RESUMO

Physical activity monitoring technology (e.g. smartphone apps or wearables) can objectively record physical activity levels, potentially support interventions to increase activity levels, and support the self-management of Chronic Obstructive Pulmonary Disease (COPD). Insight into patients' experiences of monitoring physical activity is needed to inform future healthcare practice and policy utilizing this technology to support long-term positive health behavior change. This scoping review aimed to explore the experiences of using technology for monitoring physical activity among people with COPD. The Joanna Briggs Institute scoping review methodological framework was used. Relevant scientific databases (CINAHL Complete, MEDLINE, PsycINFO, SPORTDiscus, Cochrane Library and Scopus) were searched from 1st January 2016 to 16th March 2021. Thematic synthesis was used to analyze the data. Twelve studies exploring the experiences of people with COPD using technology for monitoring physical activity were included in the synthesis. Seven themes were developed and summarize experiences: 1) Monitoring and keeping track of their activity and health, 2) Supporting motivation to be active, 3) Acceptability of the device, 4) Experiencing technical issues with the device, 5) Setting appropriate and achievable goals for their health condition, 6) Integrating the device into their life and daily routine, and 7) Perceived physical and psychological benefits of using the device. Further high-quality research is needed to understand the experiences of people with COPD using technology to monitor physical activity in everyday life and better self-manage their health condition. Supporting people with COPD to monitor their physical activity could enable them to better self-manage their health condition.

RESUMO

Emicizumab is a bispecific antibody that activates FX to FXa in the absence of FVIII. It has been shown to reduce bleeding episodes in people with haemophilia A complicated by a FVIII inhibitor. Despite the protection against bleeds, some breakthrough bleeds are inevitable and these may require additional haemostatic treatment. Emicizumab has been associated with severe adverse events when co-administered with activated prothrombin complex concentrate. To minimize the risk of adverse events, the UK Haemophilia Centre Doctors' Organisation issues the following updated interim guidance to its Inhibitor Guidelines for managing patients receiving Emicizumab based on the limit published information available in February 2018.

RESUMO

KEY MESSAGE: QTL identified for seedling and adult plant crown rot resistance in four partially resistant hexaploid wheat sources. PCR-based markers identified for use in marker-assisted selection. Crown rot, caused by Fusarium pseudograminearum, is an important disease of wheat in many wheat-growing regions globally. Complete resistance to infection by F. pseudograminearum has not been observed in a wheat host, but germplasm with partial resistance to this pathogen has been identified. The partially resistant wheat hexaploid germplasm sources 2-49, Sunco, IRN497 and CPI133817 were investigated in both seedling and adult plant field trials to identify markers associated with the resistance which could be used in marker-assisted selection programs. Thirteen different quantitative trait loci (QTL) conditioning crown rot resistance were identified in the four different sources. Some QTL were only observed in seedling trials whereas others appeared to be adult plant specific. For example while the QTL on chromosomes 1AS, 1BS, and 4BS contributed by 2-49 and on 2BS contributed by Sunco were detected in both seedling and field trials, the QTL on 1DL present in 2-49 and the QTL on 3BL in IRN497 were only detected in seedling trials. Genetic correlations between field trials of the same population were strong, as were correlations between seedling trials of the same population. Low to moderate correlations were observed between seedling and field trials. Flanking markers, most of which are less than 10 cM apart, have now been identified for each of the regions associated with crown rot resistance.

RESUMO

PURPOSE: The purpose of this study is to assess if diagnosis of type 2 diabetes affected health-related quality of life (HRQoL) among participants in the Diabetes Prevention Program/Diabetes Prevention Program Outcome Study and changes with treatment or diabetes duration. METHODS: 3,210 participants with pre-diabetes were randomized to metformin (MET), intensive lifestyle intervention (ILS), or placebo (PLB). HRQoL was assessed using the SF-36 including: (1) 8 SF-36 subscales; (2) the physical component (PCS) and mental component summary (MCS) scores; and (3) the SF-6D. The sample was categorized by diabetes free versus diagnosed. For diagnosed subgroup, mean scores in the diabetes-free period, at 6 months, 2, 4 and 6 years post-diagnosis, were compared. RESULTS: PCS and SF-6D scores declined in all participants in all treatment arms (P < .001). MCS scores did not change significantly in any treatment arm regardless of diagnosis. ILS participants reported a greater decrease in PCS scores at 6 months post-diagnosis (P < .001) and a more rapid decline immediately post-diagnosis in SF-6D scores (P = .003) than the MET or PLB arms. ILS participants reported a significant decrease in the social functioning subscale at 6 months (P < .001) and two years (P < .001) post-diagnosis. CONCLUSIONS: Participants reported a decline in measures of overall health state (SF-6D) and overall physical HRQoL, whether or not they were diagnosed with diabetes during the study. There was no change in overall mental HRQoL. Participants in the ILS arm with diabetes reported a more significant decline in some HRQoL measures than those in the MET and PLB arms that developed diabetes.

RESUMO

INTRODUCTION: Activity monitors (apps and wearables) are increasingly used by the general population, including people with Chronic Obstructive Pulmonary Disease (COPD). There is potential for activity monitors to support increases in physical activity for people with COPD and healthcare practitioners (HCPs) are likely to be key in supporting their use, but little is currently known about HCPs' views or experiences. This qualitative research aimed to explore HCPs' views and experiences of supporting people with COPD who have used activity monitors. METHODS: Seventeen semi-structured telephone or online interviews were conducted with HCPs between September 2020 and May 2021. HCPs included two nurses, an occupational therapist, a physician, and 13 physiotherapists. Participants were recruited via social media advertisements. They all had experience of supporting people with COPD who had used activity monitors. Interviews were analysed using reflexive thematic analysis. FINDINGS: Four themes were developed highlighting the challenges and benefits of HCPs supporting patients with using activity monitors and utilising patient-collected activity data; 1) Skills and experience are needed to increase accessibility and engagement, 2) Objectively monitored physical activity can support exercise prescription, 3) Applications of activity monitors vary across different settings, and 4) Support is needed for future use of activity monitors. DISCUSSION: HCPs recognised the potential for activity monitors to impact patients' ability to self-manage their COPD. However, there is a lack of guidance and information to support integration within practice. Future research is needed to co-develop information and guidelines for people with COPD and HCPs.

RESUMO

The effect of highways and local activities on the quality of groundwater in Ogun State, Nigeria was investigated. This was done by collecting groundwater samples from three different districts in the state, located in Southwestern Nigeria. The water samples collected at 5 m from the highway and control samples collected at 3 km from the highway were analyzed for the following physicochemical parameters: pH, conductivity, chemical oxygen demand, alkalinity, total hardness, total solid, suspended solid, dissolved solid, chloride, sulfate, phosphate, nitrate, phenol, and the metals-lead, zinc, iron, aluminum, sodium, and potassium. The levels of chromium, copper, and cadmium in the samples were below the detectable limit. The levels of the parameters show that there are significant differences between those in the samples and the controls (F test) except for phosphate and phenol. Also, anthropogenic sources (local activities) elevate the levels of different specific parameters, which are related to these activities. Good correlation was observed between traffic density and lead levels as well as between conductivity and dissolved solids. Comparisons with the World Health Organization guidelines indicate that most of the water samples are not suitable for human consumption.

RESUMO

Chronic kidney disease (CKD) in ageing is a burden on health systems worldwide. Rat models of age-related CKD linked with obesity and hypertension were used to investigate alterations in oxidant handling and energy metabolism to identify gene targets or markers for age-related CKD. Young adult (3 months) and old (21-24 months) spontaneously-hypertensive (SHR), normotensive Wistar-Kyoto (WKY) and Wistar rats (normotensive, obese in ageing) were compared for renal functional and physiological parameters, renal fibrosis and inflammation, oxidative stress (hemeoxygenase-1/HO-1), apoptosis and cell injury (including Bax:Bcl-2), phosphorylated and non-phosphorylated forms of oxidant and energy sensing proteins (p66Shc, AMPK), signal transduction proteins (ERK1/2, PKB), and transcription factors (NF-kappaB, FoxO1). All old rats were normoglycemic. Renal fibrosis, tubular epithelial apoptosis, interstitial macrophages and myofibroblasts (all p<0.05), p66Shc/phospho-p66 (p<0.05), Bax/Bcl-2 ratio (p<0.05) and NF-kappaB expression (p<0.01) were highest in old obese Wistars. Expression of phospho-FoxO/FoxO was elevated in old Wistars (p<0.001) and WKYs (p<0.01). SHRs had high levels in young and old rats. Expression of PKB, phospho-PKB, ERK1/2 and phospho-ERK1/2 were significantly elevated in all aged animals. These results suggest that obesity and hypertension have differing oxidant handling and signalling pathways that act in the pathogenesis of age-related CKD.

RESUMO

The social stigma of sexual immorality is inscripted in constitutions, laws, and statutes in the Caribbean and justified and legitimated through references to Christian doxa. This induces forms of structural stigma through policies and practices of governance. I employ country comparisons to demonstrate the critical effect on rates of HIV/AIDS of structural stigma induced by these inscriptions in Caribbean countries. By comparing rates of HIV/AIDS across selected countries, I analyse the differing patterns of structural stigma against the latter's relationship with structural vulnerabilities associated with poverty, underdevelopment, government incapacities, and population flows. I conclude that significant reductions in rates of prevalence can be achieved when social stigma is minimised or meliorated through effective government action or through the influence of external actors, even in the presence of other forms of structural vulnerabilities. The intensity of population flows into a country can also act independently to increase rates of prevalence, even in the face of reductions in structural stigma related to sexual immorality.

RESUMO

OBJECTIVES: The prevalent genotypes of human papillomavirus (HPV) infection and the significance of HPV16 integration in cervical precancerous lesions and cancer of Chinese women were investigated. METHODS: HPV genotyping and HPV16 integration status were studied on 100 normal cervical cytology, 90 low-grade (LSIL) and 99 high-grade squamous intraepithelial lesions (HSIL), as well as 96 cervical cancer biopsies using DNA sequencing and quantitative real-time PCR. RESULTS: HPV were detected in 12.0% of normal cytology, 93.3% of LSIL, 90.9% of HSIL and 89.6% of cervical cancer samples. High-risk HPV16, 18, 58, 52, 33 and 31 were the 6 major HPV types observed, composing 45.6, 82.8 and 85.4% of HPV infections in LSIL, HSIL and cervical cancers, respectively, with a significant rising trend in increasing disease severity (p = 0.002). While HPV16 and HPV18 were most commonly found in cervical cancer, HPV58 was prevalently observed in cervical precancerous lesions, and its frequency decreased with increased disease severity. Among HPV16-positive patients, 40.0% of LSIL, 88.9% of HSIL and 86.4% of cancer cases had HPV16 integration. The frequency of the integrated form of HPV16 significantly increased with the severity of the disease. CONCLUSIONS: Our results demonstrated that high-risk HPV infection and viral DNA integration were in progressive frequency from low-grade cervical precancerous lesions to cancer. HPV16 integration status had the potential to be a marker for cancer risk assessment of cervical precancerous lesions.

RESUMO

BACKGROUND: American Indian (AI) youth are at high risk for type 2 diabetes. OBJECTIVES: To partner with Eastern Band of Cherokee Indians and Navajo Nation to develop a culturally sensitive behavioural intervention for youth (Tribal Turning Point; TTP) and assess feasibility in an 8-month randomized pilot study. METHODS: We enrolled 62 overweight/obese AI children (7-10 years) who participated with ≥1 parent/primary caregiver. Intervention participants (n = 29) attended 12 group classes and five individual sessions. Control participants (n = 33) attended three health and safety group sessions. We analysed group differences for changes in anthropometrics (BMI, BMI z-score, waist circumference), cardiometabolic (insulin, glucose, blood pressure) and behavioural (physical activity and dietary self-efficacy) outcomes. RESULTS: Study retention was 97%, and intervention group attendance averaged 84%. We observed significant treatment effects (p = 0.02) for BMI and BMI z-score: BMI increased in control (+1.0 kg m-2 , p < 0.001) but not intervention participants (+0.3 kg m-2 , p = 0.13); BMI z-score decreased in intervention (-0.17, p = 0.004) but not control participants (0.01, p = 0.82). There were no treatment effects for cardiometabolic or behavioural outcomes. CONCLUSIONS: We demonstrated that a behavioural intervention is feasible to deliver and improved obesity measures in AI youth. Future work should evaluate TTP for effectiveness, sustainability and long-term impact in expanded tribal settings.

RESUMO

BACKGROUND: Tacrolimus is metabolized by members of the cytochrome p450 3A subfamily, and its bioavailability depends also on P-glycoprotein. We have observed that some patients admitted for infection presented with increased tacrolimus trough levels (TLs). The aim of the study was to assess the impact of infection on tacrolimus TLs and to determine the factors involved in TL fluctuations. METHODS: This retrospective cohort study included patients transplanted with a kidney between 2009 and 2011 who were hospitalized for an acute infection. Tacrolimus TLs and dosages were recorded before hospitalization, at admission, and 1 month after discharge. Increased levels of tacolimus were defined as TL 25% higher on admission than those recorded at the last visit before hospitalization. RESULTS: Seventy-seven patients were hospitalized 138 times for infection. More than two thirds of first hospitalizations occurred during the first post-transplant year. Causes of hospitalization were urinary (33%), cytomegalovirus (27%), digestive (15%), and pulmonary (12%) infections. Thirty-five percent of kidney transplant recipients had increased tacrolimus TLs (27/77 patients) in 24% of the hospitalizations (34/138). In 34 hospitalizations occurring in 27 patients, TL at admission was ≥25% compared with the last visit before admission. Comparing these 34 hospitalizations with the other 104, no significant differences were noted, except for a greater fraction of digestive infections in the group with elevated tacrolimus TLs, independent of diarrhea occurrence. CONCLUSIONS: Up to 35% of kidney transplant recipients admitted for acute infection present with high tacrolimus TLs, requiring a dose reduction. How acute infection precisely affects metabolism and bioavailability of tacrolimus remains to be investigated.

RESUMO

BACKGROUND: Epigenetic gene silencing is one of the major causes of carcinogenesis. Its widespread occurrence in cancer genome could inactivate many cellular pathways including DNA repair, cell cycle control, apoptosis, cell adherence, and detoxification. The abnormal promoter methylation might be a potential molecular marker for cancer management. METHODS: For rapid identification of potential targets for aberrant methylation in gynecological cancers, methylation status of the CpG islands of 34 genes was determined using pooled DNA approach and methylation-specific PCR. Pooled DNA mixture from each cancer type (50 cervical cancers, 50 endometrial cancers and 50 ovarian cancers) was made to form three test samples. The corresponding normal DNA from the patients of each cancer type was also pooled to form the other three control samples. Methylated alleles detected in tumors, but not in normal controls, were indicative of aberrant methylation in tumors. Having identified potential markers, frequencies of methylation were further analyzed in individual samples. Markers identified are used to correlate with clinico-pathological data of tumors using chi2 or Fisher's exact test. RESULTS: APC and p16 were hypermethylated across the three cancers. MINT31 and PTEN were hypermethylated in cervical and ovarian cancers. Specific methylation was found in cervical cancer (including CDH1, DAPK, MGMT and MINT2), endometrial cancer (CASP8, CDH13, hMLH1 and p73), and ovarian cancer (BRCA1, p14, p15, RIZ1 and TMS1). The frequencies of occurrence of hypermethylation in 4 candidate genes in individual samples of each cancer type (DAPK, MGMT, p16 and PTEN in 127 cervical cancers; APC, CDH13, hMLH1 and p16 in 60 endometrial cancers; and BRCA1, p14, p16 and PTEN in 49 ovarian cancers) were examined for further confirmation. Incidence varied among different genes and in different cancer types ranging from the lowest 8.2% (PTEN in ovarian cancer) to the highest 56.7% (DAPK in cervical cancer). Aberrant methylation for some genes (BRCA1, DAPK, hMLH1, MGMT, p14, p16, and PTEN) was also associated with clinico-pathological data. CONCLUSION: Thus, differential methylation profiles occur in the three types of gynecologic cancer. Detection of methylation for critical loci is potentially useful as epigenetic markers in tumor classification. More studies using a much larger sample size are needed to define the potential role of DNA methylation as marker for cancer management.

RESUMO

Less than 1% of the lung cancer cases from the Surveillance, Epidemiology, and End Results (SEER) Program changed categories as a result of the World Health Organization's revision of histologic classifications of lung tumors. Of the 28,119 microscopically proved lung cancers reported to SEER in 1977-79, 32% were squamous cell carcinoma, 16% were small cell and/or oat cell carcinoma, 27% were adenocarcinoma, 8% were large cell carcinoma, and 5% were other specified types. A further 12% (approximately 3,500 cases) were reported with such nonspecific terms as bronchogenic carcinoma, carcinoma of the lung, and undifferentiated or anaplastic carcinoma. The magnitude of the use of these nonspecific terms showed the need for greater precision in reporting and recording data.

RESUMO

Data from nine population-based cancer registries from the National Cancer Institute's Surveillance, Epidemiology, and End Results program of the United States were used to study the incidence of individual histologic types of malignant central nervous system tumors by age and sex among adults. On a log-log scale, incidence increased linearly between the ages 35 and 64, with a slope that was not different between males and females or among registries but that varied by histologic type. The estimated slopes were 0.4 for ependymomas, 1.0 for oligodendrogliomas, 1.7 for astrocytomas, 2.8 for meningiomas, and 3.9 for glioblastomas. The rate at which incidence increased with age was significantly higher for glioblastomas than for other glial tumors. This finding suggests a different mechanism of carcinogenesis for glioblastomas than for other glial tumors.

RESUMO

Incidence rates for pleural and peritoneal mesotheliomas in about 10% of the U.S. population were examined by various demographic characteristics based on 1973-84 data from the Surveillance, Epidemiology, and End Results Program. Although pleural mesothelioma was more common than peritoneal mesothelioma, both are rare diseases in this country. Pleural mesothelioma incidence rates among white males increased over time and were highest in seaboard areas where shipyards have been located (Seattle, San Francisco-Oakland, Hawaii). The significant secular change was attributed to both period (date of diagnosis) and cohort (date of birth) effects. Pleural mesothelioma incidence rates among white males were nearly 50% higher in the 1980-84 period compared to those in 1975-79; the cohort effect rose to a peak for the 1905-9 birth cohort and then declined. These effects probably reflect changes in asbestos exposure patterns in the past and more recent changes in clinical awareness and coding rules for mesothelioma. Geographic analysis of U.S. death certificates for pleural cancer among white males and females dying during 1968-78 indicated that mortality rates were significantly elevated in several areas that have had asbestos-manufacturing plants or shipyards. Analyses of mortality rates must be viewed with caution, since mesothelioma is considerably underreported on death certificates.

RESUMO

Cancer incidence trends from the late 1940s to 1983-84 were assessed among white residents of five geographic areas (Atlanta, Connecticut, Detroit, Iowa, San Francisco-Oakland) by means of data derived from several National Cancer Institute surveys, the Connecticut Tumor Registry, and the Surveillance, Epidemiology, and End Results Program. Incidence trends were compared with mortality trends for the entire United States and for the same five study areas. This study documented rising incidence and mortality rates for four cancers: lung cancer, melanoma of the skin, multiple myeloma, and non-Hodgkin's lymphomas. Increases in lung cancer continued through the early 1980s, but the rate of increase has been moderating during recent years, particularly among males and at younger ages for whom recent declines are evident. Overall, lung cancer incidence rates increased more than 220 and 400% among males and females, respectively. Although much rarer than lung cancer, melanoma of the skin and multiple myeloma increased greatly until the early 1980s among both males and females. The overall rate of increase in melanoma incidence among males was greater than that for lung cancer, and the rate of increase in multiple myeloma mortality among females was exceeded only by that for lung cancer. Increases of 70-120% were observed for non-Hodgkin's lymphomas. Increases in incidence and mortality rates for pancreatic cancer were apparent during the early years but less conspicuous in recent years. Laryngeal and kidney cancer rates generally increased substantially, although the changes were not remarkable for laryngeal cancer mortality among males and kidney cancer mortality among females. The rates for cancers of the mouth and pharynx increased among females but not males. Prostate, colon, and bladder cancer incidence rates increased more than 65% among males, whereas mortality rates changed only moderately. The incidence of thyroid cancer increased more than 75% among both sexes until the late 1970s, but mortality rates have declined during the period of study. Breast cancer incidence increased 30%, whereas mortality rates remained remarkably constant. The incidence of corpus uteri cancer increased dramatically during the mid-1970s and decreased substantially thereafter; these changes were not reflected in the mortality rates, which continually declined during the entire time period. The incidence of testicular cancer increased more than 90% and that of Hodgkin's disease did not change greatly; however, mortality rates for both cancers declined more than 50% since the late 1960s and early 1970s.(ABSTRACT TRUNCATED AT 400 WORDS)

RESUMO

Tree bark species were randomly collected from 65 sites having different anthropogenic activities, such as industrial, high traffic commercial, residential high and residential low traffic volume areas of Ibadan City, Nigeria. Levels of Cd, Cu, Pb, Zn, Co, and Cr of the dry-ashed bark samples were determined by AAS. The mean metal concentrations (mg kg(-1)) in samples from industrial zone were found as Pb: 3.67 ± 1.97, Cd: 0.10 ± 0.07, Zn: 30.96 ± 32.05, Cu: 7.29 ± 5.17, Co: 0.91 ± 0.58, and Cr: 2.61 ± 1.84. The trend of mean trace metal concentrations at high traffic commercial zone follows the order: Zn > Pb > Cu > Cr > Co > Cd. Residential high traffic and low traffic zones revealed the same trend as Cd < Co < Cr < Pb < Cu < Zn. Relatively strong positive correlation between the heavy metals at ρ < 0.05, such as Zn versus Cu (r = 0.79) and Co versus Cu (r = 0.77), was observed. The results of the study suggest that tree bark samples could potentially serve as bioindicators for Cu, Pb, Zn, Cr, and possibly Co and Cd. Furthermore, interspecies variation of heavy metal concentrations in plants barks is recommended.

RESUMO

This paper analyzes recent age-specific trends in brain and other central nervous system cancer mortality from 1968 to 1986-1987 in the United States, United Kingdom, Italy, France, and West Germany. It also examines changes in the use of diagnostic confirmation technology in the U.S. SEER program from 1973 to 1987 to estimate the influence of such factors on recent mortality trends. Other sources of error have not been evaluated in this paper. In the United States and Sweden, deaths due to brain and other central nervous system cancer, adjusted to the overall population, are unchanging. However, age-specific analyses of brain and other nervous system cancer in six major industrial countries show markedly different trends at different age groups, with drastic increases in brain tumor rates in the old: rates doubled in persons ages 75 to 84. In the United States, microscopic or radiographic confirmation occurred throughout this time period in 96% of all incident cases of brain and other central nervous system cancers diagnosed before death in the SEER program, with older persons receiving consistently more radiographic tests than younger persons. The use of diagnostic technology may change over time and across populations, but it is not known to what extent it accounts for these increasing trends, which require careful additional study.

RESUMO

These are only a few of the major findings of this international death certificate study but they should be enough to make epidemiologists and statisticians wary of international mortality figures and to realize that the World Health Organization must put some effort into improving the rules for selecting the underlying cause of death and to training the users to use them in a uniform manner; otherwise the huge and costly effort of revising the ICD-9 into ICD-10 will have been in vain because the mortality figures will not be internationally comparable.
