.0; p<.05). Conclusions College students self-report a poor sleep and the prevalent personality dimensions are Conscientiousness and Emotionality. Students with higher levels of Emotionality (fearfulness, anxiety, dependence and sentimentality) presented a poor sleep. To conclude, mediation studies are needed in order to better understanding the link between personality and sleep.

Abstract
This paper presents the Mechanical Ventilator Milano (MVM), a novel intensive therapy mechanical ventilator designed for rapid, large-scale, low-cost production for the COVID-19 pandemic. Free of moving mechanical parts and requiring only a source of compressed oxygen and medical air to operate, the MVM is designed to support the long-term invasive ventilation often required for COVID-19 patients and operates in pressure-regulated ventilation modes, which minimize the risk of furthering lung trauma. The MVM was extensively tested against ISO standards in the laboratory using a breathing simulator, with good agreement between input and measured breathing parameters and performing correctly in response to fault conditions and stability tests. The MVM has obtained Emergency Use Authorization by U.S. Food and Drug Administration (FDA) for use in healthcare settings during the COVID-19 pandemic and Health Canada Medical Device Authorization for Importation or Sale, under Interim Order for Use in Relation to COVID-19. Following these certifications, mass production is ongoing and distribution is under way in several countries. The MVM was designed, tested, prepared for certification, and mass produced in the space of a few months by a unique collaboration of respiratory healthcare professionals and experimental physicists, working with industrial partners, and is an excellent ventilator candidate for this pandemic anywhere in the world.

Abstract
The COVID-19 pandemic has posed new challenges for the scientific community. The behaviour of the virus and outcomes in people living with HIV have not yet been properly studied. We report the case of a 34-year-old man with newly diagnosed HIV infection stage 4 and asymptomatic SARS-CoV-2 infection. Although immunocompromised patients are classified as being at high risk of developing severe COVID-19, HIV-related immunosuppression may have a protective role. LEARNING POINTS It is important to remember that not every respiratory infection during this pandemic is due to SARS-CoV-2.We need more studies to elucidate the behaviour of COVID-19 in people living with HIV.There is still doubt about the best time for antiretroviral therapy (ART) initiation in this context.

Abstract
Zooplankton are widely recognised as being regulated primarily by predators and food availability. In reservoirs, the quantity and quality of food resources are generally affected by the characteristics of the water, which in turn are controlled by the flow pulse generated by operation of the dams. In this study, we investigated the relationship between zooplankton, water quality and food availability (phytoplankton) in eight hydroelectric reservoirs located in Brazil. Samples were collected during the rainy and dry periods between 2008 and 2009. In general, the reservoirs exhibited mesotrophic conditions and Cyanobacteria were the predominant phytoplankton. The results showed that the rotifers Kellicottia bostoniensis, Hexarthra mira, Keratella spp., and Polyarthra vulgaris were present, indicating nutrient-rich environments. In addition, the copepod Thermocyclops decipiens occurred in eutrophic environments. In contrast, the cladoceran Daphnia gessneri and copepod Notodiaptomus henseni were considered indicators of more desirable water quality, owing to their relationship with waters with lower levels of nutrients and suspended solids. The results support the use of these organisms as a useful tool for understanding changes in water quality and in the ecosystem processes involved.

Abstract
Introduction Contemporary cities face multiple socioenvironmental and health challenges that undermine the efforts to promote healthy environments. The 11th goal – Sustainable cities and communities – of United Nations 2030 Agenda for Sustainable Development states that the presence of nature in cities plays a vital role for its sustainability through public urban green spaces (PUGS) accessible and with quality for all.
Objectives This work describes the application of a grid to evaluate the potential of the ecosystems services (ES) of PUGS.
Methodology The grid was applied in 25 PUGS in the city of Porto, divided into 5 clusters of socioeconomic and environmental deprivation (SED), ranging from very high to very low), and is composed by 6 sections with 37 domains assessed: i) identification; ii) description of the activities; iii) activities that take place; iv) assessment of the environment quality; v) existence of infrastructure and facilities; and vi) security. Dimensions iii, iv, v and vi are filled in the grid by a dichotomous answer: No = 0; Yes = 1. All data calculation and statistical analyses were performed using IBM® SPSS® Statistics vs.25.0. The grid was applied in January 2019 and each PUGS visit lasted 20-25 minutes.
Results The highest total score (33) corresponds to 2 parks located in a low and medium SED clusters. The lowest score (9) corresponds to 2 gardens located in a very high and high SED clusters. The most critical dimension assessed of the PUGS has to do with the activities it offers (Median = 2). On the other hand, the dimension with the highest scores relates to the PUGS environmental quality (Median = 8). Regarding results by SED clusters, it is observed that lowest scores, in all assessed domains, are from PUGS located in high and very high SED clusters.
Conclusion This work presents useful information regarding the importance of promoting PUGS with quality and accessible from all, especially to socioeconomic vulnerable groups, which should be the major goal of public policies designers.

Abstract
Abstract
Background
Digoxin is one of the oldest drugs used in heart failure treatment. It is recommended in patients in sinus rhythm with still symptomatic heart failure with reduced ejection fraction. However, a controversy regarding digoxin use has risen with recent studies demonstrating an increased mortality and arrhythmias rate in patients taking this drug.
Purpose
The purpose of this study is to assess the prognostic impact of digoxin in patients in sinus rhythm with a CRT device, concerning all-cause mortality, hospitalizations due to acute heart failure and rate of ventricular arrhythmias.
Methods
A cohort of 297 consecutive P with advanced HF, sinus rhythm and a CRT device (80% with defibrillator) implanted between February 2004 and January 2016, in a single centre, was included in this retrospective study.
Patients were divided in two groups regarding digoxin prescription (digoxin (DG) and without digoxin (NDG)). A mean clinical follow-up of 5.3 ± 3.4 years regarding long term outcomes was performed. Cox regression was used to identify independent predictors of outcomes.
Results
Digoxin was prescribed in 104 P (35%). In this cohort 67% of P were males and the mean age was 64 ± 11 years. Patients in DG were younger (60 ± 11 vs 66 ± 10, p < 0.001). The 2 groups had similar prevalence of comorbidities, with exception of chronic kidney disease (GD 27.5% vs GND 33.3%, p = 0.05). The etiology was similar between the 2 groups (42% ischaemic).
In the qui-square analysis, there was a statically significant association between the use of digoxin and mortality (DG 42.3% vs NDG 25.4%, p= 0.003), and also between digoxin and hospitalization with acute heart failure (DG 36.5% vs NDG 21.4%, p = 0.005). There was no association between digoxin use and the occurrence of ventricular tachycardia (DG 31.7% vs 40.1%, p = 0.155).
In the Cox proportional hazards regression, accounting for the potential confounders, the use of digoxin was an independent predictor for all-cause mortality (HR = 2.80, CI 95 [1.07 – 7.31], p = 0.036) and also for hospitalization with acute heart failure (HR = 5.82, CI 95 [1.54 – 22.06], p = 0.010).
Conclusion
The use of digoxin was an independent predictor of all-cause mortality and hospitalizations due to acute heart failure. Randomized trials are needed to clarify the impact of digoxin and determine if it is only an indicator of disease severity and worse prognosis or if the drug has a direct negative influence in the natural history of P with heart failure.

Abstract
Fungi of the genus Alternaria are ubiquitous indoor and outdoor airborne agents, and individuals are daily exposed to their spores. Although its importance in human infections and, particularly in respiratory allergies, there are no studies of how Alternaria spp. spores interact with host cells. Our aim was to study the early interaction of Alternaria infectoria spores with macrophages, the first line of immune defense. RAW 264.7 macrophages were infected with A. infectoria conidia, and the internalization and viability of conidia once inside the macrophages were quantified during the first 6 h of interaction. Live cell imaging was used to study the dynamics of this interaction. TNF-α production was quantified by relative gene expression, and the concentration of other cytokines (IL-1α, IL-1β, IL-6, IL-4, IL-10, IL-17, GM-CSF and INF-γ) and a chemokine, MIP-1α, was quantified by ELISA. Conidia were rapidly internalized by macrophages, with approximately half internalized after 30 min of interaction. During the first 6 h of interaction, macrophages retained the ability to mitotically divide while containing internalized conidia. The classical macrophage-activated morphology was absent in macrophages infected with conidia, and TNF-α and other cytokines and chemokines failed to be produced. Thus, macrophages are able to efficiently phagocyte A. infectoria conidia, but, during the first 6 h, no effective antifungal response is triggered, therefore promoting the residence of these fungal conidia inside the macrophages.
